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-2026-33636 Severity: Important CVSS3 score: 8.6

Description: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. In versions 1.6.36 through 1.6.55, an out-of-bounds read and write exists in libpng's ARM/AArch64 Neon-optimized palette expansion path. When expanding 8-bit paletted rows to RGB or RGBA, the Neon loop processes a final partial chunk without verifying that enough input pixels remain. Because the implementation works backward from the end of the row, the final iteration dereferences pointers before the start of the row buffer (OOB read) and writes expanded pixel data to the same underflowed positions (OOB write). This is reachable via normal decoding of attacker-controlled PNG input if Neon is enabled. Version 1.6.56 fixes the issue.

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

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

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

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

CVE-2026-31788 Severity: Important CVSS3 score: 8.2

Description: In the Linux kernel, the following vulnerability has been resolved:xen/privcmd: restrict usage in unprivileged domUThe Xen privcmd driver allows to issue arbitrary hypercalls fromuser space processes. This is normally no problem, as access isusually limited to root and the hypervisor will deny any hypercallsaffecting other domains.In case the guest is booted using secure boot, however, the privcmddriver would be enabling a root user process to modify e.g. kernelmemory contents, thus breaking the secure boot feature.The only known case where an unprivileged domU is really needing touse the privcmd driver is the case when it is acting as the devicemodel for another guest. In this case all hypercalls issued via theprivcmd driver will target that other guest.Fortunately the privcmd driver can already be locked down to allowonly hypercalls targeting a specific domain, but this mode can beactivated from user land only today.The target domain can be obtained from Xenstore, so when not runningin dom0 restrict the privcmd driver to that target domain from thebeginning, resolving the potential problem of breaking secure boot.This is XSA-482---V2:- defer reading from Xenstore if Xenstore isn't ready yet (Jan Beulich)- wait in open() if target domain isn't known yet- issue message in case no target domain found (Jan Beulich)

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

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

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

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

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

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

CVE-2026-41316 Severity: Important CVSS3 score: 8.1

Description: ERB is a templating system for Ruby. Ruby 2.7.0 (before ERB 2.2.0 was published on rubygems.org) introduced an `@_init` instance variable guard in `ERB#result` and `ERB#run` to prevent code execution when an ERB object is reconstructed via `Marshal.load` (deserialization). However, three other public methods that also evaluate `@src` via `eval()` were not given the same guard: `ERB#def_method`, `ERB#def_module`, and `ERB#def_class`. An attacker who can trigger `Marshal.load` on untrusted data in a Ruby application that has `erb` loaded can use `ERB#def_module` (zero-arg, default parameters) as a code execution sink, bypassing the `@_init` protection entirely. ERB 4.0.3.1, 4.0.4.1, 6.0.1.1, and 6.0.4 patch 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-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:media: mediatek: vcodec: fix use-after-free in encoder release pathThe fops_vcodec_release() function frees the context structure (ctx)without first cancelling any pending or running work in ctx->encode_work.This creates a race window where the workqueue handler (mtk_venc_worker)may still be accessing the context memory after it has been freed.Race condition: CPU 0 (release path) CPU 1 (workqueue) --------------------- ------------------ fops_vcodec_release() v4l2_m2m_ctx_release() v4l2_m2m_cancel_job() // waits for m2m job "done" mtk_venc_worker() v4l2_m2m_job_finish() // m2m job "done" // BUT worker still running! // post-job_finish access: other ctx dereferences // UAF if ctx already freed // returns (job "done") kfree(ctx) // ctx freedRoot cause: The v4l2_m2m_ctx_release() only waits for the m2m joblifecycle (via TRANS_RUNNING flag), not the workqueue lifecycle.After v4l2_m2m_job_finish() is called, the m2m framework considersthe job complete and v4l2_m2m_ctx_release() returns, but the workerfunction continues executing and may still access ctx.The work is queued during encode operations via: queue_work(ctx->dev->encode_workqueue, &ctx->encode_work)The worker function accesses ctx->m2m_ctx, ctx->dev, and other ctxfields even after calling v4l2_m2m_job_finish().This vulnerability was confirmed with KASAN by running an instrumentedtest module that widens the post-job_finish race window. KASAN detected: BUG: KASAN: slab-use-after-free in mtk_venc_worker+0x159/0x180 Read of size 4 at addr ffff88800326e000 by task kworker/u8:0/12 Workqueue: mtk_vcodec_enc_wq mtk_venc_worker Allocated by task 47: __kasan_kmalloc+0x7f/0x90 fops_vcodec_open+0x85/0x1a0 Freed by task 47: __kasan_slab_free+0x43/0x70 kfree+0xee/0x3a0 fops_vcodec_release+0xb7/0x190Fix this by calling cancel_work_sync(&ctx->encode_work) before kfree(ctx).This ensures the workqueue handler is both cancelled (if pending) andsynchronized (waits for any running handler to complete) before thecontext is freed.Placement rationale: The fix is placed after v4l2_ctrl_handler_free()and before list_del_init(&ctx->list). At this point, all m2m operationsare done (v4l2_m2m_ctx_release() has returned), and we need to ensurethe workqueue is synchronized before removing ctx from the list andfreeing it.Note: The open error path does NOT need cancel_work_sync() becauseINIT_WORK() only initializes the work structure - it does not scheduleit. Work is only scheduled later during device_run() operations.

Description: In the Linux kernel, the following vulnerability has been resolved:ocfs2: fix use-after-free in ocfs2_fault() when VM_FAULT_RETRYfilemap_fault() may drop the mmap_lock before returning VM_FAULT_RETRY,as documented in mm/filemap.c: "If our return value has VM_FAULT_RETRY set, it's because the mmap_lock may be dropped before doing I/O or by lock_folio_maybe_drop_mmap()."When this happens, a concurrent munmap() can call remove_vma() and freethe vm_area_struct via RCU. The saved 'vma' pointer in ocfs2_fault() thenbecomes a dangling pointer, and the subsequent trace_ocfs2_fault() calldereferences it -- a use-after-free.Fix this by saving ip_blkno as a plain integer before callingfilemap_fault(), and removing vma from the trace event. Sinceip_blkno is copied by value before the lock can be dropped, itremains valid regardless of what happens to the vma or inodeafterward.

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-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.

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-2026-31649 Severity: Important CVSS3 score: 7.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: stmmac: fix integer underflow in chain modeThe jumbo_frm() chain-mode implementation unconditionally computes len = nopaged_len - bmax;where nopaged_len = skb_headlen(skb) (linear bytes only) and bmax isBUF_SIZE_8KiB or BUF_SIZE_2KiB. However, the caller stmmac_xmit()decides to invoke jumbo_frm() based on skb->len (total length includingpage fragments): is_jumbo = stmmac_is_jumbo_frm(priv, skb->len, enh_desc);When a packet has a small linear portion (nopaged_len <= bmax) but alarge total length due to page fragments (skb->len > bmax), thesubtraction wraps as an unsigned integer, producing a huge len value(~0xFFFFxxxx). This causes the while (len != 0) loop to executehundreds of thousands of iterations, passing skb->data + bmax * ipointers far beyond the skb buffer to dma_map_single(). On IOMMU-lessSoCs (the typical deployment for stmmac), this maps arbitrary kernelmemory to the DMA engine, constituting a kernel memory disclosure andpotential memory corruption from hardware.Fix this by introducing a buf_len local variable clamped tomin(nopaged_len, bmax). Computing len = nopaged_len - buf_len is thenalways safe: it is zero when the linear portion fits within a singledescriptor, causing the while (len != 0) loop to be skipped naturally,and the fragment loop in stmmac_xmit() handles page fragments afterward.

Description: Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption (JWE), JSON Web Signature (JWS), and JSON Web Token (JWT) standards. Prior to 4.1.4 and 3.0.5, decrypting a JSON Web Encryption (JWE) object will panic if the alg field indicates a key wrapping algorithm (one ending in KW, with the exception of A128GCMKW, A192GCMKW, and A256GCMKW) and the encrypted_key field is empty. The panic happens when cipher.KeyUnwrap() in key_wrap.go attempts to allocate a slice with a zero or negative length based on the length of the encrypted_key. This code path is reachable from ParseEncrypted() / ParseEncryptedJSON() / ParseEncryptedCompact() followed by Decrypt() on the resulting object. Note that the parse functions take a list of accepted key algorithms. If the accepted key algorithms do not include any key wrapping algorithms, parsing will fail and the application will be unaffected. This panic is also reachable by calling cipher.KeyUnwrap() directly with any ciphertext parameter less than 16 bytes long, but calling this function directly is less common. Panics can lead to denial of service. This vulnerability is fixed in 4.1.4 and 3.0.5.

CVE-2026-31685 Severity: Important CVSS3 score: 7.4

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: ip6t_eui64: reject invalid MAC header for all packets`eui64_mt6()` derives a modified EUI-64 from the Ethernet source addressand compares it with the low 64 bits of the IPv6 source address.The existing guard only rejects an invalid MAC header when`par->fragoff != 0`. For packets with `par->fragoff == 0`, `eui64_mt6()`can still reach `eth_hdr(skb)` even when the MAC header is not valid.Fix this by removing the `par->fragoff != 0` condition so that packetswith an invalid MAC header are rejected before accessing `eth_hdr(skb)`.

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

This avoids already some racy accesses.- In addition, now we try to check the state of the capture PCM stream that may be stopped in this function, which was the major pain point leading to UAF.

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: fix OOB reads parsing symlink error responseWhen a CREATE returns STATUS_STOPPED_ON_SYMLINK, smb2_check_message()returns success without any length validation, leaving the symlinkparsers as the only defense against an untrusted server.symlink_data() walks SMB 3.1.1 error contexts with the loop test "p ErrorId at offset 4 and p->ErrorDataLength at offset0. When the server-controlled ErrorDataLength advances p to within 1-7bytes of end, the next iteration will read past it. When the matchingcontext is found, sym->SymLinkErrorTag is read at offset 4 fromp->ErrorContextData with no check that the symlink header itself fits.smb2_parse_symlink_response() then bounds-checks the substitute nameusing SMB2_SYMLINK_STRUCT_SIZE as the offset of PathBuffer fromiov_base. That value is computed as sizeof(smb2_err_rsp) +sizeof(smb2_symlink_err_rsp), which is correct only whenErrorContextCount == 0.With at least one error context the symlink data sits 8 bytes deeper,and each skipped non-matching context shifts it further by 8 +ALIGN(ErrorDataLength, 8). The check is too short, allowing thesubstitute name read to run past iov_len. The out-of-bound heap bytesare UTF-16-decoded into the symlink target and returned to userspace viareadlink(2).Fix this all up by making the loops test require the full context headerto fit, rejecting sym if its header runs past end, and bound thesubstitute name against the actual position of sym->PathBuffer ratherthan a fixed offset.Because sub_offs and sub_len are 16bits, the pointer math will notoverflow here with the new greater-than.

The strncmp()later reads ea->ea_data[0..nlen-1] and the value bytes follow atea_data[nlen+1..nlen+vlen], so the actual end is ea->ea_data + nlen + 1+ vlen. Isn't pointer math fun?The earlier check (u8 *)ea > end - sizeof(*ea) only guarantees the8-byte header is in bounds, but since the last EA is placed within 8bytes of the end of the response, the name and value bytes are read pastthe end of iov.Fix this mess all up by using ea->ea_data as the base for the boundscheck.An "untrusted" server can use this to leak up to 8 bytes of kernel heapinto the EA name comparison and influence which WSL xattr the data isinterpreted as.

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: Fix recvmsg() unconditional requeueIf rxrpc_recvmsg() fails because MSG_DONTWAIT was specified but the call atthe front of the recvmsg queue already has its mutex locked, it requeuesthe call - whether or not the call is already queued. The call may be onthe queue because MSG_PEEK was also passed and so the call was not dequeuedor because the I/O thread requeued it.The unconditional requeue may then corrupt the recvmsg queue, leading tothings like UAFs or refcount underruns.Fix this by only requeuing the call if it isn't already on the queue - andmoving it to the front if it is already queued. If we don't queue it, wehave to put the ref we obtained by dequeuing it.Also, MSG_PEEK doesn't dequeue the call so shouldn't callrxrpc_notify_socket() for the call if we didn't use up all the data on thequeue, so fix that also.

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

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nf_tables: release flowtable after rcu grace period on errorCall synchronize_rcu() after unregistering the hooks from error path,since a hook that already refers to this flowtable can be alreadyregistered, exposing this flowtable to packet path and nfnetlink_hookcontrol plane.This error path is rare, it should only happen by reaching the maximumnumber hooks or by failing to set up to hardware offload, just callsynchronize_rcu().There is a check for already used device hooks by different flowtablethat could result in EEXIST at this late stage. The hook parser can beupdated to perform this check earlier to this error path really becomesrarely exercised.Uncovered by KASAN reported as use-after-free from nfnetlink_hook pathwhen dumping hooks.

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

CVE-2026-23450 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:net/smc: fix NULL dereference and UAF in smc_tcp_syn_recv_sock()Syzkaller reported a panic in smc_tcp_syn_recv_sock() [1].smc_tcp_syn_recv_sock() is called in the TCP receive path(softirq) via icsk_af_ops->syn_recv_sock on the clcsock (TCPlistening socket). It reads sk_user_data to get the smc_sockpointer. However, when the SMC listen socket is being closedconcurrently, smc_close_active() sets clcsock->sk_user_datato NULL under sk_callback_lock, and then the smc_sock itselfcan be freed via sock_put() in smc_release().This leads to two issues:1) NULL pointer dereference: sk_user_data is NULL when accessed.2) Use-after-free: sk_user_data is read as non-NULL, but the smc_sock is freed before its fields (e.g., queued_smc_hs, ori_af_ops) are accessed.The race window looks like this (the syzkaller crash [1]triggers via the SYN cookie path: tcp_get_cookie_sock() ->smc_tcp_syn_recv_sock(), but the normal tcp_check_req() pathhas the same race): CPU A (softirq) CPU B (process ctx) tcp_v4_rcv() TCP_NEW_SYN_RECV: sk = req->rsk_listener sock_hold(sk) /* No lock on listener */ smc_close_active(): write_lock_bh(cb_lock) sk_user_data = NULL write_unlock_bh(cb_lock) ... smc_clcsock_release() sock_put(smc->sk) x2 -> smc_sock freed! tcp_check_req() smc_tcp_syn_recv_sock(): smc = user_data(sk) -> NULL or dangling smc->queued_smc_hs -> crash!Note that the clcsock and smc_sock are two independent objectswith separate refcounts. TCP stack holds a reference on theclcsock, which keeps it alive, but this does NOT prevent thesmc_sock from being freed.Fix this by using RCU and refcount_inc_not_zero() to safelyaccess smc_sock. Since smc_tcp_syn_recv_sock() is called inthe TCP three-way handshake path, taking read_lock_bh onsk_callback_lock is too heavy and would not survive a SYNflood attack. Using rcu_read_lock() is much more lightweight.- Set SOCK_RCU_FREE on the SMC listen socket so that smc_sock freeing is deferred until after the RCU grace period. This guarantees the memory is still valid when accessed inside rcu_read_lock().- Use rcu_read_lock() to protect reading sk_user_data.- Use refcount_inc_not_zero(&smc->sk.sk_refcnt) to pin the smc_sock. If the refcount has already reached zero (close path completed), it returns false and we bail out safely.Note: smc_hs_congested() has a similar lockless read ofsk_user_data without rcu_read_lock(), but it only checks forNULL and accesses the global smc_hs_wq, never dereferencingany smc_sock field, so it is not affected.Reproducer was verified with mdelay injection and smc_run,the issue no longer occurs with this patch applied.[1] https://syzkaller.appspot.com/bug?extid=827ae2bfb3a3529333e9

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.

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.

In TDXenvironments with remote attestation, quotes are not considered private,and can be forwarded to an attestation server.Catch scenarios where the host specifies a response length larger thanthe guest's allocation, or otherwise races modifying the response whilethe guest consumes it.This prevents contents beyond the pages allocated for `quote_buf`(up to TSM_REPORT_OUTBLOB_MAX) from being read out to guest userspace,and possibly forwarded in attestation requests.Recall that some deployments want per-container configs-tsm-reportinterfaces, so the leak may cross container protection boundaries, notjust local root.

When both paths manipulatehdev->req_status/req_rsp concurrently, the close path may free theresponse skb first, and the still-running hw_error path hits aslab-use-after-free in kfree_skb().Wrap the whole recovery sequence in hci_req_sync_lock/unlock so itis serialized with every other synchronous HCI command issuer.Below is the data race report and the kasan report: BUG: data-race in __hci_cmd_sync_sk / btintel_shutdown_combined read of hdev->req_rsp at net/bluetooth/hci_sync.c:199 by task kworker/u17:1/83: __hci_cmd_sync_sk+0x12f2/0x1c30 net/bluetooth/hci_sync.c:200 __hci_cmd_sync+0x55/0x80 net/bluetooth/hci_sync.c:223 btintel_hw_error+0x114/0x670 drivers/bluetooth/btintel.c:254 hci_error_reset+0x348/0xa30 net/bluetooth/hci_core.c:1030 write/free by task ioctl/22580: btintel_shutdown_combined+0xd0/0x360 drivers/bluetooth/btintel.c:3648 hci_dev_close_sync+0x9ae/0x2c10 net/bluetooth/hci_sync.c:5246 hci_dev_do_close+0x232/0x460 net/bluetooth/hci_core.c:526 BUG: KASAN: slab-use-after-free in sk_skb_reason_drop+0x43/0x380 net/core/skbuff.c:1202 Read of size 4 at addr ffff888144a738dc by task kworker/u17:1/83: __hci_cmd_sync_sk+0x12f2/0x1c30 net/bluetooth/hci_sync.c:200 __hci_cmd_sync+0x55/0x80 net/bluetooth/hci_sync.c:223 btintel_hw_error+0x186/0x670 drivers/bluetooth/btintel.c:260

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix fanout UAF in packet_release() via NETDEV_UP race`packet_release()` has a race window where `NETDEV_UP` can re-register asocket into a fanout group's `arr[]` array. The re-registration is notcleaned up by `fanout_release()`, leaving a dangling pointer in the fanoutarray.`packet_release()` does NOT zero `po->num` in its `bind_lock` section.After releasing `bind_lock`, `po->num` is still non-zero and `po->ifindex`still matches the bound device. A concurrent `packet_notifier(NETDEV_UP)`that already found the socket in `sklist` can re-register the hook.For fanout sockets, this re-registration calls `__fanout_link(sk, po)`which adds the socket back into `f->arr[]` and increments `f->num_members`,but does NOT increment `f->sk_ref`.The fix sets `po->num` to zero in `packet_release` while `bind_lock` isheld to prevent NETDEV_UP from linking, preventing the race window.This bug was found following an additional audit with Claude Code basedon CVE-2025-38617.

CVE-2026-31525 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix undefined behavior in interpreter sdiv/smod for INT_MINThe BPF interpreter's signed 32-bit division and modulo handlers usethe kernel abs() macro on s32 operands. The abs() macro documentation(include/linux/math.h) explicitly states the result is undefined whenthe input is the type minimum. When DST contains S32_MIN (0x80000000),abs((s32)DST) triggers undefined behavior and returns S32_MIN unchangedon arm64/x86. This value is then sign-extended to u64 as0xFFFFFFFF80000000, causing do_div() to compute the wrong result.The verifier's abstract interpretation (scalar32_min_max_sdiv) computesthe mathematically correct result for range tracking, creating averifier/interpreter mismatch that can be exploited for out-of-boundsmap value access.Introduce abs_s32() which handles S32_MIN correctly by casting to u32before negating, avoiding signed overflow entirely. Replace all 8abs((s32)...) call sites in the interpreter's sdiv32/smod32 handlers.s32 is the only affected case -- the s64 division/modulo handlers donot use abs().

Description: In the Linux kernel, the following vulnerability has been resolved:perf: Make sure to use pmu_ctx->pmu for groupsOliver reported that x86_pmu_del() ended up doing an out-of-bound memory accesswhen group_sched_in() fails and needs to roll back.This *should* be handled by the transaction callbacks, but he found that whenthe group leader is a software event, the transaction handlers of the wrong PMUare used. Despite the move_group case in perf_event_open() and group_sched_in()using pmu_ctx->pmu.Turns out, inherit uses event->pmu to clone the events, effectively undoing themove_group case for all inherited contexts. Fix this by also making inherit usepmu_ctx->pmu, ensuring all inherited counters end up in the same pmu context.Similarly, __perf_event_read() should use equally use pmu_ctx->pmu for thegroup case.

CVE-2026-31533 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:net/tls: fix use-after-free in -EBUSY error path of tls_do_encryptionThe -EBUSY handling in tls_do_encryption(), introduced by commit859054147318 ("net: tls: handle backlogging of crypto requests"), hasa use-after-free due to double cleanup of encrypt_pending and thescatterlist entry.When crypto_aead_encrypt() returns -EBUSY, the request is enqueued tothe cryptd backlog and the async callback tls_encrypt_done() will beinvoked upon completion. That callback unconditionally restores thescatterlist entry (sge->offset, sge->length) and decrementsctx->encrypt_pending. However, if tls_encrypt_async_wait() returns anerror, the synchronous error path in tls_do_encryption() performs thesame cleanup again, double-decrementing encrypt_pending anddouble-restoring the scatterlist.The double-decrement corrupts the encrypt_pending sentinel (initializedto 1), making tls_encrypt_async_wait() permanently skip the wait forpending async callbacks. A subsequent sendmsg can then free thetls_rec via bpf_exec_tx_verdict() while a cryptd callback is stillpending, resulting in a use-after-free when the callback fires on thefreed record.Fix this by skipping the synchronous cleanup when the -EBUSY asyncwait returns an error, since the callback has already handledencrypt_pending and sge restoration.

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: x86: Use scratch field in MMIO fragment to hold small write valuesWhen exiting to userspace to service an emulated MMIO write, copy theto-be-written value to a scratch field in the MMIO fragment if the sizeof the data payload is 8 bytes or less, i.e. can fit in a single chunk,instead of pointing the fragment directly at the source value.This fixes a class of use-after-free bugs that occur when the emulatorinitiates a write using an on-stack, local variable as the source, thewrite splits a page boundary, *and* both pages are MMIO pages. BecauseKVM's ABI only allows for physically contiguous MMIO requests, accessesthat split MMIO pages are separated into two fragments, and are sent touserspace one at a time. When KVM attempts to complete userspace MMIO inresponse to KVM_RUN after the first fragment, KVM will detect the secondfragment and generate a second userspace exit, and reference the on-stackvariable.The issue is most visible if the second KVM_RUN is performed by a separatetask, in which case the stack of the initiating task can show up as trulyfreed data. ================================================================== BUG: KASAN: use-after-free in complete_emulated_mmio+0x305/0x420 Read of size 1 at addr ffff888009c378d1 by task syz-executor417/984 CPU: 1 PID: 984 Comm: syz-executor417 Not tainted 5.10.0-182.0.0.95.h2627.eulerosv2r13.x86_64 #3 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.15.0-0-g2dd4b9b3f840-prebuilt.qemu.org 04/01/2014 Call Trace: dump_stack+0xbe/0xfd print_address_description.constprop.0+0x19/0x170 __kasan_report.cold+0x6c/0x84 kasan_report+0x3a/0x50 check_memory_region+0xfd/0x1f0 memcpy+0x20/0x60 complete_emulated_mmio+0x305/0x420 kvm_arch_vcpu_ioctl_run+0x63f/0x6d0 kvm_vcpu_ioctl+0x413/0xb20 __se_sys_ioctl+0x111/0x160 do_syscall_64+0x30/0x40 entry_SYSCALL_64_after_hwframe+0x67/0xd1 RIP: 0033:0x42477d Code: <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b0 ff ff ff f7 d8 64 89 01 48 RSP: 002b:00007faa8e6890e8 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 RAX: ffffffffffffffda RBX: 00000000004d7338 RCX: 000000000042477d RDX: 0000000000000000 RSI: 000000000000ae80 RDI: 0000000000000005 RBP: 00000000004d7330 R08: 00007fff28d546df R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000246 R12: 00000000004d733c R13: 0000000000000000 R14: 000000000040a200 R15: 00007fff28d54720 The buggy address belongs to the page: page:0000000029f6a428 refcount:0 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x9c37 flags: 0xfffffc0000000(node=0|zone=1|lastcpupid=0x1fffff) raw: 000fffffc0000000 0000000000000000 ffffea0000270dc8 0000000000000000 raw: 0000000000000000 0000000000000000 00000000ffffffff 0000000000000000 page dumped because: kasan: bad access detected Memory state around the buggy address: ffff888009c37780: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ffff888009c37800: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff >ffff888009c37880: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ^ ffff888009c37900: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ffff888009c37980: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ==================================================================The bug can also be reproduced with a targeted KVM-Unit-Test by hackingKVM to fill a large on-stack variable in complete_emulated_mmio(), i.e. byoverwrite the data value with garbage.Limit the use of the scratch fields to 8-byte or smaller accesses, and tojust writes, as larger accesses and reads are not affected thanks toimplementation details in the emulator, but add a sanity check to ensurethose details don't change in the future.

Both tcp_prot andtcpv6_prot have their slab caches created with this flagvia proto_register().However, MPTCP's mptcp_subflow_init() copies tcpv6_prot intotcpv6_prot_override during inet_init() (fs_initcall, level 5),before inet6_init() (module_init/device_initcall, level 6) hascalled proto_register(&tcpv6_prot). At that point,tcpv6_prot.slab is still NULL, so tcpv6_prot_override.slabremains NULL permanently.This causes MPTCP v6 subflow child sockets to be allocated viakmalloc (falling into kmalloc-4k) instead of the TCPv6 slabcache. The kmalloc-4k cache lacks SLAB_TYPESAFE_BY_RCU, sowhen these sockets are freed without SOCK_RCU_FREE (which iscleared for child sockets by design), the memory can beimmediately reused. Concurrent ehash lookups underrcu_read_lock can then access freed memory, triggering aslab-use-after-free in __inet_lookup_established.Fix this by splitting the IPv6-specific initialization out ofmptcp_subflow_init() into a new mptcp_subflow_v6_init(), calledfrom mptcp_proto_v6_init() before protocol registration. Thisensures tcpv6_prot_override.slab correctly inherits theSLAB_TYPESAFE_BY_RCU slab cache.

CVE-2026-4878 Severity: Important CVSS3 score: 7.0

Description: A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation.

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.

