CVE-2026-27606 Severity: Important CVSS3 score: 8.8

Description: Rollup is a module bundler for JavaScript. Versions prior to 2.80.0, 3.30.0, and 4.59.0 of the Rollup module bundler (specifically v4.x and present in current source) is vulnerable to an Arbitrary File Write via Path Traversal. Insecure file name sanitization in the core engine allows an attacker to control output filenames (e.g., via CLI named inputs, manual chunk aliases, or malicious plugins) and use traversal sequences (`../`) to overwrite files anywhere on the host filesystem that the build process has permissions for. This can lead to persistent Remote Code Execution (RCE) by overwriting critical system or user configuration files. Versions 2.80.0, 3.30.0, and 4.59.0 contain a patch for the issue.

CVE-2026-33747 Severity: Important CVSS3 score: 8.4

Description: BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and repeatable manner. Prior to version 0.28.1, when using a custom BuildKit frontend, the frontend can craft an API message that causes files to be written outside of the BuildKit state directory for the execution context. The issue has been fixed in v0.28.1. The vulnerability requires using an untrusted BuildKit frontend set with `#syntax` or `--build-arg BUILDKIT_SYNTAX`. Using these options with a well-known frontend image like `docker/dockerfile` is not affected.

CVE-2026-31402 Severity: Important CVSS3 score: 8.2

Description: In the Linux kernel, the following vulnerability has been resolved:nfsd: fix heap overflow in NFSv4.0 LOCK replay cacheThe NFSv4.0 replay cache uses a fixed 112-byte inline buffer(rp_ibuf[NFSD4_REPLAY_ISIZE]) to store encoded operation responses.This size was calculated based on OPEN responses and does not accountfor LOCK denied responses, which include the conflicting lock owner asa variable-length field up to 1024 bytes (NFS4_OPAQUE_LIMIT).When a LOCK operation is denied due to a conflict with an existing lockthat has a large owner, nfsd4_encode_operation() copies the full encodedresponse into the undersized replay buffer via read_bytes_from_xdr_buf()with no bounds check. This results in a slab-out-of-bounds write of upto 944 bytes past the end of the buffer, corrupting adjacent heap memory.This can be triggered remotely by an unauthenticated attacker with twocooperating NFSv4.0 clients: one sets a lock with a large owner string,then the other requests a conflicting lock to provoke the denial.We could fix this by increasing NFSD4_REPLAY_ISIZE to allow for a fullopaque, but that would increase the size of every stateowner, when mostlockowners are not that large.Instead, fix this by checking the encoded response length againstNFSD4_REPLAY_ISIZE before copying into the replay buffer. If theresponse is too large, set rp_buflen to 0 to skip caching the replaypayload. The status is still cached, and the client already received thecorrect response on the original request.

CVE-2026-34982 Severity: Important CVSS3 score: 8.2

Description: Vim is an open source, command line text editor. Prior to version 9.2.0276, a modeline sandbox bypass in Vim allows arbitrary OS command execution when a user opens a crafted file. The `complete`, `guitabtooltip` and `printheader` options are missing the `P_MLE` flag, allowing a modeline to be executed. Additionally, the `mapset()` function lacks a `check_secure()` call, allowing it to be abused from sandboxed expressions. Commit 9.2.0276 fixes the issue.

CVE-2026-33186 Severity: Important CVSS3 score: 8.1

Description: gRPC-Go is the Go language implementation of gRPC. Versions prior to 1.79.3 have an authorization bypass resulting from improper input validation of the HTTP/2 `:path` pseudo-header. The gRPC-Go server was too lenient in its routing logic, accepting requests where the `:path` omitted the mandatory leading slash (e.g., `Service/Method` instead of `/Service/Method`). While the server successfully routed these requests to the correct handler, authorization interceptors (including the official `grpc/authz` package) evaluated the raw, non-canonical path string. Consequently, "deny" rules defined using canonical paths (starting with `/`) failed to match the incoming request, allowing it to bypass the policy if a fallback "allow" rule was present. This affects gRPC-Go servers that use path-based authorization interceptors, such as the official RBAC implementation in `google.golang.org/grpc/authz` or custom interceptors relying on `info.FullMethod` or `grpc.Method(ctx)`; AND that have a security policy contains specific "deny" rules for canonical paths but allows other requests by default (a fallback "allow" rule). The vulnerability is exploitable by an attacker who can send raw HTTP/2 frames with malformed `:path` headers directly to the gRPC server. The fix in version 1.79.3 ensures that any request with a `:path` that does not start with a leading slash is immediately rejected with a `codes.Unimplemented` error, preventing it from reaching authorization interceptors or handlers with a non-canonical path string. While upgrading is the most secure and recommended path, users can mitigate the vulnerability using one of the following methods: Use a validating interceptor (recommended mitigation); infrastructure-level normalization; and/or policy hardening.

CVE-2026-33416 Severity: Important CVSS3 score: 8.1

Description: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. In versions 1.2.1 through 1.6.55, `png_set_tRNS` and `png_set_PLTE` each alias a heap-allocated buffer between `png_struct` and `png_info`, sharing a single allocation across two structs with independent lifetimes. The `trans_alpha` aliasing has been present since at least libpng 1.0, and the `palette` aliasing since at least 1.2.1. Both affect all prior release lines `png_set_tRNS` sets `png_ptr->trans_alpha = info_ptr->trans_alpha` (256-byte buffer) and `png_set_PLTE` sets `info_ptr->palette = png_ptr->palette` (768-byte buffer). In both cases, calling `png_free_data` (with `PNG_FREE_TRNS` or `PNG_FREE_PLTE`) frees the buffer through `info_ptr` while the corresponding `png_ptr` pointer remains dangling. Subsequent row-transform functions dereference and, in some code paths, write to the freed memory. A second call to `png_set_tRNS` or `png_set_PLTE` has the same effect, because both functions call `png_free_data` internally before reallocating the `info_ptr` buffer. Version 1.6.56 fixes the issue.

CVE-2026-6100 Severity: Important CVSS3 score: 8.1

Description: Use-after-free (UAF) was possible in the `lzma.LZMADecompressor`, `bz2.BZ2Decompressor`, and `gzip.GzipFile` when a memory allocation fails with a `MemoryError` and the decompression instance is re-used. This scenario can be triggered if the process is under memory pressure. The fix cleans up the dangling pointer in this specific error condition.The vulnerability is only present if the program re-uses decompressor instances across multiple decompression calls even after a `MemoryError` is raised during decompression. Using the helper functions to one-shot decompress data such as `lzma.decompress()`, `bz2.decompress()`, `gzip.decompress()`, and `zlib.decompress()` are not affected as a new decompressor instance is used per call. If the decompressor instance is not re-used after an error condition, this usage is similarly not vulnerable.

CVE-2022-50700 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: ath10k: Delay the unmapping of the bufferOn WCN3990, we are seeing a rare scenario where copy engine hardware issending a copy complete interrupt to the host driver while stillprocessing the buffer that the driver has sent, this is leading into anSMMU fault triggering kernel panic. This is happening on copy enginechannel 3 (CE3) where the driver normally enqueues WMI commands to thefirmware. Upon receiving a copy complete interrupt, host driver willimmediately unmap and frees the buffer presuming that hardware hasprocessed the buffer. In the issue case, upon receiving copy completeinterrupt, host driver will unmap and free the buffer but since hardwareis still accessing the buffer (which in this case got unmapped inparallel), SMMU hardware will trigger an SMMU fault resulting in akernel panic.In order to avoid this, as a work around, add a delay before unmappingthe copy engine source DMA buffer. This is conditionally done forWCN3990 and only for the CE3 channel where issue is seen.Below is the crash signature:wifi smmu error: kernel: [ 10.120965] arm-smmu 15000000.iommu: Unhandledcontext fault: fsr=0x402, iova=0x7fdfd8ac0,fsynr=0x500003,cbfrsynra=0xc1, cb=6 arm-smmu 15000000.iommu: Unhandledcontext fault:fsr=0x402, iova=0x7fe06fdc0, fsynr=0x710003,cbfrsynra=0xc1, cb=6 qcom-q6v5-mss 4080000.remoteproc: fatal errorreceived: err_qdi.c:1040:EF:wlan_process:0x1:WLAN RT:0x2091:cmnos_thread.c:3998:Asserted in copy_engine.c:AXI_ERROR_DETECTED:2149remoteproc remoteproc0: crash detected in4080000.remoteproc: type fatal error <3> remoteproc remoteproc0:handling crash #1 in 4080000.remoteprocpc : __arm_lpae_unmap+0x500/0x514lr : __arm_lpae_unmap+0x4bc/0x514sp : ffffffc011ffb530x29: ffffffc011ffb590 x28: 0000000000000000x27: 0000000000000000 x26: 0000000000000004x25: 0000000000000003 x24: ffffffc011ffb890x23: ffffffa762ef9be0 x22: ffffffa77244ef00x21: 0000000000000009 x20: 00000007fff7c000x19: 0000000000000003 x18: 0000000000000000x17: 0000000000000004 x16: ffffffd7a357d9f0x15: 0000000000000000 x14: 00fd5d4fa7ffffffx13: 000000000000000e x12: 0000000000000000x11: 00000000ffffffff x10: 00000000fffffe00x9 : 000000000000017c x8 : 000000000000000cx7 : 0000000000000000 x6 : ffffffa762ef9000x5 : 0000000000000003 x4 : 0000000000000004x3 : 0000000000001000 x2 : 00000007fff7c000x1 : ffffffc011ffb890 x0 : 0000000000000000 Call trace:__arm_lpae_unmap+0x500/0x514__arm_lpae_unmap+0x4bc/0x514__arm_lpae_unmap+0x4bc/0x514arm_lpae_unmap_pages+0x78/0xa4arm_smmu_unmap_pages+0x78/0x104__iommu_unmap+0xc8/0x1e4iommu_unmap_fast+0x38/0x48__iommu_dma_unmap+0x84/0x104iommu_dma_free+0x34/0x50dma_free_attrs+0xa4/0xd0ath10k_htt_rx_free+0xc4/0xf4 [ath10k_core] ath10k_core_stop+0x64/0x7c[ath10k_core]ath10k_halt+0x11c/0x180 [ath10k_core]ath10k_stop+0x54/0x94 [ath10k_core]drv_stop+0x48/0x1c8 [mac80211]ieee80211_do_open+0x638/0x77c [mac80211] ieee80211_open+0x48/0x5c[mac80211]__dev_open+0xb4/0x174__dev_change_flags+0xc4/0x1dcdev_change_flags+0x3c/0x7cdevinet_ioctl+0x2b4/0x580inet_ioctl+0xb0/0x1b4sock_do_ioctl+0x4c/0x16ccompat_ifreq_ioctl+0x1cc/0x35ccompat_sock_ioctl+0x110/0x2ac__arm64_compat_sys_ioctl+0xf4/0x3e0el0_svc_common+0xb4/0x17cel0_svc_compat_handler+0x2c/0x58el0_svc_compat+0x8/0x2cTested-on: WCN3990 hw1.0 SNOC WLAN.HL.2.0-01387-QCAHLSWMTPLZ-1

CVE-2025-21738 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:ata: libata-sff: Ensure that we cannot write outside the allocated bufferreveliofuzzing reported that a SCSI_IOCTL_SEND_COMMAND ioctl with out_lenset to 0xd42, SCSI command set to ATA_16 PASS-THROUGH, ATA command set toATA_NOP, and protocol set to ATA_PROT_PIO, can cause ata_pio_sector() towrite outside the allocated buffer, overwriting random memory.While a ATA device is supposed to abort a ATA_NOP command, there does seemto be a bug either in libata-sff or QEMU, where either this status is notset, or the status is cleared before read by ata_sff_hsm_move().Anyway, that is most likely a separate bug.Looking at __atapi_pio_bytes(), it already has a safety check to ensurethat __atapi_pio_bytes() cannot write outside the allocated buffer.Add a similar check to ata_pio_sector(), such that also ata_pio_sector()cannot write outside the allocated buffer.

CVE-2025-45582 Severity: Important CVSS3 score: 7.8

Description: GNU Tar through 1.35 allows file overwrite via directory traversal in crafted TAR archives, with a certain two-step process. First, the victim must extract an archive that contains a ../ symlink to a critical directory. Second, the victim must extract an archive that contains a critical file, specified via a relative pathname that begins with the symlink name and ends with that critical file's name. Here, the extraction follows the symlink and overwrites the critical file. This bypasses the protection mechanism of "Member name contains '..'" that would occur for a single TAR archive that attempted to specify the critical file via a ../ approach. For example, the first archive can contain "x -> ../../../../../home/victim/.ssh" and the second archive can contain x/authorized_keys. This can affect server applications that automatically extract any number of user-supplied TAR archives, and were relying on the blocking of traversal. This can also affect software installation processes in which "tar xf" is run more than once (e.g., when installing a package can automatically install two dependencies that are set up as untrusted tarballs instead of official packages). NOTE: the official GNU Tar manual has an otherwise-empty directory for each "tar xf" in its Security Rules of Thumb; however, third-party advice leads users to run "tar xf" more than once into the same directory.

CVE-2026-0861 Severity: Important CVSS3 score: 7.8

Description: Passing too large an alignment to the memalign suite of functions (memalign, posix_memalign, aligned_alloc) in the GNU C Library version 2.30 to 2.42 may result in an integer overflow, which could consequently result in a heap corruption.Note that the attacker must have control over both, the size as well as the alignment arguments of the memalign function to be able to exploit this. The size parameter must be close enough to PTRDIFF_MAX so as to overflow size_t along with the large alignment argument. This limits the malicious inputs for the alignment for memalign to the range [1<<62+ 1, 1<<63] and exactly 1<<63 for posix_memalign and aligned_alloc.Typically the alignment argument passed to such functions is a known constrained quantity (e.g. page size, block size, struct sizes) and is not attacker controlled, because of which this may not be easily exploitable in practice. An application bug could potentially result in the input alignment being too large, e.g. due to a different buffer overflow or integer overflow in the application or its dependent libraries, but that is again an uncommon usage pattern given typical sources of alignments.

CVE-2026-23111 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nf_tables: fix inverted genmask check in nft_map_catchall_activate()nft_map_catchall_activate() has an inverted element activity checkcompared to its non-catchall counterpart nft_mapelem_activate() andcompared to what is logically required.nft_map_catchall_activate() is called from the abort path to re-activatecatchall map elements that were deactivated during a failed transaction.It should skip elements that are already active (they don't needre-activation) and process elements that are inactive (they need to berestored). Instead, the current code does the opposite: it skips inactiveelements and processes active ones.Compare the non-catchall activate callback, which is correct: nft_mapelem_activate(): if (nft_set_elem_active(ext, iter->genmask)) return 0; /* skip active, process inactive */With the buggy catchall version: nft_map_catchall_activate(): if (!nft_set_elem_active(ext, genmask)) continue; /* skip inactive, process active */The consequence is that when a DELSET operation is aborted,nft_setelem_data_activate() is never called for the catchall element.For NFT_GOTO verdict elements, this means nft_data_hold() is nevercalled to restore the chain->use reference count. Each abort cyclepermanently decrements chain->use. Once chain->use reaches zero,DELCHAIN succeeds and frees the chain while catchall verdict elementsstill reference it, resulting in a use-after-free.This is exploitable for local privilege escalation from an unprivilegeduser via user namespaces + nftables on distributions that enableCONFIG_USER_NS and CONFIG_NF_TABLES.Fix by removing the negation so the check matches nft_mapelem_activate():skip active elements, process inactive ones.

Description: A flaw was found in systemd. The systemd-machined service contains an Improper Access Control vulnerability due to insufficient validation of the class parameter in the RegisterMachine D-Bus (Desktop Bus) method. A local unprivileged user can exploit this by attempting to register a machine with a specific class value, which may leave behind a usable, attacker-controlled machine object. This allows the attacker to invoke methods on the privileged object, leading to the execution of arbitrary commands with root privileges on the host system.

By passing a malicious payload, the pattern matching will keep backtracking to the input while it doesn't find the closing bracket. As the input size increases, the consumption time will also increase until it causes the application to hang or slow down. There was a merged fix but further testing shows the issue persists. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching. This issue was fixed in version 4.0.8.

CVE-2025-27144 Severity: Important CVSS3 score: 7.5

Description: Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption (JWE), JSON Web Signature (JWS), and JSON Web Token (JWT) standards. In versions on the 4.x branch prior to version 4.0.5, when parsing compact JWS or JWE input, Go JOSE could use excessive memory. The code used strings.Split(token, ".") to split JWT tokens, which is vulnerable to excessive memory consumption when processing maliciously crafted tokens with a large number of `.` characters. An attacker could exploit this by sending numerous malformed tokens, leading to memory exhaustion and a Denial of Service. Version 4.0.5 fixes this issue. As a workaround, applications could pre-validate that payloads passed to Go JOSE do not contain an excessive number of `.` characters.

CVE-2025-38563 Severity: Important CVSS3 score: 7.5

Description: In the Linux kernel, the following vulnerability has been resolved:perf/core: Prevent VMA split of buffer mappingsThe perf mmap code is careful about mmap()'ing the user page with theringbuffer and additionally the auxiliary buffer, when the event supportsit. Once the first mapping is established, subsequent mapping have to usethe same offset and the same size in both cases. The reference counting forthe ringbuffer and the auxiliary buffer depends on this being correct.Though perf does not prevent that a related mapping is split via mmap(2),munmap(2) or mremap(2). A split of a VMA results in perf_mmap_open() calls,which take reference counts, but then the subsequent perf_mmap_close()calls are not longer fulfilling the offset and size checks. This leads toreference count leaks.As perf already has the requirement for subsequent mappings to match theinitial mapping, the obvious consequence is that VMA splits, caused byresizing of a mapping or partial unmapping, have to be prevented.Implement the vm_operations_struct::may_split() callback and returnunconditionally -EINVAL.That ensures that the mapping offsets and sizes cannot be changed after thefact. Remapping to a different fixed address with the same size is stillpossible as it takes the references for the new mapping and drops those ofthe old mapping.

Description: Tornado is a Python web framework and asynchronous networking library. In versions 6.5.2 and below, a single maliciously crafted HTTP request can block the server's event loop for an extended period, caused by the HTTPHeaders.add method. The function accumulates values using string concatenation when the same header name is repeated, causing a Denial of Service (DoS). Due to Python string immutability, each concatenation copies the entire string, resulting in O(n^2) time complexity. The severity can vary from high if max_header_size has been increased from its default, to low if it has its default value of 64KB. This issue is fixed in version 6.5.3.

CVE-2025-67726 Severity: Important CVSS3 score: 7.5

Description: Tornado is a Python web framework and asynchronous networking library. Versions 6.5.2 and below use an inefficient algorithm when parsing parameters for HTTP header values, potentially causing a DoS. The _parseparam function in httputil.py is used to parse specific HTTP header values, such as those in multipart/form-data and repeatedly calls string.count() within a nested loop while processing quoted semicolons. If an attacker sends a request with a large number of maliciously crafted parameters in a Content-Disposition header, the server's CPU usage increases quadratically (O(n^2)) during parsing. Due to Tornado's single event loop architecture, a single malicious request can cause the entire server to become unresponsive for an extended period. This issue is fixed in version 6.5.3.

Description: In the Linux kernel, the following vulnerability has been resolved:ipvs: fix ipv4 null-ptr-deref in route error pathThe IPv4 code path in __ip_vs_get_out_rt() calls dst_link_failure()without ensuring skb->dev is set, leading to a NULL pointer dereferencein fib_compute_spec_dst() when ipv4_link_failure() attempts to sendICMP destination unreachable messages.The issue emerged after commit ed0de45a1008 ("ipv4: recompile ip optionsin ipv4_link_failure") started calling __ip_options_compile() fromipv4_link_failure(). This code path eventually calls fib_compute_spec_dst()which dereferences skb->dev. An attempt was made to fix the NULL skb->devdereference in commit 0113d9c9d1cc ("ipv4: fix null-deref inipv4_link_failure"), but it only addressed the immediate dev_net(skb->dev)dereference by using a fallback device. The fix was incomplete becausefib_compute_spec_dst() later in the call chain still accesses skb->devdirectly, which remains NULL when IPVS calls dst_link_failure().The crash occurs when:1. IPVS processes a packet in NAT mode with a misconfigured destination2. Route lookup fails in __ip_vs_get_out_rt() before establishing a route3.

Description: libcurl can in some circumstances reuse the wrong connection when asked to doan Negotiate-authenticated HTTP or HTTPS request.libcurl features a pool of recent connections so that subsequent requests canreuse an existing connection to avoid overhead.When reusing a connection a range of criterion must first be met. Due to alogical error in the code, a request that was issued by an application couldwrongfully reuse an existing connection to the same server that wasauthenticated using different credentials. One underlying reason being thatNegotiate sometimes authenticates *connections* and not *requests*, contraryto how HTTP is designed to work.An application that allows Negotiate authentication to a server (that respondswanting Negotiate) with `user1:password1` and then does another operation tothe same server also using Negotiate but with `user2:password2` (while theprevious connection is still alive) - the second request wrongly reused thesame connection and since it then sees that the Negotiate negotiation isalready made, it just sends the request over that connection thinking it usesthe user2 credentials when it is in fact still using the connectionauthenticated for user1...The set of authentication methods to use is set with `CURLOPT_HTTPAUTH`.Applications can disable libcurl's reuse of connections and thus mitigate thisproblem, by using one of the following libcurl options to alter howconnections are or are not reused: `CURLOPT_FRESH_CONNECT`,`CURLOPT_MAXCONNECTS` and `CURLMOPT_MAX_HOST_CONNECTIONS` (if using thecurl_multi API).

Description: minimatch is a minimal matching utility for converting glob expressions into JavaScript RegExp objects. Versions 10.2.0 and below are vulnerable to Regular Expression Denial of Service (ReDoS) when a glob pattern contains many consecutive * wildcards followed by a literal character that doesn't appear in the test string. Each * compiles to a separate [^/]*? regex group, and when the match fails, V8's regex engine backtracks exponentially across all possible splits. The time complexity is O(4^N) where N is the number of * characters. With N=15, a single minimatch() call takes ~2 seconds. With N=34, it hangs effectively forever. Any application that passes user-controlled strings to minimatch() as the pattern argument is vulnerable to DoS. This issue has been fixed in version 10.2.1.

They might be called internally by the library when it detects the situation that is subject to connection error. Due to the missing internal state validation, the library keeps reading the rest of the data after one of those APIs is called. Then receiving a malformed frame that causes FRAME_SIZE_ERROR causes assertion failure. nghttp2 v1.68.1 adds missing state validation to avoid assertion failure. No known workarounds are available.

Description: minimatch is a minimal matching utility for converting glob expressions into JavaScript RegExp objects. Prior to version 10.2.3, 9.0.7, 8.0.6, 7.4.8, 6.2.2, 5.1.8, 4.2.5, and 3.1.4, nested `*()` extglobs produce regexps with nested unbounded quantifiers (e.g. `(?:(?:a|b)*)*`), which exhibit catastrophic backtracking in V8. With a 12-byte pattern `*(*(*(a|b)))` and an 18-byte non-matching input, `minimatch()` stalls for over 7 seconds. Adding a single nesting level or a few input characters pushes this to minutes. This is the most severe finding: it is triggered by the default `minimatch()` API with no special options, and the minimum viable pattern is only 12 bytes. The same issue affects `+()` extglobs equally. Versions 10.2.3, 9.0.7, 8.0.6, 7.4.8, 6.2.2, 5.1.8, 4.2.5, and 3.1.4 fix the issue.

Description: pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.3, the `pyasn1` library is vulnerable to a Denial of Service (DoS) attack caused by uncontrolled recursion when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing thousands of nested `SEQUENCE` (`0x30`) or `SET` (`0x31`) tags with "Indefinite Length" (`0x80`) markers. This forces the decoder to recursively call itself until the Python interpreter crashes with a `RecursionError` or consumes all available memory (OOM), crashing the host application. This is a distinct vulnerability from CVE-2026-23490 (which addressed integer overflows in OID decoding).

CVE-2026-31789 Severity: Important CVSS3 score: 7.3

Description: Issue summary: Converting an excessively large OCTET STRING value toa hexadecimal string leads to a heap buffer overflow on 32 bit platforms.Impact summary: A heap buffer overflow may lead to a crash or possiblyan attacker controlled code execution or other undefined behavior.If an attacker can supply a crafted X.509 certificate with an excessivelylarge OCTET STRING value in extensions such as the Subject Key Identifier(SKID) or Authority Key Identifier (AKID) which are being converted to hex,the size of the buffer needed for the result is calculated as multiplicationof the input length by 3. On 32 bit platforms, this multiplication may overflowresulting in the allocation of a smaller buffer and a heap buffer overflow.Applications and services that print or log contents of untrusted X.509certificates are vulnerable to this issue. As the certificates would haveto have sizes of over 1 Gigabyte, printing or logging such certificatesis a fairly unlikely operation and only 32 bit platforms are affected,this issue was assigned Low severity.The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by thisissue, as the affected code is outside the OpenSSL FIPS module boundary.

CVE-2026-41035 Severity: Important CVSS3 score: 7.2

Description: In rsync 3.0.1 through 3.4.1, receive_xattr relies on an untrusted length value during a qsort call, leading to a receiver use-after-free. The victim must run rsync with -X (aka --xattrs). On Linux, many (but not all) common configurations are vulnerable. Non-Linux platforms are more widely vulnerable.

CVE-2026-23191 Severity: Important CVSS3 score: 7.1

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: aloop: Fix racy access at PCM triggerThe PCM trigger callback of aloop driver tries to check the PCM stateand stop the stream of the tied substream in the corresponding cable.Since both check and stop operations are performed outside the cablelock, this may result in UAF when a program attempts to triggerfrequently while opening/closing the tied stream, as spotted byfuzzers.For addressing the UAF, this patch changes two things:- It covers the most of code in loopback_check_format() with cable->lock spinlock, and add the proper NULL checks. This avoids already some racy accesses.- In addition, now we try to check the state of the capture PCM stream that may be stopped in this function, which was the major pain point leading to UAF.

Description: In the Linux kernel, the following vulnerability has been resolved:nvme-pci: fix mempool alloc sizeConvert the max size to bytes to match the units of the divisor thatcalculates the worst-case number of PRP entries.The result is used to determine how many PRP Lists are required. Thecode was previously rounding this to 1 list, but we can require 2 in theworst case. In that scenario, the driver would corrupt memory beyond thesize provided by the mempool.While unlikely to occur (you'd need a 4MB in exactly 127 phys segmentson a queue that doesn't support SGLs), this memory corruption has beenobserved by kfence.

If your firmwareis untrusted realistically there is probably very little you can do toprotect yourself. Still we try to limit the damage as much as possible.Also Smatch marks any data read from the filesystem as untrusted andprints warnings if it not capped correctly.The "code_length * 2" can overflow. The round_up(ucode_size, 16) +sizeof() expression can overflow too. Prevent these overflows.

A reference on the task_struct is not neededbecause requeue_pi_wake_futex() is invoked with a spinlock_t held whichimplies a RCU read section.Even if T1 terminates immediately after, the task_struct will remain validduring T2's wake_up_state(). A READ_ONCE on futex_q::task beforefutex_requeue_pi_complete() is enough because it ensures that the variableis read before the state is updated.Read futex_q::task before updating the requeue state, use it for thefollowing wakeup.

Because of those remainingreferences, the fix in commit f75a2804da39 ("xfrm: destroy xfrm_statesynchronously on net exit path") is not complete.We recently fixed one such situation in TCP due to defered freeing ofskbs (commit 9b6412e6979f ("tcp: drop secpath at the same time as wecurrently drop dst")). This can also happen due to IP reassembly: skbswith a secpath remain on the reassembly queue until netnsdestruction. If we can't guarantee that the queues are flushed by thetime xfrm_state_fini runs, there may still be references to a (user)xfrm_state, preventing the timely deletion of the correspondingfallback state.Instead of chasing each instance of skbs holding a secpath one by one,this patch fixes the issue directly within xfrm, by deleting thefallback state as soon as the last user state depending on it has beendeleted. Destruction will still happen when the final reference isdropped.A separate lockdep class for the fallback state is required sincewe're going to lock x->tunnel while x is locked.

CVE-2025-71089 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:iommu: disable SVA when CONFIG_X86 is setPatch series "Fix stale IOTLB entries for kernel address space", v7.This proposes a fix for a security vulnerability related to IOMMU SharedVirtual Addressing (SVA). In an SVA context, an IOMMU can cache kernelpage table entries. When a kernel page table page is freed andreallocated for another purpose, the IOMMU might still hold stale,incorrect entries. This can be exploited to cause a use-after-free orwrite-after-free condition, potentially leading to privilege escalation ordata corruption.This solution introduces a deferred freeing mechanism for kernel pagetable pages, which provides a safe window to notify the IOMMU toinvalidate its caches before the page is reused.This patch (of 8):In the IOMMU Shared Virtual Addressing (SVA) context, the IOMMU hardwareshares and walks the CPU's page tables. The x86 architecture maps thekernel's virtual address space into the upper portion of every process'spage table. Consequently, in an SVA context, the IOMMU hardware can walkand cache kernel page table entries.The Linux kernel currently lacks a notification mechanism for kernel pagetable changes, specifically when page table pages are freed and reused. The IOMMU driver is only notified of changes to user virtual addressmappings. This can cause the IOMMU's internal caches to retain staleentries for kernel VA.Use-After-Free (UAF) and Write-After-Free (WAF) conditions arise whenkernel page table pages are freed and later reallocated. The IOMMU couldmisinterpret the new data as valid page table entries. The IOMMU mightthen walk into attacker-controlled memory, leading to arbitrary physicalmemory DMA access or privilege escalation. This is also aWrite-After-Free issue, as the IOMMU will potentially continue to writeAccessed and Dirty bits to the freed memory while attempting to walk thestale page tables.Currently, SVA contexts are unprivileged and cannot access kernelmappings. However, the IOMMU will still walk kernel-only page tables allthe way down to the leaf entries, where it realizes the mapping is for thekernel and errors out. This means the IOMMU still caches theseintermediate page table entries, making the described vulnerability a realconcern.Disable SVA on x86 architecture until the IOMMU can receive notificationto flush the paging cache before freeing the CPU kernel page table pages.

Description: In the Linux kernel, the following vulnerability has been resolved:iommu/sva: invalidate stale IOTLB entries for kernel address spaceIntroduce a new IOMMU interface to flush IOTLB paging cache entries forthe CPU kernel address space. This interface is invoked from the x86architecture code that manages combined user and kernel page tables,specifically before any kernel page table page is freed and reused.This addresses the main issue with vfree() which is a common occurrenceand can be triggered by unprivileged users. While this resolves theprimary problem, it doesn't address some extremely rare case related tomemory unplug of memory that was present as reserved memory at boot, whichcannot be triggered by unprivileged users.

CVE-2026-23074 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: Enforce that teql can only be used as root qdiscDesign intent of teql is that it is only supposed to be used as root qdisc.We need to check for that constraint.Although not important, I will describe the scenario that unearthed thisissue for the curious.GangMin Kim managed to concot a scenario as follows:ROOT qdisc 1:0 (QFQ) ├── class 1:1 (weight=15, lmax=16384) netem with delay 6.4s ── class 1:2 (weight=1, lmax=1514) teqlGangMin sends a packet which is enqueued to 1:1 (netem).Any invocation of dequeue by QFQ from this class will not return a packetuntil after 6.4s. In the meantime, a second packet is sent and it lands on1:2. teql's enqueue will return success and this will activate class 1:2.Main issue is that teql only updates the parent visible qlen (sch->q.qlen)at dequeue. Since QFQ will only call dequeue if peek succeeds (and teql'speek always returns NULL), dequeue will never be called and thus the qlenwill remain as 0. With that in mind, when GangMin updates 1:2's lmax value,the qfq_change_class calls qfq_deact_rm_from_agg. Since the child qdisc'sqlen was not incremented, qfq fails to deactivate the class, but stillfrees its pointers from the aggregate. So when the first packet isrescheduled after 6.4 seconds (netem's delay), a dangling pointer isaccessed causing GangMin's causing a UAF.

Description: In the Linux kernel, the following vulnerability has been resolved:perf/core: Fix refcount bug and potential UAF in perf_mmapSyzkaller reported a refcount_t: addition on 0; use-after-free warningin perf_mmap.The issue is caused by a race condition between a failing mmap() setupand a concurrent mmap() on a dependent event (e.g., using outputredirection).In perf_mmap(), the ring_buffer (rb) is allocated and assigned toevent->rb with the mmap_mutex held. The mutex is then released toperform map_range().If map_range() fails, perf_mmap_close() is called to clean up.However, since the mutex was dropped, another thread attaching tothis event (via inherited events or output redirection) can acquirethe mutex, observe the valid event->rb pointer, and attempt toincrement its reference count. If the cleanup path has alreadydropped the reference count to zero, this results in ause-after-free or refcount saturation warning.Fix this by extending the scope of mmap_mutex to cover themap_range() call. This ensures that the ring buffer initializationand mapping (or cleanup on failure) happens atomically effectively,preventing other threads from accessing a half-initialized ordying ring buffer.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: xt_IDLETIMER: reject rev0 reuse of ALARM timer labelsIDLETIMER revision 0 rules reuse existing timers by label and always callmod_timer() on timer->timer.If the label was created first by revision 1 with XT_IDLETIMER_ALARM,the object uses alarm timer semantics and timer->timer is never initialized.Reusing that object from revision 0 causes mod_timer() on an uninitializedtimer_list, triggering debugobjects warnings and possible panic whenpanic_on_warn=1.Fix this by rejecting revision 0 rule insertion when an existing timer withthe same label is of ALARM type.

However, br_cfm_frame_rx() runs insoftirq context under rcu_read_lock (without RTNL) and can re-scheduleccm_rx_dwork via ccm_rx_timer_start() between cancel_delayed_work_sync()returning and kfree_rcu() being called.The following is a simple race scenario: cpu0 cpu1mep_delete_implementation() cancel_delayed_work_sync(ccm_rx_dwork); br_cfm_frame_rx() // peer_mep still in hlist if (peer_mep->ccm_defect) ccm_rx_timer_start() queue_delayed_work(ccm_rx_dwork) hlist_del_rcu(&peer_mep->head); kfree_rcu(peer_mep, rcu); ccm_rx_work_expired() // on freed peer_mepTo prevent this, cancel_delayed_work_sync() is replaced withdisable_delayed_work_sync() in both peer MEP deletion paths, sothat subsequent queue_delayed_work() calls from br_cfm_frame_rx()are silently rejected.The cc_peer_disable() helper retains cancel_delayed_work_sync()because it is also used for the CC enable/disable toggle path wherethe work must remain re-schedulable.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: ctnetlink: fix use-after-free in ctnetlink_dump_exp_ct()ctnetlink_dump_exp_ct() stores a conntrack pointer in cb->data for thenetlink dump callback ctnetlink_exp_ct_dump_table(), but drops theconntrack reference immediately after netlink_dump_start(). When thedump spans multiple rounds, the second recvmsg() triggers the dumpcallback which dereferences the now-freed conntrack via nfct_help(ct),leading to a use-after-free on ct->ext.The bug is that the netlink_dump_control has no .start or .donecallbacks to manage the conntrack reference across dump rounds. Otherdump functions in the same file (e.g. ctnetlink_get_conntrack) properlyuse .start/.done callbacks for this purpose.Fix this by adding .start and .done callbacks that hold and release theconntrack reference for the duration of the dump, and move thenfct_help() call after the cb->args[0] early-return check in the dumpcallback to avoid dereferencing ct->ext unnecessarily.

Description: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Prior to 1.6.55, an out-of-bounds read vulnerability exists in the png_set_quantize() API function. When the function is called with no histogram and the number of colors in the palette is more than twice the maximum supported by the user's display, certain palettes will cause the function to enter into an infinite loop that reads past the end of an internal heap-allocated buffer. The images that trigger this vulnerability are valid per the PNG specification. This vulnerability is fixed in 1.6.55.

CVE-2026-31403 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:NFSD: Hold net reference for the lifetime of /proc/fs/nfs/exports fdThe /proc/fs/nfs/exports proc entry is created at module initand persists for the module's lifetime. exports_proc_open()captures the caller's current network namespace and storesits svc_export_cache in seq->private, but takes no referenceon the namespace. If the namespace is subsequently torn down(e.g. container destruction after the opener does setns() to adifferent namespace), nfsd_net_exit() calls nfsd_export_shutdown()which frees the cache. Subsequent reads on the still-open fddereference the freed cache_detail, walking a freed hash table.Hold a reference on the struct net for the lifetime of the openfile descriptor. This prevents nfsd_net_exit() from running --and thus prevents nfsd_export_shutdown() from freeing the cache-- while any exports fd is open. cache_detail already storesits net pointer (cd->net, set by cache_create_net()), soexports_release() can retrieve it without additional per-filestorage.

CVE-2026-5958 Severity: Moderate CVSS3 score: 6.9

Description: When sed is invoked with both -i (in-place edit) and --follow-symlinks, the function open_next_file() performs two separate, non-atomic filesystem operations on the same path: 1. resolves symlink to its target and stores the resolved path for determining when output is written,2. opens the original symlink path (not the resolved one) to read the file. Between these two calls there is a race window. If an attacker atomically replaces the symlink with a different target during that window, sed will: read content from the new (attacker-chosen) symlink target and write the processed result to the path recorded in step 1. This can lead to arbitrary file overwrite with attacker-controlled content in the context of the sed process.This issue was fixed in version 4.10.

Description: In the Linux kernel, the following vulnerability has been resolved:l2tp: prevent possible tunnel refcount underflowWhen a session is created, it sets a backpointer to its tunnel. Whenthe session refcount drops to 0, l2tp_session_free drops the tunnelrefcount if session->tunnel is non-NULL. However, session->tunnel isset in l2tp_session_create, before the tunnel refcount is incrementedby l2tp_session_register, which leaves a small window wheresession->tunnel is non-NULL when the tunnel refcount hasn't beenbumped.Moving the assignment to l2tp_session_register is trivial butl2tp_session_create calls l2tp_session_set_header_len which usessession->tunnel to get the tunnel's encap. Add an encap arg tol2tp_session_set_header_len to avoid using session->tunnel.If l2tpv3 sessions have colliding IDs, it is possible forl2tp_v3_session_get to race with l2tp_session_register and fetch asession which doesn't yet have session->tunnel set.

CVE-2026-5928 Severity: Moderate CVSS3 score: 6.8

Description: Calling the ungetwc function on a FILE stream with wide characters encoded in a character set that has overlaps between its single byte and multi-byte character encodings, in the GNU C Library version 2.43 or earlier, may result in an attempt to read bytes before an allocated buffer, potentially resulting in unintentional disclosure of neighboring data in the heap, or a program crash.A bug in the wide character pushback implementation (_IO_wdefault_pbackfail in libio/wgenops.c) causes ungetwc() to operate on the regular character buffer (fp->_IO_read_ptr) instead of the actual wide-stream read pointer (fp->_wide_data->_IO_read_ptr). The program crash may happen in cases where fp->_IO_read_ptr is not initialized and hence points to NULL. The buffer under-read requires a special situation where the input character encoding is such that there are overlaps between single byte representations and multibyte representations in that encoding, resulting in spurious matches. The spurious match case is not possible in the standard Unicode character sets.

In both cases, we don't abort the transaction and we release our transaction handle. We jump to the 'fail' label and free the pending snapshot structure. We return with the pending snapshot still in the transaction's list;3) Another task commits the transaction. This time there's no error at all, and then during the transaction commit it accesses a pointer to the pending snapshot structure that the snapshot creation task has already freed, resulting in a user-after-free.This issue could actually be detected by smatch, which produced thefollowing warning: fs/btrfs/ioctl.c:843 create_snapshot() warn: '&pending_snapshot->list' not removed from listSo fix this by not having the snapshot creation ioctl directly add thepending snapshot to the transaction's list. Instead add the pendingsnapshot to the transaction handle, and then at btrfs_commit_transaction()we add the snapshot to the list only when we can guarantee that any errorreturned after that point will result in a transaction abort, in whichcase the ioctl code can safely free the pending snapshot and no one canaccess it anymore.

CVE-2022-49961 Severity: Moderate CVSS3 score: 6.7

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Do mark_chain_precision for ARG_CONST_ALLOC_SIZE_OR_ZEROPrecision markers need to be propagated whenever we have an ARG_CONST_*style argument, as the verifier cannot consider imprecise scalars to beequivalent for the purposes of states_equal check when such argumentsrefine the return value (in this case, set mem_size for PTR_TO_MEM). Theresultant mem_size for the R0 is derived from the constant value, and ifthe verifier incorrectly prunes states considering them equivalent wheresuch arguments exist (by seeing that both registers have reg->precise asfalse in regsafe), we can end up with invalid programs passing theverifier which can do access beyond what should have been the correctmem_size in that explored state.To show a concrete example of the problem:0000000000000000 : 0: r2 = *(u32 *)(r1 + 80) 1: r1 = *(u32 *)(r1 + 76) 2: r3 = r1 3: r3 += 4 4: if r3 > r2 goto +18 5: w2 = 0 6: *(u32 *)(r1 + 0) = r2 7: r1 = *(u32 *)(r1 + 0) 8: r2 = 1 9: if w1 == 0 goto +1 10: r2 = -10000000000000058 : 11: r1 = 0 ll 13: r3 = 0 14: call bpf_ringbuf_reserve 15: if r0 == 0 goto +7 16: r1 = r0 17: r1 += 16777215 18: w2 = 0 19: *(u8 *)(r1 + 0) = r2 20: r1 = r0 21: r2 = 0 22: call bpf_ringbuf_submit00000000000000b8 : 23: w0 = 0 24: exitFor the first case, the single line execution's exploration will prunethe search at insn 14 for the branch insn 9's second leg as it will beverified first using r2 = -1 (UINT_MAX), while as w1 at insn 9 willalways be 0 so at runtime we don't get error for being greater thanUINT_MAX/4 from bpf_ringbuf_reserve. The verifier during regsafe justsees reg->precise as false for both r2 registers in both states, henceconsiders them equal for purposes of states_equal.If we propagated precise markers using the backtracking support, wewould use the precise marking to then ensure that old r2 (UINT_MAX) waswithin the new r2 (1) and this would never be true, so the verificationwould rightfully fail.The end result is that the out of bounds access at instruction 19 wouldbe permitted without this fix.Note that reg->precise is always set to true when user does not haveCAP_BPF (or when subprog count is greater than 1 (i.e. use of any staticor global functions)), hence this is only a problem when precision marksneed to be explicitly propagated (i.e. privileged users with CAP_BPF).A simplified test case has been included in the next patch to preventfuture regressions.

CVE-2023-53338 Severity: Moderate CVSS3 score: 6.7

Description: In the Linux kernel, the following vulnerability has been resolved:lwt: Fix return values of BPF xmit opsBPF encap ops can return different types of positive values, such likeNET_RX_DROP, NET_XMIT_CN, NETDEV_TX_BUSY, and so on, from functionskb_do_redirect and bpf_lwt_xmit_reroute. At the xmit hook, such returnvalues would be treated implicitly as LWTUNNEL_XMIT_CONTINUE inip(6)_finish_output2. When this happens, skbs that have been freed wouldcontinue to the neighbor subsystem, causing use-after-free bug andkernel crashes.To fix the incorrect behavior, skb_do_redirect return values can besimply discarded, the same as tc-egress behavior. On the other hand,bpf_lwt_xmit_reroute returns useful errors to local senders, e.g. PMTUinformation. Thus convert its return values to avoid the conflict withLWTUNNEL_XMIT_CONTINUE.

CVE-2024-49861 Severity: Moderate CVSS3 score: 6.7

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix helper writes to read-only mapsLonial found an issue that despite user- and BPF-side frozen BPF map(like in case of .rodata), it was still possible to write into it froma BPF program side through specific helpers having ARG_PTR_TO_{LONG,INT}as arguments.In check_func_arg() when the argument is as mentioned, the meta->raw_modeis never set. Later, check_helper_mem_access(), under the case ofPTR_TO_MAP_VALUE as register base type, it assumes BPF_READ for thesubsequent call to check_map_access_type() and given the BPF map isread-only it succeeds.The helpers really need to be annotated as ARG_PTR_TO_{LONG,INT} | MEM_UNINITwhen results are written into them as opposed to read out of them. Thelatter indicates that it's okay to pass a pointer to uninitialized memoryas the memory is written to anyway.However, ARG_PTR_TO_{LONG,INT} is a special case of ARG_PTR_TO_FIXED_SIZE_MEMjust with additional alignment requirement. So it is better to just getrid of the ARG_PTR_TO_{LONG,INT} special cases altogether and reuse thefixed size memory types. For this, add MEM_ALIGNED to additionally ensurealignment given these helpers write directly into the args via * = val.The .arg*_size has been initialized reflecting the actual sizeof(*).MEM_ALIGNED can only be used in combination with MEM_FIXED_SIZE annotatedargument types, since in !MEM_FIXED_SIZE cases the verifier does not knowthe buffer size a priori and therefore cannot blindly write * = val.

CVE-2025-21739 Severity: Moderate CVSS3 score: 6.7

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: ufs: core: Fix use-after free in init error and remove pathsdevm_blk_crypto_profile_init() registers a cleanup handler to run whenthe associated (platform-) device is being released. For UFS, thecrypto private data and pointers are stored as part of the ufs_hba'sdata structure 'struct ufs_hba::crypto_profile'. This structure isallocated as part of the underlying ufshcd and therefore Scsi_hostallocation.During driver release or during error handling in ufshcd_pltfrm_init(),this structure is released as part of ufshcd_dealloc_host() before the(platform-) device associated with the crypto call above is released.Once this device is released, the crypto cleanup code will run, usingthe just-released 'struct ufs_hba::crypto_profile'. This causes ause-after-free situation: Call trace: kfree+0x60/0x2d8 (P) kvfree+0x44/0x60 blk_crypto_profile_destroy_callback+0x28/0x70 devm_action_release+0x1c/0x30 release_nodes+0x6c/0x108 devres_release_all+0x98/0x100 device_unbind_cleanup+0x20/0x70 really_probe+0x218/0x2d0In other words, the initialisation code flow is: platform-device probe ufshcd_pltfrm_init() ufshcd_alloc_host() scsi_host_alloc() allocation of struct ufs_hba creation of scsi-host devices devm_blk_crypto_profile_init() devm registration of cleanup handler using platform-deviceand during error handling of ufshcd_pltfrm_init() or during driverremoval: ufshcd_dealloc_host() scsi_host_put() put_device(scsi-host) release of struct ufs_hba put_device(platform-device) crypto cleanup handlerTo fix this use-after free, change ufshcd_alloc_host() to register adevres action to automatically cleanup the underlying SCSI device onufshcd destruction, without requiring explicit calls toufshcd_dealloc_host().

The ftrace_disable is set when an anomaly isdiscovered and to prevent any more damage, ftrace stops all textmodification. The issue that happened was that the ftrace_disable stopsmore than just the text modification.When a module is loaded, its init functions can also be traced. Becausekallsyms deletes the init functions after a module has loaded, ftracesaves them when the module is loaded and function tracing is enabled. Thisallows the output of the function trace to show the init function namesinstead of just their raw memory addresses.When a module is removed, ftrace_release_mod() is called, and ifftrace_disable is set, it just returns without doing anything more. Theproblem here is that it leaves the mod_list still around and if kallsymsis called, it will call into this code and access the module memory thathas already been freed as it will return: strscpy(module_name, mod_map->mod->name, MODULE_NAME_LEN);Where the "mod" no longer exists and triggers a UAF bug.

Description: In the Linux kernel, the following vulnerability has been resolved:mlxsw: spectrum_router: Fix neighbour use-after-freeWe sometimes observe use-after-free when dereferencing a neighbour [1].The problem seems to be that the driver stores a pointer to theneighbour, but without holding a reference on it. A reference is onlytaken when the neighbour is used by a nexthop.Fix by simplifying the reference counting scheme. Always take areference when storing a neighbour pointer in a neighbour entry. Avoidtaking a referencing when the neighbour is used by a nexthop as theneighbour entry associated with the nexthop already holds a reference.Tested by running the test that uncovered the problem over 300 times.Without this patch the problem was reproduced after a handful ofiterations.[1]BUG: KASAN: slab-use-after-free in mlxsw_sp_neigh_entry_update+0x2d4/0x310Read of size 8 at addr ffff88817f8e3420 by task ip/3929CPU: 3 UID: 0 PID: 3929 Comm: ip Not tainted 6.18.0-rc4-virtme-g36b21a067510 #3 PREEMPT(full)Hardware name: Nvidia SN5600/VMOD0013, BIOS 5.13 05/31/2023Call Trace: dump_stack_lvl+0x6f/0xa0 print_address_description.constprop.0+0x6e/0x300 print_report+0xfc/0x1fb kasan_report+0xe4/0x110 mlxsw_sp_neigh_entry_update+0x2d4/0x310 mlxsw_sp_router_rif_gone_sync+0x35f/0x510 mlxsw_sp_rif_destroy+0x1ea/0x730 mlxsw_sp_inetaddr_port_vlan_event+0xa1/0x1b0 __mlxsw_sp_inetaddr_lag_event+0xcc/0x130 __mlxsw_sp_inetaddr_event+0xf5/0x3c0 mlxsw_sp_router_netdevice_event+0x1015/0x1580 notifier_call_chain+0xcc/0x150 call_netdevice_notifiers_info+0x7e/0x100 __netdev_upper_dev_unlink+0x10b/0x210 netdev_upper_dev_unlink+0x79/0xa0 vrf_del_slave+0x18/0x50 do_set_master+0x146/0x7d0 do_setlink.isra.0+0x9a0/0x2880 rtnl_newlink+0x637/0xb20 rtnetlink_rcv_msg+0x6fe/0xb90 netlink_rcv_skb+0x123/0x380 netlink_unicast+0x4a3/0x770 netlink_sendmsg+0x75b/0xc90 __sock_sendmsg+0xbe/0x160 ____sys_sendmsg+0x5b2/0x7d0 ___sys_sendmsg+0xfd/0x180 __sys_sendmsg+0x124/0x1c0 do_syscall_64+0xbb/0xfd0 entry_SYSCALL_64_after_hwframe+0x4b/0x53[...]Allocated by task 109: kasan_save_stack+0x30/0x50 kasan_save_track+0x14/0x30 __kasan_kmalloc+0x7b/0x90 __kmalloc_noprof+0x2c1/0x790 neigh_alloc+0x6af/0x8f0 ___neigh_create+0x63/0xe90 mlxsw_sp_nexthop_neigh_init+0x430/0x7e0 mlxsw_sp_nexthop_type_init+0x212/0x960 mlxsw_sp_nexthop6_group_info_init.constprop.0+0x81f/0x1280 mlxsw_sp_nexthop6_group_get+0x392/0x6a0 mlxsw_sp_fib6_entry_create+0x46a/0xfd0 mlxsw_sp_router_fib6_replace+0x1ed/0x5f0 mlxsw_sp_router_fib6_event_work+0x10a/0x2a0 process_one_work+0xd57/0x1390 worker_thread+0x4d6/0xd40 kthread+0x355/0x5b0 ret_from_fork+0x1d4/0x270 ret_from_fork_asm+0x11/0x20Freed by task 154: kasan_save_stack+0x30/0x50 kasan_save_track+0x14/0x30 __kasan_save_free_info+0x3b/0x60 __kasan_slab_free+0x43/0x70 kmem_cache_free_bulk.part.0+0x1eb/0x5e0 kvfree_rcu_bulk+0x1f2/0x260 kfree_rcu_work+0x130/0x1b0 process_one_work+0xd57/0x1390 worker_thread+0x4d6/0xd40 kthread+0x355/0x5b0 ret_from_fork+0x1d4/0x270 ret_from_fork_asm+0x11/0x20Last potentially related work creation: kasan_save_stack+0x30/0x50 kasan_record_aux_stack+0x8c/0xa0 kvfree_call_rcu+0x93/0x5b0 mlxsw_sp_router_neigh_event_work+0x67d/0x860 process_one_work+0xd57/0x1390 worker_thread+0x4d6/0xd40 kthread+0x355/0x5b0 ret_from_fork+0x1d4/0x270 ret_from_fork_asm+0x11/0x20

CVE-2026-22980 Severity: Moderate CVSS3 score: 6.7

Description: In the Linux kernel, the following vulnerability has been resolved:nfsd: provide locking for v4_end_graceWriting to v4_end_grace can race with server shutdown and result inmemory being accessed after it was freed - reclaim_str_hashtbl inparticularly.We cannot hold nfsd_mutex across the nfsd4_end_grace() call as that isheld while client_tracking_op->init() is called and that can wait foran upcall to nfsdcltrack which can write to v4_end_grace, resulting in adeadlock.nfsd4_end_grace() is also called by the landromat work queue and thisdoesn't require locking as server shutdown will stop the work and waitfor it before freeing anything that nfsd4_end_grace() might access.However, we must be sure that writing to v4_end_grace doesn't restartthe work item after shutdown has already waited for it. For this weadd a new flag protected with nn->client_lock. It is set only while itis safe to make client tracking calls, and v4_end_grace only scheduleswork while the flag is set with the spinlock held.So this patch adds a nfsd_net field "client_tracking_active" which isset as described. Another field "grace_end_forced", is set whenv4_end_grace is written. After this is set, and providingclient_tracking_active is set, the laundromat is scheduled.This "grace_end_forced" field bypasses other checks for whether thegrace period has finished.This resolves a race which can result in use-after-free.

Thus when masking out an erase type, just set theerase size to zero. This will fix the shift-out-of-bounds.[ta: refine changes, new commit message, fix compilation error]

Description: In the Linux kernel, the following vulnerability has been resolved:xfs: fix log recovery buffer allocation for the legacy h_size fixupCommit a70f9fe52daa ("xfs: detect and handle invalid iclog size set bymkfs") added a fixup for incorrect h_size values used for the initialumount record in old xfsprogs versions. Later commit 0c771b99d6c9("xfs: clean up calculation of LR header blocks") cleaned up the logreover buffer calculation, but stoped using the fixed up h_size valueto size the log recovery buffer, which can lead to an out of boundsaccess when the incorrect h_size does not come from the old mkfstool, but a fuzzer.Fix this by open coding xlog_logrec_hblks and taking the fixed h_sizeinto account for this calculation.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: configfs: Prevent OOB read/write in usb_string_copy()Userspace provided string 's' could trivially have the length zero. Leftunchecked this will firstly result in an OOB read in the form`if (str[0 - 1] == '\n') followed closely by an OOB write in the form`str[0 - 1] = '\0'`.There is already a validating check to catch strings that are too long.Let's supply an additional check for invalid strings that are too short.

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-audio: Fix out of bounds reads when finding clock sourcesThe current USB-audio driver code doesn't check bLength of eachdescriptor at traversing for clock descriptors. That is, when adevice provides a bogus descriptor with a shorter bLength, the drivermight hit out-of-bounds reads.For addressing it, this patch adds sanity checks to the validatorfunctions for the clock descriptor traversal. When the descriptorlength is shorter than expected, it's skipped in the loop.For the clock source and clock multiplier descriptors, we can justcheck bLength against the sizeof() of each descriptor type.OTOH, the clock selector descriptor of UAC2 and UAC3 has an arrayof bNrInPins elements and two more fields at its tail, hence thosehave to be checked in addition to the sizeof() check.

CVE-2024-53216 Severity: Moderate CVSS3 score: 6.6

Description: In the Linux kernel, the following vulnerability has been resolved:nfsd: release svc_expkey/svc_export with rcu_workThe last reference for `cache_head` can be reduced to zero in `c_show`and `e_show`(using `rcu_read_lock` and `rcu_read_unlock`). Consequently,`svc_export_put` and `expkey_put` will be invoked, leading to twoissues:1. The `svc_export_put` will directly free ex_uuid. However, `e_show`/`c_show` will access `ex_uuid` after `cache_put`, which can trigger a use-after-free issue, shown below. ================================================================== BUG: KASAN: slab-use-after-free in svc_export_show+0x362/0x430 [nfsd] Read of size 1 at addr ff11000010fdc120 by task cat/870 CPU: 1 UID: 0 PID: 870 Comm: cat Not tainted 6.12.0-rc3+ #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.1-2.fc37 04/01/2014 Call Trace: dump_stack_lvl+0x53/0x70 print_address_description.constprop.0+0x2c/0x3a0 print_report+0xb9/0x280 kasan_report+0xae/0xe0 svc_export_show+0x362/0x430 [nfsd] c_show+0x161/0x390 [sunrpc] seq_read_iter+0x589/0x770 seq_read+0x1e5/0x270 proc_reg_read+0xe1/0x140 vfs_read+0x125/0x530 ksys_read+0xc1/0x160 do_syscall_64+0x5f/0x170 entry_SYSCALL_64_after_hwframe+0x76/0x7e Allocated by task 830: kasan_save_stack+0x20/0x40 kasan_save_track+0x14/0x30 __kasan_kmalloc+0x8f/0xa0 __kmalloc_node_track_caller_noprof+0x1bc/0x400 kmemdup_noprof+0x22/0x50 svc_export_parse+0x8a9/0xb80 [nfsd] cache_do_downcall+0x71/0xa0 [sunrpc] cache_write_procfs+0x8e/0xd0 [sunrpc] proc_reg_write+0xe1/0x140 vfs_write+0x1a5/0x6d0 ksys_write+0xc1/0x160 do_syscall_64+0x5f/0x170 entry_SYSCALL_64_after_hwframe+0x76/0x7e Freed by task 868: kasan_save_stack+0x20/0x40 kasan_save_track+0x14/0x30 kasan_save_free_info+0x3b/0x60 __kasan_slab_free+0x37/0x50 kfree+0xf3/0x3e0 svc_export_put+0x87/0xb0 [nfsd] cache_purge+0x17f/0x1f0 [sunrpc] nfsd_destroy_serv+0x226/0x2d0 [nfsd] nfsd_svc+0x125/0x1e0 [nfsd] write_threads+0x16a/0x2a0 [nfsd] nfsctl_transaction_write+0x74/0xa0 [nfsd] vfs_write+0x1a5/0x6d0 ksys_write+0xc1/0x160 do_syscall_64+0x5f/0x170 entry_SYSCALL_64_after_hwframe+0x76/0x7e2.

CVE-2024-56662 Severity: Moderate CVSS3 score: 6.6

Description: In the Linux kernel, the following vulnerability has been resolved:acpi: nfit: vmalloc-out-of-bounds Read in acpi_nfit_ctlFix an issue detected by syzbot with KASAN:BUG: KASAN: vmalloc-out-of-bounds in cmd_to_func drivers/acpi/nfit/core.c:416 [inline]BUG: KASAN: vmalloc-out-of-bounds in acpi_nfit_ctl+0x20e8/0x24a0drivers/acpi/nfit/core.c:459The issue occurs in cmd_to_func when the call_pkg->nd_reserved2array is accessed without verifying that call_pkg points to a bufferthat is appropriately sized as a struct nd_cmd_pkg. This can leadto out-of-bounds access and undefined behavior if the buffer does nothave sufficient space.To address this, a check was added in acpi_nfit_ctl() to ensure thatbuf is not NULL and that buf_len is less than sizeof(*call_pkg)before accessing it. This ensures safe access to the members ofcall_pkg, including the nd_reserved2 array.

CVE-2024-57890 Severity: Moderate CVSS3 score: 6.6

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/uverbs: Prevent integer overflow issueIn the expression "cmd.wqe_size * cmd.wr_count", both variables are u32values that come from the user so the multiplication can lead to integerwrapping. Then we pass the result to uverbs_request_next_ptr() which alsocould potentially wrap. The "cmd.sge_count * sizeof(struct ib_uverbs_sge)"multiplication can also overflow on 32bit systems although it's fine on64bit systems.This patch does two things. First, I've re-arranged the condition inuverbs_request_next_ptr() so that the use controlled variable "len" is onone side of the comparison by itself without any math. Then I've modifiedall the callers to use size_mul() for the multiplications.

However, during rollback, msg->msg_iter is reset, but sincemsg_pl->sg.size has been increased, subsequent executions will exceed theactual size of msg_iter.'''iov_iter_revert(&msg->msg_iter, msg_pl->sg.size - orig_size);'''The changes in this commit are based on the following considerations:1. When cork_bytes is set, rolling back to non-zero copy logic ispointless and can directly go to zero-copy logic.2. We can not calculate the correct number of bytes to revert msg_iter.Assume the original data is "abcdefgh" (8 bytes), and after 3 pushesby the BPF program, it becomes 11-byte data: "abc?de?fgh?".Then, we set cork_bytes to 6, which means the first 6 bytes have beenprocessed, and the remaining 5 bytes "?fgh?" will be cached until thelength meets the cork_bytes requirement.However, some data in "?fgh?" is not within 'sg->msg_iter'(but in msg_pl instead), especially the data "?" we pushed.So it doesn't seem as simple as just reverting through an offset ofmsg_iter.3. For non-TLS sockets in tcp_bpf_sendmsg, when a "cork" situation occurs,the user-space send() doesn't return an error, and the returned length isthe same as the input length parameter, even if some data is cached.Additionally, I saw that the current non-zero-copy logic for handlingcorking is written as:'''line 1177else if (ret != -EAGAIN) { if (ret == -ENOSPC) ret = 0; goto send_end;'''So it's ok to just return 'copied' without error when a "cork" situationoccurs.

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: SVM: Reject SEV{-ES} intra host migration if vCPU creation is in-flightReject migration of SEV{-ES} state if either the source or destination VMis actively creating a vCPU, i.e. if kvm_vm_ioctl_create_vcpu() is in thesection between incrementing created_vcpus and online_vcpus. The bulk ofvCPU creation runs _outside_ of kvm->lock to allow creating multiple vCPUsin parallel, and so sev_info.es_active can get toggled from false=>true inthe destination VM after (or during) svm_vcpu_create(), resulting in anSEV{-ES} VM effectively having a non-SEV{-ES} vCPU.The issue manifests most visibly as a crash when trying to free a vCPU'sNULL VMSA page in an SEV-ES VM, but any number of things can go wrong.

Description: In the Linux kernel, the following vulnerability has been resolved:PCI/IOV: Fix race between SR-IOV enable/disable and hotplugCommit 05703271c3cd ("PCI/IOV: Add PCI rescan-remove locking whenenabling/disabling SR-IOV") tried to fix a race between the VF removalinside sriov_del_vfs() and concurrent hot unplug by taking the PCIrescan/remove lock in sriov_del_vfs(). Similarly the PCI rescan/remove lockwas also taken in sriov_add_vfs() to protect addition of VFs.This approach however causes deadlock on trying to remove PFs with SR-IOVenabled because PFs disable SR-IOV during removal and this removal happensunder the PCI rescan/remove lock. So the original fix had to be reverted.Instead of taking the PCI rescan/remove lock in sriov_add_vfs() andsriov_del_vfs(), fix the race that occurs with SR-IOV enable and disable vshotplug higher up in the callchain by taking the lock insriov_numvfs_store() before calling into the driver's sriov_configure()callback.

CVE-2025-71113 Severity: Moderate CVSS3 score: 6.6

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: af_alg - zero initialize memory allocated via sock_kmallocSeveral crypto user API contexts and requests allocated withsock_kmalloc() were left uninitialized, relying on callers toset fields explicitly. This resulted in the use of uninitializeddata in certain error paths or when new fields are added in thefuture.The ACVP patches also contain two user-space interface files:algif_kpp.c and algif_akcipher.c. These too rely on properinitialization of their context structures.A particular issue has been observed with the newly added'inflight' variable introduced in af_alg_ctx by commit: 67b164a871af ("crypto: af_alg - Disallow multiple in-flight AIO requests")Because the context is not memset to zero after allocation,the inflight variable has contained garbage values. As a result,af_alg_alloc_areq() has incorrectly returned -EBUSY randomly whenthe garbage value was interpreted as true: https://github.com/gregkh/linux/blame/master/crypto/af_alg.c#L1209The check directly tests ctx->inflight without explicitlycomparing against true/false. Since inflight is only ever set totrue or false later, an uninitialized value has triggered-EBUSY failures. Zero-initializing memory allocated withsock_kmalloc() ensures inflight and other fields start in a knownstate, removing random issues caused by uninitialized data.

Description: Vim is an open source, command line text editor. Prior to version 9.1.2132, a heap buffer overflow vulnerability exists in Vim's tag file resolution logic when processing the 'helpfile' option. The vulnerability is located in the get_tagfname() function in src/tag.c. When processing help file tags, Vim copies the user-controlled 'helpfile' option value into a fixed-size heap buffer of MAXPATHL + 1 bytes (typically 4097 bytes) using an unsafe STRCPY() operation without any bounds checking. This issue has been patched in version 9.1.2132.

Description: In the Linux kernel, the following vulnerability has been resolved:sctp: check send stream number after wait_for_sndbufThis patch fixes a corner case where the asoc out stream count may changeafter wait_for_sndbuf.When the main thread in the client starts a connection, if its out streamcount is set to N while the in stream count in the server is set to N - 2,another thread in the client keeps sending the msgs with stream numberN - 1, and waits for sndbuf before processing INIT_ACK.However, after processing INIT_ACK, the out stream count in the client isshrunk to N - 2, the same to the in stream count in the server. The crashoccurs when the thread waiting for sndbuf is awake and sends the msg in anon-existing stream(N - 1), the call trace is as below: KASAN: null-ptr-deref in range [0x0000000000000038-0x000000000000003f] Call Trace: sctp_cmd_send_msg net/sctp/sm_sideeffect.c:1114 [inline] sctp_cmd_interpreter net/sctp/sm_sideeffect.c:1777 [inline] sctp_side_effects net/sctp/sm_sideeffect.c:1199 [inline] sctp_do_sm+0x197d/0x5310 net/sctp/sm_sideeffect.c:1170 sctp_primitive_SEND+0x9f/0xc0 net/sctp/primitive.c:163 sctp_sendmsg_to_asoc+0x10eb/0x1a30 net/sctp/socket.c:1868 sctp_sendmsg+0x8d4/0x1d90 net/sctp/socket.c:2026 inet_sendmsg+0x9d/0xe0 net/ipv4/af_inet.c:825 sock_sendmsg_nosec net/socket.c:722 [inline] sock_sendmsg+0xde/0x190 net/socket.c:745The fix is to add an unlikely check for the send stream number after thethread wakes up from the wait_for_sndbuf.

CVE-2023-53539 Severity: Moderate CVSS3 score: 6.5

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/rxe: Fix incomplete state save in rxe_requesterIf a send packet is dropped by the IP layer in rxe_requester()the call to rxe_xmit_packet() can fail with err == -EAGAIN.To recover, the state of the wqe is restored to the state beforethe packet was sent so it can be resent. However, the routinesthat save and restore the state miss a significnt part of thevariable state in the wqe, the dma struct which is used to processthrough the sge table. And, the state is not saved before the packetis built which modifies the dma struct.Under heavy stress testing with many QPs on a fast node sendinglarge messages to a slow node dropped packets are observed andthe resent packets are corrupted because the dma struct was notrestored. This patch fixes this behavior and allows the test casesto succeed.

I originally looked for the same pattern elsewhere inour code, but mistakenly skipped over this code because I saw the pagecache readahead before we set_page_extent_mapped, not realizing thatthis was only in the !page case, that we can still end up with a!uptodate page and then do the btrfs_read_folio further down.The fix here is the same as the above mentioned patch, move theset_page_extent_mapped call to after the btrfs_read_folio() block tomake sure that we have the subpage blocksize stuff setup properly beforeusing the page.

CVE-2024-27415 Severity: Moderate CVSS3 score: 6.5

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: bridge: confirm multicast packets before passing them up the stackconntrack nf_confirm logic cannot handle cloned skbs referencingthe same nf_conn entry, which will happen for multicast (broadcast)frames on bridges. Example: macvlan0 | br0 / \ ethX ethY ethX (or Y) receives a L2 multicast or broadcast packet containing an IP packet, flow is not yet in conntrack table. 1. skb passes through bridge and fake-ip (br_netfilter)Prerouting. -> skb->_nfct now references a unconfirmed entry 2. skb is broad/mcast packet. bridge now passes clones out on each bridge interface. 3. skb gets passed up the stack. 4. In macvlan case, macvlan driver retains clone(s) of the mcast skb and schedules a work queue to send them out on the lower devices. The clone skb->_nfct is not a copy, it is the same entry as the original skb. The macvlan rx handler then returns RX_HANDLER_PASS. 5. Normal conntrack hooks (in NF_INET_LOCAL_IN) confirm the orig skb.The Macvlan broadcast worker and normal confirm path will race.This race will not happen if step 2 already confirmed a clone. In thatcase later steps perform skb_clone() with skb->_nfct already confirmed (inhash table). This works fine.But such confirmation won't happen when eb/ip/nftables rules dropped thepackets before they reached the nf_confirm step in postrouting.Pablo points out that nf_conntrack_bridge doesn't allow use of statefulnat, so we can safely discard the nf_conn entry and let inet callconntrack again.This doesn't work for bridge netfilter: skb could have a nattransformation. Also bridge nf prevents re-invocation of inet preroutingvia 'sabotage_in' hook.Work around this problem by explicit confirmation of the entry at LOCAL_INtime, before upper layer has a chance to clone the unconfirmed entry.The downside is that this disables NAT and conntrack helpers.Alternative fix would be to add locking to all code parts that deal withunconfirmed packets, but even if that could be done in a sane way thisopens up other problems, for example:-m physdev --physdev-out eth0 -j SNAT --snat-to 1.2.3.4-m physdev --physdev-out eth1 -j SNAT --snat-to 1.2.3.5For multicast case, only one of such conflicting mappings will becreated, conntrack only handles 1:1 NAT mappings.Users should set create a setup that explicitly marks such trafficNOTRACK (conntrack bypass) to avoid this, but we cannot auto-bypassthem, ruleset might have accept rules for untracked traffic already,so user-visible behaviour would change.

Due to the different implementations depending on thearchitecture, page_address(NULL) will trigger a panic on Loongarchplatform but not on x86 platform. So this bug was hidden on x86 platformfor a while, but now it is exposed on Loongarch platform. The root causeis that a zero length skb (skb->len == 0) was put on the queue.This zero length skb is a TCP FIN packet, which was sent by shutdown(),invoked in test_sockmap_skb_verdict_shutdown(): shutdown(p1, SHUT_WR);In this case, in sk_psock_skb_ingress_enqueue(), num_sge is zero, and nopage is put to this sge (see sg_set_page in sg_set_page), but this emptysge is queued into ingress_msg list.And in sk_msg_recvmsg(), this empty sge is used, and a NULL page is got bysg_page(sge). Pass this NULL page to copy_page_to_iter(), which passes itto kmap_local_page() and to page_address(), then kernel panics.To solve this, we should skip this zero length skb. So in sk_msg_recvmsg(),if copy is zero, that means it's a zero length skb, skip invokingcopy_page_to_iter(). We are using the EFAULT return triggered bycopy_page_to_iter to check for is_fin in tcp_bpf.c.

CVE-2025-38512 Severity: Moderate CVSS3 score: 6.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: prevent A-MSDU attacks in mesh networksThis patch is a mitigation to prevent the A-MSDU spoofing vulnerabilityfor mesh networks. The initial update to the IEEE 802.11 standard, inresponse to the FragAttacks, missed this case (CVE-2025-27558). It canbe considered a variant of CVE-2020-24588 but for mesh networks.This patch tries to detect if a standard MSDU was turned into an A-MSDUby an adversary. This is done by parsing a received A-MSDU as a standardMSDU, calculating the length of the Mesh Control header, and seeing ifthe 6 bytes after this header equal the start of an rfc1042 header. Ifequal, this is a strong indication of an ongoing attack attempt.This defense was tested with mac80211_hwsim against a mesh network thatuses an empty Mesh Address Extension field, i.e., when four addressesare used, and when using a 12-byte Mesh Address Extension field, i.e.,when six addresses are used. Functionality of normal MSDUs and A-MSDUswas also tested, and confirmed working, when using both an empty and12-byte Mesh Address Extension field.It was also tested with mac80211_hwsim that A-MSDU attacks in non-meshnetworks keep being detected and prevented.Note that the vulnerability being patched, and the defense beingimplemented, was also discussed in the following paper and in thefollowing IEEE 802.11 presentation:https://papers.mathyvanhoef.com/wisec2025.pdfhttps://mentor.ieee.org/802.11/dcn/25/11-25-0949-00-000m-a-msdu-mesh-spoof-protection.docx

Description: In the Linux kernel, the following vulnerability has been resolved:x86/vmscape: Add conditional IBPB mitigationVMSCAPE is a vulnerability that exploits insufficient branch predictorisolation between a guest and a userspace hypervisor (like QEMU). Existingmitigations already protect kernel/KVM from a malicious guest. Userspacecan additionally be protected by flushing the branch predictors after aVMexit.Since it is the userspace that consumes the poisoned branch predictors,conditionally issue an IBPB after a VMexit and before returning touserspace. Workloads that frequently switch between hypervisor anduserspace will incur the most overhead from the new IBPB.This new IBPB is not integrated with the existing IBPB sites. Forinstance, a task can use the existing speculation control prctl() toget an IBPB at context switch time. With this implementation, theIBPB is doubled up: one at context switch and another before runninguserspace.The intent is to integrate and optimize these cases post-embargo.[ dhansen: elaborate on suboptimal IBPB solution ]

CVE-2025-71104 Severity: Moderate CVSS3 score: 6.5

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: x86: Fix VM hard lockup after prolonged inactivity with periodic HV timerWhen advancing the target expiration for the guest's APIC timer in periodicmode, set the expiration to "now" if the target expiration is in the past(similar to what is done in update_target_expiration()). Blindly addingthe period to the previous target expiration can result in KVM generatinga practically unbounded number of hrtimer IRQs due to programming anexpired timer over and over. In extreme scenarios, e.g. if userspacepauses/suspends a VM for an extended duration, this can even cause hardlockups in the host.Currently, the bug only affects Intel CPUs when using the hypervisor timer(HV timer), a.k.a. the VMX preemption timer. Unlike the software timer,a.k.a. hrtimer, which KVM keeps running even on exits to userspace, theHV timer only runs while the guest is active. As a result, if the vCPUdoes not run for an extended duration, there will be a huge gap betweenthe target expiration and the current time the vCPU resumes running.Because the target expiration is incremented by only one period on eachtimer expiration, this leads to a series of timer expirations occurringrapidly after the vCPU/VM resumes.More critically, when the vCPU first triggers a periodic HV timerexpiration after resuming, advancing the expiration by only one periodwill result in a target expiration in the past. As a result, the deltamay be calculated as a negative value. When the delta is converted intoan absolute value (tscdeadline is an unsigned u64), the resulting valuecan overflow what the HV timer is capable of programming. I.e. the largevalue will exceed the VMX Preemption Timer's maximum bit width ofcpu_preemption_timer_multi + 32, and thus cause KVM to switch from theHV timer to the software timer (hrtimers).After switching to the software timer, periodic timer expiration callbacksmay be executed consecutively within a single clock interrupt handler,because hrtimers honors KVM's request for an expiration in the past andimmediately re-invokes KVM's callback after reprogramming. And becausethe interrupt handler runs with IRQs disabled, restarting KVM's hrtimerover and over until the target expiration is advanced to "now" can resultin a hard lockup.E.g. the following hard lockup was triggered in the host when running aWindows VM (only relevant because it used the APIC timer in periodic mode)after resuming the VM from a long suspend (in the host).

Since the periodic timer does not require frequent APICtimer register programming, the guest may continue to use the softwaretimer in ---truncated---

CVE-2026-23086 Severity: Moderate CVSS3 score: 6.5

Description: In the Linux kernel, the following vulnerability has been resolved:vsock/virtio: cap TX credit to local buffer sizeThe virtio transports derives its TX credit directly from peer_buf_alloc,which is set from the remote endpoint's SO_VM_SOCKETS_BUFFER_SIZE value.On the host side this means that the amount of data we are willing toqueue for a connection is scaled by a guest-chosen buffer size, ratherthan the host's own vsock configuration. A malicious guest can advertisea large buffer and read slowly, causing the host to allocate acorrespondingly large amount of sk_buff memory.The same thing would happen in the guest with a malicious host, sincevirtio transports share the same code base.Introduce a small helper, virtio_transport_tx_buf_size(), thatreturns min(peer_buf_alloc, buf_alloc), and use it wherever we consumepeer_buf_alloc.This ensures the effective TX window is bounded by both the peer'sadvertised buffer and our own buf_alloc (already clamped tobuffer_max_size via SO_VM_SOCKETS_BUFFER_MAX_SIZE), so a remote peercannot force the other to queue more data than allowed by its ownvsock settings.On an unpatched Ubuntu 22.04 host (~64 GiB RAM), running a PoC with32 guest vsock connections advertising 2 GiB each and reading slowlydrove Slab/SUnreclaim from ~0.5 GiB to ~57 GiB; the system onlyrecovered after killing the QEMU process. That said, if QEMU memory islimited with cgroups, the maximum memory used will be limited.With this patch applied: Before: MemFree: ~61.6 GiB Slab: ~142 MiB SUnreclaim: ~117 MiB After 32 high-credit connections: MemFree: ~61.5 GiB Slab: ~178 MiB SUnreclaim: ~152 MiBOnly ~35 MiB increase in Slab/SUnreclaim, no host OOM, and the guestremains responsive.Compatibility with non-virtio transports: - VMCI uses the AF_VSOCK buffer knobs to size its queue pairs per socket based on the local vsk->buffer_* values; the remote side cannot enlarge those queues beyond what the local endpoint configured. - Hyper-V's vsock transport uses fixed-size VMBus ring buffers and an MTU bound; there is no peer-controlled credit field comparable to peer_buf_alloc, and the remote endpoint cannot drive in-flight kernel memory above those ring sizes. - The loopback path reuses virtio_transport_common.c, so it naturally follows the same semantics as the virtio transport.This change is limited to virtio_transport_common.c and thus affectsvirtio-vsock, vhost-vsock, and loopback, bringing them in line with the"remote window intersected with local policy" behaviour that VMCI andHyper-V already effectively have.[Stefano: small adjustments after changing the previous patch][Stefano: tweak the commit message]

Description: In the Linux kernel, the following vulnerability has been resolved:net: add xmit recursion limit to tunnel xmit functionsTunnel xmit functions (iptunnel_xmit, ip6tunnel_xmit) lack their ownrecursion limit. When a bond device in broadcast mode has GRE tapinterfaces as slaves, and those GRE tunnels route back through thebond, multicast/broadcast traffic triggers infinite recursion betweenbond_xmit_broadcast() and ip_tunnel_xmit()/ip6_tnl_xmit(), causingkernel stack overflow.The existing XMIT_RECURSION_LIMIT (8) in the no-qdisc path is notsufficient because tunnel recursion involves route lookups and full IPoutput, consuming much more stack per level. Use a lower limit of 4(IP_TUNNEL_RECURSION_LIMIT) to prevent overflow.Add recursion detection using dev_xmit_recursion helpers directly iniptunnel_xmit() and ip6tunnel_xmit() to cover all IPv4/IPv6 tunnelpaths including UDP encapsulated tunnels (VXLAN, Geneve, etc.).Move dev_xmit_recursion helpers from net/core/dev.h to public headerinclude/linux/netdevice.h so they can be used by tunnel code.

It does not verify thepresence of the Mesh Channel Switch Parameters IE (element ID 118).When a received CSA action frame omits that IE, ieee802_11_parse_elems()leaves elems->mesh_chansw_params_ie as NULL, and the unconditionaldereference causes a kernel NULL pointer dereference.A remote mesh peer with an established peer link (PLINK_ESTAB) cantrigger this by sending a crafted SPECTRUM_MGMT/CHL_SWITCH action framethat includes a matching Mesh ID and Mesh Configuration IE but omits theMesh Channel Switch Parameters IE. No authentication beyond the defaultopen mesh peering is required.Crash confirmed on kernel 6.17.0-5-generic via mac80211_hwsim: BUG: kernel NULL pointer dereference, address: 0000000000000000 Oops: Oops: 0000 [#1] SMP NOPTI RIP: 0010:ieee80211_mesh_rx_queued_mgmt+0x143/0x2a0 [mac80211] CR2: 0000000000000000Fix by adding a NULL check for mesh_chansw_params_ie aftermesh_matches_local() returns, consistent with how other optional IEsare guarded throughout the mesh code.The bug has been present since v3.13 (released 2014-01-19).

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: mac80211: fix NULL deref in mesh_matches_local()mesh_matches_local() unconditionally dereferences ie->mesh_config tocompare mesh configuration parameters. When called frommesh_rx_csa_frame(), the parsed action-frame elements may not contain aMesh Configuration IE, leaving ie->mesh_config NULL and triggering akernel NULL pointer dereference.The other two callers are already safe: - ieee80211_mesh_rx_bcn_presp() checks !elems->mesh_config before calling mesh_matches_local() - mesh_plink_get_event() is only reached through mesh_process_plink_frame(), which checks !elems->mesh_config, toomesh_rx_csa_frame() is the only caller that passes raw parsed elementsto mesh_matches_local() without guarding mesh_config.

CVE-2026-28387 Severity: Moderate CVSS3 score: 6.5

Description: Issue summary: An uncommon configuration of clients performing DANE TLSA-basedserver authentication, when paired with uncommon server DANE TLSA records, mayresult in a use-after-free and/or double-free on the client side.Impact summary: A use after free can have a range of potential consequencessuch as the corruption of valid data, crashes or execution of arbitrary code.However, the issue only affects clients that make use of TLSA records with boththe PKIX-TA(0/PKIX-EE(1) certificate usages and the DANE-TA(2) certificateusage.By far the most common deployment of DANE is in SMTP MTAs for which RFC7672recommends that clients treat as 'unusable' any TLSA records that have the PKIXcertificate usages. These SMTP (or other similar) clients are not vulnerableto this issue. Conversely, any clients that support only the PKIX usages, andignore the DANE-TA(2) usage are also not vulnerable.The client would also need to be communicating with a server that publishes aTLSA RRset with both types of TLSA records.No FIPS modules are affected by this issue, the problem code is outside theFIPS module boundary.

CVE-2026-31790 Severity: Moderate CVSS3 score: 6.5

Description: Issue summary: Applications using RSASVE key encapsulation to establisha secret encryption key can send contents of an uninitialized memory buffer toa malicious peer.Impact summary: The uninitialized buffer might contain sensitive data from theprevious execution of the application process which leads to sensitive dataleakage to an attacker.RSA_public_encrypt() returns the number of bytes written on success and -1on error. The affected code tests only whether the return value is non-zero.As a result, if RSA encryption fails, encapsulation can still return success tothe caller, set the output lengths, and leave the caller to use the contents ofthe ciphertext buffer as if a valid KEM ciphertext had been produced.If applications use EVP_PKEY_encapsulate() with RSA/RSASVE on anattacker-supplied invalid RSA public key without first validating that key,then this may cause stale or uninitialized contents of the caller-providedciphertext buffer to be disclosed to the attacker in place of the KEMciphertext.As a workaround calling EVP_PKEY_public_check() orEVP_PKEY_public_check_quick() before EVP_PKEY_encapsulate() will mitigatethe issue.The FIPS modules in 3.6, 3.5, 3.4, 3.3, 3.1 and 3.0 are affected by this issue.

CVE-2026-3497 Severity: Moderate CVSS3 score: 6.5

Description: Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerability affects the GSSAPI patches added by various Linux distributions and does not affect the OpenSSH upstream project itself. The usage of sshpkt_disconnect() on an error, which does not terminate the process, allows an attacker to send an unexpected GSSAPI message type during the GSSAPI key exchange to the server, which will call the underlying function and continue the execution of the program without setting the related connection variables. As the variables are not initialized to NULL the code later accesses those uninitialized variables, accessing random memory, which could lead to undefined behavior. The recommended workaround is to use ssh_packet_disconnect() instead, which does terminate the process. The impact of the vulnerability depends heavily on the compiler flag hardening configuration.

CVE-2026-35469 Severity: Moderate CVSS3 score: 6.5

Description: spdystream is a Go library for multiplexing streams over SPDY connections. In versions 0.5.0 and below, the SPDY/3 frame parser does not validate attacker-controlled counts and lengths before allocating memory. Three allocation paths are affected: the SETTINGS frame entry count, the header count in parseHeaderValueBlock, and individual header field sizes - all read as 32-bit integers and used directly as allocation sizes with no bounds checking. Because SPDY header blocks are zlib-compressed, a small on-the-wire payload can decompress into large attacker-controlled values. A remote peer that can send SPDY frames to a service using spdystream can exhaust process memory and cause an out-of-memory crash with a single crafted control frame. This issue has been fixed in version 0.5.1.

CVE-2024-40927 Severity: Moderate CVSS3 score: 6.4

Description: In the Linux kernel, the following vulnerability has been resolved:xhci: Handle TD clearing for multiple streams caseWhen multiple streams are in use, multiple TDs might be in flight whenan endpoint is stopped. We need to issue a Set TR Dequeue Pointer foreach, to ensure everything is reset properly and the caches cleared.Change the logic so that any N>1 TDs found active for different streamsare deferred until after the first one is processed, callingxhci_invalidate_cancelled_tds() again from xhci_handle_cmd_set_deq() toqueue another command until we are done with all of them. Also changethe error/"should never happen" paths to ensure we at least clear anyaffected TDs, even if we can't issue a command to clear the hardwarecache, and complain loudly with an xhci_warn() if this ever happens.This problem case dates back to commit e9df17eb1408 ("USB: xhci: Correctassumptions about number of rings per endpoint.") early on in the XHCIdriver's life, when stream support was first added.It was then identified but not fixed nor made into a warning in commit674f8438c121 ("xhci: split handling halted endpoints into two steps"),which added a FIXME comment for the problem case (without materiallychanging the behavior as far as I can tell, though the new logic madethe problem more obvious).Then later, in commit 94f339147fc3 ("xhci: Fix failure to give back somecached cancelled URBs."), it was acknowledged again.[Mathias: commit 94f339147fc3 ("xhci: Fix failure to give back some cachedcancelled URBs.") was a targeted regression fix to the previously mentionedpatch. Users reported issues with usb stuck after unmounting/disconnectingUAS devices. This rolled back the TD clearing of multiple streams to itsoriginal state.]Apparently the commit author was aware of the problem (yet still choseto submit it): It was still mentioned as a FIXME, an xhci_dbg() wasadded to log the problem condition, and the remaining issue was mentionedin the commit description. The choice of making the log type xhci_dbg()for what is, at this point, a completely unhandled and known brokencondition is puzzling and unfortunate, as it guarantees that no actualusers would see the log in production, thereby making it nighundebuggable (indeed, even if you turn on DEBUG, the message doesn'treally hint at there being a problem at all).It took me *months* of random xHC crashes to finally find a reliablerepro and be able to do a deep dive debug session, which could all havebeen avoided had this unhandled, broken condition been actually reportedwith a warning, as it should have been as a bug intentionally left inunfixed (never mind that it shouldn't have been left in at all).> Another fix to solve clearing the caches of all stream rings with> cancelled TDs is needed, but not as urgent.3 years after that statement and 14 years after the original bug wasintroduced, I think it's finally time to fix it. And maybe next timelet's not leave bugs unfixed (that are actually worse than the originalbug), and let's actually get people to review kernel commits please.Fixes xHC crashes and IOMMU faults with UAS devices when handlingerrors/faults. Easiest repro is to use `hdparm` to mark an early sector(e.g. 1024) on a disk as bad, then `cat /dev/sdX > /dev/null` in a loop.At least in the case of JMicron controllers, the read errors end uphaving to cancel two TDs (for two queued requests to different streams)and the one that didn't get cleared properly ends up faulting the xHCentirely when it tries to access DMA pages that have since been unmapped,referred to by the stale TDs. This normally happens quickly (after twoor three loops). After this fix, I left the `cat` in a loop runningovernight and experienced no xHC failures, with all read errorsrecovered properly. Repro'd and tested on an Apple M1 Mac Mini(dwc3 host).On systems without an IOMMU, this bug would instead silently corruptfreed memory, making this a---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:loop: Avoid updating block size under exclusive ownerSyzbot came up with a reproducer where a loop device block size ischanged underneath a mounted filesystem. This causes a mismatch betweenthe block device block size and the block size stored in the superblockcausing confusion in various places such as fs/buffer.c. The particularissue triggered by syzbot was a warning in __getblk_slow() due torequested buffer size not matching block device block size.Fix the problem by getting exclusive hold of the loop device to changeits block size. This fails if somebody (such as filesystem) has alreadyan exclusive ownership of the block device and thus prevents modifyingthe loop device under some exclusive owner which doesn't expect it.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: qgroup: fix race between quota disable and quota rescan ioctlThere's a race between a task disabling quotas and another running therescan ioctl that can result in a use-after-free of qgroup records fromthe fs_info->qgroup_tree rbtree.This happens as follows:1) Task A enters btrfs_ioctl_quota_rescan() -> btrfs_qgroup_rescan();2) Task B enters btrfs_quota_disable() and calls btrfs_qgroup_wait_for_completion(), which does nothing because at that point fs_info->qgroup_rescan_running is false (it wasn't set yet by task A);3) Task B calls btrfs_free_qgroup_config() which starts freeing qgroups from fs_info->qgroup_tree without taking the lock fs_info->qgroup_lock;4) Task A enters qgroup_rescan_zero_tracking() which starts iterating the fs_info->qgroup_tree tree while holding fs_info->qgroup_lock, but task B is freeing qgroup records from that tree without holding the lock, resulting in a use-after-free.Fix this by taking fs_info->qgroup_lock at btrfs_free_qgroup_config().Also at btrfs_qgroup_rescan() don't start the rescan worker if quotaswere already disabled.

This leadsto UAF issues during subsequent accesses. Here's an example of reproductionsteps:1. With /dev/fb0 already registered in the system, load a kernel module to register a new device /dev/fb1;2. Set fb1's mode to the global fb_display[] array (via FBIOPUT_CON2FBMAP);3. Switch console from fb to VGA (to allow normal rmmod of the ko);4. Unload the kernel module, at this point fb1's modelist is freed, leaving a wild pointer in fb_display[];5. Trigger the bug via system calls through fb0 attempting to delete a mode from fb0.Add a check in do_unregister_framebuffer(): if the mode to be freed existsin fb_display[], set the corresponding mode pointer to NULL.

Description: In the Linux kernel, the following vulnerability has been resolved:net: sched: avoid qdisc_reset_all_tx_gt() vs dequeue race for lockless qdiscsWhen shrinking the number of real tx queues,netif_set_real_num_tx_queues() calls qdisc_reset_all_tx_gt() to flushqdiscs for queues which will no longer be used.qdisc_reset_all_tx_gt() currently serializes qdisc_reset() withqdisc_lock(). However, for lockless qdiscs, the dequeue path isserialized by qdisc_run_begin/end() using qdisc->seqlock instead, soqdisc_reset() can run concurrently with __qdisc_run() and free skbswhile they are still being dequeued, leading to UAF.This can easily be reproduced on e.g. virtio-net by imposing heavytraffic while frequently changing the number of queue pairs: iperf3 -ub0 -c $peer -t 0 & while :; do ethtool -L eth0 combined 1 ethtool -L eth0 combined 2 doneWith KASAN enabled, this leads to reports like: BUG: KASAN: slab-use-after-free in __qdisc_run+0x133f/0x1760 ...

CVE-2026-23454 Severity: Moderate CVSS3 score: 6.4

Description: In the Linux kernel, the following vulnerability has been resolved:net: mana: fix use-after-free in mana_hwc_destroy_channel() by reordering teardownA potential race condition exists in mana_hwc_destroy_channel() wherehwc->caller_ctx is freed before the HWC's Completion Queue (CQ) andEvent Queue (EQ) are destroyed. This allows an in-flight CQ interrupthandler to dereference freed memory, leading to a use-after-free orNULL pointer dereference in mana_hwc_handle_resp().mana_smc_teardown_hwc() signals the hardware to stop but does notsynchronize against IRQ handlers already executing on other CPUs. TheIRQ synchronization only happens in mana_hwc_destroy_cq() viamana_gd_destroy_eq() -> mana_gd_deregister_irq(). Since this runsafter kfree(hwc->caller_ctx), a concurrent mana_hwc_rx_event_handler()can dereference freed caller_ctx (and rxq->msg_buf) inmana_hwc_handle_resp().Fix this by reordering teardown to reverse-of-creation order: destroythe TX/RX work queues and CQ/EQ before freeing hwc->caller_ctx. Thisensures all in-flight interrupt handlers complete before the memory theyaccess is freed.

Description: In the Linux kernel, the following vulnerability has been resolved:net: bonding: fix use-after-free in bond_xmit_broadcast()bond_xmit_broadcast() reuses the original skb for the last slave(determined by bond_is_last_slave()) and clones it for others.Concurrent slave enslave/release can mutate the slave list duringRCU-protected iteration, changing which slave is "last" mid-loop.This causes the original skb to be double-consumed (double-freed).Replace the racy bond_is_last_slave() check with a simple indexcomparison (i + 1 == slaves_count) against the pre-snapshot slavecount taken via READ_ONCE() before the loop. This preserves thezero-copy optimization for the last slave while making the "last"determination stable against concurrent list mutations.The UAF can trigger the following crash:==================================================================BUG: KASAN: slab-use-after-free in skb_cloneRead of size 8 at addr ffff888100ef8d40 by task exploit/147CPU: 1 UID: 0 PID: 147 Comm: exploit Not tainted 7.0.0-rc3+ #4 PREEMPTLAZYCall Trace: dump_stack_lvl (lib/dump_stack.c:123) print_report (mm/kasan/report.c:379 mm/kasan/report.c:482) kasan_report (mm/kasan/report.c:597) skb_clone (include/linux/skbuff.h:1724 include/linux/skbuff.h:1792 include/linux/skbuff.h:3396 net/core/skbuff.c:2108) bond_xmit_broadcast (drivers/net/bonding/bond_main.c:5334) bond_start_xmit (drivers/net/bonding/bond_main.c:5567 drivers/net/bonding/bond_main.c:5593) dev_hard_start_xmit (include/linux/netdevice.h:5325 include/linux/netdevice.h:5334 net/core/dev.c:3871 net/core/dev.c:3887) __dev_queue_xmit (include/linux/netdevice.h:3601 net/core/dev.c:4838) ip6_finish_output2 (include/net/neighbour.h:540 include/net/neighbour.h:554 net/ipv6/ip6_output.c:136) ip6_finish_output (net/ipv6/ip6_output.c:208 net/ipv6/ip6_output.c:219) ip6_output (net/ipv6/ip6_output.c:250) ip6_send_skb (net/ipv6/ip6_output.c:1985) udp_v6_send_skb (net/ipv6/udp.c:1442) udpv6_sendmsg (net/ipv6/udp.c:1733) __sys_sendto (net/socket.c:730 net/socket.c:742 net/socket.c:2206) __x64_sys_sendto (net/socket.c:2209) do_syscall_64 (arch/x86/entry/syscall_64.c:63 arch/x86/entry/syscall_64.c:94) entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:130) Allocated by task 147:Freed by task 147:The buggy address belongs to the object at ffff888100ef8c80 which belongs to the cache skbuff_head_cache of size 224The buggy address is located 192 bytes inside of freed 224-byte region [ffff888100ef8c80, ffff888100ef8d60)Memory state around the buggy address: ffff888100ef8c00: fb fb fb fb fc fc fc fc fc fc fc fc fc fc fc fc ffff888100ef8c80: fa fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb>ffff888100ef8d00: fb fb fb fb fb fb fb fb fb fb fb fb fc fc fc fc ^ ffff888100ef8d80: fc fc fc fc fc fc fc fc fa fb fb fb fb fb fb fb ffff888100ef8e00: fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb fb==================================================================

However, inode<5> contain incorrect imode anddisordered extents, and i_nlink is set to 1. The extents check for inode inthe ext4_iget function can be bypassed bacause 5 is EXT4_BOOT_LOADER_INO.While links_count is set to 1, the extents are not initialized inswap_inode_boot_loader. After the ioctl command is executed successfully,the extents are swapped to inode<12>, in this case, run the `cat` commandto view inode<12>. And Bug_ON is triggered due to the incorrect extents.When the boot loader inode is not initialized, its imode can be one of thefollowing:1) the imode is a bad type, which is marked as bad_inode in ext4_iget and set to S_IFREG.2) the imode is good type but not S_IFREG.3) the imode is S_IFREG.The BUG_ON may be triggered by bypassing the check in cases 1 and 2.Therefore, when the boot loader inode is bad_inode or its imode is notS_IFREG, initialize the inode to avoid triggering the BUG.

CVE-2022-50720 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:x86/apic: Don't disable x2APIC if lockedThe APIC supports two modes, legacy APIC (or xAPIC), and Extended APIC(or x2APIC). X2APIC mode is mostly compatible with legacy APIC, butit disables the memory-mapped APIC interface in favor of one that usesMSRs. The APIC mode is controlled by the EXT bit in the APIC MSR.The MMIO/xAPIC interface has some problems, most notably the APIC LEAK[1]. This bug allows an attacker to use the APIC MMIO interface toextract data from the SGX enclave.Introduce support for a new feature that will allow the BIOS to lockthe APIC in x2APIC mode. If the APIC is locked in x2APIC mode and thekernel tries to disable the APIC or revert to legacy APIC mode a GPfault will occur.Introduce support for a new MSR (IA32_XAPIC_DISABLE_STATUS) and handlethe new locked mode when the LEGACY_XAPIC_DISABLED bit is set bypreventing the kernel from trying to disable the x2APIC.On platforms with the IA32_XAPIC_DISABLE_STATUS MSR, if SGX or TDX areenabled the LEGACY_XAPIC_DISABLED will be set by the BIOS. Iflegacy APIC is required, then it SGX and TDX need to be disabled in theBIOS.[1]: https://aepicleak.com/aepicleak.pdf

CVE-2023-53623 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:mm/swap: fix swap_info_struct race between swapoff and get_swap_pages()The si->lock must be held when deleting the si from the available list. Otherwise, another thread can re-add the si to the available list, whichcan lead to memory corruption. The only place we have found where thishappens is in the swapoff path. This case can be described as below:core 0 core 1swapoffdel_from_avail_list(si) waitingtry lock si->lock acquire swap_avail_lock and re-add si into swap_avail_headacquire si->lock but missing si already being added again, and continuingto clear SWP_WRITEOK, etc.It can be easily found that a massive warning messages can be triggeredinside get_swap_pages() by some special cases, for example, we callmadvise(MADV_PAGEOUT) on blocks of touched memory concurrently, meanwhile,run much swapon-swapoff operations (e.g. stress-ng-swap).However, in the worst case, panic can be caused by the above scene. Inswapoff(), the memory used by si could be kept in swap_info[] afterturning off a swap. This means memory corruption will not be causedimmediately until allocated and reset for a new swap in the swapon path.

CVE-2023-54096 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:soundwire: fix enumeration completionThe soundwire subsystem uses two completion structures that allowdrivers to wait for soundwire device to become enumerated on the bus andinitialised by their drivers, respectively.The code implementing the signalling is currently broken as it does notsignal all current and future waiters and also uses the wrongreinitialisation function, which can potentially lead to memorycorruption if there are still waiters on the queue.Not signalling future waiters specifically breaks sound card probedeferrals as codec drivers can not tell that the soundwire device isalready attached when being reprobed. Some codec runtime PMimplementations suffer from similar problems as waiting for enumerationduring resume can also timeout despite the device already having beenenumerated.

Description: In the Linux kernel, the following vulnerability has been resolved:vfio/type1: fix cap_migration information leakFix an information leak where an uninitialized hole in structvfio_iommu_type1_info_cap_migration on the stack is exposed to userspace.The definition of struct vfio_iommu_type1_info_cap_migration contains a hole asshown in this pahole(1) output: struct vfio_iommu_type1_info_cap_migration { struct vfio_info_cap_header header; /* 0 8 */ __u32 flags; /* 8 4 */ /* XXX 4 bytes hole, try to pack */ __u64 pgsize_bitmap; /* 16 8 */ __u64 max_dirty_bitmap_size; /* 24 8 */ /* size: 32, cachelines: 1, members: 4 */ /* sum members: 28, holes: 1, sum holes: 4 */ /* last cacheline: 32 bytes */ };The cap_mig variable is filled in without initializing the hole: static int vfio_iommu_migration_build_caps(struct vfio_iommu *iommu, struct vfio_info_cap *caps) { struct vfio_iommu_type1_info_cap_migration cap_mig; cap_mig.header.id = VFIO_IOMMU_TYPE1_INFO_CAP_MIGRATION; cap_mig.header.version = 1; cap_mig.flags = 0; /* support minimum pgsize */ cap_mig.pgsize_bitmap = (size_t)1 << __ffs(iommu->pgsize_bitmap); cap_mig.max_dirty_bitmap_size = DIRTY_BITMAP_SIZE_MAX; return vfio_info_add_capability(caps, &cap_mig.header, sizeof(cap_mig)); }The structure is then copied to a temporary location on the heap.

CVE-2023-54269 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:SUNRPC: double free xprt_ctxt while still in useWhen an RPC request is deferred, the rq_xprt_ctxt pointer is moved outof the svc_rqst into the svc_deferred_req.When the deferred request is revisited, the pointer is copied intothe new svc_rqst - and also remains in the svc_deferred_req.In the (rare?) case that the request is deferred a second time, the oldsvc_deferred_req is reused - it still has all the correct content.However in that case the rq_xprt_ctxt pointer is NOT cleared so thatwhen xpo_release_xprt is called, the ctxt is freed (UDP) or possibleadded to a free list (RDMA).When the deferred request is revisited for a second time, it willreference this ctxt which may be invalid, and the free the object asecond time which is likely to oops.So change svc_defer() to *always* clear rq_xprt_ctxt, and assert thatthe value is now stored in the svc_deferred_req.

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: qat - fix out-of-bounds readWhen preparing an AER-CTR request, the driver copies the key provided bythe user into a data structure that is accessible by the firmware.If the target device is QAT GEN4, the key size is rounded up by 16 sincea rounded up size is expected by the device.If the key size is rounded up before the copy, the size used for copyingthe key might be bigger than the size of the region containing the key,causing an out-of-bounds read.Fix by doing the copy first and then update the keylen.This is to fix the following warning reported by KASAN: [ 138.150574] BUG: KASAN: global-out-of-bounds in qat_alg_skcipher_init_com.isra.0+0x197/0x250 [intel_qat] [ 138.150641] Read of size 32 at addr ffffffff88c402c0 by task cryptomgr_test/2340 [ 138.150651] CPU: 15 PID: 2340 Comm: cryptomgr_test Not tainted 6.2.0-rc1+ #45 [ 138.150659] Hardware name: Intel Corporation ArcherCity/ArcherCity, BIOS EGSDCRB1.86B.0087.D13.2208261706 08/26/2022 [ 138.150663] Call Trace: [ 138.150668] [ 138.150922] kasan_check_range+0x13a/0x1c0 [ 138.150931] memcpy+0x1f/0x60 [ 138.150940] qat_alg_skcipher_init_com.isra.0+0x197/0x250 [intel_qat] [ 138.151006] qat_alg_skcipher_init_sessions+0xc1/0x240 [intel_qat] [ 138.151073] crypto_skcipher_setkey+0x82/0x160 [ 138.151085] ? prepare_keybuf+0xa2/0xd0 [ 138.151095] test_skcipher_vec_cfg+0x2b8/0x800

Description: In the Linux kernel, the following vulnerability has been resolved:enic: Validate length of nl attributes in enic_set_vf_portenic_set_vf_port assumes that the nl attribute IFLA_PORT_PROFILEis of length PORT_PROFILE_MAX and that the nl attributesIFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID are of length PORT_UUID_MAX.These attributes are validated (in the function do_setlink in rtnetlink.c)using the nla_policy ifla_port_policy. The policy defines IFLA_PORT_PROFILEas NLA_STRING, IFLA_PORT_INSTANCE_UUID as NLA_BINARY andIFLA_PORT_HOST_UUID as NLA_STRING. That means that the length validationusing the policy is for the max size of the attributes and not on exactsize so the length of these attributes might be less than the sizes thatenic_set_vf_port expects. This might cause an out of bandsread access in the memcpys of the data of theseattributes in enic_set_vf_port.

To mitigate this, refactorthe code to use atomic operations such as set_bit(), test_bit(), andclear_bit() instead of basic "and" and "or" operations. This ensuresthread-safe manipulation of worker flags.Also, move `create_index` to avoid holes in the structure.

CVE-2024-50063 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Prevent tail call between progs attached to different hooksbpf progs can be attached to kernel functions, and the attached functionscan take different parameters or return different return values. Ifprog attached to one kernel function tail calls prog attached to anotherkernel function, the ctx access or return value verification could bebypassed.For example, if prog1 is attached to func1 which takes only 1 parameterand prog2 is attached to func2 which takes two parameters. Since verifierassumes the bpf ctx passed to prog2 is constructed based on func2'sprototype, verifier allows prog2 to access the second parameter fromthe bpf ctx passed to it. The problem is that verifier does not preventprog1 from passing its bpf ctx to prog2 via tail call. In this case,the bpf ctx passed to prog2 is constructed from func1 instead of func2,that is, the assumption for ctx access verification is bypassed.Another example, if BPF LSM prog1 is attached to hook file_alloc_security,and BPF LSM prog2 is attached to hook bpf_lsm_audit_rule_known. Verifierknows the return value rules for these two hooks, e.g. it is legal forbpf_lsm_audit_rule_known to return positive number 1, and it is illegalfor file_alloc_security to return positive number. So verifier allowsprog2 to return positive number 1, but does not allow prog1 to returnpositive number. The problem is that verifier does not prevent prog1from calling prog2 via tail call. In this case, prog2's return value 1will be used as the return value for prog1's hook file_alloc_security.That is, the return value rule is bypassed.This patch adds restriction for tail call to prevent such bypasses.

CVE-2024-53088 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:i40e: fix race condition by adding filter's intermediate sync stateFix a race condition in the i40e driver that leads to MAC/VLAN filtersbecoming corrupted and leaking. Address the issue that occurs underheavy load when multiple threads are concurrently modifying MAC/VLANfilters by setting mac and port VLAN.1. Thread T0 allocates a filter in i40e_add_filter() within i40e_ndo_set_vf_port_vlan().2. Thread T1 concurrently frees the filter in __i40e_del_filter() within i40e_ndo_set_vf_mac().3. Subsequently, i40e_service_task() calls i40e_sync_vsi_filters(), which refers to the already freed filter memory, causing corruption.Reproduction steps:1. Spawn multiple VFs.2. Apply a concurrent heavy load by running parallel operations to change MAC addresses on the VFs and change port VLANs on the host.3. Observe errors in dmesg:"Error I40E_AQ_RC_ENOSPC adding RX filters on VF XX, please set promiscuous on manually for VF XX".Exact code for stable reproduction Intel can't open-source now.The fix involves implementing a new intermediate filter state,I40E_FILTER_NEW_SYNC, for the time when a filter is on a tmp_add_list.These filters cannot be deleted from the hash list directly butmust be removed using the full process.

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: Avoid race in open_cached_dir with lease breaksA pre-existing valid cfid returned from find_or_create_cached_dir mightrace with a lease break, meaning open_cached_dir doesn't consider itvalid, and thinks it's newly-constructed. This leaks a dentry referenceif the allocation occurs before the queued lease break work runs.Avoid the race by extending holding the cfid_list_lock acrossfind_or_create_cached_dir and when the result is checked.

Description: In the Linux kernel, the following vulnerability has been resolved:virtio: break and reset virtio devices on device_shutdown()Hongyu reported a hang on kexec in a VM. QEMU reported invalid memoryaccesses during the hang. Invalid read at addr 0x102877002, size 2, region '(null)', reason: rejected Invalid write at addr 0x102877A44, size 2, region '(null)', reason: rejected ...It was traced down to virtio-console. Kexec works fine if virtio-consoleis not in use.The issue is that virtio-console continues to write to the MMIO even afterunderlying virtio-pci device is reset.Additionally, Eric noticed that IOMMUs are reset before devices, ifdevices are not reset on shutdown they continue to poke at guest memoryand get errors from the IOMMU. Some devices get wedged then.The problem can be solved by breaking all virtio devices on virtiobus shutdown, then resetting them.

CVE-2025-38365 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix a race between renames and directory loggingWe have a race between a rename and directory inode logging that if ithappens and we crash/power fail before the rename completes, the next timethe filesystem is mounted, the log replay code will end up deleting thefile that was being renamed.This is best explained following a step by step analysis of an interleavingof steps that lead into this situation.Consider the initial conditions:1) We are at transaction N;2) We have directories A and B created in a past transaction (< N);3) We have inode X corresponding to a file that has 2 hardlinks, one in directory A and the other in directory B, so we'll name them as "A/foo_link1" and "B/foo_link2". Both hard links were persisted in a past transaction (< N);4) We have inode Y corresponding to a file that as a single hard link and is located in directory A, we'll name it as "A/bar". This file was also persisted in a past transaction (< N).The steps leading to a file loss are the following and for all of them weare under transaction N: 1) Link "A/foo_link1" is removed, so inode's X last_unlink_trans field is updated to N, through btrfs_unlink() -> btrfs_record_unlink_dir(); 2) Task A starts a rename for inode Y, with the goal of renaming from "A/bar" to "A/baz", so we enter btrfs_rename(); 3) Task A inserts the new BTRFS_INODE_REF_KEY for inode Y by calling btrfs_insert_inode_ref(); 4) Because the rename happens in the same directory, we don't set the last_unlink_trans field of directoty A's inode to the current transaction id, that is, we don't cal btrfs_record_unlink_dir(); 5) Task A then removes the entries from directory A (BTRFS_DIR_ITEM_KEY and BTRFS_DIR_INDEX_KEY items) when calling __btrfs_unlink_inode() (actually the dir index item is added as a delayed item, but the effect is the same); 6) Now before task A adds the new entry "A/baz" to directory A by calling btrfs_add_link(), another task, task B is logging inode X; 7) Task B starts a fsync of inode X and after logging inode X, at btrfs_log_inode_parent() it calls btrfs_log_all_parents(), since inode X has a last_unlink_trans value of N, set at in step 1; 8) At btrfs_log_all_parents() we search for all parent directories of inode X using the commit root, so we find directories A and B and log them. Bu when logging direct A, we don't have a dir index item for inode Y anymore, neither the old name "A/bar" nor for the new name "A/baz" since the rename has deleted the old name but has not yet inserted the new name - task A hasn't called yet btrfs_add_link() to do that. Note that logging directory A doesn't fallback to a transaction commit because its last_unlink_trans has a lower value than the current transaction's id (see step 4); 9) Task B finishes logging directories A and B and gets back to btrfs_sync_file() where it calls btrfs_sync_log() to persist the log tree;10) Task B successfully persisted the log tree, btrfs_sync_log() completed with success, and a power failure happened. We have a log tree without any directory entry for inode Y, so the log replay code deletes the entry for inode Y, name "A/bar", from the subvolume tree since it doesn't exist in the log tree and the log tree is authorative for its index (we logged a BTRFS_DIR_LOG_INDEX_KEY item that covers the index range for the dentry that corresponds to "A/bar"). Since there's no other hard link for inode Y and the log replay code deletes the name "A/bar", the file is lost.The issue wouldn't happen if task B synced the log only after task Acalled btrfs_log_new_name(), which would update the log with the new namefor inode Y ("A/bar").Fix this by pinning the log root during renames before removing the olddirectory entry, and unpinning af---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:net: nfc: nci: Add parameter validation for packet dataSyzbot reported an uninitialized value bug in nci_init_req, which wasintroduced by commit 5aca7966d2a7 ("Merge tag'perf-tools-fixes-for-v6.17-2025-09-16' ofgit://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools").This bug arises due to very limited and poor input validationthat was done at nic_valid_size(). This validation onlyvalidates the skb->len (directly reflects size provided at theuserspace interface) with the length provided in the bufferitself (interpreted as NCI_HEADER). This leads to the processingof memory content at the address assuming the correct layoutper what opcode requires there. This leads to the accesses tobuffer of `skb_buff->data` which is not assigned anything yet.Following the same silent drop of packets of invalid sizes at`nic_valid_size()`, add validation of the data in the respectivehandlers and return error values in case of failure. Releasethe skb if error values are returned from handlers in`nci_nft_packet` and effectively do a silent dropPossible TODO: because we silently drop the packets, thecall to `nci_request` will be waiting for completion of requestand will face timeouts. These timeouts can get excessively loggedin the dmesg. A proper handling of them may require to export`nci_request_cancel` (or propagate error handling from thenft packets handlers).

CVE-2025-68264 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: refresh inline data size before write operationsThe cached ei->i_inline_size can become stale between the initial sizecheck and when ext4_update_inline_data()/ext4_create_inline_data() useit. Although ext4_get_max_inline_size() reads the correct value at thetime of the check, concurrent xattr operations can modify i_inline_sizebefore ext4_write_lock_xattr() is acquired.This causes ext4_update_inline_data() and ext4_create_inline_data() towork with stale capacity values, leading to a BUG_ON() crash inext4_write_inline_data(): kernel BUG at fs/ext4/inline.c:1331! BUG_ON(pos + len > EXT4_I(inode)->i_inline_size);The race window:1. ext4_get_max_inline_size() reads i_inline_size = 60 (correct)2. Size check passes for 50-byte write3. [Another thread adds xattr, i_inline_size changes to 40]4. ext4_write_lock_xattr() acquires lock5. ext4_update_inline_data() uses stale i_inline_size = 606. Attempts to write 50 bytes but only 40 bytes actually available7. BUG_ON() triggersFix this by recalculating i_inline_size via ext4_find_inline_data_nolock()immediately after acquiring xattr_sem. This ensures ext4_update_inline_data()and ext4_create_inline_data() work with current values that are protectedfrom concurrent modifications.This is similar to commit a54c4613dac1 ("ext4: fix race writing to aninline_data file while its xattrs are changing") which fixed i_inline_offstaleness. This patch addresses the related i_inline_size staleness issue.

CVE-2025-68794 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:iomap: adjust read range correctly for non-block-aligned positionsiomap_adjust_read_range() assumes that the position and length passed inare block-aligned. This is not always the case however, as shown in thesyzbot generated case for erofs. This causes too many bytes to beskipped for uptodate blocks, which results in returning the incorrectposition and length to read in. If all the blocks are uptodate, thisunderflows length and returns a position beyond the folio.Fix the calculation to also take into account the block offset whencalculating how many bytes can be skipped for uptodate blocks.

CVE-2025-71152 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:net: dsa: properly keep track of conduit referenceProblem description-------------------DSA has a mumbo-jumbo of reference handling of the conduit net deviceand its kobject which, sadly, is just wrong and doesn't make sense.There are two distinct problems.1. The OF path, which uses of_find_net_device_by_node(), never releases the elevated refcount on the conduit's kobject. Nominally, the OF and non-OF paths should result in objects having identical reference counts taken, and it is already suspicious that dsa_dev_to_net_device() has a put_device() call which is missing in dsa_port_parse_of(), but we can actually even verify that an issue exists. With CONFIG_DEBUG_KOBJECT_RELEASE=y, if we run this command "before" and "after" applying this patch:(unbind the conduit driver for net device eno2)echo 0000:00:00.2 > /sys/bus/pci/drivers/fsl_enetc/unbindwe see these lines in the output diff which appear only with the patchapplied:kobject: 'eno2' (ffff002009a3a6b8): kobject_release, parent 0000000000000000 (delayed 1000)kobject: '109' (ffff0020099d59a0): kobject_release, parent 0000000000000000 (delayed 1000)2. After we find the conduit interface one way (OF) or another (non-OF), it can get unregistered at any time, and DSA remains with a long-lived, but in this case stale, cpu_dp->conduit pointer. Holding the net device's underlying kobject isn't actually of much help, it just prevents it from being freed (but we never need that kobject directly). What helps us to prevent the net device from being unregistered is the parallel netdev reference mechanism (dev_hold() and dev_put()).Actually we actually use that netdev tracker mechanism implicitly onuser ports since commit 2f1e8ea726e9 ("net: dsa: link interfaces withthe DSA master to get rid of lockdep warnings"), via netdev_upper_dev_link().But time still passes at DSA switch probe time between the initialof_find_net_device_by_node() code and the user port creation time, timeduring which the conduit could unregister itself and DSA wouldn't knowabout it.So we have to run of_find_net_device_by_node() under rtnl_lock() toprevent that from happening, and release the lock only with the netdevtracker having acquired the reference.Do we need to keep the reference until dsa_unregister_switch() /dsa_switch_shutdown()?1: Maybe yes. A switch device will still be registered even if all user ports failed to probe, see commit 86f8b1c01a0a ("net: dsa: Do not make user port errors fatal"), and the cpu_dp->conduit pointers remain valid. I haven't audited all call paths to see whether they will actually use the conduit in lack of any user port, but if they do, it seems safer to not rely on user ports for that reference.2. Definitely yes. We support changing the conduit which a user port is associated to, and we can get into a situation where we've moved all user ports away from a conduit, thus no longer hold any reference to it via the net device tracker. But we shouldn't let it go nonetheless - see the next change in relation to dsa_tree_find_first_conduit() and LAG conduits which disappear. We have to be prepared to return to the physical conduit, so the CPU port must explicitly keep another reference to it. This is also to say: the user ports and their CPU ports may not always keep a reference to the same conduit net device, and both are needed.As for the conduit's kobject for the /sys/class/net/ entry, we don'tcare about it, we can release it as soon as we hold the net deviceobject itself.History and blame attribution-----------------------------The code has been refactored so many times, it is very difficult tofollow and properly attribute a blame, but I'll try to make a shorthistory which I hope to be correct.We have two distinct probing paths:- one for OF, introduced in 2016 i---truncated---

CVE-2026-23056 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:uacce: implement mremap in uacce_vm_ops to return -EPERMThe current uacce_vm_ops does not support the mremap operation ofvm_operations_struct. Implement .mremap to return -EPERM to remindusers.The reason we need to explicitly disable mremap is that when thedriver does not implement .mremap, it uses the default mremapmethod. This could lead to a risk scenario:An application might first mmap address p1, then mremap to p2,followed by munmap(p1), and finally munmap(p2). Since the defaultmremap copies the original vma's vm_private_data (i.e., q) to thenew vma, both munmap operations would trigger vma_close, causingq->qfr to be freed twice(qfr will be set to null here, so repeatedrelease is ok).

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: scarlett2: Fix buffer overflow in config retrievalThe scarlett2_usb_get_config() function has a logic error in theendianness conversion code that can cause buffer overflows whencount > 1.The code checks `if (size == 2)` where `size` is the total buffer size inbytes, then loops `count` times treating each element as u16 (2 bytes).This causes the loop to access `count * 2` bytes when the buffer onlyhas `size` bytes allocated.Fix by checking the element size (config_item->size) instead of thetotal buffer size. This ensures the endianness conversion matches theactual element type.

CVE-2026-23262 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:gve: Fix stats report corruption on queue count changeThe driver and the NIC share a region in memory for stats reporting.The NIC calculates its offset into this region based on the total sizeof the stats region and the size of the NIC's stats.When the number of queues is changed, the driver's stats region isresized. If the queue count is increased, the NIC can write pastthe end of the allocated stats region, causing memory corruption.If the queue count is decreased, there is a gap between the driverand NIC stats, leading to incorrect stats reporting.This change fixes the issue by allocating stats region with maximumsize, and the offset calculation for NIC stats is changed to matchwith the calculation of the NIC.

CVE-2026-23281 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: libertas: fix use-after-free in lbs_free_adapter()The lbs_free_adapter() function uses timer_delete() (non-synchronous)for both command_timer and tx_lockup_timer before the structure isfreed. This is incorrect because timer_delete() does not wait forany running timer callback to complete.If a timer callback is executing when lbs_free_adapter() is called,the callback will access freed memory since lbs_cfg_free() frees thecontaining structure immediately after lbs_free_adapter() returns.Both timer callbacks (lbs_cmd_timeout_handler and lbs_tx_lockup_handler)access priv->driver_lock, priv->cur_cmd, priv->dev, and other fields,which would all be use-after-free violations.Use timer_delete_sync() instead to ensure any running timer callbackhas completed before returning.This bug was introduced in commit 8f641d93c38a ("libertas: detect TXlockups and reset hardware") where del_timer() was used instead ofdel_timer_sync() in the cleanup path. The command_timer has had thesame issue since the driver was first written.

Description: In the Linux kernel, the following vulnerability has been resolved:drbd: fix "LOGIC BUG" in drbd_al_begin_io_nonblock()Even though we check that we "should" be able to do lc_get_cumulative()while holding the device->al_lock spinlock, it may still fail,if some other code path decided to do lc_try_lock() with bad timing.If that happened, we logged "LOGIC BUG for enr=...",but still did not return an error.The rest of the code now assumed that this request has referencesfor the relevant activity log extents.The implcations are that during an active resync, mutual exclusivity ofresync versus application IO is not guaranteed. And a potential crashat this point may not realizs that these extents could have been targetof in-flight IO and would need to be resynced just in case.Also, once the request completes, it will give up activity log references itdoes not even hold, which will trigger a BUG_ON(refcnt == 0) in lc_put().Fix:Do not crash the kernel for a condition that is harmless during normaloperation: also catch "e->refcnt == 0", not only "e == NULL"when being noisy about "al_complete_io() called on inactive extent %u\n".And do not try to be smart and "guess" whether something will work, thenbe surprised when it does not.Deal with the fact that it may or may not work. If it does not, remember apossible "partially in activity log" state (only possible for requests thatcross extent boundaries), and return an error code fromdrbd_al_begin_io_nonblock().A latter call for the same request will then resume from where we left off.

Description: In the Linux kernel, the following vulnerability has been resolved:lib: cpu_rmap: Avoid use after free on rmap->obj array entriesWhen calling irq_set_affinity_notifier() with NULL at the notifyargument, it will cause freeing of the glue pointer in thecorresponding array entry but will leave the pointer in the array. Asubsequent call to free_irq_cpu_rmap() will try to free this entry againleading to possible use after free.Fix that by setting NULL to the array entry and checking that we havenon-zero at the array entry when iterating over the array infree_irq_cpu_rmap().The current code does not suffer from this since there are no caseswhere irq_set_affinity_notifier(irq, NULL) (note the NULL passed for thenotify arg) is called, followed by a call to free_irq_cpu_rmap() so wedon't hit and issue. Subsequent patches in this series excersize thisflow, hence the required fix.

CVE-2025-68160 Severity: Moderate CVSS3 score: 6.2

Description: Issue summary: Writing large, newline-free data into a BIO chain using theline-buffering filter where the next BIO performs short writes can triggera heap-based out-of-bounds write.Impact summary: This out-of-bounds write can cause memory corruption whichtypically results in a crash, leading to Denial of Service for an application.The line-buffering BIO filter (BIO_f_linebuffer) is not used by default inTLS/SSL data paths. In OpenSSL command-line applications, it is typicallyonly pushed onto stdout/stderr on VMS systems. Third-party applications thatexplicitly use this filter with a BIO chain that can short-write and thatwrite large, newline-free data influenced by an attacker would be affected.However, the circumstances where this could happen are unlikely to be underattacker control, and BIO_f_linebuffer is unlikely to be handling non-curateddata controlled by an attacker. For that reason the issue was assessed asLow severity.The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,as the BIO implementation is outside the OpenSSL FIPS module boundary.OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0, 1.1.1 and 1.0.2 are vulnerable to this issue.

CVE-2025-69419 Severity: Moderate CVSS3 score: 6.2

Description: Issue summary: Calling PKCS12_get_friendlyname() function on a maliciouslycrafted PKCS#12 file with a BMPString (UTF-16BE) friendly name containingnon-ASCII BMP code point can trigger a one byte write before the allocatedbuffer.Impact summary: The out-of-bounds write can cause a memory corruptionwhich can have various consequences including a Denial of Service.The OPENSSL_uni2utf8() function performs a two-pass conversion of a PKCS#12BMPString (UTF-16BE) to UTF-8. In the second pass, when emitting UTF-8 bytes,the helper function bmp_to_utf8() incorrectly forwards the remaining UTF-16source byte count as the destination buffer capacity to UTF8_putc(). For BMPcode points above U+07FF, UTF-8 requires three bytes, but the forwardedcapacity can be just two bytes. UTF8_putc() then returns -1, and this negativevalue is added to the output length without validation, causing thelength to become negative. The subsequent trailing NUL byte is then writtenat a negative offset, causing write outside of heap allocated buffer.The vulnerability is reachable via the public PKCS12_get_friendlyname() APIwhen parsing attacker-controlled PKCS#12 files. While PKCS12_parse() uses adifferent code path that avoids this issue, PKCS12_get_friendlyname() directlyinvokes the vulnerable function. Exploitation requires an attacker to providea malicious PKCS#12 file to be parsed by the application and the attackercan just trigger a one zero byte write before the allocated buffer.For that reason the issue was assessed as Low severity according to ourSecurity Policy.The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,as the PKCS#12 implementation is outside the OpenSSL FIPS module boundary.OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0 and 1.1.1 are vulnerable to this issue.OpenSSL 1.0.2 is not affected by this issue.

CVE-2025-69421 Severity: Moderate CVSS3 score: 6.2

Description: Issue summary: Processing a malformed PKCS#12 file can trigger a NULL pointerdereference in the PKCS12_item_decrypt_d2i_ex() function.Impact summary: A NULL pointer dereference can trigger a crash which leads toDenial of Service for an application processing PKCS#12 files.The PKCS12_item_decrypt_d2i_ex() function does not check whether the octparameter is NULL before dereferencing it. When called fromPKCS12_unpack_p7encdata() with a malformed PKCS#12 file, this parameter canbe NULL, causing a crash. The vulnerability is limited to Denial of Serviceand cannot be escalated to achieve code execution or memory disclosure.Exploiting this issue requires an attacker to provide a malformed PKCS#12 fileto an application that processes it. For that reason the issue was assessed asLow severity according to our Security Policy.The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,as the PKCS#12 implementation is outside the OpenSSL FIPS module boundary.OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0, 1.1.1 and 1.0.2 are vulnerable to this issue.

CVE-2026-22795 Severity: Moderate CVSS3 score: 6.2

Description: Issue summary: An invalid or NULL pointer dereference can happen inan application processing a malformed PKCS#12 file.Impact summary: An application processing a malformed PKCS#12 file can becaused to dereference an invalid or NULL pointer on memory read, resultingin a Denial of Service.A type confusion vulnerability exists in PKCS#12 parsing code wherean ASN1_TYPE union member is accessed without first validating the type,causing an invalid pointer read.The location is constrained to a 1-byte address space, meaning anyattempted pointer manipulation can only target addresses between 0x00 and 0xFF.This range corresponds to the zero page, which is unmapped on most modernoperating systems and will reliably result in a crash, leading only to aDenial of Service. Exploiting this issue also requires a user or applicationto process a maliciously crafted PKCS#12 file. It is uncommon to acceptuntrusted PKCS#12 files in applications as they are usually used to storeprivate keys which are trusted by definition. For these reasons, the issuewas assessed as Low severity.The FIPS modules in 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,as the PKCS12 implementation is outside the OpenSSL FIPS module boundary.OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0 and 1.1.1 are vulnerable to this issue.OpenSSL 1.0.2 is not affected by this issue.

CVE-2022-48980 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:net: dsa: sja1105: avoid out of bounds access in sja1105_init_l2_policing()The SJA1105 family has 45 L2 policing table entries(SJA1105_MAX_L2_POLICING_COUNT) and SJA1110 has 110(SJA1110_MAX_L2_POLICING_COUNT). Keeping the table structure butaccounting for the difference in port count (5 in SJA1105 vs 10 inSJA1110) does not fully explain the difference. Rather, the SJA1110 alsohas L2 ingress policers for multicast traffic. If a packet is classifiedas multicast, it will be processed by the policer index 99 + SRCPORT.The sja1105_init_l2_policing() function initializes all L2 policers suchthat they don't interfere with normal packet reception by default. To havea common code between SJA1105 and SJA1110, the index of the multicastpolicer for the port is calculated because it's an index that is out ofbounds for SJA1105 but in bounds for SJA1110, and a bounds check isperformed.The code fails to do the proper thing when determining what to do with themulticast policer of port 0 on SJA1105 (ds->num_ports = 5). The "mcast"index will be equal to 45, which is also equal totable->ops->max_entry_count (SJA1105_MAX_L2_POLICING_COUNT). So it passesthrough the check. But at the same time, SJA1105 doesn't have multicastpolicers. So the code programs the SHARINDX field of an out-of-boundselement in the L2 Policing table of the static config.The comparison between index 45 and 45 entries should have determined thecode to not access this policer index on SJA1105, since its memory wasn'teven allocated.With enough bad luck, the out-of-bounds write could even overwrite othervalid kernel data, but in this case, the issue was detected using KASAN.Kernel log:sja1105 spi5.0: Probed switch chip: SJA1105Q==================================================================BUG: KASAN: slab-out-of-bounds in sja1105_setup+0x1cbc/0x2340Write of size 8 at addr ffffff880bd57708 by task kworker/u8:0/8...Workqueue: events_unbound deferred_probe_work_funcCall trace:...sja1105_setup+0x1cbc/0x2340dsa_register_switch+0x1284/0x18d0sja1105_probe+0x748/0x840...Allocated by task 8:...sja1105_setup+0x1bcc/0x2340dsa_register_switch+0x1284/0x18d0sja1105_probe+0x748/0x840...

Description: In the Linux kernel, the following vulnerability has been resolved:staging: greybus: audio_helper: remove unused and wrong debugfs usageIn the greybus audio_helper code, the debugfs file for the dapm has thepotential to be removed and memory will be leaked. There is also thevery real potential for this code to remove ALL debugfs entries from thesystem, and it seems like this is what will really happen if this codeever runs. This all is very wrong as the greybus audio driver did notcreate this debugfs file, the sound core did and controls the lifespanof it.So remove all of the debugfs logic from the audio_helper code as there'sno way it could be correct. If this really is needed, it can come backwith a fixup for the incorrect usage of the debugfs_lookup() call whichis what caused this to be noticed at all.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: ath9k: avoid uninit memory read in ath9k_htc_rx_msg()syzbot is reporting uninit value at ath9k_htc_rx_msg() [1], forioctl(USB_RAW_IOCTL_EP_WRITE) can call ath9k_hif_usb_rx_stream() withpkt_len = 0 but ath9k_hif_usb_rx_stream() uses__dev_alloc_skb(pkt_len + 32, GFP_ATOMIC) based on an assumption thatpkt_len is valid. As a result, ath9k_hif_usb_rx_stream() allocates skbwith uninitialized memory and ath9k_htc_rx_msg() is reading fromuninitialized memory.Since bytes accessed by ath9k_htc_rx_msg() is not known untilath9k_htc_rx_msg() is called, it would be difficult to check minimal validpkt_len at "if (pkt_len > 2 * MAX_RX_BUF_SIZE) {" line inath9k_hif_usb_rx_stream().We have two choices. One is to workaround by adding __GFP_ZERO so thatath9k_htc_rx_msg() sees 0 if pkt_len is invalid. The other is to letath9k_htc_rx_msg() validate pkt_len before accessing. This patch chosethe latter.Note that I'm not sure threshold condition is correct, for I can't finddetails on possible packet length used by this protocol.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: qla4xxx: Add length check when parsing nlattrsThere are three places that qla4xxx parses nlattrs: - qla4xxx_set_chap_entry() - qla4xxx_iface_set_param() - qla4xxx_sysfs_ddb_set_param()and each of them directly converts the nlattr to specific pointer ofstructure without length checking. This could be dangerous as thoseattributes are not validated and a malformed nlattr (e.g., length 0) couldresult in an OOB read that leaks heap dirty data.Add the nla_len check before accessing the nlattr data and return EINVAL ifthe length check fails.

CVE-2023-54232 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:m68k: Only force 030 bus error if PC not in exception table__get_kernel_nofault() does copy data in supervisor mode whenforcing a task backtrace log through /proc/sysrq_trigger.This is expected cause a bus error exception on e.g. NULLpointer dereferencing when logging a kernel task has noworkqueue associated. This bus error ought to be ignored.Our 030 bus error handler is ill equipped to deal with this:Whenever ssw indicates a kernel mode access on a data fault,we don't even attempt to handle the fault and instead alwayssend a SEGV signal (or panic). As a result, the checkfor exception handling at the fault PC (buried insend_sig_fault() which gets called from do_page_fault()eventually) is never used.In contrast, both 040 and 060 access error handlers do notcare whether a fault happened on supervisor mode access,and will call do_page_fault() on those, ultimately honoringthe exception table.Add a check in bus_error030 to call do_page_fault() in casewe do have an entry for the fault PC in our exception table.I had attempted a fix for this earlier in 2019 that did relyon testing pagefault_disabled() (see link below) to achievethe same thing, but this patch should be more generic.Tested on 030 Atari Falcon.

Although this init_waitqueue_head() call will very likelycomplete before this kthread is created and starts running, it ispossible that the calling kthread will be delayed between the calls totorture_create_kthread() and init_waitqueue_head(). In this case, thenew kthread will use the waitqueue head before it is properly initialized,which is not good for the kernel's health and well-being.The above crash happened here: static inline void __add_wait_queue(...) { : if (!(wq->flags & WQ_FLAG_PRIORITY)) <=== Crash hereThe offset of flags from list_head entry in wait_queue_entry is-0x18. If reader_tasks[i].wq.head.next is NULL as allocated reader_taskstructure is zero initialized, the instruction will try to access address0xffffffffffffffe8, which is exactly the fault address listed above.This commit therefore invokes init_waitqueue_head() before creatingthe kthread.

CVE-2023-54317 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:dm flakey: don't corrupt the zero pageWhen we need to zero some range on a block device, the function__blkdev_issue_zero_pages submits a write bio with the bio vector pointingto the zero page. If we use dm-flakey with corrupt bio writes option, itwill corrupt the content of the zero page which results in crashes ofvarious userspace programs. Glibc assumes that memory returned by mmap iszeroed and it uses it for calloc implementation; if the newly mappedmemory is not zeroed, calloc will return non-zeroed memory.Fix this bug by testing if the page is equal to ZERO_PAGE(0) andavoiding the corruption in this case.

CVE-2024-42096 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:x86: stop playing stack games in profile_pc()The 'profile_pc()' function is used for timer-based profiling, whichisn't really all that relevant any more to begin with, but it also endsup making assumptions based on the stack layout that aren't necessarilyvalid.Basically, the code tries to account the time spent in spinlocks to thecaller rather than the spinlock, and while I support that as a concept,it's not worth the code complexity or the KASAN warnings when no seriousprofiling is done using timers anyway these days.And the code really does depend on stack layout that is only true in thesimplest of cases. We've lost the comment at some point (I think whenthe 32-bit and 64-bit code was unified), but it used to say: Assume the lock function has either no stack frame or a copy of eflags from PUSHF.which explains why it just blindly loads a word or two straight off thestack pointer and then takes a minimal look at the values to just checkif they might be eflags or the return pc: Eflags always has bits 22 and up cleared unlike kernel addressesbut that basic stack layout assumption assumes that there isn't any lockdebugging etc going on that would complicate the code and cause a stackframe.It causes KASAN unhappiness reported for years by syzkaller [1] andothers [2].With no real practical reason for this any more, just remove the code.Just for historical interest, here's some background commits relating tothis code from 2006: 0cb91a229364 ("i386: Account spinlocks to the caller during profiling for !FP kernels") 31679f38d886 ("Simplify profile_pc on x86-64")and a code unification from 2009: ef4512882dbe ("x86: time_32/64.c unify profile_pc")but the basics of this thing actually goes back to before the git tree.

