CVE-2026-27820 Severity: Important CVSS3 score: 8.8

Description: zlib is a Ruby interface for the zlib compression/decompression library. Versions 3.0.0 and below, 3.1.0, 3.1.1, 3.2.0 and 3.2.1 contain a buffer overflow vulnerability in the Zlib::GzipReader. The zstream_buffer_ungets function prepends caller-provided bytes ahead of previously produced output but fails to guarantee the backing Ruby string has enough capacity before the memmove shifts the existing data. This can lead to memory corruption when the buffer length exceeds capacity. This issue has been fixed in versions 3.0.1, 3.1.2 and 3.2.3.

CVE-2023-34049 Severity: Important CVSS3 score: 8.4

Description: The Salt-SSH pre-flight option copies the script to the target at a predictable path, which allows an attacker to force Salt-SSH to run their script. If an attacker has access to the target VM and knows the path to the pre-flight script before it runs they can ensure Salt-SSH runs their script with the privileges of the user running Salt-SSH. Do not make the copy path on the target predictable and ensure we check return codes of the scp command if the copy fails.

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-2026-1484 Severity: Important CVSS3 score: 8.1

Description: A flaw was found in the GLib Base64 encoding routine when processing very large input data. Due to incorrect use of integer types during length calculation, the library may miscalculate buffer boundaries. This can cause memory writes outside the allocated buffer. Applications that process untrusted or extremely large Base64 input using GLib may crash or behave unpredictably.

CVE-2026-1489 Severity: Important CVSS3 score: 8.1

Description: A flaw was found in GLib. An integer overflow vulnerability in its Unicode case conversion implementation can lead to memory corruption. By processing specially crafted and extremely large Unicode strings, an attacker could trigger an undersized memory allocation, resulting in out-of-bounds writes. This could cause applications utilizing GLib for string conversion to crash or become unstable.

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

Description: In the Linux kernel, the following vulnerability has been resolved:net: tls: handle backlogging of crypto requestsSince we're setting the CRYPTO_TFM_REQ_MAY_BACKLOG flag on ourrequests to the crypto API, crypto_aead_{encrypt,decrypt} can return -EBUSY instead of -EINPROGRESS in valid situations. For example, whenthe cryptd queue for AESNI is full (easy to trigger with anartificially low cryptd.cryptd_max_cpu_qlen), requests will be enqueuedto the backlog but still processed. In that case, the async callbackwill also be called twice: first with err == -EINPROGRESS, which itseems we can just ignore, then with err == 0.Compared to Sabrina's original patch this version uses the newtls_*crypt_async_wait() helpers and converts the EBUSY toEINPROGRESS to avoid having to modify all the error handlingpaths. The handling is identical.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:macvlan: fix error recovery in macvlan_common_newlink()valis provided a nice repro to crash the kernel:ip link add p1 type veth peer p2ip link set address 00:00:00:00:00:20 dev p1ip link set up dev p1ip link set up dev p2ip link add mv0 link p2 type macvlan mode sourceip link add invalid% link p2 type macvlan mode source macaddr add 00:00:00:00:00:20ping -c1 -I p1 1.2.3.4He also gave a very detailed analysis:The issue is triggered when a new macvlan link is created withMACVLAN_MODE_SOURCE mode and MACVLAN_MACADDR_ADD (orMACVLAN_MACADDR_SET) parameter, lower device already has a macvlanport and register_netdevice() called from macvlan_common_newlink()fails (e.g. because of the invalid link name).In this case macvlan_hash_add_source is called frommacvlan_change_sources() / macvlan_common_newlink():This adds a reference to vlan to the port's vlan_source_hash usingmacvlan_source_entry.vlan is a pointer to the priv data of the link that is being created.When register_netdevice() fails, the error is returned frommacvlan_newlink() to rtnl_newlink_create(): if (ops->newlink) err = ops->newlink(dev, ¶ms, extack); else err = register_netdevice(dev); if (err < 0) { free_netdev(dev); goto out; }and free_netdev() is called, causing a kvfree() on the structnet_device that is still referenced in the source entry attached tothe lower device's macvlan port.Now all packets sent on the macvlan port with a matching source macaddress will trigger a use-after-free in macvlan_forward_source().With all that, my fix is to make sure we call macvlan_flush_sources()regardless of @create value whenever "goto destroy_macvlan_port;"path is taken.Many thanks to valis for following up on this issue.

CVE-2026-34990 Severity: Important CVSS3 score: 7.8

Description: OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, a local unprivileged user can coerce cupsd into authenticating to an attacker-controlled localhost IPP service with a reusable Authorization: Local ... token. That token is enough to drive /admin/ requests on localhost, and the attacker can combine CUPS-Create-Local-Printer with printer-is-shared=true to persist a file:///... queue even though the normal FileDevice policy rejects such URIs. Printing to that queue gives an arbitrary root file overwrite; the PoC below uses that primitive to drop a sudoers fragment and demonstrate root command execution. At time of publication, there are no publicly available patches.

CVE-2026-4105 Severity: Important CVSS3 score: 7.8

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.

CVE-2021-3449 Severity: Important CVSS3 score: 7.5

Description: An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).

CVE-2025-68813 Severity: Important CVSS3 score: 7.5

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. The error path calls dst_link_failure(skb) with skb->dev == NULL4. ipv4_link_failure() -> ipv4_send_dest_unreach() -> __ip_options_compile() -> fib_compute_spec_dst()5. fib_compute_spec_dst() dereferences NULL skb->devApply the same fix used for IPv6 in commit 326bf17ea5d4 ("ipvs: fixipv6 route unreach panic"): set skb->dev from skb_dst(skb)->dev beforecalling dst_link_failure().KASAN: null-ptr-deref in range [0x0000000000000328-0x000000000000032f]CPU: 1 PID: 12732 Comm: syz.1.3469 Not tainted 6.6.114 #2RIP: 0010:__in_dev_get_rcu include/linux/inetdevice.h:233RIP: 0010:fib_compute_spec_dst+0x17a/0x9f0 net/ipv4/fib_frontend.c:285Call Trace: spec_dst_fill net/ipv4/ip_options.c:232 spec_dst_fill net/ipv4/ip_options.c:229 __ip_options_compile+0x13a1/0x17d0 net/ipv4/ip_options.c:330 ipv4_send_dest_unreach net/ipv4/route.c:1252 ipv4_link_failure+0x702/0xb80 net/ipv4/route.c:1265 dst_link_failure include/net/dst.h:437 __ip_vs_get_out_rt+0x15fd/0x19e0 net/netfilter/ipvs/ip_vs_xmit.c:412 ip_vs_nat_xmit+0x1d8/0xc80 net/netfilter/ipvs/ip_vs_xmit.c:764

Description: In the Linux kernel, the following vulnerability has been resolved:ipv6: BUG() in pskb_expand_head() as part of calipso_skbuff_setattr()There exists a kernel oops caused by a BUG_ON(nhead < 0) atnet/core/skbuff.c:2232 in pskb_expand_head().This bug is triggered as part of the calipso_skbuff_setattr()routine when skb_cow() is passed headroom > INT_MAX(i.e. (int)(skb_headroom(skb) + len_delta) < 0).The root cause of the bug is due to an implicit integer cast in__skb_cow(). The check (headroom > skb_headroom(skb)) is meant to ensurethat delta = headroom - skb_headroom(skb) is never negative, otherwisewe will trigger a BUG_ON in pskb_expand_head(). However, ifheadroom > INT_MAX and delta <= -NET_SKB_PAD, the check passes, deltabecomes negative, and pskb_expand_head() is passed a negative value fornhead.Fix the trigger condition in calipso_skbuff_setattr().

CVE-2026-1965 Severity: Important CVSS3 score: 7.5

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: nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. Prior to version 1.68.1, the nghttp2 library stops reading the incoming data when user facing public API `nghttp2_session_terminate_session` or `nghttp2_session_terminate_session2` is called by the application. 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.

CVE-2026-28388 Severity: Important CVSS3 score: 7.5

Description: Issue summary: When a delta CRL that contains a Delta CRL Indicator extensionis processed a NULL pointer dereference might happen if the required CRLNumber extension is missing.Impact summary: A NULL pointer dereference can trigger a crash whichleads to a Denial of Service for an application.When CRL processing and delta CRL processing is enabled during X.509certificate verification, the delta CRL processing does not checkwhether the CRL Number extension is NULL before dereferencing it.When a malformed delta CRL file is being processed, this parametercan be NULL, causing a NULL pointer dereference.Exploiting this issue requires the X509_V_FLAG_USE_DELTAS flag to be enabled inthe verification context, the certificate being verified to contain afreshestCRL extension or the base CRL to have the EXFLAG_FRESHEST flag set, andan attacker to provide a malformed CRL to an application that processes it.The vulnerability is limited to Denial of Service and cannot be escalated toachieve code execution or memory disclosure. For that reason the issue wasassessed as Low 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 affected code is outside the OpenSSL FIPS module boundary.

CVE-2026-30922 Severity: Important CVSS3 score: 7.5

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). The fix for CVE-2026-23490 (`MAX_OID_ARC_CONTINUATION_OCTETS`) does not mitigate this recursion issue. Version 0.6.3 fixes this specific issue.

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.

CVE-2018-1000030 Severity: Important CVSS3 score: 7.0

Description: Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable however this has not been confirmed. The vulnerability lies when multiply threads are handling large amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer without knowing how much to write. So when a large amount of data is being processed, it is very easy to cause memory corruption using a Heap-Buffer-Overflow. As for the Use-After-Free, Thread3->Malloc->Thread1->Free's->Thread2-Re-uses-Free'd Memory. The PSRT has stated that this is not a security vulnerability due to the fact that the attacker must be able to run code, however in some situations, such as function as a service, this vulnerability can potentially be used by an attacker to violate a trust boundary, as such the DWF feels this issue deserves a CVE.

When this happens qlen_notify() may beskipped on the parent during destruction, leaving a dangling pointerfor some classful qdiscs like DRR.There are two ways for the bug happen:- If the duplicated packet is dropped by rootq->enqueue() and then the original packet is also dropped.- If rootq->enqueue() sends the duplicated packet to a different qdisc and the original packet is dropped.In both cases NET_XMIT_SUCCESS is returned even though no packetsare enqueued at the netem qdisc.The fix is to defer the enqueue of the duplicate packet until afterthe original packet has been guaranteed to return NET_XMIT_SUCCESS.

CVE-2025-40215 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:xfrm: delete x->tunnel as we delete xThe ipcomp fallback tunnels currently get deleted (from the variouslists and hashtables) as the last user state that needed that fallbackis destroyed (not deleted). If a reference to that user state stillexists, the fallback state will remain on the hashtables/lists,triggering the WARN in xfrm_state_fini. 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-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:apparmor: fix unprivileged local user can do privileged policy managementAn unprivileged local user can load, replace, and remove profiles byopening the apparmorfs interfaces, via a confused deputy attack, bypassing the opened fd to a privileged process, and getting theprivileged process to write to the interface.This does require a privileged target that can be manipulated to dothe write for the unprivileged process, but once such access isachieved full policy management is possible and all the possibleimplications that implies: removing confinement, DoS of system ortarget applications by denying all execution, by-passing theunprivileged user namespace restriction, to exploiting kernel bugs fora local privilege escalation.The policy management interface can not have its permissions simplychanged from 0666 to 0600 because non-root processes need to be ableto load policy to different policy namespaces.Instead ensure the task writing the interface has privileges thatare a subset of the task that opened the interface. This is alreadydone via policy for confined processes, but unconfined can delegateaccess to the opened fd, by-passing the usual policy check.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nf_tables: unconditionally bump set->nelems before insertionIn case that the set is full, a new element gets published then removedwithout waiting for the RCU grace period, while RCU reader can bewalking over it already.To address this issue, add the element transaction even if set is full,but toggle the set_full flag to report -ENFILE so the abort path safelyunwinds the set to its previous state.As for element updates, decrement set->nelems to restore it.A simpler fix is to call synchronize_rcu() in the error path.However, with a large batch adding elements to already maxed-out set,this could cause noticeable slowdown of such batches.

