CVE-2026-43011 Severity: Critical CVSS3 score: 9.8

Description: In the Linux kernel, the following vulnerability has been resolved:net/x25: Fix potential double free of skbWhen alloc_skb fails in x25_queue_rx_frame it calls kfree_skb(skb) atline 48 and returns 1 (error).This error propagates back through the call chain:x25_queue_rx_frame returns 1 | vx25_state3_machine receives the return value 1 and takes the elsebranch at line 278, setting queued=0 and returning 0 | vx25_process_rx_frame returns queued=0 | vx25_backlog_rcv at line 452 sees queued=0 and calls kfree_skb(skb)againThis would free the same skb twice. Looking at x25_backlog_rcv:net/x25/x25_in.c:x25_backlog_rcv() { ... queued = x25_process_rx_frame(sk, skb); ... if (!queued) kfree_skb(skb);}

CVE-2024-12087 Severity: Important CVSS3 score: 8.8

Description: A path traversal vulnerability exists in rsync. It stems from behavior enabled by the `--inc-recursive` option, a default-enabled option for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the `--inc-recursive` option, a lack of proper symlink verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to write files outside of the client's intended destination directory. A malicious server could write malicious files to arbitrary locations named after valid directories/paths on the client.

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-2026-31622 Severity: Important CVSS3 score: 8.8

Description: In the Linux kernel, the following vulnerability has been resolved:NFC: digital: Bounds check NFC-A cascade depth in SDD response handlerThe NFC-A anti-collision cascade in digital_in_recv_sdd_res() appends 3or 4 bytes to target->nfcid1 on each round, but the number of cascaderounds is controlled entirely by the peer device. The peer sets thecascade tag in the SDD_RES (deciding 3 vs 4 bytes) and thecascade-incomplete bit in the SEL_RES (deciding whether another roundfollows).ISO 14443-3 limits NFC-A to three cascade levels and target->nfcid1 issized accordingly (NFC_NFCID1_MAXSIZE = 10), but nothing in the driveractually enforces this. This means a malicious peer can keep thecascade running, writing past the heap-allocated nfc_target with eachround.Fix this by rejecting the response when the accumulated UID would exceedthe buffer.Commit e329e71013c9 ("NFC: nci: Bounds check struct nfc_target arrays")fixed similar missing checks against the same field on the NCI path.

Description: In the Linux kernel, the following vulnerability has been resolved:nfc: llcp: add missing return after LLCP_CLOSED checksIn nfc_llcp_recv_hdlc() and nfc_llcp_recv_disc(), when the socketstate is LLCP_CLOSED, the code correctly calls release_sock() andnfc_llcp_sock_put() but fails to return. Execution falls through tothe remainder of the function, which calls release_sock() andnfc_llcp_sock_put() again. This results in a double release_sock()and a refcount underflow via double nfc_llcp_sock_put(), leading toa use-after-free.Add the missing return statements after the LLCP_CLOSED branchesin both functions to prevent the fall-through.

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: validate the whole DACL before rewriting it in cifsaclbuild_sec_desc() and id_mode_to_cifs_acl() derive a DACL pointer from aserver-supplied dacloffset and then use the incoming ACL to rebuild thechmod/chown security descriptor.The original fix only checked that the struct smb_acl header fits beforereading dacl_ptr->size or dacl_ptr->num_aces. That avoids the immediateheader-field OOB read, but the rewrite helpers still walk ACEs based onpdacl->num_aces with no structural validation of the incoming DACL body.A malicious server can return a truncated DACL that still contains aheader, claims one or more ACEs, and then drivereplace_sids_and_copy_aces() or set_chmod_dacl() past the validatedextent while they compare or copy attacker-controlled ACEs.Factor the DACL structural checks into validate_dacl(), extend them tovalidate each ACE against the DACL bounds, and use the shared validatorbefore the chmod/chown rebuild paths. parse_dacl() reuses the samevalidator so the read-side parser and write-side rewrite paths agree onwhat constitutes a well-formed incoming DACL.

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

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

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

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

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

CVE-2024-56326 Severity: Important CVSS3 score: 8.1

Description: Jinja is an extensible templating engine. Prior to 3.1.5, An oversight in how the Jinja sandboxed environment detects calls to str.format allows an attacker that controls the content of a template to execute arbitrary Python code. To exploit the vulnerability, an attacker needs to control the content of a template. Whether that is the case depends on the type of application using Jinja. This vulnerability impacts users of applications which execute untrusted templates. Jinja's sandbox does catch calls to str.format and ensures they don't escape the sandbox. However, it's possible to store a reference to a malicious string's format method, then pass that to a filter that calls it. No such filters are built-in to Jinja, but could be present through custom filters in an application. After the fix, such indirect calls are also handled by the sandbox. This vulnerability is fixed in 3.1.5.

CVE-2026-31708 Severity: Important CVSS3 score: 8.1

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: fix OOB read in smb2_ioctl_query_info QUERY_INFO pathsmb2_ioctl_query_info() has two response-copy branches: PASSTHRU_FSCTLand the default QUERY_INFO path. The QUERY_INFO branch clampsqi.input_buffer_length to the server-reported OutputBufferLength and thencopies qi.input_buffer_length bytes from qi_rsp->Buffer to userspace, butit never verifies that the flexible-array payload actually fits withinrsp_iov[1].iov_len.A malicious server can return OutputBufferLength larger than the actualQUERY_INFO response, causing copy_to_user() to walk past the responsebuffer and expose adjacent kernel heap to userspace.Guard the QUERY_INFO copy with a bounds check on the actual Bufferpayload. Use struct_size(qi_rsp, Buffer, qi.input_buffer_length)rather than an open-coded addition so the guard cannot overflow on32-bit builds.

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: hci_event: move wake reason storage into validated event handlershci_store_wake_reason() is called from hci_event_packet() immediatelyafter stripping the HCI event header but before hci_event_func()enforces the per-event minimum payload length from hci_ev_table.This means a short HCI event frame can reach bacpy() before any boundscheck runs.Rather than duplicating skb parsing and per-event length checks insidehci_store_wake_reason(), move wake-address storage into the individualevent handlers after their existing event-length validation hassucceeded. Convert hci_store_wake_reason() into a small helper that onlystores an already-validated bdaddr while the caller holds hci_dev_lock().Use the same helper after hci_event_func() with a NULL address topreserve the existing unexpected-wake fallback semantics when novalidated event handler records a wake address.Annotate the helper with __must_hold(&hdev->lock) and addlockdep_assert_held(&hdev->lock) so future call paths keep the lockcontract explicit.Call the helper from hci_conn_request_evt(), hci_conn_complete_evt(),hci_sync_conn_complete_evt(), le_conn_complete_evt(),hci_le_adv_report_evt(), hci_le_ext_adv_report_evt(),hci_le_direct_adv_report_evt(), hci_le_pa_sync_established_evt(), andhci_le_past_received_evt().

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-2026-41316 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.

Therefore, the range checkfor ip should be done later, but this part is missing and it seems that thevulnerability occurs.So we should add missing range checks and remove unnecessary range checks.

When the network namespace is deleted, the net structureaccessed by tcp's timer handler function causes problems.To fix this problem, let's hold netns refcnt for the tcp kernel socket asdone in other modules. This is an ugly hack which can easily be backportedto earlier kernels. A proper fix which cleans up the interfaces willfollow, but may not be so easy to backport.

CVE-2024-53214 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:vfio/pci: Properly hide first-in-list PCIe extended capabilityThere are cases where a PCIe extended capability should be hidden fromthe user. For example, an unknown capability (i.e., capability with IDgreater than PCI_EXT_CAP_ID_MAX) or a capability that is intentionallychosen to be hidden from the user.Hiding a capability is done by virtualizing and modifying the 'NextCapability Offset' field of the previous capability so it points to thecapability after the one that should be hidden.The special case where the first capability in the list should be hiddenis handled differently because there is no previous capability that canbe modified. In this case, the capability ID and version are zeroedwhile leaving the next pointer intact. This hides the capability andleaves an anchor for the rest of the capability list.However, today, hiding the first capability in the list is not doneproperly if the capability is unknown, as structvfio_pci_core_device->pci_config_map is set to the capability ID duringinitialization but the capability ID is not properly checked later whenused in vfio_config_do_rw(). This leads to the following warning [1] andto an out-of-bounds access to ecap_perms array.Fix it by checking cap_id in vfio_config_do_rw(), and if it is greaterthan PCI_EXT_CAP_ID_MAX, use an alternative struct perm_bits for directread only access instead of the ecap_perms array.Note that this is safe since the above is the only case where cap_id canexceed PCI_EXT_CAP_ID_MAX (except for the special capabilities, whichare already checked before).[1]WARNING: CPU: 118 PID: 5329 at drivers/vfio/pci/vfio_pci_config.c:1900 vfio_pci_config_rw+0x395/0x430 [vfio_pci_core]CPU: 118 UID: 0 PID: 5329 Comm: simx-qemu-syste Not tainted 6.12.0+ #1(snip)Call Trace: ? show_regs+0x69/0x80 ? __warn+0x8d/0x140 ? vfio_pci_config_rw+0x395/0x430 [vfio_pci_core] ? report_bug+0x18f/0x1a0 ? handle_bug+0x63/0xa0 ? exc_invalid_op+0x19/0x70 ? asm_exc_invalid_op+0x1b/0x20 ? vfio_pci_config_rw+0x395/0x430 [vfio_pci_core] ? vfio_pci_config_rw+0x244/0x430 [vfio_pci_core] vfio_pci_rw+0x101/0x1b0 [vfio_pci_core] vfio_pci_core_read+0x1d/0x30 [vfio_pci_core] vfio_device_fops_read+0x27/0x40 [vfio] vfs_read+0xbd/0x340 ? vfio_device_fops_unl_ioctl+0xbb/0x740 [vfio] ? __rseq_handle_notify_resume+0xa4/0x4b0 __x64_sys_pread64+0x96/0xc0 x64_sys_call+0x1c3d/0x20d0 do_syscall_64+0x4d/0x120 entry_SYSCALL_64_after_hwframe+0x76/0x7e

CVE-2024-56619 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: fix potential out-of-bounds memory access in nilfs_find_entry()Syzbot reported that when searching for records in a directory where theinode's i_size is corrupted and has a large value, memory access outsidethe folio/page range may occur, or a use-after-free bug may be detected ifKASAN is enabled.This is because nilfs_last_byte(), which is called by nilfs_find_entry()and others to calculate the number of valid bytes of directory data in apage from i_size and the page index, loses the upper 32 bits of the 64-bitsize information due to an inappropriate type of local variable to whichthe i_size value is assigned.This caused a large byte offset value due to underflow in the end addresscalculation in the calling nilfs_find_entry(), resulting in memory accessthat exceeds the folio/page size.Fix this issue by changing the type of the local variable causing the bitloss from "unsigned int" to "u64". The return value of nilfs_last_byte()is also of type "unsigned int", but it is truncated so as not to exceedPAGE_SIZE and no bit loss occurs, so no change is required.

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: In the Linux kernel, the following vulnerability has been resolved:fuse: reject oversized dirents in page cachefuse_add_dirent_to_cache() computes a serialized dirent size from theserver-controlled namelen field and copies the dirent into a singlepage-cache page. The existing logic only checks whether the dirent fitsin the remaining space of the current page and advances to a fresh pageif not. It never checks whether the dirent itself exceeds PAGE_SIZE.As a result, a malicious FUSE server can return a dirent withnamelen=4095, producing a serialized record size of 4120 bytes.

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

Once wrapped,tipc_group_bc_cong() keeps reporting congestion and later groupbroadcasts on the affected socket stay blocked until the group isrecreated.Fix this by ignoring duplicate or stale ACKs before touching bc_acked orbc_ackers.

CVE-2026-34986 Severity: Important CVSS3 score: 7.5

Description: Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption (JWE), JSON Web Signature (JWS), and JSON Web Token (JWT) standards. 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)`.

CVE-2026-31613 Severity: Important CVSS3 score: 7.1

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.

CVE-2026-31617 Severity: Important CVSS3 score: 7.1

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: f_ncm: validate minimum block_len in ncm_unwrap_ntb()The block_len read from the host-supplied NTB header is checked againstntb_max but has no lower bound. When block_len is smaller thanopts->ndp_size, the bounds check of: ndp_index > (block_len - opts->ndp_size)will underflow producing a huge unsigned value that ndp_index can neverexceed, defeating the check entirely.The same underflow occurs in the datagram index checks against block_len- opts->dpe_size. With those checks neutered, a malicious USB host canchoose ndp_index and datagram offsets that point past the actualtransfer, and the skb_put_data() copies adjacent kernel memory into thenetwork skb.Fix this by rejecting block lengths that cannot hold at least the NTBheader plus one NDP. This will make block_len - opts->ndp_size andblock_len - opts->dpe_size both well-defined.Commit 8d2b1a1ec9f5 ("CDC-NCM: avoid overflow in sanity checking") fixeda related class of issues on the host side of NCM.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: sg: Fix slab-use-after-free read in sg_release()Fix a use-after-free bug in sg_release(), detected by syzbot with KASAN:BUG: KASAN: slab-use-after-free in lock_release+0x151/0xa30kernel/locking/lockdep.c:5838__mutex_unlock_slowpath+0xe2/0x750 kernel/locking/mutex.c:912sg_release+0x1f4/0x2e0 drivers/scsi/sg.c:407In sg_release(), the function kref_put(&sfp->f_ref, sg_remove_sfp) iscalled before releasing the open_rel_lock mutex. The kref_put() call maydecrement the reference count of sfp to zero, triggering its cleanupthrough sg_remove_sfp(). This cleanup includes scheduling deferred workvia sg_remove_sfp_usercontext(), which ultimately frees sfp.After kref_put(), sg_release() continues to unlock open_rel_lock and mayreference sfp or sdp. If sfp has already been freed, this results in aslab-use-after-free error.Move the kref_put(&sfp->f_ref, sg_remove_sfp) call after unlocking theopen_rel_lock mutex. This ensures: - No references to sfp or sdp occur after the reference count is decremented. - Cleanup functions such as sg_remove_sfp() and sg_remove_sfp_usercontext() can safely execute without impacting the mutex handling in sg_release().The fix has been tested and validated by syzbot. This patch closes thebug reported at the following syzkaller link and ensures propersequencing of resource cleanup and mutex operations, eliminating therisk of use-after-free errors in sg_release().

CVE-2024-56759 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix use-after-free when COWing tree bock and tracing is enabledWhen a COWing a tree block, at btrfs_cow_block(), and we have thetracepoint trace_btrfs_cow_block() enabled and preemption is also enabled(CONFIG_PREEMPT=y), we can trigger a use-after-free in the COWed extentbuffer while inside the tracepoint code. This is because in some pathsthat call btrfs_cow_block(), such as btrfs_search_slot(), we are holdingthe last reference on the extent buffer @buf so btrfs_force_cow_block()drops the last reference on the @buf extent buffer when it callsfree_extent_buffer_stale(buf), which schedules the release of the extentbuffer with RCU. This means that if we are on a kernel with preemption,the current task may be preempted before calling trace_btrfs_cow_block()and the extent buffer already released by the time trace_btrfs_cow_block()is called, resulting in a use-after-free.Fix this by moving the trace_btrfs_cow_block() from btrfs_cow_block() tobtrfs_force_cow_block() before the COWed extent buffer is freed.This also has a side effect of invoking the tracepoint in the tree defragcode, at defrag.c:btrfs_realloc_node(), since btrfs_force_cow_block() iscalled there, but this is fine and it was actually missing there.

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. The discussion can be found atthe link below.Enable SVA on x86 architecture since the IOMMU can now receivenotification to flush the paging cache before freeing the CPU kernel pagetable pages.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nf_tables: fix use-after-free in nf_tables_addchain()nf_tables_addchain() publishes the chain to table->chains vialist_add_tail_rcu() (in nft_chain_add()) before registering hooks.If nf_tables_register_hook() then fails, the error path callsnft_chain_del() (list_del_rcu()) followed by nf_tables_chain_destroy()with no RCU grace period in between.This creates two use-after-free conditions: 1) Control-plane: nf_tables_dump_chains() traverses table->chains under rcu_read_lock(). A concurrent dump can still be walking the chain when the error path frees it. 2) Packet path: for NFPROTO_INET, nf_register_net_hook() briefly installs the IPv4 hook before IPv6 registration fails. Packets entering nft_do_chain() via the transient IPv4 hook can still be dereferencing chain->blob_gen_X when the error path frees the chain.Add synchronize_rcu() between nft_chain_del() and the chain destroyso that all RCU readers -- both dump threads and in-flight packetevaluation -- have finished before the chain is freed.

CVE-2026-23248 Severity: Important CVSS3 score: 7.0

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.

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.

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

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

CVE-2026-31419 Severity: Important CVSS3 score: 7.0

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

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-2026-31533 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.

CVE-2026-31588 Severity: Important CVSS3 score: 7.0

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.

CVE-2026-31669 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:mptcp: fix slab-use-after-free in __inet_lookup_establishedThe ehash table lookups are lockless and rely onSLAB_TYPESAFE_BY_RCU to guarantee socket memory stabilityduring RCU read-side critical sections. 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.

CVE-2026-31700 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:net/packet: fix TOCTOU race on mmap'd vnet_hdr in tpacket_snd()In tpacket_snd(), when PACKET_VNET_HDR is enabled, vnet_hdr pointsdirectly into the mmap'd TX ring buffer shared with userspace. Thekernel validates the header via __packet_snd_vnet_parse() but thenre-reads all fields later in virtio_net_hdr_to_skb(). A concurrentuserspace thread can modify the vnet_hdr fields between validationand use, bypassing all safety checks.The non-TPACKET path (packet_snd()) already correctly copies vnet_hdrto a stack-local variable. All other vnet_hdr consumers in the kernel(tun.c, tap.c, virtio_net.c) also use stack copies. The TPACKET TXpath is the only caller of virtio_net_hdr_to_skb() that reads directlyfrom user-controlled shared memory.Fix this by copying vnet_hdr from the mmap'd ring buffer to astack-local variable before validation and use, consistent with theapproach used in packet_snd() and all other callers.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: f_ecm: Fix net_device lifecycle with device_moveThe net_device is allocated during function instance creation andregistered during the bind phase with the gadget device as its sysfsparent. When the function unbinds, the parent device is destroyed, butthe net_device survives, resulting in dangling sysfs symlinks: console:/ # ls -l /sys/class/net/usb0 lrwxrwxrwx ... /sys/class/net/usb0 -> /sys/devices/platform/.../gadget.0/net/usb0 console:/ # ls -l /sys/devices/platform/.../gadget.0/net/usb0 ls: .../gadget.0/net/usb0: No such file or directoryUse device_move() to reparent the net_device between the gadget devicetree and /sys/devices/virtual across bind and unbind cycles. During thefinal unbind, calling device_move(NULL) moves the net_device to thevirtual device tree before the gadget device is destroyed. On rebinding,device_move() reparents the device back under the new gadget, ensuringproper sysfs topology and power management ordering.To maintain compatibility with legacy composite drivers (e.g., multi.c),the bound flag is used to indicate whether the network device is sharedand pre-registered during the legacy driver's bind phase.

CVE-2026-43050 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:atm: lec: fix use-after-free in sock_def_readable()A race condition exists between lec_atm_close() setting priv->lecdto NULL and concurrent access to priv->lecd in send_to_lecd(),lec_handle_bridge(), and lec_atm_send(). When the socket is freedvia RCU while another thread is still using it, a use-after-freeoccurs in sock_def_readable() when accessing the socket's wait queue.The root cause is that lec_atm_close() clears priv->lecd withoutany synchronization, while callers dereference priv->lecd withoutany protection against concurrent teardown.Fix this by converting priv->lecd to an RCU-protected pointer:- Mark priv->lecd as __rcu in lec.h- Use rcu_assign_pointer() in lec_atm_close() and lecd_attach() for safe pointer assignment- Use rcu_access_pointer() for NULL checks that do not dereference the pointer in lec_start_xmit(), lec_push(), send_to_lecd() and lecd_attach()- Use rcu_read_lock/rcu_dereference/rcu_read_unlock in send_to_lecd(), lec_handle_bridge() and lec_atm_send() to safely access lecd- Use rcu_assign_pointer() followed by synchronize_rcu() in lec_atm_close() to ensure all readers have completed before proceeding. This is safe since lec_atm_close() is called from vcc_release() which holds lock_sock(), a sleeping lock.- Remove the manual sk_receive_queue drain from lec_atm_close() since vcc_destroy_socket() already drains it after lec_atm_close() returns.v2: Switch from spinlock + sock_hold/put approach to RCU to properly fix the race. The v1 spinlock approach had two issues pointed out by Eric Dumazet: 1. priv->lecd was still accessed directly after releasing the lock instead of using a local copy. 2. The spinlock did not prevent packets being queued after lec_atm_close() drains sk_receive_queue since timer and workqueue paths bypass netif_stop_queue().Note: Syzbot patch testing was attempted but the test VM terminated unexpectedly with "Connection to localhost closed by remote host", likely due to a QEMU AHCI emulation issue unrelated to this fix. Compile testing with "make W=1 net/atm/lec.o" passes cleanly.

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

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

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

CVE-2026-31649 Severity: Moderate CVSS3 score: 6.8

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

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

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

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

CVE-2024-50164 Severity: Moderate CVSS3 score: 6.7

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix overloading of MEM_UNINIT's meaningLonial reported an issue in the BPF verifier where check_mem_size_reg()has the following code: if (!tnum_is_const(reg->var_off)) /* For unprivileged variable accesses, disable raw * mode so that the program is required to * initialize all the memory that the helper could * just partially fill up. */ meta = NULL;This means that writes are not checked when the register containing thesize of the passed buffer has not a fixed size. Through this bug, a BPFprogram can write to a map which is marked as read-only, for example,.rodata global maps.The problem is that MEM_UNINIT's initial meaning that "the passed bufferto the BPF helper does not need to be initialized" which was added backin commit 435faee1aae9 ("bpf, verifier: add ARG_PTR_TO_RAW_STACK type")got overloaded over time with "the passed buffer is being written to".The problem however is that checks such as the above which were added latervia 06c1c049721a ("bpf: allow helpers access to variable memory") set metato NULL in order force the user to always initialize the passed buffer tothe helper. Due to the current double meaning of MEM_UNINIT, this bypassesverifier write checks to the memory (not boundary checks though) and onlyassumes the latter memory is read instead.Fix this by reverting MEM_UNINIT back to its original meaning, and havingMEM_WRITE as an annotation to BPF helpers in order to then trigger theBPF verifier checks for writing to memory.Some notes: check_arg_pair_ok() ensures that for ARG_CONST_SIZE{,_OR_ZERO}we can access fn->arg_type[arg - 1] since it must contain a precedingARG_PTR_TO_MEM. For check_mem_reg() the meta argument can be removedaltogether since we do check both BPF_READ and BPF_WRITE. Same for theequivalent check_kfunc_mem_size_reg().

But the VMA address in the VAS window is not updatedwith munmap() which is causing invalid access during migration.The KASAN report shows:[16386.254991] BUG: KASAN: slab-use-after-free in reconfig_close_windows+0x1a0/0x4e8[16386.255043] Read of size 8 at addr c00000014a819670 by task drmgr/696928[16386.255096] CPU: 29 UID: 0 PID: 696928 Comm: drmgr Kdump: loaded Tainted: G B 6.11.0-rc5-nxgzip #2[16386.255128] Tainted: [B]=BAD_PAGE[16386.255148] Hardware name: IBM,9080-HEX Power11 (architected) 0x820200 0xf000007 of:IBM,FW1110.00 (NH1110_016) hv:phyp pSeries[16386.255181] Call Trace:[16386.255202] [c00000016b297660] [c0000000018ad0ac] dump_stack_lvl+0x84/0xe8 (unreliable)[16386.255246] [c00000016b297690] [c0000000006e8a90] print_report+0x19c/0x764[16386.255285] [c00000016b297760] [c0000000006e9490] kasan_report+0x128/0x1f8[16386.255309] [c00000016b297880] [c0000000006eb5c8] __asan_load8+0xac/0xe0[16386.255326] [c00000016b2978a0] [c00000000013f898] reconfig_close_windows+0x1a0/0x4e8[16386.255343] [c00000016b297990] [c000000000140e58] vas_migration_handler+0x3a4/0x3fc[16386.255368] [c00000016b297a90] [c000000000128848] pseries_migrate_partition+0x4c/0x4c4...[16386.256136] Allocated by task 696554 on cpu 31 at 16377.277618s:[16386.256149] kasan_save_stack+0x34/0x68[16386.256163] kasan_save_track+0x34/0x80[16386.256175] kasan_save_alloc_info+0x58/0x74[16386.256196] __kasan_slab_alloc+0xb8/0xdc[16386.256209] kmem_cache_alloc_noprof+0x200/0x3d0[16386.256225] vm_area_alloc+0x44/0x150[16386.256245] mmap_region+0x214/0x10c4[16386.256265] do_mmap+0x5fc/0x750[16386.256277] vm_mmap_pgoff+0x14c/0x24c[16386.256292] ksys_mmap_pgoff+0x20c/0x348[16386.256303] sys_mmap+0xd0/0x160...[16386.256350] Freed by task 0 on cpu 31 at 16386.204848s:[16386.256363] kasan_save_stack+0x34/0x68[16386.256374] kasan_save_track+0x34/0x80[16386.256384] kasan_save_free_info+0x64/0x10c[16386.256396] __kasan_slab_free+0x120/0x204[16386.256415] kmem_cache_free+0x128/0x450[16386.256428] vm_area_free_rcu_cb+0xa8/0xd8[16386.256441] rcu_do_batch+0x2c8/0xcf0[16386.256458] rcu_core+0x378/0x3c4[16386.256473] handle_softirqs+0x20c/0x60c[16386.256495] do_softirq_own_stack+0x6c/0x88[16386.256509] do_softirq_own_stack+0x58/0x88[16386.256521] __irq_exit_rcu+0x1a4/0x20c[16386.256533] irq_exit+0x20/0x38[16386.256544] interrupt_async_exit_prepare.constprop.0+0x18/0x2c...[16386.256717] Last potentially related work creation:[16386.256729] kasan_save_stack+0x34/0x68[16386.256741] __kasan_record_aux_stack+0xcc/0x12c[16386.256753] __call_rcu_common.constprop.0+0x94/0xd04[16386.256766] vm_area_free+0x28/0x3c[16386.256778] remove_vma+0xf4/0x114[16386.256797] do_vmi_align_munmap.constprop.0+0x684/0x870[16386.256811] __vm_munmap+0xe0/0x1f8[16386.256821] sys_munmap+0x54/0x6c[16386.256830] system_call_exception+0x1a0/0x4a0[16386.256841] system_call_vectored_common+0x15c/0x2ec[16386.256868] The buggy address belongs to the object at c00000014a819670 which belongs to the cache vm_area_struct of size 168[16386.256887] The buggy address is located 0 bytes inside of freed 168-byte region [c00000014a819670, c00000014a819718)[16386.256915] The buggy address belongs to the physical page:[16386.256928] page: refcount:1 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x14a81[16386.256950] memcg:c0000000ba430001[16386.256961] anon flags: 0x43ffff800000000(node=4|zone=0|lastcpupid=0x7ffff)[16386.256975] page_type: 0xfdffffff(slab)[16386---truncated---

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

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: ufs: core: Fix use-after free in init error and remove pathsdevm_blk_crypto_profile_init() registers a cleanup handler to run whenthe associated (platform-) device is being released. For UFS, thecrypto private data and pointers are stored as part of the ufs_hba'sdata structure 'struct ufs_hba::crypto_profile'. This structure isallocated as part of the underlying ufshcd and therefore Scsi_hostallocation.During driver release or during error handling in ufshcd_pltfrm_init(),this structure is released as part of ufshcd_dealloc_host() before the(platform-) device associated with the crypto call above is released.Once this device is released, the crypto cleanup code will run, usingthe just-released 'struct ufs_hba::crypto_profile'. This causes ause-after-free situation: Call trace: kfree+0x60/0x2d8 (P) kvfree+0x44/0x60 blk_crypto_profile_destroy_callback+0x28/0x70 devm_action_release+0x1c/0x30 release_nodes+0x6c/0x108 devres_release_all+0x98/0x100 device_unbind_cleanup+0x20/0x70 really_probe+0x218/0x2d0In other words, the initialisation code flow is: platform-device probe ufshcd_pltfrm_init() ufshcd_alloc_host() scsi_host_alloc() allocation of struct ufs_hba creation of scsi-host devices devm_blk_crypto_profile_init() devm registration of cleanup handler using platform-deviceand during error handling of ufshcd_pltfrm_init() or during driverremoval: ufshcd_dealloc_host() scsi_host_put() put_device(scsi-host) release of struct ufs_hba put_device(platform-device) crypto cleanup handlerTo fix this use-after free, change ufshcd_alloc_host() to register adevres action to automatically cleanup the underlying SCSI device onufshcd destruction, without requiring explicit calls toufshcd_dealloc_host(). This way: * the crypto profile and all other ufs_hba-owned resources are destroyed before SCSI (as they've been registered after) * a memleak is plugged in tc-dwc-g210-pci.c remove() as a side-effect * EXPORT_SYMBOL_GPL(ufshcd_dealloc_host) can be removed fully as it's not needed anymore * no future drivers using ufshcd_alloc_host() could ever forget adding the cleanup

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

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

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

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

CVE-2024-53150 Severity: Moderate CVSS3 score: 6.6

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

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

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

CVE-2025-38455 Severity: Moderate CVSS3 score: 6.6

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

Similarly the PCI rescan/remove lockwas also taken in sriov_add_vfs() to protect addition of VFs.This approach however causes deadlock on trying to remove PFs with SR-IOVenabled because PFs disable SR-IOV during removal and this removal happensunder the PCI rescan/remove lock.