CVE-2024-42104 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: add missing check for inode numbers on directory entriesSyzbot reported that mounting and unmounting a specific pattern ofcorrupted nilfs2 filesystem images causes a use-after-free of metadatafile inodes, which triggers a kernel bug in lru_add_fn().As Jan Kara pointed out, this is because the link count of a metadata filegets corrupted to 0, and nilfs_evict_inode(), which is called from iput(),tries to delete that inode (ifile inode in this case).The inconsistency occurs because directories containing the inode numbersof these metadata files that should not be visible in the namespace areread without checking.Fix this issue by treating the inode numbers of these internal files aserrors in the sanity check helper when reading directory folios/pages.Also thanks to Hillf Danton and Matthew Wilcox for their initial mm-layeranalysis.

CVE-2024-42105 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: fix inode number range checksPatch series "nilfs2: fix potential issues related to reserved inodes".This series fixes one use-after-free issue reported by syzbot, caused bynilfs2's internal inode being exposed in the namespace on a corruptedfilesystem, and a couple of flaws that cause problems if the startingnumber of non-reserved inodes written in the on-disk super block isintentionally (or corruptly) changed from its default value. This patch (of 3):In the current implementation of nilfs2, "nilfs->ns_first_ino", whichgives the first non-reserved inode number, is read from the superblock,but its lower limit is not checked.As a result, if a number that overlaps with the inode number range ofreserved inodes such as the root directory or metadata files is set in thesuper block parameter, the inode number test macros (NILFS_MDT_INODE andNILFS_VALID_INODE) will not function properly.In addition, these test macros use left bit-shift calculations using withthe inode number as the shift count via the BIT macro, but the result of ashift calculation that exceeds the bit width of an integer is undefined inthe C specification, so if "ns_first_ino" is set to a large value otherthan the default value NILFS_USER_INO (=11), the macros may potentiallymalfunction depending on the environment.Fix these issues by checking the lower bound of "nilfs->ns_first_ino" andby preventing bit shifts equal to or greater than the NILFS_USER_INOconstant in the inode number test macros.Also, change the type of "ns_first_ino" from signed integer to unsignedinteger to avoid the need for type casting in comparisons such as thelower bound check introduced this time.

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring/rw: fix missing NOWAIT check for O_DIRECT start writeWhen io_uring starts a write, it'll call kiocb_start_write() to bump thesuper block rwsem, preventing any freezes from happening while thatwrite is in-flight. The freeze side will grab that rwsem for writing,excluding any new writers from happening and waiting for existing writesto finish. But io_uring unconditionally uses kiocb_start_write(), whichwill block if someone is currently attempting to freeze the mount point.This causes a deadlock where freeze is waiting for previous writes tocomplete, but the previous writes cannot complete, as the task that issupposed to complete them is blocked waiting on starting a new write.This results in the following stuck trace showing that dependency withthe write blocked starting a new write:task:fio state:D stack:0 pid:886 tgid:886 ppid:876Call trace: __switch_to+0x1d8/0x348 __schedule+0x8e8/0x2248 schedule+0x110/0x3f0 percpu_rwsem_wait+0x1e8/0x3f8 __percpu_down_read+0xe8/0x500 io_write+0xbb8/0xff8 io_issue_sqe+0x10c/0x1020 io_submit_sqes+0x614/0x2110 __arm64_sys_io_uring_enter+0x524/0x1038 invoke_syscall+0x74/0x268 el0_svc_common.constprop.0+0x160/0x238 do_el0_svc+0x44/0x60 el0_svc+0x44/0xb0 el0t_64_sync_handler+0x118/0x128 el0t_64_sync+0x168/0x170INFO: task fsfreeze:7364 blocked for more than 15 seconds.

Description: In the Linux kernel, the following vulnerability has been resolved:net: usb: lan78xx: Fix double free issue with interrupt buffer allocationIn lan78xx_probe(), the buffer `buf` was being freed twice: onceimplicitly through `usb_free_urb(dev->urb_intr)` with the`URB_FREE_BUFFER` flag and again explicitly by `kfree(buf)`. This causeda double free issue.To resolve this, reordered `kmalloc()` and `usb_alloc_urb()` calls tosimplify the initialization sequence and removed the redundant`kfree(buf)`. Now, `buf` is allocated after `usb_alloc_urb()`, ensuringit is correctly managed by `usb_fill_int_urb()` and freed by`usb_free_urb()` as intended.

Then it read the firstbyte of the first 2 bytes to determine the direction.The issue is that only the first byte indicating direction is initializedin current ppp driver code while the second byte is not initialized.For normal BPF programs generated by libpcap, uninitialized data won't beused, so it's not a problem. However, for carefully crafted BPF programs,such as those generated by syzkaller [2], which start reading from offset0, the uninitialized data will be used and caught by KMSAN.[1] https://syzkaller.appspot.com/bug?extid=853242d9c9917165d791[2] https://syzkaller.appspot.com/text?tag=ReproC&x=11994913980000

Description: In the Linux kernel, the following vulnerability has been resolved:tracing: Fix use-after-free in print_graph_function_flags during tracer switchingKairui reported a UAF issue in print_graph_function_flags() duringftrace stress testing [1]. This issue can be reproduced if puting a'mdelay(10)' after 'mutex_unlock(&trace_types_lock)' in s_start(),and executing the following script: $ echo function_graph > current_tracer $ cat trace > /dev/null & $ sleep 5 # Ensure the 'cat' reaches the 'mdelay(10)' point $ echo timerlat > current_tracerThe root cause lies in the two calls to print_graph_function_flagswithin print_trace_line during each s_show(): * One through 'iter->trace->print_line()'; * Another through 'event->funcs->trace()', which is hidden in print_trace_fmt() before print_trace_line returns.Tracer switching only updates the former, while the latter continuesto use the print_line function of the old tracer, which in the scriptabove is print_graph_function_flags.Moreover, when switching from the 'function_graph' tracer to the'timerlat' tracer, s_start only calls graph_trace_close of the'function_graph' tracer to free 'iter->private', but does not setit to NULL. This provides an opportunity for 'event->funcs->trace()'to use an invalid 'iter->private'.To fix this issue, set 'iter->private' to NULL immediately afterfreeing it in graph_trace_close(), ensuring that an invalid pointeris not passed to other tracers. Additionally, clean up the unnecessary'iter->private = NULL' during each 'cat trace' when using wakeup andirqsoff tracers. [1] https://lore.kernel.org/all/20231112150030.84609-1-ryncsn@gmail.com/

It didn't expose them fully, as an attempt to read any ofthose counters leads to a crash like this one:[42021.807566] BUG: kernel NULL pointer dereference, address: 0000000000000028[42021.814463] #PF: supervisor read access in kernel mode[42021.819549] #PF: error_code(0x0000) - not-present page[42021.824636] PGD 0 P4D 0[42021.827145] Oops: 0000 [#1] SMP PTI[42021.830598] CPU: 82 PID: 2843922 Comm: switchto-defaul Kdump: loaded Tainted: G S W I XXX[42021.841697] Hardware name: XXX[42021.849619] RIP: 0010:hw_stat_device_show+0x1e/0x40 [ib_core][42021.855362] Code: 90 90 90 90 90 90 90 90 90 90 90 90 f3 0f 1e fa 0f 1f 44 00 00 49 89 d0 4c 8b 5e 20 48 8b 8f b8 04 00 00 48 81 c7 f0 fa ff ff <48> 8b 41 28 48 29 ce 48 83 c6 d0 48 c1 ee 04 69 d6 ab aa aa aa 48[42021.873931] RSP: 0018:ffff97fe90f03da0 EFLAGS: 00010287[42021.879108] RAX: ffff9406988a8c60 RBX: ffff940e1072d438 RCX: 0000000000000000[42021.886169] RDX: ffff94085f1aa000 RSI: ffff93c6cbbdbcb0 RDI: ffff940c7517aef0[42021.893230] RBP: ffff97fe90f03e70 R08: ffff94085f1aa000 R09: 0000000000000000[42021.900294] R10: ffff94085f1aa000 R11: ffffffffc0775680 R12: ffffffff87ca2530[42021.907355] R13: ffff940651602840 R14: ffff93c6cbbdbcb0 R15: ffff94085f1aa000[42021.914418] FS: 00007fda1a3b9700(0000) GS:ffff94453fb80000(0000) knlGS:0000000000000000[42021.922423] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[42021.928130] CR2: 0000000000000028 CR3: 00000042dcfb8003 CR4: 00000000003726f0[42021.935194] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[42021.942257] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[42021.949324] Call Trace:[42021.951756] [42021.953842] [] ? show_regs+0x64/0x70[42021.959030] [] ? __die+0x78/0xc0[42021.963874] [] ? page_fault_oops+0x2b5/0x3b0[42021.969749] [] ? exc_page_fault+0x1a2/0x3c0[42021.975549] [] ? asm_exc_page_fault+0x26/0x30[42021.981517] [] ? __pfx_show_hw_stats+0x10/0x10 [ib_core][42021.988482] [] ? hw_stat_device_show+0x1e/0x40 [ib_core][42021.995438] [] dev_attr_show+0x1e/0x50[42022.000803] [] sysfs_kf_seq_show+0x81/0xe0[42022.006508] [] seq_read_iter+0xf4/0x410[42022.011954] [] vfs_read+0x16e/0x2f0[42022.017058] [] ksys_read+0x6e/0xe0[42022.022073] [] do_syscall_64+0x6a/0xa0[42022.027441] [] entry_SYSCALL_64_after_hwframe+0x78/0xe2The problem can be reproduced using the following steps: ip netns add foo ip netns exec foo bash cat /sys/class/infiniband/mlx4_0/hw_counters/*The panic occurs because of casting the device pointer into anib_device pointer using container_of() in hw_stat_device_show() iswrong and leads to a memory corruption.However the real problem is that hw counters should never been exposedoutside of the non-init net namespace.Fix this by saving the index of the corresponding attribute group(it might be 1 or 2 depending on the presence of driver-specificattributes) and zeroing the pointer to hw_counters group for compatdevices during the initialization.With this fix applied hw_counters are not available in a non-initnet namespace: find /sys/class/infiniband/mlx4_0/ -name hw_counters /sys/class/infiniband/mlx4_0/ports/1/hw_counters /sys/class/infiniband/mlx4_0/ports/2/hw_counters /sys/class/infiniband/mlx4_0/hw_counters ip netns add foo ip netns exec foo bash find /sys/class/infiniband/mlx4_0/ -name hw_counters

CVE-2025-38211 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/iwcm: Fix use-after-free of work objects after cm_id destructionThe commit 59c68ac31e15 ("iw_cm: free cm_id resources on the lastderef") simplified cm_id resource management by freeing cm_id once allreferences to the cm_id were removed. The references are removed eitherupon completion of iw_cm event handlers or when the application destroysthe cm_id. This commit introduced the use-after-free condition wherecm_id_private object could still be in use by event handler works duringthe destruction of cm_id. The commit aee2424246f9 ("RDMA/iwcm: Fix ause-after-free related to destroying CM IDs") addressed this use-after-free by flushing all pending works at the cm_id destruction.However, still another use-after-free possibility remained. It happenswith the work objects allocated for each cm_id_priv withinalloc_work_entries() during cm_id creation, and subsequently freed indealloc_work_entries() once all references to the cm_id are removed.If the cm_id's last reference is decremented in the event handler work,the work object for the work itself gets removed, and causes the use-after-free BUG below: BUG: KASAN: slab-use-after-free in __pwq_activate_work+0x1ff/0x250 Read of size 8 at addr ffff88811f9cf800 by task kworker/u16:1/147091 CPU: 2 UID: 0 PID: 147091 Comm: kworker/u16:1 Not tainted 6.15.0-rc2+ #27 PREEMPT(voluntary) Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-3.fc41 04/01/2014 Workqueue: 0x0 (iw_cm_wq) Call Trace: dump_stack_lvl+0x6a/0x90 print_report+0x174/0x554 ? __virt_addr_valid+0x208/0x430 ? __pwq_activate_work+0x1ff/0x250 kasan_report+0xae/0x170 ? __pwq_activate_work+0x1ff/0x250 __pwq_activate_work+0x1ff/0x250 pwq_dec_nr_in_flight+0x8c5/0xfb0 process_one_work+0xc11/0x1460 ? __pfx_process_one_work+0x10/0x10 ? assign_work+0x16c/0x240 worker_thread+0x5ef/0xfd0 ? __pfx_worker_thread+0x10/0x10 kthread+0x3b0/0x770 ? __pfx_kthread+0x10/0x10 ? rcu_is_watching+0x11/0xb0 ? _raw_spin_unlock_irq+0x24/0x50 ? rcu_is_watching+0x11/0xb0 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x30/0x70 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1a/0x30 Allocated by task 147416: kasan_save_stack+0x2c/0x50 kasan_save_track+0x10/0x30 __kasan_kmalloc+0xa6/0xb0 alloc_work_entries+0xa9/0x260 [iw_cm] iw_cm_connect+0x23/0x4a0 [iw_cm] rdma_connect_locked+0xbfd/0x1920 [rdma_cm] nvme_rdma_cm_handler+0x8e5/0x1b60 [nvme_rdma] cma_cm_event_handler+0xae/0x320 [rdma_cm] cma_work_handler+0x106/0x1b0 [rdma_cm] process_one_work+0x84f/0x1460 worker_thread+0x5ef/0xfd0 kthread+0x3b0/0x770 ret_from_fork+0x30/0x70 ret_from_fork_asm+0x1a/0x30 Freed by task 147091: kasan_save_stack+0x2c/0x50 kasan_save_track+0x10/0x30 kasan_save_free_info+0x37/0x60 __kasan_slab_free+0x4b/0x70 kfree+0x13a/0x4b0 dealloc_work_entries+0x125/0x1f0 [iw_cm] iwcm_deref_id+0x6f/0xa0 [iw_cm] cm_work_handler+0x136/0x1ba0 [iw_cm] process_one_work+0x84f/0x1460 worker_thread+0x5ef/0xfd0 kthread+0x3b0/0x770 ret_from_fork+0x30/0x70 ret_from_fork_asm+0x1a/0x30 Last potentially related work creation: kasan_save_stack+0x2c/0x50 kasan_record_aux_stack+0xa3/0xb0 __queue_work+0x2ff/0x1390 queue_work_on+0x67/0xc0 cm_event_handler+0x46a/0x820 [iw_cm] siw_cm_upcall+0x330/0x650 [siw] siw_cm_work_handler+0x6b9/0x2b20 [siw] process_one_work+0x84f/0x1460 worker_thread+0x5ef/0xfd0 kthread+0x3b0/0x770 ret_from_fork+0x30/0x70 ret_from_fork_asm+0x1a/0x30This BUG is reproducible by repeating the blktests test case nvme/061for the rdma transport and the siw driver.To avoid the use-after-free of cm_id_private work objects, ensure thatthe last reference to the cm_id is decremented not in the event handlerworks, but in the cm_id destruction context.

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: inline: fix len overflow in ext4_prepare_inline_dataWhen running the following code on an ext4 filesystem with inline_datafeature enabled, it will lead to the bug below. fd = open("file1", O_RDWR | O_CREAT | O_TRUNC, 0666); ftruncate(fd, 30); pwrite(fd, "a", 1, (1UL << 40) + 5UL);That happens because write_begin will succeed as whenext4_generic_write_inline_data calls ext4_prepare_inline_data, pos + lenwill be truncated, leading to ext4_prepare_inline_data parameter to be 6instead of 0x10000000006.Then, later when write_end is called, we hit: BUG_ON(pos + len > EXT4_I(inode)->i_inline_size);at ext4_write_inline_data.Fix it by using a loff_t type for the len parameter inext4_prepare_inline_data instead of an unsigned int.[ 44.545164] ------------[ cut here ]------------[ 44.545530] kernel BUG at fs/ext4/inline.c:240![ 44.545834] Oops: invalid opcode: 0000 [#1] SMP NOPTI[ 44.546172] CPU: 3 UID: 0 PID: 343 Comm: test Not tainted 6.15.0-rc2-00003-g9080916f4863 #45 PREEMPT(full) 112853fcebfdb93254270a7959841d2c6aa2c8bb[ 44.546523] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-debian-1.16.3-2 04/01/2014[ 44.546523] RIP: 0010:ext4_write_inline_data+0xfe/0x100[ 44.546523] Code: 3c 0e 48 83 c7 48 48 89 de 5b 41 5c 41 5d 41 5e 41 5f 5d e9 e4 fa 43 01 5b 41 5c 41 5d 41 5e 41 5f 5d c3 cc cc cc cc cc 0f 0b <0f> 0b 0f 1f 44 00 00 55 41 57 41 56 41 55 41 54 53 48 83 ec 20 49[ 44.546523] RSP: 0018:ffffb342008b79a8 EFLAGS: 00010216[ 44.546523] RAX: 0000000000000001 RBX: ffff9329c579c000 RCX: 0000010000000006[ 44.546523] RDX: 000000000000003c RSI: ffffb342008b79f0 RDI: ffff9329c158e738[ 44.546523] RBP: 0000000000000001 R08: 0000000000000001 R09: 0000000000000000[ 44.546523] R10: 00007ffffffff000 R11: ffffffff9bd0d910 R12: 0000006210000000[ 44.546523] R13: fffffc7e4015e700 R14: 0000010000000005 R15: ffff9329c158e738[ 44.546523] FS: 00007f4299934740(0000) GS:ffff932a60179000(0000) knlGS:0000000000000000[ 44.546523] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 44.546523] CR2: 00007f4299a1ec90 CR3: 0000000002886002 CR4: 0000000000770eb0[ 44.546523] PKRU: 55555554[ 44.546523] Call Trace:[ 44.546523] [ 44.546523] ext4_write_inline_data_end+0x126/0x2d0[ 44.546523] generic_perform_write+0x17e/0x270[ 44.546523] ext4_buffered_write_iter+0xc8/0x170[ 44.546523] vfs_write+0x2be/0x3e0[ 44.546523] __x64_sys_pwrite64+0x6d/0xc0[ 44.546523] do_syscall_64+0x6a/0xf0[ 44.546523] ? __wake_up+0x89/0xb0[ 44.546523] ? xas_find+0x72/0x1c0[ 44.546523] ? next_uptodate_folio+0x317/0x330[ 44.546523] ? set_pte_range+0x1a6/0x270[ 44.546523] ? filemap_map_pages+0x6ee/0x840[ 44.546523] ? ext4_setattr+0x2fa/0x750[ 44.546523] ? do_pte_missing+0x128/0xf70[ 44.546523] ? security_inode_post_setattr+0x3e/0xd0[ 44.546523] ? ___pte_offset_map+0x19/0x100[ 44.546523] ? handle_mm_fault+0x721/0xa10[ 44.546523] ? do_user_addr_fault+0x197/0x730[ 44.546523] ? do_syscall_64+0x76/0xf0[ 44.546523] ? arch_exit_to_user_mode_prepare+0x1e/0x60[ 44.546523] ? irqentry_exit_to_user_mode+0x79/0x90[ 44.546523] entry_SYSCALL_64_after_hwframe+0x55/0x5d[ 44.546523] RIP: 0033:0x7f42999c6687[ 44.546523] Code: 48 89 fa 4c 89 df e8 58 b3 00 00 8b 93 08 03 00 00 59 5e 48 83 f8 fc 74 1a 5b c3 0f 1f 84 00 00 00 00 00 48 8b 44 24 10 0f 05 <5b> c3 0f 1f 80 00 00 00 00 83 e2 39 83 fa 08 75 de e8 23 ff ff ff[ 44.546523] RSP: 002b:00007ffeae4a7930 EFLAGS: 00000202 ORIG_RAX: 0000000000000012[ 44.546523] RAX: ffffffffffffffda RBX: 00007f4299934740 RCX: 00007f42999c6687[ 44.546523] RDX: 0000000000000001 RSI: 000055ea6149200f RDI: 0000000000000003[ 44.546523] RBP: 00007ffeae4a79a0 R08: 0000000000000000 R09: 0000000000000000[ 44.546523] R10: 0000010000000005 R11: 0000000000000202 R12: 0000---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-audio: Fix out-of-bounds read in snd_usb_get_audioformat_uac3()In snd_usb_get_audioformat_uac3(), the length value returned fromsnd_usb_ctl_msg() is used directly for memory allocation withoutvalidation. This length is controlled by the USB device.The allocated buffer is cast to a uac3_cluster_header_descriptorand its fields are accessed without verifying that the bufferis large enough. If the device returns a smaller than expectedlength, this leads to an out-of-bounds read.Add a length check to ensure the buffer is large enough foruac3_cluster_header_descriptor.

CVE-2025-38334 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:x86/sgx: Prevent attempts to reclaim poisoned pagesTL;DR: SGX page reclaim touches the page to copy its contents tosecondary storage. SGX instructions do not gracefully handle machinechecks. Despite this, the existing SGX code will try to reclaim pagesthat it _knows_ are poisoned. Avoid even trying to reclaim poisoned pages.The longer story:Pages used by an enclave only get epc_page->poison set inarch_memory_failure() but they currently stay on sgx_active_page_list untilsgx_encl_release(), with the SGX_EPC_PAGE_RECLAIMER_TRACKED flag untouched.epc_page->poison is not checked in the reclaimer logic meaning that, if otherconditions are met, an attempt will be made to reclaim an EPC page that waspoisoned. This is bad because 1. we don't want that page to end up addedto another enclave and 2. it is likely to cause one core to shut downand the kernel to panic.Specifically, reclaiming uses microcode operations including "EWB" whichaccesses the EPC page contents to encrypt and write them out to non-SGXmemory. Those operations cannot handle MCEs in their accesses other thanby putting the executing core into a special shutdown state (affectingboth threads with HT.) The kernel will subsequently panic on theremaining cores seeing the core didn't enter MCE handler(s) in time.Call sgx_unmark_page_reclaimable() to remove the affected EPC page fromsgx_active_page_list on memory error to stop it being considered forreclaiming.Testing epc_page->poison in sgx_reclaim_pages() would also work but I assumeit's better to add code in the less likely paths.The affected EPC page is not added to &node->sgx_poison_page_list untillater in sgx_encl_release()->sgx_free_epc_page() when it is EREMOVEd.Membership on other lists doesn't change to avoid changing any of thelists' semantics except for sgx_active_page_list. There's a "TBD" commentin arch_memory_failure() about pre-emptive actions, the goal here is notto address everything that it may imply.This also doesn't completely close the time window when a memory errornotification will be fatal (for a not previously poisoned EPC page) --the MCE can happen after sgx_reclaim_pages() has selected its candidatesor even *inside* a microcode operation (actually easy to trigger due tothe amount of time spent in them.)The spinlock in sgx_unmark_page_reclaimable() is safe becausememory_failure() runs in process context and no spinlocks are held,explicitly noted in a mm/memory-failure.c comment.

CVE-2025-38502 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix oob access in cgroup local storageLonial reported that an out-of-bounds access in cgroup local storagecan be crafted via tail calls. Given two programs each utilizing acgroup local storage with a different value size, and one programdoing a tail call into the other. The verifier will validate each ofthe indivial programs just fine. However, in the runtime contextthe bpf_cg_run_ctx holds an bpf_prog_array_item which contains theBPF program as well as any cgroup local storage flavor the programuses. Helpers such as bpf_get_local_storage() pick this up from theruntime context: ctx = container_of(current->bpf_ctx, struct bpf_cg_run_ctx, run_ctx); storage = ctx->prog_item->cgroup_storage[stype]; if (stype == BPF_CGROUP_STORAGE_SHARED) ptr = &READ_ONCE(storage->buf)->data[0]; else ptr = this_cpu_ptr(storage->percpu_buf);For the second program which was called from the originally attachedone, this means bpf_get_local_storage() will pick up the formerprogram's map, not its own. With mismatching sizes, this can resultin an unintended out-of-bounds access.To fix this issue, we need to extend bpf_map_owner with an array ofstorage_cookie[] to match on i) the exact maps from the originalprogram if the second program was using bpf_get_local_storage(), orii) allow the tail call combination if the second program was notusing any of the cgroup local storage maps.

Description: In the Linux kernel, the following vulnerability has been resolved:parisc: Revise __get_user() to probe user read accessBecause of the way read access support is implemented, read accessinterruptions are only triggered at privilege levels 2 and 3. Thekernel executes at privilege level 0, so __get_user() never triggersa read access interruption (code 26). Thus, it is currently possiblefor user code to access a read protected address via a system call.Fix this by probing read access rights at privilege level 3 (PRIV_USER)and setting __gu_err to -EFAULT (-14) if access isn't allowed.Note the cmpiclr instruction does a 32-bit compare because COND macrodoesn't work inside asm.

CVE-2025-39923 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:dmaengine: qcom: bam_dma: Fix DT error handling for num-channels/eesWhen we don't have a clock specified in the device tree, we have no way toensure the BAM is on. This is often the case for remotely-controlled orremotely-powered BAM instances. In this case, we need to read num-channelsfrom the DT to have all the necessary information to complete probing.However, at the moment invalid device trees without clock and withoutnum-channels still continue probing, because the error handling is missingreturn statements. The driver will then later try to read the number ofchannels from the registers. This is unsafe, because it relies on bootfirmware and lucky timing to succeed. Unfortunately, the lack of propererror handling here has been abused for several Qualcomm SoCs upstream,causing early boot crashes in several situations [1, 2].Avoid these early crashes by erroring out when any of the required DTproperties are missing. Note that this will break some of the existing DTsupstream (mainly BAM instances related to the crypto engine). However,clearly these DTs have never been tested properly, since the error in thekernel log was just ignored. It's safer to disable the crypto engine forthese broken DTBs.[1]: https://lore.kernel.org/r/CY01EKQVWE36.B9X5TDXAREPF@fairphone.com/[2]: https://lore.kernel.org/r/20230626145959.646747-1-krzysztof.kozlowski@linaro.org/

CVE-2025-39998 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: target: target_core_configfs: Add length check to avoid buffer overflowA buffer overflow arises from the usage of snprintf to write into thebuffer "buf" in target_lu_gp_members_show function located in/drivers/target/target_core_configfs.c. This buffer is allocated withsize LU_GROUP_NAME_BUF (256 bytes).snprintf(...) formats multiple strings into buf with the HBA name(hba->hba_group.cg_item), a slash character, a devicename (dev->dev_group.cg_item) and a newline character, the total formatted stringlength may exceed the buffer size of 256 bytes.Since snprintf() returns the total number of bytes that would have beenwritten (the length of %s/%sn ), this value may exceed the buffer length(256 bytes) passed to memcpy(), this will ultimately cause functionmemcpy reporting a buffer overflow error.An additional check of the return value of snprintf() can avoid thisbuffer overflow.

CVE-2025-40049 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:Squashfs: fix uninit-value in squashfs_get_parentSyzkaller reports a "KMSAN: uninit-value in squashfs_get_parent" bug.This is caused by open_by_handle_at() being called with a file handlecontaining an invalid parent inode number. In particular the inode numberis that of a symbolic link, rather than a directory.Squashfs_get_parent() gets called with that symbolic link inode, andaccesses the parent member field. unsigned int parent_ino = squashfs_i(inode)->parent;Because non-directory inodes in Squashfs do not have a parent value, thisis uninitialised, and this causes an uninitialised value access.The fix is to initialise parent with the invalid inode 0, which will causean EINVAL error to be returned.Regular inodes used to share the parent field with the block_list_startfield. This is removed in this commit to enable the parent field tocontain the invalid inode number 0.

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: guard against EA inode refcount underflow in xattr updatesyzkaller found a path where ext4_xattr_inode_update_ref() reads an EAinode refcount that is already <= 0 and then applies ref_change (often-1). That lets the refcount underflow and we proceed with a bogus value,triggering errors like: EXT4-fs error: EA inode ref underflow: ref_count=-1 ref_change=-1 EXT4-fs warning: ea_inode dec ref err=-117Make the invariant explicit: if the current refcount is non-positive,treat this as on-disk corruption, emit ext4_error_inode(), and fail theoperation with -EFSCORRUPTED instead of updating the refcount. Delete theWARN_ONCE() as negative refcounts are now impossible; keep error reportingin ext4_error_inode().This prevents the underflow and the follow-on orphan/cleanup churn.

So why is the fuse server calling fuse_file_put?The commit message for the fstest sheds some light on that:"By closing the file descriptor before calling io_destroy, you prettymuch guarantee that the last put on the ioctx will be done in interruptcontext (during I/O completion).Aha. AIO fgets a new struct file from the fd when it queues the ioctx.The completion of the FUSE_WRITE command from userspace causes the fuseserver to call the AIO completion function. The completion puts thestruct file, queuing a delayed fput to the fuse server task. When thefuse server task returns to userspace, it has to run the delayed fput,which in the case of a fuseblk server, it does synchronously.Sending the FUSE_RELEASE command sychronously from fuse server threadsis a bad idea because a client program can initiate enough simultaneousAIOs such that all the fuse server threads end up in delayed_fput, andnow there aren't any threads left to handle the queued fuse commands.Fix this by only using asynchronous fputs when closing files, and leavea comment explaining why.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: cdns3: gadget: Use-after-free during failed initialization and exit of cdnsp gadgetIn the __cdnsp_gadget_init() and cdnsp_gadget_exit() functions, the gadgetstructure (pdev->gadget) was freed before its endpoints.The endpoints are linked via the ep_list in the gadget structure.Freeing the gadget first leaves dangling pointers in the endpoint list.When the endpoints are subsequently freed, this results in a use-after-free.Fix:By separating the usb_del_gadget_udc() operation into distinct "del" and"put" steps, cdnsp_gadget_free_endpoints() can be executed prior to thefinal release of the gadget structure with usb_put_gadget().A patch similar to bb9c74a5bd14("usb: dwc3: gadget: Free gadget structure only after freeing endpoints").

CVE-2025-68183 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:ima: don't clear IMA_DIGSIG flag when setting or removing non-IMA xattrCurrently when both IMA and EVM are in fix mode, the IMA signature willbe reset to IMA hash if a program first stores IMA signature insecurity.ima and then writes/removes some other security xattr for thefile.For example, on Fedora, after booting the kernel with "ima_appraise=fixevm=fix ima_policy=appraise_tcb" and installing rpm-plugin-ima,installing/reinstalling a package will not make good reference IMAsignature generated. Instead IMA hash is generated, # getfattr -m - -d -e hex /usr/bin/bash # file: usr/bin/bash security.ima=0x0404...This happens because when setting security.selinux, the IMA_DIGSIG flagthat had been set early was cleared. As a result, IMA hash is generatedwhen the file is closed.Similarly, IMA signature can be cleared on file close after removingsecurity xattr like security.evm or setting/removing ACL.Prevent replacing the IMA file signature with a file hash, by preventingthe IMA_DIGSIG flag from being reset.Here's a minimal C reproducer which sets security.selinux as the laststep which can also replaced by removing security.evm or setting ACL, #include #include #include #include #include #include int main() { const char* file_path = "/usr/sbin/test_binary"; const char* hex_string = "030204d33204490066306402304"; int length = strlen(hex_string); char* ima_attr_value; int fd; fd = open(file_path, O_WRONLY|O_CREAT|O_EXCL, 0644); if (fd == -1) { perror("Error opening file"); return 1; } ima_attr_value = (char*)malloc(length / 2 ); for (int i = 0, j = 0; i < length; i += 2, j++) { sscanf(hex_string + i, "%2hhx", &ima_attr_value[j]); } if (fsetxattr(fd, "security.ima", ima_attr_value, length/2, 0) == -1) { perror("Error setting extended attribute"); close(fd); return 1; } const char* selinux_value= "system_u:object_r:bin_t:s0"; if (fsetxattr(fd, "security.selinux", selinux_value, strlen(selinux_value), 0) == -1) { perror("Error setting extended attribute"); close(fd); return 1; } close(fd); return 0; }

Description: In the Linux kernel, the following vulnerability has been resolved:backlight: led-bl: Add devlink to supplier LEDsLED Backlight is a consumer of one or multiple LED class devices, butdevlink is currently unable to create correct supplier-producer links whenthe supplier is a class device. It creates instead a link where thesupplier is the parent of the expected device.One consequence is that removal order is not correctly enforced.Issues happen for example with the following sections in a device treeoverlay: // An LED driver chip pca9632@62 { compatible = "nxp,pca9632"; reg = <0x62>; // ... addon_led_pwm: led-pwm@3 { reg = <3>; label = "addon:led:pwm"; }; }; backlight-addon { compatible = "led-backlight"; leds = <&addon_led_pwm>; brightness-levels = <255>; default-brightness-level = <255>; };In this example, the devlink should be created between the backlight-addon(consumer) and the pca9632@62 (supplier). Instead it is created between thebacklight-addon (consumer) and the parent of the pca9632@62, which istypically the I2C bus adapter.On removal of the above overlay, the LED driver can be removed before thebacklight device, resulting in: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000010 ... Call trace: led_put+0xe0/0x140 devm_led_release+0x6c/0x98Another way to reproduce the bug without any device tree overlays isunbinding the LED class device (pca9632@62) before unbinding the consumer(backlight-addon): echo 11-0062 >/sys/bus/i2c/drivers/leds-pca963x/unbind echo ...backlight-dock >/sys/bus/platform/drivers/led-backlight/unbindFix by adding a devlink between the consuming led-backlight device and thesupplying LED device, as other drivers and subsystems do as well.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: log new dentries when logging parent dir of a conflicting inodeIf we log the parent directory of a conflicting inode, we are not loggingthe new dentries of the directory, so when we finish we have the parentdirectory's inode marked as logged but we did not log its new dentries.As a consequence if the parent directory is explicitly fsynced later andit does not have any new changes since we logged it, the fsync is a no-opand after a power failure the new dentries are missing.Example scenario: $ mkdir foo $ sync $rmdir foo $ mkdir dir1 $ mkdir dir2 # A file with the same name and parent as the directory we just deleted # and was persisted in a past transaction. So the deleted directory's # inode is a conflicting inode of this new file's inode. $ touch foo $ ln foo dir2/link # The fsync on dir2 will log the parent directory (".") because the # conflicting inode (deleted directory) does not exists anymore, but it # it does not log its new dentries (dir1). $ xfs_io -c "fsync" dir2 # This fsync on the parent directory is no-op, since the previous fsync # logged it (but without logging its new dentries). $ xfs_io -c "fsync" . # After log replay dir1 is missing.Fix this by ensuring we log new dir dentries whenever we log the parentdirectory of a no longer existing conflicting inode.A test case for fstests will follow soon.

CVE-2022-50650 Severity: Moderate CVSS3 score: 6.0

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix reference state management for synchronous callbacksCurrently, verifier verifies callback functions (sync and async) as ifthey will be executed once, (i.e. it explores execution state as if thefunction was being called once). The next insn to explore is set tostart of subprog and the exit from nested frame is handled usingcurframe > 0 and prepare_func_exit. In case of async callback it uses acustomized variant of push_stack simulating a kind of branch to set upcustom state and execution context for the async callback.While this approach is simple and works when callback really will beexecuted only once, it is unsafe for all of our current helpers whichare for_each style, i.e. they execute the callback multiple times.A callback releasing acquired references of the caller may do somultiple times, but currently verifier sees it as one call inside theframe, which then returns to caller. Hence, it thinks it released somereference that the cb e.g. got access through callback_ctx (registerfilled inside cb from spilled typed register on stack).Similarly, it may see that an acquire call is unpaired inside thecallback, so the caller will copy the reference state of callback andthen will have to release the register with new ref_obj_ids. But again,the callback may execute multiple times, but the verifier will onlyaccount for acquired references for a single symbolic execution of thecallback, which will cause leaks.Note that for async callback case, things are different. While currentlywe have bpf_timer_set_callback which only executes it once, even formultiple executions it would be safe, as reference state is NULL andcheck_reference_leak would force program to release state beforeBPF_EXIT. The state is also unaffected by analysis for the caller frame.Hence async callback is safe.Since we want the reference state to be accessible, e.g. for pointersloaded from stack through callback_ctx's PTR_TO_STACK, we still have tocopy caller's reference_state to callback's bpf_func_state, but weenforce that whatever references it adds to that reference_state hasbeen released before it hits BPF_EXIT. This requires introducing a newcallback_ref member in the reference state to distinguish between callervs callee references. Hence, check_reference_leak now errors out if itsees we are in callback_fn and we have not released callback_ref refs.Since there can be multiple nested callbacks, like frame 0 -> cb1 -> cb2etc. we need to also distinguish between whether this particular refbelongs to this callback frame or parent, and only error for our own, sowe store state->frameno (which is always non-zero for callbacks).In short, callbacks can read parent reference_state, but cannot mutateit, to be able to use pointers acquired by the caller. They must onlyundo their changes (by releasing their own acquired_refs beforeBPF_EXIT) on top of caller reference_state before returning (at whichpoint the caller and callback state will match anyway, so no need tocopy it back to caller).

CVE-2023-53586 Severity: Moderate CVSS3 score: 6.0

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: target: Fix multiple LUN_RESET handlingThis fixes a bug where an initiator thinks a LUN_RESET has cleaned uprunning commands when it hasn't. The bug was added in commit 51ec502a3266("target: Delete tmr from list before processing").The problem occurs when: 1. We have N I/O cmds running in the target layer spread over 2 sessions. 2. The initiator sends a LUN_RESET for each session. 3. session1's LUN_RESET loops over all the running commands from both sessions and moves them to its local drain_task_list. 4. session2's LUN_RESET does not see the LUN_RESET from session1 because the commit above has it remove itself. session2 also does not see any commands since the other reset moved them off the state lists. 5. sessions2's LUN_RESET will then complete with a successful response. 6. sessions2's inititor believes the running commands on its session are now cleaned up due to the successful response and cleans up the running commands from its side. It then restarts them. 7. The commands do eventually complete on the backend and the target starts to return aborted task statuses for them. The initiator will either throw a invalid ITT error or might accidentally lookup a new task if the ITT has been reallocated already.Fix the bug by reverting the patch, and serialize the execution ofLUN_RESETs and Preempt and Aborts.Also prevent us from waiting on LUN_RESETs in core_tmr_drain_tmr_list,because it turns out the original patch fixed a bug that was notmentioned. For LUN_RESET1 core_tmr_drain_tmr_list can see a secondLUN_RESET and wait on it. Then the second reset will runcore_tmr_drain_tmr_list and see the first reset and wait on it resulting ina deadlock.

Description: In the Linux kernel, the following vulnerability has been resolved:uio_hv_generic: Don't free decrypted memoryIn CoCo VMs it is possible for the untrusted host to causeset_memory_encrypted() or set_memory_decrypted() to fail such that anerror is returned and the resulting memory is shared. Callers need totake care to handle these errors to avoid returning decrypted (shared)memory to the page allocator, which could lead to functional or securityissues.The VMBus device UIO driver could free decrypted/shared pages ifset_memory_decrypted() fails. Check the decrypted field in the gpadlto decide whether to free the memory.

CVE-2024-41038 Severity: Moderate CVSS3 score: 6.0

Description: In the Linux kernel, the following vulnerability has been resolved:firmware: cs_dsp: Prevent buffer overrun when processing V2 alg headersCheck that all fields of a V2 algorithm header fit into the availablefirmware data buffer.The wmfw V2 format introduced variable-length strings in the algorithmblock header. This means the overall header length is variable, and theposition of most fields varies depending on the length of the stringfields. Each field must be checked to ensure that it does not overflowthe firmware data buffer.As this ia bugfix patch, the fixes avoid making any significant change tothe existing code. This makes it easier to review and less likely tointroduce new bugs.

CVE-2024-47742 Severity: Moderate CVSS3 score: 6.0

Description: In the Linux kernel, the following vulnerability has been resolved:firmware_loader: Block path traversalMost firmware names are hardcoded strings, or are constructed from fairlyconstrained format strings where the dynamic parts are just some hexnumbers or such.However, there are a couple codepaths in the kernel where firmware filenames contain string components that are passed through from a device orsemi-privileged userspace; the ones I could find (not counting interfacesthat require root privileges) are: - lpfc_sli4_request_firmware_update() seems to construct the firmware filename from "ModelName", a string that was previously parsed out of some descriptor ("Vital Product Data") in lpfc_fill_vpd() - nfp_net_fw_find() seems to construct a firmware filename from a model name coming from nfp_hwinfo_lookup(pf->hwinfo, "nffw.partno"), which I think parses some descriptor that was read from the device. (But this case likely isn't exploitable because the format string looks like "netronome/nic_%s", and there shouldn't be any *folders* starting with "netronome/nic_". The previous case was different because there, the "%s" is *at the start* of the format string.) - module_flash_fw_schedule() is reachable from the ETHTOOL_MSG_MODULE_FW_FLASH_ACT netlink command, which is marked as GENL_UNS_ADMIN_PERM (meaning CAP_NET_ADMIN inside a user namespace is enough to pass the privilege check), and takes a userspace-provided firmware name. (But I think to reach this case, you need to have CAP_NET_ADMIN over a network namespace that a special kind of ethernet device is mapped into, so I think this is not a viable attack path in practice.)Fix it by rejecting any firmware names containing ".." path components.For what it's worth, I went looking and haven't found any USB devicedrivers that use the firmware loader dangerously.

CVE-2024-56566 Severity: Moderate CVSS3 score: 6.0

Description: In the Linux kernel, the following vulnerability has been resolved:mm/slub: Avoid list corruption when removing a slab from the full listBoot with slub_debug=UFPZ.If allocated object failed in alloc_consistency_checks, all objects ofthe slab will be marked as used, and then the slab will be removed fromthe partial list.When an object belonging to the slab got freed later, the remove_full()function is called. Because the slab is neither on the partial list noron the full list, it eventually lead to a list corruption (actually alist poison being detected).So we need to mark and isolate the slab page with metadata corruption,do not put it back in circulation.Because the debug caches avoid all the fastpaths, reusing the frozen bitto mark slab page with metadata corruption seems to be fine.[ 4277.385669] list_del corruption, ffffea00044b3e50->next is LIST_POISON1 (dead000000000100)[ 4277.387023] ------------[ cut here ]------------[ 4277.387880] kernel BUG at lib/list_debug.c:56![ 4277.388680] invalid opcode: 0000 [#1] PREEMPT SMP PTI[ 4277.389562] CPU: 5 PID: 90 Comm: kworker/5:1 Kdump: loaded Tainted: G OE 6.6.1-1 #1[ 4277.392113] Workqueue: xfs-inodegc/vda1 xfs_inodegc_worker [xfs][ 4277.393551] RIP: 0010:__list_del_entry_valid_or_report+0x7b/0xc0[ 4277.394518] Code: 48 91 82 e8 37 f9 9a ff 0f 0b 48 89 fe 48 c7 c7 28 49 91 82 e8 26 f9 9a ff 0f 0b 48 89 fe 48 c7 c7 58 49 91[ 4277.397292] RSP: 0018:ffffc90000333b38 EFLAGS: 00010082[ 4277.398202] RAX: 000000000000004e RBX: ffffea00044b3e50 RCX: 0000000000000000[ 4277.399340] RDX: 0000000000000002 RSI: ffffffff828f8715 RDI: 00000000ffffffff[ 4277.400545] RBP: ffffea00044b3e40 R08: 0000000000000000 R09: ffffc900003339f0[ 4277.401710] R10: 0000000000000003 R11: ffffffff82d44088 R12: ffff888112cf9910[ 4277.402887] R13: 0000000000000001 R14: 0000000000000001 R15: ffff8881000424c0[ 4277.404049] FS: 0000000000000000(0000) GS:ffff88842fd40000(0000) knlGS:0000000000000000[ 4277.405357] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 4277.406389] CR2: 00007f2ad0b24000 CR3: 0000000102a3a006 CR4: 00000000007706e0[ 4277.407589] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 4277.408780] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[ 4277.410000] PKRU: 55555554[ 4277.410645] Call Trace:[ 4277.411234] [ 4277.411777] ? die+0x32/0x80[ 4277.412439] ? do_trap+0xd6/0x100[ 4277.413150] ? __list_del_entry_valid_or_report+0x7b/0xc0[ 4277.414158] ? do_error_trap+0x6a/0x90[ 4277.414948] ? __list_del_entry_valid_or_report+0x7b/0xc0[ 4277.415915] ? exc_invalid_op+0x4c/0x60[ 4277.416710] ? __list_del_entry_valid_or_report+0x7b/0xc0[ 4277.417675] ? asm_exc_invalid_op+0x16/0x20[ 4277.418482] ? __list_del_entry_valid_or_report+0x7b/0xc0[ 4277.419466] ? __list_del_entry_valid_or_report+0x7b/0xc0[ 4277.420410] free_to_partial_list+0x515/0x5e0[ 4277.421242] ? xfs_iext_remove+0x41a/0xa10 [xfs][ 4277.422298] xfs_iext_remove+0x41a/0xa10 [xfs][ 4277.423316] ? xfs_inodegc_worker+0xb4/0x1a0 [xfs][ 4277.424383] xfs_bmap_del_extent_delay+0x4fe/0x7d0 [xfs][ 4277.425490] __xfs_bunmapi+0x50d/0x840 [xfs][ 4277.426445] xfs_itruncate_extents_flags+0x13a/0x490 [xfs][ 4277.427553] xfs_inactive_truncate+0xa3/0x120 [xfs][ 4277.428567] xfs_inactive+0x22d/0x290 [xfs][ 4277.429500] xfs_inodegc_worker+0xb4/0x1a0 [xfs][ 4277.430479] process_one_work+0x171/0x340[ 4277.431227] worker_thread+0x277/0x390[ 4277.431962] ? __pfx_worker_thread+0x10/0x10[ 4277.432752] kthread+0xf0/0x120[ 4277.433382] ? __pfx_kthread+0x10/0x10[ 4277.434134] ret_from_fork+0x2d/0x50[ 4277.434837] ? __pfx_kthread+0x10/0x10[ 4277.435566] ret_from_fork_asm+0x1b/0x30[ 4277.436280]

CVE-2022-50483 Severity: Moderate CVSS3 score: 5.9

Description: In the Linux kernel, the following vulnerability has been resolved:net: enetc: avoid buffer leaks on xdp_do_redirect() failureBefore enetc_clean_rx_ring_xdp() calls xdp_do_redirect(), each softwareBD in the RX ring between index orig_i and i can have one of 2 refcountvalues on its page.We are the owner of the current buffer that is being processed, so therefcount will be at least 1.If the current owner of the buffer at the diametrically opposed indexin the RX ring (i.o.w, the other half of this page) has not yet calledkfree(), this page's refcount could even be 2.enetc_page_reusable() in enetc_flip_rx_buff() tests for the pagerefcount against 1, and [ if it's 2 ] does not attempt to reuse it.But if enetc_flip_rx_buff() is put after the xdp_do_redirect() call,the page refcount can have one of 3 values. It can also be 0, if thereis no owner of the other page half, and xdp_do_redirect() for thisbuffer ran so far that it triggered a flush of the devmap/cpumap bulkqueue, and the consumers of those bulk queues also freed the buffer,all by the time xdp_do_redirect() returns the execution back to enetc.This is the reason why enetc_flip_rx_buff() is called beforexdp_do_redirect(), but there is a big flaw with that reasoning:enetc_flip_rx_buff() will set rx_swbd->page = NULL on both sides of theenetc_page_reusable() branch, and if xdp_do_redirect() returns an error,we call enetc_xdp_free(), which does not deal gracefully with that.In fact, what happens is quite special. The page refcounts start as 1.enetc_flip_rx_buff() figures they're reusable, transfers theserx_swbd->page pointers to a different rx_swbd in enetc_reuse_page(), andbumps the refcount to 2. When xdp_do_redirect() later returns an error,we call the no-op enetc_xdp_free(), but we still haven't lost thereference to that page. A copy of it is still at rx_ring->next_to_alloc,but that has refcount 2 (and there are no concurrent owners of it inflight, to drop the refcount). What really kills the system is whenwe'll flip the rx_swbd->page the second time around. With an updatedrefcount of 2, the page will not be reusable and we'll really leak it.Then enetc_new_page() will have to allocate more pages, which will theneventually leak again on further errors from xdp_do_redirect().The problem, summarized, is that we zeroize rx_swbd->page before we'recompletely done with it, and this makes it impossible for the error pathto do something with it.Since the packet is potentially multi-buffer and therefore therx_swbd->page is potentially an array, manual passing of the oldpointers between enetc_flip_rx_buff() and enetc_xdp_free() is a bitdifficult.For the sake of going with a simple solution, we accept the possibilityof racing with xdp_do_redirect(), and we move the flip procedure toexecute only on the redirect success path. By racing, I mean that thepage may be deemed as not reusable by enetc (having a refcount of 0),but there will be no leak in that case, either.Once we accept that, we have something better to do with buffers onXDP_REDIRECT failure. Since we haven't performed half-page flipping yet,we won't, either (and this way, we can avoid enetc_xdp_free()completely, which gives the entire page to the slab allocator).Instead, we'll call enetc_xdp_drop(), which will recycle this half ofthe buffer back to the RX ring.

CVE-2024-56703 Severity: Moderate CVSS3 score: 5.9

Description: In the Linux kernel, the following vulnerability has been resolved:ipv6: Fix soft lockups in fib6_select_path under high next hop churnSoft lockups have been observed on a cluster of Linux-based edge routerslocated in a highly dynamic environment. Using the `bird` service, theserouters continuously update BGP-advertised routes due to frequentlychanging nexthop destinations, while also managing significant IPv6traffic. The lockups occur during the traversal of the multipathcircular linked-list in the `fib6_select_path` function, particularlywhile iterating through the siblings in the list. The issue typicallyarises when the nodes of the linked list are unexpectedly deletedconcurrently on a different core-indicated by their 'next' and'previous' elements pointing back to the node itself and their referencecount dropping to zero. This results in an infinite loop, leading to asoft lockup that triggers a system panic via the watchdog timer.Apply RCU primitives in the problematic code sections to resolve theissue. Where necessary, update the references to fib6_siblings toannotate or use the RCU APIs.Include a test script that reproduces the issue. The scriptperiodically updates the routing table while generating a heavy loadof outgoing IPv6 traffic through multiple iperf3 clients. Itconsistently induces infinite soft lockups within a couple of minutes.Kernel log: 0 [ffffbd13003e8d30] machine_kexec at ffffffff8ceaf3eb 1 [ffffbd13003e8d90] __crash_kexec at ffffffff8d0120e3 2 [ffffbd13003e8e58] panic at ffffffff8cef65d4 3 [ffffbd13003e8ed8] watchdog_timer_fn at ffffffff8d05cb03 4 [ffffbd13003e8f08] __hrtimer_run_queues at ffffffff8cfec62f 5 [ffffbd13003e8f70] hrtimer_interrupt at ffffffff8cfed756 6 [ffffbd13003e8fd0] __sysvec_apic_timer_interrupt at ffffffff8cea01af 7 [ffffbd13003e8ff0] sysvec_apic_timer_interrupt at ffffffff8df1b83d-- -- 8 [ffffbd13003d3708] asm_sysvec_apic_timer_interrupt at ffffffff8e000ecb [exception RIP: fib6_select_path+299] RIP: ffffffff8ddafe7b RSP: ffffbd13003d37b8 RFLAGS: 00000287 RAX: ffff975850b43600 RBX: ffff975850b40200 RCX: 0000000000000000 RDX: 000000003fffffff RSI: 0000000051d383e4 RDI: ffff975850b43618 RBP: ffffbd13003d3800 R8: 0000000000000000 R9: ffff975850b40200 R10: 0000000000000000 R11: 0000000000000000 R12: ffffbd13003d3830 R13: ffff975850b436a8 R14: ffff975850b43600 R15: 0000000000000007 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 9 [ffffbd13003d3808] ip6_pol_route at ffffffff8ddb030c10 [ffffbd13003d3888] ip6_pol_route_input at ffffffff8ddb068c11 [ffffbd13003d3898] fib6_rule_lookup at ffffffff8ddf02b512 [ffffbd13003d3928] ip6_route_input at ffffffff8ddb0f4713 [ffffbd13003d3a18] ip6_rcv_finish_core.constprop.0 at ffffffff8dd950d014 [ffffbd13003d3a30] ip6_list_rcv_finish.constprop.0 at ffffffff8dd9627415 [ffffbd13003d3a98] ip6_sublist_rcv at ffffffff8dd9647416 [ffffbd13003d3af8] ipv6_list_rcv at ffffffff8dd9661517 [ffffbd13003d3b60] __netif_receive_skb_list_core at ffffffff8dc16fec18 [ffffbd13003d3be0] netif_receive_skb_list_internal at ffffffff8dc176b319 [ffffbd13003d3c50] napi_gro_receive at ffffffff8dc565b920 [ffffbd13003d3c80] ice_receive_skb at ffffffffc087e4f5 [ice]21 [ffffbd13003d3c90] ice_clean_rx_irq at ffffffffc0881b80 [ice]22 [ffffbd13003d3d20] ice_napi_poll at ffffffffc088232f [ice]23 [ffffbd13003d3d80] __napi_poll at ffffffff8dc1800024 [ffffbd13003d3db8] net_rx_action at ffffffff8dc1858125 [ffffbd13003d3e40] __do_softirq at ffffffff8df352e926 [ffffbd13003d3eb0] run_ksoftirqd at ffffffff8ceffe4727 [ffffbd13003d3ec0] smpboot_thread_fn at ffffffff8cf36a3028 [ffffbd13003d3ee8] kthread at ffffffff8cf2b39f29 [ffffbd13003d3f28] ret_from_fork at ffffffff8ce5fa6430 [ffffbd13003d3f50] ret_from_fork_asm at ffffffff8ce03cbb

Description: In the Linux kernel, the following vulnerability has been resolved:netlabel: Fix NULL pointer exception caused by CALIPSO on IPv4 socketsWhen calling netlbl_conn_setattr(), addr->sa_family is usedto determine the function behavior. If sk is an IPv4 socket,but the connect function is called with an IPv6 address,the function calipso_sock_setattr() is triggered.Inside this function, the following code is executed:sk_fullsock(__sk) ? inet_sk(__sk)->pinet6 : NULL;Since sk is an IPv4 socket, pinet6 is NULL, leading to anull pointer dereference.This patch fixes the issue by checking if inet6_sk(sk)returns a NULL pointer before accessing pinet6.

CVE-2025-68768 Severity: Moderate CVSS3 score: 5.9

Description: In the Linux kernel, the following vulnerability has been resolved:inet: frags: flush pending skbs in fqdir_pre_exit()We have been seeing occasional deadlocks on pernet_ops_rwsem sinceSeptember in NIPA. The stuck task was usually modprobe (often loadinga driver like ipvlan), trying to take the lock as a Writer.lockdep does not track readers for rwsems so the read wasn't obviousfrom the reports.On closer inspection the Reader holding the lock was conntrack loopingforever in nf_conntrack_cleanup_net_list(). Based on past experiencewith occasional NIPA crashes I looked thru the tests which run beforethe crash and noticed that the crash follows ip_defrag.sh. An immediatered flag. Scouring thru (de)fragmentation queues reveals skbs sittingaround, holding conntrack references.The problem is that since conntrack depends on nf_defrag_ipv6,nf_defrag_ipv6 will load first. Since nf_defrag_ipv6 loads first itsnetns exit hooks run _after_ conntrack's netns exit hook.Flush all fragment queue SKBs during fqdir_pre_exit() to releaseconntrack references before conntrack cleanup runs. Also flushthe queues in timer expiry handlers when they discover fqdir->deadis set, in case packet sneaks in while we're running the pre_exitflush.The commit under Fixes is not exactly the culprit, but I thinkpreviously the timer firing would eventually unblock the spinningconntrack.

CVE-2026-0990 Severity: Moderate CVSS3 score: 5.9

Description: A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications.

Description: In the Linux kernel, the following vulnerability has been resolved:binder: fix UAF of ref->proc caused by race conditionA transaction of type BINDER_TYPE_WEAK_HANDLE can fail to increment thereference for a node. In this case, the target proc normally releasesthe failed reference upon close as expected. However, if the target isdying in parallel the call will race with binder_deferred_release(), sothe target could have released all of its references by now leaving thecleanup of the new failed reference unhandled.The transaction then ends and the target proc gets released making theref->proc now a dangling pointer. Later on, ref->node is closed and weattempt to take spin_lock(&ref->proc->inner_lock), which leads to theuse-after-free bug reported below.

As far as I can tell, there's no reason for the mutex to beheld while the gadget core calls a gadget driver's ->bind or ->unbindroutine, or while a UDC is being started or stopped. (This accountsfor link #1 in the chain above, where the mutex is held while thedwc2_hsotg_udc is started as part of driver probing.)Gadget drivers' ->disconnect callbacks are problematic. Even thoughusb_gadget_disconnect() will now acquire the udc_mutex, there's awindow in usb_gadget_bind_driver() between the times when the mutex isreleased and the ->bind callback is invoked. If a disconnect occurredduring that window, we could call the driver's ->disconnect routinebefore its ->bind routine. To prevent this from happening, it will benecessary to prevent a UDC from connecting while it has no gadgetdriver. This should be done already but it doesn't seem to be;currently usb_gadget_connect() has no check for this. Such a checkwill have to be added later.Some degree of mutual exclusion is required in soft_connect_store(),which can dereference udc->driver at arbitrary times since it is asysfs callback. The solution here is to acquire the gadget's devicelock rather than the udc_mutex. Since the driver core guarantees thatthe device lock is always held during driver binding and unbinding,this will make the accesses in soft_connect_store() mutually exclusivewith any changes to udc->driver.Lastly, it turns out there is one place which should hold theudc_mutex but currently does not: The function_show() routine needsprotection while it dereferences udc->driver. The missing lock andunlock calls are added.

Description: An authentication bypass vulnerability exists in libcurl <8.0.0 in the FTP connection reuse feature that can result in wrong credentials being used during subsequent transfers. Previously created connections are kept in a connection pool for reuse if they match the current setup. However, certain FTP settings such as CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC, and CURLOPT_USE_SSL were not included in the configuration match checks, causing them to match too easily. This could lead to libcurl using the wrong credentials when performing a transfer, potentially allowing unauthorized access to sensitive information.

Description: An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously established SSH connection despite the fact that an SSH option was modified, which should have prevented reuse. libcurl maintains a pool of previously used connections to reuse them for subsequent transfers if the configurations match. However, two SSH settings were omitted from the configuration check, allowing them to match easily, potentially leading to the reuse of an inappropriate connection.

CVE-2023-53536 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:blk-crypto: make blk_crypto_evict_key() more robustIf blk_crypto_evict_key() sees that the key is still in-use (due to abug) or that ->keyslot_evict failed, it currently just returns whileleaving the key linked into the keyslot management structures.However, blk_crypto_evict_key() is only called in contexts such as inodeeviction where failure is not an option. So actually the callerproceeds with freeing the blk_crypto_key regardless of the return valueof blk_crypto_evict_key().These two assumptions don't match, and the result is that there can be ause-after-free in blk_crypto_reprogram_all_keys() after one of theseerrors occurs. (Note, these errors *shouldn't* happen; we're justtalking about what happens if they do anyway.)Fix this by making blk_crypto_evict_key() unlink the key from thekeyslot management structures even on failure.Also improve some comments.

CVE-2024-46675 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:usb: dwc3: core: Prevent USB core invalid event buffer address accessThis commit addresses an issue where the USB core could access aninvalid event buffer address during runtime suspend, potentially causingSMMU faults and other memory issues in Exynos platforms. The problemarises from the following sequence. 1. In dwc3_gadget_suspend, there is a chance of a timeout when moving the USB core to the halt state after clearing the run/stop bit by software. 2. In dwc3_core_exit, the event buffer is cleared regardless of the USB core's status, which may lead to an SMMU faults and other memory issues. if the USB core tries to access the event buffer address.To prevent this hardware quirk on Exynos platforms, this commit ensuresthat the event buffer address is not cleared by software when the USBcore is active during runtime suspend by checking its status beforeclearing the buffer address.

CVE-2024-53680 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:ipvs: fix UB due to uninitialized stack access in ip_vs_protocol_init()Under certain kernel configurations when building with Clang/LLVM, thecompiler does not generate a return or jump as the terminatorinstruction for ip_vs_protocol_init(), triggering the following objtoolwarning during build time: vmlinux.o: warning: objtool: ip_vs_protocol_init() falls through to next function __initstub__kmod_ip_vs_rr__935_123_ip_vs_rr_init6()At runtime, this either causes an oops when trying to load the ipvsmodule or a boot-time panic if ipvs is built-in. This same issue hasbeen reported by the Intel kernel test robot previously.Digging deeper into both LLVM and the kernel code reveals this to be aundefined behavior problem. ip_vs_protocol_init() uses a on-stack bufferof 64 chars to store the registered protocol names and leaves ituninitialized after definition. The function calls strnlen() whenconcatenating protocol names into the buffer. With CONFIG_FORTIFY_SOURCEstrnlen() performs an extra step to check whether the last byte of theinput char buffer is a null character (commit 3009f891bb9f ("fortify:Allow strlen() and strnlen() to pass compile-time known lengths")).This, together with possibly other configurations, cause the followingIR to be generated: define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #5 section ".init.text" align 16 !kcfi_type !29 { %1 = alloca [64 x i8], align 16 ... 14: ; preds = %11 %15 = getelementptr inbounds i8, ptr %1, i64 63 %16 = load i8, ptr %15, align 1 %17 = tail call i1 @llvm.is.constant.i8(i8 %16) %18 = icmp eq i8 %16, 0 %19 = select i1 %17, i1 %18, i1 false br i1 %19, label %20, label %23 20: ; preds = %14 %21 = call i64 @strlen(ptr noundef nonnull dereferenceable(1) %1) #23 ... 23: ; preds = %14, %11, %20 %24 = call i64 @strnlen(ptr noundef nonnull dereferenceable(1) %1, i64 noundef 64) #24 ... }The above code calculates the address of the last char in the buffer(value %15) and then loads from it (value %16). Because the buffer isnever initialized, the LLVM GVN pass marks value %16 as undefined: %13 = getelementptr inbounds i8, ptr %1, i64 63 br i1 undef, label %14, label %17This gives later passes (SCCP, in particular) more DCE opportunities bypropagating the undef value further, and eventually removes everythingafter the load on the uninitialized stack location: define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #0 section ".init.text" align 16 !kcfi_type !11 { %1 = alloca [64 x i8], align 16 ... 12: ; preds = %11 %13 = getelementptr inbounds i8, ptr %1, i64 63 unreachable }In this way, the generated native code will just fall through to thenext function, as LLVM does not generate any code for the unreachable IRinstruction and leaves the function without a terminator.Zero the on-stack buffer to avoid this possible UB.

CVE-2025-38062 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:genirq/msi: Store the IOMMU IOVA directly in msi_desc instead of iommu_cookieThe IOMMU translation for MSI message addresses has been a 2-step process,separated in time: 1) iommu_dma_prepare_msi(): A cookie pointer containing the IOVA address is stored in the MSI descriptor when an MSI interrupt is allocated. 2) iommu_dma_compose_msi_msg(): this cookie pointer is used to compute a translated message address.This has an inherent lifetime problem for the pointer stored in the cookiethat must remain valid between the two steps. However, there is no lockingat the irq layer that helps protect the lifetime. Today, this works underthe assumption that the iommu domain is not changed while MSI interruptsbeing programmed. This is true for normal DMA API users within the kernel,as the iommu domain is attached before the driver is probed and cannot bechanged while a driver is attached.Classic VFIO type1 also prevented changing the iommu domain while VFIO wasrunning as it does not support changing the "container" after starting up.However, iommufd has improved this so that the iommu domain can be changedduring VFIO operation. This potentially allows userspace to directly raceVFIO_DEVICE_ATTACH_IOMMUFD_PT (which calls iommu_attach_group()) andVFIO_DEVICE_SET_IRQS (which calls into iommu_dma_compose_msi_msg()).This potentially causes both the cookie pointer and the unlocked call toiommu_get_domain_for_dev() on the MSI translation path to become UAFs.Fix the MSI cookie UAF by removing the cookie pointer. The translated IOVAaddress is already known during iommu_dma_prepare_msi() and cannot change.Thus, it can simply be stored as an integer in the MSI descriptor.The other UAF related to iommu_get_domain_for_dev() will be addressed inpatch "iommu: Make iommu_dma_prepare_msi() into a generic operation" byusing the IOMMU group mutex.

CVE-2025-38415 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:Squashfs: check return result of sb_min_blocksizeSyzkaller reports an "UBSAN: shift-out-of-bounds in squashfs_bio_read" bug.Syzkaller forks multiple processes which after mounting the Squashfsfilesystem, issues an ioctl("/dev/loop0", LOOP_SET_BLOCK_SIZE, 0x8000). Now if this ioctl occurs at the same time another process is in theprocess of mounting a Squashfs filesystem on /dev/loop0, the failureoccurs. When this happens the following code in squashfs_fill_super()fails.----msblk->devblksize = sb_min_blocksize(sb, SQUASHFS_DEVBLK_SIZE);msblk->devblksize_log2 = ffz(~msblk->devblksize);----sb_min_blocksize() returns 0, which means msblk->devblksize is set to 0.As a result, ffz(~msblk->devblksize) returns 64, and msblk->devblksize_log2is set to 64.This subsequently causes theUBSAN: shift-out-of-bounds in fs/squashfs/block.c:195:36shift exponent 64 is too large for 64-bit type 'u64' (aka'unsigned long long')This commit adds a check for a 0 return by sb_min_blocksize().

Description: In the Linux kernel, the following vulnerability has been resolved:NFC: nci: uart: Set tty->disc_data only in success pathSetting tty->disc_data before opening the NCI device means we need toclean it up on error paths. This also opens some short window if devicestarts sending data, even before NCIUARTSETDRIVER IOCTL succeeded(broken hardware?). Close the window by exposing tty->disc_data only onthe success path, when opening of the NCI device and try_module_get()succeeds.The code differs in error path in one aspect: tty->disc_data won't beever assigned thus NULL-ified. This however should not be relevantdifference, because of "tty->disc_data=NULL" in nci_uart_tty_open().

CVE-2025-38584 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:padata: Fix pd UAF once and for allThere is a race condition/UAF in padata_reorder that goes backto the initial commit. A reference count is taken at the startof the process in padata_do_parallel, and released at the end inpadata_serial_worker.This reference count is (and only is) required for padata_replaceto function correctly. If padata_replace is never called thenthere is no issue.In the function padata_reorder which serves as the core of padata,as soon as padata is added to queue->serial.list, and the associatedspin lock released, that padata may be processed and the referencecount on pd would go away.Fix this by getting the next padata before the squeue->serial lockis released.In order to make this possible, simplify padata_reorder by onlycalling it once the next padata arrives.

CVE-2025-39961 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:iommu/amd/pgtbl: Fix possible race while increase page table levelThe AMD IOMMU host page table implementation supports dynamic page table levels(up to 6 levels), starting with a 3-level configuration that expands based onIOVA address. The kernel maintains a root pointer and current page table levelto enable proper page table walks in alloc_pte()/fetch_pte() operations.The IOMMU IOVA allocator initially starts with 32-bit address and onces itsexhuasted it switches to 64-bit address (max address is determined basedon IOMMU and device DMA capability). To support larger IOVA, AMD IOMMUdriver increases page table level.But in unmap path (iommu_v1_unmap_pages()), fetch_pte() readspgtable->[root/mode] without lock. So its possible that in exteme corner case,when increase_address_space() is updating pgtable->[root/mode], fetch_pte()reads wrong page table level (pgtable->mode). It does compare the value withlevel encoded in page table and returns NULL. This will result isiommu_unmap ops to fail and upper layer may retry/log WARN_ON.CPU 0 CPU 1------ ------map pages unmap pagesalloc_pte() -> increase_address_space() iommu_v1_unmap_pages() -> fetch_pte() pgtable->root = pte (new root value) READ pgtable->[mode/root] Reads new root, old mode Updates mode (pgtable->mode += 1)Since Page table level updates are infrequent and already synchronized with aspinlock, implement seqcount to enable lock-free read operations on the read path.

Description: In the Linux kernel, the following vulnerability has been resolved:ethtool: Avoid overflowing userspace buffer on stats queryThe ethtool -S command operates across three ioctl calls:ETHTOOL_GSSET_INFO for the size, ETHTOOL_GSTRINGS for the names, andETHTOOL_GSTATS for the values.If the number of stats changes between these calls (e.g., due to devicereconfiguration), userspace's buffer allocation will be incorrect,potentially leading to buffer overflow.Drivers are generally expected to maintain stable stat counts, but somedrivers (e.g., mlx5, bnx2x, bna, ksz884x) use dynamic counters, makingthis scenario possible.Some drivers try to handle this internally:- bnad_get_ethtool_stats() returns early in case stats.n_stats is not equal to the driver's stats count.- micrel/ksz884x also makes sure not to write anything beyond stats.n_stats and overflow the buffer.However, both use stats.n_stats which is already assigned with the valuereturned from get_sset_count(), hence won't solve the issue describedhere.Change ethtool_get_strings(), ethtool_get_stats(),ethtool_get_phy_stats() to not return anything in case of a mismatchbetween userspace's size and get_sset_size(), to prevent bufferoverflow.The returned n_stats value will be equal to zero, to reflect thatnothing has been returned.This could result in one of two cases when using upstream ethtool,depending on when the size change is detected:1. When detected in ethtool_get_strings(): # ethtool -S eth2 no stats available2. When detected in get stats, all stats will be reported as zero.Both cases are presumably transient, and a subsequent ethtool callshould succeed.Other than the overflow avoidance, these two cases are very evident (nooutput/cleared stats), which is arguably better than presentingincorrect/shifted stats.I also considered returning an error instead of a "silent" response, butthat seems more destructive towards userspace apps.Notes:- This patch does not claim to fix the inherent race, it only makes sure that we do not overflow the userspace buffer, and makes for a more predictable behavior.- RTNL lock is held during each ioctl, the race window exists between the separate ioctl calls when the lock is released.- Userspace ethtool always fills stats.n_stats, but it is likely that these stats ioctls are implemented in other userspace applications which might not fill it. The added code checks that it's not zero, to prevent any regressions.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: target: iscsi: Fix use-after-free in iscsit_dec_session_usage_count()In iscsit_dec_session_usage_count(), the function calls complete() whileholding the sess->session_usage_lock. Similar to the connection usage countlogic, the waiter signaled by complete() (e.g., in the session releasepath) may wake up and free the iscsit_session structure immediately.This creates a race condition where the current thread may attempt toexecute spin_unlock_bh() on a session structure that has already beendeallocated, resulting in a KASAN slab-use-after-free.To resolve this, release the session_usage_lock before calling complete()to ensure all dereferences of the sess pointer are finished before thewaiter is allowed to proceed with deallocation.

Bitfield assignments generate byte read-modify-writeoperations (e.g. `orb $mask, addr` on x86_64), so updating one flag canrestore stale values of the others.A possible interleaving is: CPU1: load old byte (has_lease=1, on_list=1) CPU2: clear both flags (store 0) CPU1: RMW store (old | IS_OPEN) -> reintroduces cleared bitsTo avoid this class of races, convert these flags to separate boolfields.

CVE-2025-68736 Severity: Moderate CVSS3 score: 5.7

Description: In the Linux kernel, the following vulnerability has been resolved:landlock: Fix handling of disconnected directoriesDisconnected files or directories can appear when they are visible andopened from a bind mount, but have been renamed or moved from the sourceof the bind mount in a way that makes them inaccessible from the mountpoint (i.e. out of scope).Previously, access rights tied to files or directories opened through adisconnected directory were collected by walking the related hierarchydown to the root of the filesystem, without taking into account themount point because it couldn't be found. This could lead toinconsistent access results, potential access right widening, andhard-to-debug renames, especially since such paths cannot be printed.For a sandboxed task to create a disconnected directory, it needs tohave write access (i.e. FS_MAKE_REG, FS_REMOVE_FILE, and FS_REFER) tothe underlying source of the bind mount, and read access to the relatedmount point. Because a sandboxed task cannot acquire more accessrights than those defined by its Landlock domain, this could lead toinconsistent access rights due to missing permissions that should beinherited from the mount point hierarchy, while inheriting permissionsfrom the filesystem hierarchy hidden by this mount point instead.Landlock now handles files and directories opened from disconnecteddirectories by taking into account the filesystem hierarchy when themount point is not found in the hierarchy walk, and also always takinginto account the mount point from which these disconnected directorieswere opened. This ensures that a rename is not allowed if it wouldwiden access rights [1].The rationale is that, even if disconnected hierarchies might not bevisible or accessible to a sandboxed task, relying on the collectedaccess rights from them improves the guarantee that access rights willnot be widened during a rename because of the access right comparisonbetween the source and the destination (see LANDLOCK_ACCESS_FS_REFER).It may look like this would grant more access on disconnected files anddirectories, but the security policies are always enforced for all theevaluated hierarchies. This new behavior should be less surprising tousers and safer from an access control perspective.Remove a wrong WARN_ON_ONCE() canary in collect_domain_accesses() andfix the related comment.Because opened files have their access rights stored in the related filesecurity properties, there is no impact for disconnected or unlinkedfiles.

CVE-2024-35875 Severity: Moderate CVSS3 score: 5.6

Description: In the Linux kernel, the following vulnerability has been resolved:x86/coco: Require seeding RNG with RDRAND on CoCo systemsThere are few uses of CoCo that don't rely on working cryptography andhence a working RNG. Unfortunately, the CoCo threat model means that theVM host cannot be trusted and may actively work against guests toextract secrets or manipulate computation. Since a malicious host canmodify or observe nearly all inputs to guests, the only remaining sourceof entropy for CoCo guests is RDRAND.If RDRAND is broken -- due to CPU hardware fault -- the RNG as a wholeis meant to gracefully continue on gathering entropy from other sources,but since there aren't other sources on CoCo, this is catastrophic.This is mostly a concern at boot time when initially seeding the RNG, asafter that the consequences of a broken RDRAND are much moretheoretical.So, try at boot to seed the RNG using 256 bits of RDRAND output. If thisfails, panic(). This will also trigger if the system is booted withoutRDRAND, as RDRAND is essential for a safe CoCo boot.Add this deliberately to be "just a CoCo x86 driver feature" and notpart of the RNG itself. Many device drivers and platforms have somedesire to contribute something to the RNG, and add_device_randomness()is specifically meant for this purpose.Any driver can call it with seed data of any quality, or even garbagequality, and it can only possibly make the quality of the RNG better orhave no effect, but can never make it worse.Rather than trying to build something into the core of the RNG, considerthe particular CoCo issue just a CoCo issue, and therefore separate itall out into driver (well, arch/platform) code.

CVE-2026-3184 Severity: Moderate CVSS3 score: 5.6

Description: A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access.

CVE-2021-47214 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:hugetlb, userfaultfd: fix reservation restore on userfaultfd errorCurrently in the is_continue case in hugetlb_mcopy_atomic_pte(), if webail out using "goto out_release_unlock;" in the cases where idx >=size, or !huge_pte_none(), the code will detect that new_pagecache_page== false, and so call restore_reserve_on_error(). In this case I seerestore_reserve_on_error() delete the reservation, and the followingcall to remove_inode_hugepages() will increment h->resv_hugepagescausing a 100% reproducible leak.We should treat the is_continue case similar to adding a page into thepagecache and set new_pagecache_page to true, to indicate that there isno reservation to restore on the error path, and we need not callrestore_reserve_on_error(). Rename new_pagecache_page topage_in_pagecache to make that clear.

CVE-2021-47515 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:seg6: fix the iif in the IPv6 socket control blockWhen an IPv4 packet is received, the ip_rcv_core(...) sets the receivinginterface index into the IPv4 socket control block (v5.16-rc4,net/ipv4/ip_input.c line 510): IPCB(skb)->iif = skb->skb_iif;If that IPv4 packet is meant to be encapsulated in an outer IPv6+SRHheader, the seg6_do_srh_encap(...) performs the required encapsulation.In this case, the seg6_do_srh_encap function clears the IPv6 socket controlblock (v5.16-rc4 net/ipv6/seg6_iptunnel.c line 163): memset(IP6CB(skb), 0, sizeof(*IP6CB(skb)));The memset(...) was introduced in commit ef489749aae5 ("ipv6: sr: clearIP6CB(skb) on SRH ip4ip6 encapsulation") a long time ago (2019-01-29).Since the IPv6 socket control block and the IPv4 socket control block sharethe same memory area (skb->cb), the receiving interface index info is lost(IP6CB(skb)->iif is set to zero).As a side effect, that condition triggers a NULL pointer dereference ifcommit 0857d6f8c759 ("ipv6: When forwarding count rx stats on the orignetdev") is applied.To fix that issue, we set the IP6CB(skb)->iif with the index of thereceiving interface once again.

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: taprio: avoid disabling offload when it was never enabledIn an incredibly strange API design decision, qdisc->destroy() getscalled even if qdisc->init() never succeeded, not exclusively sincecommit 87b60cfacf9f ("net_sched: fix error recovery at qdisc creation"),but apparently also earlier (in the case of qdisc_create_dflt()).The taprio qdisc does not fully acknowledge this when it attempts fulloffload, because it starts off with q->flags = TAPRIO_FLAGS_INVALID intaprio_init(), then it replaces q->flags with TCA_TAPRIO_ATTR_FLAGSparsed from netlink (in taprio_change(), tail called from taprio_init()).But in taprio_destroy(), we call taprio_disable_offload(), and thisdetermines what to do based on FULL_OFFLOAD_IS_ENABLED(q->flags).But looking at the implementation of FULL_OFFLOAD_IS_ENABLED()(a bitwise check of bit 1 in q->flags), it is invalid to call this macroon q->flags when it contains TAPRIO_FLAGS_INVALID, because that is setto U32_MAX, and therefore FULL_OFFLOAD_IS_ENABLED() will return true onan invalid set of flags.As a result, it is possible to crash the kernel if user space forces anerror between setting q->flags = TAPRIO_FLAGS_INVALID, and the callingof taprio_enable_offload(). This is because drivers do not expect theoffload to be disabled when it was never enabled.The error that we force here is to attach taprio as a non-root qdisc,but instead as child of an mqprio root qdisc:$ tc qdisc add dev swp0 root handle 1: \ mqprio num_tc 8 map 0 1 2 3 4 5 6 7 \ queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 hw 0$ tc qdisc replace dev swp0 parent 1:1 \ taprio num_tc 8 map 0 1 2 3 4 5 6 7 \ queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 base-time 0 \ sched-entry S 0x7f 990000 sched-entry S 0x80 100000 \ flags 0x0 clockid CLOCK_TAIUnable to handle kernel paging request at virtual address fffffffffffffff8[fffffffffffffff8] pgd=0000000000000000, p4d=0000000000000000Internal error: Oops: 96000004 [#1] PREEMPT SMPCall trace: taprio_dump+0x27c/0x310 vsc9959_port_setup_tc+0x1f4/0x460 felix_port_setup_tc+0x24/0x3c dsa_slave_setup_tc+0x54/0x27c taprio_disable_offload.isra.0+0x58/0xe0 taprio_destroy+0x80/0x104 qdisc_create+0x240/0x470 tc_modify_qdisc+0x1fc/0x6b0 rtnetlink_rcv_msg+0x12c/0x390 netlink_rcv_skb+0x5c/0x130 rtnetlink_rcv+0x1c/0x2cFix this by keeping track of the operations we made, and undo theoffload only if we actually did it.I've added "bool offloaded" inside a 4 byte hole between "int clockid"and "atomic64_t picos_per_byte".

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix a memleak when uncloning an skb dst and its metadataWhen uncloning an skb dst and its associated metadata, a newdst+metadata is allocated and later replaces the old one in the skb.This is helpful to have a non-shared dst+metadata attached to a specificskb.The issue is the uncloned dst+metadata is initialized with a refcount of1, which is increased to 2 before attaching it to the skb. Whentun_dst_unclone returns, the dst+metadata is only referenced from asingle place (the skb) while its refcount is 2. Its refcount will neverdrop to 0 (when the skb is consumed), leading to a memory leak.Fix this by removing the call to dst_hold in tun_dst_unclone, as thedst+metadata refcount is already 1.

Description: In the Linux kernel, the following vulnerability has been resolved:swiotlb: fix info leak with DMA_FROM_DEVICEThe problem I'm addressing was discovered by the LTP test coveringcve-2018-1000204.A short description of what happens follows:1) The test case issues a command code 00 (TEST UNIT READY) via the SG_IO interface with: dxfer_len == 524288, dxdfer_dir == SG_DXFER_FROM_DEV and a corresponding dxferp. The peculiar thing about this is that TUR is not reading from the device.2) In sg_start_req() the invocation of blk_rq_map_user() effectively bounces the user-space buffer. As if the device was to transfer into it. Since commit a45b599ad808 ("scsi: sg: allocate with __GFP_ZERO in sg_build_indirect()") we make sure this first bounce buffer is allocated with GFP_ZERO.3) For the rest of the story we keep ignoring that we have a TUR, so the device won't touch the buffer we prepare as if the we had a DMA_FROM_DEVICE type of situation. My setup uses a virtio-scsi device and the buffer allocated by SG is mapped by the function virtqueue_add_split() which uses DMA_FROM_DEVICE for the "in" sgs (here scatter-gather and not scsi generics). This mapping involves bouncing via the swiotlb (we need swiotlb to do virtio in protected guest like s390 Secure Execution, or AMD SEV).4) When the SCSI TUR is done, we first copy back the content of the second (that is swiotlb) bounce buffer (which most likely contains some previous IO data), to the first bounce buffer, which contains all zeros. Then we copy back the content of the first bounce buffer to the user-space buffer.5) The test case detects that the buffer, which it zero-initialized, ain't all zeros and fails.One can argue that this is an swiotlb problem, because without swiotlbwe leak all zeros, and the swiotlb should be transparent in a sense thatit does not affect the outcome (if all other participants are wellbehaved).Copying the content of the original buffer into the swiotlb buffer isthe only way I can think of to make swiotlb transparent in suchscenarios. So let's do just that if in doubt, but allow the driverto tell us that the whole mapped buffer is going to be overwritten,in which case we can preserve the old behavior and avoid the performanceimpact of the extra bounce.

However if we had apending balance waiting to get the ->cleaner_mutex, and a snapshotdeletion was running, and then the box crashed, we would come up in astate where we have a half deleted snapshot.Again, in the normal case the snapshot deletion needs to complete beforerelocation can start, but in this case relocation could very well startbefore the snapshot deletion completes, as we simply add the root to thedead roots list and wait for the next time the cleaner runs to clean upthe snapshot.Fix this by setting a bit on the fs_info if we have any DEAD_ROOT's thathad a pending drop_progress key. If they do then we know we were in themiddle of the drop operation and set a flag on the fs_info. Thenbalance can wait until this flag is cleared to start up again.If there are DEAD_ROOT's that don't have a drop_progress set then we'resafe to start balance right away as we'll be properly protected by thecleaner_mutex.

It didn't keepus from continuing to use a buffer that we already had found.In this case we're searching the commit root to cache the block group,so we can start committing the transaction and switch the commit rootand then start writing. After the switch we can look up an extentbuffer that hasn't been written yet and start processing that blockgroup. Then we fail to write that block out and clear Uptodate on thepage, and then we start spewing these errors.Normally we're protected by the tree lock to a certain degree here. Ifwe read a block we have that block read locked, and we block the writerfrom locking the block before we submit it for the write. However thisisn't necessarily fool proof because the read could happen before we dothe submit_bio and after we locked and unlocked the extent buffer.Also in this particular case we have path->skip_locking set, so thatwon't save us here. We'll simply get a block that was valid when weread it, but became invalid while we were using it.What we really want is to catch the case where we've "read" a block butit's not marked Uptodate. On read we ClearPageError(), so if we're!Uptodate and !Error we know we didn't do the right thing for readingthe page.Fix this by checking !Uptodate && !Error, this way we will not complainif our buffer gets invalidated while we're using it, and we'll maintainthe spirit of the check which is to make sure we have a fully in-cacheblock while we're messing with it.

This change was madeby commit ce8ea7cc6eb313 ("btrfs: don't call btrfs_start_delalloc_rootsin flushoncommit"). After that change we started producing that warning,and every now and then a user reports this since the warning happens toooften, it spams dmesg/syslog, and a user is unsure if this reflects anyproblem that might compromise the filesystem's reliability.We can not just lock the sb->s_umount semaphore before callingwriteback_inodes_sb(), because that would at least deadlock withfilesystem freezing, since at fs/super.c:freeze_super() sync_filesystem()is called while we are holding that semaphore in write mode, and that cantrigger a transaction commit, resulting in a deadlock. It would alsotrigger the same type of deadlock in the unmount path. Possibly, it couldalso introduce some other locking dependencies that lockdep would report.To fix this call try_to_writeback_inodes_sb() instead ofwriteback_inodes_sb(), because that will try to read lock sb->s_umountand then will only call writeback_inodes_sb() if it was able to lock it.This is fine because the cases where it can't read lock sb->s_umountare during a filesystem unmount or during a filesystem freeze - in thosecases sb->s_umount is write locked and sync_filesystem() is called, whichcalls writeback_inodes_sb(). In other words, in all cases where we can'ttake a read lock on sb->s_umount, writeback is already being triggeredelsewhere.An alternative would be to call btrfs_start_delalloc_roots() with anumber of pages different from LONG_MAX, for example matching the numberof delalloc bytes we currently have, in ---truncated---

We must call ->destroy function of the object.nft_obj_destroy does this, but it also decrements the module refcount,but the update path doesn't increment it.To avoid special-casing the update object release, do module_get forthe update case too and release it via nft_obj_destroy().

Onlycasting max_entries to size_t is not enough, because for 32-bitsapplication on 64-bits kernel the size of read-only mmap regionalso could overflow size_t.So fixing it by casting the size of read-only mmap region into a __u64and checking whether or not there will be overflow during mmap.

CVE-2022-49049 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm/secretmem: fix panic when growing a memfd_secretWhen one tries to grow an existing memfd_secret with ftruncate, one getsa panic [1]. For example, doing the following reliably induces thepanic: fd = memfd_secret(); ftruncate(fd, 10); ptr = mmap(NULL, 10, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0); strcpy(ptr, "123456789"); munmap(ptr, 10); ftruncate(fd, 20);The basic reason for this is, when we grow with ftruncate, we call downinto simple_setattr, and then truncate_inode_pages_range, and eventuallywe try to zero part of the memory. The normal truncation code does thisvia the direct map (i.e., it calls page_address() and hands that tomemset()).For memfd_secret though, we specifically don't map our pages via thedirect map (i.e. we call set_direct_map_invalid_noflush() on everyfault). So the address returned by page_address() isn't useful, andwhen we try to memset() with it we panic.This patch avoids the panic by implementing a custom setattr formemfd_secret, which detects resizes specifically (setting the size forthe first time works just fine, since there are no existing pages to tryto zero), and rejects them with EINVAL.One could argue growing should be supported, but I think that willrequire a significantly more lengthy change. So, I propose a minimalfix for the benefit of stable kernels, and then perhaps to extendmemfd_secret to support growing in a separate patch.[1]: BUG: unable to handle page fault for address: ffffa0a889277028 #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page PGD afa01067 P4D afa01067 PUD 83f909067 PMD 83f8bf067 PTE 800ffffef6d88060 Oops: 0002 [#1] PREEMPT SMP DEBUG_PAGEALLOC PTI CPU: 0 PID: 281 Comm: repro Not tainted 5.17.0-dbg-DEV #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 RIP: 0010:memset_erms+0x9/0x10 Code: c1 e9 03 40 0f b6 f6 48 b8 01 01 01 01 01 01 01 01 48 0f af c6 f3 48 ab 89 d1 f3 aa 4c 89 c8 c3 90 49 89 f9 40 88 f0 48 89 d1 aa 4c 89 c8 c3 90 49 89 fa 40 0f b6 ce 48 b8 01 01 01 01 01 01 RSP: 0018:ffffb932c09afbf0 EFLAGS: 00010246 RAX: 0000000000000000 RBX: ffffda63c4249dc0 RCX: 0000000000000fd8 RDX: 0000000000000fd8 RSI: 0000000000000000 RDI: ffffa0a889277028 RBP: ffffb932c09afc00 R08: 0000000000001000 R09: ffffa0a889277028 R10: 0000000000020023 R11: 0000000000000000 R12: ffffda63c4249dc0 R13: ffffa0a890d70d98 R14: 0000000000000028 R15: 0000000000000fd8 FS: 00007f7294899580(0000) GS:ffffa0af9bc00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: ffffa0a889277028 CR3: 0000000107ef6006 CR4: 0000000000370ef0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: ? zero_user_segments+0x82/0x190 truncate_inode_partial_folio+0xd4/0x2a0 truncate_inode_pages_range+0x380/0x830 truncate_setsize+0x63/0x80 simple_setattr+0x37/0x60 notify_change+0x3d8/0x4d0 do_sys_ftruncate+0x162/0x1d0 __x64_sys_ftruncate+0x1c/0x20 do_syscall_64+0x44/0xa0 entry_SYSCALL_64_after_hwframe+0x44/0xae Modules linked in: xhci_pci xhci_hcd virtio_net net_failover failover virtio_blk virtio_balloon uhci_hcd ohci_pci ohci_hcd evdev ehci_pci ehci_hcd 9pnet_virtio 9p netfs 9pnet CR2: ffffa0a889277028[lkp@intel.com: secretmem_iops can be static][axelrasmussen@google.com: return EINVAL]

CVE-2022-49075 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix qgroup reserve overflow the qgroup limitWe use extent_changeset->bytes_changed in qgroup_reserve_data() to recordhow many bytes we set for EXTENT_QGROUP_RESERVED state. Currently thebytes_changed is set as "unsigned int", and it will overflow if we try tofallocate a range larger than 4GiB. The result is we reserve less bytesand eventually break the qgroup limit.Unlike regular buffered/direct write, which we use one changeset foreach ordered extent, which can never be larger than 256M. Forfallocate, we use one changeset for the whole range, thus it no longerrespects the 256M per extent limit, and caused the problem.The following example test script reproduces the problem: $ cat qgroup-overflow.sh #!/bin/bash DEV=/dev/sdj MNT=/mnt/sdj mkfs.btrfs -f $DEV mount $DEV $MNT # Set qgroup limit to 2GiB. btrfs quota enable $MNT btrfs qgroup limit 2G $MNT # Try to fallocate a 3GiB file.

Description: In the Linux kernel, the following vulnerability has been resolved:mlxsw: spectrum: Guard against invalid local portsWhen processing events generated by the device's firmware, the driverprotects itself from events reported for non-existent local ports, butnot for the CPU port (local port 0), which exists, but does not have allthe fields as any local port.This can result in a NULL pointer dereference when trying access'struct mlxsw_sp_port' fields which are not initialized for CPU port.Commit 63b08b1f6834 ("mlxsw: spectrum: Protect driver from buggy firmware")already handled such issue by bailing early when processing a PUDE eventreported for the CPU port.Generalize the approach by moving the check to a common function andmaking use of it in all relevant places.

CVE-2022-49149 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: Fix call timer start racing with call destructionThe rxrpc_call struct has a timer used to handle various timed eventsrelating to a call. This timer can get started from the packet inputroutines that are run in softirq mode with just the RCU read lock held.Unfortunately, because only the RCU read lock is held - and neither ref orother lock is taken - the call can start getting destroyed at the same timea packet comes in addressed to that call. This causes the timer - whichwas already stopped - to get restarted. Later, the timer dispatch code maythen oops if the timer got deallocated first.Fix this by trying to take a ref on the rxrpc_call struct and, ifsuccessful, passing that ref along to the timer. If the timer was alreadyrunning, the ref is discarded.The timer completion routine can then pass the ref along to the call's workitem when it queues it. If the timer or work item where alreadyqueued/running, the extra ref is discarded.

CVE-2022-49167 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: do not double complete bio on errors during compressed readsI hit some weird panics while fixing up the error handling frombtrfs_lookup_bio_sums(). Turns out the compression path will completethe bio we use if we set up any of the compression bios and then returnan error, and then btrfs_submit_data_bio() will also call bio_endio() onthe bio.Fix this by making btrfs_submit_compressed_read() responsible forcalling bio_endio() on the bio if there are any errors. Currently itwas only doing it if we created the compression bios, otherwise it wasdepending on btrfs_submit_data_bio() to do the right thing. Thiscreates the above problem, so fix up btrfs_submit_compressed_read() toalways call bio_endio() in case of an error, and then simply return frombtrfs_submit_data_bio() if we had to callbtrfs_submit_compressed_read().

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: do not clean up repair bio if submit failsThe submit helper will always run bio_endio() on the bio if it fails tosubmit, so cleaning up the bio just leads to a variety of use-after-freeand NULL pointer dereference bugs because we race with the endiofunction that is cleaning up the bio. Instead just return BLK_STS_OK asthe repair function has to continue to process the rest of the pages,and the endio for the repair bio will do the appropriate cleanup for thepage that it was given.

Description: In the Linux kernel, the following vulnerability has been resolved:xsk: Fix race at socket teardownFix a race in the xsk socket teardown code that can lead to a NULL pointerdereference splat. The current xsk unbind code in xsk_unbind_dev() starts bysetting xs->state to XSK_UNBOUND, sets xs->dev to NULL and then waits for anyNAPI processing to terminate using synchronize_net().

First, setting xs->dev to NULLbefore waiting for all users to stop using the socket is not correct. Theentry to the data plane functions xsk_poll(), xsk_sendmsg(), and xsk_recvmsg()are all guarded by a test that xs->state is in the state XSK_BOUND and if not,it returns right away. But one process might have passed this test but stillhave not gotten to the point in which it uses xs->dev in the code. In thisinterim, a second process executing xsk_unbind_dev() might have set xs->dev toNULL which will lead to a crash for the first process. The solution here isjust to get rid of this NULL assignment since it is not used anymore. Beforecommit 42fddcc7c64b ("xsk: use state member for socket synchronization"),xs->dev was the gatekeeper to admit processes into the data plane functions,but it was replaced with the state variable xs->state in the aforementionedcommit.The second problem is that synchronize_net() does not wait for any process inxsk_poll(), xsk_sendmsg(), or xsk_recvmsg() to complete, which means that thestate they rely on might be cleaned up prematurely. This can happen when thenotifier gets called (at driver unload for example) as it uses xsk_unbind_dev().Solve this by extending the RCU critical region from just the ndo_xsk_wakeupto the whole functions mentioned above, so that both the test of xs->state ==XSK_BOUND and the last use of any member of xs is covered by the RCU criticalsection. This will guarantee that when synchronize_net() completes, there willbe no processes left executing xsk_poll(), xsk_sendmsg(), or xsk_recvmsg() andstate can be cleaned up safely. Note that we need to drop the RCU lock for theskb xmit path as it uses functions that might sleep. Due to this, we have toretest the xs->state after we grab the mutex that protects the skb xmit codefrom, among a number of things, an xsk_unbind_dev() being executed from thenotifier at the same time.

CVE-2022-49219 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:vfio/pci: fix memory leak during D3hot to D0 transitionIf 'vfio_pci_core_device::needs_pm_restore' is set (PCI device doesnot have No_Soft_Reset bit set in its PMCSR config register), thenthe current PCI state will be saved locally in'vfio_pci_core_device::pm_save' during D0->D3hot transition and samewill be restored back during D3hot->D0 transition.For saving the PCI state locally, pci_store_saved_state() is beingused and the pci_load_and_free_saved_state() will free the allocatedmemory.But for reset related IOCTLs, vfio driver calls PCI reset-relatedAPI's which will internally change the PCI power state back to D0. So,when the guest resumes, then it will get the current state as D0 and itwill skip the call to vfio_pci_set_power_state() for changing thepower state to D0 explicitly. In this case, the memory pointed by'pm_save' will never be freed. In a malicious sequence, the state changingto D3hot followed by VFIO_DEVICE_RESET/VFIO_DEVICE_PCI_HOT_RESET can berun in a loop and it can cause an OOM situation.This patch frees the earlier allocated memory first before overwriting'pm_save' to prevent the mentioned memory leak.

CVE-2022-49340 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ip_gre: test csum_start instead of transport headerGRE with TUNNEL_CSUM will apply local checksum offload onCHECKSUM_PARTIAL packets.ipgre_xmit must validate csum_start after an optional skb_pull,else lco_csum may trigger an overflow. The original check was if (csum && skb_checksum_start(skb) < skb->data) return -EINVAL;This had false positives when skb_checksum_start is undefined:when ip_summed is not CHECKSUM_PARTIAL. A discussed refinementwas straightforward if (csum && skb->ip_summed == CHECKSUM_PARTIAL && skb_checksum_start(skb) < skb->data) return -EINVAL;But was eventually revised more thoroughly:- restrict the check to the only branch where needed, in an uncommon GRE path that uses header_ops and calls skb_pull.- test skb_transport_header, which is set along with csum_start in skb_partial_csum_set in the normal header_ops datapath.Turns out skbs can arrive in this branch without the transportheader set, e.g., through BPF redirection.Revise the check back to check csum_start directly, and only ifCHECKSUM_PARTIAL. Do leave the check in the updated location.Check field regardless of whether TUNNEL_CSUM is configured.

Description: In the Linux kernel, the following vulnerability has been resolved:nvdimm: Fix firmware activation deadlock scenariosLockdep reports the following deadlock scenarios for CXL root devicepower-management, device_prepare(), operations, and device_shutdown()operations for 'nd_region' devices: Chain exists of: &nvdimm_region_key --> &nvdimm_bus->reconfig_mutex --> system_transition_mutex Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(system_transition_mutex); lock(&nvdimm_bus->reconfig_mutex); lock(system_transition_mutex); lock(&nvdimm_region_key); Chain exists of: &cxl_nvdimm_bridge_key --> acpi_scan_lock --> &cxl_root_key Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&cxl_root_key); lock(acpi_scan_lock); lock(&cxl_root_key); lock(&cxl_nvdimm_bridge_key);These stem from holding nvdimm_bus_lock() over hibernate_quiet_exec()which walks the entire system device topology taking device_lock() alongthe way. The nvdimm_bus_lock() is protecting against unregistration,multiple simultaneous ops callers, and preventing activate_show() fromracing activate_store(). For the first 2, the lock is redundant.Unregistration already flushes all ops users, and sysfs already preventsmultiple threads to be active in an ops handler at the same time. Forthe last userspace should already be waiting for its lastactivate_store() to complete, and does not need activate_show() to flushthe write side, so this lock usage can be deleted in these attributes.

CVE-2022-49450 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: Fix listen() setting the bar too high for the prealloc ringsAF_RXRPC's listen() handler lets you set the backlog up to 32 (if you bumpup the sysctl), but whilst the preallocation circular buffers have 32 slotsin them, one of them has to be a dead slot because we're using CIRC_CNT().This means that listen(rxrpc_sock, 32) will cause an oops when the socketis closed because rxrpc_service_prealloc_one() allocated one too many callsand rxrpc_discard_prealloc() won't then be able to get rid of them becauseit'll think the ring is empty. rxrpc_release_calls_on_socket() then triesto abort them, but oopses because call->peer isn't yet set.Fix this by setting the maximum backlog to RXRPC_BACKLOG_MAX - 1 to matchthe ring capacity.

CVE-2022-49530 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amd/pm: fix double free in si_parse_power_table()In function si_parse_power_table(), array adev->pm.dpm.ps and its memberis allocated. If the allocation of each member fails, the array itselfis freed and returned with an error code. However, the array is laterfreed again in si_dpm_fini() function which is called when the functionreturns an error.This leads to potential double free of the array adev->pm.dpm.ps, aswell as leak of its array members, since the members are not freed inthe allocation function and the array is not nulled when freed.In addition adev->pm.dpm.num_ps, which keeps track of the allocatedarray member, is not updated until the member allocation issuccessfully finished, this could also lead to either use after free,or uninitialized variable access in si_dpm_fini().Fix this by postponing the free of the array until si_dpm_fini() andincrement adev->pm.dpm.num_ps everytime the array member is allocated.

When copying the SSIDs into thescan_req_params structure in the ath11k_mac_op_hw_scan route, it canoverwrite the extraie pointer.Firmware supports 16 ssid * 4 bssid, for each ssid 4 bssid combo proberequest will be sent, so totally 64 probe requests supported.

Since pages which haven'tyet been locked can concurrently migrate off the zspage page list whilelock_zspage() churns away, lock_zspage() can suffer from a few differentlethal races.It can lock a page which no longer belongs to the zspage and unsafelydereference page_private(), it can unsafely dereference a torn pointer tothe next page (since there's a data race), and it can observe a spuriousNULL pointer to the next page and thus not lock all of the zspage's pages(since a single page migration will reconstruct the entire page list, andcreate_page_chain() unconditionally zeroes out each list pointer in theprocess).Fix the races by using migrate_read_lock() in lock_zspage() to synchronizewith page migration.

Description: In the Linux kernel, the following vulnerability has been resolved:net: dsa: qca8k: reset cpu port on MTU changeIt was discovered that the Documentation lacks of a fundamental detailon how to correctly change the MAX_FRAME_SIZE of the switch.In fact if the MAX_FRAME_SIZE is changed while the cpu port is on, theswitch panics and cease to send any packet. This cause the mgmt ethernetsystem to not receive any packet (the slow fallback still works) andmakes the device not reachable. To recover from this a switch reset isrequired.To correctly handle this, turn off the cpu ports before changing theMAX_FRAME_SIZE and turn on again after the value is applied.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix request_sock leak in sk lookup helpersA customer reported a request_socket leak in a Calico cloud environment. Wefound that a BPF program was doing a socket lookup with takes a refcnt onthe socket and that it was finding the request_socket but returning the parentLISTEN socket via sk_to_full_sk() without decrementing the child request socket1st, resulting in request_sock slab object leak. This patch retains theexisting behaviour of returning full socks to the caller but it also decrementsthe child request_socket if one is present before doing so to prevent the leak.Thanks to Curtis Taylor for all the help in diagnosing and testing this. Andthanks to Antoine Tenart for the reproducer and patch input.v2 of this patch contains, refactor as per Daniel Borkmann's suggestions tovalidate RCU flags on the listen socket so that it balances with bpf_sk_release()and update comments as per Martin KaFai Lau's suggestion. One small change toDaniels suggestion, put "sk = sk2" under "if (sk2 != sk)" to avoid an extrainstruction.

I'm guessing that thiswas done to allow creating psocks for non-inet sockets.Unfortunately the destruction path for psock includes the ULPunwind, so we need to fail the sk_psock_init() itself.Otherwise if ULP is already present we'll notice that later,and call tcp_update_ulp() with the sk_proto of the ULPitself, which will most likely result in the ULP loopingits callbacks.

This can lead to very little useful info fordebugging.This patch will:- Add extra info for error reporting Including: * logical bytenr * num_bytes * type * action * ref_mod- Replace the btrfs_debug() with btrfs_err()- Move the error reporting into run_one_delayed_ref() This is to avoid use-after-free, the @node can be freed in the caller.This error should only be triggered at most once.As if run_one_delayed_ref() failed, we trigger the error message, thencausing the call chain to error out:btrfs_run_delayed_refs()`- btrfs_run_delayed_refs() `- btrfs_run_delayed_refs_for_head() `- run_one_delayed_ref()And we will abort the current transaction in btrfs_run_delayed_refs().If we have to run delayed refs for the abort transaction,run_one_delayed_ref() will just cleanup the refs and do nothing, thus nonew error messages would be output.

CVE-2022-49762 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ntfs: check overflow when iterating ATTR_RECORDsKernel iterates over ATTR_RECORDs in mft record in ntfs_attr_find(). Because the ATTR_RECORDs are next to each other, kernel can get the nextATTR_RECORD from end address of current ATTR_RECORD, through currentATTR_RECORD length field.The problem is that during iteration, when kernel calculates the endaddress of current ATTR_RECORD, kernel may trigger an integer overflow bugin executing `a = (ATTR_RECORD*)((u8*)a + le32_to_cpu(a->length))`. Thismay wrap, leading to a forever iteration on 32bit systems.This patch solves it by adding some checks on calculating end addressof current ATTR_RECORD during iteration.

Description: In the Linux kernel, the following vulnerability has been resolved:net: dsa: don't leak tagger-owned storage on switch driver unbindIn the initial commit dc452a471dba ("net: dsa: introduce tagger-ownedstorage for private and shared data"), we had a call totag_ops->disconnect(dst) issued from dsa_tree_free(), which is called attree teardown time.There were problems with connecting to a switch tree as a whole, so thisgot reworked to connecting to individual switches within the tree. Inthis process, tag_ops->disconnect(ds) was made to be called only fromswitch.c (cross-chip notifiers emitted as a result of dynamic tag protochanges), but the normal driver teardown code path wasn't replaced withanything.Solve this problem by adding a function that does the opposite ofdsa_switch_setup_tag_protocol(), which is called from the equivalentspot in dsa_switch_teardown(). The positioning here also ensures that wewon't have any use-after-free in tagging protocol (*rcv) ops, since theteardown sequence is as follows:dsa_tree_teardown-> dsa_tree_teardown_master -> dsa_master_teardown -> unsets master->dsa_ptr, making no further packets match the ETH_P_XDSA packet type handler-> dsa_tree_teardown_ports -> dsa_port_teardown -> dsa_slave_destroy -> unregisters DSA net devices, there is even a synchronize_net() in unregister_netdevice_many()-> dsa_tree_teardown_switches -> dsa_switch_teardown -> dsa_switch_teardown_tag_protocol -> finally frees the tagger-owned storage

Description: In the Linux kernel, the following vulnerability has been resolved:hugetlbfs: don't delete error page from pagecacheThis change is very similar to the change that was made for shmem [1], andit solves the same problem but for HugeTLBFS instead.Currently, when poison is found in a HugeTLB page, the page is removedfrom the page cache. That means that attempting to map or read thathugepage in the future will result in a new hugepage being allocatedinstead of notifying the user that the page was poisoned. As [1] states,this is effectively memory corruption.The fix is to leave the page in the page cache. If the user attempts touse a poisoned HugeTLB page with a syscall, the syscall will fail withEIO, the same error code that shmem uses. For attempts to map the page,the thread will get a BUS_MCEERR_AR SIGBUS.[1]: commit a76054266661 ("mm: shmem: don't truncate page if memory failure happens")

CVE-2022-49872 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: gso: fix panic on frag_list with mixed head alloc typesSince commit 3dcbdb134f32 ("net: gso: Fix skb_segment splat whensplitting gso_size mangled skb having linear-headed frag_list"), it isallowed to change gso_size of a GRO packet. However, that commit assumesthat "checking the first list_skb member suffices; i.e if either of thelist_skb members have non head_frag head, then the first one has too".It turns out this assumption does not hold. We've seen BUG_ON being hitin skb_segment when skbs on the frag_list had differing head_frag withthe vmxnet3 driver. This happens because __netdev_alloc_skb and__napi_alloc_skb can return a skb that is page backed or kmalloceddepending on the requested size. As the result, the last small skb inthe GRO packet can be kmalloced.There are three different locations where this can be fixed:(1) We could check head_frag in GRO and not allow GROing skbs with different head_frag. However, that would lead to performance regression on normal forward paths with unmodified gso_size, where !head_frag in the last packet is not a problem.(2) Set a flag in bpf_skb_net_grow and bpf_skb_net_shrink indicating that NETIF_F_SG is undesirable. That would need to eat a bit in sk_buff. Furthermore, that flag can be unset when all skbs on the frag_list are page backed. To retain good performance, bpf_skb_net_grow/shrink would have to walk the frag_list.(3) Walk the frag_list in skb_segment when determining whether NETIF_F_SG should be cleared. This of course slows things down.This patch implements (3). To limit the performance impact inskb_segment, the list is walked only for skbs with SKB_GSO_DODGY setthat have gso_size changed. Normal paths thus will not hit it.We could check only the last skb but since we need to walk the wholelist anyway, let's stay on the safe side.

'n' here is the number of items in this block, which inthis case was 1, but we had 2 REMOVE_WHILE_FREEING operations.The actual root cause of this was that we were replaying operations fora block that shouldn't have been replayed. Consider the followingsequence of events1. We have an already modified root, and we do a btrfs_get_tree_mod_seq().2. We begin removing items from this root, triggering KEY_REPLACE for it's child slots.3. We remove one of the 2 children this root node points to, thus triggering the root node promotion of the remaining child, and freeing this node.4. We modify a new root, and re-allocate the above node to the root node of this other root.The tree mod log looks something like this logical 0 op KEY_REPLACE (slot 1) seq 2 logical 0 op KEY_REMOVE (slot 1) seq 3 logical 0 op KEY_REMOVE_WHILE_FREEING (slot 0) seq 4 logical 4096 op LOG_ROOT_REPLACE (old logical 0) seq 5 logical 8192 op KEY_REMOVE_WHILE_FREEING (slot 1) seq 6 logical 8192 op KEY_REMOVE_WHILE_FREEING (slot 0) seq 7 logical 0 op LOG_ROOT_REPLACE (old logical 8192) seq 8>From here the bug is triggered by the following steps1. Call btrfs_get_old_root() on the new_root.2. We call tree_mod_log_oldest_root(btrfs_root_node(new_root)), which is currently logical 0.3. tree_mod_log_oldest_root() calls tree_mod_log_search_oldest(), which gives us the KEY_REPLACE seq 2, and since that's not a LOG_ROOT_REPLACE we incorrectly believe that we don't have an old root, because we expect that the most recent change should be a LOG_ROOT_REPLACE.4. Back in tree_mod_log_oldest_root() we don't have a LOG_ROOT_REPLACE, so we don't set old_root, we simply use our e---truncated---

CVE-2022-49899 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fscrypt: stop using keyrings subsystem for fscrypt_master_keyThe approach of fs/crypto/ internally managing the fscrypt_master_keystructs as the payloads of "struct key" objects contained in a"struct key" keyring has outlived its usefulness. The original idea wasto simplify the code by reusing code from the keyrings subsystem.However, several issues have arisen that can't easily be resolved:- When a master key struct is destroyed, blk_crypto_evict_key() must be called on any per-mode keys embedded in it. (This started being the case when inline encryption support was added.) Yet, the keyrings subsystem can arbitrarily delay the destruction of keys, even past the time the filesystem was unmounted. Therefore, currently there is no easy way to call blk_crypto_evict_key() when a master key is destroyed. Currently, this is worked around by holding an extra reference to the filesystem's request_queue(s). But it was overlooked that the request_queue reference is *not* guaranteed to pin the corresponding blk_crypto_profile too; for device-mapper devices that support inline crypto, it doesn't. This can cause a use-after-free.- When the last inode that was using an incompletely-removed master key is evicted, the master key removal is completed by removing the key struct from the keyring. Currently this is done via key_invalidate(). Yet, key_invalidate() takes the key semaphore. This can deadlock when called from the shrinker, since in fscrypt_ioctl_add_key(), memory is allocated with GFP_KERNEL under the same semaphore.- More generally, the fact that the keyrings subsystem can arbitrarily delay the destruction of keys (via garbage collection delay, or via random processes getting temporary key references) is undesirable, as it means we can't strictly guarantee that all secrets are ever wiped.- Doing the master key lookups via the keyrings subsystem results in the key_permission LSM hook being called. fscrypt doesn't want this, as all access control for encrypted files is designed to happen via the files themselves, like any other files. The workaround which SELinux users are using is to change their SELinux policy to grant key search access to all domains. This works, but it is an odd extra step that shouldn't really have to be done.The fix for all these issues is to change the implementation to what Ishould have done originally: don't use the keyrings subsystem to keeptrack of the filesystem's fscrypt_master_key structs. Instead, juststore them in a regular kernel data structure, and rework the referencecounting, locking, and lifetime accordingly. Retain support forRCU-mode key lookups by using a hash table. Replace fscrypt_sb_free()with fscrypt_sb_delete(), which releases the keys synchronously and runsa bit earlier during unmount, so that block devices are still available.A side effect of this patch is that neither the master keys themselvesnor the filesystem keyrings will be listed in /proc/keys anymore.("Master key users" and the master key users keyrings will still belisted.) However, this was mostly an implementation detail, and it wasintended just for debugging purposes. I don't know of anyone using it.This patch does *not* change how "master key users" (->mk_users) works;that still uses the keyrings subsystem. That is still needed for keyquotas, and changing that isn't necessary to solve the issues listedabove. If we decide to change that too, it would be a separate patch.I've marked this as fixing the original commit that added the fscryptkeyring, but as noted above the most important issue that this patchfixes wasn't introduced until the addition of inline encryption support.

Since theywere not yet added to the refs ulist and prelim_release() does not freethe lists, on error the caller can only free the lists attached to therefs that were added to the refs ulist, all the remaining refs get theirinode lists never freed, therefore leaking their memory.Fix this by having prelim_release() always free any attached inode listto each ref found in the rbtree, and have find_parent_nodes() set theref's inode list to NULL once it transfers ownership of the inode listto a ref added to the refs ulist passed to find_parent_nodes().

CVE-2022-49935 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:dma-buf/dma-resv: check if the new fence is really laterPreviously when we added a fence to a dma_resv object we alwaysassumed the the newer than all the existing fences.With Jason's work to add an UAPI to explicit export/import that's notnecessary the case any more. So without this check we would allowuserspace to force the kernel into an use after free error.Since the change is very small and defensive it's probably a goodidea to backport this to stable kernels as well just in case othersare using the dma_resv object in the same way.

CVE-2022-49998 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: Fix locking in rxrpc's sendmsgFix three bugs in the rxrpc's sendmsg implementation: (1) rxrpc_new_client_call() should release the socket lock when returning an error from rxrpc_get_call_slot(). (2) rxrpc_wait_for_tx_window_intr() will return without the call mutex held in the event that we're interrupted by a signal whilst waiting for tx space on the socket or relocking the call mutex afterwards. Fix this by: (a) moving the unlock/lock of the call mutex up to rxrpc_send_data() such that the lock is not held around all of rxrpc_wait_for_tx_window*() and (b) indicating to higher callers whether we're return with the lock dropped. Note that this means recvmsg() will not block on this call whilst we're waiting. (3) After dropping and regaining the call mutex, rxrpc_send_data() needs to go and recheck the state of the tx_pending buffer and the tx_total_len check in case we raced with another sendmsg() on the same call.Thinking on this some more, it might make sense to have different locks forsendmsg() and recvmsg(). There's probably no need to make recvmsg() waitfor sendmsg(). It does mean that recvmsg() can return MSG_EOR indicatingthat a call is dead before a sendmsg() to that call returns - but that cancurrently happen anyway.Without fix (2), something like the following can be induced: WARNING: bad unlock balance detected! 5.16.0-rc6-syzkaller #0 Not tainted ------------------------------------- syz-executor011/3597 is trying to release lock (&call->user_mutex) at: [] rxrpc_do_sendmsg+0xc13/0x1350 net/rxrpc/sendmsg.c:748 but there are no more locks to release! other info that might help us debug this: no locks held by syz-executor011/3597. ...

CVE-2022-50000 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: flowtable: fix stuck flows on cleanup due to pending workTo clear the flow table on flow table free, the following sequencenormally happens in order: 1) gc_step work is stopped to disable any further stats/del requests. 2) All flow table entries are set to teardown state. 3) Run gc_step which will queue HW del work for each flow table entry. 4) Waiting for the above del work to finish (flush). 5) Run gc_step again, deleting all entries from the flow table. 6) Flow table is freed.But if a flow table entry already has pending HW stats or HW add workstep 3 will not queue HW del work (it will be skipped), step 4 will waitfor the pending add/stats to finish, and step 5 will queue HW del workwhich might execute after freeing of the flow table.To fix the above, this patch flushes the pending work, then it sets theteardown flag to all flows in the flowtable and it forces a garbagecollector run to queue work to remove the flows from hardware, then itflushes this new pending work and (finally) it forces another garbagecollector run to remove the entry from the software flowtable.Stack trace:[47773.882335] BUG: KASAN: use-after-free in down_read+0x99/0x460[47773.883634] Write of size 8 at addr ffff888103b45aa8 by task kworker/u20:6/543704[47773.885634] CPU: 3 PID: 543704 Comm: kworker/u20:6 Not tainted 5.12.0-rc7+ #2[47773.886745] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009)[47773.888438] Workqueue: nf_ft_offload_del flow_offload_work_handler [nf_flow_table][47773.889727] Call Trace:[47773.890214] dump_stack+0xbb/0x107[47773.890818] print_address_description.constprop.0+0x18/0x140[47773.892990] kasan_report.cold+0x7c/0xd8[47773.894459] kasan_check_range+0x145/0x1a0[47773.895174] down_read+0x99/0x460[47773.899706] nf_flow_offload_tuple+0x24f/0x3c0 [nf_flow_table][47773.907137] flow_offload_work_handler+0x72d/0xbe0 [nf_flow_table][47773.913372] process_one_work+0x8ac/0x14e0[47773.921325][47773.921325] Allocated by task 592159:[47773.922031] kasan_save_stack+0x1b/0x40[47773.922730] __kasan_kmalloc+0x7a/0x90[47773.923411] tcf_ct_flow_table_get+0x3cb/0x1230 [act_ct][47773.924363] tcf_ct_init+0x71c/0x1156 [act_ct][47773.925207] tcf_action_init_1+0x45b/0x700[47773.925987] tcf_action_init+0x453/0x6b0[47773.926692] tcf_exts_validate+0x3d0/0x600[47773.927419] fl_change+0x757/0x4a51 [cls_flower][47773.928227] tc_new_tfilter+0x89a/0x2070[47773.936652][47773.936652] Freed by task 543704:[47773.937303] kasan_save_stack+0x1b/0x40[47773.938039] kasan_set_track+0x1c/0x30[47773.938731] kasan_set_free_info+0x20/0x30[47773.939467] __kasan_slab_free+0xe7/0x120[47773.940194] slab_free_freelist_hook+0x86/0x190[47773.941038] kfree+0xce/0x3a0[47773.941644] tcf_ct_flow_table_cleanup_workOriginal patch description and stack trace by Paul Blakey.

CVE-2022-50002 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5: LAG, fix logic over MLX5_LAG_FLAG_NDEVS_READYOnly set MLX5_LAG_FLAG_NDEVS_READY if both netdevices are registered.Doing so guarantees that both ldev->pf[MLX5_LAG_P0].dev andldev->pf[MLX5_LAG_P1].dev have valid pointers whenMLX5_LAG_FLAG_NDEVS_READY is set.The core issue is asymmetry in setting MLX5_LAG_FLAG_NDEVS_READY andclearing it. Setting it is done wrongly when bothldev->pf[MLX5_LAG_P0].dev and ldev->pf[MLX5_LAG_P1].dev are set;clearing it is done right when either of ldev->pf[i].netdev is cleared.Consider the following scenario:1. PF0 loads and sets ldev->pf[MLX5_LAG_P0].dev to a valid pointer2. PF1 loads and sets both ldev->pf[MLX5_LAG_P1].dev and ldev->pf[MLX5_LAG_P1].netdev with valid pointers. This results in MLX5_LAG_FLAG_NDEVS_READY is set.3. PF0 is unloaded before setting dev->pf[MLX5_LAG_P0].netdev. MLX5_LAG_FLAG_NDEVS_READY remains set.Further execution of mlx5_do_bond() will result in null pointerdereference when calling mlx5_lag_is_multipath()This patch fixes the following call trace actually encountered:[ 1293.475195] BUG: kernel NULL pointer dereference, address: 00000000000009a8[ 1293.478756] #PF: supervisor read access in kernel mode[ 1293.481320] #PF: error_code(0x0000) - not-present page[ 1293.483686] PGD 0 P4D 0[ 1293.484434] Oops: 0000 [#1] SMP PTI[ 1293.485377] CPU: 1 PID: 23690 Comm: kworker/u16:2 Not tainted 5.18.0-rc5_for_upstream_min_debug_2022_05_05_10_13 #1[ 1293.488039] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014[ 1293.490836] Workqueue: mlx5_lag mlx5_do_bond_work [mlx5_core][ 1293.492448] RIP: 0010:mlx5_lag_is_multipath+0x5/0x50 [mlx5_core][ 1293.494044] Code: e8 70 40 ff e0 48 8b 14 24 48 83 05 5c 1a 1b 00 01 e9 19 ff ff ff 48 83 05 47 1a 1b 00 01 eb d7 0f 1f 44 00 00 0f 1f 44 00 00 <48> 8b 87 a8 09 00 00 48 85 c0 74 26 48 83 05 a7 1b 1b 00 01 41 b8[ 1293.498673] RSP: 0018:ffff88811b2fbe40 EFLAGS: 00010202[ 1293.500152] RAX: ffff88818a94e1c0 RBX: ffff888165eca6c0 RCX: 0000000000000000[ 1293.501841] RDX: 0000000000000001 RSI: ffff88818a94e1c0 RDI: 0000000000000000[ 1293.503585] RBP: 0000000000000000 R08: ffff888119886740 R09: ffff888165eca73c[ 1293.505286] R10: 0000000000000018 R11: 0000000000000018 R12: ffff88818a94e1c0[ 1293.506979] R13: ffff888112729800 R14: 0000000000000000 R15: ffff888112729858[ 1293.508753] FS: 0000000000000000(0000) GS:ffff88852cc40000(0000) knlGS:0000000000000000[ 1293.510782] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 1293.512265] CR2: 00000000000009a8 CR3: 00000001032d4002 CR4: 0000000000370ea0[ 1293.514001] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 1293.515806] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400

CVE-2022-50003 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ice: xsk: prohibit usage of non-balanced queue idFix the following scenario:1. ethtool -L $IFACE rx 8 tx 962. xdpsock -q 10 -t -zAbove refers to a case where user would like to attach XSK socket intxonly mode at a queue id that does not have a corresponding Rx queue.At this moment ice's XSK logic is tightly bound to act on a "queue pair",e.g. both Tx and Rx queues at a given queue id are disabled/enabled andboth of them will get XSK pool assigned, which is broken for the presentedqueue configuration. This results in the splat included at the bottom,which is basically an OOB access to Rx ring array.To fix this, allow using the ids only in scope of "combined" queuesreported by ethtool. However, logic should be rewritten to allow suchconfigurations later on, which would end up as a complete rewrite of thecontrol path, so let us go with this temporary fix.[420160.558008] BUG: kernel NULL pointer dereference, address: 0000000000000082[420160.566359] #PF: supervisor read access in kernel mode[420160.572657] #PF: error_code(0x0000) - not-present page[420160.579002] PGD 0 P4D 0[420160.582756] Oops: 0000 [#1] PREEMPT SMP NOPTI[420160.588396] CPU: 10 PID: 21232 Comm: xdpsock Tainted: G OE 5.19.0-rc7+ #10[420160.597893] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019[420160.609894] RIP: 0010:ice_xsk_pool_setup+0x44/0x7d0 [ice][420160.616968] Code: f3 48 83 ec 40 48 8b 4f 20 48 8b 3f 65 48 8b 04 25 28 00 00 00 48 89 44 24 38 31 c0 48 8d 04 ed 00 00 00 00 48 01 c1 48 8b 11 <0f> b7 92 82 00 00 00 48 85 d2 0f 84 2d 75 00 00 48 8d 72 ff 48 85[420160.639421] RSP: 0018:ffffc9002d2afd48 EFLAGS: 00010282[420160.646650] RAX: 0000000000000050 RBX: ffff88811d8bdd00 RCX: ffff888112c14ff8[420160.655893] RDX: 0000000000000000 RSI: ffff88811d8bdd00 RDI: ffff888109861000[420160.665166] RBP: 000000000000000a R08: 000000000000000a R09: 0000000000000000[420160.674493] R10: 000000000000889f R11: 0000000000000000 R12: 000000000000000a[420160.683833] R13: 000000000000000a R14: 0000000000000000 R15: ffff888117611828[420160.693211] FS: 00007fa869fc1f80(0000) GS:ffff8897e0880000(0000) knlGS:0000000000000000[420160.703645] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[420160.711783] CR2: 0000000000000082 CR3: 00000001d076c001 CR4: 00000000007706e0[420160.721399] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[420160.731045] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[420160.740707] PKRU: 55555554[420160.745960] Call Trace:[420160.750962] [420160.755597] ? kmalloc_large_node+0x79/0x90[420160.762703] ? __kmalloc_node+0x3f5/0x4b0[420160.769341] xp_assign_dev+0xfd/0x210[420160.775661] ? shmem_file_read_iter+0x29a/0x420[420160.782896] xsk_bind+0x152/0x490[420160.788943] __sys_bind+0xd0/0x100[420160.795097] ? exit_to_user_mode_prepare+0x20/0x120[420160.802801] __x64_sys_bind+0x16/0x20[420160.809298] do_syscall_64+0x38/0x90[420160.815741] entry_SYSCALL_64_after_hwframe+0x63/0xcd[420160.823731] RIP: 0033:0x7fa86a0dd2fb[420160.830264] Code: c3 66 0f 1f 44 00 00 48 8b 15 69 8b 0c 00 f7 d8 64 89 02 b8 ff ff ff ff eb bc 0f 1f 44 00 00 f3 0f 1e fa b8 31 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d 3d 8b 0c 00 f7 d8 64 89 01 48[420160.855410] RSP: 002b:00007ffc1146f618 EFLAGS: 00000246 ORIG_RAX: 0000000000000031[420160.866366] RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007fa86a0dd2fb[420160.876957] RDX: 0000000000000010 RSI: 00007ffc1146f680 RDI: 0000000000000003[420160.887604] RBP: 000055d7113a0520 R08: 00007fa868fb8000 R09: 0000000080000000[420160.898293] R10: 0000000000008001 R11: 0000000000000246 R12: 000055d7113a04e0[420160.909038] R13: 000055d7113a0320 R14: 000000000000000a R15: 0000000000000000[420160.919817] [420160.925659] Modules linked in: ice(OE) af_packet binfmt_misc---truncated---

When thefetching process of the object `pols[1]` fails, the function simplyreturns 0, forgetting to decrement the reference count of `pols[0]`,which is incremented earlier by either xfrm_sk_policy_lookup() orxfrm_policy_lookup(). This may result in memory leaks.Fix it by decreasing the reference count of `pols[0]` in that path.

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix potential refcount leak in ndisc_router_discovery()The issue happens on specific paths in the function. After both theobject `rt` and `neigh` are grabbed successfully, when `lifetime` isnonzero but the metric needs change, the function just deletes theroute and set `rt` to NULL. Then, it may try grabbing `rt` and `neigh`again if above conditions hold. The function simply overwrite `neigh`if succeeds or returns if fails, without decreasing the referencecount of previous `neigh`. This may result in memory leaks.Fix it by decrementing the reference count of `neigh` in place.

CVE-2022-50069 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:BPF: Fix potential bad pointer dereference in bpf_sys_bpf()The bpf_sys_bpf() helper function allows an eBPF program to load anothereBPF program from within the kernel. In this case the argument unionbpf_attr pointer (as well as the insns and license pointers inside) is akernel address instead of a userspace address (which is the case of ausual bpf() syscall). To make the memory copying process in the syscallwork in both cases, bpfptr_t was introduced to wrap around the pointerand distinguish its origin. Specifically, when copying memory contentsfrom a bpfptr_t, a copy_from_user() is performed in case of a userspaceaddress and a memcpy() is performed for a kernel address.This can lead to problems because the in-kernel pointer is never checkedfor validity. The problem happens when an eBPF syscall program tries tocall bpf_sys_bpf() to load a program but provides a bad insns pointer --say 0xdeadbeef -- in the bpf_attr union. The helper calls __sys_bpf()which would then call bpf_prog_load() to load the program.bpf_prog_load() is responsible for copying the eBPF instructions to thenewly allocated memory for the program; it creates a kernel bpfptr_t forinsns and invokes copy_from_bpfptr(). Internally, all bpfptr_toperations are backed by the corresponding sockptr_t operations, whichperforms direct memcpy() on kernel pointers for copy_from/strncpy_fromoperations. Therefore, the code is always happy to dereference the badpointer to trigger a un-handle-able page fault and in turn an oops.However, this is not supposed to happen because at that point the eBPFprogram is already verified and should not cause a memory error.Sample KASAN trace:[ 25.685056][ T228] ==================================================================[ 25.685680][ T228] BUG: KASAN: user-memory-access in copy_from_bpfptr+0x21/0x30[ 25.686210][ T228] Read of size 80 at addr 00000000deadbeef by task poc/228[ 25.686732][ T228][ 25.686893][ T228] CPU: 3 PID: 228 Comm: poc Not tainted 5.19.0-rc7 #7[ 25.687375][ T228] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS d55cb5a 04/01/2014[ 25.687991][ T228] Call Trace:[ 25.688223][ T228] [ 25.688429][ T228] dump_stack_lvl+0x73/0x9e[ 25.688747][ T228] print_report+0xea/0x200[ 25.689061][ T228] ? copy_from_bpfptr+0x21/0x30[ 25.689401][ T228] ? _printk+0x54/0x6e[ 25.689693][ T228] ? _raw_spin_lock_irqsave+0x70/0xd0[ 25.690071][ T228] ? copy_from_bpfptr+0x21/0x30[ 25.690412][ T228] kasan_report+0xb5/0xe0[ 25.690716][ T228] ? copy_from_bpfptr+0x21/0x30[ 25.691059][ T228] kasan_check_range+0x2bd/0x2e0[ 25.691405][ T228] ? copy_from_bpfptr+0x21/0x30[ 25.691734][ T228] memcpy+0x25/0x60[ 25.692000][ T228] copy_from_bpfptr+0x21/0x30[ 25.692328][ T228] bpf_prog_load+0x604/0x9e0[ 25.692653][ T228] ? cap_capable+0xb4/0xe0[ 25.692956][ T228] ? security_capable+0x4f/0x70[ 25.693324][ T228] __sys_bpf+0x3af/0x580[ 25.693635][ T228] bpf_sys_bpf+0x45/0x240[ 25.693937][ T228] bpf_prog_f0ec79a5a3caca46_bpf_func1+0xa2/0xbd[ 25.694394][ T228] bpf_prog_run_pin_on_cpu+0x2f/0xb0[ 25.694756][ T228] bpf_prog_test_run_syscall+0x146/0x1c0[ 25.695144][ T228] bpf_prog_test_run+0x172/0x190[ 25.695487][ T228] __sys_bpf+0x2c5/0x580[ 25.695776][ T228] __x64_sys_bpf+0x3a/0x50[ 25.696084][ T228] do_syscall_64+0x60/0x90[ 25.696393][ T228] ? fpregs_assert_state_consistent+0x50/0x60[ 25.696815][ T228] ? exit_to_user_mode_prepare+0x36/0xa0[ 25.697202][ T228] ? syscall_exit_to_user_mode+0x20/0x40[ 25.697586][ T228] ? do_syscall_64+0x6e/0x90[ 25.697899][ T228] entry_SYSCALL_64_after_hwframe+0x63/0xcd[ 25.698312][ T228] RIP: 0033:0x7f6d543fb759[ 25.698624][ T228] Code: 08 5b 89 e8 5d c3 66 2e 0f 1f 84 00 00 00 00 00 90 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d ---truncated---

CVE-2022-50086 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:block: don't allow the same type rq_qos add more than onceIn our test of iocost, we encountered some list add/del corruptions ofinner_walk list in ioc_timer_fn.The reason can be described as follows:cpu 0 cpu 1ioc_qos_write ioc_qos_writeioc = q_to_ioc(queue);if (!ioc) { ioc = kzalloc(); ioc = q_to_ioc(queue); if (!ioc) { ioc = kzalloc(); ... rq_qos_add(q, rqos); } ... rq_qos_add(q, rqos); ...}When the io.cost.qos file is written by two cpus concurrently, rq_qos maybe added to one disk twice. In that case, there will be two iocs enabledand running on one disk. They own different iocgs on their active list. Inthe ioc_timer_fn function, because of the iocgs from two iocs have thesame root iocg, the root iocg's walk_list may be overwritten by each otherand this leads to list add/del corruptions in building or destroying theinner_walk list.And so far, the blk-rq-qos framework works in case that one instance forone type rq_qos per queue by default. This patch make this explicit andalso fix the crash above.