CVE-2026-32316 Severity: Moderate CVSS3 score: 6.8

Description: jq is a command-line JSON processor. An integer overflow vulnerability exists through version 1.8.1 within the jvp_string_append() and jvp_string_copy_replace_bad functions, where concatenating strings with a combined length exceeding 2^31 bytes causes a 32-bit unsigned integer overflow in the buffer allocation size calculation, resulting in a drastically undersized heap buffer. Subsequent memory copy operations then write the full string data into this undersized buffer, causing a heap buffer overflow classified as CWE-190 (Integer Overflow) leading to CWE-122 (Heap-based Buffer Overflow). Any system evaluating untrusted jq queries is affected, as an attacker can crash the process or potentially achieve further exploitation through heap corruption by crafting queries that produce extremely large strings. The root cause is the absence of string size bounds checking, unlike arrays and objects which already have size limits. The issue has been addressed in commit e47e56d226519635768e6aab2f38f0ab037c09e5.

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:nvme-tcp: remove tag set when second admin queue config failsCommit 104d0e2f6222 ("nvme-fabrics: reset admin connection for secureconcatenation") modified nvme_tcp_setup_ctrl() to callnvme_tcp_configure_admin_queue() twice. The first call prepares forDH-CHAP negotitation, and the second call is required for secureconcatenation. However, this change triggered BUG KASAN slab-use-after-free in blk_mq_queue_tag_busy_iter(). This BUG can be recreated byrepeating the blktests test case nvme/063 a few times [1].When the BUG happens, nvme_tcp_create_ctrl() fails in the call chainbelow:nvme_tcp_create_ctrl() nvme_tcp_alloc_ctrl() new=true ...

Free up the nvme_tcp_ctrl and admin_tag_setThe first call of nvme_tcp_configure_admin_queue() succeeds withnew=true argument. The second call fails with new=false argument. Thissecond call does not call nvme_remove_admin_tag_set() on failure, due tothe new=false argument. Then the admin tag set is not removed. However,nvme_tcp_create_ctrl() assumes that nvme_tcp_setup_ctrl() would callnvme_remove_admin_tag_set(). Then it frees up struct nvme_tcp_ctrl whichhas admin_tag_set field. Later on, the timeout handler accesses theadmin_tag_set field and causes the BUG KASAN slab-use-after-free.To not leave the admin tag set, call nvme_remove_admin_tag_set() whenthe second nvme_tcp_configure_admin_queue() call fails. Do not returnfrom nvme_tcp_setup_ctrl() on failure. Instead, jump to "destroy_admin"go-to label to call nvme_tcp_teardown_admin_queue() which callsnvme_remove_admin_tag_set().

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

Description: In the Linux kernel, the following vulnerability has been resolved:vsock/virtio: Coalesce only linear skbvsock/virtio common tries to coalesce buffers in rx queue: if a linear skb(with a spare tail room) is followed by a small skb (length limited byGOOD_COPY_LEN = 128), an attempt is made to join them.Since the introduction of MSG_ZEROCOPY support, assumption that a small skbwill always be linear is incorrect. In the zerocopy case, data is lost andthe linear skb is appended with uninitialized kernel memory.Of all 3 supported virtio-based transports, only loopback-transport isaffected. G2H virtio-transport rx queue operates on explicitly linear skbs;see virtio_vsock_alloc_linear_skb() in virtio_vsock_rx_fill(). H2Gvhost-transport may allocate non-linear skbs, but only for sizes that arenot considered for coalescence; see PAGE_ALLOC_COSTLY_ORDER invirtio_vsock_alloc_skb().Ensure only linear skbs are coalesced. Note that skb_tailroom(last_skb) > 0guarantees last_skb is linear.

The corresponding size valueprovided by this driver to alloc_candev() is KVASER_PCIEFD_CAN_TX_MAX_COUNTwhich is 17.But later echo_skb_max is rounded up to the nearest power of two (for themax case, that would be 32) and the tx/ack indices calculated furtherduring tx/rx may exceed the upper array boundary.

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]

CVE-2026-23276 Severity: Moderate CVSS3 score: 6.5

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.

When called frommesh_rx_csa_frame(), the parsed action-frame elements may not contain aMesh Configuration IE, leaving ie->mesh_config NULL and triggering akernel NULL pointer dereference.The other two callers are already safe: - ieee80211_mesh_rx_bcn_presp() checks !elems->mesh_config before calling mesh_matches_local() - mesh_plink_get_event() is only reached through mesh_process_plink_frame(), which checks !elems->mesh_config, toomesh_rx_csa_frame() is the only caller that passes raw parsed elementsto mesh_matches_local() without guarding mesh_config.

CVE-2026-24401 Severity: Moderate CVSS3 score: 6.5

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.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:net: sched: act_csum: validate nested VLAN headerstcf_csum_act() walks nested VLAN headers directly from skb->data when anskb still carries in-payload VLAN tags. The current code readsvlan->h_vlan_encapsulated_proto and then pulls VLAN_HLEN bytes withoutfirst ensuring that the full VLAN header is present in the linear area.If only part of an inner VLAN header is linearized, accessingh_vlan_encapsulated_proto reads past the linear area, and the followingskb_pull(VLAN_HLEN) may violate skb invariants.Fix this by requiring pskb_may_pull(skb, VLAN_HLEN) before accessing andpulling each nested VLAN header. If the header still is not fullyavailable, drop the packet through the existing error path.

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

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

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

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

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

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

The actual cleanup of 'tr->progs_hlist' in'bpf_shim_tramp_link_release' is deferred. During this window, anotherprocess can cause a use-after-free via 'bpf_trampoline_link_cgroup_shim'.Based on Martin KaFai Lau's suggestions, I have created a simple patch.To fix this: Add an atomic non-zero check in 'bpf_trampoline_link_cgroup_shim'. Only increment the refcount if it is not already zero.Testing: I verified the fix by adding a delay in 'bpf_shim_tramp_link_release' to make the bug easier to trigger:static void bpf_shim_tramp_link_release(struct bpf_link *link){ /* ... */ if (!shim_link->trampoline) return;+ msleep(100); WARN_ON_ONCE(bpf_trampoline_unlink_prog(&shim_link->link, shim_link->trampoline, NULL)); bpf_trampoline_put(shim_link->trampoline);}Before the patch, running a PoC easily reproduced the crash(almost 100%)with a call trace similar to KaiyanM's report.After the patch, the bug no longer occurs even after millions ofiterations.

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-2026-23413 Severity: Moderate CVSS3 score: 6.4

Description: In the Linux kernel, the following vulnerability has been resolved:clsact: Fix use-after-free in init/destroy rollback asymmetryFix a use-after-free in the clsact qdisc upon init/destroy rollback asymmetry.The latter is achieved by first fully initializing a clsact instance, andthen in a second step having a replacement failure for the new clsact qdiscinstance. clsact_init() initializes ingress first and then takes care of theegress part. This can fail midway, for example, via tcf_block_get_ext(). Uponfailure, the kernel will trigger the clsact_destroy() callback.Commit 1cb6f0bae504 ("bpf: Fix too early release of tcx_entry") details theway how the transition is happening. If tcf_block_get_ext on the q->ingress_blockends up failing, we took the tcx_miniq_inc reference count on the ingressside, but not yet on the egress side. clsact_destroy() tests whether the{ingress,egress}_entry was non-NULL. However, even in midway failure on thereplacement, both are in fact non-NULL with a valid egress_entry from theprevious clsact instance.What we really need to test for is whether the qdisc instance-specific ingressor egress side previously got initialized. This adds a small helper for checkingthe miniq initialization called mini_qdisc_pair_inited, and utilizes that uponclsact_destroy() in order to fix the use-after-free scenario. Convert theingress_destroy() side as well so both are consistent to each other.

When the team device later calls dev_hard_header() ordev_parse_header(), these callbacks can run with the team net_deviceinstead of the real lower device, so netdev_priv(dev) is interpreted asthe wrong private type and can crash.The syzbot report shows a crash in bond_header_create(), but the rootcause is in team: the topology is gre -> bond -> team, and team callsthe inherited header_ops with its own net_device instead of the lowerdevice, so bond_header_create() receives a team device and interpretsnetdev_priv() as bonding private data, causing a type confusion crash.Fix this by introducing team header_ops wrappers for create/parse,selecting a team port under RCU, and calling the lower device callbackswith port->dev, so each callback always sees the correct net_devicecontext.Also pass the selected lower device to the lower parse callback, sorecursion is bounded in stacked non-Ethernet topologies and parsecallbacks always run with the correct device context.

If the net namespace is torn downbefore that work runs, the associated struct net may already havebeen freed, and xfrm_hash_rebuild() may then dereference stale memory.xfrm_policy_fini() already flushes policy_hash_work during teardown,but it does not synchronize policy_hthresh.work.Synchronize policy_hthresh.work in xfrm_policy_fini() as well, so thequeued work cannot outlive the net namespace teardown and access afreed struct net.

Description: In the Linux kernel, the following vulnerability has been resolved:driver core: platform: use generic driver_override infrastructureWhen a driver is probed through __driver_attach(), the bus' match()callback is called without the device lock held, thus accessing thedriver_override field without a lock, which can cause a UAF.Fix this by using the driver-core driver_override infrastructure takingcare of proper locking internally.Note that calling match() from __driver_attach() without the device lockheld is intentional.

CVE-2026-31530 Severity: Moderate CVSS3 score: 6.4

Description: In the Linux kernel, the following vulnerability has been resolved:cxl/port: Fix use after free of parent_port in cxl_detach_ep()cxl_detach_ep() is called during bottom-up removal when all CXL memorydevices beneath a switch port have been removed. For each port in thehierarchy it locks both the port and its parent, removes the endpoint,and if the port is now empty, marks it dead and unregisters the portby calling delete_switch_port(). There are two places during this workwhere the parent_port may be used after freeing:First, a concurrent detach may have already processed a port by thetime a second worker finds it via bus_find_device(). Without pinningparent_port, it may already be freed when we discover port->dead andattempt to unlock the parent_port. In a production kernel that's asilent memory corruption, with lock debug, it looks like this:[]DEBUG_LOCKS_WARN_ON(__owner_task(owner) != get_current())[]WARNING: kernel/locking/mutex.c:949 at __mutex_unlock_slowpath+0x1ee/0x310[]Call Trace:[]mutex_unlock+0xd/0x20[]cxl_detach_ep+0x180/0x400 [cxl_core][]devm_action_release+0x10/0x20[]devres_release_all+0xa8/0xe0[]device_unbind_cleanup+0xd/0xa0[]really_probe+0x1a6/0x3e0Second, delete_switch_port() releases three devm actions registeredagainst parent_port. The last of those is unregister_port() and itcalls device_unregister() on the child port, which can cascade. Ifparent_port is now also empty the device core may unregister and freeit too. So by the time delete_switch_port() returns, parent_port maybe free, and the subsequent device_unlock(&parent_port->dev) operateson freed memory. The kernel log looks same as above, with a differentoffset in cxl_detach_ep().Both of these issues stem from the absence of a lifetime guaranteebetween a child port and its parent port.Establish a lifetime rule for ports: child ports hold a reference totheir parent device until release. Take the reference when the portis allocated and drop it when released. This ensures the parent isvalid for the full lifetime of the child and eliminates the use afterfree window in cxl_detach_ep().This is easily reproduced with a reload of cxl_acpi in QEMU with CXLdevices present.

CVE-2026-31688 Severity: Moderate CVSS3 score: 6.4

Description: In the Linux kernel, the following vulnerability has been resolved:driver core: enforce device_lock for driver_match_device()Currently, driver_match_device() is called from three sites. One site(__device_attach_driver) holds device_lock(dev), but the other two(bind_store and __driver_attach) do not. This inconsistency means thatbus match() callbacks are not guaranteed to be called with the lockheld.Fix this by introducing driver_match_device_locked(), which guaranteesholding the device lock using a scoped guard. Replace the unlocked callsin bind_store() and __driver_attach() with this new helper. Also add alock assertion to driver_match_device() to enforce this guarantee.This consistency also fixes a known race condition. The driver_overrideimplementation relies on the device_lock, so the missing lock led to theuse-after-free (UAF) reported in Bugzilla for buses using this field.Stress testing the two newly locked paths for 24 hours withCONFIG_PROVE_LOCKING and CONFIG_LOCKDEP enabled showed no UAF recurrenceand no lockdep warnings.

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---

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

Description: In the Linux kernel, the following vulnerability has been resolved:Squashfs: check metadata block offset is within rangeSyzkaller reports a "general protection fault in squashfs_copy_data"This is ultimately caused by a corrupted index look-up table, whichproduces a negative metadata block offset.This is subsequently passed to squashfs_copy_data (viasquashfs_read_metadata) where the negative offset causes an out of boundsaccess.The fix is to check that the offset is within range insquashfs_read_metadata. This will trap this and other cases.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:via_wdt: fix critical boot hang due to unnamed resource allocationThe VIA watchdog driver uses allocate_resource() to reserve a MMIOregion for the watchdog control register. However, the allocatedresource was not given a name, which causes the kernel resource treeto contain an entry marked as "" under /proc/iomem on x86platforms.During boot, this unnamed resource can lead to a critical hang becausesubsequent resource lookups and conflict checks fail to handle theinvalid entry properly.

Per Intel's SDM,XSAVE saves XSTATE_BV as '0' for components that are disabled via XFD(and non-compacted XSAVE saves the initial configuration of the statecomponent): If XSAVE, XSAVEC, XSAVEOPT, or XSAVES is saving the state component i, the instruction does not generate #NM when XCR0[i] = IA32_XFD[i] = 1; instead, it operates as if XINUSE[i] = 0 (and the state component was in its initial state): it saves bit i of XSTATE_BV field of the XSAVE header as 0; in addition, XSAVE saves the initial configuration of the state component (the other instructions do not save state component i).Alternatively, KVM could always do XRSTOR with XFD=0, e.g. by usinga constant XFD based on the set of enabled features when XSAVEing fora struct fpu_guest. However, having XSTATE_BV[i]=1 for XFD-disabledfeatures can only happen in the above interrupt case, or in similarscenarios involving preemption on preemptible kernels, becausefpu_swap_kvm_fpstate()'s call to save_fpregs_to_fpstate() saves theoutgoing FPU state with the current XFD; and that is (on all but thefirst WRMSR to XFD) the guest XFD.Therefore, XFD can only go out of sync with XSTATE_BV in the aboveinterrupt case, or in similar scenarios involving preemption onpreemptible kernels, and it we can consider it (de facto) part of KVMABI that KVM_GET_XSAVE returns XSTATE_BV[i]=0 for XFD-disabled features.[Move clea---truncated---

CVE-2026-31503 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:udp: Fix wildcard bind conflict check when using hash2When binding a udp_sock to a local address and port, UDP usestwo hashes (udptable->hash and udptable->hash2) for collisiondetection. The current code switches to "hash2" whenhslot->count > 10."hash2" is keyed by local address and local port."hash" is keyed by local port only.The issue can be shown in the following bind sequence (pseudo code):bind(fd1, "[fd00::1]:8888")bind(fd2, "[fd00::2]:8888")bind(fd3, "[fd00::3]:8888")bind(fd4, "[fd00::4]:8888")bind(fd5, "[fd00::5]:8888")bind(fd6, "[fd00::6]:8888")bind(fd7, "[fd00::7]:8888")bind(fd8, "[fd00::8]:8888")bind(fd9, "[fd00::9]:8888")bind(fd10, "[fd00::10]:8888")/* Correctly return -EADDRINUSE because "hash" is used * instead of "hash2". udp_lib_lport_inuse() detects the * conflict. */bind(fail_fd, "[::]:8888")/* After one more socket is bound to "[fd00::11]:8888", * hslot->count exceeds 10 and "hash2" is used instead. */bind(fd11, "[fd00::11]:8888")bind(fail_fd, "[::]:8888") /* succeeds unexpectedly */The same issue applies to the IPv4 wildcard address "0.0.0.0"and the IPv4-mapped wildcard address "::ffff:0.0.0.0". Forexample, if there are existing sockets bound to"192.168.1.[1-11]:8888", then binding "0.0.0.0:8888" or"[::ffff:0.0.0.0]:8888" can also miss the conflict whenhslot->count > 10.TCP inet_csk_get_port() already has the correct check ininet_use_bhash2_on_bind(). Rename it toinet_use_hash2_on_bind() and move it to inet_hashtables.hso udp.c can reuse it in this fix.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: f_phonet: fix skb frags[] overflow in pn_rx_complete()A broken/bored/mean USB host can overflow the skb_shared_info->frags[]array on a Linux gadget exposing a Phonet function by sending anunbounded sequence of full-page OUT transfers.pn_rx_complete() finalizes the skb only when req->actual < req->length,where req->length is set to PAGE_SIZE by the gadget. If the host alwayssends exactly PAGE_SIZE bytes per transfer, fp->rx.skb will never bereset and each completion will add another fragment viaskb_add_rx_frag(). Once nr_frags exceeds MAX_SKB_FRAGS (default 17),subsequent frag stores overwrite memory adjacent to the shinfo on theheap.Drop the skb and account a length error when the frag limit is reached,matching the fix applied in t7xx by commit f0813bcd2d9d ("net: wwan:t7xx: fix potential skb->frags overflow in RX path").

CVE-2026-39979 Severity: Moderate CVSS3 score: 6.1

Description: jq is a command-line JSON processor. In commits before 2f09060afab23fe9390cce7cb860b10416e1bf5f, the jv_parse_sized() API in libjq accepts a counted buffer with an explicit length parameter, but its error-handling path formats the input buffer using %s in jv_string_fmt(), which reads until a NUL terminator is found rather than respecting the caller-supplied length. This means that when malformed JSON is passed in a non-NUL-terminated buffer, the error construction logic performs an out-of-bounds read past the end of the buffer. The vulnerability is reachable by any libjq consumer calling jv_parse_sized() with untrusted input, and depending on memory layout, can result in memory disclosure or process termination. The issue has been patched in commit 2f09060afab23fe9390cce7cb860b10416e1bf5f.

Description: A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables. The issue occurs when processing specially crafted XCOFF object files, where a relocation type value is not properly validated before being used. This can cause the program to read memory outside of intended bounds. As a result, affected tools may crash or expose unintended memory contents, leading to denial-of-service or limited information disclosure risks.

CVE-2025-68741 Severity: Moderate CVSS3 score: 6.0

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: qla2xxx: Fix improper freeing of purex itemIn qla2xxx_process_purls_iocb(), an item is allocated viaqla27xx_copy_multiple_pkt(), which internally callsqla24xx_alloc_purex_item().The qla24xx_alloc_purex_item() function may return a pre-allocated itemfrom a per-adapter pool for small allocations, instead of dynamicallyallocating memory with kzalloc().An error handling path in qla2xxx_process_purls_iocb() incorrectly useskfree() to release the item. If the item was from the pre-allocatedpool, calling kfree() on it is a bug that can lead to memory corruption.Fix this by using the correct deallocation function,qla24xx_free_purex_item(), which properly handles both dynamicallyallocated and pre-allocated items.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: pm8001: Fix use-after-free in pm8001_queue_command()Commit e29c47fe8946 ("scsi: pm8001: Simplify pm8001_task_exec()") refactorspm8001_queue_command(), however it introduces a potential cause of a doublefree scenario when it changes the function to return -ENODEV in case of phydown/device gone state.In this path, pm8001_queue_command() updates task status and callstask_done to indicate to upper layer that the task has been handled.However, this also frees the underlying SAS task. A -ENODEV is thenreturned to the caller. When libsas sas_ata_qc_issue() receives this errorvalue, it assumes the task wasn't handled/queued by LLDD and proceeds toclean up and free the task again, resulting in a double free.Since pm8001_queue_command() handles the SAS task in this case, it shouldreturn 0 to the caller indicating that the task has been handled.

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

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

CVE-2025-68770 Severity: Moderate CVSS3 score: 5.9

Description: In the Linux kernel, the following vulnerability has been resolved:bnxt_en: Fix XDP_TX pathFor XDP_TX action in bnxt_rx_xdp(), clearing of the event flags is notcorrect. __bnxt_poll_work() -> bnxt_rx_pkt() -> bnxt_rx_xdp() may belooping within NAPI and some event flags may be set in earlieriterations. In particular, if BNXT_TX_EVENT is set earlier indicatingsome XDP_TX packets are ready and pending, it will be cleared if it isXDP_TX action again. Normally, we will set BNXT_TX_EVENT again when wesuccessfully call __bnxt_xmit_xdp(). But if the TX ring has no moreroom, the flag will not be set. This will cause the TX producer to beahead but the driver will not hit the TX doorbell.For multi-buf XDP_TX, there is no need to clear the event flags and setBNXT_AGG_EVENT. The BNXT_AGG_EVENT flag should have been set earlier inbnxt_rx_pkt().The visible symptom of this is that the RX ring associated with theTX XDP ring will eventually become empty and all packets will be dropped.Because this condition will cause the driver to not refill the RX ringseeing that the TX ring has forever pending XDP_TX packets.The fix is to only clear BNXT_RX_EVENT when we have successfullycalled __bnxt_xmit_xdp().

Description: In the Linux kernel, the following vulnerability has been resolved:net/handshake: duplicate handshake cancellations leak socketWhen a handshake request is cancelled it is removed from thehandshake_net->hn_requests list, but it is still present in thehandshake_rhashtbl until it is destroyed.If a second cancellation request arrives for the same handshake request,then remove_pending() will return false... and assumingHANDSHAKE_F_REQ_COMPLETED isn't set in req->hr_flags, we'll continueprocessing through the out_true label, where we put another reference onthe sock and a refcount underflow occurs.This can happen for example if a handshake times out - particularly ifthe SUNRPC client sends the AUTH_TLS probe to the server but doesn'tfollow it up with the ClientHello due to a problem with tlshd. When thetimeout is hit on the server, the server will send a FIN, which triggersa cancellation request via xs_reset_transport(). When the timeout ishit on the client, another cancellation request happens viaxs_tls_handshake_sync().Add a test_and_set_bit(HANDSHAKE_F_REQ_COMPLETED) in the pending cancelpath so duplicate cancels can be detected.

Thisfunction does: get_cpu_ptr(dev->tstats)Since teql_master_setup() does not set dev->pcpu_stat_type toNETDEV_PCPU_STAT_TSTATS, the core network stack never allocates tstatsfor teql0, so dev->tstats is NULL. get_cpu_ptr(NULL) computesNULL + __per_cpu_offset[cpu], resulting in a page fault.

CVE-2026-28390 Severity: Moderate CVSS3 score: 5.9

Description: Issue summary: During processing of a crafted CMS EnvelopedData messagewith KeyTransportRecipientInfo a NULL pointer dereference can happen.Impact summary: Applications that process attacker-controlled CMS data maycrash before authentication or cryptographic operations occur resulting inDenial of Service.When a CMS EnvelopedData message that uses KeyTransportRecipientInfo withRSA-OAEP encryption is processed, the optional parameters field ofRSA-OAEP SourceFunc algorithm identifier is examined without checkingfor its presence. This results in a NULL pointer dereference if the fieldis missing.Applications and services that call CMS_decrypt() on untrusted input(e.g., S/MIME processing or CMS-based protocols) are vulnerable.The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by thisissue, as the affected code is outside the OpenSSL FIPS module boundary.

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: Only put the call ref if one was acquiredrxrpc_input_packet_on_conn() can process a to-client packet after thecurrent client call on the channel has already been torn down. In thatcase chan->call is NULL, rxrpc_try_get_call() returns NULL and there isno reference to drop.The client-side implicit-end error path does not account for that andunconditionally calls rxrpc_put_call(). This turns a protocol errorpath into a kernel crash instead of rejecting the packet.Only drop the call reference if one was actually acquired. Keep theexisting protocol error handling unchanged.

CVE-2026-3904 Severity: Moderate CVSS3 score: 5.9

Description: Calling NSS-backed functions that support caching via nscd may call the nscd client side code and in the GNU C Library version 2.36 under high load on x86_64 systems, the client may call memcmp on inputs that are concurrently modified by other processes or threads and crash.The nscd client in the GNU C Library uses the memcmp function with inputs that may be concurrently modified by another thread, potentially resulting in spurious cache misses, which in itself is not a security issue. However in the GNU C Library version 2.36 an optimized implementation of memcmp was introduced for x86_64 which could crash when invoked with such undefined behaviour, turning this into a potential crash of the nscd client and the application that uses it. This implementation was backported to the 2.35 branch, making the nscd client in that branch vulnerable as well. Subsequently, the fix for this issue was backported to all vulnerable branches in the GNU C Library repository.It is advised that distributions that may have cherry-picked the memcpy SSE2 optimization in their copy of the GNU C Library, also apply the fix to avoid the potential crash in the nscd client.

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.

These module imports were intentionally deferred to increase startup time of the pip CLI.

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

CVE-2026-5928 Severity: Moderate CVSS3 score: 5.7

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.

CVE-2024-14027 Severity: Moderate CVSS3 score: 5.5

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)").

CVE-2024-27005 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:interconnect: Don't access req_list while it's being manipulatedThe icc_lock mutex was split into separate icc_lock and icc_bw_lockmutexes in [1] to avoid lockdep splats. However, this didn't adequatelyprotect access to icc_node::req_list.The icc_set_bw() function will eventually iterate over req_list whileonly holding icc_bw_lock, but req_list can be modified while onlyholding icc_lock. This causes races between icc_set_bw(), of_icc_get(),and icc_put().Example A: CPU0 CPU1 ---- ---- icc_set_bw(path_a) mutex_lock(&icc_bw_lock); icc_put(path_b) mutex_lock(&icc_lock); aggregate_requests() hlist_for_each_entry(r, ... hlist_del(... Example B: CPU0 CPU1 ---- ---- icc_set_bw(path_a) mutex_lock(&icc_bw_lock); path_b = of_icc_get() of_icc_get_by_index() mutex_lock(&icc_lock); path_find() path_init() aggregate_requests() hlist_for_each_entry(r, ... hlist_add_head(... Fix this by ensuring icc_bw_lock is always held before manipulatingicc_node::req_list. The additional places icc_bw_lock is held don'tperform any memory allocations, so we should still be safe from theoriginal lockdep splats that motivated the separate locks.[1] commit af42269c3523 ("interconnect: Fix locking for runpm vs reclaim")

Since the block group was in the unused list, the used bytesshould be 0 when it was added to the unused list. Then, it checksblock_group->{used,reserved,pinned} are still 0 under theblock_group->lock. So, they should be still eligible for the unused list,not the reclaim list.The reason it is safe there it's because because we're holdingspace_info->groups_sem in write mode.That means no other task can allocate from the block group, so while weare at deleted_unused_bgs() it's not possible for other tasks toallocate and deallocate extents from the block group, so it can't beadded to the unused list or the reclaim list by anyone else.The bug can be reproduced by btrfs/166 after a few rounds. In practicethis can be hit when relocation cannot find more chunk space and endswith ENOSPC.