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

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

CVE-2026-31426 Severity: Moderate CVSS3 score: 6.6

Description: In the Linux kernel, the following vulnerability has been resolved:ACPI: EC: clean up handlers on probe failure in acpi_ec_setup()When ec_install_handlers() returns -EPROBE_DEFER on reduced-hardwareplatforms, it has already started the EC and installed the addressspace handler with the struct acpi_ec pointer as handler context.However, acpi_ec_setup() propagates the error without any cleanup.The caller acpi_ec_add() then frees the struct acpi_ec for non-bootinstances, leaving a dangling handler context in ACPICA.Any subsequent AML evaluation that accesses an EC OpRegion fielddispatches into acpi_ec_space_handler() with the freed pointer,causing a use-after-free: BUG: KASAN: slab-use-after-free in mutex_lock (kernel/locking/mutex.c:289) Write of size 8 at addr ffff88800721de38 by task init/1 Call Trace: mutex_lock (kernel/locking/mutex.c:289) acpi_ec_space_handler (drivers/acpi/ec.c:1362) acpi_ev_address_space_dispatch (drivers/acpi/acpica/evregion.c:293) acpi_ex_access_region (drivers/acpi/acpica/exfldio.c:246) acpi_ex_field_datum_io (drivers/acpi/acpica/exfldio.c:509) acpi_ex_extract_from_field (drivers/acpi/acpica/exfldio.c:700) acpi_ex_read_data_from_field (drivers/acpi/acpica/exfield.c:327) acpi_ex_resolve_node_to_value (drivers/acpi/acpica/exresolv.c:392) Allocated by task 1: acpi_ec_alloc (drivers/acpi/ec.c:1424) acpi_ec_add (drivers/acpi/ec.c:1692) Freed by task 1: kfree (mm/slub.c:6876) acpi_ec_add (drivers/acpi/ec.c:1751)The bug triggers on reduced-hardware EC platforms (ec->gpe < 0)when the GPIO IRQ provider defers probing. Once the stale handlerexists, any unprivileged sysfs read that causes AML to touch anEC OpRegion (battery, thermal, backlight) exercises the danglingpointer.Fix this by calling ec_remove_handlers() in the error path ofacpi_ec_setup() before clearing first_ec. ec_remove_handlers()checks each EC_FLAGS_* bit before acting, so it is safe to callregardless of how far ec_install_handlers() progressed: -ENODEV (handler not installed): only calls acpi_ec_stop() -EPROBE_DEFER (handler installed): removes handler, stops EC

Description: Vim is an open source, command line text editor. Prior to 9.2.0357, A command injection vulnerability exists in Vim's tag file processing. When resolving a tag, the filename field from the tags file is passed through wildcard expansion to resolve environment variables and wildcards. If the filename field contains backtick syntax (e.g., `command`), Vim executes the embedded command via the system shell with the full privileges of the running user.

Description: In the Linux kernel, the following vulnerability has been resolved:media: vidtv: fix pass-by-value structs causing MSAN warningsvidtv_ts_null_write_into() and vidtv_ts_pcr_write_into() take theirargument structs by value, causing MSAN to report uninit-value warnings.While only vidtv_ts_null_write_into() has triggered a report so far,both functions share the same issue.Fix by passing both structs by const pointer instead, avoiding thestack copy of the struct along with its MSAN shadow and origin metadata.The functions do not modify the structs, which is enforced by the constqualifier.

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

Fix it by alsoremoving flow_block_cb instances from driver_list before deallocating them.[0]:[ 279.868433] ==================================================================[ 279.869964] BUG: KASAN: slab-use-after-free in flow_block_cb_setup_simple+0x631/0x7c0[ 279.871527] Read of size 8 at addr ffff888147e2bf20 by task tc/2963[ 279.873151] CPU: 6 PID: 2963 Comm: tc Not tainted 6.3.0-rc6+ #4[ 279.874273] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014[ 279.876295] Call Trace:[ 279.876882] [ 279.877413] dump_stack_lvl+0x33/0x50[ 279.878198] print_report+0xc2/0x610[ 279.878987] ? flow_block_cb_setup_simple+0x631/0x7c0[ 279.879994] kasan_report+0xae/0xe0[ 279.880750] ? flow_block_cb_setup_simple+0x631/0x7c0[ 279.881744] ? mlx5e_tc_reoffload_flows_work+0x240/0x240 [mlx5_core][ 279.883047] flow_block_cb_setup_simple+0x631/0x7c0[ 279.884027] tcf_block_offload_cmd.isra.0+0x189/0x2d0[ 279.885037] ? tcf_block_setup+0x6b0/0x6b0[ 279.885901] ? mutex_lock+0x7d/0xd0[ 279.886669] ? __mutex_unlock_slowpath.constprop.0+0x2d0/0x2d0[ 279.887844] ? ingress_init+0x1c0/0x1c0 [sch_ingress][ 279.888846] tcf_block_get_ext+0x61c/0x1200[ 279.889711] ingress_init+0x112/0x1c0 [sch_ingress][ 279.890682] ? clsact_init+0x2b0/0x2b0 [sch_ingress][ 279.891701] qdisc_create+0x401/0xea0[ 279.892485] ? qdisc_tree_reduce_backlog+0x470/0x470[ 279.893473] tc_modify_qdisc+0x6f7/0x16d0[ 279.894344] ? tc_get_qdisc+0xac0/0xac0[ 279.895213] ? mutex_lock+0x7d/0xd0[ 279.896005] ? __mutex_lock_slowpath+0x10/0x10[ 279.896910] rtnetlink_rcv_msg+0x5fe/0x9d0[ 279.897770] ? rtnl_calcit.isra.0+0x2b0/0x2b0[ 279.898672] ? __sys_sendmsg+0xb5/0x140[ 279.899494] ? do_syscall_64+0x3d/0x90[ 279.900302] ? entry_SYSCALL_64_after_hwframe+0x46/0xb0[ 279.901337] ? kasan_save_stack+0x2e/0x40[ 279.902177] ? kasan_save_stack+0x1e/0x40[ 279.903058] ? kasan_set_track+0x21/0x30[ 279.903913] ? kasan_save_free_info+0x2a/0x40[ 279.904836] ? ____kasan_slab_free+0x11a/0x1b0[ 279.905741] ? kmem_cache_free+0x179/0x400[ 279.906599] netlink_rcv_skb+0x12c/0x360[ 279.907450] ? rtnl_calcit.isra.0+0x2b0/0x2b0[ 279.908360] ? netlink_ack+0x1550/0x1550[ 279.909192] ? rhashtable_walk_peek+0x170/0x170[ 279.910135] ? kmem_cache_alloc_node+0x1af/0x390[ 279.911086] ? _copy_from_iter+0x3d6/0xc70[ 279.912031] netlink_unicast+0x553/0x790[ 279.912864] ? netlink_attachskb+0x6a0/0x6a0[ 279.913763] ? netlink_recvmsg+0x416/0xb50[ 279.914627] netlink_sendmsg+0x7a1/0xcb0[ 279.915473] ? netlink_unicast+0x790/0x790[ 279.916334] ? iovec_from_user.part.0+0x4d/0x220[ 279.917293] ? netlink_unicast+0x790/0x790[ 279.918159] sock_sendmsg+0xc5/0x190[ 279.918938] ____sys_sendmsg+0x535/0x6b0[ 279.919813] ? import_iovec+0x7/0x10[ 279.920601] ? kernel_sendmsg+0x30/0x30[ 279.921423] ? __copy_msghdr+0x3c0/0x3c0[ 279.922254] ? import_iovec+0x7/0x10[ 279.923041] ___sys_sendmsg+0xeb/0x170[ 279.923854] ? copy_msghdr_from_user+0x110/0x110[ 279.924797] ? ___sys_recvmsg+0xd9/0x130[ 279.925630] ? __perf_event_task_sched_in+0x183/0x470[ 279.926656] ? ___sys_sendmsg+0x170/0x170[ 279.927529] ? ctx_sched_in+0x530/0x530[ 279.928369] ? update_curr+0x283/0x4f0[ 279.929185] ? perf_event_update_userpage+0x570/0x570[ 279.930201] ? __fget_light+0x57/0x520[ 279.931023] ? __switch_to+0x53d/0xe70[ 27---truncated---

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

CVE-2024-12086 Severity: Moderate CVSS3 score: 6.5

Description: A flaw was found in rsync. It could allow a server to enumerate the contents of an arbitrary file from the client's machine. This issue occurs when files are being copied from a client to a server. During this process, the rsync server will send checksums of local data to the client to compare with in order to determine what data needs to be sent to the server. By sending specially constructed checksum values for arbitrary files, an attacker may be able to reconstruct the data of those files byte-by-byte based on the responses from the client.

CVE-2024-12088 Severity: Moderate CVSS3 score: 6.5

Description: A flaw was found in rsync. When using the `--safe-links` option, the rsync client fails to properly verify if a symbolic link destination sent from the server contains another symbolic link within it. This results in a path traversal vulnerability, which may lead to arbitrary file write outside the desired directory.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:can: kvaser_pciefd: refine error prone echo_skb_max handling logicecho_skb_max should define the supported upper limit of echo_skb[]allocated inside the netdevice's priv. 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. Kasan reported this forthe ack case inside kvaser_pciefd_handle_ack_packet(), though the xmitfunction has actually caught the same thing earlier.

The onlydownside is that the size of echo_skb[] should correspond to the max seqnumber (not tx max count), so in some situations a bit more memory wouldbe consumed than could be.Thus make the size of the underlying echo_skb[] sufficient for the roundedmax tx value.Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

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

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

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

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

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

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

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

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: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: L2CAP: Fix ERTM re-init and zero pdu_len infinite loopl2cap_config_req() processes CONFIG_REQ for channels in BT_CONNECTEDstate to support L2CAP reconfiguration (e.g. MTU changes). However,since both CONF_INPUT_DONE and CONF_OUTPUT_DONE are already set fromthe initial configuration, the reconfiguration path falls through tol2cap_ertm_init(), which re-initializes tx_q, srej_q, srej_list, andretrans_list without freeing the previous allocations and setschan->sdu to NULL without freeing the existing skb. This leaks allpreviously allocated ERTM resources.Additionally, l2cap_parse_conf_req() does not validate the minimumvalue of remote_mps derived from the RFC max_pdu_size option. A zerovalue propagates to l2cap_segment_sdu() where pdu_len becomes zero,causing the while loop to never terminate since len is neverdecremented, exhausting all available memory.Fix the double-init by skipping l2cap_ertm_init() andl2cap_chan_ready() when the channel is already in BT_CONNECTED state,while still allowing the reconfiguration parameters to be updatedthrough l2cap_parse_conf_req().

Description: In the Linux kernel, the following vulnerability has been resolved:usbip: validate number_of_packets in usbip_pack_ret_submit()When a USB/IP client receives a RET_SUBMIT response,usbip_pack_ret_submit() unconditionally overwritesurb->number_of_packets from the network PDU. This value issubsequently used as the loop bound in usbip_recv_iso() andusbip_pad_iso() to iterate over urb->iso_frame_desc[], a flexiblearray whose size was fixed at URB allocation time based on the*original* number_of_packets from the CMD_SUBMIT.A malicious USB/IP server can set number_of_packets in the responseto a value larger than what was originally submitted, causing a heapout-of-bounds write when usbip_recv_iso() writes tourb->iso_frame_desc[i] beyond the allocated region.KASAN confirmed this with kernel 7.0.0-rc5: BUG: KASAN: slab-out-of-bounds in usbip_recv_iso+0x46a/0x640 Write of size 4 at addr ffff888106351d40 by task vhci_rx/69 The buggy address is located 0 bytes to the right of allocated 320-byte region [ffff888106351c00, ffff888106351d40)The server side (stub_rx.c) and gadget side (vudc_rx.c) alreadyvalidate number_of_packets in the CMD_SUBMIT path since commitsc6688ef9f297 ("usbip: fix stub_rx: harden CMD_SUBMIT path to handlemalicious input") and b78d830f0049 ("usbip: fix vudc_rx: hardenCMD_SUBMIT path to handle malicious input"). The server side validatesagainst USBIP_MAX_ISO_PACKETS because no URB exists yet at that point.On the client side we have the original URB, so we can use the tighterbound: the response must not exceed the original number_of_packets.This mirrors the existing validation of actual_length againsttransfer_buffer_length in usbip_recv_xbuff(), which checks theresponse value against the original allocation size.Kelvin Mbogo's series ("usb: usbip: fix integer overflow inusbip_recv_iso()", v2) hardens the receive-side functions themselves;this patch complements that work by catching the bad value at itssource -- in usbip_pack_ret_submit() before the overwrite -- andusing the tighter per-URB allocation bound rather than the globalUSBIP_MAX_ISO_PACKETS limit.Fix this by checking rpdu->number_of_packets againsturb->number_of_packets in usbip_pack_ret_submit() before theoverwrite. On violation, clamp to zero so that usbip_recv_iso() andusbip_pad_iso() safely return early.

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.

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

Set fb1's mode to the global fb_display[] array (via FBIOPUT_CON2FBMAP);3. Switch console from fb to VGA (to allow normal rmmod of the ko);4. Unload the kernel module, at this point fb1's modelist is freed, leaving a wild pointer in fb_display[];5. Trigger the bug via system calls through fb0 attempting to delete a mode from fb0.Add a check in do_unregister_framebuffer(): if the mode to be freed existsin fb_display[], set the corresponding mode pointer to NULL.

Both functions will eventually schedule allremaining associations for deletion.The current implementation checks whether an association is about to beremoved, but only after the work item has already been scheduled. As aresult, it is possible for the first scheduled work item to free allresources, and then for the same work item to be scheduled again fordeletion.Because the association list is an RCU list, it is not possible to takea lock and remove the list entry directly, so it cannot be looked upagain. Instead, a flag (terminating) must be used to determine whetherthe association is already in the process of being deleted.

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

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

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

CVE-2026-31488 Severity: Moderate CVSS3 score: 6.4

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amd/display: Do not skip unrelated mode changes in DSC validationStarting with commit 17ce8a6907f7 ("drm/amd/display: Add dsc pre-validation inatomic check"), amdgpu resets the CRTC state mode_changed flag to false whenrecomputing the DSC configuration results in no timing change for a particularstream.However, this is incorrect in scenarios where a change in MST/DSC configurationhappens in the same KMS commit as another (unrelated) mode change. For example,the integrated panel of a laptop may be configured differently (e.g., HDRenabled/disabled) depending on whether external screens are attached. In thiscase, plugging in external DP-MST screens may result in the mode_changed flagbeing dropped incorrectly for the integrated panel if its DSC configurationdid not change during precomputation in pre_validate_dsc().At this point, however, dm_update_crtc_state() has already created new streamsfor CRTCs with DSC-independent mode changes. In turn,amdgpu_dm_commit_streams() will never release the old stream, resulting in amemory leak. amdgpu_dm_atomic_commit_tail() will never acquire a reference tothe new stream either, which manifests as a use-after-free when the stream getsdisabled later on:BUG: KASAN: use-after-free in dc_stream_release+0x25/0x90 [amdgpu]Write of size 4 at addr ffff88813d836524 by task kworker/9:9/29977Workqueue: events drm_mode_rmfb_work_fnCall Trace: dump_stack_lvl+0x6e/0xa0 print_address_description.constprop.0+0x88/0x320 ? dc_stream_release+0x25/0x90 [amdgpu] print_report+0xfc/0x1ff ? srso_alias_return_thunk+0x5/0xfbef5 ? __virt_addr_valid+0x225/0x4e0 ? dc_stream_release+0x25/0x90 [amdgpu] kasan_report+0xe1/0x180 ? dc_stream_release+0x25/0x90 [amdgpu] kasan_check_range+0x125/0x200 dc_stream_release+0x25/0x90 [amdgpu] dc_state_destruct+0x14d/0x5c0 [amdgpu] dc_state_release.part.0+0x4e/0x130 [amdgpu] dm_atomic_destroy_state+0x3f/0x70 [amdgpu] drm_atomic_state_default_clear+0x8ee/0xf30 ? drm_mode_object_put.part.0+0xb1/0x130 __drm_atomic_state_free+0x15c/0x2d0 atomic_remove_fb+0x67e/0x980Since there is no reliable way of figuring out whether a CRTC has unrelatedmode changes pending at the time of DSC validation, remember the value of themode_changed flag from before the point where a CRTC was marked as potentiallyaffected by a change in DSC configuration.

CVE-2026-31502 Severity: Moderate CVSS3 score: 6.4

Description: In the Linux kernel, the following vulnerability has been resolved:team: fix header_ops type confusion with non-Ethernet portsSimilar to commit 950803f72547 ("bonding: fix type confusion inbond_setup_by_slave()") team has the same class of header_ops typeconfusion.For non-Ethernet ports, team_setup_by_port() copies port_dev->header_opsdirectly. 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.

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-2022-50720 Severity: Moderate CVSS3 score: 6.3

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:mm/swap: fix swap_info_struct race between swapoff and get_swap_pages()The si->lock must be held when deleting the si from the available list. Otherwise, another thread can re-add the si to the available list, whichcan lead to memory corruption. The only place we have found where thishappens is in the swapoff path. This case can be described as below:core 0 core 1swapoffdel_from_avail_list(si) waitingtry lock si->lock acquire swap_avail_lock and re-add si into swap_avail_headacquire si->lock but missing si already being added again, and continuingto clear SWP_WRITEOK, etc.It can be easily found that a massive warning messages can be triggeredinside get_swap_pages() by some special cases, for example, we callmadvise(MADV_PAGEOUT) on blocks of touched memory concurrently, meanwhile,run much swapon-swapoff operations (e.g. stress-ng-swap).However, in the worst case, panic can be caused by the above scene. Inswapoff(), the memory used by si could be kept in swap_info[] afterturning off a swap. This means memory corruption will not be causedimmediately until allocated and reset for a new swap in the swapon path. A panic message caused: (with CONFIG_PLIST_DEBUG enabled)------------[ cut here ]------------top: 00000000e58a3003, n: 0000000013e75cda, p: 000000008cd4451aprev: 0000000035b1e58a, n: 000000008cd4451a, p: 000000002150ee8dnext: 000000008cd4451a, n: 000000008cd4451a, p: 000000008cd4451aWARNING: CPU: 21 PID: 1843 at lib/plist.c:60 plist_check_prev_next_node+0x50/0x70Modules linked in: rfkill(E) crct10dif_ce(E)...CPU: 21 PID: 1843 Comm: stress-ng Kdump: ... 5.10.134+Hardware name: Alibaba Cloud ECS, BIOS 0.0.0 02/06/2015pstate: 60400005 (nZCv daif +PAN -UAO -TCO BTYPE=--)pc : plist_check_prev_next_node+0x50/0x70lr : plist_check_prev_next_node+0x50/0x70sp : ffff0018009d3c30x29: ffff0018009d3c40 x28: ffff800011b32a98x27: 0000000000000000 x26: ffff001803908000x25: ffff8000128ea088 x24: ffff800011b32a48x23: 0000000000000028 x22: ffff001800875c00x21: ffff800010f9e520 x20: ffff001800875c00x19: ffff001800fdc6e0 x18: 0000000000000030x17: 0000000000000000 x16: 0000000000000000x15: 0736076307640766 x14: 0730073007380731x13: 0736076307640766 x12: 0730073007380731x11: 000000000004058d x10: 0000000085a85b76x9 : ffff8000101436e4 x8 : ffff800011c8ce08x7 : 0000000000000000 x6 : 0000000000000001x5 : ffff0017df9ed338 x4 : 0000000000000001x3 : ffff8017ce62a000 x2 : ffff0017df9ed340x1 : 0000000000000000 x0 : 0000000000000000Call trace: plist_check_prev_next_node+0x50/0x70 plist_check_head+0x80/0xf0 plist_add+0x28/0x140 add_to_avail_list+0x9c/0xf0 _enable_swap_info+0x78/0xb4 __do_sys_swapon+0x918/0xa10 __arm64_sys_swapon+0x20/0x30 el0_svc_common+0x8c/0x220 do_el0_svc+0x2c/0x90 el0_svc+0x1c/0x30 el0_sync_handler+0xa8/0xb0 el0_sync+0x148/0x180irq event stamp: 2082270Now, si->lock locked before calling 'del_from_avail_list()' to make sureother thread see the si had been deleted and SWP_WRITEOK cleared together,will not reinsert again.This problem exists in versions after stable 5.10.y.

CVE-2023-54324 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:dm: fix a race condition in retrieve_depsThere's a race condition in the multipath target when retrieve_depsraces with multipath_message calling dm_get_device and dm_put_device.retrieve_deps walks the list of open devices without holding any lockbut multipath may add or remove devices to the list while it isrunning. The end result may be memory corruption or use-after-freememory access.See this description of a UAF with multipath_message():https://listman.redhat.com/archives/dm-devel/2022-October/052373.htmlFix this bug by introducing a new rw semaphore "devices_lock". We grabdevices_lock for read in retrieve_deps and we grab it for write indm_get_device and dm_put_device.

CVE-2024-12747 Severity: Moderate CVSS3 score: 6.3

Description: A flaw was found in rsync. This vulnerability arises from a race condition during rsync's handling of symbolic links. Rsync's default behavior when encountering symbolic links is to skip them. If an attacker replaced a regular file with a symbolic link at the right time, it was possible to bypass the default behavior and traverse symbolic links. Depending on the privileges of the rsync process, an attacker could leak sensitive information, potentially leading to privilege escalation.

CVE-2024-42084 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:ftruncate: pass a signed offsetThe old ftruncate() syscall, using the 32-bit off_t misses a signextension when called in compat mode on 64-bit architectures. As aresult, passing a negative length accidentally succeeds in truncatingto file size between 2GiB and 4GiB.Changing the type of the compat syscall to the signed compat_off_tchanges the behavior so it instead returns -EINVAL.The native entry point, the truncate() syscall and the correspondingloff_t based variants are all correct already and do not sufferfrom this mistake.

Description: In the Linux kernel, the following vulnerability has been resolved:can: bcm: add locking for bcm_op runtime updatesThe CAN broadcast manager (CAN BCM) can send a sequence of CAN frames viahrtimer. The content and also the length of the sequence can be changedresp reduced at runtime where the 'currframe' counter is then set to zero.Although this appeared to be a safe operation the updates of 'currframe'can be triggered from user space and hrtimer context in bcm_can_tx().Anderson Nascimento created a proof of concept that triggered a KASANslab-out-of-bounds read access which can be prevented with a spin_lock_bh.At the rework of bcm_can_tx() the 'count' variable has been moved intothe protected section as this variable can be modified from both contextstoo.

Description: In the Linux kernel, the following vulnerability has been resolved:mm/page_alloc: fix race condition in unaccepted memory handlingThe page allocator tracks the number of zones that have unaccepted memoryusing static_branch_enc/dec() and uses that static branch in hot paths todetermine if it needs to deal with unaccepted memory.Borislav and Thomas pointed out that the tracking is racy: operations onstatic_branch are not serialized against adding/removing unaccepted pagesto/from the zone.Sanity checks inside static_branch machinery detects it:WARNING: CPU: 0 PID: 10 at kernel/jump_label.c:276 __static_key_slow_dec_cpuslocked+0x8e/0xa0The comment around the WARN() explains the problem: /* * Warn about the '-1' case though; since that means a * decrement is concurrent with a first (0->1) increment. IOW * people are trying to disable something that wasn't yet fully * enabled. This suggests an ordering problem on the user side. */The effect of this static_branch optimization is only visible onmicrobenchmark.Instead of adding more complexity around it, remove it altogether.

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

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

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

CVE-2025-40043 Severity: Moderate CVSS3 score: 6.3

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

Although ext4_get_max_inline_size() reads the correct value at thetime of the check, concurrent xattr operations can modify i_inline_sizebefore ext4_write_lock_xattr() is acquired.This causes ext4_update_inline_data() and ext4_create_inline_data() towork with stale capacity values, leading to a BUG_ON() crash inext4_write_inline_data(): kernel BUG at fs/ext4/inline.c:1331! BUG_ON(pos + len > EXT4_I(inode)->i_inline_size);The race window:1. ext4_get_max_inline_size() reads i_inline_size = 60 (correct)2. Size check passes for 50-byte write3. [Another thread adds xattr, i_inline_size changes to 40]4. ext4_write_lock_xattr() acquires lock5. ext4_update_inline_data() uses stale i_inline_size = 606.

This ensures ext4_update_inline_data()and ext4_create_inline_data() work with current values that are protectedfrom concurrent modifications.This is similar to commit a54c4613dac1 ("ext4: fix race writing to aninline_data file while its xattrs are changing") which fixed i_inline_offstaleness.

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

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

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

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

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

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

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

CVE-2023-53484 Severity: Moderate CVSS3 score: 6.2

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

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

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

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

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

CVE-2023-54259 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:soundwire: bus: Fix unbalanced pm_runtime_put() causing usage count underflowThis reverts commit443a98e649b4 ("soundwire: bus: use pm_runtime_resume_and_get()")Change calls to pm_runtime_resume_and_get() back to pm_runtime_get_sync().This fixes a usage count underrun caused by doing a pm_runtime_put() eventhough pm_runtime_resume_and_get() returned an error.The three affected functions ignore -EACCES error from trying to getpm_runtime, and carry on, including a put at the end of the function.But pm_runtime_resume_and_get() does not increment the usage count if itreturns an error. So in the -EACCES case you must not callpm_runtime_put().The documentation for pm_runtime_get_sync() says: "Consider using pm_runtime_resume_and_get() ... as this is likely to result in cleaner code."In this case I don't think it results in cleaner code because thepm_runtime_put() at the end of the function would have to be conditional onthe return value from pm_runtime_resume_and_get() at the top of thefunction.pm_runtime_get_sync() doesn't have this problem because it alwaysincrements the count, so always needs a put. The code can just flow throughand do the pm_runtime_put() unconditionally.