CVE-2026-23458 Severity: Important CVSS3 score: 7.0

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.

CVE-2026-25646 Severity: Important CVSS3 score: 7.0

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.

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.

A type number is the identifier of thebinary blobs in the tracing ring buffer (known as events) to map them tologic that can parse the binary blob.The issue is that if a dynamic event (like a kprobe event) is traced andis in the ring buffer, and then that event is removed (because it isdynamic, which means it can be created and destroyed), if another dynamicevent is created that has the same number that new event's logic onparsing the binary blob will be used.To show how this can be an issue, the following can crash the kernel: # cd /sys/kernel/tracing # for i in `seq 65536`; do echo 'p:kprobes/foo do_sys_openat2 $arg1:u32' > kprobe_events # doneFor every iteration of the above, the writing to the kprobe_events willremove the old event and create a new one (with the same format) andincrease the type number to the next available on until the type numberreaches over 65535 which is the max number for the 16 bit type. After itreaches that number, the logic to allocate a new number simply looks forthe next available number. When an dynamic event is removed, that numberis then available to be reused by the next dynamic event created. That is,once the above reaches the max number, the number assigned to the event inthat loop will remain the same.Now that means deleting one dynamic event and created another will reusethe previous events type number. This is where bad things can happen.After the above loop finishes, the kprobes/foo event which reads thedo_sys_openat2 function call's first parameter as an integer. # echo 1 > kprobes/foo/enable # cat /etc/passwd > /dev/null # cat trace cat-2211 [005] .... 2007.849603: foo: (do_sys_openat2+0x0/0x130) arg1=4294967196 cat-2211 [005] .... 2007.849620: foo: (do_sys_openat2+0x0/0x130) arg1=4294967196 cat-2211 [005] .... 2007.849838: foo: (do_sys_openat2+0x0/0x130) arg1=4294967196 cat-2211 [005] .... 2007.849880: foo: (do_sys_openat2+0x0/0x130) arg1=4294967196 # echo 0 > kprobes/foo/enableNow if we delete the kprobe and create a new one that reads a string: # echo 'p:kprobes/foo do_sys_openat2 +0($arg2):string' > kprobe_eventsAnd now we can the trace: # cat trace sendmail-1942 [002] ..... 530.136320: foo: (do_sys_openat2+0x0/0x240) arg1= cat-2046 [004] ..... 530.930817: foo: (do_sys_openat2+0x0/0x240) arg1="��" cat-2046 [004] ..... 530.930961: foo: (do_sys_openat2+0x0/0x240) arg1="��" cat-2046 [004] ..... 530.934278: foo: (do_sys_openat2+0x0/0x240) arg1="��" cat-2046 [004] ..... 530.934563: foo: (do_sys_openat2+0x0/0x240) arg1="��---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix out-of-bounds access in ops_initnet_alloc_generic is called by net_alloc, which is called without anylocking. It reads max_gen_ptrs, which is changed under pernet_ops_rwsem. Itis read twice, first to allocate an array, then to set s.len, which islater used to limit the bounds of the array access.It is possible that the array is allocated and another thread isregistering a new pernet ops, increments max_gen_ptrs, which is then usedto set s.len with a larger than allocated length for the variable array.Fix it by reading max_gen_ptrs only once in net_alloc_generic. Ifmax_gen_ptrs is later incremented, it will be caught in net_assign_generic.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:gpio: amd8111: Fix PCI device reference count leakfor_each_pci_dev() is implemented by pci_get_device(). The comment ofpci_get_device() says that it will increase the reference count for thereturned pci_dev and also decrease the reference count for the inputpci_dev @from if it is not NULL.If we break for_each_pci_dev() loop with pdev not NULL, we need to callpci_dev_put() to decrease the reference count. Add the missingpci_dev_put() after the 'out' label. Since pci_dev_put() can handle NULLinput parameter, there is no problem for the 'Device not found' branch.For the normal path, add pci_dev_put() in amd_gpio_exit().

Otherwise, uninitmemory can be referenced.Tested on Qualcomm Atheros Communications AR9271 802.11n .Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

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.

Description: net-tools is a collection of programs that form the base set of the NET-3 networking distribution for the Linux operating system. Inn versions up to and including 2.10, the Linux network utilities (like ifconfig) from the net-tools package do not properly validate the structure of /proc files when showing interfaces. `get_name()` in `interface.c` copies interface labels from `/proc/net/dev` into a fixed 16-byte stack buffer without bounds checking, leading to possible arbitrary code execution or crash. The known attack path does not require privilege but also does not provide privilege escalation in this scenario. A patch is available and expected to be part of version 2.20.

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.

CVE-2025-8058 Severity: Moderate CVSS3 score: 6.6

Description: The regcomp function in the GNU C library version from 2.4 to 2.41 is subject to a double free if some previous allocation fails. It can be accomplished either by a malloc failure or by using an interposed malloc that injects random malloc failures. The double free can allow buffer manipulation depending of how the regex is constructed. This issue affects all architectures and ABIs supported by the GNU C library.

CVE-2026-25749 Severity: Moderate CVSS3 score: 6.6

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.

CVE-2025-21681 Severity: Moderate CVSS3 score: 6.5

Description: In the Linux kernel, the following vulnerability has been resolved:openvswitch: fix lockup on tx to unregistering netdev with carrierCommit in a fixes tag attempted to fix the issue in the followingsequence of calls: do_output -> ovs_vport_send -> dev_queue_xmit -> __dev_queue_xmit -> netdev_core_pick_tx -> skb_tx_hashWhen device is unregistering, the 'dev->real_num_tx_queues' goes tozero and the 'while (unlikely(hash >= qcount))' loop inside the'skb_tx_hash' becomes infinite, locking up the core forever.But unfortunately, checking just the carrier status is not enough tofix the issue, because some devices may still be in unregisteringstate while reporting carrier status OK.One example of such device is a net/dummy. It sets carrier ONon start, but it doesn't implement .ndo_stop to set the carrier off.And it makes sense, because dummy doesn't really have a carrier.Therefore, while this device is unregistering, it's still easy to hitthe infinite loop in the skb_tx_hash() from the OVS datapath. Theremight be other drivers that do the same, but dummy by itself isimportant for the OVS ecosystem, because it is frequently used as apacket sink for tcpdump while debugging OVS deployments. And when theissue is hit, the only way to recover is to reboot.Fix that by also checking if the device is running. The runningstate is handled by the net core during unregistering, so it coversunregistering case better, and we don't really need to send packetsto devices that are not running anyway.While only checking the running state might be enough, the carriercheck is preserved. The running and the carrier states seem disjoinedthroughout the code and different drivers. And other core functionslike __dev_direct_xmit() check both before attempting to transmita packet. So, it seems safer to check both flags in OVS as well.

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).

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.

Description: Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. In versions 0.9rc2 and below, avahi-daemon can be crashed via a segmentation fault by sending an unsolicited mDNS response containing a recursive CNAME record, where the alias and canonical name point to the same domain (e.g., "h.local" as a CNAME for "h.local"). This causes unbounded recursion in the lookup_handle_cname function, leading to stack exhaustion. The vulnerability affects record browsers where AVAHI_LOOKUP_USE_MULTICAST is set explicitly, which includes record browsers created by resolvers used by nss-mdns. This issue is patched in commit 78eab31128479f06e30beb8c1cbf99dd921e2524.

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.

Description: OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, the RSS notifier allows .. path traversal in notify-recipient-uri (e.g., rss:///../job.cache), letting a remote IPP client write RSS XML bytes outside CacheDir/rss (anywhere that is lp-writable). In particular, because CacheDir is group-writable by default (typically root:lp and mode 0770), the notifier (running as lp) can replace root-managed state files via temp-file + rename(). This PoC clobbers CacheDir/job.cache with RSS XML, and after restarting cupsd the scheduler fails to parse the job cache and previously queued jobs disappear. At time of publication, there are no publicly available patches.

This may lead to a use-after-freecondition that was observed with nvme-tcp.The race condition may happen in the following scenario:1. driver executes its reset_ctrl_work2. -> nvme_stop_ctrl - flushes ctrl async_event_work3. ctrl sends AEN which is received by the host, which in turn schedules AEN handling4. teardown admin queue (which releases the queue socket)5. AEN processed, submits another AER, calling the driver to submit6. driver attempts to send the cmd==> use-after-freeIn order to fix that, add ctrl state check to validate the ctrlis actually able to accept the AER submission.This addresses the above race in controller resets because the driverduring teardown should:1. change ctrl state to RESETTING2. flush async_event_work (as well as other async work elements)So after 1,2, any other AER command will find thectrl state to be RESETTING and bail out without submitting the AER.

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.

CVE-2025-39759 Severity: Moderate CVSS3 score: 6.4

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.

CVE-2026-23340 Severity: Moderate CVSS3 score: 6.4

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.

CVE-2026-34980 Severity: Moderate CVSS3 score: 6.4

Description: OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, in a network-exposed cupsd with a shared target queue, an unauthorized client can send a Print-Job to that shared PostScript queue without authentication. The server accepts a page-border value supplied as textWithoutLanguage, preserves an embedded newline through option escaping and reparse, and then reparses the resulting second-line PPD: text as a trusted scheduler control record. A follow-up raw print job can therefore make the server execute an attacker-chosen existing binary such as /usr/bin/vim as lp. At time of publication, there are no publicly available patches.

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-2025-71152 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-2026-23262 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.

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.

Inthis case, iterator->_next_ns_data isn't initialized (it'sonly set for skipping vendor namespaces), and syzbot pointsout that we later compare against this uninitialized value.Fix this by moving the rejection of unknown radiotap fieldsdown to after the in-namespace lookup, so it will really useiterator->_next_ns_data only for vendor namespaces, even incase undefined fields are present.

Description: Perl threads have a working directory race condition where file operations may target unintended paths.If a directory handle is open at thread creation, the process-wide current working directory is temporarily changed in order to clone that handle for the new thread, which is visible from any third (or more) thread already running. This may lead to unintended operations such as loading code or accessing files from unexpected locations, which a local attacker may be able to exploit.The bug was introduced in commit 11a11ecf4bea72b17d250cfb43c897be1341861e and released in Perl version 5.13.6

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.

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-2025-39716 Severity: Moderate CVSS3 score: 6.1

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-2025-39998 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.

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: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-2026-31392 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: fix krb5 mount with username optionCustomer reported that some of their krb5 mounts were failing againsta single server as the client was trying to mount the shares withwrong credentials. It turned out the client was reusing SMB sessionfrom first mount to try mounting the other shares, even though adifferent username= option had been specified to the other mounts.By using username mount option along with sec=krb5 to search forprincipals from keytab is supported by cifs.upcall(8) sincecifs-utils-4.8. So fix this by matching username mount option inmatch_session() even with Kerberos.For example, the second mount below should fail with -ENOKEY as thereis no 'foobar' principal in keytab (/etc/krb5.keytab). The clientends up reusing SMB session from first mount to perform the secondone, which is wrong.```$ ktutilktutil: add_entry -password -p testuser -k 1 -e aes256-ctsPassword for testuser@ZELDA.TEST:ktutil: write_kt /etc/krb5.keytabktutil: quit$ klist -keKeytab name: FILE:/etc/krb5.keytabKVNO Principal ---- ---------------------------------------------------------------- 1 testuser@ZELDA.TEST (aes256-cts-hmac-sha1-96)$ mount.cifs //w22-root2/scratch /mnt/1 -o sec=krb5,username=testuser$ mount.cifs //w22-root2/scratch /mnt/2 -o sec=krb5,username=foobar$ mount -t cifs | grep -Po 'username=\K\w+'testusertestuser```

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-2019-1549 Severity: Moderate CVSS3 score: 5.9

Description: OpenSSL 1.1.1 introduced a rewritten random number generator (RNG). This was intended to include protection in the event of a fork() system call in order to ensure that the parent and child processes did not share the same RNG state. However this protection was not being used in the default case. A partial mitigation for this issue is that the output from a high precision timer is mixed into the RNG state so the likelihood of a parent and child process sharing state is significantly reduced. If an application already calls OPENSSL_init_crypto() explicitly using OPENSSL_INIT_ATFORK then this problem does not occur at all. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c).