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

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: mac80211: reject VHT opmode for unsupported channel widthsVHT operating mode notifications are not defined for channel widthsbelow 20 MHz. In particular, 5 MHz and 10 MHz are not valid under theVHT specification and must be rejected.Without this check, malformed notifications using these widths mayreach ieee80211_chan_width_to_rx_bw(), leading to a WARN_ON due toinvalid input. This issue was reported by syzbot.Reject these unsupported widths early in sta_link_apply_parameters()when opmode_notif is used. The accepted set includes 20, 40, 80, 160,and 80+80 MHz, which are valid for VHT. While 320 MHz is not definedfor VHT, it is allowed to avoid rejecting HE or EHT clients that maystill send a VHT opmode notification.

Description: In the Linux kernel, the following vulnerability has been resolved:xfrm: state: initialize state_ptrs earlier in xfrm_state_findIn case of preemption, xfrm_state_look_at will find a differentpcpu_id and look up states for that other CPU. If we matched a statefor CPU2 in the state_cache while the lookup started on CPU1, we willjump to "found", but the "best" state that we got will be ignored andwe will enter the "acquire" block. This block uses state_ptrs, whichisn't initialized at this point.Let's initialize state_ptrs just after taking rcu_read_lock. This willalso prevent a possible misuse in the future, if someone adjusts thisfunction.

CVE-2025-39689 Severity: Moderate CVSS3 score: 5.5

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.

CVE-2025-39748 Severity: Moderate CVSS3 score: 5.5

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-2025-39776 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm/debug_vm_pgtable: clear page table entries at destroy_args()The mm/debug_vm_pagetable test allocates manually page table entries forthe tests it runs, using also its manually allocated mm_struct. That initself is ok, but when it exits, at destroy_args() it fails to clear thoseentries with the *_clear functions.The problem is that leaves stale entries.

At this point, due to the prior trace_iterator_reset, both`iter.seq.len` and `iter.seq.size` were set to 0. Since they are equal,the WARN_ON_ONCE condition is triggered.Move the trace_printk_seq() into the if block that checks to make sure thereturn value of trace_find_next_entry_inc() is non-NULL inftrace_dump_one(), ensuring the 'iter.seq' is properly populated beforesubsequent operations.

Description: In the Linux kernel, the following vulnerability has been resolved:libceph: fix invalid accesses to ceph_connection_v1_infoThere is a place where generic code in messenger.c is reading andanother place where it is writing to con->v1 union member withoutchecking that the union member is active (i.e. msgr1 is in use).On 64-bit systems, con->v1.auth_retry overlaps with con->v2.out_iter,so such a read is almost guaranteed to return a bogus value instead of0 when msgr2 is in use. This ends up being fairly benign because theside effect is just the invalidation of the authorizer and successivefetching of new tickets.con->v1.connect_seq overlaps with con->v2.conn_bufs and the fact thatit's being written to can cause more serious consequences, but luckilyit's not something that happens often.

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

Fix this by directlyreleasing the resources when GuC is not running.Here is the failure dmesg log:"[ 468.089581] ---[ end trace 0000000000000000 ]---[ 468.089608] pci 0000:03:00.0: [drm] *ERROR* GT0: GUC ID manager unclean (1/65535)[ 468.090558] pci 0000:03:00.0: [drm] GT0: total 65535[ 468.090562] pci 0000:03:00.0: [drm] GT0: used 1[ 468.090564] pci 0000:03:00.0: [drm] GT0: range 1..1 (1)[ 468.092716] ------------[ cut here ]------------[ 468.092719] WARNING: CPU: 14 PID: 4775 at drivers/gpu/drm/xe/xe_ttm_vram_mgr.c:298 ttm_vram_mgr_fini+0xf8/0x130 [xe]"v2: use xe_uc_fw_is_running() instead of xe_guc_ct_enabled().

CVE-2025-40181 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:x86/kvm: Force legacy PCI hole to UC when overriding MTRRs for TDX/SNPWhen running as an SNP or TDX guest under KVM, force the legacy PCI hole,i.e. memory between Top of Lower Usable DRAM and 4GiB, to be mapped as UCvia a forced variable MTRR range.In most KVM-based setups, legacy devices such as the HPET and TPM areenumerated via ACPI. ACPI enumeration includes a Memory32Fixed entry, andoptionally a SystemMemory descriptor for an OperationRegion, e.g. if thedevice needs to be accessed via a Control Method.If a SystemMemory entry is present, then the kernel's ACPI driver willauto-ioremap the region so that it can be accessed at will. However, theACPI spec doesn't provide a way to enumerate the memory type ofSystemMemory regions, i.e. there's no way to tell software that a regionmust be mapped as UC vs. WB, etc. As a result, Linux's ACPI driver alwaysmaps SystemMemory regions using ioremap_cache(), i.e. as WB on x86.The dedicated device drivers however, e.g. the HPET driver and TPM driver,want to map their associated memory as UC or WC, as accessing PCI devicesusing WB is unsupported.On bare metal and non-CoCO, the conflicting requirements "work" as firmwareconfigures the PCI hole (and other device memory) to be UC in the MTRRs.So even though the ACPI mappings request WB, they are forced to UC- in thekernel's tracking due to the kernel properly handling the MTRR overrides,and thus are compatible with the drivers' requested WC/UC-.With force WB MTRRs on SNP and TDX guests, the ACPI mappings get theirrequested WB if the ACPI mappings are established before the dedicateddriver code attempts to initialize the device. E.g. if acpi_init()runs before the corresponding device driver is probed, ACPI's WB mappingwill "win", and result in the driver's ioremap() failing because theexisting WB mapping isn't compatible with the requested WC/UC-.E.g. when a TPM is emulated by the hypervisor (ignoring the securityimplications of relying on what is allegedly an untrusted entity to storemeasurements), the TPM driver will request UC and fail: [ 1.730459] ioremap error for 0xfed40000-0xfed45000, requested 0x2, got 0x0 [ 1.732780] tpm_tis MSFT0101:00: probe with driver tpm_tis failed with error -12Note, the '0x2' and '0x0' values refer to "enum page_cache_mode", not x86'smemtypes (which frustratingly are an almost pure inversion; 2 == WB, 0 == UC).E.g. tracing mapping requests for TPM TIS yields: Mapping TPM TIS with req_type = 0 WARNING: CPU: 22 PID: 1 at arch/x86/mm/pat/memtype.c:530 memtype_reserve+0x2ab/0x460 Modules linked in: CPU: 22 UID: 0 PID: 1 Comm: swapper/0 Tainted: G W 6.16.0-rc7+ #2 VOLUNTARY Tainted: [W]=WARN Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 05/29/2025 RIP: 0010:memtype_reserve+0x2ab/0x460 __ioremap_caller+0x16d/0x3d0 ioremap_cache+0x17/0x30 x86_acpi_os_ioremap+0xe/0x20 acpi_os_map_iomem+0x1f3/0x240 acpi_os_map_memory+0xe/0x20 acpi_ex_system_memory_space_handler+0x273/0x440 acpi_ev_address_space_dispatch+0x176/0x4c0 acpi_ex_access_region+0x2ad/0x530 acpi_ex_field_datum_io+0xa2/0x4f0 acpi_ex_extract_from_field+0x296/0x3e0 acpi_ex_read_data_from_field+0xd1/0x460 acpi_ex_resolve_node_to_value+0x2ee/0x530 acpi_ex_resolve_to_value+0x1f2/0x540 acpi_ds_evaluate_name_path+0x11b/0x190 acpi_ds_exec_end_op+0x456/0x960 acpi_ps_parse_loop+0x27a/0xa50 acpi_ps_parse_aml+0x226/0x600 acpi_ps_execute_method+0x172/0x3e0 acpi_ns_evaluate+0x175/0x5f0 acpi_evaluate_object+0x213/0x490 acpi_evaluate_integer+0x6d/0x140 acpi_bus_get_status+0x93/0x150 acpi_add_single_object+0x43a/0x7c0 acpi_bus_check_add+0x149/0x3a0 acpi_bus_check_add_1+0x16/0x30 acpi_ns_walk_namespace+0x22c/0x360 acpi_walk_namespace+0x15c/0x170 acpi_bus_scan+0x1dd/0x200 acpi_scan_init+0xe5/0x2b0 acpi_init+0x264/0x5b0 do_one_i---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:kernel/sys.c: fix the racy usage of task_lock(tsk->group_leader) in sys_prlimit64() pathsThe usage of task_lock(tsk->group_leader) in sys_prlimit64()->do_prlimit()path is very broken.sys_prlimit64() does get_task_struct(tsk) but this only protects task_structitself. If tsk != current and tsk is not a leader, this process can exit/execand task_lock(tsk->group_leader) may use the already freed task_struct.Another problem is that sys_prlimit64() can race with mt-exec which changes->group_leader. In this case do_prlimit() may take the wrong lock, or (worse)->group_leader may change between task_lock() and task_unlock().Change sys_prlimit64() to take tasklist_lock when necessary. This is notnice, but I don't see a better fix for -stable.

Description: In the Linux kernel, the following vulnerability has been resolved:net: openvswitch: remove never-working support for setting nsh fieldsThe validation of the set(nsh(...)) action is completely wrong.It runs through the nsh_key_put_from_nlattr() function that is thesame function that validates NSH keys for the flow match and thepush_nsh() action. However, the set(nsh(...)) has a very differentmemory layout. Nested attributes in there are doubled in size incase of the masked set(). That makes proper validation impossible.There is also confusion in the code between the 'masked' flag, thatsays that the nested attributes are doubled in size containing boththe value and the mask, and the 'is_mask' that says that the valuewe're parsing is the mask. This is causing kernel crash on trying towrite into mask part of the match with SW_FLOW_KEY_PUT() duringvalidation, while validate_nsh() doesn't allocate any memory for it: BUG: kernel NULL pointer dereference, address: 0000000000000018 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 1c2383067 P4D 1c2383067 PUD 20b703067 PMD 0 Oops: Oops: 0000 [#1] SMP NOPTI CPU: 8 UID: 0 Kdump: loaded Not tainted 6.17.0-rc4+ #107 PREEMPT(voluntary) RIP: 0010:nsh_key_put_from_nlattr+0x19d/0x610 [openvswitch] Call Trace: validate_nsh+0x60/0x90 [openvswitch] validate_set.constprop.0+0x270/0x3c0 [openvswitch] __ovs_nla_copy_actions+0x477/0x860 [openvswitch] ovs_nla_copy_actions+0x8d/0x100 [openvswitch] ovs_packet_cmd_execute+0x1cc/0x310 [openvswitch] genl_family_rcv_msg_doit+0xdb/0x130 genl_family_rcv_msg+0x14b/0x220 genl_rcv_msg+0x47/0xa0 netlink_rcv_skb+0x53/0x100 genl_rcv+0x24/0x40 netlink_unicast+0x280/0x3b0 netlink_sendmsg+0x1f7/0x430 ____sys_sendmsg+0x36b/0x3a0 ___sys_sendmsg+0x87/0xd0 __sys_sendmsg+0x6d/0xd0 do_syscall_64+0x7b/0x2c0 entry_SYSCALL_64_after_hwframe+0x76/0x7eThe third issue with this process is that while trying to convertthe non-masked set into masked one, validate_set() copies and doublesthe size of the OVS_KEY_ATTR_NSH as if it didn't have any nestedattributes. It should be copying each nested attribute and doublingthem in size independently. And the process must be properly reversedduring the conversion back from masked to a non-masked variant duringthe flow dump.In the end, the only two outcomes of trying to use this action areeither validation failure or a kernel crash. And if somehow someonemanages to install a flow with such an action, it will most definitelynot do what it is supposed to, since all the keys and the masks aremixed up.Fixing all the issues is a complex task as it requires re-writingmost of the validation code.Given that and the fact that this functionality never worked sinceintroduction, let's just remove it altogether. It's better tore-introduce it later with a proper implementation instead of tryingto fix it in stable releases.

CVE-2025-40341 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-2025-40350 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5e: RX, Fix generating skb from non-linear xdp_buff for striding RQXDP programs can change the layout of an xdp_buff throughbpf_xdp_adjust_tail() and bpf_xdp_adjust_head(). Therefore, the drivercannot assume the size of the linear data area nor fragments. Fix thebug in mlx5 by generating skb according to xdp_buff after XDP programsrun.Currently, when handling multi-buf XDP, the mlx5 driver assumes thelayout of an xdp_buff to be unchanged. That is, the linear data areacontinues to be empty and fragments remain the same. This may causethe driver to generate erroneous skb or triggering a kernelwarning. When an XDP program added linear data throughbpf_xdp_adjust_head(), the linear data will be ignored asmlx5e_build_linear_skb() builds an skb without linear data and thenpull data from fragments to fill the linear data area. When an XDPprogram has shrunk the non-linear data through bpf_xdp_adjust_tail(),the delta passed to __pskb_pull_tail() may exceed the actual nonlineardata size and trigger the BUG_ON in it.To fix the issue, first record the original number of fragments. If thenumber of fragments changes after the XDP program runs, rewind the endfragment pointer by the difference and recalculate the truesize. Then,build the skb with the linear data area matching the xdp_buff. Finally,only pull data in if there is non-linear data and fill the linear partup to 256 bytes.

CVE-2025-68179 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:s390: Disable ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAPAs reported by Luiz Capitulino enabling HVO on s390 leads to reproduciblecrashes. The problem is that kernel page tables are modified withoutflushing corresponding TLB entries.Even if it looks like the empty flush_tlb_all() implementation on s390 isthe problem, it is actually a different problem: on s390 it is not allowedto replace an active/valid page table entry with another valid page tableentry without the detour over an invalid entry. A direct replacement maylead to random crashes and/or data corruption.In order to invalidate an entry special instructions have to be used(e.g. ipte or idte). Alternatively there are also special instructionsavailable which allow to replace a valid entry with a different validentry (e.g. crdte or cspg).Given that the HVO code currently does not provide the hooks to allow foran implementation which is compliant with the s390 architecturerequirements, disable ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAP again, which isbasically a revert of the original patch which enabled it.

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:cifs: fix memory leak in smb3_fs_context_parse_param error pathAdd proper cleanup of ctx->source and fc->source to thecifs_parse_mount_err error handler. This ensures that memory allocatedfor the source strings is correctly freed on all error paths, matchingthe cleanup already performed in the success path bysmb3_cleanup_fs_context_contents().Pointers are also set to NULL after freeing to prevent potentialdouble-free issues.This change fixes a memory leak originally detected by syzbot. Theleak occurred when processing Opt_source mount options if an errorhappened after ctx->source and fc->source were successfullyallocated but before the function completed.The specific leak sequence was:1. ctx->source = smb3_fs_context_fullpath(ctx, '/') allocates memory2. fc->source = kstrdup(ctx->source, GFP_KERNEL) allocates more memory3. A subsequent error jumps to cifs_parse_mount_err4. The old error handler freed passwords but not the source strings,causing the memory to leak.This issue was not addressed by commit e8c73eb7db0a ("cifs: client:fix memory leak in smb3_fs_context_parse_param"), which only fixedleaks from repeated fsconfig() calls but not this error path.Patch updated with minor change suggested by kernel test robot

Description: In the Linux kernel, the following vulnerability has been resolved: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:staging: rtl8723bs: fix out-of-bounds read in rtw_get_ie() parserThe Information Element (IE) parser rtw_get_ie() trusted the lengthbyte of each IE without validating that the IE body (len bytes afterthe 2-byte header) fits inside the remaining frame buffer. A malformedframe can advertise an IE length larger than the available data, causingthe parser to increment its pointer beyond the buffer end. This resultsin out-of-bounds reads or, depending on the pattern, an infinite loop.Fix by validating that (offset + 2 + len) does not exceed the limitbefore accepting the IE or advancing to the next element.This prevents OOB reads and ensures the parser terminates safely onmalformed frames.

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.

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.

CVE-2025-68301 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: atlantic: fix fragment overflow handling in RX pathThe atlantic driver can receive packets with more than MAX_SKB_FRAGS (17)fragments when handling large multi-descriptor packets. This causes anout-of-bounds write in skb_add_rx_frag_netmem() leading to kernel panic.The issue occurs because the driver doesn't check the total number offragments before calling skb_add_rx_frag(). When a packet requires morethan MAX_SKB_FRAGS fragments, the fragment index exceeds the array bounds.Fix by assuming there will be an extra frag if buff->len > AQ_CFG_RX_HDR_SIZE,then all fragments are accounted for. And reusing the existing check toprevent the overflow earlier in the code path.This crash occurred in production with an Aquantia AQC113 10G NIC.Stack trace from production environment:```RIP: 0010:skb_add_rx_frag_netmem+0x29/0xd0Code: 90 f3 0f 1e fa 0f 1f 44 00 00 48 89 f8 41 89ca 48 89 d7 48 63 ce 8b 90 c0 00 00 00 48 c1 e1 04 48 01 ca 48 03 90c8 00 00 00 <48> 89 7a 30 44 89 52 3c 44 89 42 38 40 f6 c7 01 75 74 4889 fa 83RSP: 0018:ffffa9bec02a8d50 EFLAGS: 00010287RAX: ffff925b22e80a00 RBX: ffff925ad38d2700 RCX:fffffffe0a0c8000RDX: ffff9258ea95bac0 RSI: ffff925ae0a0c800 RDI:0000000000037a40RBP: 0000000000000024 R08: 0000000000000000 R09:0000000000000021R10: 0000000000000848 R11: 0000000000000000 R12:ffffa9bec02a8e24R13: ffff925ad8615570 R14: 0000000000000000 R15:ffff925b22e80a00FS: 0000000000000000(0000)GS:ffff925e47880000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: ffff9258ea95baf0 CR3: 0000000166022004 CR4:0000000000f72ef0PKRU: 55555554Call Trace:aq_ring_rx_clean+0x175/0xe60 [atlantic]? aq_ring_rx_clean+0x14d/0xe60 [atlantic]? aq_ring_tx_clean+0xdf/0x190 [atlantic]? kmem_cache_free+0x348/0x450? aq_vec_poll+0x81/0x1d0 [atlantic]? __napi_poll+0x28/0x1c0? net_rx_action+0x337/0x420```Changes in v4:- Add Fixes: tag to satisfy patch validation requirements.Changes in v3:- Fix by assuming there will be an extra frag if buff->len > AQ_CFG_RX_HDR_SIZE, then all fragments are accounted for.

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: hci_core: lookup hci_conn on RX path on protocol sideThe hdev lock/lookup/unlock/use pattern in the packet RX path doesn'tensure hci_conn* is not concurrently modified/deleted. This lockingappears to be leftover from before conn_hash started using RCUcommit bf4c63252490b ("Bluetooth: convert conn hash to RCU")and not clear if it had purpose since then.Currently, there are code paths that delete hci_conn* from elsewherethan the ordered hdev->workqueue where the RX work runs in. E.g.commit 5af1f84ed13a ("Bluetooth: hci_sync: Fix UAF on hci_abort_conn_sync")introduced some of these, and there probably were a few others beforeit. It's better to do the locking so that even if these runconcurrently no UAF is possible.Move the lookup of hci_conn and associated socket-specific conn toprotocol recv handlers, and do them within a single critical sectionto cover hci_conn* usage and lookup.syzkaller has reported a crash that appears to be this issue: [Task hdev->workqueue] [Task 2] hci_disconnect_all_sync l2cap_recv_acldata(hcon) hci_conn_get(hcon) hci_abort_conn_sync(hcon) hci_dev_lock hci_dev_lock hci_conn_del(hcon) v-------------------------------- hci_dev_unlock hci_conn_put(hcon) conn = hcon->l2cap_data (UAF)

CVE-2025-68325 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: sch_cake: Fix incorrect qlen reduction in cake_dropIn cake_drop(), qdisc_tree_reduce_backlog() is used to update the qlenand backlog of the qdisc hierarchy. Its caller, cake_enqueue(), assumesthat the parent qdisc will enqueue the current packet. However, thisassumption breaks when cake_enqueue() returns NET_XMIT_CN: the parentqdisc stops enqueuing current packet, leaving the tree qlen/backlogaccounting inconsistent. This mismatch can lead to a NULL dereference(e.g., when the parent Qdisc is qfq_qdisc).This patch computes the qlen/backlog delta in a more robust way byobserving the difference before and after the series of cake_drop()calls, and then compensates the qdisc tree accounting if cake_enqueue()returns NET_XMIT_CN.To ensure correct compensation when ACK thinning is enabled, a newvariable is introduced to keep qlen unchanged.

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---

CVE-2025-68725 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Do not let BPF test infra emit invalid GSO types to stackYinhao et al. reported that their fuzzer tool was able to trigger askb_warn_bad_offload() from netif_skb_features() -> gso_features_check().When a BPF program - triggered via BPF test infra - pushes the packetto the loopback device via bpf_clone_redirect() then mentioned offloadwarning can be seen. GSO-related features are then rightfully disabled.We get into this situation due to convert___skb_to_skb() settinggso_segs and gso_size but not gso_type. Technically, it makes sensethat this warning triggers since the GSO properties are malformed dueto the gso_type. Potentially, the gso_type could be marked non-trustworthythrough setting it at least to SKB_GSO_DODGY without any other specificassumptions, but that also feels wrong given we should not go furtherinto the GSO engine in the first place.The checks were added in 121d57af308d ("gso: validate gso_type in GSOhandlers") because there were malicious (syzbot) senders that combinea protocol with a non-matching gso_type. If we would want to drop suchpackets, gso_features_check() currently only returns feature flags vianetif_skb_features(), so one location for potentially dropping such skbscould be validate_xmit_unreadable_skb(), but then otoh it would bean additional check in the fast-path for a very corner case. Givenbpf_clone_redirect() is the only place where BPF test infra could emitsuch packets, lets reject them right there.

CVE-2025-68780 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.

Unbinding on a FLAGS_ONLYchange is easy enough, and can/will be done as a hardening measure (inanticipation of KVM supporting dirty logging on guest_memfd at some point),but fixing the use-after-free would only address the immediate symptom. ================================================================== BUG: KASAN: slab-use-after-free in kvm_gmem_release+0x362/0x400 [kvm] Write of size 8 at addr ffff8881111ae908 by task repro/745 CPU: 7 UID: 1000 PID: 745 Comm: repro Not tainted 6.18.0-rc6-115d5de2eef3-next-kasan #3 NONE Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 Call Trace: dump_stack_lvl+0x51/0x60 print_report+0xcb/0x5c0 kasan_report+0xb4/0xe0 kvm_gmem_release+0x362/0x400 [kvm] __fput+0x2fa/0x9d0 task_work_run+0x12c/0x200 do_exit+0x6ae/0x2100 do_group_exit+0xa8/0x230 __x64_sys_exit_group+0x3a/0x50 x64_sys_call+0x737/0x740 do_syscall_64+0x5b/0x900 entry_SYSCALL_64_after_hwframe+0x4b/0x53 RIP: 0033:0x7f581f2eac31 Allocated by task 745 on cpu 6 at 9.746971s: kasan_save_stack+0x20/0x40 kasan_save_track+0x13/0x50 __kasan_kmalloc+0x77/0x90 kvm_set_memory_region.part.0+0x652/0x1110 [kvm] kvm_vm_ioctl+0x14b0/0x3290 [kvm] __x64_sys_ioctl+0x129/0x1a0 do_syscall_64+0x5b/0x900 entry_SYSCALL_64_after_hwframe+0x4b/0x53 Freed by task 745 on cpu 6 at 9.747467s: kasan_save_stack+0x20/0x40 kasan_save_track+0x13/0x50 __kasan_save_free_info+0x37/0x50 __kasan_slab_free+0x3b/0x60 kfree+0xf5/0x440 kvm_set_memslot+0x3c2/0x1160 [kvm] kvm_set_memory_region.part.0+0x86a/0x1110 [kvm] kvm_vm_ioctl+0x14b0/0x3290 [kvm] __x64_sys_ioctl+0x129/0x1a0 do_syscall_64+0x5b/0x900 entry_SYSCALL_64_after_hwframe+0x4b/0x53

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring: fix filename leak in __io_openat_prep() __io_openat_prep() allocates a struct filename using getname(). However,for the condition of the file being installed in the fixed file table aswell as having O_CLOEXEC flag set, the function returns early. At thatpoint, the request doesn't have REQ_F_NEED_CLEANUP flag set. Due to this,the memory for the newly allocated struct filename is not cleaned up,causing a memory leak.Fix this by setting the REQ_F_NEED_CLEANUP for the request just after thesuccessful getname() call, so that when the request is torn down, thefilename will be cleaned up, along with other resources needing cleanup.

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.

This preloadcache is subject to periodic eviction - typically after every 256 contextswitches - to remove old entry.To optimize performance, the kernel skips switch_mmu_context() inswitch_mm_irqs_off() when the prev and next mm_struct are the same.However, on hash MMU systems, this can lead to inconsistencies betweenthe hardware SLB and the software preload cache.If an SLB entry for a process is evicted from the software cache on oneCPU, and the same process later runs on another CPU without executingswitch_mmu_context(), the hardware SLB may retain stale entries. If thekernel then attempts to reload that entry, it can trigger an SLBmulti-hit error.The following timeline shows how stale SLB entries are created and cancause a multi-hit error when a process moves between CPUs without aMMU context switch.CPU 0 CPU 1----- -----Process Pexec swapper/1 load_elf_binary begin_new_exc activate_mm switch_mm_irqs_off switch_mmu_context switch_slb /* * This invalidates all * the entries in the HW * and setup the new HW * SLB entries as per the * preload cache. */context_switchsched_migrate_task migrates process P to cpu-1Process swapper/0 context switch (to process P)(uses mm_struct of Process P) switch_mm_irqs_off() switch_slb load_slb++ /* * load_slb becomes 0 here * and we evict an entry from * the preload cache with * preload_age().

Description: In the Linux kernel, the following vulnerability has been resolved: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.