When btrfs can allocate bytes for one partof the split regions but fails for the other region (e.g. because of-ENOSPC), we return the error leaving the pages in the succeeded regionslocked. Technically, this occurs only when @unlock == 0. Otherwise, weunlock the pages in an allocated region after creating an orderedextent.Considering the callers of cow_file_range(unlock=0) won't write outthe pages, we can unlock the pages on error exit fromcow_file_range(). So, we can ensure all the pages except @locked_pageare unlocked on error case.In summary, cow_file_range now behaves like this:- page_started == 1 (return value) - All the pages are unlocked. IO is started.- unlock == 1 - All the pages except @locked_page are unlocked in any case- unlock == 0 - On success, all the pages are locked for writing out them - On failure, all the pages except @locked_page are unlocked

CVE-2022-50090 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: replace BTRFS_MAX_EXTENT_SIZE with fs_info->max_extent_sizeOn zoned filesystem, data write out is limited by max_zone_append_size,and a large ordered extent is split according the size of a bio. OTOH,the number of extents to be written is calculated usingBTRFS_MAX_EXTENT_SIZE, and that estimated number is used to reserve themetadata bytes to update and/or create the metadata items.The metadata reservation is done at e.g, btrfs_buffered_write() and thenreleased according to the estimation changes. Thus, if the number of extentincreases massively, the reserved metadata can run out.The increase of the number of extents easily occurs on zoned filesystemif BTRFS_MAX_EXTENT_SIZE > max_zone_append_size. And, it causes thefollowing warning on a small RAM environment with disabling metadataover-commit (in the following patch).[75721.498492] ------------[ cut here ]------------[75721.505624] BTRFS: block rsv 1 returned -28[75721.512230] WARNING: CPU: 24 PID: 2327559 at fs/btrfs/block-rsv.c:537 btrfs_use_block_rsv+0x560/0x760 [btrfs][75721.581854] CPU: 24 PID: 2327559 Comm: kworker/u64:10 Kdump: loaded Tainted: G W 5.18.0-rc2-BTRFS-ZNS+ #109[75721.597200] Hardware name: Supermicro Super Server/H12SSL-NT, BIOS 2.0 02/22/2021[75721.607310] Workqueue: btrfs-endio-write btrfs_work_helper [btrfs][75721.616209] RIP: 0010:btrfs_use_block_rsv+0x560/0x760 [btrfs][75721.646649] RSP: 0018:ffffc9000fbdf3e0 EFLAGS: 00010286[75721.654126] RAX: 0000000000000000 RBX: 0000000000004000 RCX: 0000000000000000[75721.663524] RDX: 0000000000000004 RSI: 0000000000000008 RDI: fffff52001f7be6e[75721.672921] RBP: ffffc9000fbdf420 R08: 0000000000000001 R09: ffff889f8d1fc6c7[75721.682493] R10: ffffed13f1a3f8d8 R11: 0000000000000001 R12: ffff88980a3c0e28[75721.692284] R13: ffff889b66590000 R14: ffff88980a3c0e40 R15: ffff88980a3c0e8a[75721.701878] FS: 0000000000000000(0000) GS:ffff889f8d000000(0000) knlGS:0000000000000000[75721.712601] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[75721.720726] CR2: 000055d12e05c018 CR3: 0000800193594000 CR4: 0000000000350ee0[75721.730499] Call Trace:[75721.735166] [75721.739886] btrfs_alloc_tree_block+0x1e1/0x1100 [btrfs][75721.747545] ? btrfs_alloc_logged_file_extent+0x550/0x550 [btrfs][75721.756145] ? btrfs_get_32+0xea/0x2d0 [btrfs][75721.762852] ? btrfs_get_32+0xea/0x2d0 [btrfs][75721.769520] ? push_leaf_left+0x420/0x620 [btrfs][75721.776431] ? memcpy+0x4e/0x60[75721.781931] split_leaf+0x433/0x12d0 [btrfs][75721.788392] ? btrfs_get_token_32+0x580/0x580 [btrfs][75721.795636] ? push_for_double_split.isra.0+0x420/0x420 [btrfs][75721.803759] ? leaf_space_used+0x15d/0x1a0 [btrfs][75721.811156] btrfs_search_slot+0x1bc3/0x2790 [btrfs][75721.818300] ? lock_downgrade+0x7c0/0x7c0[75721.824411] ? free_extent_buffer.part.0+0x107/0x200 [btrfs][75721.832456] ? split_leaf+0x12d0/0x12d0 [btrfs][75721.839149] ? free_extent_buffer.part.0+0x14f/0x200 [btrfs][75721.846945] ? free_extent_buffer+0x13/0x20 [btrfs][75721.853960] ? btrfs_release_path+0x4b/0x190 [btrfs][75721.861429] btrfs_csum_file_blocks+0x85c/0x1500 [btrfs][75721.869313] ? rcu_read_lock_sched_held+0x16/0x80[75721.876085] ? lock_release+0x552/0xf80[75721.881957] ? btrfs_del_csums+0x8c0/0x8c0 [btrfs][75721.888886] ? __kasan_check_write+0x14/0x20[75721.895152] ? do_raw_read_unlock+0x44/0x80[75721.901323] ? _raw_write_lock_irq+0x60/0x80[75721.907983] ? btrfs_global_root+0xb9/0xe0 [btrfs][75721.915166] ? btrfs_csum_root+0x12b/0x180 [btrfs][75721.921918] ? btrfs_get_global_root+0x820/0x820 [btrfs][75721.929166] ? _raw_write_unlock+0x23/0x40[75721.935116] ? unpin_extent_cache+0x1e3/0x390 [btrfs][75721.942041] btrfs_finish_ordered_io.isra.0+0xa0c/0x1dc0 [btrfs][75721.949906] ? try_to_wake_up+0x30/0x14a0[75721.955700] ? btrfs_unlink_subvol+0xda0/0xda0 [btrfs][75721.962661] ? rcu---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:locking/csd_lock: Change csdlock_debug from early_param to __setupThe csdlock_debug kernel-boot parameter is parsed by theearly_param() function csdlock_debug(). If set, csdlock_debug()invokes static_branch_enable() to enable csd_lock_wait feature, whichtriggers a panic on arm64 for kernels built with CONFIG_SPARSEMEM=y andCONFIG_SPARSEMEM_VMEMMAP=n.With CONFIG_SPARSEMEM_VMEMMAP=n, __nr_to_section is called instatic_key_enable() and returns NULL, resulting in a NULL dereferencebecause mem_section is initialized only later in sparse_init().This is also a problem for powerpc because early_param() functionsare invoked earlier than jump_label_init(), also resulting instatic_key_enable() failures. These failures cause the warning "statickey 'xxx' used before call to jump_label_init()".Thus, early_param is too early for csd_lock_wait to runstatic_branch_enable(), so changes it to __setup to fix these.

The sequenceabove is a corner case which keeps the bus operational but without adriver bound.While trying to solve this kernel oopses, it became clear that theexisting SoundWire bus does not deal well with the unbind case.Commit 528be501b7d4a ("soundwire: sdw_slave: add probe_complete structure and new fields")added a 'probed' status variable and a 'probe_complete'struct completion. This status is however not reset on remove andlikewise the 'probe complete' is not re-initialized, so thebind/unbind/bind test cases would fail. The timeout used before the'update_status' callback was also a bad idea in hindsight, thereshould really be no timing assumption as to if and when a driver isbound to a device.An initial draft was based on device_lock() and device_unlock() wastested. This proved too complicated, with deadlocks created during thesuspend-resume sequences, which also use the same device_lock/unlock()as the bind/unbind sequences. On a CometLake device, a bad DSDT/BIOScaused spurious resumes and the use of device_lock() caused hangsduring suspend. After multiple weeks or testing and painfulreverse-engineering of deadlocks on different devices, we looked foralternatives that did not interfere with the device core.A bus notifier was used successfully to keep track of DRIVER_BOUND andDRIVER_UNBIND events. This solved the bind-unbind-bind case in tests,but it can still be defeated with a theoretical corner case where thememory is freed by a .remove while the callback is in use. Thenotifier only helps make sure the driver callbacks are valid, but notthat the memory allocated in probe remains valid while the callbacksare invoked.This patch suggests the introduction of a new 'sdw_dev_lock' mutexprotecting probe/remove and all driver callbacks. Since this mutex is'local' to SoundWire only, it does not interfere with existing locksand does not create deadlocks. In addition, this patch removes the'probe_complete' completion, instead we directly invoke the'update_status' from the probe routine. That removes any sort oftiming dependency and a much better support for the device/drivermodel, the driver could be bound before the bus started, or eons afterthe bus started and the hardware would be properly initialized in allcases.BugLink: https://github.com/thesofproject/linux/is---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:of: check previous kernel's ima-kexec-buffer against memory boundsPresently ima_get_kexec_buffer() doesn't check if the previous kernel'sima-kexec-buffer lies outside the addressable memory range. This can resultin a kernel panic if the new kernel is booted with 'mem=X' arg and theima-kexec-buffer was allocated beyond that range by the previous kernel.The panic is usually of the form below:$ sudo kexec --initrd initrd vmlinux --append='mem=16G' BUG: Unable to handle kernel data access on read at 0xc000c01fff7f0000 Faulting instruction address: 0xc000000000837974 Oops: Kernel access of bad area, sig: 11 [#1] NIP [c000000000837974] ima_restore_measurement_list+0x94/0x6c0 LR [c00000000083b55c] ima_load_kexec_buffer+0xac/0x160 Call Trace: [c00000000371fa80] [c00000000083b55c] ima_load_kexec_buffer+0xac/0x160 [c00000000371fb00] [c0000000020512c4] ima_init+0x80/0x108 [c00000000371fb70] [c0000000020514dc] init_ima+0x4c/0x120 [c00000000371fbf0] [c000000000012240] do_one_initcall+0x60/0x2c0 [c00000000371fcc0] [c000000002004ad0] kernel_init_freeable+0x344/0x3ec [c00000000371fda0] [c0000000000128a4] kernel_init+0x34/0x1b0 [c00000000371fe10] [c00000000000ce64] ret_from_kernel_thread+0x5c/0x64 Instruction dump: f92100b8 f92100c0 90e10090 910100a0 4182050c 282a0017 3bc00000 40810330 7c0802a6 fb610198 7c9b2378 f80101d0 2c090001 40820614 e9240010 ---[ end trace 0000000000000000 ]---Fix this issue by checking returned PFN range of previous kernel'sima-kexec-buffer with page_is_ram() to ensure correct memory bounds.

CVE-2022-50177 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:rcutorture: Fix ksoftirqd boosting timing and iterationThe RCU priority boosting can fail in two situations:1) If (nr_cpus= > maxcpus=), which means if the total number of CPUsis higher than those brought online at boot, then torture_onoff() maylater bring up CPUs that weren't online on boot. Now since rcutortureinitialization only boosts the ksoftirqds of the CPUs that have beenset online on boot, the CPUs later set online by torture_onoff won'tbenefit from the boost, making RCU priority boosting fail.2) The ksoftirqd kthreads are boosted after the creation ofrcu_torture_boost() kthreads, which opens a window large enough for thesercu_torture_boost() kthreads to wait (despite running at FIFO priority)for ksoftirqds that are still running at SCHED_NORMAL priority.The issues can trigger for example with: ./kvm.sh --configs TREE01 --kconfig "CONFIG_RCU_BOOST=y" [ 34.968561] rcu-torture: !!!

CVE-2022-50214 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:coresight: Clear the connection field properlycoresight devices track their connections (output connections) andhold a reference to the fwnode. When a device goes away, we walk throughthe devices on the coresight bus and make sure that the referencesare dropped. This happens both ways: a) For all output connections from the device, drop the reference to the target device via coresight_release_platform_data()b) Iterate over all the devices on the coresight bus and drop the reference to fwnode if *this* device is the target of the output connection, via coresight_remove_conns()->coresight_remove_match().However, the coresight_remove_match() doesn't clear the fwnode field,after dropping the reference, this causes use-after-free andadditional refcount drops on the fwnode.e.g., if we have two devices, A and B, with a connection, A -> B.If we remove B first, B would clear the reference on B, from Avia coresight_remove_match(). But when A is removed, it still hasa connection with fwnode still pointing to B. Thus it tries to dropsthe reference in coresight_release_platform_data(), raising the bellslike :[ 91.990153] ------------[ cut here ]------------[ 91.990163] refcount_t: addition on 0; use-after-free.[ 91.990212] WARNING: CPU: 0 PID: 461 at lib/refcount.c:25 refcount_warn_saturate+0xa0/0x144[ 91.990260] Modules linked in: coresight_funnel coresight_replicator coresight_etm4x(-) crct10dif_ce coresight ip_tables x_tables ipv6 [last unloaded: coresight_cpu_debug][ 91.990398] CPU: 0 PID: 461 Comm: rmmod Tainted: G W T 5.19.0-rc2+ #53[ 91.990418] Hardware name: ARM LTD ARM Juno Development Platform/ARM Juno Development Platform, BIOS EDK II Feb 1 2019[ 91.990434] pstate: 600000c5 (nZCv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--)[ 91.990454] pc : refcount_warn_saturate+0xa0/0x144[ 91.990476] lr : refcount_warn_saturate+0xa0/0x144[ 91.990496] sp : ffff80000c843640[ 91.990509] x29: ffff80000c843640 x28: ffff800009957c28 x27: ffff80000c8439a8[ 91.990560] x26: ffff00097eff1990 x25: ffff8000092b6ad8 x24: ffff00097eff19a8[ 91.990610] x23: ffff80000c8439a8 x22: 0000000000000000 x21: ffff80000c8439c2[ 91.990659] x20: 0000000000000000 x19: ffff00097eff1a10 x18: ffff80000ab99c40[ 91.990708] x17: 0000000000000000 x16: 0000000000000000 x15: ffff80000abf6fa0[ 91.990756] x14: 000000000000001d x13: 0a2e656572662d72 x12: 657466612d657375[ 91.990805] x11: 203b30206e6f206e x10: 6f69746964646120 x9 : ffff8000081aba28[ 91.990854] x8 : 206e6f206e6f6974 x7 : 69646461203a745f x6 : 746e756f63666572[ 91.990903] x5 : ffff00097648ec58 x4 : 0000000000000000 x3 : 0000000000000027[ 91.990952] x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff00080260ba00[ 91.991000] Call trace:[ 91.991012] refcount_warn_saturate+0xa0/0x144[ 91.991034] kobject_get+0xac/0xb0[ 91.991055] of_node_get+0x2c/0x40[ 91.991076] of_fwnode_get+0x40/0x60[ 91.991094] fwnode_handle_get+0x3c/0x60[ 91.991116] fwnode_get_nth_parent+0xf4/0x110[ 91.991137] fwnode_full_name_string+0x48/0xc0[ 91.991158] device_node_string+0x41c/0x530[ 91.991178] pointer+0x320/0x3ec[ 91.991198] vsnprintf+0x23c/0x750[ 91.991217] vprintk_store+0x104/0x4b0[ 91.991238] vprintk_emit+0x8c/0x360[ 91.991257] vprintk_default+0x44/0x50[ 91.991276] vprintk+0xcc/0xf0[ 91.991295] _printk+0x68/0x90[ 91.991315] of_node_release+0x13c/0x14c[ 91.991334] kobject_put+0x98/0x114[ 91.991354] of_node_put+0x24/0x34[ 91.991372] of_fwnode_put+0x40/0x5c[ 91.991390] fwnode_handle_put+0x38/0x50[ 91.991411] coresight_release_platform_data+0x74/0xb0 [coresight][ 91.991472] coresight_unregister+0x64/0xcc [coresight][ 91.991525] etm4_remove_dev+0x64/0x78 [coresight_etm4x][ 91.991563] etm4_remove_amba+0x1c/0x2c [coresight_etm4x][ 91.991598] amba_remove+0x3c/0x19c---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix KASAN use-after-free Read in compute_effective_progsSyzbot found a Use After Free bug in compute_effective_progs().The reproducer creates a number of BPF links, and causes a faultinjected alloc to fail, while calling bpf_link_detach on them.Link detach triggers the link to be freed by bpf_link_free(),which calls __cgroup_bpf_detach() and update_effective_progs().If the memory allocation in this function fails, the function restoresthe pointer to the bpf_cgroup_link on the cgroup list, but the memorygets freed just after it returns. After this, every subsequent call toupdate_effective_progs() causes this already deallocated pointer to bedereferenced in prog_list_length(), and triggers KASAN UAF error.To fix this issue don't preserve the pointer to the prog or link in thelist, but remove it and replace it with a dummy prog without shrinkingthe table. The subsequent call to __cgroup_bpf_detach() or__cgroup_bpf_detach() will correct it.

Description: In the Linux kernel, the following vulnerability has been resolved:arm64: set UXN on swapper page tables[ This issue was fixed upstream by accident in c3cee924bd85 ("arm64: head: cover entire kernel image in initial ID map") as part of a large refactoring of the arm64 boot flow. This simple fix is therefore preferred for -stable backporting ]On a system that implements FEAT_EPAN, read/write access to the idmapis denied because UXN is not set on the swapper PTEs. As a result,idmap_kpti_install_ng_mappings panics the kernel when accessing__idmap_kpti_flag. Fix it by setting UXN on these PTEs.

CVE-2022-50293 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: do not BUG_ON() on ENOMEM when dropping extent items for a rangeIf we get -ENOMEM while dropping file extent items in a given range, atbtrfs_drop_extents(), due to failure to allocate memory when attempting toincrement the reference count for an extent or drop the reference count,we handle it with a BUG_ON(). This is excessive, instead we can simplyabort the transaction and return the error to the caller. In fact mostcallers of btrfs_drop_extents(), directly or indirectly, already abortthe transaction if btrfs_drop_extents() returns any error.Also, we already have error paths at btrfs_drop_extents() that may return-ENOMEM and in those cases we abort the transaction, like for exampleanything that changes the b+tree may return -ENOMEM due to a failure toallocate a new extent buffer when COWing an existing extent buffer, suchas a call to btrfs_duplicate_item() for example.So replace the BUG_ON() calls with proper logic to abort the transactionand return the error.

Then `r` is assigned with `cp->perfect + handle`,which is newly allocated. So condition `old_r && old_r != r` istrue in this situation, and kernel uses tcindex_filter_result_init()to clear the old filter result, without destroyingits tcf_exts structure * If `old_r` is retrieved from `p->h`, then `p->perfect` is NULLaccording to the tcindex_lookup(). Considering that `cp->h`is directly copied from `p->h` and `p->perfect` is NULL,`r` is assigned with `tcindex_lookup(cp, handle)`, whose valueshould be the same as `old_r`, so condition `old_r && old_r != r`is false in this situation, kernel ignores usingtcindex_filter_result_init() to clear the old filter result.So only when `old_r` is retrieved from `p->perfect` does kernel usetcindex_filter_result_init() to clear the old filter result, whichtriggers the above memory leak.Considering that there already exists a tc_filter_wq workqueueto destroy the old tcindex_d---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:cxl: fix possible null-ptr-deref in cxl_guest_init_afu|adapter()If device_register() fails in cxl_register_afu|adapter(), the deviceis not added, device_unregister() can not be called in the error path,otherwise it will cause a null-ptr-deref because of removing not addeddevice.As comment of device_register() says, it should use put_device() to giveup the reference in the error path. So split device_unregister() intodevice_del() and put_device(), then goes to put dev when register fails.

CVE-2022-50550 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:blk-iolatency: Fix memory leak on add_disk() failuresWhen a gendisk is successfully initialized but add_disk() fails such as whena loop device has invalid number of minor device numbers specified,blkcg_init_disk() is called during init and then blkcg_exit_disk() duringerror handling. Unfortunately, iolatency gets initialized in the former butdoesn't get cleaned up in the latter.This is because, in non-error cases, the cleanup is performed bydel_gendisk() calling rq_qos_exit(), the assumption being that rq_qospolicies, iolatency being one of them, can only be activated once the diskis fully registered and visible. That assumption is true for wbt and iocost,but not so for iolatency as it gets initialized before add_disk() is called.It is desirable to lazy-init rq_qos policies because they are optionalfeatures and add to hot path overhead once initialized - each IO has to walkall the registered rq_qos policies. So, we want to switch iolatency to lazyinit too. However, that's a bigger change. As a fix for the immediateproblem, let's just add an extra call to rq_qos_exit() in blkcg_exit_disk().This is safe because duplicate calls to rq_qos_exit() become noop's.

To ensure the lsock is not released during thetipc_topsrv_accept(), move sock_release() after tipc_topsrv_work_stop()where it's waiting until the tipc_topsrv_accept worker to be done.Note that sk_callback_lock is used to protect sk->sk_user_data instead ofsrv->listener, and it should check srv in tipc_topsrv_listener_data_ready()instead. This also ensures that no more tipc_topsrv_accept worker will bestarted after tipc_conn_close() is called in tipc_topsrv_stop() where itsets sk->sk_user_data to null.

Check the PF instead.Wei Gong reported that if virtio I/O is in progress when the driver isunbound or "0" is written to /sys/.../sriov_numvfs, the virtio I/Ooperation hangs, which may result in output like this: task:bash state:D stack: 0 pid: 1773 ppid: 1241 flags:0x00004002 Call Trace: schedule+0x4f/0xc0 blk_mq_freeze_queue_wait+0x69/0xa0 blk_mq_freeze_queue+0x1b/0x20 blk_cleanup_queue+0x3d/0xd0 virtblk_remove+0x3c/0xb0 [virtio_blk] virtio_dev_remove+0x4b/0x80 ... device_unregister+0x1b/0x60 unregister_virtio_device+0x18/0x30 virtio_pci_remove+0x41/0x80 pci_device_remove+0x3e/0xb0This happened because pci_device_is_present(VF) returned "false" invirtio_pci_remove(), so it called virtio_break_device().

Description: In the Linux kernel, the following vulnerability has been resolved:mmc: atmel-mci: fix return value check of mmc_add_host()mmc_add_host() may return error, if we ignore its return value,it will lead two issues:1. The memory that allocated in mmc_alloc_host() is leaked.2. In the remove() path, mmc_remove_host() will be called to delete device, but it's not added yet, it will lead a kernel crash because of null-ptr-deref in device_del().So fix this by checking the return value and calling mmc_free_host()in the error path.

CVE-2022-50661 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:seccomp: Move copy_seccomp() to no failure path.Our syzbot instance reported memory leaks in do_seccomp() [0], similarto the report [1]. It shows that we miss freeing struct seccomp_filterand some objects included in it.We can reproduce the issue with the program below [2] which calls oneseccomp() and two clone() syscalls.The first clone()d child exits earlier than its parent and sends asignal to kill it during the second clone(), more precisely before thefatal_signal_pending() test in copy_process(). When the parent receivesthe signal, it has to destroy the embryonic process and return -EINTR touser space. In the failure path, we have to call seccomp_filter_release()to decrement the filter's refcount.Initially, we called it in free_task() called from the failure path, butthe commit 3a15fb6ed92c ("seccomp: release filter after task is fullydead") moved it to release_task() to notify user space as early as possiblethat the filter is no longer used.To keep the change and current seccomp refcount semantics, let's movecopy_seccomp() just after the signal check and add a WARN_ON_ONCE() infree_task() for future debugging.[0]:unreferenced object 0xffff8880063add00 (size 256): comm "repro_seccomp", pid 230, jiffies 4294687090 (age 9.914s) hex dump (first 32 bytes): 01 00 00 00 01 00 00 00 00 00 00 00 00 00 00 00 ................ ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ backtrace: do_seccomp (./include/linux/slab.h:600 ./include/linux/slab.h:733 kernel/seccomp.c:666 kernel/seccomp.c:708 kernel/seccomp.c:1871 kernel/seccomp.c:1991) do_syscall_64 (arch/x86/entry/common.c:50 arch/x86/entry/common.c:80) entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:120)unreferenced object 0xffffc90000035000 (size 4096): comm "repro_seccomp", pid 230, jiffies 4294687090 (age 9.915s) hex dump (first 32 bytes): 01 00 00 00 00 00 00 00 00 00 00 00 05 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: __vmalloc_node_range (mm/vmalloc.c:3226) __vmalloc_node (mm/vmalloc.c:3261 (discriminator 4)) bpf_prog_alloc_no_stats (kernel/bpf/core.c:91) bpf_prog_alloc (kernel/bpf/core.c:129) bpf_prog_create_from_user (net/core/filter.c:1414) do_seccomp (kernel/seccomp.c:671 kernel/seccomp.c:708 kernel/seccomp.c:1871 kernel/seccomp.c:1991) do_syscall_64 (arch/x86/entry/common.c:50 arch/x86/entry/common.c:80) entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:120)unreferenced object 0xffff888003fa1000 (size 1024): comm "repro_seccomp", pid 230, jiffies 4294687090 (age 9.915s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: bpf_prog_alloc_no_stats (./include/linux/slab.h:600 ./include/linux/slab.h:733 kernel/bpf/core.c:95) bpf_prog_alloc (kernel/bpf/core.c:129) bpf_prog_create_from_user (net/core/filter.c:1414) do_seccomp (kernel/seccomp.c:671 kernel/seccomp.c:708 kernel/seccomp.c:1871 kernel/seccomp.c:1991) do_syscall_64 (arch/x86/entry/common.c:50 arch/x86/entry/common.c:80) entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:120)unreferenced object 0xffff888006360240 (size 16): comm "repro_seccomp", pid 230, jiffies 4294687090 (age 9.915s) hex dump (first 16 bytes): 01 00 37 00 76 65 72 6c e0 83 01 06 80 88 ff ff ..7.verl........ backtrace: bpf_prog_store_orig_filter (net/core/filter.c:1137) bpf_prog_create_from_user (net/core/filter.c:1428) do_seccomp (kernel/seccomp.c:671 kernel/seccomp.c:708 kernel/seccomp.c:1871 kernel/seccomp.c:1991) do_syscall_64 (arch/x86/entry/common.c:50 arch/x86/entry/common.c:80) entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:120)unreferenced object 0xffff888---truncated---

This happens because cache entry for thexattr block is marked as reusable (e_reusable set) although itsreference count is too big. When this inconsistency happens, thisinconsistent state is kept indefinitely and so ext4_xattr_block_set()keeps retrying indefinitely.The inconsistent state is caused by non-atomic update of e_reusable bit.e_reusable is part of a bitfield and e_reusable update can race withupdate of e_referenced bit in the same bitfield resulting in loss of oneof the updates. Fix the problem by using atomic bitops instead.This bug has been around for many years, but it became *much* easierto hit after commit 65f8b80053a1 ("ext4: fix race when reusing xattrblocks").

CVE-2022-50669 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:misc: ocxl: fix possible name leak in ocxl_file_register_afu()If device_register() returns error in ocxl_file_register_afu(),the name allocated by dev_set_name() need be freed. As commentof device_register() says, it should use put_device() to giveup the reference in the error path. So fix this by callingput_device(), then the name can be freed in kobject_cleanup(),and info is freed in info_release().

CVE-2022-50675 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:arm64: mte: Avoid setting PG_mte_tagged if no tags cleared or restoredPrior to commit 69e3b846d8a7 ("arm64: mte: Sync tags for pages where PTEis untagged"), mte_sync_tags() was only called for pte_tagged() entries(those mapped with PROT_MTE). Therefore mte_sync_tags() could safely usetest_and_set_bit(PG_mte_tagged, &page->flags) without inadvertentlysetting PG_mte_tagged on an untagged page.The above commit was required as guests may enable MTE without anycontrol at the stage 2 mapping, nor a PROT_MTE mapping in the VMM.However, the side-effect was that any page with a PTE that looked likeswap (or migration) was getting PG_mte_tagged set automatically. Asubsequent page copy (e.g. migration) copied the tags to the destinationpage even if the tags were owned by KASAN.This issue was masked by the page_kasan_tag_reset() call introduced incommit e5b8d9218951 ("arm64: mte: reset the page tag in page->flags").When this commit was reverted (20794545c146), KASAN started reportingaccess faults because the overriding tags in a page did not match theoriginal page->flags (with CONFIG_KASAN_HW_TAGS=y): BUG: KASAN: invalid-access in copy_page+0x10/0xd0 arch/arm64/lib/copy_page.S:26 Read at addr f5ff000017f2e000 by task syz-executor.1/2218 Pointer tag: [f5], memory tag: [f2]Move the PG_mte_tagged bit setting from mte_sync_tags() to the actualplace where tags are cleared (mte_sync_page_tags()) or restored(mte_restore_tags()).

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: silence the warning when evicting inode with dioread_nolockWhen evicting an inode with default dioread_nolock, it could be raced bythe unwritten extents converting kworker after writeback some newallocated dirty blocks. It convert unwritten extents to written, theextents could be merged to upper level and free extent blocks, so itcould mark the inode dirty again even this inode has been markedI_FREEING. But the inode->i_io_list check and warning inext4_evict_inode() missing this corner case. Fortunately,ext4_evict_inode() will wait all extents converting finished before thischeck, so it will not lead to inode use-after-free problem, every thingis OK besides this warning. The WARN_ON_ONCE was originally designedfor finding inode use-after-free issues in advance, but if we addcurrent dioread_nolock case in, it will become not quite useful, so fixthis warning by just remove this check. ====== WARNING: CPU: 7 PID: 1092 at fs/ext4/inode.c:227 ext4_evict_inode+0x875/0xc60 ...

CVE-2022-50731 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: akcipher - default implementation for setting a private keyChanges from v1: * removed the default implementation from set_pub_key: it is assumed that an implementation must always have this callback defined as there are no use case for an algorithm, which doesn't need a public keyMany akcipher implementations (like ECDSA) support only signatureverifications, so they don't have all callbacks defined.Commit 78a0324f4a53 ("crypto: akcipher - default implementations forrequest callbacks") introduced default callbacks for sign/verifyoperations, which just return an error code.However, these are not enough, because before calling sign the caller wouldlikely call set_priv_key first on the instantiated transform (as thein-kernel testmgr does). This function does not have a default stub, so thekernel crashes, when trying to set a private key on an akcipher, whichdoesn't support signature generation.I've noticed this, when trying to add a KAT vector for ECDSA signature tothe testmgr.With this patch the testmgr returns an error in dmesg (as it should)instead of crashing the kernel NULL ptr dereference.

Otherwise, when the userspace subsequently closes thedmabuf fd, we'd try to erroneously free the invalid sg table fromrelease_udmabuf resulting in the following crash reported by syzbot:general protection fault, probably for non-canonical address0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASANKASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]CPU: 0 PID: 3609 Comm: syz-executor487 Not tainted5.19.0-syzkaller-13930-g7ebfc85e2cd7 #0Hardware name: Google Google Compute Engine/Google Compute Engine, BIOSGoogle 07/22/2022RIP: 0010:dma_unmap_sgtable include/linux/dma-mapping.h:378 [inline]RIP: 0010:put_sg_table drivers/dma-buf/udmabuf.c:89 [inline]RIP: 0010:release_udmabuf+0xcb/0x4f0 drivers/dma-buf/udmabuf.c:114Code: 48 89 fa 48 c1 ea 03 80 3c 02 00 0f 85 2b 04 00 00 48 8d 7d 0c 4c8b 63 30 48 b8 00 00 00 00 00 fc ff df 48 89 fa 48 c1 ea 03 <0f> b6 1402 48 89 f8 83 e0 07 83 c0 03 38 d0 7c 08 84 d2 0f 85 e2RSP: 0018:ffffc900037efd30 EFLAGS: 00010246RAX: dffffc0000000000 RBX: ffffffff8cb67800 RCX: 0000000000000000RDX: 0000000000000000 RSI: ffffffff84ad27e0 RDI: 0000000000000000RBP: fffffffffffffff4 R08: 0000000000000005 R09: 0000000000000000R10: 0000000000000000 R11: 000000000008c07c R12: ffff88801fa05000R13: ffff888073db07e8 R14: ffff888025c25440 R15: 0000000000000000FS: 0000555555fc4300(0000) GS:ffff8880b9a00000(0000)knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007fc1c0ce06e4 CR3: 00000000715e6000 CR4: 00000000003506f0DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400Call Trace: dma_buf_release+0x157/0x2d0 drivers/dma-buf/dma-buf.c:78 __dentry_kill+0x42b/0x640 fs/dcache.c:612 dentry_kill fs/dcache.c:733 [inline] dput+0x806/0xdb0 fs/dcache.c:913 __fput+0x39c/0x9d0 fs/file_table.c:333 task_work_run+0xdd/0x1a0 kernel/task_work.c:177 ptrace_notify+0x114/0x140 kernel/signal.c:2353 ptrace_report_syscall include/linux/ptrace.h:420 [inline] ptrace_report_syscall_exit include/linux/ptrace.h:482 [inline] syscall_exit_work kernel/entry/common.c:249 [inline] syscall_exit_to_user_mode_prepare+0x129/0x280 kernel/entry/common.c:276 __syscall_exit_to_user_mode_work kernel/entry/common.c:281 [inline] syscall_exit_to_user_mode+0x9/0x50 kernel/entry/common.c:294 do_syscall_64+0x42/0xb0 arch/x86/entry/common.c:86 entry_SYSCALL_64_after_hwframe+0x63/0xcdRIP: 0033:0x7fc1c0c35b6bCode: 0f 05 48 3d 00 f0 ff ff 77 45 c3 0f 1f 40 00 48 83 ec 18 89 7c 240c e8 63 fc ff ff 8b 7c 24 0c 41 89 c0 b8 03 00 00 00 0f 05 <48> 3d 00f0 ff ff 77 35 44 89 c7 89 44 24 0c e8 a1 fc ff ff 8b 44RSP: 002b:00007ffd78a06090 EFLAGS: 00000293 ORIG_RAX: 0000000000000003RAX: 0000000000000000 RBX: 0000000000000007 RCX: 00007fc1c0c35b6bRDX: 0000000020000280 RSI: 0000000040086200 RDI: 0000000000000006RBP: 0000000000000007 R08: 0000000000000000 R09: 0000000000000000R10: 0000000000000000 R11: 0000000000000293 R12: 000000000000000cR13: 0000000000000003 R14: 00007fc1c0cfe4a0 R15: 00007ffd78a06140 Modules linked in:---[ end trace 0000000000000000 ]---RIP: 0010:dma_unmap_sgtable include/linux/dma-mapping.h:378 [inline]RIP: 0010:put_sg_table drivers/dma-buf/udmabuf.c:89 [inline]RIP: 0010:release_udmabuf+0xcb/0x4f0 drivers/dma-buf/udmabuf.c:114

Description: In the Linux kernel, the following vulnerability has been resolved:ipu3-imgu: Fix NULL pointer dereference in imgu_subdev_set_selection()Calling v4l2_subdev_get_try_crop() and v4l2_subdev_get_try_compose()with a subdev state of NULL leads to a NULL pointer dereference. Thiscan currently happen in imgu_subdev_set_selection() when the statepassed in is NULL, as this method first gets pointers to both the "try"and "active" states and only then decides which to use.The same issue has been addressed for imgu_subdev_get_selection() withcommit 30d03a0de650 ("ipu3-imgu: Fix NULL pointer dereference in activeselection access"). However the issue still persists inimgu_subdev_set_selection().Therefore, apply a similar fix as done in the aforementioned commit toimgu_subdev_set_selection(). To keep things a bit cleaner, introducehelper functions for "crop" and "compose" access and use them in bothimgu_subdev_set_selection() and imgu_subdev_get_selection().

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: lpfc: Fix memory leak in lpfc_create_port()Commit 5e633302ace1 ("scsi: lpfc: vmid: Add support for VMID in mailboxcommand") introduced allocations for the VMID resources inlpfc_create_port() after the call to scsi_host_alloc(). Upon failure on theVMID allocations, the new code would branch to the 'out' label, whichreturns NULL without unwinding anything, thus skipping the call toscsi_host_put().Fix the problem by creating a separate label 'out_free_vmid' to unwind theVMID resources and make the 'out_put_shost' label call onlyscsi_host_put(), as was done before the introduction of allocations forVMID.

CVE-2022-50838 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: stream: purge sk_error_queue in sk_stream_kill_queues()Changheon Lee reported TCP socket leaks, with a nice repro.It seems we leak TCP sockets with the following sequence:1) SOF_TIMESTAMPING_TX_ACK is enabled on the socket. Each ACK will cook an skb put in error queue, from __skb_tstamp_tx(). __skb_tstamp_tx() is using skb_clone(), unless SOF_TIMESTAMPING_OPT_TSONLY was also requested.2) If the application is also using MSG_ZEROCOPY, then we put in the error queue cloned skbs that had a struct ubuf_info attached to them. Whenever an struct ubuf_info is allocated, sock_zerocopy_alloc() does a sock_hold(). As long as the cloned skbs are still in sk_error_queue, socket refcount is kept elevated.3) Application closes the socket, while error queue is not empty.Since tcp_close() no longer purges the socket error queue,we might end up with a TCP socket with at least one skb inerror queue keeping the socket alive forever.This bug can be (ab)used to consume all kernel memoryand freeze the host.We need to purge the error queue, with proper synchronizationagainst concurrent writers.

Ultimately, smu_od_edit_dpm_table() calls->od_edit_dpm_table() from 'struct pptable_funcs' andpp_odn_edit_dpm_table() calls ->odn_edit_dpm_table() from 'structpp_hwmgr_func', which both have a second parameter type of 'enumPP_OD_DPM_TABLE_COMMAND'.Update the type parameter in both the prototype in 'struct amd_pm_funcs'and pp_odn_edit_dpm_table() to 'enum PP_OD_DPM_TABLE_COMMAND', whichcleans up the warning.

Pstore's ram backend reuses those reserved pages to change thememory type (writeback or non-cached) by passing the pages to vmap()(see pfn_to_page() usage in persistent_ram_vmap() for more details) withspecific flags. When read_kcore() starts iterating over the vmallocregion, it runs over the virtual address that vmap() returned forramoops. In aligned_vread() the virtual address is passed tovmalloc_to_page() which returns the page struct for the reserved lowmemarea. That lowmem page is passed to kmap_atomic(), which effectivelycalls page_to_virt() that assumes a lowmem page struct must be directlyaccessible with __va() and friends. These pages are mapped via vmap()though, and the lowmem mapping was never made, so accessing them via thelowmem virtual address oopses like above.Let's side-step this problem by passing VM_IOREMAP to vmap(). This willtell vread() to not include the ramoops region in the kcore. Instead thearea will look like a bunch of zeros. The alternative is to teach kmap()about vmalloc areas that intersect with lowmem. Presumably such a changeisn't a one-liner, and there isn't much interest in inspecting theramoops region in kcore files anyway, so the most expedient route istaken for now.

CVE-2022-50865 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:tcp: fix a signed-integer-overflow bug in tcp_add_backlog()The type of sk_rcvbuf and sk_sndbuf in struct sock is int, andin tcp_add_backlog(), the variable limit is caculated by addingsk_rcvbuf, sk_sndbuf and 64 * 1024, it may exceed the max valueof int and overflow. This patch reduces the limit budget byhalving the sndbuf to solve this issue since ACK packets are muchsmaller than the payload.

CVE-2022-50870 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:powerpc/rtas: avoid device tree lookups in rtas_os_term()rtas_os_term() is called during panic. Its behavior depends on a coupleof conditions in the /rtas node of the device tree, the traversal ofwhich entails locking and local IRQ state changes. If the kernel panicswhile devtree_lock is held, rtas_os_term() as currently written couldhang.Instead of discovering the relevant characteristics at panic time,cache them in file-static variables at boot. Note the lookup for"ibm,extended-os-term" is converted to of_property_read_bool() since itis a boolean property, not an RTAS function token.[mpe: Incorporate suggested change from Nick]

CVE-2023-52486 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:drm: Don't unref the same fb many times by mistake due to deadlock handlingIf we get a deadlock after the fb lookup in drm_mode_page_flip_ioctl()we proceed to unref the fb and then retry the whole thing from the top.But we forget to reset the fb pointer back to NULL, and so if we thenget another error during the retry, before the fb lookup, we proceedthe unref the same fb again without having gotten another reference.The end result is that the fb will (eventually) end up being freedwhile it's still in use.Reset fb to NULL once we've unreffed it to avoid doing it againuntil we've done another fb lookup.This turned out to be pretty easy to hit on a DG2 when doing asyncflips (and CONFIG_DEBUG_WW_MUTEX_SLOWPATH=y). The first symptom Isaw that drm_closefb() simply got stuck in a busy loop while walkingthe framebuffer list. Fortunately I was able to convince it to oopsinstead, and from there it was easier to track down the culprit.

CVE-2023-52488 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:serial: sc16is7xx: convert from _raw_ to _noinc_ regmap functions for FIFOThe SC16IS7XX IC supports a burst mode to access the FIFOs where theinitial register address is sent ($00), followed by all the FIFO datawithout having to resend the register address each time. In this mode, theIC doesn't increment the register address for each R/W byte.The regmap_raw_read() and regmap_raw_write() are functions which canperform IO over multiple registers. They are currently used to read/writefrom/to the FIFO, and although they operate correctly in this burst mode onthe SPI bus, they would corrupt the regmap cache if it was not disabledmanually. The reason is that when the R/W size is more than 1 byte, thesefunctions assume that the register address is incremented and handle thecache accordingly.Convert FIFO R/W functions to use the regmap _noinc_ versions in order toremove the manual cache control which was a workaround when using the_raw_ versions. FIFO registers are properly declared as volatile socache will not be used/updated for FIFO accesses.

CVE-2023-52498 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:PM: sleep: Fix possible deadlocks in core system-wide PM codeIt is reported that in low-memory situations the system-wide resume corecode deadlocks, because async_schedule_dev() executes its argumentfunction synchronously if it cannot allocate memory (and not only inthat case) and that function attempts to acquire a mutex that is alreadyheld. Executing the argument function synchronously from withindpm_async_fn() may also be problematic for ordering reasons (it maycause a consumer device's resume callback to be invoked before arequisite supplier device's one, for example).Address this by changing the code in question to useasync_schedule_dev_nocall() for scheduling the asynchronousexecution of device suspend and resume functions and to directlyrun them synchronously if async_schedule_dev_nocall() returns false.

CVE-2023-52527 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ipv4, ipv6: Fix handling of transhdrlen in __ip{,6}_append_data()Including the transhdrlen in length is a problem when the packet ispartially filled (e.g. something like send(MSG_MORE) happened previously)when appending to an IPv4 or IPv6 packet as we don't want to repeat thetransport header or account for it twice. This can happen under somecircumstances, such as splicing into an L2TP socket.The symptom observed is a warning in __ip6_append_data(): WARNING: CPU: 1 PID: 5042 at net/ipv6/ip6_output.c:1800 __ip6_append_data.isra.0+0x1be8/0x47f0 net/ipv6/ip6_output.c:1800that occurs when MSG_SPLICE_PAGES is used to append more data to an alreadypartially occupied skbuff. The warning occurs when 'copy' is larger thanthe amount of data in the message iterator. This is because the requestedlength includes the transport header length when it shouldn't. This can betriggered by, for example: sfd = socket(AF_INET6, SOCK_DGRAM, IPPROTO_L2TP); bind(sfd, ...); // ::1 connect(sfd, ...); // ::1 port 7 send(sfd, buffer, 4100, MSG_MORE); sendfile(sfd, dfd, NULL, 1024);Fix this by only adding transhdrlen into the length if the write queue isempty in l2tp_ip6_sendmsg(), analogously to how UDP does things.l2tp_ip_sendmsg() looks like it won't suffer from this problem as it buildsthe UDP packet itself.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nf_tables: fix memleak when more than 255 elements expiredWhen more than 255 elements expired we're supposed to switch to a new gccontainer structure.This never happens: u8 type will wrap before reaching the boundaryand nft_trans_gc_space() always returns true.This means we recycle the initial gc container structure andlose track of the elements that came before.While at it, don't deref 'gc' after we've passed it to call_rcu.

CVE-2023-52598 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:s390/ptrace: handle setting of fpc register correctlyIf the content of the floating point control (fpc) register of a tracedprocess is modified with the ptrace interface the new value is tested forvalidity by temporarily loading it into the fpc register.This may lead to corruption of the fpc register of the tracing process:if an interrupt happens while the value is temporarily loaded into thefpc register, and within interrupt context floating point or vectorregisters are used, the current fp/vx registers are saved withsave_fpu_regs() assuming they belong to user space and will be loaded intofp/vx registers when returning to user space.test_fp_ctl() restores the original user space fpc register value, howeverit will be discarded, when returning to user space.In result the tracer will incorrectly continue to run with the value thatwas supposed to be used for the traced process.Fix this by saving fpu register contents with save_fpu_regs() before usingtest_fp_ctl().

CVE-2023-52606 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:powerpc/lib: Validate size for vector operationsSome of the fp/vmx code in sstep.c assume a certain maximum size for theinstructions being emulated. The size of those operations however isdetermined separately in analyse_instr().Add a check to validate the assumption on the maximum size of theoperations, so as to prevent any unintended kernel stack corruption.

CVE-2023-52608 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:firmware: arm_scmi: Check mailbox/SMT channel for consistencyOn reception of a completion interrupt the shared memory area is accessedto retrieve the message header at first and then, if the message sequencenumber identifies a transaction which is still pending, the relatedpayload is fetched too.When an SCMI command times out the channel ownership remains with theplatform until eventually a late reply is received and, as a consequence,any further transmission attempt remains pending, waiting for the channelto be relinquished by the platform.Once that late reply is received the channel ownership is given backto the agent and any pending request is then allowed to proceed andoverwrite the SMT area of the just delivered late reply; then the waitfor the reply to the new request starts.It has been observed that the spurious IRQ related to the late reply canbe wrongly associated with the freshly enqueued request: when that happensthe SCMI stack in-flight lookup procedure is fooled by the fact that themessage header now present in the SMT area is related to the new pendingtransaction, even though the real reply has still to arrive.This race-condition on the A2P channel can be detected by looking at thechannel status bits: a genuine reply from the platform will have set thechannel free bit before triggering the completion IRQ.Add a consistency check to validate such condition in the A2P ISR.

Description: In the Linux kernel, the following vulnerability has been resolved:iio: adc: ad7091r: Allow users to configure device eventsAD7091R-5 devices are supported by the ad7091r-5 driver together withthe ad7091r-base driver. Those drivers declared iio events for notifyinguser space when ADC readings fall bellow the thresholds of low limitregisters or above the values set in high limit registers.However, to configure iio events and their thresholds, a set of callbackfunctions must be implemented and those were not present until now.The consequence of trying to configure ad7091r-5 events without theproper callback functions was a null pointer dereference in the kernelbecause the pointers to the callback functions were not set.Implement event configuration callbacks allowing users to read/writeevent thresholds and enable/disable event generation.Since the event spec structs are generic to AD7091R devices, also movethose from the ad7091r-5 driver the base driver so they can be reusedwhen support for ad7091r-2/-4/-8 be added.

Description: In the Linux kernel, the following vulnerability has been resolved:can: j1939: prevent deadlock by changing j1939_socks_lock to rwlockThe following 3 locks would race against each other, causing thedeadlock situation in the Syzbot bug report:- j1939_socks_lock- active_session_list_lock- sk_session_queue_lockA reasonable fix is to change j1939_socks_lock to an rwlock, since inthe rare situations where a write lock is required for the linked listthat j1939_socks_lock is protecting, the code does not attempt toacquire any more locks. This would break the circular lock dependency,where, for example, the current thread already locks j1939_socks_lockand attempts to acquire sk_session_queue_lock, and at the same time,another thread attempts to acquire j1939_socks_lock while holdingsk_session_queue_lock.NOTE: This patch along does not fix the unregister_netdevice bugreported by Syzbot; instead, it solves a deadlock situation to preparefor one or more further patches to actually fix the Syzbot bug, whichappears to be a reference counting problem within the j1939 codebase.[mkl: remove unrelated newline change]

In normalcase, aead_request_complete() will be called in pcrypt_aead_serial and thereturn err is 0 for padata_do_parallel. But, when pinst->flags isPADATA_RESET, the return err is -EBUSY for padata_do_parallel, and itwon't call aead_request_complete(). Therefore, test_aead_vec_cfg willhung at wait_for_completion(&wait->completion), which will causehungtask.The problem comes as following:(padata_do_parallel) | rcu_read_lock_bh(); | err = -EINVAL; | (padata_replace) | pinst->flags |= PADATA_RESET; err = -EBUSY | if (pinst->flags & PADATA_RESET) | rcu_read_unlock_bh() | return errIn order to resolve the problem, we replace the return err -EBUSY with-EAGAIN, which means parallel_data is changing, and the caller should callit again.v3:remove retry and just change the return err.v2:introduce padata_try_do_parallel() in pcrypt_aead_encrypt andpcrypt_aead_decrypt to solve the hungtask.

All these areprotected by a test skb->protocol == ETH_P_802_2. Which does notprotect against this tun scenario.But the mac_len test added in this patch in llc_fixup_skb willindirectly protect those too. That is called from llc_rcv before anyother LLC code.It is tempting to just add a blanket mac_len check in llc_rcv, butnot sure whether that could break valid LLC paths that do not assumean Ethernet header. 802.2 LLC may be used on top of non-802.3protocols in principle. The below referenced commit shows that usedto, on top of Token Ring.At least one of the three eth_hdr uses goes back to before the startof git history. But the one that syzbot exercises is introduced inthis commit. That commit is old enough (2008), that effectively allstable kernels should receive this.

If a link name which is not null-terminated is passed throughnetlink, strstr() and similar functions can cause buffer overrun. Thiscauses the above issue.This patch changes the nla_policy for bearer-related names from NLA_STRINGto NLA_NUL_STRING. This resolves the issue by ensuring that onlynull-terminated strings are accepted as bearer-related names.syzbot reported similar uninit-value issue related to bearer names [2]. Theroot cause of this issue is that a non-null-terminated bearer name waspassed. This patch also resolved this issue.

CVE-2023-52906 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: act_mpls: Fix warning during failed attribute validationThe 'TCA_MPLS_LABEL' attribute is of 'NLA_U32' type, but has avalidation type of 'NLA_VALIDATE_FUNCTION'. This is an invalidcombination according to the comment above 'struct nla_policy':"Meaning of `validate' field, use via NLA_POLICY_VALIDATE_FN: NLA_BINARY Validation function called for the attribute. All other Unused - but note that it's a union"This can trigger the warning [1] in nla_get_range_unsigned() whenvalidation of the attribute fails. Despite being of 'NLA_U32' type, theassociated 'min'/'max' fields in the policy are negative as they arealiased by the 'validate' field.Fix by changing the attribute type to 'NLA_BINARY' which is consistentwith the above comment and all other users of NLA_POLICY_VALIDATE_FN().As a result, move the length validation to the validation function.No regressions in MPLS tests: # ./tdc.py -f tc-tests/actions/mpls.json [...] # echo $? 0[1]WARNING: CPU: 0 PID: 17743 at lib/nlattr.c:118nla_get_range_unsigned+0x1d8/0x1e0 lib/nlattr.c:117Modules linked in:CPU: 0 PID: 17743 Comm: syz-executor.0 Not tainted 6.1.0-rc8 #3Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOSrel-1.13.0-48-gd9c812dda519-prebuilt.qemu.org 04/01/2014RIP: 0010:nla_get_range_unsigned+0x1d8/0x1e0 lib/nlattr.c:117[...]Call Trace: __netlink_policy_dump_write_attr+0x23d/0x990 net/netlink/policy.c:310 netlink_policy_dump_write_attr+0x22/0x30 net/netlink/policy.c:411 netlink_ack_tlv_fill net/netlink/af_netlink.c:2454 [inline] netlink_ack+0x546/0x760 net/netlink/af_netlink.c:2506 netlink_rcv_skb+0x1b7/0x240 net/netlink/af_netlink.c:2546 rtnetlink_rcv+0x18/0x20 net/core/rtnetlink.c:6109 netlink_unicast_kernel net/netlink/af_netlink.c:1319 [inline] netlink_unicast+0x5e9/0x6b0 net/netlink/af_netlink.c:1345 netlink_sendmsg+0x739/0x860 net/netlink/af_netlink.c:1921 sock_sendmsg_nosec net/socket.c:714 [inline] sock_sendmsg net/socket.c:734 [inline] ____sys_sendmsg+0x38f/0x500 net/socket.c:2482 ___sys_sendmsg net/socket.c:2536 [inline] __sys_sendmsg+0x197/0x230 net/socket.c:2565 __do_sys_sendmsg net/socket.c:2574 [inline] __se_sys_sendmsg net/socket.c:2572 [inline] __x64_sys_sendmsg+0x42/0x50 net/socket.c:2572 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x2b/0x70 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcd

CVE-2023-52920 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: support non-r10 register spill/fill to/from stack in precision trackingUse instruction (jump) history to record instructions that performedregister spill/fill to/from stack, regardless if this was done throughread-only r10 register, or any other register after copying r10 into it*and* potentially adjusting offset.To make this work reliably, we push extra per-instruction flags intoinstruction history, encoding stack slot index (spi) and stack framenumber in extra 10 bit flags we take away from prev_idx in instructionhistory. We don't touch idx field for maximum performance, as it'schecked most frequently during backtracking.This change removes basically the last remaining practical limitation ofprecision backtracking logic in BPF verifier. It fixes knowndeficiencies, but also opens up new opportunities to reduce number ofverified states, explored in the subsequent patches.There are only three differences in selftests' BPF object filesaccording to veristat, all in the positive direction (less states).File Program Insns (A) Insns (B) Insns (DIFF) States (A) States (B) States (DIFF)-------------------------------------- ------------- --------- --------- ------------- ---------- ---------- -------------test_cls_redirect_dynptr.bpf.linked3.o cls_redirect 2987 2864 -123 (-4.12%) 240 231 -9 (-3.75%)xdp_synproxy_kern.bpf.linked3.o syncookie_tc 82848 82661 -187 (-0.23%) 5107 5073 -34 (-0.67%)xdp_synproxy_kern.bpf.linked3.o syncookie_xdp 85116 84964 -152 (-0.18%) 5162 5130 -32 (-0.62%)Note, I avoided renaming jmp_history to more generic insn_hist tominimize number of lines changed and potential merge conflicts betweenbpf and bpf-next trees.Notice also cur_hist_entry pointer reset to NULL at the beginning ofinstruction verification loop. This pointer avoids the problem ofrelying on last jump history entry's insn_idx to determine whether wealready have entry for current instruction or not. It can happen that weadded jump history entry because current instruction is_jmp_point(), butalso we need to add instruction flags for stack access. In this case, wedon't want to entries, so we need to reuse last added entry, if it ispresent.Relying on insn_idx comparison has the same ambiguity problem as the onethat was fixed recently in [0], so we avoid that.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/i915: Fix request ref counting during error capture & debugfs dumpWhen GuC support was added to error capture, the reference countingaround the request object was broken. Fix it up.The context based search manages the spinlocking around the searchinternally. So it needs to grab the reference count internally aswell. The execlist only request based search relies on externallocking, so it needs an external reference count but within thespinlock not outside it.The only other caller of the context based search is the code fordumping engine state to debugfs. That code wasn't previously gettingan explicit reference at all as it does everything while holding theexeclist specific spinlock. So, that needs updaing as well as thatspinlock doesn't help when using GuC submission. Rather than trying toconditionally get/put depending on submission model, just change it toalways do the get/put.v2: Explicitly document adding an extra blank line in some dense code(Andy Shevchenko). Fix multiple potential null pointer derefs in caseof no request found (some spotted by Tvrtko, but there was more!).Also fix a leaked request in case of !started and another in__guc_reset_context now that intel_context_find_active_request isactually reference counting the returned request.v3: Add a _get suffix to intel_context_find_active_request now that itgrabs a reference (Daniele).v4: Split the intel_guc_find_hung_context change to a separate patchand rename intel_context_find_active_request_get tointel_context_get_active_request (Tvrtko).v5: s/locking/reference counting/ in commit message (Tvrtko)(cherry picked from commit 3700e353781e27f1bc7222f51f2cc36cbeb9b4ec)

CVE-2023-52986 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf, sockmap: Check for any of tcp_bpf_prots when cloning a listenerA listening socket linked to a sockmap has its sk_prot overridden. Itpoints to one of the struct proto variants in tcp_bpf_prots. The variantdepends on the socket's family and which sockmap programs are attached.A child socket cloned from a TCP listener initially inherits their sk_prot.But before cloning is finished, we restore the child's proto to thelistener's original non-tcp_bpf_prots one. This happens intcp_create_openreq_child -> tcp_bpf_clone.Today, in tcp_bpf_clone we detect if the child's proto should be restoredby checking only for the TCP_BPF_BASE proto variant. This is notcorrect. The sk_prot of listening socket linked to a sockmap can point toto any variant in tcp_bpf_prots.If the listeners sk_prot happens to be not the TCP_BPF_BASE variant, thenthe child socket unintentionally is left if the inherited sk_prot bytcp_bpf_clone.This leads to issues like infinite recursion on close [1], because thechild state is otherwise not set up for use with tcp_bpf_prot operations.Adjust the check in tcp_bpf_clone to detect all of tcp_bpf_prots variants.Note that it wouldn't be sufficient to check the socket state whenoverriding the sk_prot in tcp_bpf_update_proto in order to always use theTCP_BPF_BASE variant for listening sockets. Since commitb8b8315e39ff ("bpf, sockmap: Remove unhash handler for BPF sockmap usage")it is possible for a socket to transition to TCP_LISTEN state while alreadylinked to a sockmap, e.g. connect() -> insert into map ->connect(AF_UNSPEC) -> listen().[1]: https://lore.kernel.org/all/00000000000073b14905ef2e7401@google.com/

CVE-2023-53021 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: sch_taprio: fix possible use-after-freesyzbot reported a nasty crash [1] in net_tx_action() whichmade little sense until we got a repro.This repro installs a taprio qdisc, but providing aninvalid TCA_RATE attribute.qdisc_create() has to destroy the just initializedtaprio qdisc, and taprio_destroy() is called.However, the hrtimer used by taprio had already fired,therefore advance_sched() called __netif_schedule().Then net_tx_action was trying to use a destroyed qdisc.We can not undo the __netif_schedule(), so we must waituntil one cpu serviced the qdisc before we can proceed.Many thanks to Alexander Potapenko for his help.[1]BUG: KMSAN: uninit-value in queued_spin_trylock include/asm-generic/qspinlock.h:94 [inline]BUG: KMSAN: uninit-value in do_raw_spin_trylock include/linux/spinlock.h:191 [inline]BUG: KMSAN: uninit-value in __raw_spin_trylock include/linux/spinlock_api_smp.h:89 [inline]BUG: KMSAN: uninit-value in _raw_spin_trylock+0x92/0xa0 kernel/locking/spinlock.c:138 queued_spin_trylock include/asm-generic/qspinlock.h:94 [inline] do_raw_spin_trylock include/linux/spinlock.h:191 [inline] __raw_spin_trylock include/linux/spinlock_api_smp.h:89 [inline] _raw_spin_trylock+0x92/0xa0 kernel/locking/spinlock.c:138 spin_trylock include/linux/spinlock.h:359 [inline] qdisc_run_begin include/net/sch_generic.h:187 [inline] qdisc_run+0xee/0x540 include/net/pkt_sched.h:125 net_tx_action+0x77c/0x9a0 net/core/dev.c:5086 __do_softirq+0x1cc/0x7fb kernel/softirq.c:571 run_ksoftirqd+0x2c/0x50 kernel/softirq.c:934 smpboot_thread_fn+0x554/0x9f0 kernel/smpboot.c:164 kthread+0x31b/0x430 kernel/kthread.c:376 ret_from_fork+0x1f/0x30Uninit was created at: slab_post_alloc_hook mm/slab.h:732 [inline] slab_alloc_node mm/slub.c:3258 [inline] __kmalloc_node_track_caller+0x814/0x1250 mm/slub.c:4970 kmalloc_reserve net/core/skbuff.c:358 [inline] __alloc_skb+0x346/0xcf0 net/core/skbuff.c:430 alloc_skb include/linux/skbuff.h:1257 [inline] nlmsg_new include/net/netlink.h:953 [inline] netlink_ack+0x5f3/0x12b0 net/netlink/af_netlink.c:2436 netlink_rcv_skb+0x55d/0x6c0 net/netlink/af_netlink.c:2507 rtnetlink_rcv+0x30/0x40 net/core/rtnetlink.c:6108 netlink_unicast_kernel net/netlink/af_netlink.c:1319 [inline] netlink_unicast+0xf3b/0x1270 net/netlink/af_netlink.c:1345 netlink_sendmsg+0x1288/0x1440 net/netlink/af_netlink.c:1921 sock_sendmsg_nosec net/socket.c:714 [inline] sock_sendmsg net/socket.c:734 [inline] ____sys_sendmsg+0xabc/0xe90 net/socket.c:2482 ___sys_sendmsg+0x2a1/0x3f0 net/socket.c:2536 __sys_sendmsg net/socket.c:2565 [inline] __do_sys_sendmsg net/socket.c:2574 [inline] __se_sys_sendmsg net/socket.c:2572 [inline] __x64_sys_sendmsg+0x367/0x540 net/socket.c:2572 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x3d/0xb0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcdCPU: 0 PID: 13 Comm: ksoftirqd/0 Not tainted 6.0.0-rc2-syzkaller-47461-gac3859c02d7f #0Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 07/22/2022

If we hold the netif_tx_lock() when there isan interrupt, and the NET_TX softirq then gets scheduled, this will takethe netif_tx_lock() a second time and deadlock the kernel.To solve this, use netif_tx_lock_bh(), which blocks softirqs fromrunning.

Description: In the Linux kernel, the following vulnerability has been resolved:bonding: restore bond's IFF_SLAVE flag if a non-eth dev enslave failssyzbot reported a warning[1] where the bond device itself is a slave andwe try to enslave a non-ethernet device as the first slave which failsbut then in the error path when ether_setup() restores the bond deviceit also clears all flags. In my previous fix[2] I restored theIFF_MASTER flag, but I didn't consider the case that the bond deviceitself might also be a slave with IFF_SLAVE set, so we need to restorethat flag as well. Use the bond_ether_setup helper which does the rightthing and restores the bond's flags properly.Steps to reproduce using a nlmon dev: $ ip l add nlmon0 type nlmon $ ip l add bond1 type bond $ ip l add bond2 type bond $ ip l set bond1 master bond2 $ ip l set dev nlmon0 master bond1 $ ip -d l sh dev bond1 22: bond1: mtu 1500 qdisc noqueue master bond2 state DOWN mode DEFAULT group default qlen 1000 (now bond1's IFF_SLAVE flag is gone and we'll hit a warning[3] if we try to delete it)[1] https://syzkaller.appspot.com/bug?id=391c7b1f6522182899efba27d891f1743e8eb3ef[2] commit 7d5cd2ce5292 ("bonding: correctly handle bonding type change on enslave failure")[3] example warning: [ 27.008664] bond1: (slave nlmon0): The slave device specified does not support setting the MAC address [ 27.008692] bond1: (slave nlmon0): Error -95 calling set_mac_address [ 32.464639] bond1 (unregistering): Released all slaves [ 32.464685] ------------[ cut here ]------------ [ 32.464686] WARNING: CPU: 1 PID: 2004 at net/core/dev.c:10829 unregister_netdevice_many+0x72a/0x780 [ 32.464694] Modules linked in: br_netfilter bridge bonding virtio_net [ 32.464699] CPU: 1 PID: 2004 Comm: ip Kdump: loaded Not tainted 5.18.0-rc3+ #47 [ 32.464703] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.1-2.fc37 04/01/2014 [ 32.464704] RIP: 0010:unregister_netdevice_many+0x72a/0x780 [ 32.464707] Code: 99 fd ff ff ba 90 1a 00 00 48 c7 c6 f4 02 66 96 48 c7 c7 20 4d 35 96 c6 05 fa c7 2b 02 01 e8 be 6f 4a 00 0f 0b e9 73 fd ff ff <0f> 0b e9 5f fd ff ff 80 3d e3 c7 2b 02 00 0f 85 3b fd ff ff ba 59 [ 32.464710] RSP: 0018:ffffa006422d7820 EFLAGS: 00010206 [ 32.464712] RAX: ffff8f6e077140a0 RBX: ffffa006422d7888 RCX: 0000000000000000 [ 32.464714] RDX: ffff8f6e12edbe58 RSI: 0000000000000296 RDI: ffffffff96d4a520 [ 32.464716] RBP: ffff8f6e07714000 R08: ffffffff96d63600 R09: ffffa006422d7728 [ 32.464717] R10: 0000000000000ec0 R11: ffffffff9698c988 R12: ffff8f6e12edb140 [ 32.464719] R13: dead000000000122 R14: dead000000000100 R15: ffff8f6e12edb140 [ 32.464723] FS: 00007f297c2f1740(0000) GS:ffff8f6e5d900000(0000) knlGS:0000000000000000 [ 32.464725] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 32.464726] CR2: 00007f297bf1c800 CR3: 00000000115e8000 CR4: 0000000000350ee0 [ 32.464730] Call Trace: [ 32.464763] [ 32.464767] rtnl_dellink+0x13e/0x380 [ 32.464776] ? cred_has_capability.isra.0+0x68/0x100 [ 32.464780] ? __rtnl_unlock+0x33/0x60 [ 32.464783] ? bpf_lsm_capset+0x10/0x10 [ 32.464786] ? security_capable+0x36/0x50 [ 32.464790] rtnetlink_rcv_msg+0x14e/0x3b0 [ 32.464792] ? _copy_to_iter+0xb1/0x790 [ 32.464796] ? post_alloc_hook+0xa0/0x160 [ 32.464799] ? rtnl_calcit.isra.0+0x110/0x110 [ 32.464802] netlink_rcv_skb+0x50/0xf0 [ 32.464806] netlink_unicast+0x216/0x340 [ 32.464809] netlink_sendmsg+0x23f/0x480 [ 32.464812] sock_sendmsg+0x5e/0x60 [ 32.464815] ____sys_sendmsg+0x22c/0x270 [ 32.464818] ? import_iovec+0x17/0x20 [ 32.464821] ? sendmsg_copy_msghdr+0x59/0x90 [ 32.464823] ? do_set_pte+0xa0/0xe0 [ 32.464828] ___sys_sendmsg+0x81/0xc0 [ 32.464832] ? mod_objcg_state+0xc6/0x300 [ 32.464835] ? refill_obj_stock+0xa9/0x160 [ 32.464838] ? memcg_slab_free_hook+0x1a5/0x1f0 [ 32.464842] __sys_sendm---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:media: dw2102: Fix null-ptr-deref in dw2102_i2c_transfer()In dw2102_i2c_transfer, msg is controlled by user. When msg[i].bufis null and msg[i].len is zero, former checks on msg[i].buf would bepassed. Malicious data finally reach dw2102_i2c_transfer. If accessingmsg[i].buf[0] without sanity check, null ptr deref would happen.We add check on msg[i].len to prevent crash.Similar commit:commit 950e252cb469("[media] dw2102: limit messages to buffer size")

CVE-2023-53178 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm: fix zswap writeback race conditionThe zswap writeback mechanism can cause a race condition resulting inmemory corruption, where a swapped out page gets swapped in with data thatwas written to a different page.The race unfolds like this:1. a page with data A and swap offset X is stored in zswap2. page A is removed off the LRU by zpool driver for writeback in zswap-shrink work, data for A is mapped by zpool driver3. user space program faults and invalidates page entry A, offset X is considered free4. kswapd stores page B at offset X in zswap (zswap could also be full, if so, page B would then be IOed to X, then skip step 5.)5. entry A is replaced by B in tree->rbroot, this doesn't affect the local reference held by zswap-shrink work6. zswap-shrink work writes back A at X, and frees zswap entry A7. swapin of slot X brings A in memory instead of BThe fix:Once the swap page cache has been allocated (case ZSWAP_SWAPCACHE_NEW),zswap-shrink work just checks that the local zswap_entry reference isstill the same as the one in the tree. If it's not the same it means thatit's either been invalidated or replaced, in both cases the writeback isaborted because the local entry contains stale data.Reproducer:I originally found this by running `stress` overnight to validate my workon the zswap writeback mechanism, it manifested after hours on my testmachine. The key to make it happen is having zswap writebacks, sowhatever setup pumps /sys/kernel/debug/zswap/written_back_pages should dothe trick.In order to reproduce this faster on a vm, I setup a system with ~100M ofavailable memory and a 500M swap file, then running `stress --vm 1--vm-bytes 300000000 --vm-stride 4000` makes it happen in matter of tensof minutes. One can speed things up even more by swinging/sys/module/zswap/parameters/max_pool_percent up and down between, say, 20and 1; this makes it reproduce in tens of seconds. It's crucial to set`--vm-stride` to something other than 4096 otherwise `stress` won'trealize that memory has been corrupted because all pages would have thesame data.

CVE-2023-53186 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:skbuff: Fix a race between coalescing and releasing SKBsCommit 1effe8ca4e34 ("skbuff: fix coalescing for page_pool fragmentrecycling") allowed coalescing to proceed with non page pool page and pagepool page when @from is cloned, i.e.to->pp_recycle --> falsefrom->pp_recycle --> trueskb_cloned(from) --> trueHowever, it actually requires skb_cloned(@from) to hold true untilcoalescing finishes in this situation. If the other cloned SKB isreleased while the merging is in process, from_shinfo->nr_frags will beset to 0 toward the end of the function, causing the increment of fragpage _refcount to be unexpectedly skipped resulting in inconsistentreference counts. Later when SKB(@to) is released, it frees the pagedirectly even though the page pool page is still in use, leading touse-after-free or double-free errors. So it should be prohibited.The double-free error message below prompted us to investigate:BUG: Bad page state in process swapper/1 pfn:0e0d1page:00000000c6548b28 refcount:-1 mapcount:0 mapping:0000000000000000index:0x2 pfn:0xe0d1flags: 0xfffffc0000000(node=0|zone=1|lastcpupid=0x1fffff)raw: 000fffffc0000000 0000000000000000 ffffffff00000101 0000000000000000raw: 0000000000000002 0000000000000000 ffffffffffffffff 0000000000000000page dumped because: nonzero _refcountCPU: 1 PID: 0 Comm: swapper/1 Tainted: G E 6.2.0+Call Trace: dump_stack_lvl+0x32/0x50bad_page+0x69/0xf0free_pcp_prepare+0x260/0x2f0free_unref_page+0x20/0x1c0skb_release_data+0x10b/0x1a0napi_consume_skb+0x56/0x150net_rx_action+0xf0/0x350? __napi_schedule+0x79/0x90__do_softirq+0xc8/0x2b1__irq_exit_rcu+0xb9/0xf0common_interrupt+0x82/0xa0asm_common_interrupt+0x22/0x40RIP: 0010:default_idle+0xb/0x20

CVE-2023-53188 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: openvswitch: fix race on port outputassume the following setup on a single machine:1. An openvswitch instance with one bridge and default flows2. two network namespaces "server" and "client"3. two ovs interfaces "server" and "client" on the bridge4. for each ovs interface a veth pair with a matching name and 32 rx and tx queues5. move the ends of the veth pairs to the respective network namespaces6. assign ip addresses to each of the veth ends in the namespaces (needs to be the same subnet)7. start some http server on the server network namespace8. test if a client in the client namespace can reach the http serverwhen following the actions below the host has a chance of getting a cpustuck in a infinite loop:1. send a large amount of parallel requests to the http server (around 3000 curls should work)2. in parallel delete the network namespace (do not delete interfaces or stop the server, just kill the namespace)there is a low chance that this will cause the below kernel cpu stuckmessage. If this does not happen just retry.Below there is also the output of bpftrace for the functions mentionedin the output.The series of events happening here is:1. the network namespace is deleted calling `unregister_netdevice_many_notify` somewhere in the process2. this sets first `NETREG_UNREGISTERING` on both ends of the veth and then runs `synchronize_net`3. it then calls `call_netdevice_notifiers` with `NETDEV_UNREGISTER`4. this is then handled by `dp_device_event` which calls `ovs_netdev_detach_dev` (if a vport is found, which is the case for the veth interface attached to ovs)5. this removes the rx_handlers of the device but does not prevent packages to be sent to the device6. `dp_device_event` then queues the vport deletion to work in background as a ovs_lock is needed that we do not hold in the unregistration path7. `unregister_netdevice_many_notify` continues to call `netdev_unregister_kobject` which sets `real_num_tx_queues` to 08. port deletion continues (but details are not relevant for this issue)9. at some future point the background task deletes the vportIf after 7. but before 9. a packet is send to the ovs vport (which isnot deleted at this point in time) which forwards it to the`dev_queue_xmit` flow even though the device is unregistering.In `skb_tx_hash` (which is called in the `dev_queue_xmit`) path there isa while loop (if the packet has a rx_queue recorded) that is infinite if`dev->real_num_tx_queues` is zero.To prevent this from happening we update `do_output` to handle deviceswithout carrier the same as if the device is not found (which wouldbe the code path after 9. is done).Additionally we now produce a warning in `skb_tx_hash` if we will hitthe infinite loop.bpftrace (first word is function name):__dev_queue_xmit server: real_num_tx_queues: 1, cpu: 2, pid: 28024, tid: 28024, skb_addr: 0xffff9edb6f207000, reg_state: 1netdev_core_pick_tx server: addr: 0xffff9f0a46d4a000 real_num_tx_queues: 1, cpu: 2, pid: 28024, tid: 28024, skb_addr: 0xffff9edb6f207000, reg_state: 1dp_device_event server: real_num_tx_queues: 1 cpu 9, pid: 21024, tid: 21024, event 2, reg_state: 1synchronize_rcu_expedited: cpu 9, pid: 21024, tid: 21024synchronize_rcu_expedited: cpu 9, pid: 21024, tid: 21024synchronize_rcu_expedited: cpu 9, pid: 21024, tid: 21024synchronize_rcu_expedited: cpu 9, pid: 21024, tid: 21024dp_device_event server: real_num_tx_queues: 1 cpu 9, pid: 21024, tid: 21024, event 6, reg_state: 2ovs_netdev_detach_dev server: real_num_tx_queues: 1 cpu 9, pid: 21024, tid: 21024, reg_state: 2netdev_rx_handler_unregister server: real_num_tx_queues: 1, cpu: 9, pid: 21024, tid: 21024, reg_state: 2synchronize_rcu_expedited: cpu 9, pid: 21024, tid: 21024netdev_rx_handler_unregister ret server: real_num_tx_queues: 1, cpu: 9, pid: 21024, tid: 21024, reg_state: 2dp_---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:vxlan: Fix nexthop hash sizeThe nexthop code expects a 31 bit hash, such as what is returned byfib_multipath_hash() and rt6_multipath_hash().

CVE-2023-53218 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: Make it so that a waiting process can be abortedWhen sendmsg() creates an rxrpc call, it queues it to wait for a connectionand channel to be assigned and then waits before it can start shovellingdata as the encrypted DATA packet content includes a summary of theconnection parameters.However, sendmsg() may get interrupted before a connection gets assignedand further sendmsg() calls will fail with EBUSY until an assignment ismade.Fix this so that the call can at least be aborted without failing onEBUSY. We have to be careful here as sendmsg() mustn't be allowed to startthe call timer if the call doesn't yet have a connection assigned as anoops may follow shortly thereafter.

CVE-2023-53224 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: Fix function prototype mismatch for ext4_feat_ktypeWith clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),indirect call targets are validated against the expected functionpointer prototype to make sure the call target is valid to help mitigateROP attacks. If they are not identical, there is a failure at run time,which manifests as either a kernel panic or thread getting killed.ext4_feat_ktype was setting the "release" handler to "kfree", whichdoesn't have a matching function prototype. Add a simple wrapperwith the correct prototype.This was found as a result of Clang's new -Wcast-function-type-strictflag, which is more sensitive than the simpler -Wcast-function-type,which only checks for type width mismatches.Note that this code is only reached when ext4 is a loadable module andit is being unloaded: CFI failure at kobject_put+0xbb/0x1b0 (target: kfree+0x0/0x180; expected type: 0x7c4aa698) ...

CVE-2023-53231 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:erofs: Fix detection of atomic contextCurrent check for atomic context is not sufficient asz_erofs_decompressqueue_endio can be called under rcu lockfrom blk_mq_flush_plug_list(). See the stacktrace [1]In such case we should hand off the decompression work for asyncprocessing rather than trying to do sync decompression in currentcontext. Patch fixes the detection by checking forrcu_read_lock_any_held() and while at it use more appropriate!in_task() check than in_atomic().Background: Historically erofs would always schedule a kworker fordecompression which would incur the scheduling cost regardless ofthe context. But z_erofs_decompressqueue_endio() may not alwaysbe in atomic context and we could actually benefit from doing thedecompression in z_erofs_decompressqueue_endio() if we are inthread context, for example when running with dm-verity.This optimization was later added in patch [2] which has shownimprovement in performance benchmarks.==============================================[1] Problem stacktrace[name:core&]BUG: sleeping function called from invalid context at kernel/locking/mutex.c:291[name:core&]in_atomic(): 0, irqs_disabled(): 0, non_block: 0, pid: 1615, name: CpuMonitorServi[name:core&]preempt_count: 0, expected: 0[name:core&]RCU nest depth: 1, expected: 0CPU: 7 PID: 1615 Comm: CpuMonitorServi Tainted: G S W OE 6.1.25-android14-5-maybe-dirty-mainline #1Hardware name: MT6897 (DT)Call trace: dump_backtrace+0x108/0x15c show_stack+0x20/0x30 dump_stack_lvl+0x6c/0x8c dump_stack+0x20/0x48 __might_resched+0x1fc/0x308 __might_sleep+0x50/0x88 mutex_lock+0x2c/0x110 z_erofs_decompress_queue+0x11c/0xc10 z_erofs_decompress_kickoff+0x110/0x1a4 z_erofs_decompressqueue_endio+0x154/0x180 bio_endio+0x1b0/0x1d8 __dm_io_complete+0x22c/0x280 clone_endio+0xe4/0x280 bio_endio+0x1b0/0x1d8 blk_update_request+0x138/0x3a4 blk_mq_plug_issue_direct+0xd4/0x19c blk_mq_flush_plug_list+0x2b0/0x354 __blk_flush_plug+0x110/0x160 blk_finish_plug+0x30/0x4c read_pages+0x2fc/0x370 page_cache_ra_unbounded+0xa4/0x23c page_cache_ra_order+0x290/0x320 do_sync_mmap_readahead+0x108/0x2c0 filemap_fault+0x19c/0x52c __do_fault+0xc4/0x114 handle_mm_fault+0x5b4/0x1168 do_page_fault+0x338/0x4b4 do_translation_fault+0x40/0x60 do_mem_abort+0x60/0xc8 el0_da+0x4c/0xe0 el0t_64_sync_handler+0xd4/0xfc el0t_64_sync+0x1a0/0x1a4[2] Link: https://lore.kernel.org/all/20210317035448.13921-1-huangjianan@oppo.com/

However between theread and re-locking the page we could have called release_folio() on thepage, but left the page in the file mapping. release_folio() can clearthe page private, and thus further down we blow up when we go to modifythe subpage bits.Fix this by putting the set_page_extent_mapped() after the read. Thisis safe because read_folio() will call set_page_extent_mapped() beforeit does the read, and then if we clear page private but leave it on themapping we're completely safe re-setting set_page_extent_mapped(). Withthis patch I can now run generic/476 without panicing.

CVE-2023-53308 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: fec: Better handle pm_runtime_get() failing in .remove()In the (unlikely) event that pm_runtime_get() (disguised aspm_runtime_resume_and_get()) fails, the remove callback returned anerror early. The problem with this is that the driver core ignores theerror value and continues removing the device. This results in aresource leak. Worse the devm allocated resources are freed and so if acallback of the driver is called later the register mapping is alreadygone which probably results in a crash.

CVE-2023-53347 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5: Handle pairing of E-switch via uplink un/load APIsIn case user switch a device from switchdev mode to legacy mode, mlx5first unpair the E-switch and afterwards unload the uplink vport.From the other hand, in case user remove or reload a device, mlx5first unload the uplink vport and afterwards unpair the E-switch.The latter is causing a bug[1], hence, handle pairing of E-switch aspart of uplink un/load APIs.[1]In case VF_LAG is used, every tc fdb flow is duplicated to the peeresw. However, the original esw keeps a pointer to this duplicatedflow, not the peer esw.e.g.: if user create tc fdb flow over esw0, the flow is duplicatedover esw1, in FW/HW, but in SW, esw0 keeps a pointer to the duplicatedflow.During module unload while a peer tc fdb flow is still offloaded, incase the first device to be removed is the peer device (esw1 in theexample above), the peer net-dev is destroyed, and so the mlx5e_privis memset to 0.Afterwards, the peer device is trying to unpair himself from theoriginal device (esw0 in the example above). Unpair API invoke theoriginal device to clear peer flow from its eswitch (esw0), but thepeer flow, which is stored over the original eswitch (esw0), istrying to use the peer mlx5e_priv, which is memset to 0 and result inbellow kernel-oops.[ 157.964081 ] BUG: unable to handle page fault for address: 000000000002ce60[ 157.964662 ] #PF: supervisor read access in kernel mode[ 157.965123 ] #PF: error_code(0x0000) - not-present page[ 157.965582 ] PGD 0 P4D 0[ 157.965866 ] Oops: 0000 [#1] SMP[ 157.967670 ] RIP: 0010:mlx5e_tc_del_fdb_flow+0x48/0x460 [mlx5_core][ 157.976164 ] Call Trace:[ 157.976437 ] [ 157.976690 ] __mlx5e_tc_del_fdb_peer_flow+0xe6/0x100 [mlx5_core][ 157.977230 ] mlx5e_tc_clean_fdb_peer_flows+0x67/0x90 [mlx5_core][ 157.977767 ] mlx5_esw_offloads_unpair+0x2d/0x1e0 [mlx5_core][ 157.984653 ] mlx5_esw_offloads_devcom_event+0xbf/0x130 [mlx5_core][ 157.985212 ] mlx5_devcom_send_event+0xa3/0xb0 [mlx5_core][ 157.985714 ] esw_offloads_disable+0x5a/0x110 [mlx5_core][ 157.986209 ] mlx5_eswitch_disable_locked+0x152/0x170 [mlx5_core][ 157.986757 ] mlx5_eswitch_disable+0x51/0x80 [mlx5_core][ 157.987248 ] mlx5_unload+0x2a/0xb0 [mlx5_core][ 157.987678 ] mlx5_uninit_one+0x5f/0xd0 [mlx5_core][ 157.988127 ] remove_one+0x64/0xe0 [mlx5_core][ 157.988549 ] pci_device_remove+0x31/0xa0[ 157.988933 ] device_release_driver_internal+0x18f/0x1f0[ 157.989402 ] driver_detach+0x3f/0x80[ 157.989754 ] bus_remove_driver+0x70/0xf0[ 157.990129 ] pci_unregister_driver+0x34/0x90[ 157.990537 ] mlx5_cleanup+0xc/0x1c [mlx5_core][ 157.990972 ] __x64_sys_delete_module+0x15a/0x250[ 157.991398 ] ? exit_to_user_mode_prepare+0xea/0x110[ 157.991840 ] do_syscall_64+0x3d/0x90[ 157.992198 ] entry_SYSCALL_64_after_hwframe+0x46/0xb0

Description: In the Linux kernel, the following vulnerability has been resolved:accel/habanalabs: postpone mem_mgr IDR destruction to hpriv_release()The memory manager IDR is currently destroyed when user releases thefile descriptor.However, at this point the user context might be still held, and memorybuffers might be still in use.Later on, calls to release those buffers will fail due to not findingtheir handles in the IDR, leading to a memory leak.To avoid this leak, split the IDR destruction from the memory managerfini, and postpone it to hpriv_release() when there is no user contextand no buffers are used.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: mpi3mr: Use number of bits to manage bitmap sizesTo allocate bitmaps, the mpi3mr driver calculates sizes of bitmaps usingbyte as unit. However, bitmap helper functions assume that bitmaps areallocated using unsigned long as unit. This gap causes memory access beyondthe bitmap sizes and results in "BUG: KASAN: slab-out-of-bounds". The BUGwas observed at firmware download to eHBA-9600. Call trace indicated thatthe out-of-bounds access happened in find_first_zero_bit() called frommpi3mr_send_event_ack() for miroc->evtack_cmds_bitmap.To fix the BUG, do not use bytes to manage bitmap sizes. Instead, usenumber of bits, and call bitmap helper functions which take number of bitsas arguments. For memory allocation, call bitmap_zalloc() instead ofkzalloc() and krealloc(). For memory free, call bitmap_free() instead ofkfree(). For zero clear, call bitmap_clear() instead of memset().Remove three fields for bitmap byte sizes in struct scmd_priv which are nolonger required. Replace the field dev_handle_bitmap_sz withdev_handle_bitmap_bits to keep number of bits of removepend_bitmap acrossresize.

CVE-2023-53383 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:irqchip/gicv3: Workaround for NVIDIA erratum T241-FABRIC-4The T241 platform suffers from the T241-FABRIC-4 erratum which causesunexpected behavior in the GIC when multiple transactions are receivedsimultaneously from different sources. This hardware issue impactsNVIDIA server platforms that use more than two T241 chipsinterconnected. Each chip has support for 320 {E}SPIs.This issue occurs when multiple packets from different GICs areincorrectly interleaved at the target chip. The erratum text belowspecifies exactly what can cause multiple transfer packets susceptibleto interleaving and GIC state corruption. GIC state corruption canlead to a range of problems, including kernel panics, and unexpectedbehavior.>From the erratum text: "In some cases, inter-socket AXI4 Stream packets with multiple transfers, may be interleaved by the fabric when presented to ARM Generic Interrupt Controller. GIC expects all transfers of a packet to be delivered without any interleaving. The following GICv3 commands may result in multiple transfer packets over inter-socket AXI4 Stream interface: - Register reads from GICD_I* and GICD_N* - Register writes to 64-bit GICD registers other than GICD_IROUTERn* - ITS command MOVALL Multiple commands in GICv4+ utilize multiple transfer packets, including VMOVP, VMOVI, VMAPP, and 64-bit register accesses." This issue impacts system configurations with more than 2 sockets, that require multi-transfer packets to be sent over inter-socket AXI4 Stream interface between GIC instances on different sockets. GICv4 cannot be supported. GICv3 SW model can only be supported with the workaround. Single and Dual socket configurations are not impacted by this issue and support GICv3 and GICv4."Writing to the chip alias region of the GICD_In{E} registers exceptGICD_ICENABLERn has an equivalent effect as writing to the globaldistributor. The SPI interrupt deactivate path is not impacted bythe erratum.To fix this problem, implement a workaround that ensures read accessesto the GICD_In{E} registers are directed to the chip that owns theSPI, and disable GICv4.x features. To simplify code changes, thegic_configure_irq() function uses the same alias region for both readand write operations to GICD_ICFGR.

CVE-2023-53421 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:blk-cgroup: Reinit blkg_iostat_set after clearing in blkcg_reset_stats()When blkg_alloc() is called to allocate a blkcg_gq structurewith the associated blkg_iostat_set's, there are 2 fields withinblkg_iostat_set that requires proper initialization - blkg & sync.The former field was introduced by commit 3b8cc6298724 ("blk-cgroup:Optimize blkcg_rstat_flush()") while the later one was introduced bycommit f73316482977 ("blk-cgroup: reimplement basic IO stats usingcgroup rstat").Unfortunately those fields in the blkg_iostat_set's are not properlyre-initialized when they are cleared in v1's blkcg_reset_stats(). Thiscan lead to a kernel panic due to NULL pointer access of the blkgpointer. The missing initialization of sync is less problematic andcan be a problem in a debug kernel due to missing lockdep initialization.Fix these problems by re-initializing them after memory clearing.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: don't check PageError in __extent_writepage__extent_writepage currenly sets PageError whenever any error happens,and the also checks for PageError to decide if to call error handling.This leads to very unclear responsibility for cleaning up on errors.In the VM and generic writeback helpers the basic idea is that onceI/O is fired off all error handling responsibility is delegated to theend I/O handler. But if that end I/O handler sets the PageError bit,and the submitter checks it, the bit could in some cases leak into thesubmission context for fast enough I/O.Fix this by simply not checking PageError and just using the localret variable to check for submission errors. This also fundamentallysolves the long problem documented in a comment in __extent_writepageby never leaking the error bit into the submission context.

CVE-2023-53461 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring: wait interruptibly for request completions on exitWHen the ring exits, cleanup is done and the final cancelation andwaiting on completions is done by io_ring_exit_work. That function isinvoked by kworker, which doesn't take any signals. Because of that, itdoesn't really matter if we wait for completions in TASK_INTERRUPTIBLEor TASK_UNINTERRUPTIBLE state. However, it does matter to the hung taskdetection checker!Normally we expect cancelations and completions to happen ratherquickly. Some test cases, however, will exit the ring and park theowning task stopped (eg via SIGSTOP). If the owning task needs to runtask_work to complete requests, then io_ring_exit_work won't make anyprogress until the task is runnable again. Hence io_ring_exit_work cantrigger the hung task detection, which is particularly problematic ifpanic-on-hung-task is enabled.As the ring exit doesn't take signals to begin with, have it waitinterruptibly rather than uninterruptibly. io_uring has a separatestuck-exit warning that triggers independently anyway, so we're notreally missing anything by making this switch.

CVE-2023-53489 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:tcp/udp: Fix memleaks of sk and zerocopy skbs with TX timestamp.syzkaller reported [0] memory leaks of an UDP socket and ZEROCOPYskbs. We can reproduce the problem with these sequences: sk = socket(AF_INET, SOCK_DGRAM, 0) sk.setsockopt(SOL_SOCKET, SO_TIMESTAMPING, SOF_TIMESTAMPING_TX_SOFTWARE) sk.setsockopt(SOL_SOCKET, SO_ZEROCOPY, 1) sk.sendto(b'', MSG_ZEROCOPY, ('127.0.0.1', 53)) sk.close()sendmsg() calls msg_zerocopy_alloc(), which allocates a skb, setsskb->cb->ubuf.refcnt to 1, and calls sock_hold(). Here, structubuf_info_msgzc indirectly holds a refcnt of the socket. When theskb is sent, __skb_tstamp_tx() clones it and puts the clone intothe socket's error queue with the TX timestamp.When the original skb is received locally, skb_copy_ubufs() callsskb_unclone(), and pskb_expand_head() increments skb->cb->ubuf.refcnt.This additional count is decremented while freeing the skb, but structubuf_info_msgzc still has a refcnt, so __msg_zerocopy_callback() isnot called.The last refcnt is not released unless we retrieve the TX timestampedskb by recvmsg(). Since we clear the error queue in inet_sock_destruct()after the socket's refcnt reaches 0, there is a circular dependency.If we close() the socket holding such skbs, we never call sock_put()and leak the count, sk, and skb.TCP has the same problem, and commit e0c8bccd40fc ("net: stream:purge sk_error_queue in sk_stream_kill_queues()") tried to fix itby calling skb_queue_purge() during close(). However, there is asmall chance that skb queued in a qdisc or device could be putinto the error queue after the skb_queue_purge() call.In __skb_tstamp_tx(), the cloned skb should not have a referenceto the ubuf to remove the circular dependency, but skb_clone() doesnot call skb_copy_ubufs() for zerocopy skb. So, we need to callskb_orphan_frags_rx() for the cloned skb to call skb_copy_ubufs().[0]:BUG: memory leakunreferenced object 0xffff88800c6d2d00 (size 1152): comm "syz-executor392", pid 264, jiffies 4294785440 (age 13.044s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 cd af e8 81 00 00 00 00 ................ 02 00 07 40 00 00 00 00 00 00 00 00 00 00 00 00 ...@............ backtrace: [<0000000055636812>] sk_prot_alloc+0x64/0x2a0 net/core/sock.c:2024 [<0000000054d77b7a>] sk_alloc+0x3b/0x800 net/core/sock.c:2083 [<0000000066f3c7e0>] inet_create net/ipv4/af_inet.c:319 [inline] [<0000000066f3c7e0>] inet_create+0x31e/0xe40 net/ipv4/af_inet.c:245 [<000000009b83af97>] __sock_create+0x2ab/0x550 net/socket.c:1515 [<00000000b9b11231>] sock_create net/socket.c:1566 [inline] [<00000000b9b11231>] __sys_socket_create net/socket.c:1603 [inline] [<00000000b9b11231>] __sys_socket_create net/socket.c:1588 [inline] [<00000000b9b11231>] __sys_socket+0x138/0x250 net/socket.c:1636 [<000000004fb45142>] __do_sys_socket net/socket.c:1649 [inline] [<000000004fb45142>] __se_sys_socket net/socket.c:1647 [inline] [<000000004fb45142>] __x64_sys_socket+0x73/0xb0 net/socket.c:1647 [<0000000066999e0e>] do_syscall_x64 arch/x86/entry/common.c:50 [inline] [<0000000066999e0e>] do_syscall_64+0x38/0x90 arch/x86/entry/common.c:80 [<0000000017f238c1>] entry_SYSCALL_64_after_hwframe+0x63/0xcdBUG: memory leakunreferenced object 0xffff888017633a00 (size 240): comm "syz-executor392", pid 264, jiffies 4294785440 (age 13.044s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 2d 6d 0c 80 88 ff ff .........-m..... backtrace: [<000000002b1c4368>] __alloc_skb+0x229/0x320 net/core/skbuff.c:497 [<00000000143579a6>] alloc_skb include/linux/skbuff.h:1265 [inline] [<00000000143579a6>] sock_omalloc+0xaa/0x190 net/core/sock.c:2596 [<00000000be626478>] msg_zerocopy_alloc net/core/skbuff.c:1294 [inline] [<00000000be626478>]---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: ipset: Rework long task execution when adding/deleting entriesWhen adding/deleting large number of elements in one step in ipset, it cantake a reasonable amount of time and can result in soft lockup errors. Thepatch 5f7b51bf09ba ("netfilter: ipset: Limit the maximal range ofconsecutive elements to add/delete") tried to fix it by limiting the maxelements to process at all. However it was not enough, it is still possiblethat we get hung tasks. Lowering the limit is not reasonable, so theapproach in this patch is as follows: rely on the method used at resizingsets and save the state when we reach a smaller internal batch limit,unlock/lock and proceed from the saved state. Thus we can avoid longcontinuous tasks and at the same time removed the limit to add/delete largenumber of elements in one step.The nfnl mutex is held during the whole operation which prevents one toissue other ipset commands in parallel.

So when __cpu_map_ring_cleanup() checksthe ptr_ring, it will find it was not emptied and report a warning.An alternative fix is to use __cpu_map_ring_cleanup() to drop thesepending frames or skbs when kthread_stop() returns -EINTR, but it mayconfuse the user, because these frames or skbs have been handledcorrectly by XDP program. So instead of dropping these frames or skbs,just make sure the per-cpu kthread is running before__cpu_map_entry_alloc() returns.After apply the fix, the error handle for kthread_stop() will beunnecessary because it will always return 0, so just remove it.

And skb->len equals to size in qrtr_endpoint_post().But size is less than sizeof(struct qrtr_ctrl_pkt) when qrtr_cb->typeequals to QRTR_TYPE_RESUME_TX in qrtr_endpoint_post() under the syzbotscenario. This triggers the uninit variable access bug.Add size check when qrtr_cb->type equals to QRTR_TYPE_RESUME_TX inqrtr_endpoint_post() to fix the bug.

CVE-2023-53580 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:USB: Gadget: core: Help prevent panic during UVC unconfigureAvichal Rakesh reported a kernel panic that occurred when the UVCgadget driver was removed from a gadget's configuration. The panicinvolves a somewhat complicated interaction between the kernel driverand a userspace component (as described in the Link tag below), butthe analysis did make one thing clear: The Gadget core shouldaccomodate gadget drivers calling usb_gadget_deactivate() as part oftheir unbind procedure.Currently this doesn't work. gadget_unbind_driver() callsdriver->unbind() while holding the udc->connect_lock mutex, andusb_gadget_deactivate() attempts to acquire that mutex, which willresult in a deadlock.The simple fix is for gadget_unbind_driver() to release the mutex wheninvoking the ->unbind() callback. There is no particular reason forit to be holding the mutex at that time, and the mutex isn't heldwhile the ->bind() callback is invoked. So we'll drop the mutexbefore performing the unbind callback and reacquire it afterward.We'll also add a couple of comments to usb_gadget_activate() andusb_gadget_deactivate(). Because they run in process context theymust not be called from a gadget driver's ->disconnect() callback,which (according to the kerneldoc for struct usb_gadget_driver ininclude/linux/usb/gadget.h) may run in interrupt context. This mayhelp prevent similar bugs from arising in the future.

CVE-2023-53591 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5e: Fix deadlock in tc route query codeCited commit causes ABBA deadlock[0] when peer flows are created whileholding the devcom rw semaphore. Due to peer flows offload implementationthe lock is taken much higher up the call chain and there is no obvious wayto easily fix the deadlock. Instead, since tc route query code needs thepeer eswitch structure only to perform a lookup in xarray and doesn'tperform any sleeping operations with it, refactor the code for locklessexecution in following ways:- RCUify the devcom 'data' pointer. When resetting the pointersynchronously wait for RCU grace period before returning. This is finesince devcom is currently only used for synchronization ofpairing/unpairing of eswitches which is rare and already expensive as-is.- Wrap all usages of 'paired' boolean in {READ|WRITE}_ONCE(). The flag hasalready been used in some unlocked contexts without properannotations (e.g. users of mlx5_devcom_is_paired() function), but it wasn'tan issue since all relevant code paths checked it again after obtaining thedevcom semaphore. Now it is also used by mlx5_devcom_get_peer_data_rcu() as"best effort" check to return NULL when devcom is being unpaired. Note thatwhile RCU read lock doesn't prevent the unpaired flag from being changedconcurrently it still guarantees that reader can continue to use 'data'.- Refactor mlx5e_tc_query_route_vport() function to use newmlx5_devcom_get_peer_data_rcu() API which fixes the deadlock.[0]:[ 164.599612] ======================================================[ 164.600142] WARNING: possible circular locking dependency detected[ 164.600667] 6.3.0-rc3+ #1 Not tainted[ 164.601021] ------------------------------------------------------[ 164.601557] handler1/3456 is trying to acquire lock:[ 164.601998] ffff88811f1714b0 (&esw->offloads.encap_tbl_lock){+.+.}-{3:3}, at: mlx5e_attach_encap+0xd8/0x8b0 [mlx5_core][ 164.603078] but task is already holding lock:[ 164.603617] ffff88810137fc98 (&comp->sem){++++}-{3:3}, at: mlx5_devcom_get_peer_data+0x37/0x80 [mlx5_core][ 164.604459] which lock already depends on the new lock.[ 164.605190] the existing dependency chain (in reverse order) is:[ 164.605848] -> #1 (&comp->sem){++++}-{3:3}:[ 164.606380] down_read+0x39/0x50[ 164.606772] mlx5_devcom_get_peer_data+0x37/0x80 [mlx5_core][ 164.607336] mlx5e_tc_query_route_vport+0x86/0xc0 [mlx5_core][ 164.607914] mlx5e_tc_tun_route_lookup+0x1a4/0x1d0 [mlx5_core][ 164.608495] mlx5e_attach_decap_route+0xc6/0x1e0 [mlx5_core][ 164.609063] mlx5e_tc_add_fdb_flow+0x1ea/0x360 [mlx5_core][ 164.609627] __mlx5e_add_fdb_flow+0x2d2/0x430 [mlx5_core][ 164.610175] mlx5e_configure_flower+0x952/0x1a20 [mlx5_core][ 164.610741] tc_setup_cb_add+0xd4/0x200[ 164.611146] fl_hw_replace_filter+0x14c/0x1f0 [cls_flower][ 164.611661] fl_change+0xc95/0x18a0 [cls_flower][ 164.612116] tc_new_tfilter+0x3fc/0xd20[ 164.612516] rtnetlink_rcv_msg+0x418/0x5b0[ 164.612936] netlink_rcv_skb+0x54/0x100[ 164.613339] netlink_unicast+0x190/0x250[ 164.613746] netlink_sendmsg+0x245/0x4a0[ 164.614150] sock_sendmsg+0x38/0x60[ 164.614522] ____sys_sendmsg+0x1d0/0x1e0[ 164.614934] ___sys_sendmsg+0x80/0xc0[ 164.615320] __sys_sendmsg+0x51/0x90[ 164.615701] do_syscall_64+0x3d/0x90[ 164.616083] entry_SYSCALL_64_after_hwframe+0x46/0xb0[ 164.616568] -> #0 (&esw->offloads.encap_tbl_lock){+.+.}-{3:3}:[ 164.617210] __lock_acquire+0x159e/0x26e0[ 164.617638] lock_acquire+0xc2/0x2a0[ 164.618018] __mutex_lock+0x92/0xcd0[ 164.618401] mlx5e_attach_encap+0xd8/0x8b0 [mlx5_core][ 164.618943] post_process_attr+0x153/0x2d0 [---truncated---

CVE-2023-53596 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:drivers: base: Free devm resources when unregistering a deviceIn the current code, devres_release_all() only gets called if the devicehas a bus and has been probed.This leads to issues when using bus-less or driver-less devices wherethe device might never get freed if a managed resource holds a referenceto the device. This is happening in the DRM framework for example.We should thus call devres_release_all() in the device_del() function tomake sure that the device-managed actions are properly executed when thedevice is unregistered, even if it has neither a bus nor a driver.This is effectively the same change than commit 2f8d16a996da ("devres:release resources on device_del()") that got reverted by commita525a3ddeaca ("driver core: free devres in device_release") overmemory leaks concerns.This patch effectively combines the two commits mentioned above torelease the resources both on device_del() and device_release() and getthe best of both worlds.

CVE-2023-53647 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:Drivers: hv: vmbus: Don't dereference ACPI root object handleSince the commit referenced in the Fixes: tag below the VMBus client driveris walking the ACPI namespace up from the VMBus ACPI device to the ACPInamespace root object trying to find Hyper-V MMIO ranges.However, if it is not able to find them it ends trying to walk resources ofthe ACPI namespace root object itself.This object has all-ones handle, which causes a NULL pointer dereferencein the ACPI code (from dereferencing this pointer with an offset).This in turn causes an oops on boot with VMBus host implementations that donot provide Hyper-V MMIO ranges in their VMBus ACPI device or itsancestors.The QEMU VMBus implementation is an example of such implementation.I guess providing these ranges is optional, since all tested Windowsversions seem to be able to use VMBus devices without them.Fix this by explicitly terminating the lookup at the ACPI namespace rootobject.Note that Linux guests under KVM/QEMU do not use the Hyper-V PV interfaceby default - they only do so if the KVM PV interface is missing ordisabled.Example stack trace of such oops:[ 3.710827] ? __die+0x1f/0x60[ 3.715030] ? page_fault_oops+0x159/0x460[ 3.716008] ? exc_page_fault+0x73/0x170[ 3.716959] ? asm_exc_page_fault+0x22/0x30[ 3.717957] ? acpi_ns_lookup+0x7a/0x4b0[ 3.718898] ? acpi_ns_internalize_name+0x79/0xc0[ 3.720018] acpi_ns_get_node_unlocked+0xb5/0xe0[ 3.721120] ? acpi_ns_check_object_type+0xfe/0x200[ 3.722285] ? acpi_rs_convert_aml_to_resource+0x37/0x6e0[ 3.723559] ? down_timeout+0x3a/0x60[ 3.724455] ? acpi_ns_get_node+0x3a/0x60[ 3.725412] acpi_ns_get_node+0x3a/0x60[ 3.726335] acpi_ns_evaluate+0x1c3/0x2c0[ 3.727295] acpi_ut_evaluate_object+0x64/0x1b0[ 3.728400] acpi_rs_get_method_data+0x2b/0x70[ 3.729476] ? vmbus_platform_driver_probe+0x1d0/0x1d0 [hv_vmbus][ 3.730940] ? vmbus_platform_driver_probe+0x1d0/0x1d0 [hv_vmbus][ 3.732411] acpi_walk_resources+0x78/0xd0[ 3.733398] vmbus_platform_driver_probe+0x9f/0x1d0 [hv_vmbus][ 3.734802] platform_probe+0x3d/0x90[ 3.735684] really_probe+0x19b/0x400[ 3.736570] ? __device_attach_driver+0x100/0x100[ 3.737697] __driver_probe_device+0x78/0x160[ 3.738746] driver_probe_device+0x1f/0x90[ 3.739743] __driver_attach+0xc2/0x1b0[ 3.740671] bus_for_each_dev+0x70/0xc0[ 3.741601] bus_add_driver+0x10e/0x210[ 3.742527] driver_register+0x55/0xf0[ 3.744412] ? 0xffffffffc039a000[ 3.745207] hv_acpi_init+0x3c/0x1000 [hv_vmbus]

Description: In the Linux kernel, the following vulnerability has been resolved:mt76: mt7921: don't assume adequate headroom for SDIO headersmt7921_usb_sdio_tx_prepare_skb() calls mt7921_usb_sdio_write_txwi() andmt7921_skb_add_usb_sdio_hdr(), both of which blindly assume thatadequate headroom will be available in the passed skb. This assumptiontypically is satisfied when the skb was allocated in the net core fortransmission via the mt7921 netdev (although even that is only anoptimization and is not strictly guaranteed), but the assumption issometimes not satisfied when the skb originated in the receive path ofanother netdev and was passed through to the mt7921, such as by thebridge layer. Blindly prepending bytes to an skb is always wrong.This commit introduces a call to skb_cow_head() before the call tomt7921_usb_sdio_write_txwi() in mt7921_usb_sdio_tx_prepare_skb() toensure that at least MT_SDIO_TXD_SIZE + MT_SDIO_HDR_SIZE bytes can bepushed onto the skb.Without this fix, I can trivially cause kernel panics by bridging anMT7921AU-based USB 802.11ax interface with an Ethernet interface on anIntel Atom-based x86 system using its onboard RTL8169 PCI Ethernetadapter and also on an ARM-based Raspberry Pi 1 using its onboardSMSC9512 USB Ethernet adapter. Note that the panics do not occur inevery system configuration, as they occur only if the receiving netdevleaves less headroom in its received skbs than the mt7921 needs for itsSDIO headers.Here is an example stack trace of this panic on Raspberry Pi OS Lite2023-02-21 running kernel 6.1.24+ [1]: skb_panic from skb_push+0x44/0x48 skb_push from mt7921_usb_sdio_tx_prepare_skb+0xd4/0x190 [mt7921_common] mt7921_usb_sdio_tx_prepare_skb [mt7921_common] from mt76u_tx_queue_skb+0x94/0x1d0 [mt76_usb] mt76u_tx_queue_skb [mt76_usb] from __mt76_tx_queue_skb+0x4c/0xc8 [mt76] __mt76_tx_queue_skb [mt76] from mt76_txq_schedule.part.0+0x13c/0x398 [mt76] mt76_txq_schedule.part.0 [mt76] from mt76_txq_schedule_all+0x24/0x30 [mt76] mt76_txq_schedule_all [mt76] from mt7921_tx_worker+0x58/0xf4 [mt7921_common] mt7921_tx_worker [mt7921_common] from __mt76_worker_fn+0x9c/0xec [mt76] __mt76_worker_fn [mt76] from kthread+0xbc/0xe0 kthread from ret_from_fork+0x14/0x34After this fix, bridging the mt7921 interface works fine on both of mypreviously problematic systems.[1] https://github.com/raspberrypi/firmware/tree/5c276f55a4b21345cd4d6200a504ee991851ff7a

Description: In the Linux kernel, the following vulnerability has been resolved:ethtool: Fix uninitialized number of lanesIt is not possible to set the number of lanes when setting link modesusing the legacy IOCTL ethtool interface. Since 'structethtool_link_ksettings' is not initialized in this path, drivers receivean uninitialized number of lanes in 'structethtool_link_ksettings::lanes'.When this information is later queried from drivers, it results in theethtool code making decisions based on uninitialized memory, leading tothe following KMSAN splat [1]. In practice, this most likely onlyhappens with the tun driver that simply returns whatever it got in theset operation.As far as I can tell, this uninitialized memory is not leaked to userspace thanks to the 'ethtool_ops->cap_link_lanes_supported' check inlinkmodes_prepare_data().Fix by initializing the structure in the IOCTL path.

CVE-2023-53810 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:blk-mq: release crypto keyslot before reporting I/O completeOnce all I/O using a blk_crypto_key has completed, filesystems can callblk_crypto_evict_key(). However, the block layer currently doesn't callblk_crypto_put_keyslot() until the request is being freed, which happensafter upper layers have been told (via bio_endio()) the I/O hascompleted. This causes a race condition where blk_crypto_evict_key()can see 'slot_refs != 0' without there being an actual bug.This makes __blk_crypto_evict_key() hit the'WARN_ON_ONCE(atomic_read(&slot->slot_refs) != 0)' and return withoutdoing anything, eventually causing a use-after-free inblk_crypto_reprogram_all_keys(). (This is a very rare bug and has onlybeen seen when per-file keys are being used with fscrypt.)There are two options to fix this: either release the keyslot beforebio_endio() is called on the request's last bio, or make__blk_crypto_evict_key() ignore slot_refs. Let's go with the firstsolution, since it preserves the ability to report bugs (viaWARN_ON_ONCE) where a key is evicted while still in-use.

However, we haveyet to get such a report, and only syzkaller stumbled on it. So, thiscan be changed safely.Note this does not change SOCK_SEQPACKET behaviour.

CVE-2023-53834 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:iio: adc: ina2xx: avoid NULL pointer dereference on OF device matchThe affected lines were resulting in a NULL pointer dereference on ourplatform because the device tree contained the following list ofcompatible strings: power-sensor@40 { compatible = "ti,ina232", "ti,ina231"; ... };Since the driver doesn't declare a compatible string "ti,ina232", the OFmatching succeeds on "ti,ina231". But the I2C device ID info ispopulated via the first compatible string, cf. modalias population inof_i2c_get_board_info(). Since there is no "ina232" entry in the legacyI2C device ID table either, the struct i2c_device_id *id pointer in theprobe function is NULL.Fix this by using the already populated type variable instead, whichpoints to the proper driver data. Since the name is also wanted, add ageneric one to the ina2xx_config table.

CVE-2023-53836 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf, sockmap: Fix skb refcnt race after locking changesThere is a race where skb's from the sk_psock_backlog can be referencedafter userspace side has already skb_consumed() the sk_buff and its refcntdropped to zer0 causing use after free.The flow is the following: while ((skb = skb_peek(&psock->ingress_skb)) sk_psock_handle_Skb(psock, skb, ..., ingress) if (!ingress) ... sk_psock_skb_ingress sk_psock_skb_ingress_enqueue(skb) msg->skb = skb sk_psock_queue_msg(psock, msg) skb_dequeue(&psock->ingress_skb)The sk_psock_queue_msg() puts the msg on the ingress_msg queue. This iswhat the application reads when recvmsg() is called. An application canread this anytime after the msg is placed on the queue. The recvmsg hookwill also read msg->skb and then after user space reads the msg will callconsume_skb(skb) on it effectively free'ing it.But, the race is in above where backlog queue still has a reference tothe skb and calls skb_dequeue(). If the skb_dequeue happens after theuser reads and free's the skb we have a use after free.The !ingress case does not suffer from this problem because it usessendmsg_*(sk, msg) which does not pass the sk_buff further down thestack.The following splat was observed with 'test_progs -t sockmap_listen': [ 1022.710250][ T2556] general protection fault, ...

This bumps the skb->users refcnt so that consume_skb()and kfree_skb will not immediately free the sk_buff. With this we canbe sure the skb is still around when we do the dequeue. Then we justneed to decrement the refcnt or free the skb in the backlog case whichwe do by calling kfree_skb() on the ingress case as well as the sendmsgcase.Before locking change from fixes tag we had the sock locked so wecouldn't race with user and there was no issue here.

Description: In the Linux kernel, the following vulnerability has been resolved:usb-storage: alauda: Fix uninit-value in alauda_check_media()Syzbot got KMSAN to complain about access to an uninitialized value inthe alauda subdriver of usb-storage:BUG: KMSAN: uninit-value in alauda_transport+0x462/0x57f0drivers/usb/storage/alauda.c:1137CPU: 0 PID: 12279 Comm: usb-storage Not tainted 5.3.0-rc7+ #0Hardware name: Google Google Compute Engine/Google Compute Engine, BIOSGoogle 01/01/2011Call Trace: __dump_stack lib/dump_stack.c:77 [inline] dump_stack+0x191/0x1f0 lib/dump_stack.c:113 kmsan_report+0x13a/0x2b0 mm/kmsan/kmsan_report.c:108 __msan_warning+0x73/0xe0 mm/kmsan/kmsan_instr.c:250 alauda_check_media+0x344/0x3310 drivers/usb/storage/alauda.c:460The problem is that alauda_check_media() doesn't verify that its USBtransfer succeeded before trying to use the received data. Whatshould happen if the transfer fails isn't entirely clear, but areasonably conservative approach is to pretend that no media ispresent.A similar problem exists in a usb_stor_dbg() call inalauda_get_media_status(). In this case, when an error occurs thecall is redundant, because usb_stor_ctrl_transfer() already will printa debugging message.Finally, unrelated to the uninitialized memory access, is the factthat alauda_check_media() performs DMA to a buffer on the stack.Fortunately usb-storage provides a general purpose DMA-able buffer foruses like this. We'll use it instead.

CVE-2023-53856 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:of: overlay: Call of_changeset_init() earlyWhen of_overlay_fdt_apply() fails, the changeset may be partiallyapplied, and the caller is still expected to call of_overlay_remove() toclean up this partial state.However, of_overlay_apply() calls of_resolve_phandles() beforeinit_overlay_changeset(). Hence if the overlay fails to apply due to anunresolved symbol, the overlay_changeset.cset.entries list is stilluninitialized, and cleanup will crash with a NULL-pointer dereference inoverlay_removal_is_ok().Fix this by moving the call to of_changeset_init() frominit_overlay_changeset() to of_overlay_fdt_apply(), where all otherearly initialization is done.

CVE-2023-53989 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:arm64: mm: fix VA-range sanity checkBoth create_mapping_noalloc() and update_mapping_prot() sanity-checktheir 'virt' parameter, but the check itself doesn't make much sense.The condition used today appears to be a historical accident.The sanity-check condition: if ((virt >= PAGE_END) && (virt < VMALLOC_START)) { [ ... warning here ... ] return; }... can only be true for the KASAN shadow region or the module region,and there's no reason to exclude these specifically for creating andupdateing mappings.When arm64 support was first upstreamed in commit: c1cc1552616d0f35 ("arm64: MMU initialisation")... the condition was: if (virt < VMALLOC_START) { [ ... warning here ... ] return; }At the time, VMALLOC_START was the lowest kernel address, and this waschecking whether 'virt' would be translated via TTBR1.Subsequently in commit: 14c127c957c1c607 ("arm64: mm: Flip kernel VA space")... the condition was changed to: if ((virt >= VA_START) && (virt < VMALLOC_START)) { [ ... warning here ... ] return; }This appear to have been a thinko. The commit moved the linear map tothe bottom of the kernel address space, with VMALLOC_START being at thehalfway point. The old condition would warn for changes to the linearmap below this, and at the time VA_START was the end of the linear map.Subsequently we cleaned up the naming of VA_START in commit: 77ad4ce69321abbe ("arm64: memory: rename VA_START to PAGE_END")... keeping the erroneous condition as: if ((virt >= PAGE_END) && (virt < VMALLOC_START)) { [ ... warning here ... ] return; }Correct the condition to check against the start of the TTBR1 addressspace, which is currently PAGE_OFFSET. This simplifies the logic, andmore clearly matches the "outside kernel range" message in the warning.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/msm/dpu: Disallow unallocated resources to be returnedIn the event that the topology requests resources that have not beencreated by the system (because they are typically not represented indpu_mdss_cfg ^1), the resource(s) in global_state (in this case DSCblocks, until their allocation/assignment is being sanity-checked in"drm/msm/dpu: Reject topologies for which no DSC blocks are available")remain NULL but will still be returned out ofdpu_rm_get_assigned_resources, where the caller expects to get an arraycontaining num_blks valid pointers (but instead gets these NULLs).To prevent this from happening, where null-pointer dereferencestypically result in a hard-to-debug platform lockup, num_blks shouldn'tincrease past NULL blocks and will print an error and break instead.After all, max_blks represents the static size of the maximum number ofblocks whereas the actual amount varies per platform.^1: which can happen after a git rebase ended up moving additions to_dpu_cfg to a different struct which has the same patch context.Patchwork: https://patchwork.freedesktop.org/patch/517636/

Description: In the Linux kernel, the following vulnerability has been resolved:x86/sev: Make enc_dec_hypercall() accept a size instead of npagesenc_dec_hypercall() accepted a page count instead of a size, whichforced its callers to round up. As a result, non-page alignedvaddrs caused pages to be spuriously marked as decrypted via theencryption status hypercall, which in turn caused consistentcorruption of pages during live migration. Live migration requiresaccurate encryption status information to avoid migrating pagesfrom the wrong perspective.

CVE-2023-53998 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:hwrng: virtio - Fix race on data_avail and actual dataThe virtio rng device kicks off a new entropy request whenever thedata available reaches zero. When a new request occurs at the endof a read operation, that is, when the result of that request isonly needed by the next reader, then there is a race between thewriting of the new data and the next reader.This is because there is no synchronisation whatsoever between thewriter and the reader.Fix this by writing data_avail with smp_store_release and readingit with smp_load_acquire when we first enter read. The subsequentreads are safe because they're either protected by the first loadacquire, or by the completion mechanism.Also remove the redundant zeroing of data_idx in random_recv_done(data_idx must already be zero at this point) and data_avail inrequest_entropy (ditto).

Description: In the Linux kernel, the following vulnerability has been resolved:sched/psi: use kernfs polling functions for PSI trigger pollingDestroying psi trigger in cgroup_file_release causes UAF issues whena cgroup is removed from under a polling process. This is happeningbecause cgroup removal causes a call to cgroup_file_release while theactual file is still alive. Destroying the trigger at this point wouldalso destroy its waitqueue head and if there is still a polling processon that file accessing the waitqueue, it will step on the freed pointer:do_select vfs_poll do_rmdir cgroup_rmdir kernfs_drain_open_files cgroup_file_release cgroup_pressure_release psi_trigger_destroy wake_up_pollfree(&t->event_wait)// vfs_poll is unblocked synchronize_rcu kfree(t) poll_freewait -> UAF access to the trigger's waitqueue headPatch [1] fixed this issue for epoll() case using wake_up_pollfree(),however the same issue exists for synchronous poll() case.The root cause of this issue is that the lifecycles of the psi trigger'swaitqueue and of the file associated with the trigger are different. Fixthis by using kernfs_generic_poll function when polling on cgroup-specificpsi triggers. It internally uses kernfs_open_node->poll waitqueue headwith its lifecycle tied to the file's lifecycle. This also renders thefix in [1] obsolete, so revert it.[1] commit c2dbe32d5db5 ("sched/psi: Fix use-after-free in ep_remove_wait_queue()")

If balance completes and returns 0,but we have a pause or cancel request we won't do the appropriatecleanup, and then the next time we try to start a balance we'll tripthis ASSERT.The error handling is just wrong here, we always want to clean up,unless we got -ECANCELLED and we set the appropriate pause flag in theexclusive op. With this patch the reproducer ran for an hour withouttripping, previously it would trip in less than a few minutes.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: rsi: Do not configure WoWlan in shutdown hook if not enabledIn case WoWlan was never configured during the operation of the system,the hw->wiphy->wowlan_config will be NULL. rsi_config_wowlan() checkswhether wowlan_config is non-NULL and if it is not, then WARNs about it.The warning is valid, as during normal operation the rsi_config_wowlan()should only ever be called with non-NULL wowlan_config. In shutdown thisrsi_config_wowlan() should only ever be called if WoWlan was configuredbefore by the user.Add checks for non-NULL wowlan_config into the shutdown hook. While at it,check whether the wiphy is also non-NULL before accessing wowlan_config .Drop the single-use wowlan_config variable, just inline it into functioncall.

CVE-2023-54033 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: fix a memory leak in the LRU and LRU_PERCPU hash mapsThe LRU and LRU_PERCPU maps allocate a new element on update before locking thetarget hash table bucket. Right after that the maps try to lock the bucket.If this fails, then maps return -EBUSY to the caller without releasing theallocated element. This makes the element untracked: it doesn't belong toeither of free lists, and it doesn't belong to the hash table, so can't bere-used; this eventually leads to the permanent -ENOMEM on LRU map updates,which is unexpected. Fix this by returning the element to the local free listif bucket locking fails.

CVE-2023-54036 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: rtl8xxxu: Fix memory leaks with RTL8723BU, RTL8192EUThe wifi + bluetooth combo chip RTL8723BU can leak memory (especially?)when it's connected to a bluetooth audio device. The busy bluetoothtraffic generates lots of C2H (card to host) messages, which are notfreed correctly.To fix this, move the dev_kfree_skb() call in rtl8xxxu_c2hcmd_callback()inside the loop where skb_dequeue() is called.The RTL8192EU leaks memory because the C2H messages are added to thequeue and left there forever. (This was fine in the past because itprobably wasn't sending any C2H messages until commit e542e66b7c2e("wifi: rtl8xxxu: gen2: Turn on the rate control"). Since that commitit sends a C2H message when the TX rate changes.)To fix this, delete the check for rf_paths > 1 and the goto. Let thefunction process the C2H messages from RTL8192EU like the ones fromthe other chips.Theoretically the RTL8188FU could also leak like RTL8723BU, but itmost likely doesn't send C2H messages frequently enough.This change was tested with RTL8723BU by Erhard F. I tested it withRTL8188FU and RTL8192EU.

CVE-2023-54039 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:can: j1939: j1939_tp_tx_dat_new(): fix out-of-bounds memory accessIn the j1939_tp_tx_dat_new() function, an out-of-bounds memory accesscould occur during the memcpy() operation if the size of skb->cb islarger than the size of struct j1939_sk_buff_cb. This is because thememcpy() operation uses the size of skb->cb, leading to a read beyondthe struct j1939_sk_buff_cb.Updated the memcpy() operation to use the size of structj1939_sk_buff_cb instead of the size of skb->cb. This ensures that thememcpy() operation only reads the memory within the bounds of structj1939_sk_buff_cb, preventing out-of-bounds memory access.Additionally, add a BUILD_BUG_ON() to check that the size of skb->cbis greater than or equal to the size of struct j1939_sk_buff_cb. Thisensures that the skb->cb buffer is large enough to hold thej1939_sk_buff_cb structure.[mkl: rephrase commit message]

Description: In the Linux kernel, the following vulnerability has been resolved:ubifs: Fix memleak when insert_old_idx() failedFollowing process will cause a memleak for copied up znode:dirty_cow_znode zn = copy_znode(c, znode); err = insert_old_idx(c, zbr->lnum, zbr->offs); if (unlikely(err)) return ERR_PTR(err); // No one refers to zn.Fetch a reproducer in [Link].Function copy_znode() is split into 2 parts: resource allocationand znode replacement, insert_old_idx() is split in similar way,so resource cleanup could be done in error handling path withoutcorrupting metadata(mem & disk).It's okay that old index inserting is put behind of add_idx_dirt(),old index is used in layout_leb_in_gaps(), so the two processes donot depend on each other.

Further debugging showedthat igb_enable_sriov()'s call to pci_enable_sriov() is failing, becausedev->is_physfn is 0 on 82580.Prior to commit 50f303496d92 ("igb: Enable SR-IOV after reinit"),igb_enable_sriov() jumped into the "err_out" cleanup branch. After thiscommit it only returned the error code.So the cleanup didn't take place, and the incorrect VF setup in theigb_adapter structure fooled the igb driver into assuming that VFs havebeen set up where no VF actually existed.Fix this problem by cleaning up again if pci_enable_sriov() fails.

CVE-2023-54081 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:xen: speed up grant-table reclaimWhen a grant entry is still in use by the remote domain, Linux must putit on a deferred list. Normally, this list is very short, becausethe PV network and block protocols expect the backend to unmap the grantfirst. However, Qubes OS's GUI protocol is subject to the constraintsof the X Window System, and as such winds up with the frontend unmappingthe window first. As a result, the list can grow very large, resultingin a massive memory leak and eventual VM freeze.To partially solve this problem, make the number of entries that the VMwill attempt to free at each iteration tunable. The default is still10, but it can be overridden via a module parameter.This is Cc: stable because (when combined with appropriate userspacechanges) it fixes a severe performance and stability problem for QubesOS users.

However,immediately after this, the rings are reconfigured by ixgbe_setup_tc.ixgbe_setup_tc calls ixgbe_clear_interrupt_scheme which callsixgbe_free_q_vectors which calls ixgbe_free_q_vector in a loop.ixgbe_free_q_vector decrements ixgbe_xdp_locking_key once per call ifit is non-zero. Commenting out the decrement in ixgbe_free_q_vectorstopped my system from panicing.I suspect to make the original patch work, I would need to load an XDPprogram and then replace it in order to get ixgbe_xdp_locking_key backabove 0 since ixgbe_setup_tc is only called when transitioning betweenXDP and non-XDP ring configurations, while ixgbe_xdp_locking_key isincremented every time ixgbe_xdp_setup is called.Also, ixgbe_setup_tc can be called via ethtool --set-channels, so thisbecomes another path to decrement ixgbe_xdp_locking_key to 0 on systemswith more than 64 CPUs.Since ixgbe_xdp_locking_key only protects the XDP_TX path and is tiedto the number of CPUs present, there is no reason to disable it uponunloading an XDP program. To avoid confusion, I have moved enablingixgbe_xdp_locking_key into ixgbe_sw_init, which is part of the probe path.

Description: In the Linux kernel, the following vulnerability has been resolved:powerpc/iommu: Fix notifiers being shared by PCI and VIO busesfail_iommu_setup() registers the fail_iommu_bus_notifier struct to bothPCI and VIO buses. struct notifier_block is a linked list node, so thiscauses any notifiers later registered to either bus type to also beregistered to the other since they share the same node.This causes issues in (at least) the vgaarb code, which registers anotifier for PCI buses. pci_notify() ends up being called on a viodevice, converted with to_pci_dev() even though it's not a PCI device,and finally makes a bad access in vga_arbiter_add_pci_device() asdiscovered with KASAN: BUG: KASAN: slab-out-of-bounds in vga_arbiter_add_pci_device+0x60/0xe00 Read of size 4 at addr c000000264c26fdc by task swapper/0/1 Call Trace: dump_stack_lvl+0x1bc/0x2b8 (unreliable) print_report+0x3f4/0xc60 kasan_report+0x244/0x698 __asan_load4+0xe8/0x250 vga_arbiter_add_pci_device+0x60/0xe00 pci_notify+0x88/0x444 notifier_call_chain+0x104/0x320 blocking_notifier_call_chain+0xa0/0x140 device_add+0xac8/0x1d30 device_register+0x58/0x80 vio_register_device_node+0x9ac/0xce0 vio_bus_scan_register_devices+0xc4/0x13c __machine_initcall_pseries_vio_device_init+0x94/0xf0 do_one_initcall+0x12c/0xaa8 kernel_init_freeable+0xa48/0xba8 kernel_init+0x64/0x400 ret_from_kernel_thread+0x5c/0x64Fix this by creating separate notifier_block structs for each bus type.[mpe: Add #ifdef to fix CONFIG_IBMVIO=n build]

CVE-2023-54099 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fs: Protect reconfiguration of sb read-write from racing writesThe reconfigure / remount code takes a lot of effort to protectfilesystem's reconfiguration code from racing writes on remountingread-only. However during remounting read-only filesystem to read-writemode userspace writes can start immediately once we clear SB_RDONLYflag. This is inconvenient for example for ext4 because we need to dosome writes to the filesystem (such as preparation of quota files)before we can take userspace writes so we are clearing SB_RDONLY flagbefore we are fully ready to accept userpace writes and syzbot has founda way to exploit this [1]. Also as far as I'm reading the codethe filesystem remount code was protected from racing writes in thelegacy mount path by the mount's MNT_READONLY flag so this is relativelynew problem. It is actually fairly easy to protect remount read-writefrom racing writes using sb->s_readonly_remount flag so let's just dothat instead of having to workaround these races in the filesystem code.[1] https://lore.kernel.org/all/00000000000006a0df05f6667499@google.com/T/

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix incorrect splitting in btrfs_drop_extent_map_rangeIn production we were seeing a variety of WARN_ON()'s in the extent_mapcode, specifically in btrfs_drop_extent_map_range() when we have to calladd_extent_mapping() for our second split.Consider the following extent map layout PINNED [0 16K) [32K, 48K)and then we call btrfs_drop_extent_map_range for [0, 36K), withskip_pinned == true. The initial loop will have start = 0 end = 36K len = 36Kwe will find the [0, 16k) extent, but since we are pinned we will skipit, which has this code start = em_end; if (end != (u64)-1) len = start + len - em_end;em_end here is 16K, so now the values are start = 16K len = 16K + 36K - 16K = 36Klen should instead be 20K. This is a problem when we find the nextextent at [32K, 48K), we need to split this extent to leave [36K, 48k),however the code for the split looks like this split->start = start + len; split->len = em_end - (start + len);In this case we have em_end = 48K split->start = 16K + 36K // this should be 16K + 20K split->len = 48K - (16K + 36K) // this overflows as 16K + 36K is 52Kand now we have an invalid extent_map in the tree that potentiallyoverlaps other entries in the extent map. Even in the non-overlappingcase we will have split->start set improperly, which will cause problemswith any block related calculations.We don't actually need len in this loop, we can simply use end as ourend point, and only adjust start up when we find a pinned extent we needto skip.Adjust the logic to do this, which keeps us from inserting an invalidextent map.We only skip_pinned in the relocation case, so this is relatively rare,except in the case where you are running relocation a lot, which canhappen with auto relocation on.

CVE-2023-54129 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:octeontx2-af: Add validation for lmac typeUpon physical link change, firmware reports to the kernel about thechange along with the details like speed, lmac_type_id, etc.Kernel derives lmac_type based on lmac_type_id received from firmware.In a few scenarios, firmware returns an invalid lmac_type_id, whichis resulting in below kernel panic. This patch adds the missingvalidation of the lmac_type_id field.Internal error: Oops: 96000005 [#1] PREEMPT SMP[ 35.321595] Modules linked in:[ 35.328982] CPU: 0 PID: 31 Comm: kworker/0:1 Not tainted5.4.210-g2e3169d8e1bc-dirty #17[ 35.337014] Hardware name: Marvell CN103XX board (DT)[ 35.344297] Workqueue: events work_for_cpu_fn[ 35.352730] pstate: 40400089 (nZcv daIf +PAN -UAO)[ 35.360267] pc : strncpy+0x10/0x30[ 35.366595] lr : cgx_link_change_handler+0x90/0x180

Description: In the Linux kernel, the following vulnerability has been resolved:hfs/hfsplus: avoid WARN_ON() for sanity check, use proper error handlingCommit 55d1cbbbb29e ("hfs/hfsplus: use WARN_ON for sanity check") fixeda build warning by turning a comment into a WARN_ON(), but it turns outthat syzbot then complains because it can trigger said warning with acorrupted hfs image.The warning actually does warn about a bad situation, but we are muchbetter off just handling it as the error it is. So rather than warnabout us doing bad things, stop doing the bad things and return -EIO.While at it, also fix a memory leak that was introduced by an earlierfix for a similar syzbot warning situation, and add a check for one casethat historically wasn't handled at all (ie neither comment norsubsequent WARN_ON).

The function registers its global DNS resolver cache as current->cred.thread_keyring and passes the query to request_key_net() -> request_key_tag() -> request_key_and_link().* Function request_key_and_link() creates a keyring_search_context object. Its match_data.cmp method gets set via a call to type->match_preparse() (resolves to dns_resolver_match_preparse()) to dns_resolver_cmp().* Function request_key_and_link() continues and invokes search_process_keyrings_rcu() which returns that a given key was not found. The control is then passed to request_key_and_link() -> construct_alloc_key().* Concurrently to that, a second task similarly makes a DNS query for "abcdef." and its result gets inserted into the DNS resolver cache.* Back on the first task, function construct_alloc_key() first runs __key_link_begin() to determine an assoc_array_edit operation to insert a new key. Index keys in the array are compared exactly as-is, using keyring_compare_object(). The operation ---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix issue in verifying allow_ptr_leaksAfter we converted the capabilities of our networking-bpf program fromcap_sys_admin to cap_net_admin+cap_bpf, our networking-bpf programfailed to start. Because it failed the bpf verifier, and the error logis "R3 pointer comparison prohibited".A simple reproducer as follows,SEC("cls-ingress")int ingress(struct __sk_buff *skb){ struct iphdr *iph = (void *)(long)skb->data + sizeof(struct ethhdr); if ((long)(iph + 1) > (long)skb->data_end) return TC_ACT_STOLEN; return TC_ACT_OK;}Per discussion with Yonghong and Alexei [1], comparison of two packetpointers is not a pointer leak. This patch fixes it.Our local kernel is 6.1.y and we expect this fix to be backported to6.1.y, so stable is CCed.[1]. https://lore.kernel.org/bpf/CAADnVQ+Nmspr7Si+pxWn8zkE7hX-7s93ugwC+94aXSy4uQ9vBg@mail.gmail.com/

CVE-2023-54251 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: taprio: Limit TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME to INT_MAX.syzkaller found zero division error [0] in div_s64_rem() called fromget_cycle_time_elapsed(), where sched->cycle_time is the divisor.We have tests in parse_taprio_schedule() so that cycle_time will neverbe 0, and actually cycle_time is not 0 in get_cycle_time_elapsed().The problem is that the types of divisor are different; cycle_time iss64, but the argument of div_s64_rem() is s32.syzkaller fed this input and 0x100000000 is cast to s32 to be 0. @TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME={0xc, 0x8, 0x100000000}We use s64 for cycle_time to cast it to ktime_t, so let's keep it andset max for cycle_time.While at it, we prevent overflow in setup_txtime() and add anothertest in parse_taprio_schedule() to check if cycle_time overflows.Also, we add a new tdc test case for this issue.[0]:divide error: 0000 [#1] PREEMPT SMP KASAN NOPTICPU: 1 PID: 103 Comm: kworker/1:3 Not tainted 6.5.0-rc1-00330-g60cc1f7d0605 #3Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.0-0-gd239552ce722-prebuilt.qemu.org 04/01/2014Workqueue: ipv6_addrconf addrconf_dad_workRIP: 0010:div_s64_rem include/linux/math64.h:42 [inline]RIP: 0010:get_cycle_time_elapsed net/sched/sch_taprio.c:223 [inline]RIP: 0010:find_entry_to_transmit+0x252/0x7e0 net/sched/sch_taprio.c:344Code: 3c 02 00 0f 85 5e 05 00 00 48 8b 4c 24 08 4d 8b bd 40 01 00 00 48 8b 7c 24 48 48 89 c8 4c 29 f8 48 63 f7 48 99 48 89 74 24 70 <48> f7 fe 48 29 d1 48 8d 04 0f 49 89 cc 48 89 44 24 20 49 8d 85 10RSP: 0018:ffffc90000acf260 EFLAGS: 00010206RAX: 177450e0347560cf RBX: 0000000000000000 RCX: 177450e0347560cfRDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000100000000RBP: 0000000000000056 R08: 0000000000000000 R09: ffffed10020a0934R10: ffff8880105049a7 R11: ffff88806cf3a520 R12: ffff888010504800R13: ffff88800c00d800 R14: ffff8880105049a0 R15: 0000000000000000FS: 0000000000000000(0000) GS:ffff88806cf00000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007f0edf84f0e8 CR3: 000000000d73c002 CR4: 0000000000770ee0PKRU: 55555554Call Trace: get_packet_txtime net/sched/sch_taprio.c:508 [inline] taprio_enqueue_one+0x900/0xff0 net/sched/sch_taprio.c:577 taprio_enqueue+0x378/0xae0 net/sched/sch_taprio.c:658 dev_qdisc_enqueue+0x46/0x170 net/core/dev.c:3732 __dev_xmit_skb net/core/dev.c:3821 [inline] __dev_queue_xmit+0x1b2f/0x3000 net/core/dev.c:4169 dev_queue_xmit include/linux/netdevice.h:3088 [inline] neigh_resolve_output net/core/neighbour.c:1552 [inline] neigh_resolve_output+0x4a7/0x780 net/core/neighbour.c:1532 neigh_output include/net/neighbour.h:544 [inline] ip6_finish_output2+0x924/0x17d0 net/ipv6/ip6_output.c:135 __ip6_finish_output+0x620/0xaa0 net/ipv6/ip6_output.c:196 ip6_finish_output net/ipv6/ip6_output.c:207 [inline] NF_HOOK_COND include/linux/netfilter.h:292 [inline] ip6_output+0x206/0x410 net/ipv6/ip6_output.c:228 dst_output include/net/dst.h:458 [inline] NF_HOOK.constprop.0+0xea/0x260 include/linux/netfilter.h:303 ndisc_send_skb+0x872/0xe80 net/ipv6/ndisc.c:508 ndisc_send_ns+0xb5/0x130 net/ipv6/ndisc.c:666 addrconf_dad_work+0xc14/0x13f0 net/ipv6/addrconf.c:4175 process_one_work+0x92c/0x13a0 kernel/workqueue.c:2597 worker_thread+0x60f/0x1240 kernel/workqueue.c:2748 kthread+0x2fe/0x3f0 kernel/kthread.c:389 ret_from_fork+0x2c/0x50 arch/x86/entry/entry_64.S:308 Modules linked in:

This may result in a deadlock andtrigger the following lockdep splat: WARNING: possible circular locking dependency detected 6.5.0-rc7-syzkaller-00004-gf7757129e3de #0 Not tainted ------------------------------------------------------ syz-executor277/5012 is trying to acquire lock: ffff88802df41710 (btrfs-tree-01){++++}-{3:3}, at: __btrfs_tree_read_lock+0x2f/0x220 fs/btrfs/locking.c:136 but task is already holding lock: ffff88802df418e8 (btrfs-tree-00){++++}-{3:3}, at: __btrfs_tree_read_lock+0x2f/0x220 fs/btrfs/locking.c:136 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (btrfs-tree-00){++++}-{3:3}: down_read_nested+0x49/0x2f0 kernel/locking/rwsem.c:1645 __btrfs_tree_read_lock+0x2f/0x220 fs/btrfs/locking.c:136 btrfs_search_slot+0x13a4/0x2f80 fs/btrfs/ctree.c:2302 btrfs_init_root_free_objectid+0x148/0x320 fs/btrfs/disk-io.c:4955 btrfs_init_fs_root fs/btrfs/disk-io.c:1128 [inline] btrfs_get_root_ref+0x5ae/0xae0 fs/btrfs/disk-io.c:1338 btrfs_get_fs_root fs/btrfs/disk-io.c:1390 [inline] open_ctree+0x29c8/0x3030 fs/btrfs/disk-io.c:3494 btrfs_fill_super+0x1c7/0x2f0 fs/btrfs/super.c:1154 btrfs_mount_root+0x7e0/0x910 fs/btrfs/super.c:1519 legacy_get_tree+0xef/0x190 fs/fs_context.c:611 vfs_get_tree+0x8c/0x270 fs/super.c:1519 fc_mount fs/namespace.c:1112 [inline] vfs_kern_mount+0xbc/0x150 fs/namespace.c:1142 btrfs_mount+0x39f/0xb50 fs/btrfs/super.c:1579 legacy_get_tree+0xef/0x190 fs/fs_context.c:611 vfs_get_tree+0x8c/0x270 fs/super.c:1519 do_new_mount+0x28f/0xae0 fs/namespace.c:3335 do_mount fs/namespace.c:3675 [inline] __do_sys_mount fs/namespace.c:3884 [inline] __se_sys_mount+0x2d9/0x3c0 fs/namespace.c:3861 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x41/0xc0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcd -> #0 (btrfs-tree-01){++++}-{3:3}: check_prev_add kernel/locking/lockdep.c:3142 [inline] check_prevs_add kernel/locking/lockdep.c:3261 [inline] validate_chain kernel/locking/lockdep.c:3876 [inline] __lock_acquire+0x39ff/0x7f70 kernel/locking/lockdep.c:5144 lock_acquire+0x1e3/0x520 kernel/locking/lockdep.c:5761 down_read_nested+0x49/0x2f0 kernel/locking/rwsem.c:1645 __btrfs_tree_read_lock+0x2f/0x220 fs/btrfs/locking.c:136 btrfs_tree_read_lock fs/btrfs/locking.c:142 [inline] btrfs_read_lock_root_node+0x292/0x3c0 fs/btrfs/locking.c:281 btrfs_search_slot_get_root fs/btrfs/ctree.c:1832 [inline] btrfs_search_slot+0x4ff/0x2f80 fs/btrfs/ctree.c:2154 btrfs_lookup_inode+0xdc/0x480 fs/btrfs/inode-item.c:412 btrfs_read_locked_inode fs/btrfs/inode.c:3892 [inline] btrfs_iget_path+0x2d9/0x1520 fs/btrfs/inode.c:5716 btrfs_search_path_in_tree_user fs/btrfs/ioctl.c:1961 [inline] btrfs_ioctl_ino_lookup_user+0x77a/0xf50 fs/btrfs/ioctl.c:2105 btrfs_ioctl+0xb0b/0xd40 fs/btrfs/ioctl.c:4683 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:870 [inline] __se_sys_ioctl+0xf8/0x170 fs/ioctl.c:856 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x41/0xc0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcd other info ---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:media: av7110: prevent underflow in write_ts_to_decoder()The buf[4] value comes from the user via ts_play(). It is a value inthe u8 range. The final length we pass to av7110_ipack_instant_repack()is "len - (buf[4] + 1) - 4" so add a check to ensure that the length isnot negative. It's not clear that passing a negative len value doesanything bad necessarily, but it's not best practice.With the new bounds checking the "if (!len)" condition is no longerpossible or required so remove that.