Although this init_waitqueue_head() call will very likelycomplete before this kthread is created and starts running, it ispossible that the calling kthread will be delayed between the calls totorture_create_kthread() and init_waitqueue_head().

Description: In the Linux kernel, the following vulnerability has been resolved:EDAC/bluefield: Fix potential integer overflowThe 64-bit argument for the "get DIMM info" SMC call consists of mem_ctrl_idxleft-shifted 16 bits and OR-ed with DIMM index. With mem_ctrl_idx defined as32-bits wide the left-shift operation truncates the upper 16 bits ofinformation during the calculation of the SMC argument.The mem_ctrl_idx stack variable must be defined as 64-bits wide to prevent anypotential integer overflow, i.e. loss of data from upper 16 bits.

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

Then it read the firstbyte of the first 2 bytes to determine the direction.The issue is that only the first byte indicating direction is initializedin current ppp driver code while the second byte is not initialized.For normal BPF programs generated by libpcap, uninitialized data won't beused, so it's not a problem.

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

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/iwcm: Fix use-after-free of work objects after cm_id destructionThe commit 59c68ac31e15 ("iw_cm: free cm_id resources on the lastderef") simplified cm_id resource management by freeing cm_id once allreferences to the cm_id were removed. The references are removed eitherupon completion of iw_cm event handlers or when the application destroysthe cm_id. This commit introduced the use-after-free condition wherecm_id_private object could still be in use by event handler works duringthe destruction of cm_id. The commit aee2424246f9 ("RDMA/iwcm: Fix ause-after-free related to destroying CM IDs") addressed this use-after-free by flushing all pending works at the cm_id destruction.However, still another use-after-free possibility remained.

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

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

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

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

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

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

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-2025-39923 Severity: Moderate CVSS3 score: 6.1

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:backlight: led-bl: Add devlink to supplier LEDsLED Backlight is a consumer of one or multiple LED class devices, butdevlink is currently unable to create correct supplier-producer links whenthe supplier is a class device. It creates instead a link where thesupplier is the parent of the expected device.One consequence is that removal order is not correctly enforced.Issues happen for example with the following sections in a device treeoverlay: // An LED driver chip pca9632@62 { compatible = "nxp,pca9632"; reg = <0x62>; // ... addon_led_pwm: led-pwm@3 { reg = <3>; label = "addon:led:pwm"; }; }; backlight-addon { compatible = "led-backlight"; leds = <&addon_led_pwm>; brightness-levels = <255>; default-brightness-level = <255>; };In this example, the devlink should be created between the backlight-addon(consumer) and the pca9632@62 (supplier). Instead it is created between thebacklight-addon (consumer) and the parent of the pca9632@62, which istypically the I2C bus adapter.On removal of the above overlay, the LED driver can be removed before thebacklight device, resulting in: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000010 ...

The first check correctly accounts forndpoffset: if ((ndpoffset + sizeof(struct usb_cdc_ncm_ndp16)) > skb_in->len)but the second check omits it: if ((sizeof(struct usb_cdc_ncm_ndp16) + ret * (sizeof(struct usb_cdc_ncm_dpe16))) > skb_in->len)This validates the DPE array size against the total skb length as ifthe NDP were at offset 0, rather than at ndpoffset. When the NDP isplaced near the end of the NTB (large wNdpIndex), the DPE entries canextend past the skb data buffer even though the check passes.cdc_ncm_rx_fixup() then reads out-of-bounds memory when iteratingthe DPE array.Add ndpoffset to the nframes bounds check and use struct_size_t() toexpress the NDP-plus-DPE-array size more clearly.

CVE-2026-23465 Severity: Moderate CVSS3 score: 6.1

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

CVE-2026-31503 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-2026-31619 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: fireworks: bound device-supplied status before string array lookupThe status field in an EFW response is a 32-bit value supplied by thefirewire device. efr_status_names[] has 17 entries so a status valueoutside that range goes off into the weeds when looking at the %s value.Even worse, the status could return EFR_STATUS_INCOMPLETE which is0x80000000, and is obviously not in that array of potential strings.Fix this up by properly bounding the index against the array size andprinting "unknown" if it's not recognized.

CVE-2026-31724 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: f_eem: Fix net_device lifecycle with device_moveThe net_device is allocated during function instance creation andregistered during the bind phase with the gadget device as its sysfsparent. When the function unbinds, the parent device is destroyed, butthe net_device survives, resulting in dangling sysfs symlinks:console:/ # ls -l /sys/class/net/usb0lrwxrwxrwx ... /sys/class/net/usb0 ->/sys/devices/platform/.../gadget.0/net/usb0console:/ # ls -l /sys/devices/platform/.../gadget.0/net/usb0ls: .../gadget.0/net/usb0: No such file or directoryUse device_move() to reparent the net_device between the gadget devicetree and /sys/devices/virtual across bind and unbind cycles. During thefinal unbind, calling device_move(NULL) moves the net_device to thevirtual device tree before the gadget device is destroyed. On rebinding,device_move() reparents the device back under the new gadget, ensuringproper sysfs topology and power management ordering.To maintain compatibility with legacy composite drivers (e.g., multi.c),the bound flag is used to indicate whether the network device is sharedand pre-registered during the legacy driver's bind phase.

CVE-2026-31778 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: caiaq: fix stack out-of-bounds read in init_cardThe loop creates a whitespace-stripped copy of the card shortnamewhere `len < sizeof(card->id)` is used for the bounds check. Sincesizeof(card->id) is 16 and the local id buffer is also 16 bytes,writing 16 non-space characters fills the entire buffer,overwriting the terminating nullbyte.When this non-null-terminated string is later passed tosnd_card_set_id() -> copy_valid_id_string(), the function scansforward with `while (*nid && ...)` and reads past the end of thestack buffer, reading the contents of the stack.A USB device with a product name containing many non-ASCII, non-spacecharacters (e.g. multibyte UTF-8) will reliably trigger this as follows: BUG: KASAN: stack-out-of-bounds in copy_valid_id_string sound/core/init.c:696 [inline] BUG: KASAN: stack-out-of-bounds in snd_card_set_id_no_lock+0x698/0x74c sound/core/init.c:718The off-by-one has been present since commit bafeee5b1f8d ("ALSA:snd_usb_caiaq: give better shortname") from June 2009 (v2.6.31-rc1),which first introduced this whitespace-stripping loop. The originalcode never accounted for the null terminator when bounding the copy.Fix this by changing the loop bound to `sizeof(card->id) - 1`,ensuring at least one byte remains as the null terminator.

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.

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: account for current allocated stack depth in widen_imprecise_scalars()The usage pattern for widen_imprecise_scalars() looks as follows: prev_st = find_prev_entry(env, ...); queued_st = push_stack(...); widen_imprecise_scalars(env, prev_st, queued_st);Where prev_st is an ancestor of the queued_st in the explored statestree. This ancestor is not guaranteed to have same allocated stackdepth as queued_st. E.g. in the following case: def main(): for i in 1..2: foo(i) // same callsite, differnt param def foo(i): if i == 1: use 128 bytes of stack iterator based loopHere, for a second 'foo' call prev_st->allocated_stack is 128,while queued_st->allocated_stack is much smaller.widen_imprecise_scalars() needs to take this into account and avoidaccessing bpf_verifier_state->frame[*]->stack out of bounds.

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

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

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

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

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-2025-68972 Severity: Moderate CVSS3 score: 5.9

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

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

CVE-2022-49939 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:binder: fix UAF of ref->proc caused by race conditionA transaction of type BINDER_TYPE_WEAK_HANDLE can fail to increment thereference for a node. In this case, the target proc normally releasesthe failed reference upon close as expected. However, if the target isdying in parallel the call will race with binder_deferred_release(), sothe target could have released all of its references by now leaving thecleanup of the new failed reference unhandled.The transaction then ends and the target proc gets released making theref->proc now a dangling pointer. Later on, ref->node is closed and weattempt to take spin_lock(&ref->proc->inner_lock), which leads to theuse-after-free bug reported below. Let's fix this by cleaning up thefailed reference on the spot instead of relying on the target to do so. ================================================================== BUG: KASAN: use-after-free in _raw_spin_lock+0xa8/0x150 Write of size 4 at addr ffff5ca207094238 by task kworker/1:0/590 CPU: 1 PID: 590 Comm: kworker/1:0 Not tainted 5.19.0-rc8 #10 Hardware name: linux,dummy-virt (DT) Workqueue: events binder_deferred_func Call trace: dump_backtrace.part.0+0x1d0/0x1e0 show_stack+0x18/0x70 dump_stack_lvl+0x68/0x84 print_report+0x2e4/0x61c kasan_report+0xa4/0x110 kasan_check_range+0xfc/0x1a4 __kasan_check_write+0x3c/0x50 _raw_spin_lock+0xa8/0x150 binder_deferred_func+0x5e0/0x9b0 process_one_work+0x38c/0x5f0 worker_thread+0x9c/0x694 kthread+0x188/0x190 ret_from_fork+0x10/0x20

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amd/display: Fix slab-use-after-free in hdcpThe HDCP code in amdgpu_dm_hdcp.c copies pointers to amdgpu_dm_connectorobjects without incrementing the kref reference counts. When using aUSB-C dock, and the dock is unplugged, the correspondingamdgpu_dm_connector objects are freed, creating dangling pointers in theHDCP code.

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

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

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

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: mvsas: Fix use-after-free bugs in mvs_work_queueDuring the detaching of Marvell's SAS/SATA controller, the original codecalls cancel_delayed_work() in mvs_free() to cancel the delayed workitem mwq->work_q. However, if mwq->work_q is already running, thecancel_delayed_work() may fail to cancel it. This can lead touse-after-free scenarios where mvs_free() frees the mvs_info whilemvs_work_queue() is still executing and attempts to access thealready-freed mvs_info.A typical race condition is illustrated below:CPU 0 (remove) | CPU 1 (delayed work callback)mvs_pci_remove() | mvs_free() | mvs_work_queue() cancel_delayed_work() | kfree(mvi) | | mvi-> // UAFReplace cancel_delayed_work() with cancel_delayed_work_sync() to ensurethat the delayed work item is properly canceled and any executingdelayed work item completes before the mvs_info is deallocated.This bug was found by static analysis.

CVE-2025-40096 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:drm/sched: Fix potential double free in drm_sched_job_add_resv_dependenciesWhen adding dependencies with drm_sched_job_add_dependency(), thatfunction consumes the fence reference both on success and failure, so inthe latter case the dma_fence_put() on the error path (xarray failed toexpand) is a double free.Interestingly this bug appears to have been present ever sincecommit ebd5f74255b9 ("drm/sched: Add dependency tracking"), since the codeback then looked like this:drm_sched_job_add_implicit_dependencies():... for (i = 0; i < fence_count; i++) { ret = drm_sched_job_add_dependency(job, fences[i]); if (ret) break; } for (; i < fence_count; i++) dma_fence_put(fences[i]);Which means for the failing 'i' the dma_fence_put was already a doublefree. Possibly there were no users at that time, or the test cases wereinsufficient to hit it.The bug was then only noticed and fixed aftercommit 9c2ba265352a ("drm/scheduler: use new iterator in drm_sched_job_add_implicit_dependencies v2")landed, with its fixup ofcommit 4eaf02d6076c ("drm/scheduler: fix drm_sched_job_add_implicit_dependencies").At that point it was a slightly different flavour of a double free, whichcommit 963d0b356935 ("drm/scheduler: fix drm_sched_job_add_implicit_dependencies harder")noticed and attempted to fix.But it only moved the double free from happening inside thedrm_sched_job_add_dependency(), when releasing the reference not yetobtained, to the caller, when releasing the reference already released bythe former in the failure case.As such it is not easy to identify the right target for the fixes tag solets keep it simple and just continue the chain.While fixing we also improve the comment and explain the reason for takingthe reference and not dropping it.

CVE-2025-68795 Severity: Moderate CVSS3 score: 5.8

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

Description: Closing of an event channel in the Linux kernel can result in a deadlock.This happens when the close is being performed in parallel to an unrelatedXen console action and the handling of a Xen console interrupt in anunprivileged guest.The closing of an event channel is e.g. triggered by removal of aparavirtual device on the other side. As this action will cause consolemessages to be issued on the other side quite often, the chance oftriggering the deadlock is not neglectable.Note that 32-bit Arm-guests are not affected, as the 32-bit Linux kernelon Arm doesn't use queued-RW-locks, which are required to trigger theissue (on Arm32 a waiting writer doesn't block further readers to getthe lock).

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

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

CVE-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-2026-23359 Severity: Moderate CVSS3 score: 5.6

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix stack-out-of-bounds write in devmapget_upper_ifindexes() iterates over all upper devices and writes theirindices into an array without checking bounds.Also the callers assume that the max number of upper devices isMAX_NEST_DEV and allocate excluded_devices[1+MAX_NEST_DEV] on the stack,but that assumption is not correct and the number of upper devices couldbe larger than MAX_NEST_DEV (e.g., many macvlans), causing astack-out-of-bounds write.Add a max parameter to get_upper_ifindexes() to avoid the issue.When there are too many upper devices, return -EOVERFLOW and abort theredirect.To reproduce, create more than MAX_NEST_DEV(8) macvlans on a device withan XDP program attached using BPF_F_BROADCAST | BPF_F_EXCLUDE_INGRESS.Then send a packet to the device to trigger the XDP redirect path.

CVE-2026-31675 Severity: Moderate CVSS3 score: 5.6

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: sch_netem: fix out-of-bounds access in packet corruptionIn netem_enqueue(), the packet corruption logic usesget_random_u32_below(skb_headlen(skb)) to select an index formodifying skb->data. When an AF_PACKET TX_RING sends fully non-linearpackets over an IPIP tunnel, skb_headlen(skb) evaluates to 0.Passing 0 to get_random_u32_below() takes the variable-ceil slow pathwhich returns an unconstrained 32-bit random integer. Using thisunconstrained value as an offset into skb->data results in anout-of-bounds memory access.Fix this by verifying skb_headlen(skb) is non-zero before attemptingto corrupt the linear data area. Fully non-linear packets will silentlybypass the corruption logic.

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

CVE-2026-43037 Severity: Important CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ip6_tunnel: clear skb2->cb[] in ip4ip6_err()Oskar Kjos reported the following problem.ip4ip6_err() calls icmp_send() on a cloned skb whose cb[] was writtenby the IPv6 receive path as struct inet6_skb_parm. icmp_send() passesIPCB(skb2) to __ip_options_echo(), which interprets that cb[] regionas struct inet_skb_parm (IPv4). The layouts differ: inet6_skb_parm.nhoffat offset 14 overlaps inet_skb_parm.opt.rr, producing a non-zero rrvalue. __ip_options_echo() then reads optlen from attacker-controlledpacket data at sptr[rr+1] and copies that many bytes into dopt->__data,a fixed 40-byte stack buffer (IP_OPTIONS_DATA_FIXED_SIZE).To fix this we clear skb2->cb[], as suggested by Oskar Kjos.Also add minimal IPv4 header validation (version == 4, ihl >= 5).

CVE-2026-43038 Severity: Important CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()Sashiko AI-review observed: In ip6_err_gen_icmpv6_unreach(), the skb is an outer IPv4 ICMP error packet where its cb contains an IPv4 inet_skb_parm. When skb is cloned into skb2 and passed to icmp6_send(), it uses IP6CB(skb2). IP6CB interprets the IPv4 inet_skb_parm as an inet6_skb_parm. The cipso offset in inet_skb_parm.opt directly overlaps with dsthao in inet6_skb_parm at offset 18. If an attacker sends a forged ICMPv4 error with a CIPSO IP option, dsthao would be a non-zero offset. Inside icmp6_send(), mip6_addr_swap() is called and uses ipv6_find_tlv(skb, opt->dsthao, IPV6_TLV_HAO). This would scan the inner, attacker-controlled IPv6 packet starting at that offset, potentially returning a fake TLV without checking if the remaining packet length can hold the full 18-byte struct ipv6_destopt_hao. Could mip6_addr_swap() then perform a 16-byte swap that extends past the end of the packet data into skb_shared_info? Should the cb array also be cleared in ip6_err_gen_icmpv6_unreach() and ip6ip6_err() to prevent this?This patch implements the first suggestion.I am not sure if ip6ip6_err() needs to be changed.A separate patch would be better anyway.

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

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

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

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

The original check was if (csum && skb_checksum_start(skb) < skb->data) return -EINVAL;This had false positives when skb_checksum_start is undefined:when ip_summed is not CHECKSUM_PARTIAL. A discussed refinementwas straightforward if (csum && skb->ip_summed == CHECKSUM_PARTIAL && skb_checksum_start(skb) < skb->data) return -EINVAL;But was eventually revised more thoroughly:- restrict the check to the only branch where needed, in an uncommon GRE path that uses header_ops and calls skb_pull.- test skb_transport_header, which is set along with csum_start in skb_partial_csum_set in the normal header_ops datapath.Turns out skbs can arrive in this branch without the transportheader set, e.g., through BPF redirection.Revise the check back to check csum_start directly, and only ifCHECKSUM_PARTIAL.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: always report error in run_one_delayed_ref()Currently we have a btrfs_debug() for run_one_delayed_ref() failure, butif end users hit such problem, there will be no chance thatbtrfs_debug() is enabled. This can lead to very little useful info fordebugging.This patch will:- Add extra info for error reporting Including: * logical bytenr * num_bytes * type * action * ref_mod- Replace the btrfs_debug() with btrfs_err()- Move the error reporting into run_one_delayed_ref() This is to avoid use-after-free, the @node can be freed in the caller.This error should only be triggered at most once.As if run_one_delayed_ref() failed, we trigger the error message, thencausing the call chain to error out:btrfs_run_delayed_refs()`- btrfs_run_delayed_refs() `- btrfs_run_delayed_refs_for_head() `- run_one_delayed_ref()And we will abort the current transaction in btrfs_run_delayed_refs().If we have to run delayed refs for the abort transaction,run_one_delayed_ref() will just cleanup the refs and do nothing, thus nonew error messages would be output.

CVE-2022-49808 Severity: Moderate CVSS3 score: 5.5

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

CVE-2022-49828 Severity: Moderate CVSS3 score: 5.5

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

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

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

This only happenswith multiple subprogs. In jit_subprogs(), we first call bpf_int_jit_compile()on each sub program.

Description: In the Linux kernel, the following vulnerability has been resolved:sctp: handle the error returned from sctp_auth_asoc_init_active_keyWhen it returns an error from sctp_auth_asoc_init_active_key(), theactive_key is actually not updated. The old sh_key will be freeedwhile it's still used as active key in asoc. Then an use-after-freewill be triggered when sending patckets, as found by syzbot: sctp_auth_shkey_hold+0x22/0xa0 net/sctp/auth.c:112 sctp_set_owner_w net/sctp/socket.c:132 [inline] sctp_sendmsg_to_asoc+0xbd5/0x1a20 net/sctp/socket.c:1863 sctp_sendmsg+0x1053/0x1d50 net/sctp/socket.c:2025 inet_sendmsg+0x99/0xe0 net/ipv4/af_inet.c:819 sock_sendmsg_nosec net/socket.c:714 [inline] sock_sendmsg+0xcf/0x120 net/socket.c:734This patch is to fix it by not replacing the sh_key when it returnserrors from sctp_auth_asoc_init_active_key() in sctp_auth_set_key().For sctp_auth_set_active_key(), old active_key_id will be set backto asoc->active_key_id when the same thing happens.

CVE-2022-50244 Severity: Moderate CVSS3 score: 5.5

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

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

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

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

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

CVE-2023-52638 Severity: Moderate CVSS3 score: 5.5

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

CVE-2023-52648 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:drm/vmwgfx: Unmap the surface before resetting it on a plane stateSwitch to a new plane state requires unreferencing of all held surfaces.In the work required for mob cursors the mapped surfaces started beingcached but the variable indicating whether the surface is currentlymapped was not being reset. This leads to crashes as the duplicatedstate, incorrectly, indicates the that surface is mapped even whenno surface is present. That's because after unreferencing the surfaceit's perfectly possible for the plane to be backed by a bo instead of asurface.Reset the surface mapped flag when unreferencing the plane state surfaceto fix null derefs in cleanup.

Description: In the Linux kernel, the following vulnerability has been resolved:arm64: Restrict CPU_BIG_ENDIAN to GNU as or LLVM IAS 15.x or newerPrior to LLVM 15.0.0, LLVM's integrated assembler would incorrectlybyte-swap NOP when compiling for big-endian, and the resulting series ofbytes happened to match the encoding of FNMADD S21, S30, S0, S0.This went unnoticed until commit: 34f66c4c4d5518c1 ("arm64: Use a positive cpucap for FP/SIMD")Prior to that commit, the kernel would always enable the use of FPSIMDearly in boot when __cpu_setup() initialized CPACR_EL1, and so usage ofFNMADD within the kernel was not detected, but could result in thecorruption of user or kernel FPSIMD state.After that commit, the instructions happen to trap during boot prior toFPSIMD being detected and enabled, e.g.| Unhandled 64-bit el1h sync exception on CPU0, ESR 0x000000001fe00000 -- ASIMD| CPU: 0 PID: 0 Comm: swapper Not tainted 6.6.0-rc3-00013-g34f66c4c4d55 #1| Hardware name: linux,dummy-virt (DT)| pstate: 400000c9 (nZcv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--)| pc : __pi_strcmp+0x1c/0x150| lr : populate_properties+0xe4/0x254| sp : ffffd014173d3ad0| x29: ffffd014173d3af0 x28: fffffbfffddffcb8 x27: 0000000000000000| x26: 0000000000000058 x25: fffffbfffddfe054 x24: 0000000000000008| x23: fffffbfffddfe000 x22: fffffbfffddfe000 x21: fffffbfffddfe044| x20: ffffd014173d3b70 x19: 0000000000000001 x18: 0000000000000005| x17: 0000000000000010 x16: 0000000000000000 x15: 00000000413e7000| x14: 0000000000000000 x13: 0000000000001bcc x12: 0000000000000000| x11: 00000000d00dfeed x10: ffffd414193f2cd0 x9 : 0000000000000000| x8 : 0101010101010101 x7 : ffffffffffffffc0 x6 : 0000000000000000| x5 : 0000000000000000 x4 : 0101010101010101 x3 : 000000000000002a| x2 : 0000000000000001 x1 : ffffd014171f2988 x0 : fffffbfffddffcb8| Kernel panic - not syncing: Unhandled exception| CPU: 0 PID: 0 Comm: swapper Not tainted 6.6.0-rc3-00013-g34f66c4c4d55 #1| Hardware name: linux,dummy-virt (DT)| Call trace:| dump_backtrace+0xec/0x108| show_stack+0x18/0x2c| dump_stack_lvl+0x50/0x68| dump_stack+0x18/0x24| panic+0x13c/0x340| el1t_64_irq_handler+0x0/0x1c| el1_abort+0x0/0x5c| el1h_64_sync+0x64/0x68| __pi_strcmp+0x1c/0x150| unflatten_dt_nodes+0x1e8/0x2d8| __unflatten_device_tree+0x5c/0x15c| unflatten_device_tree+0x38/0x50| setup_arch+0x164/0x1e0| start_kernel+0x64/0x38c| __primary_switched+0xbc/0xc4Restrict CONFIG_CPU_BIG_ENDIAN to a known good assembler, which iseither GNU as or LLVM's IAS 15.0.0 and newer, which contains the linkedcommit.

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:rcu: Protect rcu_print_task_exp_stall() ->exp_tasks accessFor kernels built with CONFIG_PREEMPT_RCU=y, the following scenario canresult in a NULL-pointer dereference: CPU1 CPU2rcu_preempt_deferred_qs_irqrestore rcu_print_task_exp_stall if (special.b.blocked) READ_ONCE(rnp->exp_tasks) != NULL raw_spin_lock_rcu_node np = rcu_next_node_entry(t, rnp) if (&t->rcu_node_entry == rnp->exp_tasks) WRITE_ONCE(rnp->exp_tasks, np) .... raw_spin_unlock_irqrestore_rcu_node raw_spin_lock_irqsave_rcu_node t = list_entry(rnp->exp_tasks->prev, struct task_struct, rcu_node_entry) (if rnp->exp_tasks is NULL, this will dereference a NULL pointer)The problem is that CPU2 accesses the rcu_node structure's->exp_tasksfield without holding the rcu_node structure's ->lock and CPU2 didnot observe CPU1's change to rcu_node structure's ->exp_tasks in time.Therefore, if CPU1 sets rcu_node structure's->exp_tasks pointer to NULL,then CPU2 might dereference that NULL pointer.This commit therefore holds the rcu_node structure's ->lock whileaccessing that structure's->exp_tasks field.[ paulmck: Apply Frederic Weisbecker feedback. ]

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

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

CVE-2023-53618 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: reject invalid reloc tree root keys with stack dump[BUG]Syzbot reported a crash that an ASSERT() got triggered insideprepare_to_merge().That ASSERT() makes sure the reloc tree is properly pointed back by itssubvolume tree.[CAUSE]After more debugging output, it turns out we had an invalid reloc tree: BTRFS error (device loop1): reloc tree mismatch, root 8 has no reloc root, expect reloc root key (-8, 132, 8) gen 17Note the above root key is (TREE_RELOC_OBJECTID, ROOT_ITEM,QUOTA_TREE_OBJECTID), meaning it's a reloc tree for quota tree.But reloc trees can only exist for subvolumes, as for non-subvolumetrees, we just COW the involved tree block, no need to create a reloctree since those tree blocks won't be shared with other trees.Only subvolumes tree can share tree blocks with other trees (thus theyhave BTRFS_ROOT_SHAREABLE flag).Thus this new debug output proves my previous assumption that corruptedon-disk data can trigger that ASSERT().[FIX]Besides the dedicated fix and the graceful exit, also let tree-checker tocheck such root keys, to make sure reloc trees can only exist for subvolumes.

Description: In the Linux kernel, the following vulnerability has been resolved:md: fix soft lockup in status_resyncstatus_resync() will calculate 'curr_resync - recovery_active' to showuser a progress bar like following:[============>........] resync = 61.4%'curr_resync' and 'recovery_active' is updated in md_do_sync(), andstatus_resync() can read them concurrently, hence it's possible that'curr_resync - recovery_active' can overflow to a huge number. In thiscase status_resync() will be stuck in the loop to print a large amountof '=', which will end up soft lockup.Fix the problem by setting 'resync' to MD_RESYNC_ACTIVE in this case,this way resync in progress will be reported to user.

CVE-2023-53684 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:xfrm: Zero padding when dumping algos and encapWhen copying data to user-space we should ensure that only validdata is copied over. Padding in structures may be filled withrandom (possibly sensitve) data and should never be given directlyto user-space.This patch fixes the copying of xfrm algorithms and the encaptemplate in xfrm_user so that padding is zeroed.