Description: In the Linux kernel, the following vulnerability has been resolved:hwmon: (w83791d) Convert macros to functions to avoid TOCTOUThe macro FAN_FROM_REG evaluates its arguments multiple times. When usedin lockless contexts involving shared driver data, this leads toTime-of-Check to Time-of-Use (TOCTOU) race conditions, potentiallycausing divide-by-zero errors.Convert the macro to a static function. This guarantees that argumentsare evaluated only once (pass-by-value), preventing the raceconditions.Additionally, in store_fan_div, move the calculation of the minimumlimit inside the update lock. This ensures that the read-modify-writesequence operates on consistent data.Adhere to the principle of minimal changes by only converting macrosthat evaluate arguments multiple times and are used in locklesscontexts.

CVE-2025-71127 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: mac80211: Discard Beacon frames to non-broadcast addressBeacon frames are required to be sent to the broadcast address, see IEEEStd 802.11-2020, 11.1.3.1 ("The Address 1 field of the Beacon .. frameshall be set to the broadcast address"). A unicast Beacon frame might beused as a targeted attack to get one of the associated STAs to dosomething (e.g., using CSA to move it to another channel). As such, itis better have strict filtering for this on the received side anddiscard all Beacon frames that are sent to an unexpected address.This is even more important for cases where beacon protection is used.The current implementation in mac80211 is correctly discarding unicastBeacon frames if the Protected Frame bit in the Frame Control field isset to 0. However, if that bit is set to 1, the logic used for checkingfor configured BIGTK(s) does not actually work. If the driver does nothave logic for dropping unicast Beacon frames with Protected Frame bit1, these frames would be accepted in mac80211 processing as valid Beaconframes even though they are not protected. This would allow beaconprotection to be bypassed. While the logic for checking beaconprotection could be extended to cover this corner case, a more genericcheck for discard all Beacon frames based on A1=unicast address coversthis without needing additional changes.Address all these issues by dropping received Beacon frames if they aresent to a non-broadcast address.

CVE-2025-71130 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:drm/i915/gem: Zero-initialize the eb.vma array in i915_gem_do_execbufferInitialize the eb.vma array with values of 0 when the eb structure isfirst set up. In particular, this sets the eb->vma[i].vma pointers toNULL, simplifying cleanup and getting rid of the bug described below.During the execution of eb_lookup_vmas(), the eb->vma array issuccessively filled up with struct eb_vma objects. This process includescalling eb_add_vma(), which might fail; however, even in the event offailure, eb->vma[i].vma is set for the currently processed buffer.If eb_add_vma() fails, eb_lookup_vmas() returns with an error, whichprompts a call to eb_release_vmas() to clean up the mess. Sinceeb_lookup_vmas() might fail during processing any (possibly not first)buffer, eb_release_vmas() checks whether a buffer's vma is NULL to knowat what point did the lookup function fail.In eb_lookup_vmas(), eb->vma[i].vma is set to NULL if either the helperfunction eb_lookup_vma() or eb_validate_vma() fails. eb->vma[i+1].vma isset to NULL in case i915_gem_object_userptr_submit_init() fails; thecurrent one needs to be cleaned up by eb_release_vmas() at this point,so the next one is set. If eb_add_vma() fails, neither the current northe next vma is set to NULL, which is a source of a NULL deref bugdescribed in the issue linked in the Closes tag.When entering eb_lookup_vmas(), the vma pointers are set to the slabpoison value, instead of NULL. This doesn't matter for the actuallookup, since it gets overwritten anyway, however the eb_release_vmas()function only recognizes NULL as the stopping value, hence the pointersare being set to NULL as they go in case of intermediate failure. Thispatch changes the approach to filling them all with NULL at the startinstead, rather than handling that manually during failure.(cherry picked from commit 08889b706d4f0b8d2352b7ca29c2d8df4d0787cd)

Description: In the Linux kernel, the following vulnerability has been resolved:md/raid5: fix possible null-pointer dereferences in raid5_store_group_thread_cnt()The variable mddev->private is first assigned to conf and then checked: conf = mddev->private; if (!conf) ...If conf is NULL, then mddev->private is also NULL. In this case,null-pointer dereferences can occur when calling raid5_quiesce(): raid5_quiesce(mddev, true); raid5_quiesce(mddev, false);since mddev->private is assigned to conf again in raid5_quiesce(), and confis dereferenced in several places, for example: conf->quiesce = 0; wake_up(&conf->wait_for_quiescent);To fix this issue, the function should unlock mddev and return beforeinvoking raid5_quiesce() when conf is NULL, following the existing patternin raid5_change_consistency_policy().

CVE-2025-71162 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:dmaengine: tegra-adma: Fix use-after-freeA use-after-free bug exists in the Tegra ADMA driver when audio streamsare terminated, particularly during XRUN conditions. The issue occurswhen the DMA buffer is freed by tegra_adma_terminate_all() before thevchan completion tasklet finishes accessing it.The race condition follows this sequence: 1. DMA transfer completes, triggering an interrupt that schedules the completion tasklet (tasklet has not executed yet) 2. Audio playback stops, calling tegra_adma_terminate_all() which frees the DMA buffer memory via kfree() 3. The scheduled tasklet finally executes, calling vchan_complete() which attempts to access the already-freed memorySince tasklets can execute at any time after being scheduled, there isno guarantee that the buffer will remain valid when vchan_complete()runs.Fix this by properly synchronizing the virtual channel completion: - Calling vchan_terminate_vdesc() in tegra_adma_stop() to mark the descriptors as terminated instead of freeing the descriptor. - Add the callback tegra_adma_synchronize() that calls vchan_synchronize() which kills any pending tasklets and frees any terminated descriptors.Crash logs:[ 337.427523] BUG: KASAN: use-after-free in vchan_complete+0x124/0x3b0[ 337.427544] Read of size 8 at addr ffff000132055428 by task swapper/0/0[ 337.427562] Call trace:[ 337.427564] dump_backtrace+0x0/0x320[ 337.427571] show_stack+0x20/0x30[ 337.427575] dump_stack_lvl+0x68/0x84[ 337.427584] print_address_description.constprop.0+0x74/0x2b8[ 337.427590] kasan_report+0x1f4/0x210[ 337.427598] __asan_load8+0xa0/0xd0[ 337.427603] vchan_complete+0x124/0x3b0[ 337.427609] tasklet_action_common.constprop.0+0x190/0x1d0[ 337.427617] tasklet_action+0x30/0x40[ 337.427623] __do_softirq+0x1a0/0x5c4[ 337.427628] irq_exit+0x110/0x140[ 337.427633] handle_domain_irq+0xa4/0xe0[ 337.427640] gic_handle_irq+0x64/0x160[ 337.427644] call_on_irq_stack+0x20/0x4c[ 337.427649] do_interrupt_handler+0x7c/0x90[ 337.427654] el1_interrupt+0x30/0x80[ 337.427659] el1h_64_irq_handler+0x18/0x30[ 337.427663] el1h_64_irq+0x7c/0x80[ 337.427667] cpuidle_enter_state+0xe4/0x540[ 337.427674] cpuidle_enter+0x54/0x80[ 337.427679] do_idle+0x2e0/0x380[ 337.427685] cpu_startup_entry+0x2c/0x70[ 337.427690] rest_init+0x114/0x130[ 337.427695] arch_call_rest_init+0x18/0x24[ 337.427702] start_kernel+0x380/0x3b4[ 337.427706] __primary_switched+0xc0/0xc8

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: always detect conflicting inodes when logging inode refsAfter rename exchanging (either with the rename exchange operation orregular renames in multiple non-atomic steps) two inodes and at leastone of them is a directory, we can end up with a log tree that containsonly of the inodes and after a power failure that can result in an attemptto delete the other inode when it should not because it was not deletedbefore the power failure. In some case that delete attempt fails whenthe target inode is a directory that contains a subvolume inside it, sincethe log replay code is not prepared to deal with directory entries thatpoint to root items (only inode items).1) We have directories "dir1" (inode A) and "dir2" (inode B) under the same parent directory;2) We have a file (inode C) under directory "dir1" (inode A);3) We have a subvolume inside directory "dir2" (inode B);4) All these inodes were persisted in a past transaction and we are currently at transaction N;5) We rename the file (inode C), so at btrfs_log_new_name() we update inode C's last_unlink_trans to N;6) We get a rename exchange for "dir1" (inode A) and "dir2" (inode B), so after the exchange "dir1" is inode B and "dir2" is inode A. During the rename exchange we call btrfs_log_new_name() for inodes A and B, but because they are directories, we don't update their last_unlink_trans to N;7) An fsync against the file (inode C) is done, and because its inode has a last_unlink_trans with a value of N we log its parent directory (inode A) (through btrfs_log_all_parents(), called from btrfs_log_inode_parent()).8) So we end up with inode B not logged, which now has the old name of inode A. At copy_inode_items_to_log(), when logging inode A, we did not check if we had any conflicting inode to log because inode A has a generation lower than the current transaction (created in a past transaction);9) After a power failure, when replaying the log tree, since we find that inode A has a new name that conflicts with the name of inode B in the fs tree, we attempt to delete inode B... this is wrong since that directory was never deleted before the power failure, and because there is a subvolume inside that directory, attempting to delete it will fail since replay_dir_deletes() and btrfs_unlink_inode() are not prepared to deal with dir items that point to roots instead of inodes.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:phy: stm32-usphyc: Fix off by one in probe()The "index" variable is used as an index into the usbphyc->phys[] arraywhich has usbphyc->nphys elements. So if it is equal to usbphyc->nphysthen it is one element out of bounds. The "index" comes from thedevice tree so it's data that we trust and it's unlikely to be wrong,however it's obviously still worth fixing the bug. Change the > to >=.

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---

Description: In the Linux kernel, the following vulnerability has been resolved:net: mscc: ocelot: Fix crash when adding interface under a lagCommit 15faa1f67ab4 ("lan966x: Fix crash when adding interface under a lag")fixed a similar issue in the lan966x driver caused by a NULL pointer dereference.The ocelot_set_aggr_pgids() function in the ocelot driver has similar logicand is susceptible to the same crash.This issue specifically affects the ocelot_vsc7514.c frontend, which leavesunused ports as NULL pointers. The felix_vsc9959.c frontend is unaffected asit uses the DSA framework which registers all ports.Fix this by checking if the port pointer is valid before accessing it.

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.

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:uacce: ensure safe queue release with state managementDirectly calling `put_queue` carries risks since it cannotguarantee that resources of `uacce_queue` have been fully releasedbeforehand. So adding a `stop_queue` operation for theUACCE_CMD_PUT_Q command and leaving the `put_queue` operation tothe final resource release ensures safety.Queue states are defined as follows:- UACCE_Q_ZOMBIE: Initial state- UACCE_Q_INIT: After opening `uacce`- UACCE_Q_STARTED: After `start` is issued via `ioctl`When executing `poweroff -f` in virt while accelerator are stillworking, `uacce_fops_release` and `uacce_remove` may executeconcurrently. This can cause `uacce_put_queue` within`uacce_fops_release` to access a NULL `ops` pointer. Therefore, addstate checks to prevent accessing freed pointers.

CVE-2026-23073 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: rsi: Fix memory corruption due to not set vif driver data sizeThe struct ieee80211_vif contains trailing space for vif driver data,when struct ieee80211_vif is allocated, the total memory size that isallocated is sizeof(struct ieee80211_vif) + size of vif driver data.The size of vif driver data is set by each WiFi driver as needed.The RSI911x driver does not set vif driver data size, no trailing spacefor vif driver data is therefore allocated past struct ieee80211_vif .The RSI911x driver does however use the vif driver data to store itsvif driver data structure "struct vif_priv". An access to vif->drv_privleads to access out of struct ieee80211_vif bounds and corruption ofsome memory.In case of the failure observed locally, rsi_mac80211_add_interface()would write struct vif_priv *vif_info = (struct vif_priv *)vif->drv_priv;vif_info->vap_id = vap_idx. This write corrupts struct fq_tin memberstruct list_head new_flows . The flow = list_first_entry(head, structfq_flow, flowchain); in fq_tin_reset() then reports non-NULL bogusaddress, which when accessed causes a crash.The trigger is very simple, boot the machine with init=/bin/sh , mountdevtmpfs, sysfs, procfs, and then do "ip link set wlan0 up", "sleep 1","ip link set wlan0 down" and the crash occurs.Fix this by setting the correct size of vif driver data, which is thesize of "struct vif_priv", so that memory is allocated and the drivercan store its driver data in it, instead of corrupting memory aroundit.

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.

It triggers the"stack" synthetic event that has a stacktrace as its field (called "stack"). ~# echo 's:syscall_stack s64 id; unsigned long stack[];' >> dynamic_events ~# echo 'hist:keys=common_pid:s2=stack' >> events/synthetic/stack/trigger ~# echo 'hist:keys=common_pid:s3=$s2,i0=id:onmatch(synthetic.stack).trace(syscall_stack,$i0,$s3)' >> events/raw_syscalls/sys_exit/triggerThe above makes another synthetic event called "syscall_stack" thatattaches the first synthetic event (stack) to the sys_exit trace event andrecords the stacktrace from the stack event with the id of the system callthat is exiting.When enabling this event (or using it in a historgram): ~# echo 1 > events/synthetic/syscall_stack/enableProduces a kernel crash!

Description: In the Linux kernel, the following vulnerability has been resolved:uacce: fix isolate sysfs check conditionuacce supports the device isolation feature. If the driverimplements the isolate_err_threshold_read andisolate_err_threshold_write callback functions, uacce will createsysfs files now. Users can read and configure the isolation policythrough sysfs. Currently, sysfs files are created as long as eitherisolate_err_threshold_read or isolate_err_threshold_write callbackfunctions are present.However, accessing a non-existent callback function may cause thesystem to crash. Therefore, intercept the creation of sysfs ifneither read nor write exists; create sysfs if either is supported,but intercept unsupported operations at the call site.

CVE-2026-23102 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:arm64/fpsimd: signal: Fix restoration of SVE contextWhen SME is supported, Restoring SVE signal context can go wrong in afew ways, including placing the task into an invalid state where thekernel may read from out-of-bounds memory (and may potentially take afatal fault) and/or may kill the task with a SIGKILL.(1) Restoring a context with SVE_SIG_FLAG_SM set can place the task into an invalid state where SVCR.SM is set (and sve_state is non-NULL) but TIF_SME is clear, consequently resuting in out-of-bounds memory reads and/or killing the task with SIGKILL. This can only occur in unusual (but legitimate) cases where the SVE signal context has either been modified by userspace or was saved in the context of another task (e.g. as with CRIU), as otherwise the presence of an SVE signal context with SVE_SIG_FLAG_SM implies that TIF_SME is already set. While in this state, task_fpsimd_load() will NOT configure SMCR_ELx (leaving some arbitrary value configured in hardware) before restoring SVCR and attempting to restore the streaming mode SVE registers from memory via sve_load_state(). As the value of SMCR_ELx.LEN may be larger than the task's streaming SVE vector length, this may read memory outside of the task's allocated sve_state, reading unrelated data and/or triggering a fault. While this can result in secrets being loaded into streaming SVE registers, these values are never exposed. As TIF_SME is clear, fpsimd_bind_task_to_cpu() will configure CPACR_ELx.SMEN to trap EL0 accesses to streaming mode SVE registers, so these cannot be accessed directly at EL0. As fpsimd_save_user_state() verifies the live vector length before saving (S)SVE state to memory, no secret values can be saved back to memory (and hence cannot be observed via ptrace, signals, etc). When the live vector length doesn't match the expected vector length for the task, fpsimd_save_user_state() will send a fatal SIGKILL signal to the task. Hence the task may be killed after executing userspace for some period of time.(2) Restoring a context with SVE_SIG_FLAG_SM clear does not clear the task's SVCR.SM. If SVCR.SM was set prior to restoring the context, then the task will be left in streaming mode unexpectedly, and some register state will be combined inconsistently, though the task will be left in legitimate state from the kernel's PoV. This can only occur in unusual (but legitimate) cases where ptrace has been used to set SVCR.SM after entry to the sigreturn syscall, as syscall entry clears SVCR.SM. In these cases, the the provided SVE register data will be loaded into the task's sve_state using the non-streaming SVE vector length and the FPSIMD registers will be merged into this using the streaming SVE vector length.Fix (1) by setting TIF_SME when setting SVCR.SM. This also requiresensuring that the task's sme_state has been allocated, but as this couldcontain live ZA state, it should not be zeroed. Fix (2) by clearingSVCR.SM when restoring a SVE signal context with SVE_SIG_FLAG_SM clear.For consistency, I've pulled the manipulation of SVCR, TIF_SVE, TIF_SME,and fp_type earlier, immediately after the allocation ofsve_state/sme_state, before the restore of the actual register state.This makes it easier to ensure that these are always modifiedconsistently, even if a fault is taken while reading the register datafrom the signal context. I do not expect any software to depend on theexact state restored when a fault is taken while reading the context.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:arm64/fpsimd: signal: Allocate SSVE storage when restoring ZAThe code to restore a ZA context doesn't attempt to allocate the task'ssve_state before setting TIF_SME. Consequently, restoring a ZA contextcan place a task into an invalid state where TIF_SME is set but thetask's sve_state is NULL.In legitimate but uncommon cases where the ZA signal context was NOTcreated by the kernel in the context of the same task (e.g. if the taskis saved/restored with something like CRIU), we have no guarantee thatsve_state had been allocated previously. In these cases, userspace canenter streaming mode without trapping while sve_state is NULL, causing alater NULL pointer dereference when the kernel attempts to store theregister state:| # ./sigreturn-za| Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000| Mem abort info:| ESR = 0x0000000096000046| EC = 0x25: DABT (current EL), IL = 32 bits| SET = 0, FnV = 0| EA = 0, S1PTW = 0| FSC = 0x06: level 2 translation fault| Data abort info:| ISV = 0, ISS = 0x00000046, ISS2 = 0x00000000| CM = 0, WnR = 1, TnD = 0, TagAccess = 0| GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0| user pgtable: 4k pages, 52-bit VAs, pgdp=0000000101f47c00| [0000000000000000] pgd=08000001021d8403, p4d=0800000102274403, pud=0800000102275403, pmd=0000000000000000| Internal error: Oops: 0000000096000046 [#1] SMP| Modules linked in:| CPU: 0 UID: 0 PID: 153 Comm: sigreturn-za Not tainted 6.19.0-rc1 #1 PREEMPT| Hardware name: linux,dummy-virt (DT)| pstate: 214000c9 (nzCv daIF +PAN -UAO -TCO +DIT -SSBS BTYPE=--)| pc : sve_save_state+0x4/0xf0| lr : fpsimd_save_user_state+0xb0/0x1c0| sp : ffff80008070bcc0| x29: ffff80008070bcc0 x28: fff00000c1ca4c40 x27: 63cfa172fb5cf658| x26: fff00000c1ca5228 x25: 0000000000000000 x24: 0000000000000000| x23: 0000000000000000 x22: fff00000c1ca4c40 x21: fff00000c1ca4c40| x20: 0000000000000020 x19: fff00000ff6900f0 x18: 0000000000000000| x17: fff05e8e0311f000 x16: 0000000000000000 x15: 028fca8f3bdaf21c| x14: 0000000000000212 x13: fff00000c0209f10 x12: 0000000000000020| x11: 0000000000200b20 x10: 0000000000000000 x9 : fff00000ff69dcc0| x8 : 00000000000003f2 x7 : 0000000000000001 x6 : fff00000c1ca5b48| x5 : fff05e8e0311f000 x4 : 0000000008000000 x3 : 0000000000000000| x2 : 0000000000000001 x1 : fff00000c1ca5970 x0 : 0000000000000440| Call trace:| sve_save_state+0x4/0xf0 (P)| fpsimd_thread_switch+0x48/0x198| __switch_to+0x20/0x1c0| __schedule+0x36c/0xce0| schedule+0x34/0x11c| exit_to_user_mode_loop+0x124/0x188| el0_interrupt+0xc8/0xd8| __el0_irq_handler_common+0x18/0x24| el0t_64_irq_handler+0x10/0x1c| el0t_64_irq+0x198/0x19c| Code: 54000040 d51b4408 d65f03c0 d503245f (e5bb5800)| ---[ end trace 0000000000000000 ]---Fix this by having restore_za_context() ensure that the task's sve_stateis allocated, matching what we do when taking an SME trap.

CVE-2026-23113 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring/io-wq: check IO_WQ_BIT_EXIT inside work run loopCurrently this is checked before running the pending work. Normally thisis quite fine, as work items either end up blocking (which will create anew worker for other items), or they complete fairly quickly. But syzbotreports an issue where io-wq takes seemingly forever to exit, and with abit of debugging, this turns out to be because it queues a bunch of big(2GB - 4096b) reads with a /dev/msr* file. Since this file type doesn'tsupport ->read_iter(), loop_rw_iter() ends up handling them. Each readreturns 16MB of data read, which takes 20 (!!) seconds. With a bunch ofthese pending, processing the whole chain can take a long time. Easilylonger than the syzbot uninterruptible sleep timeout of 140 seconds.This then triggers a complaint off the io-wq exit path:INFO: task syz.4.135:6326 blocked for more than 143 seconds.

However, we can speed up the exit by checking theIO_WQ_BIT_EXIT inside the io_worker_handle_work() loop, as syzbot willexit the ring after queueing up all of these reads. Then once the firstitem is processed, io-wq will simply cancel the rest. That should avoidsyzbot running into this complaint again.

This allows a DATA chunk with auth = 1 and shkey = NULLto be queued by sctp_datamsg_from_user().Since command interpretation stops on failure, no COOKIE_ECHO should beensent via SCTP_CMD_GEN_COOKIE_ECHO. However, the T1_COOKIE timer has alreadybeen started, and it may enqueue a COOKIE_ECHO into the outqueue later. Asa result, the DATA chunk can be transmitted together with the COOKIE_ECHOin sctp_outq_flush_data(), leading to the observed issue.Similar to the other places where it calls sctp_auth_asoc_init_active_key()right after sctp_process_init(), this patch moves the SCTP_CMD_ASSOC_SHKEYimmediately after SCTP_CMD_PEER_INIT, before stopping T1_INIT and startingT1_COOKIE. This ensures that if shared key generation fails, authenticatedDATA cannot be sent. It also allows the T1_INIT timer to retransmit INIT,giving the client another chance to process INIT_ACK and retry key setup.

Description: In the Linux kernel, the following vulnerability has been resolved:arm64: Set __nocfi on swsusp_arch_resume()A DABT is reported[1] on an android based system when resume from hiberate.This happens because swsusp_arch_suspend_exit() is marked with SYM_CODE_*()and does not have a CFI hash, but swsusp_arch_resume() will attempt toverify the CFI hash when calling a copy of swsusp_arch_suspend_exit().Given that there's an existing requirement that the entrypoint toswsusp_arch_suspend_exit() is the first byte of the .hibernate_exit.textsection, we cannot fix this by marking swsusp_arch_suspend_exit() withSYM_FUNC_*(). The simplest fix for now is to disable the CFI check inswsusp_arch_resume().Mark swsusp_arch_resume() as __nocfi to disable the CFI check.[1][ 22.991934][ T1] Unable to handle kernel paging request at virtual address 0000000109170ffc[ 22.991934][ T1] Mem abort info:[ 22.991934][ T1] ESR = 0x0000000096000007[ 22.991934][ T1] EC = 0x25: DABT (current EL), IL = 32 bits[ 22.991934][ T1] SET = 0, FnV = 0[ 22.991934][ T1] EA = 0, S1PTW = 0[ 22.991934][ T1] FSC = 0x07: level 3 translation fault[ 22.991934][ T1] Data abort info:[ 22.991934][ T1] ISV = 0, ISS = 0x00000007, ISS2 = 0x00000000[ 22.991934][ T1] CM = 0, WnR = 0, TnD = 0, TagAccess = 0[ 22.991934][ T1] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0[ 22.991934][ T1] [0000000109170ffc] user address but active_mm is swapper[ 22.991934][ T1] Internal error: Oops: 0000000096000007 [#1] PREEMPT SMP[ 22.991934][ T1] Dumping ftrace buffer:[ 22.991934][ T1] (ftrace buffer empty)[ 22.991934][ T1] Modules linked in:[ 22.991934][ T1] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 6.6.98-android15-8-g0b1d2aee7fc3-dirty-4k #1 688c7060a825a3ac418fe53881730b355915a419[ 22.991934][ T1] Hardware name: Unisoc UMS9360-base Board (DT)[ 22.991934][ T1] pstate: 804000c5 (Nzcv daIF +PAN -UAO -TCO -DIT -SSBS BTYPE=--)[ 22.991934][ T1] pc : swsusp_arch_resume+0x2ac/0x344[ 22.991934][ T1] lr : swsusp_arch_resume+0x294/0x344[ 22.991934][ T1] sp : ffffffc08006b960[ 22.991934][ T1] x29: ffffffc08006b9c0 x28: 0000000000000000 x27: 0000000000000000[ 22.991934][ T1] x26: 0000000000000000 x25: 0000000000000000 x24: 0000000000000820[ 22.991934][ T1] x23: ffffffd0817e3000 x22: ffffffd0817e3000 x21: 0000000000000000[ 22.991934][ T1] x20: ffffff8089171000 x19: ffffffd08252c8c8 x18: ffffffc080061058[ 22.991934][ T1] x17: 00000000529c6ef0 x16: 00000000529c6ef0 x15: 0000000000000004[ 22.991934][ T1] x14: ffffff8178c88000 x13: 0000000000000006 x12: 0000000000000000[ 22.991934][ T1] x11: 0000000000000015 x10: 0000000000000001 x9 : ffffffd082533000[ 22.991934][ T1] x8 : 0000000109171000 x7 : 205b5d3433393139 x6 : 392e32322020205b[ 22.991934][ T1] x5 : 000000010916f000 x4 : 000000008164b000 x3 : ffffff808a4e0530[ 22.991934][ T1] x2 : ffffffd08058e784 x1 : 0000000082326000 x0 : 000000010a283000[ 22.991934][ T1] Call trace:[ 22.991934][ T1] swsusp_arch_resume+0x2ac/0x344[ 22.991934][ T1] hibernation_restore+0x158/0x18c[ 22.991934][ T1] load_image_and_restore+0xb0/0xec[ 22.991934][ T1] software_resume+0xf4/0x19c[ 22.991934][ T1] software_resume_initcall+0x34/0x78[ 22.991934][ T1] do_one_initcall+0xe8/0x370[ 22.991934][ T1] do_initcall_level+0xc8/0x19c[ 22.991934][ T1] do_initcalls+0x70/0xc0[ 22.991934][ T1] do_basic_setup+0x1c/0x28[ 22.991934][ T1] kernel_init_freeable+0xe0/0x148[ 22.991934][ T1] kernel_init+0x20/0x1a8[ 22.991934][ T1] ret_from_fork+0x10/0x20[ 22.991934][ T1] Code: a9400a61 f94013e0 f9438923 f9400a64 (b85fc110)[catalin.marinas@arm.com: commit log updated by Mark Rutland]

Description: In the Linux kernel, the following vulnerability has been resolved:dpll: Prevent duplicate registrationsModify the internal registration helpers dpll_xa_ref_{dpll,pin}_add()to reject duplicate registration attempts.Previously, if a caller attempted to register the same pin multipletimes (with the same ops, priv, and cookie) on the same device, the coresilently increments the reference count and return success. This behavioris incorrect because if the caller makes these duplicate registrationsthen for the first one dpll_pin_registration is allocated and for othersthe associated dpll_pin_ref.refcount is incremented. During the firstunregistration the associated dpll_pin_registration is freed and forothers WARN is fired.Fix this by updating the logic to return `-EEXIST` if a matchingregistration is found to enforce a strict "register once" policy.