CVE-2024-36905 Severity: Moderate CVSS3 score: 5.9

Description: In the Linux kernel, the following vulnerability has been resolved:tcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV socketsTCP_SYN_RECV state is really special, it is only used bycross-syn connections, mostly used by fuzzers.In the following crash [1], syzbot managed to trigger a divideby zero in tcp_rcv_space_adjust()A socket makes the following state transitions,without ever calling tcp_init_transfer(),meaning tcp_init_buffer_space() is also not called. TCP_CLOSEconnect() TCP_SYN_SENT TCP_SYN_RECVshutdown() -> tcp_shutdown(sk, SEND_SHUTDOWN) TCP_FIN_WAIT1To fix this issue, change tcp_shutdown() to notperform a TCP_SYN_RECV -> TCP_FIN_WAIT1 transition,which makes no sense anyway.When tcp_rcv_state_process() later changes socket statefrom TCP_SYN_RECV to TCP_ESTABLISH, then look atsk->sk_shutdown to finally enter TCP_FIN_WAIT1 state,and send a FIN packet from a sane socket state.This means tcp_send_fin() can now be called from BHcontext, and must use GFP_ATOMIC allocations.[1]divide error: 0000 [#1] PREEMPT SMP KASAN NOPTICPU: 1 PID: 5084 Comm: syz-executor358 Not tainted 6.9.0-rc6-syzkaller-00022-g98369dccd2f8 #0Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 03/27/2024 RIP: 0010:tcp_rcv_space_adjust+0x2df/0x890 net/ipv4/tcp_input.c:767Code: e3 04 4c 01 eb 48 8b 44 24 38 0f b6 04 10 84 c0 49 89 d5 0f 85 a5 03 00 00 41 8b 8e c8 09 00 00 89 e8 29 c8 48 0f af c3 31 d2 <48> f7 f1 48 8d 1c 43 49 8d 96 76 08 00 00 48 89 d0 48 c1 e8 03 48RSP: 0018:ffffc900031ef3f0 EFLAGS: 00010246RAX: 0c677a10441f8f42 RBX: 000000004fb95e7e RCX: 0000000000000000RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000000RBP: 0000000027d4b11f R08: ffffffff89e535a4 R09: 1ffffffff25e6ab7R10: dffffc0000000000 R11: ffffffff8135e920 R12: ffff88802a9f8d30R13: dffffc0000000000 R14: ffff88802a9f8d00 R15: 1ffff1100553f2daFS: 00005555775c0380(0000) GS:ffff8880b9500000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007f1155bf2304 CR3: 000000002b9f2000 CR4: 0000000000350ef0Call Trace: tcp_recvmsg_locked+0x106d/0x25a0 net/ipv4/tcp.c:2513 tcp_recvmsg+0x25d/0x920 net/ipv4/tcp.c:2578 inet6_recvmsg+0x16a/0x730 net/ipv6/af_inet6.c:680 sock_recvmsg_nosec net/socket.c:1046 [inline] sock_recvmsg+0x109/0x280 net/socket.c:1068 ____sys_recvmsg+0x1db/0x470 net/socket.c:2803 ___sys_recvmsg net/socket.c:2845 [inline] do_recvmmsg+0x474/0xae0 net/socket.c:2939 __sys_recvmmsg net/socket.c:3018 [inline] __do_sys_recvmmsg net/socket.c:3041 [inline] __se_sys_recvmmsg net/socket.c:3034 [inline] __x64_sys_recvmmsg+0x199/0x250 net/socket.c:3034 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xf5/0x240 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7fRIP: 0033:0x7faeb6363db9Code: 28 00 00 00 75 05 48 83 c4 28 c3 e8 c1 17 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 b8 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007ffcc1997168 EFLAGS: 00000246 ORIG_RAX: 000000000000012bRAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007faeb6363db9RDX: 0000000000000001 RSI: 0000000020000bc0 RDI: 0000000000000005RBP: 0000000000000000 R08: 0000000000000000 R09: 000000000000001cR10: 0000000000000122 R11: 0000000000000246 R12: 0000000000000000R13: 0000000000000000 R14: 0000000000000001 R15: 0000000000000001

CVE-2025-68972 Severity: Moderate CVSS3 score: 5.9

Description: In GnuPG through 2.4.8, if a signed message has \f at the end of a plaintext line, an adversary can construct a modified message that places additional text after the signed material, such that signature verification of the modified message succeeds (although an "invalid armor" message is printed during verification). This is related to use of \f as a marker to denote truncation of a long plaintext line.

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:netrom: fix double-free in nr_route_frame()In nr_route_frame(), old_skb is immediately freed without checking ifnr_neigh->ax25 pointer is NULL. Therefore, if nr_neigh->ax25 is NULL,the caller function will free old_skb again, causing a double-free bug.Therefore, to prevent this, we need to modify it to check whethernr_neigh->ax25 is NULL before freeing old_skb.

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.

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.

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-2025-68795 Severity: Moderate CVSS3 score: 5.8

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.

CVE-2019-1547 Severity: Moderate CVSS3 score: 5.5

Description: Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters (instead of using a named curve). In those cases it is possible that such a group does not have the cofactor present. This can occur even where all the parameters match a known named curve. If such a curve is used then OpenSSL falls back to non-side channel resistant code paths which may result in full key recovery during an ECDSA signature operation. In order to be vulnerable an attacker would have to have the ability to time the creation of a large number of signatures where explicit parameters with no co-factor present are in use by an application using libcrypto. For the avoidance of doubt libssl is not vulnerable because explicit parameters are never used. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL 1.1.0l (Affected 1.1.0-1.1.0k).

CVE-2021-46987 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix deadlock when cloning inline extents and using qgroupsThere are a few exceptional cases where cloning an inline extent needs tocopy the inline extent data into a page of the destination inode.When this happens, we end up starting a transaction while having a dirtypage for the destination inode and while having the range locked in thedestination's inode iotree too. Because when reserving metadata spacefor a transaction we may need to flush existing delalloc in case there isnot enough free space, we have a mechanism in place to prevent a deadlock,which was introduced in commit 3d45f221ce627d ("btrfs: fix deadlock whencloning inline extent and low on free metadata space").However when using qgroups, a transaction also reserves metadata qgroupspace, which can also result in flushing delalloc in case there is notenough available space at the moment. When this happens we deadlock, sinceflushing delalloc requires locking the file range in the inode's iotreeand the range was already locked at the very beginning of the cloneoperation, before attempting to start the transaction.When this issue happens, stack traces like the following are reported: [72747.556262] task:kworker/u81:9 state:D stack: 0 pid: 225 ppid: 2 flags:0x00004000 [72747.556268] Workqueue: writeback wb_workfn (flush-btrfs-1142) [72747.556271] Call Trace: [72747.556273] __schedule+0x296/0x760 [72747.556277] schedule+0x3c/0xa0 [72747.556279] io_schedule+0x12/0x40 [72747.556284] __lock_page+0x13c/0x280 [72747.556287] ? generic_file_readonly_mmap+0x70/0x70 [72747.556325] extent_write_cache_pages+0x22a/0x440 [btrfs] [72747.556331] ? __set_page_dirty_nobuffers+0xe7/0x160 [72747.556358] ? set_extent_buffer_dirty+0x5e/0x80 [btrfs] [72747.556362] ? update_group_capacity+0x25/0x210 [72747.556366] ? cpumask_next_and+0x1a/0x20 [72747.556391] extent_writepages+0x44/0xa0 [btrfs] [72747.556394] do_writepages+0x41/0xd0 [72747.556398] __writeback_single_inode+0x39/0x2a0 [72747.556403] writeback_sb_inodes+0x1ea/0x440 [72747.556407] __writeback_inodes_wb+0x5f/0xc0 [72747.556410] wb_writeback+0x235/0x2b0 [72747.556414] ? get_nr_inodes+0x35/0x50 [72747.556417] wb_workfn+0x354/0x490 [72747.556420] ? newidle_balance+0x2c5/0x3e0 [72747.556424] process_one_work+0x1aa/0x340 [72747.556426] worker_thread+0x30/0x390 [72747.556429] ? create_worker+0x1a0/0x1a0 [72747.556432] kthread+0x116/0x130 [72747.556435] ? kthread_park+0x80/0x80 [72747.556438] ret_from_fork+0x1f/0x30 [72747.566958] Workqueue: btrfs-flush_delalloc btrfs_work_helper [btrfs] [72747.566961] Call Trace: [72747.566964] __schedule+0x296/0x760 [72747.566968] ? finish_wait+0x80/0x80 [72747.566970] schedule+0x3c/0xa0 [72747.566995] wait_extent_bit.constprop.68+0x13b/0x1c0 [btrfs] [72747.566999] ? finish_wait+0x80/0x80 [72747.567024] lock_extent_bits+0x37/0x90 [btrfs] [72747.567047] btrfs_invalidatepage+0x299/0x2c0 [btrfs] [72747.567051] ? find_get_pages_range_tag+0x2cd/0x380 [72747.567076] __extent_writepage+0x203/0x320 [btrfs] [72747.567102] extent_write_cache_pages+0x2bb/0x440 [btrfs] [72747.567106] ? update_load_avg+0x7e/0x5f0 [72747.567109] ? enqueue_entity+0xf4/0x6f0 [72747.567134] extent_writepages+0x44/0xa0 [btrfs] [72747.567137] ? enqueue_task_fair+0x93/0x6f0 [72747.567140] do_writepages+0x41/0xd0 [72747.567144] __filemap_fdatawrite_range+0xc7/0x100 [72747.567167] btrfs_run_delalloc_work+0x17/0x40 [btrfs] [72747.567195] btrfs_work_helper+0xc2/0x300 [btrfs] [72747.567200] process_one_work+0x1aa/0x340 [72747.567202] worker_thread+0x30/0x390 [72747.567205] ? create_worker+0x1a0/0x1a0 [72747.567208] kthread+0x116/0x130 [72747.567211] ? kthread_park+0x80/0x80 [72747.567214] ret_from_fork+0x1f/0x30 [72747.569686] task:fsstress state:D stack: ---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:net: bridge: fix vlan tunnel dst null pointer dereferenceThis patch fixes a tunnel_dst null pointer dereference due to locklessaccess in the tunnel egress path. When deleting a vlan tunnel thetunnel_dst pointer is set to NULL without waiting a grace period (i.e.while it's still usable) and packets egressing are dereferencing itwithout checking. Use READ/WRITE_ONCE to annotate the lockless use oftunnel_id, use RCU for accessing tunnel_dst and make sure it is readonly once and checked in the egress path. The dst is already properly RCUprotected so we don't need to do anything fancy than to make suretunnel_id and tunnel_dst are read only once and checked in the egress path.