CVE-2023-53785 Severity: Moderate CVSS3 score: 5.5

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

CVE-2023-53798 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ethtool: Fix uninitialized number of lanesIt is not possible to set the number of lanes when setting link modesusing the legacy IOCTL ethtool interface. Since 'structethtool_link_ksettings' is not initialized in this path, drivers receivean uninitialized number of lanes in 'structethtool_link_ksettings::lanes'.When this information is later queried from drivers, it results in theethtool code making decisions based on uninitialized memory, leading tothe following KMSAN splat [1]. In practice, this most likely onlyhappens with the tun driver that simply returns whatever it got in theset operation.As far as I can tell, this uninitialized memory is not leaked to userspace thanks to the 'ethtool_ops->cap_link_lanes_supported' check inlinkmodes_prepare_data().Fix by initializing the structure in the IOCTL path. Did not find anymore call sites that pass an uninitialized structure when calling'ethtool_ops::set_link_ksettings()'.[1]BUG: KMSAN: uninit-value in ethnl_update_linkmodes net/ethtool/linkmodes.c:273 [inline]BUG: KMSAN: uninit-value in ethnl_set_linkmodes+0x190b/0x19d0 net/ethtool/linkmodes.c:333 ethnl_update_linkmodes net/ethtool/linkmodes.c:273 [inline] ethnl_set_linkmodes+0x190b/0x19d0 net/ethtool/linkmodes.c:333 ethnl_default_set_doit+0x88d/0xde0 net/ethtool/netlink.c:640 genl_family_rcv_msg_doit net/netlink/genetlink.c:968 [inline] genl_family_rcv_msg net/netlink/genetlink.c:1048 [inline] genl_rcv_msg+0x141a/0x14c0 net/netlink/genetlink.c:1065 netlink_rcv_skb+0x3f8/0x750 net/netlink/af_netlink.c:2577 genl_rcv+0x40/0x60 net/netlink/genetlink.c:1076 netlink_unicast_kernel net/netlink/af_netlink.c:1339 [inline] netlink_unicast+0xf41/0x1270 net/netlink/af_netlink.c:1365 netlink_sendmsg+0x127d/0x1430 net/netlink/af_netlink.c:1942 sock_sendmsg_nosec net/socket.c:724 [inline] sock_sendmsg net/socket.c:747 [inline] ____sys_sendmsg+0xa24/0xe40 net/socket.c:2501 ___sys_sendmsg+0x2a1/0x3f0 net/socket.c:2555 __sys_sendmsg net/socket.c:2584 [inline] __do_sys_sendmsg net/socket.c:2593 [inline] __se_sys_sendmsg net/socket.c:2591 [inline] __x64_sys_sendmsg+0x36b/0x540 net/socket.c:2591 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x41/0xc0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcdUninit was stored to memory at: tun_get_link_ksettings+0x37/0x60 drivers/net/tun.c:3544 __ethtool_get_link_ksettings+0x17b/0x260 net/ethtool/ioctl.c:441 ethnl_set_linkmodes+0xee/0x19d0 net/ethtool/linkmodes.c:327 ethnl_default_set_doit+0x88d/0xde0 net/ethtool/netlink.c:640 genl_family_rcv_msg_doit net/netlink/genetlink.c:968 [inline] genl_family_rcv_msg net/netlink/genetlink.c:1048 [inline] genl_rcv_msg+0x141a/0x14c0 net/netlink/genetlink.c:1065 netlink_rcv_skb+0x3f8/0x750 net/netlink/af_netlink.c:2577 genl_rcv+0x40/0x60 net/netlink/genetlink.c:1076 netlink_unicast_kernel net/netlink/af_netlink.c:1339 [inline] netlink_unicast+0xf41/0x1270 net/netlink/af_netlink.c:1365 netlink_sendmsg+0x127d/0x1430 net/netlink/af_netlink.c:1942 sock_sendmsg_nosec net/socket.c:724 [inline] sock_sendmsg net/socket.c:747 [inline] ____sys_sendmsg+0xa24/0xe40 net/socket.c:2501 ___sys_sendmsg+0x2a1/0x3f0 net/socket.c:2555 __sys_sendmsg net/socket.c:2584 [inline] __do_sys_sendmsg net/socket.c:2593 [inline] __se_sys_sendmsg net/socket.c:2591 [inline] __x64_sys_sendmsg+0x36b/0x540 net/socket.c:2591 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x41/0xc0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcdUninit was stored to memory at: tun_set_link_ksettings+0x37/0x60 drivers/net/tun.c:3553 ethtool_set_link_ksettings+0x600/0x690 net/ethtool/ioctl.c:609 __dev_ethtool net/ethtool/ioctl.c:3024 [inline] dev_ethtool+0x1db9/0x2a70 net/ethtool/ioctl.c:3078 dev_ioctl+0xb07/0x1270 net/core/dev_ioctl.c:524 sock_do_ioctl+0x295/0x540 net/socket.c:1213 sock_i---truncated---

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: ath11k: Ignore frags from uninitialized peer in dp.When max virtual ap interfaces are configured in all the bands withACS and hostapd restart is done every 60s, a crash is observed atrandom times.In this certain scenario, a fragmented packet is received forself peer, for which rx_tid and rx_frags are not initialized indatapath. While handling this fragment, crash is observed as therx_frag list is uninitialised and when we walk inath11k_dp_rx_h_sort_frags, skb null leads to exception.To address this, before processing received fragments we checkdp_setup_done flag is set to ensure that peer has completed itsdp peer setup for fragment queue, else ignore processing thefragments.Call trace: ath11k_dp_process_rx_err+0x550/0x1084 [ath11k] ath11k_dp_service_srng+0x70/0x370 [ath11k] 0xffffffc009693a04 __napi_poll+0x30/0xa4 net_rx_action+0x118/0x270 __do_softirq+0x10c/0x244 irq_exit+0x64/0xb4 __handle_domain_irq+0x88/0xac gic_handle_irq+0x74/0xbc el1_irq+0xf0/0x1c0 arch_cpu_idle+0x10/0x18 do_idle+0x104/0x248 cpu_startup_entry+0x20/0x64 rest_init+0xd0/0xdc arch_call_rest_init+0xc/0x14 start_kernel+0x480/0x4b8 Code: f9400281 f94066a2 91405021 b94a0023 (f9406401)Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1

CVE-2023-53823 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:block/rq_qos: protect rq_qos apis with a new lockcommit 50e34d78815e ("block: disable the elevator int del_gendisk")move rq_qos_exit() from disk_release() to del_gendisk(), this willintroduce some problems:1) If rq_qos_add() is triggered by enabling iocost/iolatency through cgroupfs, then it can concurrent with del_gendisk(), it's not safe to write 'q->rq_qos' concurrently.2) Activate cgroup policy that is relied on rq_qos will call rq_qos_add() and blkcg_activate_policy(), and if rq_qos_exit() is called in the middle, null-ptr-dereference will be triggered in blkcg_activate_policy().3) blkg_conf_open_bdev() can call blkdev_get_no_open() first to find the disk, then if rq_qos_exit() from del_gendisk() is done before rq_qos_add(), then memory will be leaked.This patch add a new disk level mutex 'rq_qos_mutex':1) The lock will protect rq_qos_exit() directly.2) For wbt that doesn't relied on blk-cgroup, rq_qos_add() can only be called from disk initialization for now because wbt can't be destructed until rq_qos_exit(), so it's safe not to protect wbt for now. Hoever, in case that rq_qos dynamically destruction is supported in the furture, this patch also protect rq_qos_add() from wbt_init() directly, this is enough because blk-sysfs already synchronize writers with disk removal.3) For iocost and iolatency, in order to synchronize disk removal and cgroup configuration, the lock is held after blkdev_get_no_open() from blkg_conf_open_bdev(), and is released in blkg_conf_exit(). In order to fix the above memory leak, disk_live() is checked after holding the new lock.

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:drm/msm/dp: Drop aux devices together with DP controllerUsing devres to depopulate the aux bus made sure that upon a probedeferral the EDP panel device would be destroyed and recreated upon nextattempt.But the struct device which the devres is tied to is the DPUs(drm_dev->dev), which may be happen after the DP controller is torndown.Indications of this can be seen in the commonly seen EDID-hexdump fullof zeros in the log, or the occasional/rare KASAN fault where thepanel's attempt to read the EDID information causes a use after free onDP resources.It's tempting to move the devres to the DP controller's struct device,but the resources used by the device(s) on the aux bus are explicitlytorn down in the error path. The KASAN-reported use-after-free alsoremains, as the DP aux "module" explicitly frees its devres-allocatedmemory in this code path.As such, explicitly depopulate the aux bus in the error path, and in thecomponent unbind path, to avoid these issues.Patchwork: https://patchwork.freedesktop.org/patch/542163/

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

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

In particular for task local storage, it is easy toget a "current" task PTR_TO_BTF_ID in tracing bpf prog.However, task (and cgroup) local storage has already been moved tobpf mem allocator which can be used after raw_spin_lock.The splat is for the sk storage. For sk (and inode) storage,it has not been moved to bpf mem allocator. Using raw_spin_lock or not,kzalloc(GFP_ATOMIC) could theoretically be unsafe in tracing context.However, the local storage helper requires a verifier acceptedsk pointer (PTR_TO_BTF_ID), it is hypothetical if that (mean runninga bpf prog in a kzalloc unsafe context and also able to hold a verifieraccepted sk pointer) could happen.This patch avoids kzalloc after raw_spin_lock to silent the splat.There is an existing kzalloc before the raw_spin_lock. At that point,a kzalloc is very likely required because a lookup has just been donebefore. Thus, this patch always does the kzalloc before acq---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5e: TC, Fix internal port memory leakThe flow rule can be splited, and the extra post_act rules are addedto post_act table. It's possible to trigger memleak when the ruleforwards packets from internal port and over tunnel, in the case that,for example, CT 'new' state offload is allowed. As int_port object isassigned to the flow attribute of post_act rule, and its refcnt isincremented by mlx5e_tc_int_port_get(), but mlx5e_tc_int_port_put() isnot called, the refcnt is never decremented, then int_port is neverfreed.The kmemleak reports the following error:unreferenced object 0xffff888128204b80 (size 64): comm "handler20", pid 50121, jiffies 4296973009 (age 642.932s) hex dump (first 32 bytes): 01 00 00 00 19 00 00 00 03 f0 00 00 04 00 00 00 ................ 98 77 67 41 81 88 ff ff 98 77 67 41 81 88 ff ff .wgA.....wgA.... backtrace: [<00000000e992680d>] kmalloc_trace+0x27/0x120 [<000000009e945a98>] mlx5e_tc_int_port_get+0x3f3/0xe20 [mlx5_core] [<0000000035a537f0>] mlx5e_tc_add_fdb_flow+0x473/0xcf0 [mlx5_core] [<0000000070c2cec6>] __mlx5e_add_fdb_flow+0x7cf/0xe90 [mlx5_core] [<000000005cc84048>] mlx5e_configure_flower+0xd40/0x4c40 [mlx5_core] [<000000004f8a2031>] mlx5e_rep_indr_offload.isra.0+0x10e/0x1c0 [mlx5_core] [<000000007df797dc>] mlx5e_rep_indr_setup_tc_cb+0x90/0x130 [mlx5_core] [<0000000016c15cc3>] tc_setup_cb_add+0x1cf/0x410 [<00000000a63305b4>] fl_hw_replace_filter+0x38f/0x670 [cls_flower] [<000000008bc9e77c>] fl_change+0x1fd5/0x4430 [cls_flower] [<00000000e7f766e4>] tc_new_tfilter+0x867/0x2010 [<00000000e101c0ef>] rtnetlink_rcv_msg+0x6fc/0x9f0 [<00000000e1111d44>] netlink_rcv_skb+0x12c/0x360 [<0000000082dd6c8b>] netlink_unicast+0x438/0x710 [<00000000fc568f70>] netlink_sendmsg+0x794/0xc50 [<0000000016e92590>] sock_sendmsg+0xc5/0x190So fix this by moving int_port cleanup code to the flow attributefree helper, which is used by all the attribute free cases.

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:ubi: Fix possible null-ptr-deref in ubi_free_volume()It willl cause null-ptr-deref in the following case:uif_init() ubi_add_volume() cdev_add() -> if it fails, call kill_volumes() device_register()kill_volumes() -> if ubi_add_volume() fails call this function ubi_free_volume() cdev_del() device_unregister() -> trying to delete a not added device, it causes null-ptr-derefSo in ubi_free_volume(), it delete devices whether they are addedor not, it will causes null-ptr-deref.Handle the error case whlie calling ubi_add_volume() to fix thisproblem. If add volume fails, set the corresponding vol to null,so it can not be accessed in kill_volumes() and release theresource in ubi_add_volume() error path.

Description: In the Linux kernel, the following vulnerability has been resolved:media: anysee: fix null-ptr-deref in anysee_master_xferIn anysee_master_xfer, msg is controlled by user. When msg[i].bufis null and msg[i].len is zero, former checks on msg[i].buf would bepassed. Malicious data finally reach anysee_master_xfer. If accessingmsg[i].buf[0] without sanity check, null ptr deref would happen.We add check on msg[i].len to prevent crash.Similar commit:commit 0ed554fd769a("media: dvb-usb: az6027: fix null-ptr-deref in az6027_i2c_xfer()")[hverkuil: add spaces around +]

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

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

CVE-2023-54121 Severity: Moderate CVSS3 score: 5.5

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

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

CVE-2023-54220 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:serial: 8250: Fix oops for port->pm on uart_change_pm()Unloading a hardware specific 8250 driver can produce error "Unable tohandle kernel paging request at virtual address" about ten seconds afterunloading the driver. This happens on uart_hangup() callinguart_change_pm().Turns out commit 04e82793f068 ("serial: 8250: Reinit port->pm on portspecific driver unbind") was only a partial fix. If the hardware specificdriver has initialized port->pm function, we need to clear port->pm too.Just reinitializing port->ops does not do this. Otherwise serial8250_pm()will call port->pm() instead of serial8250_do_pm().

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

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)").

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

CVE-2024-26803 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: veth: clear GRO when clearing XDP even when downveth sets NETIF_F_GRO automatically when XDP is enabled,because both features use the same NAPI machinery.The logic to clear NETIF_F_GRO sits in veth_disable_xdp() whichis called both on ndo_stop and when XDP is turned off.To avoid the flag from being cleared when the device is broughtdown, the clearing is skipped when IFF_UP is not set.Bringing the device down should indeed not modify its features.Unfortunately, this means that clearing is also skipped whenXDP is disabled _while_ the device is down. And there's nothingon the open path to bring the device features back into sync.IOW if user enables XDP, disables it and then brings the deviceup we'll end up with a stray GRO flag set but no NAPI instances.We don't depend on the GRO flag on the datapath, so the datapathwon't crash. We will crash (or hang), however, next time featuresare sync'ed (either by user via ethtool or peer changing its config).The GRO flag will go away, and veth will try to disable the NAPIs.But the open path never created them since XDP was off, the GRO flagwas a stray. If NAPI was initialized before we'll hang in napi_disable().If it never was we'll crash trying to stop uninitialized hrtimer.Move the GRO flag updates to the XDP enable / disable paths,instead of mixing them with the ndo_open / ndo_close paths.

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:md/dm-raid: don't call md_reap_sync_thread() directlyCurrently md_reap_sync_thread() is called from raid_message() directlywithout holding 'reconfig_mutex', this is definitely unsafe becausemd_reap_sync_thread() can change many fields that is protected by'reconfig_mutex'.However, hold 'reconfig_mutex' here is still problematic because thiswill cause deadlock, for example, commit 130443d60b1b ("md: refactoridle/frozen_sync_thread() to fix deadlock").Fix this problem by using stop_sync_thread() to unregister sync_thread,like md/raid did.

CVE-2024-35839 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: bridge: replace physindev with physinif in nf_bridge_infoAn skb can be added to a neigh->arp_queue while waiting for an arpreply. Where original skb's skb->dev can be different to neigh'sneigh->dev. For instance in case of bridging dnated skb from one veth toanother, the skb would be added to a neigh->arp_queue of the bridge.As skb->dev can be reset back to nf_bridge->physindev and used, and asthere is no explicit mechanism that prevents this physindev from beenfreed under us (for instance neigh_flush_dev doesn't cleanup skbs fromdifferent device's neigh queue) we can crash on e.g. this stack:arp_process neigh_update skb = __skb_dequeue(&neigh->arp_queue) neigh_resolve_output(..., skb) ... br_nf_dev_xmit br_nf_pre_routing_finish_bridge_slow skb->dev = nf_bridge->physindev br_handle_frame_finishLet's use plain ifindex instead of net_device link. To peek into theoriginal net_device we will use dev_get_by_index_rcu(). Thus either weget device and are safe to use it or we don't get it and drop skb.

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

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

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

Sincethe NULL check is already performed in pci_epf_test_bind(), having one morecheck in pci_epf_test_core_init() is redundant and it is not possible tohit the NULL pointer dereference.Also with commit a01e7214bef9 ("PCI: endpoint: Remove "core_init_notifier"flag"), 'epc_features' got dereferenced without the NULL check, leading tothe following false positive Smatch warning: drivers/pci/endpoint/functions/pci-epf-test.c:784 pci_epf_test_core_init() error: we previously assumed 'epc_features' could be null (see line 747)Thus, remove the redundant NULL check and also use the epc_features::{msix_capable/msi_capable} flags directly to avoid local variables.[kwilczynski: commit log]

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:ice: protect XDP configuration with a mutexThe main threat to data consistency in ice_xdp() is a possible asynchronousPF reset.

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

When using such a mapping to attempt tofault past the end of the buffer, the CMA heap fault handler also checksthe fault offset against the buffer size, but gets the boundary wrong by1. Fix the boundary check so that we don't read off the end of the pagesarray and insert an arbitrary page in the mapping.

But credits are not yet consumed. This is deferred to 3)2) The per destination limit is checked/updated. This might add a new node in inetpeer tree.3) icmp_global_consume() consumes tokens if prior operations succeeded.This means that host wide ratelimit is still effectivein keeping inetpeer tree small even under DDOS.As a bonus, I removed icmp_global.lock as the fast pathcan use a lock-free operation.

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

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

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

CVE-2024-49998 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: dsa: improve shutdown sequenceAlexander Sverdlin presents 2 problems during shutdown with thelan9303 driver. One is specific to lan9303 and the other just happensto reproduce there.The first problem is that lan9303 is unique among DSA drivers in that itcalls dev_get_drvdata() at "arbitrary runtime" (not probe, not shutdown,not remove):phy_state_machine()-> ... -> dsa_user_phy_read() -> ds->ops->phy_read() -> lan9303_phy_read() -> chip->ops->phy_read() -> lan9303_mdio_phy_read() -> dev_get_drvdata()But we never stop the phy_state_machine(), so it may continue to runafter dsa_switch_shutdown(). Our common pattern in all DSA drivers isto set drvdata to NULL to suppress the remove() method that may comeafterwards. But in this case it will result in an NPD.The second problem is that the way in which we setdp->conduit->dsa_ptr = NULL; is concurrent with receive packetprocessing. dsa_switch_rcv() checks once whether dev->dsa_ptr is NULL,but afterwards, rather than continuing to use that non-NULL value,dev->dsa_ptr is dereferenced again and again without NULL checks:dsa_conduit_find_user() and many other places. In between dereferences,there is no locking to ensure that what was valid once continues to bevalid.Both problems have the common aspect that closing the conduit interfacesolves them.In the first case, dev_close(conduit) triggers the NETDEV_GOING_DOWNevent in dsa_user_netdevice_event() which closes user ports as well.dsa_port_disable_rt() calls phylink_stop(), which synchronously stopsthe phylink state machine, and ds->ops->phy_read() will thus no longercall into the driver after this point.In the second case, dev_close(conduit) should do this, as perDocumentation/networking/driver.rst:| Quiescence| ----------|| After the ndo_stop routine has been called, the hardware must| not receive or transmit any data. All in flight packets must| be aborted. If necessary, poll or wait for completion of| any reset commands.So it should be sufficient to ensure that later, when we zeroizeconduit->dsa_ptr, there will be no concurrent dsa_switch_rcv() callon this conduit.The addition of the netif_device_detach() function is to ensure thatioctls, rtnetlinks and ethtool requests on the user ports no longerpropagate down to the driver - we're no longer prepared to handle them.The race condition actually did not exist when commit 0650bf52b31f("net: dsa: be compatible with masters which unregister on shutdown")first introduced dsa_switch_shutdown(). It was created later, when westopped unregistering the user interfaces from a bad spot, and we justreplaced that sequence with a racy zeroization of conduit->dsa_ptr(one which doesn't ensure that the interfaces aren't up).

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:mm/swapfile: skip HugeTLB pages for unuse_vmaI got a bad pud error and lost a 1GB HugeTLB when calling swapoff. Theproblem can be reproduced by the following steps: 1. Allocate an anonymous 1GB HugeTLB and some other anonymous memory. 2. Swapout the above anonymous memory. 3. run swapoff and we will get a bad pud error in kernel message: mm/pgtable-generic.c:42: bad pud 00000000743d215d(84000001400000e7)We can tell that pud_clear_bad is called by pud_none_or_clear_bad inunuse_pud_range() by ftrace. And therefore the HugeTLB pages will neverbe freed because we lost it from page table. We can skip HugeTLB pagesfor unuse_vma to fix it.

CVE-2024-50202 Severity: Moderate CVSS3 score: 5.5

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

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: iwlwifi: mvm: fix 6 GHz scan constructionIf more than 255 colocated APs exist for the set of allAPs found during 2.4/5 GHz scanning, then the 6 GHz scanconstruction will loop forever since the loop variablehas type u8, which can never reach the number found whenthat's bigger than 255, and is stored in a u32 variable.Also move it into the loops to have a smaller scope.Using a u32 there is fine, we limit the number of APs inthe scan list and each has a limit on the number of RNRentries due to the frame size. With a limit of 1000 scanresults, a frame size upper bound of 4096 (really it'smore like ~2300) and a TBTT entry size of at least 11,we get an upper bound for the number of ~372k, well inthe bounds of a u32.

CVE-2024-53095 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: Fix use-after-free of network namespace.Recently, we got a customer report that CIFS triggers oops whilereconnecting to a server. [0]The workload runs on Kubernetes, and some pods mount CIFS serversin non-root network namespaces. The problem rarely happened, butit was always while the pod was dying.The root cause is wrong reference counting for network namespace.CIFS uses kernel sockets, which do not hold refcnt of the netns thatthe socket belongs to. That means CIFS must ensure the socket isalways freed before its netns; otherwise, use-after-free happens.The repro steps are roughly: 1. mount CIFS in a non-root netns 2. drop packets from the netns 3. destroy the netns 4. unmount CIFSWe can reproduce the issue quickly with the script [1] below and seethe splat [2] if CONFIG_NET_NS_REFCNT_TRACKER is enabled.When the socket is TCP, it is hard to guarantee the netns lifetimewithout holding refcnt due to async timers.Let's hold netns refcnt for each socket as done for SMC in commit9744d2bf1976 ("smc: Fix use-after-free in tcp_write_timer_handler().").Note that we need to move put_net() from cifs_put_tcp_session() toclean_demultiplex_info(); otherwise, __sock_create() still could touch afreed netns while cifsd tries to reconnect from cifs_demultiplex_thread().Also, maybe_get_net() cannot be put just before __sock_create() becausethe code is not under RCU and there is a small chance that the sameaddress happened to be reallocated to another netns.[0]:CIFS: VFS: \\XXXXXXXXXXX has not responded in 15 seconds.

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

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

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

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

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

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

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

CVE-2024-53135 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: VMX: Bury Intel PT virtualization (guest/host mode) behind CONFIG_BROKENHide KVM's pt_mode module param behind CONFIG_BROKEN, i.e. disable supportfor virtualizing Intel PT via guest/host mode unless BROKEN=y. There aremyriad bugs in the implementation, some of which are fatal to the guest,and others which put the stability and health of the host at risk.For guest fatalities, the most glaring issue is that KVM fails to ensuretracing is disabled, and *stays* disabled prior to VM-Enter, which isnecessary as hardware disallows loading (the guest's) RTIT_CTL if tracingis enabled (enforced via a VMX consistency check). Per the SDM: If the logical processor is operating with Intel PT enabled (if IA32_RTIT_CTL.TraceEn = 1) at the time of VM entry, the "load IA32_RTIT_CTL" VM-entry control must be 0.On the host side, KVM doesn't validate the guest CPUID configurationprovided by userspace, and even worse, uses the guest configuration todecide what MSRs to save/load at VM-Enter and VM-Exit. E.g. configuringguest CPUID to enumerate more address ranges than are supported in hardwarewill result in KVM trying to passthrough, save, and load non-existent MSRs,which generates a variety of WARNs, ToPA ERRORs in the host, a potentialdeadlock, etc.

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

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

CVE-2024-53210 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:s390/iucv: MSG_PEEK causes memory leak in iucv_sock_destruct()Passing MSG_PEEK flag to skb_recv_datagram() increments skb refcount(skb->users) and iucv_sock_recvmsg() does not decrement skb refcountat exit.This results in skb memory leak in skb_queue_purge() and WARN_ON iniucv_sock_destruct() during socket close. To fix this decreaseskb refcount by one if MSG_PEEK is set in order to prevent memoryleak and WARN_ON.WARNING: CPU: 2 PID: 6292 at net/iucv/af_iucv.c:286 iucv_sock_destruct+0x144/0x1a0 [af_iucv]CPU: 2 PID: 6292 Comm: afiucv_test_msg Kdump: loaded Tainted: G W 6.10.0-rc7 #1Hardware name: IBM 3931 A01 704 (z/VM 7.3.0)Call Trace: [<001587c682c4aa98>] iucv_sock_destruct+0x148/0x1a0 [af_iucv] [<001587c682c4a9d0>] iucv_sock_destruct+0x80/0x1a0 [af_iucv] [<001587c704117a32>] __sk_destruct+0x52/0x550 [<001587c704104a54>] __sock_release+0xa4/0x230 [<001587c704104c0c>] sock_close+0x2c/0x40 [<001587c702c5f5a8>] __fput+0x2e8/0x970 [<001587c7024148c4>] task_work_run+0x1c4/0x2c0 [<001587c7023b0716>] do_exit+0x996/0x1050 [<001587c7023b13aa>] do_group_exit+0x13a/0x360 [<001587c7023b1626>] __s390x_sys_exit_group+0x56/0x60 [<001587c7022bccca>] do_syscall+0x27a/0x380 [<001587c7049a6a0c>] __do_syscall+0x9c/0x160 [<001587c7049ce8a8>] system_call+0x70/0x98 Last Breaking-Event-Address: [<001587c682c4a9d4>] iucv_sock_destruct+0x84/0x1a0 [af_iucv]

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---

CVE-2024-56581 Severity: Moderate CVSS3 score: 5.5

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Call free_htab_elem() after htab_unlock_bucket()For htab of maps, when the map is removed from the htab, it may hold thelast reference of the map. bpf_map_fd_put_ptr() will invokebpf_map_free_id() to free the id of the removed map element. However,bpf_map_fd_put_ptr() is invoked while holding a bucket lock(raw_spin_lock_t), and bpf_map_free_id() attempts to acquire map_idr_lock(spinlock_t), triggering the following lockdep warning: ============================= [ BUG: Invalid wait context ] 6.11.0-rc4+ #49 Not tainted ----------------------------- test_maps/4881 is trying to lock: ffffffff84884578 (map_idr_lock){+...}-{3:3}, at: bpf_map_free_id.part.0+0x21/0x70 other info that might help us debug this: context-{5:5} 2 locks held by test_maps/4881: #0: ffffffff846caf60 (rcu_read_lock){....}-{1:3}, at: bpf_fd_htab_map_update_elem+0xf9/0x270 #1: ffff888149ced148 (&htab->lockdep_key#2){....}-{2:2}, at: htab_map_update_elem+0x178/0xa80 stack backtrace: CPU: 0 UID: 0 PID: 4881 Comm: test_maps Not tainted 6.11.0-rc4+ #49 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), ...

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:mfd: intel_soc_pmic_bxtwc: Use IRQ domain for TMU deviceWhile design wise the idea of converting the driver to usethe hierarchy of the IRQ chips is correct, the implementationhas (inherited) flaws. This was unveiled when platform_get_irq()had started WARN() on IRQ 0 that is supposed to be a LinuxIRQ number (also known as vIRQ).Rework the driver to respect IRQ domain when creating each MFDdevice separately, as the domain is not the same for all of them.