Description: In the Linux kernel, the following vulnerability has been resolved:fs/xattr: missing fdput() in fremovexattr error pathIn the Linux kernel, the fremovexattr() syscall calls fdget() to acquire afile reference but returns early without calling fdput() whenstrncpy_from_user() fails on the name argument. In multi-threaded processeswhere fdget() takes the slow path, this permanently leaks onefile reference per call, pinning the struct file and associated kernelobjects in memory. An unprivileged local user can exploit this to causekernel memory exhaustion. The issue was inadvertently fixed by commita71874379ec8 ("xattr: switch to CLASS(fd)").

Assumed that the connection has been registered in alink group by smc_conn_create() but the rmb_desc has not yet beeninitialized by smc_buf_create(), thus causing the illegal access toconn->rmb_desc. So fix it by checking before dump.

CVE-2024-26627 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: core: Move scsi_host_busy() out of host lock for waking up EH handlerInside scsi_eh_wakeup(), scsi_host_busy() is called & checked with hostlock every time for deciding if error handler kthread needs to be waken up.This can be too heavy in case of recovery, such as: - N hardware queues - queue depth is M for each hardware queue - each scsi_host_busy() iterates over (N * M) tag/requestsIf recovery is triggered in case that all requests are in-flight, eachscsi_eh_wakeup() is strictly serialized, when scsi_eh_wakeup() is calledfor the last in-flight request, scsi_host_busy() has been run for (N * M -1) times, and request has been iterated for (N*M - 1) * (N * M) times.If both N and M are big enough, hard lockup can be triggered on acquiringhost lock, and it is observed on mpi3mr(128 hw queues, queue depth 8169).Fix the issue by calling scsi_host_busy() outside the host lock. We don'tneed the host lock for getting busy count because host the lock nevercovers that.[mkp: Drop unnecessary 'busy' variables pointed out by Bart]

CVE-2024-26659 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:xhci: handle isoc Babble and Buffer Overrun events properlyxHCI 4.9 explicitly forbids assuming that the xHC has released itsownership of a multi-TRB TD when it reports an error on one of theearly TRBs. Yet the driver makes such assumption and releases the TD,allowing the remaining TRBs to be freed or overwritten by new TDs.The xHC should also report completion of the final TRB due to its IOCflag being set by us, regardless of prior errors. This event cannotbe recognized if the TD has already been freed earlier, resulting in"Transfer event TRB DMA ptr not part of current TD" error message.Fix this by reusing the logic for processing isoc Transaction Errors.This also handles hosts which fail to report the final completion.Fix transfer length reporting on Babble errors. They may be caused bydevice malfunction, no guarantee that the buffer has been filled.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amd/display: Implement bounds check for stream encoder creation in DCN301'stream_enc_regs' array is an array of dcn10_stream_enc_registersstructures. The array is initialized with four elements, correspondingto the four calls to stream_enc_regs() in the array initializer. Thismeans that valid indices for this array are 0, 1, 2, and 3.The error message 'stream_enc_regs' 4 <= 5 below, is indicating thatthere is an attempt to access this array with an index of 5, which isout of bounds. This could lead to undefined behaviorHere, eng_id is used as an index to access the stream_enc_regs array. Ifeng_id is 5, this would result in an out-of-bounds access on thestream_enc_regs array.Thus fixing Buffer overflow error in dcn301_stream_encoder_createreported by Smatch:drivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn301/dcn301_resource.c:1011 dcn301_stream_encoder_create() error: buffer overflow 'stream_enc_regs' 4 <= 5

CVE-2024-26669 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: flower: Fix chain template offloadWhen a qdisc is deleted from a net device the stack instructs theunderlying driver to remove its flow offload callback from theassociated filter block using the 'FLOW_BLOCK_UNBIND' command. The stackthen continues to replay the removal of the filters in the block forthis driver by iterating over the chains in the block and invoking the'reoffload' operation of the classifier being used. In turn, theclassifier in its 'reoffload' operation prepares and emits a'FLOW_CLS_DESTROY' command for each filter.However, the stack does not do the same for chain templates and theunderlying driver never receives a 'FLOW_CLS_TMPLT_DESTROY' command whena qdisc is deleted. This results in a memory leak [1] which can bereproduced using [2].Fix by introducing a 'tmplt_reoffload' operation and have the stackinvoke it with the appropriate arguments as part of the replay.Implement the operation in the sole classifier that supports chaintemplates (flower) by emitting the 'FLOW_CLS_TMPLT_{CREATE,DESTROY}'command based on whether a flow offload callback is being bound to afilter block or being unbound from one.As far as I can tell, the issue happens since cited commit whichreordered tcf_block_offload_unbind() before tcf_block_flush_all_chains()in __tcf_block_put(). The order cannot be reversed as the filter blockis expected to be freed after flushing all the chains.[1]unreferenced object 0xffff888107e28800 (size 2048): comm "tc", pid 1079, jiffies 4294958525 (age 3074.287s) hex dump (first 32 bytes): b1 a6 7c 11 81 88 ff ff e0 5b b3 10 81 88 ff ff ..|......[...... 01 00 00 00 00 00 00 00 e0 aa b0 84 ff ff ff ff ................ backtrace: [] __kmem_cache_alloc_node+0x1e8/0x320 [] __kmalloc+0x4e/0x90 [] mlxsw_sp_acl_ruleset_get+0x34d/0x7a0 [] mlxsw_sp_flower_tmplt_create+0x145/0x180 [] mlxsw_sp_flow_block_cb+0x1ea/0x280 [] tc_setup_cb_call+0x183/0x340 [] fl_tmplt_create+0x3da/0x4c0 [] tc_ctl_chain+0xa15/0x1170 [] rtnetlink_rcv_msg+0x3cc/0xed0 [] netlink_rcv_skb+0x170/0x440 [] netlink_unicast+0x540/0x820 [] netlink_sendmsg+0x8d8/0xda0 [] ____sys_sendmsg+0x30f/0xa80 [] ___sys_sendmsg+0x13a/0x1e0 [] __sys_sendmsg+0x11c/0x1f0 [] do_syscall_64+0x40/0xe0unreferenced object 0xffff88816d2c0400 (size 1024): comm "tc", pid 1079, jiffies 4294958525 (age 3074.287s) hex dump (first 32 bytes): 40 00 00 00 00 00 00 00 57 f6 38 be 00 00 00 00 @.......W.8..... 10 04 2c 6d 81 88 ff ff 10 04 2c 6d 81 88 ff ff ..,m......,m.... backtrace: [] __kmem_cache_alloc_node+0x1e8/0x320 [] __kmalloc_node+0x51/0x90 [] kvmalloc_node+0xa6/0x1f0 [] bucket_table_alloc.isra.0+0x83/0x460 [] rhashtable_init+0x43b/0x7c0 [] mlxsw_sp_acl_ruleset_get+0x428/0x7a0 [] mlxsw_sp_flower_tmplt_create+0x145/0x180 [] mlxsw_sp_flow_block_cb+0x1ea/0x280 [] tc_setup_cb_call+0x183/0x340 [] fl_tmplt_create+0x3da/0x4c0 [] tc_ctl_chain+0xa15/0x1170 [] rtnetlink_rcv_msg+0x3cc/0xed0 [] netlink_rcv_skb+0x170/0x440 [] netlink_unicast+0x540/0x820 [] netlink_sendmsg+0x8d8/0xda0 [] ____sys_sendmsg+0x30f/0xa80[2] # tc qdisc add dev swp1 clsact # tc chain add dev swp1 ingress proto ip chain 1 flower dst_ip 0.0.0.0/32 # tc qdisc del dev---truncated---

CVE-2024-26685 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: fix potential bug in end_buffer_async_writeAccording to a syzbot report, end_buffer_async_write(), which handles thecompletion of block device writes, may detect abnormal condition of thebuffer async_write flag and cause a BUG_ON failure when using nilfs2.Nilfs2 itself does not use end_buffer_async_write(). But, the async_writeflag is now used as a marker by commit 7f42ec394156 ("nilfs2: fix issuewith race condition of competition between segments for dirty blocks") asa means of resolving double list insertion of dirty blocks innilfs_lookup_dirty_data_buffers() and nilfs_lookup_node_buffers() and theresulting crash.This modification is safe as long as it is used for file data and b-treenode blocks where the page caches are independent. However, it wasirrelevant and redundant to also introduce async_write for segment summaryand super root blocks that share buffers with the backing device. Thisled to the possibility that the BUG_ON check in end_buffer_async_writewould fail as described above, if independent writebacks of the backingdevice occurred in parallel.The use of async_write for segment summary buffers has already beenremoved in a previous change.Fix this issue by removing the manipulation of the async_write flag forthe remaining super root block buffer.

CVE-2024-26696 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: fix hang in nilfs_lookup_dirty_data_buffers()Syzbot reported a hang issue in migrate_pages_batch() called by mbind()and nilfs_lookup_dirty_data_buffers() called in the log writer of nilfs2.While migrate_pages_batch() locks a folio and waits for the writeback tocomplete, the log writer thread that should bring the writeback tocompletion picks up the folio being written back innilfs_lookup_dirty_data_buffers() that it calls for subsequent logcreation and was trying to lock the folio. Thus causing a deadlock.In the first place, it is unexpected that folios/pages in the middle ofwriteback will be updated and become dirty. Nilfs2 adds a checksum toverify the validity of the log being written and uses it for recovery atmount, so data changes during writeback are suppressed. Since this isbroken, an unclean shutdown could potentially cause recovery to fail.Investigation revealed that the root cause is that the wait for writebackcompletion in nilfs_page_mkwrite() is conditional, and if the backingdevice does not require stable writes, data may be modified withoutwaiting.Fix these issues by making nilfs_page_mkwrite() wait for writeback tofinish regardless of the stable write requirement of the backing device.

Description: In the Linux kernel, the following vulnerability has been resolved:hv_netvsc: Fix race condition between netvsc_probe and netvsc_removeIn commit ac5047671758 ("hv_netvsc: Disable NAPI before closing theVMBus channel"), napi_disable was getting called for all channels,including all subchannels without confirming if they are enabled or not.This caused hv_netvsc getting hung at napi_disable, when netvsc_probe()has finished running but nvdev->subchan_work has not started yet.netvsc_subchan_work() -> rndis_set_subchannel() has not created thesub-channels and because of that netvsc_sc_open() is not running.netvsc_remove() calls cancel_work_sync(&nvdev->subchan_work), for whichnetvsc_subchan_work did not run.netif_napi_add() sets the bit NAPI_STATE_SCHED because it ensures NAPIcannot be scheduled. Then netvsc_sc_open() -> napi_enable will clear theNAPIF_STATE_SCHED bit, so it can be scheduled. napi_disable() does theopposite.Now during netvsc_device_remove(), when napi_disable is called for thosesubchannels, napi_disable gets stuck on infinite msleep.This fix addresses this problem by ensuring that napi_disable() is notgetting called for non-enabled NAPI struct.But netif_napi_del() is still necessary for these non-enabled NAPI structfor cleanup purpose.Call trace:[ 654.559417] task:modprobe state:D stack: 0 pid: 2321 ppid: 1091 flags:0x00004002[ 654.568030] Call Trace:[ 654.571221] [ 654.573790] __schedule+0x2d6/0x960[ 654.577733] schedule+0x69/0xf0[ 654.581214] schedule_timeout+0x87/0x140[ 654.585463] ? __bpf_trace_tick_stop+0x20/0x20[ 654.590291] msleep+0x2d/0x40[ 654.593625] napi_disable+0x2b/0x80[ 654.597437] netvsc_device_remove+0x8a/0x1f0 [hv_netvsc][ 654.603935] rndis_filter_device_remove+0x194/0x1c0 [hv_netvsc][ 654.611101] ? do_wait_intr+0xb0/0xb0[ 654.615753] netvsc_remove+0x7c/0x120 [hv_netvsc][ 654.621675] vmbus_remove+0x27/0x40 [hv_vmbus]

Description: In the Linux kernel, the following vulnerability has been resolved:dm-crypt, dm-verity: disable taskletsTasklets have an inherent problem with memory corruption. The functiontasklet_action_common calls tasklet_trylock, then it calls the taskletcallback and then it calls tasklet_unlock. If the tasklet callback freesthe structure that contains the tasklet or if it calls some code that mayfree it, tasklet_unlock will write into free memory.The commits 8e14f610159d and d9a02e016aaf try to fix it for dm-crypt, butit is not a sufficient fix and the data corruption can still happen [1].There is no fix for dm-verity and dm-verity will write into free memorywith every tasklet-processed bio.There will be atomic workqueues implemented in the kernel 6.9 [2]. Theywill have better interface and they will not suffer from the memorycorruption problem.But we need something that stops the memory corruption now and that can bebackported to the stable kernels. So, I'm proposing this commit thatdisables tasklets in both dm-crypt and dm-verity. This commit doesn'tremove the tasklet support, because the tasklet code will be reused whenatomic workqueues will be implemented.[1] https://lore.kernel.org/all/d390d7ee-f142-44d3-822a-87949e14608b@suse.de/T/[2] https://lore.kernel.org/lkml/20240130091300.2968534-1-tj@kernel.org/

CVE-2024-26798 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fbcon: always restore the old font data in fbcon_do_set_font()Commit a5a923038d70 (fbdev: fbcon: Properly revert changes whenvc_resize() failed) started restoring old font data upon failure (ofvc_resize()). But it performs so only for user fonts. It means that the"system"/internal fonts are not restored at all. So in result, the veryfirst call to fbcon_do_set_font() performs no restore at all uponfailing vc_resize().This can be reproduced by Syzkaller to crash the system on the nextinvocation of font_get(). It's rather hard to hit the allocation failurein vc_resize() on the first font_set(), but not impossible. Esp. iffault injection is used to aid the execution/failure. It wasdemonstrated by Sirius: BUG: unable to handle page fault for address: fffffffffffffff8 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD cb7b067 P4D cb7b067 PUD cb7d067 PMD 0 Oops: 0000 [#1] PREEMPT SMP KASAN CPU: 1 PID: 8007 Comm: poc Not tainted 6.7.0-g9d1694dc91ce #20 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 RIP: 0010:fbcon_get_font+0x229/0x800 drivers/video/fbdev/core/fbcon.c:2286 Call Trace: con_font_get drivers/tty/vt/vt.c:4558 [inline] con_font_op+0x1fc/0xf20 drivers/tty/vt/vt.c:4673 vt_k_ioctl drivers/tty/vt/vt_ioctl.c:474 [inline] vt_ioctl+0x632/0x2ec0 drivers/tty/vt/vt_ioctl.c:752 tty_ioctl+0x6f8/0x1570 drivers/tty/tty_io.c:2803 vfs_ioctl fs/ioctl.c:51 [inline] ...So restore the font data in any case, not only for user fonts.

CVE-2024-26802 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:stmmac: Clear variable when destroying workqueueCurrently when suspending driver and stopping workqueue it is checked whetherworkqueue is not NULL and if so, it is destroyed.Function destroy_workqueue() does drain queue and does clear variable, butit does not set workqueue variable to NULL. This can cause kernel/modulepanic if code attempts to clear workqueue that was not initialized.This scenario is possible when resuming suspended driver in stmmac_resume(),because there is no handling for failed stmmac_hw_setup(),which can fail and return if DMA engine has failed to initialize,and workqueue is initialized after DMA engine.Should DMA engine fail to initialize, resume will proceed normally,but interface won't work and TX queue will eventually timeout,causing 'Reset adapter' error.This then does destroy workqueue during reset process.And since workqueue is initialized after DMA engine and can be skipped,it will cause kernel/module panic.To secure against this possible crash, set workqueue variable to NULL whendestroying workqueue.Log/backtrace from crash goes as follows:[88.031977]------------[ cut here ]------------[88.031985]NETDEV WATCHDOG: eth0 (sxgmac): transmit queue 1 timed out[88.032017]WARNING: CPU: 0 PID: 0 at net/sched/sch_generic.c:477 dev_watchdog+0x390/0x398 [88.032251]---[ end trace e70de432e4d5c2c0 ]---[88.032282]sxgmac 16d88000.ethernet eth0: Reset adapter.[88.036359]------------[ cut here ]------------[88.036519]Call trace:[88.036523] flush_workqueue+0x3e4/0x430[88.036528] drain_workqueue+0xc4/0x160[88.036533] destroy_workqueue+0x40/0x270[88.036537] stmmac_fpe_stop_wq+0x4c/0x70[88.036541] stmmac_release+0x278/0x280[88.036546] __dev_close_many+0xcc/0x158[88.036551] dev_close_many+0xbc/0x190[88.036555] dev_close.part.0+0x70/0xc0[88.036560] dev_close+0x24/0x30[88.036564] stmmac_service_task+0x110/0x140[88.036569] process_one_work+0x1d8/0x4a0[88.036573] worker_thread+0x54/0x408[88.036578] kthread+0x164/0x170[88.036583] ret_from_fork+0x10/0x20[88.036588]---[ end trace e70de432e4d5c2c1 ]---[88.036597]Unable to handle kernel NULL pointer dereference at virtual address 0000000000000004

IOW, we skb->data gets "adjusted" by a huge value.The negative value is returned because skb->head and skb->data distance ismore than 64k and skb->network_header (u16) has wrapped around.The bug is in the ip_tunnel infrastructure, which can causedev->needed_headroom to increment ad infinitum.The syzkaller reproducer consists of packets getting routed via a gretunnel, and route of gre encapsulated packets pointing at another (ipip)tunnel. The ipip encapsulation finds gre0 as next output device.This results in the following pattern:1). First packet is to be sent out via gre0.Route lookup found an output device, ipip0.2).ip_tunnel_xmit for gre0 bumps gre0->needed_headroom based on the futureoutput device, rt.dev->needed_headroom (ipip0).3).ip output / start_xmit moves skb on to ipip0. which runs the samecode path again (xmit recursion).4).Routing step for the post-gre0-encap packet finds gre0 as output deviceto use for ipip0 encapsulated packet.tunl0->needed_headroom is then incremented based on the (already bumped)gre0 device headroom.This repeats for every future packet:gre0->needed_headroom gets inflated because previous packets' ipip0 stepincremented rt->dev (gre0) headroom, and ipip0 incremented because gre0needed_headroom was increased.For each subsequent packet, gre/ipip0->needed_headroom grows untilpost-expand-head reallocations result in a skb->head/data distance ofmore than 64k.Once that happens, skb->network_header (u16) wraps around whenpskb_expand_head tries to make sure that skb_network_offset() is unchangedafter the headroom expansion/reallocation.After this skb_network_offset(skb) returns a different (and negative)result post headroom expansion.The next trip to neigh layer (or anything else that would __skb_pull thenetwork header) makes skb->data point to a memory location outsideskb->head area.v2: Cap the needed_headroom update to an arbitarily chosen upperlimit toprevent perpetual increase instead of dropping the headroom incrementcompletely.

Description: In the Linux kernel, the following vulnerability has been resolved:netlink: Fix kernel-infoleak-after-free in __skb_datagram_itersyzbot reported the following uninit-value access issue [1]:netlink_to_full_skb() creates a new `skb` and puts the `skb->data`passed as a 1st arg of netlink_to_full_skb() onto new `skb`. The datasize is specified as `len` and passed to skb_put_data(). This `len`is based on `skb->end` that is not data offset but buffer offset. The`skb->end` contains data and tailroom. Since the tailroom is notinitialized when the new `skb` created, KMSAN detects uninitializedmemory area when copying the data.This patch resolved this issue by correct the len from `skb->end` to`skb->len`, which is the actual data offset.BUG: KMSAN: kernel-infoleak-after-free in instrument_copy_to_user include/linux/instrumented.h:114 [inline]BUG: KMSAN: kernel-infoleak-after-free in copy_to_user_iter lib/iov_iter.c:24 [inline]BUG: KMSAN: kernel-infoleak-after-free in iterate_ubuf include/linux/iov_iter.h:29 [inline]BUG: KMSAN: kernel-infoleak-after-free in iterate_and_advance2 include/linux/iov_iter.h:245 [inline]BUG: KMSAN: kernel-infoleak-after-free in iterate_and_advance include/linux/iov_iter.h:271 [inline]BUG: KMSAN: kernel-infoleak-after-free in _copy_to_iter+0x364/0x2520 lib/iov_iter.c:186 instrument_copy_to_user include/linux/instrumented.h:114 [inline] copy_to_user_iter lib/iov_iter.c:24 [inline] iterate_ubuf include/linux/iov_iter.h:29 [inline] iterate_and_advance2 include/linux/iov_iter.h:245 [inline] iterate_and_advance include/linux/iov_iter.h:271 [inline] _copy_to_iter+0x364/0x2520 lib/iov_iter.c:186 copy_to_iter include/linux/uio.h:197 [inline] simple_copy_to_iter+0x68/0xa0 net/core/datagram.c:532 __skb_datagram_iter+0x123/0xdc0 net/core/datagram.c:420 skb_copy_datagram_iter+0x5c/0x200 net/core/datagram.c:546 skb_copy_datagram_msg include/linux/skbuff.h:3960 [inline] packet_recvmsg+0xd9c/0x2000 net/packet/af_packet.c:3482 sock_recvmsg_nosec net/socket.c:1044 [inline] sock_recvmsg net/socket.c:1066 [inline] sock_read_iter+0x467/0x580 net/socket.c:1136 call_read_iter include/linux/fs.h:2014 [inline] new_sync_read fs/read_write.c:389 [inline] vfs_read+0x8f6/0xe00 fs/read_write.c:470 ksys_read+0x20f/0x4c0 fs/read_write.c:613 __do_sys_read fs/read_write.c:623 [inline] __se_sys_read fs/read_write.c:621 [inline] __x64_sys_read+0x93/0xd0 fs/read_write.c:621 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0x44/0x110 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x63/0x6bUninit was stored to memory at: skb_put_data include/linux/skbuff.h:2622 [inline] netlink_to_full_skb net/netlink/af_netlink.c:181 [inline] __netlink_deliver_tap_skb net/netlink/af_netlink.c:298 [inline] __netlink_deliver_tap+0x5be/0xc90 net/netlink/af_netlink.c:325 netlink_deliver_tap net/netlink/af_netlink.c:338 [inline] netlink_deliver_tap_kernel net/netlink/af_netlink.c:347 [inline] netlink_unicast_kernel net/netlink/af_netlink.c:1341 [inline] netlink_unicast+0x10f1/0x1250 net/netlink/af_netlink.c:1368 netlink_sendmsg+0x1238/0x13d0 net/netlink/af_netlink.c:1910 sock_sendmsg_nosec net/socket.c:730 [inline] __sock_sendmsg net/socket.c:745 [inline] ____sys_sendmsg+0x9c2/0xd60 net/socket.c:2584 ___sys_sendmsg+0x28d/0x3c0 net/socket.c:2638 __sys_sendmsg net/socket.c:2667 [inline] __do_sys_sendmsg net/socket.c:2676 [inline] __se_sys_sendmsg net/socket.c:2674 [inline] __x64_sys_sendmsg+0x307/0x490 net/socket.c:2674 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0x44/0x110 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x63/0x6bUninit was created at: free_pages_prepare mm/page_alloc.c:1087 [inline] free_unref_page_prepare+0xb0/0xa40 mm/page_alloc.c:2347 free_unref_page_list+0xeb/0x1100 mm/page_alloc.c:2533 release_pages+0x23d3/0x2410 mm/swap.c:1042 free_pages_and_swap_cache+0xd9/0xf0 mm/swap_state.c:316 tlb_batch_pages---truncated---

CVE-2024-26807 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:Both cadence-quadspi ->runtime_suspend() and ->runtime_resume()implementations start with: struct cqspi_st *cqspi = dev_get_drvdata(dev); struct spi_controller *host = dev_get_drvdata(dev);This obviously cannot be correct, unless "struct cqspi_st" is thefirst member of " struct spi_controller", or the other way around, butit is not the case. "struct spi_controller" is allocated bydevm_spi_alloc_host(), which allocates an extra amount of memory forprivate data, used to store "struct cqspi_st".The ->probe() function of the cadence-quadspi driver then sets thedevice drvdata to store the address of the "struct cqspi_st"structure. Therefore: struct cqspi_st *cqspi = dev_get_drvdata(dev);is correct, but: struct spi_controller *host = dev_get_drvdata(dev);is not, as it makes "host" point not to a "struct spi_controller" butto the same "struct cqspi_st" structure as above.This obviously leads to bad things (memory corruption, kernel crashes)directly during ->probe(), as ->probe() enables the device using PMruntime, leading the ->runtime_resume() hook being called, which inturns calls spi_controller_resume() with the wrong pointer.This has at least been reported [0] to cause a kernel crash, but theexact behavior will depend on the memory contents.[0] https://lore.kernel.org/all/20240226121803.5a7r5wkpbbowcxgx@dhruva/This issue potentially affects all platforms that are currently usingthe cadence-quadspi driver.

Description: In the Linux kernel, the following vulnerability has been resolved:nfc: nci: free rx_data_reassembly skb on NCI device cleanuprx_data_reassembly skb is stored during NCI data exchange for processingfragmented packets. It is dropped only when the last fragment is processedor when an NTF packet with NCI_OP_RF_DEACTIVATE_NTF opcode is received.However, the NCI device may be deallocated before that which leads to skbleak.As by design the rx_data_reassembly skb is bound to the NCI device andnothing prevents the device to be freed before the skb is processed insome way and cleaned, free it on the NCI device cleanup.Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Description: In the Linux kernel, the following vulnerability has been resolved:mm: zswap: fix missing folio cleanup in writeback race pathIn zswap_writeback_entry(), after we get a folio from__read_swap_cache_async(), we grab the tree lock again to check that theswap entry was not invalidated and recycled. If it was, we delete thefolio we just added to the swap cache and exit.However, __read_swap_cache_async() returns the folio locked when it isnewly allocated, which is always true for this path, and the folio isref'd. Make sure to unlock and put the folio before returning.This was discovered by code inspection, probably because this path handlesa race condition that should not happen often, and the bug would not crashthe system, it will only strand the folio indefinitely.

CVE-2024-26853 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:igc: avoid returning frame twice in XDP_REDIRECTWhen a frame can not be transmitted in XDP_REDIRECT(e.g. due to a full queue), it is necessary to freeit by calling xdp_return_frame_rx_napi.However, this is the responsibility of the caller ofthe ndo_xdp_xmit (see for example bq_xmit_all inkernel/bpf/devmap.c) and thus calling it insideigc_xdp_xmit (which is the ndo_xdp_xmit of the igcdriver) as well will lead to memory corruption.In fact, bq_xmit_all expects that it can return allframes after the last successfully transmitted one.Therefore, break for the first not transmitted frame,but do not call xdp_return_frame_rx_napi in igc_xdp_xmit.This is equally implemented in other Intel driverssuch as the igb.There are two alternatives to this that were rejected:1. Return num_frames as all the frames would have been transmitted and release them inside igc_xdp_xmit. While it might work technically, it is not what the return value is meant to represent (i.e. the number of SUCCESSFULLY transmitted packets).2. Rework kernel/bpf/devmap.c and all drivers to support non-consecutively dropped packets. Besides being complex, it likely has a negative performance impact without a significant gain since it is anyway unlikely that the next frame can be transmitted if the previous one was dropped.The memory corruption can be reproduced withthe following script which leads to a kernel panicafter a few seconds. It basically generates moretraffic than a i225 NIC can transmit and pushes itvia XDP_REDIRECT from a virtual interface to thephysical interface where frames get dropped. #!/bin/bash INTERFACE=enp4s0 INTERFACE_IDX=`cat /sys/class/net/$INTERFACE/ifindex` sudo ip link add dev veth1 type veth peer name veth2 sudo ip link set up $INTERFACE sudo ip link set up veth1 sudo ip link set up veth2 cat << EOF > redirect.bpf.c SEC("prog") int redirect(struct xdp_md *ctx) { return bpf_redirect($INTERFACE_IDX, 0); } char _license[] SEC("license") = "GPL"; EOF clang -O2 -g -Wall -target bpf -c redirect.bpf.c -o redirect.bpf.o sudo ip link set veth2 xdp obj redirect.bpf.o cat << EOF > pass.bpf.c SEC("prog") int pass(struct xdp_md *ctx) { return XDP_PASS; } char _license[] SEC("license") = "GPL"; EOF clang -O2 -g -Wall -target bpf -c pass.bpf.c -o pass.bpf.o sudo ip link set $INTERFACE xdp obj pass.bpf.o cat << EOF > trafgen.cfg { /* Ethernet Header */ 0xe8, 0x6a, 0x64, 0x41, 0xbf, 0x46, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, const16(ETH_P_IP), /* IPv4 Header */ 0b01000101, 0, # IPv4 version, IHL, TOS const16(1028), # IPv4 total length (UDP length + 20 bytes (IP header)) const16(2), # IPv4 ident 0b01000000, 0, # IPv4 flags, fragmentation off 64, # IPv4 TTL 17, # Protocol UDP csumip(14, 33), # IPv4 checksum /* UDP Header */ 10, 0, 1, 1, # IP Src - adapt as needed 10, 0, 1, 2, # IP Dest - adapt as needed const16(6666), # UDP Src Port const16(6666), # UDP Dest Port const16(1008), # UDP length (UDP header 8 bytes + payload length) csumudp(14, 34), # UDP checksum /* Payload */ fill('W', 1000), } EOF sudo trafgen -i trafgen.cfg -b3000MB -o veth1 --cpp

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/srpt: Do not register event handler until srpt device is fully setupUpon rare occasions, KASAN reports a use-after-free Writein srpt_refresh_port().This seems to be because an event handler is registered before thesrpt device is fully setup and a race condition upon error may leave apartially setup event handler in place.Instead, only register the event handler after srpt device initializationis complete.

CVE-2024-26883 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix stackmap overflow check on 32-bit archesThe stackmap code relies on roundup_pow_of_two() to compute the numberof hash buckets, and contains an overflow check by checking if theresulting value is 0. However, on 32-bit arches, the roundup code itselfcan overflow by doing a 32-bit left-shift of an unsigned long value,which is undefined behaviour, so it is not guaranteed to truncateneatly. This was triggered by syzbot on the DEVMAP_HASH type, whichcontains the same check, copied from the hashtab code.The commit in the fixes tag actually attempted to fix this, but the fixdid not account for the UB, so the fix only works on CPUs where anoverflow does result in a neat truncation to zero, which is notguaranteed. Checking the value before rounding does not have thisproblem.

CVE-2024-26885 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix DEVMAP_HASH overflow check on 32-bit archesThe devmap code allocates a number hash buckets equal to the next powerof two of the max_entries value provided when creating the map. Whenrounding up to the next power of two, the 32-bit variable storing thenumber of buckets can overflow, and the code checks for overflow bychecking if the truncated 32-bit value is equal to 0. However, on 32-bitarches the rounding up itself can overflow mid-way through, because itends up doing a left-shift of 32 bits on an unsigned long value. If thesize of an unsigned long is four bytes, this is undefined behaviour, sothere is no guarantee that we'll end up with a nice and tidy 0-value atthe end.Syzbot managed to turn this into a crash on arm32 by creating aDEVMAP_HASH with max_entries > 0x80000000 and then trying to update it.Fix this by moving the overflow check to before the rounding upoperation.

Description: In the Linux kernel, the following vulnerability has been resolved:USB: core: Fix deadlock in usb_deauthorize_interface()Among the attribute file callback routines indrivers/usb/core/sysfs.c, the interface_authorized_store() function isthe only one which acquires a device lock on an ancestor device: Itcalls usb_deauthorize_interface(), which locks the interface's parentUSB device.The will lead to deadlock if another process already owns that lockand tries to remove the interface, whether through a configurationchange or because the device has been disconnected. As part of theremoval procedure, device_del() waits for all ongoing sysfs attributecallbacks to complete. But usb_deauthorize_interface() can't completeuntil the device lock has been released, and the lock won't bereleased until the removal has finished.The mechanism provided by sysfs to prevent this kind of deadlock isto use the sysfs_break_active_protection() function, which tells sysfsnot to wait for the attribute callback.Reported-and-tested by: Yue Sun Reported by: xingwei lee

Description: In the Linux kernel, the following vulnerability has been resolved:wireguard: netlink: access device through ctx instead of peerThe previous commit fixed a bug that led to a NULL peer->device beingdereferenced. It's actually easier and faster performance-wise toinstead get the device from ctx->wg. This semantically makes more sensetoo, since ctx->wg->peer_allowedips.seq is compared withctx->allowedips_seq, basing them both in ctx. This also acts as adefence in depth provision against freed peers.

CVE-2024-26960 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm: swap: fix race between free_swap_and_cache() and swapoff()There was previously a theoretical window where swapoff() could run andteardown a swap_info_struct while a call to free_swap_and_cache() wasrunning in another thread. This could cause, amongst other badpossibilities, swap_page_trans_huge_swapped() (called byfree_swap_and_cache()) to access the freed memory for swap_map.This is a theoretical problem and I haven't been able to provoke it from atest case. But there has been agreement based on code review that this ispossible (see link below).Fix it by using get_swap_device()/put_swap_device(), which will stallswapoff(). There was an extra check in _swap_info_get() to confirm thatthe swap entry was not free. This isn't present in get_swap_device()because it doesn't make sense in general due to the race between gettingthe reference and swapoff. So I've added an equivalent check directly infree_swap_and_cache().Details of how to provoke one possible issue (thanks to David Hildenbrandfor deriving this):--8<-----__swap_entry_free() might be the last user and result in"count == SWAP_HAS_CACHE".swapoff->try_to_unuse() will stop as soon as soon as si->inuse_pages==0.So the question is: could someone reclaim the folio and turnsi->inuse_pages==0, before we completed swap_page_trans_huge_swapped().Imagine the following: 2 MiB folio in the swapcache. Only 2 subpages arestill references by swap entries.Process 1 still references subpage 0 via swap entry.Process 2 still references subpage 1 via swap entry.Process 1 quits. Calls free_swap_and_cache().-> count == SWAP_HAS_CACHE[then, preempted in the hypervisor etc.]Process 2 quits. Calls free_swap_and_cache().-> count == SWAP_HAS_CACHEProcess 2 goes ahead, passes swap_page_trans_huge_swapped(), and calls__try_to_reclaim_swap().__try_to_reclaim_swap()->folio_free_swap()->delete_from_swap_cache()->put_swap_folio()->free_swap_slot()->swapcache_free_entries()->swap_entry_free()->swap_range_free()->...WRITE_ONCE(si->inuse_pages, si->inuse_pages - nr_entries);What stops swapoff to succeed after process 2 reclaimed the swap cachebut before process1 finished its call to swap_page_trans_huge_swapped()?--8<-----

Thispatch on the one hand make sure raid_message() can't changesync_thread() through raid_message() after presuspend(), on the otherhand detect the above 3 cases before wait for IO do be done indm_suspend(), and let dm-raid requeue those IO.

CVE-2024-26982 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:Squashfs: check the inode number is not the invalid value of zeroSyskiller has produced an out of bounds access in fill_meta_index().That out of bounds access is ultimately caused because the inodehas an inode number with the invalid value of zero, which was not checked.The reason this causes the out of bounds access is due to followingsequence of events:1. Fill_meta_index() is called to allocate (via empty_meta_index()) and fill a metadata index. It however suffers a data read error and aborts, invalidating the newly returned empty metadata index. It does this by setting the inode number of the index to zero, which means unused (zero is not a valid inode number).2. When fill_meta_index() is subsequently called again on another read operation, locate_meta_index() returns the previous index because it matches the inode number of 0. Because this index has been returned it is expected to have been filled, and because it hasn't been, an out of bounds access is performed.This patch adds a sanity check which checks that the inode numberis not zero when the inode is created and returns -EINVAL if it is.[phillip@squashfs.org.uk: whitespace fix]

Description: In the Linux kernel, the following vulnerability has been resolved:nvme: fix reconnection fail due to reserved tag allocationWe found a issue on production environment while using NVMe over RDMA,admin_q reconnect failed forever while remote target and network is ok.After dig into it, we found it may caused by a ABBA deadlock due to tagallocation. In my case, the tag was hold by a keep alive requestwaiting inside admin_q, as we quiesced admin_q while reset ctrl, so therequest maked as idle and will not process before reset success. Asfabric_q shares tagset with admin_q, while reconnect remote target, weneed a tag for connect command, but the only one reserved tag was heldby keep alive command which waiting inside admin_q. As a result, wefailed to reconnect admin_q forever. In order to fix this issue, Ithink we should keep two reserved tags for admin queue.

CVE-2024-35247 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fpga: region: add owner module and take its refcountThe current implementation of the fpga region assumes that the low-levelmodule registers a driver for the parent device and uses its owner pointerto take the module's refcount. This approach is problematic since it canlead to a null pointer dereference while attempting to get the regionduring programming if the parent device does not have a driver.To address this problem, add a module owner pointer to the fpga_regionstruct and use it to take the module's refcount. Modify the functions forregistering a region to take an additional owner module parameter andrename them to avoid conflicts. Use the old function names for helpermacros that automatically set the module that registers the region as theowner. This ensures compatibility with existing low-level control modulesand reduces the chances of registering a region without setting the owner.Also, update the documentation to keep it consistent with the new interfacefor registering an fpga region.

CVE-2024-35794 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:dm-raid: really frozen sync_thread during suspend1) commit f52f5c71f3d4 ("md: fix stopping sync thread") remove MD_RECOVERY_FROZEN from __md_stop_writes() and doesn't realize that dm-raid relies on __md_stop_writes() to frozen sync_thread indirectly. Fix this problem by adding MD_RECOVERY_FROZEN in md_stop_writes(), and since stop_sync_thread() is only used for dm-raid in this case, also move stop_sync_thread() to md_stop_writes().2) The flag MD_RECOVERY_FROZEN doesn't mean that sync thread is frozen, it only prevent new sync_thread to start, and it can't stop the running sync thread; In order to frozen sync_thread, after seting the flag, stop_sync_thread() should be used.3) The flag MD_RECOVERY_FROZEN doesn't mean that writes are stopped, use it as condition for md_stop_writes() in raid_postsuspend() doesn't look correct. Consider that reentrant stop_sync_thread() do nothing, always call md_stop_writes() in raid_postsuspend().4) raid_message can set/clear the flag MD_RECOVERY_FROZEN at anytime, and if MD_RECOVERY_FROZEN is cleared while the array is suspended, new sync_thread can start unexpected. Fix this by disallow raid_message() to change sync_thread status during suspend.Note that after commit f52f5c71f3d4 ("md: fix stopping sync thread"), thetest shell/lvconvert-raid-reshape.sh start to hang in stop_sync_thread(),and with previous fixes, the test won't hang there anymore, however, thetest will still fail and complain that ext4 is corrupted. And with thispatch, the test won't hang due to stop_sync_thread() or fail due to ext4is corrupted anymore. However, there is still a deadlock related todm-raid456 that will be fixed in following patches.

CVE-2024-35801 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:x86/fpu: Keep xfd_state in sync with MSR_IA32_XFDCommit 672365477ae8 ("x86/fpu: Update XFD state where required") andcommit 8bf26758ca96 ("x86/fpu: Add XFD state to fpstate") introduced aper CPU variable xfd_state to keep the MSR_IA32_XFD value cached, inorder to avoid unnecessary writes to the MSR.On CPU hotplug MSR_IA32_XFD is reset to the init_fpstate.xfd, whichwipes out any stale state. But the per CPU cached xfd value is notreset, which brings them out of sync.As a consequence a subsequent xfd_update_state() might fail to updatethe MSR which in turn can result in XRSTOR raising a #NM in kernelspace, which crashes the kernel.To fix this, introduce xfd_set_state() to write xfd_state togetherwith MSR_IA32_XFD, and use it in all places that set MSR_IA32_XFD.

CVE-2024-35804 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: x86: Mark target gfn of emulated atomic instruction as dirtyWhen emulating an atomic access on behalf of the guest, mark the targetgfn dirty if the CMPXCHG by KVM is attempted and doesn't fault. Thisfixes a bug where KVM effectively corrupts guest memory during livemigration by writing to guest memory without informing userspace that thepage is dirty.Marking the page dirty got unintentionally dropped when KVM's emulatedCMPXCHG was converted to do a user access. Before that, KVM explicitlymapped the guest page into kernel memory, and marked the page dirty duringthe unmap phase.Mark the page dirty even if the CMPXCHG fails, as the old data is writtenback on failure, i.e. the page is still written. The value written isguaranteed to be the same because the operation is atomic, but KVM's ABIis that all writes are dirty logged regardless of the value written. Andmore importantly, that's what KVM did before the buggy commit.Huge kudos to the folks on the Cc list (and many others), who did all theactual work of triaging and debugging.base-commit: 6769ea8da8a93ed4630f1ce64df6aafcaabfce64

CVE-2024-35807 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: fix corruption during on-line resizeWe observed a corruption during on-line resize of a file system that islarger than 16 TiB with 4k block size. With having more then 2^32 blocksresize_inode is turned off by default by mke2fs. The issue can bereproduced on a smaller file system for convenience by explicitlyturning off resize_inode. An on-line resize across an 8 GiB boundary (thesize of a meta block group in this setup) then leads to a corruption: dev=/dev/ # should be >= 16 GiB mkdir -p /corruption /sbin/mke2fs -t ext4 -b 4096 -O ^resize_inode $dev $((2 * 2**21 - 2**15)) mount -t ext4 $dev /corruption dd if=/dev/zero bs=4096 of=/corruption/test count=$((2*2**21 - 4*2**15)) sha1sum /corruption/test # 79d2658b39dcfd77274e435b0934028adafaab11 /corruption/test /sbin/resize2fs $dev $((2*2**21)) # drop page cache to force reload the block from disk echo 1 > /proc/sys/vm/drop_caches sha1sum /corruption/test # 3c2abc63cbf1a94c9e6977e0fbd72cd832c4d5c3 /corruption/test2^21 = 2^15*2^6 equals 8 GiB whereof 2^15 is the number of blocks perblock group and 2^6 are the number of block groups that make a metablock group.The last checksum might be different depending on how the file is laidout across the physical blocks. The actual corruption occurs at physicalblock 63*2^15 = 2064384 which would be the location of the backup of themeta block group's block descriptor. During the on-line resize the filesystem will be converted to meta_bg starting at s_first_meta_bg which is2 in the example - meaning all block groups after 16 GiB. However, inext4_flex_group_add we might add block groups that are not part of thefirst meta block group yet. In the reproducer we achieved this bysubstracting the size of a whole block group from the point where themeta block group would start. This must be considered when updating thebackup block group descriptors to follow the non-meta_bg layout. The fixis to add a test whether the group to add is already part of the metablock group or not.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: ncm: Fix handling of zero block length packetsWhile connecting to a Linux host with CDC_NCM_NTB_DEF_SIZE_TXset to 65536, it has been observed that we receive short packets,which come at interval of 5-10 seconds sometimes and have blocklength zero but still contain 1-2 valid datagrams present.According to the NCM spec:"If wBlockLength = 0x0000, the block is terminated by ashort packet. In this case, the USB transfer must stillbe shorter than dwNtbInMaxSize or dwNtbOutMaxSize. Ifexactly dwNtbInMaxSize or dwNtbOutMaxSize bytes are sent,and the size is a multiple of wMaxPacketSize for thegiven pipe, then no ZLP shall be sent.wBlockLength= 0x0000 must be used with extreme care, becauseof the possibility that the host and device may get out ofsync, and because of test issues.wBlockLength = 0x0000 allows the sender to reduce latency bystarting to send a very large NTB, and then shortening it whenthe sender discovers that there's not sufficient data to justifysending a large NTB"However, there is a potential issue with the current implementation,as it checks for the occurrence of multiple NTBs in a singlegiveback by verifying if the leftover bytes to be processed is zeroor not. If the block length reads zero, we would process the sameNTB infintely because the leftover bytes is never zero and it leadsto a crash. Fix this by bailing out if block length reads zero.

CVE-2024-35852 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mlxsw: spectrum_acl_tcam: Fix memory leak when canceling rehash workThe rehash delayed work is rescheduled with a delay if the number ofcredits at end of the work is not negative as supposedly it means thatthe migration ended. Otherwise, it is rescheduled immediately.After "mlxsw: spectrum_acl_tcam: Fix possible use-after-free duringrehash" the above is no longer accurate as a non-negative number ofcredits is no longer indicative of the migration being done. It can alsohappen if the work encountered an error in which case the migration willresume the next time the work is scheduled.The significance of the above is that it is possible for the work to bepending and associated with hints that were allocated when the migrationstarted. This leads to the hints being leaked [1] when the work iscanceled while pending as part of ACL region dismantle.Fix by freeing the hints if hints are associated with a work that wascanceled while pending.Blame the original commit since the reliance on not having a pendingwork associated with hints is fragile.[1]unreferenced object 0xffff88810e7c3000 (size 256): comm "kworker/0:16", pid 176, jiffies 4295460353 hex dump (first 32 bytes): 00 30 95 11 81 88 ff ff 61 00 00 00 00 00 00 80 .0......a....... 00 00 61 00 40 00 00 00 00 00 00 00 04 00 00 00 ..a.@........... backtrace (crc 2544ddb9): [<00000000cf8cfab3>] kmalloc_trace+0x23f/0x2a0 [<000000004d9a1ad9>] objagg_hints_get+0x42/0x390 [<000000000b143cf3>] mlxsw_sp_acl_erp_rehash_hints_get+0xca/0x400 [<0000000059bdb60a>] mlxsw_sp_acl_tcam_vregion_rehash_work+0x868/0x1160 [<00000000e81fd734>] process_one_work+0x59c/0xf20 [<00000000ceee9e81>] worker_thread+0x799/0x12c0 [<00000000bda6fe39>] kthread+0x246/0x300 [<0000000070056d23>] ret_from_fork+0x34/0x70 [<00000000dea2b93e>] ret_from_fork_asm+0x1a/0x30

CVE-2024-35853 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mlxsw: spectrum_acl_tcam: Fix memory leak during rehashThe rehash delayed work migrates filters from one region to another.This is done by iterating over all chunks (all the filters with the samepriority) in the region and in each chunk iterating over all thefilters.If the migration fails, the code tries to migrate the filters back tothe old region. However, the rollback itself can also fail in which caseanother migration will be erroneously performed. Besides the fact thatthis ping pong is not a very good idea, it also creates a problem.Each virtual chunk references two chunks: The currently used one('vchunk->chunk') and a backup ('vchunk->chunk2'). During migration thefirst holds the chunk we want to migrate filters to and the second holdsthe chunk we are migrating filters from.The code currently assumes - but does not verify - that the backup chunkdoes not exist (NULL) if the currently used chunk does not reference thetarget region. This assumption breaks when we are trying to rollback arollback, resulting in the backup chunk being overwritten and leaked[1].Fix by not rolling back a failed rollback and add a warning to avoidfuture cases.[1]WARNING: CPU: 5 PID: 1063 at lib/parman.c:291 parman_destroy+0x17/0x20Modules linked in:CPU: 5 PID: 1063 Comm: kworker/5:11 Tainted: G W 6.9.0-rc2-custom-00784-gc6a05c468a0b #14Hardware name: Mellanox Technologies Ltd.

CVE-2024-35870 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: fix UAF in smb2_reconnect_server()The UAF bug is due to smb2_reconnect_server() accessing a session thatis already being teared down by another thread that is executing__cifs_put_smb_ses(). This can happen when (a) the client hasconnection to the server but no session or (b) another thread ends upsetting @ses->ses_status again to something different thanSES_EXITING.To fix this, we need to make sure to unconditionally set@ses->ses_status to SES_EXITING and prevent any other threads fromsetting a new status while we're still tearing it down.The following can be reproduced by adding some delay to right afterthe ipc is freed in __cifs_put_smb_ses() - which will givesmb2_reconnect_server() worker a chance to run and then accessing@ses->ipc:kinit ...mount.cifs //srv/share /mnt/1 -o sec=krb5,nohandlecache,echo_interval=10[disconnect srv]ls /mnt/1 &>/dev/nullsleep 30kdestroy[reconnect srv]sleep 10umount /mnt/1...CIFS: VFS: Verify user has a krb5 ticket and keyutils is installedCIFS: VFS: \\srv Send error in SessSetup = -126CIFS: VFS: Verify user has a krb5 ticket and keyutils is installedCIFS: VFS: \\srv Send error in SessSetup = -126general protection fault, probably for non-canonical address0x6b6b6b6b6b6b6b6b: 0000 [#1] PREEMPT SMP NOPTICPU: 3 PID: 50 Comm: kworker/3:1 Not tainted 6.9.0-rc2 #1Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-1.fc3904/01/2014Workqueue: cifsiod smb2_reconnect_server [cifs]RIP: 0010:__list_del_entry_valid_or_report+0x33/0xf0Code: 4f 08 48 85 d2 74 42 48 85 c9 74 59 48 b8 00 01 00 00 00 00 adde 48 39 c2 74 61 48 b8 22 01 00 00 00 00 74 69 <48> 8b 01 48 39 f8 757b 48 8b 72 08 48 39 c6 0f 85 88 00 00 00 b8RSP: 0018:ffffc900001bfd70 EFLAGS: 00010a83RAX: dead000000000122 RBX: ffff88810da53838 RCX: 6b6b6b6b6b6b6b6bRDX: 6b6b6b6b6b6b6b6b RSI: ffffffffc02f6878 RDI: ffff88810da53800RBP: ffff88810da53800 R08: 0000000000000001 R09: 0000000000000000R10: 0000000000000000 R11: 0000000000000001 R12: ffff88810c064000R13: 0000000000000001 R14: ffff88810c064000 R15: ffff8881039cc000FS: 0000000000000000(0000) GS:ffff888157c00000(0000)knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007fe3728b1000 CR3: 000000010caa4000 CR4: 0000000000750ef0PKRU: 55555554Call Trace: ? die_addr+0x36/0x90 ? exc_general_protection+0x1c1/0x3f0 ? asm_exc_general_protection+0x26/0x30 ? __list_del_entry_valid_or_report+0x33/0xf0 __cifs_put_smb_ses+0x1ae/0x500 [cifs] smb2_reconnect_server+0x4ed/0x710 [cifs] process_one_work+0x205/0x6b0 worker_thread+0x191/0x360 ? __pfx_worker_thread+0x10/0x10 kthread+0xe2/0x110 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x34/0x50 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1a/0x30

Description: In the Linux kernel, the following vulnerability has been resolved:mm/secretmem: fix GUP-fast succeeding on secretmem foliosfolio_is_secretmem() currently relies on secretmem folios being LRUfolios, to save some cycles.However, folios might reside in a folio batch without the LRU flag set, ortemporarily have their LRU flag cleared. Consequently, the LRU flag isunreliable for this purpose.In particular, this is the case when secretmem_fault() allocates a freshpage and calls filemap_add_folio()->folio_add_lru(). The folio might beadded to the per-cpu folio batch and won't get the LRU flag set until thebatch was drained using e.g., lru_add_drain().Consequently, folio_is_secretmem() might not detect secretmem folios andGUP-fast can succeed in grabbing a secretmem folio, crashing the kernelwhen we would later try reading/writing to the folio, because the foliohas been unmapped from the directmap.Fix it by removing that unreliable check.

Description: In the Linux kernel, the following vulnerability has been resolved:x86/mm/pat: fix VM_PAT handling in COW mappingsPAT handling won't do the right thing in COW mappings: the first PTE (or,in fact, all PTEs) can be replaced during write faults to point at anonfolios. Reliably recovering the correct PFN and cachemode usingfollow_phys() from PTEs will not work in COW mappings.Using follow_phys(), we might just get the address+protection of the anonfolio (which is very wrong), or fail on swap/nonswap entries, failingfollow_phys() and triggering a WARN_ON_ONCE() in untrack_pfn() andtrack_pfn_copy(), not properly calling free_pfn_range().In free_pfn_range(), we either wouldn't call memtype_free() or would callit with the wrong range, possibly leaking memory.To fix that, let's update follow_phys() to refuse returning anon folios,and fallback to using the stored PFN inside vma->vm_pgoff for COW mappingsif we run into that.We will now properly handle untrack_pfn() with COW mappings, where wedon't need the cachemode. We'll have to fail fork()->track_pfn_copy() ifthe first page was replaced by an anon folio, though: we'd have to storethe cachemode in the VMA to make this work, likely growing the VMA size.For now, lets keep it simple and let track_pfn_copy() just fail in thatcase: it would have failed in the past with swap/nonswap entries already,and it would have done the wrong thing with anon folios.Simple reproducer to trigger the WARN_ON_ONCE() in untrack_pfn():<--- C reproducer ---> #include #include #include #include int main(void) { struct io_uring_params p = {}; int ring_fd; size_t size; char *map; ring_fd = io_uring_setup(1, &p); if (ring_fd < 0) { perror("io_uring_setup"); return 1; } size = p.sq_off.array + p.sq_entries * sizeof(unsigned); /* Map the submission queue ring MAP_PRIVATE */ map = mmap(0, size, PROT_READ | PROT_WRITE, MAP_PRIVATE, ring_fd, IORING_OFF_SQ_RING); if (map == MAP_FAILED) { perror("mmap"); return 1; } /* We have at least one page.

Description: In the Linux kernel, the following vulnerability has been resolved:of: dynamic: Synchronize of_changeset_destroy() with the devlink removalsIn the following sequence: 1) of_platform_depopulate() 2) of_overlay_remove()During the step 1, devices are destroyed and devlinks are removed.During the step 2, OF nodes are destroyed but__of_changeset_entry_destroy() can raise warnings related to missingof_node_put(): ERROR: memory leak, expected refcount 1 instead of 2 ...Indeed, during the devlink removals performed at step 1, the removalitself releasing the device (and the attached of_node) is done by a jobqueued in a workqueue and so, it is done asynchronously with respect tofunction calls.When the warning is present, of_node_put() will be called but wronglytoo late from the workqueue job.In order to be sure that any ongoing devlink removals are done beforethe of_node destruction, synchronize the of_changeset_destroy() with thedevlink removals.

CVE-2024-35884 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:udp: do not accept non-tunnel GSO skbs landing in a tunnelWhen rx-udp-gro-forwarding is enabled UDP packets might be GROed whenbeing forwarded. If such packets might land in a tunnel this can causevarious issues and udp_gro_receive makes sure this isn't the case bylooking for a matching socket. This is performed inudp4/6_gro_lookup_skb but only in the current netns. This is an issuewith tunneled packets when the endpoint is in another netns. In suchcases the packets will be GROed at the UDP level, which leads to variousissues later on. The same thing can happen with rx-gro-list.We saw this with geneve packets being GROed at the UDP level. In suchcase gso_size is set; later the packet goes through the geneve rx path,the geneve header is pulled, the offset are adjusted and frag_list skbsare not adjusted with regard to geneve. When those skbs hitskb_fragment, it will misbehave. Different outcomes are possibledepending on what the GROed skbs look like; from corrupted packets tokernel crashes.One example is a BUG_ON[1] triggered in skb_segment while processing thefrag_list. Because gso_size is wrong (geneve header was pulled)skb_segment thinks there is "geneve header size" of data in frag_list,although it's in fact the next packet. The BUG_ON itself has nothing todo with the issue. This is only one of the potential issues.Looking up for a matching socket in udp_gro_receive is fragile: thelookup could be extended to all netns (not speaking about performances)but nothing prevents those packets from being modified in between and wecould still not find a matching socket. It's OK to keep the currentlogic there as it should cover most cases but we also need to make surewe handle tunnel packets being GROed too early.This is done by extending the checks in udp_unexpected_gso: GSO packetslacking the SKB_GSO_UDP_TUNNEL/_CSUM bits and landing in a tunnel mustbe segmented.[1] kernel BUG at net/core/skbuff.c:4408!

CVE-2024-35910 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:tcp: properly terminate timers for kernel socketsWe had various syzbot reports about tcp timers firing afterthe corresponding netns has been dismantled.Fortunately Josef Bacik could trigger the issue more often,and could test a patch I wrote two years ago.When TCP sockets are closed, we call inet_csk_clear_xmit_timers()to 'stop' the timers.inet_csk_clear_xmit_timers() can be called from any context,including when socket lock is held.This is the reason it uses sk_stop_timer(), aka del_timer().This means that ongoing timers might finish much later.For user sockets, this is fine because each running timerholds a reference on the socket, and the user socket holdsa reference on the netns.For kernel sockets, we risk that the netns is freed beforetimer can complete, because kernel sockets do not holdreference on the netns.This patch adds inet_csk_clear_xmit_timers_sync() functionthat using sk_stop_timer_sync() to make sure all timersare terminated before the kernel socket is released.Modules using kernel sockets close them in their netns exit()handler.Also add sock_not_owned_by_me() helper to get LOCKDEPsupport : inet_csk_clear_xmit_timers_sync() must not be calledwhile socket lock is held.It is very possible we can revert in the future commit3a58f13a881e ("net: rds: acquire refcount on TCP sockets")which attempted to solve the issue in rds only.(net/smc/af_smc.c and net/mptcp/subflow.c have similar code)We probably can remove the check_net() tests fromtcp_out_of_resources() and __tcp_close() in the future.

When the payloadlength is zero, each message type handler reads uninitialized payloadand KMSAN detects this issue. The receipt of a packet with a zero-sizepayload is considered unexpected, and therefore, such packets should besilently discarded.This patch resolved this issue by checking payload size before callingeach message type handler codes.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: handle chunk tree lookup error in btrfs_relocate_sys_chunks()The unhandled case in btrfs_relocate_sys_chunks() loop is a corruption,as it could be caused only by two impossible conditions:- at first the search key is set up to look for a chunk tree item, with offset -1, this is an inexact search and the key->offset will contain the correct offset upon a successful search, a valid chunk tree item cannot have an offset -1- after first successful search, the found_key corresponds to a chunk item, the offset is decremented by 1 before the next loop, it's impossible to find a chunk item there due to alignment and size constraints

Description: In the Linux kernel, the following vulnerability has been resolved:drm/ast: Fix soft lockupThere is a while-loop in ast_dp_set_on_off() that could lead toinfinite-loop. This is because the register, VGACRI-Dx, checked inthis API is a scratch register actually controlled by a MCU, namedDPMCU, in BMC.These scratch registers are protected by scu-lock. If suc-lock is notoff, DPMCU can not update these registers and then host will have softlockup due to never updated status.DPMCU is used to control DP and relative registers to handshake withhost's VGA driver. Even the most time-consuming task, DP's linktraining, is less than 100ms. 200ms should be enough.

CVE-2024-35955 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:kprobes: Fix possible use-after-free issue on kprobe registrationWhen unloading a module, its state is changing MODULE_STATE_LIVE -> MODULE_STATE_GOING -> MODULE_STATE_UNFORMED. Each change will takea time. `is_module_text_address()` and `__module_text_address()`works with MODULE_STATE_LIVE and MODULE_STATE_GOING.If we use `is_module_text_address()` and `__module_text_address()`separately, there is a chance that the first one is succeeded but thenext one is failed because module->state becomes MODULE_STATE_UNFORMEDbetween those operations.In `check_kprobe_address_safe()`, if the second `__module_text_address()`is failed, that is ignored because it expected a kernel_text address.But it may have failed simply because module->state has been changedto MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modifynon-exist module text address (use-after-free).To fix this problem, we should not use separated `is_module_text_address()`and `__module_text_address()`, but use only `__module_text_address()`once and do `try_module_get(module)` which is only available withMODULE_STATE_LIVE.

CVE-2024-35982 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:batman-adv: Avoid infinite loop trying to resize local TTIf the MTU of one of an attached interface becomes too small to transmitthe local translation table then it must be resized to fit inside allfragments (when enabled) or a single packet.But if the MTU becomes too low to transmit even the header + the VLANspecific part then the resizing of the local TT will never succeed. Thiscan for example happen when the usable space is 110 bytes and 11 VLANs areon top of batman-adv. In this case, at least 116 byte would be needed.There will just be an endless spam of batman_adv: batadv0: Forced to purge local tt entries to fit new maximum fragment MTU (110)in the log but the function will never finish. Problem here is that thetimeout will be halved all the time and will then stagnate at 0 andtherefore never be able to reduce the table even more.There are other scenarios possible with a similar result. The number ofBATADV_TT_CLIENT_NOPURGE entries in the local TT can for example be toohigh to fit inside a packet. Such a scenario can therefore happen also withonly a single VLAN + 7 non-purgable addresses - requiring at least 120bytes.While this should be handled proactively when:* interface with too low MTU is added* VLAN is added* non-purgeable local mac is added* MTU of an attached interface is reduced* fragmentation setting gets disabled (which most likely requires dropping attached interfaces)not all of these scenarios can be prevented because batman-adv is onlyconsuming events without the the possibility to prevent these actions(non-purgable MAC address added, MTU of an attached interface is reduced).It is therefore necessary to also make sure that the code is able to handlealso the situations when there were already incompatible systemconfiguration are present.

CVE-2024-36479 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fpga: bridge: add owner module and take its refcountThe current implementation of the fpga bridge assumes that the low-levelmodule registers a driver for the parent device and uses its owner pointerto take the module's refcount. This approach is problematic since it canlead to a null pointer dereference while attempting to get the bridge ifthe parent device does not have a driver.To address this problem, add a module owner pointer to the fpga_bridgestruct and use it to take the module's refcount. Modify the function forregistering a bridge to take an additional owner module parameter andrename it to avoid conflicts. Use the old function name for a helper macrothat automatically sets the module that registers the bridge as the owner.This ensures compatibility with existing low-level control modules andreduces the chances of registering a bridge without setting the owner.Also, update the documentation to keep it consistent with the new interfacefor registering an fpga bridge.Other changes: opportunistically move put_device() from __fpga_bridge_get()to fpga_bridge_get() and of_fpga_bridge_get() to improve code clarity sincethe bridge device is taken in these functions.

CVE-2024-37021 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fpga: manager: add owner module and take its refcountThe current implementation of the fpga manager assumes that the low-levelmodule registers a driver for the parent device and uses its owner pointerto take the module's refcount. This approach is problematic since it canlead to a null pointer dereference while attempting to get the manager ifthe parent device does not have a driver.To address this problem, add a module owner pointer to the fpga_managerstruct and use it to take the module's refcount. Modify the functions forregistering the manager to take an additional owner module parameter andrename them to avoid conflicts. Use the old function names for helpermacros that automatically set the module that registers the manager as theowner. This ensures compatibility with existing low-level control modulesand reduces the chances of registering a manager without setting the owner.Also, update the documentation to keep it consistent with the new interfacefor registering an fpga manager.Other changes: opportunistically move put_device() from __fpga_mgr_get() tofpga_mgr_get() and of_fpga_mgr_get() to improve code clarity since themanager device is taken in these functions.

Description: In the Linux kernel, the following vulnerability has been resolved:media: stk1160: fix bounds checking in stk1160_copy_video()The subtract in this condition is reversed. The ->length is the lengthof the buffer. The ->bytesused is how many bytes we have copied thusfar. When the condition is reversed that means the result of thesubtraction is always negative but since it's unsigned then the resultis a very high positive value. That means the overflow check is nevertrue.Additionally, the ->bytesused doesn't actually work for this purposebecause we're not writing to "buf->mem + buf->bytesused". Instead, themath to calculate the destination where we are writing is a bitinvolved. You calculate the number of full lines already written,multiply by two, skip a line if necessary so that we start on an oddnumbered line, and add the offset into the line.To fix this buffer overflow, just take the actual destination where weare writing, if the offset is already out of bounds print an error andreturn. Otherwise, write up to buf->length bytes.

CVE-2024-39488 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:arm64: asm-bug: Add .align 2 to the end of __BUG_ENTRYWhen CONFIG_DEBUG_BUGVERBOSE=n, we fail to add necessary padding bytesto bug_table entries, and as a result the last entry in a bug table willbe ignored, potentially leading to an unexpected panic(). All priorentries in the table will be handled correctly.The arm64 ABI requires that struct fields of up to 8 bytes arenaturally-aligned, with padding added within a struct such that structare suitably aligned within arrays.When CONFIG_DEBUG_BUGVERPOSE=y, the layout of a bug_entry is: struct bug_entry { signed int bug_addr_disp; // 4 bytes signed int file_disp; // 4 bytes unsigned short line; // 2 bytes unsigned short flags; // 2 bytes }... with 12 bytes total, requiring 4-byte alignment.When CONFIG_DEBUG_BUGVERBOSE=n, the layout of a bug_entry is: struct bug_entry { signed int bug_addr_disp; // 4 bytes unsigned short flags; // 2 bytes < implicit padding > // 2 bytes }... with 8 bytes total, with 6 bytes of data and 2 bytes of trailingpadding, requiring 4-byte alginment.When we create a bug_entry in assembly, we align the start of the entryto 4 bytes, which implicitly handles padding for any prior entries.However, we do not align the end of the entry, and so whenCONFIG_DEBUG_BUGVERBOSE=n, the final entry lacks the trailing paddingbytes.For the main kernel image this is not a problem as find_bug() doesn'tdepend on the trailing padding bytes when searching for entries: for (bug = __start___bug_table; bug < __stop___bug_table; ++bug) if (bugaddr == bug_addr(bug)) return bug;However for modules, module_bug_finalize() depends on the trailingbytes when calculating the number of entries: mod->num_bugs = sechdrs[i].sh_size / sizeof(struct bug_entry);... and as the last bug_entry lacks the necessary padding bytes, this entrywill not be counted, e.g. in the case of a single entry: sechdrs[i].sh_size == 6 sizeof(struct bug_entry) == 8; sechdrs[i].sh_size / sizeof(struct bug_entry) == 0;Consequently module_find_bug() will miss the last bug_entry when it does: for (i = 0; i < mod->num_bugs; ++i, ++bug) if (bugaddr == bug_addr(bug)) goto out;... which can lead to a kenrel panic due to an unhandled bug.This can be demonstrated with the following module: static int __init buginit(void) { WARN(1, "hello\n"); return 0; } static void __exit bugexit(void) { } module_init(buginit); module_exit(bugexit); MODULE_LICENSE("GPL");... which will trigger a kernel panic when loaded: ------------[ cut here ]------------ hello Unexpected kernel BRK exception at EL1 Internal error: BRK handler: 00000000f2000800 [#1] PREEMPT SMP Modules linked in: hello(O+) CPU: 0 PID: 50 Comm: insmod Tainted: G O 6.9.1 #8 Hardware name: linux,dummy-virt (DT) pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : buginit+0x18/0x1000 [hello] lr : buginit+0x18/0x1000 [hello] sp : ffff800080533ae0 x29: ffff800080533ae0 x28: 0000000000000000 x27: 0000000000000000 x26: ffffaba8c4e70510 x25: ffff800080533c30 x24: ffffaba8c4a28a58 x23: 0000000000000000 x22: 0000000000000000 x21: ffff3947c0eab3c0 x20: ffffaba8c4e3f000 x19: ffffaba846464000 x18: 0000000000000006 x17: 0000000000000000 x16: ffffaba8c2492834 x15: 0720072007200720 x14: 0720072007200720 x13: ffffaba8c49b27c8 x12: 0000000000000312 x11: 0000000000000106 x10: ffffaba8c4a0a7c8 x9 : ffffaba8c49b27c8 x8 : 00000000ffffefff x7 : ffffaba8c4a0a7c8 x6 : 80000000fffff000 x5 : 0000000000000107 x4 : 0000000000000000 x3 : 0000000000000000 x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff3947c0eab3c0 Call trace: buginit+0x18/0x1000 [hello] do_one_initcall+0x80/0x1c8 do_init_module+0x60/0x218 load_module+0x1ba4/0x1d70 __do_sys_init_module+0x198/0x1d0 __arm64_sys_init_module+0x1c/0x28 invoke_syscall+0x48/0x114 el0_svc---truncated---

CVE-2024-39506 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:liquidio: Adjust a NULL pointer handling path in lio_vf_rep_copy_packetIn lio_vf_rep_copy_packet() pg_info->page is compared to a NULL value,but then it is unconditionally passed to skb_add_rx_frag() which looksstrange and could lead to null pointer dereference.lio_vf_rep_copy_packet() call trace looks like: octeon_droq_process_packets octeon_droq_fast_process_packets octeon_droq_dispatch_pkt octeon_create_recv_info ...search in the dispatch_list... ->disp_fn(rdisp->rinfo, ...) lio_vf_rep_pkt_recv(struct octeon_recv_info *recv_info, ...)In this path there is no code which sets pg_info->page to NULL.So this check looks unneeded and doesn't solve potential problem.But I guess the author had reason to add a check and I have no such cardand can't do real test.In addition, the code in the function liquidio_push_packet() inliquidio/lio_core.c does exactly the same.Based on this, I consider the most acceptable compromise solution toadjust this issue by moving skb_add_rx_frag() into conditional scope.Found by Linux Verification Center (linuxtesting.org) with SVACE.

CVE-2024-40970 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:Avoid hw_desc array overrun in dw-axi-dmacI have a use case where nr_buffers = 3 and in which each descriptor is composed by 3segments, resulting in the DMA channel descs_allocated to be 9. Since axi_desc_put()handles the hw_desc considering the descs_allocated, this scenario would result in akernel panic (hw_desc array will be overrun).To fix this, the proposal is to add a new member to the axi_dma_desc structure,where we keep the number of allocated hw_descs (axi_desc_alloc()) and use it inaxi_desc_put() to handle the hw_desc array correctly.Additionally I propose to remove the axi_chan_start_first_queued() call after completingthe transfer, since it was identified that unbalance can occur (started descriptors canbe interrupted and transfer ignored due to DMA channel not being enabled).

CVE-2024-40984 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ACPICA: Revert "ACPICA: avoid Info: mapping multiple BARs. Your kernel is fine."Undo the modifications made in commit d410ee5109a1 ("ACPICA: avoid"Info: mapping multiple BARs. Your kernel is fine.""). The initialpurpose of this commit was to stop memory mappings for operationregions from overlapping page boundaries, as it can trigger warningsif different page attributes are present.However, it was found that when this situation arises, mappingcontinues until the boundary's end, but there is still an attempt toread/write the entire length of the map, leading to a NULL pointerdeference. For example, if a four-byte mapping request is made butonly one byte is mapped because it hits the current page boundary'send, a four-byte read/write attempt is still made, resulting in a NULLpointer deference.Instead, map the entire length, as the ACPI specification does notmandate that it must be within the same page boundary. It ispermissible for it to be mapped across different regions.

CVE-2024-41035 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:USB: core: Fix duplicate endpoint bug by clearing reserved bits in the descriptorSyzbot has identified a bug in usbcore (see the Closes: tag below)caused by our assumption that the reserved bits in an endpointdescriptor's bEndpointAddress field will always be 0. As a result ofthe bug, the endpoint_is_duplicate() routine in config.c (and possiblyother routines as well) may believe that two descriptors are fordistinct endpoints, even though they have the same direction andendpoint number. This can lead to confusion, including the bugidentified by syzbot (two descriptors with matching endpoint numbersand directions, where one was interrupt and the other was bulk).To fix the bug, we will clear the reserved bits in bEndpointAddresswhen we parse the descriptor. (Note that both the USB-2.0 and USB-3.1specs say these bits are "Reserved, reset to zero".) This requires usto make a copy of the descriptor earlier in usb_parse_endpoint() anduse the copy instead of the original when checking for duplicates.

Though, the target implemention returns 0 for TCPand FC but not for RDMA.Let's make RDMA behave the same and thus explicitly initializing theresult field. This prevents leaking any data from the stack.

CVE-2024-41080 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring: fix possible deadlock in io_register_iowq_max_workers()The io_register_iowq_max_workers() function calls io_put_sq_data(),which acquires the sqd->lock without releasing the uring_lock.Similar to the commit 009ad9f0c6ee ("io_uring: drop ctx->uring_lockbefore acquiring sqd->lock"), this can lead to a potential deadlocksituation.To resolve this issue, the uring_lock is released before callingio_put_sq_data(), and then it is re-acquired after the function call.This change ensures that the locks are acquired in the correctorder, preventing the possibility of a deadlock.

CVE-2024-41088 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:can: mcp251xfd: fix infinite loop when xmit failsWhen the mcp251xfd_start_xmit() function fails, the driver stopsprocessing messages, and the interrupt routine does not return,running indefinitely even after killing the running application.Error messages:[ 441.298819] mcp251xfd spi2.0 can0: ERROR in mcp251xfd_start_xmit: -16[ 441.306498] mcp251xfd spi2.0 can0: Transmit Event FIFO buffer not empty. (seq=0x000017c7, tef_tail=0x000017cf, tef_head=0x000017d0, tx_head=0x000017d3).... and repeat forever.The issue can be triggered when multiple devices share the same SPIinterface. And there is concurrent access to the bus.The problem occurs because tx_ring->head increments even ifmcp251xfd_start_xmit() fails. Consequently, the driver skips one TXpackage while still expecting a response inmcp251xfd_handle_tefif_one().Resolve the issue by starting a workqueue to write the tx objsynchronously if err = -EBUSY. In case of another error, decrementtx_ring->head, remove skb from the echo stack, and drop the message.[mkl: use more imperative wording in patch description]

Description: In the Linux kernel, the following vulnerability has been resolved:xdp: Remove WARN() from __xdp_reg_mem_model()syzkaller reports a warning in __xdp_reg_mem_model().The warning occurs only if __mem_id_init_hash_table() returns an error. Itreturns the error in two cases: 1. memory allocation fails; 2. rhashtable_init() fails when some fields of rhashtable_params struct are not initialized properly.The second case cannot happen since there is a static const rhashtable_paramsstruct with valid fields. So, warning is only triggered when there is aproblem with memory allocation.Thus, there is no sense in using WARN() to handle this error and it can besafely removed.WARNING: CPU: 0 PID: 5065 at net/core/xdp.c:299 __xdp_reg_mem_model+0x2d9/0x650 net/core/xdp.c:299CPU: 0 PID: 5065 Comm: syz-executor883 Not tainted 6.8.0-syzkaller-05271-gf99c5f563c17 #0Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 03/27/2024RIP: 0010:__xdp_reg_mem_model+0x2d9/0x650 net/core/xdp.c:299Call Trace: xdp_reg_mem_model+0x22/0x40 net/core/xdp.c:344 xdp_test_run_setup net/bpf/test_run.c:188 [inline] bpf_test_run_xdp_live+0x365/0x1e90 net/bpf/test_run.c:377 bpf_prog_test_run_xdp+0x813/0x11b0 net/bpf/test_run.c:1267 bpf_prog_test_run+0x33a/0x3b0 kernel/bpf/syscall.c:4240 __sys_bpf+0x48d/0x810 kernel/bpf/syscall.c:5649 __do_sys_bpf kernel/bpf/syscall.c:5738 [inline] __se_sys_bpf kernel/bpf/syscall.c:5736 [inline] __x64_sys_bpf+0x7c/0x90 kernel/bpf/syscall.c:5736 do_syscall_64+0xfb/0x240 entry_SYSCALL_64_after_hwframe+0x6d/0x75Found by Linux Verification Center (linuxtesting.org) with syzkaller.

Description: In the Linux kernel, the following vulnerability has been resolved:ice: Don't process extts if PTP is disabledThe ice_ptp_extts_event() function can race with ice_ptp_release() andresult in a NULL pointer dereference which leads to a kernel panic.Panic occurs because the ice_ptp_extts_event() function callsptp_clock_event() with a NULL pointer. The ice driver has alreadyreleased the PTP clock by the time the interrupt for the next externaltimestamp event occurs.To fix this, modify the ice_ptp_extts_event() function to check thePTP state and bail early if PTP is not ready.

CVE-2024-42148 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bnx2x: Fix multiple UBSAN array-index-out-of-boundsFix UBSAN warnings that occur when using a system with 32 physicalcpu cores or more, or when the user defines a number of Ethernetqueues greater than or equal to FP_SB_MAX_E1x using the num_queuesmodule parameter.Currently there is a read/write out of bounds that occurs on the array"struct stats_query_entry query" present inside the "bnx2x_fw_stats_req"struct in "drivers/net/ethernet/broadcom/bnx2x/bnx2x.h".Looking at the definition of the "struct stats_query_entry query" array:struct stats_query_entry query[FP_SB_MAX_E1x+ BNX2X_FIRST_QUEUE_QUERY_IDX];FP_SB_MAX_E1x is defined as the maximum number of fast path interrupts andhas a value of 16, while BNX2X_FIRST_QUEUE_QUERY_IDX has a value of 3meaning the array has a total size of 19.Since accesses to "struct stats_query_entry query" are offset-ted byBNX2X_FIRST_QUEUE_QUERY_IDX, that means that the total number of Ethernetqueues should not exceed FP_SB_MAX_E1x (16). However one of these queuesis reserved for FCOE and thus the number of Ethernet queues should be setto [FP_SB_MAX_E1x -1] (15) if FCOE is enabled or [FP_SB_MAX_E1x] (16) ifit is not.This is also described in a comment in the source code indrivers/net/ethernet/broadcom/bnx2x/bnx2x.h just above the Macro definitionof FP_SB_MAX_E1x. Below is the part of this explanation that it importantfor this patch/* * The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is * control by the number of fast-path status blocks supported by the * device (HW/FW). Each fast-path status block (FP-SB) aka non-default * status block represents an independent interrupts context that can * serve a regular L2 networking queue. However special L2 queues such * as the FCoE queue do not require a FP-SB and other components like * the CNIC may consume FP-SB reducing the number of possible L2 queues * * If the maximum number of FP-SB available is X then: * a. If CNIC is supported it consumes 1 FP-SB thus the max number of * regular L2 queues is Y=X-1 * b. In MF mode the actual number of L2 queues is Y= (X-1/MF_factor) * c. If the FCoE L2 queue is supported the actual number of L2 queues * is Y+1 * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for * slow-path interrupts) or Y+2 if CNIC is supported (one additional * FP interrupt context for the CNIC). * e. The number of HW context (CID count) is always X or X+1 if FCoE * L2 queue is supported. The cid for the FCoE L2 queue is always X. */However this driver also supports NICs that use the E2 controller which canhandle more queues due to having more FP-SB represented by FP_SB_MAX_E2.Looking at the commits when the E2 support was added, it was originallyusing the E1x parameters: commit f2e0899f0f27 ("bnx2x: Add 57712 support").Back then FP_SB_MAX_E2 was set to 16 the same as E1x. However the driverwas later updated to take full advantage of the E2 instead of having it belimited to the capabilities of the E1x. But as far as we can tell, thearray "stats_query_entry query" was still limited to using the FP-SBavailable to the E1x cards as part of an oversignt when the driver wasupdated to take full advantage of the E2, and now with the driver beingaware of the greater queue size supported by E2 NICs, it causes the UBSANwarnings seen in the stack traces below.This patch increases the size of the "stats_query_entry query" array byreplacing FP_SB_MAX_E1x with FP_SB_MAX_E2 to be large enough to handleboth types of NICs.Stack traces:UBSAN: array-index-out-of-bounds in drivers/net/ethernet/broadcom/bnx2x/bnx2x_stats.c:1529:11index 20 is out of range for type 'stats_query_entry [19]'CPU: 12 PID: 858 Comm: systemd-network Not tainted 6.9.0-060900rc7-generic #202405052133Hardware name: HP ProLiant DL360 Gen9/ProLiant DL360 ---truncated---

CVE-2024-42246 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net, sunrpc: Remap EPERM in case of connection failure in xs_tcp_setup_socketWhen using a BPF program on kernel_connect(), the call can return -EPERM. Thiscauses xs_tcp_setup_socket() to loop forever, filling up the syslog and causingthe kernel to potentially freeze up.Neil suggested: This will propagate -EPERM up into other layers which might not be ready to handle it. It might be safer to map EPERM to an error we would be more likely to expect from the network system - such as ECONNREFUSED or ENETDOWN.ECONNREFUSED as error seems reasonable. For programs setting a different errorcan be out of reach (see handling in 4fbac77d2d09) in particular on kernelswhich do not have f10d05966196 ("bpf: Make BPF_PROG_RUN_ARRAY return -errinstead of allow boolean"), thus given that it is better to simply remap forconsistent behavior. UDP does handle EPERM in xs_udp_send_request().

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: handle inconsistent state in nilfs_btnode_create_block()Syzbot reported that a buffer state inconsistency was detected innilfs_btnode_create_block(), triggering a kernel bug.It is not appropriate to treat this inconsistency as a bug; it can occurif the argument block address (the buffer index of the newly createdblock) is a virtual block number and has been reallocated due tocorruption of the bitmap used to manage its allocation state.So, modify nilfs_btnode_create_block() and its callers to treat it as apossible filesystem error, rather than triggering a kernel bug.

CVE-2024-42304 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: make sure the first directory block is not a holeThe syzbot constructs a directory that has no dirblock but is non-inline,i.e. the first directory block is a hole. And no errors are reported whencreating files in this directory in the following flow. ext4_mknod ... ext4_add_entry // Read block 0 ext4_read_dirblock(dir, block, DIRENT) bh = ext4_bread(NULL, inode, block, 0) if (!bh && (type == INDEX || type == DIRENT_HTREE)) // The first directory block is a hole // But type == DIRENT, so no error is reported.After that, we get a directory block without '.' and '..' but with a validdentry. This may cause some code that relies on dot or dotdot (such asmake_indexed_dir()) to crash.Therefore when ext4_read_dirblock() finds that the first directory blockis a hole report that the filesystem is corrupted and return an error toavoid loading corrupted data from disk causing something bad.

CVE-2024-42305 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: check dot and dotdot of dx_root before making dir indexedSyzbot reports a issue as follows:============================================BUG: unable to handle page fault for address: ffffed11022e24fePGD 23ffee067 P4D 23ffee067 PUD 0Oops: Oops: 0000 [#1] PREEMPT SMP KASAN PTICPU: 0 PID: 5079 Comm: syz-executor306 Not tainted 6.10.0-rc5-g55027e689933 #0Call Trace: make_indexed_dir+0xdaf/0x13c0 fs/ext4/namei.c:2341 ext4_add_entry+0x222a/0x25d0 fs/ext4/namei.c:2451 ext4_rename fs/ext4/namei.c:3936 [inline] ext4_rename2+0x26e5/0x4370 fs/ext4/namei.c:4214[...]============================================The immediate cause of this problem is that there is only one valid dentryfor the block to be split during do_split, so split==0 results in out ofbounds accesses to the map triggering the issue. do_split unsigned split dx_make_map count = 1 split = count/2 = 0; continued = hash2 == map[split - 1].hash; ---> map[4294967295]The maximum length of a filename is 255 and the minimum block size is 1024,so it is always guaranteed that the number of entries is greater than orequal to 2 when do_split() is called.But syzbot's crafted image has no dot and dotdot in dir, and the dentrydistribution in dirblock is as follows: bus dentry1 hole dentry2 free|xx--|xx-------------|...............|xx-------------|...............|0 12 (8+248)=256 268 256 524 (8+256)=264 788 236 1024So when renaming dentry1 increases its name_len length by 1, neither holenor free is sufficient to hold the new dentry, and make_indexed_dir() iscalled.In make_indexed_dir() it is assumed that the first two entries of thedirblock must be dot and dotdot, so bus and dentry1 are left in dx_rootbecause they are treated as dot and dotdot, and only dentry2 is movedto the new leaf block. That's why count is equal to 1.Therefore add the ext4_check_dx_root() helper function to add more sanitychecks to dot and dotdot before starting the conversion to avoid the aboveissue.

CVE-2024-42306 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:udf: Avoid using corrupted block bitmap bufferWhen the filesystem block bitmap is corrupted, we detect the corruptionwhile loading the bitmap and fail the allocation with error. However thenext allocation from the same bitmap will notice the bitmap buffer isalready loaded and tries to allocate from the bitmap with mixed results(depending on the exact nature of the bitmap corruption). Fix theproblem by using BH_verified bit to indicate whether the bitmap is validor not.

CVE-2024-42318 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:landlock: Don't lose track of restrictions on cred_transferWhen a process' cred struct is replaced, this _almost_ always invokesthe cred_prepare LSM hook; but in one special case (whenKEYCTL_SESSION_TO_PARENT updates the parent's credentials), thecred_transfer LSM hook is used instead. Landlock only implements thecred_prepare hook, not cred_transfer, so KEYCTL_SESSION_TO_PARENT causesall information on Landlock restrictions to be lost.This basically means that a process with the ability to use the fork()and keyctl() syscalls can get rid of all Landlock restrictions onitself.Fix it by adding a cred_transfer hook that does the same thing as theexisting cred_prepare hook. (Implemented by having hook_cred_prepare()call hook_cred_transfer() so that the two functions are less likely toaccidentally diverge in the future.)

But this will lead to `libbpf_probe_bpf_prog_type`API broken which use verifier log to probe prog type and will lognothing if we reject invalid EXT prog before bpf_check().Another way is by adding null check in resolve_prog_type().The issue was introduced by commit 4a9c7bbe2ed4 ("bpf: Resolve toprog->aux->dst_prog->type only for BPF_PROG_TYPE_EXT") which wantedto correct type resolution for BPF_PROG_TYPE_TRACING programs. Beforethat, the type resolution of BPF_PROG_TYPE_EXT prog actually followsthe logic below: prog->aux->dst_prog ? prog->aux->dst_prog->type : prog->type;It implies that when EXT program is not yet attached to `dst_prog`,the prog type should be EXT itself. This code worked fine in the past.So just keep using it.Fix this by returning `prog->type` for BPF_PROG_TYPE_EXT if `dst_prog`is not present in resolve_prog_type().

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: virt_wifi: avoid reporting connection success with wrong SSIDWhen user issues a connection with a different SSID than the onevirt_wifi has advertised, the __cfg80211_connect_result() willtrigger the warning: WARN_ON(bss_not_found).The issue is because the connection code in virt_wifi does notcheck the SSID from user space (it only checks the BSSID), andvirt_wifi will call cfg80211_connect_result() with WLAN_STATUS_SUCCESSeven if the SSID is different from the one virt_wifi has advertised.Eventually cfg80211 won't be able to find the cfg80211_bss and generatethe warning.Fixed it by checking the SSID (from user space) in the connection code.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/vmwgfx: Fix a deadlock in dma buf fence pollingIntroduce a version of the fence ops that on release doesn't removethe fence from the pending list, and thus doesn't require a lock tofix poll->fence wait->fence unref deadlocks.vmwgfx overwrites the wait callback to iterate over the list of allfences and update their status, to do that it holds a lock to preventthe list modifcations from other threads. The fence destroy callbackboth deletes the fence and removes it from the list of pendingfences, for which it holds a lock.dma buf polling cb unrefs a fence after it's been signaled: so the pollcalls the wait, which signals the fences, which are being destroyed.The destruction tries to acquire the lock on the pending fences listwhich it can never get because it's held by the wait from which itwas called.Old bug, but not a lot of userspace apps were using dma-buf pollinginterfaces. Fix those, in particular this fixes KDE stalls/deadlock.

CVE-2024-43880 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mlxsw: spectrum_acl_erp: Fix object nesting warningACLs in Spectrum-2 and newer ASICs can reside in the algorithmic TCAM(A-TCAM) or in the ordinary circuit TCAM (C-TCAM). The former cancontain more ACLs (i.e., tc filters), but the number of masks in eachregion (i.e., tc chain) is limited.In order to mitigate the effects of the above limitation, the deviceallows filters to share a single mask if their masks only differ in upto 8 consecutive bits. For example, dst_ip/25 can be represented usingdst_ip/24 with a delta of 1 bit. The C-TCAM does not have a limit on thenumber of masks being used (and therefore does not support maskaggregation), but can contain a limited number of filters.The driver uses the "objagg" library to perform the mask aggregation bypassing it objects that consist of the filter's mask and whether thefilter is to be inserted into the A-TCAM or the C-TCAM since filters indifferent TCAMs cannot share a mask.The set of created objects is dependent on the insertion order of thefilters and is not necessarily optimal. Therefore, the driver willperiodically ask the library to compute a more optimal set ("hints") bylooking at all the existing objects.When the library asks the driver whether two objects can be aggregatedthe driver only compares the provided masks and ignores the A-TCAM /C-TCAM indication. This is the right thing to do since the goal is tomove as many filters as possible to the A-TCAM. The driver also forbidstwo identical masks from being aggregated since this can only happen ifone was intentionally put in the C-TCAM to avoid a conflict in theA-TCAM.The above can result in the following set of hints:H1: {mask X, A-TCAM} -> H2: {mask Y, A-TCAM} // X is Y + deltaH3: {mask Y, C-TCAM} -> H4: {mask Z, A-TCAM} // Y is Z + deltaAfter getting the hints from the library the driver will start migratingfilters from one region to another while consulting the computed hintsand instructing the device to perform a lookup in both regions duringthe transition.Assuming a filter with mask X is being migrated into the A-TCAM in thenew region, the hints lookup will return H1. Since H2 is the parent ofH1, the library will try to find the object associated with it andcreate it if necessary in which case another hints lookup (recursive)will be performed. This hints lookup for {mask Y, A-TCAM} will eitherreturn H2 or H3 since the driver passes the library an object comparisonfunction that ignores the A-TCAM / C-TCAM indication.This can eventually lead to nested objects which are not supported bythe library [1].Fix by removing the object comparison function from both the driver andthe library as the driver was the only user. That way the lookup willonly return exact matches.I do not have a reliable reproducer that can reproduce the issue in atimely manner, but before the fix the issue would reproduce in severalminutes and with the fix it does not reproduce in over an hour.Note that the current usefulness of the hints is limited because theyinclude the C-TCAM indication and represent aggregation that cannotactually happen. This will be addressed in net-next.[1]WARNING: CPU: 0 PID: 153 at lib/objagg.c:170 objagg_obj_parent_assign+0xb5/0xd0Modules linked in:CPU: 0 PID: 153 Comm: kworker/0:18 Not tainted 6.9.0-rc6-custom-g70fbc2c1c38b #42Hardware name: Mellanox Technologies Ltd.

[0]The repro first creates a listener with SO_REUSEPORT. Then, it createsanother listener on the same port and concurrently closes the firstlistener.The second listen() calls reuseport_add_sock() with the first listener assk2, where sk2->sk_reuseport_cb is not expected to be cleared concurrently,but the close() does clear it by reuseport_detach_sock().The problem is SCTP does not properly synchronise reuseport_alloc(),reuseport_add_sock(), and reuseport_detach_sock().The caller of reuseport_alloc() and reuseport_{add,detach}_sock() mustprovide synchronisation for sockets that are classified into the samereuseport group.Otherwise, such sockets form multiple identical reuseport groups, andall groups except one would be silently dead. 1. Two sockets call listen() concurrently 2. No socket in the same group found in sctp_ep_hashtable[] 3. Two sockets call reuseport_alloc() and form two reuseport groups 4. Only one group hit first in __sctp_rcv_lookup_endpoint() receives incoming packetsAlso, the reported null-ptr-deref could occur.TCP/UDP guarantees that would not happen by holding the hash bucket lock.Let's apply the locking strategy to __sctp_hash_endpoint() and__sctp_unhash_endpoint().[0]:Oops: general protection fault, probably for non-canonical address 0xdffffc0000000002: 0000 [#1] PREEMPT SMP KASAN PTIKASAN: null-ptr-deref in range [0x0000000000000010-0x0000000000000017]CPU: 1 UID: 0 PID: 10230 Comm: syz-executor119 Not tainted 6.10.0-syzkaller-12585-g301927d2d2eb #0Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 06/27/2024RIP: 0010:reuseport_add_sock+0x27e/0x5e0 net/core/sock_reuseport.c:350Code: 00 0f b7 5d 00 bf 01 00 00 00 89 de e8 1b a4 ff f7 83 fb 01 0f 85 a3 01 00 00 e8 6d a0 ff f7 49 8d 7e 12 48 89 f8 48 c1 e8 03 <42> 0f b6 04 28 84 c0 0f 85 4b 02 00 00 41 0f b7 5e 12 49 8d 7e 14RSP: 0018:ffffc9000b947c98 EFLAGS: 00010202RAX: 0000000000000002 RBX: ffff8880252ddf98 RCX: ffff888079478000RDX: 0000000000000000 RSI: 0000000000000001 RDI: 0000000000000012RBP: 0000000000000001 R08: ffffffff8993e18d R09: 1ffffffff1fef385R10: dffffc0000000000 R11: fffffbfff1fef386 R12: ffff8880252ddac0R13: dffffc0000000000 R14: 0000000000000000 R15: 0000000000000000FS: 00007f24e45b96c0(0000) GS:ffff8880b9300000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007ffcced5f7b8 CR3: 00000000241be000 CR4: 00000000003506f0DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400Call Trace: __sctp_hash_endpoint net/sctp/input.c:762 [inline] sctp_hash_endpoint+0x52a/0x600 net/sctp/input.c:790 sctp_listen_start net/sctp/socket.c:8570 [inline] sctp_inet_listen+0x767/0xa20 net/sctp/socket.c:8625 __sys_listen_socket net/socket.c:1883 [inline] __sys_listen+0x1b7/0x230 net/socket.c:1894 __do_sys_listen net/socket.c:1902 [inline] __se_sys_listen net/socket.c:1900 [inline] __x64_sys_listen+0x5a/0x70 net/socket.c:1900 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xf3/0x230 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7fRIP: 0033:0x7f24e46039b9Code: 28 00 00 00 75 05 48 83 c4 28 c3 e8 91 1a 00 00 90 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b0 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007f24e45b9228 EFLAGS: 00000246 ORIG_RAX: 0000000000000032RAX: ffffffffffffffda RBX: 00007f24e468e428 RCX: 00007f24e46039b9RDX: 00007f24e46039b9 RSI: 0000000000000003 RDI: 0000000000000004RBP: 00007f24e468e420 R08: 00007f24e45b96c0 R09: 00007f24e45b96c0R10: 00007f24e45b96c0 R11: 0000000000000246 R12: 00007f24e468e42cR13:---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:x86/mtrr: Check if fixed MTRRs exist before saving themMTRRs have an obsolete fixed variant for fine grained caching controlof the 640K-1MB region that uses separate MSRs. This fixed variant hasa separate capability bit in the MTRR capability MSR.So far all x86 CPUs which support MTRR have this separate bit set, so itwent unnoticed that mtrr_save_state() does not check the capability bitbefore accessing the fixed MTRR MSRs.Though on a CPU that does not support the fixed MTRR capability thisresults in a #GP. The #GP itself is harmless because the RDMSR fault ishandled gracefully, but results in a WARN_ON().Add the missing capability check to prevent this.

CVE-2024-45011 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:char: xillybus: Check USB endpoints when probing deviceEnsure, as the driver probes the device, that all endpoints that thedriver may attempt to access exist and are of the correct type.All XillyUSB devices must have a Bulk IN and Bulk OUT endpoint ataddress 1. This is verified in xillyusb_setup_base_eps().On top of that, a XillyUSB device may have additional Bulk OUTendpoints. The information about these endpoints' addresses is deducedfrom a data structure (the IDT) that the driver fetches from the devicewhile probing it. These endpoints are checked in setup_channels().A XillyUSB device never has more than one IN endpoint, as all datatowards the host is multiplexed in this single Bulk IN endpoint. This iswhy setup_channels() only checks OUT endpoints.

CVE-2024-45025 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fix bitmap corruption on close_range() with CLOSE_RANGE_UNSHAREcopy_fd_bitmaps(new, old, count) is expected to copy the firstcount/BITS_PER_LONG bits from old->full_fds_bits[] and fillthe rest with zeroes. What it does is copying enough words(BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest.That works fine, *if* all bits past the cutoff point areclear. Otherwise we are risking garbage from the last wordwe'd copied.For most of the callers that is true - expand_fdtable() hascount equal to old->max_fds, so there's no open descriptorspast count, let alone fully occupied words in ->open_fds[],which is what bits in ->full_fds_bits[] correspond to.The other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds),which is the smallest multiple of BITS_PER_LONG that covers allopened descriptors below max_fds. In the common case (copying onfork()) max_fds is ~0U, so all opened descriptors will be belowit and we are fine, by the same reasons why the call in expand_fdtable()is safe.Unfortunately, there is a case where max_fds is less than thatand where we might, indeed, end up with junk in ->full_fds_bits[] -close_range(from, to, CLOSE_RANGE_UNSHARE) with * descriptor table being currently shared * 'to' being above the current capacity of descriptor table * 'from' being just under some chunk of opened descriptors.In that case we end up with observably wrong behaviour - e.g. spawna child with CLONE_FILES, get all descriptors in range 0..127 open,then close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) endingup with descriptor #128, despite #64 being observably not open.The minimally invasive fix would be to deal with that in dup_fd().If this proves to add measurable overhead, we can go that way, butlet's try to fix copy_fd_bitmaps() first.* new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).* make copy_fd_bitmaps() take the bitmap size in words, rather thanbits; it's 'count' argument is always a multiple of BITS_PER_LONG,so we are not losing any information, and that way we can use thesame helper for all three bitmaps - compiler will see that countis a multiple of BITS_PER_LONG for the large ones, so it'll generateplain memcpy()+memset().Reproducer added to tools/testing/selftests/core/close_range_test.c

CVE-2024-45029 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:i2c: tegra: Do not mark ACPI devices as irq safeOn ACPI machines, the tegra i2c module encounters an issue due to amutex being called inside a spinlock. This leads to the following bug: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:585 ... Call trace: __might_sleep __mutex_lock_common mutex_lock_nested acpi_subsys_runtime_resume rpm_resume tegra_i2c_xferThe problem arises because during __pm_runtime_resume(), the spinlock&dev->power.lock is acquired before rpm_resume() is called. Later,rpm_resume() invokes acpi_subsys_runtime_resume(), which relies onmutexes, triggering the error.To address this issue, devices on ACPI are now marked as not IRQ-safe,considering the dependency of acpi_subsys_runtime_resume() on mutexes.

CVE-2024-46689 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:soc: qcom: cmd-db: Map shared memory as WC, not WBLinux does not write into cmd-db region. This region of memory is writeprotected by XPU. XPU may sometime falsely detect clean cache evictionas "write" into the write protected region leading to secure interruptwhich causes an endless loop somewhere in Trust Zone.The only reason it is working right now is because Qualcomm Hypervisormaps the same region as Non-Cacheable memory in Stage 2 translationtables. The issue manifests if we want to use another hypervisor (likeXen or KVM), which does not know anything about those specific mappings.Changing the mapping of cmd-db memory from MEMREMAP_WB to MEMREMAP_WT/WCremoves dependency on correct mappings in Stage 2 tables. This patchfixes the issue by updating the mapping to MEMREMAP_WC.I tested this on SA8155P with Xen.

CVE-2024-46695 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:selinux,smack: don't bypass permissions check in inode_setsecctx hookMarek Gresko reports that the root user on an NFS client is able tochange the security labels on files on an NFS filesystem that isexported with root squashing enabled.The end of the kerneldoc comment for __vfs_setxattr_noperm() states: * This function requires the caller to lock the inode's i_mutex before it * is executed. It also assumes that the caller will make the appropriate * permission checks.nfsd_setattr() does do permissions checking via fh_verify() andnfsd_permission(), but those don't do all the same permissions checksthat are done by security_inode_setxattr() and its related LSM hooks do.Since nfsd_setattr() is the only consumer of security_inode_setsecctx(),simplest solution appears to be to replace the call to__vfs_setxattr_noperm() with a call to __vfs_setxattr_locked(). Thisfixes the above issue and has the added benefit of causing nfsd torecall conflicting delegations on a file when a client tries to changeits security label.

Description: In the Linux kernel, the following vulnerability has been resolved:pci/hotplug/pnv_php: Fix hotplug driver crash on PowernvThe hotplug driver for powerpc (pci/hotplug/pnv_php.c) causes a kernelcrash when we try to hot-unplug/disable the PCIe switch/bridge fromthe PHB.The crash occurs because although the MSI data structure has beenreleased during disable/hot-unplug path and it has been assignedwith NULL, still during unregistration the code was again trying toexplicitly disable the MSI which causes the NULL pointer dereference andkernel crash.The patch fixes the check during unregistration path to prevent invokingpci_disable_msi/msix() since its data structure is already freed.

[0]The NULL pointer is sk->sk_user_data, and the offset 8 is of protocolin struct fou.When fou_release() is called due to netns dismantle or explicit tunnelteardown, udp_tunnel_sock_release() sets NULL to sk->sk_user_data.Then, the tunnel socket is destroyed after a single RCU grace period.So, in-flight udp4_gro_receive() could find the socket and execute theFOU GRO handler, where sk->sk_user_data could be NULL.Let's use rcu_dereference_sk_user_data() in fou_from_sock() and add NULLchecks in FOU GRO handlers.[0]:BUG: kernel NULL pointer dereference, address: 0000000000000008 PF: supervisor read access in kernel mode PF: error_code(0x0000) - not-present pagePGD 80000001032f4067 P4D 80000001032f4067 PUD 103240067 PMD 0SMP PTICPU: 0 PID: 0 Comm: swapper/0 Not tainted 5.10.216-204.855.amzn2.x86_64 #1Hardware name: Amazon EC2 c5.large/, BIOS 1.0 10/16/2017RIP: 0010:fou_gro_receive (net/ipv4/fou.c:233) [fou]Code: 41 5f c3 cc cc cc cc e8 e7 2e 69 f4 0f 1f 80 00 00 00 00 0f 1f 44 00 00 49 89 f8 41 54 48 89 f7 48 89 d6 49 8b 80 88 02 00 00 <0f> b6 48 08 0f b7 42 4a 66 25 fd fd 80 cc 02 66 89 42 4a 0f b6 42RSP: 0018:ffffa330c0003d08 EFLAGS: 00010297RAX: 0000000000000000 RBX: ffff93d9e3a6b900 RCX: 0000000000000010RDX: ffff93d9e3a6b900 RSI: ffff93d9e3a6b900 RDI: ffff93dac2e24d08RBP: ffff93d9e3a6b900 R08: ffff93dacbce6400 R09: 0000000000000002R10: 0000000000000000 R11: ffffffffb5f369b0 R12: ffff93dacbce6400R13: ffff93dac2e24d08 R14: 0000000000000000 R15: ffffffffb4edd1c0FS: 0000000000000000(0000) GS:ffff93daee800000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 0000000000000008 CR3: 0000000102140001 CR4: 00000000007706f0DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400PKRU: 55555554Call Trace: ? show_trace_log_lvl (arch/x86/kernel/dumpstack.c:259) ? __die_body.cold (arch/x86/kernel/dumpstack.c:478 arch/x86/kernel/dumpstack.c:420) ? no_context (arch/x86/mm/fault.c:752) ? exc_page_fault (arch/x86/include/asm/irqflags.h:49 arch/x86/include/asm/irqflags.h:89 arch/x86/mm/fault.c:1435 arch/x86/mm/fault.c:1483) ? asm_exc_page_fault (arch/x86/include/asm/idtentry.h:571) ? fou_gro_receive (net/ipv4/fou.c:233) [fou] udp_gro_receive (include/linux/netdevice.h:2552 net/ipv4/udp_offload.c:559) udp4_gro_receive (net/ipv4/udp_offload.c:604) inet_gro_receive (net/ipv4/af_inet.c:1549 (discriminator 7)) dev_gro_receive (net/core/dev.c:6035 (discriminator 4)) napi_gro_receive (net/core/dev.c:6170) ena_clean_rx_irq (drivers/amazon/net/ena/ena_netdev.c:1558) [ena] ena_io_poll (drivers/amazon/net/ena/ena_netdev.c:1742) [ena] napi_poll (net/core/dev.c:6847) net_rx_action (net/core/dev.c:6917) __do_softirq (arch/x86/include/asm/jump_label.h:25 include/linux/jump_label.h:200 include/trace/events/irq.h:142 kernel/softirq.c:299) asm_call_irq_on_stack (arch/x86/entry/entry_64.S:809) do_softirq_own_stack (arch/x86/include/asm/irq_stack.h:27 arch/x86/include/asm/irq_stack.h:77 arch/x86/kernel/irq_64.c:77) irq_exit_rcu (kernel/softirq.c:393 kernel/softirq.c:423 kernel/softirq.c:435) common_interrupt (arch/x86/kernel/irq.c:239) asm_common_interrupt (arch/x86/include/asm/idtentry.h:626)RIP: 0010:acpi_idle_do_entry (arch/x86/include/asm/irqflags.h:49 arch/x86/include/asm/irqflags.h:89 drivers/acpi/processor_idle.c:114 drivers/acpi/processor_idle.c:575)Code: 8b 15 d1 3c c4 02 ed c3 cc cc cc cc 65 48 8b 04 25 40 ef 01 00 48 8b 00 a8 08 75 eb 0f 1f 44 00 00 0f 00 2d d5 09 55 00 fb f4 c3 cc cc cc cc e9 be fc ff ff 66 66 2e 0f 1f 84 00 00 00 00 00RSP: 0018:ffffffffb5603e58 EFLAGS: 00000246RAX: 0000000000004000 RBX: ffff93dac0929c00 RCX: ffff93daee833900RDX: ffff93daee800000 RSI: ffff93d---truncated---

The former one is not astrivial, because between ice_vsi_close() and ice_vsi_rebuild(), a lot ofhardware interaction happens, this can make adding/deleting rings exitwith an error. Luckily, VSI rebuild is pending and can apply newconfiguration for us in a managed fashion.Therefore, add an additional VSI state flag ICE_VSI_REBUILD_PENDING toindicate that ice_x---truncated---

CVE-2024-46828 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:sched: sch_cake: fix bulk flow accounting logic for host fairnessIn sch_cake, we keep track of the count of active bulk flows per host,when running in dst/src host fairness mode, which is used as theround-robin weight when iterating through flows. The count of activebulk flows is updated whenever a flow changes state.This has a peculiar interaction with the hash collision handling: when ahash collision occurs (after the set-associative hashing), the state ofthe hash bucket is simply updated to match the new packet that collided,and if host fairness is enabled, that also means assigning new per-hoststate to the flow. For this reason, the bulk flow counters of thehost(s) assigned to the flow are decremented, before new state isassigned (and the counters, which may not belong to the same hostanymore, are incremented again).Back when this code was introduced, the host fairness mode was alwaysenabled, so the decrement was unconditional. When the configurationflags were introduced the *increment* was made conditional, butthe *decrement* was not. Which of course can lead to a spuriousdecrement (and associated wrap-around to U16_MAX).AFAICT, when host fairness is disabled, the decrement and wrap-aroundhappens as soon as a hash collision occurs (which is not that common initself, due to the set-associative hashing). However, in most cases thisis harmless, as the value is only used when host fairness mode isenabled. So in order to trigger an array overflow, sch_cake has to firstbe configured with host fairness disabled, and while running in thismode, a hash collision has to occur to cause the overflow. Then, theqdisc has to be reconfigured to enable host fairness, which leads to thearray out-of-bounds because the wrapped-around value is retained andused as an array index. It seems that syzbot managed to trigger this,which is quite impressive in its own right.This patch fixes the issue by introducing the same conditional check ondecrement as is used on increment.The original bug predates the upstreaming of cake, but the commit listedin the Fixes tag touched that code, meaning that this patch won't applybefore that.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: clean up our handling of refs == 0 in snapshot deleteIn reada we BUG_ON(refs == 0), which could be unkind since we aren'tholding a lock on the extent leaf and thus could get a transientincorrect answer. In walk_down_proc we also BUG_ON(refs == 0), whichcould happen if we have extent tree corruption. Change that to return-EUCLEAN. In do_walk_down() we catch this case and handle it correctly,however we return -EIO, which -EUCLEAN is a more appropriate error code.Finally in walk_up_proc we have the same BUG_ON(refs == 0), so convertthat to proper error handling. Also adjust the error message so we canactually do something with the information.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: lpfc: Handle mailbox timeouts in lpfc_get_sfp_infoThe MBX_TIMEOUT return code is not handled in lpfc_get_sfp_info and theroutine unconditionally frees submitted mailbox commands regardless ofreturn status. The issue is that for MBX_TIMEOUT cases, when firmwarereturns SFP information at a later time, that same mailbox memory regionreferences previously freed memory in its cmpl routine.Fix by adding checks for the MBX_TIMEOUT return code. During mailboxresource cleanup, check the mbox flag to make sure that the wait did nottimeout. If the MBOX_WAKE flag is not set, then do not free the resourcesbecause it will be freed when firmware completes the mailbox at a latertime in its cmpl routine.Also, increase the timeout from 30 to 60 seconds to accommodate bootscripts requiring longer timeouts.

(For thedetails, please refer https://lore.kernel.org/lkml/87plq9l5d2.ffs@tglx/)The HSW11 requires a period larger than 100 for the INST_RETIRED.ALLevent, but the initial period in the freq mode is 1. The erratum is thesame as the BDM11, which has been supported in the kernel. A minimumperiod of 128 is enforced as well on HSW.HSW143 is regarding that the fixed counter 1 may overcount 32 with theHyper-Threading is enabled. However, based on the test, the hardwarehas more issues than it tells. Besides the fixed counter 1, the message'interrupt took too long' can be observed on any counter which was armedwith a period < 32 and two events expired in the same NMI. A minimumperiod of 32 is enforced for the rest of the events.The recommended workaround code of the HSW143 is not implemented.Because it only addresses the issue for the fixed counter. It bringsextra overhead through extra MSR writing. No related overcounting issuehas been reported so far.

CVE-2024-46859 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:platform/x86: panasonic-laptop: Fix SINF array out of bounds accessesThe panasonic laptop code in various places uses the SINF array with indexvalues of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF arrayis big enough.Not all panasonic laptops have this many SINF array entries, for examplethe Toughbook CF-18 model only has 10 SINF array entries. So it onlysupports the AC+DC brightness entries and mute.Check that the SINF array has a minimum size which covers all AC+DCbrightness entries and refuse to load if the SINF array is smaller.For higher SINF indexes hide the sysfs attributes when the SINF arraydoes not contain an entry for that attribute, avoiding show()/store()accessing the array out of bounds and add bounds checking to the probe()and resume() code accessing these.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: pm80xx: Set phy->enable_completion only when we wait for itpm8001_phy_control() populates the enable_completion pointer with a stackaddress, sends a PHY_LINK_RESET / PHY_HARD_RESET, waits 300 ms, andreturns. The problem arises when a phy control response comes late. After300 ms the pm8001_phy_control() function returns and the passedenable_completion stack address is no longer valid. Late phy controlresponse invokes complete() on a dangling enable_completion pointer whichleads to a kernel crash.

Description: In the Linux kernel, the following vulnerability has been resolved:icmp: change the order of rate limitsICMP messages are ratelimited :After the blamed commits, the two rate limiters are applied in this order:1) host wide ratelimit (icmp_global_allow())2) Per destination ratelimit (inetpeer based)In order to avoid side-channels attacks, we need to applythe per destination check first.This patch makes the following change :1) icmp_global_allow() checks if the host wide limit is reached. But credits are not yet consumed. This is deferred to 3)2) The per destination limit is checked/updated. This might add a new node in inetpeer tree.3) icmp_global_consume() consumes tokens if prior operations succeeded.This means that host wide ratelimit is still effectivein keeping inetpeer tree small even under DDOS.As a bonus, I removed icmp_global.lock as the fast pathcan use a lock-free operation.

CVE-2024-47705 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:block: fix potential invalid pointer dereference in blk_add_partitionThe blk_add_partition() function initially used a single if-condition(IS_ERR(part)) to check for errors when adding a partition. This wasmodified to handle the specific case of -ENXIO separately, allowing thefunction to proceed without logging the error in this case. However,this change unintentionally left a path where md_autodetect_dev()could be called without confirming that part is a valid pointer.This commit separates the error handling logic by splitting theinitial if-condition, improving code readability and handling specificerror scenarios explicitly. The function now distinguishes the generalerror case from -ENXIO without altering the existing behavior ofmd_autodetect_dev() calls.

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: hisilicon/qm - inject error before stopping queueThe master ooo cannot be completely closed when theaccelerator core reports memory error. Therefore, the driverneeds to inject the qm error to close the master ooo. Currently,the qm error is injected after stopping queue, memory may bereleased immediately after stopping queue, causing the device toaccess the released memory. Therefore, error is injected to close masterooo before stopping queue to ensure that the device does not accessthe released memory.

CVE-2024-47736 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:erofs: handle overlapped pclusters out of crafted images properlysyzbot reported a task hang issue due to a deadlock case where it iswaiting for the folio lock of a cached folio that will be used forcache I/Os.After looking into the crafted fuzzed image, I found it's formed withseveral overlapped big pclusters as below: Ext: logical offset | length : physical offset | length 0: 0.. 16384 | 16384 : 151552.. 167936 | 16384 1: 16384.. 32768 | 16384 : 155648.. 172032 | 16384 2: 32768.. 49152 | 16384 : 537223168.. 537239552 | 16384...Here, extent 0/1 are physically overlapped although it's entirely_impossible_ for normal filesystem images generated by mkfs.First, managed folios containing compressed data will be marked asup-to-date and then unlocked immediately (unlike in-place folios) whencompressed I/Os are complete. If physical blocks are not submitted inthe incremental order, there should be separate BIOs to avoid dependencyissues. However, the current code mis-arranges z_erofs_fill_bio_vec()and BIO submission which causes unexpected BIO waits.Second, managed folios will be connected to their own pclusters forefficient inter-queries. However, this is somewhat hard to implementeasily if overlapped big pclusters exist. Again, these only appear infuzzed images so let's simply fall back to temporary short-lived pagesfor correctness.Additionally, it justifies that referenced managed folios cannot betruncated for now and reverts part of commit 2080ca1ed3e4 ("erofs: tidyup `struct z_erofs_bvec`") for simplicity although it shouldn't be anydifference.

CVE-2024-47739 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:padata: use integer wrap around to prevent deadlock on seq_nr overflowWhen submitting more than 2^32 padata objects to padata_do_serial, thecurrent sorting implementation incorrectly sorts padata objects withoverflowed seq_nr, causing them to be placed before existing objects inthe reorder list. This leads to a deadlock in the serialization processas padata_find_next cannot match padata->seq_nr and pd->processedbecause the padata instance with overflowed seq_nr will be selectednext.To fix this, we use an unsigned integer wrap around to correctly sortpadata objects in scenarios with integer overflow.

CVE-2024-47809 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:dlm: fix possible lkb_resource null dereferenceThis patch fixes a possible null pointer dereference when this function iscalled from request_lock() as lkb->lkb_resource is not assigned yet,only after validate_lock_args() by calling attach_lkb(). Another issueis that a resource name could be a non printable bytearray and we cannotassume to be ASCII coded.The log functionality is probably never being hit when DLM is used innormal way and no debug logging is enabled. The null pointer dereferencecan only occur on a new created lkb that does not have the resourceassigned yet, it probably never hits the null pointer dereference but weshould be sure that other changes might not change this behaviour and weactually can hit the mentioned null pointer dereference.In this patch we just drop the printout of the resource name, the lkb idis enough to make a possible connection to a resource name if thisexists.

CVE-2024-49863 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:vhost/scsi: null-ptr-dereference in vhost_scsi_get_req()Since commit 3f8ca2e115e5 ("vhost/scsi: Extract common handling codefrom control queue handler") a null pointer dereference bug can betriggered when guest sends an SCSI AN request.In vhost_scsi_ctl_handle_vq(), `vc.target` is assigned with`&v_req.tmf.lun[1]` within a switch-case block and is then passed tovhost_scsi_get_req() which extracts `vc->req` and `tpg`. However, fora `VIRTIO_SCSI_T_AN_*` request, tpg is not required, so `vc.target` isset to NULL in this branch. Later, in vhost_scsi_get_req(),`vc->target` is dereferenced without being checked, leading to a nullpointer dereference bug. This bug can be triggered from guest.When this bug occurs, the vhost_worker process is killed while holding`vq->mutex` and the corresponding tpg will remain occupiedindefinitely.Below is the KASAN report:Oops: general protection fault, probably for non-canonical address0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN NOPTIKASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]CPU: 1 PID: 840 Comm: poc Not tainted 6.10.0+ #1Hardware name: QEMU Ubuntu 24.04 PC (i440FX + PIIX, 1996), BIOS1.16.3-debian-1.16.3-2 04/01/2014RIP: 0010:vhost_scsi_get_req+0x165/0x3a0Code: 00 fc ff df 48 89 fa 48 c1 ea 03 80 3c 02 00 0f 85 2b 02 00 0048 b8 00 00 00 00 00 fc ff df 4d 8b 65 30 4c 89 e2 48 c1 ea 03 <0f> b604 02 4c 89 e2 83 e2 07 38 d0 7f 08 84 c0 0f 85 be 01 00 00RSP: 0018:ffff888017affb50 EFLAGS: 00010246RAX: dffffc0000000000 RBX: ffff88801b000000 RCX: 0000000000000000RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff888017affcb8RBP: ffff888017affb80 R08: 0000000000000000 R09: 0000000000000000R10: 0000000000000000 R11: 0000000000000000 R12: 0000000000000000R13: ffff888017affc88 R14: ffff888017affd1c R15: ffff888017993000FS: 000055556e076500(0000) GS:ffff88806b100000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00000000200027c0 CR3: 0000000010ed0004 CR4: 0000000000370ef0Call Trace: ? show_regs+0x86/0xa0 ? die_addr+0x4b/0xd0 ? exc_general_protection+0x163/0x260 ? asm_exc_general_protection+0x27/0x30 ? vhost_scsi_get_req+0x165/0x3a0 vhost_scsi_ctl_handle_vq+0x2a4/0xca0 ? __pfx_vhost_scsi_ctl_handle_vq+0x10/0x10 ? __switch_to+0x721/0xeb0 ? __schedule+0xda5/0x5710 ? __kasan_check_write+0x14/0x30 ? _raw_spin_lock+0x82/0xf0 vhost_scsi_ctl_handle_kick+0x52/0x90 vhost_run_work_list+0x134/0x1b0 vhost_task_fn+0x121/0x350... ---[ end trace 0000000000000000 ]---Let's add a check in vhost_scsi_get_req.[whitespace fixes]

But after reallocating and successfully initializingthe path, we don't update *orig_path, in which case the caller gets avalid path but a NULL ppath, and this may cause a NULL pointer dereferenceor a path memory leak. For example:ext4_split_extent path = *ppath = 2000 ext4_find_extent if (depth > path[0].p_maxdepth) kfree(path = 2000); *orig_path = path = NULL; path = kcalloc() = 3000 ext4_split_extent_at(*ppath = NULL) path = *ppath; ex = path[depth].p_ext; // NULL pointer dereference!==================================================================BUG: kernel NULL pointer dereference, address: 0000000000000010CPU: 6 UID: 0 PID: 576 Comm: fsstress Not tainted 6.11.0-rc2-dirty #847RIP: 0010:ext4_split_extent_at+0x6d/0x560Call Trace: ext4_split_extent.isra.0+0xcb/0x1b0 ext4_ext_convert_to_initialized+0x168/0x6c0 ext4_ext_handle_unwritten_extents+0x325/0x4d0 ext4_ext_map_blocks+0x520/0xdb0 ext4_map_blocks+0x2b0/0x690 ext4_iomap_begin+0x20e/0x2c0[...]==================================================================Therefore, *orig_path is updated when the extent lookup succeeds, so thatthe caller can safely use path or *ppath.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amd/display: Add null check for pipe_ctx->plane_state in dcn20_program_pipeThis commit addresses a null pointer dereference issue in the`dcn20_program_pipe` function. The issue could occur when`pipe_ctx->plane_state` is null.The fix adds a check to ensure `pipe_ctx->plane_state` is not nullbefore accessing. This prevents a null pointer dereference.Reported by smatch:drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn20/dcn20_hwseq.c:1925 dcn20_program_pipe() error: we previously assumed 'pipe_ctx->plane_state' could be null (see line 1877)

Description: In the Linux kernel, the following vulnerability has been resolved:net: avoid potential underflow in qdisc_pkt_len_init() with UFOAfter commit 7c6d2ecbda83 ("net: be more gentle about silly gsorequests coming from user") virtio_net_hdr_to_skb() had sanity checkto detect malicious attempts from user space to cook a bad GSO packet.Then commit cf9acc90c80ec ("net: virtio_net_hdr_to_skb: counttransport header in UFO") while fixing one issue, allowed user spaceto cook a GSO packet with the following characteristic :IPv4 SKB_GSO_UDP, gso_size=3, skb->len = 28.When this packet arrives in qdisc_pkt_len_init(), we end upwith hdr_len = 28 (IPv4 header + UDP header), matching skb->lenThen the following sets gso_segs to 0 :gso_segs = DIV_ROUND_UP(skb->len - hdr_len, shinfo->gso_size);Then later we set qdisc_skb_cb(skb)->pkt_len to back to zero :/qdisc_skb_cb(skb)->pkt_len += (gso_segs - 1) * hdr_len;This leads to the following crash in fq_codel [1]qdisc_pkt_len_init() is best effort, we only want an estimationof the bytes sent on the wire, not crashing the kernel.This patch is fixing this particular issue, a following oneadds more sanity checks for another potential bug.[1][ 70.724101] BUG: kernel NULL pointer dereference, address: 0000000000000000[ 70.724561] #PF: supervisor read access in kernel mode[ 70.724561] #PF: error_code(0x0000) - not-present page[ 70.724561] PGD 10ac61067 P4D 10ac61067 PUD 107ee2067 PMD 0[ 70.724561] Oops: Oops: 0000 [#1] SMP NOPTI[ 70.724561] CPU: 11 UID: 0 PID: 2163 Comm: b358537762 Not tainted 6.11.0-virtme #991[ 70.724561] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-debian-1.16.3-2 04/01/2014[ 70.724561] RIP: 0010:fq_codel_enqueue (net/sched/sch_fq_codel.c:120 net/sched/sch_fq_codel.c:168 net/sched/sch_fq_codel.c:230) sch_fq_codel[ 70.724561] Code: 24 08 49 c1 e1 06 44 89 7c 24 18 45 31 ed 45 31 c0 31 ff 89 44 24 14 4c 03 8b 90 01 00 00 eb 04 39 ca 73 37 4d 8b 39 83 c7 01 <49> 8b 17 49 89 11 41 8b 57 28 45 8b 5f 34 49 c7 07 00 00 00 00 49All code======== 0: 24 08 and $0x8,%al 2: 49 c1 e1 06 shl $0x6,%r9 6: 44 89 7c 24 18 mov %r15d,0x18(%rsp) b: 45 31 ed xor %r13d,%r13d e: 45 31 c0 xor %r8d,%r8d 11: 31 ff xor %edi,%edi 13: 89 44 24 14 mov %eax,0x14(%rsp) 17: 4c 03 8b 90 01 00 00 add 0x190(%rbx),%r9 1e: eb 04 jmp 0x24 20: 39 ca cmp %ecx,%edx 22: 73 37 jae 0x5b 24: 4d 8b 39 mov (%r9),%r15 27: 83 c7 01 add $0x1,%edi 2a:* 49 8b 17 mov (%r15),%rdx <-- trapping instruction 2d: 49 89 11 mov %rdx,(%r9) 30: 41 8b 57 28 mov 0x28(%r15),%edx 34: 45 8b 5f 34 mov 0x34(%r15),%r11d 38: 49 c7 07 00 00 00 00 movq $0x0,(%r15) 3f: 49 rex.WBCode starting with the faulting instruction=========================================== 0: 49 8b 17 mov (%r15),%rdx 3: 49 89 11 mov %rdx,(%r9) 6: 41 8b 57 28 mov 0x28(%r15),%edx a: 45 8b 5f 34 mov 0x34(%r15),%r11d e: 49 c7 07 00 00 00 00 movq $0x0,(%r15) 15: 49 rex.WB[ 70.724561] RSP: 0018:ffff95ae85e6fb90 EFLAGS: 00000202[ 70.724561] RAX: 0000000002000000 RBX: ffff95ae841de000 RCX: 0000000000000000[ 70.724561] RDX: 0000000000000000 RSI: 0000000000000001 RDI: 0000000000000001[ 70.724561] RBP: ffff95ae85e6fbf8 R08: 0000000000000000 R09: ffff95b710a30000[ 70.724561] R10: 0000000000000000 R11: bdf289445ce31881 R12: ffff95ae85e6fc58[ 70.724561] R13: 0000000000000000 R14: 0000000000000040 R15: 0000000000000000[ 70.724561] FS: 000000002c5c1380(0000) GS:ffff95bd7fcc0000(0000) knlGS:0000000000000000[ 70.724561] CS: 0010 DS: 0000 ES: 0000 C---truncated---

Additionally, use journal instead ofosb->journal directly to simplify the code.

The problematic function is ocfs2_reflink_xattr_inline(). By thetime this function is called the reflink tree is already recreated at thedestination inode from the source inode. At this point, this functionreserves space for inline xattrs at the destination inode without evenchecking if there is space at the root metadata block. It simply reducesthe l_count from 243 to 227 thereby making space of 256 bytes for inlinexattr whereas the inode already has extents beyond this index (in thiscase up to 230), thereby causing corruption.The fix for this is to reserve space for inline metadata at the destinationinode before the reflink tree gets recreated. The customer has verified thefix.

CVE-2024-49983 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: drop ppath from ext4_ext_replay_update_ex() to avoid double-freeWhen calling ext4_force_split_extent_at() in ext4_ext_replay_update_ex(),the 'ppath' is updated but it is the 'path' that is freed, thus potentiallytriggering a double-free in the following process:ext4_ext_replay_update_ex ppath = path ext4_force_split_extent_at(&ppath) ext4_split_extent_at ext4_ext_insert_extent ext4_ext_create_new_leaf ext4_ext_grow_indepth ext4_find_extent if (depth > path[0].p_maxdepth) kfree(path) ---> path First freed *orig_path = path = NULL ---> null ppath kfree(path) ---> path double-free !!!So drop the unnecessary ppath and use path directly to avoid this problem.And use ext4_find_extent() directly to update path, avoiding unnecessarymemory allocation and freeing. Also, propagate the error returned byext4_find_extent() instead of using strange error codes.

CVE-2024-49985 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:i2c: stm32f7: Do not prepare/unprepare clock during runtime suspend/resumeIn case there is any sort of clock controller attached to this I2C buscontroller, for example Versaclock or even an AIC32x4 I2C codec, thenan I2C transfer triggered from the clock controller clk_ops .preparecallback may trigger a deadlock on drivers/clk/clk.c prepare_lock mutex.This is because the clock controller first grabs the prepare_lock mutexand then performs the prepare operation, including its I2C access. TheI2C access resumes this I2C bus controller via .runtime_resume callback,which calls clk_prepare_enable(), which attempts to grab the prepare_lockmutex again and deadlocks.Since the clock are already prepared since probe() and unprepared inremove(), use simple clk_enable()/clk_disable() calls to enable anddisable the clock on runtime suspend and resume, to avoid hitting theprepare_lock mutex.

Description: In the Linux kernel, the following vulnerability has been resolved:cifs: Fix buffer overflow when parsing NFS reparse pointsReparseDataLength is sum of the InodeType size and DataBuffer size.So to get DataBuffer size it is needed to subtract InodeType's size fromReparseDataLength.Function cifs_strndup_from_utf16() is currentlly accessing buf->DataBufferat position after the end of the buffer because it does not subtractInodeType size from the length. Fix this problem and correctly subtractvariable len.Member InodeType is present only when reparse buffer is large enough. Checkfor ReparseDataLength before accessing InodeType to prevent another invalidmemory access.Major and minor rdev values are present also only when reparse buffer islarge enough. Check for reparse buffer size before calling reparse_mkdev().

CVE-2024-50001 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5: Fix error path in multi-packet WQE transmitRemove the erroneous unmap in case no DMA mapping was establishedThe multi-packet WQE transmit code attempts to obtain a DMA mapping forthe skb. This could fail, e.g. under memory pressure, when the IOMMUdriver just can't allocate more memory for page tables. While the codetries to handle this in the path below the err_unmap label it erroneouslyunmaps one entry from the sq's FIFO list of active mappings. Since thecurrent map attempt failed this unmap is removing some random DMA mappingthat might still be required. If the PCI function now presents that IOVA,the IOMMU may assumes a rogue DMA access and e.g. on s390 puts the PCIfunction in error state.The erroneous behavior was seen in a stress-test environment that createdmemory pressure.

CVE-2024-50002 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:static_call: Handle module init failure correctly in static_call_del_module()Module insertion invokes static_call_add_module() to initialize the staticcalls in a module. static_call_add_module() invokes __static_call_init(),which allocates a struct static_call_mod to either encapsulate the built-instatic call sites of the associated key into it so further modules can beadded or to append the module to the module chain.If that allocation fails the function returns with an error code and themodule core invokes static_call_del_module() to clean up eventually addedstatic_call_mod entries.This works correctly, when all keys used by the module were converted overto a module chain before the failure. If not then static_call_del_module()causes a #GP as it blindly assumes that key::mods points to a valid structstatic_call_mod.The problem is that key::mods is not a individual struct member of structstatic_call_key, it's part of a union to save space: union { /* bit 0: 0 = mods, 1 = sites */ unsigned long type; struct static_call_mod *mods; struct static_call_site *sites; };key::sites is a pointer to the list of built-in usage sites of the staticcall. The type of the pointer is differentiated by bit 0. A mods pointerhas the bit clear, the sites pointer has the bit set.As static_call_del_module() blidly assumes that the pointer is a validstatic_call_mod type, it fails to check for this failure case anddereferences the pointer to the list of built-in call sites, which isobviously bogus.Cure it by checking whether the key has a sites or a mods pointer.If it's a sites pointer then the key is not to be touched. As the sites arewalked in the same order as in __static_call_init() the site walk can beterminated because all subsequent sites have not been touched by the initcode due to the error exit.If it was converted before the allocation fail, then the inner loop whichsearches for a module match will find nothing.A fail in the second allocation in __static_call_init() is harmless anddoes not require special treatment. The first allocation succeeded andconverted the key to a module chain. That first entry has mod::mod == NULLand mod::next == NULL, so the inner loop of static_call_del_module() willneither find a module match nor a module chain. The next site in the walkwas either already converted, but can't match the module, or it will exitthe outer loop because it has a static_call_site pointer and not astatic_call_mod pointer.

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: dax: fix overflowing extents beyond inode size when partially writingThe dax_iomap_rw() does two things in each iteration: map written blocksand copy user data to blocks. If the process is killed by user(See signalhandling in dax_iomap_iter()), the copied data will be returned and addedon inode size, which means that the length of written extents may exceedthe inode size, then fsck will fail. An example is given as:dd if=/dev/urandom of=file bs=4M count=1 dax_iomap_rw iomap_iter // round 1 ext4_iomap_begin ext4_iomap_alloc // allocate 0~2M extents(written flag) dax_iomap_iter // copy 2M data iomap_iter // round 2 iomap_iter_advance iter->pos += iter->processed // iter->pos = 2M ext4_iomap_begin ext4_iomap_alloc // allocate 2~4M extents(written flag) dax_iomap_iter fatal_signal_pending done = iter->pos - iocb->ki_pos // done = 2M ext4_handle_inode_extension ext4_update_inode_size // inode size = 2Mfsck reports: Inode 13, i_size is 2097152, should be 4194304.

IPSEC maintainers might take a look and see how to address this.2) There is also discussion about removing this count of dst, which might happen in future kernels.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: xtables: avoid NFPROTO_UNSPEC where neededsyzbot managed to call xt_cluster match via ebtables: WARNING: CPU: 0 PID: 11 at net/netfilter/xt_cluster.c:72 xt_cluster_mt+0x196/0x780 [..] ebt_do_table+0x174b/0x2a40Module registers to NFPROTO_UNSPEC, but it assumes ipv4/ipv6 packetprocessing. As this is only useful to restrict locally terminatingTCP/UDP traffic, register this for ipv4 and ipv6 family only.Pablo points out that this is a general issue, direct users of theset/getsockopt interface can call into targets/matches that were onlyintended for use with ip(6)tables.Check all UNSPEC matches and targets for similar issues:- matches and targets are fine except if they assume skb_network_header() is valid -- this is only true when called from inet layer: ip(6) stack pulls the ip/ipv6 header into linear data area.- targets that return XT_CONTINUE or other xtables verdicts must be restricted too, they are incompatbile with the ebtables traverser, e.g. EBT_CONTINUE is a completely different value than XT_CONTINUE.Most matches/targets are changed to register for NFPROTO_IPV4/IPV6, asthey are provided for use by ip(6)tables.The MARK target is also used by arptables, so register for NFPROTO_ARP too.While at it, bail out if connbytes fails to enable the correspondingconntrack family.This change passes the selftests in iptables.git.