Description: In the Linux kernel, the following vulnerability has been resolved:libceph: reset sparse-read state in osd_fault()When a fault occurs, the connection is abandoned, reestablished, and anypending operations are retried. The OSD client tracks the progress of asparse-read reply using a separate state machine, largely independent ofthe messenger's state.If a connection is lost mid-payload or the sparse-read state machinereturns an error, the sparse-read state is not reset. The OSD clientwill then interpret the beginning of a new reply as the continuation ofthe old one. If this makes the sparse-read machinery enter a failurestate, it may never recover, producing loops like: libceph: [0] got 0 extents libceph: data len 142248331 != extent len 0 libceph: osd0 (1)...:6801 socket error on read libceph: data len 142248331 != extent len 0 libceph: osd0 (1)...:6801 socket error on readTherefore, reset the sparse-read state in osd_fault(), ensuring retriesstart from a clean state.

Each bit represents the context that the event isin (normal, softirq, interrupt and NMI).Have the stack trace code use the interrupt context to protect againstrecursion.Note, the bug showed an issue in both the RCU code as well as the tracingstacktrace code. This only handles the tracing stack trace side of thebug. The RCU fix will be handled separately.

CVE-2026-23140 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf, test_run: Subtract size of xdp_frame from allowed metadata sizeThe xdp_frame structure takes up part of the XDP frame headroom,limiting the size of the metadata. However, in bpf_test_run, we don'ttake this into account, which makes it possible for userspace to supplya metadata size that is too large (taking up the entire headroom).If userspace supplies such a large metadata size in live packet mode,the xdp_update_frame_from_buff() call in xdp_test_run_init_page() callwill fail, after which packet transmission proceeds with anuninitialised frame structure, leading to the usual Bad Stuff.The commit in the Fixes tag fixed a related bug where the second checkin xdp_update_frame_from_buff() could fail, but did not add anyadditional constraints on the metadata size. Complete the fix by addingan additional check on the metadata size. Reorder the checks slightly tomake the logic clearer and add a comment.

CVE-2026-23154 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix segmentation of forwarding fraglist GROThis patch enhances GSO segment handling by properly checkingthe SKB_GSO_DODGY flag for frag_list GSO packets, addressinglow throughput issues observed when a station accesses IPv4servers via hotspots with an IPv6-only upstream interface.Specifically, it fixes a bug in GSO segmentation when forwardingGRO packets containing a frag_list. The function skb_segment_listcannot correctly process GRO skbs that have been converted by XLAT,since XLAT only translates the header of the head skb. Consequently,skbs in the frag_list may remain untranslated, resulting in protocolinconsistencies and reduced throughput.To address this, the patch explicitly sets the SKB_GSO_DODGY flagfor GSO packets in XLAT's IPv4/IPv6 protocol translation helpers(bpf_skb_proto_4_to_6 and bpf_skb_proto_6_to_4). This marks GSOpackets as potentially modified after protocol translation. As aresult, GSO segmentation will avoid using skb_segment_list andinstead falls back to skb_segment for packets with the SKB_GSO_DODGYflag. This ensures that only safe and fully translated frag_listpackets are processed by skb_segment_list, resolving protocolinconsistencies and improving throughput when forwarding GRO packetsconverted by XLAT.

CVE-2026-23157 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: do not strictly require dirty metadata threshold for metadata writepages[BUG]There is an internal report that over 1000 processes arewaiting at the io_schedule_timeout() of balance_dirty_pages(), causinga system hang and trigger a kernel coredump.The kernel is v6.4 kernel based, but the root problem still applies toany upstream kernel before v6.18.[CAUSE]From Jan Kara for his wisdom on the dirty page balance behavior first. This cgroup dirty limit was what was actually playing the role here because the cgroup had only a small amount of memory and so the dirty limit for it was something like 16MB. Dirty throttling is responsible for enforcing that nobody can dirty (significantly) more dirty memory than there's dirty limit. Thus when a task is dirtying pages it periodically enters into balance_dirty_pages() and we let it sleep there to slow down the dirtying. When the system is over dirty limit already (either globally or within a cgroup of the running task), we will not let the task exit from balance_dirty_pages() until the number of dirty pages drops below the limit. So in this particular case, as I already mentioned, there was a cgroup with relatively small amount of memory and as a result with dirty limit set at 16MB. A task from that cgroup has dirtied about 28MB worth of pages in btrfs btree inode and these were practically the only dirty pages in that cgroup.So that means the only way to reduce the dirty pages of that cgroup isto writeback the dirty pages of btrfs btree inode, and only after thatthose processes can exit balance_dirty_pages().Now back to the btrfs part, btree_writepages() is responsible forwriting back dirty btree inode pages.The problem here is, there is a btrfs internal threshold that if thebtree inode's dirty bytes are below the 32M threshold, it will notdo any writeback.This behavior is to batch as much metadata as possible so we won't writeback those tree blocks and then later re-COW them again for anothermodification.This internal 32MiB is higher than the existing dirty page size (28MiB),meaning no writeback will happen, causing a deadlock between btrfs andcgroup:- Btrfs doesn't want to write back btree inode until more dirty pages- Cgroup/MM doesn't want more dirty pages for btrfs btree inode Thus any process touching that btree inode is put into sleep until the number of dirty pages is reduced.Thanks Jan Kara a lot for the analysis of the root cause.[ENHANCEMENT]Since kernel commit b55102826d7d ("btrfs: set AS_KERNEL_FILE on thebtree_inode"), btrfs btree inode pages will only be charged to the rootcgroup which should have a much larger limit than btrfs' 32MiBthreshold.So it should not affect newer kernels.But for all current LTS kernels, they are all affected by this problem,and backporting the whole AS_KERNEL_FILE may not be a good idea.Even for newer kernels I still think it's a good idea to getrid of the internal threshold at btree_writepages(), since for most casescgroup/MM has a better view of full system memory usage than btrfs' fixedthreshold.For internal callers using btrfs_btree_balance_dirty() since thatfunction is already doing internal threshold check, we don't need tobother them.But for external callers of btree_writepages(), just respect theirrequests and write back whatever they want, ignoring the internalbtrfs threshold to avoid such deadlock on btree inode dirty pagebalancing.

CVE-2026-23164 Severity: Moderate CVSS3 score: 5.5

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-2026-23167 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:nfc: nci: Fix race between rfkill and nci_unregister_device().syzbot reported the splat below [0] without a repro.It indicates that struct nci_dev.cmd_wq had been destroyed beforenci_close_device() was called via rfkill.nci_dev.cmd_wq is only destroyed in nci_unregister_device(), which(I think) was called from virtual_ncidev_close() when syzbot close()dan fd of virtual_ncidev.The problem is that nci_unregister_device() destroys nci_dev.cmd_wqfirst and then calls nfc_unregister_device(), which removes thedevice from rfkill by rfkill_unregister().So, the device is still visible via rfkill even after nci_dev.cmd_wqis destroyed.Let's unregister the device from rfkill first in nci_unregister_device().Note that we cannot call nfc_unregister_device() beforenci_close_device() because 1) nfc_unregister_device() calls device_del() which frees all memory allocated by devm_kzalloc() and linked to ndev->conn_info_list 2) nci_rx_work() could try to queue nci_conn_info to ndev->conn_info_list which could be leakedThus, nfc_unregister_device() is split into two functions so wecan remove rfkill interfaces only before nci_close_device().[0]:DEBUG_LOCKS_WARN_ON(1)WARNING: kernel/locking/lockdep.c:238 at hlock_class kernel/locking/lockdep.c:238 [inline], CPU#0: syz.0.8675/6349WARNING: kernel/locking/lockdep.c:238 at check_wait_context kernel/locking/lockdep.c:4854 [inline], CPU#0: syz.0.8675/6349WARNING: kernel/locking/lockdep.c:238 at __lock_acquire+0x39d/0x2cf0 kernel/locking/lockdep.c:5187, CPU#0: syz.0.8675/6349Modules linked in:CPU: 0 UID: 0 PID: 6349 Comm: syz.0.8675 Not tainted syzkaller #0 PREEMPT(full)Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/13/2026RIP: 0010:hlock_class kernel/locking/lockdep.c:238 [inline]RIP: 0010:check_wait_context kernel/locking/lockdep.c:4854 [inline]RIP: 0010:__lock_acquire+0x3a4/0x2cf0 kernel/locking/lockdep.c:5187Code: 18 00 4c 8b 74 24 08 75 27 90 e8 17 f2 fc 02 85 c0 74 1c 83 3d 50 e0 4e 0e 00 75 13 48 8d 3d 43 f7 51 0e 48 c7 c6 8b 3a de 8d <67> 48 0f b9 3a 90 31 c0 0f b6 98 c4 00 00 00 41 8b 45 20 25 ff 1fRSP: 0018:ffffc9000c767680 EFLAGS: 00010046RAX: 0000000000000001 RBX: 0000000000040000 RCX: 0000000000080000RDX: ffffc90013080000 RSI: ffffffff8dde3a8b RDI: ffffffff8ff24ca0RBP: 0000000000000003 R08: ffffffff8fef35a3 R09: 1ffffffff1fde6b4R10: dffffc0000000000 R11: fffffbfff1fde6b5 R12: 00000000000012a2R13: ffff888030338ba8 R14: ffff888030338000 R15: ffff888030338b30FS: 00007fa5995f66c0(0000) GS:ffff8881256f8000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007f7e72f842d0 CR3: 00000000485a0000 CR4: 00000000003526f0Call Trace: lock_acquire+0x106/0x330 kernel/locking/lockdep.c:5868 touch_wq_lockdep_map+0xcb/0x180 kernel/workqueue.c:3940 __flush_workqueue+0x14b/0x14f0 kernel/workqueue.c:3982 nci_close_device+0x302/0x630 net/nfc/nci/core.c:567 nci_dev_down+0x3b/0x50 net/nfc/nci/core.c:639 nfc_dev_down+0x152/0x290 net/nfc/core.c:161 nfc_rfkill_set_block+0x2d/0x100 net/nfc/core.c:179 rfkill_set_block+0x1d2/0x440 net/rfkill/core.c:346 rfkill_fop_write+0x461/0x5a0 net/rfkill/core.c:1301 vfs_write+0x29a/0xb90 fs/read_write.c:684 ksys_write+0x150/0x270 fs/read_write.c:738 do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline] do_syscall_64+0xe2/0xf80 arch/x86/entry/syscall_64.c:94 entry_SYSCALL_64_after_hwframe+0x77/0x7fRIP: 0033:0x7fa59b39acb9Code: ff c3 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 e8 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007fa5995f6028 EFLAGS: 00000246 ORIG_RAX: 0000000000000001RAX: ffffffffffffffda RBX: 00007fa59b615fa0 RCX: 00007fa59b39acb9RDX: 0000000000000008 RSI: 0000200000000080 RDI: 0000000000000007RBP: 00007fa59b408bf7 R08: ---truncated---

CVE-2026-23172 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: wwan: t7xx: fix potential skb->frags overflow in RX pathWhen receiving data in the DPMAIF RX path,the t7xx_dpmaif_set_frag_to_skb() function addspage fragments to an skb without checking if the number offragments has exceeded MAX_SKB_FRAGS. This could lead to a buffer overflowin skb_shinfo(skb)->frags[] array, corrupting adjacent memory andpotentially causing kernel crashes or other undefined behavior.This issue was identified through static code analysis by comparing with asimilar vulnerability fixed in the mt76 driver commit b102f0c522cf ("mt76:fix array overflow on receiving too many fragments for a packet").The vulnerability could be triggered if the modem firmware sends packetswith excessive fragments. While under normal protocol conditions (MTU 3080bytes, BAT buffer 3584 bytes),a single packet should not require additionalfragments, the kernel should not blindly trust firmware behavior.Malicious, buggy, or compromised firmware could potentially craft packetswith more fragments than the kernel expects.Fix this by adding a bounds check before calling skb_add_rx_frag() toensure nr_frags does not exceed MAX_SKB_FRAGS.The check must be performed before unmapping to avoid a page leakand double DMA unmap during device teardown.

Description: In the Linux kernel, the following vulnerability has been resolved:ceph: fix oops due to invalid pointer for kfree() in parse_longname()This fixes a kernel oops when reading ceph snapshot directories (.snap),for example by simply running `ls /mnt/my_ceph/.snap`.The variable str is guarded by __free(kfree), but advanced by one forskipping the initial '_' in snapshot names. Thus, kfree() is calledwith an invalid pointer. This patch removes the need for advancing thepointer so kfree() is called with correct memory pointer.Steps to reproduce:1. Create snapshots on a cephfs volume (I've 63 snaps in my testcase)2. Add cephfs mount to fstab$ echo "samba-fileserver@.files=/volumes/datapool/stuff/3461082b-ecc9-4e82-8549-3fd2590d3fb6 /mnt/test/stuff ceph acl,noatime,_netdev 0 0" >> /etc/fstab3. Reboot the system$ systemctl reboot4. Check if it's really mounted$ mount | grep stuff5. List snapshots (expected 63 snapshots on my system)$ ls /mnt/test/stuff/.snapNow ls hangs forever and the kernel log shows the oops.

After the vmware hypercall it now contains0x40003e54, and we get a page fault as a result when it is dereferenced.The proper fix would be in QEMU, but this works around the issue in thekernel to keep old setups working, when old kernels had not happened tokeep any state in %rdi over the hypercall.In theory this same issue exists for all the hypercalls in the vmmousedriver; in practice it has only been seen with vmware_hypercall3() andvmware_hypercall4(). For now, just mark RDI/RSI as clobbered for thosetwo calls. This should have a minimal effect on code generation overallas it should be rare for the compiler to want to make RDI/RSI liveacross hypercalls.

The upperlimit is PR_KEYS_MAX (64K).A malicious or buggy userspace can pass a large num_keys value thatresults in a 4MB allocation attempt at most, causing a warning inthe page allocator when the order exceeds MAX_PAGE_ORDER.To fix this, use kvzalloc() instead of kzalloc().This bug has the same reasoning and fix with the patch below:https://lore.kernel.org/linux-block/20251212013510.3576091-1-kartikey406@gmail.com/Warning log:WARNING: mm/page_alloc.c:5216 at __alloc_frozen_pages_noprof+0x5aa/0x2300 mm/page_alloc.c:5216, CPU#1: syz-executor117/272Modules linked in:CPU: 1 UID: 0 PID: 272 Comm: syz-executor117 Not tainted 6.19.0 #1 PREEMPT(voluntary)Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014RIP: 0010:__alloc_frozen_pages_noprof+0x5aa/0x2300 mm/page_alloc.c:5216Code: ff 83 bd a8 fe ff ff 0a 0f 86 69 fb ff ff 0f b6 1d f9 f9 c4 04 80 fb 01 0f 87 3b 76 30 ff 83 e3 01 75 09 c6 05 e4 f9 c4 04 01 <0f> 0b 48 c7 85 70 fe ff ff 00 00 00 00 e9 8f fd ff ff 31 c0 e9 0dRSP: 0018:ffffc90000fcf450 EFLAGS: 00010246RAX: 0000000000000000 RBX: 0000000000000000 RCX: 1ffff920001f9ea0RDX: 0000000000000000 RSI: 000000000000000b RDI: 0000000000040dc0RBP: ffffc90000fcf648 R08: ffff88800b6c3380 R09: 0000000000000001R10: ffffc90000fcf840 R11: ffff88807ffad280 R12: 0000000000000000R13: 0000000000040dc0 R14: 0000000000000001 R15: ffffc90000fcf620FS: 0000555565db33c0(0000) GS:ffff8880be26c000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 000000002000000c CR3: 0000000003b72000 CR4: 00000000000006f0Call Trace: alloc_pages_mpol+0x236/0x4d0 mm/mempolicy.c:2486 alloc_frozen_pages_noprof+0x149/0x180 mm/mempolicy.c:2557 ___kmalloc_large_node+0x10c/0x140 mm/slub.c:5598 __kmalloc_large_node_noprof+0x25/0xc0 mm/slub.c:5629 __do_kmalloc_node mm/slub.c:5645 [inline] __kmalloc_noprof+0x483/0x6f0 mm/slub.c:5669 kmalloc_noprof include/linux/slab.h:961 [inline] kzalloc_noprof include/linux/slab.h:1094 [inline] nvme_pr_read_keys+0x8f/0x4c0 drivers/nvme/host/pr.c:245 blkdev_pr_read_keys block/ioctl.c:456 [inline] blkdev_common_ioctl+0x1b71/0x29b0 block/ioctl.c:730 blkdev_ioctl+0x299/0x700 block/ioctl.c:786 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:597 [inline] __se_sys_ioctl fs/ioctl.c:583 [inline] __x64_sys_ioctl+0x1bf/0x220 fs/ioctl.c:583 x64_sys_call+0x1280/0x21b0 mnt/fuzznvme_1/fuzznvme/linux-build/v6.19/./arch/x86/include/generated/asm/syscalls_64.h:17 do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline] do_syscall_64+0x71/0x330 arch/x86/entry/syscall_64.c:94 entry_SYSCALL_64_after_hwframe+0x76/0x7eRIP: 0033:0x7fb893d3108dCode: 28 c3 e8 46 1e 00 00 66 0f 1f 44 00 00 f3 0f 1e fa 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b8 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007ffff61f2f38 EFLAGS: 00000246 ORIG_RAX: 0000000000000010RAX: ffffffffffffffda RBX: 00007ffff61f3138 RCX: 00007fb893d3108dRDX: 0000000020000040 RSI: 00000000c01070ce RDI: 0000000000000003RBP: 0000000000000001 R08: 0000000000000000 R09: 00007ffff61f3138R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000001R13: 00007ffff61f3128 R14: 00007fb893dae530 R15: 0000000000000001

CVE-2026-23270 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: Only allow act_ct to bind to clsact/ingress qdiscs and shared blocksAs Paolo said earlier [1]:"Since the blamed commit below, classify can return TC_ACT_CONSUMED whilethe current skb being held by the defragmentation engine. As reported byGangMin Kim, if such packet is that may cause a UaF when the defrag enginelater on tries to tuch again such packet."act_ct was never meant to be used in the egress path, however some usersare attaching it to egress today [2]. Attempting to reach a middleground, we noticed that, while most qdiscs are not handlingTC_ACT_CONSUMED, clsact/ingress qdiscs are. With that in mind, weaddress the issue by only allowing act_ct to bind to clsact/ingressqdiscs and shared blocks. That way it's still possible to attach act_ct toegress (albeit only with clsact).[1] https://lore.kernel.org/netdev/674b8cbfc385c6f37fb29a1de08d8fe5c2b0fbee.1771321118.git.pabeni@redhat.com/[2] https://lore.kernel.org/netdev/cc6bfb4a-4a2b-42d8-b9ce-7ef6644fb22b@ovn.org/

CVE-2026-23343 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:xdp: produce a warning when calculated tailroom is negativeMany ethernet drivers report xdp Rx queue frag size as being the same asDMA write size. However, the only user of this field, namelybpf_xdp_frags_increase_tail(), clearly expects a truesize.Such difference leads to unspecific memory corruption issues under certaincircumstances, e.g. in ixgbevf maximum DMA write size is 3 KB, so whenrunning xskxceiver's XDP_ADJUST_TAIL_GROW_MULTI_BUFF, 6K packet fully usesall DMA-writable space in 2 buffers. This would be fine, if onlyrxq->frag_size was properly set to 4K, but value of 3K results in anegative tailroom, because there is a non-zero page offset.We are supposed to return -EINVAL and be done with it in such case, but dueto tailroom being stored as an unsigned int, it is reported to be somewherenear UINT_MAX, resulting in a tail being grown, even if the requestedoffset is too much (it is around 2K in the abovementioned test). This laterleads to all kinds of unspecific calltraces.[ 7340.337579] xskxceiver[1440]: segfault at 1da718 ip 00007f4161aeac9d sp 00007f41615a6a00 error 6[ 7340.338040] xskxceiver[1441]: segfault at 7f410000000b ip 00000000004042b5 sp 00007f415bffecf0 error 4[ 7340.338179] in libc.so.6[61c9d,7f4161aaf000+160000][ 7340.339230] in xskxceiver[42b5,400000+69000][ 7340.340300] likely on CPU 6 (core 0, socket 6)[ 7340.340302] Code: ff ff 01 e9 f4 fe ff ff 0f 1f 44 00 00 4c 39 f0 74 73 31 c0 ba 01 00 00 00 f0 0f b1 17 0f 85 ba 00 00 00 49 8b 87 88 00 00 00 <4c> 89 70 08 eb cc 0f 1f 44 00 00 48 8d bd f0 fe ff ff 89 85 ec fe[ 7340.340888] likely on CPU 3 (core 0, socket 3)[ 7340.345088] Code: 00 00 00 ba 00 00 00 00 be 00 00 00 00 89 c7 e8 31 ca ff ff 89 45 ec 8b 45 ec 85 c0 78 07 b8 00 00 00 00 eb 46 e8 0b c8 ff ff <8b> 00 83 f8 69 74 24 e8 ff c7 ff ff 8b 00 83 f8 0b 74 18 e8 f3 c7[ 7340.404334] Oops: general protection fault, probably for non-canonical address 0x6d255010bdffc: 0000 [#1] SMP NOPTI[ 7340.405972] CPU: 7 UID: 0 PID: 1439 Comm: xskxceiver Not tainted 6.19.0-rc1+ #21 PREEMPT(lazy)[ 7340.408006] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.17.0-5.fc42 04/01/2014[ 7340.409716] RIP: 0010:lookup_swap_cgroup_id+0x44/0x80[ 7340.410455] Code: 83 f8 1c 73 39 48 ba ff ff ff ff ff ff ff 03 48 8b 04 c5 20 55 fa bd 48 21 d1 48 89 ca 83 e1 01 48 d1 ea c1 e1 04 48 8d 04 90 <8b> 00 48 83 c4 10 d3 e8 c3 cc cc cc cc 31 c0 e9 98 b7 dd 00 48 89[ 7340.412787] RSP: 0018:ffffcc5c04f7f6d0 EFLAGS: 00010202[ 7340.413494] RAX: 0006d255010bdffc RBX: ffff891f477895a8 RCX: 0000000000000010[ 7340.414431] RDX: 0001c17e3fffffff RSI: 00fa070000000000 RDI: 000382fc7fffffff[ 7340.415354] RBP: 00fa070000000000 R08: ffffcc5c04f7f8f8 R09: ffffcc5c04f7f7d0[ 7340.416283] R10: ffff891f4c1a7000 R11: ffffcc5c04f7f9c8 R12: ffffcc5c04f7f7d0[ 7340.417218] R13: 03ffffffffffffff R14: 00fa06fffffffe00 R15: ffff891f47789500[ 7340.418229] FS: 0000000000000000(0000) GS:ffff891ffdfaa000(0000) knlGS:0000000000000000[ 7340.419489] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 7340.420286] CR2: 00007f415bfffd58 CR3: 0000000103f03002 CR4: 0000000000772ef0[ 7340.421237] PKRU: 55555554[ 7340.421623] Call Trace:[ 7340.421987] [ 7340.422309] ? softleaf_from_pte+0x77/0xa0[ 7340.422855] swap_pte_batch+0xa7/0x290[ 7340.423363] zap_nonpresent_ptes.constprop.0.isra.0+0xd1/0x270[ 7340.424102] zap_pte_range+0x281/0x580[ 7340.424607] zap_pmd_range.isra.0+0xc9/0x240[ 7340.425177] unmap_page_range+0x24d/0x420[ 7340.425714] unmap_vmas+0xa1/0x180[ 7340.426185] exit_mmap+0xe1/0x3b0[ 7340.426644] __mmput+0x41/0x150[ 7340.427098] exit_mm+0xb1/0x110[ 7340.427539] do_exit+0x1b2/0x460[ 7340.427992] do_group_exit+0x2d/0xc0[ 7340.428477] get_signal+0x79d/0x7e0[ 7340.428957] arch_do_signal_or_restart+0x34/0x100[ 7340.429571] exit_to_user_mode_loop+0x8e/0x4c0[ 7340.430159] do_syscall_64+0x188/---truncated---

On arm64, the 'pgprot_t' contains all of the non-addressbits from the pte, including the permission controls, and so we end upreturning a new user mapping from ioremap_prot() which faults whenaccessed from the kernel on systems with PAN: | Unable to handle kernel read from unreadable memory at virtual address ffff80008ea89000 | ... | Call trace: | __memcpy_fromio+0x80/0xf8 | generic_access_phys+0x20c/0x2b8 | __access_remote_vm+0x46c/0x5b8 | access_remote_vm+0x18/0x30 | environ_read+0x238/0x3e8 | vfs_read+0xe4/0x2b0 | ksys_read+0xcc/0x178 | __arm64_sys_read+0x4c/0x68Extract only the memory type from the user 'pgprot_t' in ioremap_prot()and assert that we're being passed a user mapping, to protect us againstany changes in future that may require additional handling.