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

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

CVE-2024-57889 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:pinctrl: mcp23s08: Fix sleeping in atomic context due to regmap lockingIf a device uses MCP23xxx IO expander to receive IRQs, the followingbug can happen: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:283 in_atomic(): 1, irqs_disabled(): 1, non_block: 0, ... preempt_count: 1, expected: 0 ... Call Trace: ... __might_resched+0x104/0x10e __might_sleep+0x3e/0x62 mutex_lock+0x20/0x4c regmap_lock_mutex+0x10/0x18 regmap_update_bits_base+0x2c/0x66 mcp23s08_irq_set_type+0x1ae/0x1d6 __irq_set_trigger+0x56/0x172 __setup_irq+0x1e6/0x646 request_threaded_irq+0xb6/0x160 ...We observed the problem while experimenting with a touchscreen driver whichused MCP23017 IO expander (I2C).The regmap in the pinctrl-mcp23s08 driver uses a mutex for protection fromconcurrent accesses, which is the default for regmaps without .fast_io,.disable_locking, etc.mcp23s08_irq_set_type() calls regmap_update_bits_base(), and the latterlocks the mutex.However, __setup_irq() locks desc->lock spinlock before calling thesefunctions. As a result, the system tries to lock the mutex whole holdingthe spinlock.It seems, the internal regmap locks are not needed in this driver at all.mcp->lock seems to protect the regmap from concurrent accesses already,except, probably, in mcp_pinconf_get/set.mcp23s08_irq_set_type() and mcp23s08_irq_mask/unmask() are called underchip_bus_lock(), which calls mcp23s08_irq_bus_lock(). The latter takesmcp->lock and enables regmap caching, so that the potentially slow I2Caccesses are deferred until chip_bus_unlock().The accesses to the regmap from mcp23s08_probe_one() do not need additionallocking.In all remaining places where the regmap is accessed, exceptmcp_pinconf_get/set(), the driver already takes mcp->lock.This patch adds locking in mcp_pinconf_get/set() and disables internallocking in the regmap config. Among other things, it fixes the sleepingin atomic context described above.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: flush delalloc workers queue before stopping cleaner kthread during unmountDuring the unmount path, at close_ctree(), we first stop the cleanerkthread, using kthread_stop() which frees the associated task_struct, andthen stop and destroy all the work queues. However after we stopped thecleaner we may still have a worker from the delalloc_workers queue runninginode.c:submit_compressed_extents(), which calls btrfs_add_delayed_iput(),which in turn tries to wake up the cleaner kthread - which was alreadydestroyed before, resulting in a use-after-free on the task_struct.Syzbot reported this with the following stack traces: BUG: KASAN: slab-use-after-free in __lock_acquire+0x78/0x2100 kernel/locking/lockdep.c:5089 Read of size 8 at addr ffff8880259d2818 by task kworker/u8:3/52 CPU: 1 UID: 0 PID: 52 Comm: kworker/u8:3 Not tainted 6.13.0-rc1-syzkaller-00002-gcdd30ebb1b9f #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 09/13/2024 Workqueue: btrfs-delalloc btrfs_work_helper Call Trace: __dump_stack lib/dump_stack.c:94 [inline] dump_stack_lvl+0x241/0x360 lib/dump_stack.c:120 print_address_description mm/kasan/report.c:378 [inline] print_report+0x169/0x550 mm/kasan/report.c:489 kasan_report+0x143/0x180 mm/kasan/report.c:602 __lock_acquire+0x78/0x2100 kernel/locking/lockdep.c:5089 lock_acquire+0x1ed/0x550 kernel/locking/lockdep.c:5849 __raw_spin_lock_irqsave include/linux/spinlock_api_smp.h:110 [inline] _raw_spin_lock_irqsave+0xd5/0x120 kernel/locking/spinlock.c:162 class_raw_spinlock_irqsave_constructor include/linux/spinlock.h:551 [inline] try_to_wake_up+0xc2/0x1470 kernel/sched/core.c:4205 submit_compressed_extents+0xdf/0x16e0 fs/btrfs/inode.c:1615 run_ordered_work fs/btrfs/async-thread.c:288 [inline] btrfs_work_helper+0x96f/0xc40 fs/btrfs/async-thread.c:324 process_one_work kernel/workqueue.c:3229 [inline] process_scheduled_works+0xa66/0x1840 kernel/workqueue.c:3310 worker_thread+0x870/0xd30 kernel/workqueue.c:3391 kthread+0x2f0/0x390 kernel/kthread.c:389 ret_from_fork+0x4b/0x80 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244 Allocated by task 2: kasan_save_stack mm/kasan/common.c:47 [inline] kasan_save_track+0x3f/0x80 mm/kasan/common.c:68 unpoison_slab_object mm/kasan/common.c:319 [inline] __kasan_slab_alloc+0x66/0x80 mm/kasan/common.c:345 kasan_slab_alloc include/linux/kasan.h:250 [inline] slab_post_alloc_hook mm/slub.c:4104 [inline] slab_alloc_node mm/slub.c:4153 [inline] kmem_cache_alloc_node_noprof+0x1d9/0x380 mm/slub.c:4205 alloc_task_struct_node kernel/fork.c:180 [inline] dup_task_struct+0x57/0x8c0 kernel/fork.c:1113 copy_process+0x5d1/0x3d50 kernel/fork.c:2225 kernel_clone+0x223/0x870 kernel/fork.c:2807 kernel_thread+0x1bc/0x240 kernel/fork.c:2869 create_kthread kernel/kthread.c:412 [inline] kthreadd+0x60d/0x810 kernel/kthread.c:767 ret_from_fork+0x4b/0x80 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244 Freed by task 24: kasan_save_stack mm/kasan/common.c:47 [inline] kasan_save_track+0x3f/0x80 mm/kasan/common.c:68 kasan_save_free_info+0x40/0x50 mm/kasan/generic.c:582 poison_slab_object mm/kasan/common.c:247 [inline] __kasan_slab_free+0x59/0x70 mm/kasan/common.c:264 kasan_slab_free include/linux/kasan.h:233 [inline] slab_free_hook mm/slub.c:2338 [inline] slab_free mm/slub.c:4598 [inline] kmem_cache_free+0x195/0x410 mm/slub.c:4700 put_task_struct include/linux/sched/task.h:144 [inline] delayed_put_task_struct+0x125/0x300 kernel/exit.c:227 rcu_do_batch kernel/rcu/tree.c:2567 [inline] rcu_core+0xaaa/0x17a0 kernel/rcu/tree.c:2823 handle_softirqs+0x2d4/0x9b0 kernel/softirq.c:554 run_ksoftirqd+0xca/0x130 kernel/softirq.c:943 ---truncated---

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

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

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

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

CVE-2024-58006 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: dwc: ep: Prevent changing BAR size/flags in pci_epc_set_bar()In commit 4284c88fff0e ("PCI: designware-ep: Allow pci_epc_set_bar() updateinbound map address") set_bar() was modified to support dynamicallychanging the backing physical address of a BAR that was already configured.This means that set_bar() can be called twice, without ever callingclear_bar() (as calling clear_bar() would clear the BAR's PCI addressassigned by the host).This can only be done if the new BAR size/flags does not differ from theexisting BAR configuration. Add these missing checks.If we allow set_bar() to set e.g. a new BAR size that differs from theexisting BAR size, the new address translation range will be smaller thanthe BAR size already determined by the host, which would mean that a readpast the new BAR size would pass the iATU untranslated, which could allowthe host to read memory not belonging to the new struct pci_epf_bar.While at it, add comments which clarifies the support for dynamicallychanging the physical address of a BAR. (Which was also missing.)

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_allocA NULL sock pointer is passed into l2cap_sock_alloc() when it is calledfrom l2cap_sock_new_connection_cb() and the error handling paths shouldalso be aware of it.Seemingly a more elegant solution would be to swap bt_sock_alloc() andl2cap_chan_create() calls since they are not interdependent to that momentbut then l2cap_chan_create() adds the soon to be deallocated and stilldummy-initialized channel to the global list accessible by many L2CAPpaths. The channel would be removed from the list in short period of timebut be a bit more straight-forward here and just check for NULL instead ofchanging the order of function calls.Found by Linux Verification Center (linuxtesting.org) with SVACE staticanalysis tool.

CVE-2024-58019 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:nvkm/gsp: correctly advance the read pointer of GSP message queueA GSP event message consists three parts: message header, RPC header,message body. GSP calculates the number of pages to write from thetotal size of a GSP message. This behavior can be observed from themovement of the write pointer.However, nvkm takes only the size of RPC header and message body asthe message size when advancing the read pointer. When handling atwo-page GSP message in the non rollback case, It wrongly takes themessage body of the previous message as the message header of the nextmessage. As the "message length" tends to be zero, in the calculation ofsize needs to be copied (0 - size of (message header)), the size needs tobe copied will be "0xffffffxx". It also triggers a kernel panic due to aNULL pointer error.[ 547.614102] msg: 00000f90: ff ff ff ff ff ff ff ff 40 d7 18 fb 8b 00 00 00 ........@.......[ 547.622533] msg: 00000fa0: 00 00 00 00 ff ff ff ff ff ff ff ff 00 00 00 00 ................[ 547.630965] msg: 00000fb0: ff ff ff ff ff ff ff ff 00 00 00 00 ff ff ff ff ................[ 547.639397] msg: 00000fc0: ff ff ff ff 00 00 00 00 ff ff ff ff ff ff ff ff ................[ 547.647832] nvkm 0000:c1:00.0: gsp: peek msg rpc fn:0 len:0x0/0xffffffffffffffe0[ 547.655225] nvkm 0000:c1:00.0: gsp: get msg rpc fn:0 len:0x0/0xffffffffffffffe0[ 547.662532] BUG: kernel NULL pointer dereference, address: 0000000000000020[ 547.669485] #PF: supervisor read access in kernel mode[ 547.674624] #PF: error_code(0x0000) - not-present page[ 547.679755] PGD 0 P4D 0[ 547.682294] Oops: 0000 [#1] PREEMPT SMP NOPTI[ 547.686643] CPU: 22 PID: 322 Comm: kworker/22:1 Tainted: G E 6.9.0-rc6+ #1[ 547.694893] Hardware name: ASRockRack 1U1G-MILAN/N/ROMED8-NL, BIOS L3.12E 09/06/2022[ 547.702626] Workqueue: events r535_gsp_msgq_work [nvkm][ 547.707921] RIP: 0010:r535_gsp_msg_recv+0x87/0x230 [nvkm][ 547.713375] Code: 00 8b 70 08 48 89 e1 31 d2 4c 89 f7 e8 12 f5 ff ff 48 89 c5 48 85 c0 0f 84 cf 00 00 00 48 81 fd 00 f0 ff ff 0f 87 c4 00 00 00 <8b> 55 10 41 8b 46 30 85 d2 0f 85 f6 00 00 00 83 f8 04 76 10 ba 05[ 547.732119] RSP: 0018:ffffabe440f87e10 EFLAGS: 00010203[ 547.737335] RAX: 0000000000000010 RBX: 0000000000000008 RCX: 000000000000003f[ 547.744461] RDX: 0000000000000000 RSI: ffffabe4480a8030 RDI: 0000000000000010[ 547.751585] RBP: 0000000000000010 R08: 0000000000000000 R09: ffffabe440f87bb0[ 547.758707] R10: ffffabe440f87dc8 R11: 0000000000000010 R12: 0000000000000000[ 547.765834] R13: 0000000000000000 R14: ffff9351df1e5000 R15: 0000000000000000[ 547.772958] FS: 0000000000000000(0000) GS:ffff93708eb00000(0000) knlGS:0000000000000000[ 547.781035] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 547.786771] CR2: 0000000000000020 CR3: 00000003cc220002 CR4: 0000000000770ef0[ 547.793896] PKRU: 55555554[ 547.796600] Call Trace:[ 547.799046] [ 547.801152] ? __die+0x20/0x70[ 547.804211] ? page_fault_oops+0x75/0x170[ 547.808221] ? print_hex_dump+0x100/0x160[ 547.812226] ? exc_page_fault+0x64/0x150[ 547.816152] ? asm_exc_page_fault+0x22/0x30[ 547.820341] ? r535_gsp_msg_recv+0x87/0x230 [nvkm][ 547.825184] r535_gsp_msgq_work+0x42/0x50 [nvkm][ 547.829845] process_one_work+0x196/0x3d0[ 547.833861] worker_thread+0x2fc/0x410[ 547.837613] ? __pfx_worker_thread+0x10/0x10[ 547.841885] kthread+0xdf/0x110[ 547.845031] ? __pfx_kthread+0x10/0x10[ 547.848775] ret_from_fork+0x30/0x50[ 547.852354] ? __pfx_kthread+0x10/0x10[ 547.856097] ret_from_fork_asm+0x1a/0x30[ 547.860019] [ 547.862208] Modules linked in: nvkm(E) gsp_log(E) snd_seq_dummy(E) snd_hrtimer(E) snd_seq(E) snd_timer(E) snd_seq_device(E) snd(E) soundcore(E) rfkill(E) qrtr(E) vfat(E) fat(E) ipmi_ssif(E) amd_atl(E) intel_rapl_msr(E) intel_rapl_common(E) amd64_edac(E) mlx5_ib(E) edac_mce_amd(E) kvm_amd---truncated---

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

CVE-2024-58083 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: Explicitly verify target vCPU is online in kvm_get_vcpu()Explicitly verify the target vCPU is fully online _prior_ to clamping theindex in kvm_get_vcpu(). If the index is "bad", the nospec clamping willgenerate '0', i.e. KVM will return vCPU0 instead of NULL.In practice, the bug is unlikely to cause problems, as it will only comeinto play if userspace or the guest is buggy or misbehaving, e.g. KVM maysend interrupts to vCPU0 instead of dropping them on the floor.However, returning vCPU0 when it shouldn't exist per online_vcpus isproblematic now that KVM uses an xarray for the vCPUs array, as KVM needsto insert into the xarray before publishing the vCPU to userspace (seecommit c5b077549136 ("KVM: Convert the kvm->vcpus array to a xarray")),i.e. before vCPU creation is guaranteed to succeed.As a result, incorrectly providing access to vCPU0 will trigger ause-after-free if vCPU0 is dereferenced and kvm_vm_ioctl_create_vcpu()bails out of vCPU creation due to an error and frees vCPU0. Commitafb2acb2e3a3 ("KVM: Fix vcpu_array[0] races") papered over that issue, butin doing so introduced an unsolvable teardown conundrum. Preventingaccesses to vCPU0 before it's fully online will allow reverting commitafb2acb2e3a3, without re-introducing the vcpu_array[0] UAF race.

Furtherinstrumentation revealed that in the interrupt disabled section of kexecjump one of the syscore_suspend() callbacks woke up a task, which set theNEED_RESCHED flag. A later callback in the resume path invokedcond_resched() which in turn led to the invocation of the scheduler: __cond_resched+0x21/0x60 down_timeout+0x18/0x60 acpi_os_wait_semaphore+0x4c/0x80 acpi_ut_acquire_mutex+0x3d/0x100 acpi_ns_get_node+0x27/0x60 acpi_ns_evaluate+0x1cb/0x2d0 acpi_rs_set_srs_method_data+0x156/0x190 acpi_pci_link_set+0x11c/0x290 irqrouter_resume+0x54/0x60 syscore_resume+0x6a/0x200 kernel_kexec+0x145/0x1c0 __do_sys_reboot+0xeb/0x240 do_syscall_64+0x95/0x180This is a long standing problem, which probably got more visible withthe recent printk changes. Something does a task wakeup and thescheduler sets the NEED_RESCHED flag. cond_resched() sees it set andinvokes schedule() from a completely bogus context. The schedulerenables interrupts after context switching, which causes the abovewarning at the end.Quite some of the code paths in syscore_suspend()/resume() can result intriggering a wakeup with the exactly same consequences. They might nothave done so yet, but as they share a lot of code with normal operationsit's just a question of time.The problem only affects the PREEMPT_NONE and PREEMPT_VOLUNTARY schedulingmodels. Full preemption is not affected as cond_resched() is disabled andthe preemption check preemptible() takes the interrupt disabled flag intoaccount.Cure the problem by adding a corresponding check into cond_resched().

Allocate a shadow buffer for driversthat require deferred I/O and use it as framebuffer memory.Fixes driver errors about being "Unable to handle kernel NULL pointerdereference at virtual address" or "Unable to handle kernel pagingrequest at virtual address".The patch splits drm_fbdev_dma_driver_fbdev_probe() in an initialallocation, which creates the DMA-backed buffer object, and a tailthat sets up the fbdev data structures. There is a tail function fordirect memory mappings and a tail function for deferred I/O withthe shadow buffer.It is no longer possible to use deferred I/O without shadow buffer.It can be re-added if there exists a reliably test for usable structpage in the allocated DMA-backed buffer object.

If function 0 is removed before sibling function,link->downstream would point to free'd memory after.After above change, we freed the ASPM parent link state upon any functionremoval on the bus pertaining to a given link.That is too early. If the link is to a PCIe switch with MFD on the upstreamport, then removing functions other than 0 first would free a link whichstill remains parent_link to the remaining downstream ports.The resulting GPFs are especially frequent during hot-unplug, becausepciehp removes devices on the link bus in reverse order.On that switch, function 0 is the virtual P2P bridge to the internal bus.Free exactly when function 0 is removed -- before the parent link isobsolete, but after all subordinate links are gone.[kwilczynski: commit log]

Description: In the Linux kernel, the following vulnerability has been resolved:afs: Fix the maximum cell name lengthThe kafs filesystem limits the maximum length of a cell to 256 bytes, but aproblem occurs if someone actually does that: kafs tries to create adirectory under /proc/net/afs/ with the name of the cell, but that failswith a warning: WARNING: CPU: 0 PID: 9 at fs/proc/generic.c:405because procfs limits the maximum filename length to 255.However, the DNS limits the maximum lookup length and, by extension, themaximum cell name, to 255 less two (length count and trailing NUL).Fix this by limiting the maximum acceptable cellname length to 253. Thisalso allows us to be sure we can create the "/afs/./" mountpoint too.Further, split the YFS VL record cell name maximum to be the 256 allowed bythe protocol and ignore the record retrieved by YFSVL.GetCellName if itexceeds 253.

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

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

CVE-2025-21732 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/mlx5: Fix a race for an ODP MR which leads to CQE with errorThis patch addresses a race condition for an ODP MR that can result in aCQE with an error on the UMR QP.During the __mlx5_ib_dereg_mr() flow, the following sequence of callsoccurs:mlx5_revoke_mr() mlx5r_umr_revoke_mr() mlx5r_umr_post_send_wait()At this point, the lkey is freed from the hardware's perspective.However, concurrently, mlx5_ib_invalidate_range() might be triggered byanother task attempting to invalidate a range for the same freed lkey.This task will: - Acquire the umem_odp->umem_mutex lock. - Call mlx5r_umr_update_xlt() on the UMR QP. - Since the lkey has already been freed, this can lead to a CQE error, causing the UMR QP to enter an error state [1].To resolve this race condition, the umem_odp->umem_mutex lock is now alsoacquired as part of the mlx5_revoke_mr() scope. Upon successful revoke,we set umem_odp->private which points to that MR to NULL, preventing anyfurther invalidation attempts on its lkey.[1] From dmesg: infiniband rocep8s0f0: dump_cqe:277:(pid 0): WC error: 6, Message: memory bind operation error cqe_dump: 00000000: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 cqe_dump: 00000010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 cqe_dump: 00000020: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 cqe_dump: 00000030: 00 00 00 00 08 00 78 06 25 00 11 b9 00 0e dd d2 WARNING: CPU: 15 PID: 1506 at drivers/infiniband/hw/mlx5/umr.c:394 mlx5r_umr_post_send_wait+0x15a/0x2b0 [mlx5_ib] Modules linked in: ip6table_mangle ip6table_natip6table_filter ip6_tables iptable_mangle xt_conntrack xt_MASQUERADE nf_conntrack_netlink nfnetlink xt_addrtype iptable_nat nf_nat br_netfilter rpcsec_gss_krb5 auth_rpcgss oid_registry overlay rpcrdma rdma_ucm ib_iser libiscsi scsi_transport_iscsi rdma_cm iw_cm ib_umad ib_ipoib ib_cm mlx5_ib ib_uverbs ib_core fuse mlx5_core CPU: 15 UID: 0 PID: 1506 Comm: ibv_rc_pingpong Not tainted 6.12.0-rc7+ #1626 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014 RIP: 0010:mlx5r_umr_post_send_wait+0x15a/0x2b0 [mlx5_ib] [..] Call Trace: mlx5r_umr_update_xlt+0x23c/0x3e0 [mlx5_ib] mlx5_ib_invalidate_range+0x2e1/0x330 [mlx5_ib] __mmu_notifier_invalidate_range_start+0x1e1/0x240 zap_page_range_single+0xf1/0x1a0 madvise_vma_behavior+0x677/0x6e0 do_madvise+0x1a2/0x4b0 __x64_sys_madvise+0x25/0x30 do_syscall_64+0x6b/0x140 entry_SYSCALL_64_after_hwframe+0x76/0x7e

Description: In the Linux kernel, the following vulnerability has been resolved:tracing/osnoise: Fix resetting of tracepointsIf a timerlat tracer is started with the osnoise option OSNOISE_WORKLOADdisabled, but then that option is enabled and timerlat is removed, thetracepoints that were enabled on timerlat registration do not getdisabled. If the option is disabled again and timelat is started, then ittriggers a warning in the tracepoint code due to registering thetracepoint again without ever disabling it.Do not use the same user space defined options to know to disable thetracepoints when timerlat is removed. Instead, set a global flag when itis enabled and use that flag to know to disable the events. ~# echo NO_OSNOISE_WORKLOAD > /sys/kernel/tracing/osnoise/options ~# echo timerlat > /sys/kernel/tracing/current_tracer ~# echo OSNOISE_WORKLOAD > /sys/kernel/tracing/osnoise/options ~# echo nop > /sys/kernel/tracing/current_tracer ~# echo NO_OSNOISE_WORKLOAD > /sys/kernel/tracing/osnoise/options ~# echo timerlat > /sys/kernel/tracing/current_tracerTriggers: ------------[ cut here ]------------ WARNING: CPU: 6 PID: 1337 at kernel/tracepoint.c:294 tracepoint_add_func+0x3b6/0x3f0 Modules linked in: CPU: 6 UID: 0 PID: 1337 Comm: rtla Not tainted 6.13.0-rc4-test-00018-ga867c441128e-dirty #73 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2 04/01/2014 RIP: 0010:tracepoint_add_func+0x3b6/0x3f0 Code: 48 8b 53 28 48 8b 73 20 4c 89 04 24 e8 23 59 11 00 4c 8b 04 24 e9 36 fe ff ff 0f 0b b8 ea ff ff ff 45 84 e4 0f 84 68 fe ff ff <0f> 0b e9 61 fe ff ff 48 8b 7b 18 48 85 ff 0f 84 4f ff ff ff 49 8b RSP: 0018:ffffb9b003a87ca0 EFLAGS: 00010202 RAX: 00000000ffffffef RBX: ffffffff92f30860 RCX: 0000000000000000 RDX: 0000000000000000 RSI: ffff9bf59e91ccd0 RDI: ffffffff913b6410 RBP: 000000000000000a R08: 00000000000005c7 R09: 0000000000000002 R10: ffffb9b003a87ce0 R11: 0000000000000002 R12: 0000000000000001 R13: ffffb9b003a87ce0 R14: ffffffffffffffef R15: 0000000000000008 FS: 00007fce81209240(0000) GS:ffff9bf6fdd00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000055e99b728000 CR3: 00000001277c0002 CR4: 0000000000172ef0 Call Trace: ? __warn.cold+0xb7/0x14d ? tracepoint_add_func+0x3b6/0x3f0 ? report_bug+0xea/0x170 ? handle_bug+0x58/0x90 ? exc_invalid_op+0x17/0x70 ? asm_exc_invalid_op+0x1a/0x20 ? __pfx_trace_sched_migrate_callback+0x10/0x10 ? tracepoint_add_func+0x3b6/0x3f0 ? __pfx_trace_sched_migrate_callback+0x10/0x10 ? __pfx_trace_sched_migrate_callback+0x10/0x10 tracepoint_probe_register+0x78/0xb0 ? __pfx_trace_sched_migrate_callback+0x10/0x10 osnoise_workload_start+0x2b5/0x370 timerlat_tracer_init+0x76/0x1b0 tracing_set_tracer+0x244/0x400 tracing_set_trace_write+0xa0/0xe0 vfs_write+0xfc/0x570 ? do_sys_openat2+0x9c/0xe0 ksys_write+0x72/0xf0 do_syscall_64+0x79/0x1c0 entry_SYSCALL_64_after_hwframe+0x76/0x7e

CVE-2025-21742 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:usbnet: ipheth: use static NDP16 location in URBOriginal code allowed for the start of NDP16 to be anywhere within theURB based on the `wNdpIndex` value in NTH16. Only the start position ofNDP16 was checked, so it was possible for even the fixed-length partof NDP16 to extend past the end of URB, leading to an out-of-boundsread.On iOS devices, the NDP16 header always directly follows NTH16. Rely onand check for this specific format.This, along with NCM-specific minimal URB length check that alreadyexists, will ensure that the fixed-length part of NDP16 plus a setamount of DPEs fit within the URB.Note that this commit alone does not fully address the OoB read.The limit on the amount of DPEs needs to be enforced separately.

The error willbe the error that resulted in the transaction abort or -EIO if notransaction abort happened.This was recently reported by syzbot with the following trace: FAULT_INJECTION: forcing a failure. name failslab, interval 1, probability 0, space 0, times 1 CPU: 0 UID: 0 PID: 5321 Comm: syz.0.0 Not tainted 6.13.0-rc5-syzkaller #0 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2~bpo12+1 04/01/2014 Call Trace: __dump_stack lib/dump_stack.c:94 [inline] dump_stack_lvl+0x241/0x360 lib/dump_stack.c:120 fail_dump lib/fault-inject.c:53 [inline] should_fail_ex+0x3b0/0x4e0 lib/fault-inject.c:154 should_failslab+0xac/0x100 mm/failslab.c:46 slab_pre_alloc_hook mm/slub.c:4072 [inline] slab_alloc_node mm/slub.c:4148 [inline] __do_kmalloc_node mm/slub.c:4297 [inline] __kmalloc_noprof+0xdd/0x4c0 mm/slub.c:4310 kmalloc_noprof include/linux/slab.h:905 [inline] kzalloc_noprof include/linux/slab.h:1037 [inline] btrfs_chunk_alloc_add_chunk_item+0x244/0x1100 fs/btrfs/volumes.c:5742 reserve_chunk_space+0x1ca/0x2c0 fs/btrfs/block-group.c:4292 check_system_chunk fs/btrfs/block-group.c:4319 [inline] do_chunk_alloc fs/btrfs/block-group.c:3891 [inline] btrfs_chunk_alloc+0x77b/0xf80 fs/btrfs/block-group.c:4187 find_free_extent_update_loop fs/btrfs/extent-tree.c:4166 [inline] find_free_extent+0x42d1/0x5810 fs/btrfs/extent-tree.c:4579 btrfs_reserve_extent+0x422/0x810 fs/btrfs/extent-tree.c:4672 btrfs_new_extent_direct fs/btrfs/direct-io.c:186 [inline] btrfs_get_blocks_direct_write+0x706/0xfa0 fs/btrfs/direct-io.c:321 btrfs_dio_iomap_begin+0xbb7/0x1180 fs/btrfs/direct-io.c:525 iomap_iter+0x697/0xf60 fs/iomap/iter.c:90 __iomap_dio_rw+0xeb9/0x25b0 fs/iomap/direct-io.c:702 btrfs_dio_write fs/btrfs/direct-io.c:775 [inline] btrfs_direct_write+0x610/0xa30 fs/btrfs/direct-io.c:880 btrfs_do_write_iter+0x2a0/0x760 fs/btrfs/file.c:1397 do_iter_readv_writev+0x600/0x880 vfs_writev+0x376/0xba0 fs/read_write.c:1050 do_pwritev fs/read_write.c:1146 [inline] __do_sys_pwritev2 fs/read_write.c:1204 [inline] __se_sys_pwritev2+0x196/0x2b0 fs/read_write.c:1195 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xf3/0x230 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7f RIP: 0033:0x7f1281f85d29 RSP: 002b:00007f12819fe038 EFLAGS: 00000246 ORIG_RAX: 0000000000000148 RAX: ffffffffffffffda RBX: 00007f1282176080 RCX: 00007f1281f85d29 RDX: 0000000000000001 RSI: 0000000020000240 RDI: 0000000000000005 RBP: 00007f12819fe090 R08: 0000000000000000 R09: 0000000000000003 R10: 0000000000007000 R11: 0000000000000246 R12: 0000000000000002 R13: 0000000000000000 R14: 00007f1282176080 R15: 00007ffcb9e23328 BTRFS error (device loop0 state A): Transaction aborted (error -12) BTRFS: error (device loop0 state A---truncated---

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

Description: In the Linux kernel, the following vulnerability has been resolved:iommu: Fix potential memory leak in iopf_queue_remove_device()The iopf_queue_remove_device() helper removes a device from the per-iommuiopf queue when PRI is disabled on the device. It responds to alloutstanding iopf's with an IOMMU_PAGE_RESP_INVALID code and detaches thedevice from the queue.However, it fails to release the group structure that represents a groupof iopf's awaiting for a response after responding to the hardware. Thiscan cause a memory leak if iopf_queue_remove_device() is called withpending iopf's.Fix it by calling iopf_free_group() after the iopf group is responded.