CVE-2024-50041 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:i40e: Fix macvlan leak by synchronizing access to mac_filter_hashThis patch addresses a macvlan leak issue in the i40e driver caused byconcurrent access to vsi->mac_filter_hash. The leak occurs when multiplethreads attempt to modify the mac_filter_hash simultaneously, leading toinconsistent state and potential memory leaks.To fix this, we now wrap the calls to i40e_del_mac_filter() and zeroingvf->default_lan_addr.addr with spin_lock/unlock_bh(&vsi->mac_filter_hash_lock),ensuring atomic operations and preventing concurrent access.Additionally, we add lockdep_assert_held(&vsi->mac_filter_hash_lock) ini40e_add_mac_filter() to help catch similar issues in the future.Reproduction steps:1. Spawn VFs and configure port vlan on them.2. Trigger concurrent macvlan operations (e.g., adding and deleting portvlan and/or mac filters).3. Observe the potential memory leak and inconsistent state in the mac_filter_hash.This synchronization ensures the integrity of the mac_filter_hash and preventsthe described leak.

CVE-2024-50045 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: br_netfilter: fix panic with metadata_dst skbFix a kernel panic in the br_netfilter module when sending untaggedtraffic via a VxLAN device.This happens during the check for fragmentation in br_nf_dev_queue_xmit.It is dependent on:1) the br_netfilter module being loaded;2) net.bridge.bridge-nf-call-iptables set to 1;3) a bridge with a VxLAN (single-vxlan-device) netdevice as a bridge port;4) untagged frames with size higher than the VxLAN MTU forwarded/floodedWhen forwarding the untagged packet to the VxLAN bridge port, beforethe netfilter hooks are called, br_handle_egress_vlan_tunnel is called andchanges the skb_dst to the tunnel dst. The tunnel_dst is a metadata typeof dst, i.e., skb_valid_dst(skb) is false, and metadata->dst.dev is NULL.Then in the br_netfilter hooks, in br_nf_dev_queue_xmit, there's a checkfor frames that needs to be fragmented: frames with higher MTU than theVxLAN device end up calling br_nf_ip_fragment, which in turns callip_skb_dst_mtu.The ip_dst_mtu tries to use the skb_dst(skb) as if it was a valid dstwith valid dst->dev, thus the crash.This case was never supported in the first place, so drop the packetinstead.PING 10.0.0.2 (10.0.0.2) from 0.0.0.0 h1-eth0: 2000(2028) bytes of data.[ 176.291791] Unable to handle kernel NULL pointer dereference atvirtual address 0000000000000110[ 176.292101] Mem abort info:[ 176.292184] ESR = 0x0000000096000004[ 176.292322] EC = 0x25: DABT (current EL), IL = 32 bits[ 176.292530] SET = 0, FnV = 0[ 176.292709] EA = 0, S1PTW = 0[ 176.292862] FSC = 0x04: level 0 translation fault[ 176.293013] Data abort info:[ 176.293104] ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000[ 176.293488] CM = 0, WnR = 0, TnD = 0, TagAccess = 0[ 176.293787] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0[ 176.293995] user pgtable: 4k pages, 48-bit VAs, pgdp=0000000043ef5000[ 176.294166] [0000000000000110] pgd=0000000000000000,p4d=0000000000000000[ 176.294827] Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP[ 176.295252] Modules linked in: vxlan ip6_udp_tunnel udp_tunnel vethbr_netfilter bridge stp llc ipv6 crct10dif_ce[ 176.295923] CPU: 0 PID: 188 Comm: ping Not tainted6.8.0-rc3-g5b3fbd61b9d1 #2[ 176.296314] Hardware name: linux,dummy-virt (DT)[ 176.296535] pstate: 80000005 (Nzcv daif -PAN -UAO -TCO -DIT -SSBSBTYPE=--)[ 176.296808] pc : br_nf_dev_queue_xmit+0x390/0x4ec [br_netfilter][ 176.297382] lr : br_nf_dev_queue_xmit+0x2ac/0x4ec [br_netfilter][ 176.297636] sp : ffff800080003630[ 176.297743] x29: ffff800080003630 x28: 0000000000000008 x27:ffff6828c49ad9f8[ 176.298093] x26: ffff6828c49ad000 x25: 0000000000000000 x24:00000000000003e8[ 176.298430] x23: 0000000000000000 x22: ffff6828c4960b40 x21:ffff6828c3b16d28[ 176.298652] x20: ffff6828c3167048 x19: ffff6828c3b16d00 x18:0000000000000014[ 176.298926] x17: ffffb0476322f000 x16: ffffb7e164023730 x15:0000000095744632[ 176.299296] x14: ffff6828c3f1c880 x13: 0000000000000002 x12:ffffb7e137926a70[ 176.299574] x11: 0000000000000001 x10: ffff6828c3f1c898 x9 :0000000000000000[ 176.300049] x8 : ffff6828c49bf070 x7 : 0008460f18d5f20e x6 :f20e0100bebafeca[ 176.300302] x5 : ffff6828c7f918fe x4 : ffff6828c49bf070 x3 :0000000000000000[ 176.300586] x2 : 0000000000000000 x1 : ffff6828c3c7ad00 x0 :ffff6828c7f918f0[ 176.300889] Call trace:[ 176.301123] br_nf_dev_queue_xmit+0x390/0x4ec [br_netfilter][ 176.301411] br_nf_post_routing+0x2a8/0x3e4 [br_netfilter][ 176.301703] nf_hook_slow+0x48/0x124[ 176.302060] br_forward_finish+0xc8/0xe8 [bridge][ 176.302371] br_nf_hook_thresh+0x124/0x134 [br_netfilter][ 176.302605] br_nf_forward_finish+0x118/0x22c [br_netfilter][ 176.302824] br_nf_forward_ip.part.0+0x264/0x290 [br_netfilter][ 176.303136] br_nf_forward+0x2b8/0x4e0 [br_netfilter][ 176.303359] nf_hook_slow+0x48/0x124[ 176.303---truncated---

CVE-2024-50058 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:serial: protect uart_port_dtr_rts() in uart_shutdown() tooCommit af224ca2df29 (serial: core: Prevent unsafe uart port access, part3) added few uport == NULL checks. It added one to uart_shutdown(), sothe commit assumes, uport can be NULL in there. But right after thatprotection, there is an unprotected "uart_port_dtr_rts(uport, false);"call. That is invoked only if HUPCL is set, so I assume that is thereason why we do not see lots of these reports.Or it cannot be NULL at this point at all for some reason :P.Until the above is investigated, stay on the safe side and move thisdereference to the if too.I got this inconsistency from Coverity under CID 1585130. Thanks.

CVE-2024-50061 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:i3c: master: cdns: Fix use after free vulnerability in cdns_i3c_master Driver Due to Race ConditionIn the cdns_i3c_master_probe function, &master->hj_work is bound withcdns_i3c_master_hj. And cdns_i3c_master_interrupt can callcnds_i3c_master_demux_ibis function to start the work.If we remove the module which will call cdns_i3c_master_remove tomake cleanup, it will free master->base through i3c_master_unregisterwhile the work mentioned above will be used. The sequence of operationsthat may lead to a UAF bug is as follows:CPU0 CPU1 | cdns_i3c_master_hjcdns_i3c_master_remove |i3c_master_unregister(&master->base) |device_unregister(&master->dev) |device_release |//free master->base | | i3c_master_do_daa(&master->base) | //use master->baseFix it by ensuring that the work is canceled before proceeding withthe cleanup in cdns_i3c_master_remove.

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/rtrs-srv: Avoid null pointer deref during path establishmentFor RTRS path establishment, RTRS client initiates and completes con_numof connections. After establishing all its connections, the informationis exchanged between the client and server through the info_req message.During this exchange, it is essential that all connections have beenestablished, and the state of the RTRS srv path is CONNECTED.So add these sanity checks, to make sure we detect and abort process inerror scenarios to avoid null pointer deref.

Description: In the Linux kernel, the following vulnerability has been resolved:parport: Proper fix for array out-of-bounds accessThe recent fix for array out-of-bounds accesses replaced sprintf()calls blindly with snprintf(). However, since snprintf() returns thewould-be-printed size, not the actually output size, the lengthcalculation can still go over the given limit.Use scnprintf() instead of snprintf(), which returns the actuallyoutput letters, for addressing the potential out-of-bounds accessproperly.

Description: In the Linux kernel, the following vulnerability has been resolved:nouveau/dmem: Fix vulnerability in migrate_to_ram upon copy errorThe `nouveau_dmem_copy_one` function ensures that the copy push command issent to the device firmware but does not track whether it was executedsuccessfully.In the case of a copy error (e.g., firmware or hardware failure), thecopy push command will be sent via the firmware channel, and`nouveau_dmem_copy_one` will likely report success, leading to the`migrate_to_ram` function returning a dirty HIGH_USER page to the user.This can result in a security vulnerability, as a HIGH_USER page that maycontain sensitive or corrupted data could be returned to the user.To prevent this vulnerability, we allocate a zero page. Thus, in case ofan error, a non-dirty (zero) page will be returned to the user.

CVE-2024-50099 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:arm64: probes: Remove broken LDR (literal) uprobe supportThe simulate_ldr_literal() and simulate_ldrsw_literal() functions areunsafe to use for uprobes. Both functions were originally written foruse with kprobes, and access memory with plain C accesses. When uprobeswas added, these were reused unmodified even though they cannot safelyaccess user memory.There are three key problems:1) The plain C accesses do not have corresponding extable entries, and thus if they encounter a fault the kernel will treat these as unintentional accesses to user memory, resulting in a BUG() which will kill the kernel thread, and likely lead to further issues (e.g. lockup or panic()).2) The plain C accesses are subject to HW PAN and SW PAN, and so when either is in use, any attempt to simulate an access to user memory will fault. Thus neither simulate_ldr_literal() nor simulate_ldrsw_literal() can do anything useful when simulating a user instruction on any system with HW PAN or SW PAN.3) The plain C accesses are privileged, as they run in kernel context, and in practice can access a small range of kernel virtual addresses. The instructions they simulate have a range of +/-1MiB, and since the simulated instructions must itself be a user instructions in the TTBR0 address range, these can address the final 1MiB of the TTBR1 acddress range by wrapping downwards from an address in the first 1MiB of the TTBR0 address range. In contemporary kernels the last 8MiB of TTBR1 address range is reserved, and accesses to this will always fault, meaning this is no worse than (1). Historically, it was theoretically possible for the linear map or vmemmap to spill into the final 8MiB of the TTBR1 address range, but in practice this is extremely unlikely to occur as this would require either: * Having enough physical memory to fill the entire linear map all the way to the final 1MiB of the TTBR1 address range. * Getting unlucky with KASLR randomization of the linear map such that the populated region happens to overlap with the last 1MiB of the TTBR address range. ... and in either case if we were to spill into the final page there would be larger problems as the final page would alias with error pointers.Practically speaking, (1) and (2) are the big issues. Given there havebeen no reports of problems since the broken code was introduced, itappears that no-one is relying on probing these instructions withuprobes.Avoid these issues by not allowing uprobes on LDR (literal) and LDRSW(literal), limiting the use of simulate_ldr_literal() andsimulate_ldrsw_literal() to kprobes. Attempts to place uprobes on LDR(literal) and LDRSW (literal) will be rejected asarm_probe_decode_insn() will return INSN_REJECTED. In future we canconsider introducing working uprobes support for these instructions, butthis will require more significant work.

Description: In the Linux kernel, the following vulnerability has been resolved:nfsd: fix race between laundromat and free_stateidThere is a race between laundromat handling of revoked delegationsand a client sending free_stateid operation. Laundromat threadfinds that delegation has expired and needs to be revoked so itmarks the delegation stid revoked and it puts it on a reaper listbut then it unlock the state lock and the actual delegation revocationhappens without the lock. Once the stid is marked revoked a racingfree_stateid processing thread does the following (1) it callslist_del_init() which removes it from the reaper list and (2) freesthe delegation stid structure. The laundromat thread ends up notcalling the revoke_delegation() function for this particular delegationbut that means it will no release the lock lease that exists onthe file.Now, a new open for this file comes in and ends up finding thatlease list isn't empty and calls nfsd_breaker_owns_lease() which endsup trying to derefence a freed delegation stateid.

Then, coordinating whether the stid has been puton the cl_revoked list or we are processing FREE_STATEID and need tomake sure to remove it from the list, each check that state and actaccordingly. If laundromat has added to the cl_revoke list beforethe arrival of FREE_STATEID, then nfsd4_free_stateid() knows to removeit from the list. If nfsd4_free_stateid() finds that operations arrivedbefore laundromat has placed it on cl_revoke list, it marks the statefreed and then laundromat will no longer add it to the list.Also, for nfsd4_delegreturn() when looking for the specified stid,we need to access stid that are marked removed or freeable, it meansthe laundromat has started processing it but hasn't finished and thisdelegreturn needs to return nfserr_deleg_revoked and notnfserr_bad_stateid. The latter will not trigger a FREE_STATEID and thelack of it will leave this stid on the cl_revoked list indefinitely.

CVE-2024-50182 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:secretmem: disable memfd_secret() if arch cannot set direct mapReturn -ENOSYS from memfd_secret() syscall if !can_set_direct_map(). Thisis the case for example on some arm64 configurations, where marking 4kPTEs in the direct map not present can only be done if the direct map isset up at 4k granularity in the first place (as ARM's break-before-makesemantics do not easily allow breaking apart large/gigantic pages).More precisely, on arm64 systems with !can_set_direct_map(),set_direct_map_invalid_noflush() is a no-op, however it returns success(0) instead of an error. This means that memfd_secret will seemingly"work" (e.g. syscall succeeds, you can mmap the fd and fault in pages),but it does not actually achieve its goal of removing its memory from thedirect map.Note that with this patch, memfd_secret() will start erroring on systemswhere can_set_direct_map() returns false (arm64 withCONFIG_RODATA_FULL_DEFAULT_ENABLED=n, CONFIG_DEBUG_PAGEALLOC=n andCONFIG_KFENCE=n), but that still seems better than the current silentfailure. Since CONFIG_RODATA_FULL_DEFAULT_ENABLED defaults to 'y', mostarm64 systems actually have a working memfd_secret() and aren't beaffected.From going through the iterations of the original memfd_secret patchseries, it seems that disabling the syscall in these scenarios was theintended behavior [1] (preferred over havingset_direct_map_invalid_noflush return an error as that would result inSIGBUSes at page-fault time), however the check for it got dropped betweenv16 [2] and v17 [3], when secretmem moved away from CMA allocations.[1]: https://lore.kernel.org/lkml/20201124164930.GK8537@kernel.org/[2]: https://lore.kernel.org/lkml/20210121122723.3446-11-rppt@kernel.org/#t[3]: https://lore.kernel.org/lkml/20201125092208.12544-10-rppt@kernel.org/

CVE-2024-50186 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: explicitly clear the sk pointer, when pf->create failsWe have recently noticed the exact same KASAN splat as in commit6cd4a78d962b ("net: do not leave a dangling sk pointer, when socketcreation fails"). The problem is that commit did not fully address theproblem, as some pf->create implementations do not use sk_common_releasein their error paths.For example, we can use the same reproducer as in the above commit, butchanging ping to arping. arping uses AF_PACKET socket and if packet_createfails, it will just sk_free the allocated sk object.While we could chase all the pf->create implementations and make sure theyNULL the freed sk object on error from the socket, we can't guaranteefuture protocols will not make the same mistake.So it is easier to just explicitly NULL the sk pointer upon return frompf->create in __sock_create. We do know that pf->create always releases theallocated sk object on error, so if the pointer is not NULL, it isdefinitely dangling.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/vc4: Stop the active perfmon before being destroyedUpon closing the file descriptor, the active performance monitor is notstopped. Although all perfmons are destroyed in `vc4_perfmon_close_file()`,the active performance monitor's pointer (`vc4->active_perfmon`) is stillretained.If we open a new file descriptor and submit a few jobs with performancemonitors, the driver will attempt to stop the active performance monitorusing the stale pointer in `vc4->active_perfmon`. However, this pointeris no longer valid because the previous process has already terminated,and all performance monitors associated with it have been destroyed andfreed.To fix this, when the active performance monitor belongs to a givenprocess, explicitly stop it before destroying and freeing it.

CVE-2024-50195 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:posix-clock: Fix missing timespec64 check in pc_clock_settime()As Andrew pointed out, it will make sense that the PTP corechecked timespec64 struct's tv_sec and tv_nsec range before callingptp->info->settime64().As the man manual of clock_settime() said, if tp.tv_sec is negative ortp.tv_nsec is outside the range [0..999,999,999], it should return EINVAL,which include dynamic clocks which handles PTP clock, and the condition isconsistent with timespec64_valid(). As Thomas suggested, timespec64_valid()only check the timespec is valid, but not ensure that the time isin a valid range, so check it ahead using timespec64_valid_strict()in pc_clock_settime() and return -EINVAL if not valid.There are some drivers that use tp->tv_sec and tp->tv_nsec directly towrite registers without validity checks and assume that the higher layerhas checked it, which is dangerous and will benefit from this, such ashclge_ptp_settime(), igb_ptp_settime_i210(), _rcar_gen4_ptp_settime(),and some drivers can remove the checks of itself.

CVE-2024-50196 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:pinctrl: ocelot: fix system hang on level based interruptsThe current implementation only calls chained_irq_enter() andchained_irq_exit() if it detects pending interrupts.```for (i = 0; i < info->stride; i++) { uregmap_read(info->map, id_reg + 4 * i, ®); if (!reg) continue; chained_irq_enter(parent_chip, desc);```However, in case of GPIO pin configured in level mode and the parentcontroller configured in edge mode, GPIO interrupt might be lowered by thehardware. In the result, if the interrupt is short enough, the parentinterrupt is still pending while the GPIO interrupt is cleared;chained_irq_enter() never gets called and the system hangs trying toservice the parent interrupt.Moving chained_irq_enter() and chained_irq_exit() outside the for loopensures that they are called even when GPIO interrupt is lowered by thehardware.The similar code with chained_irq_enter() / chained_irq_exit() functionswrapping interrupt checking loop may be found in many other drivers:```grep -r -A 10 chained_irq_enter drivers/pinctrl```

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: propagate directory read errors from nilfs_find_entry()Syzbot reported that a task hang occurs in vcs_open() during a fuzzingtest for nilfs2.The root cause of this problem is that in nilfs_find_entry(), whichsearches for directory entries, ignores errors when loading a directorypage/folio via nilfs_get_folio() fails.If the filesystem images is corrupted, and the i_size of the directoryinode is large, and the directory page/folio is successfully read butfails the sanity check, for example when it is zero-filled,nilfs_check_folio() may continue to spit out error messages in bursts.Fix this issue by propagating the error to the callers when loading apage/folio fails in nilfs_find_entry().The current interface of nilfs_find_entry() and its callers is outdatedand cannot propagate error codes such as -EIO and -ENOMEM returned vianilfs_find_entry(), so fix it together.

CVE-2024-50271 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:signal: restore the override_rlimit logicPrior to commit d64696905554 ("Reimplement RLIMIT_SIGPENDING on top ofucounts") UCOUNT_RLIMIT_SIGPENDING rlimit was not enforced for a class ofsignals. However now it's enforced unconditionally, even ifoverride_rlimit is set. This behavior change caused production issues. For example, if the limit is reached and a process receives a SIGSEGVsignal, sigqueue_alloc fails to allocate the necessary resources for thesignal delivery, preventing the signal from being delivered with siginfo. This prevents the process from correctly identifying the fault address andhandling the error. From the user-space perspective, applications areunaware that the limit has been reached and that the siginfo iseffectively 'corrupted'. This can lead to unpredictable behavior andcrashes, as we observed with java applications.Fix this by passing override_rlimit into inc_rlimit_get_ucounts() and skipthe comparison to max there if override_rlimit is set. This effectivelyrestores the old behavior.

CVE-2024-50273 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: reinitialize delayed ref list after deleting it from the listAt insert_delayed_ref() if we need to update the action of an existingref to BTRFS_DROP_DELAYED_REF, we delete the ref from its ref head'sref_add_list using list_del(), which leaves the ref's add_list membernot reinitialized, as list_del() sets the next and prev members of thelist to LIST_POISON1 and LIST_POISON2, respectively.If later we end up calling drop_delayed_ref() against the ref, which canhappen during merging or when destroying delayed refs due to a transactionabort, we can trigger a crash since at drop_delayed_ref() we calllist_empty() against the ref's add_list, which returns false sincethe list was not reinitialized after the list_del() and as a consequencewe call list_del() again at drop_delayed_ref(). This results in aninvalid list access since the next and prev members are set to poisonpointers, resulting in a splat if CONFIG_LIST_HARDENED andCONFIG_DEBUG_LIST are set or invalid poison pointer dereferencesotherwise.So fix this by deleting from the list with list_del_init() instead.

With a limit of 1000 scanresults, a frame size upper bound of 4096 (really it'smore like ~2300) and a TBTT entry size of at least 11,we get an upper bound for the number of ~372k, well inthe bounds of a u32.

CVE-2024-53058 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: stmmac: TSO: Fix unbalanced DMA map/unmap for non-paged SKB dataIn case the non-paged data of a SKB carries protocol header and protocolpayload to be transmitted on a certain platform that the DMA AXI addresswidth is configured to 40-bit/48-bit, or the size of the non-paged datais bigger than TSO_MAX_BUFF_SIZE on a certain platform that the DMA AXIaddress width is configured to 32-bit, then this SKB requires at leasttwo DMA transmit descriptors to serve it.For example, three descriptors are allocated to split one DMA buffermapped from one piece of non-paged data: dma_desc[N + 0], dma_desc[N + 1], dma_desc[N + 2].Then three elements of tx_q->tx_skbuff_dma[] will be allocated to holdextra information to be reused in stmmac_tx_clean(): tx_q->tx_skbuff_dma[N + 0], tx_q->tx_skbuff_dma[N + 1], tx_q->tx_skbuff_dma[N + 2].Now we focus on tx_q->tx_skbuff_dma[entry].buf, which is the DMA bufferaddress returned by DMA mapping call. stmmac_tx_clean() will try tounmap the DMA buffer _ONLY_IF_ tx_q->tx_skbuff_dma[entry].bufis a valid buffer address.The expected behavior that saves DMA buffer address of this non-pageddata to tx_q->tx_skbuff_dma[entry].buf is: tx_q->tx_skbuff_dma[N + 0].buf = NULL; tx_q->tx_skbuff_dma[N + 1].buf = NULL; tx_q->tx_skbuff_dma[N + 2].buf = dma_map_single();Unfortunately, the current code misbehaves like this: tx_q->tx_skbuff_dma[N + 0].buf = dma_map_single(); tx_q->tx_skbuff_dma[N + 1].buf = NULL; tx_q->tx_skbuff_dma[N + 2].buf = NULL;On the stmmac_tx_clean() side, when dma_desc[N + 0] is closed by theDMA engine, tx_q->tx_skbuff_dma[N + 0].buf is a valid buffer addressobviously, then the DMA buffer will be unmapped immediately.There may be a rare case that the DMA engine does not finish thepending dma_desc[N + 1], dma_desc[N + 2] yet. Now things will gohorribly wrong, DMA is going to access a unmapped/unreferenced memoryregion, corrupted data will be transmited or iommu fault will betriggered :(In contrast, the for-loop that maps SKB fragments behaves perfectlyas expected, and that is how the driver should do for both non-pageddata and paged frags actually.This patch corrects DMA map/unmap sequences by fixing the array indexfor tx_q->tx_skbuff_dma[entry].buf when assigning DMA buffer address.Tested and verified on DWXGMAC CORE 3.20a

Description: In the Linux kernel, the following vulnerability has been resolved:afs: Fix lock recursionafs_wake_up_async_call() can incur lock recursion. The problem is that itis called from AF_RXRPC whilst holding the ->notify_lock, but it tries totake a ref on the afs_call struct in order to pass it to a work queue - butif the afs_call is already queued, we then have an extraneous ref that mustbe put... calling afs_put_call() may call back down into AF_RXRPC throughrxrpc_kernel_shutdown_call(), however, which might try taking the->notify_lock again.This case isn't very common, however, so defer it to a workqueue. The oopslooks something like: BUG: spinlock recursion on CPU#0, krxrpcio/7001/1646 lock: 0xffff888141399b30, .magic: dead4ead, .owner: krxrpcio/7001/1646, .owner_cpu: 0 CPU: 0 UID: 0 PID: 1646 Comm: krxrpcio/7001 Not tainted 6.12.0-rc2-build3+ #4351 Hardware name: ASUS All Series/H97-PLUS, BIOS 2306 10/09/2014 Call Trace: dump_stack_lvl+0x47/0x70 do_raw_spin_lock+0x3c/0x90 rxrpc_kernel_shutdown_call+0x83/0xb0 afs_put_call+0xd7/0x180 rxrpc_notify_socket+0xa0/0x190 rxrpc_input_split_jumbo+0x198/0x1d0 rxrpc_input_data+0x14b/0x1e0 ? rxrpc_input_call_packet+0xc2/0x1f0 rxrpc_input_call_event+0xad/0x6b0 rxrpc_input_packet_on_conn+0x1e1/0x210 rxrpc_input_packet+0x3f2/0x4d0 rxrpc_io_thread+0x243/0x410 ? __pfx_rxrpc_io_thread+0x10/0x10 kthread+0xcf/0xe0 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x24/0x40 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1a/0x30

Description: In the Linux kernel, the following vulnerability has been resolved:nvme-multipath: defer partition scanningWe need to suppress the partition scan from occuring within thecontroller's scan_work context. If a path error occurs here, the IO willwait until a path becomes available or all paths are torn down, but thataction also occurs within scan_work, so it would deadlock. Defer thepartion scan to a different context that does not block scan_work.

CVE-2024-53113 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm: fix NULL pointer dereference in alloc_pages_bulk_noprofWe triggered a NULL pointer dereference for ac.preferred_zoneref->zone inalloc_pages_bulk_noprof() when the task is migrated between cpusets.When cpuset is enabled, in prepare_alloc_pages(), ac->nodemask may be¤t->mems_allowed. when first_zones_zonelist() is called to findpreferred_zoneref, the ac->nodemask may be modified concurrently if thetask is migrated between different cpusets. Assuming we have 2 NUMA Node,when traversing Node1 in ac->zonelist, the nodemask is 2, and whentraversing Node2 in ac->zonelist, the nodemask is 1. As a result, theac->preferred_zoneref points to NULL zone.In alloc_pages_bulk_noprof(), for_each_zone_zonelist_nodemask() finds aallowable zone and calls zonelist_node_idx(ac.preferred_zoneref), leadingto NULL pointer dereference.__alloc_pages_noprof() fixes this issue by checking NULL pointer in commitea57485af8f4 ("mm, page_alloc: fix check for NULL preferred_zone") andcommit df76cee6bbeb ("mm, page_alloc: remove redundant checks from allocfastpath").To fix it, check NULL pointer for preferred_zoneref->zone.

CVE-2024-53121 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5: fs, lock FTE when checking if activeThe referenced commits introduced a two-step process for deleting FTEs:- Lock the FTE, delete it from hardware, set the hardware deletion function to NULL and unlock the FTE.- Lock the parent flow group, delete the software copy of the FTE, and remove it from the xarray.However, this approach encounters a race condition if a rule with the samematch value is added simultaneously. In this scenario, fs_core may set thehardware deletion function to NULL prematurely, causing a panic duringsubsequent rule deletions.To prevent this, ensure the active flag of the FTE is checked under a lock,which will prevent the fs_core layer from attaching a new steering rule toan FTE that is in the process of deletion.[ 438.967589] MOSHE: 2496 mlx5_del_flow_rules del_hw_func[ 438.968205] ------------[ cut here ]------------[ 438.968654] refcount_t: decrement hit 0; leaking memory.[ 438.969249] WARNING: CPU: 0 PID: 8957 at lib/refcount.c:31 refcount_warn_saturate+0xfb/0x110[ 438.970054] Modules linked in: act_mirred cls_flower act_gact sch_ingress openvswitch nsh mlx5_vdpa vringh vhost_iotlb vdpa mlx5_ib mlx5_core xt_conntrack xt_MASQUERADE nf_conntrack_netlink nfnetlink xt_addrtype iptable_nat nf_nat br_netfilter rpcsec_gss_krb5 auth_rpcgss oid_registry overlay rpcrdma rdma_ucm ib_iser libiscsi scsi_transport_iscsi ib_umad rdma_cm ib_ipoib iw_cm ib_cm ib_uverbs ib_core zram zsmalloc fuse [last unloaded: cls_flower][ 438.973288] CPU: 0 UID: 0 PID: 8957 Comm: tc Not tainted 6.12.0-rc1+ #8[ 438.973888] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014[ 438.974874] RIP: 0010:refcount_warn_saturate+0xfb/0x110[ 438.975363] Code: 40 66 3b 82 c6 05 16 e9 4d 01 01 e8 1f 7c a0 ff 0f 0b c3 cc cc cc cc 48 c7 c7 10 66 3b 82 c6 05 fd e8 4d 01 01 e8 05 7c a0 ff <0f> 0b c3 cc cc cc cc 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 00 90[ 438.976947] RSP: 0018:ffff888124a53610 EFLAGS: 00010286[ 438.977446] RAX: 0000000000000000 RBX: ffff888119d56de0 RCX: 0000000000000000[ 438.978090] RDX: ffff88852c828700 RSI: ffff88852c81b3c0 RDI: ffff88852c81b3c0[ 438.978721] RBP: ffff888120fa0e88 R08: 0000000000000000 R09: ffff888124a534b0[ 438.979353] R10: 0000000000000001 R11: 0000000000000001 R12: ffff888119d56de0[ 438.979979] R13: ffff888120fa0ec0 R14: ffff888120fa0ee8 R15: ffff888119d56de0[ 438.980607] FS: 00007fe6dcc0f800(0000) GS:ffff88852c800000(0000) knlGS:0000000000000000[ 438.983984] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 438.984544] CR2: 00000000004275e0 CR3: 0000000186982001 CR4: 0000000000372eb0[ 438.985205] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 438.985842] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[ 438.986507] Call Trace:[ 438.986799] [ 438.987070] ? __warn+0x7d/0x110[ 438.987426] ? refcount_warn_saturate+0xfb/0x110[ 438.987877] ? report_bug+0x17d/0x190[ 438.988261] ? prb_read_valid+0x17/0x20[ 438.988659] ? handle_bug+0x53/0x90[ 438.989054] ? exc_invalid_op+0x14/0x70[ 438.989458] ? asm_exc_invalid_op+0x16/0x20[ 438.989883] ? refcount_warn_saturate+0xfb/0x110[ 438.990348] mlx5_del_flow_rules+0x2f7/0x340 [mlx5_core][ 438.990932] __mlx5_eswitch_del_rule+0x49/0x170 [mlx5_core][ 438.991519] ? mlx5_lag_is_sriov+0x3c/0x50 [mlx5_core][ 438.992054] ? xas_load+0x9/0xb0[ 438.992407] mlx5e_tc_rule_unoffload+0x45/0xe0 [mlx5_core][ 438.993037] mlx5e_tc_del_fdb_flow+0x2a6/0x2e0 [mlx5_core][ 438.993623] mlx5e_flow_put+0x29/0x60 [mlx5_core][ 438.994161] mlx5e_delete_flower+0x261/0x390 [mlx5_core][ 438.994728] tc_setup_cb_destroy+0xb9/0x190[ 438.995150] fl_hw_destroy_filter+0x94/0xc0 [cls_flower][ 438.995650] fl_change+0x11a4/0x13c0 [cls_flower][ 438.996105] tc_new_tfilter+0x347/0xbc0[ 438.996503] ? __---truncated---

CVE-2024-53130 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: fix null-ptr-deref in block_dirty_buffer tracepointWhen using the "block:block_dirty_buffer" tracepoint, mark_buffer_dirty()may cause a NULL pointer dereference, or a general protection fault whenKASAN is enabled.This happens because, since the tracepoint was added inmark_buffer_dirty(), it references the dev_t member bh->b_bdev->bd_devregardless of whether the buffer head has a pointer to a block_devicestructure.In the current implementation, nilfs_grab_buffer(), which grabs a bufferto read (or create) a block of metadata, including b-tree node blocks,does not set the block device, but instead does so only if the buffer isnot in the "uptodate" state for each of its caller block readingfunctions. However, if the uptodate flag is set on a folio/page, and thebuffer heads are detached from it by try_to_free_buffers(), and new bufferheads are then attached by create_empty_buffers(), the uptodate flag maybe restored to each buffer without the block device being set tobh->b_bdev, and mark_buffer_dirty() may be called later in that state,resulting in the bug mentioned above.Fix this issue by making nilfs_grab_buffer() always set the block deviceof the super block structure to the buffer head, regardless of the stateof the buffer's uptodate flag.

CVE-2024-53131 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: fix null-ptr-deref in block_touch_buffer tracepointPatch series "nilfs2: fix null-ptr-deref bugs on block tracepoints".This series fixes null pointer dereference bugs that occur when usingnilfs2 and two block-related tracepoints.This patch (of 2):It has been reported that when using "block:block_touch_buffer"tracepoint, touch_buffer() called from __nilfs_get_folio_block() causes aNULL pointer dereference, or a general protection fault when KASAN isenabled.This happens because since the tracepoint was added in touch_buffer(), itreferences the dev_t member bh->b_bdev->bd_dev regardless of whether thebuffer head has a pointer to a block_device structure. In the currentimplementation, the block_device structure is set after the functionreturns to the caller.Here, touch_buffer() is used to mark the folio/page that owns the bufferhead as accessed, but the common search helper for folio/page used by thecaller function was optimized to mark the folio/page as accessed when itwas reimplemented a long time ago, eliminating the need to calltouch_buffer() here in the first place.So this solves the issue by eliminating the touch_buffer() call itself.

CVE-2024-53140 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:netlink: terminate outstanding dump on socket closeNetlink supports iterative dumping of data. It provides the familiesthe following ops: - start - (optional) kicks off the dumping process - dump - actual dump helper, keeps getting called until it returns 0 - done - (optional) pairs with .start, can be used for cleanupThe whole process is asynchronous and the repeated calls to .dumpdon't actually happen in a tight loop, but rather are triggeredin response to recvmsg() on the socket.This gives the user full control over the dump, but also means thatthe user can close the socket without getting to the end of the dump.To make sure .start is always paired with .done we check if thereis an ongoing dump before freeing the socket, and if so call .done.The complication is that sockets can get freed from BH and .doneis allowed to sleep. So we use a workqueue to defer the call, whenneeded.Unfortunately this does not work correctly. What we defer is notthe cleanup but rather releasing a reference on the socket.We have no guarantee that we own the last reference, if someoneelse holds the socket they may release it in BH and we're backto square one.The whole dance, however, appears to be unnecessary. Only the usercan interact with dumps, so we can clean up when socket is closed.And close always happens in process context. Some async code maystill access the socket after close, queue notification skbs to it etc.but no dumps can start, end or otherwise make progress.Delete the workqueue and flush the dump state directly from the releasehandler. Note that further cleanup is possible in -next, for instancewe now always call .done before releasing the main module reference,so dump doesn't have to take a reference of its own.

As for now, the maximal read size for kvec iter isonly limited by fc->max_read. For virtio-fs, max_read is UINT_MAX, sofuse_direct_io() doesn't split the 10MB buffer. It saves the address andthe size of the 10MB-sized buffer in out_args[0] of a fuse request andpasses the fuse request to virtio_fs_wake_pending_and_unlock().4) virtio_fs_wake_pending_and_unlock() uses virtio_fs_enqueue_req() toqueue the request. Because virtiofs need DMA-able address, sovirtio_fs_enqueue_req() uses kmalloc() to allocate a bounce buffer forall fuse args, copies these args into the bounce buffer and passed thephysical address of the bounce buffer to virtiofsd. The total length ofthese fuse args for the passed fuse request is about 10MB, socopy_args_to_argbuf() invokes kmalloc() with a 10MB size parameter andit triggers the warning in __alloc_pages(): if (WARN_ON_ONCE_GFP(order > MAX_PAGE_ORDER, gfp)) return NULL;5) virtio_fs_enqueue_req() will retry the memory allocation in akworker, but it won't help, because kmalloc() will always return NULLdue to the abnormal size and finit_module() will hang forever.A feasible solution is to limit the value of max_read for virtio-fs, sothe length passed to kmalloc() will be limited. However it will affectthe maximal read size for normal read. And for virtio-fs write initiatedfrom kernel, it has the similar problem but now there is no way to limitfc->max_write in kernel.So instead of limiting both the values of max_read and max_write inkernel, introducing use_pages_for_kvec_io in fuse_conn and setting it astrue in virtiofs. When use_pages_for_kvec_io is enabled, fuse will usepages instead of pointer to pass the KVEC_IO data.After switching to pages for KVEC_IO data, these pages will be used forDMA through virtio-fs. If these pages are backed by vmalloc(),{flush|invalidate}_kernel_vmap_range() are necessary to flush orinvalidate the cache before the DMA operation. So add two new fields infuse_args_pages to record the base address of vmalloc area and thecondition indicating whether invalidation is needed. Perform the flushin fuse_get_user_pages() for write operations and the invalidation infuse_release_user_pages() for read operations.It may seem necessary to introduce another fie---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: ref-verify: fix use-after-free after invalid ref actionAt btrfs_ref_tree_mod() after we successfully inserted the new ref entry(local variable 'ref') into the respective block entry's rbtree (localvariable 'be'), if we find an unexpected action of BTRFS_DROP_DELAYED_REF,we error out and free the ref entry without removing it from the blockentry's rbtree. Then in the error path of btrfs_ref_tree_mod() we callbtrfs_free_ref_cache(), which iterates over all block entries and thencalls free_block_entry() for each one, and there we will trigger ause-after-free when we are called against the block entry to which weadded the freed ref entry to its rbtree, since the rbtree still pointsto the block entry, as we didn't remove it from the rbtree before freeingit in the error path at btrfs_ref_tree_mod(). Fix this by removing thenew ref entry from the rbtree before freeing it.Syzbot report this with the following stack traces: BTRFS error (device loop0 state EA): Ref action 2, root 5, ref_root 0, parent 8564736, owner 0, offset 0, num_refs 18446744073709551615 __btrfs_mod_ref+0x7dd/0xac0 fs/btrfs/extent-tree.c:2523 update_ref_for_cow+0x9cd/0x11f0 fs/btrfs/ctree.c:512 btrfs_force_cow_block+0x9f6/0x1da0 fs/btrfs/ctree.c:594 btrfs_cow_block+0x35e/0xa40 fs/btrfs/ctree.c:754 btrfs_search_slot+0xbdd/0x30d0 fs/btrfs/ctree.c:2116 btrfs_insert_empty_items+0x9c/0x1a0 fs/btrfs/ctree.c:4314 btrfs_insert_empty_item fs/btrfs/ctree.h:669 [inline] btrfs_insert_orphan_item+0x1f1/0x320 fs/btrfs/orphan.c:23 btrfs_orphan_add+0x6d/0x1a0 fs/btrfs/inode.c:3482 btrfs_unlink+0x267/0x350 fs/btrfs/inode.c:4293 vfs_unlink+0x365/0x650 fs/namei.c:4469 do_unlinkat+0x4ae/0x830 fs/namei.c:4533 __do_sys_unlinkat fs/namei.c:4576 [inline] __se_sys_unlinkat fs/namei.c:4569 [inline] __x64_sys_unlinkat+0xcc/0xf0 fs/namei.c:4569 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xf3/0x230 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7f BTRFS error (device loop0 state EA): Ref action 1, root 5, ref_root 5, parent 0, owner 260, offset 0, num_refs 1 __btrfs_mod_ref+0x76b/0xac0 fs/btrfs/extent-tree.c:2521 update_ref_for_cow+0x96a/0x11f0 btrfs_force_cow_block+0x9f6/0x1da0 fs/btrfs/ctree.c:594 btrfs_cow_block+0x35e/0xa40 fs/btrfs/ctree.c:754 btrfs_search_slot+0xbdd/0x30d0 fs/btrfs/ctree.c:2116 btrfs_lookup_inode+0xdc/0x480 fs/btrfs/inode-item.c:411 __btrfs_update_delayed_inode+0x1e7/0xb90 fs/btrfs/delayed-inode.c:1030 btrfs_update_delayed_inode fs/btrfs/delayed-inode.c:1114 [inline] __btrfs_commit_inode_delayed_items+0x2318/0x24a0 fs/btrfs/delayed-inode.c:1137 __btrfs_run_delayed_items+0x213/0x490 fs/btrfs/delayed-inode.c:1171 btrfs_commit_transaction+0x8a8/0x3740 fs/btrfs/transaction.c:2313 prepare_to_relocate+0x3c4/0x4c0 fs/btrfs/relocation.c:3586 relocate_block_group+0x16c/0xd40 fs/btrfs/relocation.c:3611 btrfs_relocate_block_group+0x77d/0xd90 fs/btrfs/relocation.c:4081 btrfs_relocate_chunk+0x12c/0x3b0 fs/btrfs/volumes.c:3377 __btrfs_balance+0x1b0f/0x26b0 fs/btrfs/volumes.c:4161 btrfs_balance+0xbdc/0x10c0 fs/btrfs/volumes.c:4538 BTRFS error (device loop0 state EA): Ref action 2, root 5, ref_root 0, parent 8564736, owner 0, offset 0, num_refs 18446744073709551615 __btrfs_mod_ref+0x7dd/0xac0 fs/btrfs/extent-tree.c:2523 update_ref_for_cow+0x9cd/0x11f0 fs/btrfs/ctree.c:512 btrfs_force_cow_block+0x9f6/0x1da0 fs/btrfs/ctree.c:594 btrfs_cow_block+0x35e/0xa40 fs/btrfs/ctree.c:754 btrfs_search_slot+0xbdd/0x30d0 fs/btrfs/ctree.c:2116 btrfs_lookup_inode+0xdc/0x480 fs/btrfs/inode-item.c:411 __btrfs_update_delayed_inode+0x1e7/0xb90 fs/btrfs/delayed-inode.c:1030 btrfs_update_delayed_i---truncated---

If the task is boosted, the warningis triggered. A boosted task already had its parameters set byrt_mutex_setprio, and a new call to setup_new_dl_entity is unnecessary,hence the WARN_ON call.Check if we are requeueing a boosted task and avoid callingsetup_new_dl_entity if that's the case.

In theperformance test scenario, function irq_wait_for_interrupt() will alwaysreturn 0 if lots of interrupts occurs and the CPU will be continuouslyconsumed. As a result, the CPU cannot run the watchdog thread. When thewatchdog time exceeds the specified time, call trace occurs.To fix it, add cond_resched() to execute the watchdog thread.

However,bpf_map_fd_put_ptr() is invoked while holding a bucket lock(raw_spin_lock_t), and bpf_map_free_id() attempts to acquire map_idr_lock(spinlock_t), triggering the following lockdep warning: ============================= [ BUG: Invalid wait context ] 6.11.0-rc4+ #49 Not tainted ----------------------------- test_maps/4881 is trying to lock: ffffffff84884578 (map_idr_lock){+...}-{3:3}, at: bpf_map_free_id.part.0+0x21/0x70 other info that might help us debug this: context-{5:5} 2 locks held by test_maps/4881: #0: ffffffff846caf60 (rcu_read_lock){....}-{1:3}, at: bpf_fd_htab_map_update_elem+0xf9/0x270 #1: ffff888149ced148 (&htab->lockdep_key#2){....}-{2:2}, at: htab_map_update_elem+0x178/0xa80 stack backtrace: CPU: 0 UID: 0 PID: 4881 Comm: test_maps Not tainted 6.11.0-rc4+ #49 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), ...

However, bpf_map_alloc_id() invokesidr_alloc_cyclic() after acquiring map_idr_lock, it will trigger asimilar lockdep warning because the slab's lock (s->cpu_slab->lock) isstill a spinlock.Instead of changing map_idr_lock's type, fix the issue by invokinghtab_put_fd_value() after htab_unlock_bucket(). However, only deferringthe invocation of htab_put_fd_value() is not enough, because the old mappointers in htab of maps can not be saved during batched deletion.Therefore, also defer the invocation of free_htab_elem(), so theseto-be-freed elements could be linked together similar to lru map.There are four callers for ->map_fd_put_ptr:(1) alloc_htab_elem() (through htab_put_fd_value())It invokes ->map_fd_put_ptr() under a raw_spinlock_t. The invocation ofhtab_put_fd_value() can not simply move after htab_unlock_bucket(),because the old element has already been stashed in htab->extra_elems.It may be reused immediately after htab_unlock_bucket() and theinvocation of htab_put_fd_value() after htab_unlock_bucket() may releasethe newly-added element incorrectly. Therefore, saving the map pointerof the old element for htab of maps before unlocking the bucket andreleasing the map_ptr after unlock. Beside the map pointer in the oldelement, should do the same thing for the special fields in the oldelement as well.(2) free_htab_elem() (through htab_put_fd_value())Its caller includes __htab_map_lookup_and_delete_elem(),htab_map_delete_elem() and __htab_map_lookup_and_delete_batch().For htab_map_delete_elem(), simply invoke free_htab_elem() afterhtab_unlock_bucket(). For __htab_map_lookup_and_delete_batch(), justlike lru map, linking the to-be-freed element into node_to_free listand invoking free_htab_elem() for these element after unlock. It is safeto reuse batch_flink as the link for node_to_free, because theseelements have been removed from the hash llist.Because htab of maps doesn't support lookup_and_delete operation,__htab_map_lookup_and_delete_elem() doesn't have the problem, so keptit as---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: brcmfmac: Fix oops due to NULL pointer dereference in brcmf_sdiod_sglist_rw()This patch fixes a NULL pointer dereference bug in brcmfmac that occurswhen a high 'sd_sgentry_align' value applies (e.g. 512) and a lot of queued SKBsare sent from the pkt queue.The problem is the number of entries in the pre-allocated sgtable, it isnents = max(rxglom_size, txglom_size) + max(rxglom_size, txglom_size) >> 4 + 1.Given the default [rt]xglom_size=32 it's actually 35 which is too small.Worst case, the pkt queue can end up with 64 SKBs. This occurs when a new SKBis added for each original SKB if tailroom isn't enough to hold tail_pad.At least one sg entry is needed for each SKB. So, eventually the "skb_queue_walk loop"in brcmf_sdiod_sglist_rw may run out of sg entries. This makes sg_next returnNULL and this causes the oops.The patch sets nents to max(rxglom_size, txglom_size) * 2 to be able handlethe worst-case.Btw. this requires only 64-35=29 * 16 (or 20 if CONFIG_NEED_SG_DMA_LENGTH) = 464additional bytes of memory.

CVE-2024-56615 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: fix OOB devmap writes when deleting elementsJordy reported issue against XSKMAP which also applies to DEVMAP - theindex used for accessing map entry, due to being a signed integer,causes the OOB writes. Fix is simple as changing the type from int tou32, however, when compared to XSKMAP case, one more thing needs to beaddressed.When map is released from system via dev_map_free(), we iterate throughall of the entries and an iterator variable is also an int, whichimplies OOB accesses. Again, change it to be u32.Example splat below:[ 160.724676] BUG: unable to handle page fault for address: ffffc8fc2c001000[ 160.731662] #PF: supervisor read access in kernel mode[ 160.736876] #PF: error_code(0x0000) - not-present page[ 160.742095] PGD 0 P4D 0[ 160.744678] Oops: Oops: 0000 [#1] PREEMPT SMP[ 160.749106] CPU: 1 UID: 0 PID: 520 Comm: kworker/u145:12 Not tainted 6.12.0-rc1+ #487[ 160.757050] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019[ 160.767642] Workqueue: events_unbound bpf_map_free_deferred[ 160.773308] RIP: 0010:dev_map_free+0x77/0x170[ 160.777735] Code: 00 e8 fd 91 ed ff e8 b8 73 ed ff 41 83 7d 18 19 74 6e 41 8b 45 24 49 8b bd f8 00 00 00 31 db 85 c0 74 48 48 63 c3 48 8d 04 c7 <48> 8b 28 48 85 ed 74 30 48 8b 7d 18 48 85 ff 74 05 e8 b3 52 fa ff[ 160.796777] RSP: 0018:ffffc9000ee1fe38 EFLAGS: 00010202[ 160.802086] RAX: ffffc8fc2c001000 RBX: 0000000080000000 RCX: 0000000000000024[ 160.809331] RDX: 0000000000000000 RSI: 0000000000000024 RDI: ffffc9002c001000[ 160.816576] RBP: 0000000000000000 R08: 0000000000000023 R09: 0000000000000001[ 160.823823] R10: 0000000000000001 R11: 00000000000ee6b2 R12: dead000000000122[ 160.831066] R13: ffff88810c928e00 R14: ffff8881002df405 R15: 0000000000000000[ 160.838310] FS: 0000000000000000(0000) GS:ffff8897e0c40000(0000) knlGS:0000000000000000[ 160.846528] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 160.852357] CR2: ffffc8fc2c001000 CR3: 0000000005c32006 CR4: 00000000007726f0[ 160.859604] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 160.866847] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[ 160.874092] PKRU: 55555554[ 160.876847] Call Trace:[ 160.879338] [ 160.881477] ? __die+0x20/0x60[ 160.884586] ? page_fault_oops+0x15a/0x450[ 160.888746] ? search_extable+0x22/0x30[ 160.892647] ? search_bpf_extables+0x5f/0x80[ 160.896988] ? exc_page_fault+0xa9/0x140[ 160.900973] ? asm_exc_page_fault+0x22/0x30[ 160.905232] ? dev_map_free+0x77/0x170[ 160.909043] ? dev_map_free+0x58/0x170[ 160.912857] bpf_map_free_deferred+0x51/0x90[ 160.917196] process_one_work+0x142/0x370[ 160.921272] worker_thread+0x29e/0x3b0[ 160.925082] ? rescuer_thread+0x4b0/0x4b0[ 160.929157] kthread+0xd4/0x110[ 160.932355] ? kthread_park+0x80/0x80[ 160.936079] ret_from_fork+0x2d/0x50[ 160.943396] ? kthread_park+0x80/0x80[ 160.950803] ret_from_fork_asm+0x11/0x20[ 160.958482]

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: imx6: Fix suspend/resume support on i.MX6QDLThe suspend/resume functionality is currently broken on the i.MX6QDLplatform, as documented in the NXP errata (ERR005723): https://www.nxp.com/docs/en/errata/IMX6DQCE.pdfThis patch addresses the issue by sharing most of the suspend/resumesequences used by other i.MX devices, while avoiding modifications tocritical registers that disrupt the PCIe functionality. It targets thesame problem as the following downstream commit: https://github.com/nxp-imx/linux-imx/commit/4e92355e1f79d225ea842511fcfd42b343b32995Unlike the downstream commit, this patch also resets the connected PCIedevice if possible. Without this reset, certain drivers, such as ath10kor iwlwifi, will crash on resume. The device reset is also done by thedriver on other i.MX platforms, making this patch consistent withexisting practices.Upon resuming, the kernel will hang and display an error. Here's anexample of the error encountered with the ath10k driver: ath10k_pci 0000:01:00.0: Unable to change power state from D3hot to D0, device inaccessible Unhandled fault: imprecise external abort (0x1406) at 0x0106f944Without this patch, suspend/resume will fail on i.MX6QDL devices if aPCIe device is connected.[kwilczynski: commit log, added tag for stable releases]

Additionally, since this system lacks swap, the calculation of inactive/active anonymous pages is skipped. crash> p nr_swap_pages nr_swap_pages = $1937 = { counter = 0 }As a result, ZONE_DMA32 is deemed unreclaimable and skipped, moving on tothe processing of the next zone, ZONE_NORMAL, despite ZONE_DMA32 havingfree pages significantly exceeding the high watermark.The problem is that the pgdat->kswapd_failures hasn't been incremented. crash> px ((struct pglist_data *) 0xffff00817fffe540)->kswapd_failures $1935 = 0x0This is because the node deemed balanced. The node balancing logic inbalance_pgdat() evaluates all zones collectively. If one or more zones(e.g., ZONE_DMA32) have enough free pages to meet their watermarks, theentire node is deemed balanced. This causes balance_pgdat() to exit earlybefore incrementing the kswapd_failures, as it considers the overallmemory state acceptable, even though some zones (like ZONE_NORMAL) remainunder significant pressure.The patch ensures that zone_reclaimable_pages() includes free pages(NR_FREE_PAGES) in its calculation when no other reclaimable pages areavailable (e.g., file-backed or anonymous pages). This change preventszones like ZONE_DMA32, which have sufficient free pages, from beingmistakenly deemed unreclaimable. By doing so, the patch ensures propernode balancing, avoids masking pressure on other zones like ZONE_NORMAL,and prevents infinite loops in throttle_direct_reclaim() caused byallow_direct_reclaim(pgdat) repeatedly returning false.The kernel hangs due to a task stuck in throttle_direct_reclaim(), causedby a node being incorrectly deemed balanced despite pressure in certainzones, such as ZONE_NORMAL. This issue arises fromzone_reclaimable_pages---truncated---

The latter takesmcp->lock and enables regmap caching, so that the potentially slow I2Caccesses are deferred until chip_bus_unlock().The accesses to the regmap from mcp23s08_probe_one() do not need additionallocking.In all remaining places where the regmap is accessed, exceptmcp_pinconf_get/set(), the driver already takes mcp->lock.This patch adds locking in mcp_pinconf_get/set() and disables internallocking in the regmap config. Among other things, it fixes the sleepingin atomic context described above.

CVE-2024-57892 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ocfs2: fix slab-use-after-free due to dangling pointer dqi_privWhen mounting ocfs2 and then remounting it as read-only, aslab-use-after-free occurs after the user uses a syscall toquota_getnextquota. Specifically, sb_dqinfo(sb, type)->dqi_priv is thedangling pointer.During the remounting process, the pointer dqi_priv is freed but is neverset as null leaving it to be accessed. Additionally, the read-only optionfor remounting sets the DQUOT_SUSPENDED flag instead of setting theDQUOT_USAGE_ENABLED flags. Moreover, later in the process of getting thenext quota, the function ocfs2_get_next_id is called and only checks thequota usage flags and not the quota suspended flags.To fix this, I set dqi_priv to null when it is freed after remounting withread-only and put a check for DQUOT_SUSPENDED in ocfs2_get_next_id.[akpm@linux-foundation.org: coding-style cleanups]

CVE-2024-57924 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fs: relax assertions on failure to encode file handlesEncoding file handles is usually performed by a filesystem >encode_fh()method that may fail for various reasons.The legacy users of exportfs_encode_fh(), namely, nfsd andname_to_handle_at(2) syscall are ready to cope with the possibilityof failure to encode a file handle.There are a few other users of exportfs_encode_{fh,fid}() thatcurrently have a WARN_ON() assertion when ->encode_fh() fails.Relax those assertions because they are wrong.The second linked bug report states commit 16aac5ad1fa9 ("ovl: supportencoding non-decodable file handles") in v6.6 as the regressing commit,but this is not accurate.The aforementioned commit only increases the chances of the assertionand allows triggering the assertion with the reproducer using overlayfs,inotify and drop_caches.Triggering this assertion was always possible with other filesystems andother reasons of ->encode_fh() failures and more particularly, it wasalso possible with the exact same reproducer using overlayfs that ismounted with options index=on,nfs_export=on also on kernels < v6.6.Therefore, I am not listing the aforementioned commit as a Fixes commit.Backport hint: this patch will have a trivial conflict applying tov6.6.y, and other trivial conflicts applying to stable kernels < v6.6.

Description: In the Linux kernel, the following vulnerability has been resolved:gve: guard XDP xmit NDO on existence of xdp queuesIn GVE, dedicated XDP queues only exist when an XDP program is installedand the interface is up. As such, the NDO XDP XMIT callback shouldreturn early if either of these conditions are false.In the case of no loaded XDP program, priv->num_xdp_queues=0 which cancause a divide-by-zero error, and in the case of interface down,num_xdp_queues remains untouched to persist XDP queue count for the nextinterface up, but the TX pointer itself would be NULL.The XDP xmit callback also needs to synchronize with a devicetransitioning from open to close. This synchronization will happen viathe GVE_PRIV_FLAGS_NAPI_ENABLED bit along with a synchronize_net() call,which waits for any RCU critical sections at call-time to complete.

Description: In the Linux kernel, the following vulnerability has been resolved:gve: guard XSK operations on the existence of queuesThis patch predicates the enabling and disabling of XSK pools on theexistence of queues. As it stands, if the interface is down, disablingor enabling XSK pools would result in a crash, as the RX queue pointerwould be NULL. XSK pool registration will occur as part of the nextinterface up.Similarly, xsk_wakeup needs be guarded against queues disappearingwhile the function is executing, so a check against theGVE_PRIV_FLAGS_NAPI_ENABLED flag is added to synchronize with thedisabling of the bit and the synchronize_net() in gve_turndown.

Description: In the Linux kernel, the following vulnerability has been resolved:udp: Deal with race between UDP socket address change and rehashIf a UDP socket changes its local address while it's receivingdatagrams, as a result of connect(), there is a period during whicha lookup operation might fail to find it, after the address is changedbut before the secondary hash (port and address) and the four-tuplehash (local and remote ports and addresses) are updated.Secondary hash chains were introduced by commit 30fff9231fad ("udp:bind() optimisation") and, as a result, a rehash operation becameneeded to make a bound socket reachable again after a connect().This operation was introduced by commit 719f835853a9 ("udp: addrehash on connect()") which isn't however a complete fix: thesocket will be found once the rehashing completes, but not whileit's pending.This is noticeable with a socat(1) server in UDP4-LISTEN mode, and aclient sending datagrams to it.

Kernel panic - not syncing: Oops - BUG: Fatal exceptionThis happens because pps_device_destruct() frees the pps_device with theembedded cdev immediately after calling cdev_del(), but, as the commentabove cdev_del() notes, fops for previously opened cdevs are stillcallable even after cdev_del() returns. I think this bug has alwaysbeen there: I can't explain why it suddenly started happening every timeI reboot this particular board.In commit d953e0e837e6 ("pps: Fix a use-after free bug whenunregistering a source."), George Spelvin suggested removing theembedded cdev. That seems like the simplest way to fix this, so I'veimplemented his suggestion, using __register_chrdev() with pps_idrbecoming the source of truth for which minor corresponds to whichdevice.But now that pps_idr defines userspace visibility instead of cdev_add(),we need to be sure the pps->dev refcount can't reach zero whileuserspace can still find it again. So, the idr_remove() call moves topps_unregister_cdev(), and pps_idr now holds a reference to pps->dev. pps_core: source serial1 got cdev (251:1) <...> pps pps1: removed pps_core: unregistering pps1 pps_core: deallocating pps1

Description: In the Linux kernel, the following vulnerability has been resolved:usb: xhci: Fix NULL pointer dereference on certain command abortsIf a command is queued to the final usable TRB of a ring segment, theenqueue pointer is advanced to the subsequent link TRB and no further.If the command is later aborted, when the abort completion is handledthe dequeue pointer is advanced to the first TRB of the next segment.If no further commands are queued, xhci_handle_stopped_cmd_ring() seesthe ring pointers unequal and assumes that there is a pending command,so it calls xhci_mod_cmd_timer() which crashes if cur_cmd was NULL.Don't attempt timer setup if cur_cmd is NULL. The subsequent doorbellring likely is unnecessary too, but it's harmless. Leave it alone.This is probably Bug 219532, but no confirmation has been received.The issue has been independently reproduced and confirmed fixed usinga USB MCU programmed to NAK the Status stage of SET_ADDRESS forever.Everything continued working normally after several prevented crashes.

Description: In the Linux kernel, the following vulnerability has been resolved:xfrm: state: fix out-of-bounds read during lookuplookup and resize can run in parallel.The xfrm_state_hash_generation seqlock ensures a retry, but the hashfunctions can observe a hmask value that is too large for the new hlistarray.rehash does: rcu_assign_pointer(net->xfrm.state_bydst, ndst) [..] net->xfrm.state_hmask = nhashmask;While state lookup does: h = xfrm_dst_hash(net, daddr, saddr, tmpl->reqid, encap_family); hlist_for_each_entry_rcu(x, net->xfrm.state_bydst + h, bydst) {This is only safe in case the update to state_bydst is larger thannet->xfrm.xfrm_state_hmask (or if the lookup function getsserialized via state spinlock again).Fix this by prefetching state_hmask and the associated pointers.The xfrm_state_hash_generation seqlock retry will ensure that the pointerand the hmask will be consistent.The existing helpers, like xfrm_dst_hash(), are now unsafe for RCU side,add lockdep assertions to document that they are only safe for insertside.xfrm_state_lookup_byaddr() uses the spinlock rather than RCU.AFAICS this is an oversight from back when state lookup was converted toRCU, this lock should be replaced with RCU in a future patch.

CVE-2024-57986 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:HID: core: Fix assumption that Resolution Multipliers must be in Logical CollectionsA report in 2019 by the syzbot fuzzer was found to be connected to twoerrors in the HID core associated with Resolution Multipliers. One ofthe errors was fixed by commit ea427a222d8b ("HID: core: Fix deadloopin hid_apply_multiplier."), but the other has not been fixed.This error arises because hid_apply_multipler() assumes that everyResolution Multiplier control is contained in a Logical Collection,i.e., there's no way the routine can ever set multiplier_collection toNULL. This is in spite of the fact that the function starts with abig comment saying: * "The Resolution Multiplier control must be contained in the same * Logical Collection as the control(s) to which it is to be applied. ... * If no Logical Collection is * defined, the Resolution Multiplier is associated with all * controls in the report." * HID Usage Table, v1.12, Section 4.3.1, p30 * * Thus, search from the current collection upwards until we find a * logical collection...The comment and the code overlook the possibility that none of thecollections found may be a Logical Collection.The fix is to set the multiplier_collection pointer to NULL if thecollection found isn't a Logical Collection.

Description: In the Linux kernel, the following vulnerability has been resolved:media: uvcvideo: Remove dangling pointersWhen an async control is written, we copy a pointer to the file handlethat started the operation. That pointer will be used when the device isdone. Which could be anytime in the future.If the user closes that file descriptor, its structure will be freed,and there will be one dangling pointer per pending async control, thatthe driver will try to use.Clean all the dangling pointers during release().To avoid adding a performance penalty in the most common case (no asyncoperation), a counter has been introduced with some logic to make surethat it is properly handled.

CVE-2024-58007 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:soc: qcom: socinfo: Avoid out of bounds read of serial numberOn MSM8916 devices, the serial number exposed in sysfs is constant and doesnot change across individual devices. It's always: db410c:/sys/devices/soc0$ cat serial_number 2644893864The firmware used on MSM8916 exposes SOCINFO_VERSION(0, 8), which does nothave support for the serial_num field in the socinfo struct. There is anexisting check to avoid exposing the serial number in that case, but it'snot correct: When checking the item_size returned by SMEM, we need to makesure the *end* of the serial_num is within bounds, instead of comparingwith the *start* offset. The serial_number currently exposed on MSM8916devices is just an out of bounds read of whatever comes after the socinfostruct in SMEM.Fix this by changing offsetof() to offsetofend(), so that the size of thefield is also taken into account.

The channel would be removed from the list in short period of timebut be a bit more straight-forward here and just check for NULL instead ofchanging the order of function calls.Found by Linux Verification Center (linuxtesting.org) with SVACE staticanalysis tool.

CVE-2024-58057 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:idpf: convert workqueues to unboundWhen a workqueue is created with `WQ_UNBOUND`, its work items areserved by special worker-pools, whose host workers are not bound toany specific CPU. In the default configuration (i.e. when`queue_delayed_work` and friends do not specify which CPU to run thework item on), `WQ_UNBOUND` allows the work item to be executed on anyCPU in the same node of the CPU it was enqueued on. While thissolution potentially sacrifices locality, it avoids contention withother processes that might dominate the CPU time of the processor thework item was scheduled on.This is not just a theoretical problem: in a particular scenariomisconfigured process was hogging most of the time from CPU0, leavingless than 0.5% of its CPU time to the kworker. The IDPF workqueuesthat were using the kworker on CPU0 suffered large completion delaysas a result, causing performance degradation, timeouts and eventualsystem crash.* I have also run a manual test to gauge the performance improvement. The test consists of an antagonist process (`./stress --cpu 2`) consuming as much of CPU 0 as possible. This process is run under `taskset 01` to bind it to CPU0, and its priority is changed with `chrt -pQ 9900 10000 ${pid}` and `renice -n -20 ${pid}` after start. Then, the IDPF driver is forced to prefer CPU0 by editing all calls to `queue_delayed_work`, `mod_delayed_work`, etc... to use CPU 0. Finally, `ktraces` for the workqueue events are collected. Without the current patch, the antagonist process can force arbitrary delays between `workqueue_queue_work` and `workqueue_execute_start`, that in my tests were as high as `30ms`. With the current patch applied, the workqueue can be migrated to another unloaded CPU in the same node, and, keeping everything else equal, the maximum delay I could see was `6us`.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: rtlwifi: remove unused check_buddy_privCommit 2461c7d60f9f ("rtlwifi: Update header file") introduced a globallist of private data structures.Later on, commit 26634c4b1868 ("rtlwifi Modify existing bits to matchvendor version 2013.02.07") started adding the private data to that list atprobe time and added a hook, check_buddy_priv to find the private data froma similar device.However, that function was never used.Besides, though there is a lock for that list, it is never used. And whenthe probe fails, the private data is never removed from the list. Thiswould cause a second probe to access freed memory.Remove the unused hook, structures and members, which will prevent thepotential race condition on the list and its corruption during a secondprobe when probe fails.

Description: In the Linux kernel, the following vulnerability has been resolved:media: uvcvideo: Fix crash during unbind if gpio unit is in useWe used the wrong device for the device managed functions. We used theusb device, when we should be using the interface device.If we unbind the driver from the usb interface, the cleanup functionsare never called. In our case, the IRQ is never disabled.If an IRQ is triggered, it will try to access memory sections that arealready free, causing an OOPS.We cannot use the function devm_request_threaded_irq here. The devm_*clean functions may be called after the main structure is released byuvc_delete.Luckily this bug has small impact, as it is only affected by deviceswith gpio units and the user has to unbind the device, a disconnect willnot trigger this error.

CVE-2024-58090 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:sched/core: Prevent rescheduling when interrupts are disabledDavid reported a warning observed while loop testing kexec jump: Interrupts enabled after irqrouter_resume+0x0/0x50 WARNING: CPU: 0 PID: 560 at drivers/base/syscore.c:103 syscore_resume+0x18a/0x220 kernel_kexec+0xf6/0x180 __do_sys_reboot+0x206/0x250 do_syscall_64+0x95/0x180The corresponding interrupt flag trace: hardirqs last enabled at (15573): [] __up_console_sem+0x7e/0x90 hardirqs last disabled at (15580): [] __up_console_sem+0x63/0x90That means __up_console_sem() was invoked with interrupts enabled. Furtherinstrumentation revealed that in the interrupt disabled section of kexecjump one of the syscore_suspend() callbacks woke up a task, which set theNEED_RESCHED flag. A later callback in the resume path invokedcond_resched() which in turn led to the invocation of the scheduler: __cond_resched+0x21/0x60 down_timeout+0x18/0x60 acpi_os_wait_semaphore+0x4c/0x80 acpi_ut_acquire_mutex+0x3d/0x100 acpi_ns_get_node+0x27/0x60 acpi_ns_evaluate+0x1cb/0x2d0 acpi_rs_set_srs_method_data+0x156/0x190 acpi_pci_link_set+0x11c/0x290 irqrouter_resume+0x54/0x60 syscore_resume+0x6a/0x200 kernel_kexec+0x145/0x1c0 __do_sys_reboot+0xeb/0x240 do_syscall_64+0x95/0x180This is a long standing problem, which probably got more visible withthe recent printk changes. Something does a task wakeup and thescheduler sets the NEED_RESCHED flag. cond_resched() sees it set andinvokes schedule() from a completely bogus context. The schedulerenables interrupts after context switching, which causes the abovewarning at the end.Quite some of the code paths in syscore_suspend()/resume() can result intriggering a wakeup with the exactly same consequences. They might nothave done so yet, but as they share a lot of code with normal operationsit's just a question of time.The problem only affects the PREEMPT_NONE and PREEMPT_VOLUNTARY schedulingmodels. Full preemption is not affected as cond_resched() is disabled andthe preemption check preemptible() takes the interrupt disabled flag intoaccount.Cure the problem by adding a corresponding check into cond_resched().

CVE-2024-58093 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:PCI/ASPM: Fix link state exit during switch upstream function removalBefore 456d8aa37d0f ("PCI/ASPM: Disable ASPM on MFD function removal toavoid use-after-free"), we would free the ASPM link only after the lastfunction on the bus pertaining to the given link was removed.That was too late. If function 0 is removed before sibling function,link->downstream would point to free'd memory after.After above change, we freed the ASPM parent link state upon any functionremoval on the bus pertaining to a given link.That is too early. If the link is to a PCIe switch with MFD on the upstreamport, then removing functions other than 0 first would free a link whichstill remains parent_link to the remaining downstream ports.The resulting GPFs are especially frequent during hot-unplug, becausepciehp removes devices on the link bus in reverse order.On that switch, function 0 is the virtual P2P bridge to the internal bus.Free exactly when function 0 is removed -- before the parent link isobsolete, but after all subordinate links are gone.[kwilczynski: commit log]

CVE-2024-58098 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: track changes_pkt_data property for global functionsWhen processing calls to certain helpers, verifier invalidates allpacket pointers in a current state. For example, consider thefollowing program: __attribute__((__noinline__)) long skb_pull_data(struct __sk_buff *sk, __u32 len) { return bpf_skb_pull_data(sk, len); } SEC("tc") int test_invalidate_checks(struct __sk_buff *sk) { int *p = (void *)(long)sk->data; if ((void *)(p + 1) > (void *)(long)sk->data_end) return TCX_DROP; skb_pull_data(sk, 0); *p = 42; return TCX_PASS; }After a call to bpf_skb_pull_data() the pointer 'p' can't be usedsafely. See function filter.c:bpf_helper_changes_pkt_data() for a listof such helpers.At the moment verifier invalidates packet pointers when processinghelper function calls, and does not traverse global sub-programs whenprocessing calls to global sub-programs. This means that calls tohelpers done from global sub-programs do not invalidate pointers inthe caller state. E.g. the program above is unsafe, but is notrejected by verifier.This commit fixes the omission by computing fieldbpf_subprog_info->changes_pkt_data for each sub-program before mainverification pass.changes_pkt_data should be set if:- subprogram calls helper for which bpf_helper_changes_pkt_data returns true;- subprogram calls a global function, for which bpf_subprog_info->changes_pkt_data should be set.The verifier.c:check_cfg() pass is modified to compute thisinformation. The commit relies on depth first instruction traversaldone by check_cfg() and absence of recursive function calls:- check_cfg() would eventually visit every call to subprogram S in a state when S is fully explored;- when S is fully explored: - every direct helper call within S is explored (and thus changes_pkt_data is set if needed); - every call to subprogram S1 called by S was visited with S1 fully explored (and thus S inherits changes_pkt_data from S1).The downside of such approach is that dead code elimination is nottaken into account: if a helper call inside global function is deadbecause of current configuration, verifier would conservatively assumethat the call occurs for the purpose of the changes_pkt_datacomputation.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: consider that tail calls invalidate packet pointersTail-called programs could execute any of the helpers that invalidatepacket pointers. Hence, conservatively assume that each tail callinvalidates packet pointers.Making the change in bpf_helper_changes_pkt_data() automatically makesuse of check_cfg() logic that computes 'changes_pkt_data' effect forglobal sub-programs, such that the following program could berejected: int tail_call(struct __sk_buff *sk) { bpf_tail_call_static(sk, &jmp_table, 0); return 0; } SEC("tc") int not_safe(struct __sk_buff *sk) { int *p = (void *)(long)sk->data; ... make p valid ... tail_call(sk); *p = 42; /* this is unsafe */ ... }The tc_bpf2bpf.c:subprog_tc() needs change: mark it as a function thatcan invalidate packet pointers.

Thisalso allows us to be sure we can create the "/afs/./" mountpoint too.Further, split the YFS VL record cell name maximum to be the 256 allowed bythe protocol and ignore the record retrieved by YFSVL.GetCellName if itexceeds 253.

CVE-2025-21689 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:USB: serial: quatech2: fix null-ptr-deref in qt2_process_read_urb()This patch addresses a null-ptr-deref in qt2_process_read_urb() due toan incorrect bounds check in the following: if (newport > serial->num_ports) { dev_err(&port->dev, "%s - port change to invalid port: %i\n", __func__, newport); break; }The condition doesn't account for the valid range of the serial->portbuffer, which is from 0 to serial->num_ports - 1. When newport is equalto serial->num_ports, the assignment of "port" in thefollowing code is out-of-bounds and NULL: serial_priv->current_port = newport; port = serial->port[serial_priv->current_port];The fix checks if newport is greater than or equal to serial->num_portsindicating it is out-of-bounds.

CVE-2025-21696 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm: clear uffd-wp PTE/PMD state on mremap()When mremap()ing a memory region previously registered with userfaultfd aswrite-protected but without UFFD_FEATURE_EVENT_REMAP, an inconsistency inflag clearing leads to a mismatch between the vma flags (which haveuffd-wp cleared) and the pte/pmd flags (which do not have uffd-wpcleared). This mismatch causes a subsequent mprotect(PROT_WRITE) totrigger a warning in page_table_check_pte_flags() due to setting the pteto writable while uffd-wp is still set.Fix this by always explicitly clearing the uffd-wp pte/pmd flags on anysuch mremap() so that the values are consistent with the existing clearingof VM_UFFD_WP. Be careful to clear the logical flag regardless of itsphysical form; a PTE bit, a swap PTE bit, or a PTE marker. Cover PTE,huge PMD and hugetlb paths.

This function invokes get_random_u32() to obtainrandom numbers for choosing CPUs. The batched_entropy_32 local lock and/orthe base_crng.lock spinlock in driver/char/random.c will be acquired duringthe call. In PREEMPT_RT kernel, they are both sleeping locks and so cannotbe acquired in atomic context.Fix this problem by using migrate_disable() to allow smp_processor_id() tobe reliably used without introducing atomic context. preempt_disable() isthen called after clocksource_verify_choose_cpus() but before theclocksource measurement is being run to avoid introducing unexpectedlatency.

Description: In the Linux kernel, the following vulnerability has been resolved:net: ethernet: ti: am65-cpsw: fix freeing IRQ in am65_cpsw_nuss_remove_tx_chns()When getting the IRQ we use k3_udma_glue_tx_get_irq() which returnsnegative error value on error. So not NULL check is not sufficientto deteremine if IRQ is valid. Check that IRQ is greater then zeroto ensure it is valid.There is no issue at probe time but at runtime user can invoke.set_channels which results in the following call chain.am65_cpsw_set_channels() am65_cpsw_nuss_update_tx_rx_chns() am65_cpsw_nuss_remove_tx_chns() am65_cpsw_nuss_init_tx_chns()At this point if am65_cpsw_nuss_init_tx_chns() fails due tok3_udma_glue_tx_get_irq() then tx_chn->irq will be set to anegative value.Then, at subsequent .set_channels with higher channel count wewill attempt to free an invalid IRQ in am65_cpsw_nuss_remove_tx_chns()leading to a kernel warning.The issue is present in the original commit that introduced this driver,although there, am65_cpsw_nuss_update_tx_rx_chns() existed asam65_cpsw_nuss_update_tx_chns().

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: rcar-ep: Fix incorrect variable used when calling devm_request_mem_region()The rcar_pcie_parse_outbound_ranges() uses the devm_request_mem_region()macro to request a needed resource. A string variable that lives on thestack is then used to store a dynamically computed resource name, whichis then passed on as one of the macro arguments. This can lead toundefined behavior.Depending on the current contents of the memory, the manifestations oferrors may vary. One possible output may be as follows: $ cat /proc/iomem 30000000-37ffffff : 38000000-3fffffff :Sometimes, garbage may appear after the colon.In very rare cases, if no NULL-terminator is found in memory, the systemmight crash because the string iterator will overrun which can lead toaccess of unmapped memory above the stack.Thus, fix this by replacing outbound_name with the name of the previouslyrequested resource. With the changes applied, the output will be asfollows: $ cat /proc/iomem 30000000-37ffffff : memory2 38000000-3fffffff : memory3[kwilczynski: commit log]

CVE-2025-21823 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:batman-adv: Drop unmanaged ELP metric workerThe ELP worker needs to calculate new metric values for all neighbors"reachable" over an interface. Some of the used metric sources requirelocks which might need to sleep. This sleep is incompatible with the RCUlist iterator used for the recorded neighbors. The initial approach to workaround of this problem was to queue another work item per neighbor and thenrun this in a new context.Even when this solved the RCU vs might_sleep() conflict, it has a majorproblems: Nothing was stopping the work item in case it is not neededanymore - for example because one of the related interfaces was removed orthe batman-adv module was unloaded - resulting in potential invalid memoryaccesses.Directly canceling the metric worker also has various problems:* cancel_work_sync for a to-be-deactivated interface is called with rtnl_lock held. But the code in the ELP metric worker also tries to use rtnl_lock() - which will never return in this case. This also means that cancel_work_sync would never return because it is waiting for the worker to finish.* iterating over the neighbor list for the to-be-deactivated interface is currently done using the RCU specific methods. Which means that it is possible to miss items when iterating over it without the associated spinlock - a behaviour which is acceptable for a periodic metric check but not for a cleanup routine (which must "stop" all still running workers)The better approch is to get rid of the per interface neighbor metricworker and handle everything in the interface worker. The original problemsare solved by:* creating a list of neighbors which require new metric information inside the RCU protected context, gathering the metric according to the new list outside the RCU protected context* only use rcu_trylock inside metric gathering code to avoid a deadlock when the cancel_delayed_work_sync is called in the interface removal code (which is called with the rtnl_lock held)

CVE-2025-21831 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: Avoid putting some root ports into D3 on TUXEDO Sirius Gen1commit 9d26d3a8f1b0 ("PCI: Put PCIe ports into D3 during suspend") sets thepolicy that all PCIe ports are allowed to use D3. When the system issuspended if the port is not power manageable by the platform and won't beused for wakeup via a PME this sets up the policy for these ports to gointo D3hot.This policy generally makes sense from an OSPM perspective but it leads toproblems with wakeup from suspend on the TUXEDO Sirius 16 Gen 1 with aspecific old BIOS. This manifests as a system hang.On the affected Device + BIOS combination, add a quirk for the root port ofthe problematic controller to ensure that these root ports are not put intoD3hot at suspend.This patch is based on https://lore.kernel.org/linux-pci/20230708214457.1229-2-mario.limonciello@amd.combut with the added condition both in the documentation and in the code toapply only to the TUXEDO Sirius 16 Gen 1 with a specific old BIOS and onlythe affected root ports.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: f_midi: fix MIDI Streaming descriptor lengthsWhile the MIDI jacks are configured correctly, and the MIDIStreamingendpoint descriptors are filled with the correct information,bNumEmbMIDIJack and bLength are set incorrectly in these descriptors.This does not matter when the numbers of in and out ports are equal, butwhen they differ the host will receive broken descriptors withuninitialized stack memory leaking into the descriptor for whichevervalue is smaller.The precise meaning of "in" and "out" in the port counts is not clearlydefined and can be confusing. But elsewhere the driver consistentlyuses this to match the USB meaning of IN and OUT viewed from the host,so that "in" ports send data to the host and "out" ports receive datafrom it.

Description: In the Linux kernel, the following vulnerability has been resolved:acct: perform last write from workqueueIn [1] it was reported that the acct(2) system call can be used totrigger NULL deref in cases where it is set to write to a file thattriggers an internal lookup. This can e.g., happen when pointing acc(2)to /sys/power/resume. At the point the where the write to this filehappens the calling task has already exited and called exit_fs(). Alookup will thus trigger a NULL-deref when accessing current->fs.Reorganize the code so that the the final write happens from theworkqueue but with the caller's credentials. This preserves the(strange) permission model and has almost no regression risk.This api should stop to exist though.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: avoid holding freeze_mutex during mmap operationWe use map->freeze_mutex to prevent races between map_freeze() andmemory mapping BPF map contents with writable permissions. The way wenaively do this means we'll hold freeze_mutex for entire duration of allthe mm and VMA manipulations, which is completely unnecessary. This canpotentially also lead to deadlocks, as reported by syzbot in [0].So, instead, hold freeze_mutex only during writeability checks, bump(proactively) "write active" count for the map, unlock the mutex andproceed with mmap logic. And only if something went wrong during mmaplogic, then undo that "write active" counter increment. [0] https://lore.kernel.org/bpf/678dcbc9.050a0220.303755.0066.GAE@google.com/

But that flag is meantto be used for vmalloc() and vmalloc() allocated memory is notsupposed to be used before a call to __vmalloc_node_range() which isnever called for that area.That went undetected until commit e4137f08816b ("mm, kasan, kmsan:instrument copy_from/to_kernel_nofault")The area allocated by text_area_cpu_up() is not vmalloc memory, it ismapped directly on demand when needed by map_kernel_page(). There isno VM flag corresponding to such usage, so just pass no flag. That waythe area will be unpoisonned and usable immediately.

CVE-2025-21871 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:tee: optee: Fix supplicant wait loopOP-TEE supplicant is a user-space daemon and it's possible for itbe hung or crashed or killed in the middle of processing an OP-TEERPC call. It becomes more complicated when there is incorrect shutdownordering of the supplicant process vs the OP-TEE client application whichcan eventually lead to system hang-up waiting for the closure of theclient application.Allow the client process waiting in kernel for supplicant response tobe killed rather than indefinitely waiting in an unkillable state. Also,a normal uninterruptible wait should not have resulted in the hung-taskwatchdog getting triggered, but the endless loop would.This fixes issues observed during system reboot/shutdown when supplicantgot hung for some reason or gets crashed/killed which lead to clientgetting hung in an unkillable state. It in turn lead to system being inhung up state requiring hard power off/on to recover.

Since genelink_bind() does not properlyverify whether specified eps are in fact provided by the device,in this case, an artificially manufactured one, one may get amismatch.Fix the issue by resorting to a usbnet utility functionusbnet_get_endpoints(), usually reserved for this very problem.Check for endpoints and return early before proceeding further ifany are missing.[1] Syzbot report:usb 5-1: Manufacturer: syzusb 5-1: SerialNumber: syzusb 5-1: config 0 descriptor??gl620a 5-1:0.23 usb0: register 'gl620a' at usb-dummy_hcd.0-1, ...------------[ cut here ]------------usb 5-1: BOGUS urb xfer, pipe 3 != type 1WARNING: CPU: 2 PID: 1841 at drivers/usb/core/urb.c:503 usb_submit_urb+0xe4b/0x1730 drivers/usb/core/urb.c:503Modules linked in:CPU: 2 UID: 0 PID: 1841 Comm: kworker/2:2 Not tainted 6.12.0-syzkaller-07834-g06afb0f36106 #0Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2~bpo12+1 04/01/2014Workqueue: mld mld_ifc_workRIP: 0010:usb_submit_urb+0xe4b/0x1730 drivers/usb/core/urb.c:503...Call Trace: usbnet_start_xmit+0x6be/0x2780 drivers/net/usb/usbnet.c:1467 __netdev_start_xmit include/linux/netdevice.h:5002 [inline] netdev_start_xmit include/linux/netdevice.h:5011 [inline] xmit_one net/core/dev.c:3590 [inline] dev_hard_start_xmit+0x9a/0x7b0 net/core/dev.c:3606 sch_direct_xmit+0x1ae/0xc30 net/sched/sch_generic.c:343 __dev_xmit_skb net/core/dev.c:3827 [inline] __dev_queue_xmit+0x13d4/0x43e0 net/core/dev.c:4400 dev_queue_xmit include/linux/netdevice.h:3168 [inline] neigh_resolve_output net/core/neighbour.c:1514 [inline] neigh_resolve_output+0x5bc/0x950 net/core/neighbour.c:1494 neigh_output include/net/neighbour.h:539 [inline] ip6_finish_output2+0xb1b/0x2070 net/ipv6/ip6_output.c:141 __ip6_finish_output net/ipv6/ip6_output.c:215 [inline] ip6_finish_output+0x3f9/0x1360 net/ipv6/ip6_output.c:226 NF_HOOK_COND include/linux/netfilter.h:303 [inline] ip6_output+0x1f8/0x540 net/ipv6/ip6_output.c:247 dst_output include/net/dst.h:450 [inline] NF_HOOK include/linux/netfilter.h:314 [inline] NF_HOOK include/linux/netfilter.h:308 [inline] mld_sendpack+0x9f0/0x11d0 net/ipv6/mcast.c:1819 mld_send_cr net/ipv6/mcast.c:2120 [inline] mld_ifc_work+0x740/0xca0 net/ipv6/mcast.c:2651 process_one_work+0x9c5/0x1ba0 kernel/workqueue.c:3229 process_scheduled_works kernel/workqueue.c:3310 [inline] worker_thread+0x6c8/0xf00 kernel/workqueue.c:3391 kthread+0x2c1/0x3a0 kernel/kthread.c:389 ret_from_fork+0x45/0x80 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244

Description: In the Linux kernel, the following vulnerability has been resolved:i2c: npcm: disable interrupt enable bit before devm_request_irqThe customer reports that there is a soft lockup issue related tothe i2c driver. After checking, the i2c module was doing a tx transferand the bmc machine reboots in the middle of the i2c transaction, the i2cmodule keeps the status without being reset.Due to such an i2c module status, the i2c irq handler keeps gettingtriggered since the i2c irq handler is registered in the kernel bootingprocess after the bmc machine is doing a warm rebooting.The continuous triggering is stopped by the soft lockup watchdog timer.Disable the interrupt enable bit in the i2c module before callingdevm_request_irq to fix this issue since the i2c relative status bitis read-only.Here is the soft lockup log.[ 28.176395] watchdog: BUG: soft lockup - CPU#0 stuck for 26s!

CVE-2025-21909 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: nl80211: reject cooked mode if it is set along with other flagsIt is possible to set both MONITOR_FLAG_COOK_FRAMES and MONITOR_FLAG_ACTIVEflags simultaneously on the same monitor interface from the userspace. Thiscauses a sub-interface to be created with no IEEE80211_SDATA_IN_DRIVER bitset because the monitor interface is in the cooked state and it takesprecedence over all other states. When the interface is then being deletedthe kernel calls WARN_ONCE() from check_sdata_in_driver() because of missingthat bit.Fix this by rejecting MONITOR_FLAG_COOK_FRAMES if it is set along withother flags.Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

CVE-2025-21910 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: cfg80211: regulatory: improve invalid hints checkingSyzbot keeps reporting an issue [1] that occurs when erroneous symbolssent from userspace get through into user_alpha2[] viaregulatory_hint_user() call. Such invalid regulatory hints should berejected.While a sanity check from commit 47caf685a685 ("cfg80211: regulatory:reject invalid hints") looks to be enough to deter these very cases,there is a way to get around it due to 2 reasons.1) The way isalpha() works, symbols other than latin lower andupper letters may be used to determine a country/domain.For instance, greek letters will also be considered upper/lowerletters and for such characters isalpha() will return true as well.However, ISO-3166-1 alpha2 codes should only hold latincharacters.2) While processing a user regulatory request, betweenreg_process_hint_user() and regulatory_hint_user() there happens tobe a call to queue_regulatory_request() which modifies letters inrequest->alpha2[] with toupper(). This works fine for latin symbols,less so for weird letter characters from the second part of _ctype[].Syzbot triggers a warning in is_user_regdom_saved() by first sendingover an unexpected non-latin letter that gets malformed by toupper()into a character that ends up failing isalpha() check.Prevent this by enhancing is_an_alpha2() to ensure that incomingsymbols are latin letters and nothing else.[1] Syzbot report:------------[ cut here ]------------Unexpected user alpha2: A�WARNING: CPU: 1 PID: 964 at net/wireless/reg.c:442 is_user_regdom_saved net/wireless/reg.c:440 [inline]WARNING: CPU: 1 PID: 964 at net/wireless/reg.c:442 restore_alpha2 net/wireless/reg.c:3424 [inline]WARNING: CPU: 1 PID: 964 at net/wireless/reg.c:442 restore_regulatory_settings+0x3c0/0x1e50 net/wireless/reg.c:3516Modules linked in:CPU: 1 UID: 0 PID: 964 Comm: kworker/1:2 Not tainted 6.12.0-rc5-syzkaller-00044-gc1e939a21eb1 #0Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 09/13/2024Workqueue: events_power_efficient crda_timeout_workRIP: 0010:is_user_regdom_saved net/wireless/reg.c:440 [inline]RIP: 0010:restore_alpha2 net/wireless/reg.c:3424 [inline]RIP: 0010:restore_regulatory_settings+0x3c0/0x1e50 net/wireless/reg.c:3516...Call Trace: crda_timeout_work+0x27/0x50 net/wireless/reg.c:542 process_one_work kernel/workqueue.c:3229 [inline] process_scheduled_works+0xa65/0x1850 kernel/workqueue.c:3310 worker_thread+0x870/0xd30 kernel/workqueue.c:3391 kthread+0x2f2/0x390 kernel/kthread.c:389 ret_from_fork+0x4d/0x80 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244

CVE-2025-21919 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:sched/fair: Fix potential memory corruption in child_cfs_rq_on_listchild_cfs_rq_on_list attempts to convert a 'prev' pointer to a cfs_rq.This 'prev' pointer can originate from struct rq's leaf_cfs_rq_list,making the conversion invalid and potentially leading to memorycorruption. Depending on the relative positions of leaf_cfs_rq_list andthe task group (tg) pointer within the struct, this can cause a memoryfault or access garbage data.The issue arises in list_add_leaf_cfs_rq, where bothcfs_rq->leaf_cfs_rq_list and rq->leaf_cfs_rq_list are added to the sameleaf list. Also, rq->tmp_alone_branch can be set to rq->leaf_cfs_rq_list.This adds a check `if (prev == &rq->leaf_cfs_rq_list)` after the mainconditional in child_cfs_rq_on_list. This ensures that the container_ofoperation will convert a correct cfs_rq struct.This check is sufficient because only cfs_rqs on the same CPU are addedto the list, so verifying the 'prev' pointer against the current rq's listhead is enough.Fixes a potential memory corruption issue that due to current structlayout might not be manifesting as a crash but could lead to unpredictablebehavior when the layout changes.

CVE-2025-21920 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:vlan: enforce underlying device typeCurrently, VLAN devices can be created on top of non-ethernet devices.Besides the fact that it doesn't make much sense, this also causes abug which leaks the address of a kernel function to usermode.When creating a VLAN device, we initialize GARP (garp_init_applicant)and MRP (mrp_init_applicant) for the underlying device.As part of the initialization process, we add the multicast address ofeach applicant to the underlying device, by calling dev_mc_add.__dev_mc_add uses dev->addr_len to determine the length of the newmulticast address.This causes an out-of-bounds read if dev->addr_len is greater than 6,since the multicast addresses provided by GARP and MRP are only 6bytes long.This behaviour can be reproduced using the following commands:ip tunnel add gretest mode ip6gre local ::1 remote ::2 dev loip l set up dev gretestip link add link gretest name vlantest type vlan id 100Then, the following command will display the address of garp_pdu_rcv:ip maddr show | grep 01:80:c2:00:00:21Fix the bug by enforcing the type of the underlying device during VLANdevice initialization.

Description: In the Linux kernel, the following vulnerability has been resolved:HID: intel-ish-hid: Fix use-after-free issue in ishtp_hid_remove()The system can experience a random crash a few minutes after the driver isremoved. This issue occurs due to improper handling of memory freeing inthe ishtp_hid_remove() function.The function currently frees the `driver_data` directly within the loopthat destroys the HID devices, which can lead to accessing freed memory.Specifically, `hid_destroy_device()` uses `driver_data` when it calls`hid_ishtp_set_feature()` to power off the sensor, so freeing`driver_data` beforehand can result in accessing invalid memory.This patch resolves the issue by storing the `driver_data` in a temporaryvariable before calling `hid_destroy_device()`, and then freeing the`driver_data` after the device is destroyed.

However,it does not make appleir_probe() fail and lets the event callback to becalled without the associated input device.Thus, add a check for the HID_CLAIMED_INPUT flag and leave the event hookearly if the driver didn't claim any input_dev for some reason. Moreover,some other hid drivers accessing input_dev in their event callbacks do havesimilar checks, too.Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Description: In the Linux kernel, the following vulnerability has been resolved:drivers: virt: acrn: hsm: Use kzalloc to avoid info leak in pmcmd_ioctlIn the "pmcmd_ioctl" function, three memory objects allocated bykmalloc are initialized by "hcall_get_cpu_state", which are thencopied to user space. The initializer is indeed implemented in"acrn_hypercall2" (arch/x86/include/asm/acrn.h). There is a risk ofinformation leakage due to uninitialized bytes.

CVE-2025-21951 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bus: mhi: host: pci_generic: Use pci_try_reset_function() to avoid deadlockThere are multiple places from where the recovery work gets scheduledasynchronously. Also, there are multiple places where the caller waitssynchronously for the recovery to be completed. One such place is duringthe PM shutdown() callback.If the device is not alive during recovery_work, it will try to reset thedevice using pci_reset_function(). This function internally will take thedevice_lock() first before resetting the device. By this time, if the lockhas already been acquired, then recovery_work will get stalled whilewaiting for the lock. And if the lock was already acquired by the callerwhich waits for the recovery_work to be completed, it will lead todeadlock.This is what happened on the X1E80100 CRD device when the device diedbefore shutdown() callback. Driver core calls the driver's shutdown()callback while holding the device_lock() leading to deadlock.And this deadlock scenario can occur on other paths as well, like duringthe PM suspend() callback, where the driver core would hold thedevice_lock() before calling driver's suspend() callback. And if therecovery_work was already started, it could lead to deadlock. This is alsoobserved on the X1E80100 CRD.So to fix both issues, use pci_try_reset_function() in recovery_work. Thisfunction first checks for the availability of the device_lock() beforetrying to reset the device. If the lock is available, it will acquire itand reset the device. Otherwise, it will return -EAGAIN. If that happens,recovery_work will fail with the error message "Recovery failed" as notmuch could be done.

CVE-2025-21953 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: mana: cleanup mana struct after debugfs_remove()When on a MANA VM hibernation is triggered, as part of hibernate_snapshot(),mana_gd_suspend() and mana_gd_resume() are called. If during thismana_gd_resume(), a failure occurs with HWC creation, mana_port_debugfspointer does not get reinitialized and ends up pointing to older,cleaned-up dentry.Further in the hibernation path, as part of power_down(), mana_gd_shutdown()is triggered. This call, unaware of the failures in resume, tries to cleanupthe already cleaned up mana_port_debugfs value and hits the following bug:[ 191.359296] mana 7870:00:00.0: Shutdown was called[ 191.359918] BUG: kernel NULL pointer dereference, address: 0000000000000098[ 191.360584] #PF: supervisor write access in kernel mode[ 191.361125] #PF: error_code(0x0002) - not-present page[ 191.361727] PGD 1080ea067 P4D 0[ 191.362172] Oops: Oops: 0002 [#1] SMP NOPTI[ 191.362606] CPU: 11 UID: 0 PID: 1674 Comm: bash Not tainted 6.14.0-rc5+ #2[ 191.363292] Hardware name: Microsoft Corporation Virtual Machine/Virtual Machine, BIOS Hyper-V UEFI Release v4.1 11/21/2024[ 191.364124] RIP: 0010:down_write+0x19/0x50[ 191.364537] Code: 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 0f 1f 44 00 00 55 48 89 e5 53 48 89 fb e8 de cd ff ff 31 c0 ba 01 00 00 00 48 0f b1 13 75 16 65 48 8b 05 88 24 4c 6a 48 89 43 08 48 8b 5d[ 191.365867] RSP: 0000:ff45fbe0c1c037b8 EFLAGS: 00010246[ 191.366350] RAX: 0000000000000000 RBX: 0000000000000098 RCX: ffffff8100000000[ 191.366951] RDX: 0000000000000001 RSI: 0000000000000064 RDI: 0000000000000098[ 191.367600] RBP: ff45fbe0c1c037c0 R08: 0000000000000000 R09: 0000000000000001[ 191.368225] R10: ff45fbe0d2b01000 R11: 0000000000000008 R12: 0000000000000000[ 191.368874] R13: 000000000000000b R14: ff43dc27509d67c0 R15: 0000000000000020[ 191.369549] FS: 00007dbc5001e740(0000) GS:ff43dc663f380000(0000) knlGS:0000000000000000[ 191.370213] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 191.370830] CR2: 0000000000000098 CR3: 0000000168e8e002 CR4: 0000000000b73ef0[ 191.371557] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 191.372192] DR3: 0000000000000000 DR6: 00000000fffe07f0 DR7: 0000000000000400[ 191.372906] Call Trace:[ 191.373262] [ 191.373621] ? show_regs+0x64/0x70[ 191.374040] ? __die+0x24/0x70[ 191.374468] ? page_fault_oops+0x290/0x5b0[ 191.374875] ? do_user_addr_fault+0x448/0x800[ 191.375357] ? exc_page_fault+0x7a/0x160[ 191.375971] ? asm_exc_page_fault+0x27/0x30[ 191.376416] ? down_write+0x19/0x50[ 191.376832] ? down_write+0x12/0x50[ 191.377232] simple_recursive_removal+0x4a/0x2a0[ 191.377679] ? __pfx_remove_one+0x10/0x10[ 191.378088] debugfs_remove+0x44/0x70[ 191.378530] mana_detach+0x17c/0x4f0[ 191.378950] ? __flush_work+0x1e2/0x3b0[ 191.379362] ? __cond_resched+0x1a/0x50[ 191.379787] mana_remove+0xf2/0x1a0[ 191.380193] mana_gd_shutdown+0x3b/0x70[ 191.380642] pci_device_shutdown+0x3a/0x80[ 191.381063] device_shutdown+0x13e/0x230[ 191.381480] kernel_power_off+0x35/0x80[ 191.381890] hibernate+0x3c6/0x470[ 191.382312] state_store+0xcb/0xd0[ 191.382734] kobj_attr_store+0x12/0x30[ 191.383211] sysfs_kf_write+0x3e/0x50[ 191.383640] kernfs_fop_write_iter+0x140/0x1d0[ 191.384106] vfs_write+0x271/0x440[ 191.384521] ksys_write+0x72/0xf0[ 191.384924] __x64_sys_write+0x19/0x20[ 191.385313] x64_sys_call+0x2b0/0x20b0[ 191.385736] do_syscall_64+0x79/0x150[ 191.386146] ? __mod_memcg_lruvec_state+0xe7/0x240[ 191.386676] ? __lruvec_stat_mod_folio+0x79/0xb0[ 191.387124] ? __pfx_lru_add+0x10/0x10[ 191.387515] ? queued_spin_unlock+0x9/0x10[ 191.387937] ? do_anonymous_page+0x33c/0xa00[ 191.388374] ? __handle_mm_fault+0xcf3/0x1210[ 191.388805] ? __count_memcg_events+0xbe/0x180[ 191.389235] ? handle_mm_fault+0xae/0x300[ 19---truncated---

CVE-2025-21970 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5: Bridge, fix the crash caused by LAG state checkWhen removing LAG device from bridge, NETDEV_CHANGEUPPER event istriggered. Driver finds the lower devices (PFs) to flush all theoffloaded entries. And mlx5_lag_is_shared_fdb is checked, it returnsfalse if one of PF is unloaded. In such case,mlx5_esw_bridge_lag_rep_get() and its caller return NULL, instead ofthe alive PF, and the flush is skipped.Besides, the bridge fdb entry's lastuse is updated in mlx5 bridgeevent handler. But this SWITCHDEV_FDB_ADD_TO_BRIDGE event can beignored in this case because the upper interface for bond is deleted,and the entry will never be aged because lastuse is never updated.To make things worse, as the entry is alive, mlx5 bridge workqueuekeeps sending that event, which is then handled by kernel bridgenotifier. It causes the following crash when accessing the passed bondnetdev which is already destroyed.To fix this issue, remove such checks. LAG state is already checked incommit 15f8f168952f ("net/mlx5: Bridge, verify LAG state when addingbond to bridge"), driver still need to skip offload if LAG becomesinvalid state after initialization.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/hyperv: Fix address space leak when Hyper-V DRM device is removedWhen a Hyper-V DRM device is probed, the driver allocates MMIO space forthe vram, and maps it cacheable. If the device removed, or in the errorpath for device probing, the MMIO space is released but no unmap is done.Consequently the kernel address space for the mapping is leaked.Fix this by adding iounmap() calls in the device removal path, and in theerror path during device probing.

This, in turn, callsgred_offload, where memset could receive a NULL pointer as input,potentially leading to a kernel crash.When table->opt is NULL in gred_init(), gred_change_table_def()is not called yet, so it is not necessary to call ->ndo_setup_tc()in gred_offload().

Description: In the Linux kernel, the following vulnerability has been resolved:x86/microcode/AMD: Fix out-of-bounds on systems with CPU-less NUMA nodesCurrently, load_microcode_amd() iterates over all NUMA nodes, retrieves theirCPU masks and unconditionally accesses per-CPU data for the first CPU of eachmask.According to Documentation/admin-guide/mm/numaperf.rst: "Some memory may share the same node as a CPU, and others are provided as memory only nodes."Therefore, some node CPU masks may be empty and wouldn't have a "first CPU".On a machine with far memory (and therefore CPU-less NUMA nodes):- cpumask_of_node(nid) is 0- cpumask_first(0) is CONFIG_NR_CPUS- cpu_data(CONFIG_NR_CPUS) accesses the cpu_info per-CPU array at an index that is 1 out of boundsThis does not have any security implications since flashing microcode isa privileged operation but I believe this has reliability implications bypotentially corrupting memory while flashing a microcode update.When booting with CONFIG_UBSAN_BOUNDS=y on an AMD machine that flashesa microcode update. I get the following splat: UBSAN: array-index-out-of-bounds in arch/x86/kernel/cpu/microcode/amd.c:X:Y index 512 is out of range for type 'unsigned long[512]' [...] Call Trace: dump_stack __ubsan_handle_out_of_bounds load_microcode_amd request_microcode_amd reload_store kernfs_fop_write_iter vfs_write ksys_write do_syscall_64 entry_SYSCALL_64_after_hwframeChange the loop to go over only NUMA nodes which have CPUs before determiningwhether the first CPU on the respective node needs microcode update.

Description: In the Linux kernel, the following vulnerability has been resolved:can: ucan: fix out of bound read in strscpy() sourceCommit 7fdaf8966aae ("can: ucan: use strscpy() to instead of strncpy()")unintentionally introduced a one byte out of bound read on strscpy()'ssource argument (which is kind of ironic knowing that strscpy() is meantto be a more secure alternative :)).Let's consider below buffers: dest[len + 1]; /* will be NUL terminated */ src[len]; /* may not be NUL terminated */When doing: strncpy(dest, src, len); dest[len] = '\0';strncpy() will read up to len bytes from src.On the other hand: strscpy(dest, src, len + 1);will read up to len + 1 bytes from src, that is to say, an out of boundread of one byte will occur on src if it is not NUL terminated. Notethat the src[len] byte is never copied, but strscpy() still needs toread it to check whether a truncation occurred or not.This exact pattern happened in ucan.The root cause is that the source is not NUL terminated. Instead ofdoing a copy in a local buffer, directly NUL terminate it as soon asusb_control_msg() returns. With this, the local firmware_str[] variablecan be removed.On top of this do a couple refactors: - ucan_ctl_payload->raw is only used for the firmware string, so rename it to ucan_ctl_payload->fw_str and change its type from u8 to char. - ucan_device_request_in() is only used to retrieve the firmware string, so rename it to ucan_get_fw_str() and refactor it to make it directly handle all the string termination logic.

If these are NULL,the entry will be passd to eg_cache_put() as parameter andit is referenced by entry->use code in it.kasan log:[ 3.316691] Oops: general protection fault, probably for non-canonical address 0xdffffc0000000006:I[ 3.317568] KASAN: null-ptr-deref in range [0x0000000000000030-0x0000000000000037][ 3.318188] CPU: 3 UID: 0 PID: 79 Comm: ex Not tainted 6.14.0-rc2 #102[ 3.318601] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014[ 3.319298] RIP: 0010:eg_cache_remove_entry+0xa5/0x470[ 3.319677] Code: c1 f7 6e fd 48 c7 c7 00 7e 38 b2 e8 95 64 54 fd 48 c7 c7 40 7e 38 b2 48 89 ee e80[ 3.321220] RSP: 0018:ffff88800583f8a8 EFLAGS: 00010006[ 3.321596] RAX: 0000000000000006 RBX: ffff888005989000 RCX: ffffffffaecc2d8e[ 3.322112] RDX: 0000000000000000 RSI: 0000000000000004 RDI: 0000000000000030[ 3.322643] RBP: 0000000000000000 R08: 0000000000000000 R09: fffffbfff6558b88[ 3.323181] R10: 0000000000000003 R11: 203a207972746e65 R12: 1ffff11000b07f15[ 3.323707] R13: dffffc0000000000 R14: ffff888005989000 R15: ffff888005989068[ 3.324185] FS: 000000001b6313c0(0000) GS:ffff88806d380000(0000) knlGS:0000000000000000[ 3.325042] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 3.325545] CR2: 00000000004b4b40 CR3: 000000000248e000 CR4: 00000000000006f0[ 3.326430] Call Trace:[ 3.326725] [ 3.326927] ? die_addr+0x3c/0xa0[ 3.327330] ? exc_general_protection+0x161/0x2a0[ 3.327662] ? asm_exc_general_protection+0x26/0x30[ 3.328214] ? vprintk_emit+0x15e/0x420[ 3.328543] ? eg_cache_remove_entry+0xa5/0x470[ 3.328910] ? eg_cache_remove_entry+0x9a/0x470[ 3.329294] ? __pfx_eg_cache_remove_entry+0x10/0x10[ 3.329664] ? console_unlock+0x107/0x1d0[ 3.329946] ? __pfx_console_unlock+0x10/0x10[ 3.330283] ? do_syscall_64+0xa6/0x1a0[ 3.330584] ? entry_SYSCALL_64_after_hwframe+0x47/0x7f[ 3.331090] ? __pfx_prb_read_valid+0x10/0x10[ 3.331395] ? down_trylock+0x52/0x80[ 3.331703] ? vprintk_emit+0x15e/0x420[ 3.331986] ? __pfx_vprintk_emit+0x10/0x10[ 3.332279] ? down_trylock+0x52/0x80[ 3.332527] ? _printk+0xbf/0x100[ 3.332762] ? __pfx__printk+0x10/0x10[ 3.333007] ? _raw_write_lock_irq+0x81/0xe0[ 3.333284] ? __pfx__raw_write_lock_irq+0x10/0x10[ 3.333614] msg_from_mpoad+0x1185/0x2750[ 3.333893] ? __build_skb_around+0x27b/0x3a0[ 3.334183] ? __pfx_msg_from_mpoad+0x10/0x10[ 3.334501] ? __alloc_skb+0x1c0/0x310[ 3.334809] ? __pfx___alloc_skb+0x10/0x10[ 3.335283] ? _raw_spin_lock+0xe0/0xe0[ 3.335632] ? finish_wait+0x8d/0x1e0[ 3.335975] vcc_sendmsg+0x684/0xba0[ 3.336250] ? __pfx_vcc_sendmsg+0x10/0x10[ 3.336587] ? __pfx_autoremove_wake_function+0x10/0x10[ 3.337056] ? fdget+0x176/0x3e0[ 3.337348] __sys_sendto+0x4a2/0x510[ 3.337663] ? __pfx___sys_sendto+0x10/0x10[ 3.337969] ? ioctl_has_perm.constprop.0.isra.0+0x284/0x400[ 3.338364] ? sock_ioctl+0x1bb/0x5a0[ 3.338653] ? __rseq_handle_notify_resume+0x825/0xd20[ 3.339017] ? __pfx_sock_ioctl+0x10/0x10[ 3.339316] ? __pfx___rseq_handle_notify_resume+0x10/0x10[ 3.339727] ? selinux_file_ioctl+0xa4/0x260[ 3.340166] __x64_sys_sendto+0xe0/0x1c0[ 3.340526] ? syscall_exit_to_user_mode+0x123/0x140[ 3.340898] do_syscall_64+0xa6/0x1a0[ 3.341170] entry_SYSCALL_64_after_hwframe+0x77/0x7f[ 3.341533] RIP: 0033:0x44a380[ 3.341757] Code: 0f 1f 84 00 00 00 00 00 66 90 f3 0f 1e fa 41 89 ca 64 8b 04 25 18 00 00 00 85 c00[ ---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:acpi: nfit: fix narrowing conversion in acpi_nfit_ctlSyzkaller has reported a warning in to_nfit_bus_uuid(): "only secondarybus families can be translated". This warning is emited if the argumentis equal to NVDIMM_BUS_FAMILY_NFIT == 0. Function acpi_nfit_ctl() firstverifies that a user-provided value call_pkg->nd_family of type u64 isnot equal to 0. Then the value is converted to int, and only after thatis compared to NVDIMM_BUS_FAMILY_MAX. This can lead to passing an invalidargument to acpi_nfit_ctl(), if call_pkg->nd_family is non-zero, whilethe lower 32 bits are zero.Furthermore, it is best to return EINVAL immediately upon seeing theinvalid user input. The WARNING is insufficient to prevent furtherundefined behavior based on other invalid user input.All checks of the input value should be applied to the original variablecall_pkg->nd_family.[iweiny: update commit message]

Description: In the Linux kernel, the following vulnerability has been resolved:spufs: fix gang directory lifetimesprior to "[POWERPC] spufs: Fix gang destroy leaks" we used to havea problem with gang lifetimes - creation of a gang returns openedgang directory, which normally gets removed when that gets closed,but if somebody has created a context belonging to that gang andkept it alive until the gang got closed, removal failed and weended up with a leak.Unfortunately, it had been fixed the wrong way. Dentry of gangdirectory was no longer pinned, and rmdir on close was gone.One problem was that failure of open kept calling simple_rmdir()as cleanup, which meant an unbalanced dput(). Another bug wasin the success case - gang creation incremented link count onroot directory, but that was no longer undone when gang gotdestroyed.Fix consists of * reverting the commit in question * adding a counter to gang, protected by ->i_rwsemof gang directory inode. * having it set to 1 at creation time, droppedin both spufs_dir_close() and spufs_gang_close() and bumpedin spufs_create_context(), provided that it's not 0. * using simple_recursive_removal() to take the gangdirectory out when counter reaches zero.

CVE-2025-22077 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:Revert "smb: client: fix TCP timers deadlock after rmmod"This reverts commit e9f2517a3e18a54a3943c098d2226b245d488801.Commit e9f2517a3e18 ("smb: client: fix TCP timers deadlock afterrmmod") is intended to fix a null-ptr-deref in LOCKDEP, which ismentioned as CVE-2024-54680, but is actually did not fix anything;The issue can be reproduced on top of it. [0]Also, it reverted the change by commit ef7134c7fc48 ("smb: client:Fix use-after-free of network namespace.") and introduced a realissue by reviving the kernel TCP socket.When a reconnect happens for a CIFS connection, the socket statetransitions to FIN_WAIT_1. Then, inet_csk_clear_xmit_timers_sync()in tcp_close() stops all timers for the socket.If an incoming FIN packet is lost, the socket will stay at FIN_WAIT_1forever, and such sockets could be leaked up to net.ipv4.tcp_max_orphans.Usually, FIN can be retransmitted by the peer, but if the peer abortsthe connection, the issue comes into reality.I warned about this privately by pointing out the exact report [1],but the bogus fix was finally merged.So, we should not stop the timers to finally kill the connection onour side in that case, meaning we must not use a kernel socket forTCP whose sk->sk_net_refcnt is 0.The kernel socket does not have a reference to its netns to make itpossible to tear down netns without cleaning up every resource in it.For example, tunnel devices use a UDP socket internally, but we candestroy netns without removing such devices and let it completeduring exit. Otherwise, netns would be leaked when the last applicationdied.However, this is problematic for TCP sockets because TCP has timers toclose the connection gracefully even after the socket is close()d. Thelifetime of the socket and its netns is different from the lifetime ofthe underlying connection.If the socket user does not maintain the netns lifetime, the timer couldbe fired after the socket is close()d and its netns is freed up, resultingin use-after-free.Actually, we have seen so many similar issues and converted such socketsto have a reference to netns.That's why I converted the CIFS client socket to have a reference tonetns (sk->sk_net_refcnt == 1), which is somehow mentioned as out-of-scopeof CIFS and technically wrong in e9f2517a3e18, but **is in-scope and rightfix**.Regarding the LOCKDEP issue, we can prevent the module unload bybumping the module refcount when switching the LOCKDDEP key insock_lock_init_class_and_name(). [2]For a while, let's revert the bogus fix.Note that now we can use sk_net_refcnt_upgrade() for the socketconversion, but I'll do so later separately to make backport easy.

CVE-2025-22083 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:vhost-scsi: Fix handling of multiple calls to vhost_scsi_set_endpointIf vhost_scsi_set_endpoint is called multiple times without avhost_scsi_clear_endpoint between them, we can hit multiple bugsfound by Haoran Zhang:1. Use-after-free when no tpgs are found:This fixes a use after free that occurs when vhost_scsi_set_endpoint iscalled more than once and calls after the first call do not find anytpgs to add to the vs_tpg. When vhost_scsi_set_endpoint first findstpgs to add to the vs_tpg array match=true, so we will do:vhost_vq_set_backend(vq, vs_tpg);...kfree(vs->vs_tpg);vs->vs_tpg = vs_tpg;If vhost_scsi_set_endpoint is called again and no tpgs are foundmatch=false so we skip the vhost_vq_set_backend call leaving thepointer to the vs_tpg we then free via:kfree(vs->vs_tpg);vs->vs_tpg = vs_tpg;If a scsi request is then sent we do:vhost_scsi_handle_vq -> vhost_scsi_get_req -> vhost_vq_get_backendwhich sees the vs_tpg we just did a kfree on.2. Tpg dir removal hang:This patch fixes an issue where we cannot remove a LIO/target layertpg (and structs above it like the target) dir due to the refcountdropping to -1.The problem is that if vhost_scsi_set_endpoint detects a tpg is alreadyin the vs->vs_tpg array or if the tpg has been removed sotarget_depend_item fails, the undepend goto handler will dotarget_undepend_item on all tpgs in the vs_tpg array dropping theirrefcount to 0. At this time vs_tpg contains both the tpgs we have addedin the current vhost_scsi_set_endpoint call as well as tpgs we added inprevious calls which are also in vs->vs_tpg.Later, when vhost_scsi_clear_endpoint runs it will dotarget_undepend_item on all the tpgs in the vs->vs_tpg which will droptheir refcount to -1. Userspace will then not be able to remove the tpgand will hang when it tries to do rmdir on the tpg dir.3. Tpg leak:This fixes a bug where we can leak tpgs and cause them to beun-removable because the target name is overwritten whenvhost_scsi_set_endpoint is called multiple times but with differenttarget names.The bug occurs if a user has called VHOST_SCSI_SET_ENDPOINT and setupa vhost-scsi device to target/tpg mapping, then callsVHOST_SCSI_SET_ENDPOINT again with a new target name that has tpgs wehaven't seen before (target1 has tpg1 but target2 has tpg2). When thishappens we don't teardown the old target tpg mapping and just overwritethe target name and the vs->vs_tpg array. Later when we dovhost_scsi_clear_endpoint, we are passed in either target1 or target2'sname and we will only match that target's tpgs when we loop over thevs->vs_tpg. We will then return from the function without doingtarget_undepend_item on the tpgs.Because of all these bugs, it looks like being able to callvhost_scsi_set_endpoint multiple times was never supported. The majoruser, QEMU, already has checks to prevent this use case. So to fix theissues, this patch prevents vhost_scsi_set_endpoint from being calledif it's already successfully added tpgs. To add, remove or change thetpg config or target name, you must do a vhost_scsi_clear_endpointfirst.

CVE-2025-22090 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:x86/mm/pat: Fix VM_PAT handling when fork() fails in copy_page_range()If track_pfn_copy() fails, we already added the dst VMA to the mapletree. As fork() fails, we'll cleanup the maple tree, and stumble overthe dst VMA for which we neither performed any reservation nor copiedany page tables.Consequently untrack_pfn() will see VM_PAT and try obtaining thePAT information from the page table -- which fails because the pagetable was not copied.The easiest fix would be to simply clear the VM_PAT flag of the dst VMAif track_pfn_copy() fails. However, the whole thing is about "simply"clearing the VM_PAT flag is shaky as well: if we passed track_pfn_copy()and performed a reservation, but copying the page tables fails, we'llsimply clear the VM_PAT flag, not properly undoing the reservation ...which is also wrong.So let's fix it properly: set the VM_PAT flag only if the reservationsucceeded (leaving it clear initially), and undo the reservation ifanything goes wrong while copying the page tables: clearing the VM_PATflag after undoing the reservation.Note that any copied page table entries will get zapped when the VMA willget removed later, after copy_page_range() succeeded; as VM_PAT is not setthen, we won't try cleaning VM_PAT up once more and untrack_pfn() will behappy. Note that leaving these page tables in place without a reservationis not a problem, as we are aborting fork(); this process will never run.A reproducer can trigger this usually at the first try: https://gitlab.com/davidhildenbrand/scratchspace/-/raw/main/reproducers/pat_fork.c WARNING: CPU: 26 PID: 11650 at arch/x86/mm/pat/memtype.c:983 get_pat_info+0xf6/0x110 Modules linked in: ...

Description: In the Linux kernel, the following vulnerability has been resolved:dlm: prevent NPD when writing a positive value to event_donedo_uevent returns the value written to event_done. In case it is apositive value, new_lockspace would undo all the work, and lockspacewould not be set. __dlm_new_lockspace, however, would treat thatpositive value as a success due to commit 8511a2728ab8 ("dlm: fix usecount with multiple joins").Down the line, device_create_lockspace would pass that NULL lockspace todlm_find_lockspace_local, leading to a NULL pointer dereference.Treating such positive values as successes prevents the problem. Giventhis has been broken for so long, this is unlikely to break userspaceexpectations.

CVE-2025-23142 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:sctp: detect and prevent references to a freed transport in sendmsgsctp_sendmsg() re-uses associations and transports when possible bydoing a lookup based on the socket endpoint and the message destinationaddress, and then sctp_sendmsg_to_asoc() sets the selected transport inall the message chunks to be sent.There's a possible race condition if another thread triggers the removalof that selected transport, for instance, by explicitly unbinding anaddress with setsockopt(SCTP_SOCKOPT_BINDX_REM), after the chunks havebeen set up and before the message is sent. This can happen if the sendbuffer is full, during the period when the sender thread temporarilyreleases the socket lock in sctp_wait_for_sndbuf().This causes the access to the transport data insctp_outq_select_transport(), when the association outqueue is flushed,to result in a use-after-free read.This change avoids this scenario by having sctp_transport_free() signalthe freeing of the transport, tagging it as "dead". In order to do this,the patch restores the "dead" bit in struct sctp_transport, which wasremoved incommit 47faa1e4c50e ("sctp: remove the dead field of sctp_transport").Then, in the scenario where the sender thread has released the socketlock in sctp_wait_for_sndbuf(), the bit is checked again afterre-acquiring the socket lock to detect the deletion. This is done whileholding a reference to the transport to prevent it from being freed inthe process.If the transport was deleted while the socket lock was relinquished,sctp_sendmsg_to_asoc() will return -EAGAIN to let userspace retry thesend.The bug was found by a private syzbot instance (see the error report [1]and the C reproducer that triggers it [2]).

CVE-2025-23143 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: Fix null-ptr-deref by sock_lock_init_class_and_name() and rmmod.When I ran the repro [0] and waited a few seconds, I observed twoLOCKDEP splats: a warning immediately followed by a null-ptr-deref. [1]Reproduction Steps: 1) Mount CIFS 2) Add an iptables rule to drop incoming FIN packets for CIFS 3) Unmount CIFS 4) Unload the CIFS module 5) Remove the iptables ruleAt step 3), the CIFS module calls sock_release() for the underlyingTCP socket, and it returns quickly. However, the socket remains inFIN_WAIT_1 because incoming FIN packets are dropped.At this point, the module's refcnt is 0 while the socket is stillalive, so the following rmmod command succeeds. # ss -tan State Recv-Q Send-Q Local Address:Port Peer Address:Port FIN-WAIT-1 0 477 10.0.2.15:51062 10.0.0.137:445 # lsmod | grep cifs cifs 1159168 0This highlights a discrepancy between the lifetime of the CIFS moduleand the underlying TCP socket. Even after CIFS calls sock_release()and it returns, the TCP socket does not die immediately in order toclose the connection gracefully.While this is generally fine, it causes an issue with LOCKDEP becauseCIFS assigns a different lock class to the TCP socket's sk->sk_lockusing sock_lock_init_class_and_name().Once an incoming packet is processed for the socket or a timer fires,sk->sk_lock is acquired.Then, LOCKDEP checks the lock context in check_wait_context(), wherehlock_class() is called to retrieve the lock class. However, sincethe module has already been unloaded, hlock_class() logs a warningand returns NULL, triggering the null-ptr-deref.If LOCKDEP is enabled, we must ensure that a module callingsock_lock_init_class_and_name() (CIFS, NFS, etc) cannot be unloadedwhile such a socket is still alive to prevent this issue.Let's hold the module reference in sock_lock_init_class_and_name()and release it when the socket is freed in sk_prot_free().Note that sock_lock_init() clears sk->sk_owner for svc_create_socket()that calls sock_lock_init_class_and_name() for a listening socket,which clones a socket by sk_clone_lock() without GFP_ZERO.[0]:CIFS_SERVER="10.0.0.137"CIFS_PATH="//${CIFS_SERVER}/Users/Administrator/Desktop/CIFS_TEST"DEV="enp0s3"CRED="/root/WindowsCredential.txt"MNT=$(mktemp -d /tmp/XXXXXX)mount -t cifs ${CIFS_PATH} ${MNT} -o vers=3.0,credentials=${CRED},cache=none,echo_interval=1iptables -A INPUT -s ${CIFS_SERVER} -j DROPfor i in $(seq 10);do umount ${MNT} rmmod cifs sleep 1donerm -r ${MNT}iptables -D INPUT -s ${CIFS_SERVER} -j DROP[1]:DEBUG_LOCKS_WARN_ON(1)WARNING: CPU: 10 PID: 0 at kernel/locking/lockdep.c:234 hlock_class (kernel/locking/lockdep.c:234 kernel/locking/lockdep.c:223)Modules linked in: cifs_arc4 nls_ucs2_utils cifs_md4 [last unloaded: cifs]CPU: 10 UID: 0 PID: 0 Comm: swapper/10 Not tainted 6.14.0 #36Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.0-0-gd239552ce722-prebuilt.qemu.org 04/01/2014RIP: 0010:hlock_class (kernel/locking/lockdep.c:234 kernel/locking/lockdep.c:223)...Call Trace: __lock_acquire (kernel/locking/lockdep.c:4853 kernel/locking/lockdep.c:5178) lock_acquire (kernel/locking/lockdep.c:469 kernel/locking/lockdep.c:5853 kernel/locking/lockdep.c:5816) _raw_spin_lock_nested (kernel/locking/spinlock.c:379) tcp_v4_rcv (./include/linux/skbuff.h:1678 ./include/net/tcp.h:2547 net/ipv4/tcp_ipv4.c:2350)...BUG: kernel NULL pointer dereference, address: 00000000000000c4 PF: supervisor read access in kernel mode PF: error_code(0x0000) - not-present pagePGD 0Oops: Oops: 0000 [#1] PREEMPT SMP NOPTICPU: 10 UID: 0 PID: 0 Comm: swapper/10 Tainted: G W 6.14.0 #36Tainted: [W]=WARNHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.0-0-gd239552ce722-prebuilt.qemu.org 04/01/2014RIP: 0010:__lock_acquire (kernel/---truncated---

CVE-2025-23147 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:i3c: Add NULL pointer check in i3c_master_queue_ibi()The I3C master driver may receive an IBI from a target device that has notbeen probed yet. In such cases, the master calls `i3c_master_queue_ibi()`to queue an IBI work task, leading to "Unable to handle kernel read fromunreadable memory" and resulting in a kernel panic.Typical IBI handling flow:1. The I3C master scans target devices and probes their respective drivers.2. The target device driver calls `i3c_device_request_ibi()` to enable IBI and assigns `dev->ibi = ibi`.3. The I3C master receives an IBI from the target device and calls `i3c_master_queue_ibi()` to queue the target device driver's IBI handler task.However, since target device events are asynchronous to the I3C probesequence, step 3 may occur before step 2, causing `dev->ibi` to be `NULL`,leading to a kernel panic.Add a NULL pointer check in `i3c_master_queue_ibi()` to prevent accessingan uninitialized `dev->ibi`, ensuring stability.

The reference count is 0, so the dma_buf is destroyed, which in turn decrements the corresponding amdgpu_bo reference count to 0, and the amdgpu_bo is destroyed - calling drm_gem_object_release then dma_resv_fini (which destroys the reservation object), then finally freeing the amdgpu_bo.- nouveau_bo obj->bo.base.resv is now a dangling pointer to the memory formerly allocated to the amdgpu_bo.- nouveau_gem_object_del calls ttm_bo_put(&nvbo->bo) which calls ttm_bo_release, which schedules ttm_bo_delayed_delete.- ttm_bo_delayed_delete runs and dereferences the dangling resv pointer, resulting in a general protection fault.Fix this by moving the drm_prime_gem_destroy call fromnouveau_gem_object_del to nouveau_bo_del_ttm. This ensures that it willbe run after ttm_bo_delayed_delete.

CVE-2025-37786 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: dsa: free routing table on probe failureIf complete = true in dsa_tree_setup(), it means that we are the lastswitch of the tree which is successfully probing, and we should besetting up all switches from our probe path.After "complete" becomes true, dsa_tree_setup_cpu_ports() or anysubsequent function may fail. If that happens, the entire tree setup isin limbo: the first N-1 switches have successfully finished probing(doing nothing but having allocated persistent memory in the tree'sdst->ports, and maybe dst->rtable), and switch N failed to probe, endingthe tree setup process before anything is tangible from the user's PoV.If switch N fails to probe, its memory (ports) will be freed and removedfrom dst->ports. However, the dst->rtable elements pointing to its ports,as created by dsa_link_touch(), will remain there, and will lead touse-after-free if dereferenced.If dsa_tree_setup_switches() returns -EPROBE_DEFER, which is entirelypossible because that is where ds->ops->setup() is, we get a kasanreport like this:==================================================================BUG: KASAN: slab-use-after-free in mv88e6xxx_setup_upstream_port+0x240/0x568Read of size 8 at addr ffff000004f56020 by task kworker/u8:3/42Call trace: __asan_report_load8_noabort+0x20/0x30 mv88e6xxx_setup_upstream_port+0x240/0x568 mv88e6xxx_setup+0xebc/0x1eb0 dsa_register_switch+0x1af4/0x2ae0 mv88e6xxx_register_switch+0x1b8/0x2a8 mv88e6xxx_probe+0xc4c/0xf60 mdio_probe+0x78/0xb8 really_probe+0x2b8/0x5a8 __driver_probe_device+0x164/0x298 driver_probe_device+0x78/0x258 __device_attach_driver+0x274/0x350Allocated by task 42: __kasan_kmalloc+0x84/0xa0 __kmalloc_cache_noprof+0x298/0x490 dsa_switch_touch_ports+0x174/0x3d8 dsa_register_switch+0x800/0x2ae0 mv88e6xxx_register_switch+0x1b8/0x2a8 mv88e6xxx_probe+0xc4c/0xf60 mdio_probe+0x78/0xb8 really_probe+0x2b8/0x5a8 __driver_probe_device+0x164/0x298 driver_probe_device+0x78/0x258 __device_attach_driver+0x274/0x350Freed by task 42: __kasan_slab_free+0x48/0x68 kfree+0x138/0x418 dsa_register_switch+0x2694/0x2ae0 mv88e6xxx_register_switch+0x1b8/0x2a8 mv88e6xxx_probe+0xc4c/0xf60 mdio_probe+0x78/0xb8 really_probe+0x2b8/0x5a8 __driver_probe_device+0x164/0x298 driver_probe_device+0x78/0x258 __device_attach_driver+0x274/0x350The simplest way to fix the bug is to delete the routing table in itsentirety. dsa_tree_setup_routing_table() has no problem in regeneratingit even if we deleted links between ports other than those of switch N,because dsa_link_touch() first checks whether the port pair alreadyexists in dst->rtable, allocating if not.The deletion of the routing table in its entirety already exists indsa_tree_teardown(), so refactor that into a function that can also becalled from the tree setup error path.In my analysis of the commit to blame, it is the one which addeddsa_link elements to dst->rtable. Prior to that, each switch had its ownds->rtable which is freed when the switch fails to probe. But the treeis potentially persistent memory.

Description: In the Linux kernel, the following vulnerability has been resolved:net: dsa: mv88e6xxx: avoid unregistering devlink regions which were never registeredRussell King reports that a system with mv88e6xxx dereferences a NULLpointer when unbinding this driver:https://lore.kernel.org/netdev/Z_lRkMlTJ1KQ0kVX@shell.armlinux.org.uk/The crash seems to be in devlink_region_destroy(), which is not NULLtolerant but is given a NULL devlink global region pointer.At least on some chips, some devlink regions are conditionally registeredsince the blamed commit, see mv88e6xxx_setup_devlink_regions_global(): if (cond && !cond(chip)) continue;These are MV88E6XXX_REGION_STU and MV88E6XXX_REGION_PVT. If the chipdoes not have an STU or PVT, it should crash like this.To fix the issue, avoid unregistering those regions which are NULL, i.e.were skipped at mv88e6xxx_setup_devlink_regions_global() time.

Description: In the Linux kernel, the following vulnerability has been resolved:cxgb4: fix memory leak in cxgb4_init_ethtool_filters() error pathIn the for loop used to allocate the loc_array and bmap for each port, amemory leak is possible when the allocation for loc_array succeeds,but the allocation for bmap fails. This is because when the control flowgoes to the label free_eth_finfo, only the allocations starting from(i-1)th iteration are freed.Fix that by freeing the loc_array in the bmap allocation error path.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: mac80211: Purge vif txq in ieee80211_do_stop()After ieee80211_do_stop() SKB from vif's txq could still be processed.Indeed another concurrent vif schedule_and_wake_txq call could causethose packets to be dequeued (see ieee80211_handle_wake_tx_queue())without checking the sdata current state.Because vif.drv_priv is now cleared in this function, this could lead todriver crash.For example in ath12k, ahvif is store in vif.drv_priv.

Testing indicates writes to otherregisters are not sufficient to prevent the fatal trap, however the valuedoes not appear to matter.

CVE-2025-37875 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:igc: fix PTM cycle trigger logicWriting to clear the PTM status 'valid' bit while the PTM cycle istriggered results in unreliable PTM operation. To fix this, clear thePTM 'trigger' and status after each PTM transaction.The issue can be reproduced with the following:$ sudo phc2sys -R 1000 -O 0 -i tsn0 -mNote: 1000 Hz (-R 1000) is unrealistically large, but provides a way toquickly reproduce the issue.PHC2SYS exits with:"ioctl PTP_OFFSET_PRECISE: Connection timed out" when the PTM transaction failsThis patch also fixes a hang in igc_probe() when loading the igcdriver in the kdump kernel on systems supporting PTM.The igc driver running in the base kernel enables PTM trigger inigc_probe(). Therefore the driver is always in PTM trigger mode,except in brief periods when manually triggering a PTM cycle.When a crash occurs, the NIC is reset while PTM trigger is enabled.Due to a hardware problem, the NIC is subsequently in a bad busmasterstate and doesn't handle register reads/writes. When runningigc_probe() in the kdump kernel, the first register access to a NICregister hangs driver probing and ultimately breaks kdump.With this patch, igc has PTM trigger disabled most of the time,and the trigger is only enabled for very brief (10 - 100 us) periodswhen manually triggering a PTM cycle. Chances that a crash occursduring a PTM trigger are not 0, but extremely reduced.

CVE-2025-37931 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: adjust subpage bit start based on sectorsizeWhen running machines with 64k page size and a 16k nodesize we startedseeing tree log corruption in production. This turned out to be becausewe were not writing out dirty blocks sometimes, so this in fact affectsall metadata writes.When writing out a subpage EB we scan the subpage bitmap for a dirtyrange. If the range isn't dirty we do bit_start++;to move onto the next bit. The problem is the bitmap is based on thenumber of sectors that an EB has. So in this case, we have a 64kpagesize, 16k nodesize, but a 4k sectorsize. This means our bitmap is 4bits for every node. With a 64k page size we end up with 4 nodes perpage.To make this easier this is how everything looks[0 16k 32k 48k ] logical address[0 4 8 12 ] radix tree offset[ 64k page ] folio[ 16k eb ][ 16k eb ][ 16k eb ][ 16k eb ] extent buffers[ | | | | | | | | | | | | | | | | ] bitmapNow we use all of our addressing based on fs_info->sectorsize_bits, soas you can see the above our 16k eb->start turns into radix entry 4.When we find a dirty range for our eb, we correctly do bit_start +=sectors_per_node, because if we start at bit 0, the next bit for thenext eb is 4, to correspond to eb->start 16k.However if our range is clean, we will do bit_start++, which will nowput us offset from our radix tree entries.In our case, assume that the first time we check the bitmap the block isnot dirty, we increment bit_start so now it == 1, and then we looparound and check again. This time it is dirty, and we go to find thatstart using the following equation start = folio_start + bit_start * fs_info->sectorsize;so in the case above, eb->start 0 is now dirty, and we calculate startas 0 + 1 * fs_info->sectorsize = 4096 4096 >> 12 = 1Now we're looking up the radix tree for 1, and we won't find an eb.What's worse is now we're using bit_start == 1, so we do bit_start +=sectors_per_node, which is now 5. If that eb is dirty we will run intothe same thing, we will look at an offset that is not populated in theradix tree, and now we're skipping the writeout of dirty extent buffers.The best fix for this is to not use sectorsize_bits to address nodes,but that's a larger change. Since this is a fs corruption problem fixit simply by always using sectors_per_node to increment the start bit.

Description: In the Linux kernel, the following vulnerability has been resolved:tracing: Verify event formats that have "%*p.."The trace event verifier checks the formats of trace events to make surethat they do not point at memory that is not in the trace event itself orin data that will never be freed. If an event references data that wasallocated when the event triggered and that same data is freed before theevent is read, then the kernel can crash by reading freed memory.The verifier runs at boot up (or module load) and scans the print formatsof the events and checks their arguments to make sure that dereferencedpointers are safe. If the format uses "%*p.." the verifier will ignore it,and that could be dangerous. Cover this case as well.Also add to the sample code a use case of "%*pbl".