Description: In the Linux kernel, the following vulnerability has been resolved:mac80211-hwsim: fix late beacon hrtimer handlingThomas explained in https://lore.kernel.org/r/87mtoeb4hb.ffs@tglxthat our handling of the hrtimer here is wrong: If the timer fireslate (e.g. due to vCPU scheduling, as reported by Dmitry/syzbot)then it tries to actually rearm the timer at the next deadline,which might be in the past already: 1 2 3 N N+1 | | | ... | | ^ intended to fire here (1) ^ next deadline here (2) ^ actually fired hereThe next time it fires, it's later, but will still try to schedulefor the next deadline (now 3), etc. until it catches up with N,but that might take a long time, causing stalls etc.Now, all of this is simulation, so we just have to fix it, butnote that the behaviour is wrong even per spec, since there's novalue then in sending all those beacons unaligned - they should bealigned to the TBTT (1, 2, 3, ... in the picture), and if we're abit (or a lot) late, then just resume at that point.Therefore, change the code to use hrtimer_forward_now() which willensure that the next firing of the timer would be at N+1 (in thepicture), i.e. the next interval point after the current time.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix abort logic in btrfs_replace_file_extentsError injection testing uncovered a case where we'd end up with acorrupt file system with a missing extent in the middle of a file. Thisoccurs because the if statement to decide if we should abort is wrong.The only way we would abort in this case is if we got a ret !=-EOPNOTSUPP and we called from the file clone code. However theprealloc code uses this path too. Instead we need to abort if there isan error, and the only error we _don't_ abort on is -EOPNOTSUPP and onlyif we came from the clone file code.

CVE-2022-48809 Severity: Moderate CVSS3 score: 5.5

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.

However, it's not necessary to make such a large changein order to fix this bug; all we need to do is make sure thatudc->dev.driver is always NULL.In fact, there is no reason for udc->dev.driver ever to be set toanything, let alone to the value it currently gets: the address of thegadget's driver. After all, a gadget driver only knows how to managea gadget, not how to manage a UDC.This patch simply removes the statements in the gadget core that touchudc->dev.driver.

CVE-2022-48853 Severity: Moderate CVSS3 score: 5.5

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.

Description: In the Linux kernel, the following vulnerability has been resolved:rtc: cmos: Fix event handler registration ordering issueBecause acpi_install_fixed_event_handler() enables the eventautomatically on success, it is incorrect to call it before thehandler routine passed to it is ready to handle events.Unfortunately, the rtc-cmos driver does exactly the incorrect thingby calling cmos_wake_setup(), which passes rtc_handler() toacpi_install_fixed_event_handler(), before cmos_do_probe(), becausertc_handler() uses dev_get_drvdata() to get to the cmos objectpointer and the driver data pointer is only populated incmos_do_probe().This leads to a NULL pointer dereference in rtc_handler() on bootif the RTC fixed event happens to be active at the init time.To address this issue, change the initialization ordering of thedriver so that cmos_wake_setup() is always called after a successfulcmos_do_probe() call.While at it, change cmos_pnp_probe() to call cmos_do_probe() afterthe initial if () statement used for computing the IRQ argument tobe passed to cmos_do_probe() which is cleaner than calling it ineach branch of that if () (local variable "irq" can be of type int,because it is passed to that function as an argument of type int).Note that commit 6492fed7d8c9 ("rtc: rtc-cmos: Do not checkACPI_FADT_LOW_POWER_S0") caused this issue to affect a larger numberof systems, because previously it only affected systems withACPI_FADT_LOW_POWER_S0 set, but it is present regardless of thatcommit.

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(). The broken vqmeant that vring_interrupt() skipped the vq.callback() that would havecompleted the virtio I/O operation via virtblk_done().[bhelgaas: commit log, simplify to always use pci_physfn(), add stable tag]

CVE-2022-50668 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: fix deadlock due to mbcache entry corruptionWhen manipulating xattr blocks, we can deadlock infinitely loopinginside ext4_xattr_block_set() where we constantly keep finding xattrblock for reuse in mbcache but we are unable to reuse it because itsreference count is too big. 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").

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.

However, this leads to the data inbulk_in_buffer[HEADER..IMGSIZE] uninitialized. And the checkfor valid image incurs an uninitialized dereference.Fix this by moving the check before reset label since thischeck only be valid if the data after bulk_in_buffer[HEADER]has concrete data.Note that this is found by KMSAN, so only kernel compilationis tested.

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.

Therefore, when using this macro, it is necessary to check inadvance that the device size is not less than a lower limit, or at leastthat underflow does not occur.The current nilfs2 implementation lacks this check, causing out-of-boundblock access when mounting devices smaller than 4096 bytes: I/O error, dev loop0, sector 36028797018963960 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 2 NILFS (loop0): unable to read secondary superblock (blocksize = 1024)In addition, when trying to resize the filesystem to a size below 4096bytes, this underflow occurs in nilfs_resize_fs(), passing a huge numberof segments to nilfs_sufile_resize(), corrupting parameters such as thenumber of segments in superblocks.

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.

CVE-2023-52854 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:padata: Fix refcnt handling in padata_free_shell()In a high-load arm64 environment, the pcrypt_aead01 test in LTP can leadto system UAF (Use-After-Free) issues. Due to the lengthy analysis ofthe pcrypt_aead01 function call, I'll describe the problem scenariousing a simplified model:Suppose there's a user of padata named `user_function` that adheres tothe padata requirement of calling `padata_free_shell` after `serial()`has been invoked, as demonstrated in the following code:```cstruct request { struct padata_priv padata; struct completion *done;};void parallel(struct padata_priv *padata) { do_something();}void serial(struct padata_priv *padata) { struct request *request = container_of(padata, struct request, padata); complete(request->done);}void user_function() { DECLARE_COMPLETION(done) padata->parallel = parallel; padata->serial = serial; padata_do_parallel(); wait_for_completion(&done); padata_free_shell();}```In the corresponding padata.c file, there's the following code:```cstatic void padata_serial_worker(struct work_struct *serial_work) { ... cnt = 0; while (!list_empty(&local_list)) { ... padata->serial(padata); cnt++; } local_bh_enable(); if (refcount_sub_and_test(cnt, &pd->refcnt)) padata_free_pd(pd);}```Because of the high system load and the accumulation of unexecutedsoftirq at this moment, `local_bh_enable()` in padata takes longerto execute than usual. Subsequently, when accessing `pd->refcnt`,`pd` has already been released by `padata_free_shell()`, resultingin a UAF issue with `pd->refcnt`.The fix is straightforward: add `refcount_dec_and_test` before calling`padata_free_pd` in `padata_free_shell`.

Description: In the Linux kernel, the following vulnerability has been resolved:l2tp: close all race conditions in l2tp_tunnel_register()The code in l2tp_tunnel_register() is racy in several ways:1. It modifies the tunnel socket _after_ publishing it.2. It calls setup_udp_tunnel_sock() on an existing socket without locking.3. It changes sock lock class on fly, which triggers many syzbot reports.This patch amends all of them by moving socket initialization codebefore publishing and under sock lock. As suggested by Jakub, thel2tp lockdep class is not necessary as we can just switch tobh_lock_sock_nested().

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.

Description: In the Linux kernel, the following vulnerability has been resolved:kcm: Fix error handling for SOCK_DGRAM in kcm_sendmsg().syzkaller found a memory leak in kcm_sendmsg(), and commit c821a88bd720("kcm: Fix memory leak in error path of kcm_sendmsg()") suppressed it byupdating kcm_tx_msg(head)->last_skb if partial data is copied so that thefollowing sendmsg() will resume from the skb.However, we cannot know how many bytes were copied when we get the error.Thus, we could mess up the MSG_MORE queue.When kcm_sendmsg() fails for SOCK_DGRAM, we should purge the queue as wedo so for UDP by udp_flush_pending_frames().Even without this change, when the error occurred, the following sendmsg()resumed from a wrong skb and the queue was messed up. 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.

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-2023-53998 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).

However, since these two readsare not atomically executed, there is a chance of a race condition asdescribed above.To fix this race condition, read vmci_host_dev->context after checkingthe value of vmci_host_dev->ct_type so that vmci_host_poll() alwaysreads an initialized context.

CVE-2023-54012 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix stack overflow when LRO is disabled for virtual interfacesWhen the virtual interface's feature is updated, it synchronizes theupdated feature for its own lower interface.This propagation logic should be worked as the iteration, not recursively.But it works recursively due to the netdev notification unexpectedly.This problem occurs when it disables LRO only for the team and bondinginterface type. team0 | +------+------+-----+-----+ | | | | |team1 team2 team3 ... team200If team0's LRO feature is updated, it generates the NETDEV_FEAT_CHANGEevent to its own lower interfaces(team1 ~ team200).It is worked by netdev_sync_lower_features().So, the NETDEV_FEAT_CHANGE notification logic of each lower interfacework iteratively.But generated NETDEV_FEAT_CHANGE event is also sent to the upperinterface too.upper interface(team0) generates the NETDEV_FEAT_CHANGE event for its ownlower interfaces again.lower and upper interfaces receive this event and generate thisevent again and again.So, the stack overflow occurs.But it is not the infinite loop issue.Because the netdev_sync_lower_features() updates features beforegenerating the NETDEV_FEAT_CHANGE event.Already synchronized lower interfaces skip notification logic.So, it is just the problem that iteration logic is changed to therecursive unexpectedly due to the notification mechanism.Reproducer:ip link add team0 type teamethtool -K team0 lro onfor i in {1..200}do ip link add team$i master team0 type team ethtool -K team$i lro ondoneethtool -K team0 lro offIn order to fix it, the notifier_ctx member of bonding/team is introduced.

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.

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.

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---

If the hardware specificdriver has initialized port->pm function, we need to clear port->pm too.Just reinitializing port->ops does not do this.

The data role swap causes the device to unregister all altmodes, however the usb hub will still send Attention messageseven after failing to reregister the Alt Mode. type_altmode_attentioncurrently does not verify whether or not a device's altmode partnerexists, which results in a NULL pointer error when dereferencingthe typec_altmode and typec_altmode_ops belonging to the altmodepartner.Verify the presence of a device's altmode partner before sendingthe Attention message to the Alt Mode driver.

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)").

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: act_mirred: use the backlog for mirred ingressThe test Davide added in commit ca22da2fbd69 ("act_mirred: use the backlogfor nested calls to mirred ingress") hangs our testing VMs every 10 or soruns, with the familiar tcp_v4_rcv -> tcp_v4_rcv deadlock reported bylockdep.The problem as previously described by Davide (see Link) is thatif we reverse flow of traffic with the redirect (egress -> ingress)we may reach the same socket which generated the packet. And we maystill be holding its socket lock. The common solution to such deadlocksis to put the packet in the Rx backlog, rather than run the Rx pathinline. Do that for all egress -> ingress reversals, not just oncewe started to nest mirred calls.In the past there was a concern that the backlog indirection willlead to loss of error reporting / less accurate stats. But the currentworkaround does not seem to address the issue.

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.

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.