CVE-2025-21771 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:sched_ext: Fix incorrect autogroup migration detectionscx_move_task() is called from sched_move_task() and tells the BPF schedulerthat cgroup migration is being committed. sched_move_task() is used by bothcgroup and autogroup migrations and scx_move_task() tried to filter outautogroup migrations by testing the destination cgroup and PF_EXITING butthis is not enough. In fact, without explicitly tagging the thread which isdoing the cgroup migration, there is no good way to tell apartscx_move_task() invocations for racing migration to the root cgroup and anautogroup migration.This led to scx_move_task() incorrectly ignoring a migration from non-rootcgroup to an autogroup of the root cgroup triggering the following warning: WARNING: CPU: 7 PID: 1 at kernel/sched/ext.c:3725 scx_cgroup_can_attach+0x196/0x340 ...

CVE-2025-21777 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ring-buffer: Validate the persistent meta data subbuf arrayThe meta data for a mapped ring buffer contains an array of indexes of allthe subbuffers. The first entry is the reader page, and the rest of theentries lay out the order of the subbuffers in how the ring buffer linklist is to be created.The validator currently makes sure that all the entries are within therange of 0 and nr_subbufs. But it does not check if there are anyduplicates.While working on the ring buffer, I corrupted this array, where I addedduplicates. The validator did not catch it and created the ring bufferlink list on top of it. Luckily, the corruption was only that the readerpage was also in the writer path and only presented corrupted data but didnot crash the kernel. But if there were duplicates in the writer side,then it could corrupt the ring buffer link list and cause a crash.Create a bitmask array with the size of the number of subbuffers. Thenclear it. When walking through the subbuf array checking to see if theentries are within the range, test if its bit is already set in thesubbuf_mask. If it is, then there is duplicates and fail the validation.If not, set the corresponding bit and continue.

It is rather trivial to allow this, but fornow just disable mmap() of instances that have their ring buffer from thereserve_mem option.If an mmap() is performed on a persistent buffer it will return -ENODEVjust like it would if the .mmap field wasn't defined in thefile_operations structure.

CVE-2025-21813 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:timers/migration: Fix off-by-one root mis-connectionBefore attaching a new root to the old root, the children counter of thenew root is checked to verify that only the upcoming CPU's top group havebeen connected to it. However since the recently added commit b729cc1ec21a("timers/migration: Fix another race between hotplug and idle entry/exit")this check is not valid anymore because the old root is pre-accountedas a child to the new root. Therefore after connecting the upcomingCPU's top group to the new root, the children count to be expected mustbe 2 and not 1 anymore.This omission results in the old root to not be connected to the newroot. Then eventually the system may run with more than one top level,which defeats the purpose of a single idle migrator.Also the old root is pre-accounted but not connected upon the new rootcreation.

Depending on several considerations (crystal ball power managementbased election, earliest timer already enqueued, timer migration enabled ornot), the target may eventually be the current CPU even if offline.

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:seccomp: passthrough uretprobe systemcall without filteringWhen attaching uretprobes to processes running inside docker, the attachedprocess is segfaulted when encountering the retprobe.The reason is that now that uretprobe is a system call the default seccompfilters in docker block it as they only allow a specific set of knownsyscalls. This is true for other userspace applications which use seccompto control their syscall surface.Since uretprobe is a "kernel implementation detail" system call which isnot used by userspace application code directly, it is impractical andthere's very little point in forcing all userspace applications toexplicitly allow it in order to avoid crashing tracked processes.Pass this systemcall through seccomp without depending on configuration.Note: uretprobe is currently only x86_64 and isn't expected to ever besupported in i386.[kees: minimized changes for easier backporting, tweaked commit log]

Description: In the Linux kernel, the following vulnerability has been resolved:thermal/netlink: Prevent userspace segmentation fault by adjusting UAPI headerThe intel-lpmd tool [1], which uses the THERMAL_GENL_ATTR_CPU_CAPABILITYattribute to receive HFI events from kernel space, encounters asegmentation fault after commit 1773572863c4 ("thermal: netlink: Add thecommands and the events for the thresholds").The issue arises because the THERMAL_GENL_ATTR_CPU_CAPABILITY raw valuewas changed while intel_lpmd still uses the old value.Although intel_lpmd can be updated to check the THERMAL_GENL_VERSION anduse the appropriate THERMAL_GENL_ATTR_CPU_CAPABILITY value, the commititself is questionable.The commit introduced a new element in the middle of enum thermal_genl_attr,which affects many existing attributes and introduces potential risksand unnecessary maintenance burdens for userspace thermal netlink eventusers.Solve the issue by moving the newly introducedTHERMAL_GENL_ATTR_TZ_PREV_TEMP attribute to the end of theenum thermal_genl_attr.

CVE-2025-21846 Severity: Moderate CVSS3 score: 5.5

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

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

CVE-2025-21854 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:sockmap, vsock: For connectible sockets allow only connectedsockmap expects all vsocks to have a transport assigned, which is expressedin vsock_proto::psock_update_sk_prot(). However, there is an edge casewhere an unconnected (connectible) socket may lose its previously assignedtransport. This is handled with a NULL check in the vsock/BPF recv path.Another design detail is that listening vsocks are not supposed to have anytransport assigned at all. Which implies they are not supported by thesockmap. But this is complicated by the fact that a socket, beforeswitching to TCP_LISTEN, may have had some transport assigned during afailed connect() attempt. Hence, we may end up with a listening vsock in asockmap, which blows up quickly:KASAN: null-ptr-deref in range [0x0000000000000120-0x0000000000000127]CPU: 7 UID: 0 PID: 56 Comm: kworker/7:0 Not tainted 6.14.0-rc1+Workqueue: vsock-loopback vsock_loopback_workRIP: 0010:vsock_read_skb+0x4b/0x90Call Trace: sk_psock_verdict_data_ready+0xa4/0x2e0 virtio_transport_recv_pkt+0x1ca8/0x2acc vsock_loopback_work+0x27d/0x3f0 process_one_work+0x846/0x1420 worker_thread+0x5b3/0xf80 kthread+0x35a/0x700 ret_from_fork+0x2d/0x70 ret_from_fork_asm+0x1a/0x30For connectible sockets, instead of relying solely on the state ofvsk->transport, tell sockmap to only allow those representing establishedconnections.

When freeing zswapentries for those pages, zswap_entry_free() uncharges the zswap entriesthat were not previously charged, causing zswap charging to becomeinconsistent.This inconsistency triggers two warnings with following steps: # On a machine with 64GiB of RAM and 36GiB of zswap $ stress-ng --bigheap 2 # wait until the OOM-killer kills stress-ng $ sudo reboot The two warnings are: in mm/memcontrol.c:163, function obj_cgroup_release(): WARN_ON_ONCE(nr_bytes & (PAGE_SIZE - 1)); in mm/page_counter.c:60, function page_counter_cancel(): if (WARN_ONCE(new < 0, "page_counter underflow: %ld nr_pages=%lu\n", new, nr_pages))zswap_stored_pages also becomes inconsistent in the same way.As suggested by Kanchana, increment zswap_stored_pages and charge zswapentries within zswap_store_page() when it succeeds. This way,zswap_entry_free() will decrement the counter and uncharge the entrieswhen it failed to zswap the entire folio.While this could potentially be optimized by batching objcg charging andincrementing the counter, let's focus on fixing the bug this time andleave the optimization for later after some evaluation.After resolving the inconsistency, the warnings disappear.[42.hyeyoo@gmail.com: refactor zswap_store_page()]

Description: In the Linux kernel, the following vulnerability has been resolved:mm/migrate_device: don't add folio to be freed to LRU in migrate_device_finalize()If migration succeeded, we calledfolio_migrate_flags()->mem_cgroup_migrate() to migrate the memcg from theold to the new folio. This will set memcg_data of the old folio to 0.Similarly, if migration failed, memcg_data of the dst folio is left unset.If we call folio_putback_lru() on such folios (memcg_data == 0), we willadd the folio to be freed to the LRU, making memcg code unhappy.

CVE-2025-21864 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:tcp: drop secpath at the same time as we currently drop dstXiumei reported hitting the WARN in xfrm6_tunnel_net_exit whilerunning tests that boil down to: - create a pair of netns - run a basic TCP test over ipcomp6 - delete the pair of netnsThe xfrm_state found on spi_byaddr was not deleted at the time wedelete the netns, because we still have a reference on it. Thislingering reference comes from a secpath (which holds a ref on thexfrm_state), which is still attached to an skb. This skb is notleaked, it ends up on sk_receive_queue and then gets defer-free'd byskb_attempt_defer_free.The problem happens when we defer freeing an skb (push it on one CPU'sdefer_list), and don't flush that list before the netns is deleted. Inthat case, we still have a reference on the xfrm_state that we don'texpect at this point.We already drop the skb's dst in the TCP receive path when it's nolonger needed, so let's also drop the secpath. At this point,tcp_filter has already called into the LSM hooks that may require thesecpath, so it should not be needed anymore. However, in some of thoseplaces, the MPTCP extension has just been attached to the skb, so wecannot simply drop all extensions.

CVE-2025-21865 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:gtp: Suppress list corruption splat in gtp_net_exit_batch_rtnl().Brad Spengler reported the list_del() corruption splat ingtp_net_exit_batch_rtnl(). [0]Commit eb28fd76c0a0 ("gtp: Destroy device along with udp socket's netnsdismantle.") added the for_each_netdev() loop in gtp_net_exit_batch_rtnl()to destroy devices in each netns as done in geneve and ip tunnels.However, this could trigger ->dellink() twice for the same device during->exit_batch_rtnl().Say we have two netns A & B and gtp device B that resides in netns B butwhose UDP socket is in netns A. 1. cleanup_net() processes netns A and then B. 2. gtp_net_exit_batch_rtnl() finds the device B while iterating netns A's gn->gtp_dev_list and calls ->dellink(). [ device B is not yet unlinked from netns B as unregister_netdevice_many() has not been called. ] 3. gtp_net_exit_batch_rtnl() finds the device B while iterating netns B's for_each_netdev() and calls ->dellink().gtp_dellink() cleans up the device's hash table, unlinks the dev fromgn->gtp_dev_list, and calls unregister_netdevice_queue().Basically, calling gtp_dellink() multiple times is fine unlessCONFIG_DEBUG_LIST is enabled.Let's remove for_each_netdev() in gtp_net_exit_batch_rtnl() anddelegate the destruction to default_device_exit_batch() as donein bareudp.[0]:list_del corruption, ffff8880aaa62c00->next (autoslab_size_M_dev_P_net_core_dev_11127_8_1328_8_S_4096_A_64_n_139+0xc00/0x1000 [slab object]) is LIST_POISON1 (ffffffffffffff02) (prev is 0xffffffffffffff04)kernel BUG at lib/list_debug.c:58!Oops: invalid opcode: 0000 [#1] PREEMPT SMP KASANCPU: 1 UID: 0 PID: 1804 Comm: kworker/u8:7 Tainted: G T 6.12.13-grsec-full-20250211091339 #1Tainted: [T]=RANDSTRUCTHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014Workqueue: netns cleanup_netRIP: 0010:[] __list_del_entry_valid_or_report+0x141/0x200 lib/list_debug.c:58Code: c2 76 91 31 c0 e8 9f b1 f7 fc 0f 0b 4d 89 f0 48 c7 c1 02 ff ff ff 48 89 ea 48 89 ee 48 c7 c7 e0 c2 76 91 31 c0 e8 7f b1 f7 fc <0f> 0b 4d 89 e8 48 c7 c1 04 ff ff ff 48 89 ea 48 89 ee 48 c7 c7 60RSP: 0018:fffffe8040b4fbd0 EFLAGS: 00010283RAX: 00000000000000cc RBX: dffffc0000000000 RCX: ffffffff818c4054RDX: ffffffff84947381 RSI: ffffffff818d1512 RDI: 0000000000000000RBP: ffff8880aaa62c00 R08: 0000000000000001 R09: fffffbd008169f32R10: fffffe8040b4f997 R11: 0000000000000001 R12: a1988d84f24943e4R13: ffffffffffffff02 R14: ffffffffffffff04 R15: ffff8880aaa62c08RBX: kasan shadow of 0x0RCX: __wake_up_klogd.part.0+0x74/0xe0 kernel/printk/printk.c:4554RDX: __list_del_entry_valid_or_report+0x141/0x200 lib/list_debug.c:58RSI: vprintk+0x72/0x100 kernel/printk/printk_safe.c:71RBP: autoslab_size_M_dev_P_net_core_dev_11127_8_1328_8_S_4096_A_64_n_139+0xc00/0x1000 [slab object]RSP: process kstack fffffe8040b4fbd0+0x7bd0/0x8000 [kworker/u8:7+netns 1804 ]R09: kasan shadow of process kstack fffffe8040b4f990+0x7990/0x8000 [kworker/u8:7+netns 1804 ]R10: process kstack fffffe8040b4f997+0x7997/0x8000 [kworker/u8:7+netns 1804 ]R15: autoslab_size_M_dev_P_net_core_dev_11127_8_1328_8_S_4096_A_64_n_139+0xc08/0x1000 [slab object]FS: 0000000000000000(0000) GS:ffff888116000000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 0000748f5372c000 CR3: 0000000015408000 CR4: 00000000003406f0 shadow CR4: 00000000003406f0Stack: 0000000000000000 ffffffff8a0c35e7 ffffffff8a0c3603 ffff8880aaa62c00 ffff8880aaa62c00 0000000000000004 ffff88811145311c 0000000000000005 0000000000000001 ffff8880aaa62000 fffffe8040b4fd40 ffffffff8a0c360dCall Trace: [] __list_del_entry_valid include/linux/list.h:131 [inline] fffffe8040b4fc28 [] __list_del_entry include/linux/list.h:248 [inline] fffffe8040b4fc28 [] list_del include/linux/list.h:262 [inl---truncated---

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

Description: In the Linux kernel, the following vulnerability has been resolved:bpf, test_run: Fix use-after-free issue in eth_skb_pkt_type()KMSAN reported a use-after-free issue in eth_skb_pkt_type()[1]. Thecause of the issue was that eth_skb_pkt_type() accessed skb's datathat didn't contain an Ethernet header. This occurs whenbpf_prog_test_run_xdp() passes an invalid value as the user_dataargument to bpf_test_init().Fix this by returning an error when user_data is less than ETH_HLEN inbpf_test_init(). Additionally, remove the check for "if (user_size >size)" as it is unnecessary.[1]BUG: KMSAN: use-after-free in eth_skb_pkt_type include/linux/etherdevice.h:627 [inline]BUG: KMSAN: use-after-free in eth_type_trans+0x4ee/0x980 net/ethernet/eth.c:165 eth_skb_pkt_type include/linux/etherdevice.h:627 [inline] eth_type_trans+0x4ee/0x980 net/ethernet/eth.c:165 __xdp_build_skb_from_frame+0x5a8/0xa50 net/core/xdp.c:635 xdp_recv_frames net/bpf/test_run.c:272 [inline] xdp_test_run_batch net/bpf/test_run.c:361 [inline] bpf_test_run_xdp_live+0x2954/0x3330 net/bpf/test_run.c:390 bpf_prog_test_run_xdp+0x148e/0x1b10 net/bpf/test_run.c:1318 bpf_prog_test_run+0x5b7/0xa30 kernel/bpf/syscall.c:4371 __sys_bpf+0x6a6/0xe20 kernel/bpf/syscall.c:5777 __do_sys_bpf kernel/bpf/syscall.c:5866 [inline] __se_sys_bpf kernel/bpf/syscall.c:5864 [inline] __x64_sys_bpf+0xa4/0xf0 kernel/bpf/syscall.c:5864 x64_sys_call+0x2ea0/0x3d90 arch/x86/include/generated/asm/syscalls_64.h:322 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xd9/0x1d0 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7fUninit was created at: free_pages_prepare mm/page_alloc.c:1056 [inline] free_unref_page+0x156/0x1320 mm/page_alloc.c:2657 __free_pages+0xa3/0x1b0 mm/page_alloc.c:4838 bpf_ringbuf_free kernel/bpf/ringbuf.c:226 [inline] ringbuf_map_free+0xff/0x1e0 kernel/bpf/ringbuf.c:235 bpf_map_free kernel/bpf/syscall.c:838 [inline] bpf_map_free_deferred+0x17c/0x310 kernel/bpf/syscall.c:862 process_one_work kernel/workqueue.c:3229 [inline] process_scheduled_works+0xa2b/0x1b60 kernel/workqueue.c:3310 worker_thread+0xedf/0x1550 kernel/workqueue.c:3391 kthread+0x535/0x6b0 kernel/kthread.c:389 ret_from_fork+0x6e/0x90 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244CPU: 1 UID: 0 PID: 17276 Comm: syz.1.16450 Not tainted 6.12.0-05490-g9bb88c659673 #8Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-3.fc41 04/01/2014

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:dm-integrity: Avoid divide by zero in table status in Inline modeIn Inline mode, the journal is unused, and journal_sectors is zero.Calculating the journal watermark requires dividing by journal_sectors,which should be done only if the journal is configured.Otherwise, a simple table query (dmsetup table) can cause OOPS.This bug did not show on some systems, perhaps only due tocompiler optimization.On my 32-bit testing machine, this reliably crashes with the following: : Oops: divide error: 0000 [#1] PREEMPT SMP : CPU: 0 UID: 0 PID: 2450 Comm: dmsetup Not tainted 6.14.0-rc2+ #959 : EIP: dm_integrity_status+0x2f8/0xab0 [dm_integrity] ...

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

CVE-2025-21879 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix use-after-free on inode when scanning root during em shrinkingAt btrfs_scan_root() we are accessing the inode's root (and fs_info) in acall to btrfs_fs_closing() after we have scheduled the inode for a delayediput, and that can result in a use-after-free on the inode in case thecleaner kthread does the iput before we dereference the inode in the callto btrfs_fs_closing().Fix this by using the fs_info stored already in a local variable insteadof doing inode->root->fs_info.

CVE-2025-21880 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:drm/xe/userptr: fix EFAULT handlingCurrently we treat EFAULT from hmm_range_fault() as a non-fatal errorwhen called from xe_vm_userptr_pin() with the idea that we want to avoidkilling the entire vm and chucking an error, under the assumption thatthe user just did an unmap or something, and has no intention ofactually touching that memory from the GPU. At this point we havealready zapped the PTEs so any access should generate a page fault, andif the pin fails there also it will then become fatal.However it looks like it's possible for the userptr vma to still be onthe rebind list in preempt_rebind_work_func(), if we had to retry thepin again due to something happening in the caller before we did therebind step, but in the meantime needing to re-validate the userptr andthis time hitting the EFAULT.This explains an internal user report of hitting:[ 191.738349] WARNING: CPU: 1 PID: 157 at drivers/gpu/drm/xe/xe_res_cursor.h:158 xe_pt_stage_bind.constprop.0+0x60a/0x6b0 [xe][ 191.738551] Workqueue: xe-ordered-wq preempt_rebind_work_func [xe][ 191.738616] RIP: 0010:xe_pt_stage_bind.constprop.0+0x60a/0x6b0 [xe][ 191.738690] Call Trace:[ 191.738692] [ 191.738694] ? show_regs+0x69/0x80[ 191.738698] ? __warn+0x93/0x1a0[ 191.738703] ? xe_pt_stage_bind.constprop.0+0x60a/0x6b0 [xe][ 191.738759] ? report_bug+0x18f/0x1a0[ 191.738764] ? handle_bug+0x63/0xa0[ 191.738767] ? exc_invalid_op+0x19/0x70[ 191.738770] ? asm_exc_invalid_op+0x1b/0x20[ 191.738777] ? xe_pt_stage_bind.constprop.0+0x60a/0x6b0 [xe][ 191.738834] ? ret_from_fork_asm+0x1a/0x30[ 191.738849] bind_op_prepare+0x105/0x7b0 [xe][ 191.738906] ? dma_resv_reserve_fences+0x301/0x380[ 191.738912] xe_pt_update_ops_prepare+0x28c/0x4b0 [xe][ 191.738966] ? kmemleak_alloc+0x4b/0x80[ 191.738973] ops_execute+0x188/0x9d0 [xe][ 191.739036] xe_vm_rebind+0x4ce/0x5a0 [xe][ 191.739098] ? trace_hardirqs_on+0x4d/0x60[ 191.739112] preempt_rebind_work_func+0x76f/0xd00 [xe]Followed by NPD, when running some workload, since the sg was neveractually populated but the vma is still marked for rebind when it shouldbe skipped for this special EFAULT case.

Then, the operation on the same pfn is performedin uprobe_write_opcode()->__replace_page() to unconditional decrease theRSS count and old_folio's refcount.Therefore, two bugs are introduced: 1. The RSS count is incorrect, when process exit, the check_mm() report error "Bad rss-count". 2. The reserved folio (zero folio) is freed when folio->refcount is zero, then free_pages_prepare->free_page_is_bad() report error "Bad page state".There is more, the following warning could also theoretically be triggered: __replace_page() -> ... -> folio_remove_rmap_pte() -> VM_WARN_ON_FOLIO(is_zero_folio(folio), folio)Considering that uprobe hit on the zero folio is a very rare case, justreject zero old folio immediately after get_user_page_vma_remote().[ mingo: Cleaned up the changelog ]

CVE-2025-21892 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/mlx5: Fix the recovery flow of the UMR QPThis patch addresses an issue in the recovery flow of the UMR QP,ensuring tasks do not get stuck, as highlighted by the call trace [1].During recovery, before transitioning the QP to the RESET state, thesoftware must wait for all outstanding WRs to complete.Failing to do so can cause the firmware to skip sending some flushedCQEs with errors and simply discard them upon the RESET, as per the IBspecification.This race condition can result in lost CQEs and tasks becoming stuck.To resolve this, the patch sends a final WR which serves only as abarrier before moving the QP state to RESET.Once a CQE is received for that final WR, it guarantees that nooutstanding WRs remain, making it safe to transition the QP to RESET andsubsequently back to RTS, restoring proper functionality.Note:For the barrier WR, we simply reuse the failed and ready WR.Since the QP is in an error state, it will only receiveIB_WC_WR_FLUSH_ERR.

CVE-2025-21893 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:keys: Fix UAF in key_put()Once a key's reference count has been reduced to 0, the garbage collectorthread may destroy it at any time and so key_put() is not allowed to touchthe key after that point. The most key_put() is normally allowed to do isto touch key_gc_work as that's a static global variable.However, in an effort to speed up the reclamation of quota, this is nowdone in key_put() once the key's usage is reduced to 0 - but now the codeis looking at the key after the deadline, which is forbidden.Fix this by using a flag to indicate that a key can be gc'd now rather thanlooking at the key's refcount in the garbage collector.

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:net: gso: fix ownership in __udp_gso_segmentIn __udp_gso_segment the skb destructor is removed before segmenting theskb but the socket reference is kept as-is. This is an issue if theoriginal skb is later orphaned as we can hit the following bug: kernel BUG at ./include/linux/skbuff.h:3312! (skb_orphan) RIP: 0010:ip_rcv_core+0x8b2/0xca0 Call Trace: ip_rcv+0xab/0x6e0 __netif_receive_skb_one_core+0x168/0x1b0 process_backlog+0x384/0x1100 __napi_poll.constprop.0+0xa1/0x370 net_rx_action+0x925/0xe50The above can happen following a sequence of events when usingOpenVSwitch, when an OVS_ACTION_ATTR_USERSPACE action precedes anOVS_ACTION_ATTR_OUTPUT action:1. OVS_ACTION_ATTR_USERSPACE is handled (in do_execute_actions): the skb goes through queue_gso_packets and then __udp_gso_segment, where its destructor is removed.2. The segments' data are copied and sent to userspace.3. OVS_ACTION_ATTR_OUTPUT is handled (in do_execute_actions) and the same original skb is sent to its path.4. If it later hits skb_orphan, we hit the bug.Fix this by also removing the reference to the socket in__udp_gso_segment.

Description: In the Linux kernel, the following vulnerability has been resolved:nvme-tcp: fix potential memory corruption in nvme_tcp_recv_pdu()nvme_tcp_recv_pdu() doesn't check the validity of the header length.When header digests are enabled, a target might send a packet with aninvalid header length (e.g. 255), causing nvme_tcp_verify_hdgst()to access memory outside the allocated area and cause memory corruptionsby overwriting it with the calculated digest.Fix this by rejecting packets with an unexpected header length.

CVE-2025-21928 Severity: Moderate CVSS3 score: 5.5

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:x86/microcode/AMD: Fix out-of-bounds on systems with CPU-less NUMA nodesCurrently, load_microcode_amd() iterates over all NUMA nodes, retrieves theirCPU masks and unconditionally accesses per-CPU data for the first CPU of eachmask.According to Documentation/admin-guide/mm/numaperf.rst: "Some memory may share the same node as a CPU, and others are provided as memory only nodes."Therefore, some node CPU masks may be empty and wouldn't have a "first CPU".On a machine with far memory (and therefore CPU-less NUMA nodes):- cpumask_of_node(nid) is 0- cpumask_first(0) is CONFIG_NR_CPUS- cpu_data(CONFIG_NR_CPUS) accesses the cpu_info per-CPU array at an index that is 1 out of boundsThis does not have any security implications since flashing microcode isa privileged operation but I believe this has reliability implications bypotentially corrupting memory while flashing a microcode update.When booting with CONFIG_UBSAN_BOUNDS=y on an AMD machine that flashesa microcode update.

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

CVE-2025-22014 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:soc: qcom: pdr: Fix the potential deadlockWhen some client process A call pdr_add_lookup() to add the look up forthe service and does schedule locator work, later a process B got a newserver packet indicating locator is up and call pdr_locator_new_server()which eventually sets pdr->locator_init_complete to true which process Asees and takes list lock and queries domain list but it will timeout dueto deadlock as the response will queued to the same qmi->wq and it isordered workqueue and process B is not able to complete new serverrequest work due to deadlock on list lock.Fix it by removing the unnecessary list iteration as the list iterationis already being done inside locator work, so avoid it here and justcall schedule_work() here. Process A Process B process_scheduled_works()pdr_add_lookup() qmi_data_ready_work() process_scheduled_works() pdr_locator_new_server() pdr->locator_init_complete=true; pdr_locator_work() mutex_lock(&pdr->list_lock); pdr_locate_service() mutex_lock(&pdr->list_lock); pdr_get_domain_list() pr_err("PDR: %s get domain list txn wait failed: %d\n", req->service_name, ret);Timeout error log due to deadlock:" PDR: tms/servreg get domain list txn wait failed: -110 PDR: service lookup for msm/adsp/sensor_pd:tms/servreg failed: -110"Thanks to Bjorn and Johan for letting me know that this commit also fixesan audio regression when using the in-kernel pd-mapper as that makes iteasier to hit this race.