CVE-2025-37945 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: phy: allow MDIO bus PM ops to start/stop state machine for phylink-controlled PHYDSA has 2 kinds of drivers:1. Those who call dsa_switch_suspend() and dsa_switch_resume() from their device PM ops: qca8k-8xxx, bcm_sf2, microchip ksz2. Those who don't: all others. The above methods should be optional.For type 1, dsa_switch_suspend() calls dsa_user_suspend() -> phylink_stop(),and dsa_switch_resume() calls dsa_user_resume() -> phylink_start().These seem good candidates for setting mac_managed_pm = true becausethat is essentially its definition [1], but that does not seem to be thebiggest problem for now, and is not what this change focuses on.Talking strictly about the 2nd category of DSA drivers here (whichdo not have MAC managed PM, meaning that for their attached PHYs,mdio_bus_phy_suspend() and mdio_bus_phy_resume() should run in full),I have noticed that the following warning from mdio_bus_phy_resume() istriggered: WARN_ON(phydev->state != PHY_HALTED && phydev->state != PHY_READY && phydev->state != PHY_UP);because the PHY state machine is running.It's running as a result of a previous dsa_user_open() -> ... ->phylink_start() -> phy_start() having been initiated by the user.The previous mdio_bus_phy_suspend() was supposed to have calledphy_stop_machine(), but it didn't. So this is why the PHY is in statePHY_NOLINK by the time mdio_bus_phy_resume() runs.mdio_bus_phy_suspend() did not call phy_stop_machine() because forphylink, the phydev->adjust_link function pointer is NULL. This seems atechnicality introduced by commit fddd91016d16 ("phylib: fix PAL statemachine restart on resume"). That commit was written before phylinkexisted, and was intended to avoid crashing with consumer drivers whichdon't use the PHY state machine - phylink always does, when using a PHY.But phylink itself has historically not been developed withsuspend/resume in mind, and apparently not tested too much in thatscenario, allowing this bug to exist unnoticed for so long. Plus, priorto the WARN_ON(), it would have likely been invisible.This issue is not in fact restricted to type 2 DSA drivers (according tothe above ad-hoc classification), but can be extrapolated to any MACdriver with phylink and MDIO-bus-managed PHY PM ops. DSA is just wherethe issue was reported. Assuming mac_managed_pm is set correctly, aquick search indicates the following other drivers might be affected:$ grep -Zlr PHYLINK_NETDEV drivers/ | xargs -0 grep -L mac_managed_pmdrivers/net/ethernet/atheros/ag71xx.cdrivers/net/ethernet/microchip/sparx5/sparx5_main.cdrivers/net/ethernet/microchip/lan966x/lan966x_main.cdrivers/net/ethernet/freescale/dpaa2/dpaa2-mac.cdrivers/net/ethernet/freescale/fs_enet/fs_enet-main.cdrivers/net/ethernet/freescale/dpaa/dpaa_eth.cdrivers/net/ethernet/freescale/ucc_geth.cdrivers/net/ethernet/freescale/enetc/enetc_pf_common.cdrivers/net/ethernet/marvell/mvpp2/mvpp2_main.cdrivers/net/ethernet/marvell/mvneta.cdrivers/net/ethernet/marvell/prestera/prestera_main.cdrivers/net/ethernet/mediatek/mtk_eth_soc.cdrivers/net/ethernet/altera/altera_tse_main.cdrivers/net/ethernet/wangxun/txgbe/txgbe_phy.cdrivers/net/ethernet/meta/fbnic/fbnic_phylink.cdrivers/net/ethernet/tehuti/tn40_phy.cdrivers/net/ethernet/mscc/ocelot_net.cMake the existing conditions dependent on the PHY device having aphydev->phy_link_change() implementation equal to the defaultphy_link_change() provided by phylib. Otherwise, we implicitly know thatthe phydev has the phylink-provided phylink_phy_change() callback, andwhen phylink is used, the PHY state machine always needs to be stopped/started on the suspend/resume path. The code is structured as such thatif phydev->phy_link_change() is absent, it is a matter of time until thekernel will crash - no need to further complicate the test.Thus, for the situation where the PM is not managed b---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: SVM: Forcibly leave SMM mode on SHUTDOWN interceptionPreviously, commit ed129ec9057f ("KVM: x86: forcibly leave nested modeon vCPU reset") addressed an issue where a triple fault occurring innested mode could lead to use-after-free scenarios. However, the commitdid not handle the analogous situation for System Management Mode (SMM).This omission results in triggering a WARN when KVM forces a vCPU INITafter SHUTDOWN interception while the vCPU is in SMM. This situation wasreprodused using Syzkaller by: 1) Creating a KVM VM and vCPU 2) Sending a KVM_SMI ioctl to explicitly enter SMM 3) Executing invalid instructions causing consecutive exceptions and eventually a triple faultThe issue manifests as follows: WARNING: CPU: 0 PID: 25506 at arch/x86/kvm/x86.c:12112 kvm_vcpu_reset+0x1d2/0x1530 arch/x86/kvm/x86.c:12112 Modules linked in: CPU: 0 PID: 25506 Comm: syz-executor.0 Not tainted 6.1.130-syzkaller-00157-g164fe5dde9b6 #0 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014 RIP: 0010:kvm_vcpu_reset+0x1d2/0x1530 arch/x86/kvm/x86.c:12112 Call Trace: shutdown_interception+0x66/0xb0 arch/x86/kvm/svm/svm.c:2136 svm_invoke_exit_handler+0x110/0x530 arch/x86/kvm/svm/svm.c:3395 svm_handle_exit+0x424/0x920 arch/x86/kvm/svm/svm.c:3457 vcpu_enter_guest arch/x86/kvm/x86.c:10959 [inline] vcpu_run+0x2c43/0x5a90 arch/x86/kvm/x86.c:11062 kvm_arch_vcpu_ioctl_run+0x50f/0x1cf0 arch/x86/kvm/x86.c:11283 kvm_vcpu_ioctl+0x570/0xf00 arch/x86/kvm/../../../virt/kvm/kvm_main.c:4122 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:870 [inline] __se_sys_ioctl fs/ioctl.c:856 [inline] __x64_sys_ioctl+0x19a/0x210 fs/ioctl.c:856 do_syscall_x64 arch/x86/entry/common.c:51 [inline] do_syscall_64+0x35/0x80 arch/x86/entry/common.c:81 entry_SYSCALL_64_after_hwframe+0x6e/0xd8Architecturally, INIT is blocked when the CPU is in SMM, hence KVM's WARN()in kvm_vcpu_reset() to guard against KVM bugs, e.g. to detect improperemulation of INIT. SHUTDOWN on SVM is a weird edge case where KVM needs todo _something_ sane with the VMCB, since it's technically undefined, andINIT is the least awful choice given KVM's ABI.So, double down on stuffing INIT on SHUTDOWN, and force the vCPU out ofSMM to avoid any weirdness (and the WARN).Found by Linux Verification Center (linuxtesting.org) with Syzkaller.[sean: massage changelog, make it clear this isn't architectural behavior]

When we decrypt the IPsec packet,the XFRM state used for decryption is set in the skb extensions. Thisinformation is preserved across the netns switch. When we reach theXFRM policy check in the container's netns, __xfrm_policy_check dropsthe packet with LINUX_MIB_XFRMINNOPOLS because a (container-side) XFRMpolicy can't be found that matches the (host-side) XFRM state used fordecryption.This patch fixes this by scrubbing the packet when usingbpf_redirect_peer, as is done on typical netns switches via vethdevices except skb->mark and skb->tstamp are not zeroed.

Description: In the Linux kernel, the following vulnerability has been resolved:iio: light: opt3001: fix deadlock due to concurrent flag accessThe threaded IRQ function in this driver is reading the flag twice: once tolock a mutex and once to unlock it. Even though the code setting the flagis designed to prevent it, there are subtle cases where the flag could betrue at the mutex_lock stage and false at the mutex_unlock stage. Thisresults in the mutex not being unlocked, resulting in a deadlock.Fix it by making the opt3001_irq() code generally more robust, reading theflag into a variable and using the variable value at both stages.

CVE-2025-37989 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: phy: leds: fix memory leakA network restart test on a router led to an out-of-memory condition,which was traced to a memory leak in the PHY LED trigger code.The root cause is misuse of the devm API. The registration function(phy_led_triggers_register) is called from phy_attach_direct, notphy_probe, and the unregister function (phy_led_triggers_unregister)is called from phy_detach, not phy_remove. This means the register andunregister functions can be called multiple times for the same PHYdevice, but devm-allocated memory is not freed until the driver isunbound.This also prevents kmemleak from detecting the leak, as the devm APIinternally stores the allocated pointer.Fix this by replacing devm_kzalloc/devm_kcalloc with standardkzalloc/kcalloc, and add the corresponding kfree calls in the unregisterpath.

CVE-2025-38147 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:calipso: Don't call calipso functions for AF_INET sk.syzkaller reported a null-ptr-deref in txopt_get(). [0]The offset 0x70 was of struct ipv6_txoptions in struct ipv6_pinfo,so struct ipv6_pinfo was NULL there.However, this never happens for IPv6 sockets as inet_sk(sk)->pinet6is always set in inet6_create(), meaning the socket was not IPv6 one.The root cause is missing validation in netlbl_conn_setattr().netlbl_conn_setattr() switches branches based on structsockaddr.sa_family, which is passed from userspace. However,netlbl_conn_setattr() does not check if the address family matchesthe socket.The syzkaller must have called connect() for an IPv6 address onan IPv4 socket.We have a proper validation in tcp_v[46]_connect(), butsecurity_socket_connect() is called in the earlier stage.Let's copy the validation to netlbl_conn_setattr().[0]:Oops: general protection fault, probably for non-canonical address 0xdffffc000000000e: 0000 [#1] PREEMPT SMP KASAN NOPTIKASAN: null-ptr-deref in range [0x0000000000000070-0x0000000000000077]CPU: 2 UID: 0 PID: 12928 Comm: syz.9.1677 Not tainted 6.12.0 #1Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014RIP: 0010:txopt_get include/net/ipv6.h:390 [inline]RIP: 0010:Code: 02 00 00 49 8b ac 24 f8 02 00 00 e8 84 69 2a fd e8 ff 00 16 fd 48 8d 7d 70 48 b8 00 00 00 00 00 fc ff df 48 89 fa 48 c1 ea 03 <80> 3c 02 00 0f 85 53 02 00 00 48 8b 6d 70 48 85 ed 0f 84 ab 01 00RSP: 0018:ffff88811b8afc48 EFLAGS: 00010212RAX: dffffc0000000000 RBX: 1ffff11023715f8a RCX: ffffffff841ab00cRDX: 000000000000000e RSI: ffffc90007d9e000 RDI: 0000000000000070RBP: 0000000000000000 R08: ffffed1023715f9d R09: ffffed1023715f9eR10: ffffed1023715f9d R11: 0000000000000003 R12: ffff888123075f00R13: ffff88810245bd80 R14: ffff888113646780 R15: ffff888100578a80FS: 00007f9019bd7640(0000) GS:ffff8882d2d00000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007f901b927bac CR3: 0000000104788003 CR4: 0000000000770ef0PKRU: 80000000Call Trace: calipso_sock_setattr+0x56/0x80 net/netlabel/netlabel_calipso.c:557 netlbl_conn_setattr+0x10c/0x280 net/netlabel/netlabel_kapi.c:1177 selinux_netlbl_socket_connect_helper+0xd3/0x1b0 security/selinux/netlabel.c:569 selinux_netlbl_socket_connect_locked security/selinux/netlabel.c:597 [inline] selinux_netlbl_socket_connect+0xb6/0x100 security/selinux/netlabel.c:615 selinux_socket_connect+0x5f/0x80 security/selinux/hooks.c:4931 security_socket_connect+0x50/0xa0 security/security.c:4598 __sys_connect_file+0xa4/0x190 net/socket.c:2067 __sys_connect+0x12c/0x170 net/socket.c:2088 __do_sys_connect net/socket.c:2098 [inline] __se_sys_connect net/socket.c:2095 [inline] __x64_sys_connect+0x73/0xb0 net/socket.c:2095 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xaa/0x1b0 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7fRIP: 0033:0x7f901b61a12dCode: 02 b8 ff ff ff ff c3 66 0f 1f 44 00 00 f3 0f 1e fa 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 a8 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007f9019bd6fa8 EFLAGS: 00000246 ORIG_RAX: 000000000000002aRAX: ffffffffffffffda RBX: 00007f901b925fa0 RCX: 00007f901b61a12dRDX: 000000000000001c RSI: 0000200000000140 RDI: 0000000000000003RBP: 00007f901b701505 R08: 0000000000000000 R09: 0000000000000000R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000R13: 0000000000000000 R14: 00007f901b5b62a0 R15: 00007f9019bb7000 Modules linked in:

Description: In the Linux kernel, the following vulnerability has been resolved:ptp: remove ptp->n_vclocks check logic in ptp_vclock_in_use()There is no disagreement that we should check both ptp->is_virtual_clockand ptp->n_vclocks to check if the ptp virtual clock is in use.However, when we acquire ptp->n_vclocks_mux to read ptp->n_vclocks inptp_vclock_in_use(), we observe a recursive lock in the call tracestarting from n_vclocks_store().============================================WARNING: possible recursive locking detected6.15.0-rc6 #1 Not tainted--------------------------------------------syz.0.1540/13807 is trying to acquire lock:ffff888035a24868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at: ptp_vclock_in_use drivers/ptp/ptp_private.h:103 [inline]ffff888035a24868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at: ptp_clock_unregister+0x21/0x250 drivers/ptp/ptp_clock.c:415but task is already holding lock:ffff888030704868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at: n_vclocks_store+0xf1/0x6d0 drivers/ptp/ptp_sysfs.c:215other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(&ptp->n_vclocks_mux); lock(&ptp->n_vclocks_mux); *** DEADLOCK ***....============================================The best way to solve this is to remove the logic that checksptp->n_vclocks in ptp_vclock_in_use().The reason why this is appropriate is that any path that usesptp->n_vclocks must unconditionally check if ptp->n_vclocks is greaterthan 0 before unregistering vclocks, and all functions are alreadywritten this way. And in the function that uses ptp->n_vclocks, wealready get ptp->n_vclocks_mux before unregistering vclocks.Therefore, we need to remove the redundant check for ptp->n_vclocks inptp_vclock_in_use() to prevent recursive locking.

Description: In the Linux kernel, the following vulnerability has been resolved:aoe: clean device rq_list in aoedev_downdev()An aoe device's rq_list contains accepted block requests that arewaiting to be transmitted to the aoe target. This queue was added aspart of the conversion to blk_mq. However, the queue was not cleaned outwhen an aoe device is downed which caused blk_mq_freeze_queue() to sleepindefinitely waiting for those requests to complete, causing a hang. Thisfix cleans out the queue before calling blk_mq_freeze_queue().

CVE-2025-38386 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ACPICA: Refuse to evaluate a method if arguments are missingAs reported in [1], a platform firmware update that increased the numberof method parameters and forgot to update a least one of its callers,caused ACPICA to crash due to use-after-free.Since this a result of a clear AML issue that arguably cannot be fixedup by the interpreter (it cannot produce missing data out of thin air),address it by making ACPICA refuse to evaluate a method if the callerattempts to pass fewer arguments than expected to it.

Further debugging has allowed to narrow that scope down toDRM_IOCTL_I915_GEM_EXECBUFFER2, and ring_context_alloc(), specific to ringsubmission, in particular.If successful then that function, or its execlists or GuC submissionequivalent, is supposed to be called only once per GEM context engine,followed by raise of a flag that prevents the function from being calledagain. The function is expected to unwind its internal errors itself, soit may be safely called once more after it returns an error.In case of ring submission, the function first gets a reference to theengine's legacy timeline and then allocates a VMA. If the VMA allocationfails, e.g. when i915_vma_instance() called from inside is interruptedwith a signal, then ring_context_alloc() fails, leaving the timeline heldreferenced. On next I915_GEM_EXECBUFFER2 IOCTL, another reference to thetimeline is got, and only that last one is put on successful completion.As a consequence, the legacy timeline, with its underlying engine statuspage's VMA object, is still held and not released on driver unbind.Get the legacy timeline only after successful allocation of the contextengine's VMA.v2: Add a note on other submission methods (Krzysztof Karas): Both execlists and GuC submission use lrc_alloc() which seems free from a similar issue.(cherry picked from commit cc43422b3cc79eacff4c5a8ba0d224688ca9dd4f)

CVE-2025-38457 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: Abort __tc_modify_qdisc if parent class does not existLion's patch [1] revealed an ancient bug in the qdisc API.Whenever a user creates/modifies a qdisc specifying as a parent anotherqdisc, the qdisc API will, during grafting, detect that the user isnot trying to attach to a class and reject. However grafting isperformed after qdisc_create (and thus the qdiscs' init callback) isexecuted. In qdiscs that eventually call qdisc_tree_reduce_backlogduring init or change (such as fq, hhf, choke, etc), an issuearises. For example, executing the following commands:sudo tc qdisc add dev lo root handle a: htb default 2sudo tc qdisc add dev lo parent a: handle beef fqQdiscs such as fq, hhf, choke, etc unconditionally invokeqdisc_tree_reduce_backlog() in their control path init() or change() whichthen causes a failure to find the child class; however, that does not stopthe unconditional invocation of the assumed child qdisc's qlen_notify witha null class. All these qdiscs make the assumption that class is non-null.The solution is ensure that qdisc_leaf() which looks up the parentclass, and is invoked prior to qdisc_create(), should return failure onnot finding the class.In this patch, we leverage qdisc_leaf to return ERR_PTRs whenever theparentid doesn't correspond to a class, so that we can detect itearlier on and abort before qdisc_create is called.[1] https://lore.kernel.org/netdev/d912cbd7-193b-4269-9857-525bee8bbb6a@gmail.com/

Description: In the Linux kernel, the following vulnerability has been resolved:netlink: Fix wraparounds of sk->sk_rmem_alloc.Netlink has this pattern in some places if (atomic_read(&sk->sk_rmem_alloc) > sk->sk_rcvbuf) atomic_add(skb->truesize, &sk->sk_rmem_alloc);, which has the same problem fixed by commit 5a465a0da13e ("udp:Fix multiple wraparounds of sk->sk_rmem_alloc.").For example, if we set INT_MAX to SO_RCVBUFFORCE, the conditionis always false as the two operands are of int.Then, a single socket can eat as many skb as possible until OOMhappens, and we can see multiple wraparounds of sk->sk_rmem_alloc.Let's fix it by using atomic_add_return() and comparing the twovariables as unsigned int.Before: [root@fedora ~]# ss -f netlink Recv-Q Send-Q Local Address:Port Peer Address:Port -1668710080 0 rtnl:nl_wraparound/293 *After: [root@fedora ~]# ss -f netlink Recv-Q Send-Q Local Address:Port Peer Address:Port 2147483072 0 rtnl:nl_wraparound/290 * ^ `--- INT_MAX - 576

It also meansthis is the block group with the highest start offset, so there are nohigher keys in the extent root, hence btrfs_search_slot_for_read()returns 1 (no higher key found).Fix this by asserting 'ret' is 0 only if the block group tree featureis not enabled, in which case we should find a block group item forthe block group since it's stored in the extent root and block groupitem keys are greater than extent item keys (the value forBTRFS_BLOCK_GROUP_ITEM_KEY is 192 and for BTRFS_EXTENT_ITEM_KEY andBTRFS_METADATA_ITEM_KEY the values are 168 and 169 respectively).In case 'ret' is 1, we just need to add a record to the free spacetree which spans the whole block group, and we can achieve this bymaking 'ret == 0' as the while loop's condition.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: mac80211: reject VHT opmode for unsupported channel widthsVHT operating mode notifications are not defined for channel widthsbelow 20 MHz. In particular, 5 MHz and 10 MHz are not valid under theVHT specification and must be rejected.Without this check, malformed notifications using these widths mayreach ieee80211_chan_width_to_rx_bw(), leading to a WARN_ON due toinvalid input. This issue was reported by syzbot.Reject these unsupported widths early in sta_link_apply_parameters()when opmode_notif is used. The accepted set includes 20, 40, 80, 160,and 80+80 MHz, which are valid for VHT. While 320 MHz is not definedfor VHT, it is allowed to avoid rejecting HE or EHT clients that maystill send a VHT opmode notification.

CVE-2025-38516 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:pinctrl: qcom: msm: mark certain pins as invalid for interruptsOn some platforms, the UFS-reset pin has no interrupt logic in TLMM butis nevertheless registered as a GPIO in the kernel. This enables theuser-space to trigger a BUG() in the pinctrl-msm driver by running, forexample: `gpiomon -c 0 113` on RB2.The exact culprit is requesting pins whose intr_detection_width settingis not 1 or 2 for interrupts. This hits a BUG() inmsm_gpio_irq_set_type(). Potentially crashing the kernel due to aninvalid request from user-space is not optimal, so let's go through thepins and mark those that would fail the check as invalid for the irq chipas we should not even register them as available irqs.This function can be extended if we determine that there are morecorner-cases like this.

CVE-2025-38524 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: Fix recv-recv race of completed callIf a call receives an event (such as incoming data), the call gets placedon the socket's queue and a thread in recvmsg can be awakened to go andprocess it. Once the thread has picked up the call off of the queue,further events will cause it to be requeued, and once the socket lock isdropped (recvmsg uses call->user_mutex to allow the socket to be used inparallel), a second thread can come in and its recvmsg can pop the call offthe socket queue again.In such a case, the first thread will be receiving stuff from the call andthe second thread will be blocked on call->user_mutex. The first threadcan, at this point, process both the event that it picked call for and theevent that the second thread picked the call for and may see the callterminate - in which case the call will be "released", decoupling the callfrom the user call ID assigned to it (RXRPC_USER_CALL_ID in the controlmessage).The first thread will return okay, but then the second thread will wake upholding the user_mutex and, if it sees that the call has been released bythe first thread, it will BUG thusly: kernel BUG at net/rxrpc/recvmsg.c:474!Fix this by just dequeuing the call and ignoring it if it is seen to bealready released. We can't tell userspace about it anyway as the user callID has become stale.

Description: In the Linux kernel, the following vulnerability has been resolved:phy: tegra: xusb: Fix unbalanced regulator disable in UTMI PHY modeWhen transitioning from USB_ROLE_DEVICE to USB_ROLE_NONE, the codeassumed that the regulator should be disabled. However, if the regulatoris marked as always-on, regulator_is_enabled() continues to return true,leading to an incorrect attempt to disable a regulator which is notenabled.This can result in warnings such as:[ 250.155624] WARNING: CPU: 1 PID: 7326 at drivers/regulator/core.c:3004_regulator_disable+0xe4/0x1a0[ 250.155652] unbalanced disables for VIN_SYS_5V0To fix this, we move the regulator control logic intotegra186_xusb_padctl_id_override() function since it's directly relatedto the ID override state. The regulator is now only disabled when the roletransitions from USB_ROLE_HOST to USB_ROLE_NONE, by checking the VBUS_IDregister. This ensures that regulator enable/disable operations areproperly balanced and only occur when actually transitioning to/from hostmode.

This leads toa crash when dereferencing an invalid state pointer.This patch prevents the crash by explicitly removing the secpathextension from the skb if the xfrm state is not found after hardwaredecryption. This ensures downstream functions do not operate on azero-length secpath.

CVE-2025-38614 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:eventpoll: Fix semi-unbounded recursionEnsure that epoll instances can never form a graph deeper thanEP_MAX_NESTS+1 links.Currently, ep_loop_check_proc() ensures that the graph is loop-free anddoes some recursion depth checks, but those recursion depth checks don'tlimit the depth of the resulting tree for two reasons: - They don't look upwards in the tree. - If there are multiple downwards paths of different lengths, only one of the paths is actually considered for the depth check since commit 28d82dc1c4ed ("epoll: limit paths").Essentially, the current recursion depth check in ep_loop_check_proc() justserves to prevent it from recursing too deeply while checking for loops.A more thorough check is done in reverse_path_check() after the new graphedge has already been created; this checks, among other things, that nopaths going upwards from any non-epoll file with a length of more than 5edges exist. However, this check does not apply to non-epoll files.As a result, it is possible to recurse to a depth of at least roughly 500,tested on v6.15. (I am unsure if deeper recursion is possible; and this mayhave changed with commit 8c44dac8add7 ("eventpoll: Fix priority inversionproblem").)To fix it:1. In ep_loop_check_proc(), note the subtree depth of each visited node,and use subtree depths for the total depth calculation even when a subtreehas already been visited.2. Add ep_get_upwards_depth_proc() for similarly determining the maximumdepth of an upwards walk.3. In ep_loop_check(), use these values to limit the total path lengthbetween epoll nodes to EP_MAX_NESTS edges.

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: pnv_php: Clean up allocated IRQs on unplugWhen the root of a nested PCIe bridge configuration is unplugged, thepnv_php driver leaked the allocated IRQ resources for the child bridges'hotplug event notifications, resulting in a panic.Fix this by walking all child buses and deallocating all its IRQ resourcesbefore calling pci_hp_remove_devices().Also modify the lifetime of the workqueue at struct pnv_php_slot::wq sothat it is only destroyed in pnv_php_free_slot(), instead ofpnv_php_disable_irq(). This is required since pnv_php_disable_irq() willnow be called by workers triggered by hot unplug interrupts, so theworkqueue needs to stay allocated.The abridged kernel panic that occurs without this patch is as follows: WARNING: CPU: 0 PID: 687 at kernel/irq/msi.c:292 msi_device_data_release+0x6c/0x9c CPU: 0 UID: 0 PID: 687 Comm: bash Not tainted 6.14.0-rc5+ #2 Call Trace: msi_device_data_release+0x34/0x9c (unreliable) release_nodes+0x64/0x13c devres_release_all+0xc0/0x140 device_del+0x2d4/0x46c pci_destroy_dev+0x5c/0x194 pci_hp_remove_devices+0x90/0x128 pci_hp_remove_devices+0x44/0x128 pnv_php_disable_slot+0x54/0xd4 power_write_file+0xf8/0x18c pci_slot_attr_store+0x40/0x5c sysfs_kf_write+0x64/0x78 kernfs_fop_write_iter+0x1b0/0x290 vfs_write+0x3bc/0x50c ksys_write+0x84/0x140 system_call_exception+0x124/0x230 system_call_vectored_common+0x15c/0x2ec[bhelgaas: tidy comments]

CVE-2025-38670 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:arm64/entry: Mask DAIF in cpu_switch_to(), call_on_irq_stack()`cpu_switch_to()` and `call_on_irq_stack()` manipulate SP to changeto different stacks along with the Shadow Call Stack if it is enabled.Those two stack changes cannot be done atomically and both functionscan be interrupted by SErrors or Debug Exceptions which, though unlikely,is very much broken : if interrupted, we can end up with mismatched stacksand Shadow Call Stack leading to clobbered stacks.In `cpu_switch_to()`, it can happen when SP_EL0 points to the new task,but x18 stills points to the old task's SCS. When the interrupt handlertries to save the task's SCS pointer, it will save the old taskSCS pointer (x18) into the new task struct (pointed to by SP_EL0),clobbering it.In `call_on_irq_stack()`, it can happen when switching from the task stackto the IRQ stack and when switching back. In both cases, we can beinterrupted when the SCS pointer points to the IRQ SCS, but SP points tothe task stack. The nested interrupt handler pushes its return addresseson the IRQ SCS. It then detects that SP points to the task stack,calls `call_on_irq_stack()` and clobbers the task SCS pointer withthe IRQ SCS pointer, which it will also use !This leads to tasks returning to addresses on the wrong SCS,or even on the IRQ SCS, triggering kernel panics via CONFIG_VMAP_STACKor FPAC if enabled.This is possible on a default config, but unlikely.However, when enabling CONFIG_ARM64_PSEUDO_NMI, DAIF is unmasked andinstead the GIC is responsible for filtering what interrupts the CPUshould receive based on priority.Given the goal of emulating NMIs, pseudo-NMIs can be received by the CPUeven in `cpu_switch_to()` and `call_on_irq_stack()`, possibly *very*frequently depending on the system configuration and workload, leadingto unpredictable kernel panics.Completely mask DAIF in `cpu_switch_to()` and restore it when returning.Do the same in `call_on_irq_stack()`, but restore and mask aroundthe branch.Mask DAIF even if CONFIG_SHADOW_CALL_STACK is not enabled for consistencyof behaviour between all configurations.Introduce and use an assembly macro for saving and masking DAIF,as the existing one saves but only masks IF.

Description: In the Linux kernel, the following vulnerability has been resolved:i2c: qup: jump out of the loop in case of timeoutOriginal logic only sets the return value but doesn't jump out of theloop if the bus is kept active by a client. This is not expected. Amalicious or buggy i2c client can hang the kernel in this case andshould be avoided. This is observed during a long time test with aPCA953x GPIO extender.Fix it by changing the logic to not only sets the return value, but alsojumps out of the loop and return to the caller with -ETIMEDOUT.

CVE-2025-38681 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm/ptdump: take the memory hotplug lock inside ptdump_walk_pgd()Memory hot remove unmaps and tears down various kernel page table regionsas required. The ptdump code can race with concurrent modifications ofthe kernel page tables. When leaf entries are modified concurrently, thedump code may log stale or inconsistent information for a VA range, butthis is otherwise not harmful.But when intermediate levels of kernel page table are freed, the dump codewill continue to use memory that has been freed and potentiallyreallocated for another purpose. In such cases, the ptdump code maydereference bogus addresses, leading to a number of potential problems.To avoid the above mentioned race condition, platforms such as arm64,riscv and s390 take memory hotplug lock, while dumping kernel page tablevia the sysfs interface /sys/kernel/debug/kernel_page_tables.Similar race condition exists while checking for pages that might havebeen marked W+X via /sys/kernel/debug/kernel_page_tables/check_wx_pageswhich in turn calls ptdump_check_wx(). Instead of solving this racecondition again, let's just move the memory hotplug lock inside genericptdump_check_wx() which will benefit both the scenarios.Drop get_online_mems() and put_online_mems() combination from all existingplatform ptdump code paths.

CVE-2025-38687 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: fix race between polling and detachingsyzbot reports a use-after-free in comedi in the below link, which isdue to comedi gladly removing the allocated async area even though pollrequests are still active on the wait_queue_head inside of it. This cancause a use-after-free when the poll entries are later triggered orremoved, as the memory for the wait_queue_head has been freed. We needto check there are no tasks queued on any of the subdevices' wait queuesbefore allowing the device to be detached by the `COMEDI_DEVCONFIG`ioctl.Tasks will read-lock `dev->attach_lock` before adding themselves to thesubdevice wait queue, so fix the problem in the `COMEDI_DEVCONFIG` ioctlhandler by write-locking `dev->attach_lock` before checking that all ofthe subdevices are safe to be deleted. This includes testing for anysleepers on the subdevices' wait queues. It remains locked until thedevice has been detached. This requires the `comedi_device_detach()`function to be refactored slightly, moving the bulk of it into newfunction `comedi_device_detach_locked()`.Note that the refactor of `comedi_device_detach()` results in`comedi_device_cancel_all()` now being called while `dev->attach_lock`is write-locked, which wasn't the case previously, but that does notmatter.Thanks to Jens Axboe for diagnosing the problem and co-developing thispatch.

CVE-2025-38691 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:pNFS: Fix uninited ptr deref in block/scsi layoutThe error occurs on the third attempt to encode extents. When functionext_tree_prepare_commit() reallocates a larger buffer to retry encodingextents, the "layoutupdate_pages" page array is initialized only after theretry loop. But ext_tree_free_commitdata() is called on every iterationand tries to put pages in the array, thus dereferencing uninitializedpointers.An additional problem is that there is no limit on the maximum possiblebuffer_size. When there are too many extents, the client may create alayoutcommit that is larger than the maximum possible RPC size acceptedby the server.During testing, we observed two typical scenarios. First, one memory pagefor extents is enough when we work with small files, append data to theend of the file, or preallocate extents before writing. But when we filla new large file without preallocating, the number of extents can be huge,and counting the number of written extents in ext_tree_encode_commit()does not help much. Since this number increases even more betweenunlocking and locking of ext_tree, the reallocated buffer may not belarge enough again and again.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: ctnetlink: fix refcount leak on table dumpThere is a reference count leak in ctnetlink_dump_table(): if (res < 0) { nf_conntrack_get(&ct->ct_general); // HERE cb->args[1] = (unsigned long)ct; ...While its very unlikely, its possible that ct == last.If this happens, then the refcount of ct was already incremented.This 2nd increment is never undone.This prevents the conntrack object from being released, which in turnkeeps prevents cnet->count from dropping back to 0.This will then block the netns dismantle (or conntrack rmmod) asnf_conntrack_cleanup_net_list() will wait forever.This can be reproduced by running conntrack_resize.sh selftest in a loop.It takes ~20 minutes for me on a preemptible kernel on average beforeI see a runaway kworker spinning in nf_conntrack_cleanup_net_list.One fix would to change this to: if (res < 0) { if (ct != last) nf_conntrack_get(&ct->ct_general);But this reference counting isn't needed in the first place.We can just store a cookie value instead.A followup patch will do the same for ctnetlink_exp_dump_table,it looks to me as if this has the same problem and likectnetlink_dump_table, we only need a 'skip hint', not the actualobject so we can apply the same cookie strategy there as well.

CVE-2025-38735 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:gve: prevent ethtool ops after shutdownA crash can occur if an ethtool operation is invokedafter shutdown() is called.shutdown() is invoked during system shutdown to stop DMA operationswithout performing expensive deallocations. It is discouraged tounregister the netdev in this path, so the device may still be visibleto userspace and kernel helpers.In gve, shutdown() tears down most internal data structures. If anethtool operation is dispatched after shutdown(), it will dereferencefreed or NULL pointers, leading to a kernel panic. While gracefulshutdown normally quiesces userspace before invoking the rebootsyscall, forced shutdowns (as observed on GCP VMs) can still triggerthis path.Fix by calling netif_device_detach() in shutdown().This marks the device as detached so the ethtool ioctl handlerwill skip dispatching operations to the driver.

CVE-2025-39673 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ppp: fix race conditions in ppp_fill_forward_pathppp_fill_forward_path() has two race conditions:1. The ppp->channels list can change between list_empty() and list_first_entry(), as ppp_lock() is not held. If the only channel is deleted in ppp_disconnect_channel(), list_first_entry() may access an empty head or a freed entry, and trigger a panic.2. pch->chan can be NULL. When ppp_unregister_channel() is called, pch->chan is set to NULL before pch is removed from ppp->channels.Fix these by using a lockless RCU approach:- Use list_first_or_null_rcu() to safely test and access the first list entry.- Convert list modifications on ppp->channels to their RCU variants and add synchronize_net() after removal.- Check for a NULL pch->chan before dereferencing it.

CVE-2025-39677 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: Fix backlog accounting in qdisc_dequeue_internalThis issue applies for the following qdiscs: hhf, fq, fq_codel, andfq_pie, and occurs in their change handlers when adjusting to the newlimit. The problem is the following in the values passed to thesubsequent qdisc_tree_reduce_backlog call given a tbf parent: When the tbf parent runs out of tokens, skbs of these qdiscs will be placed in gso_skb. Their peek handlers are qdisc_peek_dequeued, which accounts for both qlen and backlog. However, in the case of qdisc_dequeue_internal, ONLY qlen is accounted for when pulling from gso_skb. This means that these qdiscs are missing a qdisc_qstats_backlog_dec when dropping packets to satisfy the new limit in their change handlers. One can observe this issue with the following (with tc patched to support a limit of 0): export TARGET=fq tc qdisc del dev lo root tc qdisc add dev lo root handle 1: tbf rate 8bit burst 100b latency 1ms tc qdisc replace dev lo handle 3: parent 1:1 $TARGET limit 1000 echo ''; echo 'add child'; tc -s -d qdisc show dev lo ping -I lo -f -c2 -s32 -W0.001 127.0.0.1 2>&1 >/dev/null echo ''; echo 'after ping'; tc -s -d qdisc show dev lo tc qdisc change dev lo handle 3: parent 1:1 $TARGET limit 0 echo ''; echo 'after limit drop'; tc -s -d qdisc show dev lo tc qdisc replace dev lo handle 2: parent 1:1 sfq echo ''; echo 'post graft'; tc -s -d qdisc show dev lo The second to last show command shows 0 packets but a positive number (74) of backlog bytes. The problem becomes clearer in the last show command, where qdisc_purge_queue triggers qdisc_tree_reduce_backlog with the positive backlog and causes an underflow in the tbf parent's backlog (4096 Mb instead of 0).To fix this issue, the codepath for all clients of qdisc_dequeue_internalhas been simplified: codel, pie, hhf, fq, fq_pie, and fq_codel.qdisc_dequeue_internal handles the backlog adjustments for all cases thatdo not directly use the dequeue handler.The old fq_codel_change limit adjustment loop accumulated the arguments tothe subsequent qdisc_tree_reduce_backlog call through the cstats field.However, this is confusing and error prone as fq_codel_dequeue could alsopotentially mutate this field (which qdisc_dequeue_internal calls in thenon gso_skb case), so we have unified the code here with other qdiscs.

CVE-2025-39684 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: Fix use of uninitialized memory in do_insn_ioctl() and do_insnlist_ioctl()syzbot reports a KMSAN kernel-infoleak in `do_insn_ioctl()`. A kernelbuffer is allocated to hold `insn->n` samples (each of which is an`unsigned int`). For some instruction types, `insn->n` samples arecopied back to user-space, unless an error code is being returned. Theproblem is that not all the instruction handlers that need to returndata to userspace fill in the whole `insn->n` samples, so that there isan information leak. There is a similar syzbot report for`do_insnlist_ioctl()`, although it does not have a reproducer for it atthe time of writing.One culprit is `insn_rw_emulate_bits()` which is used as the handler for`INSN_READ` or `INSN_WRITE` instructions for subdevices that do not havea specific handler for that instruction, but do have an `INSN_BITS`handler. For `INSN_READ` it only fills in at most 1 sample, so if`insn->n` is greater than 1, the remaining `insn->n - 1` samples copiedto userspace will be uninitialized kernel data.Another culprit is `vm80xx_ai_insn_read()` in the "vm80xx" driver. Itnever returns an error, even if it fails to fill the buffer.Fix it in `do_insn_ioctl()` and `do_insnlist_ioctl()` by making surethat uninitialized parts of the allocated buffer are zeroed beforehandling each instruction.Thanks to Arnaud Lecomte for their fix to `do_insn_ioctl()`. That fixreplaced the call to `kmalloc_array()` with `kcalloc()`, but it is notalways necessary to clear the whole buffer.

CVE-2025-39686 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: Make insn_rw_emulate_bits() do insn->n samplesThe `insn_rw_emulate_bits()` function is used as a default handler for`INSN_READ` instructions for subdevices that have a handler for`INSN_BITS` but not for `INSN_READ`. Similarly, it is used as a defaulthandler for `INSN_WRITE` instructions for subdevices that have a handlerfor `INSN_BITS` but not for `INSN_WRITE`. It works by emulating the`INSN_READ` or `INSN_WRITE` instruction handling with a constructed`INSN_BITS` instruction. However, `INSN_READ` and `INSN_WRITE`instructions are supposed to be able read or write multiple samples,indicated by the `insn->n` value, but `insn_rw_emulate_bits()` currentlyonly handles a single sample. For `INSN_READ`, the comedi core willcopy `insn->n` samples back to user-space. (That triggered KASANkernel-infoleak errors when `insn->n` was greater than 1, but that isbeing fixed more generally elsewhere in the comedi core.)Make `insn_rw_emulate_bits()` either handle `insn->n` samples, or returnan error, to conform to the general expectation for `INSN_READ` and`INSN_WRITE` handlers.

Description: In the Linux kernel, the following vulnerability has been resolved:ftrace: Also allocate and copy hash for reading of filter filesCurrently the reader of set_ftrace_filter and set_ftrace_notrace just addsthe pointer to the global tracer hash to its iterator. Unlike the writerthat allocates a copy of the hash, the reader keeps the pointer to thefilter hashes. This is problematic because this pointer is static acrossfunction calls that release the locks that can update the global tracerhashes. This can cause UAF and similar bugs.Allocate and copy the hash for reading the filter files like it is donefor the writers. This not only fixes UAF bugs, but also makes the code abit simpler as it doesn't have to differentiate when to free theiterator's hash between writers and readers.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amd/display: fix a Null pointer dereference vulnerability[Why]A null pointer dereference vulnerability exists in the AMD display driver's(DC module) cleanup function dc_destruct().When display control context (dc->ctx) construction fails(due to memory allocation failure), this pointer remains NULL.During subsequent error handling when dc_destruct() is called,there's no NULL check before dereferencing the perf_trace member(dc->ctx->perf_trace), causing a kernel null pointer dereference crash.[How]Check if dc->ctx is non-NULL before dereferencing.(Updated commit text and removed unnecessary error message)(cherry picked from commit 9dd8e2ba268c636c240a918e0a31e6feaee19404)

CVE-2025-39713 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:media: rainshadow-cec: fix TOCTOU race condition in rain_interrupt()In the interrupt handler rain_interrupt(), the buffer full check onrain->buf_len is performed before acquiring rain->buf_lock. Thiscreates a Time-of-Check to Time-of-Use (TOCTOU) race condition, asrain->buf_len is concurrently accessed and modified in the workhandler rain_irq_work_handler() under the same lock.Multiple interrupt invocations can race, with each reading buf_lenbefore it becomes full and then proceeding. This can lead to bothinterrupts attempting to write to the buffer, incrementing buf_lenbeyond its capacity (DATA_SIZE) and causing a buffer overflow.Fix this bug by moving the spin_lock() to before the buffer fullcheck. This ensures that the check and the subsequent buffer modificationare performed atomically, preventing the race condition. An correspondingspin_unlock() is added to the overflow path to correctly release thelock.This possible bug was found by an experimental static analysis tooldeveloped by our team.

CVE-2025-39721 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: qat - flush misc workqueue during device shutdownRepeated loading and unloading of a device specific QAT driver, forexample qat_4xxx, in a tight loop can lead to a crash due to ause-after-free scenario. This occurs when a power management (PM)interrupt triggers just before the device-specific driver (e.g.,qat_4xxx.ko) is unloaded, while the core driver (intel_qat.ko) remainsloaded.Since the driver uses a shared workqueue (`qat_misc_wq`) across alldevices and owned by intel_qat.ko, a deferred routine from thedevice-specific driver may still be pending in the queue. If thisroutine executes after the driver is unloaded, it can dereference freedmemory, resulting in a page fault and kernel crash like the following: BUG: unable to handle page fault for address: ffa000002e50a01c #PF: supervisor read access in kernel mode RIP: 0010:pm_bh_handler+0x1d2/0x250 [intel_qat] Call Trace: pm_bh_handler+0x1d2/0x250 [intel_qat] process_one_work+0x171/0x340 worker_thread+0x277/0x3a0 kthread+0xf0/0x120 ret_from_fork+0x2d/0x50To prevent this, flush the misc workqueue during device shutdown toensure that all pending work items are completed before the driver isunloaded.Note: This approach may slightly increase shutdown latency if theworkqueue contains jobs from other devices, but it ensures correctnessand stability.

CVE-2025-39749 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:rcu: Protect ->defer_qs_iw_pending from data raceOn kernels built with CONFIG_IRQ_WORK=y, when rcu_read_unlock() isinvoked within an interrupts-disabled region of code [1], it will invokercu_read_unlock_special(), which uses an irq-work handler to force thesystem to notice when the RCU read-side critical section actually ends.That end won't happen until interrupts are enabled at the soonest.In some kernels, such as those booted with rcutree.use_softirq=y, theirq-work handler is used unconditionally.The per-CPU rcu_data structure's ->defer_qs_iw_pending field isupdated by the irq-work handler and is both read and updated byrcu_read_unlock_special().

In the strictKCSAN mode of operation used by RCU, this constitutes a data race onthe ->defer_qs_iw_pending field.This commit therefore disables interrupts across the portion of thercu_preempt_deferred_qs_handler() that updates the ->defer_qs_iw_pendingfield. This suffices because this handler is not a fast path.

Description: In the Linux kernel, the following vulnerability has been resolved:fs: Prevent file descriptor table allocations exceeding INT_MAXWhen sysctl_nr_open is set to a very high value (for example, 1073741816as set by systemd), processes attempting to use file descriptors nearthe limit can trigger massive memory allocation attempts that exceedINT_MAX, resulting in a WARNING in mm/slub.c: WARNING: CPU: 0 PID: 44 at mm/slub.c:5027 __kvmalloc_node_noprof+0x21a/0x288This happens because kvmalloc_array() and kvmalloc() check if therequested size exceeds INT_MAX and emit a warning when the allocation isnot flagged with __GFP_NOWARN.Specifically, when nr_open is set to 1073741816 (0x3ffffff8) and aprocess calls dup2(oldfd, 1073741880), the kernel attempts to allocate:- File descriptor array: 1073741880 * 8 bytes = 8,589,935,040 bytes- Multiple bitmaps: ~400MB- Total allocation size: > 8GB (exceeding INT_MAX = 2,147,483,647)Reproducer:1. Set /proc/sys/fs/nr_open to 1073741816: # echo 1073741816 > /proc/sys/fs/nr_open2.

Observe WARNING in dmesg at mm/slub.c:5027systemd commit a8b627a introduced automatic bumping of fs.nr_open to themaximum possible value. The rationale was that systems with memorycontrol groups (memcg) no longer need separate file descriptor limitssince memory is properly accounted. However, this change overlookedthat:1. The kernel's allocation functions still enforce INT_MAX as a maximum size regardless of memcg accounting2. Programs and tests that legitimately test file descriptor limits can inadvertently trigger massive allocations3. The resulting allocations (>8GB) are impractical and will always failsystemd's algorithm starts with INT_MAX and keeps halving the valueuntil the kernel accepts it. On most systems, this results in nr_openbeing set to 1073741816 (0x3ffffff8), which is just under 1GB of filedescriptors.While processes rarely use file descriptors near this limit in normaloperation, certain selftests (liketools/testing/selftests/core/unshare_test.c) and programs that test filedescriptor limits can trigger this issue.Fix this by adding a check in alloc_fdtable() to ensure the requestedallocation size does not exceed INT_MAX. This causes the operation tofail with -EMFILE instead of triggering a kernel warning and avoids theimpractical >8GB memory allocation request.

In zoned mode orfor compressed writes, it locks several folios for delalloc and startswriting them out. Let's call the last locked folio folio X. Suppose thewrite range only partially covers folio X, leaving some pages dirty.Process A calls btrfs_subpage_set_writeback() when building a bio. Thisfunction call clears the TOWRITE tag of folio X, whose size = 8K andthe block size = 4K. It is following state. 0 4K 8K |/////|/////| (flag: DIRTY, tag: DIRTY) <-----> Process A will write this range.Now suppose process B concurrently calls writepages() with WB_SYNC_ALL. Itcalls tag_pages_for_writeback() to tag dirty folios withPAGECACHE_TAG_TOWRITE. Since folio X is still dirty, it gets tagged. Then,B collects tagged folios using filemap_get_folios_tag() and must wait forfolio X to be written before returning from writepages(). 0 4K 8K |/////|/////| (flag: DIRTY, tag: DIRTY|TOWRITE)However, between tagging and collecting, process A may callbtrfs_subpage_set_writeback() and clear folio X's TOWRITE tag. 0 4K 8K | |/////| (flag: DIRTY|WRITEBACK, tag: DIRTY)As a result, process B won't see folio X in its batch, and returns withoutwaiting for it. This breaks the WB_SYNC_ALL ordering requirement.Fix this by using btrfs_subpage_set_writeback_keepwrite(), which retainsthe TOWRITE tag. We now manually clear the tag only after the folio becomesclean, via the xas operation.

CVE-2025-39782 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:jbd2: prevent softlockup in jbd2_log_do_checkpoint()Both jbd2_log_do_checkpoint() and jbd2_journal_shrink_checkpoint_list()periodically release j_list_lock after processing a batch of buffers toavoid long hold times on the j_list_lock. However, since both functionscontend for j_list_lock, the combined time spent waiting and processingcan be significant.jbd2_journal_shrink_checkpoint_list() explicitly calls cond_resched() whenneed_resched() is true to avoid softlockups during prolonged operations.But jbd2_log_do_checkpoint() only exits its loop when need_resched() istrue, relying on potentially sleeping functions like __flush_batch() orwait_on_buffer() to trigger rescheduling. If those functions do not sleep,the kernel may hit a softlockup.watchdog: BUG: soft lockup - CPU#3 stuck for 156s!

Description: In the Linux kernel, the following vulnerability has been resolved:bnxt_en: Fix memory corruption when FW resources change during ifdownbnxt_set_dflt_rings() assumes that it is always called before any TC hasbeen created. So it doesn't take bp->num_tc into account and assumesthat it is always 0 or 1.In the FW resource or capability change scenario, the FW will returnflags in bnxt_hwrm_if_change() that will cause the driver toreinitialize and call bnxt_cancel_reservations(). This will lead tobnxt_init_dflt_ring_mode() calling bnxt_set_dflt_rings() and bp->num_tcmay be greater than 1. This will cause bp->tx_ring[] to be sized toosmall and cause memory corruption in bnxt_alloc_cp_rings().Fix it by properly scaling the TX rings by bp->num_tc in the codepaths mentioned above. Add 2 helper functions to determinebp->tx_nr_rings and bp->tx_nr_rings_per_tc.

At this point, due to the prior trace_iterator_reset, both`iter.seq.len` and `iter.seq.size` were set to 0. Since they are equal,the WARN_ON_ONCE condition is triggered.Move the trace_printk_seq() into the if block that checks to make sure thereturn value of trace_find_next_entry_inc() is non-NULL inftrace_dump_one(), ensuring the 'iter.seq' is properly populated beforesubsequent operations.

CVE-2025-39819 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fs/smb: Fix inconsistent refcnt updateA possible inconsistent update of refcount was identified in `smb2_compound_op`.Such inconsistent update could lead to possible resource leaks.Why it is a possible bug:1. In the comment section of the function, it clearly states that thereference to `cfile` should be dropped after calling this function.2. Every control flow path would check and drop the reference to`cfile`, except the patched one.3. Existing callers would not handle refcount update of `cfile` if-ENOMEM is returned.To fix the bug, an extra goto label "out" is added, to make sure that thecleanup logic would always be respected. As the problem is caused by theallocation failure of `vars`, the cleanup logic between label "finished"and "out" can be safely ignored. According to the definition of function`is_replayable_error`, the error code of "-ENOMEM" is not recoverable.Therefore, the replay logic also gets ignored.

CVE-2025-39835 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:xfs: do not propagate ENODATA disk errors into xattr codeENODATA (aka ENOATTR) has a very specific meaning in the xfs xattr code;namely, that the requested attribute name could not be found.However, a medium error from disk may also return ENODATA. At best,this medium error may escape to userspace as "attribute not found"when in fact it's an IO (disk) error.At worst, we may oops in xfs_attr_leaf_get() when we do: error = xfs_attr_leaf_hasname(args, &bp); if (error == -ENOATTR) { xfs_trans_brelse(args->trans, bp); return error; }because an ENODATA/ENOATTR error from disk leaves us with a null bp,and the xfs_trans_brelse will then null-deref it.As discussed on the list, we really need to modify the lower levelIO functions to trap all disk errors and ensure that we don't letunique errors like this leak up into higher xfs functions - manylike this should be remapped to EIO.However, this patch directly addresses a reported bug in the xattrcode, and should be safe to backport to stable kernels. A larger-scopepatch to handle more unique errors at lower levels can follow later.(Note, prior to 07120f1abdff we did not oops, but we did return thewrong error code to userspace.)

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: lpfc: Fix buffer free/clear order in deferred receive pathFix a use-after-free window by correcting the buffer release sequence inthe deferred receive path. The code freed the RQ buffer first and onlythen cleared the context pointer under the lock. Concurrent paths (e.g.,ABTS and the repost path) also inspect and release the same pointer underthe lock, so the old order could lead to double-free/UAF.Note that the repost path already uses the correct pattern: detach thepointer under the lock, then free it after dropping the lock. Thedeferred path should do the same.

This is becausevmemmap_populate_compound_pages() is implemented in core MM code, whichdoes not handle synchronization of the top-level page tables. Instead,the core MM has historically relied on each architecture to perform thissynchronization manually.We're not the first party to encounter a crash caused by not-sync'd toplevel page tables: earlier this year, Gwan-gyeong Mun attempted to addressthe issue [1] [2] after hitting a kernel panic when x86 code accessed thevmemmap area before the corresponding top-level entries were synced. Atthat time, the issue was believed to be triggered only when struct pagewas enlarged for debugging purposes, and the patch did not get furtherupdates.It turns out that current approach of relying on each arch to handle thepage table sync manually is fragile because 1) it's easy to forget to syncthe top level page table, and 2) it's also easy to overlook that thekernel should not access the vmemmap and direct mapping areas before thesync.# The solution: Make page table sync more code robust and harder to missTo address this, Dave Hansen suggested [3] [4] introducing{pgd,p4d}_populate_kernel() for updating kernel portion of the page tablesand allow each architecture to explicitly perform synchronization wheninstalling top-level entries. With this approach, we no longer need toworry about missing the sync step, reducing the risk of futureregressions.The new interface reuses existing ARCH_PAGE_TABLE_SYNC_MASK,PGTBL_P*D_MODIFIED and arch_sync_kernel_mappings() facility used byvmalloc and ioremap to synchronize page tables.pgd_populate_kernel() looks like this:static inline void pgd_populate_kernel(unsigned long addr, pgd_t *pgd, p4d_t *p4d){ pgd_populate(&init_mm, pgd, p4d); if (ARCH_PAGE_TABLE_SYNC_MASK & PGTBL_PGD_MODIFIED) arch_sync_kernel_mappings(addr, addr);}It is worth noting that vmalloc() and apply_to_range() carefullysynchronizes page tables by calling p*d_alloc_track() andarch_sync_kernel_mappings(), and thus they are not affected by---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:ppp: fix memory leak in pad_compress_skbIf alloc_skb() fails in pad_compress_skb(), it returns NULL withoutreleasing the old skb. The caller does: skb = pad_compress_skb(ppp, skb); if (!skb) goto drop;drop: kfree_skb(skb);When pad_compress_skb() returns NULL, the reference to the old skb islost and kfree_skb(skb) ends up doing nothing, leading to a memory leak.Align pad_compress_skb() semantics with realloc(): only free the oldskb if allocation and compression succeed. At the call site, use thenew_skb variable so the original skb is not lost when pad_compress_skb()fails.

CVE-2025-39863 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: brcmfmac: fix use-after-free when rescheduling brcmf_btcoex_info workThe brcmf_btcoex_detach() only shuts down the btcoex timer, if theflag timer_on is false. However, the brcmf_btcoex_timerfunc(), whichruns as timer handler, sets timer_on to false. This creates criticalrace conditions:1.If brcmf_btcoex_detach() is called while brcmf_btcoex_timerfunc()is executing, it may observe timer_on as false and skip the call totimer_shutdown_sync().2.The brcmf_btcoex_timerfunc() may then reschedule the brcmf_btcoex_infoworker after the cancel_work_sync() has been executed, resulting inuse-after-free bugs.The use-after-free bugs occur in two distinct scenarios, depending onthe timing of when the brcmf_btcoex_info struct is freed relative tothe execution of its worker thread.Scenario 1: Freed before the worker is scheduledThe brcmf_btcoex_info is deallocated before the worker is scheduled.A race condition can occur when schedule_work(&bt_local->work) iscalled after the target memory has been freed. The sequence of eventsis detailed below:CPU0 | CPU1brcmf_btcoex_detach | brcmf_btcoex_timerfunc | bt_local->timer_on = false; if (cfg->btcoex->timer_on) | ... | cancel_work_sync(); | ... | kfree(cfg->btcoex); // FREE | | schedule_work(&bt_local->work); // USEScenario 2: Freed after the worker is scheduledThe brcmf_btcoex_info is freed after the worker has been scheduledbut before or during its execution. In this case, statements withinthe brcmf_btcoex_handler() - such as the container_of macro andsubsequent dereferences of the brcmf_btcoex_info object will causea use-after-free access. The following timeline illustrates thisscenario:CPU0 | CPU1brcmf_btcoex_detach | brcmf_btcoex_timerfunc | bt_local->timer_on = false; if (cfg->btcoex->timer_on) | ... | cancel_work_sync(); | ... | schedule_work(); // Reschedule | kfree(cfg->btcoex); // FREE | brcmf_btcoex_handler() // Worker /* | btci = container_of(....); // USE The kfree() above could | ... also occur at any point | btci-> // USE during the worker's execution| */ |To resolve the race conditions, drop the conditional check and calltimer_shutdown_sync() directly. It can deactivate the timer reliably,regardless of its current state. Once stopped, the timer_on state isthen set to false.

Description: In the Linux kernel, the following vulnerability has been resolved:libceph: fix invalid accesses to ceph_connection_v1_infoThere is a place where generic code in messenger.c is reading andanother place where it is writing to con->v1 union member withoutchecking that the union member is active (i.e. msgr1 is in use).On 64-bit systems, con->v1.auth_retry overlaps with con->v2.out_iter,so such a read is almost guaranteed to return a bogus value instead of0 when msgr2 is in use. This ends up being fairly benign because theside effect is just the invalidation of the authorizer and successivefetching of new tickets.con->v1.connect_seq overlaps with con->v2.conn_bufs and the fact thatit's being written to can cause more serious consequences, but luckilyit's not something that happens often.

The user supplied buffer tohold the fiemap information page faults calling ocfs2_page_mkwrite() whichwill take a write lock (since v2.6.27-38-g00dc417fa3e7) of the samesemaphore. This recursive semaphore will hold filesystem locks and causesa hang of the fileystem.The ip_alloc_sem protects the inode extent list and size. Release theread semphore before calling fiemap_fill_next_extent() in ocfs2_fiemap()and ocfs2_fiemap_inline(). This does an unnecessary semaphore lock/unlockon the last extent but simplifies the error path.

Description: In the Linux kernel, the following vulnerability has been resolved:mm/slub: avoid accessing metadata when pointer is invalid in object_err()object_err() reports details of an object for further debugging, such asthe freelist pointer, redzone, etc. However, if the pointer is invalid,attempting to access object metadata can lead to a crash since it doesnot point to a valid object.One known path to the crash is when alloc_consistency_checks()determines the pointer to the allocated object is invalid because of afreelist corruption, and calls object_err() to report it. The debug codeshould report and handle the corruption gracefully and not crash in theprocess.In case the pointer is NULL or check_valid_pointer() returns false forthe pointer, only print the pointer value and skip accessing metadata.

Description: In the Linux kernel, the following vulnerability has been resolved:tcp_bpf: Call sk_msg_free() when tcp_bpf_send_verdict() fails to allocate psock->cork.syzbot reported the splat below. [0]The repro does the following: 1. Load a sk_msg prog that calls bpf_msg_cork_bytes(msg, cork_bytes) 2. Attach the prog to a SOCKMAP 3. Add a socket to the SOCKMAP 4. Activate fault injection 5. Send data less than cork_bytesAt 5., the data is carried over to the next sendmsg() as it issmaller than the cork_bytes specified by bpf_msg_cork_bytes().Then, tcp_bpf_send_verdict() tries to allocate psock->cork to holdthe data, but this fails silently due to fault injection + __GFP_NOWARN.If the allocation fails, we need to revert the sk->sk_forward_allocchange done by sk_msg_alloc().Let's call sk_msg_free() when tcp_bpf_send_verdict fails to allocatepsock->cork.The "*copied" also needs to be updated such that a proper error canbe returned to the caller, sendmsg. It fails to allocate psock->cork.Nothing has been corked so far, so this patch simply sets "*copied"to 0.[0]:WARNING: net/ipv4/af_inet.c:156 at inet_sock_destruct+0x623/0x730 net/ipv4/af_inet.c:156, CPU#1: syz-executor/5983Modules linked in:CPU: 1 UID: 0 PID: 5983 Comm: syz-executor Not tainted syzkaller #0 PREEMPT(full)Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 07/12/2025RIP: 0010:inet_sock_destruct+0x623/0x730 net/ipv4/af_inet.c:156Code: 0f 0b 90 e9 62 fe ff ff e8 7a db b5 f7 90 0f 0b 90 e9 95 fe ff ff e8 6c db b5 f7 90 0f 0b 90 e9 bb fe ff ff e8 5e db b5 f7 90 <0f> 0b 90 e9 e1 fe ff ff 89 f9 80 e1 07 80 c1 03 38 c1 0f 8c 9f fcRSP: 0018:ffffc90000a08b48 EFLAGS: 00010246RAX: ffffffff8a09d0b2 RBX: dffffc0000000000 RCX: ffff888024a23c80RDX: 0000000000000100 RSI: 0000000000000fff RDI: 0000000000000000RBP: 0000000000000fff R08: ffff88807e07c627 R09: 1ffff1100fc0f8c4R10: dffffc0000000000 R11: ffffed100fc0f8c5 R12: ffff88807e07c380R13: dffffc0000000000 R14: ffff88807e07c60c R15: 1ffff1100fc0f872FS: 00005555604c4500(0000) GS:ffff888125af1000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00005555604df5c8 CR3: 0000000032b06000 CR4: 00000000003526f0Call Trace: __sk_destruct+0x86/0x660 net/core/sock.c:2339 rcu_do_batch kernel/rcu/tree.c:2605 [inline] rcu_core+0xca8/0x1770 kernel/rcu/tree.c:2861 handle_softirqs+0x286/0x870 kernel/softirq.c:579 __do_softirq kernel/softirq.c:613 [inline] invoke_softirq kernel/softirq.c:453 [inline] __irq_exit_rcu+0xca/0x1f0 kernel/softirq.c:680 irq_exit_rcu+0x9/0x30 kernel/softirq.c:696 instr_sysvec_apic_timer_interrupt arch/x86/kernel/apic/apic.c:1052 [inline] sysvec_apic_timer_interrupt+0xa6/0xc0 arch/x86/kernel/apic/apic.c:1052

But we need to callj1939_priv_put() against an extra ref held by j1939_sk_bind() call(as a part of undoing changes made by j1939_sk_bind()) as soon asNETDEV_UNREGISTER notification fires (i.e. before j1939_sk_sock_destruct()is called via j1939_sk_release()). Otherwise, the extra ref on "structj1939_priv" held by j1939_sk_bind() call prevents "struct net_device" fromdropping the usage count to 1; making it impossible forunregister_netdevice() to continue.[mkl: remove space in front of label]

Not many x86 machines actually have a "BCM4752"/"LNV4752" acpi_device2. The stack happened to contain NULL where type_name is stored

Description: In the Linux kernel, the following vulnerability has been resolved:octeontx2-pf: Fix use-after-free bugs in otx2_sync_tstamp()The original code relies on cancel_delayed_work() in otx2_ptp_destroy(),which does not ensure that the delayed work item synctstamp_work has fullycompleted if it was already running. This leads to use-after-free scenarioswhere otx2_ptp is deallocated by otx2_ptp_destroy(), while synctstamp_workremains active and attempts to dereference otx2_ptp in otx2_sync_tstamp().Furthermore, the synctstamp_work is cyclic, the likelihood of triggeringthe bug is nonnegligible.A typical race condition is illustrated below:CPU 0 (cleanup) | CPU 1 (delayed work callback)otx2_remove() | otx2_ptp_destroy() | otx2_sync_tstamp() cancel_delayed_work() | kfree(ptp) | | ptp = container_of(...); //UAF | ptp-> //UAFThis is confirmed by a KASAN report:BUG: KASAN: slab-use-after-free in __run_timer_base.part.0+0x7d7/0x8c0Write of size 8 at addr ffff88800aa09a18 by task bash/136...Call Trace: dump_stack_lvl+0x55/0x70 print_report+0xcf/0x610 ? __run_timer_base.part.0+0x7d7/0x8c0 kasan_report+0xb8/0xf0 ? __run_timer_base.part.0+0x7d7/0x8c0 __run_timer_base.part.0+0x7d7/0x8c0 ? __pfx___run_timer_base.part.0+0x10/0x10 ? __pfx_read_tsc+0x10/0x10 ? ktime_get+0x60/0x140 ? lapic_next_event+0x11/0x20 ? clockevents_program_event+0x1d4/0x2a0 run_timer_softirq+0xd1/0x190 handle_softirqs+0x16a/0x550 irq_exit_rcu+0xaf/0xe0 sysvec_apic_timer_interrupt+0x70/0x80 ...Allocated by task 1: kasan_save_stack+0x24/0x50 kasan_save_track+0x14/0x30 __kasan_kmalloc+0x7f/0x90 otx2_ptp_init+0xb1/0x860 otx2_probe+0x4eb/0xc30 local_pci_probe+0xdc/0x190 pci_device_probe+0x2fe/0x470 really_probe+0x1ca/0x5c0 __driver_probe_device+0x248/0x310 driver_probe_device+0x44/0x120 __driver_attach+0xd2/0x310 bus_for_each_dev+0xed/0x170 bus_add_driver+0x208/0x500 driver_register+0x132/0x460 do_one_initcall+0x89/0x300 kernel_init_freeable+0x40d/0x720 kernel_init+0x1a/0x150 ret_from_fork+0x10c/0x1a0 ret_from_fork_asm+0x1a/0x30Freed by task 136: kasan_save_stack+0x24/0x50 kasan_save_track+0x14/0x30 kasan_save_free_info+0x3a/0x60 __kasan_slab_free+0x3f/0x50 kfree+0x137/0x370 otx2_ptp_destroy+0x38/0x80 otx2_remove+0x10d/0x4c0 pci_device_remove+0xa6/0x1d0 device_release_driver_internal+0xf8/0x210 pci_stop_bus_device+0x105/0x150 pci_stop_and_remove_bus_device_locked+0x15/0x30 remove_store+0xcc/0xe0 kernfs_fop_write_iter+0x2c3/0x440 vfs_write+0x871/0xd70 ksys_write+0xee/0x1c0 do_syscall_64+0xac/0x280 entry_SYSCALL_64_after_hwframe+0x77/0x7f...Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensurethat the delayed work item is properly canceled before the otx2_ptp isdeallocated.This bug was initially identified through static analysis.

Description: In the Linux kernel, the following vulnerability has been resolved:x86/mce: use is_copy_from_user() to determine copy-from-user contextPatch series "mm/hwpoison: Fix regressions in memory failure handling",v4.## 1. What am I trying to do:This patchset resolves two critical regressions related to memory failurehandling that have appeared in the upstream kernel since version 5.17, ascompared to 5.10 LTS. - copyin case: poison found in user page while kernel copying from user space - instr case: poison found while instruction fetching in user space## 2. What is the expected outcome and why- For copyin case:Kernel can recover from poison found where kernel is doing get_user() orcopy_from_user() if those places get an error return and the kernel return-EFAULT to the process instead of crashing. More specifily, MCE handlerchecks the fixup handler type to decide whether an in kernel #MC can berecovered. When EX_TYPE_UACCESS is found, the PC jumps to recovery codespecified in _ASM_EXTABLE_FAULT() and return a -EFAULT to user space.- For instr case:If a poison found while instruction fetching in user space, full recoveryis possible. User process takes #PF, Linux allocates a new page and fillsby reading from storage.## 3. What actually happens and why- For copyin case: kernel panic since v5.17Commit 4c132d1d844a ("x86/futex: Remove .fixup usage") introduced a newextable fixup type, EX_TYPE_EFAULT_REG, and later patches updated theextable fixup type for copy-from-user operations, changing it fromEX_TYPE_UACCESS to EX_TYPE_EFAULT_REG. It breaks previous EX_TYPE_UACCESShandling when posion found in get_user() or copy_from_user().- For instr case: user process is killed by a SIGBUS signal due to #CMCI and #MCE raceWhen an uncorrected memory error is consumed there is a race between theCMCI from the memory controller reporting an uncorrected error with a UCNAsignature, and the core reporting and SRAR signature machine check whenthe data is about to be consumed.### Background: why *UN*corrected errors tied to *C*MCI in Intel platform [1]Prior to Icelake memory controllers reported patrol scrub events thatdetected a previously unseen uncorrected error in memory by signaling abroadcast machine check with an SRAO (Software Recoverable ActionOptional) signature in the machine check bank. This was overkill becauseit's not an urgent problem that no core is on the verge of consuming thatbad data. It's also found that multi SRAO UCE may cause nested MCEinterrupts and finally become an IERR.Hence, Intel downgrades the machine check bank signature of patrol scrubfrom SRAO to UCNA (Uncorrected, No Action required), and signal changed to#CMCI. Just to add to the confusion, Linux does take an action (inuc_decode_notifier()) to try to offline the page despite the UC*NA*signature name.### Background: why #CMCI and #MCE race when poison is consuming in Intel platform [1]Having decided that CMCI/UCNA is the best action for patrol scrub errors,the memory controller uses it for reads too. But the memory controller isexecuting asynchronously from the core, and can't tell the differencebetween a "real" read and a speculative read. So it will do CMCI/UCNA ifan error is found in any read.Thus:1) Core is clever and thinks address A is needed soon, issues a speculative read.2) Core finds it is going to use address A soon after sending the read request3) The CMCI from the memory controller is in a race with MCE from the core that will soon try to retire the load from address A.Quite often (because speculation has got better) the CMCI from the memorycontroller is delivered before the core is committed to the instructionreading address A, so the interrupt is taken, and Linux offlines the page(marking it as poison).## Why user process is killed for instr caseCommit 046545a661af ("mm/hwpoison: fix error page recovered but reported"not---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:net: dlink: handle copy_thresh allocation failureThe driver did not handle failure of `netdev_alloc_skb_ip_align()`.If the allocation failed, dereferencing `skb->protocol` could lead toa NULL pointer dereference.This patch tries to allocate `skb`. If the allocation fails, it fallsback to the normal path.Tested-on: D-Link DGE-550T Rev-A3

CVE-2025-40060 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:coresight: trbe: Return NULL pointer for allocation failuresWhen the TRBE driver fails to allocate a buffer, it currently returnsthe error code "-ENOMEM". However, the caller etm_setup_aux() onlychecks for a NULL pointer, so it misses the error. As a result, thedriver continues and eventually causes a kernel panic.Fix this by returning a NULL pointer from arm_trbe_alloc_buffer() onallocation failures. This allows that the callers can properly handlethe failure.

Description: In the Linux kernel, the following vulnerability has been resolved:tty: n_gsm: Don't block input queue by waiting MSCCurrently gsm_queue() processes incoming frames and when openinga DLC channel it calls gsm_dlci_open() which calls gsm_modem_update().If basic mode is used it calls gsm_modem_upd_via_msc() and itcannot block the input queue by waiting the response to comeinto the same input queue.Instead allow sending Modem Status Command without waiting for remoteend to respond. Define a new function gsm_modem_send_initial_msc()for this purpose. As MSC is only valid for basic encoding, it doesnot do anything for advanced or when convergence layer type 2 is used.

CVE-2025-40078 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Explicitly check accesses to bpf_sock_addrSyzkaller found a kernel warning on the following sock_addr program: 0: r0 = 0 1: r2 = *(u32 *)(r1 +60) 2: exitwhich triggers: verifier bug: error during ctx access conversion (0)This is happening because offset 60 in bpf_sock_addr corresponds to animplicit padding of 4 bytes, right after msg_src_ip4. Access to thispadding isn't rejected in sock_addr_is_valid_access and it thus laterfails to convert the access.This patch fixes it by explicitly checking the various fields ofbpf_sock_addr in sock_addr_is_valid_access.I checked the other ctx structures and is_valid_access functions anddidn't find any other similar cases. Other cases of (properly handled)padding are covered in new tests in a subsequent patch.

CVE-2025-40100 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: do not assert we found block group item when creating free space treeCurrently, when building a free space tree at populate_free_space_tree(),if we are not using the block group tree feature, we always expect to findblock group items (either extent items or a block group item with key typeBTRFS_BLOCK_GROUP_ITEM_KEY) when we search the extent tree withbtrfs_search_slot_for_read(), so we assert that we found an item. Howeverthis expectation is wrong since we can have a new block group created inthe current transaction which is still empty and for which we still havenot added the block group's item to the extent tree, in which case we donot have any items in the extent tree associated to the block group.The insertion of a new block group's block group item in the extent treehappens at btrfs_create_pending_block_groups() when it calls the helperinsert_block_group_item(). This typically is done when a transactionhandle is released, committed or when running delayed refs (either aspart of a transaction commit or when serving tickets for space reservationif we are low on free space).So remove the assertion at populate_free_space_tree() even when the blockgroup tree feature is not enabled and update the comment to mention thiscase.Syzbot reported this with the following stack trace: BTRFS info (device loop3 state M): rebuilding free space tree assertion failed: ret == 0 :: 0, in fs/btrfs/free-space-tree.c:1115 ------------[ cut here ]------------ kernel BUG at fs/btrfs/free-space-tree.c:1115!

CVE-2025-40123 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Enforce expected_attach_type for tailcall compatibilityYinhao et al. recently reported: Our fuzzer tool discovered an uninitialized pointer issue in the bpf_prog_test_run_xdp() function within the Linux kernel's BPF subsystem. This leads to a NULL pointer dereference when a BPF program attempts to deference the txq member of struct xdp_buff object.The test initializes two programs of BPF_PROG_TYPE_XDP: progA acts as theentry point for bpf_prog_test_run_xdp() and its expected_attach_type canneither be of be BPF_XDP_DEVMAP nor BPF_XDP_CPUMAP. progA calls into a slotof a tailcall map it owns. progB's expected_attach_type must be BPF_XDP_DEVMAPto pass xdp_is_valid_access() validation. The program returns struct xdp_md'segress_ifindex, and the latter is only allowed to be accessed under mentionedexpected_attach_type. progB is then inserted into the tailcall which progAcalls.The underlying issue goes beyond XDP though. Another example are programsof type BPF_PROG_TYPE_CGROUP_SOCK_ADDR. sock_addr_is_valid_access() as wellas sock_addr_func_proto() have different logic depending on the programs'expected_attach_type. Similarly, a program attached to BPF_CGROUP_INET4_GETPEERNAMEshould not be allowed doing a tailcall into a program which calls bpf_bind()out of BPF which is only enabled for BPF_CGROUP_INET4_CONNECT.In short, specifying expected_attach_type allows to open up additionalfunctionality or restrictions beyond what the basic bpf_prog_type enables.The use of tailcalls must not violate these constraints. Fix it by enforcingexpected_attach_type in __bpf_prog_map_compatible().Note that we only enforce this for tailcall maps, but not for BPF devmaps orcpumaps: There, the programs are invoked through dev_map_bpf_prog_run*() andcpu_map_bpf_prog_run*() which set up a new environment / context and thereforethese situations are not prone to this issue.

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: detect invalid INLINE_DATA + EXTENTS flag combinationsyzbot reported a BUG_ON in ext4_es_cache_extent() when opening a verityfile on a corrupted ext4 filesystem mounted without a journal.The issue is that the filesystem has an inode with both the INLINE_DATAand EXTENTS flags set: EXT4-fs error (device loop0): ext4_cache_extents:545: inode #15: comm syz.0.17: corrupted extent tree: lblk 0 < prev 66Investigation revealed that the inode has both flags set: DEBUG: inode 15 - flag=1, i_inline_off=164, has_inline=1, extents_flag=1This is an invalid combination since an inode should have either:- INLINE_DATA: data stored directly in the inode- EXTENTS: data stored in extent-mapped blocksHaving both flags causes ext4_has_inline_data() to return true, skippingextent tree validation in __ext4_iget(). The unvalidated out-of-orderextents then trigger a BUG_ON in ext4_es_cache_extent() due to integerunderflow when calculating hole sizes.Fix this by detecting this invalid flag combination early in ext4_iget()and rejecting the corrupted inode.

CVE-2025-40223 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:most: usb: Fix use-after-free in hdm_disconnecthdm_disconnect() calls most_deregister_interface(), which eventuallyunregisters the MOST interface device with device_unregister(iface->dev).If that drops the last reference, the device core may call release_mdev()immediately while hdm_disconnect() is still executing.The old code also freed several mdev-owned allocations inhdm_disconnect() and then performed additional put_device() calls.Depending on refcount order, this could lead to use-after-free ordouble-free when release_mdev() ran (or when unregister paths alsoperformed puts).Fix by moving the frees of mdev-owned allocations into release_mdev(),so they happen exactly once when the device is truly released, and bydropping the extra put_device() calls in hdm_disconnect() that areredundant after device_unregister() and most_deregister_interface().This addresses the KASAN slab-use-after-free reported by syzbot inhdm_disconnect().

CVE-2025-40233 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ocfs2: clear extent cache after moving/defragmenting extentsThe extent map cache can become stale when extents are moved ordefragmented, causing subsequent operations to see outdated extent flags. This triggers a BUG_ON in ocfs2_refcount_cal_cow_clusters().The problem occurs when:1. copy_file_range() creates a reflinked extent with OCFS2_EXT_REFCOUNTED2. ioctl(FITRIM) triggers ocfs2_move_extents()3. __ocfs2_move_extents_range() reads and caches the extent (flags=0x2)4. ocfs2_move_extent()/ocfs2_defrag_extent() calls __ocfs2_move_extent() which clears OCFS2_EXT_REFCOUNTED flag on disk (flags=0x0)5. The extent map cache is not invalidated after the move6. Later write() operations read stale cached flags (0x2) but disk has updated flags (0x0), causing a mismatch7. BUG_ON(!(rec->e_flags & OCFS2_EXT_REFCOUNTED)) triggersFix by clearing the extent map cache after each extent move/defragoperation in __ocfs2_move_extents_range(). This ensures subsequentoperations read fresh extent data from disk.

CVE-2025-40248 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:vsock: Ignore signal/timeout on connect() if already establishedDuring connect(), acting on a signal/timeout by disconnecting an alreadyestablished socket leads to several issues:1. connect() invoking vsock_transport_cancel_pkt() -> virtio_transport_purge_skbs() may race with sendmsg() invoking virtio_transport_get_credit(). This results in a permanently elevated `vvs->bytes_unsent`. Which, in turn, confuses the SOCK_LINGER handling.2. connect() resetting a connected socket's state may race with socket being placed in a sockmap. A disconnected socket remaining in a sockmap breaks sockmap's assumptions. And gives rise to WARNs.3. connect() transitioning SS_CONNECTED -> SS_UNCONNECTED allows for a transport change/drop after TCP_ESTABLISHED. Which poses a problem for any simultaneous sendmsg() or connect() and may result in a use-after-free/null-ptr-deref.Do not disconnect socket on signal/timeout. Keep the logic for unconnectedsockets: they don't linger, can't be placed in a sockmap, are rejected bysendmsg().[1]: https://lore.kernel.org/netdev/e07fd95c-9a38-4eea-9638-133e38c2ec9b@rbox.co/[2]: https://lore.kernel.org/netdev/20250317-vsock-trans-signal-race-v4-0-fc8837f3f1d4@rbox.co/[3]: https://lore.kernel.org/netdev/60f1b7db-3099-4f6a-875e-af9f6ef194f6@rbox.co/

Description: In the Linux kernel, the following vulnerability has been resolved:devlink: rate: Unset parent pointer in devl_rate_nodes_destroyThe function devl_rate_nodes_destroy is documented to "Unset parent forall rate objects". However, it was only calling the driver-specific`rate_leaf_parent_set` or `rate_node_parent_set` ops and decrementingthe parent's refcount, without actually setting the`devlink_rate->parent` pointer to NULL.This leaves a dangling pointer in the `devlink_rate` struct, which causerefcount error in netdevsim[1] and mlx5[2]. In addition, this isinconsistent with the behavior of `devlink_nl_rate_parent_node_set`,where the parent pointer is correctly cleared.This patch fixes the issue by explicitly setting `devlink_rate->parent`to NULL after notifying the driver, thus fulfilling the function'sdocumented behavior for all rate objects.[1]repro steps:echo 1 > /sys/bus/netdevsim/new_devicedevlink dev eswitch set netdevsim/netdevsim1 mode switchdevecho 1 > /sys/bus/netdevsim/devices/netdevsim1/sriov_numvfsdevlink port function rate add netdevsim/netdevsim1/test_nodedevlink port function rate set netdevsim/netdevsim1/128 parent test_nodeecho 1 > /sys/bus/netdevsim/del_devicedmesg:refcount_t: decrement hit 0; leaking memory.WARNING: CPU: 8 PID: 1530 at lib/refcount.c:31 refcount_warn_saturate+0x42/0xe0CPU: 8 UID: 0 PID: 1530 Comm: bash Not tainted 6.18.0-rc4+ #1 NONEHardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.16.0-0-gd239552ce722-prebuilt.qemu.org 04/01/2014RIP: 0010:refcount_warn_saturate+0x42/0xe0Call Trace: devl_rate_leaf_destroy+0x8d/0x90 __nsim_dev_port_del+0x6c/0x70 [netdevsim] nsim_dev_reload_destroy+0x11c/0x140 [netdevsim] nsim_drv_remove+0x2b/0xb0 [netdevsim] device_release_driver_internal+0x194/0x1f0 bus_remove_device+0xc6/0x130 device_del+0x159/0x3c0 device_unregister+0x1a/0x60 del_device_store+0x111/0x170 [netdevsim] kernfs_fop_write_iter+0x12e/0x1e0 vfs_write+0x215/0x3d0 ksys_write+0x5f/0xd0 do_syscall_64+0x55/0x10f0 entry_SYSCALL_64_after_hwframe+0x4b/0x53[2]devlink dev eswitch set pci/0000:08:00.0 mode switchdevdevlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 1000devlink port function rate add pci/0000:08:00.0/group1devlink port function rate set pci/0000:08:00.0/32768 parent group1modprobe -r mlx5_ib mlx5_fwctl mlx5_coredmesg:refcount_t: decrement hit 0; leaking memory.WARNING: CPU: 7 PID: 16151 at lib/refcount.c:31 refcount_warn_saturate+0x42/0xe0CPU: 7 UID: 0 PID: 16151 Comm: bash Not tainted 6.17.0-rc7_for_upstream_min_debug_2025_10_02_12_44 #1 NONEHardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014RIP: 0010:refcount_warn_saturate+0x42/0xe0Call Trace: devl_rate_leaf_destroy+0x8d/0x90 mlx5_esw_offloads_devlink_port_unregister+0x33/0x60 [mlx5_core] mlx5_esw_offloads_unload_rep+0x3f/0x50 [mlx5_core] mlx5_eswitch_unload_sf_vport+0x40/0x90 [mlx5_core] mlx5_sf_esw_event+0xc4/0x120 [mlx5_core] notifier_call_chain+0x33/0xa0 blocking_notifier_call_chain+0x3b/0x50 mlx5_eswitch_disable_locked+0x50/0x110 [mlx5_core] mlx5_eswitch_disable+0x63/0x90 [mlx5_core] mlx5_unload+0x1d/0x170 [mlx5_core] mlx5_uninit_one+0xa2/0x130 [mlx5_core] remove_one+0x78/0xd0 [mlx5_core] pci_device_remove+0x39/0xa0 device_release_driver_internal+0x194/0x1f0 unbind_store+0x99/0xa0 kernfs_fop_write_iter+0x12e/0x1e0 vfs_write+0x215/0x3d0 ksys_write+0x5f/0xd0 do_syscall_64+0x53/0x1f0 entry_SYSCALL_64_after_hwframe+0x4b/0x53

CVE-2025-40254 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: openvswitch: remove never-working support for setting nsh fieldsThe validation of the set(nsh(...)) action is completely wrong.It runs through the nsh_key_put_from_nlattr() function that is thesame function that validates NSH keys for the flow match and thepush_nsh() action. However, the set(nsh(...)) has a very differentmemory layout. Nested attributes in there are doubled in size incase of the masked set(). That makes proper validation impossible.There is also confusion in the code between the 'masked' flag, thatsays that the nested attributes are doubled in size containing boththe value and the mask, and the 'is_mask' that says that the valuewe're parsing is the mask. This is causing kernel crash on trying towrite into mask part of the match with SW_FLOW_KEY_PUT() duringvalidation, while validate_nsh() doesn't allocate any memory for it: BUG: kernel NULL pointer dereference, address: 0000000000000018 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 1c2383067 P4D 1c2383067 PUD 20b703067 PMD 0 Oops: Oops: 0000 [#1] SMP NOPTI CPU: 8 UID: 0 Kdump: loaded Not tainted 6.17.0-rc4+ #107 PREEMPT(voluntary) RIP: 0010:nsh_key_put_from_nlattr+0x19d/0x610 [openvswitch] Call Trace: validate_nsh+0x60/0x90 [openvswitch] validate_set.constprop.0+0x270/0x3c0 [openvswitch] __ovs_nla_copy_actions+0x477/0x860 [openvswitch] ovs_nla_copy_actions+0x8d/0x100 [openvswitch] ovs_packet_cmd_execute+0x1cc/0x310 [openvswitch] genl_family_rcv_msg_doit+0xdb/0x130 genl_family_rcv_msg+0x14b/0x220 genl_rcv_msg+0x47/0xa0 netlink_rcv_skb+0x53/0x100 genl_rcv+0x24/0x40 netlink_unicast+0x280/0x3b0 netlink_sendmsg+0x1f7/0x430 ____sys_sendmsg+0x36b/0x3a0 ___sys_sendmsg+0x87/0xd0 __sys_sendmsg+0x6d/0xd0 do_syscall_64+0x7b/0x2c0 entry_SYSCALL_64_after_hwframe+0x76/0x7eThe third issue with this process is that while trying to convertthe non-masked set into masked one, validate_set() copies and doublesthe size of the OVS_KEY_ATTR_NSH as if it didn't have any nestedattributes. It should be copying each nested attribute and doublingthem in size independently. And the process must be properly reversedduring the conversion back from masked to a non-masked variant duringthe flow dump.In the end, the only two outcomes of trying to use this action areeither validation failure or a kernel crash. And if somehow someonemanages to install a flow with such an action, it will most definitelynot do what it is supposed to, since all the keys and the masks aremixed up.Fixing all the issues is a complex task as it requires re-writingmost of the validation code.Given that and the fact that this functionality never worked sinceintroduction, let's just remove it altogether. It's better tore-introduce it later with a proper implementation instead of tryingto fix it in stable releases.

CVE-2025-40256 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:xfrm: also call xfrm_state_delete_tunnel at destroy time for states that were never addedIn commit b441cf3f8c4b ("xfrm: delete x->tunnel as we delete x"), Imissed the case where state creation fails between fullinitialization (->init_state has been called) and being inserted onthe lists.In this situation, ->init_state has been called, so for IPcomptunnels, the fallback tunnel has been created and added onto thelists, but the user state never gets added, because we fail beforethat. The user state doesn't go through __xfrm_state_delete, so wedon't call xfrm_state_delete_tunnel for those states, and we end upleaking the FB tunnel.There are several codepaths affected by this: the add/update paths, inboth net/key and xfrm, and the migrate code (xfrm_migrate,xfrm_state_migrate). A "proper" rollback of the init_state work wouldprobably be doable in the add/update code, but for migrate it getsmore complicated as multiple states may be involved.At some point, the new (not-inserted) state will be destroyed, so callxfrm_state_delete_tunnel during xfrm_state_gc_destroy. Most stateswill have their fallback tunnel cleaned up during __xfrm_state_delete,which solves the issue that b441cf3f8c4b (and other patches before it)aimed at. All states (including FB tunnels) will be removed from thelists once xfrm_state_fini has called flush_work(&xfrm_state_gc_work).

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-audio: Fix potential overflow of PCM transfer bufferThe PCM stream data in USB-audio driver is transferred over USB URBpacket buffers, and each packet size is determined dynamically. Thepacket sizes are limited by some factors such as wMaxPacketSize USBdescriptor. OTOH, in the current code, the actually used packet sizesare determined only by the rate and the PPS, which may be bigger thanthe size limit above. This results in a buffer overflow, as reportedby syzbot.Basically when the limit is smaller than the calculated packet size,it implies that something is wrong, most likely a weird USBdescriptor. So the best option would be just to return an error atthe parameter setup time before doing any further operations.This patch introduces such a sanity check, and returns -EINVAL whenthe packet size is greater than maxpacksize. The comparison withep->packsize[1] alone should suffice since it's always equal orgreater than ep->packsize[0].

Description: In the Linux kernel, the following vulnerability has been resolved:mm/secretmem: fix use-after-free race in fault handlerWhen a page fault occurs in a secret memory file created with`memfd_secret(2)`, the kernel will allocate a new folio for it, mark theunderlying page as not-present in the direct map, and add it to the filemapping.If two tasks cause a fault in the same page concurrently, both could endup allocating a folio and removing the page from the direct map, but onlyone would succeed in adding the folio to the file mapping. The task thatfailed undoes the effects of its attempt by (a) freeing the folio againand (b) putting the page back into the direct map. However, by doingthese two operations in this order, the page becomes available to theallocator again before it is placed back in the direct mapping.If another task attempts to allocate the page between (a) and (b), and thekernel tries to access it via the direct map, it would result in asupervisor not-present page fault.Fix the ordering to restore the direct map before the folio is freed.

CVE-2025-40275 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-audio: Fix NULL pointer dereference in snd_usb_mixer_controls_baddIn snd_usb_create_streams(), for UAC version 3 devices, the InterfaceAssociation Descriptor (IAD) is retrieved via usb_ifnum_to_if(). If thiscall fails, a fallback routine attempts to obtain the IAD from the nextinterface and sets a BADD profile. However, snd_usb_mixer_controls_badd()assumes that the IAD retrieved from usb_ifnum_to_if() is always valid,without performing a NULL check. This can lead to a NULL pointerdereference when usb_ifnum_to_if() fails to find the interface descriptor.This patch adds a NULL pointer check after calling usb_ifnum_to_if() insnd_usb_mixer_controls_badd() to prevent the dereference.This issue was discovered by syzkaller, which triggered the bug by sendinga crafted USB device descriptor.

Description: In the Linux kernel, the following vulnerability has been resolved:net: sched: act_ife: initialize struct tc_ife to fix KMSAN kernel-infoleakFix a KMSAN kernel-infoleak detected by the syzbot .[net?] KMSAN: kernel-infoleak in __skb_datagram_iterIn tcf_ife_dump(), the variable 'opt' was partially initialized using adesignatied initializer. While the padding bytes are reamineduninitialized. nla_put() copies the entire structure into anetlink message, these uninitialized bytes leaked to userspace.Initialize the structure with memset before assigning its fieldsto ensure all members and padding are cleared prior to beign copied.This change silences the KMSAN report and prevents potential informationleaks from the kernel memory.This fix has been tested and validated by syzbot. This patch closes thebug reported at the following syzkaller link and ensures no infoleak.

Description: In the Linux kernel, the following vulnerability has been resolved:exfat: fix improper check of dentry.stream.valid_sizeWe found an infinite loop bug in the exFAT file system that can lead to aDenial-of-Service (DoS) condition. When a dentry in an exFAT filesystem ismalformed, the following system calls - SYS_openat, SYS_ftruncate, andSYS_pwrite64 - can cause the kernel to hang.Root cause analysis shows that the size validation code in exfat_find()does not check whether dentry.stream.valid_size is negative. As a result,the system calls mentioned above can succeed and eventually trigger the DoSissue.This patch adds a check for negative dentry.stream.valid_size to preventthis vulnerability.

CVE-2025-40288 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amdgpu: Fix NULL pointer dereference in VRAM logic for APU devicesPreviously, APU platforms (and other scenarios with uninitialized VRAM managers)triggered a NULL pointer dereference in `ttm_resource_manager_usage()`. The rootcause is not that the `struct ttm_resource_manager *man` pointer itself is NULL,but that `man->bdev` (the backing device pointer within the manager) remainsuninitialized (NULL) on APUs-since APUs lack dedicated VRAM and do not fullyset up VRAM manager structures. When `ttm_resource_manager_usage()` attempts toacquire `man->bdev->lru_lock`, it dereferences the NULL `man->bdev`, leading toa kernel OOPS.1. **amdgpu_cs.c**: Extend the existing bandwidth control check in `amdgpu_cs_get_threshold_for_moves()` to include a check for `ttm_resource_manager_used()`. If the manager is not used (uninitialized `bdev`), return 0 for migration thresholds immediately-skipping VRAM-specific logic that would trigger the NULL dereference.2. **amdgpu_kms.c**: Update the `AMDGPU_INFO_VRAM_USAGE` ioctl and memory info reporting to use a conditional: if the manager is used, return the real VRAM usage; otherwise, return 0. This avoids accessing `man->bdev` when it is NULL.3. **amdgpu_virt.c**: Modify the vf2pf (virtual function to physical function) data write path. Use `ttm_resource_manager_used()` to check validity: if the manager is usable, calculate `fb_usage` from VRAM usage; otherwise, set `fb_usage` to 0 (APUs have no discrete framebuffer to report).This approach is more robust than APU-specific checks because it:- Works for all scenarios where the VRAM manager is uninitialized (not just APUs),- Aligns with TTM's design by using its native helper function,- Preserves correct behavior for discrete GPUs (which have fully initialized `man->bdev` and pass the `ttm_resource_manager_used()` check).v4: use ttm_resource_manager_used(&adev->mman.vram_mgr.manager) instead of checking the adev->gmc.is_app_apu flag (Christian)

Description: In the Linux kernel, the following vulnerability has been resolved:exfat: validate cluster allocation bits of the allocation bitmapsyzbot created an exfat image with cluster bits not set for the allocationbitmap. exfat-fs reads and uses the allocation bitmap without checkingthis. The problem is that if the start cluster of the allocation bitmapis 6, cluster 6 can be allocated when creating a directory with mkdir.exfat zeros out this cluster in exfat_mkdir, which can delete existingentries. This can reallocate the allocated entries. In addition,the allocation bitmap is also zeroed out, so cluster 6 can be reallocated.This patch adds exfat_test_bitmap_range to validate that clusters used forthe allocation bitmap are correctly marked as in-use.

And if hostapd receives an ANQP Query REQAction frame even from an un-associated STA, the brcmfmac driver triesto use an uninitialized P2P vif pointer for sending the IOVAR to firmware.This NULL pointer dereferencing triggers a driver crash.

Description: In the Linux kernel, the following vulnerability has been resolved:net: stmmac: Correctly handle Rx checksum offload errorsThe stmmac_rx function would previously set skb->ip_summed toCHECKSUM_UNNECESSARY if hardware checksum offload (CoE) was enabledand the packet was of a known IP ethertype.However, this logic failed to check if the hardware had actuallyreported a checksum error. The hardware status, indicating a header orpayload checksum failure, was being ignored at this stage. This couldcause corrupt packets to be passed up the network stack as valid.This patch corrects the logic by checking the `csum_none` status flag,which is set when the hardware reports a checksum error. If this flagis set, skb->ip_summed is now correctly set to CHECKSUM_NONE,ensuring the kernel's network stack will perform its own validation andproperly handle the corrupt packet.

Description: In the Linux kernel, the following vulnerability has been resolved:futex: Don't leak robust_list pointer on exec racesys_get_robust_list() and compat_get_robust_list() use ptrace_may_access()to check if the calling task is allowed to access another task'srobust_list pointer. This check is racy against a concurrent exec() in thetarget process.During exec(), a task may transition from a non-privileged binary to aprivileged one (e.g., setuid binary) and its credentials/memory mappingsmay change. If get_robust_list() performs ptrace_may_access() beforethis transition, it may erroneously allow access to sensitive informationafter the target becomes privileged.A racy access allows an attacker to exploit a window during whichptrace_may_access() passes before a target process transitions to aprivileged state via exec().For example, consider a non-privileged task T that is about to execute asetuid-root binary. An attacker task A calls get_robust_list(T) while Tis still unprivileged. Since ptrace_may_access() checks permissionsbased on current credentials, it succeeds. However, if T begins execimmediately afterwards, it becomes privileged and may change its memorymappings. Because get_robust_list() proceeds to access T->robust_listwithout synchronizing with exec() it may read user-space pointers from anow-privileged process.This violates the intended post-exec access restrictions and couldexpose sensitive memory addresses or be used as a primitive in a largerexploit chain. Consequently, the race can lead to unauthorizeddisclosure of information across privilege boundaries and poses apotential security risk.Take a read lock on signal->exec_update_lock prior to invokingptrace_may_access() and accessing the robust_list/compat_robust_list.This ensures that the target task's exec state remains stable during thecheck, allowing for consistent and synchronized validation ofcredentials.

The currentlogic uses !PTR_ERR_OR_ZERO(cpu_clk) which evaluates to true for bothvalid pointers and NULL, leading to potential NULL pointer dereferencein clk_get_rate().Per include/linux/err.h documentation, PTR_ERR_OR_ZERO(ptr) returns:"The error code within @ptr if it is an error pointer; 0 otherwise."This means PTR_ERR_OR_ZERO() returns 0 for both valid pointers AND NULLpointers. Therefore !PTR_ERR_OR_ZERO(cpu_clk) evaluates to true (proceed)when cpu_clk is either valid or NULL, causing clk_get_rate(NULL) to becalled when of_clk_get() returns NULL.Replace with !IS_ERR_OR_NULL(cpu_clk) which only proceeds for validpointers, preventing potential NULL pointer dereference in clk_get_rate().

Description: In the Linux kernel, the following vulnerability has been resolved:x86/fpu: Ensure XFD state on signal deliverySean reported [1] the following splat when running KVM tests: WARNING: CPU: 232 PID: 15391 at xfd_validate_state+0x65/0x70 Call Trace: fpu__clear_user_states+0x9c/0x100 arch_do_signal_or_restart+0x142/0x210 exit_to_user_mode_loop+0x55/0x100 do_syscall_64+0x205/0x2c0 entry_SYSCALL_64_after_hwframe+0x4b/0x53Chao further identified [2] a reproducible scenario involving signaldelivery: a non-AMX task is preempted by an AMX-enabled task whichmodifies the XFD MSR.When the non-AMX task resumes and reloads XSTATE with init values,a warning is triggered due to a mismatch between fpstate::xfd and theCPU's current XFD state. fpu__clear_user_states() does not currentlyre-synchronize the XFD state after such preemption.Invoke xfd_update_state() which detects and corrects the mismatch ifthere is a dynamic feature.This also benefits the sigreturn path, as fpu__restore_sig() may callfpu__clear_user_states() when the sigframe is inaccessible.[ dhansen: minor changelog munging ]

CVE-2025-68211 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ksm: use range-walk function to jump over holes in scan_get_next_rmap_itemCurrently, scan_get_next_rmap_item() walks every page address in a VMA tolocate mergeable pages. This becomes highly inefficient when scanninglarge virtual memory areas that contain mostly unmapped regions, causingksmd to use large amount of cpu without deduplicating much pages.This patch replaces the per-address lookup with a range walk usingwalk_page_range(). The range walker allows KSM to skip over entireunmapped holes in a VMA, avoiding unnecessary lookups. This problem waspreviously discussed in [1].Consider the following test program which creates a 32 TiB mapping in thevirtual address space but only populates a single page:#include #include #include /* 32 TiB */const size_t size = 32ul * 1024 * 1024 * 1024 * 1024;int main() { char *area = mmap(NULL, size, PROT_READ | PROT_WRITE, MAP_NORESERVE | MAP_PRIVATE | MAP_ANON, -1, 0); if (area == MAP_FAILED) { perror("mmap() failed\n"); return -1; } /* Populate a single page such that we get an anon_vma. */ *area = 0; /* Enable KSM. */ madvise(area, size, MADV_MERGEABLE); pause(); return 0;}$ ./ksm-sparse &$ echo 1 > /sys/kernel/mm/ksm/run Without this patch ksmd uses 100% of the cpu for a long time (more then 1hour in my test machine) scanning all the 32 TiB virtual address spacethat contain only one mapped page. This makes ksmd essentially deadlockednot able to deduplicate anything of value. With this patch ksmd walksonly the one mapped page and skips the rest of the 32 TiB virtual addressspace, making the scan fast using little cpu.

CVE-2025-68214 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:timers: Fix NULL function pointer race in timer_shutdown_sync()There is a race condition between timer_shutdown_sync() and timerexpiration that can lead to hitting a WARN_ON in expire_timers().The issue occurs when timer_shutdown_sync() clears the timer functionto NULL while the timer is still running on another CPU. The racescenario looks like this:CPU0 CPU1 lock_timer_base() expire_timers() base->running_timer = timer; unlock_timer_base() [call_timer_fn enter] mod_timer() ...timer_shutdown_sync()lock_timer_base()// For now, will not detach the timer but only clear its function to NULLif (base->running_timer != timer) ret = detach_if_pending(timer, base, true);if (shutdown) timer->function = NULL;unlock_timer_base() [call_timer_fn exit] lock_timer_base() base->running_timer = NULL; unlock_timer_base() ... // Now timer is pending while its function set to NULL. // next timer trigger expire_timers() WARN_ON_ONCE(!fn) // hit ...lock_timer_base()// Now timer will detachif (base->running_timer != timer) ret = detach_if_pending(timer, base, true);if (shutdown) timer->function = NULL;unlock_timer_base()The problem is that timer_shutdown_sync() clears the timer functionregardless of whether the timer is currently running. This can leave apending timer with a NULL function pointer, which triggers theWARN_ON_ONCE(!fn) check in expire_timers().Fix this by only clearing the timer function when actually detaching thetimer. If the timer is running, leave the function pointer intact, which issafe because the timer will be properly detached when it finishes running.

CVE-2025-68219 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:cifs: fix memory leak in smb3_fs_context_parse_param error pathAdd proper cleanup of ctx->source and fc->source to thecifs_parse_mount_err error handler. This ensures that memory allocatedfor the source strings is correctly freed on all error paths, matchingthe cleanup already performed in the success path bysmb3_cleanup_fs_context_contents().Pointers are also set to NULL after freeing to prevent potentialdouble-free issues.This change fixes a memory leak originally detected by syzbot. Theleak occurred when processing Opt_source mount options if an errorhappened after ctx->source and fc->source were successfullyallocated but before the function completed.The specific leak sequence was:1. ctx->source = smb3_fs_context_fullpath(ctx, '/') allocates memory2. fc->source = kstrdup(ctx->source, GFP_KERNEL) allocates more memory3. A subsequent error jumps to cifs_parse_mount_err4. The old error handler freed passwords but not the source strings,causing the memory to leak.This issue was not addressed by commit e8c73eb7db0a ("cifs: client:fix memory leak in smb3_fs_context_parse_param"), which only fixedleaks from repeated fsconfig() calls but not this error path.Patch updated with minor change suggested by kernel test robot

Description: In the Linux kernel, the following vulnerability has been resolved:binfmt_misc: restore write access before closing files opened by open_exec()bm_register_write() opens an executable file using open_exec(), whichinternally calls do_open_execat() and denies write access on the file toavoid modification while it is being executed.However, when an error occurs, bm_register_write() closes the file usingfilp_close() directly. This does not restore the write permission, whichmay cause subsequent write operations on the same file to fail.Fix this by calling exe_file_allow_write_access() before filp_close() torestore the write permission properly.

Description: In the Linux kernel, the following vulnerability has been resolved:net: netpoll: fix incorrect refcount handling causing incorrect cleanupcommit efa95b01da18 ("netpoll: fix use after free") incorrectlyignored the refcount and prematurely set dev->npinfo to NULL duringnetpoll cleanup, leading to improper behavior and memory leaks.Scenario causing lack of proper cleanup:1) A netpoll is associated with a NIC (e.g., eth0) and netdev->npinfo is allocated, and refcnt = 1 - Keep in mind that npinfo is shared among all netpoll instances. In this case, there is just one.2) Another netpoll is also associated with the same NIC and npinfo->refcnt += 1. - Now dev->npinfo->refcnt = 2; - There is just one npinfo associated to the netdev.3) When the first netpolls goes to clean up: - The first cleanup succeeds and clears np->dev->npinfo, ignoring refcnt. - It basically calls `RCU_INIT_POINTER(np->dev->npinfo, NULL);` - Set dev->npinfo = NULL, without proper cleanup - No ->ndo_netpoll_cleanup() is either called4) Now the second target tries to clean up - The second cleanup fails because np->dev->npinfo is already NULL. * In this case, ops->ndo_netpoll_cleanup() was never called, and the skb pool is not cleaned as well (for the second netpoll instance) - This leaks npinfo and skbpool skbs, which is clearly reported by kmemleak.Revert commit efa95b01da18 ("netpoll: fix use after free") and addsclarifying comments emphasizing that npinfo cleanup should only happenonce the refcount reaches zero, ensuring stable and correct netpollbehavior.

Callingput_device(&mdev->dev) there triggers a device core WARN and ends upinvoking kref_put(&kobj->kref, kobject_release) on an uninitializedkobject.In this path the private struct was only kmalloc'ed and the intendedrelease is effectively kfree(mdev) anyway, so free it directly insteadof calling put_device() on an uninitialized device.This removes the WARNING and fixes the pre-initialization error path.

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: check device's attached status in compat ioctlsSyzbot identified an issue [1] that crashes kernel, seemingly due tounexistent callback dev->get_valid_routes(). By all means, this shouldnot occur as said callback must always be set toget_zero_valid_routes() in __comedi_device_postconfig().As the crash seems to appear exclusively in i386 kernels, at least,judging from [1] reports, the blame lies with compat versionsof standard IOCTL handlers. Several of them are modified anddo not use comedi_unlocked_ioctl(). While functionality of theseioctls essentially copy their original versions, they do nothave required sanity check for device's attached status. This,in turn, leads to a possibility of calling select IOCTLs on adevice that has not been properly setup, even via COMEDI_DEVCONFIG.Doing so on unconfigured devices means that several crucial stepsare missed, for instance, specifying dev->get_valid_routes()callback.Fix this somewhat crudely by ensuring device's attached status beforeperforming any ioctls, improving logic consistency between modernand compat functions.[1] Syzbot report:BUG: kernel NULL pointer dereference, address: 0000000000000000...CR2: ffffffffffffffd6 CR3: 000000006c717000 CR4: 0000000000352ef0Call Trace: get_valid_routes drivers/comedi/comedi_fops.c:1322 [inline] parse_insn+0x78c/0x1970 drivers/comedi/comedi_fops.c:1401 do_insnlist_ioctl+0x272/0x700 drivers/comedi/comedi_fops.c:1594 compat_insnlist drivers/comedi/comedi_fops.c:3208 [inline] comedi_compat_ioctl+0x810/0x990 drivers/comedi/comedi_fops.c:3273 __do_compat_sys_ioctl fs/ioctl.c:695 [inline] __se_compat_sys_ioctl fs/ioctl.c:638 [inline] __ia32_compat_sys_ioctl+0x242/0x370 fs/ioctl.c:638 do_syscall_32_irqs_on arch/x86/entry/syscall_32.c:83 [inline]...

CVE-2025-68282 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: udc: fix use-after-free in usb_gadget_state_workA race condition during gadget teardown can lead to a use-after-freein usb_gadget_state_work(), as reported by KASAN: BUG: KASAN: invalid-access in sysfs_notify+0x2c/0xd0 Workqueue: events usb_gadget_state_workThe fundamental race occurs because a concurrent event (e.g., aninterrupt) can call usb_gadget_set_state() and schedule gadget->workat any time during the cleanup process in usb_del_gadget().Commit 399a45e5237c ("usb: gadget: core: flush gadget workqueue afterdevice removal") attempted to fix this by moving flush_work() to afterdevice_del(). However, this does not fully solve the race, as a newwork item can still be scheduled *after* flush_work() completes butbefore the gadget's memory is freed, leading to the same use-after-free.This patch fixes the race condition robustly by introducing a 'teardown'flag and a 'state_lock' spinlock to the usb_gadget struct. The flag isset during cleanup in usb_del_gadget() *before* calling flush_work() toprevent any new work from being scheduled once cleanup has commenced.The scheduling site, usb_gadget_set_state(), now checks this flag underthe lock before queueing the work, thus safely closing the race window.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: dwc3: Fix race condition between concurrent dwc3_remove_requests() call pathsThis patch addresses a race condition caused by unsynchronizedexecution of multiple call paths invoking `dwc3_remove_requests()`,leading to premature freeing of USB requests and subsequent crashes.Three distinct execution paths interact with `dwc3_remove_requests()`:Path 1:Triggered via `dwc3_gadget_reset_interrupt()` during USB resethandling. The call stack includes:- `dwc3_ep0_reset_state()`- `dwc3_ep0_stall_and_restart()`- `dwc3_ep0_out_start()`- `dwc3_remove_requests()`- `dwc3_gadget_del_and_unmap_request()`Path 2:Also initiated from `dwc3_gadget_reset_interrupt()`, but through`dwc3_stop_active_transfers()`. The call stack includes:- `dwc3_stop_active_transfers()`- `dwc3_remove_requests()`- `dwc3_gadget_del_and_unmap_request()`Path 3:Occurs independently during `adb root` execution, which triggersUSB function unbind and bind operations. The sequence includes:- `gserial_disconnect()`- `usb_ep_disable()`- `dwc3_gadget_ep_disable()`- `dwc3_remove_requests()` with `-ESHUTDOWN` statusPath 3 operates asynchronously and lacks synchronization with Paths1 and 2. When Path 3 completes, it disables endpoints and frees 'out'requests. If Paths 1 or 2 are still processing these requests,accessing freed memory leads to a crash due to use-after-free conditions.To fix this added check for request completion and skip processingif already completed and added the request status for ep0 while queue.

CVE-2025-68296 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:drm, fbcon, vga_switcheroo: Avoid race condition in fbcon setupProtect vga_switcheroo_client_fb_set() with console lock. Avoids OOBaccess in fbcon_remap_all(). Without holding the console lock the callraces with switching outputs.VGA switcheroo calls fbcon_remap_all() when switching clients. The fbconfunction uses struct fb_info.node, which is set by register_framebuffer().As the fb-helper code currently sets up VGA switcheroo before registeringthe framebuffer, the value of node is -1 and therefore not a legal value.For example, fbcon uses the value within set_con2fb_map() [1] as an indexinto an array.Moving vga_switcheroo_client_fb_set() after register_framebuffer() canresult in VGA switching that does not switch fbcon correctly.Therefore move vga_switcheroo_client_fb_set() under fbcon_fb_registered(),which already holds the console lock. Fbdev calls fbcon_fb_registered()from within register_framebuffer(). Serializes the helper with VGAswitcheroo's call to fbcon_remap_all().Although vga_switcheroo_client_fb_set() takes an instance of struct fb_infoas parameter, it really only needs the contained fbcon state. Moving thecall to fbcon initialization is therefore cleaner than before. Only amdgpu,i915, nouveau and radeon support vga_switcheroo. For all other drivers,this change does nothing.

Description: In the Linux kernel, the following vulnerability has been resolved:can: kvaser_usb: leaf: Fix potential infinite loop in command parsersThe `kvaser_usb_leaf_wait_cmd()` and `kvaser_usb_leaf_read_bulk_callback`functions contain logic to zero-length commands. These commands are usedto align data to the USB endpoint's wMaxPacketSize boundary.The driver attempts to skip these placeholders by aligning the bufferposition `pos` to the next packet boundary using `round_up()` function.However, if zero-length command is found exactly on a packet boundary(i.e., `pos` is a multiple of wMaxPacketSize, including 0), `round_up`function will return the unchanged value of `pos`. This prevents `pos`to be increased, causing an infinite loop in the parsing logic.This patch fixes this in the function by using `pos + 1` instead.This ensures that even if `pos` is on a boundary, the calculation isbased on `pos + 1`, forcing `round_up()` to always return the nextaligned boundary.

Description: In the Linux kernel, the following vulnerability has been resolved:usbnet: Prevents free active keventThe root cause of this issue are:1. When probing the usbnet device, executing usbnet_link_change(dev, 0, 0);put the kevent work in global workqueue. However, the kevent has not yetbeen scheduled when the usbnet device is unregistered. Therefore, executingfree_netdev() results in the "free active object (kevent)" error reportedhere.2. Another factor is that when calling usbnet_disconnect()->unregister_netdev(),if the usbnet device is up, ndo_stop() is executed to cancel the kevent.However, because the device is not up, ndo_stop() is not executed.The solution to this problem is to cancel the kevent before executingfree_netdev().

There have been many inconsistencies in the file systemdata.In the case of file system data inconsistency, for example, if the blockbitmap of a referenced block is not set, it can lead to the situation wherea block being committed is allocated and used again. As a result, thefollowing condition will not be satisfied then trigger BUG_ON. Of course,it is entirely possible to construct a problematic image that can triggerthis BUG_ON through specific operations. In fact, I have constructed suchan image and easily reproduced this issue.Therefore, J_ASSERT() holds true only under ideal conditions, but it maynot necessarily be satisfied in exceptional scenarios. Using J_ASSERT()directly in abnormal situations would cause the system to crash, which isclearly not what we want. So here we directly trigger a JBD abort insteadof immediately invoking BUG_ON.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix racy bitfield write in btrfs_clear_space_info_full()From the memory-barriers.txt document regarding memory barrier orderingguarantees: (*) These guarantees do not apply to bitfields, because compilers often generate code to modify these using non-atomic read-modify-write sequences. Do not attempt to use bitfields to synchronize parallel algorithms. (*) Even in cases where bitfields are protected by locks, all fields in a given bitfield must be protected by one lock. If two fields in a given bitfield are protected by different locks, the compiler's non-atomic read-modify-write sequences can cause an update to one field to corrupt the value of an adjacent field.btrfs_space_info has a bitfield sharing an underlying word consisting ofthe fields full, chunk_alloc, and flush:struct btrfs_space_info { struct btrfs_fs_info * fs_info; /* 0 8 */ struct btrfs_space_info * parent; /* 8 8 */ ... int clamp; /* 172 4 */ unsigned int full:1; /* 176: 0 4 */ unsigned int chunk_alloc:1; /* 176: 1 4 */ unsigned int flush:1; /* 176: 2 4 */ ...Therefore, to be safe from parallel read-modify-writes losing a write toone of the bitfield members protected by a lock, all writes to all thebitfields must use the lock. They almost universally do, except forbtrfs_clear_space_info_full() which iterates over the space_infos andwrites out found->full = 0 without a lock.Imagine that we have one thread completing a transaction in which wefinished deleting a block_group and are thus callingbtrfs_clear_space_info_full() while simultaneously the data reclaimticket infrastructure is running do_async_reclaim_data_space(): T1 T2btrfs_commit_transaction btrfs_clear_space_info_full data_sinfo->full = 0 READ: full:0, chunk_alloc:0, flush:1 do_async_reclaim_data_space(data_sinfo) spin_lock(&space_info->lock); if(list_empty(tickets)) space_info->flush = 0; READ: full: 0, chunk_alloc:0, flush:1 MOD/WRITE: full: 0, chunk_alloc:0, flush:0 spin_unlock(&space_info->lock); return; MOD/WRITE: full:0, chunk_alloc:0, flush:1and now data_sinfo->flush is 1 but the reclaim worker has exited. Thisbreaks the invariant that flush is 0 iff there is no work queued orrunning. Once this invariant is violated, future allocations that gointo __reserve_bytes() will add tickets to space_info->tickets but willsee space_info->flush is set to 1 and not queue the work. After this,they will block forever on the resulting ticket, as it is now impossibleto kick the worker again.I also confirmed by looking at the assembly of the affected kernel thatit is doing RMW operations. For example, to set the flush (3rd) bit to 0,the assembly is: andb $0xfb,0x60(%rbx)and similarly for setting the full (1st) bit to 0: andb $0xfe,-0x20(%rax)So I think this is really a bug on practical systems. I have observeda number of systems in this exact state, but am currently unable toreproduce it.Rather than leaving this footgun lying around for the future, takeadvantage of the fact that there is room in the struct anyway, and thatit is already quite large and simply change the three bitfield members tobools. This avoids writes to space_info->full having any effect on---truncated---

CVE-2025-68725 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Do not let BPF test infra emit invalid GSO types to stackYinhao et al. reported that their fuzzer tool was able to trigger askb_warn_bad_offload() from netif_skb_features() -> gso_features_check().When a BPF program - triggered via BPF test infra - pushes the packetto the loopback device via bpf_clone_redirect() then mentioned offloadwarning can be seen. GSO-related features are then rightfully disabled.We get into this situation due to convert___skb_to_skb() settinggso_segs and gso_size but not gso_type. Technically, it makes sensethat this warning triggers since the GSO properties are malformed dueto the gso_type. Potentially, the gso_type could be marked non-trustworthythrough setting it at least to SKB_GSO_DODGY without any other specificassumptions, but that also feels wrong given we should not go furtherinto the GSO engine in the first place.The checks were added in 121d57af308d ("gso: validate gso_type in GSOhandlers") because there were malicious (syzbot) senders that combinea protocol with a non-matching gso_type. If we would want to drop suchpackets, gso_features_check() currently only returns feature flags vianetif_skb_features(), so one location for potentially dropping such skbscould be validate_xmit_unreadable_skb(), but then otoh it would bean additional check in the fast-path for a very corner case. Givenbpf_clone_redirect() is the only place where BPF test infra could emitsuch packets, lets reject them right there.

CVE-2025-68740 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ima: Handle error code returned by ima_filter_rule_match()In ima_match_rules(), if ima_filter_rule_match() returns -ENOENT due tothe rule being NULL, the function incorrectly skips the 'if (!rc)' checkand sets 'result = true'. The LSM rule is considered a match, causingextra files to be measured by IMA.This issue can be reproduced in the following scenario:After unloading the SELinux policy module via 'semodule -d', if an IMAmeasurement is triggered before ima_lsm_rules is updated,in ima_match_rules(), the first call to ima_filter_rule_match() returns-ESTALE. This causes the code to enter the 'if (rc == -ESTALE &&!rule_reinitialized)' block, perform ima_lsm_copy_rule() and retry. Inima_lsm_copy_rule(), since the SELinux module has been removed, the rulebecomes NULL, and the second call to ima_filter_rule_match() returns-ENOENT. This bypasses the 'if (!rc)' check and results in a false match.Call trace: selinux_audit_rule_match+0x310/0x3b8 security_audit_rule_match+0x60/0xa0 ima_match_rules+0x2e4/0x4a0 ima_match_policy+0x9c/0x1e8 ima_get_action+0x48/0x60 process_measurement+0xf8/0xa98 ima_bprm_check+0x98/0xd8 security_bprm_check+0x5c/0x78 search_binary_handler+0x6c/0x318 exec_binprm+0x58/0x1b8 bprm_execve+0xb8/0x130 do_execveat_common.isra.0+0x1a8/0x258 __arm64_sys_execve+0x48/0x68 invoke_syscall+0x50/0x128 el0_svc_common.constprop.0+0xc8/0xf0 do_el0_svc+0x24/0x38 el0_svc+0x44/0x200 el0t_64_sync_handler+0x100/0x130 el0t_64_sync+0x3c8/0x3d0Fix this by changing 'if (!rc)' to 'if (rc <= 0)' to ensure that errorcodes like -ENOENT do not bypass the check and accidentally result in asuccessful match.

According to [2], the reserved field was explicitly initializedwith 0, and that field must remain 0 as long as reserved. Therefore, whenthe "mode" field is not 0 (i.e. no longer reserved), the file must beS_IFDIR if dir == 1, and the file must be one of S_IFREG/S_IFLNK/S_IFCHR/S_IFBLK/S_IFIFO/S_IFSOCK if dir == 0.

CVE-2025-68780 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:sched/deadline: only set free_cpus for online runqueuesCommit 16b269436b72 ("sched/deadline: Modify cpudl::free_cpusto reflect rd->online") introduced the cpudl_set/clear_freecpufunctions to allow the cpu_dl::free_cpus mask to be manipulatedby the deadline scheduler class rq_on/offline callbacks so themask would also reflect this state.Commit 9659e1eeee28 ("sched/deadline: Remove cpu_active_maskfrom cpudl_find()") removed the check of the cpu_active_mask tosave some processing on the premise that the cpudl::free_cpusmask already reflected the runqueue online state.Unfortunately, there are cases where it is possible for thecpudl_clear function to set the free_cpus bit for a CPU when thedeadline runqueue is offline. When this occurs while a CPU isconnected to the default root domain the flag may retain the badstate after the CPU has been unplugged. Later, a different CPUthat is transitioning through the default root domain may push adeadline task to the powered down CPU when cpudl_find sees itsfree_cpus bit is set. If this happens the task will not have theopportunity to run.One example is outlined here:https://lore.kernel.org/lkml/20250110233010.2339521-1-opendmb@gmail.comAnother occurs when the last deadline task is migrated from aCPU that has an offlined runqueue. The dequeue_task member ofthe deadline scheduler class will eventually call cpudl_clearand set the free_cpus bit for the CPU.This commit modifies the cpudl_clear function to be aware of theonline state of the deadline runqueue so that the free_cpus maskcan be updated appropriately.It is no longer necessary to manage the mask outside of thecpudl_set/clear functions so the cpudl_set/clear_freecpufunctions are removed. In addition, since the free_cpus mask isnow only updated under the cpudl lock the code was changed touse the non-atomic __cpumask functions.

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-mixer: us16x08: validate meter packet indicesget_meter_levels_from_urb() parses the 64-byte meter packets sent bythe device and fills the per-channel arrays meter_level[],comp_level[] and master_level[] in struct snd_us16x08_meter_store.Currently the function derives the channel index directly from themeter packet (MUB2(meter_urb, s) - 1) and uses it to index thosearrays without validating the range. If the packet contains anegative or out-of-range channel number, the driver may write pastthe end of these arrays.Introduce a local channel variable and validate it before updating thearrays. We reject negative indices, limit meter_level[] andcomp_level[] to SND_US16X08_MAX_CHANNELS, and guard master_level[]updates with ARRAY_SIZE(master_level).

However, the functionunconditionally executes readb(apbs[IndexCard].RamIO + VERS) at theend.If cmd is 6, IndexCard may reference a board that does not exist(where RamIO is NULL), leading to a NULL pointer dereference.Fix this by skipping the readb access when cmd is 6, as thiscommand is a global information query and does not target a specificboard context.

Description: In the Linux kernel, the following vulnerability has been resolved:media: vidtv: initialize local pointers upon transfer of memory ownershipvidtv_channel_si_init() creates a temporary list (program, service, event)and ownership of the memory itself is transferred to the PAT/SDT/EITtables through vidtv_psi_pat_program_assign(),vidtv_psi_sdt_service_assign(), vidtv_psi_eit_event_assign().The problem here is that the local pointer where the memory ownershiptransfer was completed is not initialized to NULL. This causes thevidtv_psi_pmt_create_sec_for_each_pat_entry() function to fail, andin the flow that jumps to free_eit, the memory that was freed byvidtv_psi_*_table_destroy() can be accessed again byvidtv_psi_*_event_destroy() due to the uninitialized local pointer, so itis freed once again.Therefore, to prevent use-after-free and double-free vulnerability,local pointers must be initialized to NULL when transferring memoryownership.

Without proper validation, badfirmware could provide format strings with invalid format specifiers(e.g., %s, %p, %n) that could lead to crashes, or other undefinedbehavior.Add mlx5_tracer_validate_params() to validate that all format specifiersin trace strings are limited to safe integer/hex formats (%x, %d, %i,%u, %llx, %lx, etc.). Reject strings containing other format types thatcould be used to access arbitrary memory or cause crashes.Invalid format strings are added to the trace output for visibility with"BAD_FORMAT: " prefix.

During device detachment, the original implementationcalls flush_workqueue() in psmouse_disconnect() to ensurecompletion of dev3_register_work. However, the flush_workqueue()in psmouse_disconnect() only blocks and waits for work items thatwere already queued to the workqueue prior to its invocation. Anywork items submitted after flush_workqueue() is called are notincluded in the set of tasks that the flush operation awaits.This means that after flush_workqueue() has finished executing,the dev3_register_work could still be scheduled. Although thepsmouse state is set to PSMOUSE_CMD_MODE in psmouse_disconnect(),the scheduling of dev3_register_work remains unaffected.The race condition can occur as follows:CPU 0 (cleanup path) | CPU 1 (delayed work)psmouse_disconnect() | psmouse_set_state() | flush_workqueue() | alps_report_bare_ps2_packet() alps_disconnect() | psmouse_queue_work() kfree(priv); // FREE | alps_register_bare_ps2_mouse() | priv = container_of(work...); // USE | priv->dev3 // USEAdd disable_delayed_work_sync() in alps_disconnect() to ensurethat dev3_register_work is properly canceled and prevented fromexecuting after the alps_data structure has been deallocated.This bug is identified by static analysis.

Description: In the Linux kernel, the following vulnerability has been resolved:net: hns3: using the num_tqps in the vf driver to apply for resourcesCurrently, hdev->htqp is allocated using hdev->num_tqps, and kinfo->tqpis allocated using kinfo->num_tqps. However, kinfo->num_tqps is set tomin(new_tqps, hdev->num_tqps); Therefore, kinfo->num_tqps may be smallerthan hdev->num_tqps, which causes some hdev->htqp[i] to remainuninitialized in hclgevf_knic_setup().Thus, this patch allocates hdev->htqp and kinfo->tqp using hdev->num_tqps,ensuring that the lengths of hdev->htqp and kinfo->tqp are consistentand that all elements are properly initialized.

Description: In the Linux kernel, the following vulnerability has been resolved:powerpc/64s/slb: Fix SLB multihit issue during SLB preloadOn systems using the hash MMU, there is a software SLB preload cache thatmirrors the entries loaded into the hardware SLB buffer. This preloadcache is subject to periodic eviction - typically after every 256 contextswitches - to remove old entry.To optimize performance, the kernel skips switch_mmu_context() inswitch_mm_irqs_off() when the prev and next mm_struct are the same.However, on hash MMU systems, this can lead to inconsistencies betweenthe hardware SLB and the software preload cache.If an SLB entry for a process is evicted from the software cache on oneCPU, and the same process later runs on another CPU without executingswitch_mmu_context(), the hardware SLB may retain stale entries. If thekernel then attempts to reload that entry, it can trigger an SLBmulti-hit error.The following timeline shows how stale SLB entries are created and cancause a multi-hit error when a process moves between CPUs without aMMU context switch.CPU 0 CPU 1----- -----Process Pexec swapper/1 load_elf_binary begin_new_exc activate_mm switch_mm_irqs_off switch_mmu_context switch_slb /* * This invalidates all * the entries in the HW * and setup the new HW * SLB entries as per the * preload cache. */context_switchsched_migrate_task migrates process P to cpu-1Process swapper/0 context switch (to process P)(uses mm_struct of Process P) switch_mm_irqs_off() switch_slb load_slb++ /* * load_slb becomes 0 here * and we evict an entry from * the preload cache with * preload_age().

Description: In the Linux kernel, the following vulnerability has been resolved:dm-verity: disable recursive forward error correctionThere are two problems with the recursive correction:1. It may cause denial-of-service. In fec_read_bufs, there is a loop thathas 253 iterations. For each iteration, we may call verity_hash_for_blockrecursively. There is a limit of 4 nested recursions - that means thatthere may be at most 253^4 (4 billion) iterations. Red Hat QE teamactually created an image that pushes dm-verity to this limit - and thisimage just makes the udev-worker process get stuck in the 'D' state.2. It doesn't work. In fec_read_bufs we store data into the variable"fio->bufs", but fio bufs is shared between recursive invocations, if"verity_hash_for_block" invoked correction recursively, it wouldoverwrite partially filled fio->bufs.

CVE-2025-71162 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:dmaengine: tegra-adma: Fix use-after-freeA use-after-free bug exists in the Tegra ADMA driver when audio streamsare terminated, particularly during XRUN conditions. The issue occurswhen the DMA buffer is freed by tegra_adma_terminate_all() before thevchan completion tasklet finishes accessing it.The race condition follows this sequence: 1. DMA transfer completes, triggering an interrupt that schedules the completion tasklet (tasklet has not executed yet) 2. Audio playback stops, calling tegra_adma_terminate_all() which frees the DMA buffer memory via kfree() 3. The scheduled tasklet finally executes, calling vchan_complete() which attempts to access the already-freed memorySince tasklets can execute at any time after being scheduled, there isno guarantee that the buffer will remain valid when vchan_complete()runs.Fix this by properly synchronizing the virtual channel completion: - Calling vchan_terminate_vdesc() in tegra_adma_stop() to mark the descriptors as terminated instead of freeing the descriptor. - Add the callback tegra_adma_synchronize() that calls vchan_synchronize() which kills any pending tasklets and frees any terminated descriptors.Crash logs:[ 337.427523] BUG: KASAN: use-after-free in vchan_complete+0x124/0x3b0[ 337.427544] Read of size 8 at addr ffff000132055428 by task swapper/0/0[ 337.427562] Call trace:[ 337.427564] dump_backtrace+0x0/0x320[ 337.427571] show_stack+0x20/0x30[ 337.427575] dump_stack_lvl+0x68/0x84[ 337.427584] print_address_description.constprop.0+0x74/0x2b8[ 337.427590] kasan_report+0x1f4/0x210[ 337.427598] __asan_load8+0xa0/0xd0[ 337.427603] vchan_complete+0x124/0x3b0[ 337.427609] tasklet_action_common.constprop.0+0x190/0x1d0[ 337.427617] tasklet_action+0x30/0x40[ 337.427623] __do_softirq+0x1a0/0x5c4[ 337.427628] irq_exit+0x110/0x140[ 337.427633] handle_domain_irq+0xa4/0xe0[ 337.427640] gic_handle_irq+0x64/0x160[ 337.427644] call_on_irq_stack+0x20/0x4c[ 337.427649] do_interrupt_handler+0x7c/0x90[ 337.427654] el1_interrupt+0x30/0x80[ 337.427659] el1h_64_irq_handler+0x18/0x30[ 337.427663] el1h_64_irq+0x7c/0x80[ 337.427667] cpuidle_enter_state+0xe4/0x540[ 337.427674] cpuidle_enter+0x54/0x80[ 337.427679] do_idle+0x2e0/0x380[ 337.427685] cpu_startup_entry+0x2c/0x70[ 337.427690] rest_init+0x114/0x130[ 337.427695] arch_call_rest_init+0x18/0x24[ 337.427702] start_kernel+0x380/0x3b4[ 337.427706] __primary_switched+0xc0/0xc8

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: always detect conflicting inodes when logging inode refsAfter rename exchanging (either with the rename exchange operation orregular renames in multiple non-atomic steps) two inodes and at leastone of them is a directory, we can end up with a log tree that containsonly of the inodes and after a power failure that can result in an attemptto delete the other inode when it should not because it was not deletedbefore the power failure. In some case that delete attempt fails whenthe target inode is a directory that contains a subvolume inside it, sincethe log replay code is not prepared to deal with directory entries thatpoint to root items (only inode items).1) We have directories "dir1" (inode A) and "dir2" (inode B) under the same parent directory;2) We have a file (inode C) under directory "dir1" (inode A);3) We have a subvolume inside directory "dir2" (inode B);4) All these inodes were persisted in a past transaction and we are currently at transaction N;5) We rename the file (inode C), so at btrfs_log_new_name() we update inode C's last_unlink_trans to N;6) We get a rename exchange for "dir1" (inode A) and "dir2" (inode B), so after the exchange "dir1" is inode B and "dir2" is inode A. During the rename exchange we call btrfs_log_new_name() for inodes A and B, but because they are directories, we don't update their last_unlink_trans to N;7) An fsync against the file (inode C) is done, and because its inode has a last_unlink_trans with a value of N we log its parent directory (inode A) (through btrfs_log_all_parents(), called from btrfs_log_inode_parent()).8) So we end up with inode B not logged, which now has the old name of inode A. At copy_inode_items_to_log(), when logging inode A, we did not check if we had any conflicting inode to log because inode A has a generation lower than the current transaction (created in a past transaction);9) After a power failure, when replaying the log tree, since we find that inode A has a new name that conflicts with the name of inode B in the fs tree, we attempt to delete inode B... this is wrong since that directory was never deleted before the power failure, and because there is a subvolume inside that directory, attempting to delete it will fail since replay_dir_deletes() and btrfs_unlink_inode() are not prepared to deal with dir items that point to roots instead of inodes. When that happens the mount fails and we get a stack trace like the following: [87.2314] BTRFS info (device dm-0): start tree-log replay [87.2318] BTRFS critical (device dm-0): failed to delete reference to subvol, root 5 inode 256 parent 259 [87.2332] ------------[ cut here ]------------ [87.2338] BTRFS: Transaction aborted (error -2) [87.2346] WARNING: CPU: 1 PID: 638968 at fs/btrfs/inode.c:4345 __btrfs_unlink_inode+0x416/0x440 [btrfs] [87.2368] Modules linked in: btrfs loop dm_thin_pool (...)

CVE-2025-71184 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix NULL dereference on root when tracing inode evictionWhen evicting an inode the first thing we do is to setup tracing for it,which implies fetching the root's id. But in btrfs_evict_inode() theroot might be NULL, as implied in the next check that we do inbtrfs_evict_inode().Hence, we either should set the ->root_objectid to 0 in case the root isNULL, or we move tracing setup after checking that the root is notNULL. Setting the rootid to 0 at least gives us the possibility to tracethis call even in the case when the root is NULL, so that's the solutiontaken here.