And that in turn fixes the moduleunloading bug as __fput() won't do module_put() on the last vCPU referenceuntil the vCPU has been freed, e.g. if closing the vCPU file also puts thelast reference to the KVM module.Note that kvm_check_async_pf_completion() may also take the work item offthe completion queue and so also needs to flush the work queue, as thework will not be seen by kvm_clear_async_pf_completion_queue(). Waitingon the workqueue could theoretically delay a vCPU due to waiting for thework to complete, but that's a very, very small chance, and likely a verysmall delay. kvm_arch_async_page_present_queued() unconditionally makes anew request, i.e. will effectively delay entering the guest, so theremaining work is really just: trace_kvm_async_pf_completed(addr, cr2_or_gpa); __kvm_vcpu_wake_up(vcpu); mmput(mm);and mmput() can't drop the last reference to the page tables if the vCPU isstill alive, i.e. the vCPU won't get stuck tearing down page tables.Add a helper to do the flushing, specifically to deal with "wakeup all"work items, as they aren't actually work items, i.e. are never placed in aworkqueue. Trying to flush a bogus workqueue entry rightly makes__flush_work() complain (kudos to whoever added that sanity check).Note, commit 5f6de5cbebee ("KVM: Prevent module exit until al---truncated---

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]

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.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: L2CAP: Fix div-by-zero in l2cap_le_flowctl_init()l2cap_le_flowctl_init() can cause both div-by-zero and an integeroverflow since hdev->le_mtu may not fall in the valid range.Move MTU from hci_dev to hci_conn to validate MTU and stop the connectionprocess earlier if MTU is invalid.Also, add a missing validation in read_buffer_size() and make it returnan error value if the validation fails.Now hci_conn_add() returns ERR_PTR() as it can fail due to the both akzalloc failure and invalid MTU value.divide error: 0000 [#1] PREEMPT SMP KASAN NOPTICPU: 0 PID: 67 Comm: kworker/u5:0 Tainted: G W 6.9.0-rc5+ #20Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014Workqueue: hci0 hci_rx_workRIP: 0010:l2cap_le_flowctl_init+0x19e/0x3f0 net/bluetooth/l2cap_core.c:547Code: e8 17 17 0c 00 66 41 89 9f 84 00 00 00 bf 01 00 00 00 41 b8 02 00 00 00 4c89 fe 4c 89 e2 89 d9 e8 27 17 0c 00 44 89 f0 31 d2 <66> f7 f3 89 c3 ff c3 4d 8db7 88 00 00 00 4c 89 f0 48 c1 e8 03 42RSP: 0018:ffff88810bc0f858 EFLAGS: 00010246RAX: 00000000000002a0 RBX: 0000000000000000 RCX: dffffc0000000000RDX: 0000000000000000 RSI: ffff88810bc0f7c0 RDI: ffffc90002dcb66fRBP: ffff88810bc0f880 R08: aa69db2dda70ff01 R09: 0000ffaaaaaaaaaaR10: 0084000000ffaaaa R11: 0000000000000000 R12: ffff88810d65a084R13: dffffc0000000000 R14: 00000000000002a0 R15: ffff88810d65a000FS: 0000000000000000(0000) GS:ffff88811ac00000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 0000000020000100 CR3: 0000000103268003 CR4: 0000000000770ef0PKRU: 55555554Call Trace: l2cap_le_connect_req net/bluetooth/l2cap_core.c:4902 [inline] l2cap_le_sig_cmd net/bluetooth/l2cap_core.c:5420 [inline] l2cap_le_sig_channel net/bluetooth/l2cap_core.c:5486 [inline] l2cap_recv_frame+0xe59d/0x11710 net/bluetooth/l2cap_core.c:6809 l2cap_recv_acldata+0x544/0x10a0 net/bluetooth/l2cap_core.c:7506 hci_acldata_packet net/bluetooth/hci_core.c:3939 [inline] hci_rx_work+0x5e5/0xb20 net/bluetooth/hci_core.c:4176 process_one_work kernel/workqueue.c:3254 [inline] process_scheduled_works+0x90f/0x1530 kernel/workqueue.c:3335 worker_thread+0x926/0xe70 kernel/workqueue.c:3416 kthread+0x2e3/0x380 kernel/kthread.c:388 ret_from_fork+0x5c/0x90 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244 Modules linked in:---[ end trace 0000000000000000 ]---

CVE-2024-42098 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: ecdh - explicitly zeroize private_keyprivate_key is overwritten with the key parameter passed in by thecaller (if present), or alternatively a newly generated private key.However, it is possible that the caller provides a key (or the newlygenerated key) which is shorter than the previous key. In thatscenario, some key material from the previous key would not beoverwritten. The easiest solution is to explicitly zeroize the entireprivate_key array first.Note that this patch slightly changes the behavior of this function:previously, if the ecc_gen_privkey failed, the old private_key wouldremain. Now, the private_key is always zeroized. This behavior isconsistent with the case where params.key is set and ecc_is_key_validfails.

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.

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.

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-2024-46695 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:Squashfs: sanity check symbolic link sizeSyzkiller reports a "KMSAN: uninit-value in pick_link" bug.This is caused by an uninitialised page, which is ultimately causedby a corrupted symbolic link size read from disk.The reason why the corrupted symlink size causes an uninitialisedpage is due to the following sequence of events:1. squashfs_read_inode() is called to read the symbolic link from disk. This assigns the corrupted value 3875536935 to inode->i_size.2. Later squashfs_symlink_read_folio() is called, which assigns this corrupted value to the length variable, which being a signed int, overflows producing a negative number.3. The following loop that fills in the page contents checks that the copied bytes is less than length, which being negative means the loop is skipped, producing an uninitialised page.This patch adds a sanity check which checks that the symboliclink size is not larger than expected.--V2: fix spelling mistake.

CVE-2024-46745 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:Input: uinput - reject requests with unreasonable number of slotsWhen exercising uinput interface syzkaller may try setting up devicewith a really large number of slots, which causes memory allocationfailure in input_mt_init_slots(). While this allocation failure ishandled properly and request is rejected, it results in syzkallerreports. Additionally, such request may put undue burden on thesystem which will try to free a lot of memory for a bogus request.Fix it by limiting allowed number of slots to 100. This can easilybe extended if we see devices that can track more than 100 contacts.

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 repro calls connect() to vxcan1, removes vxcan1, and callsconnect() with ifindex == 0.Calling connect() for a BCM socket allocates a proc entry.Then, bcm_sk(sk)->bound is set to 1 to prevent further connect().However, removing the bound device resets bcm_sk(sk)->bound to 0in bcm_notify().The 2nd connect() tries to allocate a proc entry with the samename and sets NULL to bcm_sk(sk)->bcm_proc_read, leaking theoriginal proc entry.Since the proc entry is available only for connect()ed sockets,let's clean up the entry when the bound netdev is unregistered.[0]:proc_dir_entry 'can-bcm/2456' already registeredWARNING: CPU: 1 PID: 394 at fs/proc/generic.c:376 proc_register+0x645/0x8f0 fs/proc/generic.c:375Modules linked in:CPU: 1 PID: 394 Comm: syz-executor403 Not tainted 6.10.0-rc7-g852e42cc2dd4Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014RIP: 0010:proc_register+0x645/0x8f0 fs/proc/generic.c:375Code: 00 00 00 00 00 48 85 ed 0f 85 97 02 00 00 4d 85 f6 0f 85 9f 02 00 00 48 c7 c7 9b cb cf 87 48 89 de 4c 89 fa e8 1c 6f eb fe 90 <0f> 0b 90 90 48 c7 c7 98 37 99 89 e8 cb 7e 22 05 bb 00 00 00 10 48RSP: 0018:ffa0000000cd7c30 EFLAGS: 00010246RAX: 9e129be1950f0200 RBX: ff1100011b51582c RCX: ff1100011857cd80RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000002RBP: 0000000000000000 R08: ffd400000000000f R09: ff1100013e78cac0R10: ffac800000cd7980 R11: ff1100013e12b1f0 R12: 0000000000000000R13: 0000000000000000 R14: 0000000000000000 R15: ff1100011a99a2ecFS: 00007fbd7086f740(0000) GS:ff1100013fd00000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00000000200071c0 CR3: 0000000118556004 CR4: 0000000000771ef0DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000DR3: 0000000000000000 DR6: 00000000fffe07f0 DR7: 0000000000000400PKRU: 55555554Call Trace: proc_create_net_single+0x144/0x210 fs/proc/proc_net.c:220 bcm_connect+0x472/0x840 net/can/bcm.c:1673 __sys_connect_file net/socket.c:2049 [inline] __sys_connect+0x5d2/0x690 net/socket.c:2066 __do_sys_connect net/socket.c:2076 [inline] __se_sys_connect net/socket.c:2073 [inline] __x64_sys_connect+0x8f/0x100 net/socket.c:2073 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xd9/0x1c0 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x4b/0x53RIP: 0033:0x7fbd708b0e5dCode: ff c3 66 2e 0f 1f 84 00 00 00 00 00 90 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 8b 0d 73 9f 1b 00 f7 d8 64 89 01 48RSP: 002b:00007fff8cd33f08 EFLAGS: 00000246 ORIG_RAX: 000000000000002aRAX: ffffffffffffffda RBX: 0000000000000003 RCX: 00007fbd708b0e5dRDX: 0000000000000010 RSI: 0000000020000040 RDI: 0000000000000003RBP: 0000000000000000 R08: 0000000000000040 R09: 0000000000000040R10: 0000000000000040 R11: 0000000000000246 R12: 00007fff8cd34098R13: 0000000000401280 R14: 0000000000406de8 R15: 00007fbd70ab9000 remove_proc_entry: removing non-empty directory 'net/can-bcm', leaking at least '2456'

CVE-2024-46787 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:userfaultfd: fix checks for huge PMDsPatch series "userfaultfd: fix races around pmd_trans_huge() check", v2.The pmd_trans_huge() code in mfill_atomic() is wrong in three differentways depending on kernel version:1. The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit the right two race windows) - I've tested this in a kernel build with some extra mdelay() calls. See the commit message for a description of the race scenario. On older kernels (before 6.5), I think the same bug can even theoretically lead to accessing transhuge page contents as a page table if you hit the right 5 narrow race windows (I haven't tested this case).2. As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for detecting PMDs that don't point to page tables. On older kernels (before 6.5), you'd just have to win a single fairly wide race to hit this. I've tested this on 6.1 stable by racing migration (with a mdelay() patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86 VM, that causes a kernel oops in ptlock_ptr().3. On newer kernels (>=6.5), for shmem mappings, khugepaged is allowed to yank page tables out from under us (though I haven't tested that), so I think the BUG_ON() checks in mfill_atomic() are just wrong.I decided to write two separate fixes for these (one fix for bugs 1+2, onefix for bug 3), so that the first fix can be backported to kernelsaffected by bugs 1+2.This patch (of 2):This fixes two issues.I discovered that the following race can occur: mfill_atomic other thread ============ ============ pmdp_get_lockless() [reads none pmd] __pte_alloc [no-op] BUG_ON(pmd_none(*dst_pmd))I have experimentally verified this in a kernel with extra mdelay() calls;the BUG_ON(pmd_none(*dst_pmd)) triggers.On kernels newer than commit 0d940a9b270b ("mm/pgtable: allowpte_offset_map[_lock]() to fail"), this can't lead to anything worse thana BUG_ON(), since the page table access helpers are actually designed todeal with page tables concurrently disappearing; but on older kernels(<=6.4), I think we could probably theoretically race past the twoBUG_ON() checks and end up treating a hugepage as a page table.The second issue is that, as Qi Zheng pointed out, there are other typesof huge PMDs that pmd_trans_huge() can't catch: devmap PMDs and swap PMDs(in particular, migration PMDs).On <=6.4, this is worse than the first issue: If mfill_atomic() runs on aPMD that contains a migration entry (which just requires winning a single,fairly wide race), it will pass the PMD to pte_offset_map_lock(), whichassumes that the PMD points to a page table.Breakage follows: First, the kernel tries to take the PTE lock (which willcrash or maybe worse if there is no "struct page" for the address bits inthe migration entry PMD - I think at least on X86 there usually is nocorresponding "struct page" thanks to the PTE inversion mitigation, amd64looks different).If that didn't crash, the kernel would next try to write a PTE into whatit wrongly thinks is a page table.As part of fixing these issues, get rid of the check for pmd_trans_huge()before __pte_alloc() - that's redundant, we're going to have to check forthat after the __pte_alloc() anyway.Backport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.

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.

(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.

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.

CVE-2024-49881 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: update orig_path in ext4_find_extent()In ext4_find_extent(), if the path is not big enough, we free it and set*orig_path to NULL. 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.

CVE-2024-49938 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmitSyzbot points out that skb_trim() has a sanity check on the existing length ofthe skb, which can be uninitialised in some error paths. The intent here isclearly just to reset the length to zero before resubmitting, so switch tocalling __skb_set_length(skb, 0) directly. In addition, __skb_set_length()already contains a call to skb_reset_tail_pointer(), so remove the redundantcall.The syzbot report came from ath9k_hif_usb_reg_in_cb(), but there's a similarusage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we're at it.