CVE-2026-23348 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:cxl: Fix race of nvdimm_bus object when creating nvdimm objectsFound issue during running of cxl-translate.sh unit test. Adding a 3ssleep right before the test seems to make the issue reproduce fairlyconsistently. The cxl_translate module has dependency on cxl_acpi andcauses orphaned nvdimm objects to reprobe after cxl_acpi is removed.The nvdimm_bus object is registered by the cxl_nvb object whencxl_acpi_probe() is called. With the nvdimm_bus object missing,__nd_device_register() will trigger NULL pointer dereference whenaccessing the dev->parent that points to &nvdimm_bus->dev.[ 192.884510] BUG: kernel NULL pointer dereference, address: 000000000000006c[ 192.895383] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS edk2-20250812-19.fc42 08/12/2025[ 192.897721] Workqueue: cxl_port cxl_bus_rescan_queue [cxl_core][ 192.899459] RIP: 0010:kobject_get+0xc/0x90[ 192.924871] Call Trace:[ 192.925959] [ 192.926976] ? pm_runtime_init+0xb9/0xe0[ 192.929712] __nd_device_register.part.0+0x4d/0xc0 [libnvdimm][ 192.933314] __nvdimm_create+0x206/0x290 [libnvdimm][ 192.936662] cxl_nvdimm_probe+0x119/0x1d0 [cxl_pmem][ 192.940245] cxl_bus_probe+0x1a/0x60 [cxl_core][ 192.943349] really_probe+0xde/0x380This patch also relies on the previous change wheredevm_cxl_add_nvdimm_bridge() is called from drivers/cxl/pmem.c insteadof drivers/cxl/core.c to ensure the dependency of cxl_acpi on cxl_pmem.1. Set probe_type of cxl_nvb to PROBE_FORCE_SYNCHRONOUS to ensure the driver is probed synchronously when add_device() is called.2.

Set cxl_nvdimm flag to CXL_NVD_F_INVALIDATED so cxl_nvdimm_probe() will exit with -EBUSY.The removal of cxl_nvdimm devices should prevent any orphaned devicesfrom probing once the nvdimm_bus is gone.[ dj: Fixed 0-day reported kdoc issue. ][ dj: Fix cxl_nvb reference leak on error.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nft_set_pipapo: split gc into unlink and reclaim phaseYiming Qian reports Use-after-free in the pipapo set type: Under a large number of expired elements, commit-time GC can run for a very long time in a non-preemptible context, triggering soft lockup warnings and RCU stall reports (local denial of service).We must split GC in an unlink and a reclaim phase.We cannot queue elements for freeing until pointers have been swapped.Expired elements are still exposed to both the packet path and userspacedumpers via the live copy of the data structure.call_rcu() does not protect us: dump operations or element lookups startingafter call_rcu has fired can still observe the free'd element, unless thecommit phase has made enough progress to swap the clone and live pointersbefore any new reader has picked up the old version.This a similar approach as done recently for the rbtree backend in commit35f83a75529a ("netfilter: nft_set_rbtree: don't gc elements on insert").

CVE-2026-23352 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:x86/efi: defer freeing of boot services memoryefi_free_boot_services() frees memory occupied by EFI_BOOT_SERVICES_CODEand EFI_BOOT_SERVICES_DATA using memblock_free_late().There are two issue with that: memblock_free_late() should be used formemory allocated with memblock_alloc() while the memory reserved withmemblock_reserve() should be freed with free_reserved_area().More acutely, with CONFIG_DEFERRED_STRUCT_PAGE_INIT=yefi_free_boot_services() is called before deferred initialization of thememory map is complete.Benjamin Herrenschmidt reports that this causes a leak of ~140MB ofRAM on EC2 t3a.nano instances which only have 512MB or RAM.If the freed memory resides in the areas that memory map for them isstill uninitialized, they won't be actually freed becausememblock_free_late() calls memblock_free_pages() and the latter skipsuninitialized pages.Using free_reserved_area() at this point is also problematic because__free_page() accesses the buddy of the freed page and that again mightend up in uninitialized part of the memory map.Delaying the entire efi_free_boot_services() could be problematicbecause in addition to freeing boot services memory it updatesefi.memmap without any synchronization and that's undesirable late inboot when there is concurrency.More robust approach is to only defer freeing of the EFI boot servicesmemory.Split efi_free_boot_services() in two. First efi_unmap_boot_services()collects ranges that should be freed into an array thenefi_free_boot_services() later frees them after deferred init is complete.

A classical AB-BA deadlock.phy_led_triggers_registers() does not require the RTNL, it does notmake any calls into the network stack which require protection. Thereis also no requirement the PHY has been attached to a MAC, thetriggers only make use of phydev state. This allows the call tophy_led_triggers_registers() to be placed elsewhere. PHY probe() andrelease() don't hold RTNL, so solving the AB-BA deadlock.

It clearly expects whole buff size insteadof DMA write size. Different assumptions in ice driver configuration leadto negative tailroom.This allows to trigger kernel panic, when usingXDP_ADJUST_TAIL_GROW_MULTI_BUFF xskxceiver test and changing packet size to6912 and the requested offset to a huge value, e.g.XSK_UMEM__MAX_FRAME_SIZE * 100.Due to other quirks of the ZC configuration in ice, panic is not observedin ZC mode, but tailroom growing still fails when it should not.Use fill queue buffer truesize instead of DMA write size in XDP RxQ info.Fix ZC mode too by using the new helper.

Using unsignedint, the same integer size as the individual DRR quanta, can overflow andeven cause division by zero, like it happened in the following splat: Oops: divide error: 0000 [#1] SMP PTI CPU: 13 UID: 0 PID: 487 Comm: tc Tainted: G E 6.19.0-virtme #45 PREEMPT(full) Tainted: [E]=UNSIGNED_MODULE Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 RIP: 0010:ets_offload_change+0x11f/0x290 [sch_ets] Code: e4 45 31 ff eb 03 41 89 c7 41 89 cb 89 ce 83 f9 0f 0f 87 b7 00 00 00 45 8b 08 31 c0 45 01 cc 45 85 c9 74 09 41 6b c4 64 31 d2 <41> f7 f2 89 c2 44 29 fa 45 89 df 41 83 fb 0f 0f 87 c7 00 00 00 44 RSP: 0018:ffffd0a180d77588 EFLAGS: 00010246 RAX: 00000000ffffff38 RBX: ffff8d3d482ca000 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffffd0a180d77660 RBP: ffffd0a180d77690 R08: ffff8d3d482ca2d8 R09: 00000000fffffffe R10: 0000000000000000 R11: 0000000000000000 R12: 00000000fffffffe R13: ffff8d3d472f2000 R14: 0000000000000003 R15: 0000000000000000 FS: 00007f440b6c2740(0000) GS:ffff8d3dc9803000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000000003cdd2000 CR3: 0000000007b58002 CR4: 0000000000172ef0 Call Trace: ets_qdisc_change+0x870/0xf40 [sch_ets] qdisc_create+0x12b/0x540 tc_modify_qdisc+0x6d7/0xbd0 rtnetlink_rcv_msg+0x168/0x6b0 netlink_rcv_skb+0x5c/0x110 netlink_unicast+0x1d6/0x2b0 netlink_sendmsg+0x22e/0x470 ____sys_sendmsg+0x38a/0x3c0 ___sys_sendmsg+0x99/0xe0 __sys_sendmsg+0x8a/0xf0 do_syscall_64+0x111/0xf80 entry_SYSCALL_64_after_hwframe+0x77/0x7f RIP: 0033:0x7f440b81c77e Code: 4d 89 d8 e8 d4 bc 00 00 4c 8b 5d f8 41 8b 93 08 03 00 00 59 5e 48 83 f8 fc 74 11 c9 c3 0f 1f 80 00 00 00 00 48 8b 45 10 0f 05 c3 83 e2 39 83 fa 08 75 e7 e8 13 ff ff ff 0f 1f 00 f3 0f 1e fa RSP: 002b:00007fff951e4c10 EFLAGS: 00000202 ORIG_RAX: 000000000000002e RAX: ffffffffffffffda RBX: 0000000000481820 RCX: 00007f440b81c77e RDX: 0000000000000000 RSI: 00007fff951e4cd0 RDI: 0000000000000003 RBP: 00007fff951e4c20 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000202 R12: 00007fff951f4fa8 R13: 00000000699ddede R14: 00007f440bb01000 R15: 0000000000486980 Modules linked in: sch_ets(E) netdevsim(E) ---[ end trace 0000000000000000 ]--- RIP: 0010:ets_offload_change+0x11f/0x290 [sch_ets] Code: e4 45 31 ff eb 03 41 89 c7 41 89 cb 89 ce 83 f9 0f 0f 87 b7 00 00 00 45 8b 08 31 c0 45 01 cc 45 85 c9 74 09 41 6b c4 64 31 d2 <41> f7 f2 89 c2 44 29 fa 45 89 df 41 83 fb 0f 0f 87 c7 00 00 00 44 RSP: 0018:ffffd0a180d77588 EFLAGS: 00010246 RAX: 00000000ffffff38 RBX: ffff8d3d482ca000 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffffd0a180d77660 RBP: ffffd0a180d77690 R08: ffff8d3d482ca2d8 R09: 00000000fffffffe R10: 0000000000000000 R11: 0000000000000000 R12: 00000000fffffffe R13: ffff8d3d472f2000 R14: 0000000000000003 R15: 0000000000000000 FS: 00007f440b6c2740(0000) GS:ffff8d3dc9803000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000000003cdd2000 CR3: 0000000007b58002 CR4: 0000000000172ef0 Kernel panic - not syncing: Fatal exception Kernel Offset: 0x30000000 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff) ---[ end Kernel panic - not syncing: Fatal exception ]---Fix this using 64-bit integers for 'q_sum' and 'q_psum'.

Description: In the Linux kernel, the following vulnerability has been resolved:net: bridge: fix nd_tbl NULL dereference when IPv6 is disabledWhen booting with the 'ipv6.disable=1' parameter, the nd_tbl is neverinitialized because inet6_init() exits before ndisc_init() is calledwhich initializes it. Then, if neigh_suppress is enabled and an ICMPv6Neighbor Discovery packet reaches the bridge, br_do_suppress_nd() willdereference ipv6_stub->nd_tbl which is NULL, passing it toneigh_lookup(). This causes a kernel NULL pointer dereference.

CVE-2026-23383 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf, arm64: Force 8-byte alignment for JIT buffer to prevent atomic tearingstruct bpf_plt contains a u64 target field. Currently, the BPF JITallocator requests an alignment of 4 bytes (sizeof(u32)) for the JITbuffer.Because the base address of the JIT buffer can be 4-byte aligned (e.g.,ending in 0x4 or 0xc), the relative padding logic in build_plt() failsto ensure that target lands on an 8-byte boundary.This leads to two issues:1. UBSAN reports misaligned-access warnings when dereferencing the structure.2. More critically, target is updated concurrently via WRITE_ONCE() in bpf_arch_text_poke() while the JIT'd code executes ldr. On arm64, 64-bit loads/stores are only guaranteed to be single-copy atomic if they are 64-bit aligned. A misaligned target risks a torn read, causing the JIT to jump to a corrupted address.Fix this by increasing the allocation alignment requirement to 8 bytes(sizeof(u64)) in bpf_jit_binary_pack_alloc(). This anchors the base ofthe JIT buffer to an 8-byte boundary, allowing the relative padding mathin build_plt() to correctly align the target field.

Description: In the Linux kernel, the following vulnerability has been resolved:gve: fix incorrect buffer cleanup in gve_tx_clean_pending_packets for QPLIn DQ-QPL mode, gve_tx_clean_pending_packets() incorrectly uses the RDAbuffer cleanup path. 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.

Description: In the context switch logic Xen attempts to skip an IBPB in the case ofa vCPU returning to a CPU on which it was the previous vCPU to run.While safe for Xen's isolation between vCPUs, this prevents the guestkernel correctly isolating between tasks. Consider: 1) vCPU runs on CPU A, running task 1. 2) vCPU moves to CPU B, idle gets scheduled on A. Xen skips IBPB. 3) On CPU B, guest kernel switches from task 1 to 2, issuing IBPB. 4) vCPU moves back to CPU A. Xen skips IBPB again.Now, task 2 is running on CPU A with task 1's training still in the BTB.

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.

Description: systemd, a system and service manager, (as PID 1) hits an assert and freezes execution when an unprivileged IPC API call is made with spurious data. On version v249 and older the effect is not an assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is not possible as the safety check causes an assert instead. This IPC call was added in v239, so versions older than that are not affected. Versions 260-rc1, 259.2, 258.5, and 257.11 contain patches. No known workarounds are available.

CVE-2026-31411 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: atm: fix crash due to unvalidated vcc pointer in sigd_send()Reproducer available at [1].The ATM send path (sendmsg -> vcc_sendmsg -> sigd_send) reads the vccpointer from msg->vcc and uses it directly without any validation. Thispointer comes from userspace via sendmsg() and can be arbitrarily forged: int fd = socket(AF_ATMSVC, SOCK_DGRAM, 0); ioctl(fd, ATMSIGD_CTRL); // become ATM signaling daemon struct msghdr msg = { .msg_iov = &iov, ... }; *(unsigned long *)(buf + 4) = 0xdeadbeef; // fake vcc pointer sendmsg(fd, &msg, 0); // kernel dereferences 0xdeadbeefIn normal operation, the kernel sends the vcc pointer to the signalingdaemon via sigd_enq() when processing operations like connect(), bind(),or listen(). The daemon is expected to return the same pointer whenresponding. However, a malicious daemon can send arbitrary pointer values.Fix this by introducing find_get_vcc() which validates the pointer bysearching through vcc_hash (similar to how sigd_close() iterates overall VCCs), and acquires a reference via sock_hold() if found.Since struct atm_vcc embeds struct sock as its first member, they sharethe same lifetime. Therefore using sock_hold/sock_put is sufficient tokeep the vcc alive while it is being used.Note that there may be a race with sigd_close() which could mark the vccwith various flags (e.g., ATM_VF_RELEASED) after find_get_vcc() returns.However, sock_hold() guarantees the memory remains valid, so this raceonly affects the logical state, not memory safety.[1]: https://gist.github.com/mrpre/1ba5949c45529c511152e2f4c755b0f3

Description: In the Linux kernel, the following vulnerability has been resolved:bridge: mrp: reject zero test interval to avoid OOM panicbr_mrp_start_test() and br_mrp_start_in_test() accept the user-suppliedinterval value from netlink without validation. When interval is 0,usecs_to_jiffies(0) yields 0, causing the delayed work(br_mrp_test_work_expired / br_mrp_in_test_work_expired) to rescheduleitself with zero delay. This creates a tight loop on system_percpu_wqthat allocates and transmits MRP test frames at maximum rate, exhaustingall system memory and causing a kernel panic via OOM deadlock.The same zero-interval issue applies to br_mrp_start_in_test_parse()for interconnect test frames.Use NLA_POLICY_MIN(NLA_U32, 1) in the nla_policy tables for bothIFLA_BRIDGE_MRP_START_TEST_INTERVAL andIFLA_BRIDGE_MRP_START_IN_TEST_INTERVAL, so zero is rejected at thenetlink attribute parsing layer before the value ever reaches theworkqueue scheduling code. This is consistent with how other bridgesubsystems (br_fdb, br_mst) enforce range constraints on netlinkattributes.

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: In the Linux kernel, the following vulnerability has been resolved:net: skb: fix cross-cache free of KFENCE-allocated skb headSKB_SMALL_HEAD_CACHE_SIZE is intentionally set to a non-power-of-2value (e.g. 704 on x86_64) to avoid collisions with generic kmallocbucket sizes. This ensures that skb_kfree_head() can reliably useskb_end_offset to distinguish skb heads allocated fromskb_small_head_cache vs. generic kmalloc caches.However, when KFENCE is enabled, kfence_ksize() returns the exactrequested allocation size instead of the slab bucket size. If a caller(e.g. bpf_test_init) allocates skb head data via kzalloc() and therequested size happens to equal SKB_SMALL_HEAD_CACHE_SIZE, thenslab_build_skb() -> ksize() returns that exact value. After subtractingskb_shared_info overhead, skb_end_offset ends up matchingSKB_SMALL_HEAD_HEADROOM, causing skb_kfree_head() to incorrectly freethe object to skb_small_head_cache instead of back to the originalkmalloc cache, resulting in a slab cross-cache free: kmem_cache_free(skbuff_small_head): Wrong slab cache. Expected skbuff_small_head but got kmalloc-1kFix this by always calling kfree(head) in skb_kfree_head(). This keepsthe free path generic and avoids allocator-specific misclassificationfor KFENCE objects.

Description: In the Linux kernel, the following vulnerability has been resolved:ksmbd: fix use-after-free and NULL deref in smb_grant_oplock()smb_grant_oplock() has two issues in the oplock publication sequence:1) opinfo is linked into ci->m_op_list (via opinfo_add) before add_lease_global_list() is called. If add_lease_global_list() fails (kmalloc returns NULL), the error path frees the opinfo via __free_opinfo() while it is still linked in ci->m_op_list. Concurrent m_op_list readers (opinfo_get_list, or direct iteration in smb_break_all_levII_oplock) dereference the freed node.2) opinfo->o_fp is assigned after add_lease_global_list() publishes the opinfo on the global lease list. A concurrent find_same_lease_key() can walk the lease list and dereference opinfo->o_fp->f_ci while o_fp is still NULL.Fix by restructuring the publication sequence to eliminate post-publishfailure:- Set opinfo->o_fp before any list publication (fixes NULL deref).- Preallocate lease_table via alloc_lease_table() before opinfo_add() so add_lease_global_list() becomes infallible after publication.- Keep the original m_op_list publication order (opinfo_add before lease list) so concurrent opens via same_client_has_lease() and opinfo_get_list() still see the in-flight grant.- Use opinfo_put() instead of __free_opinfo() on err_out so that the RCU-deferred free path is used.This also requires splitting add_lease_global_list() to take apreallocated lease_table and changing its return type from int to void,since it can no longer fail.

Mount filesystem with inode that has inline flag set and small size2. truncate(file, 50MB) - grows size but inline flag remains set3. sendfile() attempts to write data4. ext4_write_inline_data() hits BUG_ON(write_size > inline_capacity)The crash occurs because ext4_write_inline_data() expects inline storageto accommodate the write, but the actual inline capacity (~60 bytes fori_block + ~96 bytes for xattrs) is far smaller than the file size andwrite request.The fix checks if the new size from setattr exceeds the inode's actualinline capacity (EXT4_I(inode)->i_inline_size) and converts the file toextent-based storage before proceeding with the size change.This addresses the root cause by ensuring the inline data flag and filesize remain consistent during truncate operations.

Description: In the Linux kernel, the following vulnerability has been resolved:xfs: avoid dereferencing log items after push callbacksAfter xfsaild_push_item() calls iop_push(), the log item may have beenfreed if the AIL lock was dropped during the push. Background inodereclaim or the dquot shrinker can free the log item while the AIL lockis not held, and the tracepoints in the switch statement dereferencethe log item after iop_push() returns.Fix this by capturing the log item type, flags, and LSN before callingxfsaild_push_item(), and introducing a new xfs_ail_push_class traceevent class that takes these pre-captured values and the ailp pointerinstead of the log item pointer.

Description: In the Linux kernel, the following vulnerability has been resolved:ksmbd: do not expire session on binding failureWhen a multichannel session binding request fails (e.g. wrong password),the error path unconditionally sets sess->state = SMB2_SESSION_EXPIRED.However, during binding, sess points to the target session looked up viaksmbd_session_lookup_slowpath() -- which belongs to another connection'suser. This allows a remote attacker to invalidate any active session bysimply sending a binding request with a wrong password (DoS).Fix this by skipping session expiration when the failed request wasa binding attempt, since the session does not belong to the currentconnection. The reference taken by ksmbd_session_lookup_slowpath() isstill correctly released via ksmbd_user_session_put().

Description: In the Linux kernel, the following vulnerability has been resolved:ksmbd: fix memory leaks and NULL deref in smb2_lock()smb2_lock() has three error handling issues after list_del() detachessmb_lock from lock_list at no_check_cl:1) If vfs_lock_file() returns an unexpected error in the non-UNLOCK path, goto out leaks smb_lock and its flock because the out: handler only iterates lock_list and rollback_list, neither of which contains the detached smb_lock.2) If vfs_lock_file() returns -ENOENT in the UNLOCK path, goto out leaks smb_lock and flock for the same reason. The error code returned to the dispatcher is also stale.3) In the rollback path, smb_flock_init() can return NULL on allocation failure. The result is dereferenced unconditionally, causing a kernel NULL pointer dereference. Add a NULL check to prevent the crash and clean up the bookkeeping; the VFS lock itself cannot be rolled back without the allocation and will be released at file or connection teardown.Fix cases 1 and 2 by hoisting the locks_free_lock()/kfree() to beforethe if(!rc) check in the UNLOCK branch so all exit paths share onefree site, and by freeing smb_lock and flock before goto out in thenon-UNLOCK branch. Propagate the correct error code in both cases.Fix case 3 by wrapping the VFS unlock in an if(rlock) guard and addinga NULL check for locks_free_lock(rlock) in the shared cleanup.Found via call-graph analysis using sqry.

It shouldn't be invalid since this is a re-insertion, so must haveworked before. Leaving the likely culprit as something already placedwhere we want to insert the vma.Following from that, for the case where we do something like a rebind inthe middle of a vma, and one or both mapped ends are already compatible,we skip doing the rebind of those vma and set next/prev to NULL. As wellas then adjust the original unmap va range, to avoid unmapping the ends.However, if we trigger the unwind path, we end up with three va, withthe two ends never being removed and the original va range in the middlestill being the shrunken size.If this occurs, one failure mode is when another unwind op needs tointeract with that range, which can happen with a vector of binds. Forexample, if we need to re-insert something in place of the original va.In this case the va is still the shrunken version, so when removing itand then doing a re-insert it can overlap with the ends, which werenever removed, triggering a warning like above, plus leaving the vm in abad state.With that, we need two things here: 1) Stop nuking the prev/next tracking for the skip cases. Instead relying on checking for skip prev/next, where needed. That way on the unwind path, we now correctly remove both ends. 2) Undo the unmap va shrinkage, on the unwind path. With the two ends now removed the unmap va should expand back to the original size again, before re-insertion.v2: - Update the explanation in the commit message, based on an actual IGT of triggering this issue, rather than conjecture. - Also undo the unmap shrinkage, for the skip case. With the two ends now removed, the original unmap va range should expand back to the original range.v3: - Track the old start/range separately. vma_size/start() uses the va info directly.(cherry picked from commit aec6969f75afbf4e01fd5fb5850ed3e9c27043ac)

CVE-2026-31486 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:hwmon: (pmbus/core) Protect regulator operations with mutexThe regulator operations pmbus_regulator_get_voltage(),pmbus_regulator_set_voltage(), and pmbus_regulator_list_voltage()access PMBus registers and shared data but were not protected bythe update_lock mutex. This could lead to race conditions.However, adding mutex protection directly to these functions causesa deadlock because pmbus_regulator_notify() (which callsregulator_notifier_call_chain()) is often called with the mutexalready held (e.g., from pmbus_fault_handler()). If a regulatorcallback then calls one of the now-protected voltage functions,it will attempt to acquire the same mutex.Rework pmbus_regulator_notify() to utilize a worker function tosend notifications outside of the mutex protection. Events arestored as atomics in a per-page bitmask and processed by the worker.Initialize the worker and its associated data during regulatorregistration, and ensure it is cancelled on device removal usingdevm_add_action_or_reset().While at it, remove the unnecessary include of linux/of.h.

CVE-2026-31519 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: set BTRFS_ROOT_ORPHAN_CLEANUP during subvol createWe have recently observed a number of subvolumes with broken dentries.ls-ing the parent dir looks like:drwxrwxrwt 1 root root 16 Jan 23 16:49 .drwxr-xr-x 1 root root 24 Jan 23 16:48 ..d????????? ? ? ? ? ? broken_subvoland similarly stat-ing the file fails.In this state, deleting the subvol fails with ENOENT, but attempting tocreate a new file or subvol over it errors out with EEXIST and evenaborts the fs. Which leaves us a bit stuck.dmesg contains a single notable error message reading:"could not do orphan cleanup -2"2 is ENOENT and the error comes from the failure handling path ofbtrfs_orphan_cleanup(), with the stack leading back up tobtrfs_lookup().btrfs_lookupbtrfs_lookup_dentrybtrfs_orphan_cleanup // prints that message and returns -ENOENTAfter some detailed inspection of the internal state, it became clearthat:- there are no orphan items for the subvol- the subvol is otherwise healthy looking, it is not half-deleted or anything, there is no drop progress, etc.- the subvol was created a while ago and does the meaningful first btrfs_orphan_cleanup() call that sets BTRFS_ROOT_ORPHAN_CLEANUP much later.- after btrfs_orphan_cleanup() fails, btrfs_lookup_dentry() returns -ENOENT, which results in a negative dentry for the subvolume via d_splice_alias(NULL, dentry), leading to the observed behavior. The bug can be mitigated by dropping the dentry cache, at which point we can successfully delete the subvolume if we want.i.e.,btrfs_lookup() btrfs_lookup_dentry() if (!sb_rdonly(inode->vfs_inode)->vfs_inode) btrfs_orphan_cleanup(sub_root) test_and_set_bit(BTRFS_ROOT_ORPHAN_CLEANUP) btrfs_search_slot() // finds orphan item for inode N ... prints "could not do orphan cleanup -2" if (inode == ERR_PTR(-ENOENT)) inode = NULL; return d_splice_alias(NULL, dentry) // NEGATIVE DENTRY for valid subvolumebtrfs_orphan_cleanup() does test_and_set_bit(BTRFS_ROOT_ORPHAN_CLEANUP)on the root when it runs, so it cannot run more than once on a givenroot, so something else must run concurrently. However, the obviousroutes to deleting an orphan when nlinks goes to 0 should not be able torun without first doing a lookup into the subvolume, which should runbtrfs_orphan_cleanup() and set the bit.The final important observation is that create_subvol() callsd_instantiate_new() but does not set BTRFS_ROOT_ORPHAN_CLEANUP, so ifthe dentry cache gets dropped, the next lookup into the subvolume willmake a real call into btrfs_orphan_cleanup() for the first time. Thisopens up the possibility of concurrently deleting the inode/orphan itemsbut most typical evict() paths will be holding a reference on the parentdentry (child dentry holds parent->d_lockref.count via dget ind_alloc(), released in __dentry_kill()) and prevent the parent frombeing removed from the dentry cache.The one exception is delayed iputs. Ordered extent creation callsigrab() on the inode. If the file is unlinked and closed while thoserefs are held, iput() in __dentry_kill() decrements i_count but doesnot trigger eviction (i_count > 0). The child dentry is freed and thesubvol dentry's d_lockref.count drops to 0, making it evictable whilethe inode is still alive.Since there are two races (the race between writeback and unlink andthe race between lookup and delayed iputs), and there are too many movingparts, the following three diagrams show the complete picture.(Only the second and third are races)Phase 1:Create Subvol in dentry cache without BTRFS_ROOT_ORPHAN_CLEANUP setbtrfs_mksubvol() lookup_one_len() __lookup_slow() d_alloc_parallel() __d_alloc() // d_lockref.count = 1 create_subvol(dentry) // doesn't touch the bit.. d_instantiate_new(dentry, inode) // dentry in cache with d_lockref.c---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/irdma: Fix deadlock during netdev reset with active connectionsResolve deadlock that occurs when user executes netdev reset while RDMAapplications (e.g., rping) are active. The netdev reset causes icedriver to remove irdma auxiliary driver, triggering device_delete andsubsequent client removal. During client removal, uverbs_client waitsfor QP reference count to reach zero while cma_client holds the finalreference, creating circular dependency and indefinite wait in iWARPmode. Skip QP reference count wait during device reset to preventdeadlock.