CVE-2025-71237 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: Fix potential block overflow that cause system hangWhen a user executes the FITRIM command, an underflow can occur whencalculating nblocks if end_block is too small. Since nblocks is oftype sector_t, which is u64, a negative nblocks value will become avery large positive integer. This ultimately leads to the block layerfunction __blkdev_issue_discard() taking an excessively long time toprocess the bio chain, and the ns_segctor_sem lock remains held for along period. This prevents other tasks from acquiring the ns_segctor_semlock, resulting in the hang reported by syzbot in [1].If the ending block is too small, typically if it is smaller than 4KiBrange, depending on the usage of the segment 0, it may be possible toattempt a discard request beyond the device size causing the hang.Exiting successfully and assign the discarded size (0 in this case)to range->len.Although the start and len values in the user input range are too small,a conservative strategy is adopted here to safely ignore them, which isequivalent to a no-op; it will not perform any trimming and will notthrow an error.[1]task:segctord state:D stack:28968 pid:6093 tgid:6093 ppid:2 task_flags:0x200040 flags:0x00080000Call Trace: rwbase_write_lock+0x3dd/0x750 kernel/locking/rwbase_rt.c:272 nilfs_transaction_lock+0x253/0x4c0 fs/nilfs2/segment.c:357 nilfs_segctor_thread_construct fs/nilfs2/segment.c:2569 [inline] nilfs_segctor_thread+0x6ec/0xe00 fs/nilfs2/segment.c:2684[ryusuke: corrected part of the commit message about the consequences]

This happenswhen:1. one QFQ qdisc is attached to the dev as the root qdisc, and2. another QFQ qdisc is temporarily referenced (e.g., via qdisc_get()/ qdisc_put()) and is pending to be destroyed, as in functiontc_new_tfilter.When packets are enqueued through the root QFQ qdisc, the sharedleaf_qdisc->q.qlen increases. At the same time, the second QFQqdisc triggers qdisc_put and qdisc_destroy: the qdisc entersqfq_reset() with its own q->q.qlen == 0, but its class's leafqdisc->q.qlen > 0. Therefore, the qfq_reset would wrongly deactivatean inactive aggregate and trigger a null-deref in qfq_deactivate_agg:[ 0.903172] BUG: kernel NULL pointer dereference, address: 0000000000000000[ 0.903571] #PF: supervisor write access in kernel mode[ 0.903860] #PF: error_code(0x0002) - not-present page[ 0.904177] PGD 10299b067 P4D 10299b067 PUD 10299c067 PMD 0[ 0.904502] Oops: Oops: 0002 [#1] SMP NOPTI[ 0.904737] CPU: 0 UID: 0 PID: 135 Comm: exploit Not tainted 6.19.0-rc3+ #2 NONE[ 0.905157] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.17.0-0-gb52ca86e094d-prebuilt.qemu.org 04/01/2014[ 0.905754] RIP: 0010:qfq_deactivate_agg (include/linux/list.h:992 (discriminator 2) include/linux/list.h:1006 (discriminator 2) net/sched/sch_qfq.c:1367 (discriminator 2) net/sched/sch_qfq.c:1393 (discriminator 2))[ 0.906046] Code: 0f 84 4d 01 00 00 48 89 70 18 8b 4b 10 48 c7 c2 ff ff ff ff 48 8b 78 08 48 d3 e2 48 21 f2 48 2b 13 48 8b 30 48 d3 ea 8b 4b 18 0Code starting with the faulting instruction=========================================== 0: 0f 84 4d 01 00 00 je 0x153 6: 48 89 70 18 mov %rsi,0x18(%rax) a: 8b 4b 10 mov 0x10(%rbx),%ecx d: 48 c7 c2 ff ff ff ff mov $0xffffffffffffffff,%rdx 14: 48 8b 78 08 mov 0x8(%rax),%rdi 18: 48 d3 e2 shl %cl,%rdx 1b: 48 21 f2 and %rsi,%rdx 1e: 48 2b 13 sub (%rbx),%rdx 21: 48 8b 30 mov (%rax),%rsi 24: 48 d3 ea shr %cl,%rdx 27: 8b 4b 18 mov 0x18(%rbx),%ecx ...[ 0.907095] RSP: 0018:ffffc900004a39a0 EFLAGS: 00010246[ 0.907368] RAX: ffff8881043a0880 RBX: ffff888102953340 RCX: 0000000000000000[ 0.907723] RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000000[ 0.908100] RBP: ffff888102952180 R08: 0000000000000000 R09: 0000000000000000[ 0.908451] R10: ffff8881043a0000 R11: 0000000000000000 R12: ffff888102952000[ 0.908804] R13: ffff888102952180 R14: ffff8881043a0ad8 R15: ffff8881043a0880[ 0.909179] FS: 000000002a1a0380(0000) GS:ffff888196d8d000(0000) knlGS:0000000000000000[ 0.909572] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 0.909857] CR2: 0000000000000000 CR3: 0000000102993002 CR4: 0000000000772ef0[ 0.910247] PKRU: 55555554[ 0.910391] Call Trace:[ 0.910527] [ 0.910638] qfq_reset_qdisc (net/sched/sch_qfq.c:357 net/sched/sch_qfq.c:1485)[ 0.910826] qdisc_reset (include/linux/skbuff.h:2195 include/linux/skbuff.h:2501 include/linux/skbuff.h:3424 include/linux/skbuff.h:3430 net/sched/sch_generic.c:1036)[ 0.911040] __qdisc_destroy (net/sched/sch_generic.c:1076)[ 0.911236] tc_new_tfilter (net/sched/cls_api.c:2447)[ 0.911447] rtnetlink_rcv_msg (net/core/rtnetlink.c:6958)[ 0.911663] ? __pfx_rtnetlink_rcv_msg (net/core/rtnetlink.c:6861)[ 0.911894] netlink_rcv_skb (net/netlink/af_netlink.c:2550)[ 0.912100] netlink_unicast (net/netlink/af_netlink.c:1319 net/netlink/af_netlink.c:1344)[ 0.912296] ? __alloc_skb (net/core/skbuff.c:706)[ 0.912484] netlink_sendmsg (net/netlink/af---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:nvme-tcp: fix NULL pointer dereferences in nvmet_tcp_build_pdu_iovecCommit efa56305908b ("nvmet-tcp: Fix a kernel panic when host sends an invalid H2C PDU length")added ttag bounds checking and data_offsetvalidation in nvmet_tcp_handle_h2c_data_pdu(), but it did not validatewhether the command's data structures (cmd->req.sg and cmd->iov) havebeen properly initialized before processing H2C_DATA PDUs.The nvmet_tcp_build_pdu_iovec() function dereferences these pointerswithout NULL checks. This can be triggered by sending H2C_DATA PDUimmediately after the ICREQ/ICRESP handshake, beforesending a CONNECT command or NVMe write command.Attack vectors that trigger NULL pointer dereferences:1. H2C_DATA PDU sent before CONNECT -> both pointers NULL2. H2C_DATA PDU for READ command -> cmd->req.sg allocated, cmd->iov NULL3. H2C_DATA PDU for uninitialized command slot -> both pointers NULLThe fix validates both cmd->req.sg and cmd->iov before callingnvmet_tcp_build_pdu_iovec(). Both checks are required because:- Uninitialized commands: both NULL- READ commands: cmd->req.sg allocated, cmd->iov NULL- WRITE commands: both allocated

CVE-2026-23047 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:libceph: make calc_target() set t->paused, not just clear itCurrently calc_target() clears t->paused if the request shouldn't bepaused anymore, but doesn't ever set t->paused even though it's able todetermine when the request should be paused. Setting t->paused is leftto __submit_request() which is fine for regular requests but doesn'twork for linger requests -- since __submit_request() doesn't operateon linger requests, there is nowhere for lreq->t.paused to be set.One consequence of this is that watches don't get reestablished onpaused -> unpaused transitions in cases where requests have been pausedlong enough for the (paused) unwatch request to time out and for thesubsequent (re)watch request to enter the paused state. On top of thewatch not getting reestablished, rbd_reregister_watch() gets stuck withrbd_dev->watch_mutex held: rbd_register_watch __rbd_register_watch ceph_osdc_watch linger_reg_commit_waitIt's waiting for lreq->reg_commit_wait to be completed, but for that tohappen the respective request needs to end up on need_resend_linger listand be kicked when requests are unpaused. There is no chance for thatif the request in question is never marked paused in the first place.The fact that rbd_dev->watch_mutex remains taken out forever thenprevents the image from getting unmapped -- "rbd unmap" would inevitablyhang in D state on an attempt to grab the mutex.

When the devicereports a single receive queue, rndis_filter_device_add() does notallocate an indirection table, accepting RSS hash key updates in thisstate leads to a hang.Fix this by gating netvsc_set_rxfh() on ndc->rx_table_sz and return-EOPNOTSUPP when the table is absent.

Description: In the Linux kernel, the following vulnerability has been resolved:uacce: ensure safe queue release with state managementDirectly calling `put_queue` carries risks since it cannotguarantee that resources of `uacce_queue` have been fully releasedbeforehand. So adding a `stop_queue` operation for theUACCE_CMD_PUT_Q command and leaving the `put_queue` operation tothe final resource release ensures safety.Queue states are defined as follows:- UACCE_Q_ZOMBIE: Initial state- UACCE_Q_INIT: After opening `uacce`- UACCE_Q_STARTED: After `start` is issued via `ioctl`When executing `poweroff -f` in virt while accelerator are stillworking, `uacce_fops_release` and `uacce_remove` may executeconcurrently. This can cause `uacce_put_queue` within`uacce_fops_release` to access a NULL `ops` pointer. Therefore, addstate checks to prevent accessing freed pointers.

In the complete callbackesd_usb_read_bulk_callback(), the URBs are processed and resubmitted. Inesd_usb_close() the URBs are freed by callingusb_kill_anchored_urbs(&dev->rx_submitted).However, this does not take into account that the USB framework unanchorsthe URB before the complete function is called. This means that once anin-URB has been completed, it is no longer anchored and is ultimately notreleased in esd_usb_close().Fix the memory leak by anchoring the URB in theesd_usb_read_bulk_callback() to the dev->rx_submitted anchor.

Description: In the Linux kernel, the following vulnerability has been resolved:irqchip/gic-v3-its: Avoid truncating memory addressesOn 32-bit machines with CONFIG_ARM_LPAE, it is possible for lowmemallocations to be backed by addresses physical memory above the 32-bitaddress limit, as found while experimenting with larger VMSPLITconfigurations.This caused the qemu virt model to crash in the GICv3 driver, whichallocates the 'itt' object using GFP_KERNEL. Since all memory belowthe 4GB physical address limit is in ZONE_DMA in this configuration,kmalloc() defaults to higher addresses for ZONE_NORMAL, and theITS driver stores the physical address in a 32-bit 'unsigned long'variable.Change the itt_addr variable to the correct phys_addr_t type instead,along with all other variables in this driver that hold a physicaladdress.The gicv5 driver correctly uses u64 variables, while all other irqchipdrivers don't call virt_to_phys or similar interfaces. It's expected thatother device drivers have similar issues, but fixing this one issufficient for booting a virtio based guest.

Description: In the Linux kernel, the following vulnerability has been resolved:ipvlan: Make the addrs_lock be per portMake the addrs_lock be per port, not per ipvlan dev.Initial code seems to be written in the assumption,that any address change must occur under RTNL.But it is not so for the case of IPv6. So1) Introduce per-port addrs_lock.2) It was needed to fix places where it was forgottento take lock (ipvlan_open/ipvlan_close)This appears to be a very minor problem though.Since it's highly unlikely that ipvlan_add_addr() willbe called on 2 CPU simultaneously. But nevertheless,this could cause:1) False-negative of ipvlan_addr_busy(): one interfaceiterated through all port->ipvlans + ipvlan->addrsunder some ipvlan spinlock, and another added IPunder its own lock. Though this is only possiblefor IPv6, since looks like only ipvlan_addr6_event() can becalled without rtnl_lock.2) Race since ipvlan_ht_addr_add(port) is called underdifferent ipvlan->addrs_lock locksThis should not affect performance, since add/remove IPis a rare situation and spinlock is not taken on fastpaths.

CVE-2026-23113 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring/io-wq: check IO_WQ_BIT_EXIT inside work run loopCurrently this is checked before running the pending work. Normally thisis quite fine, as work items either end up blocking (which will create anew worker for other items), or they complete fairly quickly. But syzbotreports an issue where io-wq takes seemingly forever to exit, and with abit of debugging, this turns out to be because it queues a bunch of big(2GB - 4096b) reads with a /dev/msr* file. Since this file type doesn'tsupport ->read_iter(), loop_rw_iter() ends up handling them. Each readreturns 16MB of data read, which takes 20 (!!) seconds. With a bunch ofthese pending, processing the whole chain can take a long time. Easilylonger than the syzbot uninterruptible sleep timeout of 140 seconds.This then triggers a complaint off the io-wq exit path:INFO: task syz.4.135:6326 blocked for more than 143 seconds.

However, we can speed up the exit by checking theIO_WQ_BIT_EXIT inside the io_worker_handle_work() loop, as syzbot willexit the ring after queueing up all of these reads. Then once the firstitem is processed, io-wq will simply cancel the rest. That should avoidsyzbot running into this complaint again.

In this case, thecommand sequence is currently:- SCTP_CMD_PEER_INIT- SCTP_CMD_TIMER_STOP (T1_INIT)- SCTP_CMD_TIMER_START (T1_COOKIE)- SCTP_CMD_NEW_STATE (COOKIE_ECHOED)- SCTP_CMD_ASSOC_SHKEY- SCTP_CMD_GEN_COOKIE_ECHOIf SCTP_CMD_ASSOC_SHKEY fails, asoc->shkey remains NULL, whileasoc->peer.auth_capable and asoc->peer.peer_chunks have already been set bySCTP_CMD_PEER_INIT. This allows a DATA chunk with auth = 1 and shkey = NULLto be queued by sctp_datamsg_from_user().Since command interpretation stops on failure, no COOKIE_ECHO should beensent via SCTP_CMD_GEN_COOKIE_ECHO. However, the T1_COOKIE timer has alreadybeen started, and it may enqueue a COOKIE_ECHO into the outqueue later. Asa result, the DATA chunk can be transmitted together with the COOKIE_ECHOin sctp_outq_flush_data(), leading to the observed issue.Similar to the other places where it calls sctp_auth_asoc_init_active_key()right after sctp_process_init(), this patch moves the SCTP_CMD_ASSOC_SHKEYimmediately after SCTP_CMD_PEER_INIT, before stopping T1_INIT and startingT1_COOKIE. This ensures that if shared key generation fails, authenticatedDATA cannot be sent. It also allows the T1_INIT timer to retransmit INIT,giving the client another chance to process INIT_ACK and retry key setup.

Description: In the Linux kernel, the following vulnerability has been resolved:tracing: Add recursion protection in kernel stack trace recordingA bug was reported about an infinite recursion caused by tracing the rcuevents with the kernel stack trace trigger enabled. The stack trace codecalled back into RCU which then called the stack trace again.Expand the ftrace recursion protection to add a set of bits to protectevents from recursion. Each bit represents the context that the event isin (normal, softirq, interrupt and NMI).Have the stack trace code use the interrupt context to protect againstrecursion.Note, the bug showed an issue in both the RCU code as well as the tracingstacktrace code. This only handles the tracing stack trace side of thebug. The RCU fix will be handled separately.

CVE-2026-23154 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix segmentation of forwarding fraglist GROThis patch enhances GSO segment handling by properly checkingthe SKB_GSO_DODGY flag for frag_list GSO packets, addressinglow throughput issues observed when a station accesses IPv4servers via hotspots with an IPv6-only upstream interface.Specifically, it fixes a bug in GSO segmentation when forwardingGRO packets containing a frag_list. The function skb_segment_listcannot correctly process GRO skbs that have been converted by XLAT,since XLAT only translates the header of the head skb. Consequently,skbs in the frag_list may remain untranslated, resulting in protocolinconsistencies and reduced throughput.To address this, the patch explicitly sets the SKB_GSO_DODGY flagfor GSO packets in XLAT's IPv4/IPv6 protocol translation helpers(bpf_skb_proto_4_to_6 and bpf_skb_proto_6_to_4). This marks GSOpackets as potentially modified after protocol translation. As aresult, GSO segmentation will avoid using skb_segment_list andinstead falls back to skb_segment for packets with the SKB_GSO_DODGYflag. This ensures that only safe and fully translated frag_listpackets are processed by skb_segment_list, resolving protocolinconsistencies and improving throughput when forwarding GRO packetsconverted by XLAT.

CVE-2026-23157 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: do not strictly require dirty metadata threshold for metadata writepages[BUG]There is an internal report that over 1000 processes arewaiting at the io_schedule_timeout() of balance_dirty_pages(), causinga system hang and trigger a kernel coredump.The kernel is v6.4 kernel based, but the root problem still applies toany upstream kernel before v6.18.[CAUSE]From Jan Kara for his wisdom on the dirty page balance behavior first. This cgroup dirty limit was what was actually playing the role here because the cgroup had only a small amount of memory and so the dirty limit for it was something like 16MB. Dirty throttling is responsible for enforcing that nobody can dirty (significantly) more dirty memory than there's dirty limit. Thus when a task is dirtying pages it periodically enters into balance_dirty_pages() and we let it sleep there to slow down the dirtying. When the system is over dirty limit already (either globally or within a cgroup of the running task), we will not let the task exit from balance_dirty_pages() until the number of dirty pages drops below the limit. So in this particular case, as I already mentioned, there was a cgroup with relatively small amount of memory and as a result with dirty limit set at 16MB. A task from that cgroup has dirtied about 28MB worth of pages in btrfs btree inode and these were practically the only dirty pages in that cgroup.So that means the only way to reduce the dirty pages of that cgroup isto writeback the dirty pages of btrfs btree inode, and only after thatthose processes can exit balance_dirty_pages().Now back to the btrfs part, btree_writepages() is responsible forwriting back dirty btree inode pages.The problem here is, there is a btrfs internal threshold that if thebtree inode's dirty bytes are below the 32M threshold, it will notdo any writeback.This behavior is to batch as much metadata as possible so we won't writeback those tree blocks and then later re-COW them again for anothermodification.This internal 32MiB is higher than the existing dirty page size (28MiB),meaning no writeback will happen, causing a deadlock between btrfs andcgroup:- Btrfs doesn't want to write back btree inode until more dirty pages- Cgroup/MM doesn't want more dirty pages for btrfs btree inode Thus any process touching that btree inode is put into sleep until the number of dirty pages is reduced.Thanks Jan Kara a lot for the analysis of the root cause.[ENHANCEMENT]Since kernel commit b55102826d7d ("btrfs: set AS_KERNEL_FILE on thebtree_inode"), btrfs btree inode pages will only be charged to the rootcgroup which should have a much larger limit than btrfs' 32MiBthreshold.So it should not affect newer kernels.But for all current LTS kernels, they are all affected by this problem,and backporting the whole AS_KERNEL_FILE may not be a good idea.Even for newer kernels I still think it's a good idea to getrid of the internal threshold at btree_writepages(), since for most casescgroup/MM has a better view of full system memory usage than btrfs' fixedthreshold.For internal callers using btrfs_btree_balance_dirty() since thatfunction is already doing internal threshold check, we don't need tobother them.But for external callers of btree_writepages(), just respect theirrequests and write back whatever they want, ignoring the internalbtrfs threshold to avoid such deadlock on btree inode dirty pagebalancing.

Description: In the Linux kernel, the following vulnerability has been resolved:rocker: fix memory leak in rocker_world_port_post_fini()In rocker_world_port_pre_init(), rocker_port->wpriv is allocated withkzalloc(wops->port_priv_size, GFP_KERNEL). However, inrocker_world_port_post_fini(), the memory is only freed whenwops->port_post_fini callback is set: if (!wops->port_post_fini) return; wops->port_post_fini(rocker_port); kfree(rocker_port->wpriv);Since rocker_ofdpa_ops does not implement port_post_fini callback(it is NULL), the wpriv memory allocated for each port is never freedwhen ports are removed. This leads to a memory leak ofsizeof(struct ofdpa_port) bytes per port on every device removal.Fix this by always calling kfree(rocker_port->wpriv) regardless ofwhether the port_post_fini callback exists.

Description: In the Linux kernel, the following vulnerability has been resolved:nfc: nci: Fix race between rfkill and nci_unregister_device().syzbot reported the splat below [0] without a repro.It indicates that struct nci_dev.cmd_wq had been destroyed beforenci_close_device() was called via rfkill.nci_dev.cmd_wq is only destroyed in nci_unregister_device(), which(I think) was called from virtual_ncidev_close() when syzbot close()dan fd of virtual_ncidev.The problem is that nci_unregister_device() destroys nci_dev.cmd_wqfirst and then calls nfc_unregister_device(), which removes thedevice from rfkill by rfkill_unregister().So, the device is still visible via rfkill even after nci_dev.cmd_wqis destroyed.Let's unregister the device from rfkill first in nci_unregister_device().Note that we cannot call nfc_unregister_device() beforenci_close_device() because 1) nfc_unregister_device() calls device_del() which frees all memory allocated by devm_kzalloc() and linked to ndev->conn_info_list 2) nci_rx_work() could try to queue nci_conn_info to ndev->conn_info_list which could be leakedThus, nfc_unregister_device() is split into two functions so wecan remove rfkill interfaces only before nci_close_device().[0]:DEBUG_LOCKS_WARN_ON(1)WARNING: kernel/locking/lockdep.c:238 at hlock_class kernel/locking/lockdep.c:238 [inline], CPU#0: syz.0.8675/6349WARNING: kernel/locking/lockdep.c:238 at check_wait_context kernel/locking/lockdep.c:4854 [inline], CPU#0: syz.0.8675/6349WARNING: kernel/locking/lockdep.c:238 at __lock_acquire+0x39d/0x2cf0 kernel/locking/lockdep.c:5187, CPU#0: syz.0.8675/6349Modules linked in:CPU: 0 UID: 0 PID: 6349 Comm: syz.0.8675 Not tainted syzkaller #0 PREEMPT(full)Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/13/2026RIP: 0010:hlock_class kernel/locking/lockdep.c:238 [inline]RIP: 0010:check_wait_context kernel/locking/lockdep.c:4854 [inline]RIP: 0010:__lock_acquire+0x3a4/0x2cf0 kernel/locking/lockdep.c:5187Code: 18 00 4c 8b 74 24 08 75 27 90 e8 17 f2 fc 02 85 c0 74 1c 83 3d 50 e0 4e 0e 00 75 13 48 8d 3d 43 f7 51 0e 48 c7 c6 8b 3a de 8d <67> 48 0f b9 3a 90 31 c0 0f b6 98 c4 00 00 00 41 8b 45 20 25 ff 1fRSP: 0018:ffffc9000c767680 EFLAGS: 00010046RAX: 0000000000000001 RBX: 0000000000040000 RCX: 0000000000080000RDX: ffffc90013080000 RSI: ffffffff8dde3a8b RDI: ffffffff8ff24ca0RBP: 0000000000000003 R08: ffffffff8fef35a3 R09: 1ffffffff1fde6b4R10: dffffc0000000000 R11: fffffbfff1fde6b5 R12: 00000000000012a2R13: ffff888030338ba8 R14: ffff888030338000 R15: ffff888030338b30FS: 00007fa5995f66c0(0000) GS:ffff8881256f8000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007f7e72f842d0 CR3: 00000000485a0000 CR4: 00000000003526f0Call Trace: lock_acquire+0x106/0x330 kernel/locking/lockdep.c:5868 touch_wq_lockdep_map+0xcb/0x180 kernel/workqueue.c:3940 __flush_workqueue+0x14b/0x14f0 kernel/workqueue.c:3982 nci_close_device+0x302/0x630 net/nfc/nci/core.c:567 nci_dev_down+0x3b/0x50 net/nfc/nci/core.c:639 nfc_dev_down+0x152/0x290 net/nfc/core.c:161 nfc_rfkill_set_block+0x2d/0x100 net/nfc/core.c:179 rfkill_set_block+0x1d2/0x440 net/rfkill/core.c:346 rfkill_fop_write+0x461/0x5a0 net/rfkill/core.c:1301 vfs_write+0x29a/0xb90 fs/read_write.c:684 ksys_write+0x150/0x270 fs/read_write.c:738 do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline] do_syscall_64+0xe2/0xf80 arch/x86/entry/syscall_64.c:94 entry_SYSCALL_64_after_hwframe+0x77/0x7fRIP: 0033:0x7fa59b39acb9Code: ff c3 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 e8 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007fa5995f6028 EFLAGS: 00000246 ORIG_RAX: 0000000000000001RAX: ffffffffffffffda RBX: 00007fa59b615fa0 RCX: 00007fa59b39acb9RDX: 0000000000000008 RSI: 0000200000000080 RDI: 0000000000000007RBP: 00007fa59b408bf7 R08: ---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:platform/x86: classmate-laptop: Add missing NULL pointer checksIn a few places in the Classmate laptop driver, code using the accelobject may run before that object's address is stored in the driverdata of the input device using it.For example, cmpc_accel_sensitivity_store_v4() is the "show" methodof cmpc_accel_sensitivity_attr_v4 which is added in cmpc_accel_add_v4(),before calling dev_set_drvdata() for inputdev->dev. If the sysfsattribute is accessed prematurely, the dev_get_drvdata(&inputdev->dev)call in in cmpc_accel_sensitivity_store_v4() returns NULL whichleads to a NULL pointer dereference going forward.Moreover, sysfs attributes using the input device are added beforeinitializing that device by cmpc_add_acpi_notify_device() and if oneof them is accessed before running that function, a NULL pointerdereference will occur.For example, cmpc_accel_sensitivity_attr_v4 is added before callingcmpc_add_acpi_notify_device() and if it is read prematurely, thedev_get_drvdata(&acpi->dev) call in cmpc_accel_sensitivity_show_v4()returns NULL which leads to a NULL pointer dereference going forward.Fix this by adding NULL pointer checks in all of the relevant places.

Description: In the Linux kernel, the following vulnerability has been resolved:media: dvb-core: fix wrong reinitialization of ringbuffer on reopendvb_dvr_open() calls dvb_ringbuffer_init() when a new reader opens theDVR device. dvb_ringbuffer_init() calls init_waitqueue_head(), whichreinitializes the waitqueue list head to empty.Since dmxdev->dvr_buffer.queue is a shared waitqueue (all opens of thesame DVR device share it), this orphans any existing waitqueue entriesfrom io_uring poll or epoll, leaving them with stale prev/next pointerswhile the list head is reset to {self, self}.The waitqueue and spinlock in dvr_buffer are already properlyinitialized once in dvb_dmxdev_init(). The open path only needs toreset the buffer data pointer, size, and read/write positions.Replace the dvb_ringbuffer_init() call in dvb_dvr_open() with directassignment of data/size and a call to dvb_ringbuffer_reset(), whichproperly resets pread, pwrite, and error with correct memory orderingwithout touching the waitqueue or spinlock.

CVE-2026-23287 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:irqchip/sifive-plic: Fix frozen interrupt due to affinity settingPLIC ignores interrupt completion message for disabled interrupt, explainedby the specification: The PLIC signals it has completed executing an interrupt handler by writing the interrupt ID it received from the claim to the claim/complete register. The PLIC does not check whether the completion ID is the same as the last claim ID for that target. If the completion ID does not match an interrupt source that is currently enabled for the target, the completion is silently ignored.This caused problems in the past, because an interrupt can be disabledwhile still being handled and plic_irq_eoi() had no effect. That was fixedby checking if the interrupt is disabled, and if so enable it, beforesending the completion message. That check is done with irqd_irq_disabled().However, that is not sufficient because the enable bit for the handlinghart can be zero despite irqd_irq_disabled(d) being false. This can happenwhen affinity setting is changed while a hart is still handling theinterrupt.This problem is easily reproducible by dumping a large file to uart (whichgenerates lots of interrupts) and at the same time keep changing the uartinterrupt's affinity setting. The uart port becomes frozen almostinstantaneously.Fix this by checking PLIC's enable bit instead of irqd_irq_disabled().

Description: In the Linux kernel, the following vulnerability has been resolved:x86/efi: defer freeing of boot services memoryefi_free_boot_services() frees memory occupied by EFI_BOOT_SERVICES_CODEand EFI_BOOT_SERVICES_DATA using memblock_free_late().There are two issue with that: memblock_free_late() should be used formemory allocated with memblock_alloc() while the memory reserved withmemblock_reserve() should be freed with free_reserved_area().More acutely, with CONFIG_DEFERRED_STRUCT_PAGE_INIT=yefi_free_boot_services() is called before deferred initialization of thememory map is complete.Benjamin Herrenschmidt reports that this causes a leak of ~140MB ofRAM on EC2 t3a.nano instances which only have 512MB or RAM.If the freed memory resides in the areas that memory map for them isstill uninitialized, they won't be actually freed becausememblock_free_late() calls memblock_free_pages() and the latter skipsuninitialized pages.Using free_reserved_area() at this point is also problematic because__free_page() accesses the buddy of the freed page and that again mightend up in uninitialized part of the memory map.Delaying the entire efi_free_boot_services() could be problematicbecause in addition to freeing boot services memory it updatesefi.memmap without any synchronization and that's undesirable late inboot when there is concurrency.More robust approach is to only defer freeing of the EFI boot servicesmemory.Split efi_free_boot_services() in two. First efi_unmap_boot_services()collects ranges that should be freed into an array thenefi_free_boot_services() later frees them after deferred init is complete.

Description: In the Linux kernel, the following vulnerability has been resolved:nfc: rawsock: cancel tx_work before socket teardownIn rawsock_release(), cancel any pending tx_work and purge the writequeue before orphaning the socket. rawsock_tx_work runs on the systemworkqueue and calls nfc_data_exchange which dereferences the NCIdevice. Without synchronization, tx_work can race with socket anddevice teardown when a process is killed (e.g. by SIGKILL), leadingto use-after-free or leaked references.Set SEND_SHUTDOWN first so that if tx_work is already running it willsee the flag and skip transmitting, then use cancel_work_sync to waitfor any in-progress execution to finish, and finally purge anyremaining queued skbs.

It iterates num_bufs times and attempts to unmapentries in the dma array.This leads to two issues:1. The dma array shares storage with tx_qpl_buf_ids (union). Interpreting buffer IDs as DMA addresses results in attempting to unmap incorrect memory locations.2. num_bufs in QPL mode (counting 2K chunks) can significantly exceed the size of the dma array, causing out-of-bounds access warnings(trace below is how we noticed this issue).UBSAN: array-index-out-of-bounds indrivers/net/ethernet/drivers/net/ethernet/google/gve/gve_tx_dqo.c:178:5 index 18 is out ofrange for type 'dma_addr_t[18]' (aka 'unsigned long long[18]')Workqueue: gve gve_service_task [gve]Call Trace:dump_stack_lvl+0x33/0xa0__ubsan_handle_out_of_bounds+0xdc/0x110gve_tx_stop_ring_dqo+0x182/0x200 [gve]gve_close+0x1be/0x450 [gve]gve_reset+0x99/0x120 [gve]gve_service_task+0x61/0x100 [gve]process_scheduled_works+0x1e9/0x380Fix this by properly checking for QPL mode and delegating togve_free_tx_qpl_bufs() to reclaim the buffers.

Callers such asfou_create() then proceed to dereference the uninitialized socketpointer, resulting in a NULL pointer dereference.The captured NULL deref crash: BUG: kernel NULL pointer dereference, address: 0000000000000018 RIP: 0010:fou_nl_add_doit (net/ipv4/fou_core.c:590 net/ipv4/fou_core.c:764) [...] Call Trace: genl_family_rcv_msg_doit.constprop.0 (net/netlink/genetlink.c:1114) genl_rcv_msg (net/netlink/genetlink.c:1194 net/netlink/genetlink.c:1209) [...] netlink_rcv_skb (net/netlink/af_netlink.c:2550) genl_rcv (net/netlink/genetlink.c:1219) netlink_unicast (net/netlink/af_netlink.c:1319 net/netlink/af_netlink.c:1344) netlink_sendmsg (net/netlink/af_netlink.c:1894) __sock_sendmsg (net/socket.c:727 (discriminator 1) net/socket.c:742 (discriminator 1)) __sys_sendto (./include/linux/file.h:62 (discriminator 1) ./include/linux/file.h:83 (discriminator 1) net/socket.c:2183 (discriminator 1)) __x64_sys_sendto (net/socket.c:2213 (discriminator 1) net/socket.c:2209 (discriminator 1) net/socket.c:2209 (discriminator 1)) do_syscall_64 (arch/x86/entry/syscall_64.c:63 (discriminator 1) arch/x86/entry/syscall_64.c:94 (discriminator 1)) entry_SYSCALL_64_after_hwframe (net/arch/x86/entry/entry_64.S:130)This patch makes udp_sock_create6 return -EPFNOSUPPORT instead, socallers correctly take their error paths.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amdgpu: Limit BO list entry count to prevent resource exhaustionUserspace can pass an arbitrary number of BO list entries via thebo_number field. Although the previous multiplication overflow checkprevents out-of-bounds allocation, a large number of entries could stillcause excessive memory allocation (up to potentially gigabytes) andunnecessarily long list processing times.Introduce a hard limit of 128k entries per BO list, which is more thansufficient for any realistic use case (e.g., a single list containing allbuffers in a large scene). This prevents memory exhaustion attacks andensures predictable performance.Return -EINVAL if the requested entry count exceeds the limit(cherry picked from commit 688b87d39e0aa8135105b40dc167d74b5ada5332)

CVE-2026-25645 Severity: Moderate CVSS3 score: 5.5

Description: Requests is a HTTP library. Prior to version 2.33.0, the `requests.utils.extract_zipped_paths()` utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validation. A local attacker with write access to the temp directory could pre-create a malicious file that would be loaded in place of the legitimate one. Standard usage of the Requests library is not affected by this vulnerability. Only applications that call `extract_zipped_paths()` directly are impacted. Starting in version 2.33.0, the library extracts files to a non-deterministic location. If developers are unable to upgrade, they can set `TMPDIR` in their environment to a directory with restricted write access.

CVE-2026-29111 Severity: Moderate CVSS3 score: 5.5

Description: systemd, a system and service manager, (as PID 1) hits an assert and freezes execution when an unprivileged IPC API call is made with spurious data. On version v249 and older the effect is not an assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is not possible as the safety check causes an assert instead. This IPC call was added in v239, so versions older than that are not affected. Versions 260-rc1, 259.2, 258.5, and 257.11 contain patches. No known workarounds are available.

CVE-2026-31411 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: atm: fix crash due to unvalidated vcc pointer in sigd_send()Reproducer available at [1].The ATM send path (sendmsg -> vcc_sendmsg -> sigd_send) reads the vccpointer from msg->vcc and uses it directly without any validation. Thispointer comes from userspace via sendmsg() and can be arbitrarily forged: int fd = socket(AF_ATMSVC, SOCK_DGRAM, 0); ioctl(fd, ATMSIGD_CTRL); // become ATM signaling daemon struct msghdr msg = { .msg_iov = &iov, ... }; *(unsigned long *)(buf + 4) = 0xdeadbeef; // fake vcc pointer sendmsg(fd, &msg, 0); // kernel dereferences 0xdeadbeefIn normal operation, the kernel sends the vcc pointer to the signalingdaemon via sigd_enq() when processing operations like connect(), bind(),or listen(). The daemon is expected to return the same pointer whenresponding. However, a malicious daemon can send arbitrary pointer values.Fix this by introducing find_get_vcc() which validates the pointer bysearching through vcc_hash (similar to how sigd_close() iterates overall VCCs), and acquires a reference via sock_hold() if found.Since struct atm_vcc embeds struct sock as its first member, they sharethe same lifetime. Therefore using sock_hold/sock_put is sufficient tokeep the vcc alive while it is being used.Note that there may be a race with sigd_close() which could mark the vccwith various flags (e.g., ATM_VF_RELEASED) after find_get_vcc() returns.However, sock_hold() guarantees the memory remains valid, so this raceonly affects the logical state, not memory safety.[1]: https://gist.github.com/mrpre/1ba5949c45529c511152e2f4c755b0f3

Description: In the Linux kernel, the following vulnerability has been resolved:bridge: mrp: reject zero test interval to avoid OOM panicbr_mrp_start_test() and br_mrp_start_in_test() accept the user-suppliedinterval value from netlink without validation. When interval is 0,usecs_to_jiffies(0) yields 0, causing the delayed work(br_mrp_test_work_expired / br_mrp_in_test_work_expired) to rescheduleitself with zero delay. This creates a tight loop on system_percpu_wqthat allocates and transmits MRP test frames at maximum rate, exhaustingall system memory and causing a kernel panic via OOM deadlock.The same zero-interval issue applies to br_mrp_start_in_test_parse()for interconnect test frames.Use NLA_POLICY_MIN(NLA_U32, 1) in the nla_policy tables for bothIFLA_BRIDGE_MRP_START_TEST_INTERVAL andIFLA_BRIDGE_MRP_START_IN_TEST_INTERVAL, so zero is rejected at thenetlink attribute parsing layer before the value ever reaches theworkqueue scheduling code. This is consistent with how other bridgesubsystems (br_fdb, br_mst) enforce range constraints on netlinkattributes.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: x_tables: restrict xt_check_match/xt_check_target extensions for NFPROTO_ARPWeiming Shi says:xt_match and xt_target structs registered with NFPROTO_UNSPEC can beloaded by any protocol family through nft_compat. When such amatch/target sets .hooks to restrict which hooks it may run on, thebitmask uses NF_INET_* constants. This is only correct for familieswhose hook layout matches NF_INET_*: IPv4, IPv6, INET, and bridgeall share the same five hooks (PRE_ROUTING ... POST_ROUTING).ARP only has three hooks (IN=0, OUT=1, FORWARD=2) with differentsemantics. Because NF_ARP_OUT == 1 == NF_INET_LOCAL_IN, the .hooksvalidation silently passes for the wrong reasons, allowing matches torun on ARP chains where the hook assumptions (e.g. state->in beingset on input hooks) do not hold.

CVE-2026-31425 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:rds: ib: reject FRMR registration before IB connection is establishedrds_ib_get_mr() extracts the rds_ib_connection from conn->c_transport_dataand passes it to rds_ib_reg_frmr() for FRWR memory registration. On afresh outgoing connection, ic is allocated in rds_ib_conn_alloc() withi_cm_id = NULL because the connection worker has not yet calledrds_ib_conn_path_connect() to create the rdma_cm_id.

Description: In the Linux kernel, the following vulnerability has been resolved:xfs: avoid dereferencing log items after push callbacksAfter xfsaild_push_item() calls iop_push(), the log item may have beenfreed if the AIL lock was dropped during the push. Background inodereclaim or the dquot shrinker can free the log item while the AIL lockis not held, and the tracepoints in the switch statement dereferencethe log item after iop_push() returns.Fix this by capturing the log item type, flags, and LSN before callingxfsaild_push_item(), and introducing a new xfs_ail_push_class traceevent class that takes these pre-captured values and the ailp pointerinstead of the log item pointer.

Description: In the Linux kernel, the following vulnerability has been resolved:xfs: save ailp before dropping the AIL lock in push callbacksIn xfs_inode_item_push() and xfs_qm_dquot_logitem_push(), the AIL lockis dropped to perform buffer IO. Once the cluster buffer no longerprotects the log item from reclaim, the log item may be freed bybackground reclaim or the dquot shrinker. The subsequent spin_lock()call dereferences lip->li_ailp, which is a use-after-free.Fix this by saving the ailp pointer in a local variable while the AILlock is held and the log item is guaranteed to be valid.

This is brokenindependently of any use-after-free issues - background reclaim andinodegc should not be running while the AIL is being pushed duringunmount, as inodegc can dirty and insert inodes into the AIL during theflush, and background reclaim can race to abort and free dirty inodes.Reorder xfs_unmount_flush_inodes() to stop inodegc and cancel backgroundreclaim before pushing the AIL.

Description: Tornado is a Python web framework and asynchronous networking library. In versions 6.5.2 and below, the supplied reason phrase is used unescaped in HTTP headers (where it could be used for header injection) or in HTML in the default error page (where it could be used for XSS) and can be exploited by passing untrusted or malicious data into the reason argument. Used by both RequestHandler.set_status and tornado.web.HTTPError, the argument is designed to allow applications to pass custom "reason" phrases (the "Not Found" in HTTP/1.1 404 Not Found) to the HTTP status line (mainly for non-standard status codes). This issue is fixed in version 6.5.3.

Description: Vim is an open source, command line text editor. Prior to 9.1.2148, a stack buffer overflow vulnerability exists in Vim's NetBeans integration when processing the specialKeys command, affecting Vim builds that enable and use the NetBeans feature. The Stack buffer overflow exists in special_keys() (in src/netbeans.c). The while (*tok) loop writes two bytes per iteration into a 64-byte stack buffer (keybuf) with no bounds check. A malicious NetBeans server can overflow keybuf with a single specialKeys command. The issue has been fixed as of Vim patch v9.1.2148.

CVE-2022-48910 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:net: ipv6: ensure we call ipv6_mc_down() at most onceThere are two reasons for addrconf_notify() to be called with NETDEV_DOWN:either the network device is actually going down, or IPv6 was disabledon the interface.If either of them stays down while the other is toggled, we repeatedlycall the code for NETDEV_DOWN, including ipv6_mc_down(), while nevercalling the corresponding ipv6_mc_up() in between. This will cause anew entry in idev->mc_tomb to be allocated for each multicast groupthe interface is subscribed to, which in turn leaks one struct ifmcaddr6per nontrivial multicast group the interface is subscribed to.The following reproducer will leak at least $n objects:ip addr add ff2e::4242/32 dev eth0 autojoinsysctl -w net.ipv6.conf.eth0.disable_ipv6=1for i in $(seq 1 $n); do ip link set up eth0; ip link set down eth0doneJoining groups with IPV6_ADD_MEMBERSHIP (unprivileged) or setting thesysctl net.ipv6.conf.eth0.forwarding to 1 (=> subscribing to ff02::2)can also be used to create a nontrivial idev->mc_list, which will theleak objects with the right up-down-sequence.Based on both sources for NETDEV_DOWN events the interface IPv6 stateshould be considered: - not ready if the network interface is not ready OR IPv6 is disabled for it - ready if the network interface is ready AND IPv6 is enabled for itThe functions ipv6_mc_up() and ipv6_down() should only be run when thisstate changes.Implement this by remembering when the IPv6 state is ready, and onlyrun ipv6_mc_down() if it actually changed from ready to not ready.The other direction (not ready -> ready) already works correctly, as: - the interface notification triggered codepath for NETDEV_UP / NETDEV_CHANGE returns early if ipv6 is disabled, and - the disable_ipv6=0 triggered codepath skips fully initializing the interface as long as addrconf_link_ready(dev) returns false - calling ipv6_mc_up() repeatedly does not leak anything

Description: In the Linux kernel, the following vulnerability has been resolved:blk-mq: avoid double ->queue_rq() because of early timeoutDavid Jeffery found one double ->queue_rq() issue, so far it canbe triggered in VM use case because of long vmexit latency or preemptlatency of vCPU pthread or long page fault in vCPU pthread, then blockIO req could be timed out before queuing the request to hardware but aftercalling blk_mq_start_request() during ->queue_rq(), then timeout handlermay handle it by requeue, then double ->queue_rq() is caused, and kernelpanic.So far, it is driver's responsibility to cover the race between timeoutand completion, so it seems supposed to be solved in driver in theory,given driver has enough knowledge.But it is really one common problem, lots of driver could have similarissue, and could be hard to fix all affected drivers, even it isn't easyfor driver to handle the race. So David suggests this patch by drainingin-progress ->queue_rq() for solving this issue.

CVE-2023-53728 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:posix-timers: Ensure timer ID search-loop limit is validposix_timer_add() tries to allocate a posix timer ID by starting from thecached ID which was stored by the last successful allocation.This is done in a loop searching the ID space for a free slot one byone. The loop has to terminate when the search wrapped around to thestarting point.But that's racy vs. establishing the starting point. That is read outlockless, which leads to the following problem:CPU0 CPU1posix_timer_add() start = sig->posix_timer_id; lock(hash_lock); ... posix_timer_add() if (++sig->posix_timer_id < 0) start = sig->posix_timer_id; sig->posix_timer_id = 0;So CPU1 can observe a negative start value, i.e. -1, and the loop breaknever happens because the condition can never be true: if (sig->posix_timer_id == start) break;While this is unlikely to ever turn into an endless loop as the ID space ishuge (INT_MAX), the racy read of the start value caught the attention ofKCSAN and Dmitry unearthed that incorrectness.Rewrite it so that all id operations are under the hash lock.

Description: In the Linux kernel, the following vulnerability has been resolved:dccp: Fix out of bounds access in DCCP error handlerThere was a previous attempt to fix an out-of-bounds access in the DCCPerror handlers, but that fix assumed that the error handlers only wantto access the first 8 bytes of the DCCP header. Actually, they also lookat the DCCP sequence number, which is stored beyond 8 bytes, so anexplicit pskb_may_pull() is required.

CVE-2023-53845 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: fix infinite loop in nilfs_mdt_get_block()If the disk image that nilfs2 mounts is corrupted and a virtual blockaddress obtained by block lookup for a metadata file is invalid,nilfs_bmap_lookup_at_level() may return the same internal return code as-ENOENT, meaning the block does not exist in the metadata file.This duplication of return codes confuses nilfs_mdt_get_block(), causingit to read and create a metadata block indefinitely.In particular, if this happens to the inode metadata file, ifile,semaphore i_rwsem can be left held, causing task hangs in lock_mount.Fix this issue by making nilfs_bmap_lookup_at_level() treat virtual blockaddress translation failures with -ENOENT as metadata corruption insteadof returning the error code.

CVE-2024-36933 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:nsh: Restore skb->{protocol,data,mac_header} for outer header in nsh_gso_segment().syzbot triggered various splats (see [0] and links) by a crafted GSOpacket of VIRTIO_NET_HDR_GSO_UDP layering the following protocols: ETH_P_8021AD + ETH_P_NSH + ETH_P_IPV6 + IPPROTO_UDPNSH can encapsulate IPv4, IPv6, Ethernet, NSH, and MPLS. As the innerprotocol can be Ethernet, NSH GSO handler, nsh_gso_segment(), callsskb_mac_gso_segment() to invoke inner protocol GSO handlers.nsh_gso_segment() does the following for the original skb beforecalling skb_mac_gso_segment() 1. reset skb->network_header 2. save the original skb->{mac_heaeder,mac_len} in a local variable 3. pull the NSH header 4. resets skb->mac_header 5. set up skb->mac_len and skb->protocol for the inner protocol.and does the following for the segmented skb 6. set ntohs(ETH_P_NSH) to skb->protocol 7. push the NSH header 8. restore skb->mac_header 9. set skb->mac_header + mac_len to skb->network_header 10. restore skb->mac_lenThere are two problems in 6-7 and 8-9. (a) After 6 & 7, skb->data points to the NSH header, so the outer header (ETH_P_8021AD in this case) is stripped when skb is sent out of netdev. Also, if NSH is encapsulated by NSH + Ethernet (so NSH-Ethernet-NSH), skb_pull() in the first nsh_gso_segment() will make skb->data point to the middle of the outer NSH or Ethernet header because the Ethernet header is not pulled by the second nsh_gso_segment(). (b) While restoring skb->{mac_header,network_header} in 8 & 9, nsh_gso_segment() does not assume that the data in the linear buffer is shifted. However, udp6_ufo_fragment() could shift the data and change skb->mac_header accordingly as demonstrated by syzbot. If this happens, even the restored skb->mac_header points to the middle of the outer header.It seems nsh_gso_segment() has never worked with outer headers so far.At the end of nsh_gso_segment(), the outer header must be restored forthe segmented skb, instead of the NSH header.To do that, let's calculate the outer header position relatively fromthe inner header and set skb->{data,mac_header,protocol} properly.[0]:BUG: KMSAN: uninit-value in ipvlan_process_outbound drivers/net/ipvlan/ipvlan_core.c:524 [inline]BUG: KMSAN: uninit-value in ipvlan_xmit_mode_l3 drivers/net/ipvlan/ipvlan_core.c:602 [inline]BUG: KMSAN: uninit-value in ipvlan_queue_xmit+0xf44/0x16b0 drivers/net/ipvlan/ipvlan_core.c:668 ipvlan_process_outbound drivers/net/ipvlan/ipvlan_core.c:524 [inline] ipvlan_xmit_mode_l3 drivers/net/ipvlan/ipvlan_core.c:602 [inline] ipvlan_queue_xmit+0xf44/0x16b0 drivers/net/ipvlan/ipvlan_core.c:668 ipvlan_start_xmit+0x5c/0x1a0 drivers/net/ipvlan/ipvlan_main.c:222 __netdev_start_xmit include/linux/netdevice.h:4989 [inline] netdev_start_xmit include/linux/netdevice.h:5003 [inline] xmit_one net/core/dev.c:3547 [inline] dev_hard_start_xmit+0x244/0xa10 net/core/dev.c:3563 __dev_queue_xmit+0x33ed/0x51c0 net/core/dev.c:4351 dev_queue_xmit include/linux/netdevice.h:3171 [inline] packet_xmit+0x9c/0x6b0 net/packet/af_packet.c:276 packet_snd net/packet/af_packet.c:3081 [inline] packet_sendmsg+0x8aef/0x9f10 net/packet/af_packet.c:3113 sock_sendmsg_nosec net/socket.c:730 [inline] __sock_sendmsg net/socket.c:745 [inline] __sys_sendto+0x735/0xa10 net/socket.c:2191 __do_sys_sendto net/socket.c:2203 [inline] __se_sys_sendto net/socket.c:2199 [inline] __x64_sys_sendto+0x125/0x1c0 net/socket.c:2199 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xcf/0x1e0 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x63/0x6bUninit was created at: slab_post_alloc_hook mm/slub.c:3819 [inline] slab_alloc_node mm/slub.c:3860 [inline] __do_kmalloc_node mm/slub.c:3980 [inline] __kmalloc_node_track_caller+0x705/0x1000 mm/slub.c:4001 kmalloc_reserve+0x249/0x4a0 net/core/skbuff.c:582 __---truncated---

CVE-2025-22058 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:udp: Fix memory accounting leak.Matt Dowling reported a weird UDP memory usage issue.Under normal operation, the UDP memory usage reported in /proc/net/sockstatremains close to zero. However, it occasionally spiked to 524,288 pagesand never dropped. Moreover, the value doubled when the application wasterminated. Finally, it caused intermittent packet drops.We can reproduce the issue with the script below [0]: 1. /proc/net/sockstat reports 0 pages # cat /proc/net/sockstat | grep UDP: UDP: inuse 1 mem 0 2. Run the script till the report reaches 524,288 # python3 test.py & sleep 5 # cat /proc/net/sockstat | grep UDP: UDP: inuse 3 mem 524288 <-- (INT_MAX + 1) >> PAGE_SHIFT 3. Kill the socket and confirm the number never drops # pkill python3 && sleep 5 # cat /proc/net/sockstat | grep UDP: UDP: inuse 1 mem 524288 4. (necessary since v6.0) Trigger proto_memory_pcpu_drain() # python3 test.py & sleep 1 && pkill python3 5. The number doubles # cat /proc/net/sockstat | grep UDP: UDP: inuse 1 mem 1048577The application set INT_MAX to SO_RCVBUF, which triggered an integeroverflow in udp_rmem_release().When a socket is close()d, udp_destruct_common() purges its receivequeue and sums up skb->truesize in the queue. This total is calculatedand stored in a local unsigned integer variable.The total size is then passed to udp_rmem_release() to adjust memoryaccounting. However, because the function takes a signed integerargument, the total size can wrap around, causing an overflow.Then, the released amount is calculated as follows: 1) Add size to sk->sk_forward_alloc. 2) Round down sk->sk_forward_alloc to the nearest lower multiple of PAGE_SIZE and assign it to amount. 3) Subtract amount from sk->sk_forward_alloc. 4) Pass amount >> PAGE_SHIFT to __sk_mem_reduce_allocated().When the issue occurred, the total in udp_destruct_common() was 2147484480(INT_MAX + 833), which was cast to -2147482816 in udp_rmem_release().At 1) sk->sk_forward_alloc is changed from 3264 to -2147479552, and2) sets -2147479552 to amount. 3) reverts the wraparound, so we don'tsee a warning in inet_sock_destruct(). However, udp_memory_allocatedends up doubling at 4).Since commit 3cd3399dd7a8 ("net: implement per-cpu reserves formemory_allocated"), memory usage no longer doubles immediately aftera socket is close()d because __sk_mem_reduce_allocated() caches theamount in udp_memory_per_cpu_fw_alloc. However, the next time a UDPsocket receives a packet, the subtraction takes effect, causing UDPmemory usage to double.This issue makes further memory allocation fail once the socket'ssk->sk_rmem_alloc exceeds net.ipv4.udp_rmem_min, resulting in packetdrops.To prevent this issue, let's use unsigned int for the calculation andcall sk_forward_alloc_add() only once for the small delta.Note that first_packet_length() also potentially has the same problem.[0]:from socket import *SO_RCVBUFFORCE = 33INT_MAX = (2 ** 31) - 1s = socket(AF_INET, SOCK_DGRAM)s.bind(('', 0))s.setsockopt(SOL_SOCKET, SO_RCVBUFFORCE, INT_MAX)c = socket(AF_INET, SOCK_DGRAM)c.connect(s.getsockname())data = b'a' * 100while True: c.send(data)

CVE-2025-38097 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:espintcp: remove encap socket caching to avoid reference leakThe current scheme for caching the encap socket can lead to referenceleaks when we try to delete the netns.The reference chain is: xfrm_state -> enacp_sk -> netnsSince the encap socket is a userspace socket, it holds a reference onthe netns. If we delete the espintcp state (through flush orindividual delete) before removing the netns, the reference on thesocket is dropped and the netns is correctly deleted. Otherwise, thenetns may not be reachable anymore (if all processes within the nshave terminated), so we cannot delete the xfrm state to drop itsreference on the socket.This patch results in a small (~2% in my tests) performanceregression.A GC-type mechanism could be added for the socket cache, to clearreferences if the state hasn't been used "recently", but it's a lotmore complex than just not caching the socket.

CVE-2025-38478 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: Fix initialization of data for instructions that write to subdeviceSome Comedi subdevice instruction handlers are known to accessinstruction data elements beyond the first `insn->n` elements in somecases. The `do_insn_ioctl()` and `do_insnlist_ioctl()` functionsallocate at least `MIN_SAMPLES` (16) data elements to deal with this,but they do not initialize all of that. For Comedi instruction codesthat write to the subdevice, the first `insn->n` data elements arecopied from user-space, but the remaining elements are leftuninitialized. That could be a problem if the subdevice instructionhandler reads the uninitialized data. Ensure that the first`MIN_SAMPLES` elements are initialized before calling these instructionhandlers, filling the uncopied elements with 0. For`do_insnlist_ioctl()`, the same data buffer elements are used forhandling a list of instructions, so ensure the first `MIN_SAMPLES`elements are initialized for each instruction that writes to thesubdevice.

CVE-2025-38480 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: Fix use of uninitialized data in insn_rw_emulate_bits()For Comedi `INSN_READ` and `INSN_WRITE` instructions on "digital"subdevices (subdevice types `COMEDI_SUBD_DI`, `COMEDI_SUBD_DO`, and`COMEDI_SUBD_DIO`), it is common for the subdevice driver not to have`insn_read` and `insn_write` handler functions, but to have an`insn_bits` handler function for handling Comedi `INSN_BITS`instructions. In that case, the subdevice's `insn_read` and/or`insn_write` function handler pointers are set to point to the`insn_rw_emulate_bits()` function by `__comedi_device_postconfig()`.For `INSN_WRITE`, `insn_rw_emulate_bits()` currently assumes that thesupplied `data[0]` value is a valid copy from user memory. It will atleast exist because `do_insnlist_ioctl()` and `do_insn_ioctl()` in"comedi_fops.c" ensure at lease `MIN_SAMPLES` (16) elements areallocated. However, if `insn->n` is 0 (which is allowable for`INSN_READ` and `INSN_WRITE` instructions, then `data[0]` may containuninitialized data, and certainly contains invalid data, possibly from adifferent instruction in the array of instructions handled by`do_insnlist_ioctl()`. This will result in an incorrect value beingwritten to the digital output channel (or to the digital input/outputchannel if configured as an output), and may be reflected in theinternal saved state of the channel.Fix it by returning 0 early if `insn->n` is 0, before reaching the codethat accesses `data[0]`. Previously, the function always returned 1 onsuccess, but it is supposed to be the number of data samples actuallyread or written up to `insn->n`, which is 0 in this case.

However, cifs_oplock_break() continues to access thecinode after this point, resulting in use-after-free.Fix this by holding an extra reference to the superblock during theentire oplock break operation. This ensures that the superblock andits inodes remain valid until the oplock break completes.

Description: In the Linux kernel, the following vulnerability has been resolved:ceph: fix race condition validating r_parent before applying stateAdd validation to ensure the cached parent directory inode matches thedirectory info in MDS replies. This prevents client-side race conditionswhere concurrent operations (e.g. rename) cause r_parent to become stalebetween request initiation and reply processing, which could lead toapplying state changes to incorrect directory inodes.[ idryomov: folded a kerneldoc fixup and a follow-up fix from Alex to move CEPH_CAP_PIN reference when r_parent is updated: When the parent directory lock is not held, req->r_parent can become stale and is updated to point to the correct inode. However, the associated CEPH_CAP_PIN reference was not being adjusted. The CEPH_CAP_PIN is a reference on an inode that is tracked for accounting purposes. Moving this pin is important to keep the accounting balanced. When the pin was not moved from the old parent to the new one, it created two problems: The reference on the old, stale parent was never released, causing a reference leak. A reference for the new parent was never acquired, creating the risk of a reference underflow later in ceph_mdsc_release_request(). This patch corrects the logic by releasing the pin from the old parent and acquiring it for the new parent when r_parent is switched. This ensures reference accounting stays balanced. ]

Description: In the Linux kernel, the following vulnerability has been resolved:net: mscc: ocelot: Fix use-after-free caused by cyclic delayed workThe origin code calls cancel_delayed_work() in ocelot_stats_deinit()to cancel the cyclic delayed work item ocelot->stats_work. However,cancel_delayed_work() may fail to cancel the work item if it is alreadyexecuting. While destroy_workqueue() does wait for all pending work itemsin the work queue to complete before destroying the work queue, it cannotprevent the delayed work item from being rescheduled within theocelot_check_stats_work() function. This limitation exists because thedelayed work item is only enqueued into the work queue after its timerexpires. Before the timer expiration, destroy_workqueue() has no visibilityof this pending work item. Once the work queue appears empty,destroy_workqueue() proceeds with destruction.

CVE-2025-66471 Severity: Moderate CVSS3 score: 5.3

Description: urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.0 and prior to 2.6.0, the Streaming API improperly handles highly compressed data. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. When streaming a compressed response, urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header (e.g., gzip, deflate, br, or zstd). The library must read compressed data from the network and decompress it until the requested chunk size is met. Any resulting decompressed data that exceeds the requested amount is held in an internal buffer for the next read operation. The decompression logic could cause urllib3 to fully decode a small amount of highly compressed data in a single operation. This can result in excessive resource consumption (high CPU usage and massive memory allocation for the decompressed data.

CVE-2025-69418 Severity: Moderate CVSS3 score: 5.3

Description: Issue summary: When using the low-level OCB API directly with AES-NI or
other hardware-accelerated code paths, inputs whose length is not a multiple
of 16 bytes can leave the final partial block unencrypted and unauthenticated.

Impact summary: The trailing 1-15 bytes of a message may be exposed in
cleartext on encryption and are not covered by the authentication tag,
allowing an attacker to read or tamper with those bytes without detection.

The low-level OCB encrypt and decrypt routines in the hardware-accelerated
stream path process full 16-byte blocks but do not advance the input/output
pointers. The subsequent tail-handling code then operates on the original
base pointers, effectively reprocessing the beginning of the buffer while
leaving the actual trailing bytes unprocessed. The authentication checksum
also excludes the true tail bytes.

However, typical OpenSSL consumers using EVP are not affected because the
higher-level EVP and provider OCB implementations split inputs so that full
blocks and trailing partial blocks are processed in separate calls, avoiding
the problematic code path. Additionally, TLS does not use OCB ciphersuites.
The vulnerability only affects applications that call the low-level
CRYPTO_ocb128_encrypt() or CRYPTO_ocb128_decrypt() functions directly with
non-block-aligned lengths in a single call on hardware-accelerated builds.
For these reasons the issue was assessed as Low severity.

The FIPS modules in 3.6, 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected
by this issue, as OCB mode is not a FIPS-approved algorithm.

Description: In the Linux kernel, the following vulnerability has been resolved:md: suspend array while updating raid_disks via sysfsIn raid1_reshape(), freeze_array() is called before modifying the r1biomemory pool (conf->r1bio_pool) and conf->raid_disks, andunfreeze_array() is called after the update is completed.However, freeze_array() only waits until nr_sync_pending and(nr_pending - nr_queued) of all buckets reaches zero. When an I/O erroroccurs, nr_queued is increased and the corresponding r1bio is queued toeither retry_list or bio_end_io_list. As a result, freeze_array() mayunblock before these r1bios are released.This can lead to a situation where conf->raid_disks and the mempool havealready been updated while queued r1bios, allocated with the oldraid_disks value, are later released. Consequently, free_r1bio() mayaccess memory out of bounds in put_all_bios() and release r1bios of thewrong size to the new mempool, potentially causing issues with themempool as well.Since only normal I/O might increase nr_queued while an I/O error occurs,suspending the array avoids this issue.Note: Updating raid_disks via ioctl SET_ARRAY_INFO already suspendsthe array. Therefore, we suspend the array when updating raid_disksvia sysfs to avoid this issue too.

Description: In the Linux kernel, the following vulnerability has been resolved:atm: lec: fix null-ptr-deref in lec_arp_clear_vccssyzkaller reported a null-ptr-deref in lec_arp_clear_vccs().This issue can be easily reproduced using the syzkaller reproducer.In the ATM LANE (LAN Emulation) module, the same atm_vcc can be shared bymultiple lec_arp_table entries (e.g., via entry->vcc or entry->recv_vcc).When the underlying VCC is closed, lec_vcc_close() iterates over allARP entries and calls lec_arp_clear_vccs() for each matched entry.For example, when lec_vcc_close() iterates through the hlists inpriv->lec_arp_empty_ones or other ARP tables:1. In the first iteration, for the first matched ARP entry sharing the VCC,lec_arp_clear_vccs() frees the associated vpriv (which is vcc->user_back)and sets vcc->user_back to NULL.2. In the second iteration, for the next matched ARP entry sharing the sameVCC, lec_arp_clear_vccs() is called again. It obtains a NULL vpriv fromvcc->user_back (via LEC_VCC_PRIV(vcc)) and then attempts to dereference itvia `vcc->pop = vpriv->old_pop`, leading to a null-ptr-deref crash.Fix this by adding a null check for vpriv before dereferencingit. If vpriv is already NULL, it means the VCC has been clearedby a previous call, so we can safely skip the cleanup and justclear the entry's vcc/recv_vcc pointers.The entire cleanup block (including vcc_release_async()) is placed insidethe vpriv guard because a NULL vpriv indicates the VCC has already beenfully released by a prior iteration - repeating the teardown wouldredundantly set flags and trigger callbacks on an already-closing socket.The Fixes tag points to the initial commit because the entry->vcc path hasbeen vulnerable since the original code. The entry->recv_vcc path was lateradded by commit 8d9f73c0ad2f ("atm: fix a memory leak of vcc->user_back")with the same pattern, and both paths are fixed here.

CVE-2026-27601 Severity: Moderate CVSS3 score: 5.3

Description: Underscore.js is a utility-belt library for JavaScript. Prior to 1.13.8, the _.flatten and _.isEqual functions use recursion without a depth limit. Under very specific conditions, detailed below, an attacker could exploit this in a Denial of Service (DoS) attack by triggering a stack overflow. Untrusted input must be used to create a recursive datastructure, for example using JSON.parse, with no enforced depth limit. The datastructure thus created must be passed to _.flatten or _.isEqual. In the case of _.flatten, the vulnerability can only be exploited if it is possible for a remote client to prepare a datastructure that consists of arrays at all levels AND if no finite depth limit is passed as the second argument to _.flatten. In the case of _.isEqual, the vulnerability can only be exploited if there exists a code path in which two distinct datastructures that were submitted by the same remote client are compared using _.isEqual. For example, if a client submits data that are stored in a database, and the same client can later submit another datastructure that is then compared to the data that were saved in the database previously, OR if a client submits a single request, but its data are parsed twice, creating two non-identical but equivalent datastructures that are then compared. Exceptions originating from the call to _.flatten or _.isEqual, as a result of a stack overflow, are not being caught. This vulnerability is fixed in 1.13.8.

Description: Issue summary: During processing of a crafted CMS EnvelopedData messagewith KeyAgreeRecipientInfo a NULL pointer dereference can happen.Impact summary: Applications that process attacker-controlled CMS data maycrash before authentication or cryptographic operations occur resulting inDenial of Service.When a CMS EnvelopedData message that uses KeyAgreeRecipientInfo isprocessed, the optional parameters field of KeyEncryptionAlgorithmIdentifieris examined without checking for its presence. This results in a NULLpointer dereference if the field is missing.Applications and services that call CMS_decrypt() on untrusted input(e.g., S/MIME processing or CMS-based protocols) are vulnerable.The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by thisissue, as the affected code is outside the OpenSSL FIPS module boundary.

CVE-2026-32249 Severity: Moderate CVSS3 score: 5.3

Description: Vim is an open source, command line text editor. From 9.1.0011 to before 9.2.0137, Vim's NFA regex compiler, when encountering a collection containing a combining character as the endpoint of a character range (e.g. [0-0\u05bb]), incorrectly emits the composing bytes of that character as separate NFA states. This corrupts the NFA postfix stack, resulting in NFA_START_COLL having a NULL out1 pointer. When nfa_max_width() subsequently traverses the compiled NFA to estimate match width for the look-behind assertion, it dereferences state->out1->out without a NULL check, causing a segmentation fault. This vulnerability is fixed in 9.2.0137.

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: VMX: Fix crash due to uninitialized current_vmcsKVM enables 'Enlightened VMCS' and 'Enlightened MSR Bitmap' when running asa nested hypervisor on top of Hyper-V. When MSR bitmap is updated,evmcs_touch_msr_bitmap function uses current_vmcs per-cpu variable to markthat the msr bitmap was changed.vmx_vcpu_create() modifies the msr bitmap via vmx_disable_intercept_for_msr-> vmx_msr_bitmap_l01_changed which in the end calls this function. Thefunction checks for current_vmcs if it is null but the check isinsufficient because current_vmcs is not initialized. Because of this, thecode might incorrectly write to the structure pointed by current_vmcs valueleft by another task. Preemption is not disabled, the current task can bepreempted and moved to another CPU while current_vmcs is accessed multipletimes from evmcs_touch_msr_bitmap() which leads to crash.The manipulation of MSR bitmaps by callers happens only for vmcs01 so thesolution is to use vmx->vmcs01.vmcs instead of current_vmcs.

CVE-2025-39901 Severity: Moderate CVSS3 score: 5.1

Description: In the Linux kernel, the following vulnerability has been resolved:i40e: remove read access to debugfs filesThe 'command' and 'netdev_ops' debugfs files are a legacy debugginginterface supported by the i40e driver since its early days by commit02e9c290814c ("i40e: debugfs interface").Both of these debugfs files provide a read handler which is mostly useless,and which is implemented with questionable logic. They both use a static256 byte buffer which is initialized to the empty string. In the case ofthe 'command' file this buffer is literally never used and simply wastesspace. In the case of the 'netdev_ops' file, the last command written issaved here.On read, the files contents are presented as the name of the devicefollowed by a colon and then the contents of their respective staticbuffer. For 'command' this will always be ": ". For 'netdev_ops',this will be ": ". But note the buffer isshared between all devices operated by this module. At best, it is mostlymeaningless information, and at worse it could be accessed simultaneouslyas there doesn't appear to be any locking mechanism.We have also recently received multiple reports for both read functionsabout their use of snprintf and potential overflow that could result inreading arbitrary kernel memory. For the 'command' file, this is definitelyimpossible, since the static buffer is always zero and never written to.For the 'netdev_ops' file, it does appear to be possible, if the usercarefully crafts the command input, it will be copied into the buffer,which could be large enough to cause snprintf to truncate, which thencauses the copy_to_user to read beyond the length of the buffer allocatedby kzalloc.A minimal fix would be to replace snprintf() with scnprintf() which wouldcap the return to the number of bytes written, preventing an overflow. Amore involved fix would be to drop the mostly useless static buffers,saving 512 bytes and modifying the read functions to stop needing those asinput.Instead, lets just completely drop the read access to these files. Theseare debug interfaces exposed as part of debugfs, and I don't believe thatdropping read access will break any script, as the provided output ispretty useless. You can find the netdev name through other more standardinterfaces, and the 'netdev_ops' interface can easily result in garbage ifyou issue simultaneous writes to multiple devices at once.In order to properly remove the i40e_dbg_netdev_ops_buf, we need torefactor its write function to avoid using the static buffer. Instead, usethe same logic as the i40e_dbg_command_write, with an allocated buffer.Update the code to use this instead of the static buffer, and ensure wefree the buffer on exit. This fixes simultaneous writes to 'netdev_ops' onmultiple devices, and allows us to remove the now unused static bufferalong with removing the read access.

Description: In the Linux kernel, the following vulnerability has been resolved:w1: therm: Fix off-by-one buffer overflow in alarms_storeThe sysfs buffer passed to alarms_store() is allocated with 'size + 1'bytes and a NUL terminator is appended. However, the 'size' argumentdoes not account for this extra byte. The original code then allocated'size' bytes and used strcpy() to copy 'buf', which always writes onebyte past the allocated buffer since strcpy() copies until the NULterminator at index 'size'.Fix this by parsing the 'buf' parameter directly using simple_strtoll()without allocating any intermediate memory or string copying. Thisremoves the overflow while simplifying the code.

Description: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. From 1.0.9 to before 1.6.57, passing a pointer obtained from png_get_PLTE, png_get_tRNS, or png_get_hIST back into the corresponding setter on the same png_struct/png_info pair causes the setter to read from freed memory and copy its contents into the replacement buffer. The setter frees the internal buffer before copying from the caller-supplied pointer, which now dangles. The freed region may contain stale data (producing silently corrupted chunk metadata) or data from subsequent heap allocations (leaking unrelated heap contents into the chunk struct). This vulnerability is fixed in 1.6.57.

CVE-2023-52424 Severity: Moderate CVSS3 score: 5.0

Description: The IEEE 802.11 standard sometimes enables an adversary to trick a victim into connecting to an unintended or untrusted network with Home WEP, Home WPA3 SAE-loop. Enterprise 802.1X/EAP, Mesh AMPE, or FILS, aka an "SSID Confusion" issue. This occurs because the SSID is not always used to derive the pairwise master key or session keys, and because there is not a protected exchange of an SSID during a 4-way handshake.

CVE-2025-54770 Severity: Moderate CVSS3 score: 4.9

Description: A vulnerability has been identified in the GRUB2 bootloader's network module that poses an immediate Denial of Service (DoS) risk. This flaw is a Use-after-Free issue, caused because the net_set_vlan command is not properly unregistered when the network module is unloaded from memory. An attacker who can execute this command can force the system to access memory locations that are no longer valid. Successful exploitation leads directly to system instability, which can result in a complete crash and halt system availability

Description: In the Linux kernel, the following vulnerability has been resolved:io-wq: check for wq exit after adding new worker task_workWe check IO_WQ_BIT_EXIT before attempting to create a new worker, andwq exit cancels pending work if we have any. But it's possible to havea race between the two, where creation checks exit finding it not set,but we're in the process of exiting. The exit side will cancel pendingcreation task_work, but there's a gap where we add task_work after we'vecanceled existing creations at exit time.Fix this by checking the EXIT bit post adding the creation task_work.If it's set, run the same cancelation that exit does.

CVE-2022-49052 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:mm: fix unexpected zeroed page mapping with zram swapTwo processes under CLONE_VM cloning, user process can be corrupted byseeing zeroed page unexpectedly. CPU A CPU B do_swap_page do_swap_page SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path swap_readpage valid data swap_slot_free_notify delete zram entry swap_readpage zeroed(invalid) data pte_lock map the *zero data* to userspace pte_unlock pte_lock if (!pte_same) goto out_nomap; pte_unlock return and next refault will read zeroed dataThe swap_slot_free_notify is bogus for CLONE_VM case since it doesn'tincrease the refcount of swap slot at copy_mm so it couldn't catch upwhether it's safe or not to discard data from backing device. In thecase, only the lock it could rely on to synchronize swap slot freeing ispage table lock. Thus, this patch gets rid of the swap_slot_free_notifyfunction. With this patch, CPU A will see correct data. CPU A CPU B do_swap_page do_swap_page SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path swap_readpage original data pte_lock map the original data swap_free swap_range_free bd_disk->fops->swap_slot_free_notify swap_readpage read zeroed data pte_unlock pte_lock if (!pte_same) goto out_nomap; pte_unlock return on next refault will see mapped data by CPU BThe concern of the patch would increase memory consumption since itcould keep wasted memory with compressed form in zram as well asuncompressed form in address space. However, most of cases of zram usesno readahead and do_swap_page is followed by swap_free so it will freethe compressed form from in zram quickly.

Moreover, if alloc_skb() fails, urb->context becomesNULL but rx_buf is not freed and there can be a memory leak.The patch removes unnecessary nskb and makes skb processing more clear: itis supposed that ath9k_htc_rx_msg() either frees old skb or passes itsmanaging to another callback function.Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Description: In the Linux kernel, the following vulnerability has been resolved:media: rkisp1: Fix IRQ disable race issueIn rkisp1_isp_stop() and rkisp1_csi_disable() the driver masks theinterrupts and then apparently assumes that the interrupt handler won'tbe running, and proceeds in the stop procedure. This is not the case, asthe interrupt handler can already be running, which would lead to theISP being disabled while the interrupt handler handling a capturedframe.This brings up two issues: 1) the ISP could be powered off while theinterrupt handler is still running and accessing registers, leading toboard lockup, and 2) the interrupt handler code and the code thatdisables the streaming might do things that conflict.It is not clear to me if 2) causes a real issue, but 1) can be seen witha suitable delay (or printk in my case) in the interrupt handler,leading to board lockup.

Fix the issueby moving the flag check inside the section protected byuplink_priv->unready_flows_lock mutex.[0]:[44376.389654] general protection fault, probably for non-canonical address 0xdead000000000108: 0000 [#1] SMP[44376.391665] CPU: 7 PID: 59123 Comm: tc Not tainted 6.4.0-rc4+ #1[44376.392984] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014[44376.395342] RIP: 0010:mlx5e_tc_del_fdb_flow+0xb3/0x340 [mlx5_core][44376.396857] Code: 00 48 8b b8 68 ce 02 00 e8 8a 4d 02 00 4c 8d a8 a8 01 00 00 4c 89 ef e8 8b 79 88 e1 48 8b 83 98 06 00 00 48 8b 93 90 06 00 00 <48> 89 42 08 48 89 10 48 b8 00 01 00 00 00 00 ad de 48 89 83 90 06[44376.399167] RSP: 0018:ffff88812cc97570 EFLAGS: 00010246[44376.399680] RAX: dead000000000122 RBX: ffff8881088e3800 RCX: ffff8881881bac00[44376.400337] RDX: dead000000000100 RSI: ffff88812cc97500 RDI: ffff8881242f71b0[44376.401001] RBP: ffff88811cbb0940 R08: 0000000000000400 R09: 0000000000000001[44376.401663] R10: 0000000000000001 R11: 0000000000000000 R12: ffff88812c944000[44376.402342] R13: ffff8881242f71a8 R14: ffff8881222b4000 R15: 0000000000000000[44376.402999] FS: 00007f0451104800(0000) GS:ffff88852cb80000(0000) knlGS:0000000000000000[44376.403787] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[44376.404343] CR2: 0000000000489108 CR3: 0000000123a79003 CR4: 0000000000370ea0[44376.405004] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[44376.405665] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[44376.406339] Call Trace:[44376.406651] [44376.406939] ? die_addr+0x33/0x90[44376.407311] ? exc_general_protection+0x192/0x390[44376.407795] ? asm_exc_general_protection+0x22/0x30[44376.408292] ? mlx5e_tc_del_fdb_flow+0xb3/0x340 [mlx5_core][44376.408876] __mlx5e_tc_del_fdb_peer_flow+0xbc/0xe0 [mlx5_core][44376.409482] mlx5e_tc_del_flow+0x42/0x210 [mlx5_core][44376.410055] mlx5e_flow_put+0x25/0x50 [mlx5_core][44376.410529] mlx5e_delete_flower+0x24b/0x350 [mlx5_core][44376.411043] tc_setup_cb_reoffload+0x22/0x80[44376.411462] fl_reoffload+0x261/0x2f0 [cls_flower][44376.411907] ? mlx5e_rep_indr_setup_ft_cb+0x160/0x160 [mlx5_core][44376.412481] ? mlx5e_rep_indr_setup_ft_cb+0x160/0x160 [mlx5_core][44376.413044] tcf_block_playback_offloads+0x76/0x170[44376.413497] tcf_block_unbind+0x7b/0xd0[44376.413881] tcf_block_setup+0x17d/0x1c0[44376.414269] tcf_block_offload_cmd.isra.0+0xf1/0x130[44376.414725] tcf_block_offload_unbind+0x43/0x70[44376.415153] __tcf_block_put+0x82/0x150[44376.415532] ingress_destroy+0x22/0x30 [sch_ingress][44376.415986] qdisc_destroy+0x3b/0xd0[44376.416343] qdisc_graft+0x4d0/0x620[44376.416706] tc_get_qdisc+0x1c9/0x3b0[44376.417074] rtnetlink_rcv_msg+0x29c/0x390[44376.419978] ? rep_movs_alternative+0x3a/0xa0[44376.420399] ? rtnl_calcit.isra.0+0x120/0x120[44376.420813] netlink_rcv_skb+0x54/0x100[44376.421192] netlink_unicast+0x1f6/0x2c0[44376.421573] netlink_sendmsg+0x232/0x4a0[44376.421980] sock_sendmsg+0x38/0x60[44376.422328] ____sys_sendmsg+0x1d0/0x1e0[44376.422709] ? copy_msghdr_from_user+0x6d/0xa0[44376.423127] ___sys_sendmsg+0x80/0xc0[44376.423495] ? ___sys_recvmsg+0x8b/0xc0[44376.423869] __sys_sendmsg+0x51/0x90[44376.424226] do_syscall_64+0x3d/0x90[44376.424587] entry_SYSCALL_64_after_hwframe+0x46/0xb0[44376.425046] RIP: 0033:0x7f045134f887[44376.425403] Code: 0a 00 f7 d8 64 89 02 48 c7 c0 ff ff ff ff eb b9 0f 1f 00 f3 0f 1e fa 64 8b 04 25 18 00 00 00 85 c0 75 10 b8 2e 00---truncated---

CVE-2023-54072 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: pcm: Fix potential data race at PCM memory allocation helpersThe PCM memory allocation helpers have a sanity check against too manybuffer allocations. However, the check is performed without a properlock and the allocation isn't serialized; this allows user to allocatemore memories than predefined max size.Practically seen, this isn't really a big problem, as it's more orless some "soft limit" as a sanity check, and it's not possible toallocate unlimitedly. But it's still better to address this for moreconsistent behavior.The patch covers the size check in do_alloc_pages() with thecard->memory_mutex, and increases the allocated size there forpreventing the further overflow. When the actual allocation fails,the size is decreased accordingly.

After that wait_event_killable() is interrupted (it returns-ERESTARTSYS), so that 'wq->name.name == NULL' condition may be notsatisfied. Actually, this condition can be satisfied whenautofs_wait_release() or autofs_catatonic_mode() is called and, what isalso important, wait_ctr is decremented in those places. Upon the exit ofautofs_wait(), wait_ctr is decremented to 1. Then the unmounting processbegins: kill_sb calls autofs_catatonic_mode(), which should have freed thewaitqueues, but it only decrements its usage counter to zero which is nota correct behaviour.edit:imkThis description is of course not correct. The umount performed as a resultof an expire is a umount of a mount that has been automounted, it's not theautofs mount itself. They happen independently, usually after everythingmounted within the autofs file system has been expired away. If everythinghasn't been expired away the automount daemon can still exit leaving mountsin place. But expires done in both cases will result in a notification thatcalls autofs_wait_release() with a result status. The problem case is thesummary execution of of the automount daemon. In this case any waitingprocesses won't be woken up until either they are terminated or the mountis umounted.end edit: imkSo in catatonic mode we should free waitqueues which counter becomes zero.edit: imkInitially I was concerned that the calling of autofs_wait_release() andautofs_catatonic_mode() was not mutually exclusive but that can't be thecase (obviously) because the queue entry (or entries) is removed from thelist when either of these two functions are called. Consequently the waitentry will be freed by only one of these functions or by the woken processin autofs_wait() depending on the order of the calls.end edit: imk

CVE-2023-54158 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: don't free qgroup space unless specifiedBoris noticed in his simple quotas testing that he was getting a leakwith Sweet Tea's change to subvol create that stopped doing atransaction commit. This was just a side effect of that change.In the delayed inode code we have an optimization that will free extrareservations if we think we can pack a dir item into an already modifiedleaf. Previously this wouldn't be triggered in the subvolume createcase because we'd commit the transaction, it was still possible butmuch harder to trigger. It could actually be triggered if we did amkdir && subvol create with qgroups enabled.This occurs because in btrfs_insert_delayed_dir_index(), which getscalled when we're adding the dir item, we do the following: btrfs_block_rsv_release(fs_info, trans->block_rsv, bytes, NULL);if we're able to skip reserving space.The problem here is that trans->block_rsv points at the temporary blockrsv for the subvolume create, which has qgroup reservations in the blockrsv.This is a problem because btrfs_block_rsv_release() will do thefollowing: if (block_rsv->qgroup_rsv_reserved >= block_rsv->qgroup_rsv_size) { qgroup_to_release = block_rsv->qgroup_rsv_reserved - block_rsv->qgroup_rsv_size; block_rsv->qgroup_rsv_reserved = block_rsv->qgroup_rsv_size; }The temporary block rsv just has ->qgroup_rsv_reserved set,->qgroup_rsv_size == 0. The optimization inbtrfs_insert_delayed_dir_index() sets ->qgroup_rsv_reserved = 0. Thenlater on when we call btrfs_subvolume_release_metadata() which has btrfs_block_rsv_release(fs_info, rsv, (u64)-1, &qgroup_to_release); btrfs_qgroup_convert_reserved_meta(root, qgroup_to_release);qgroup_to_release is set to 0, and we do not convert the reservedmetadata space.The problem here is that the block rsv code has been unconditionallymessing with ->qgroup_rsv_reserved, because the main place this is usedis delalloc, and any time we call btrfs_block_rsv_release() we do itwith qgroup_to_release set, and thus do the proper accounting.The subvolume code is the only other code that uses the qgroupreservation stuff, but it's intermingled with the above optimization,and thus was getting its reservation freed out from underneath it andthus leaking the reserved space.The solution is to simply not mess with the qgroup reservations if wedon't have qgroup_to_release set. This works with the existing code asanything that messes with the delalloc reservations always haveqgroup_to_release set. This fixes the leak that Boris was observing.

Description: In the Linux kernel, the following vulnerability has been resolved:igc: Fix Kernel Panic during ndo_tx_timeout callbackThe Xeon validation group has been carrying out some loaded testswith various HW configurations, and they have seen some transmitqueue time out happening during the test. This will cause thereset adapter function to be called by igc_tx_timeout().Similar race conditions may arise when the interface is being broughtdown and up in igc_reinit_locked(), an interrupt being generated, andigc_clean_tx_irq() being called to complete the TX.When the igc_tx_timeout() function is invoked, this patch will turnoff all TX ring HW queues during igc_down() process. TX ring HW queueswill be activated again during the igc_configure_tx_ring() processwhen performing the igc_up() procedure later.This patch also moved existing igc_disable_tx_ring_hw() to avoid usingforward declaration.Kernel trace:[ 7678.747813] ------------[ cut here ]------------[ 7678.757914] NETDEV WATCHDOG: enp1s0 (igc): transmit queue 2 timed out[ 7678.770117] WARNING: CPU: 0 PID: 13 at net/sched/sch_generic.c:525 dev_watchdog+0x1ae/0x1f0[ 7678.784459] Modules linked in: xt_conntrack nft_chain_nat xt_MASQUERADE xt_addrtype nft_compatnf_tables nfnetlink br_netfilter bridge stp llc overlay dm_mod emrcha(PO) emriio(PO) rktpm(PO)cegbuf_mod(PO) patch_update(PO) se(PO) sgx_tgts(PO) mktme(PO) keylocker(PO) svtdx(PO) svfs_pci_hotplug(PO)vtd_mod(PO) davemem(PO) svmabort(PO) svindexio(PO) usbx2(PO) ehci_sched(PO) svheartbeat(PO) ioapic(PO)sv8259(PO) svintr(PO) lt(PO) pcierootport(PO) enginefw_mod(PO) ata(PO) smbus(PO) spiflash_cdf(PO) arden(PO)dsa_iax(PO) oobmsm_punit(PO) cpm(PO) svkdb(PO) ebg_pch(PO) pch(PO) sviotargets(PO) svbdf(PO) svmem(PO)svbios(PO) dram(PO) svtsc(PO) targets(PO) superio(PO) svkernel(PO) cswitch(PO) mcf(PO) pentiumIII_mod(PO)fs_svfs(PO) mdevdefdb(PO) svfs_os_services(O) ixgbe mdio mdio_devres libphy emeraldrapids_svdefs(PO)regsupport(O) libnvdimm nls_cp437 snd_hda_codec_realtek snd_hda_codec_generic ledtrig_audio snd_hda_intelsnd_intel_dspcfg snd_hda_codec snd_hwdep x86_pkg_temp_thermal snd_hda_core snd_pcm snd_timer isst_if_mbox_pci[ 7678.784496] input_leds isst_if_mmio sg snd isst_if_common soundcore wmi button sad9(O) drm fuse backlightconfigfs efivarfs ip_tables x_tables vmd sdhci led_class rtl8150 r8152 hid_generic pegasus mmc_block usbhidmmc_core hid megaraid_sas ixgb igb i2c_algo_bit ice i40e hpsa scsi_transport_sas e1000e e1000 e100 ax88179_178ausbnet xhci_pci sd_mod xhci_hcd t10_pi crc32c_intel crc64_rocksoft igc crc64 crc_t10dif usbcorecrct10dif_generic ptp crct10dif_common usb_common pps_core[ 7679.200403] RIP: 0010:dev_watchdog+0x1ae/0x1f0[ 7679.210201] Code: 28 e9 53 ff ff ff 4c 89 e7 c6 05 06 42 b9 00 01 e8 17 d1 fb ff 44 89 e9 4c89 e6 48 c7 c7 40 ad fb 81 48 89 c2 e8 52 62 82 ff <0f> 0b e9 72 ff ff ff 65 8b 05 80 7d 7c 7e89 c0 48 0f a3 05 0a c1[ 7679.245438] RSP: 0018:ffa00000001f7d90 EFLAGS: 00010282[ 7679.256021] RAX: 0000000000000000 RBX: ff11000109938440 RCX: 0000000000000000[ 7679.268710] RDX: ff11000361e26cd8 RSI: ff11000361e1b880 RDI: ff11000361e1b880[ 7679.281314] RBP: ffa00000001f7da8 R08: ff1100035f8fffe8 R09: 0000000000027ffb[ 7679.293840] R10: 0000000000001f0a R11: ff1100035f840000 R12: ff11000109938000[ 7679.306276] R13: 0000000000000002 R14: dead000000000122 R15: ffa00000001f7e18[ 7679.318648] FS: 0000000000000000(0000) GS:ff11000361e00000(0000) knlGS:0000000000000000[ 7679.332064] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 7679.342757] CR2: 00007ffff7fca168 CR3: 000000013b08a006 CR4: 0000000000471ef8[ 7679.354984] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 7679.367207] DR3: 0000000000000000 DR6: 00000000fffe07f0 DR7: 0000000000000400[ 7679.379370] PKRU: 55555554[ 7679.386446] Call Trace:[ 7679.393152] [ 7679.399363] ? __pfx_dev_watchdog+0x10/0x10[ 7679.407870] call_timer_fn+0x31/0x110[ 7679.415698] e---truncated---

This was reportedby syzbot and the lockdep splat is the following: WARNING: possible circular locking dependency detected 6.5.0-rc7-syzkaller-00024-g93f5de5f648d #0 Not tainted ------------------------------------------------------ syz-executor.2/13257 is trying to acquire lock: ffff88801835c0c0 (&delayed_node->mutex){+.+.}-{3:3}, at: __btrfs_release_delayed_node+0x9a/0xaa0 fs/btrfs/delayed-inode.c:256 but task is already holding lock: ffff88802a5ab8e8 (btrfs-tree-00){++++}-{3:3}, at: __btrfs_tree_lock+0x3c/0x2a0 fs/btrfs/locking.c:198 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (btrfs-tree-00){++++}-{3:3}: __lock_release kernel/locking/lockdep.c:5475 [inline] lock_release+0x36f/0x9d0 kernel/locking/lockdep.c:5781 up_write+0x79/0x580 kernel/locking/rwsem.c:1625 btrfs_tree_unlock_rw fs/btrfs/locking.h:189 [inline] btrfs_unlock_up_safe+0x179/0x3b0 fs/btrfs/locking.c:239 search_leaf fs/btrfs/ctree.c:1986 [inline] btrfs_search_slot+0x2511/0x2f80 fs/btrfs/ctree.c:2230 btrfs_insert_empty_items+0x9c/0x180 fs/btrfs/ctree.c:4376 btrfs_insert_delayed_item fs/btrfs/delayed-inode.c:746 [inline] btrfs_insert_delayed_items fs/btrfs/delayed-inode.c:824 [inline] __btrfs_commit_inode_delayed_items+0xd24/0x2410 fs/btrfs/delayed-inode.c:1111 __btrfs_run_delayed_items+0x1db/0x430 fs/btrfs/delayed-inode.c:1153 flush_space+0x269/0xe70 fs/btrfs/space-info.c:723 btrfs_async_reclaim_metadata_space+0x106/0x350 fs/btrfs/space-info.c:1078 process_one_work+0x92c/0x12c0 kernel/workqueue.c:2600 worker_thread+0xa63/0x1210 kernel/workqueue.c:2751 kthread+0x2b8/0x350 kernel/kthread.c:389 ret_from_fork+0x2e/0x60 arch/x86/kernel/process.c:145 ret_from_fork_asm+0x11/0x20 arch/x86/entry/entry_64.S:304 -> #0 (&delayed_node->mutex){+.+.}-{3:3}: check_prev_add kernel/locking/lockdep.c:3142 [inline] check_prevs_add kernel/locking/lockdep.c:3261 [inline] validate_chain kernel/locking/lockdep.c:3876 [inline] __lock_acquire+0x39ff/0x7f70 kernel/locking/lockdep.c:5144 lock_acquire+0x1e3/0x520 kernel/locking/lockdep.c:5761 __mutex_lock_common+0x1d8/0x2530 kernel/locking/mutex.c:603 __mutex_lock kernel/locking/mutex.c:747 [inline] mutex_lock_nested+0x1b/0x20 kernel/locking/mutex.c:799 __btrfs_release_delayed_node+0x9a/0xaa0 fs/btrfs/delayed-inode.c:256 btrfs_release_delayed_node fs/btrfs/delayed-inode.c:281 [inline] __btrfs_run_delayed_items+0x2b5/0x430 fs/btrfs/delayed-inode.c:1156 btrfs_commit_transaction+0x859/0x2ff0 fs/btrfs/transaction.c:2276 btrfs_sync_file+0xf56/0x1330 fs/btrfs/file.c:1988 vfs_fsync_range fs/sync.c:188 [inline] vfs_fsync fs/sync.c:202 [inline] do_fsync fs/sync.c:212 [inline] __do_sys_fsync fs/sync.c:220 [inline] __se_sys_fsync fs/sync.c:218 [inline] __x64_sys_fsync+0x196/0x1e0 fs/sync.c:218 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x41/0xc0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcd other info that---truncated---

By moving rcu_assign_pointer() after ctx->sk_proto isinitialized, we can ensure that ctx->sk_proto are visible whenchanging sk->sk_prot.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: lpfc: Move NPIV's transport unregistration to after resource clean upThere are cases after NPIV deletion where the fabric switch still believesthe NPIV is logged into the fabric. This occurs when a vport isunregistered before the Remove All DA_ID CT and LOGO ELS are sent to thefabric.Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs includingthe fabric D_ID, removes the last ndlp reference and frees the ndlp rportobject. This sometimes causes the race condition where the final DA_ID andLOGO are skipped from being sent to the fabric switch.Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_IDand LOGO are sent.

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/rxe: Fix seg fault in rxe_comp_queue_pktIn rxe_comp_queue_pkt() an incoming response packet skb is enqueued to theresp_pkts queue and then a decision is made whether to run the completertask inline or schedule it. Finally the skb is dereferenced to bump a 'hw'performance counter. This is wrong because if the completer task isalready running in a separate thread it may have already processed the skband freed it which can cause a seg fault. This has been observedinfrequently in testing at high scale.This patch fixes this by changing the order of enqueuing the packet untilafter the counter is accessed.

Description: In the Linux kernel, the following vulnerability has been resolved:net: fec: remove .ndo_poll_controller to avoid deadlocksThere is a deadlock issue found in sungem driver, please refer to thecommit ac0a230f719b ("eth: sungem: remove .ndo_poll_controller to avoiddeadlocks"). The root cause of the issue is that netpoll is in atomiccontext and disable_irq() is called by .ndo_poll_controller interfaceof sungem driver, however, disable_irq() might sleep. After analyzingthe implementation of fec_poll_controller(), the fec driver should havethe same issue. Due to the fec driver uses NAPI for TX completions, the.ndo_poll_controller is unnecessary to be implemented in the fec driver,so fec_poll_controller() can be safely removed.

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5: Reload only IB representors upon lag disable/enableOn lag disable, the bond IB device along with all of itsrepresentors are destroyed, and then the slaves' representors get reloaded.In case the slave IB representor load fails, the eswitch error flowunloads all representors, including ethernet representors, where thenetdevs get detached and removed from lag bond. Such flow is inaccurateas the lag driver is not responsible for loading/unloading ethernetrepresentors. Furthermore, the flow described above begins by holdinglag lock to prevent bond changes during disable flow. However, whenreaching the ethernet representors detachment from lag, the lag lock isrequired again, triggering the following deadlock:Call trace:__switch_to+0xf4/0x148__schedule+0x2c8/0x7d0schedule+0x50/0xe0schedule_preempt_disabled+0x18/0x28__mutex_lock.isra.13+0x2b8/0x570__mutex_lock_slowpath+0x1c/0x28mutex_lock+0x4c/0x68mlx5_lag_remove_netdev+0x3c/0x1a0 [mlx5_core]mlx5e_uplink_rep_disable+0x70/0xa0 [mlx5_core]mlx5e_detach_netdev+0x6c/0xb0 [mlx5_core]mlx5e_netdev_change_profile+0x44/0x138 [mlx5_core]mlx5e_netdev_attach_nic_profile+0x28/0x38 [mlx5_core]mlx5e_vport_rep_unload+0x184/0x1b8 [mlx5_core]mlx5_esw_offloads_rep_load+0xd8/0xe0 [mlx5_core]mlx5_eswitch_reload_reps+0x74/0xd0 [mlx5_core]mlx5_disable_lag+0x130/0x138 [mlx5_core]mlx5_lag_disable_change+0x6c/0x70 [mlx5_core] // hold ldev->lockmlx5_devlink_eswitch_mode_set+0xc0/0x410 [mlx5_core]devlink_nl_cmd_eswitch_set_doit+0xdc/0x180genl_family_rcv_msg_doit.isra.17+0xe8/0x138genl_rcv_msg+0xe4/0x220netlink_rcv_skb+0x44/0x108genl_rcv+0x40/0x58netlink_unicast+0x198/0x268netlink_sendmsg+0x1d4/0x418sock_sendmsg+0x54/0x60__sys_sendto+0xf4/0x120__arm64_sys_sendto+0x30/0x40el0_svc_common+0x8c/0x120do_el0_svc+0x30/0xa0el0_svc+0x20/0x30el0_sync_handler+0x90/0xb8el0_sync+0x160/0x180Thus, upon lag enable/disable, load and unload only the IB representorsof the slaves preventing the deadlock mentioned above.While at it, refactor the mlx5_esw_offloads_rep_load() function to havea static helper method for its internal logic, in symmetry with therepresentor unload design.

CVE-2024-38600 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: Fix deadlocks with kctl removals at disconnectionIn snd_card_disconnect(), we set card->shutdown flag at the beginning,call callbacks and do sync for card->power_ref_sleep waiters at theend. The callback may delete a kctl element, and this can lead to adeadlock when the device was in the suspended state. Namely:* A process waits for the power up at snd_power_ref_and_wait() in snd_ctl_info() or read/write() inside card->controls_rwsem.* The system gets disconnected meanwhile, and the driver tries to delete a kctl via snd_ctl_remove*(); it tries to take card->controls_rwsem again, but this is already locked by the above. Since the sleeper isn't woken up, this deadlocks.An easy fix is to wake up sleepers before processing the driverdisconnect callbacks but right after setting the card->shutdown flag.Then all sleepers will abort immediately, and the code flows again.So, basically this patch moves the wait_event() call at the righttiming. While we're at it, just to be sure, call wait_event_all()instead of wait_event(), although we don't use exclusive events onthis queue for now.

This will cause a memory leak.Memory leak issues in ax25_dev_device_down():The reference count of ax25_dev is set to 1 in ax25_dev_device_up() andthen increase the reference count when ax25_dev is added to ax25_dev_list.As a result, the reference count of ax25_dev is 2. But when the device isshutting down. The ax25_dev_device_down() drops the reference count onceor twice depending on if we goto unlock_put or not, which will causememory leak.As for the issue of ax25_addr_ax25dev(), it is impossible for one pointerto be on a list twice. So add a break in ax25_addr_ax25dev(). As for theissue of ax25_dev_device_down(), increase the reference count of ax25_devonce in ax25_dev_device_up() and decrease the reference count of ax25_devafter it is removed from the ax25_dev_list.

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: timer: Set lower bound of start tick timeCurrently ALSA timer doesn't have the lower limit of the start ticktime, and it allows a very small size, e.g. 1 tick with 1ns resolutionfor hrtimer. Such a situation may lead to an unexpected RCU stall,where the callback repeatedly queuing the expire update, as reportedby fuzzer.This patch introduces a sanity check of the timer start tick time, sothat the system returns an error when a too small start size is set.As of this patch, the lower limit is hard-coded to 100us, which issmall enough but can still work somehow.

It was found that all variables in the jffs_inode_infostructure were 5a5a5a5a, except for the first member sem. It is suspected that thesevariables are not initialized because they were set to 5a5a5a5a during memory testing,which is meant to detect uninitialized memory.The sem variable is initialized in thefunction jffs2_i_init_once, while other members are initialized inthe function jffs2_init_inode_info.The function jffs2_init_inode_info is called after iget_locked,but in the iget_locked function, the destroy_inode process is triggered,which releases the inode and consequently, the target member of the inodeis not initialized.In concurrent high pressure scenarios, iget_lockedmay enter the destroy_inode branch as described in the code.Since the destroy_inode functionality of jffs2 only releases the target,the fix method is to set target to NULL in jffs2_i_init_once.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: do not BUG_ON() when freeing tree block after errorWhen freeing a tree block, at btrfs_free_tree_block(), if we fail tocreate a delayed reference we don't deal with the error and just do aBUG_ON(). The error most likely to happen is -ENOMEM, and we have acomment mentioning that only -ENOMEM can happen, but that is not true,because in case qgroups are enabled any error returned frombtrfs_qgroup_trace_extent_post() (can be -EUCLEAN or anything returnedfrom btrfs_search_slot() for example) can be propagated back tobtrfs_free_tree_block().So stop doing a BUG_ON() and return the error to the callers and makethem abort the transaction to prevent leaking space.

So ipsec_lock doesn't have to be spin lock, change it tomutex, and thus the above issue can be resolved.

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: fix i_data_sem unlock order in ext4_ind_migrate()Fuzzing reports a possible deadlock in jbd2_log_wait_commit.This issue is triggered when an EXT4_IOC_MIGRATE ioctl is set to requiresynchronous updates because the file descriptor is opened with O_SYNC.This can lead to the jbd2_journal_stop() function callingjbd2_might_wait_for_commit(), potentially causing a deadlock if theEXT4_IOC_MIGRATE call races with a write(2) system call.This problem only arises when CONFIG_PROVE_LOCKING is enabled. In thiscase, the jbd2_might_wait_for_commit macro locks jbd2_handle in thejbd2_journal_stop function while i_data_sem is locked. This triggerslockdep because the jbd2_journal_start function might also lock the samejbd2_handle simultaneously.Found by Linux Verification Center (linuxtesting.org) with syzkaller.Rule: add

CVE-2024-50163 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Make sure internal and UAPI bpf_redirect flags don't overlapThe bpf_redirect_info is shared between the SKB and XDP redirect paths,and the two paths use the same numeric flag values in the ri->flagsfield (specifically, BPF_F_BROADCAST == BPF_F_NEXTHOP). This means thatif skb bpf_redirect_neigh() is used with a non-NULL params argument and,subsequently, an XDP redirect is performed using the samebpf_redirect_info struct, the XDP path will get confused and end upcrashing, which syzbot managed to trigger.With the stack-allocated bpf_redirect_info, the structure is no longershared between the SKB and XDP paths, so the crash doesn't happenanymore. However, different code paths using identically-numbered flagvalues in the same struct field still seems like a bit of a mess, sothis patch cleans that up by moving the flag definitions together andredefining the three flags in BPF_F_REDIRECT_INTERNAL to not overlapwith the flags used for XDP. It also adds a BUILD_BUG_ON() check to makesure the overlap is not re-introduced by mistake.

Description: In the Linux kernel, the following vulnerability has been resolved:arm64/sve: Discard stale CPU state when handling SVE trapsThe logic for handling SVE traps manipulates saved FPSIMD/SVE stateincorrectly, and a race with preemption can result in a task havingTIF_SVE set and TIF_FOREIGN_FPSTATE clear even though the live CPU stateis stale (e.g. with SVE traps enabled). This has been observed to resultin warnings from do_sve_acc() where SVE traps are not expected whileTIF_SVE is set:| if (test_and_set_thread_flag(TIF_SVE))| WARN_ON(1); /* SVE access shouldn't have trapped */Warnings of this form have been reported intermittently, e.g. https://lore.kernel.org/linux-arm-kernel/CA+G9fYtEGe_DhY2Ms7+L7NKsLYUomGsgqpdBj+QwDLeSg=JhGg@mail.gmail.com/ https://lore.kernel.org/linux-arm-kernel/000000000000511e9a060ce5a45c@google.com/The race can occur when the SVE trap handler is preempted before andafter manipulating the saved FPSIMD/SVE state, starting and ending onthe same CPU, e.g.| void do_sve_acc(unsigned long esr, struct pt_regs *regs)| {| // Trap on CPU 0 with TIF_SVE clear, SVE traps enabled| // task->fpsimd_cpu is 0.| // per_cpu_ptr(&fpsimd_last_state, 0) is task.|| ...|| // Preempted; migrated from CPU 0 to CPU 1.| // TIF_FOREIGN_FPSTATE is set.|| get_cpu_fpsimd_context();|| if (test_and_set_thread_flag(TIF_SVE))| WARN_ON(1); /* SVE access shouldn't have trapped */|| sve_init_regs() {| if (!test_thread_flag(TIF_FOREIGN_FPSTATE)) {| ...| } else {| fpsimd_to_sve(current);| current->thread.fp_type = FP_STATE_SVE;| }| }|| put_cpu_fpsimd_context();|| // Preempted; migrated from CPU 1 to CPU 0.| // task->fpsimd_cpu is still 0| // If per_cpu_ptr(&fpsimd_last_state, 0) is still task then:| // - Stale HW state is reused (with SVE traps enabled)| // - TIF_FOREIGN_FPSTATE is cleared| // - A return to userspace skips HW state restore| }Fix the case where the state is not live and TIF_FOREIGN_FPSTATE is setby calling fpsimd_flush_task_state() to detach from the saved CPUstate. This ensures that a subsequent context switch will not reuse thestale CPU state, and will instead set TIF_FOREIGN_FPSTATE, forcing thenew state to be reloaded from memory prior to a return to userspace.

CVE-2024-53169 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:nvme-fabrics: fix kernel crash while shutting down controllerThe nvme keep-alive operation, which executes at a periodic interval,could potentially sneak in while shutting down a fabric controller.This may lead to a race between the fabric controller admin queuedestroy code path (invoked while shutting down controller) and hw/hctxqueue dispatcher called from the nvme keep-alive async request queuingoperation. This race could lead to the kernel crash shown below:Call Trace: autoremove_wake_function+0x0/0xbc (unreliable) __blk_mq_sched_dispatch_requests+0x114/0x24c blk_mq_sched_dispatch_requests+0x44/0x84 blk_mq_run_hw_queue+0x140/0x220 nvme_keep_alive_work+0xc8/0x19c [nvme_core] process_one_work+0x200/0x4e0 worker_thread+0x340/0x504 kthread+0x138/0x140 start_kernel_thread+0x14/0x18While shutting down fabric controller, if nvme keep-alive request sneaksin then it would be flushed off. The nvme_keep_alive_end_io function isthen invoked to handle the end of the keep-alive operation whichdecrements the admin->q_usage_counter and assuming this is the last/onlyrequest in the admin queue then the admin->q_usage_counter becomes zero.If that happens then blk-mq destroy queue operation (blk_mq_destroy_queue()) which could be potentially running simultaneously on anothercpu (as this is the controller shutdown code path) would forwardprogress and deletes the admin queue. So, now from this point onwardwe are not supposed to access the admin queue resources. However theissue here's that the nvme keep-alive thread running hw/hctx queuedispatch operation hasn't yet finished its work and so it could stillpotentially access the admin queue resource while the admin queue hadbeen already deleted and that causes the above crash.The above kernel crash is regression caused due to changes implementedin commit a54a93d0e359 ("nvme: move stopping keep-alive intonvme_uninit_ctrl()"). Ideally we should stop keep-alive before destroying the admin queue and freeing the admin tagset so that it wouldn't sneakin during the shutdown operation. However we removed the keep alive stopoperation from the beginning of the controller shutdown code path in commita54a93d0e359 ("nvme: move stopping keep-alive into nvme_uninit_ctrl()")and added it under nvme_uninit_ctrl() which executes very late in theshutdown code path after the admin queue is destroyed and its tagset isremoved. So this change created the possibility of keep-alive sneaking inand interfering with the shutdown operation and causing observed kernelcrash.To fix the observed crash, we decided to move nvme_stop_keep_alive() fromnvme_uninit_ctrl() to nvme_remove_admin_tag_set(). This change would ensurethat we don't forward progress and delete the admin queue until the keep-alive operation is finished (if it's in-flight) or cancelled and that wouldhelp contain the race condition explained above and hence avoid the crash.Moving nvme_stop_keep_alive() to nvme_remove_admin_tag_set() instead ofadding nvme_stop_keep_alive() to the beginning of the controller shutdowncode path in nvme_stop_ctrl(), as was the case earlier before commita54a93d0e359 ("nvme: move stopping keep-alive into nvme_uninit_ctrl()"),would help save one callsite of nvme_stop_keep_alive().

Description: In the Linux kernel, the following vulnerability has been resolved:smb: During unmount, ensure all cached dir instances drop their dentryThe unmount process (cifs_kill_sb() calling close_all_cached_dirs()) canrace with various cached directory operations, which ultimately resultsin dentries not being dropped and these kernel BUGs:BUG: Dentry ffff88814f37e358{i=1000000000080,n=/} still in use (2) [unmount of cifs cifs]VFS: Busy inodes after unmount of cifs (cifs)------------[ cut here ]------------kernel BUG at fs/super.c:661!This happens when a cfid is in the process of being cleaned up when, andhas been removed from the cfids->entries list, including:- Receiving a lease break from the server- Server reconnection triggers invalidate_all_cached_dirs(), which removes all the cfids from the list- The laundromat thread decides to expire an old cfid.To solve these problems, dropping the dentry is done in queued work donein a newly-added cfid_put_wq workqueue, and close_all_cached_dirs()flushes that workqueue after it drops all the dentries of which it'saware. This is a global workqueue (rather than scoped to a mount), butthe queued work is minimal.The final cleanup work for cleaning up a cfid is performed via workqueued in the serverclose_wq workqueue; this is done separate fromdropping the dentries so that close_all_cached_dirs() doesn't block onany server operations.Both of these queued works expect to invoked with a cfid reference anda tcon reference to avoid those objects from being freed while the workis ongoing.While we're here, add proper locking to close_all_cached_dirs(), andlocking around the freeing of cfid->dentry.

This reordering prevents the race conditionfrom happening.

CVE-2024-56700 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:media: wl128x: Fix atomicity violation in fmc_send_cmd()Atomicity violation occurs when the fmc_send_cmd() function is executedsimultaneously with the modification of the fmdev->resp_skb value.Consider a scenario where, after passing the validity check within thefunction, a non-null fmdev->resp_skb variable is assigned a null value.This results in an invalid fmdev->resp_skb variable passing the validitycheck. As seen in the later part of the function, skb = fmdev->resp_skb;when the invalid fmdev->resp_skb passes the check, a null pointerdereference error may occur at line 478, evt_hdr = (void *)skb->data;To address this issue, it is recommended to include the validity check offmdev->resp_skb within the locked section of the function. Thismodification ensures that the value of fmdev->resp_skb does not changeduring the validation process, thereby maintaining its validity.This possible bug is found by an experimental static analysis tooldeveloped by our team. This tool analyzes the locking APIsto extract function pairs that can be concurrently executed, and thenanalyzes the instructions in the paired functions to identify possibleconcurrency bugs including data races and atomicity violations.

CVE-2024-56780 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:quota: flush quota_release_work upon quota writebackOne of the paths quota writeback is called from is:freeze_super() sync_filesystem() ext4_sync_fs() dquot_writeback_dquots()Since we currently don't always flush the quota_release_work queue inthis path, we can end up with the following race: 1. dquot are added to releasing_dquots list during regular operations. 2. FS Freeze starts, however, this does not flush the quota_release_work queue. 3. Freeze completes. 4. Kernel eventually tries to flush the workqueue while FS is frozen which hits a WARN_ON since transaction gets started during frozen state: ext4_journal_check_start+0x28/0x110 [ext4] (unreliable) __ext4_journal_start_sb+0x64/0x1c0 [ext4] ext4_release_dquot+0x90/0x1d0 [ext4] quota_release_workfn+0x43c/0x4d0Which is the following line: WARN_ON(sb->s_writers.frozen == SB_FREEZE_COMPLETE);Which ultimately results in generic/390 failing due to dmesgnoise. This was detected on powerpc machine 15 cores.To avoid this, make sure to flush the workqueue duringdquot_writeback_dquots() so we dont have any pending workitems afterfreeze.

CVE-2025-21664 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:dm thin: make get_first_thin use rcu-safe list first functionThe documentation in rculist.h explains the absence of list_empty_rcu()and cautions programmers against relying on a list_empty() ->list_first() sequence in RCU safe code. This is because each of thesefunctions performs its own READ_ONCE() of the list head. This can leadto a situation where the list_empty() sees a valid list entry, but thesubsequent list_first() sees a different view of list head state after amodification.In the case of dm-thin, this author had a production box crash from a GPfault in the process_deferred_bios path. This function saw a valid listhead in get_first_thin() but when it subsequently dereferenced that andturned it into a thin_c, it got the inside of the struct pool, since thelist was now empty and referring to itself. The kernel on which thisoccurred printed both a warning about a refcount_t being saturated, anda UBSAN error for an out-of-bounds cpuid access in the queued spinlock,prior to the fault itself. When the resulting kdump was examined, itwas possible to see another thread patiently waiting in thin_dtr'ssynchronize_rcu.The thin_dtr call managed to pull the thin_c out of the active thinslist (and have it be the last entry in the active_thins list) at justthe wrong moment which lead to this crash.Fortunately, the fix here is straight forward. Switch get_first_thin()function to use list_first_or_null_rcu() which performs just a singleREAD_ONCE() and returns NULL if the list is already empty.This was run against the devicemapper test suite's thin-provisioningsuites for delete and suspend and no regressions were observed.

Description: In the Linux kernel, the following vulnerability has been resolved:gpio: aggregator: protect driver attr handlers against module unloadBoth new_device_store and delete_device_store touch module globalresources (e.g. gpio_aggregator_lock). To prevent race conditions withmodule unload, a reference needs to be held.Add try_module_get() in these handlers.For new_device_store, this eliminates what appears to be the most dangerousscenario: if an id is allocated from gpio_aggregator_idr butplatform_device_register has not yet been called or completed, a concurrentmodule unload could fail to unregister/delete the device, leaving behind adangling platform device/GPIO forwarder.

Description: In the Linux kernel, the following vulnerability has been resolved:media: streamzap: fix race between device disconnection and urb callbackSyzkaller has reported a general protection fault at functionir_raw_event_store_with_filter(). This crash is caused by a NULL pointerdereference of dev->raw pointer, even though it is checked for NULL inthe same function, which means there is a race condition. It occurs dueto the incorrect order of actions in the streamzap_disconnect() function:rc_unregister_device() is called before usb_kill_urb(). The dev->rawpointer is freed and set to NULL in rc_unregister_device(), and onlyafter that usb_kill_urb() waits for in-progress requests to finish.If rc_unregister_device() is called while streamzap_callback() handler isnot finished, this can lead to accessing freed resources. Thusrc_unregister_device() should be called after usb_kill_urb().Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

CVE-2025-22030 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:mm: zswap: fix crypto_free_acomp() deadlock in zswap_cpu_comp_dead()Currently, zswap_cpu_comp_dead() calls crypto_free_acomp() while holdingthe per-CPU acomp_ctx mutex. crypto_free_acomp() then holds scomp_lock(through crypto_exit_scomp_ops_async()).On the other hand, crypto_alloc_acomp_node() holds the scomp_lock (throughcrypto_scomp_init_tfm()), and then allocates memory. If the allocationresults in reclaim, we may attempt to hold the per-CPU acomp_ctx mutex.The above dependencies can cause an ABBA deadlock. For example in thefollowing scenario:(1) Task A running on CPU #1: crypto_alloc_acomp_node() Holds scomp_lock Enters reclaim Reads per_cpu_ptr(pool->acomp_ctx, 1)(2) Task A is descheduled(3) CPU #1 goes offline zswap_cpu_comp_dead(CPU #1) Holds per_cpu_ptr(pool->acomp_ctx, 1)) Calls crypto_free_acomp() Waits for scomp_lock(4) Task A running on CPU #2: Waits for per_cpu_ptr(pool->acomp_ctx, 1) // Read on CPU #1 DEADLOCKSince there is no requirement to call crypto_free_acomp() with the per-CPUacomp_ctx mutex held in zswap_cpu_comp_dead(), move it after the mutex isunlocked. Also move the acomp_request_free() and kfree() calls forconsistency and to avoid any potential sublte locking dependencies in thefuture.With this, only setting acomp_ctx fields to NULL occurs with the mutexheld. This is similar to how zswap_cpu_comp_prepare() only initializesacomp_ctx fields with the mutex held, after performing all allocationsbefore holding the mutex.Opportunistically, move the NULL check on acomp_ctx so that it takes placebefore the mutex dereference.

CVE-2025-37951 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:drm/v3d: Add job to pending list if the reset was skippedWhen a CL/CSD job times out, we check if the GPU has made any progresssince the last timeout. If so, instead of resetting the hardware, we skipthe reset and let the timer get rearmed. This gives long-running jobs achance to complete.However, when `timedout_job()` is called, the job in question is removedfrom the pending list, which means it won't be automatically freed through`free_job()`. Consequently, when we skip the reset and keep the jobrunning, the job won't be freed when it finally completes.This situation leads to a memory leak, as exposed in [1] and [2].Similarly to commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler whenGPU is still active"), this patch ensures the job is put back on thepending list when extending the timeout.

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-audio: Kill timer properly at removalThe USB-audio MIDI code initializes the timer, but in a rare case, thedriver might be freed without the disconnect call. This leaves thetimer in an active state while the assigned object is released viasnd_usbmidi_free(), which ends up with a kernel warning when the debugconfiguration is enabled, as spotted by fuzzer.For avoiding the problem, put timer_shutdown_sync() atsnd_usbmidi_free(), so that the timer can be killed properly.While we're at it, replace the existing timer_delete_sync() at thedisconnect callback with timer_shutdown_sync(), too.

Description: In the Linux kernel, the following vulnerability has been resolved:net: Fix TOCTOU issue in sk_is_readable()sk->sk_prot->sock_is_readable is a valid function pointer when sk residesin a sockmap. After the last sk_psock_put() (which usually happens whensocket is removed from sockmap), sk->sk_prot gets restored andsk->sk_prot->sock_is_readable becomes NULL.This makes sk_is_readable() racy, if the value of sk->sk_prot is reloadedafter the initial check. Which in turn may lead to a null pointerdereference.Ensure the function pointer does not turn NULL after the check.

There is a closely relatedissue which has been fixed:https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d6c1b3599b2feb5c7291f5ac3a36e5fa7cedb234... but, unfortunately, the accepted patch appears to still besusceptible to a null pointer dereference under some interleavings.To trigger the bug, we think that `JFS_SBI(ipbmap->i_sb)->bmap` is setto NULL in `dbFreeBits` and then dereferenced in `jfs_ioc_trim`. Thisbug manifests quite rarely under normal circumstances, but istriggereable from a syz-program.

CVE-2025-38231 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:nfsd: Initialize ssc before laundromat_work to prevent NULL dereferenceIn nfs4_state_start_net(), laundromat_work may access nfsd_ssc throughnfs4_laundromat -> nfsd4_ssc_expire_umount. If nfsd_ssc isn't initialized,this can cause NULL pointer dereference.Normally the delayed start of laundromat_work allows sufficient time fornfsd_ssc initialization to complete. However, when the kernel waits toolong for userspace responses (e.g. in nfs4_state_start_net ->nfsd4_end_grace -> nfsd4_record_grace_done -> nfsd4_cld_grace_done ->cld_pipe_upcall -> __cld_pipe_upcall -> wait_for_completion path), thedelayed work may start before nfsd_ssc initialization finishes.Fix this by moving nfsd_ssc initialization before starting laundromat_work.

If one of thelocks aren't readily available, it may lead to dropping the currentrunqueue lock and reacquiring both the locks at once. During this windowit is possible that the task is already migrated and is running on someother CPU. These cases are already handled. However, if the task ismigrated and has already been executed and another CPU is now trying towake it up (ttwu) such that it is queued again on the runqeue(on_rq is 1) and also if the task was run by the same CPU, then thecurrent checks will pass even though the task was migrated out and is nolonger in the pushable tasks list.Crashes=======This bug resulted in quite a few flavors of crashes triggering kernelpanics with various crash signatures such as assert failures, pagefaults, null pointer dereferences, and queue corruption errors allcoming from scheduler itself.Some of the crashes:-> kernel BUG at kernel/sched/rt.c:1616!

Description: In the Linux kernel, the following vulnerability has been resolved:atm: Release atm_dev_mutex after removing procfs in atm_dev_deregister().syzbot reported a warning below during atm_dev_register().

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: hci_core: Fix use-after-free in vhci_flush()syzbot reported use-after-free in vhci_flush() without repro. [0]From the splat, a thread close()d a vhci file descriptor whileits device was being used by iotcl() on another thread.Once the last fd refcnt is released, vhci_release() callshci_unregister_dev(), hci_free_dev(), and kfree() for structvhci_data, which is set to hci_dev->dev->driver_data.The problem is that there is no synchronisation after unlinkinghdev from hci_dev_list in hci_unregister_dev(). There might beanother thread still accessing the hdev which was fetched beforethe unlink operation.We can use SRCU for such synchronisation.Let's run hci_dev_reset() under SRCU and wait for its completionin hci_unregister_dev().Another option would be to restore hci_dev->destruct(), which wasremoved in commit 587ae086f6e4 ("Bluetooth: Remove unusedhci-destruct cb"). However, this would not be a good solution, aswe should not run hci_unregister_dev() while there are in-flightioctl() requests, which could lead to another data-race KCSAN splat.Note that other drivers seem to have the same problem, for exmaple,virtbt_remove().[0]:BUG: KASAN: slab-use-after-free in skb_queue_empty_lockless include/linux/skbuff.h:1891 [inline]BUG: KASAN: slab-use-after-free in skb_queue_purge_reason+0x99/0x360 net/core/skbuff.c:3937Read of size 8 at addr ffff88807cb8d858 by task syz.1.219/6718CPU: 1 UID: 0 PID: 6718 Comm: syz.1.219 Not tainted 6.16.0-rc1-syzkaller-00196-g08207f42d3ff #0 PREEMPT(full)Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 05/07/2025Call Trace: dump_stack_lvl+0x189/0x250 lib/dump_stack.c:120 print_address_description mm/kasan/report.c:408 [inline] print_report+0xd2/0x2b0 mm/kasan/report.c:521 kasan_report+0x118/0x150 mm/kasan/report.c:634 skb_queue_empty_lockless include/linux/skbuff.h:1891 [inline] skb_queue_purge_reason+0x99/0x360 net/core/skbuff.c:3937 skb_queue_purge include/linux/skbuff.h:3368 [inline] vhci_flush+0x44/0x50 drivers/bluetooth/hci_vhci.c:69 hci_dev_do_reset net/bluetooth/hci_core.c:552 [inline] hci_dev_reset+0x420/0x5c0 net/bluetooth/hci_core.c:592 sock_do_ioctl+0xd9/0x300 net/socket.c:1190 sock_ioctl+0x576/0x790 net/socket.c:1311 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:907 [inline] __se_sys_ioctl+0xf9/0x170 fs/ioctl.c:893 do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline] do_syscall_64+0xfa/0x3b0 arch/x86/entry/syscall_64.c:94 entry_SYSCALL_64_after_hwframe+0x77/0x7fRIP: 0033:0x7fcf5b98e929Code: ff ff c3 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 a8 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007fcf5c7b9038 EFLAGS: 00000246 ORIG_RAX: 0000000000000010RAX: ffffffffffffffda RBX: 00007fcf5bbb6160 RCX: 00007fcf5b98e929RDX: 0000000000000000 RSI: 00000000400448cb RDI: 0000000000000009RBP: 00007fcf5ba10b39 R08: 0000000000000000 R09: 0000000000000000R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000R13: 0000000000000000 R14: 00007fcf5bbb6160 R15: 00007ffd6353d528 Allocated by task 6535: kasan_save_stack mm/kasan/common.c:47 [inline] kasan_save_track+0x3e/0x80 mm/kasan/common.c:68 poison_kmalloc_redzone mm/kasan/common.c:377 [inline] __kasan_kmalloc+0x93/0xb0 mm/kasan/common.c:394 kasan_kmalloc include/linux/kasan.h:260 [inline] __kmalloc_cache_noprof+0x230/0x3d0 mm/slub.c:4359 kmalloc_noprof include/linux/slab.h:905 [inline] kzalloc_noprof include/linux/slab.h:1039 [inline] vhci_open+0x57/0x360 drivers/bluetooth/hci_vhci.c:635 misc_open+0x2bc/0x330 drivers/char/misc.c:161 chrdev_open+0x4c9/0x5e0 fs/char_dev.c:414 do_dentry_open+0xdf0/0x1970 fs/open.c:964 vfs_open+0x3b/0x340 fs/open.c:1094 do_open fs/namei.c:3887 [inline] path_openat+0x2ee5/0x3830 fs/name---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: ath11k: fix node corruption in ar->arvifs listIn current WLAN recovery code flow, ath11k_core_halt() onlyreinitializes the "arvifs" list head. This will cause thelist node immediately following the list head to become aninvalid list node. Because the prev of that node still pointsto the list head "arvifs", but the next of the list head "arvifs"no longer points to that list node.When a WLAN recovery occurs during the execution of a vifremoval, and it happens before the spin_lock_bh(&ar->data_lock)in ath11k_mac_op_remove_interface(), list_del() will detect thepreviously mentioned situation, thereby triggering a kernel panic.The fix is to remove and reinitialize all vif list nodes from thelist head "arvifs" during WLAN halt. The reinitialization is to makethe list nodes valid, ensuring that the list_del() inath11k_mac_op_remove_interface() can execute normally.Call trace:__list_del_entry_valid_or_report+0xb8/0xd0ath11k_mac_op_remove_interface+0xb0/0x27c [ath11k]drv_remove_interface+0x48/0x194 [mac80211]ieee80211_do_stop+0x6e0/0x844 [mac80211]ieee80211_stop+0x44/0x17c [mac80211]__dev_close_many+0xac/0x150__dev_change_flags+0x194/0x234dev_change_flags+0x24/0x6cdevinet_ioctl+0x3a0/0x670inet_ioctl+0x200/0x248sock_do_ioctl+0x60/0x118sock_ioctl+0x274/0x35c__arm64_sys_ioctl+0xac/0xf0invoke_syscall+0x48/0x114...Tested-on: QCA6698AQ hw2.1 PCI WLAN.HSP.1.1-04591-QCAHSPSWPL_V1_V2_SILICONZ_IOE-1

This is problematic becausekzalloc() can trigger fs_reclaim_aqcuire(), which may, in turn, invokemmu_notifier_invalidate_range_start(). This function can lead tomlx5_ib_invalidate_range(), which attempts to acquire umem_mutex again,resulting in a deadlock.The problematic flow: CPU0 | CPU1---------------------------------------|------------------------------------------------mlx5_ib_dereg_mr() | -> revoke_mr() | -> mutex_lock(&umem_odp->umem_mutex) | | mlx5_mkey_cache_init() | -> mutex_lock(&dev->cache.rb_lock) | -> mlx5r_cache_create_ent_locked() | -> kzalloc(GFP_KERNEL) | -> fs_reclaim() | -> mmu_notifier_invalidate_range_start() | -> mlx5_ib_invalidate_range() | -> mutex_lock(&umem_odp->umem_mutex) -> cache_ent_find_and_store() | -> mutex_lock(&dev->cache.rb_lock) |Additionally, when kzalloc() is called from withincache_ent_find_and_store(), we encounter the same deadlock due tore-acquisition of umem_mutex.Solve by releasing umem_mutex in dereg_mr() after umr_revoke_mr()and before acquiring rb_lock. This ensures that we don't holdumem_mutex while performing memory allocations that could triggerthe reclaim path.This change prevents the deadlock by ensuring proper lock ordering andavoiding holding locks during memory allocation operations that couldtrigger the reclaim path.The following lockdep warning demonstrates the deadlock: python3/20557 is trying to acquire lock: ffff888387542128 (&umem_odp->umem_mutex){+.+.}-{4:4}, at: mlx5_ib_invalidate_range+0x5b/0x550 [mlx5_ib] but task is already holding lock: ffffffff82f6b840 (mmu_notifier_invalidate_range_start){+.+.}-{0:0}, at: unmap_vmas+0x7b/0x1a0 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #3 (mmu_notifier_invalidate_range_start){+.+.}-{0:0}: fs_reclaim_acquire+0x60/0xd0 mem_cgroup_css_alloc+0x6f/0x9b0 cgroup_init_subsys+0xa4/0x240 cgroup_init+0x1c8/0x510 start_kernel+0x747/0x760 x86_64_start_reservations+0x25/0x30 x86_64_start_kernel+0x73/0x80 common_startup_64+0x129/0x138 -> #2 (fs_reclaim){+.+.}-{0:0}: fs_reclaim_acquire+0x91/0xd0 __kmalloc_cache_noprof+0x4d/0x4c0 mlx5r_cache_create_ent_locked+0x75/0x620 [mlx5_ib] mlx5_mkey_cache_init+0x186/0x360 [mlx5_ib] mlx5_ib_stage_post_ib_reg_umr_init+0x3c/0x60 [mlx5_ib] __mlx5_ib_add+0x4b/0x190 [mlx5_ib] mlx5r_probe+0xd9/0x320 [mlx5_ib] auxiliary_bus_probe+0x42/0x70 really_probe+0xdb/0x360 __driver_probe_device+0x8f/0x130 driver_probe_device+0x1f/0xb0 __driver_attach+0xd4/0x1f0 bus_for_each_dev+0x79/0xd0 bus_add_driver+0xf0/0x200 driver_register+0x6e/0xc0 __auxiliary_driver_register+0x6a/0xc0 do_one_initcall+0x5e/0x390 do_init_module+0x88/0x240 init_module_from_file+0x85/0xc0 idempotent_init_module+0x104/0x300 __x64_sys_finit_module+0x68/0xc0 do_syscall_64+0x6d/0x140 entry_SYSCALL_64_after_hwframe+0x4b/0x53 -> #1 (&dev->cache.rb_lock){+.+.}-{4:4}: __mutex_lock+0x98/0xf10 __mlx5_ib_dereg_mr+0x6f2/0x890 [mlx5_ib] mlx5_ib_dereg_mr+0x21/0x110 [mlx5_ib] ib_dereg_mr_user+0x85/0x1f0 [ib_core] ---truncated---

If application A's job depends on ascheduled fence from application B's job, and that fence is not properlysignaled during the killing process, application A's dependency cannot becleared.This leads to application A hanging indefinitely while waiting for adependency that will never be resolved. Fix this issue by ensuring thatscheduled fences are properly signaled when an entity is killed, allowingdependent applications to continue execution.

CVE-2025-38538 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:dmaengine: nbpfaxi: Fix memory corruption in probe()The nbpf->chan[] array is allocated earlier in the nbpf_probe() functionand it has "num_channels" elements. These three loops iterate oneelement farther than they should and corrupt memory.The changes to the second loop are more involved. In this case, we'recopying data from the irqbuf[] array into the nbpf->chan[] array. Ifthe data in irqbuf[i] is the error IRQ then we skip it, so the iteratorsare not in sync. I added a check to ensure that we don't go beyond theend of the irqbuf[] array. I'm pretty sure this can't happen, but itseemed harmless to add a check.On the other hand, after the loop has ended there is a check to ensurethat the "chan" iterator is where we expect it to be. In the originalcode we went one element beyond the end of the array so the iteratorwasn't in the correct place and it would always return -EINVAL. However,now it will always be in the correct place. I deleted the check sincewe know the result.

CVE-2025-38544 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: Fix bug due to prealloc collisionWhen userspace is using AF_RXRPC to provide a server, it has to preallocateincoming calls and assign to them call IDs that will be used to threadrelated recvmsg() and sendmsg() together. The preallocated call IDs willautomatically be attached to calls as they come in until the pool is empty.To the kernel, the call IDs are just arbitrary numbers, but userspace canuse the call ID to hold a pointer to prepared structs. In any case, theuser isn't permitted to create two calls with the same call ID (call IDsbecome available again when the call ends) and EBADSLT should result fromsendmsg() if an attempt is made to preallocate a call with an in-use callID.However, the cleanup in the error handling will trigger both assertions inrxrpc_cleanup_call() because the call isn't marked complete and isn'tmarked as having been released.Fix this by setting the call state in rxrpc_service_prealloc_one() and thenmarking it as being released before calling the cleanup function.

Description: In the Linux kernel, the following vulnerability has been resolved:xen: fix UAF in dmabuf_exp_from_pages()[dma_buf_fd() fixes; no preferences regarding the tree it goes through -up to xen folks]As soon as we'd inserted a file reference into descriptor table, anotherthread could close it. That's fine for the case when all we are doing isreturning that descriptor to userland (it's a race, but it's a userlandrace and there's nothing the kernel can do about it). However, if wefollow fd_install() with any kind of access to objects that would bedestroyed on close (be it the struct file itself or anything destroyedby its ->release()), we have a UAF.dma_buf_fd() is a combination of reserving a descriptor and fd_install().gntdev dmabuf_exp_from_pages() calls it and then proceeds to access theobjects destroyed on close - starting with gntdev_dmabuf itself.Fix that by doing reserving descriptor before anything else and dofd_install() only when everything had been set up.

CVE-2025-38637 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:net_sched: skbprio: Remove overly strict queue assertionsIn the current implementation, skbprio enqueue/dequeue contains an assertionthat fails under certain conditions when SKBPRIO is used as a child qdisc underTBF with specific parameters. The failure occurs because TBF sometimes peeks atpackets in the child qdisc without actually dequeuing them when tokens areunavailable.This peek operation creates a discrepancy between the parent and child qdiscqueue length counters. When TBF later receives a high-priority packet,SKBPRIO's queue length may show a different value than what's reflected in itsinternal priority queue tracking, triggering the assertion.The fix removes this overly strict assertions in SKBPRIO, they are notnecessary at all.

Description: In the Linux kernel, the following vulnerability has been resolved:cpufreq: intel_pstate: Fix object lifecycle issue in update_qos_request()The cpufreq_cpu_put() call in update_qos_request() takes place too earlybecause the latter subsequently calls freq_qos_update_request() thatindirectly accesses the policy object in question through the QoS requestobject passed to it.Fortunately, update_qos_request() is called under intel_pstate_driver_lock,so this issue does not matter for changing the intel_pstate operationmode, but it theoretically can cause a crash to occur on CPU device hotremoval (which currently can only happen in virt, but it is formallysupported nevertheless).Address this issue by modifying update_qos_request() to drop thereference to the policy later.

This avoids deadlock.dma-fence_ops::signaled can be called with the fence lock in unknownstate. For radeon, the fence lock is also the wait queue lock. This cancause a self deadlock when signaled() tries to make forward progress onthe wait queue.

Description: In the Linux kernel, the following vulnerability has been resolved:spi: tegra210-quad: Fix timeout handlingWhen the CPU that the QSPI interrupt handler runs on (typically CPU 0)is excessively busy, it can lead to rare cases of the IRQ thread notrunning before the transfer timeout is reached.While handling the timeouts, any pending transfers are cleaned up andthe message that they correspond to is marked as failed, which leavesthe curr_xfer field pointing at stale memory.To avoid this, clear curr_xfer to NULL upon timeout and check for thiscondition when the IRQ thread is finally run.While at it, also make sure to clear interrupts on failure so that newinterrupts can be run.A better, more involved, fix would move the interrupt clearing into ahard IRQ handler. Ideally we would also want to signal that the IRQthread no longer needs to be run after the timeout is hit to avoid theextra check for a valid transfer.

Description: In the Linux kernel, the following vulnerability has been resolved:hfsplus: fix missing hfs_bnode_get() in __hfs_bnode_createWhen sync() and link() are called concurrently, both threads mayenter hfs_bnode_find() without finding the node in the hash tableand proceed to create it.Thread A: hfsplus_write_inode() -> hfsplus_write_system_inode() -> hfs_btree_write() -> hfs_bnode_find(tree, 0) -> __hfs_bnode_create(tree, 0)Thread B: hfsplus_create_cat() -> hfs_brec_insert() -> hfs_bnode_split() -> hfs_bmap_alloc() -> hfs_bnode_find(tree, 0) -> __hfs_bnode_create(tree, 0)In this case, thread A creates the bnode, sets refcnt=1, and hashes it.Thread B also tries to create the same bnode, notices it has alreadybeen inserted, drops its own instance, and uses the hashed one withoutgetting the node.``` node2 = hfs_bnode_findhash(tree, cnid); if (!node2) { <- Thread A hash = hfs_bnode_hash(cnid); node->next_hash = tree->node_hash[hash]; tree->node_hash[hash] = node; tree->node_hash_cnt++; } else { <- Thread B spin_unlock(&tree->hash_lock); kfree(node); wait_event(node2->lock_wq, !test_bit(HFS_BNODE_NEW, &node2->flags)); return node2; }```However, hfs_bnode_find() requires each call to take a reference.Here both threads end up setting refcnt=1. When they later put the node,this triggers:BUG_ON(!atomic_read(&node->refcnt))In this scenario, Thread B in fact finds the node in the hash tablerather than creating a new one, and thus must take a reference.Fix this by calling hfs_bnode_get() when reusing a bnode newly created byanother thread to ensure the refcount is updated correctly.A similar bug was fixed in HFS long ago in commita9dc087fd3c4 ("fix missing hfs_bnode_get() in __hfs_bnode_create")but the same issue remained in HFS+ until now.