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---

Upon troubleshooting,the fsck -fn output showed the below corruption[EXTENT_LIST_FREE] Extent list in owner 33080590 claims 230 as the next free chain record,but fsck believes the largest valid value is 227. Clamp the next record value? nThe stat output from the debugfs.ocfs2 showed the following corruptionwhere the "Next Free Rec:" had overshot the "Count:" in the root metadatablock.

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.

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---

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.

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.

CVE-2024-50106 Severity: Moderate CVSS3 score: 5.5

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.

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.

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-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-2025-38614 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: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-2025-39684 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:bpf: Forget ranges when refining tnum after JSETSyzbot reported a kernel warning due to a range invariant violation onthe following BPF program. 0: call bpf_get_netns_cookie 1: if r0 == 0 goto 2: if r0 & Oxffffffff goto The issue is on the path where we fall through both jumps.That path is unreachable at runtime: after insn 1, we know r0 != 0, butwith the sign extension on the jset, we would only fallthrough insn 2if r0 == 0. Unfortunately, is_branch_taken() isn't currently able tofigure this out, so the verifier walks all branches. The verifier thenrefines the register bounds using the second condition and we endup with inconsistent bounds on this unreachable path: 1: if r0 == 0 goto r0: u64=[0x1, 0xffffffffffffffff] var_off=(0, 0xffffffffffffffff) 2: if r0 & 0xffffffff goto r0 before reg_bounds_sync: u64=[0x1, 0xffffffffffffffff] var_off=(0, 0) r0 after reg_bounds_sync: u64=[0x1, 0] var_off=(0, 0)Improving the range refinement for JSET to cover all cases is tricky. Wealso don't expect many users to rely on JSET given LLVM doesn't generatethose instructions. So instead of improving the range refinement forJSETs, Eduard suggested we forget the ranges whenever we're narrowingtnums after a JSET. This patch implements that approach.

CVE-2025-39913 Severity: Moderate CVSS3 score: 5.5

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

Description: In the Linux kernel, the following vulnerability has been resolved:net: rfkill: gpio: Fix crash due to dereferencering uninitialized pointerSince commit 7d5e9737efda ("net: rfkill: gpio: get the name and type fromdevice property") rfkill_find_type() gets called with the possiblyuninitialized "const char *type_name;" local variable.On x86 systems when rfkill-gpio binds to a "BCM4752" or "LNV4752"acpi_device, the rfkill->type is set based on the ACPI acpi_device_id: rfkill->type = (unsigned)id->driver_data;and there is no "type" property so device_property_read_string() will failand leave type_name uninitialized, leading to a potential crash.rfkill_find_type() does accept a NULL pointer, fix the potential crashby initializing type_name to NULL.Note likely sofar this has not been caught because:1. Not many x86 machines actually have a "BCM4752"/"LNV4752" acpi_device2. The stack happened to contain NULL where type_name is stored

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-2025-40106 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: fix divide-by-zero in comedi_buf_munge()The comedi_buf_munge() function performs a modulo operation`async->munge_chan %= async->cmd.chanlist_len` without firstchecking if chanlist_len is zero. If a user program submits a command withchanlist_len set to zero, this causes a divide-by-zero error when the deviceprocesses data in the interrupt handler path.Add a check for zero chanlist_len at the beginning of thefunction, similar to the existing checks for !map andCMDF_RAWDATA flag. When chanlist_len is zero, updatemunge_count and return early, indicating the data washandled without munging.This prevents potential kernel panics from malformed user commands.

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.

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:net: qlogic/qede: fix potential out-of-bounds read in qede_tpa_cont() and qede_tpa_end()The loops in 'qede_tpa_cont()' and 'qede_tpa_end()', iterateover 'cqe->len_list[]' using only a zero-length terminator asthe stopping condition. If the terminator was missing ormalformed, the loop could run past the end of the fixed-size array.Add an explicit bound check using ARRAY_SIZE() in both loops to preventa potential out-of-bounds access.Found by Linux Verification Center (linuxtesting.org) with SVACE.

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).

CVE-2025-40269 Severity: Moderate CVSS3 score: 5.5

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].

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: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.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: brcmfmac: fix crash while sending Action Frames in standalone AP ModeCurrently, whenever there is a need to transmit an Action frame,the brcmfmac driver always uses the P2P vif to send the "actframe" IOVAR tofirmware.

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.

CVE-2025-40341 Severity: Moderate CVSS3 score: 5.5

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.

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.

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.

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.

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.

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: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.

CVE-2025-68358 Severity: Moderate CVSS3 score: 5.5

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---

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.

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:Input: alps - fix use-after-free bugs caused by dev3_register_workThe dev3_register_work delayed work item is initialized withinalps_reconnect() and scheduled upon receipt of the first barePS/2 packet from an external PS/2 device connected to the ALPStouchpad. 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.

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:functionfs: fix the open/removal racesffs_epfile_open() can race with removal, ending up with file->private_datapointing to freed object.There is a total count of opened files on functionfs (both ep0 anddynamic ones) and when it hits zero, dynamic files get removed.Unfortunately, that removal can happen while another thread isin ffs_epfile_open(), but has not incremented the count yet.In that case open will succeed, leaving us with UAF on any subsequentread() or write().The root cause is that ffs->opened is misused; atomic_dec_and_test() vs.atomic_add_return() is not a good idea, when object remains visible allalong.To untangle that * serialize openers on ffs->mutex (both for ep0 and for dynamic files) * have dynamic ones use atomic_inc_not_zero() and fail if we hadzero ->opened; in that case the file we are opening is doomed. * have the inodes of dynamic files marked on removal (from thecallback of simple_recursive_removal()) - clear ->i_private there. * have open of dynamic ones verify they hadn't been already removed,along with checking that state is FFS_ACTIVE.

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: btusb: revert use of devm_kzalloc in btusbThis reverts commit 98921dbd00c4e ("Bluetooth: Use devm_kzalloc inbtusb.c file").In btusb_probe(), we use devm_kzalloc() to allocate the btusb data. Thisties the lifetime of all the btusb data to the binding of a driver toone interface, INTF. In a driver that binds to other interfaces, ISOCand DIAG, this is an accident waiting to happen.The issue is revealed in btusb_disconnect(), where callingusb_driver_release_interface(&btusb_driver, data->intf) will have devmfree the data that is also being used by the other interfaces of thedriver that may not be released yet.To fix this, revert the use of devm and go back to freeing memoryexplicitly.

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

CVE-2025-71183 Severity: Moderate CVSS3 score: 5.5

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 (...)

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.

If you're using a Python version that implements PEP 706then pip doesn't use the "vulnerable" fallback code.Mitigations include upgrading to a version of pip that includes the fix, upgrading to a Python version that implements PEP 706 (Python >=3.9.17, >=3.10.12, >=3.11.4, or >=3.12),applying the linked patch, or inspecting source distributions (sdists) before installation as is already a best-practice.

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: sch_qfq: Fix NULL deref when deactivating inactive aggregate in qfq_reset`qfq_class->leaf_qdisc->q.qlen > 0` does not imply that the classitself is active.Two qfq_class objects may point to the same leaf_qdisc. 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---

CVE-2026-22991 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:libceph: make free_choose_arg_map() resilient to partial allocationfree_choose_arg_map() may dereference a NULL pointer if its caller failsafter a partial allocation.For example, in decode_choose_args(), if allocation of arg_map->argsfails, execution jumps to the fail label and free_choose_arg_map() iscalled. Since arg_map->size is updated to a non-zero value before memoryallocation, free_choose_arg_map() will iterate over arg_map->args anddereference a NULL pointer.To prevent this potential NULL pointer dereference and makefree_choose_arg_map() more resilient, add checks for pointers beforeiterating.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:can: esd_usb: esd_usb_read_bulk_callback(): fix URB memory leakFix similar memory leak as in commit 7352e1d5932a ("can: gs_usb:gs_usb_receive_bulk_callback(): fix URB memory leak").In esd_usb_open(), the URBs for USB-in transfers are allocated, added tothe dev->rx_submitted anchor and submitted. 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.

CVE-2026-23085 Severity: Moderate CVSS3 score: 5.5

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.

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.

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.

CVE-2026-23318 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-audio: Use correct version for UAC3 header validationThe entry of the validators table for UAC3 AC header descriptor isdefined with the wrong protocol version UAC_VERSION_2, while it shouldhave been UAC_VERSION_3. This results in the validator never matchingfor actual UAC3 devices (protocol == UAC_VERSION_3), causing theirheader descriptors to bypass validation entirely. A malicious USBdevice presenting a truncated UAC3 header could exploit this to causeout-of-bounds reads when the driver later accesses unvalidateddescriptor fields.The bug was introduced in the same commit as the recently fixed UAC3feature unit sub-type typo, and appears to be from the same copy-pasteerror when the UAC3 section was created from the UAC2 section.

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.

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-2026-31411 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:netfilter: nf_conntrack_expect: use expect->helperUse expect->helper in ctnetlink and /proc to dump the helper name.Using nfct_help() without holding a reference to the master conntrackis unsafe.Use exp->master->helper in ctnetlink path if userspace does not providean explicit helper when creating an expectation to retain the existingbehaviour. The ctnetlink expectation path holds the reference on themaster conntrack and nf_conntrack_expect lock and the nfnetlink gluepath refers to the master ct that is attached to the skb.

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. When sendmsg() withRDS_CMSG_RDMA_MAP is called on such a connection, the sendmsg path parsesthe control message before any connection establishment, allowingrds_ib_post_reg_frmr() to dereference ic->i_cm_id->qp and crash thekernel.The existing guard in rds_ib_reg_frmr() only checks for !ic (added incommit 9e630bcb7701), which does not catch this case since ic is allocatedearly and is always non-NULL once the connection object exists.

Description: OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, an integer underflow vulnerability in _ppdCreateFromIPP() (cups/ppd-cache.c) allows any unprivileged local user to crash the cupsd root process by supplying a negative job-password-supported IPP attribute. The bounds check only caps the upper bound, so a negative value passes validation, is cast to size_t (wrapping to ~2^64), and is used as the length argument to memset() on a 33-byte stack buffer. This causes an immediate SIGSEGV in the cupsd root process. Combined with systemd's Restart=on-failure, an attacker can repeat the crash for sustained denial of service.

Description: OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, a use-after-free vulnerability exists in the CUPS scheduler (cupsd) when temporary printers are automatically deleted. cupsdDeleteTemporaryPrinters() in scheduler/printers.c calls cupsdDeletePrinter() without first expiring subscriptions that reference the printer, leaving cupsd_subscription_t.dest as a dangling pointer to freed heap memory. The dangling pointer is subsequently dereferenced at multiple code sites, causing a crash (denial of service) of the cupsd daemon. With heap grooming, this can be leveraged for code execution.

CVE-2026-4897 Severity: Moderate CVSS3 score: 5.5

Description: A flaw was found in polkit. A local user can exploit this by providing a specially crafted, excessively long input to the `polkit-agent-helper-1` setuid binary via standard input (stdin). This unbounded input can lead to an out-of-memory (OOM) condition, resulting in a Denial of Service (DoS) for the system.

CVE-2026-6862 Severity: Moderate CVSS3 score: 5.5

Description: A flaw was found in libefiboot, a component of efivar. The device path node parser in libefiboot fails to validate that each node's Length field is at least 4 bytes, which is the minimum size for an EFI (Extensible Firmware Interface) device path node header. A local user could exploit this vulnerability by providing a specially crafted device path node. This can lead to infinite recursion, causing stack exhaustion and a process crash, resulting in a denial of service (DoS).

Description: Jinja is an extensible templating engine. Special placeholders in the template allow writing code similar to Python syntax. It is possible to inject arbitrary HTML attributes into the rendered HTML template, potentially leading to Cross-Site Scripting (XSS). The Jinja `xmlattr` filter can be abused to inject arbitrary HTML attribute keys and values, bypassing the auto escaping mechanism and potentially leading to XSS. It may also be possible to bypass attribute validation checks if they are blacklist-based.