CVE-2026-31568 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:s390/mm: Add missing secure storage access fixups for donated memoryThere are special cases where secure storage access exceptions happenin a kernel context for pages that don't have the PG_arch_1 bitset. That bit is set for non-exported guest secure storage (memory)but is absent on storage donated to the Ultravisor since the kernelisn't allowed to export donated pages.Prior to this patch we would try to export the page by callingarch_make_folio_accessible() which would instantly return since thearch bit is absent signifying that the page was already exported andno further action is necessary. This leads to secure storage accessexception loops which can never be resolved.With this patch we unconditionally try to export and if that fails wefixup.

CVE-2026-31579 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wireguard: device: use exit_rtnl callback instead of manual rtnl_lock in pre_exitwg_netns_pre_exit() manually acquires rtnl_lock() inside thepernet .pre_exit callback. This causes a hung task when anotherthread holds rtnl_mutex - the cleanup_net workqueue (or thesetup_net failure rollback path) blocks indefinitely inwg_netns_pre_exit() waiting to acquire the lock.Convert to .exit_rtnl, introduced in commit 7a60d91c690b ("net:Add ->exit_rtnl() hook to struct pernet_operations."), where theframework already holds RTNL and batches all callbacks under asingle rtnl_lock()/rtnl_unlock() pair, eliminating the contentionwindow.The rcu_assign_pointer(wg->creating_net, NULL) is safe to movefrom .pre_exit to .exit_rtnl (which runs after synchronize_rcu())because all RCU readers of creating_net either use maybe_get_net()- which returns NULL for a dying namespace with zero refcount - oraccess net->user_ns which remains valid throughout the entireops_undo_list sequence.[ Jason: added __net_exit and __read_mostly annotations that were missing. ]

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: SEV: Drop WARN on large size for KVM_MEMORY_ENCRYPT_REG_REGIONDrop the WARN in sev_pin_memory() on npages overflowing an int, as theWARN is comically trivially to trigger from userspace, e.g. by doing: struct kvm_enc_region range = { .addr = 0, .size = -1ul, }; __vm_ioctl(vm, KVM_MEMORY_ENCRYPT_REG_REGION, &range);Note, the checks in sev_mem_enc_register_region() that presumably exist toverify the incoming address+size are completely worthless, as both "addr"and "size" are u64s and SEV is 64-bit only, i.e. they _can't_ be greaterthan ULONG_MAX. That wart will be cleaned up in the near future. if (range->addr > ULONG_MAX || range->size > ULONG_MAX) return -EINVAL;Opportunistically add a comment to explain why the code calculates thenumber of pages the "hard" way, e.g. instead of just shifting @ulen.

That assumption is toostrong for crafted filesystems because the JBD2-managed buffer pathcan bypass structural validation and return an invalid dinode to theresize ioctl.[FIX]Validate the dinode explicitly in ocfs2_group_extend(). If the globalbitmap buffer does not contain a valid dinode, report filesystemcorruption with ocfs2_error() and fail the resize operation instead ofcrashing the kernel.

Description: In the Linux kernel, the following vulnerability has been resolved:HID: core: clamp report_size in s32ton() to avoid undefined shifts32ton() shifts by n-1 where n is the field's report_size, a value thatcomes directly from a HID device. The HID parser bounds report_sizeonly to <= 256, so a broken HID device can supply a report descriptorwith a wide field that triggers shift exponents up to 256 on a 32-bittype when an output report is built via hid_output_field() orhid_set_field().Commit ec61b41918587 ("HID: core: fix shift-out-of-bounds inhid_report_raw_event") added the same n > 32 clamp to the functionsnto32(), but s32ton() was never given the same fix as I guess syzbothadn't figured out how to fuzz a device the same way.Fix this up by just clamping the max value of n, just like snto32()does.

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: proc: size address buffers for %pISpc outputThe AF_RXRPC procfs helpers format local and remote socket addresses intofixed 50-byte stack buffers with "%pISpc".That is too small for the longest current-tree IPv6-with-port form theformatter can produce. In lib/vsprintf.c, the compressed IPv6 path uses adotted-quad tail not only for v4mapped addresses, but also for ISATAPaddresses via ipv6_addr_is_isatap().As a result, a case such as [ffff:ffff:ffff:ffff:0:5efe:255.255.255.255]:65535is possible with the current formatter. That is 50 visible characters, so51 bytes including the trailing NUL, which does not fit in the existingchar[50] buffers used by net/rxrpc/proc.c.Size the buffers from the formatter's maximum textual form and switch thecall sites to scnprintf().Changes since v1:- correct the changelog to cite the actual maximum current-tree case explicitly- frame the proof around the ISATAP formatting path instead of the earlier mapped-v4 example

CVE-2026-31642 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: Fix call removal to use RCU safe deletionFix rxrpc call removal from the rxnet->calls list to use list_del_rcu()rather than list_del_init() to prevent stuffing up reading/proc/net/rxrpc/calls from potentially getting into an infinite loop.This, however, means that list_empty() no longer works on an entry that'sbeen deleted from the list, making it harder to detect prior deletion. Fixthis by:Firstly, make rxrpc_destroy_all_calls() only dump the first ten calls thatare unexpectedly still on the list. Limiting the number of steps meansthere's no need to call cond_resched() or to remove calls from the listhere, thereby eliminating the need for rxrpc_put_call() to check for that.rxrpc_put_call() can then be fixed to unconditionally delete the call fromthe list as it is the only place that the deletion occurs.

CVE-2026-31787 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:xen/privcmd: fix double free via VMA splittingprivcmd_vm_ops defines .close (privcmd_close), but neither .may_splitnor .open. When userspace does a partial munmap() on a privcmd mapping,the kernel splits the VMA via __split_vma(). Since may_split is NULL,the split is allowed. vm_area_dup() copies vm_private_data (a pagesarray allocated in alloc_empty_pages()) into the new VMA without anyfixup, because there is no .open callback.Both VMAs now point to the same pages array. When the unmapped portionis closed, privcmd_close() calls: - xen_unmap_domain_gfn_range() - xen_free_unpopulated_pages() - kvfree(pages)The surviving VMA still holds the dangling pointer. When it is laterdestroyed, the same sequence runs again, which leads to a double free.Fix this issue by adding a .may_split callback denying the VMA split.This is XSA-487 / CVE-2026-31787

CVE-2026-33947 Severity: Moderate CVSS3 score: 5.5

Description: jq is a command-line JSON processor. In versions 1.8.1 and below, functions jv_setpath(), jv_getpath(), and delpaths_sorted() in jq's src/jv_aux.c use unbounded recursion whose depth is controlled by the length of a caller-supplied path array, with no depth limit enforced. An attacker can supply a JSON document containing a flat array of ~65,000 integers (~200 KB) that, when used as a path argument by a trusted jq filter, exhausts the C call stack and crashes the process with a segmentation fault (SIGSEGV). This bypass works because the existing MAX_PARSING_DEPTH (10,000) limit only protects the JSON parser, not runtime path operations where arrays can be programmatically constructed to arbitrary lengths. The impact is denial of service (unrecoverable crash) affecting any application or service that processes untrusted JSON input through jq's setpath, getpath, or delpaths builtins. This issue has been addressed in commit fb59f1491058d58bdc3e8dd28f1773d1ac690a1f.

CVE-2026-39956 Severity: Moderate CVSS3 score: 5.5

Description: jq is a command-line JSON processor. In commits after 69785bf77f86e2ea1b4a20ca86775916889e91c9, the _strindices builtin in jq's src/builtin.c passes its arguments directly to jv_string_indexes() without verifying they are strings, and jv_string_indexes() in src/jv.c relies solely on assert() checks that are stripped in release builds compiled with -DNDEBUG. This allows an attacker to crash jq trivially with input like _strindices(0), and by crafting a numeric value whose IEEE-754 bit pattern maps to a chosen pointer, achieve a controlled pointer dereference and limited memory read/probe primitive. Any deployment that evaluates untrusted jq filters against a release build is vulnerable. This issue has been patched in commit fdf8ef0f0810e3d365cdd5160de43db46f57ed03.

CVE-2026-40164 Severity: Moderate CVSS3 score: 5.5

Description: jq is a command-line JSON processor. Before commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784, jq used MurmurHash3 with a hardcoded, publicly visible seed (0x432A9843) for all JSON object hash table operations, which allowed an attacker to precompute key collisions offline. By supplying a crafted JSON object (~100 KB) where all keys hashed to the same bucket, hash table lookups degraded from O(1) to O(n), turning any jq expression into an O(n^2) operation and causing significant CPU exhaustion. This affected common jq use cases such as CI/CD pipelines, web services, and data processing scripts, and was far more practical to exploit than existing heap overflow issues since it required only a small payload. This issue has been patched in commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784.

Description: In the Linux kernel, the following vulnerability has been resolved:ceph: fix race condition validating r_parent before applying stateAdd validation to ensure the cached parent directory inode matches thedirectory info in MDS replies. This prevents client-side race conditionswhere concurrent operations (e.g. rename) cause r_parent to become stalebetween request initiation and reply processing, which could lead toapplying state changes to incorrect directory inodes.[ idryomov: folded a kerneldoc fixup and a follow-up fix from Alex to move CEPH_CAP_PIN reference when r_parent is updated: When the parent directory lock is not held, req->r_parent can become stale and is updated to point to the correct inode. However, the associated CEPH_CAP_PIN reference was not being adjusted. The CEPH_CAP_PIN is a reference on an inode that is tracked for accounting purposes. Moving this pin is important to keep the accounting balanced. When the pin was not moved from the old parent to the new one, it created two problems: The reference on the old, stale parent was never released, causing a reference leak. A reference for the new parent was never acquired, creating the risk of a reference underflow later in ceph_mdsc_release_request(). This patch corrects the logic by releasing the pin from the old parent and acquiring it for the new parent when r_parent is switched. This ensures reference accounting stays balanced. ]

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: ensure no dirty metadata is written back for an fs with errors[BUG]During development of a minor feature (make sure all btrfs_bio::end_io()is called in task context), I noticed a crash in generic/388, wheremetadata writes triggered new works after btrfs_stop_all_workers().It turns out that it can even happen without any code modification, justusing RAID5 for metadata and the same workload from generic/388 is goingto trigger the use-after-free.[CAUSE]If btrfs hits an error, the fs is marked as error, no newtransaction is allowed thus metadata is in a frozen state.But there are some metadata modifications before that error, and they arestill in the btree inode page cache.Since there will be no real transaction commit, all those dirty foliosare just kept as is in the page cache, and they can not be invalidatedby invalidate_inode_pages2() call inside close_ctree(), because they aredirty.And finally after btrfs_stop_all_workers(), we call iput() on btreeinode, which triggers writeback of those dirty metadata.And if the fs is using RAID56 metadata, this will trigger RMW and queuenew works into rmw_workers, which is already stopped, causing warningfrom queue_work() and use-after-free.[FIX]Add a special handling for write_one_eb(), that if the fs is already inan error state, immediately mark the bbio as failure, instead of reallysubmitting them.Then during close_ctree(), iput() will just discard all those dirtytree blocks without really writing them back, thus no more new jobs foralready stopped-and-freed workqueues.The extra discard in write_one_eb() also acts as an extra safenet.E.g. the transaction abort is triggered by some extent/free spacetree corruptions, and since extent/free space tree is already corruptedsome tree blocks may be allocated where they shouldn't be (overwritingexisting tree blocks). In that case writing them back will furthercorrupting the fs.

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.

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-2025-71225 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:md: suspend array while updating raid_disks via sysfsIn raid1_reshape(), freeze_array() is called before modifying the r1biomemory pool (conf->r1bio_pool) and conf->raid_disks, andunfreeze_array() is called after the update is completed.However, freeze_array() only waits until nr_sync_pending and(nr_pending - nr_queued) of all buckets reaches zero. When an I/O erroroccurs, nr_queued is increased and the corresponding r1bio is queued toeither retry_list or bio_end_io_list. As a result, freeze_array() mayunblock before these r1bios are released.This can lead to a situation where conf->raid_disks and the mempool havealready been updated while queued r1bios, allocated with the oldraid_disks value, are later released. Consequently, free_r1bio() mayaccess memory out of bounds in put_all_bios() and release r1bios of thewrong size to the new mempool, potentially causing issues with themempool as well.Since only normal I/O might increase nr_queued while an I/O error occurs,suspending the array avoids this issue.Note: Updating raid_disks via ioctl SET_ARRAY_INFO already suspendsthe array. Therefore, we suspend the array when updating raid_disksvia sysfs to avoid this issue too.

CVE-2026-22979 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix memory leak in skb_segment_list for GRO packetsWhen skb_segment_list() is called during packet forwarding, it handlespackets that were aggregated by the GRO engine.Historically, the segmentation logic in skb_segment_list assumes thatindividual segments are split from a parent SKB and may need to carrytheir own socket memory accounting. Accordingly, the code transferstruesize from the parent to the newly created segments.Prior to commit ed4cccef64c1 ("gro: fix ownership transfer"), thistruesize subtraction in skb_segment_list() was valid because fragmentsstill carry a reference to the original socket.However, commit ed4cccef64c1 ("gro: fix ownership transfer") changedthis behavior by ensuring that fraglist entries are explicitlyorphaned (skb->sk = NULL) to prevent illegal orphaning later in thestack. This change meant that the entire socket memory charge remainedwith the head SKB, but the corresponding accounting logic inskb_segment_list() was never updated.As a result, the current code unconditionally adds each fragment'struesize to delta_truesize and subtracts it from the parent SKB. Sincethe fragments are no longer charged to the socket, this subtractionresults in an effective under-count of memory when the head is freed.This causes sk_wmem_alloc to remain non-zero, preventing socketdestruction and leading to a persistent memory leak.The leak can be observed via KMEMLEAK when tearing down the networkingenvironment:unreferenced object 0xffff8881e6eb9100 (size 2048): comm "ping", pid 6720, jiffies 4295492526 backtrace: kmem_cache_alloc_noprof+0x5c6/0x800 sk_prot_alloc+0x5b/0x220 sk_alloc+0x35/0xa00 inet6_create.part.0+0x303/0x10d0 __sock_create+0x248/0x640 __sys_socket+0x11b/0x1d0Since skb_segment_list() is exclusively used for SKB_GSO_FRAGLISTpackets constructed by GRO, the truesize adjustment is removed.The call to skb_release_head_state() must be preserved. As documented incommit cf673ed0e057 ("net: fix fraglist segmentation reference countleak"), it is still required to correctly drop references to SKBextensions that may be overwritten during __copy_skb_header().

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: qla2xxx: Sanitize payload size to prevent member overflowIn qla27xx_copy_fpin_pkt() and qla27xx_copy_multiple_pkt(), the frame_sizereported by firmware is used to calculate the copy length intoitem->iocb. However, the iocb member is defined as a fixed-size 64-bytearray within struct purex_item.If the reported frame_size exceeds 64 bytes, subsequent memcpy calls willoverflow the iocb member boundary. While extra memory might be allocated,this cross-member write is unsafe and triggers warnings underCONFIG_FORTIFY_SOURCE.Fix this by capping total_bytes to the size of the iocb member (64 bytes)before allocation and copying. This ensures all copies remain within thebounds of the destination structure member.

CVE-2026-23286 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:atm: lec: fix null-ptr-deref in lec_arp_clear_vccssyzkaller reported a null-ptr-deref in lec_arp_clear_vccs().This issue can be easily reproduced using the syzkaller reproducer.In the ATM LANE (LAN Emulation) module, the same atm_vcc can be shared bymultiple lec_arp_table entries (e.g., via entry->vcc or entry->recv_vcc).When the underlying VCC is closed, lec_vcc_close() iterates over allARP entries and calls lec_arp_clear_vccs() for each matched entry.For example, when lec_vcc_close() iterates through the hlists inpriv->lec_arp_empty_ones or other ARP tables:1. In the first iteration, for the first matched ARP entry sharing the VCC,lec_arp_clear_vccs() frees the associated vpriv (which is vcc->user_back)and sets vcc->user_back to NULL.2. In the second iteration, for the next matched ARP entry sharing the sameVCC, lec_arp_clear_vccs() is called again. It obtains a NULL vpriv fromvcc->user_back (via LEC_VCC_PRIV(vcc)) and then attempts to dereference itvia `vcc->pop = vpriv->old_pop`, leading to a null-ptr-deref crash.Fix this by adding a null check for vpriv before dereferencingit. If vpriv is already NULL, it means the VCC has been clearedby a previous call, so we can safely skip the cleanup and justclear the entry's vcc/recv_vcc pointers.The entire cleanup block (including vcc_release_async()) is placed insidethe vpriv guard because a NULL vpriv indicates the VCC has already beenfully released by a prior iteration - repeating the teardown wouldredundantly set flags and trigger callbacks on an already-closing socket.The Fixes tag points to the initial commit because the entry->vcc path hasbeen vulnerable since the original code. The entry->recv_vcc path was lateradded by commit 8d9f73c0ad2f ("atm: fix a memory leak of vcc->user_back")with the same pattern, and both paths are fixed here.

CVE-2026-32249 Severity: Moderate CVSS3 score: 5.3

Description: Vim is an open source, command line text editor. From 9.1.0011 to before 9.2.0137, Vim's NFA regex compiler, when encountering a collection containing a combining character as the endpoint of a character range (e.g. [0-0\u05bb]), incorrectly emits the composing bytes of that character as separate NFA states. This corrupts the NFA postfix stack, resulting in NFA_START_COLL having a NULL out1 pointer. When nfa_max_width() subsequently traverses the compiled NFA to estimate match width for the look-behind assertion, it dereferences state->out1->out without a NULL check, causing a segmentation fault. This vulnerability is fixed in 9.2.0137.

CVE-2026-33948 Severity: Moderate CVSS3 score: 5.3

Description: jq is a command-line JSON processor. Commits before 6374ae0bcdfe33a18eb0ae6db28493b1f34a0a5b contain a vulnerability where CLI input parsing allows validation bypass via embedded NUL bytes. When reading JSON from files or stdin, jq uses strlen() to determine buffer length instead of the actual byte count from fgets(), causing it to truncate input at the first NUL byte and parse only the preceding prefix. This enables an attacker to craft input with a benign JSON prefix before a NUL byte followed by malicious trailing data, where jq validates only the prefix as valid JSON while silently discarding the suffix. Workflows relying on jq to validate untrusted JSON before forwarding it to downstream consumers are susceptible to parser differential attacks, as those consumers may process the full input including the malicious trailing bytes. This issue has been patched by commit 6374ae0bcdfe33a18eb0ae6db28493b1f34a0a5b.

Introduce a new icc_bw_lock for cases wherewe need to serialize bw aggregation and update to decouple that frompaths that require memory allocation such as node/link creation/destruction.Fixes this lockdep splat: ====================================================== WARNING: possible circular locking dependency detected 6.2.0-rc8-debug+ #554 Not tainted ------------------------------------------------------ ring0/132 is trying to acquire lock: ffffff80871916d0 (&gmu->lock){+.+.}-{3:3}, at: a6xx_pm_resume+0xf0/0x234 but task is already holding lock: ffffffdb5aee57e8 (dma_fence_map){++++}-{0:0}, at: msm_job_run+0x68/0x150 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #4 (dma_fence_map){++++}-{0:0}: __dma_fence_might_wait+0x74/0xc0 dma_resv_lockdep+0x1f4/0x2f4 do_one_initcall+0x104/0x2bc kernel_init_freeable+0x344/0x34c kernel_init+0x30/0x134 ret_from_fork+0x10/0x20 -> #3 (mmu_notifier_invalidate_range_start){+.+.}-{0:0}: fs_reclaim_acquire+0x80/0xa8 slab_pre_alloc_hook.constprop.0+0x40/0x25c __kmem_cache_alloc_node+0x60/0x1cc __kmalloc+0xd8/0x100 topology_parse_cpu_capacity+0x8c/0x178 get_cpu_for_node+0x88/0xc4 parse_cluster+0x1b0/0x28c parse_cluster+0x8c/0x28c init_cpu_topology+0x168/0x188 smp_prepare_cpus+0x24/0xf8 kernel_init_freeable+0x18c/0x34c kernel_init+0x30/0x134 ret_from_fork+0x10/0x20 -> #2 (fs_reclaim){+.+.}-{0:0}: __fs_reclaim_acquire+0x3c/0x48 fs_reclaim_acquire+0x54/0xa8 slab_pre_alloc_hook.constprop.0+0x40/0x25c __kmem_cache_alloc_node+0x60/0x1cc __kmalloc+0xd8/0x100 kzalloc.constprop.0+0x14/0x20 icc_node_create_nolock+0x4c/0xc4 icc_node_create+0x38/0x58 qcom_icc_rpmh_probe+0x1b8/0x248 platform_probe+0x70/0xc4 really_probe+0x158/0x290 __driver_probe_device+0xc8/0xe0 driver_probe_device+0x44/0x100 __driver_attach+0xf8/0x108 bus_for_each_dev+0x78/0xc4 driver_attach+0x2c/0x38 bus_add_driver+0xd0/0x1d8 driver_register+0xbc/0xf8 __platform_driver_register+0x30/0x3c qnoc_driver_init+0x24/0x30 do_one_initcall+0x104/0x2bc kernel_init_freeable+0x344/0x34c kernel_init+0x30/0x134 ret_from_fork+0x10/0x20 -> #1 (icc_lock){+.+.}-{3:3}: __mutex_lock+0xcc/0x3c8 mutex_lock_nested+0x30/0x44 icc_set_bw+0x88/0x2b4 _set_opp_bw+0x8c/0xd8 _set_opp+0x19c/0x300 dev_pm_opp_set_opp+0x84/0x94 a6xx_gmu_resume+0x18c/0x804 a6xx_pm_resume+0xf8/0x234 adreno_runtime_resume+0x2c/0x38 pm_generic_runtime_resume+0x30/0x44 __rpm_callback+0x15c/0x174 rpm_callback+0x78/0x7c rpm_resume+0x318/0x524 __pm_runtime_resume+0x78/0xbc adreno_load_gpu+0xc4/0x17c msm_open+0x50/0x120 drm_file_alloc+0x17c/0x228 drm_open_helper+0x74/0x118 drm_open+0xa0/0x144 drm_stub_open+0xd4/0xe4 chrdev_open+0x1b8/0x1e4 do_dentry_open+0x2f8/0x38c vfs_open+0x34/0x40 path_openat+0x64c/0x7b4 do_filp_open+0x54/0xc4 do_sys_openat2+0x9c/0x100 do_sys_open+0x50/0x7c __arm64_sys_openat+0x28/0x34 invoke_syscall+0x8c/0x128 el0_svc_common.constprop.0+0xa0/0x11c do_el0_---truncated---

CVE-2025-40142 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: pcm: Disable bottom softirqs as part of spin_lock_irq() on PREEMPT_RTsnd_pcm_group_lock_irq() acquires a spinlock_t and disables interruptsvia spin_lock_irq(). This also implicitly disables the handling ofsoftirqs such as TIMER_SOFTIRQ.On PREEMPT_RT softirqs are preemptible and spin_lock_irq() does notdisable them. That means a timer can be invoked during spin_lock_irq()on the same CPU. Due to synchronisations reasons local_bh_disable() hasa per-CPU lock named softirq_ctrl.lock which synchronizes individualsoftirq against each other.syz-bot managed to trigger a lockdep report where softirq_ctrl.lock isacquired in hrtimer_cancel() in addition to hrtimer_run_softirq(). Thisis a possible deadlock.The softirq_ctrl.lock can not be made part of spin_lock_irq() as thiswould lead to too much synchronisation against individual threads on thesystem. To avoid the possible deadlock, softirqs must be manuallydisabled before the lock is acquired.Disable softirqs before the lock is acquired on PREEMPT_RT.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: qla2xxx: Clear cmds after chip resetCommit aefed3e5548f ("scsi: qla2xxx: target: Fix offline port handlingand host reset handling") caused two problems:1. Commands sent to FW, after chip reset got stuck and never freed as FW is not going to respond to them anymore.2. BUG_ON(cmd->sg_mapped) in qlt_free_cmd(). Commit 26f9ce53817a ("scsi: qla2xxx: Fix missed DMA unmap for aborted commands") attempted to fix this, but introduced another bug under different circumstances when two different CPUs were racing to call qlt_unmap_sg() at the same time: BUG_ON(!valid_dma_direction(dir)) in dma_unmap_sg_attrs().So revert "scsi: qla2xxx: Fix missed DMA unmap for aborted commands" andpartially revert "scsi: qla2xxx: target: Fix offline port handling andhost reset handling" at __qla2x00_abort_all_cmds.

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---

CVE-2025-68788 Severity: Moderate CVSS3 score: 4.7

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().

Description: In the Linux kernel, the following vulnerability has been resolved:ipv4: Fix reference count leak when using error routes with nexthop objectsWhen a nexthop object is deleted, it is marked as dead and thenfib_table_flush() is called to flush all the routes that are using thedead nexthop.The current logic in fib_table_flush() is to only flush error routes(e.g., blackhole) when it is called as part of network namespacedismantle (i.e., with flush_all=true). Therefore, error routes are notflushed when their nexthop object is deleted: # ip link add name dummy1 up type dummy # ip nexthop add id 1 dev dummy1 # ip route add 198.51.100.1/32 nhid 1 # ip route add blackhole 198.51.100.2/32 nhid 1 # ip nexthop del id 1 # ip route show blackhole 198.51.100.2 nhid 1 dev dummy1As such, they keep holding a reference on the nexthop object which inturn holds a reference on the nexthop device, resulting in a referencecount leak: # ip link del dev dummy1 [ 70.516258] unregister_netdevice: waiting for dummy1 to become free. Usage count = 2Fix by flushing error routes when their nexthop is marked as dead.IPv6 does not suffer from this problem.