CVE-2025-22044 Severity: Moderate CVSS3 score: 5.5

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

CVE-2025-22060 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: mvpp2: Prevent parser TCAM memory corruptionProtect the parser TCAM/SRAM memory, and the cached (shadow) SRAMinformation, from concurrent modifications.Both the TCAM and SRAM tables are indirectly accessed by configuringan index register that selects the row to read or write to. This meansthat operations must be atomic in order to, e.g., avoid spreadingwrites across multiple rows. Since the shadow SRAM array is used tofind free rows in the hardware table, it must also be protected inorder to avoid TOCTOU errors where multiple cores allocate the samerow.This issue was detected in a situation where `mvpp2_set_rx_mode()` ranconcurrently on two CPUs. In this particular case theMVPP2_PE_MAC_UC_PROMISCUOUS entry was corrupted, causing theclassifier unit to drop all incoming unicast - indicated by the`rx_classifier_drops` counter.

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

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

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

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

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

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

Userspace software that relies on the autobind featuremight get broken. However, this feature does not seem widely used withthis specific driver as it was not reliable at any point of time, and itis already broken anyway.

In case it is apositive value, new_lockspace would undo all the work, and lockspacewould not be set. __dlm_new_lockspace, however, would treat thatpositive value as a success due to commit 8511a2728ab8 ("dlm: fix usecount with multiple joins").Down the line, device_create_lockspace would pass that NULL lockspace todlm_find_lockspace_local, leading to a NULL pointer dereference.Treating such positive values as successes prevents the problem.

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:bus: mhi: host: Fix race between unprepare and queue_bufA client driver may use mhi_unprepare_from_transfer() to quiesceincoming data during the client driver's tear down. The client drivermight also be processing data at the same time, resulting in a call tomhi_queue_buf() which will invoke mhi_gen_tre(). If mhi_gen_tre() runsafter mhi_unprepare_from_transfer() has torn down the channel, a panicwill occur due to an invalid dereference leading to a page fault.This occurs because mhi_gen_tre() does not verify the channel stateafter locking it. Fix this by having mhi_gen_tre() confirm the channelstate is valid, or return error to avoid accessing deinitialized data.[mani: added stable tag]

This value is stored inirq_desc->affinity_hint, but once stmmac_request_irq_multi_msi()returns, the pointer becomes dangling.The affinity_hint is exposed via procfs with S_IRUGO permissions,allowing any unprivileged process to read it. Accessing this stalepointer can lead to:- a kernel oops or panic if the referenced memory has been released and unmapped, or- leakage of kernel data into userspace if the memory is re-used for other purposes.All platforms that use stmmac with PCI MSI (Intel, Loongson, etc) areaffected.

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

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

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

So as soon as vsc_tp_xfer() tries to add the crc tobuf[] the fortify-panic handler gets triggered:[ 80.842193] memcpy: detected buffer overflow: 4 byte write of buffer size 0[ 80.842243] WARNING: CPU: 4 PID: 272 at lib/string_helpers.c:1032 __fortify_report+0x45/0x50...[ 80.843175] __fortify_panic+0x9/0xb[ 80.843186] vsc_tp_xfer.cold+0x67/0x67 [mei_vsc_hw][ 80.843210] ? seqcount_lockdep_reader_access.constprop.0+0x82/0x90[ 80.843229] ? lockdep_hardirqs_on+0x7c/0x110[ 80.843250] mei_vsc_hw_start+0x98/0x120 [mei_vsc][ 80.843270] mei_reset+0x11d/0x420 [mei]The easiest fix would be to just drop the counted-by but with the exceptionof the ack buffer in vsc_tp_xfer_helper() which only contains enough roomfor the packet-header, all other uses of vsc_tp_packet always use a bufferof VSC_TP_MAX_XFER_SIZE bytes for the packet.Instead of just dropping the counted-by, split the vsc_tp_packet structdefinition into a header and a full-packet definition and use a fixedsize buf[] in the packet definition, this way fortify-source bufferoverrun checking still works when enabled.

Description: In the Linux kernel, the following vulnerability has been resolved:xen-netfront: handle NULL returned by xdp_convert_buff_to_frame()The function xdp_convert_buff_to_frame() may return NULL if it failsto correctly convert the XDP buffer into an XDP frame due to memoryconstraints, internal errors, or invalid data. Failing to check for NULLmay lead to a NULL pointer dereference if the result is used later inprocessing, potentially causing crashes, data corruption, or undefinedbehavior.On XDP redirect failure, the associated page must be released explicitlyif it was previously retained via get_page(). Failing to do so may resultin a memory leak, as the pages reference count is not decremented.

CVE-2025-37821 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:sched/eevdf: Fix se->slice being set to U64_MAX and resulting crashThere is a code path in dequeue_entities() that can set the slice of asched_entity to U64_MAX, which sometimes results in a crash.The offending case is when dequeue_entities() is called to dequeue adelayed group entity, and then the entity's parent's dequeue is delayed.In that case:1. In the if (entity_is_task(se)) else block at the beginning of dequeue_entities(), slice is set to cfs_rq_min_slice(group_cfs_rq(se)). If the entity was delayed, then it has no queued tasks, so cfs_rq_min_slice() returns U64_MAX.2. The first for_each_sched_entity() loop dequeues the entity.3. If the entity was its parent's only child, then the next iteration tries to dequeue the parent.4. If the parent's dequeue needs to be delayed, then it breaks from the first for_each_sched_entity() loop _without updating slice_.5. The second for_each_sched_entity() loop sets the parent's ->slice to the saved slice, which is still U64_MAX.This throws off subsequent calculations with potentially catastrophicresults. A manifestation we saw in production was:6. In update_entity_lag(), se->slice is used to calculate limit, which ends up as a huge negative number.7. limit is used in se->vlag = clamp(vlag, -limit, limit). Because limit is negative, vlag > limit, so se->vlag is set to the same huge negative number.8. In place_entity(), se->vlag is scaled, which overflows and results in another huge (positive or negative) number.9. The adjusted lag is subtracted from se->vruntime, which increases or decreases se->vruntime by a huge number.10. pick_eevdf() calls entity_eligible()/vruntime_eligible(), which incorrectly returns false because the vruntime is so far from the other vruntimes on the queue, causing the (vruntime - cfs_rq->min_vruntime) * load calulation to overflow.11. Nothing appears to be eligible, so pick_eevdf() returns NULL.12. pick_next_entity() tries to dereference the return value of pick_eevdf() and crashes.Dumping the cfs_rq states from the core dumps with drgn showed tell-talehuge vruntime ranges and bogus vlag values, and I also traced se->slicebeing set to U64_MAX on live systems (which was usually "benign" sincethe rest of the runqueue needed to be in a particular state to crash).Fix it in dequeue_entities() by always setting slice from the firstnon-empty cfs_rq.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: ufs: mcq: Add NULL check in ufshcd_mcq_abort()A race can occur between the MCQ completion path and the abort handler:once a request completes, __blk_mq_free_request() sets rq->mq_hctx toNULL, meaning the subsequent ufshcd_mcq_req_to_hwq() call inufshcd_mcq_abort() can return a NULL pointer. If this NULL pointer isdereferenced, the kernel will crash.Add a NULL check for the returned hwq pointer. If hwq is NULL, log anerror and return FAILED, preventing a potential NULL-pointerdereference. As suggested by Bart, the ufshcd_cmd_inflight() check isremoved.This is similar to the fix in commit 74736103fb41 ("scsi: ufs: core: Fixufshcd_abort_one racing issue").This is found by our static analysis tool KNighter.

CVE-2025-37843 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: pciehp: Avoid unnecessary device replacement checkHot-removal of nested PCI hotplug ports suffers from a long-standing racecondition which can lead to a deadlock: A parent hotplug port acquirespci_lock_rescan_remove(), then waits for pciehp to unbind from a childhotplug port. Meanwhile that child hotplug port tries to acquirepci_lock_rescan_remove() as well in order to remove its own children.The deadlock only occurs if the parent acquires pci_lock_rescan_remove()first, not if the child happens to acquire it first.Several workarounds to avoid the issue have been proposed and discardedover the years, e.g.:https://lore.kernel.org/r/4c882e25194ba8282b78fe963fec8faae7cf23eb.1529173804.git.lukas@wunner.de/A proper fix is being worked on, but needs more time as it is nontrivialand necessarily intrusive.Recent commit 9d573d19547b ("PCI: pciehp: Detect device replacement duringsystem sleep") provokes more frequent occurrence of the deadlock whenremoving more than one Thunderbolt device during system sleep. The commitsought to detect device replacement, but also triggered on device removal.Differentiating reliably between replacement and removal is impossiblebecause pci_get_dsn() returns 0 both if the device was removed, as well asif it was replaced with one lacking a Device Serial Number.Avoid the more frequent occurrence of the deadlock by checking whether thehotplug port itself was hot-removed. If so, there's no sense in checkingwhether its child device was replaced.This works because the ->resume_noirq() callback is invoked in top-downorder for the entire hierarchy: A parent hotplug port detecting devicereplacement (or removal) marks all children as removed usingpci_dev_set_disconnected() and a child hotplug port can then reliablydetect being removed.

CVE-2025-37864 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: dsa: clean up FDB, MDB, VLAN entries on unbindAs explained in many places such as commit b117e1e8a86d ("net: dsa:delete dsa_legacy_fdb_add and dsa_legacy_fdb_del"), DSA is written giventhe assumption that higher layers have balanced additions/deletions.As such, it only makes sense to be extremely vocal when thoseassumptions are violated and the driver unbinds with entries stillpresent.But Ido Schimmel points out a very simple situation where that is wrong:https://lore.kernel.org/netdev/ZDazSM5UsPPjQuKr@shredder/(also briefly discussed by me in the aforementioned commit).Basically, while the bridge bypass operations are not something that DSAexplicitly documents, and for the majority of DSA drivers this APIsimply causes them to go to promiscuous mode, that isn't the case forall drivers. Some have the necessary requirements for bridge bypassoperations to do something useful - see dsa_switch_supports_uc_filtering().Although in tools/testing/selftests/net/forwarding/local_termination.sh,we made an effort to popularize better mechanisms to manage addressfilters on DSA interfaces from user space - namely macvlan for unicast,and setsockopt(IP_ADD_MEMBERSHIP) - through mtools - for multicast, thefact is that 'bridge fdb add ... self static local' also exists askernel UAPI, and might be useful to someone, even if only for a quickhack.It seems counter-productive to block that path by implementing shim.ndo_fdb_add and .ndo_fdb_del operations which just return -EOPNOTSUPPin order to prevent the ndo_dflt_fdb_add() and ndo_dflt_fdb_del() fromrunning, although we could do that.Accepting that cleanup is necessary seems to be the only option.Especially since we appear to be coming back at this from a differentangle as well. Russell King is noticing that the WARN_ON() triggers evenfor VLANs:https://lore.kernel.org/netdev/Z_li8Bj8bD4-BYKQ@shell.armlinux.org.uk/What happens in the bug report above is that dsa_port_do_vlan_del() fails,then the VLAN entry lingers on, and then we warn on unbind and leak it.This is not a straight revert of the blamed commit, but we now add aninformational print to the kernel log (to still have a way to seethat bugs exist), and some extra comments gathered from past years'experience, to justify the logic.

Description: In the Linux kernel, the following vulnerability has been resolved:net: dsa: mv88e6xxx: fix -ENOENT when deleting VLANs and MST is unsupportedRussell King reports that on the ZII dev rev B, deleting a bridge VLANfrom a user port fails with -ENOENT:https://lore.kernel.org/netdev/Z_lQXNP0s5-IiJzd@shell.armlinux.org.uk/This comes from mv88e6xxx_port_vlan_leave() -> mv88e6xxx_mst_put(),which tries to find an MST entry in &chip->msts associated with the SID,but fails and returns -ENOENT as such.But we know that this chip does not support MST at all, so that is notsurprising. The question is why does the guard in mv88e6xxx_mst_put()not exit early: if (!sid) return 0;And the answer seems to be simple: the sid comes from vlan.sid whichsupposedly was previously populated by mv88e6xxx_vtu_get().But some chip->info->ops->vtu_getnext() implementations do not populatevlan.sid, for example see mv88e6185_g1_vtu_getnext(). In that case,later in mv88e6xxx_port_vlan_leave() we are using a garbage sid which isjust residual stack memory.Testing for sid == 0 covers all cases of a non-bridge VLAN or a bridgeVLAN mapped to the default MSTI. For some chips, SID 0 is valid andinstalled by mv88e6xxx_stu_setup(). A chip which does not support theSTU would implicitly only support mapping all VLANs to the default MSTI,so although SID 0 is not valid, it would be sufficient, if we were tozero-initialize the vlan structure, to fix the bug, due to thecoincidence that a test for vlan.sid == 0 already exists and leads tothe same (correct) behavior.Another option which would be sufficient would be to add a test formv88e6xxx_has_stu() inside mv88e6xxx_mst_put(), symmetric to the onewhich already exists in mv88e6xxx_mst_get(). But that placement meansthe caller will have to dereference vlan.sid, which means it will accessuninitialized memory, which is not nice even if it ignores it later.So we end up making both modifications, in order to not rely just on thesid == 0 coincidence, but also to avoid having uninitialized structurefields which might get temporarily accessed.

CVE-2025-37875 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:igc: fix PTM cycle trigger logicWriting to clear the PTM status 'valid' bit while the PTM cycle istriggered results in unreliable PTM operation. To fix this, clear thePTM 'trigger' and status after each PTM transaction.The issue can be reproduced with the following:$ sudo phc2sys -R 1000 -O 0 -i tsn0 -mNote: 1000 Hz (-R 1000) is unrealistically large, but provides a way toquickly reproduce the issue.PHC2SYS exits with:"ioctl PTP_OFFSET_PRECISE: Connection timed out" when the PTM transaction failsThis patch also fixes a hang in igc_probe() when loading the igcdriver in the kdump kernel on systems supporting PTM.The igc driver running in the base kernel enables PTM trigger inigc_probe(). Therefore the driver is always in PTM trigger mode,except in brief periods when manually triggering a PTM cycle.When a crash occurs, the NIC is reset while PTM trigger is enabled.Due to a hardware problem, the NIC is subsequently in a bad busmasterstate and doesn't handle register reads/writes. When runningigc_probe() in the kdump kernel, the first register access to a NICregister hangs driver probing and ultimately breaks kdump.With this patch, igc has PTM trigger disabled most of the time,and the trigger is only enabled for very brief (10 - 100 us) periodswhen manually triggering a PTM cycle. Chances that a crash occursduring a PTM trigger are not 0, but extremely reduced.

CVE-2025-37931 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: adjust subpage bit start based on sectorsizeWhen running machines with 64k page size and a 16k nodesize we startedseeing tree log corruption in production. This turned out to be becausewe were not writing out dirty blocks sometimes, so this in fact affectsall metadata writes.When writing out a subpage EB we scan the subpage bitmap for a dirtyrange. If the range isn't dirty we do bit_start++;to move onto the next bit. The problem is the bitmap is based on thenumber of sectors that an EB has. So in this case, we have a 64kpagesize, 16k nodesize, but a 4k sectorsize. This means our bitmap is 4bits for every node. With a 64k page size we end up with 4 nodes perpage.To make this easier this is how everything looks[0 16k 32k 48k ] logical address[0 4 8 12 ] radix tree offset[ 64k page ] folio[ 16k eb ][ 16k eb ][ 16k eb ][ 16k eb ] extent buffers[ | | | | | | | | | | | | | | | | ] bitmapNow we use all of our addressing based on fs_info->sectorsize_bits, soas you can see the above our 16k eb->start turns into radix entry 4.When we find a dirty range for our eb, we correctly do bit_start +=sectors_per_node, because if we start at bit 0, the next bit for thenext eb is 4, to correspond to eb->start 16k.However if our range is clean, we will do bit_start++, which will nowput us offset from our radix tree entries.In our case, assume that the first time we check the bitmap the block isnot dirty, we increment bit_start so now it == 1, and then we looparound and check again. This time it is dirty, and we go to find thatstart using the following equation start = folio_start + bit_start * fs_info->sectorsize;so in the case above, eb->start 0 is now dirty, and we calculate startas 0 + 1 * fs_info->sectorsize = 4096 4096 >> 12 = 1Now we're looking up the radix tree for 1, and we won't find an eb.What's worse is now we're using bit_start == 1, so we do bit_start +=sectors_per_node, which is now 5. If that eb is dirty we will run intothe same thing, we will look at an offset that is not populated in theradix tree, and now we're skipping the writeout of dirty extent buffers.The best fix for this is to not use sectorsize_bits to address nodes,but that's a larger change. Since this is a fs corruption problem fixit simply by always using sectors_per_node to increment the start bit.

CVE-2025-37936 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:perf/x86/intel: KVM: Mask PEBS_ENABLE loaded for guest with vCPU's value.When generating the MSR_IA32_PEBS_ENABLE value that will be loaded onVM-Entry to a KVM guest, mask the value with the vCPU's desired PEBS_ENABLEvalue. Consulting only the host kernel's host vs. guest masks results inrunning the guest with PEBS enabled even when the guest doesn't want to usePEBS. Because KVM uses perf events to proxy the guest virtual PMU, simplylooking at exclude_host can't differentiate between events created by hostuserspace, and events created by KVM on behalf of the guest.Running the guest with PEBS unexpectedly enabled typically manifests ascrashes due to a near-infinite stream of #PFs. E.g. if the guest hasn'twritten MSR_IA32_DS_AREA, the CPU will hit page faults on address '0' whentrying to record PEBS events.The issue is most easily reproduced by running `perf kvm top` from beforecommit 7b100989b4f6 ("perf evlist: Remove __evlist__add_default") (afterwhich, `perf kvm top` effectively stopped using PEBS). The userspace sideof perf creates a guest-only PEBS event, which intel_guest_get_msrs()misconstrues a guest-*owned* PEBS event.Arguably, this is a userspace bug, as enabling PEBS on guest-only eventssimply cannot work, and userspace can kill VMs in many other ways (thereis no danger to the host). However, even if this is considered to be baduserspace behavior, there's zero downside to perf/KVM restricting PEBS toguest-owned events.Note, commit 854250329c02 ("KVM: x86/pmu: Disable guest PEBS temporarilyin two rare situations") fixed the case where host userspace is profilingKVM *and* userspace, but missed the case where userspace is profiling onlyKVM.

CVE-2025-37940 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ftrace: Add cond_resched() to ftrace_graph_set_hash()When the kernel contains a large number of functions that can be traced,the loop in ftrace_graph_set_hash() may take a lot of time to execute.This may trigger the softlockup watchdog.Add cond_resched() within the loop to allow the kernel to remainresponsive even when processing a large number of functions.This matches the cond_resched() that is used in other locations of thecode that iterates over all functions that can be traced.

CVE-2025-37944 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: ath12k: Fix invalid entry fetch in ath12k_dp_mon_srng_processCurrently, ath12k_dp_mon_srng_process uses ath12k_hal_srng_src_get_next_entryto fetch the next entry from the destination ring. This is incorrect becauseath12k_hal_srng_src_get_next_entry is intended for source rings, not destinationrings. This leads to invalid entry fetches, causing potential data corruption orcrashes due to accessing incorrect memory locations. This happens because thesource ring and destination ring have different handling mechanisms and usingthe wrong function results in incorrect pointer arithmetic and ring management.To fix this issue, replace the call to ath12k_hal_srng_src_get_next_entry withath12k_hal_srng_dst_get_next_entry in ath12k_dp_mon_srng_process. This ensuresthat the correct function is used for fetching entries from the destinationring, preventing invalid memory accesses.Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1Tested-on: WCN7850 hw2.0 WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

CVE-2025-37945 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: phy: allow MDIO bus PM ops to start/stop state machine for phylink-controlled PHYDSA has 2 kinds of drivers:1. Those who call dsa_switch_suspend() and dsa_switch_resume() from their device PM ops: qca8k-8xxx, bcm_sf2, microchip ksz2. Those who don't: all others. The above methods should be optional.For type 1, dsa_switch_suspend() calls dsa_user_suspend() -> phylink_stop(),and dsa_switch_resume() calls dsa_user_resume() -> phylink_start().These seem good candidates for setting mac_managed_pm = true becausethat is essentially its definition [1], but that does not seem to be thebiggest problem for now, and is not what this change focuses on.Talking strictly about the 2nd category of DSA drivers here (whichdo not have MAC managed PM, meaning that for their attached PHYs,mdio_bus_phy_suspend() and mdio_bus_phy_resume() should run in full),I have noticed that the following warning from mdio_bus_phy_resume() istriggered: WARN_ON(phydev->state != PHY_HALTED && phydev->state != PHY_READY && phydev->state != PHY_UP);because the PHY state machine is running.It's running as a result of a previous dsa_user_open() -> ... ->phylink_start() -> phy_start() having been initiated by the user.The previous mdio_bus_phy_suspend() was supposed to have calledphy_stop_machine(), but it didn't. So this is why the PHY is in statePHY_NOLINK by the time mdio_bus_phy_resume() runs.mdio_bus_phy_suspend() did not call phy_stop_machine() because forphylink, the phydev->adjust_link function pointer is NULL. This seems atechnicality introduced by commit fddd91016d16 ("phylib: fix PAL statemachine restart on resume"). That commit was written before phylinkexisted, and was intended to avoid crashing with consumer drivers whichdon't use the PHY state machine - phylink always does, when using a PHY.But phylink itself has historically not been developed withsuspend/resume in mind, and apparently not tested too much in thatscenario, allowing this bug to exist unnoticed for so long. Plus, priorto the WARN_ON(), it would have likely been invisible.This issue is not in fact restricted to type 2 DSA drivers (according tothe above ad-hoc classification), but can be extrapolated to any MACdriver with phylink and MDIO-bus-managed PHY PM ops. DSA is just wherethe issue was reported. Assuming mac_managed_pm is set correctly, aquick search indicates the following other drivers might be affected:$ grep -Zlr PHYLINK_NETDEV drivers/ | xargs -0 grep -L mac_managed_pmdrivers/net/ethernet/atheros/ag71xx.cdrivers/net/ethernet/microchip/sparx5/sparx5_main.cdrivers/net/ethernet/microchip/lan966x/lan966x_main.cdrivers/net/ethernet/freescale/dpaa2/dpaa2-mac.cdrivers/net/ethernet/freescale/fs_enet/fs_enet-main.cdrivers/net/ethernet/freescale/dpaa/dpaa_eth.cdrivers/net/ethernet/freescale/ucc_geth.cdrivers/net/ethernet/freescale/enetc/enetc_pf_common.cdrivers/net/ethernet/marvell/mvpp2/mvpp2_main.cdrivers/net/ethernet/marvell/mvneta.cdrivers/net/ethernet/marvell/prestera/prestera_main.cdrivers/net/ethernet/mediatek/mtk_eth_soc.cdrivers/net/ethernet/altera/altera_tse_main.cdrivers/net/ethernet/wangxun/txgbe/txgbe_phy.cdrivers/net/ethernet/meta/fbnic/fbnic_phylink.cdrivers/net/ethernet/tehuti/tn40_phy.cdrivers/net/ethernet/mscc/ocelot_net.cMake the existing conditions dependent on the PHY device having aphydev->phy_link_change() implementation equal to the defaultphy_link_change() provided by phylib. Otherwise, we implicitly know thatthe phydev has the phylink-provided phylink_phy_change() callback, andwhen phylink is used, the PHY state machine always needs to be stopped/started on the suspend/resume path. The code is structured as such thatif phydev->phy_link_change() is absent, it is a matter of time until thekernel will crash - no need to further complicate the test.Thus, for the situation where the PM is not managed b---truncated---

CVE-2025-37957 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: SVM: Forcibly leave SMM mode on SHUTDOWN interceptionPreviously, commit ed129ec9057f ("KVM: x86: forcibly leave nested modeon vCPU reset") addressed an issue where a triple fault occurring innested mode could lead to use-after-free scenarios. However, the commitdid not handle the analogous situation for System Management Mode (SMM).This omission results in triggering a WARN when KVM forces a vCPU INITafter SHUTDOWN interception while the vCPU is in SMM. This situation wasreprodused using Syzkaller by: 1) Creating a KVM VM and vCPU 2) Sending a KVM_SMI ioctl to explicitly enter SMM 3) Executing invalid instructions causing consecutive exceptions and eventually a triple faultThe issue manifests as follows: WARNING: CPU: 0 PID: 25506 at arch/x86/kvm/x86.c:12112 kvm_vcpu_reset+0x1d2/0x1530 arch/x86/kvm/x86.c:12112 Modules linked in: CPU: 0 PID: 25506 Comm: syz-executor.0 Not tainted 6.1.130-syzkaller-00157-g164fe5dde9b6 #0 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014 RIP: 0010:kvm_vcpu_reset+0x1d2/0x1530 arch/x86/kvm/x86.c:12112 Call Trace: shutdown_interception+0x66/0xb0 arch/x86/kvm/svm/svm.c:2136 svm_invoke_exit_handler+0x110/0x530 arch/x86/kvm/svm/svm.c:3395 svm_handle_exit+0x424/0x920 arch/x86/kvm/svm/svm.c:3457 vcpu_enter_guest arch/x86/kvm/x86.c:10959 [inline] vcpu_run+0x2c43/0x5a90 arch/x86/kvm/x86.c:11062 kvm_arch_vcpu_ioctl_run+0x50f/0x1cf0 arch/x86/kvm/x86.c:11283 kvm_vcpu_ioctl+0x570/0xf00 arch/x86/kvm/../../../virt/kvm/kvm_main.c:4122 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:870 [inline] __se_sys_ioctl fs/ioctl.c:856 [inline] __x64_sys_ioctl+0x19a/0x210 fs/ioctl.c:856 do_syscall_x64 arch/x86/entry/common.c:51 [inline] do_syscall_64+0x35/0x80 arch/x86/entry/common.c:81 entry_SYSCALL_64_after_hwframe+0x6e/0xd8Architecturally, INIT is blocked when the CPU is in SMM, hence KVM's WARN()in kvm_vcpu_reset() to guard against KVM bugs, e.g. to detect improperemulation of INIT. SHUTDOWN on SVM is a weird edge case where KVM needs todo _something_ sane with the VMCB, since it's technically undefined, andINIT is the least awful choice given KVM's ABI.So, double down on stuffing INIT on SHUTDOWN, and force the vCPU out ofSMM to avoid any weirdness (and the WARN).Found by Linux Verification Center (linuxtesting.org) with Syzkaller.[sean: massage changelog, make it clear this isn't architectural behavior]

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Scrub packet on bpf_redirect_peerWhen bpf_redirect_peer is used to redirect packets to a device inanother network namespace, the skb isn't scrubbed. That can lead skbinformation from one namespace to be "misused" in another namespace.As one example, this is causing Cilium to drop traffic when usingbpf_redirect_peer to redirect packets that just went through IPsecdecryption to a container namespace. The following pwru trace shows (1)the packet path from the host's XFRM layer to the container's XFRMlayer where it's dropped and (2) the number of active skb extensions ateach function.

When we decrypt the IPsec packet,the XFRM state used for decryption is set in the skb extensions. Thisinformation is preserved across the netns switch. When we reach theXFRM policy check in the container's netns, __xfrm_policy_check dropsthe packet with LINUX_MIB_XFRMINNOPOLS because a (container-side) XFRMpolicy can't be found that matches the (host-side) XFRM state used fordecryption.This patch fixes this by scrubbing the packet when usingbpf_redirect_peer, as is done on typical netns switches via vethdevices except skb->mark and skb->tstamp are not zeroed.