CVE-2024-12243 Severity: Moderate CVSS3 score: 5.3

Description: A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition.

CVE-2024-9681 Severity: Moderate CVSS3 score: 5.3

Description: When curl is asked to use HSTS, the expiry time for a subdomain mightoverwrite a parent domain's cache entry, making it end sooner or later thanotherwise intended.This affects curl using applications that enable HSTS and use URLs with theinsecure `HTTP://` scheme and perform transfers with hosts like`x.example.com` as well as `example.com` where the first host is a subdomainof the second host.(The HSTS cache either needs to have been populated manually or there needs tohave been previous HTTPS accesses done as the cache needs to have entries forthe domains involved to trigger this problem.)When `x.example.com` responds with `Strict-Transport-Security:` headers, thisbug can make the subdomain's expiry timeout *bleed over* and get set for theparent domain `example.com` in curl's HSTS cache.The result of a triggered bug is that HTTP accesses to `example.com` getconverted to HTTPS for a different period of time than what was asked for bythe origin server. If `example.com` for example stops supporting HTTPS at itsexpiry time, curl might then fail to access `http://example.com` until the(wrongly set) timeout expires. This bug can also expire the parent's entry*earlier*, thus making curl inadvertently switch back to insecure HTTP earlierthan otherwise intended.

CVE-2025-24294 Severity: Moderate CVSS3 score: 5.3

Description: The attack vector is a potential Denial of Service (DoS). The vulnerability is caused by an insufficient check on the length of a decompressed domain name within a DNS packet.An attacker can craft a malicious DNS packet containing a highly compressed domain name. When the resolv library parses such a packet, the name decompression process consumes a large amount of CPU resources, as the library does not limit the resulting length of the name.This resource consumption can cause the application thread to become unresponsive, resulting in a Denial of Service condition.

CVE-2025-58058 Severity: Moderate CVSS3 score: 5.3

Description: xz is a pure golang package for reading and writing xz-compressed files. Prior to version 0.5.14, it is possible to put data in front of an LZMA-encoded byte stream without detecting the situation while reading the header. This can lead to increased memory consumption because the current implementation allocates the full decoding buffer directly after reading the header. The LZMA header doesn't include a magic number or has a checksum to detect such an issue according to the specification. Note that the code recognizes the issue later while reading the stream, but at this time the memory allocation has already been done. This issue has been patched in version 0.5.14.

Description: urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.24 and prior to 2.6.0, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps leading to high CPU usage and massive memory allocation for the decompressed data.

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: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.

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-2026-34757 Severity: Moderate CVSS3 score: 5.1

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.

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

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-2025-4598 Severity: Moderate CVSS3 score: 4.7

Description: A vulnerability was found in systemd-coredump. This flaw allows an attacker to force a SUID process to crash and replace it with a non-SUID binary to access the original's privileged process coredump, allowing the attacker to read sensitive data, such as /etc/shadow content, loaded by the original process.A SUID binary or process has a special type of permission, which allows the process to run with the file owner's permissions, regardless of the user executing the binary. This allows the process to access more restricted data than unprivileged users or processes would be able to. An attacker can leverage this flaw by forcing a SUID process to crash and force the Linux kernel to recycle the process PID before systemd-coredump can analyze the /proc/pid/auxv file. If the attacker wins the race condition, they gain access to the original's SUID process coredump file. They can read sensitive content loaded into memory by the original binary, affecting data confidentiality.

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().

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.

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.

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-2024-43790 Severity: Moderate CVSS3 score: 4.5

Description: Vim is an open source command line text editor. When performing a search and displaying the search-count message is disabled (:set shm+=S), the search pattern is displayed at the bottom of the screen in a buffer (msgbuf). When right-left mode (:set rl) is enabled, the search pattern is reversed. This happens by allocating a new buffer. If the search pattern contains some ASCII NUL characters, the buffer allocated will be smaller than the original allocated buffer (because for allocating the reversed buffer, the strlen() function is called, which only counts until it notices an ASCII NUL byte ) and thus the original length indicator is wrong. This causes an overflow when accessing characters inside the msgbuf by the previously (now wrong) length of the msgbuf. The issue has been fixed as of Vim patch v9.1.0689.

CVE-2024-43802 Severity: Moderate CVSS3 score: 4.5

Description: Vim is an improved version of the unix vi text editor. When flushing the typeahead buffer, Vim moves the current position in the typeahead buffer but does not check whether there is enough space left in the buffer to handle the next characters. So this may lead to the tb_off position within the typebuf variable to point outside of the valid buffer size, which can then later lead to a heap-buffer overflow in e.g. ins_typebuf(). Therefore, when flushing the typeahead buffer, check if there is enough space left before advancing the off position. If not, fall back to flush current typebuf contents. It's not quite clear yet, what can lead to this situation. It seems to happen when error messages occur (which will cause Vim to flush the typeahead buffer) in comnination with several long mappgins and so it may eventually move the off position out of a valid buffer size. Impact is low since it is not easily reproducible and requires to have several mappings active and run into some error condition. But when this happens, this will cause a crash. The issue has been fixed as of Vim patch v9.1.0697. Users are advised to upgrade. There are no known workarounds for this issue.

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.

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.

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-2024-45306 Severity: Moderate CVSS3 score: 4.4

Description: Vim is an open source, command line text editor. Patch v9.1.0038 optimized how the cursor position is calculated and removed a loop, that verified that the cursor position always points inside a line and does not become invalid by pointing beyond the end ofa line. Back then we assumed this loop is unnecessary. However, this change made it possible that the cursor position stays invalid and points beyond the end of a line, which would eventually cause a heap-buffer-overflow when trying to access the line pointer atthe specified cursor position. It's not quite clear yet, what can lead to this situation that the cursor points to an invalid position. That's why patch v9.1.0707 does not include a test case. The only observed impact has been a program crash. This issue has been addressed in with the patch v9.1.0707. All users are advised to upgrade.

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: 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()").

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.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:be2net: Fix NULL pointer dereference in be_cmd_get_mac_from_listWhen the parameter pmac_id_valid argument of be_cmd_get_mac_from_list() isset to false, the driver may request the PMAC_ID from the firmware of thenetwork card, and this function will store that PMAC_ID at the providedaddress pmac_id. This is the contract of this function.However, there is a location within the driver where bothpmac_id_valid == false and pmac_id == NULL are being passed. This couldresult in dereferencing a NULL pointer.To resolve this issue, it is necessary to pass the address of a stubvariable to the function.

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. When building the final skb, the actual push length comes from `dst1opt` and is not limited by wrapped `opt_flen`: - In `net/ipv6/ip6_output.c:1930-1934`: - `if (opt->opt_flen) proto = ipv6_push_frag_opts(skb, opt, proto);` - In `net/ipv6/exthdrs.c:1206-1211`, `ipv6_push_frag_opts()` pushes `dst1opt` via `ipv6_push_exthdr()`. - In `net/ipv6/exthdrs.c:1179-1184`, `ipv6_push_exthdr()` does: - `skb_push(skb, ipv6_optlen(opt));` - `memcpy(h, opt, ipv6_optlen(opt));` With insufficient headroom, `skb_push()` underflows and triggers `skb_under_panic()` -> `BUG()`: - `net/core/skbuff.c:2669-2675` (`skb_push()` calls `skb_under_panic()`) - `net/core/skbuff.c:207-214` (`skb_panic()` ends in `BUG()`) - The `IPV6_DSTOPTS` cmsg path requires `CAP_NET_RAW` in the target netns user namespace (`ns_capable(net->user_ns, CAP_NET_RAW)`). - Root (or any task with `CAP_NET_RAW`) can trigger this without user namespaces. - An unprivileged `uid=1000` user can trigger this if unprivileged user namespaces are enabled and it can create a userns+netns to obtain namespaced `CAP_NET_RAW` (the attached PoC does this). - Local denial of service: kernel BUG/panic (system crash). ----truncated---

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-2024-35221 Severity: Moderate CVSS3 score: 4.3

Description: Rubygems.org is the Ruby community's gem hosting service. A Gem publisher can cause a Remote DoS when publishing a Gem. This is due to how Ruby reads the Manifest of Gem files when using Gem::Specification.from_yaml. from_yaml makes use of SafeYAML.load which allows YAML aliases inside the YAML-based metadata of a gem. YAML aliases allow for Denial of Service attacks with so-called `YAML-bombs` (comparable to Billion laughs attacks). This was patched. There is is no action required by users. This issue is also tracked as GHSL-2024-001 and was discovered by the GitHub security lab.

Description: In the Linux kernel, the following vulnerability has been resolved:nfc: pn533: Add poll mod list filling checkIn case of im_protocols value is 1 and tm_protocols value is 0 thiscombination successfully passes the check'if (!im_protocols && !tm_protocols)' in the nfc_start_poll().But then after pn533_poll_create_mod_list() call in pn533_start_poll()poll mod list will remain empty and dev->poll_mod_count will remain 0which lead to division by zero.Normally no im protocol has value 1 in the mask, so this combination isnot expected by driver. But these protocol values actually come fromuserspace via Netlink interface (NFC_CMD_START_POLL operation). So abroken or malicious program may pass a message containing a "bad"combination of protocol parameter values so that dev->poll_mod_countis not incremented inside pn533_poll_create_mod_list(), thus leadingto division by zero.Call trace looks like:nfc_genl_start_poll() nfc_start_poll() ->start_poll() pn533_start_poll()Add poll mod list filling check.Found by Linux Verification Center (linuxtesting.org) with SVACE.

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.

If thepayload is too short, skip the read and let the state machine completewith safe defaults (feat_mask and remote_fixed_chan remain zero fromkzalloc), so the info timer cleanup and l2cap_conn_start() still runand the connection is not stalled.

CVE-2025-22134 Severity: Moderate CVSS3 score: 4.2

Description: When switching to other buffers using the :all command and visual mode still being active, this may cause a heap-buffer overflow, because Vim does not properly end visual mode and therefore may try to access beyond the end of a line in a buffer. In Patch 9.1.1003 Vim will correctly reset the visual mode before opening other windows and buffers and therefore fix this bug. In addition it does verify that it won't try to access a position if the position is greater than the corresponding buffer line. Impact is medium since the user must have switched on visual mode when executing the :all ex command. The Vim project would like to thank github user gandalf4a for reporting this issue. The issue has been fixed as of Vim patch v9.1.1003

Description: Vim is an open source, command line text editor. A segmentation fault was found in Vim before 9.1.1043. In silent Ex mode (-s -e), Vim typically doesn't show a screen and just operates silently in batch mode. However, it is still possible to trigger the function that handles the scrolling of a gui version of Vim by feeding some binary characters to Vim. The function that handles the scrolling however may be triggering a redraw, which will access the ScreenLines pointer, even so this variable hasn't been allocated (since there is no screen). This vulnerability is fixed in 9.1.1043.

CVE-2022-48734 Severity: Moderate CVSS3 score: 4.1

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix deadlock between quota disable and qgroup rescan workerQuota disable ioctl starts a transaction before waiting for the qgrouprescan worker completes. However, this wait can be infinite and resultsin deadlock because of circular dependency among the quota disableioctl, the qgroup rescan worker and the other task with transaction suchas block group relocation task.The deadlock happens with the steps following:1) Task A calls ioctl to disable quota. It starts a transaction and waits for qgroup rescan worker completes.2) Task B such as block group relocation task starts a transaction and joins to the transaction that task A started. Then task B commits to the transaction. In this commit, task B waits for a commit by task A.3) Task C as the qgroup rescan worker starts its job and starts a transaction. In this transaction start, task C waits for completion of the transaction that task A started and task B committed.This deadlock was found with fstests test case btrfs/115 and a zonednull_blk device. The test case enables and disables quota, and theblock group reclaim was triggered during the quota disable by chance.The deadlock was also observed by running quota enable and disable inparallel with 'btrfs balance' command on regular null_blk devices.An example report of the deadlock: [372.469894] INFO: task kworker/u16:6:103 blocked for more than 122 seconds.