Description: In the Linux kernel, the following vulnerability has been resolved:net: usb: rtl8150: fix memory leak on usb_submit_urb() failureIn async_set_registers(), when usb_submit_urb() fails, the allocated async_req structure and URB are not freed, causing a memory leak. The completion callback async_set_reg_cb() is responsible for freeing these allocations, but it is only called after the URB is successfully submitted and completes (successfully or with error). If submission fails, the callback never runs and the memory is leaked. Fix this by freeing both the URB and the request structure in the error path when usb_submit_urb() fails.

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-2026-23110 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: core: Wake up the error handler when final completions race against each otherThe fragile ordering between marking commands completed or failed sothat the error handler only wakes when the last running commandcompletes or times out has race conditions. These race conditions cancause the SCSI layer to fail to wake the error handler, leaving I/Othrough the SCSI host stuck as the error state cannot advance.First, there is an memory ordering issue within scsi_dec_host_busy().The write which clears SCMD_STATE_INFLIGHT may be reordered with readscounting in scsi_host_busy(). While the local CPU will see its ownwrite, reordering can allow other CPUs in scsi_dec_host_busy() orscsi_eh_inc_host_failed() to see a raised busy count, causing no CPU tosee a host busy equal to the host_failed count.This race condition can be prevented with a memory barrier on the errorpath to force the write to be visible before counting host busycommands.Second, there is a general ordering issue with scsi_eh_inc_host_failed(). Bycounting busy commands before incrementing host_failed, it can race with afinal command in scsi_dec_host_busy(), such that scsi_dec_host_busy() doesnot see host_failed incremented but scsi_eh_inc_host_failed() counts busycommands before SCMD_STATE_INFLIGHT is cleared by scsi_dec_host_busy(),resulting in neither waking the error handler task.This needs the call to scsi_host_busy() to be moved after host_failed isincremented to close the race condition.

CVE-2026-23198 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: Don't clobber irqfd routing type when deassigning irqfdWhen deassigning a KVM_IRQFD, don't clobber the irqfd's copy of the IRQ'srouting entry as doing so breaks kvm_arch_irq_bypass_del_producer() on x86and arm64, which explicitly look for KVM_IRQ_ROUTING_MSI. Instead, tohandle a concurrent routing update, verify that the irqfd is still activebefore consuming the routing information. As evidenced by the x86 andarm64 bugs, and another bug in kvm_arch_update_irqfd_routing() (see below),clobbering the entry type without notifying arch code is surprising anderror prone.As a bonus, checking that the irqfd is active provides a convenientlocation for documenting _why_ KVM must not consume the routing entry foran irqfd that is in the process of being deassigned: once the irqfd isdeleted from the list (which happens *before* the eventfd is detached), itwill no longer receive updates via kvm_irq_routing_update(), and so KVMcould deliver an event using stale routing information (relative toKVM_SET_GSI_ROUTING returning to userspace).As an even better bonus, explicitly checking for the irqfd being activefixes a similar bug to the one the clobbering is trying to prevent: if anirqfd is deactivated, and then its routing is changed,kvm_irq_routing_update() won't invoke kvm_arch_update_irqfd_routing()(because the irqfd isn't in the list). And so if the irqfd is in bypassmode, IRQs will continue to be posted using the old routing information.As for kvm_arch_irq_bypass_del_producer(), clobbering the routing typeresults in KVM incorrectly keeping the IRQ in bypass mode, which isespecially problematic on AMD as KVM tracks IRQs that are being posted toa vCPU in a list whose lifetime is tied to the irqfd.Without the help of KASAN to detect use-after-free, the most commonsympton on AMD is a NULL pointer deref in amd_iommu_update_ga() due tothe memory for irqfd structure being re-allocated and zeroed, resultingin irqfd->irq_bypass_data being NULL when read byavic_update_iommu_vcpu_affinity(): BUG: kernel NULL pointer dereference, address: 0000000000000018 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 40cf2b9067 P4D 40cf2b9067 PUD 408362a067 PMD 0 Oops: Oops: 0000 [#1] SMP CPU: 6 UID: 0 PID: 40383 Comm: vfio_irq_test Tainted: G U W O 6.19.0-smp--5dddc257e6b2-irqfd #31 NONE Tainted: [U]=USER, [W]=WARN, [O]=OOT_MODULE Hardware name: Google, Inc.

Description: In the Linux kernel, the following vulnerability has been resolved:spi: tegra210-quad: Protect curr_xfer check in IRQ handlerNow that all other accesses to curr_xfer are done under the lock,protect the curr_xfer NULL check in tegra_qspi_isr_thread() with thespinlock. Without this protection, the following race can occur: CPU0 (ISR thread) CPU1 (timeout path) ---------------- ------------------- if (!tqspi->curr_xfer) // sees non-NULL spin_lock() tqspi->curr_xfer = NULL spin_unlock() handle_*_xfer() spin_lock() t = tqspi->curr_xfer // NULL! ... t->len ... // NULL dereference!With this patch, all curr_xfer accesses are now properly synchronized.Although all accesses to curr_xfer are done under the lock, integra_qspi_isr_thread() it checks for NULL, releases the lock andreacquires it later in handle_cpu_based_xfer()/handle_dma_based_xfer().There is a potential for an update in between, which could cause a NULLpointer dereference.To handle this, add a NULL check inside the handlers after acquiringthe lock. This ensures that if the timeout path has already clearedcurr_xfer, the handler will safely return without dereferencing theNULL pointer.

This might lead to bandwidth accountingcorruption, as enqueue_task_dl() won't recognize the lock holder asboosted.The scenario occurs when:1. A DEADLINE task (donor) blocks on a PI mutex held by another DEADLINE task (holder), but the holder doesn't inherit parameters (e.g., it already has a shorter deadline)2. sched_setscheduler() changes the holder from DEADLINE to a lower class while still holding the mutex3. The holder should now inherit DEADLINE parameters from the donor and be enqueued with ENQUEUE_REPLENISH, but this doesn't happenFix the issue by introducing __setscheduler_dl_pi(), which detects whena DEADLINE (proper or boosted) task gets setscheduled to a lowerpriority class. In case, the function makes the task inherit DEADLINEparameters of the donoer (pi_se) and sets ENQUEUE_REPLENISH flag toensure proper bandwidth accounting during the next enqueue operation.

Oncetls_decrypt_async_wait() returns, every AEAD operationhas completed and the engine no longer references thoseskbs, so they can be freed unconditionally.A subsequent patch adds batch async decryption totls_sw_read_sock(), introducing a new call site thatmust drain pending AEAD operations and release heldskbs. Move __skb_queue_purge(&ctx->async_hold) intotls_decrypt_async_wait() so the purge is centralizedand every caller -- recvmsg's drain path, the -EBUSYfallback in tls_do_decryption(), and the new read_sockbatch path -- releases held skbs on synchronizationwithout each site managing the purge independently.This fixes a leak when tls_strp_msg_hold() fails part-way through,after having added some cloned skbs to the async_holdqueue. tls_decrypt_sg() will then call tls_decrypt_async_wait() toprocess all pending decrypts, and drop back to synchronous mode, buttls_sw_recvmsg() only flushes the async_hold queue when one record hasbeen processed in "fully-async" mode, which may not be the case here.[pabeni@redhat.com: added leak comment]

CVE-2026-23440 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5e: Fix race condition during IPSec ESN updateIn IPSec full offload mode, the device reports an ESN (ExtendedSequence Number) wrap event to the driver. The driver validates thisevent by querying the IPSec ASO and checking that the esn_event_armfield is 0x0, which indicates an event has occurred. After handlingthe event, the driver must re-arm the context by setting esn_event_armback to 0x1.A race condition exists in this handling path. After validating theevent, the driver calls mlx5_accel_esp_modify_xfrm() to update thekernel's xfrm state. This function temporarily releases andre-acquires the xfrm state lock.So, need to acknowledge the event first by setting esn_event_arm to0x1. This prevents the driver from reprocessing the same ESN update ifthe hardware sends events for other reason. Since the next ESN updateonly occurs after nearly 2^31 packets are received, there's no risk ofmissing an update, as it will happen long after this handling hasfinished.Processing the event twice causes the ESN high-order bits (esn_msb) tobe incremented incorrectly. The driver then programs the hardware withthis invalid ESN state, which leads to anti-replay failures and acomplete halt of IPSec traffic.Fix this by re-arming the ESN event immediately after it is validated,before calling mlx5_accel_esp_modify_xfrm(). This ensures that anyspurious, duplicate events are correctly ignored, closing the racewindow.

CVE-2026-23473 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring/poll: fix multishot recv missing EOF on wakeup raceWhen a socket send and shutdown() happen back-to-back, both firewake-ups before the receiver's task_work has a chance to run. The firstwake gets poll ownership (poll_refs=1), and the second bumps it to 2.When io_poll_check_events() runs, it calls io_poll_issue() which does arecv that reads the data and returns IOU_RETRY. The loop then drains allaccumulated refs (atomic_sub_return(2) -> 0) and exits, even though onlythe first event was consumed. Since the shutdown is a persistent statechange, no further wakeups will happen, and the multishot recv can hangforever.Check specifically for HUP in the poll loop, and ensure that anotherloop is done to check for status if more than a single poll activationis pending. This ensures we don't lose the shutdown event.

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-2026-31404 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:NFSD: Defer sub-object cleanup in export put callbackssvc_export_put() calls path_put() and auth_domain_put() immediatelywhen the last reference drops, before the RCU grace period. RCUreaders in e_show() and c_show() access both ex_path (viaseq_path/d_path) and ex_client->name (via seq_escape) withoutholding a reference. If cache_clean removes the entry and drops thelast reference concurrently, the sub-objects are freed while stillin use, producing a NULL pointer dereference in d_path.Commit 2530766492ec ("nfsd: fix UAF when access ex_uuid orex_stats") moved kfree of ex_uuid and ex_stats into thecall_rcu callback, but left path_put() and auth_domain_put() runningbefore the grace period because both may sleep and call_rcucallbacks execute in softirq context.Replace call_rcu/kfree_rcu with queue_rcu_work(), which defers thecallback until after the RCU grace period and executes it in processcontext where sleeping is permitted. This allows path_put() andauth_domain_put() to be moved into the deferred callback alongsidethe other resource releases. Apply the same fix to expkey_put(),which has the identical pattern with ek_path and ek_client.A dedicated workqueue scopes the shutdown drain to only NFSDexport release work items; flushing the sharedsystem_unbound_wq would stall on unrelated work from othersubsystems. nfsd_export_shutdown() uses rcu_barrier() followedby flush_workqueue() to ensure all deferred release callbackscomplete before the export caches are destroyed.Reviwed-by: Jeff Layton

Description: In the Linux kernel, the following vulnerability has been resolved:pmdomain: bcm: bcm2835-power: Increase ASB control timeoutThe bcm2835_asb_control() function uses a tight polling loop to waitfor the ASB bridge to acknowledge a request. During intensive workloads,this handshake intermittently fails for V3D's master ASB on BCM2711,resulting in "Failed to disable ASB master for v3d" errors duringruntime PM suspend. As a consequence, the failed power-off leaves V3D ina broken state, leading to bus faults or system hangs on later accesses.As the timeout is insufficient in some scenarios, increase the pollingtimeout from 1us to 5us, which is still negligible in the context of apower domain transition. Also, replace the open-coded ktime_get_ns()/cpu_relax() polling loop with readl_poll_timeout_atomic().

When only an ACL is present,the function returns false, nfsd_setattr() is skipped, and thePOSIX ACL is never applied to the inode.Subsequently, when the client retrieves the ACL, the server findsno POSIX ACL on the inode and returns one generated from the file'smode bits rather than returning the originally-specified ACL.

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.

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:spi: spi-sprd-adi: Fix double free in probe error pathThe driver currently uses spi_alloc_host() to allocate the controllerbut registers it using devm_spi_register_controller().If devm_register_restart_handler() fails, the code jumps to theput_ctlr label and calls spi_controller_put(). However, since thecontroller was registered via a devm function, the device core willautomatically call spi_controller_put() again when the probe fails.This results in a double-free of the spi_controller structure.Fix this by switching to devm_spi_alloc_host() and removing themanual spi_controller_put() call.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amdgpu: fix NULL pointer dereference in amdgpu_gmc_filter_faults_removeOn APUs such as Raven and Renoir (GC 9.1.0, 9.2.2, 9.3.0), the ih1 andih2 interrupt ring buffers are not initialized. This is by design, asthese secondary IH rings are only available on discrete GPUs. Seevega10_ih_sw_init() which explicitly skips ih1/ih2 initialization whenAMD_IS_APU is set.However, amdgpu_gmc_filter_faults_remove() unconditionally uses ih1 toget the timestamp of the last interrupt entry. When retry faults areenabled on APUs (noretry=0), this function is called from the SVM pagefault recovery path, resulting in a NULL pointer dereference whenamdgpu_ih_decode_iv_ts_helper() attempts to access ih->ring[].The crash manifests as: BUG: kernel NULL pointer dereference, address: 0000000000000004 RIP: 0010:amdgpu_ih_decode_iv_ts_helper+0x22/0x40 [amdgpu] Call Trace: amdgpu_gmc_filter_faults_remove+0x60/0x130 [amdgpu] svm_range_restore_pages+0xae5/0x11c0 [amdgpu] amdgpu_vm_handle_fault+0xc8/0x340 [amdgpu] gmc_v9_0_process_interrupt+0x191/0x220 [amdgpu] amdgpu_irq_dispatch+0xed/0x2c0 [amdgpu] amdgpu_ih_process+0x84/0x100 [amdgpu]This issue was exposed by commit 1446226d32a4 ("drm/amdgpu: Remove GC HWIP 9.3.0 from noretry=1") which changed the default for Renoir APU fromnoretry=1 to noretry=0, enabling retry fault handling and thusexercising the buggy code path.Fix this by adding a check for ih1.ring_size before attempting to useit.

CVE-2026-23213 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amd/pm: Disable MMIO access during SMU Mode 1 resetDuring Mode 1 reset, the ASIC undergoes a reset cycle and becomestemporarily inaccessible via PCIe. Any attempt to access MMIO registersduring this window (e.g., from interrupt handlers or other driver threads)can result in uncompleted PCIe transactions, leading to NMI panics orsystem hangs.To prevent this, set the `no_hw_access` flag to true immediately aftertriggering the reset. This signals other driver components to skipregister accesses while the device is offline.A memory barrier `smp_mb()` is added to ensure the flag update isglobally visible to all cores before the driver enters the sleep/waitstate.(cherry picked from commit 7edb503fe4b6d67f47d8bb0dfafb8e699bb0f8a4)

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: target: Fix recursive locking in __configfs_open_file()In flush_write_buffer, &p->frag_sem is acquired and then the loaded storefunction is called, which, here, is target_core_item_dbroot_store(). Thisfunction called filp_open(), following which these functions were called(in reverse order), according to the call trace: down_read __configfs_open_file do_dentry_open vfs_open do_open path_openat do_filp_open file_open_name filp_open target_core_item_dbroot_store flush_write_buffer configfs_write_itertarget_core_item_dbroot_store() tries to validate the new file path bytrying to open the file path provided to it; however, in this case, the bugreport shows:db_root: not a directory: /sys/kernel/config/target/dbrootindicating that the same configfs file was tried to be opened, on which itis currently working on. Thus, it is trying to acquire frag_sem semaphoreof the same file of which it already holds the semaphore obtained inflush_write_buffer(), leading to acquiring the semaphore in a nested mannerand a possibility of recursive locking.Fix this by modifying target_core_item_dbroot_store() to use kern_path()instead of filp_open() to avoid opening the file using filesystem-specificfunction __configfs_open_file(), and further modifying it to make this fixcompatible.

CVE-2026-23300 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:net: ipv6: fix panic when IPv4 route references loopback IPv6 nexthopWhen a standalone IPv6 nexthop object is created with a loopback device(e.g., "ip -6 nexthop add id 100 dev lo"), fib6_nh_init() misclassifiesit as a reject route. This is because nexthop objects have no destinationprefix (fc_dst=::), causing fib6_is_reject() to match any loopbacknexthop. The reject path skips fib_nh_common_init(), leavingnhc_pcpu_rth_output unallocated. If an IPv4 route later references thisnexthop, __mkroute_output() dereferences NULL nhc_pcpu_rth_output andpanics.Simplify the check in fib6_nh_init() to only match explicit rejectroutes (RTF_REJECT) instead of using fib6_is_reject(). The loopbackpromotion heuristic in fib6_is_reject() is handled separately byip6_route_info_create_nh(). After this change, the three cases behaveas follows:1. Explicit reject route ("ip -6 route add unreachable 2001:db8::/64"): RTF_REJECT is set, enters reject path, skips fib_nh_common_init(). No behavior change.2. Implicit loopback reject route ("ip -6 route add 2001:db8::/32 dev lo"): RTF_REJECT is not set, takes normal path, fib_nh_common_init() is called. ip6_route_info_create_nh() still promotes it to reject afterward. nhc_pcpu_rth_output is allocated but unused, which is harmless.3. Standalone nexthop object ("ip -6 nexthop add id 100 dev lo"): RTF_REJECT is not set, takes normal path, fib_nh_common_init() is called. nhc_pcpu_rth_output is properly allocated, fixing the crash when IPv4 routes reference this nexthop.

CVE-2026-23310 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:bpf/bonding: reject vlan+srcmac xmit_hash_policy change when XDP is loadedbond_option_mode_set() already rejects mode changes that would make aloaded XDP program incompatible via bond_xdp_check(). However,bond_option_xmit_hash_policy_set() has no such guard.For 802.3ad and balance-xor modes, bond_xdp_check() returns false whenxmit_hash_policy is vlan+srcmac, because the 802.1q payload is usuallyabsent due to hardware offload. This means a user can:1. Attach a native XDP program to a bond in 802.3ad/balance-xor mode with a compatible xmit_hash_policy (e.g. layer2+3).2. Change xmit_hash_policy to vlan+srcmac while XDP remains loaded.This leaves bond->xdp_prog set but bond_xdp_check() now returning falsefor the same device. When the bond is later destroyed, dev_xdp_uninstall()calls bond_xdp_set(dev, NULL, NULL) to remove the program, which hitsthe bond_xdp_check() guard and returns -EOPNOTSUPP, triggering:WARN_ON(dev_xdp_install(dev, mode, bpf_op, NULL, 0, NULL))Fix this by rejecting xmit_hash_policy changes to vlan+srcmac when anXDP program is loaded on a bond in 802.3ad or balance-xor mode.commit 39a0876d595b ("net, bonding: Disallow vlan+srcmac with XDP")introduced bond_xdp_check() which returns false for 802.3ad/balance-xormodes when xmit_hash_policy is vlan+srcmac. The check was wired intobond_xdp_set() to reject XDP attachment with an incompatible policy, butthe symmetric path -- preventing xmit_hash_policy from being changed to anincompatible value after XDP is already loaded -- was left unguarded inbond_option_xmit_hash_policy_set().Note:commit 094ee6017ea0 ("bonding: check xdp prog when set bond mode")later added a similar guard to bond_option_mode_set(), butbond_option_xmit_hash_policy_set() remained unprotected.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:seg6: separate dst_cache for input and output paths in seg6 lwtunnelThe seg6 lwtunnel uses a single dst_cache per encap route, sharedbetween seg6_input_core() and seg6_output_core(). These two pathscan perform the post-encap SID lookup in different routing contexts(e.g., ip rules matching on the ingress interface, or VRF tableseparation). Whichever path runs first populates the cache, and theother reuses it blindly, bypassing its own lookup.Fix this by splitting the cache into cache_input and cache_output,so each path maintains its own cached dst independently.

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.

When thedevice reports zero interfaces (either due to hardware configurationor firmware issues), kcalloc(0, ...) returns ZERO_SIZE_PTR (0x10)instead of NULL.Later in dpaa2_switch_probe(), the NAPI initialization unconditionallyaccesses ethsw->ports[0]->netdev, which attempts to dereferenceZERO_SIZE_PTR (address 0x10), resulting in a kernel panic.Add a check to ensure num_ifs is greater than zero after retrievingdevice attributes.

Description: Vim is an open source, command line text editor. Prior to version 9.1.1551, a path traversal issue in Vim's zip.vim plugin can allow overwriting of arbitrary files when opening specially crafted zip archives. Impact is low because this exploit requires direct user interaction. However, successfully exploitation can lead to overwriting sensitive files or placing executable code in privileged locations, depending on the permissions of the process editing the archive. The victim must edit such a file using Vim which will reveal the filename and the file content, a careful user may suspect some strange things going on. Successful exploitation could results in the ability to execute arbitrary commands on the underlying operating system. Version 9.1.1551 contains a patch for the vulnerability.

Description: In the Linux kernel, the following vulnerability has been resolved:net: nfc: fix deadlock between nfc_unregister_device and rfkill_fop_writeA deadlock can occur between nfc_unregister_device() and rfkill_fop_write()due to lock ordering inversion between device_lock and rfkill_global_mutex.The problematic lock order is:Thread A (rfkill_fop_write): rfkill_fop_write() mutex_lock(&rfkill_global_mutex) rfkill_set_block() nfc_rfkill_set_block() nfc_dev_down() device_lock(&dev->dev) <- waits for device_lockThread B (nfc_unregister_device): nfc_unregister_device() device_lock(&dev->dev) rfkill_unregister() mutex_lock(&rfkill_global_mutex) <- waits for rfkill_global_mutexThis creates a classic ABBA deadlock scenario.Fix this by moving rfkill_unregister() and rfkill_destroy() outside thedevice_lock critical section. Store the rfkill pointer in a local variablebefore releasing the lock, then call rfkill_unregister() after releasingdevice_lock.This change is safe because rfkill_fop_write() holds rfkill_global_mutexwhile calling the rfkill callbacks, and rfkill_unregister() also acquiresrfkill_global_mutex before cleanup. Therefore, rfkill_unregister() willwait for any ongoing callback to complete before proceeding, anddevice_del() is only called after rfkill_unregister() returns, preventingany use-after-free.The similar lock ordering in nfc_register_device() (device_lock ->rfkill_global_mutex via rfkill_register) is safe because duringregistration the device is not yet in rfkill_list, so no concurrentrfkill operations can occur on this device.

CVE-2025-71080 Severity: Low CVSS3 score: 3.6

Description: In the Linux kernel, the following vulnerability has been resolved:ipv6: fix a BUG in rt6_get_pcpu_route() under PREEMPT_RTOn PREEMPT_RT kernels, after rt6_get_pcpu_route() returns NULL, thecurrent task can be preempted. Another task running on the same CPUmay then execute rt6_make_pcpu_route() and successfully install apcpu_rt entry. When the first task resumes execution, its cmpxchg()in rt6_make_pcpu_route() will fail because rt6i_pcpu is no longerNULL, triggering the BUG_ON(prev). It's easy to reproduce it by addingmdelay() after rt6_get_pcpu_route().Using preempt_disable/enable is not appropriate here becauseip6_rt_pcpu_alloc() may sleep.Fix this by handling the cmpxchg() failure gracefully on PREEMPT_RT:free our allocation and return the existing pcpu_rt installed byanother task. The BUG_ON is replaced by WARN_ON_ONCE for non-PREEMPT_RTkernels where such races should not occur.

CVE-2025-38549 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:efivarfs: Fix memory leak of efivarfs_fs_info in fs_context error pathsWhen processing mount options, efivarfs allocates efivarfs_fs_info (sfi)early in fs_context initialization. However, sfi is associated with thesuperblock and typically freed when the superblock is destroyed. If thefs_context is released (final put) before fill_super is called-such ason error paths or during reconfiguration-the sfi structure would leak,as ownership never transfers to the superblock.Implement the .free callback in efivarfs_context_ops to ensure anyallocated sfi is properly freed if the fs_context is torn down beforefill_super, preventing this memory leak.

CVE-2025-69652 Severity: Low CVSS3 score: 3.3

Description: GNU Binutils thru 2.46 readelf contains a vulnerability that leads to an abort (SIGABRT) when processing a crafted ELF binary with malformed DWARF abbrev or debug information. Due to incomplete state cleanup in process_debug_info(), an invalid debug_info_p state may propagate into DWARF attribute parsing routines. When certain malformed attributes result in an unexpected data length of zero, byte_get_little_endian() triggers a fatal abort. No evidence of memory corruption or code execution was observed; the impact is limited to denial of service.

But there are cases where we could avoid revalidation.Consider:1 input -> j2 -> j32 input -> j2 -> j33 input -> j1 -> j2 -> j3Then the second rule does not need to revalidate j2, and, by extension j3,because this was already checked during validation of the first rule.We need to validate it only for rule 3.This is needed because chain loop detection also ensures we do not exceedthe jump stack: Just because we know that j2 is cycle free, its last jumpmight now exceed the allowed stack size. We also need to update allreachable chains with the new largest observed call depth.Care has to be taken to revalidate even if the chain depth won't be anissue: chain validation also ensures that expressions are not called frominvalid base chains. For example, the masquerade expression can only becalled from NAT postrouting base chains.Therefore we also need to keep record of the base chain context (type,hooknum) and revalidate if the chain becomes reachable from a differenthook location.

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.

CVE-2025-39737 Severity: Low CVSS3 score: 2.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm/kmemleak: avoid soft lockup in __kmemleak_do_cleanup()A soft lockup warning was observed on a relative small system x86-64system with 16 GB of memory when running a debug kernel with kmemleakenabled. watchdog: BUG: soft lockup - CPU#8 stuck for 33s! [kworker/8:1:134]The test system was running a workload with hot unplug happening inparallel. Then kemleak decided to disable itself due to its inability toallocate more kmemleak objects. The debug kernel has itsCONFIG_DEBUG_KMEMLEAK_MEM_POOL_SIZE set to 40,000.The soft lockup happened in kmemleak_do_cleanup() when the existingkmemleak objects were being removed and deleted one-by-one in a loop via aworkqueue. In this particular case, there are at least 40,000 objectsthat need to be processed and given the slowness of a debug kernel and thefact that a raw_spinlock has to be acquired and released in__delete_object(), it could take a while to properly handle all theseobjects.As kmemleak has been disabled in this case, the object removal anddeletion process can be further optimized as locking isn't really needed. However, it is probably not worth the effort to optimize for such an edgecase that should rarely happen. So the simple solution is to callcond_resched() at periodic interval in the iteration loop to avoid softlockup.