CVE-2025-68778 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: don't log conflicting inode if it's a dir moved in the current transactionWe can't log a conflicting inode if it's a directory and it was movedfrom one parent directory to another parent directory in the currenttransaction, as this can result an attempt to have a directory withtwo hard links during log replay, one for the old parent directory andanother for the new parent directory.The following scenario triggers that issue:1) We have directories "dir1" and "dir2" created in a past transaction. Directory "dir1" has inode A as its parent directory;2) We move "dir1" to some other directory;3) We create a file with the name "dir1" in directory inode A;4) We fsync the new file. This results in logging the inode of the new file and the inode for the directory "dir1" that was previously moved in the current transaction. So the log tree has the INODE_REF item for the new location of "dir1";5) We move the new file to some other directory. This results in updating the log tree to included the new INODE_REF for the new location of the file and removes the INODE_REF for the old location. This happens during the rename when we call btrfs_log_new_name();6) We fsync the file, and that persists the log tree changes done in the previous step (btrfs_log_new_name() only updates the log tree in memory);7) We have a power failure;8) Next time the fs is mounted, log replay happens and when processing the inode for directory "dir1" we find a new INODE_REF and add that link, but we don't remove the old link of the inode since we have not logged the old parent directory of the directory inode "dir1".As a result after log replay finishes when we trigger writeback of thesubvolume tree's extent buffers, the tree check will detect that we havea directory a hard link count of 2 and we get a mount failure.The errors and stack traces reported in dmesg/syslog are like this: [ 3845.729764] BTRFS info (device dm-0): start tree-log replay [ 3845.730304] page: refcount:3 mapcount:0 mapping:000000005c8a3027 index:0x1d00 pfn:0x11510c [ 3845.731236] memcg:ffff9264c02f4e00 [ 3845.731751] aops:btree_aops [btrfs] ino:1 [ 3845.732300] flags: 0x17fffc00000400a(uptodate|private|writeback|node=0|zone=2|lastcpupid=0x1ffff) [ 3845.733346] raw: 017fffc00000400a 0000000000000000 dead000000000122 ffff9264d978aea8 [ 3845.734265] raw: 0000000000001d00 ffff92650e6d4738 00000003ffffffff ffff9264c02f4e00 [ 3845.735305] page dumped because: eb page dump [ 3845.735981] BTRFS critical (device dm-0): corrupt leaf: root=5 block=30408704 slot=6 ino=257, invalid nlink: has 2 expect no more than 1 for dir [ 3845.737786] BTRFS info (device dm-0): leaf 30408704 gen 10 total ptrs 17 free space 14881 owner 5 [ 3845.737789] BTRFS info (device dm-0): refs 4 lock_owner 0 current 30701 [ 3845.737792] item 0 key (256 INODE_ITEM 0) itemoff 16123 itemsize 160 [ 3845.737794] inode generation 3 transid 9 size 16 nbytes 16384 [ 3845.737795] block group 0 mode 40755 links 1 uid 0 gid 0 [ 3845.737797] rdev 0 sequence 2 flags 0x0 [ 3845.737798] atime 1764259517.0 [ 3845.737800] ctime 1764259517.572889464 [ 3845.737801] mtime 1764259517.572889464 [ 3845.737802] otime 1764259517.0 [ 3845.737803] item 1 key (256 INODE_REF 256) itemoff 16111 itemsize 12 [ 3845.737805] index 0 name_len 2 [ 3845.737807] item 2 key (256 DIR_ITEM 2363071922) itemoff 16077 itemsize 34 [ 3845.737808] location key (257 1 0) type 2 [ 3845.737810] transid 9 data_len 0 name_len 4 [ 3845.737811] item 3 key (256 DIR_ITEM 2676584006) itemoff 16043 itemsize 34 [ 3845.737813] location key (258 1 0) type 2 [ 3845.737814] transid 9 data_len 0 name_len 4 [ 3845.737815] item 4 key (256 DIR_INDEX 2) itemoff 16009 itemsize 34 [ 3845.737816] location key (257 1 0) type 2 [---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:fsnotify: do not generate ACCESS/MODIFY events on child for special filesinotify/fanotify do not allow users with no read access to a file tosubscribe to events (e.g. IN_ACCESS/IN_MODIFY), but they do allow thesame user to subscribe for watching events on children when the userhas access to the parent directory (e.g. /dev).Users with no read access to a file but with read access to its parentdirectory can still stat the file and see if it was accessed/modifiedvia atime/mtime change.The same is not true for special files (e.g. /dev/null). Users will notgenerally observe atime/mtime changes when other users read/write tospecial files, only when someone sets atime/mtime via utimensat().Align fsnotify events with this stat behavior and do not generateACCESS/MODIFY events to parent watchers on read/write of special files.The events are still generated to parent watchers on utimensat().

Therefore, error routes are notflushed when their nexthop object is deleted: # ip link add name dummy1 up type dummy # ip nexthop add id 1 dev dummy1 # ip route add 198.51.100.1/32 nhid 1 # ip route add blackhole 198.51.100.2/32 nhid 1 # ip nexthop del id 1 # ip route show blackhole 198.51.100.2 nhid 1 dev dummy1As such, they keep holding a reference on the nexthop object which inturn holds a reference on the nexthop device, resulting in a referencecount leak: # ip link del dev dummy1 [ 70.516258] unregister_netdevice: waiting for dummy1 to become free. Usage count = 2Fix by flushing error routes when their nexthop is marked as dead.IPv6 does not suffer from this problem.

CVE-2025-71194 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix deadlock in wait_current_trans() due to ignored transaction typeWhen wait_current_trans() is called during start_transaction(), itcurrently waits for a blocked transaction without considering whetherthe given transaction type actually needs to wait for that particulartransaction state. The btrfs_blocked_trans_types[] array already defineswhich transaction types should wait for which transaction states, butthis check was missing in wait_current_trans().This can lead to a deadlock scenario involving two transactions andpending ordered extents: 1. Transaction A is in TRANS_STATE_COMMIT_DOING state 2. A worker processing an ordered extent calls start_transaction() with TRANS_JOIN 3. join_transaction() returns -EBUSY because Transaction A is in TRANS_STATE_COMMIT_DOING 4. Transaction A moves to TRANS_STATE_UNBLOCKED and completes 5. A new Transaction B is created (TRANS_STATE_RUNNING) 6. The ordered extent from step 2 is added to Transaction B's pending ordered extents 7. Transaction B immediately starts commit by another task and enters TRANS_STATE_COMMIT_START 8. The worker finally reaches wait_current_trans(), sees Transaction B in TRANS_STATE_COMMIT_START (a blocked state), and waits unconditionally 9. However, TRANS_JOIN should NOT wait for TRANS_STATE_COMMIT_START according to btrfs_blocked_trans_types[] 10. Transaction B is waiting for pending ordered extents to complete 11. Deadlock: Transaction B waits for ordered extent, ordered extent waits for Transaction BThis can be illustrated by the following call stacks: CPU0 CPU1 btrfs_finish_ordered_io() start_transaction(TRANS_JOIN) join_transaction() # -EBUSY (Transaction A is # TRANS_STATE_COMMIT_DOING) # Transaction A completes # Transaction B created # ordered extent added to # Transaction B's pending list btrfs_commit_transaction() # Transaction B enters # TRANS_STATE_COMMIT_START # waiting for pending ordered # extents wait_current_trans() # waits for Transaction B # (should not wait!)Task bstore_kv_sync in btrfs_commit_transaction waiting for orderedextents: __schedule+0x2e7/0x8a0 schedule+0x64/0xe0 btrfs_commit_transaction+0xbf7/0xda0 [btrfs] btrfs_sync_file+0x342/0x4d0 [btrfs] __x64_sys_fdatasync+0x4b/0x80 do_syscall_64+0x33/0x40 entry_SYSCALL_64_after_hwframe+0x44/0xa9Task kworker in wait_current_trans waiting for transaction commit: Workqueue: btrfs-syno_nocow btrfs_work_helper [btrfs] __schedule+0x2e7/0x8a0 schedule+0x64/0xe0 wait_current_trans+0xb0/0x110 [btrfs] start_transaction+0x346/0x5b0 [btrfs] btrfs_finish_ordered_io.isra.0+0x49b/0x9c0 [btrfs] btrfs_work_helper+0xe8/0x350 [btrfs] process_one_work+0x1d3/0x3c0 worker_thread+0x4d/0x3e0 kthread+0x12d/0x150 ret_from_fork+0x1f/0x30Fix this by passing the transaction type to wait_current_trans() andchecking btrfs_blocked_trans_types[cur_trans->state] against the giventype before deciding to wait.

In the complete callbackkvaser_usb_read_bulk_callback(), the URBs are processed and resubmitted. Inkvaser_usb_remove_interfaces() the URBs are freed by callingusb_kill_anchored_urbs(&dev->rx_submitted).However, this does not take into account that the USB framework unanchorsthe URB before the complete function is called. This means that once anin-URB has been completed, it is no longer anchored and is ultimately notreleased in usb_kill_anchored_urbs().Fix the memory leak by anchoring the URB in thekvaser_usb_read_bulk_callback() to the dev->rx_submitted anchor.

CVE-2026-23110 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: core: Wake up the error handler when final completions race against each otherThe fragile ordering between marking commands completed or failed sothat the error handler only wakes when the last running commandcompletes or times out has race conditions. These race conditions cancause the SCSI layer to fail to wake the error handler, leaving I/Othrough the SCSI host stuck as the error state cannot advance.First, there is an memory ordering issue within scsi_dec_host_busy().The write which clears SCMD_STATE_INFLIGHT may be reordered with readscounting in scsi_host_busy(). While the local CPU will see its ownwrite, reordering can allow other CPUs in scsi_dec_host_busy() orscsi_eh_inc_host_failed() to see a raised busy count, causing no CPU tosee a host busy equal to the host_failed count.This race condition can be prevented with a memory barrier on the errorpath to force the write to be visible before counting host busycommands.Second, there is a general ordering issue with scsi_eh_inc_host_failed(). Bycounting busy commands before incrementing host_failed, it can race with afinal command in scsi_dec_host_busy(), such that scsi_dec_host_busy() doesnot see host_failed incremented but scsi_eh_inc_host_failed() counts busycommands before SCMD_STATE_INFLIGHT is cleared by scsi_dec_host_busy(),resulting in neither waking the error handler task.This needs the call to scsi_host_busy() to be moved after host_failed isincremented to close the race condition.

CVE-2026-23198 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: Don't clobber irqfd routing type when deassigning irqfdWhen deassigning a KVM_IRQFD, don't clobber the irqfd's copy of the IRQ'srouting entry as doing so breaks kvm_arch_irq_bypass_del_producer() on x86and arm64, which explicitly look for KVM_IRQ_ROUTING_MSI. Instead, tohandle a concurrent routing update, verify that the irqfd is still activebefore consuming the routing information. As evidenced by the x86 andarm64 bugs, and another bug in kvm_arch_update_irqfd_routing() (see below),clobbering the entry type without notifying arch code is surprising anderror prone.As a bonus, checking that the irqfd is active provides a convenientlocation for documenting _why_ KVM must not consume the routing entry foran irqfd that is in the process of being deassigned: once the irqfd isdeleted from the list (which happens *before* the eventfd is detached), itwill no longer receive updates via kvm_irq_routing_update(), and so KVMcould deliver an event using stale routing information (relative toKVM_SET_GSI_ROUTING returning to userspace).As an even better bonus, explicitly checking for the irqfd being activefixes a similar bug to the one the clobbering is trying to prevent: if anirqfd is deactivated, and then its routing is changed,kvm_irq_routing_update() won't invoke kvm_arch_update_irqfd_routing()(because the irqfd isn't in the list). And so if the irqfd is in bypassmode, IRQs will continue to be posted using the old routing information.As for kvm_arch_irq_bypass_del_producer(), clobbering the routing typeresults in KVM incorrectly keeping the IRQ in bypass mode, which isespecially problematic on AMD as KVM tracks IRQs that are being posted toa vCPU in a list whose lifetime is tied to the irqfd.Without the help of KASAN to detect use-after-free, the most commonsympton on AMD is a NULL pointer deref in amd_iommu_update_ga() due tothe memory for irqfd structure being re-allocated and zeroed, resultingin irqfd->irq_bypass_data being NULL when read byavic_update_iommu_vcpu_affinity(): BUG: kernel NULL pointer dereference, address: 0000000000000018 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 40cf2b9067 P4D 40cf2b9067 PUD 408362a067 PMD 0 Oops: Oops: 0000 [#1] SMP CPU: 6 UID: 0 PID: 40383 Comm: vfio_irq_test Tainted: G U W O 6.19.0-smp--5dddc257e6b2-irqfd #31 NONE Tainted: [U]=USER, [W]=WARN, [O]=OOT_MODULE Hardware name: Google, Inc.

This might lead to bandwidth accountingcorruption, as enqueue_task_dl() won't recognize the lock holder asboosted.The scenario occurs when:1. A DEADLINE task (donor) blocks on a PI mutex held by another DEADLINE task (holder), but the holder doesn't inherit parameters (e.g., it already has a shorter deadline)2. sched_setscheduler() changes the holder from DEADLINE to a lower class while still holding the mutex3. The holder should now inherit DEADLINE parameters from the donor and be enqueued with ENQUEUE_REPLENISH, but this doesn't happenFix the issue by introducing __setscheduler_dl_pi(), which detects whena DEADLINE (proper or boosted) task gets setscheduled to a lowerpriority class. In case, the function makes the task inherit DEADLINEparameters of the donoer (pi_se) and sets ENQUEUE_REPLENISH flag toensure proper bandwidth accounting during the next enqueue operation.

CVE-2026-27456 Severity: Moderate CVSS3 score: 4.7

Description: util-linux is a random collection of Linux utilities. Prior to version 2.41.4, a TOCTOU (Time-of-Check-Time-of-Use) vulnerability has been identified in the SUID binary /usr/bin/mount from util-linux. The mount binary, when setting up loop devices, validates the source file path with user privileges via fork() + setuid() + realpath(), but subsequently re-canonicalizes and opens it with root privileges (euid=0) without verifying that the path has not been replaced between both operations. Neither O_NOFOLLOW, nor inode comparison, nor post-open fstat() are employed. This allows a local unprivileged user to replace the source file with a symlink pointing to any root-owned file or device during the race window, causing the SUID binary to open and mount it as root. Exploitation requires an /etc/fstab entry with user,loop options whose path points to a directory where the attacker has write permission, and that /usr/bin/mount has the SUID bit set (the default configuration on virtually all Linux distributions). The impact is unauthorized read access to root-protected files and block devices, including backup images, disk volumes, and any file containing a valid filesystem. This issue has been patched in version 2.41.4.

CVE-2022-49814 Severity: Moderate CVSS3 score: 4.5

Description: In the Linux kernel, the following vulnerability has been resolved:kcm: close race conditions on sk_receive_queuesk->sk_receive_queue is protected by skb queue lock, but for KCMsockets its RX path takes mux->rx_lock to protect more than justskb queue. However, kcm_recvmsg() still only grabs the skb queuelock, so race conditions still exist.We can teach kcm_recvmsg() to grab mux->rx_lock too but this wouldintroduce a potential performance regression as struct kcm_mux canbe shared by multiple KCM sockets.So we have to enforce skb queue lock in requeue_rx_msgs() and handleskb peek case carefully in kcm_wait_data(). Fortunately,skb_recv_datagram() already handles it nicely and is widely used byother sockets, we can just switch to skb_recv_datagram() aftergetting rid of the unnecessary sock lock in kcm_recvmsg() andkcm_splice_read(). Side note: SOCK_DONE is not used by KCM sockets,so it is safe to get rid of this check too.I ran the original syzbot reproducer for 30 min without seeing anyissue.

CVE-2023-52503 Severity: Moderate CVSS3 score: 4.5

Description: In the Linux kernel, the following vulnerability has been resolved:tee: amdtee: fix use-after-free vulnerability in amdtee_close_sessionThere is a potential race condition in amdtee_close_session that maycause use-after-free in amdtee_open_session. For instance, if a sessionhas refcount == 1, and one thread tries to free this session via: kref_put(&sess->refcount, destroy_session);the reference count will get decremented, and the next step would be tocall destroy_session(). However, if in another thread,amdtee_open_session() is called before destroy_session() has completedexecution, alloc_session() may return 'sess' that will be freed uplater in destroy_session() leading to use-after-free inamdtee_open_session.To fix this issue, treat decrement of sess->refcount and removal of'sess' from session list in destroy_session() as a critical section, sothat it is executed atomically.

CVE-2025-37920 Severity: Moderate CVSS3 score: 4.5

Description: In the Linux kernel, the following vulnerability has been resolved:xsk: Fix race condition in AF_XDP generic RX pathMove rx_lock from xsk_socket to xsk_buff_pool.Fix synchronization for shared umem mode ingeneric RX path where multiple sockets sharesingle xsk_buff_pool.RX queue is exclusive to xsk_socket, while FILLqueue can be shared between multiple sockets.This could result in race condition where twoCPU cores access RX path of two different socketssharing the same umem.Protect both queues by acquiring spinlock in sharedxsk_buff_pool.Lock contention may be minimized in the future by someper-thread FQ buffering.It's safe and necessary to move spin_lock_bh(rx_lock)after xsk_rcv_check():* xs->pool and spinlock_init is synchronized by xsk_bind() -> xsk_is_bound() memory barriers.* xsk_rcv_check() may return true at the moment of xsk_release() or xsk_unbind_dev(), however this will not cause any data races or race conditions. xsk_unbind_dev() removes xdp socket from all maps and waits for completion of all outstanding rx operations. Packets in RX path will either complete safely or drop.

CVE-2026-31427 Severity: Moderate CVSS3 score: 4.5

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nf_conntrack_sip: fix use of uninitialized rtp_addr in process_sdpprocess_sdp() declares union nf_inet_addr rtp_addr on the stack andpasses it to the nf_nat_sip sdp_session hook after walking the SDPmedia descriptions. However rtp_addr is only initialized inside themedia loop when a recognized media type with a non-zero port is found.If the SDP body contains no m= lines, only inactive media sections(m=audio 0 ...) or only unrecognized media types, rtp_addr is neverassigned. Despite that, the function still calls hooks->sdp_session()with &rtp_addr, causing nf_nat_sdp_session() to format the stale stackvalue as an IP address and rewrite the SDP session owner and connectionlines with it.With CONFIG_INIT_STACK_ALL_ZERO (default on most distributions) thisresults in the session-level o= and c= addresses being rewritten to0.0.0.0 for inactive SDP sessions. Without stack auto-init therewritten address is whatever happened to be on the stack.Fix this by pre-initializing rtp_addr from the session-level connectionaddress (caddr) when available, and tracking via a have_rtp_addr flagwhether any valid address was established. Skip the sdp_session hookentirely when no valid address exists.

E.g. KVM will encounter a NULL pointer when attempting toadd a vCPU to the per-CPU loaded_vmcss_on_cpu list if userspace is able tocreate a VM before vmx_init() configures said list.

Firstly, the ocfs2 super uses"replay_map" to trace online/offline slots, in order to recover offlineslots during recovery and mount. But when ocfs2_truncate_log_init()returns an error in ocfs2_mount_volume(), the memory of "replay_map" willnot be freed in error handling path. Secondly, the memory of "replay_map"will not be freed if d_make_root() returns an error in ocfs2_fill_super().But the memory of "replay_map" will be freed normally when completingrecovery and mount in ocfs2_complete_mount_recovery().Fix the first problem by adding error handling path to free "replay_map"when ocfs2_truncate_log_init() fails. And fix the second problem bycalling ocfs2_free_replay_slots(osb) in the error handling path"out_dismount". In addition, since ocfs2_free_replay_slots() is static,it is necessary to remove its static attribute and declare it in headerfile.

CVE-2023-53503 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: allow ext4_get_group_info() to failPreviously, ext4_get_group_info() would treat an invalid group numberas BUG(), since in theory it should never happen. However, if amalicious attaker (or fuzzer) modifies the superblock via the blockdevice while it is the file system is mounted, it is possible fors_first_data_block to get set to a very large number. In that case,when calculating the block group of some block number (such as thestarting block of a preallocation region), could result in anunderflow and very large block group number. Then the BUG_ON check inext4_get_group_info() would fire, resutling in a denial of serviceattack that can be triggered by root or someone with write access tothe block device.For a quality of implementation perspective, it's best that even ifthe system administrator does something that they shouldn't, that itwill not trigger a BUG. So instead of BUG'ing, ext4_get_group_info()will call ext4_error and return NULL. We also add fallback code inall of the callers of ext4_get_group_info() that it might NULL.Also, since ext4_get_group_info() was already borderline to be aninline function, un-inline it. The results in a next reduction of thecompiled text size of ext4 by roughly 2k.

CVE-2024-26810 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:vfio/pci: Lock external INTx masking opsMask operations through config space changes to DisINTx may race INTxconfiguration changes via ioctl. Create wrappers that add locking forpaths outside of the core interrupt code.In particular, irq_type is updated holding igate, therefore testingis_intx() requires holding igate. For example clearing DisINTx fromconfig space can otherwise race changes of the interrupt configuration.This aligns interfaces which may trigger the INTx eventfd into twocamps, one side serialized by igate and the other only enabled whileINTx is configured. A subsequent patch introduces synchronization forthe latter flows.

CVE-2024-26812 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:vfio/pci: Create persistent INTx handlerA vulnerability exists where the eventfd for INTx signaling can bedeconfigured, which unregisters the IRQ handler but still allowseventfds to be signaled with a NULL context through the SET_IRQS ioctlor through unmask irqfd if the device interrupt is pending.Ideally this could be solved with some additional locking; the igatemutex serializes the ioctl and config space accesses, and the interrupthandler is unregistered relative to the trigger, but the irqfd pathruns asynchronous to those. The igate mutex cannot be acquired from theatomic context of the eventfd wake function. Disabling the irqfdrelative to the eventfd registration is potentially incompatible withexisting userspace.As a result, the solution implemented here moves configuration of theINTx interrupt handler to track the lifetime of the INTx context objectand irq_type configuration, rather than registration of a particulartrigger eventfd. Synchronization is added between the ioctl path andeventfd_signal() wrapper such that the eventfd trigger can bedynamically updated relative to in-flight interrupts or irqfd callbacks.

If the call to kernfs_find_and_get() fails thenkn will be NULL, so the companion sysfs_unbreak_active_protection()routine won't get called (and would only cause an access violation bytrying to dereference kn->parent if it was called). As a result, thereference to kobj acquired at the start of the function will never bereleased.Fix the leak by adding an explicit kobject_put() call when kn is NULL.

CVE-2024-31076 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:genirq/cpuhotplug, x86/vector: Prevent vector leak during CPU offlineThe absence of IRQD_MOVE_PCNTXT prevents immediate effectiveness ofinterrupt affinity reconfiguration via procfs. Instead, the change isdeferred until the next instance of the interrupt being triggered on theoriginal CPU.When the interrupt next triggers on the original CPU, the new affinity isenforced within __irq_move_irq(). A vector is allocated from the new CPU,but the old vector on the original CPU remains and is not immediatelyreclaimed. Instead, apicd->move_in_progress is flagged, and the reclaimingprocess is delayed until the next trigger of the interrupt on the new CPU.Upon the subsequent triggering of the interrupt on the new CPU,irq_complete_move() adds a task to the old CPU's vector_cleanup list if itremains online. Subsequently, the timer on the old CPU iterates over itsvector_cleanup list, reclaiming old vectors.However, a rare scenario arises if the old CPU is outgoing before theinterrupt triggers again on the new CPU.In that case irq_force_complete_move() is not invoked on the outgoing CPUto reclaim the old apicd->prev_vector because the interrupt isn't currentlyaffine to the outgoing CPU, and irq_needs_fixup() returns false. Eventhough __vector_schedule_cleanup() is later called on the new CPU, itdoesn't reclaim apicd->prev_vector; instead, it simply resets bothapicd->move_in_progress and apicd->prev_vector to 0.As a result, the vector remains unreclaimed in vector_matrix, leading to aCPU vector leak.To address this issue, move the invocation of irq_force_complete_move()before the irq_needs_fixup() call to reclaim apicd->prev_vector, if theinterrupt is currently or used to be affine to the outgoing CPU.Additionally, reclaim the vector in __vector_schedule_cleanup() as well,following a warning message, although theoretically it should never seeapicd->move_in_progress with apicd->prev_cpu pointing to an offline CPU.

Description: In the Linux kernel, the following vulnerability has been resolved:net: openvswitch: fix overwriting ct original tuple for ICMPv6OVS_PACKET_CMD_EXECUTE has 3 main attributes: - OVS_PACKET_ATTR_KEY - Packet metadata in a netlink format. - OVS_PACKET_ATTR_PACKET - Binary packet content. - OVS_PACKET_ATTR_ACTIONS - Actions to execute on the packet.OVS_PACKET_ATTR_KEY is parsed first to populate sw_flow_key structurewith the metadata like conntrack state, input port, recirculation id,etc. Then the packet itself gets parsed to populate the rest of thekeys from the packet headers.Whenever the packet parsing code starts parsing the ICMPv6 header, itfirst zeroes out fields in the key corresponding to Neighbor Discoveryinformation even if it is not an ND packet.It is an 'ipv6.nd' field. However, the 'ipv6' is a union that sharesthe space between 'nd' and 'ct_orig' that holds the original tupleconntrack metadata parsed from the OVS_PACKET_ATTR_KEY.ND packets should not normally have conntrack state, so it's fine toshare the space, but normal ICMPv6 Echo packets or maybe other types ofICMPv6 can have the state attached and it should not be overwritten.The issue results in all but the last 4 bytes of the destinationaddress being wiped from the original conntrack tuple leading toincorrect packet matching and potentially executing wrong actionsin case this packet recirculates within the datapath or goes backto userspace.ND fields should not be accessed in non-ND packets, so not clearingthem should be fine. Executing memset() only for actual ND packets toavoid the issue.Initializing the whole thing before parsing is needed because ND packetmay not contain all the options.The issue only affects the OVS_PACKET_CMD_EXECUTE path and doesn'taffect packets entering OVS datapath from network interfaces, becausein this case CT metadata is populated from skb after the packet isalready parsed.

Description: In the Linux kernel, the following vulnerability has been resolved:epoll: be better about file lifetimesepoll can call out to vfs_poll() with a file pointer that may race withthe last 'fput()'. That would make f_count go down to zero, and whilethe ep->mtx locking means that the resulting file pointer tear-down willbe blocked until the poll returns, it means that f_count is alreadydead, and any use of it won't actually get a reference to the file anymore: it's dead regardless.Make sure we have a valid ref on the file pointer before we call down tovfs_poll() from the epoll routines.

CVE-2024-38605 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: core: Fix NULL module pointer assignment at card initThe commit 81033c6b584b ("ALSA: core: Warn on empty module")introduced a WARN_ON() for a NULL module pointer passed at snd_cardobject creation, and it also wraps the code around it with '#ifdefMODULE'. This works in most cases, but the devils are always indetails. "MODULE" is defined when the target code (i.e. the soundcore) is built as a module; but this doesn't mean that the caller isalso built-in or not. Namely, when only the sound core is built-in(CONFIG_SND=y) while the driver is a module (CONFIG_SND_USB_AUDIO=m),the passed module pointer is ignored even if it's non-NULL, andcard->module remains as NULL. This would result in the missing modulereference up/down at the device open/close, leading to a race with thecode execution after the module removal.For addressing the bug, move the assignment of card->module again outof ifdef. The WARN_ON() is still wrapped with ifdef because themodule can be really NULL when all sound drivers are built-in.Note that we keep 'ifdef MODULE' for WARN_ON(), otherwise it wouldlead to a false-positive NULL module check. Admittedly it won't catchperfectly, i.e. no check is performed when CONFIG_SND=y. But, it's noreal problem as it's only for debugging, and the condition is prettyrare.

CVE-2024-46702 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:thunderbolt: Mark XDomain as unplugged when router is removedI noticed that when we do discrete host router NVM upgrade and it getshot-removed from the PCIe side as a result of NVM firmware authentication,if there is another host connected with enabled paths we hang in tearingthem down. This is due to fact that the Thunderbolt networking driveralso tries to cleanup the paths and ends up blocking intb_disconnect_xdomain_paths() waiting for the domain lock.However, at this point we already cleaned the paths in tb_stop() sothere is really no need for tb_disconnect_xdomain_paths() to do thatanymore. Furthermore it already checks if the XDomain is unplugged andbails out early so take advantage of that and mark the XDomain asunplugged when we remove the parent router.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Remove tst_run from lwt_seg6local_prog_ops.The syzbot reported that the lwt_seg6 related BPF ops can be invokedvia bpf_test_run() without without entering input_action_end_bpf()first.Martin KaFai Lau said that self test for BPF_PROG_TYPE_LWT_SEG6LOCALprobably didn't work since it was introduced in commit 04d4b274e2a("ipv6: sr: Add seg6local action End.BPF"). The reason is that theper-CPU variable seg6_bpf_srh_states::srh is never assigned in the selftest case but each BPF function expects it.Remove test_run for BPF_PROG_TYPE_LWT_SEG6LOCAL.

CVE-2024-47794 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Prevent tailcall infinite loop caused by freplaceThere is a potential infinite loop issue that can occur when using acombination of tail calls and freplace.In an upcoming selftest, the attach target for entry_freplace oftailcall_freplace.c is subprog_tc of tc_bpf2bpf.c, while the tail call inentry_freplace leads to entry_tc. This results in an infinite loop:entry_tc -> subprog_tc -> entry_freplace --tailcall-> entry_tc.The problem arises because the tail_call_cnt in entry_freplace resets tozero each time entry_freplace is executed, causing the tail call mechanismto never terminate, eventually leading to a kernel panic.To fix this issue, the solution is twofold:1. Prevent updating a program extended by an freplace program to a prog_array map.2. Prevent extending a program that is already part of a prog_array map with an freplace program.This ensures that:* If a program or its subprogram has been extended by an freplace program, it can no longer be updated to a prog_array map.* If a program has been added to a prog_array map, neither it nor its subprograms can be extended by an freplace program.Moreover, an extension program should not be tailcalled. As such, return-EINVAL if the program has a type of BPF_PROG_TYPE_EXT when adding it to aprog_array map.Additionally, fix a minor code style issue by replacing eight spaces with atab for proper formatting.

CVE-2024-56599 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: ath10k: avoid NULL pointer error during sdio removeWhen running 'rmmod ath10k', ath10k_sdio_remove() will free sdioworkqueue by destroy_workqueue(). But if CONFIG_INIT_ON_FREE_DEFAULT_ONis set to yes, kernel panic will happen:Call trace: destroy_workqueue+0x1c/0x258 ath10k_sdio_remove+0x84/0x94 sdio_bus_remove+0x50/0x16c device_release_driver_internal+0x188/0x25c device_driver_detach+0x20/0x2cThis is because during 'rmmod ath10k', ath10k_sdio_remove() will callath10k_core_destroy() before destroy_workqueue(). wiphy_dev_release()will finally be called in ath10k_core_destroy(). This function will freestruct cfg80211_registered_device *rdev and all its members, includingwiphy, dev and the pointer of sdio workqueue. Then the pointer of sdioworkqueue will be set to NULL due to CONFIG_INIT_ON_FREE_DEFAULT_ON.After device release, destroy_workqueue() will use NULL pointer then thekernel panic happen.Call trace:ath10k_sdio_remove ->ath10k_core_unregister ...... ->ath10k_core_stop ->ath10k_hif_stop ->ath10k_sdio_irq_disable ->ath10k_hif_power_down ->del_timer_sync(&ar_sdio->sleep_timer) ->ath10k_core_destroy ->ath10k_mac_destroy ->ieee80211_free_hw ->wiphy_free ...... ->wiphy_dev_release ->destroy_workqueueNeed to call destroy_workqueue() before ath10k_core_destroy(), freethe work queue buffer first and then free pointer of work queue byath10k_core_destroy(). This order matches the error path order inath10k_sdio_probe().No work will be queued on sdio workqueue between it is destroyed andath10k_core_destroy() is called. Based on the call_stack above, thereason is:Only ath10k_sdio_sleep_timer_handler(), ath10k_sdio_hif_tx_sg() andath10k_sdio_irq_disable() will queue work on sdio workqueue.Sleep timer will be deleted before ath10k_core_destroy() inath10k_hif_power_down().ath10k_sdio_irq_disable() only be called in ath10k_hif_stop().ath10k_core_unregister() will call ath10k_hif_power_down() to stop hifbus, so ath10k_sdio_hif_tx_sg() won't be called anymore.Tested-on: QCA6174 hw3.2 SDIO WLAN.RMH.4.4.1-00189

The page table itself will be discarded after reporting the "nonzero mapcount".2. The HugeTLB page mapped by the page table miss freeing since we treat the page table as shared and a shared page table will not be unmapped.Fix it by introducing independent PMD page table shared count. Asdescribed by comment, pt_index/pt_mm/pt_frag_refcount are used for s390gmap, x86 pgds and powerpc, pt_share_count is used for x86/arm64/riscvpmds, so we can reuse the field as pt_share_count.

Description: In the Linux kernel, the following vulnerability has been resolved:iommu/amd: Fix potential buffer overflow in parse_ivrs_acpihidThere is a string parsing logic error which can lead to an overflow of hidor uid buffers. Comparing ACPIID_LEN against a total string length doesn'ttake into account the lengths of individual hid and uid buffers so thecheck is insufficient in some cases. For example if the length of hidstring is 4 and the length of the uid string is 260, the length of strwill be equal to ACPIID_LEN + 1 but uid string will overflow uid bufferwhich size is 256.The same applies to the hid string with length 13 and uid string withlength 250.Check the length of hid and uid strings separately to preventbuffer overflow.Found by Linux Verification Center (linuxtesting.org) with SVACE.

Use that flag atk3_udma_glue_reset_rx_chn() to deicide if the FDQ needsto be cleared for every flow or just for flow 0.Fixes the below issue on ti_am65_cpsw_nuss driver on AM62-SK.> ip link set eth1 down> ip link set eth0 down> ethtool -L eth0 rx 8> ip link set eth0 up> modprobe -r ti_am65_cpsw_nuss[ 103.045726] ------------[ cut here ]------------[ 103.050505] k3_knav_desc_pool size 512000 != avail 64000[ 103.050703] WARNING: CPU: 1 PID: 450 at drivers/net/ethernet/ti/k3-cppi-desc-pool.c:33 k3_cppi_desc_pool_destroy+0xa0/0xa8 [k3_cppi_desc_pool][ 103.068810] Modules linked in: ti_am65_cpsw_nuss(-) k3_cppi_desc_pool snd_soc_hdmi_codec crct10dif_ce snd_soc_simple_card snd_soc_simple_card_utils display_connector rtc_ti_k3 k3_j72xx_bandgap tidss drm_client_lib snd_soc_davinci_mcasp drm_dma_helper tps6598x phylink snd_soc_ti_udma rti_wdt drm_display_helper snd_soc_tlv320aic3x_i2c typec at24 phy_gmii_sel snd_soc_ti_edma snd_soc_tlv320aic3x sii902x snd_soc_ti_sdma sa2ul omap_mailbox drm_kms_helper authenc cfg80211 rfkill fuse drm drm_panel_orientation_quirks backlight ip_tables x_tables ipv6 [last unloaded: k3_cppi_desc_pool][ 103.119950] CPU: 1 UID: 0 PID: 450 Comm: modprobe Not tainted 6.13.0-rc7-00001-g9c5e3435fa66 #1011[ 103.119968] Hardware name: Texas Instruments AM625 SK (DT)[ 103.119974] pstate: 80000005 (Nzcv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--)[ 103.119983] pc : k3_cppi_desc_pool_destroy+0xa0/0xa8 [k3_cppi_desc_pool][ 103.148007] lr : k3_cppi_desc_pool_destroy+0xa0/0xa8 [k3_cppi_desc_pool][ 103.154709] sp : ffff8000826ebbc0[ 103.158015] x29: ffff8000826ebbc0 x28: ffff0000090b6300 x27: 0000000000000000[ 103.165145] x26: 0000000000000000 x25: 0000000000000000 x24: ffff0000019df6b0[ 103.172271] x23: ffff0000019df6b8 x22: ffff0000019df410 x21: ffff8000826ebc88[ 103.179397] x20: 000000000007d000 x19: ffff00000a3b3000 x18: 0000000000000000[ 103.186522] x17: 0000000000000000 x16: 0000000000000000 x15: 000001e8c35e1cde[ 103.193647] x14: 0000000000000396 x13: 000000000000035c x12: 0000000000000000[ 103.200772] x11: 000000000000003a x10: 00000000000009c0 x9 : ffff8000826eba20[ 103.207897] x8 : ffff0000090b6d20 x7 : ffff00007728c180 x6 : ffff00007728c100[ 103.215022] x5 : 0000000000000001 x4 : ffff000000508a50 x3 : ffff7ffff6146000[ 103.222147] x2 : 0000000000000000 x1 : e300b4173ee6b200 x0 : 0000000000000000[ 103.229274] Call trace:[ 103.231714] k3_cppi_desc_pool_destroy+0xa0/0xa8 [k3_cppi_desc_pool] (P)[ 103.238408] am65_cpsw_nuss_free_rx_chns+0x28/0x4c [ti_am65_cpsw_nuss][ 103.244942] devm_action_release+0x14/0x20[ 103.249040] release_nodes+0x3c/0x68[ 103.252610] devres_release_all+0x8c/0xdc[ 103.256614] device_unbind_cleanup+0x18/0x60[ 103.260876] device_release_driver_internal+0xf8/0x178[ 103.266004] driver_detach+0x50/0x9c[ 103.269571] bus_remove_driver+0x6c/0xbc[ 103.273485] driver_unregister+0x30/0x60[ 103.277401] platform_driver_unregister+0x14/0x20[ 103.282096] am65_cpsw_nuss_driver_exit+0x18/0xff4 [ti_am65_cpsw_nuss][ 103.288620] __arm64_sys_delete_module+0x17c/0x25c[ 103.293404] invoke_syscall+0x44/0x100[ 103.297149] el0_svc_common.constprop.0+0xc0/0xe0[ 103.301845] do_el0_svc+0x1c/0x28[ 103.305155] el0_svc+0x28/0x98---truncated---

CVE-2025-38100 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:x86/iopl: Cure TIF_IO_BITMAP inconsistenciesio_bitmap_exit() is invoked from exit_thread() when a task exists orwhen a fork fails. In the latter case the exit_thread() cleans upresources which were allocated during fork().io_bitmap_exit() invokes task_update_io_bitmap(), which in turn ends upin tss_update_io_bitmap(). tss_update_io_bitmap() operates on thecurrent task. If current has TIF_IO_BITMAP set, but no bitmap installed,tss_update_io_bitmap() crashes with a NULL pointer dereference.There are two issues, which lead to that problem: 1) io_bitmap_exit() should not invoke task_update_io_bitmap() when the task, which is cleaned up, is not the current task. That's a clear indicator for a cleanup after a failed fork(). 2) A task should not have TIF_IO_BITMAP set and neither a bitmap installed nor IOPL emulation level 3 activated. This happens when a kernel thread is created in the context of a user space thread, which has TIF_IO_BITMAP set as the thread flags are copied and the IO bitmap pointer is cleared. Other than in the failed fork() case this has no impact because kernel threads including IO workers never return to user space and therefore never invoke tss_update_io_bitmap().Cure this by adding the missing cleanups and checks: 1) Prevent io_bitmap_exit() to invoke task_update_io_bitmap() if the to be cleaned up task is not the current task. 2) Clear TIF_IO_BITMAP in copy_thread() unconditionally. For user space forks it is set later, when the IO bitmap is inherited in io_bitmap_share().For paranoia sake, add a warning into tss_update_io_bitmap() to catchthe case, when that code is invoked with inconsistent state.

Some malicious userscould use this information to neutralize kernel ASLR.I made a patch to fix ACPI operand cache leak.

CVE-2025-38591 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Reject narrower access to pointer ctx fieldsThe following BPF program, simplified from a syzkaller repro, causes akernel warning: r0 = *(u8 *)(r1 + 169); exit;With pointer field sk being at offset 168 in __sk_buff. This access isdetected as a narrower read in bpf_skb_is_valid_access because itdoesn't match offsetof(struct __sk_buff, sk). It is therefore allowedand later proceeds to bpf_convert_ctx_access. Note that for the"is_narrower_load" case in the convert_ctx_accesses(), the insn->offis aligned, so the cnt may not be 0 because it matches theoffsetof(struct __sk_buff, sk) in the bpf_convert_ctx_access. However,the target_size stays 0 and the verifier errors with a kernel warning: verifier bug: error during ctx access conversion(1)This patch fixes that to return a proper "invalid bpf_context accessoff=X size=Y" error on the load instruction.The same issue affects multiple other fields in context structures thatallow narrow access. Some other non-affected fields (for sk_msg,sk_lookup, and sockopt) were also changed to use bpf_ctx_range_ptr forconsistency.Note this syzkaller crash was reported in the "Closes" link below, whichused to be about a different bug, fixed incommit fce7bd8e385a ("bpf/verifier: Handle BPF_LOAD_ACQ instructionsin insn_def_regno()"). Because syzbot somehow confused the two bugs,the new crash and repro didn't get reported to the mailing list.

CVE-2025-39706 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amdkfd: Destroy KFD debugfs after destroy KFD wqSince KFD proc content was moved to kernel debugfs, we can't destroy KFDdebugfs before kfd_process_destroy_wq. Move kfd_process_destroy_wq priorto kfd_debugfs_fini to fix a kernel NULL pointer problem. It happenswhen /sys/kernel/debug/kfd was already destroyed in kfd_debugfs_fini butkfd_process_destroy_wq calls kfd_debugfs_remove_process. This line debugfs_remove_recursive(entry->proc_dentry);tries to remove /sys/kernel/debug/kfd/proc/ while/sys/kernel/debug/kfd is already gone. It hangs the kernel by kernelNULL pointer.(cherry picked from commit 0333052d90683d88531558dcfdbf2525cc37c233)

That explains why there is no backref item for thatbytenr and why btrfs check is not reporting anything wrong.But this also shows another problem, as btrfs will do all the orphansubvolume cleanup at a read-write mount.So half-dropped subvolume should not exist after an RW mount, andbalance itself is also exclusive to subvolume cleanup, meaning weshouldn't hit a subvolume half-dropped during relocation.The root cause is, there is no orphan item for this subvolume.In fact there are 5 subvolumes from around 2021 that have the sameproblem.It looks like the original report has some older kernels running, andcaused those zombie subvolumes.Thankfully upstream commit 8d488a8c7ba2 ("btrfs: fix subvolume/snapshotdeletion not triggered on mount") has long fixed the bug.[ENHANCEMENT]For repairing such old fs, btrfs-progs will be enhanced.Considering how delayed the problem will show up (at run delayed reftime) and at that time we have to abort transaction already, it is toolate.Instead here we reject any half-dropped subvolume for reloc tree at theearliest time, preventing confusion and extra time wasted on debuggingsimilar bugs.

CVE-2025-39763 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:ACPI: APEI: send SIGBUS to current task if synchronous memory error not recoveredIf a synchronous error is detected as a result of user-space processtriggering a 2-bit uncorrected error, the CPU will take a synchronouserror exception such as Synchronous External Abort (SEA) on Arm64. Thekernel will queue a memory_failure() work which poisons the relatedpage, unmaps the page, and then sends a SIGBUS to the process, so thata system wide panic can be avoided.However, no memory_failure() work will be queued when abnormalsynchronous errors occur. These errors can include situations likeinvalid PA, unexpected severity, no memory failure config support,invalid GUID section, etc. In such a case, the user-space process willtrigger SEA again. This loop can potentially exceed the platformfirmware threshold or even trigger a kernel hard lockup, leading to asystem reboot.Fix it by performing a force kill if no memory_failure() work is queuedfor synchronous errors.[ rjw: Changelog edits ]

CVE-2025-39958 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:iommu/s390: Make attach succeed when the device was surprise removedWhen a PCI device is removed with surprise hotplug, there may still beattempts to attach the device to the default domain as part of tear downvia (__iommu_release_dma_ownership()), or because the removal happensduring probe (__iommu_probe_device()). In both cases zpci_register_ioat()fails with a cc value indicating that the device handle is invalid. Thisis because the device is no longer part of the instance as far as thehypervisor is concerned.Currently this leads to an error return and s390_iommu_attach_device()fails. This triggers the WARN_ON() in __iommu_group_set_domain_nofail()because attaching to the default domain must never fail.With the device fenced by the hypervisor no DMAs to or from memory arepossible and the IOMMU translations have no effect. Proceed as if theregistration was successful and let the hotplug event handling clean upthe device.This is similar to how devices in the error state are handled sincecommit 59bbf596791b ("iommu/s390: Make attach succeed even if the deviceis in error state") except that for removal the domain will not beregistered later. This approach was also previously discussed at thelink.Handle both cases, error state and removal, in a helper which checks ifthe error needs to be propagated or ignored. Avoid magic numbercondition codes by using the pre-existing, but never used, defines forPCI load/store condition codes and rename them to reflect that theyapply to all PCI instructions.

There was a device discovery/fabric scan inprogress. A module unload was issued which set the UNLOADING flag. Aspart of the discovery, after receiving an interrupt a work queue wasscheduled (which involved a work to be queued). Since the UNLOADINGflag is set, the work item was not allocated and the mapped memory hadto be freed. The free occurred in interrupt context leading to systemcrash. Delay the driver unload until the fabric scan is complete toavoid the crash.

CVE-2026-22981 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:idpf: detach and close netdevs while handling a resetProtect the reset path from callbacks by setting the netdevs to detachedstate and close any netdevs in UP state until the reset handling hascompleted. During a reset, the driver will de-allocate resources for thevport, and there is no guarantee that those will recover, which is why theexisting vport_ctrl_lock does not provide sufficient protection.idpf_detach_and_close() is called right before reset handling. If thereset handling succeeds, the netdevs state is recovered via call toidpf_attach_and_open(). If the reset handling fails the netdevs remaindown. The detach/down calls are protected with RTNL lock to avoid racingwith callbacks. On the recovery side the attach can be done withoutholding the RTNL lock as there are no callbacks expected at that point,due to detach/close always being done first in that flow.The previous logic restoring the netdevs state based on theIDPF_VPORT_UP_REQUESTED flag in the init task is not needed anymore, hencethe removal of idpf_set_vport_state().

Description: In the Linux kernel, the following vulnerability has been resolved:spi: spi-sprd-adi: Fix double free in probe error pathThe driver currently uses spi_alloc_host() to allocate the controllerbut registers it using devm_spi_register_controller().If devm_register_restart_handler() fails, the code jumps to theput_ctlr label and calls spi_controller_put(). However, since thecontroller was registered via a devm function, the device core willautomatically call spi_controller_put() again when the probe fails.This results in a double-free of the spi_controller structure.Fix this by switching to devm_spi_alloc_host() and removing themanual spi_controller_put() call.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amd/pm: Disable MMIO access during SMU Mode 1 resetDuring Mode 1 reset, the ASIC undergoes a reset cycle and becomestemporarily inaccessible via PCIe. Any attempt to access MMIO registersduring this window (e.g., from interrupt handlers or other driver threads)can result in uncompleted PCIe transactions, leading to NMI panics orsystem hangs.To prevent this, set the `no_hw_access` flag to true immediately aftertriggering the reset. This signals other driver components to skipregister accesses while the device is offline.A memory barrier `smp_mb()` is added to ensure the flag update isglobally visible to all cores before the driver enters the sleep/waitstate.(cherry picked from commit 7edb503fe4b6d67f47d8bb0dfafb8e699bb0f8a4)

CVE-2026-23300 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:net: ipv6: fix panic when IPv4 route references loopback IPv6 nexthopWhen a standalone IPv6 nexthop object is created with a loopback device(e.g., "ip -6 nexthop add id 100 dev lo"), fib6_nh_init() misclassifiesit as a reject route. This is because nexthop objects have no destinationprefix (fc_dst=::), causing fib6_is_reject() to match any loopbacknexthop. The reject path skips fib_nh_common_init(), leavingnhc_pcpu_rth_output unallocated. If an IPv4 route later references thisnexthop, __mkroute_output() dereferences NULL nhc_pcpu_rth_output andpanics.Simplify the check in fib6_nh_init() to only match explicit rejectroutes (RTF_REJECT) instead of using fib6_is_reject(). The loopbackpromotion heuristic in fib6_is_reject() is handled separately byip6_route_info_create_nh(). After this change, the three cases behaveas follows:1. Explicit reject route ("ip -6 route add unreachable 2001:db8::/64"): RTF_REJECT is set, enters reject path, skips fib_nh_common_init(). No behavior change.2. Implicit loopback reject route ("ip -6 route add 2001:db8::/32 dev lo"): RTF_REJECT is not set, takes normal path, fib_nh_common_init() is called. ip6_route_info_create_nh() still promotes it to reject afterward. nhc_pcpu_rth_output is allocated but unused, which is harmless.3. Standalone nexthop object ("ip -6 nexthop add id 100 dev lo"): RTF_REJECT is not set, takes normal path, fib_nh_common_init() is called. nhc_pcpu_rth_output is properly allocated, fixing the crash when IPv4 routes reference this nexthop.

CVE-2026-31415 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:ipv6: avoid overflows in ip6_datagram_send_ctl()Yiming Qian reported : I believe I found a locally triggerable kernel bug in the IPv6 sendmsg ancillary-data path that can panic the kernel via `skb_under_panic()` (local DoS). The core issue is a mismatch between: - a 16-bit length accumulator (`struct ipv6_txoptions::opt_flen`, type `__u16`) and - a pointer to the *last* provided destination-options header (`opt->dst1opt`) when multiple `IPV6_DSTOPTS` control messages (cmsgs) are provided. - `include/net/ipv6.h`: - `struct ipv6_txoptions::opt_flen` is `__u16` (wrap possible). (lines 291-307, especially 298) - `net/ipv6/datagram.c:ip6_datagram_send_ctl()`: - Accepts repeated `IPV6_DSTOPTS` and accumulates into `opt_flen` without rejecting duplicates. (lines 909-933) - `net/ipv6/ip6_output.c:__ip6_append_data()`: - Uses `opt->opt_flen + opt->opt_nflen` to compute header sizes/headroom decisions. (lines 1448-1466, especially 1463-1465) - `net/ipv6/ip6_output.c:__ip6_make_skb()`: - Calls `ipv6_push_frag_opts()` if `opt->opt_flen` is non-zero. (lines 1930-1934) - `net/ipv6/exthdrs.c:ipv6_push_frag_opts()` / `ipv6_push_exthdr()`: - Push size comes from `ipv6_optlen(opt->dst1opt)` (based on the pointed-to header). (lines 1179-1185 and 1206-1211) 1. `opt_flen` is a 16-bit accumulator: - `include/net/ipv6.h:298` defines `__u16 opt_flen; /* after fragment hdr */`. 2. `ip6_datagram_send_ctl()` accepts *repeated* `IPV6_DSTOPTS` cmsgs and increments `opt_flen` each time: - In `net/ipv6/datagram.c:909-933`, for `IPV6_DSTOPTS`: - It computes `len = ((hdr->hdrlen + 1) << 3);` - It checks `CAP_NET_RAW` using `ns_capable(net->user_ns, CAP_NET_RAW)`. (line 922) - Then it does: - `opt->opt_flen += len;` (line 927) - `opt->dst1opt = hdr;` (line 928) There is no duplicate rejection here (unlike the legacy `IPV6_2292DSTOPTS` path which rejects duplicates at `net/ipv6/datagram.c:901-904`). If enough large `IPV6_DSTOPTS` cmsgs are provided, `opt_flen` wraps while `dst1opt` still points to a large (2048-byte) destination-options header. In the attached PoC (`poc.c`): - 32 cmsgs with `hdrlen=255` => `len = (255+1)*8 = 2048` - 1 cmsg with `hdrlen=0` => `len = 8` - Total increment: `32*2048 + 8 = 65544`, so `(__u16)opt_flen == 8` - The last cmsg is 2048 bytes, so `dst1opt` points to a 2048-byte header. 3. The transmit path sizes headers using the wrapped `opt_flen`:- In `net/ipv6/ip6_output.c:1463-1465`: - `headersize = sizeof(struct ipv6hdr) + (opt ? opt->opt_flen + opt->opt_nflen : 0) + ...;` With wrapped `opt_flen`, `headersize`/headroom decisions underestimate what will be pushed later. 4.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: ibmvfc: Fix OOB access in ibmvfc_discover_targets_done()A malicious or compromised VIO server can return a num_written value in thediscover targets MAD response that exceeds max_targets. This value isstored directly in vhost->num_targets without validation, and is then usedas the loop bound in ibmvfc_alloc_targets() to index into disc_buf[], whichis only allocated for max_targets entries. Indices at or beyond max_targetsaccess kernel memory outside the DMA-coherent allocation. Theout-of-bounds data is subsequently embedded in Implicit Logout and PLOGIMADs that are sent back to the VIO server, leaking kernel memory.Fix by clamping num_written to max_targets before storing it.

CVE-2026-21441 Severity: Moderate CVSS3 score: 4.3

Description: urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP `Content-Encoding` header (e.g., `gzip`, `deflate`, `br`, or `zstd`). When using the streaming API, the library decompresses only the necessary bytes, enabling partial content consumption. Starting in version 1.22 and prior to version 2.6.3, for HTTP redirect responses, the library would read the entire response body to drain the connection and decompress the content unnecessarily. This decompression occurred even before any read methods were called, and configured read limits did not restrict the amount of decompressed data. As a result, there was no safeguard against decompression bombs. A malicious server could exploit this to trigger excessive resource consumption on the client. Applications and libraries are affected when they stream content from untrusted sources by setting `preload_content=False` when they do not disable redirects. Users should upgrade to at least urllib3 v2.6.3, in which the library does not decode content of redirect responses when `preload_content=False`. If upgrading is not immediately possible, disable redirects by setting `redirect=False` for requests to untrusted source.

Description: In the Linux kernel, the following vulnerability has been resolved:dpaa2-switch: prevent ZERO_SIZE_PTR dereference when num_ifs is zeroThe driver allocates arrays for ports, FDBs, and filter blocks usingkcalloc() with ethsw->sw_attr.num_ifs as the element count. When thedevice reports zero interfaces (either due to hardware configurationor firmware issues), kcalloc(0, ...) returns ZERO_SIZE_PTR (0x10)instead of NULL.Later in dpaa2_switch_probe(), the NAPI initialization unconditionallyaccesses ethsw->ports[0]->netdev, which attempts to dereferenceZERO_SIZE_PTR (address 0x10), resulting in a kernel panic.Add a check to ensure num_ifs is greater than zero after retrievingdevice attributes. This prevents the zero-sized allocations andsubsequent invalid pointer dereference.

Description: In the Linux kernel, the following vulnerability has been resolved:af_netlink: Fix shift out of bounds in group mask calculationWhen a netlink message is received, netlink_recvmsg() fills in the addressof the sender. One of the fields is the 32-bit bitfield nl_groups, whichcarries the multicast group on which the message was received. The leastsignificant bit corresponds to group 1, and therefore the highest groupthat the field can represent is 32. Above that, the UB sanitizer flags theout-of-bounds shift attempts.Which bits end up being set in such case is implementation defined, butit's either going to be a wrong non-zero value, or zero, which is at leastnot misleading. Make the latter choice deterministic by always setting to 0for higher-numbered multicast groups.To get information about membership in groups >= 32, userspace is expectedto use nl_pktinfo control messages[0], which are enabled by NETLINK_PKTINFOsocket option.[0] https://lwn.net/Articles/147608/The way to trigger this issue is e.g. through monitoring the BRVLAN group: # bridge monitor vlan & # ip link add name br type bridgeWhich produces the following citation: UBSAN: shift-out-of-bounds in net/netlink/af_netlink.c:162:19 shift exponent 32 is too large for 32-bit type 'int'

Description: In the Linux kernel, the following vulnerability has been resolved:resource: fix region_intersects() vs add_memory_driver_managed()On a system with CXL memory, the resource tree (/proc/iomem) related toCXL memory may look like something as follows.490000000-50fffffff : CXL Window 0 490000000-50fffffff : region0 490000000-50fffffff : dax0.0 490000000-50fffffff : System RAM (kmem)Because drivers/dax/kmem.c calls add_memory_driver_managed() duringonlining CXL memory, which makes "System RAM (kmem)" a descendant of "CXLWindow X". This confuses region_intersects(), which expects all "SystemRAM" resources to be at the top level of iomem_resource. This can lead tobugs.For example, when the following command line is executed to write somememory in CXL memory range via /dev/mem, $ dd if=data of=/dev/mem bs=$((1 << 10)) seek=$((0x490000000 >> 10)) count=1 dd: error writing '/dev/mem': Bad address 1+0 records in 0+0 records out 0 bytes copied, 0.0283507 s, 0.0 kB/sthe command fails as expected. However, the error code is wrong. Itshould be "Operation not permitted" instead of "Bad address". Moreseriously, the /dev/mem permission checking in devmem_is_allowed() passesincorrectly. Although the accessing is prevented later because ioremap()isn't allowed to map system RAM, it is a potential security issue. Duringcommand executing, the following warning is reported in the kernel log forcalling ioremap() on system RAM. ioremap on RAM at 0x0000000490000000 - 0x0000000490000fff WARNING: CPU: 2 PID: 416 at arch/x86/mm/ioremap.c:216 __ioremap_caller.constprop.0+0x131/0x35d Call Trace: memremap+0xcb/0x184 xlate_dev_mem_ptr+0x25/0x2f write_mem+0x94/0xfb vfs_write+0x128/0x26d ksys_write+0xac/0xfe do_syscall_64+0x9a/0xfd entry_SYSCALL_64_after_hwframe+0x4b/0x53The details of command execution process are as follows. In the aboveresource tree, "System RAM" is a descendant of "CXL Window 0" instead of atop level resource. So, region_intersects() will report no System RAMresources in the CXL memory region incorrectly, because it only checks thetop level resources. Consequently, devmem_is_allowed() will return 1(allow access via /dev/mem) for CXL memory region incorrectly. Fortunately, ioremap() doesn't allow to map System RAM and reject theaccess.So, region_intersects() needs to be fixed to work correctly with theresource tree with "System RAM" not at top level as above. To fix it, ifwe found a unmatched resource in the top level, we will continue to searchmatched resources in its descendant resources. So, we will not miss anymatched resources in resource tree anymore.In the new implementation, an example resource tree|------------- "CXL Window 0" ------------||-- "System RAM" --|will behave similar as the following fake resource tree forregion_intersects(, IORESOURCE_SYSTEM_RAM, ),|-- "System RAM" --||-- "CXL Window 0a" --|Where "CXL Window 0a" is part of the original "CXL Window 0" thatisn't covered by "System RAM".

CVE-2022-49124 Severity: Moderate CVSS3 score: 4.1

Description: In the Linux kernel, the following vulnerability has been resolved:x86/mce: Work around an erratum on fast string copy instructionsA rare kernel panic scenario can happen when the following conditionsare met due to an erratum on fast string copy instructions:1) An uncorrected error.2) That error must be in first cache line of a page.3) Kernel must execute page_copy from the page immediately before thatpage.The fast string copy instructions ("REP; MOVS*") could consume anuncorrectable memory error in the cache line _right after_ the desiredregion to copy and raise an MCE.Bit 0 of MSR_IA32_MISC_ENABLE can be cleared to disable fast stringcopy and will avoid such spurious machine checks. However, that is lesspreferable due to the permanent performance impact. Considering memorypoison is rare, it's desirable to keep fast string copy enabled until anMCE is seen.Intel has confirmed the following:1. The CPU erratum of fast string copy only applies to Skylake,Cascade Lake and Cooper Lake generations.Directly return from the MCE handler:2. Will result in complete execution of the "REP; MOVS*" with no dataloss or corruption.3. Will not result in another MCE firing on the next poisoned cache linedue to "REP; MOVS*".4. Will resume execution from a correct point in code.5. Will result in the same instruction that triggered the MCE firing asecond MCE immediately for any other software recoverable data fetcherrors.6. Is not safe without disabling the fast string copy, as the next faststring copy of the same buffer on the same CPU would result in a PANICMCE.This should mitigate the erratum completely with the only caveat thatthe fast string copy is disabled on the affected hyper thread thusperformance degradation.This is still better than the OS crashing on MCEs raised on anirrelevant process due to "REP; MOVS*' accesses in a kernel context,e.g., copy_page.Injected errors on 1st cache line of 8 anonymous pages of process'proc1' and observed MCE consumption from 'proc2' with no panic(directly returned).Without the fix, the host panicked within a few minutes on arandom 'proc2' process due to kernel access from copy_page.

CVE-2022-50626 Severity: Moderate CVSS3 score: 4.1

Description: In the Linux kernel, the following vulnerability has been resolved:media: dvb-usb: fix memory leak in dvb_usb_adapter_init()Syzbot reports a memory leak in "dvb_usb_adapter_init()".The leak is due to not accounting for and freeing current iteration'sadapter->priv in case of an error. Currently if an error occurs,it will exit before incrementing "num_adapters_initalized",which is used as a reference counter to free all adap->privin "dvb_usb_adapter_exit()". There are multiple error paths thatcan exit from before incrementing the counter. Including theerror handling paths for "dvb_usb_adapter_stream_init()","dvb_usb_adapter_dvb_init()" and "dvb_usb_adapter_frontend_init()"within "dvb_usb_adapter_init()".This means that in case of an error in any of these functions thecurrent iteration is not accounted for and the current iteration'sadap->priv is not freed.Fix this by freeing the current iteration's adap->priv in the"stream_init_err:" label in the error path. The rest of the(accounted for) adap->priv objects are freed in dvb_usb_adapter_exit()as expected using the num_adapters_initalized variable.Syzbot report:BUG: memory leakunreferenced object 0xffff8881172f1a00 (size 512): comm "kworker/0:2", pid 139, jiffies 4294994873 (age 10.960s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................backtrace: [] dvb_usb_adapter_init drivers/media/usb/dvb-usb/dvb-usb-init.c:75 [inline] [] dvb_usb_init drivers/media/usb/dvb-usb/dvb-usb-init.c:184 [inline] [] dvb_usb_device_init.cold+0x4e5/0x79e drivers/media/usb/dvb-usb/dvb-usb-init.c:308 [] dib0700_probe+0x8d/0x1b0 drivers/media/usb/dvb-usb/dib0700_core.c:883 [] usb_probe_interface+0x177/0x370 drivers/usb/core/driver.c:396 [] call_driver_probe drivers/base/dd.c:542 [inline] [] really_probe.part.0+0xe7/0x310 drivers/base/dd.c:621 [] really_probe drivers/base/dd.c:583 [inline] [] __driver_probe_device+0x10c/0x1e0 drivers/base/dd.c:752 [] driver_probe_device+0x2a/0x120 drivers/base/dd.c:782 [] __device_attach_driver+0xf6/0x140 drivers/base/dd.c:899 [] bus_for_each_drv+0xb7/0x100 drivers/base/bus.c:427 [] __device_attach+0x122/0x260 drivers/base/dd.c:970 [] bus_probe_device+0xc6/0xe0 drivers/base/bus.c:487 [] device_add+0x5fb/0xdf0 drivers/base/core.c:3405 [] usb_set_configuration+0x8f2/0xb80 drivers/usb/core/message.c:2170 [] usb_generic_driver_probe+0x8c/0xc0 drivers/usb/core/generic.c:238 [] usb_probe_device+0x5c/0x140 drivers/usb/core/driver.c:293 [] call_driver_probe drivers/base/dd.c:542 [inline] [] really_probe.part.0+0xe7/0x310 drivers/base/dd.c:621 [] really_probe drivers/base/dd.c:583 [inline] [] __driver_probe_device+0x10c/0x1e0 drivers/base/dd.c:752

Description: In the Linux kernel, the following vulnerability has been resolved:power: supply: bq27xxx: Fix poll_interval handling and races on removeBefore this patch bq27xxx_battery_teardown() was setting poll_interval = 0to avoid bq27xxx_battery_update() requeuing the delayed_work item.There are 2 problems with this:1. If the driver is unbound through sysfs, rather then the module being rmmod-ed, this changes poll_interval unexpectedly2. This is racy, after it being set poll_interval could be changed before bq27xxx_battery_update() checks it through /sys/module/bq27xxx_battery/parameters/poll_intervalFix this by added a removed attribute to struct bq27xxx_device_info andusing that instead of setting poll_interval to 0.There also is another poll_interval related race on remove(), writing/sys/module/bq27xxx_battery/parameters/poll_interval will requeuethe delayed_work item for all devices on the bq27xxx_battery_deviceslist and the device being removed was only removed from that listafter cancelling the delayed_work item.Fix this by moving the removal from the bq27xxx_battery_devices listto before cancelling the delayed_work item.

The field is initialized byioc_pd_init() and never cleared. The NULL deref is caused byblkcg_activate_policy() installing blkg_policy_data before initializing it.blkcg_activate_policy() was doing the following:1. Allocate pd's for all existing blkg's and install them in blkg->pd[].2. Initialize all pd's.3. Online all pd's.blkcg_activate_policy() only grabs the queue_lock and may release andre-acquire the lock as allocation may need to sleep. ioc_weight_write()grabs blkcg->lock and iterates all its blkg's. The two can race and ifioc_weight_write() runs during #1 or between #1 and #2, it can encounter apd which is not initialized yet, leading to crash.The crash can be reproduced with the following script: #!/bin/bash echo +io > /sys/fs/cgroup/cgroup.subtree_control systemd-run --unit touch-sda --scope dd if=/dev/sda of=/dev/null bs=1M count=1 iflag=direct echo 100 > /sys/fs/cgroup/system.slice/io.weight bash -c "echo '8:0 enable=1' > /sys/fs/cgroup/io.cost.qos" & sleep .2 echo 100 > /sys/fs/cgroup/system.slice/io.weightwith the following patch applied:> diff --git a/block/blk-cgroup.c b/block/blk-cgroup.c> index fc49be622e05..38d671d5e10c 100644> --- a/block/blk-cgroup.c> +++ b/block/blk-cgroup.c> @@ -1553,6 +1553,12 @@ int blkcg_activate_policy(struct gendisk *disk, const struct blkcg_policy *pol)> pd->online = false;> }>> + if (system_state == SYSTEM_RUNNING) {> + spin_unlock_irq(&q->queue_lock);> + ssleep(1);> + spin_lock_irq(&q->queue_lock);> + }> +> /* all allocated, init in the same order */> if (pol->pd_init_fn)> list_for_each_entry_reverse(blkg, &q->blkg_list, q_node)I don't see a reason why all pd's should be allocated, initialized andonlined together. The only ordering requirement is that parent blkgs to beinitialized and onlined before children, which is guaranteed from thewalking order. Let's fix the bug by allocating, initializing and onlining pdfor each blkg and holding blkcg->lock over initialization and onlining. Thisensures that an installed blkg is always fully initialized and onlinedremoving the the race window.

However, while ltp runningstress tests, it was observed that in case of some error handling paths, it ispossible for update_super_work to start a transaction after the journal isdestroyed eg:(umount)ext4_kill_sb kill_block_super generic_shutdown_super sync_filesystem /* commits all txns */ evict_inodes /* might start a new txn */ ext4_put_super flush_work(&sbi->s_sb_upd_work) /* flush the workqueue */ jbd2_journal_destroy journal_kill_thread journal->j_flags |= JBD2_UNMOUNT; jbd2_journal_commit_transaction jbd2_journal_get_descriptor_buffer jbd2_journal_bmap ext4_journal_bmap ext4_map_blocks ... ext4_inode_error ext4_handle_error schedule_work(&sbi->s_sb_upd_work) /* work queue kicks in */ update_super_work jbd2_journal_start start_this_handle BUG_ON(journal->j_flags & JBD2_UNMOUNT)Hence, introduce a new mount flag to indicate journal is destroying and only doa journaled (and deferred) update of sb if this flag is not set. Otherwise, justfallback to an un-journaled commit.Further, in the journal destroy path, we have the following sequence: 1. Set mount flag indicating journal is destroying 2. force a commit and wait for it 3. flush pending sb updatesThis sequence is important as it ensures that, after this point, there is no sbupdate that might be journaled so it is safe to update the sb outside thejournal. (To avoid race discussed in 2d01ddc86606)Also, we don't need a similar check in ext4_grp_locked_error since it is onlycalled from mballoc and AFAICT it would be always valid to schedule work here.

At the lowest level, the atmel_serial driver is usingserial_mctrl_gpio lib to enable/disable the corresponding IRQsaccordingly. The warning emitted by CONFIG_DEBUG_ATOMIC_SLEEP is due todisable_irq (called in mctrl_gpio_disable_ms) being possibly called insome atomic context (some tty drivers perform modem lines configurationin regions protected by port lock).Split mctrl_gpio_disable_ms into two differents APIs, a non-blocking oneand a blocking one. Replace mctrl_gpio_disable_ms calls with therelevant version depending on whether the call is protected by some portlock.

CVE-2025-38336 Severity: Moderate CVSS3 score: 4.1

Description: In the Linux kernel, the following vulnerability has been resolved:ata: pata_via: Force PIO for ATAPI devices on VT6415/VT6330The controller has a hardware bug that can hard hang the system whendoing ATAPI DMAs without any trace of what happened. Depending on thedevice attached, it can also prevent the system from booting.In this case, the system hangs when reading the ATIP from optical mediawith cdrecord -vvv -atip on an _NEC DVD_RW ND-4571A 1-01 and anOptiarc DVD RW AD-7200A 1.06 attached to an ASRock 990FX Extreme 4,running at UDMA/33.The issue can be reproduced by running the same command with a cygwinbuild of cdrecord on WinXP, although it requires more attempts to causeit. The hang in that case is also resolved by forcing PIO. It doesn'tappear that VIA has produced any drivers for that OS, thus no knownworkaround exists.HDDs attached to the controller do not suffer from any DMA issues.

CVE-2025-53906 Severity: Moderate CVSS3 score: 4.1

Description: Vim is an open source, command line text editor. Prior to version 9.1.1551, a path traversal issue in Vim's zip.vim plugin can allow overwriting of arbitrary files when opening specially crafted zip archives. Impact is low because this exploit requires direct user interaction. However, successfully exploitation can lead to overwriting sensitive files or placing executable code in privileged locations, depending on the permissions of the process editing the archive. The victim must edit such a file using Vim which will reveal the filename and the file content, a careful user may suspect some strange things going on. Successful exploitation could results in the ability to execute arbitrary commands on the underlying operating system. Version 9.1.1551 contains a patch for the vulnerability.

CVE-2025-68742 Severity: Moderate CVSS3 score: 4.1

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix invalid prog->stats access when update_effective_progs failsSyzkaller triggers an invalid memory access issue following faultinjection in update_effective_progs. The issue can be described asfollows:__cgroup_bpf_detach update_effective_progs compute_effective_progs bpf_prog_array_alloc <-- fault inject purge_effective_progs /* change to dummy_bpf_prog */ array->items[index] = &dummy_bpf_prog.prog---softirq start---__do_softirq ... __cgroup_bpf_run_filter_skb __bpf_prog_run_save_cb bpf_prog_run stats = this_cpu_ptr(prog->stats) /* invalid memory access */ flags = u64_stats_update_begin_irqsave(&stats->syncp)---softirq end--- static_branch_dec(&cgroup_bpf_enabled_key[atype])The reason is that fault injection caused update_effective_progs to failand then changed the original prog into dummy_bpf_prog.prog inpurge_effective_progs. Then a softirq came, and accessing the members ofdummy_bpf_prog.prog in the softirq triggers invalid mem access.To fix it, skip updating stats when stats is NULL.

CVE-2025-71079 Severity: Moderate CVSS3 score: 4.1

Description: In the Linux kernel, the following vulnerability has been resolved:net: nfc: fix deadlock between nfc_unregister_device and rfkill_fop_writeA deadlock can occur between nfc_unregister_device() and rfkill_fop_write()due to lock ordering inversion between device_lock and rfkill_global_mutex.The problematic lock order is:Thread A (rfkill_fop_write): rfkill_fop_write() mutex_lock(&rfkill_global_mutex) rfkill_set_block() nfc_rfkill_set_block() nfc_dev_down() device_lock(&dev->dev) <- waits for device_lockThread B (nfc_unregister_device): nfc_unregister_device() device_lock(&dev->dev) rfkill_unregister() mutex_lock(&rfkill_global_mutex) <- waits for rfkill_global_mutexThis creates a classic ABBA deadlock scenario.Fix this by moving rfkill_unregister() and rfkill_destroy() outside thedevice_lock critical section. Store the rfkill pointer in a local variablebefore releasing the lock, then call rfkill_unregister() after releasingdevice_lock.This change is safe because rfkill_fop_write() holds rfkill_global_mutexwhile calling the rfkill callbacks, and rfkill_unregister() also acquiresrfkill_global_mutex before cleanup. Therefore, rfkill_unregister() willwait for any ongoing callback to complete before proceeding, anddevice_del() is only called after rfkill_unregister() returns, preventingany use-after-free.The similar lock ordering in nfc_register_device() (device_lock ->rfkill_global_mutex via rfkill_register) is safe because duringregistration the device is not yet in rfkill_list, so no concurrentrfkill operations can occur on this device.

CVE-2026-23361 Severity: Moderate CVSS3 score: 4.1

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: dwc: ep: Flush MSI-X write before unmapping its ATU entryEndpoint drivers use dw_pcie_ep_raise_msix_irq() to raise an MSI-Xinterrupt to the host using a writel(), which generates a PCI posted writetransaction. There's no completion for posted writes, so the writel() mayreturn before the PCI write completes. dw_pcie_ep_raise_msix_irq() alsounmaps the outbound ATU entry used for the PCI write, so the write raceswith the unmap.If the PCI write loses the race with the ATU unmap, the write may corrupthost memory or cause IOMMU errors, e.g., these when running fio with alarger queue depth against nvmet-pci-epf: arm-smmu-v3 fc900000.iommu: 0x0000010000000010 arm-smmu-v3 fc900000.iommu: 0x0000020000000000 arm-smmu-v3 fc900000.iommu: 0x000000090000f040 arm-smmu-v3 fc900000.iommu: 0x0000000000000000 arm-smmu-v3 fc900000.iommu: event: F_TRANSLATION client: 0000:01:00.0 sid: 0x100 ssid: 0x0 iova: 0x90000f040 ipa: 0x0 arm-smmu-v3 fc900000.iommu: unpriv data write s1 "Input address caused fault" stag: 0x0Flush the write by performing a readl() of the same address to ensure thatthe write has reached the destination before the ATU entry is unmapped.The same problem was solved for dw_pcie_ep_raise_msi_irq() in commit8719c64e76bf ("PCI: dwc: ep: Cache MSI outbound iATU mapping"), but thereit was solved by dedicating an outbound iATU only for MSI. We can't do thesame for MSI-X because each vector can have a different msg_addr and themsg_addr may be changed while the vector is masked.[bhelgaas: commit log]

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: taprio: extend minimum interval restriction to entire cycle tooIt is possible for syzbot to side-step the restriction imposed by theblamed commit in the Fixes: tag, because the taprio UAPI permits acycle-time different from (and potentially shorter than) the sum ofentry intervals.We need one more restriction, which is that the cycle time itself mustbe larger than N * ETH_ZLEN bit times, where N is the number of scheduleentries. This restriction needs to apply regardless of whether the cycletime came from the user or was the implicit, auto-calculated value, sowe move the existing "cycle == 0" check outside the "if "(!new->cycle_time)"branch. This way covers both conditions and scenarios.Add a selftest which illustrates the issue triggered by syzbot.

CVE-2022-50476 Severity: Moderate CVSS3 score: 3.7

Description: In the Linux kernel, the following vulnerability has been resolved:ntb_netdev: Use dev_kfree_skb_any() in interrupt contextTX/RX callback handlers (ntb_netdev_tx_handler(),ntb_netdev_rx_handler()) can be called in interruptcontext via the DMA framework when the respectiveDMA operations have completed. As such, any callsby these routines to free skb's, should use theinterrupt context safe dev_kfree_skb_any() function.Previously, these callback handlers would call theinterrupt unsafe version of dev_kfree_skb(). This hasnot presented an issue on Intel IOAT DMA engines asthat driver utilizes tasklets rather than a hardinterrupt handler, like the AMD PTDMA DMA driver.On AMD systems, a kernel WARNING message isencountered, which is being issued fromskb_release_head_state() due to in_hardirq()being true.Besides the user visible WARNING from the kernel,the other symptom of this bug was that TCP/IP performanceacross the ntb_netdev interface was very poor, i.e.approximately an order of magnitude below what wasexpected. With the repair to use dev_kfree_skb_any(),kernel WARNINGs from skb_release_head_state() ceasedand TCP/IP performance, as measured by iperf, was onpar with expected results, approximately 20 Gb/s onAMD Milan based server. Note that this performanceis comparable with Intel based servers.

CVE-2025-38067 Severity: Moderate CVSS3 score: 3.6

Description: In the Linux kernel, the following vulnerability has been resolved:rseq: Fix segfault on registration when rseq_cs is non-zeroThe rseq_cs field is documented as being set to 0 by user-space prior toregistration, however this is not currently enforced by the kernel. Thiscan result in a segfault on return to user-space if the value stored inthe rseq_cs field doesn't point to a valid struct rseq_cs.The correct solution to this would be to fail the rseq registration whenthe rseq_cs field is non-zero. However, some older versions of glibcwill reuse the rseq area of previous threads without clearing therseq_cs field and will also terminate the process if the rseqregistration fails in a secondary thread. This wasn't caught in testingbecause in this case the leftover rseq_cs does point to a valid structrseq_cs.What we can do is clear the rseq_cs field on registration when it'snon-zero which will prevent segfaults on registration and won't breakthe glibc versions that reuse rseq areas on thread creation.

Description: In the Linux kernel, the following vulnerability has been resolved:x86/fred: Fix system hang during S4 resume with FRED enabledUpon a wakeup from S4, the restore kernel starts and initializes theFRED MSRs as needed from its perspective. It then loads a hibernationimage, including the image kernel, and attempts to load image pagesdirectly into their original page frames used before hibernation unlessthose frames are currently in use. Once all pages are moved to theiroriginal locations, it jumps to a "trampoline" page in the image kernel.At this point, the image kernel takes control, but the FRED MSRs stillcontain values set by the restore kernel, which may differ from thoseset by the image kernel before hibernation. Therefore, the image kernelmust ensure the FRED MSRs have the same values as before hibernation.Since these values depend only on the location of the kernel text anddata, they can be recomputed from scratch.

Description: In the Linux kernel, the following vulnerability has been resolved:perf trace: Really free the evsel->priv areaIn 3cb4d5e00e037c70 ("perf trace: Free syscall tp fields inevsel->priv") it only was freeing if strcmp(evsel->tp_format->system,"syscalls") returned zero, while the corresponding initialization ofevsel->priv was being performed if it was _not_ zero, i.e. if the tpsystem wasn't 'syscalls'.Just stop looking for that and free it if evsel->priv was set, whichshould be equivalent.Also use the pre-existing evsel_trace__delete() function.This resolves these leaks, detected with: $ make EXTRA_CFLAGS="-fsanitize=address" BUILD_BPF_SKEL=1 CORESIGHT=1 O=/tmp/build/perf-tools-next -C tools/perf install-bin ================================================================= ==481565==ERROR: LeakSanitizer: detected memory leaks Direct leak of 40 byte(s) in 1 object(s) allocated from: #0 0x7f7343cba097 in calloc (/lib64/libasan.so.8+0xba097) #1 0x987966 in zalloc (/home/acme/bin/perf+0x987966) #2 0x52f9b9 in evsel_trace__new /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:307 #3 0x52f9b9 in evsel__syscall_tp /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:333 #4 0x52f9b9 in evsel__init_raw_syscall_tp /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:458 #5 0x52f9b9 in perf_evsel__raw_syscall_newtp /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:480 #6 0x540e8b in trace__add_syscall_newtp /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:3212 #7 0x540e8b in trace__run /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:3891 #8 0x540e8b in cmd_trace /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:5156 #9 0x5ef262 in run_builtin /home/acme/git/perf-tools-next/tools/perf/perf.c:323 #10 0x4196da in handle_internal_command /home/acme/git/perf-tools-next/tools/perf/perf.c:377 #11 0x4196da in run_argv /home/acme/git/perf-tools-next/tools/perf/perf.c:421 #12 0x4196da in main /home/acme/git/perf-tools-next/tools/perf/perf.c:537 #13 0x7f7342c4a50f in __libc_start_call_main (/lib64/libc.so.6+0x2750f) Direct leak of 40 byte(s) in 1 object(s) allocated from: #0 0x7f7343cba097 in calloc (/lib64/libasan.so.8+0xba097) #1 0x987966 in zalloc (/home/acme/bin/perf+0x987966) #2 0x52f9b9 in evsel_trace__new /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:307 #3 0x52f9b9 in evsel__syscall_tp /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:333 #4 0x52f9b9 in evsel__init_raw_syscall_tp /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:458 #5 0x52f9b9 in perf_evsel__raw_syscall_newtp /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:480 #6 0x540dd1 in trace__add_syscall_newtp /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:3205 #7 0x540dd1 in trace__run /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:3891 #8 0x540dd1 in cmd_trace /home/acme/git/perf-tools-next/tools/perf/builtin-trace.c:5156 #9 0x5ef262 in run_builtin /home/acme/git/perf-tools-next/tools/perf/perf.c:323 #10 0x4196da in handle_internal_command /home/acme/git/perf-tools-next/tools/perf/perf.c:377 #11 0x4196da in run_argv /home/acme/git/perf-tools-next/tools/perf/perf.c:421 #12 0x4196da in main /home/acme/git/perf-tools-next/tools/perf/perf.c:537 #13 0x7f7342c4a50f in __libc_start_call_main (/lib64/libc.so.6+0x2750f) SUMMARY: AddressSanitizer: 80 byte(s) leaked in 2 allocation(s).

Description: In the Linux kernel, the following vulnerability has been resolved:drm/i915/gt: Reset queue_priority_hint on parkingOriginally, with strict in order execution, we could complete executiononly when the queue was empty. Preempt-to-busy allows replacement of anactive request that may complete before the preemption is processed byHW. If that happens, the request is retired from the queue, but thequeue_priority_hint remains set, preventing direct submission untilafter the next CS interrupt is processed.This preempt-to-busy race can be triggered by the heartbeat, which willalso act as the power-management barrier and upon completion allow us toidle the HW. We may process the completion of the heartbeat, and beginparking the engine before the CS event that restores thequeue_priority_hint, causing us to fail the assertion that it is MIN.<3>[ 166.210729] __engine_park:283 GEM_BUG_ON(engine->sched_engine->queue_priority_hint != (-((int)(~0U >> 1)) - 1))<0>[ 166.210781] Dumping ftrace buffer:<0>[ 166.210795] ---------------------------------...<0>[ 167.302811] drm_fdin-1097 2..s1. 165741070us : trace_ports: 0000:00:02.0 rcs0: promote { ccid:20 1217:2 prio 0 }<0>[ 167.302861] drm_fdin-1097 2d.s2. 165741072us : execlists_submission_tasklet: 0000:00:02.0 rcs0: preempting last=1217:2, prio=0, hint=2147483646<0>[ 167.302928] drm_fdin-1097 2d.s2. 165741072us : __i915_request_unsubmit: 0000:00:02.0 rcs0: fence 1217:2, current 0<0>[ 167.302992] drm_fdin-1097 2d.s2. 165741073us : __i915_request_submit: 0000:00:02.0 rcs0: fence 3:4660, current 4659<0>[ 167.303044] drm_fdin-1097 2d.s1. 165741076us : execlists_submission_tasklet: 0000:00:02.0 rcs0: context:3 schedule-in, ccid:40<0>[ 167.303095] drm_fdin-1097 2d.s1. 165741077us : trace_ports: 0000:00:02.0 rcs0: submit { ccid:40 3:4660* prio 2147483646 }<0>[ 167.303159] kworker/-89 11..... 165741139us : i915_request_retire.part.0: 0000:00:02.0 rcs0: fence c90:2, current 2<0>[ 167.303208] kworker/-89 11..... 165741148us : __intel_context_do_unpin: 0000:00:02.0 rcs0: context:c90 unpin<0>[ 167.303272] kworker/-89 11..... 165741159us : i915_request_retire.part.0: 0000:00:02.0 rcs0: fence 1217:2, current 2<0>[ 167.303321] kworker/-89 11..... 165741166us : __intel_context_do_unpin: 0000:00:02.0 rcs0: context:1217 unpin<0>[ 167.303384] kworker/-89 11..... 165741170us : i915_request_retire.part.0: 0000:00:02.0 rcs0: fence 3:4660, current 4660<0>[ 167.303434] kworker/-89 11d..1. 165741172us : __intel_context_retire: 0000:00:02.0 rcs0: context:1216 retire runtime: { total:56028ns, avg:56028ns }<0>[ 167.303484] kworker/-89 11..... 165741198us : __engine_park: 0000:00:02.0 rcs0: parked<0>[ 167.303534] -0 5d.H3. 165741207us : execlists_irq_handler: 0000:00:02.0 rcs0: semaphore yield: 00000040<0>[ 167.303583] kworker/-89 11..... 165741397us : __intel_context_retire: 0000:00:02.0 rcs0: context:1217 retire runtime: { total:325575ns, avg:0ns }<0>[ 167.303756] kworker/-89 11..... 165741777us : __intel_context_retire: 0000:00:02.0 rcs0: context:c90 retire runtime: { total:0ns, avg:0ns }<0>[ 167.303806] kworker/-89 11..... 165742017us : __engine_park: __engine_park:283 GEM_BUG_ON(engine->sched_engine->queue_priority_hint != (-((int)(~0U >> 1)) - 1))<0>[ 167.303811] ---------------------------------<4>[ 167.304722] ------------[ cut here ]------------<2>[ 167.304725] kernel BUG at drivers/gpu/drm/i915/gt/intel_engine_pm.c:283!<4>[ 167.304731] invalid opcode: 0000 [#1] PREEMPT SMP NOPTI<4>[ 167.304734] CPU: 11 PID: 89 Comm: kworker/11:1 Tainted: G W 6.8.0-rc2-CI_DRM_14193-gc655e0fd2804+ #1<4>[ 167.304736] Hardware name: Intel Corporation Rocket Lake Client Platform/RocketLake S UDIMM 6L RVP, BIOS RKLSFWI1.R00.3173.A03.2204210138 04/21/2022<4>[ 167.304738] Workqueue: i915-unordered retire_work_handler [i915]<4>[ 16---truncated---

This thread holds the clkprepare_lock, and is trying to runtime PM resume a device, when it findsthat the device is in the process of resuming so the thread schedule()saway waiting for the device to finish resuming before continuing. Thesecond thread is runtime PM resuming the same device, but the runtimeresume callback is calling clk_prepare(), trying to grab theprepare_lock waiting on the first thread.This is a classic ABBA deadlock. To properly fix the deadlock, we mustnever runtime PM resume or suspend a device with the clk prepare_lockheld. Actually doing that is near impossible today because the globalprepare_lock would have to be dropped in the middle of the tree, thedevice runtime PM resumed/suspended, and then the prepare_lock grabbedagain to ensure consistency of the clk tree topology. If anythingchanges with the clk tree in the meantime, we've lost and will need tostart the operation all over again.Luckily, most of the time we're simply incrementing or decrementing theruntime PM count on an active device, so we don't have the chance toschedule away with the prepare_lock held. Let's fix this immediateproblem that can be---truncated---

CVE-2024-39490 Severity: Moderate CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:ipv6: sr: fix missing sk_buff release in seg6_input_coreThe seg6_input() function is responsible for adding the SRH into apacket, delegating the operation to the seg6_input_core(). This functionuses the skb_cow_head() to ensure that there is sufficient headroom inthe sk_buff for accommodating the link-layer header.In the event that the skb_cow_header() function fails, theseg6_input_core() catches the error but it does not release the sk_buff,which will result in a memory leak.This issue was introduced in commit af3b5158b89d ("ipv6: sr: fix BUG dueto headroom too small after SRH push") and persists even after commit7a3f5b0de364 ("netfilter: add netfilter hooks to SRv6 data plane"),where the entire seg6_input() code was refactored to deal with netfilterhooks.The proposed patch addresses the identified memory leak by requiring theseg6_input_core() function to release the sk_buff in the event thatskb_cow_head() fails.

Description: In the Linux kernel, the following vulnerability has been resolved:xfs: don't walk off the end of a directory data blockThis adds sanity checks for xfs_dir2_data_unused and xfs_dir2_data_entryto make sure don't stray beyond valid memory region. Before patching, theloop simply checks that the start offset of the dup and dep is within therange. So in a crafted image, if last entry is xfs_dir2_data_unused, wecan change dup->length to dup->length-1 and leave 1 byte of space. In thenext traversal, this space will be considered as dup or dep. We mayencounter an out of bound read when accessing the fixed members.In the patch, we make sure that the remaining bytes large enough to holdan unused entry before accessing xfs_dir2_data_unused andxfs_dir2_data_unused is XFS_DIR2_DATA_ALIGN byte aligned. We also makesure that the remaining bytes large enough to hold a dirent with asingle-byte name before accessing xfs_dir2_data_entry.

WARN_ON_ONCE(msk->pm.add_addr_accepted == 0)... before decrementing the add_addr_accepted counter helped to find abug when running the "remove single subflow" subtest from themptcp_join.sh selftest.Removing a 'subflow' endpoint will first trigger a RM_ADDR, then thesubflow closure. Before this patch, and upon the reception of theRM_ADDR, the other peer will then try to decrement thisadd_addr_accepted. That's not correct because the attached subflows havenot been created upon the reception of an ADD_ADDR.A way to solve that is to decrement the counter only if the attachedsubflow was an MP_JOIN to a remote id that was not 0, and initiated bythe host receiving the RM_ADDR.

Since the vPMU is requested, but not setup, kvm_arm_pmu_v3_enable() fails in kvm_arch_vcpu_run_pid_change(). As a result, KVM_RUN returns after enabling the timer, but before incrementing 'userspace_irqchip_in_use': kvm_arch_vcpu_run_pid_change() ret = kvm_arm_pmu_v3_enable() if (!vcpu->arch.pmu.created) return -EINVAL; if (ret) return ret; [...] if (!irqchip_in_kernel(kvm)) static_branch_inc(&userspace_irqchip_in_use); - Userspace ignores the error and issues KVM_ARM_VCPU_INIT again. Since the timer is already enabled, control moves through the following flow, ultimately hitting the WARN_ON(): kvm_timer_vcpu_reset() if (timer->enabled) kvm_timer_update_irq() if (!userspace_irqchip()) ret = kvm_vgic_inject_irq() ret = vgic_lazy_init() if (unlikely(!vgic_initialized(kvm))) if (kvm->arch.vgic.vgic_model != KVM_DEV_TYPE_ARM_VGIC_V2) return -EBUSY; WARN_ON(ret);Theoretically, since userspace_irqchip_in_use's functionality can besimply replaced by '!irqchip_in_kernel()', get rid of the static keyto avoid the mismanagement, which also helps with the syzbot issue.

CVE-2024-53198 Severity: Moderate CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:xen: Fix the issue of resource not being properly released in xenbus_dev_probe()This patch fixes an issue in the function xenbus_dev_probe(). In thexenbus_dev_probe() function, within the if (err) branch at line 313, theprogram incorrectly returns err directly without releasing the resourcesallocated by err = drv->probe(dev, id). As the return value is non-zero,the upper layers assume the processing logic has failed. However, the probeoperation was performed earlier without a corresponding remove operation.Since the probe actually allocates resources, failing to perform the removeoperation could lead to problems.To fix this issue, we followed the resource release logic of thexenbus_dev_remove() function by adding a new block fail_remove before thefail_put block. After entering the branch if (err) at line 313, thefunction will use a goto statement to jump to the fail_remove block,ensuring that the previously acquired resources are correctly released,thus preventing the reference count leak.This bug was identified by an experimental static analysis tool developedby our team. The tool specializes in analyzing reference count operationsand detecting potential issues where resources are not properly managed.In this case, the tool flagged the missing release operation as apotential problem, which led to the development of this patch.

Unregistering the slaveinterfaces is unnecessary and unhelpful. Instead, after the slaves havestopped being uppers of the DSA master, we can now reset to NULL themaster->dsa_ptr pointer, which will make DSA start ignoring all futurenotifier events on the master.

In order to forward wakeupsmc socket waitqueue after fallback, kernel will setsclcsk->sk_user_data to origin smc socket insmc_fback_replace_callbacks().Later, in shutdown syscall, kernel will callssk_psock_get(), which treats the clcsk->sk_user_dataas psock type, triggering the refcnt warning.So, the root cause is that smc and psock, both will usesk_user_data field. So they will mismatch this fieldeasily.This patch solves it by using another bit(defined asSK_USER_DATA_PSOCK) in PTRMASK, to mark whethersk_user_data points to a psock object or not.This patch depends on a PTRMASK introduced in commit f1ff5ce2cd5e("net, sk_msg: Clear sk_user_data pointer on clone if tagged").For there will possibly be more flags in the sk_user_data field,this patch also refactor sk_user_data flags code to be more genericto improve its maintainability.

Description: In the Linux kernel, the following vulnerability has been resolved:tun: Fix memory leak for detached NAPI queue.syzkaller reported [0] memory leaks of sk and skb related to the TUNdevice with no repro, but we can reproduce it easily with: struct ifreq ifr = {} int fd_tun, fd_tmp; char buf[4] = {}; fd_tun = openat(AT_FDCWD, "/dev/net/tun", O_WRONLY, 0); ifr.ifr_flags = IFF_TUN | IFF_NAPI | IFF_MULTI_QUEUE; ioctl(fd_tun, TUNSETIFF, &ifr); ifr.ifr_flags = IFF_DETACH_QUEUE; ioctl(fd_tun, TUNSETQUEUE, &ifr); fd_tmp = socket(AF_PACKET, SOCK_PACKET, 0); ifr.ifr_flags = IFF_UP; ioctl(fd_tmp, SIOCSIFFLAGS, &ifr); write(fd_tun, buf, sizeof(buf)); close(fd_tun);If we enable NAPI and multi-queue on a TUN device, we can put skb intotfile->sk.sk_write_queue after the queue is detached. We should preventit by checking tfile->detached before queuing skb.Note this must be done under tfile->sk.sk_write_queue.lock because write()and ioctl(IFF_DETACH_QUEUE) can run concurrently. Otherwise, there wouldbe a small race window: write() ioctl(IFF_DETACH_QUEUE) `- tun_get_user `- __tun_detach |- if (tfile->detached) |- tun_disable_queue | `-> false | `- tfile->detached = tun | `- tun_queue_purge |- spin_lock_bh(&queue->lock) `- __skb_queue_tail(queue, skb)Another solution is to call tun_queue_purge() when closing andreattaching the detached queue, but it could paper over anotherproblems.

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: fix WARNING in mark_buffer_dirty due to discarded buffer reuseA syzbot stress test using a corrupted disk image reported thatmark_buffer_dirty() called from __nilfs_mark_inode_dirty() ornilfs_palloc_commit_alloc_entry() may output a kernel warning, and canpanic if the kernel is booted with panic_on_warn.This is because nilfs2 keeps buffer pointers in local structures for somemetadata and reuses them, but such buffers may be forcibly discarded bynilfs_clear_dirty_page() in some critical situations.This issue is reported to appear after commit 28a65b49eb53 ("nilfs2: donot write dirty data after degenerating to read-only"), but the issue haspotentially existed before.Fix this issue by checking the uptodate flag when attempting to reuse aninternally held buffer, and reloading the metadata instead of reusing thebuffer if the flag was lost.

CVE-2024-26837 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:net: bridge: switchdev: Skip MDB replays of deferred events on offloadBefore this change, generation of the list of MDB events to replaywould race against the creation of new group memberships, either fromthe IGMP/MLD snooping logic or from user configuration.While new memberships are immediately visible to walkers ofbr->mdb_list, the notification of their existence to switchdev eventsubscribers is deferred until a later point in time. So if a replaylist was generated during a time that overlapped with such a window,it would also contain a replay of the not-yet-delivered event.The driver would thus receive two copies of what the bridge internallyconsidered to be one single event. On destruction of the bridge, onlya single membership deletion event was therefore sent. As aconsequence of this, drivers which reference count memberships (atleast DSA), would be left with orphan groups in their hardwaredatabase when the bridge was destroyed.This is only an issue when replaying additions. While deletion eventsmay still be pending on the deferred queue, they will already havebeen removed from br->mdb_list, so no duplicates can be generated inthat scenario.To a user this meant that old group memberships, from a bridge inwhich a port was previously attached, could be reanimated (inhardware) when the port joined a new bridge, without the new bridge'sknowledge.For example, on an mv88e6xxx system, create a snooping bridge andimmediately add a port to it: root@infix-06-0b-00:~$ ip link add dev br0 up type bridge mcast_snooping 1 && \ > ip link set dev x3 up master br0And then destroy the bridge: root@infix-06-0b-00:~$ ip link del dev br0 root@infix-06-0b-00:~$ mvls atu ADDRESS FID STATE Q F 0 1 2 3 4 5 6 7 8 9 a DEV:0 Marvell 88E6393X 33:33:00:00:00:6a 1 static - - 0 . . . . . . . . . . 33:33:ff:87:e4:3f 1 static - - 0 . . . . . . . . . . ff:ff:ff:ff:ff:ff 1 static - - 0 1 2 3 4 5 6 7 8 9 a root@infix-06-0b-00:~$The two IPv6 groups remain in the hardware database because theport (x3) is notified of the host's membership twice: once via theoriginal event and once via a replay. Since only a single deletenotification is sent, the count remains at 1 when the bridge isdestroyed.Then add the same port (or another port belonging to the same hardwaredomain) to a new bridge, this time with snooping disabled: root@infix-06-0b-00:~$ ip link add dev br1 up type bridge mcast_snooping 0 && \ > ip link set dev x3 up master br1All multicast, including the two IPv6 groups from br0, should now beflooded, according to the policy of br1. But instead the oldmemberships are still active in the hardware database, causing theswitch to only forward traffic to those groups towards the CPU (port0).Eliminate the race in two steps:1. Grab the write-side lock of the MDB while generating the replay list.This prevents new memberships from showing up while we are generatingthe replay list. But it leaves the scenario in which a deferred eventwas already generated, but not delivered, before we grabbed thelock. Therefore:2. Make sure that no deferred version of a replay event is already enqueued to the switchdev deferred queue, before adding it to the replay list, when replaying additions.

CVE-2024-49895 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amd/display: Fix index out of bounds in DCN30 degamma hardware format translationThis commit addresses a potential index out of bounds issue in the`cm3_helper_translate_curve_to_degamma_hw_format` function in the DCN30color management module. The issue could occur when the index 'i'exceeds the number of transfer function points (TRANSFER_FUNC_POINTS).The fix adds a check to ensure 'i' is within bounds before accessing thetransfer function points. If 'i' is out of bounds, the function returnsfalse to indicate an error.Reported by smatch:drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:338 cm3_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.red' 1025 <= s32maxdrivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:339 cm3_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.green' 1025 <= s32maxdrivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:340 cm3_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.blue' 1025 <= s32max

CVE-2024-53079 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:mm/thp: fix deferred split unqueue naming and lockingRecent changes are putting more pressure on THP deferred split queues:under load revealing long-standing races, causing list_del corruptions,"Bad page state"s and worse (I keep BUGs in both of those, so usuallydon't get to see how badly they end up without). The relevant recentchanges being 6.8's mTHP, 6.10's mTHP swapout, and 6.12's mTHP swapin,improved swap allocation, and underused THP splitting.Before fixing locking: rename misleading folio_undo_large_rmappable(),which does not undo large_rmappable, to folio_unqueue_deferred_split(),which is what it does. But that and its out-of-line __callee are mminternals of very limited usability: add comment and WARN_ON_ONCEs tocheck usage; and return a bool to say if a deferred split was unqueued,which can then be used in WARN_ON_ONCEs around safety checks (sparingcallers the arcane conditionals in __folio_unqueue_deferred_split()).Just omit the folio_unqueue_deferred_split() from free_unref_folios(), allof whose callers now call it beforehand (and if any forget then bad_page()will tell) - except for its caller put_pages_list(), which itself nolonger has any callers (and will be deleted separately).Swapout: mem_cgroup_swapout() has been resetting folio->memcg_data 0without checking and unqueueing a THP folio from deferred split list;which is unfortunate, since the split_queue_lock depends on the memcg(when memcg is enabled); so swapout has been unqueueing such THPs later,when freeing the folio, using the pgdat's lock instead: potentiallycorrupting the memcg's list. __remove_mapping() has frozen refcount to 0here, so no problem with calling folio_unqueue_deferred_split() beforeresetting memcg_data.That goes back to 5.4 commit 87eaceb3faa5 ("mm: thp: make deferred splitshrinker memcg aware"): which included a check on swapcache before addingto deferred queue, but no check on deferred queue before adding THP toswapcache. That worked fine with the usual sequence of events in reclaim(though there were a couple of rare ways in which a THP on deferred queuecould have been swapped out), but 6.12 commit dafff3f4c850 ("mm: splitunderused THPs") avoids splitting underused THPs in reclaim, which makesswapcache THPs on deferred queue commonplace.Keep the check on swapcache before adding to deferred queue? Yes: it isno longer essential, but preserves the existing behaviour, and is likelyto be a worthwhile optimization (vmstat showed much more traffic on thequeue under swapping load if the check was removed); update its comment.Memcg-v1 move (deprecated): mem_cgroup_move_account() has been changingfolio->memcg_data without checking and unqueueing a THP folio from thedeferred list, sometimes corrupting "from" memcg's list, like swapout. Refcount is non-zero here, so folio_unqueue_deferred_split() can only beused in a WARN_ON_ONCE to validate the fix, which must be done earlier:mem_cgroup_move_charge_pte_range() first try to split the THP (splittingof course unqueues), or skip it if that fails. Not ideal, but movingcharge has been requested, and khugepaged should repair the THP later:nobody wants new custom unqueueing code just for this deprecated case.The 87eaceb3faa5 commit did have the code to move from one deferred listto another (but was not conscious of its unsafety while refcount non-0);but that was removed by 5.6 commit fac0516b5534 ("mm: thp: don't need caredeferred split queue in memcg charge move path"), which argued that theexistence of a PMD mapping guarantees that the THP cannot be on a deferredlist. As above, false in rare cases, and now commonly false.Backport to 6.11 should be straightforward. Earlier backports must takecare that other _deferred_list fixes and dependencies are included. Thereis not a strong case for backports, but they can fix cornercases.

CVE-2024-57874 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:arm64: ptrace: fix partial SETREGSET for NT_ARM_TAGGED_ADDR_CTRLCurrently tagged_addr_ctrl_set() doesn't initialize the temporary 'ctrl'variable, and a SETREGSET call with a length of zero will leave thisuninitialized. Consequently tagged_addr_ctrl_set() will consume anarbitrary value, potentially leaking up to 64 bits of memory from thekernel stack. The read is limited to a specific slot on the stack, andthe issue does not provide a write mechanism.As set_tagged_addr_ctrl() only accepts values where bits [63:4] zero andrejects other values, a partial SETREGSET attempt will randomly succeedor fail depending on the value of the uninitialized value, and theexposure is significantly limited.Fix this by initializing the temporary value before copying the regsetfrom userspace, as for other regsets (e.g. NT_PRSTATUS, NT_PRFPREG,NT_ARM_SYSTEM_CALL). In the case of a zero-length write, the existingvalue of the tagged address ctrl will be retained.The NT_ARM_TAGGED_ADDR_CTRL regset is only visible in theuser_aarch64_view used by a native AArch64 task to manipulate anothernative AArch64 task. As get_tagged_addr_ctrl() only returns an errorvalue when called for a compat task, tagged_addr_ctrl_get() andtagged_addr_ctrl_set() should never observe an error value fromget_tagged_addr_ctrl(). Add a WARN_ON_ONCE() to both to indicate thatsuch an error would be unexpected, and error handlnig is not missing ineither case.

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: Fail COMEDI_INSNLIST ioctl if n_insns is too largeThe handling of the `COMEDI_INSNLIST` ioctl allocates a kernel buffer tohold the array of `struct comedi_insn`, getting the length from the`n_insns` member of the `struct comedi_insnlist` supplied by the user.The allocation will fail with a WARNING and a stack dump if it is toolarge.Avoid that by failing with an `-EINVAL` error if the supplied `n_insns`value is unreasonable.Define the limit on the `n_insns` value in the `MAX_INSNS` macro. Setthis to the same value as `MAX_SAMPLES` (65536), which is the maximumallowed sum of the values of the member `n` in the array of `structcomedi_insn`, and sensible comedi instructions will have an `n` of atleast 1.

CVE-2025-38623 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: pnv_php: Fix surprise plug detection and recoveryThe existing PowerNV hotplug code did not handle surprise plug eventscorrectly, leading to a complete failure of the hotplug system after deviceremoval and a required reboot to detect new devices.This comes down to two issues: 1) When a device is surprise removed, often the bridge upstream port will cause a PE freeze on the PHB. If this freeze is not cleared, the MSI interrupts from the bridge hotplug notification logic will not be received by the kernel, stalling all plug events on all slots associated with the PE. 2) When a device is removed from a slot, regardless of surprise or programmatic removal, the associated PHB/PE ls left frozen. If this freeze is not cleared via a fundamental reset, skiboot is unable to clear the freeze and cannot retrain / rescan the slot. This also requires a reboot to clear the freeze and redetect the device in the slot.Issue the appropriate unfreeze and rescan commands on hotplug events,and don't oops on hotplug if pci_bus_to_OF_node() returns NULL.[bhelgaas: tidy comments]

CVE-2025-40105 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:vfs: Don't leak disconnected dentries on umountWhen user calls open_by_handle_at() on some inode that is not cached, wewill create disconnected dentry for it. If such dentry is a directory,exportfs_decode_fh_raw() will then try to connect this dentry to thedentry tree through reconnect_path(). It may happen for various reasons(such as corrupted fs or race with rename) that the call tolookup_one_unlocked() in reconnect_one() will fail to find the dentry weare trying to reconnect and instead create a new dentry under theparent. Now this dentry will not be marked as disconnected although theparent still may well be disconnected (at least in case thisinconsistency happened because the fs is corrupted and .. doesn't pointto the real parent directory). This creates inconsistency indisconnected flags but AFAICS it was mostly harmless. At least untilcommit f1ee616214cb ("VFS: don't keep disconnected dentries on d_anon")which removed adding of most disconnected dentries to sb->s_anon list.Thus after this commit cleanup of disconnected dentries implicitelyrelies on the fact that dput() will immediately reclaim such dentries.However when some leaf dentry isn't marked as disconnected, as in thescenario described above, the reclaim doesn't happen and the dentriesare "leaked". Memory reclaim can eventually reclaim them but otherwisethey stay in memory and if umount comes first, we hit infamous "Busyinodes after unmount" bug. Make sure all dentries created under adisconnected parent are marked as disconnected as well.

Description: In the Linux kernel, the following vulnerability has been resolved:xen/events: Return -EEXIST for bound VIRQsChange find_virq() to return -EEXIST when a VIRQ is bound to adifferent CPU than the one passed in. With that, remove the BUG_ON()from bind_virq_to_irq() to propogate the error upwards.Some VIRQs are per-cpu, but others are per-domain or global. Those mustbe bound to CPU0 and can then migrate elsewhere. The lookup forper-domain and global will probably fail when migrated off CPU 0,especially when the current CPU is tracked. This now returns -EEXISTinstead of BUG_ON().A second call to bind a per-domain or global VIRQ is not expected, butmake it non-fatal to avoid trying to look up the irq, since we don'tknow which per_cpu(virq_to_irq) it will be in.

But there are cases where we could avoid revalidation.Consider:1 input -> j2 -> j32 input -> j2 -> j33 input -> j1 -> j2 -> j3Then the second rule does not need to revalidate j2, and, by extension j3,because this was already checked during validation of the first rule.We need to validate it only for rule 3.This is needed because chain loop detection also ensures we do not exceedthe jump stack: Just because we know that j2 is cycle free, its last jumpmight now exceed the allowed stack size. We also need to update allreachable chains with the new largest observed call depth.Care has to be taken to revalidate even if the chain depth won't be anissue: chain validation also ensures that expressions are not called frominvalid base chains. For example, the masquerade expression can only becalled from NAT postrouting base chains.Therefore we also need to keep record of the base chain context (type,hooknum) and revalidate if the chain becomes reachable from a differenthook location.

CVE-2026-23258 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:net: liquidio: Initialize netdev pointer before queue setupIn setup_nic_devices(), the netdev is allocated using alloc_etherdev_mq().However, the pointer to this structure is stored in oct->props[i].netdevonly after the calls to netif_set_real_num_rx_queues() andnetif_set_real_num_tx_queues().If either of these functions fails, setup_nic_devices() returns an errorwithout freeing the allocated netdev. Since oct->props[i].netdev is stillNULL at this point, the cleanup function liquidio_destroy_nic_device()will fail to find and free the netdev, resulting in a memory leak.Fix this by initializing oct->props[i].netdev before calling the queuesetup functions. This ensures that the netdev is properly accessible forcleanup in case of errors.Compile tested only. Issue found using a prototype static analysis tooland code review.

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: qat - fix DMA transfer directionWhen CONFIG_DMA_API_DEBUG is selected, while running the crypto selftest on the QAT crypto algorithms, the function add_dma_entry() reportsa warning similar to the one below, saying that overlapping mappingsare not supported. This occurs in tests where the input and the outputscatter list point to the same buffers (i.e. two different scatter listswhich point to the same chunks of memory).The logic that implements the mapping uses the flag DMA_BIDIRECTIONALfor both the input and the output scatter lists which leads tooverlapped write mappings. These are not supported by the DMA layer.Fix by specifying the correct DMA transfer directions when mappingbuffers. For in-place operations where the input scatter listmatches the output scatter list, buffers are mapped once withDMA_BIDIRECTIONAL, otherwise input buffers are mapped using the flagDMA_TO_DEVICE and output buffers are mapped with DMA_FROM_DEVICE.Overlapping a read mapping with a write mapping is a valid case indma-coherent devices like QAT.The function that frees and unmaps the buffers, qat_alg_free_bufl()has been changed accordingly to the changes to the mapping function.

Consequently, thisissue is causing the following KCSAN splat to occur: BUG: KCSAN: data-race in unix_release_sock / unix_stream_sendmsg write (marked) to 0xffff88867256ddbb of 1 bytes by task 7270 on cpu 28: unix_release_sock (net/unix/af_unix.c:640) unix_release (net/unix/af_unix.c:1050) sock_close (net/socket.c:659 net/socket.c:1421) __fput (fs/file_table.c:422) __fput_sync (fs/file_table.c:508) __se_sys_close (fs/open.c:1559 fs/open.c:1541) __x64_sys_close (fs/open.c:1541) x64_sys_call (arch/x86/entry/syscall_64.c:33) do_syscall_64 (arch/x86/entry/common.c:?) entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:130) read to 0xffff88867256ddbb of 1 bytes by task 989 on cpu 14: unix_stream_sendmsg (net/unix/af_unix.c:2273) __sock_sendmsg (net/socket.c:730 net/socket.c:745) ____sys_sendmsg (net/socket.c:2584) __sys_sendmmsg (net/socket.c:2638 net/socket.c:2724) __x64_sys_sendmmsg (net/socket.c:2753 net/socket.c:2750 net/socket.c:2750) x64_sys_call (arch/x86/entry/syscall_64.c:33) do_syscall_64 (arch/x86/entry/common.c:?) entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:130) value changed: 0x01 -> 0x03The line numbers are related to commit dd5a440a31fa ("Linux 6.9-rc7").Commit e1d09c2c2f57 ("af_unix: Fix data races around sk->sk_shutdown.")addressed a comparable issue in the past regarding sk->sk_shutdown.However, it overlooked resolving this particular data path.This patch only offending unix_stream_sendmsg() function, since theother reads seem to be protected by unix_state_lock() as discussed in

Description: In the Linux kernel, the following vulnerability has been resolved:tcp: avoid too many retransmit packetsIf a TCP socket is using TCP_USER_TIMEOUT, and the other peerretracted its window to zero, tcp_retransmit_timer() canretransmit a packet every two jiffies (2 ms for HZ=1000),for about 4 minutes after TCP_USER_TIMEOUT has 'expired'.The fix is to make sure tcp_rtx_probe0_timed_out() takesicsk->icsk_user_timeout into account.Before blamed commit, the socket would not timeout aftericsk->icsk_user_timeout, but would use standard exponentialbackoff for the retransmits.Also worth noting that before commit e89688e3e978 ("net: tcp:fix unexcepted socket die when snd_wnd is 0"), the issuewould last 2 minutes instead of 4.

Since the bulk of this function happensunder inode->i_lock this causes a significant contention on the lockwhen we remove the watch from the directory as the__fsnotify_update_child_dentry_flags() call from fsnotify_recalc_mask()races with __fsnotify_update_child_dentry_flags() calls from__fsnotify_parent() happening on children. This can lead upto softlockupreports reported by users.Fix the problem by calling fsnotify_update_children_dentry_flags() toset PARENT_WATCHED flags only when parent starts watching children.When parent stops watching children, clear false positive PARENT_WATCHEDflags lazily in __fsnotify_parent() for each accessed child.

CVE-2024-56644 Severity: Low CVSS3 score: 2.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/ipv6: release expired exception dst cached in socketDst objects get leaked in ip6_negative_advice() when this function isexecuted for an expired IPv6 route located in the exception table. Thereare several conditions that must be fulfilled for the leak to occur:* an ICMPv6 packet indicating a change of the MTU for the path is received, resulting in an exception dst being created* a TCP connection that uses the exception dst for routing packets must start timing out so that TCP begins retransmissions* after the exception dst expires, the FIB6 garbage collector must not run before TCP executes ip6_negative_advice() for the expired exception dstWhen TCP executes ip6_negative_advice() for an exception dst that hasexpired and if no other socket holds a reference to the exception dst, therefcount of the exception dst is 2, which corresponds to the incrementmade by dst_init() and the increment made by the TCP socket for which theconnection is timing out. The refcount made by the socket is neverreleased. The refcount of the dst is decremented in sk_dst_reset() butthat decrement is counteracted by a dst_hold() intentionally placed justbefore the sk_dst_reset() in ip6_negative_advice(). Afterip6_negative_advice() has finished, there is no other object tied to thedst. The socket lost its reference stored in sk_dst_cache and the dst isno longer in the exception table. The exception dst becomes a leakedobject.As a result of this dst leak, an unbalanced refcount is reported for theloopback device of a net namespace being destroyed under kernels that donot contain e5f80fcf869a ("ipv6: give an IPv6 dev to blackhole_netdev"):unregister_netdevice: waiting for lo to become free. Usage count = 2Fix the dst leak by removing the dst_hold() in ip6_negative_advice(). Thepatch that introduced the dst_hold() in ip6_negative_advice() was92f1655aa2b22 ("net: fix __dst_negative_advice() race"). But 92f1655aa2b22merely refactored the code with regards to the dst refcount so the issuewas present even before 92f1655aa2b22. The bug was introduced in54c1a859efd9f ("ipv6: Don't drop cache route entry unless timer actuallyexpired.") where the expired cached route is deleted and the sk_dst_cachemember of the socket is set to NULL by calling dst_negative_advice() butthe refcount belonging to the socket is left unbalanced.The IPv4 version - ipv4_negative_advice() - is not affected by this bug.When the TCP connection times out ipv4_negative_advice() merely resets thesk_dst_cache of the socket while decrementing the refcount of theexception dst.

CVE-2025-22021 Severity: Low CVSS3 score: 2.5

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: socket: Lookup orig tuple for IPv6 SNATnf_sk_lookup_slow_v4 does the conntrack lookup for IPv4 packets torestore the original 5-tuple in case of SNAT, to be able to find theright socket (if any). Then socket_match() can correctly check whetherthe socket was transparent.However, the IPv6 counterpart (nf_sk_lookup_slow_v6) lacks thisconntrack lookup, making xt_socket fail to match on the socket when thepacket was SNATed. Add the same logic to nf_sk_lookup_slow_v6.IPv6 SNAT is used in Kubernetes clusters for pod-to-world packets, aspods' addresses are in the fd00::/8 ULA subnet and need to be replacedwith the node's external address. Cilium leverages Envoy to enforce L7policies, and Envoy uses transparent sockets. Cilium inserts an iptablesprerouting rule that matches on `-m socket --transparent` and redirectsthe packets to localhost, but it fails to match SNATed IPv6 packets dueto that missing conntrack lookup.

CVE-2025-39737 Severity: Low CVSS3 score: 2.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm/kmemleak: avoid soft lockup in __kmemleak_do_cleanup()A soft lockup warning was observed on a relative small system x86-64system with 16 GB of memory when running a debug kernel with kmemleakenabled. watchdog: BUG: soft lockup - CPU#8 stuck for 33s! [kworker/8:1:134]The test system was running a workload with hot unplug happening inparallel. Then kemleak decided to disable itself due to its inability toallocate more kmemleak objects. The debug kernel has itsCONFIG_DEBUG_KMEMLEAK_MEM_POOL_SIZE set to 40,000.The soft lockup happened in kmemleak_do_cleanup() when the existingkmemleak objects were being removed and deleted one-by-one in a loop via aworkqueue. In this particular case, there are at least 40,000 objectsthat need to be processed and given the slowness of a debug kernel and thefact that a raw_spinlock has to be acquired and released in__delete_object(), it could take a while to properly handle all theseobjects.As kmemleak has been disabled in this case, the object removal anddeletion process can be further optimized as locking isn't really needed. However, it is probably not worth the effort to optimize for such an edgecase that should rarely happen. So the simple solution is to callcond_resched() at periodic interval in the iteration loop to avoid softlockup.

CVE-2022-48714 Severity: Low CVSS3 score: 2.3

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Use VM_MAP instead of VM_ALLOC for ringbufAfter commit 2fd3fb0be1d1 ("kasan, vmalloc: unpoison VM_ALLOC pagesafter mapping"), non-VM_ALLOC mappings will be marked as accessiblein __get_vm_area_node() when KASAN is enabled. But now the flag forringbuf area is VM_ALLOC, so KASAN will complain out-of-bound accessafter vmap() returns. Because the ringbuf area is created by mappingallocated pages, so use VM_MAP instead.After the change, info in /proc/vmallocinfo also changes from [start]-[end] 24576 ringbuf_map_alloc+0x171/0x290 vmalloc userto [start]-[end] 24576 ringbuf_map_alloc+0x171/0x290 vmap user

CVE-2022-50625 Severity: Low CVSS3 score: 2.3

Description: In the Linux kernel, the following vulnerability has been resolved:serial: amba-pl011: avoid SBSA UART accessing DMACR registerChapter "B Generic UART" in "ARM Server Base System Architecture" [1]documentation describes a generic UART interface. Such generic UARTdoes not support DMA. In current code, sbsa_uart_pops andamba_pl011_pops share the same stop_rx operation, which will invokepl011_dma_rx_stop, leading to an access of the DMACR register. Thiscommit adds a using_rx_dma check in pl011_dma_rx_stop to avoid theaccess to DMACR register for SBSA UARTs which does not support DMA.When the kernel enables DMA engine with "CONFIG_DMA_ENGINE=y", LinuxSBSA PL011 driver will access PL011 DMACR register in some functions.For most real SBSA Pl011 hardware implementations, the DMACR writebehaviour will be ignored. So these DMACR operations will not causeobvious problems. But for some virtual SBSA PL011 hardware, like Xenvirtual SBSA PL011 (vpl011) device, the behaviour might be different.Xen vpl011 emulation will inject a data abort to guest, when guest isaccessing an unimplemented UART register. As Xen VPL011 is SBSAcompatible, it will not implement DMACR register. So when Linux SBSAPL011 driver access DMACR register, it will get an unhandled data abortfault and the application will get a segmentation fault:Unhandled fault at 0xffffffc00944d048Mem abort info: ESR = 0x96000000 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x00: ttbr address size faultData abort info: ISV = 0, ISS = 0x00000000 CM = 0, WnR = 0swapper pgtable: 4k pages, 39-bit VAs, pgdp=0000000020e2e000[ffffffc00944d048] pgd=100000003ffff803, p4d=100000003ffff803, pud=100000003ffff803, pmd=100000003fffa803, pte=006800009c090f13Internal error: ttbr address size fault: 96000000 [#1] PREEMPT SMP...Call trace: pl011_stop_rx+0x70/0x80 tty_port_shutdown+0x7c/0xb4 tty_port_close+0x60/0xcc uart_close+0x34/0x8c tty_release+0x144/0x4c0 __fput+0x78/0x220 ____fput+0x1c/0x30 task_work_run+0x88/0xc0 do_notify_resume+0x8d0/0x123c el0_svc+0xa8/0xc0 el0t_64_sync_handler+0xa4/0x130 el0t_64_sync+0x1a0/0x1a4Code: b9000083 b901f001 794038a0 8b000042 (b9000041)---[ end trace 83dd93df15c3216f ]---note: bootlogd[132] exited with preempt_count 1/etc/rcS.d/S07bootlogd: line 47: 132 Segmentation fault start-stop-daemonThis has been discussed in the Xen community, and we think it should fixthis in Linux.

CVE-2023-53585 Severity: Low CVSS3 score: 2.3

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: reject unhashed sockets in bpf_sk_assignThe semantics for bpf_sk_assign are as follows: sk = some_lookup_func() bpf_sk_assign(skb, sk) bpf_sk_release(sk)That is, the sk is not consumed by bpf_sk_assign. The functiontherefore needs to make sure that sk lives long enough to beconsumed from __inet_lookup_skb. The path through the stack for aTCPv4 packet is roughly: netif_receive_skb_core: takes RCU read lock __netif_receive_skb_core: sch_handle_ingress: tcf_classify: bpf_sk_assign() deliver_ptype_list_skb: deliver_skb: ip_packet_type->func == ip_rcv: ip_rcv_core: ip_rcv_finish_core: dst_input: ip_local_deliver: ip_local_deliver_finish: ip_protocol_deliver_rcu: tcp_v4_rcv: __inet_lookup_skb: skb_steal_sockThe existing helper takes advantage of the fact that everythinghappens in the same RCU critical section: for sockets withSOCK_RCU_FREE set bpf_sk_assign never takes a reference.skb_steal_sock then checks SOCK_RCU_FREE again and does sock_putif necessary.This approach assumes that SOCK_RCU_FREE is never set on a skbetween bpf_sk_assign and skb_steal_sock, but this invariant isviolated by unhashed UDP sockets. A new UDP socket is createdin TCP_CLOSE state but without SOCK_RCU_FREE set. That flag is onlyadded in udp_lib_get_port() which happens when a socket is bound.When bpf_sk_assign was added it wasn't possible to access unhashedUDP sockets from BPF, so this wasn't a problem. This changedin commit 0c48eefae712 ("sock_map: Lift socket state restrictionfor datagram sockets"), but the helper wasn't adjusted accordingly.The following sequence of events will therefore lead to a refcountleak:1. Add socket(AF_INET, SOCK_DGRAM) to a sockmap.2. Pull socket out of sockmap and bpf_sk_assign it. Since SOCK_RCU_FREE is not set we increment the refcount.3. bind() or connect() the socket, setting SOCK_RCU_FREE.4. skb_steal_sock will now set refcounted = false due to SOCK_RCU_FREE.5. tcp_v4_rcv() skips sock_put().Fix the problem by rejecting unhashed sockets in bpf_sk_assign().This matches the behaviour of __inet_lookup_skb which is ultimatelythe goal of bpf_sk_assign().

If no task can bebalanced to dst_cpu we'll try to balance the task to the new_dst_cpuinstead. In this case when the migration disabled task is not on CPU itonly allows to run on its current CPU, load balance will select itscurrent CPU as new_dst_cpu and later triggers the warning above.The new_dst_cpu is chosen from the env->dst_grpmask. Currently itcontains CPUs in sched_group_span() and if we have overlapped groups it'spossible to run into this case. This patch makes env->dst_grpmask ofgroup_balance_mask() which exclude any CPUs from the busiest group andsolve the issue. For balancing in a domain with no overlapped groupsthe behaviour keeps same as before.

CVE-2023-53243 Severity: Moderate CVSS3 score: 0.0

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: add handling for RAID1C23/DUP to btrfs_reduce_alloc_profileCallers of `btrfs_reduce_alloc_profile` expect it to return exactlyone allocation profile flag, and failing to do so may ultimatelyresult in a WARN_ON and remount-ro when allocating new blocks, likethe below transaction abort on 6.1.`btrfs_reduce_alloc_profile` has two ways of determining the profile,first it checks if a conversion balance is currently running anduses the profile we're converting to. If no balance is currentlyrunning, it returns the max-redundancy profile which at least oneblock in the selected block group has.This works by simply checking each known allocation profile bit inredundancy order. However, `btrfs_reduce_alloc_profile` has not beenupdated as new flags have been added - first with the `DUP` profileand later with the RAID1C34 profiles.Because of the way it checks, if we have blocks with differentprofiles and at least one is known, that profile will be selected.However, if none are known we may return a flag set with multipleallocation profiles set.This is currently only possible when a balance from one of the threeunhandled profiles to another of the unhandled profiles is canceledafter allocating at least one block using the new profile.In that case, a transaction abort like the below will occur and thefilesystem will need to be mounted with -o skip_balance to get itmounted rw again (but the balance cannot be resumed without asimilar abort).

Description: In the Linux kernel, the following vulnerability has been resolved:firmware: arm_ffa: Fix FFA device names for logical partitionsEach physical partition can provide multiple services each with UUID.Each such service can be presented as logical partition with a uniquecombination of VM ID and UUID. The number of distinct UUID in a systemwill be less than or equal to the number of logical partitions.However, currently it fails to register more than one logical partitionor service within a physical partition as the device name contains onlyVM ID while both VM ID and UUID are maintained in the partition information.The kernel complains with the below message: | sysfs: cannot create duplicate filename '/devices/arm-ffa-8001' | CPU: 1 PID: 1 Comm: swapper/0 Not tainted 6.3.0-rc7 #8 | Hardware name: FVP Base RevC (DT) | Call trace: | dump_backtrace+0xf8/0x118 | show_stack+0x18/0x24 | dump_stack_lvl+0x50/0x68 | dump_stack+0x18/0x24 | sysfs_create_dir_ns+0xe0/0x13c | kobject_add_internal+0x220/0x3d4 | kobject_add+0x94/0x100 | device_add+0x144/0x5d8 | device_register+0x20/0x30 | ffa_device_register+0x88/0xd8 | ffa_setup_partitions+0x108/0x1b8 | ffa_init+0x2ec/0x3a4 | do_one_initcall+0xcc/0x240 | do_initcall_level+0x8c/0xac | do_initcalls+0x54/0x94 | do_basic_setup+0x1c/0x28 | kernel_init_freeable+0x100/0x16c | kernel_init+0x20/0x1a0 | ret_from_fork+0x10/0x20 | kobject_add_internal failed for arm-ffa-8001 with -EEXIST, don't try to | register things with the same name in the same directory. | arm_ffa arm-ffa: unable to register device arm-ffa-8001 err=-17 | ARM FF-A: ffa_setup_partitions: failed to register partition ID 0x8001By virtue of being random enough to avoid collisions when generated in adistributed system, there is no way to compress UUID keys to the numberof bits required to identify each. We can eliminate '-' in the name butit is not worth eliminating 4 bytes and add unnecessary logic for doingthat. Also v1.0 doesn't provide the UUID of the partitions which makesit hard to use the same for the device name.So to keep it simple, let us alloc an ID using ida_alloc() and append thesame to "arm-ffa" to make up a unique device name. Also stash the id valuein ffa_dev to help freeing the ID later when the device is destroyed.

Description: In the Linux kernel, the following vulnerability has been resolved:start_kernel: Add __no_stack_protector function attributeBack during the discussion ofcommit a9a3ed1eff36 ("x86: Fix early boot crash on gcc-10, third try")we discussed the need for a function attribute to control the omissionof stack protectors on a per-function basis; at the time Clang hadsupport for no_stack_protector but GCC did not. This was fixed ingcc-11. Now that the function attribute is available, let's start usingit.Callers of boot_init_stack_canary need to use this function attributeunless they're compiled with -fno-stack-protector, otherwise the canarystored in the stack slot of the caller will differ upon the call toboot_init_stack_canary. This will lead to a call to __stack_chk_fail()then panic.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: drop unnecessary user-triggerable WARN_ONCE in verifierl logIt's trivial for user to trigger "verifier log line truncated" warning,as verifier has a fixed-sized buffer of 1024 bytes (as of now), and there are atleast two pieces of user-provided information that can be output throughthis buffer, and both can be arbitrarily sized by user: - BTF names; - BTF.ext source code lines strings.Verifier log buffer should be properly sized for typical verifier stateoutput. But it's sort-of expected that this buffer won't be long enoughin some circumstances. So let's drop the check. In any case code willwork correctly, at worst truncating a part of a single line output.

So thereis no correctness issue here, we just want to silence warning.To silence the warning, I added DECL_TAG as one of kinds inbtf_type_nosize() which will cause btf_type_id_size() returningNULL earlier without the warning.

Description: In the Linux kernel, the following vulnerability has been resolved:powerpc/pseries: Rework lppaca_shared_proc() to avoid DEBUG_PREEMPTlppaca_shared_proc() takes a pointer to the lppaca which is typicallyaccessed through get_lppaca(). With DEBUG_PREEMPT enabled, this leadsto checking if preemption is enabled, for example: BUG: using smp_processor_id() in preemptible [00000000] code: grep/10693 caller is lparcfg_data+0x408/0x19a0 CPU: 4 PID: 10693 Comm: grep Not tainted 6.5.0-rc3 #2 Call Trace: dump_stack_lvl+0x154/0x200 (unreliable) check_preemption_disabled+0x214/0x220 lparcfg_data+0x408/0x19a0 ...This isn't actually a problem however, as it does not matter whichlppaca is accessed, the shared proc state will be the same.vcpudispatch_stats_procfs_init() already works around this by disablingpreemption, but the lparcfg code does not, erroring any time/proc/powerpc/lparcfg is accessed with DEBUG_PREEMPT enabled.Instead of disabling preemption on the caller side, reworklppaca_shared_proc() to not take a pointer and instead directly accessthe lppaca, bypassing any potential preemption checks.[mpe: Rework to avoid needing a definition in paca.h and lppaca.h]

Womp womp.Fix the glaring UAPI bug by skipping over all the MMIO emulation incase there is a pending synchronous exception. Note that while userspaceis capable of pending an asynchronous exception (SError, IRQ, or FIQ),it is still safe to retire the MMIO instruction in this case as (1) theyare by definition asynchronous, and (2) KVM relies on hardware supportfor pending/delivering these exceptions instead of the software statemachine for advancing PC.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: f_fs: Remove WARN_ON in functionfs_bindThis commit addresses an issue related to below kernel panic wherepanic_on_warn is enabled. It is caused by the unnecessary use of WARN_ONin functionsfs_bind, which easily leads to the following scenarios.1.adb_write in adbd 2.

The segment list is then DMA'ed bythe FW and the length of the DMA is returned by FW. The driver thencopies this DMA'ed segment list to info->dest_buf.In some cases, this DMA length may exceed the info->dest_buf lengthand cause the above BUG condition. Fix it by capping the copylength to not exceed the length of info->dest_buf. The extraDMA data contains no useful information.This code path is shared for the HWRM_DBG_COREDUMP_LIST and theHWRM_DBG_COREDUMP_RETRIEVE FW commands. The buffering is differentfor these 2 FW commands. To simplify the logic, we need to movethe line to adjust the buffer length for HWRM_DBG_COREDUMP_RETRIEVEup, so that the new check to cap the copy length will work for bothcommands.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/nouveau: Fix WARN_ON in nouveau_fence_context_kill()Nouveau is mostly designed in a way that it's expected that fences onlyever get signaled through nouveau_fence_signal(). However, in at leastone other place, nouveau_fence_done(), can signal fences, too. If thathappens (race) a signaled fence remains in the pending list for a while,until it gets removed by nouveau_fence_update().Should nouveau_fence_context_kill() run in the meantime, this would bea bug because the function would attempt to set an error code on analready signaled fence.Have nouveau_fence_context_kill() check for a fence being signaled.

CVE-2025-39801 Severity: Moderate CVSS3 score: 0.0

Description: In the Linux kernel, the following vulnerability has been resolved:usb: dwc3: Remove WARN_ON for device endpoint command timeoutsThis commit addresses a rarely observed endpoint command timeoutwhich causes kernel panic due to warn when 'panic_on_warn' is enabledand unnecessary call trace prints when 'panic_on_warn' is disabled.It is seen during fast software-controlled connect/disconnect testcases.The following is one such endpoint command timeout that we observed:1. Connect =======->dwc3_thread_interrupt ->dwc3_ep0_interrupt ->configfs_composite_setup ->composite_setup ->usb_ep_queue ->dwc3_gadget_ep0_queue ->__dwc3_gadget_ep0_queue ->__dwc3_ep0_do_control_data ->dwc3_send_gadget_ep_cmd2. Disconnect ==========->dwc3_thread_interrupt ->dwc3_gadget_disconnect_interrupt ->dwc3_ep0_reset_state ->dwc3_ep0_end_control_data ->dwc3_send_gadget_ep_cmdIn the issue scenario, in Exynos platforms, we observed that controltransfers for the previous connect have not yet been completed and endtransfer command sent as a part of the disconnect sequence andprocessing of USB_ENDPOINT_HALT feature request from the host timeout.This maybe an expected scenario since the controller is processing EPcommands sent as a part of the previous connect. It maybe better toremove WARN_ON in all places where device endpoint commands are sent toavoid unnecessary kernel panic due to warn.

CVE-2025-40104 Severity: Moderate CVSS3 score: 0.0

Description: In the Linux kernel, the following vulnerability has been resolved:ixgbevf: fix mailbox API compatibility by negotiating supported featuresThere was backward compatibility in the terms of mailbox API. Variousdrivers from various OSes supporting 10G adapters from Intel portfoliocould easily negotiate mailbox API.This convention has been broken since introducing API 1.4.Commit 0062e7cc955e ("ixgbevf: add VF IPsec offload code") added supportfor IPSec which is specific only for the kernel ixgbe driver. None of therest of the Intel 10G PF/VF drivers supports it. And actually lack ofsupport was not included in the IPSec implementation - there were no suchcode paths. No possibility to negotiate support for the feature wasintroduced along with introduction of the feature itself.Commit 339f28964147 ("ixgbevf: Add support for new mailbox communicationbetween PF and VF") increasing API version to 1.5 did the same - itintroduced code supported specifically by the PF ESX driver. It altered APIversion for the VF driver in the same time not touching the versiondefined for the PF ixgbe driver. It led to additional discrepancies,as the code provided within API 1.6 cannot be supported for Linux ixgbedriver as it causes crashes.The issue was noticed some time ago and mitigated by Jake within the commitd0725312adf5 ("ixgbevf: stop attempting IPSEC offload on Mailbox API 1.5").As a result we have regression for IPsec support and after increasing APIto version 1.6 ixgbevf driver stopped to support ESX MBX.To fix this mess add new mailbox op asking PF driver about supportedfeatures. Basing on a response determine whether to set support for IPSecand ESX-specific enhanced mailbox.New mailbox op, for compatibility purposes, must be added within new APIrevision, as API version of OOT PF & VF drivers is already increased to1.6 and doesn't incorporate features negotiate op.Features negotiation mechanism gives possibility to be extended with newfeatures when needed in the future.

CVE-2026-23463 Severity: Moderate CVSS3 score: 0.0

Description: In the Linux kernel, the following vulnerability has been resolved:soc: fsl: qbman: fix race condition in qman_destroy_fqWhen QMAN_FQ_FLAG_DYNAMIC_FQID is set, there's a race condition betweenfq_table[fq->idx] state and freeing/allocating from the pool andWARN_ON(fq_table[fq->idx]) in qman_create_fq() gets triggered.Indeed, we can have: Thread A Thread B qman_destroy_fq() qman_create_fq() qman_release_fqid() qman_shutdown_fq() gen_pool_free() -- At this point, the fqid is available again -- qman_alloc_fqid() -- so, we can get the just-freed fqid in thread B -- fq->fqid = fqid; fq->idx = fqid * 2; WARN_ON(fq_table[fq->idx]); fq_table[fq->idx] = fq; fq_table[fq->idx] = NULL;And adding some logs between qman_release_fqid() andfq_table[fq->idx] = NULL makes the WARN_ON() trigger a lot more.To prevent that, ensure that fq_table[fq->idx] is set to NULL beforegen_pool_free() is called by using smp_wmb().