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.

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-2025-71079 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.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: core: Fix unremoved procfs host directory regressionCommit fc663711b944 ("scsi: core: Remove the /proc/scsi/${proc_name}directory earlier") fixed a bug related to modules loading/unloading, byadding a call to scsi_proc_hostdir_rm() on scsi_remove_host(). But that ledto a potential duplicate call to the hostdir_rm() routine, since it's alsocalled from scsi_host_dev_release(). That triggered a regression report,which was then fixed by commit be03df3d4bfe ("scsi: core: Fix a procfs hostdirectory removal regression"). The fix just dropped the hostdir_rm() callfrom dev_release().But it happens that this proc directory is created on scsi_host_alloc(),and that function "pairs" with scsi_host_dev_release(), whilescsi_remove_host() pairs with scsi_add_host(). In other words, it seems thereason for removing the proc directory on dev_release() was meant to covercases in which a SCSI host structure was allocated, but the call toscsi_add_host() didn't happen. And that pattern happens to exist in someerror paths, for example.Syzkaller causes that by using USB raw gadget device, error'ing onusb-storage driver, at usb_stor_probe2(). By checking that path, we can seethat the BadDevice label leads to a scsi_host_put() after a SCSI hostallocation, but there's no call to scsi_add_host() in such path. That leadsto messages like this in dmesg (and a leak of the SCSI host procstructure):usb-storage 4-1:87.51: USB Mass Storage device detectedproc_dir_entry 'scsi/usb-storage' already registeredWARNING: CPU: 1 PID: 3519 at fs/proc/generic.c:377 proc_register+0x347/0x4e0 fs/proc/generic.c:376The proper fix seems to still call scsi_proc_hostdir_rm() on dev_release(),but guard that with the state check for SHOST_CREATED; there is even acomment in scsi_host_dev_release() detailing that: such conditional ismeant for cases where the SCSI host was allocated but there was no calls to{add,remove}_host(), like the usb-storage case.This is what we propose here and with that, the error path of usb-storagedoes not trigger the warning anymore.

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.

CVE-2024-43374 Severity: Moderate CVSS3 score: 3.3

Description: The UNIX editor Vim prior to version 9.1.0678 has a use-after-free error in argument list handling. When adding a new file to the argument list, this triggers `Buf*` autocommands. If in such an autocommand the buffer that was just opened is closed (including the window where it is shown), this causes the window structure to be freed which contains a reference to the argument list that we are actually modifying. Once the autocommands are completed, the references to the window and argument list are no longer valid and as such cause an use-after-free. Impact is low since the user must either intentionally add some unusual autocommands that wipe a buffer during creation (either manually or by sourcing a malicious plugin), but it will crash Vim. The issue has been fixed as of Vim patch v9.1.0678.

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.

Description: A flaw was found in Glib's content type parsing logic. This buffer underflow vulnerability occurs because the length of a header line is stored in a signed integer, which can lead to integer wraparound for very large inputs. This results in pointer underflow and out-of-bounds memory access. Exploitation requires a local user to install or process a specially crafted treemagic file, which can lead to local denial of service or application instability.

Description: A flaw was identified in the interactive shell of the xmllint utility, part of the libxml2 project, where memory allocated for user input is not properly released under certain conditions. When a user submits input consisting only of whitespace, the program skips command execution but fails to free the allocated buffer. Repeating this action causes memory to continuously accumulate. Over time, this can exhaust system memory and terminate the xmllint process, creating a denial-of-service condition on the local system.

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.

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.

For example, the igb_io_error_detectedtriggers the first call, and the igb_remove triggers the second call.The second call to igb_down will block at napi_synchronize.Here's the call trace: __schedule+0x3b0/0xddb ? __mod_timer+0x164/0x5d3 schedule+0x44/0xa8 schedule_timeout+0xb2/0x2a4 ? run_local_timers+0x4e/0x4e msleep+0x31/0x38 igb_down+0x12c/0x22a [igb 6615058754948bfde0bf01429257eb59f13030d4] __igb_close+0x6f/0x9c [igb 6615058754948bfde0bf01429257eb59f13030d4] igb_close+0x23/0x2b [igb 6615058754948bfde0bf01429257eb59f13030d4] __dev_close_many+0x95/0xec dev_close_many+0x6e/0x103 unregister_netdevice_many+0x105/0x5b1 unregister_netdevice_queue+0xc2/0x10d unregister_netdev+0x1c/0x23 igb_remove+0xa7/0x11c [igb 6615058754948bfde0bf01429257eb59f13030d4] pci_device_remove+0x3f/0x9c device_release_driver_internal+0xfe/0x1b4 pci_stop_bus_device+0x5b/0x7f pci_stop_bus_device+0x30/0x7f pci_stop_bus_device+0x30/0x7f pci_stop_and_remove_bus_device+0x12/0x19 pciehp_unconfigure_device+0x76/0xe9 pciehp_disable_slot+0x6e/0x131 pciehp_handle_presence_or_link_change+0x7a/0x3f7 pciehp_ist+0xbe/0x194 irq_thread_fn+0x22/0x4d ? irq_thread+0x1fd/0x1fd irq_thread+0x17b/0x1fd ? irq_forced_thread_fn+0x5f/0x5f kthread+0x142/0x153 ? __irq_get_irqchip_state+0x46/0x46 ? kthread_associate_blkcg+0x71/0x71 ret_from_fork+0x1f/0x30In this case, igb_io_error_detected detaches the network interfaceand requests a PCIE slot reset, however, the PCIE reset callback isnot being invoked and thus the Ethernet connection breaks down.As the PCIE error in this case is a non-fatal one, requesting aslot reset can be avoided.This patch fixes the task hung issue and preserves Ethernetconnection by ignoring non-fatal PCIE errors.

Description: In the Linux kernel, the following vulnerability has been resolved:af_unix: Fix data races in unix_release_sock/unix_stream_sendmsgA data-race condition has been identified in af_unix. In one data path,the write function unix_release_sock() atomically writes tosk->sk_shutdown using WRITE_ONCE. However, on the reader side,unix_stream_sendmsg() does not read it atomically. 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

Thelatter was then reverted by commit ebc69e897e17 ("Revert "block, bfq:honor already-setup queue merges""). Yet, the reverted commit was notthe one introducing the bug. In fact, it actually triggered a UAFintroduced by a different commit, and now fixed by commit d29bd41428cf("block, bfq: reset last_bfqq_created on group change").So, there is no point in keeping commit 2d52c58b9c9b ("block, bfq:honor already-setup queue merges") out.

CVE-2024-41007 Severity: Low CVSS3 score: 2.5

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.

CVE-2024-47660 Severity: Low CVSS3 score: 2.5

Description: In the Linux kernel, the following vulnerability has been resolved:fsnotify: clear PARENT_WATCHED flags lazilyIn some setups directories can have many (usually negative) dentries.Hence __fsnotify_update_child_dentry_flags() function can take asignificant amount of time. 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.

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.

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.

Description: A flaw was found in libssh. A remote attacker, by controlling client configuration files or known_hosts files, could craft specific hostnames that when processed by the `match_pattern()` function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion, resulting in a Denial of Service (DoS) for the client.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:qed: allow sleep in qed_mcp_trace_dump()By default, qed_mcp_cmd_and_union() delays 10us at a time in a loopthat can run 500K times, so calls to qed_mcp_nvm_rd_cmd()may block the current thread for over 5s.We observed thread scheduling delays over 700ms in production,with stacktraces pointing to this code as the culprit.qed_mcp_trace_dump() is called from ethtool, so sleeping is permitted.It already can sleep in qed_mcp_halt(), which calls qed_mcp_cmd().Add a "can sleep" parameter to qed_find_nvram_image() andqed_nvram_read() so they can sleep during qed_mcp_trace_dump().qed_mcp_trace_get_meta_info() and qed_mcp_trace_read_meta(),called only by qed_mcp_trace_dump(), allow these functions to sleep.I can't tell if the other caller (qed_grc_dump_mcp_hw_dump()) can sleep,so keep b_can_sleep set to false when it calls these functions.An example stacktrace from a custom warning we added to the kernelshowing a thread that has not scheduled despite long needing resched:[ 2745.362925,17] ------------[ cut here ]------------[ 2745.362941,17] WARNING: CPU: 23 PID: 5640 at arch/x86/kernel/irq.c:233 do_IRQ+0x15e/0x1a0()[ 2745.362946,17] Thread not rescheduled for 744 ms after irq 99[ 2745.362956,17] Modules linked in: ...[ 2745.363339,17] CPU: 23 PID: 5640 Comm: lldpd Tainted: P O 4.4.182+ #202104120910+6d1da174272d.61x[ 2745.363343,17] Hardware name: FOXCONN MercuryB/Quicksilver Controller, BIOS H11P1N09 07/08/2020[ 2745.363346,17] 0000000000000000 ffff885ec07c3ed8 ffffffff8131eb2f ffff885ec07c3f20[ 2745.363358,17] ffffffff81d14f64 ffff885ec07c3f10 ffffffff81072ac2 ffff88be98ed0000[ 2745.363369,17] 0000000000000063 0000000000000174 0000000000000074 0000000000000000[ 2745.363379,17] Call Trace:[ 2745.363382,17] [] dump_stack+0x8e/0xcf[ 2745.363393,17] [] warn_slowpath_common+0x82/0xc0[ 2745.363398,17] [] warn_slowpath_fmt+0x4c/0x50[ 2745.363404,17] [] ? rcu_irq_exit+0xae/0xc0[ 2745.363408,17] [] do_IRQ+0x15e/0x1a0[ 2745.363413,17] [] common_interrupt+0x89/0x89[ 2745.363416,17] [] ? delay_tsc+0x24/0x50[ 2745.363425,17] [] __udelay+0x34/0x40[ 2745.363457,17] [] qed_mcp_cmd_and_union+0x36f/0x7d0 [qed][ 2745.363473,17] [] qed_mcp_nvm_rd_cmd+0x4d/0x90 [qed][ 2745.363490,17] [] qed_mcp_trace_dump+0x4a7/0x630 [qed][ 2745.363504,17] [] ? qed_fw_asserts_dump+0x1d6/0x1f0 [qed][ 2745.363520,17] [] qed_dbg_mcp_trace_get_dump_buf_size+0x37/0x80 [qed][ 2745.363536,17] [] qed_dbg_feature_size+0x61/0xa0 [qed][ 2745.363551,17] [] qed_dbg_all_data_size+0x247/0x260 [qed][ 2745.363560,17] [] qede_get_regs_len+0x30/0x40 [qede][ 2745.363566,17] [] ethtool_get_drvinfo+0xe3/0x190[ 2745.363570,17] [] dev_ethtool+0x1362/0x2140[ 2745.363575,17] [] ? finish_task_switch+0x76/0x260[ 2745.363580,17] [] ? __schedule+0x3c6/0x9d0[ 2745.363585,17] [] ? hrtimer_start_range_ns+0x1d0/0x370[ 2745.363589,17] [] ? dev_get_by_name_rcu+0x6b/0x90[ 2745.363594,17] [] dev_ioctl+0xe8/0x710[ 2745.363599,17] [] sock_do_ioctl+0x48/0x60[ 2745.363603,17] [] sock_ioctl+0x1c7/0x280[ 2745.363608,17] [] ? seccomp_phase1+0x83/0x220[ 2745.363612,17] [] do_vfs_ioctl+0x2b3/0x4e0[ 2745.363616,17] [] SyS_ioctl+0x41/0x70[ 2745.363619,17] [] entry_SYSCALL_64_fastpath+0x1e/0x79[ 2745.363622,17] ---[ end trace f6954aa440266421 ]---

CVE-2023-54145 Severity: Moderate CVSS3 score: 0.0

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.

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.

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().