CVE-2025-37968 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:iio: light: opt3001: fix deadlock due to concurrent flag accessThe threaded IRQ function in this driver is reading the flag twice: once tolock a mutex and once to unlock it. Even though the code setting the flagis designed to prevent it, there are subtle cases where the flag could betrue at the mutex_lock stage and false at the mutex_unlock stage. Thisresults in the mutex not being unlocked, resulting in a deadlock.Fix it by making the opt3001_irq() code generally more robust, reading theflag into a variable and using the variable value at both stages.

CVE-2025-37987 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:pds_core: Prevent possible adminq overflow/stuck conditionThe pds_core's adminq is protected by the adminq_lock, which preventsmore than 1 command to be posted onto it at any one time. This makes itso the client drivers cannot simultaneously post adminq commands.However, the completions happen in a different context, which meansmultiple adminq commands can be posted sequentially and all waitingon completion.On the FW side, the backing adminq request queue is only 16 entrieslong and the retry mechanism and/or overflow/stuck prevention islacking. This can cause the adminq to get stuck, so commands are nolonger processed and completions are no longer sent by the FW.As an initial fix, prevent more than 16 outstanding adminq commands sothere's no way to cause the adminq from getting stuck. This worksbecause the backing adminq request queue will never have more than 16pending adminq commands, so it will never overflow. This is done byreducing the adminq depth to 16.

CVE-2025-37988 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fix a couple of races in MNT_TREE_BENEATH handling by do_move_mount()Normally do_lock_mount(path, _) is locking a mountpoint pinned by*path and at the time when matching unlock_mount() unlocks thatlocation it is still pinned by the same thing.Unfortunately, for 'beneath' case it's no longer that simple -the object being locked is not the one *path points to. It's themountpoint of path->mnt. The thing is, without sufficient locking->mnt_parent may change under us and none of the locks are heldat that point. The rules are * mount_lock stabilizes m->mnt_parent for any mount m. * namespace_sem stabilizes m->mnt_parent, provided thatm is mounted. * if either of the above holds and refcount of m is positive,we are guaranteed the same for refcount of m->mnt_parent.namespace_sem nests inside inode_lock(), so do_lock_mount() hasto take inode_lock() before grabbing namespace_sem. It doesrecheck that path->mnt is still mounted in the same place aftergetting namespace_sem, and it does take care to pin the dentry.It is needed, since otherwise we might end up with racing mount --move(or umount) happening while we were getting locks; in that casedentry would no longer be a mountpoint and could've been evictedon memory pressure along with its inode - not something you wantwhen grabbing lock on that inode.However, pinning a dentry is not enough - the matching mount isalso pinned only by the fact that path->mnt is mounted on top itand at that point we are not holding any locks whatsoever, sothe same kind of races could end up with all references tothat mount gone just as we are about to enter inode_lock().If that happens, we are left with filesystem being shut down whilewe are holding a dentry reference on it; results are not pretty.What we need to do is grab both dentry and mount at the same time;that makes inode_lock() safe *and* avoids the problem with fs gettingshut down under us. After taking namespace_sem we verify thatpath->mnt is still mounted (which stabilizes its ->mnt_parent) andcheck that it's still mounted at the same place. From that pointon to the matching namespace_unlock() we are guaranteed thatmount/dentry pair we'd grabbed are also pinned by being the mountpointof path->mnt, so we can quietly drop both the dentry reference (asthe current code does) and mnt one - it's OK to do under namespace_sem,since we are not dropping the final refs.That solves the problem on do_lock_mount() side; unlock_mount()also has one, since dentry is guaranteed to stay pinned only untilthe namespace_unlock(). That's easy to fix - just have inode_unlock()done earlier, while it's still pinned by mp->m_dentry.

CVE-2025-37989 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: phy: leds: fix memory leakA network restart test on a router led to an out-of-memory condition,which was traced to a memory leak in the PHY LED trigger code.The root cause is misuse of the devm API. The registration function(phy_led_triggers_register) is called from phy_attach_direct, notphy_probe, and the unregister function (phy_led_triggers_unregister)is called from phy_detach, not phy_remove. This means the register andunregister functions can be called multiple times for the same PHYdevice, but devm-allocated memory is not freed until the driver isunbound.This also prevents kmemleak from detecting the leak, as the devm APIinternally stores the allocated pointer.Fix this by replacing devm_kzalloc/devm_kcalloc with standardkzalloc/kcalloc, and add the corresponding kfree calls in the unregisterpath.

Description: In the Linux kernel, the following vulnerability has been resolved:net_sched: Flush gso_skb list too during ->change()Previously, when reducing a qdisc's limit via the ->change() operation, onlythe main skb queue was trimmed, potentially leaving packets in the gso_skblist. This could result in NULL pointer dereference when we only checksch->limit against sch->q.qlen.This patch introduces a new helper, qdisc_dequeue_internal(), which ensuresboth the gso_skb list and the main queue are properly flushed when trimmingexcess packets. All relevant qdiscs (codel, fq, fq_codel, fq_pie, hhf, pie)are updated to use this helper in their ->change() routines.

CVE-2025-37995 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:module: ensure that kobject_put() is safe for module type kobjectsIn 'lookup_or_create_module_kobject()', an internal kobject is createdusing 'module_ktype'. So call to 'kobject_put()' on error handlingpath causes an attempt to use an uninitialized completion pointer in'module_kobject_release()'. In this scenario, we just want to releasekobject without an extra synchronization required for a regular moduleunloading process, so adding an extra check whether 'complete()' isactually required makes 'kobject_put()' safe.

Description: In the Linux kernel, the following vulnerability has been resolved:perf/x86/intel: Fix segfault with PEBS-via-PT with sample_freqCurrently, using PEBS-via-PT with a sample frequency instead of a sampleperiod, causes a segfault. For example: BUG: kernel NULL pointer dereference, address: 0000000000000195 ? __die_body.cold+0x19/0x27 ? page_fault_oops+0xca/0x290 ? exc_page_fault+0x7e/0x1b0 ? asm_exc_page_fault+0x26/0x30 ? intel_pmu_pebs_event_update_no_drain+0x40/0x60 ? intel_pmu_pebs_event_update_no_drain+0x32/0x60 intel_pmu_drain_pebs_icl+0x333/0x350 handle_pmi_common+0x272/0x3c0 intel_pmu_handle_irq+0x10a/0x2e0 perf_event_nmi_handler+0x2a/0x50That happens because intel_pmu_pebs_event_update_no_drain() assumes all thepebs_enabled bits represent counter indexes, which is not always the case.In this particular case, bits 60 and 61 are set for PEBS-via-PT purposes.The behaviour of PEBS-via-PT with sample frequency is questionable becausealthough a PMI is generated (PEBS_PMI_AFTER_EACH_RECORD), the period is notadjusted anyway.Putting that aside, fix intel_pmu_pebs_event_update_no_drain() by passingthe mask of counter bits instead of 'size'. Note, prior to the Fixescommit, 'size' would be limited to the maximum counter index, so the issuewas not hit.

CVE-2025-38104 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amdgpu: Replace Mutex with Spinlock for RLCG register access to avoid Priority Inversion in SRIOVRLCG Register Access is a way for virtual functions to safely access GPUregisters in a virtualized environment., including TLB flushes andregister reads. When multiple threads or VFs try to access the sameregisters simultaneously, it can lead to race conditions. By using theRLCG interface, the driver can serialize access to the registers. Thismeans that only one thread can access the registers at a time,preventing conflicts and ensuring that operations are performedcorrectly. Additionally, when a low-priority task holds a mutex that ahigh-priority task needs, ie., If a thread holding a spinlock tries toacquire a mutex, it can lead to priority inversion. register access inamdgpu_virt_rlcg_reg_rw especially in a fast code path is critical.The call stack shows that the function amdgpu_virt_rlcg_reg_rw is beingcalled, which attempts to acquire the mutex. This function is invokedfrom amdgpu_sriov_wreg, which in turn is called fromgmc_v11_0_flush_gpu_tlb.The [ BUG: Invalid wait context ] indicates that a thread is trying toacquire a mutex while it is in a context that does not allow it to sleep(like holding a spinlock).Fixes the below:[ 253.013423] =============================[ 253.013434] [ BUG: Invalid wait context ][ 253.013446] 6.12.0-amdstaging-drm-next-lol-050225 #14 Tainted: G U OE[ 253.013464] -----------------------------[ 253.013475] kworker/0:1/10 is trying to lock:[ 253.013487] ffff9f30542e3cf8 (&adev->virt.rlcg_reg_lock){+.+.}-{3:3}, at: amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu][ 253.013815] other info that might help us debug this:[ 253.013827] context-{4:4}[ 253.013835] 3 locks held by kworker/0:1/10:[ 253.013847] #0: ffff9f3040050f58 ((wq_completion)events){+.+.}-{0:0}, at: process_one_work+0x3f5/0x680[ 253.013877] #1: ffffb789c008be40 ((work_completion)(&wfc.work)){+.+.}-{0:0}, at: process_one_work+0x1d6/0x680[ 253.013905] #2: ffff9f3054281838 (&adev->gmc.invalidate_lock){+.+.}-{2:2}, at: gmc_v11_0_flush_gpu_tlb+0x198/0x4f0 [amdgpu][ 253.014154] stack backtrace:[ 253.014164] CPU: 0 UID: 0 PID: 10 Comm: kworker/0:1 Tainted: G U OE 6.12.0-amdstaging-drm-next-lol-050225 #14[ 253.014189] Tainted: [U]=USER, [O]=OOT_MODULE, [E]=UNSIGNED_MODULE[ 253.014203] Hardware name: Microsoft Corporation Virtual Machine/Virtual Machine, BIOS Hyper-V UEFI Release v4.1 11/18/2024[ 253.014224] Workqueue: events work_for_cpu_fn[ 253.014241] Call Trace:[ 253.014250] [ 253.014260] dump_stack_lvl+0x9b/0xf0[ 253.014275] dump_stack+0x10/0x20[ 253.014287] __lock_acquire+0xa47/0x2810[ 253.014303] ? srso_alias_return_thunk+0x5/0xfbef5[ 253.014321] lock_acquire+0xd1/0x300[ 253.014333] ? amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu][ 253.014562] ? __lock_acquire+0xa6b/0x2810[ 253.014578] __mutex_lock+0x85/0xe20[ 253.014591] ? amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu][ 253.014782] ? sched_clock_noinstr+0x9/0x10[ 253.014795] ? srso_alias_return_thunk+0x5/0xfbef5[ 253.014808] ? local_clock_noinstr+0xe/0xc0[ 253.014822] ? amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu][ 253.015012] ? srso_alias_return_thunk+0x5/0xfbef5[ 253.015029] mutex_lock_nested+0x1b/0x30[ 253.015044] ? mutex_lock_nested+0x1b/0x30[ 253.015057] amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu][ 253.015249] amdgpu_sriov_wreg+0xc5/0xd0 [amdgpu][ 253.015435] gmc_v11_0_flush_gpu_tlb+0x44b/0x4f0 [amdgpu][ 253.015667] gfx_v11_0_hw_init+0x499/0x29c0 [amdgpu][ 253.015901] ? __pfx_smu_v13_0_update_pcie_parameters+0x10/0x10 [amdgpu][ 253.016159] ? srso_alias_return_thunk+0x5/0xfbef5[ 253.016173] ? smu_hw_init+0x18d/0x300 [amdgpu][ 253.016403] amdgpu_device_init+0x29ad/0x36a0 [amdgpu][ 253.016614] amdgpu_driver_load_kms+0x1a/0xc0 [amdgpu][ 253.0170---truncated---

CVE-2025-38127 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ice: fix Tx scheduler error handling in XDP callbackWhen the XDP program is loaded, the XDP callback adds new Tx queues.This means that the callback must update the Tx scheduler with the newqueue number. In the event of a Tx scheduler failure, the XDP callbackshould also fail and roll back any changes previously made for XDPpreparation.The previous implementation had a bug that not all changes made by theXDP callback were rolled back. This caused the crash with the followingcall trace:[ +9.549584] ice 0000:ca:00.0: Failed VSI LAN queue config for XDP, error: -5[ +0.382335] Oops: general protection fault, probably for non-canonical address 0x50a2250a90495525: 0000 [#1] SMP NOPTI[ +0.010710] CPU: 103 UID: 0 PID: 0 Comm: swapper/103 Not tainted 6.14.0-net-next-mar-31+ #14 PREEMPT(voluntary)[ +0.010175] Hardware name: Intel Corporation M50CYP2SBSTD/M50CYP2SBSTD, BIOS SE5C620.86B.01.01.0005.2202160810 02/16/2022[ +0.010946] RIP: 0010:__ice_update_sample+0x39/0xe0 [ice][...][ +0.002715] Call Trace:[ +0.002452] [ +0.002021] ? __die_body.cold+0x19/0x29[ +0.003922] ? die_addr+0x3c/0x60[ +0.003319] ? exc_general_protection+0x17c/0x400[ +0.004707] ? asm_exc_general_protection+0x26/0x30[ +0.004879] ? __ice_update_sample+0x39/0xe0 [ice][ +0.004835] ice_napi_poll+0x665/0x680 [ice][ +0.004320] __napi_poll+0x28/0x190[ +0.003500] net_rx_action+0x198/0x360[ +0.003752] ? update_rq_clock+0x39/0x220[ +0.004013] handle_softirqs+0xf1/0x340[ +0.003840] ? sched_clock_cpu+0xf/0x1f0[ +0.003925] __irq_exit_rcu+0xc2/0xe0[ +0.003665] common_interrupt+0x85/0xa0[ +0.003839] [ +0.002098] [ +0.002106] asm_common_interrupt+0x26/0x40[ +0.004184] RIP: 0010:cpuidle_enter_state+0xd3/0x690Fix this by performing the missing unmapping of XDP queues fromq_vectors and setting the XDP rings pointer back to NULL after all thosequeues are released.Also, add an immediate exit from the XDP callback in case of ringpreparation failure.

CVE-2025-38210 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:configfs-tsm-report: Fix NULL dereference of tsm_opsUnlike sysfs, the lifetime of configfs objects is controlled byuserspace. There is no mechanism for the kernel to find and delete allcreated config-items. Instead, the configfs-tsm-report mechanism has anexpectation that tsm_unregister() can happen at any time and causeestablished config-item access to start failing.That expectation is not fully satisfied. While tsm_report_read(),tsm_report_{is,is_bin}_visible(), and tsm_report_make_item() safely failif tsm_ops have been unregistered, tsm_report_privlevel_store()tsm_report_provider_show() fail to check for ops registration. Add themissing checks for tsm_ops having been removed.Now, in supporting the ability for tsm_unregister() to always succeed,it leaves the problem of what to do with lingering config-items. Theexpectation is that the admin that arranges for the ->remove() (unbind)of the ${tsm_arch}-guest driver is also responsible for deletion of allopen config-items. Until that deletion happens, ->probe() (reload /bind) of the ${tsm_arch}-guest driver fails.This allows for emergency shutdown / revocation of attestationinterfaces, and requires coordinated restart.

Description: In the Linux kernel, the following vulnerability has been resolved:ASoC: codecs: wcd9335: Fix missing free of regulator suppliesDriver gets and enables all regulator supplies in probe path(wcd9335_parse_dt() and wcd9335_power_on_reset()), but does not cleanupin final error paths and in unbind (missing remove() callback). Thisleads to leaked memory and unbalanced regulator enable count duringprobe errors or unbind.Fix this by converting entire code into devm_regulator_bulk_get_enable()which also greatly simplifies the code.

Description: In the Linux kernel, the following vulnerability has been resolved:ptp: remove ptp->n_vclocks check logic in ptp_vclock_in_use()There is no disagreement that we should check both ptp->is_virtual_clockand ptp->n_vclocks to check if the ptp virtual clock is in use.However, when we acquire ptp->n_vclocks_mux to read ptp->n_vclocks inptp_vclock_in_use(), we observe a recursive lock in the call tracestarting from n_vclocks_store().============================================WARNING: possible recursive locking detected6.15.0-rc6 #1 Not tainted--------------------------------------------syz.0.1540/13807 is trying to acquire lock:ffff888035a24868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at: ptp_vclock_in_use drivers/ptp/ptp_private.h:103 [inline]ffff888035a24868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at: ptp_clock_unregister+0x21/0x250 drivers/ptp/ptp_clock.c:415but task is already holding lock:ffff888030704868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at: n_vclocks_store+0xf1/0x6d0 drivers/ptp/ptp_sysfs.c:215other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(&ptp->n_vclocks_mux); lock(&ptp->n_vclocks_mux); *** DEADLOCK ***....============================================The best way to solve this is to remove the logic that checksptp->n_vclocks in ptp_vclock_in_use().The reason why this is appropriate is that any path that usesptp->n_vclocks must unconditionally check if ptp->n_vclocks is greaterthan 0 before unregistering vclocks, and all functions are alreadywritten this way. And in the function that uses ptp->n_vclocks, wealready get ptp->n_vclocks_mux before unregistering vclocks.Therefore, we need to remove the redundant check for ptp->n_vclocks inptp_vclock_in_use() to prevent recursive locking.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amd/display: Add null pointer check for get_first_active_display()The function mod_hdcp_hdcp1_enable_encryption() calls the functionget_first_active_display(), but does not check its return value.The return value is a null pointer if the display list is empty.This will lead to a null pointer dereference inmod_hdcp_hdcp2_enable_encryption().Add a null pointer check for get_first_active_display() and returnMOD_HDCP_STATUS_DISPLAY_NOT_FOUND if the function return null.

CVE-2025-38386 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ACPICA: Refuse to evaluate a method if arguments are missingAs reported in [1], a platform firmware update that increased the numberof method parameters and forgot to update a least one of its callers,caused ACPICA to crash due to use-after-free.Since this a result of a clear AML issue that arguably cannot be fixedup by the interpreter (it cannot produce missing data out of thin air),address it by making ACPICA refuse to evaluate a method if the callerattempts to pass fewer arguments than expected to it.

Further debugging has allowed to narrow that scope down toDRM_IOCTL_I915_GEM_EXECBUFFER2, and ring_context_alloc(), specific to ringsubmission, in particular.If successful then that function, or its execlists or GuC submissionequivalent, is supposed to be called only once per GEM context engine,followed by raise of a flag that prevents the function from being calledagain. The function is expected to unwind its internal errors itself, soit may be safely called once more after it returns an error.In case of ring submission, the function first gets a reference to theengine's legacy timeline and then allocates a VMA. If the VMA allocationfails, e.g. when i915_vma_instance() called from inside is interruptedwith a signal, then ring_context_alloc() fails, leaving the timeline heldreferenced. On next I915_GEM_EXECBUFFER2 IOCTL, another reference to thetimeline is got, and only that last one is put on successful completion.As a consequence, the legacy timeline, with its underlying engine statuspage's VMA object, is still held and not released on driver unbind.Get the legacy timeline only after successful allocation of the contextengine's VMA.v2: Add a note on other submission methods (Krzysztof Karas): Both execlists and GuC submission use lrc_alloc() which seems free from a similar issue.(cherry picked from commit cc43422b3cc79eacff4c5a8ba0d224688ca9dd4f)

CVE-2025-38457 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: Abort __tc_modify_qdisc if parent class does not existLion's patch [1] revealed an ancient bug in the qdisc API.Whenever a user creates/modifies a qdisc specifying as a parent anotherqdisc, the qdisc API will, during grafting, detect that the user isnot trying to attach to a class and reject. However grafting isperformed after qdisc_create (and thus the qdiscs' init callback) isexecuted. In qdiscs that eventually call qdisc_tree_reduce_backlogduring init or change (such as fq, hhf, choke, etc), an issuearises. For example, executing the following commands:sudo tc qdisc add dev lo root handle a: htb default 2sudo tc qdisc add dev lo parent a: handle beef fqQdiscs such as fq, hhf, choke, etc unconditionally invokeqdisc_tree_reduce_backlog() in their control path init() or change() whichthen causes a failure to find the child class; however, that does not stopthe unconditional invocation of the assumed child qdisc's qlen_notify witha null class. All these qdiscs make the assumption that class is non-null.The solution is ensure that qdisc_leaf() which looks up the parentclass, and is invoked prior to qdisc_create(), should return failure onnot finding the class.In this patch, we leverage qdisc_leaf to return ERR_PTRs whenever theparentid doesn't correspond to a class, so that we can detect itearlier on and abort before qdisc_create is called.[1] https://lore.kernel.org/netdev/d912cbd7-193b-4269-9857-525bee8bbb6a@gmail.com/

Description: In the Linux kernel, the following vulnerability has been resolved:net: vlan: fix VLAN 0 refcount imbalance of toggling filtering during runtimeAssuming the "rx-vlan-filter" feature is enabled on a net device, the8021q module will automatically add or remove VLAN 0 when the net deviceis put administratively up or down, respectively. There are a couple ofproblems with the above scheme.The first problem is a memory leak that can happen if the "rx-vlan-filter"feature is disabled while the device is running: # ip link add bond1 up type bond mode 0 # ethtool -K bond1 rx-vlan-filter off # ip link del dev bond1When the device is put administratively down the "rx-vlan-filter"feature is disabled, so the 8021q module will not remove VLAN 0 and thememory will be leaked [1].Another problem that can happen is that the kernel can automaticallydelete VLAN 0 when the device is put administratively down despite notadding it when the device was put administratively up since during thattime the "rx-vlan-filter" feature was disabled. null-ptr-unref orbug_on[2] will be triggered by unregister_vlan_dev() for refcountimbalance if toggling filtering during runtime:$ ip link add bond0 type bond mode 0$ ip link add link bond0 name vlan0 type vlan id 0 protocol 802.1q$ ethtool -K bond0 rx-vlan-filter off$ ifconfig bond0 up$ ethtool -K bond0 rx-vlan-filter on$ ifconfig bond0 down$ ip link del vlan0Root cause is as below:step1: add vlan0 for real_dev, such as bond, team.register_vlan_dev vlan_vid_add(real_dev,htons(ETH_P_8021Q),0) //refcnt=1step2: disable vlan filter feature and enable real_devstep3: change filter from 0 to 1vlan_device_event vlan_filter_push_vids ndo_vlan_rx_add_vid //No refcnt added to real_dev vlan0step4: real_dev downvlan_device_event vlan_vid_del(dev, htons(ETH_P_8021Q), 0); //refcnt=0 vlan_info_rcu_free //free vlan0step5: delete vlan0unregister_vlan_dev BUG_ON(!vlan_info); //vlan_info is nullFix both problems by noting in the VLAN info whether VLAN 0 wasautomatically added upon NETDEV_UP and based on that decide whether itshould be deleted upon NETDEV_DOWN, regardless of the state of the"rx-vlan-filter" feature.[1]unreferenced object 0xffff8880068e3100 (size 256): comm "ip", pid 384, jiffies 4296130254 hex dump (first 32 bytes): 00 20 30 0d 80 88 ff ff 00 00 00 00 00 00 00 00 . 0............. 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace (crc 81ce31fa): __kmalloc_cache_noprof+0x2b5/0x340 vlan_vid_add+0x434/0x940 vlan_device_event.cold+0x75/0xa8 notifier_call_chain+0xca/0x150 __dev_notify_flags+0xe3/0x250 rtnl_configure_link+0x193/0x260 rtnl_newlink_create+0x383/0x8e0 __rtnl_newlink+0x22c/0xa40 rtnl_newlink+0x627/0xb00 rtnetlink_rcv_msg+0x6fb/0xb70 netlink_rcv_skb+0x11f/0x350 netlink_unicast+0x426/0x710 netlink_sendmsg+0x75a/0xc20 __sock_sendmsg+0xc1/0x150 ____sys_sendmsg+0x5aa/0x7b0 ___sys_sendmsg+0xfc/0x180[2]kernel BUG at net/8021q/vlan.c:99!Oops: invalid opcode: 0000 [#1] SMP KASAN PTICPU: 0 UID: 0 PID: 382 Comm: ip Not tainted 6.16.0-rc3 #61 PREEMPT(voluntary)Hardware name: QEMU Standard PC (i440FX + PIIX, 1996),BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014RIP: 0010:unregister_vlan_dev (net/8021q/vlan.c:99 (discriminator 1))RSP: 0018:ffff88810badf310 EFLAGS: 00010246RAX: 0000000000000000 RBX: ffff88810da84000 RCX: ffffffffb47ceb9aRDX: dffffc0000000000 RSI: 0000000000000008 RDI: ffff88810e8b43c8RBP: 0000000000000000 R08: 0000000000000000 R09: fffffbfff6cefe80R10: ffffffffb677f407 R11: ffff88810badf3c0 R12: ffff88810e8b4000R13: 0000000000000000 R14: ffff88810642a5c0 R15: 000000000000017eFS: 00007f1ff68c20c0(0000) GS:ffff888163a24000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007f1ff5dad240 CR3: 0000000107e56000 CR4: 00000000000006f0Call Trace:

It also meansthis is the block group with the highest start offset, so there are nohigher keys in the extent root, hence btrfs_search_slot_for_read()returns 1 (no higher key found).Fix this by asserting 'ret' is 0 only if the block group tree featureis not enabled, in which case we should find a block group item forthe block group since it's stored in the extent root and block groupitem keys are greater than extent item keys (the value forBTRFS_BLOCK_GROUP_ITEM_KEY is 192 and for BTRFS_EXTENT_ITEM_KEY andBTRFS_METADATA_ITEM_KEY the values are 168 and 169 respectively).In case 'ret' is 1, we just need to add a record to the free spacetree which spans the whole block group, and we can achieve this bymaking 'ret == 0' as the while loop's condition.

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

Description: In the Linux kernel, the following vulnerability has been resolved:pinctrl: qcom: msm: mark certain pins as invalid for interruptsOn some platforms, the UFS-reset pin has no interrupt logic in TLMM butis nevertheless registered as a GPIO in the kernel. This enables theuser-space to trigger a BUG() in the pinctrl-msm driver by running, forexample: `gpiomon -c 0 113` on RB2.The exact culprit is requesting pins whose intr_detection_width settingis not 1 or 2 for interrupts. This hits a BUG() inmsm_gpio_irq_set_type(). Potentially crashing the kernel due to aninvalid request from user-space is not optimal, so let's go through thepins and mark those that would fail the check as invalid for the irq chipas we should not even register them as available irqs.This function can be extended if we determine that there are morecorner-cases like this.

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: Fix recv-recv race of completed callIf a call receives an event (such as incoming data), the call gets placedon the socket's queue and a thread in recvmsg can be awakened to go andprocess it. Once the thread has picked up the call off of the queue,further events will cause it to be requeued, and once the socket lock isdropped (recvmsg uses call->user_mutex to allow the socket to be used inparallel), a second thread can come in and its recvmsg can pop the call offthe socket queue again.In such a case, the first thread will be receiving stuff from the call andthe second thread will be blocked on call->user_mutex. The first threadcan, at this point, process both the event that it picked call for and theevent that the second thread picked the call for and may see the callterminate - in which case the call will be "released", decoupling the callfrom the user call ID assigned to it (RXRPC_USER_CALL_ID in the controlmessage).The first thread will return okay, but then the second thread will wake upholding the user_mutex and, if it sees that the call has been released bythe first thread, it will BUG thusly: kernel BUG at net/rxrpc/recvmsg.c:474!Fix this by just dequeuing the call and ignoring it if it is seen to bealready released. We can't tell userspace about it anyway as the user callID has become stale.

However, if the regulatoris marked as always-on, regulator_is_enabled() continues to return true,leading to an incorrect attempt to disable a regulator which is notenabled.This can result in warnings such as:[ 250.155624] WARNING: CPU: 1 PID: 7326 at drivers/regulator/core.c:3004_regulator_disable+0xe4/0x1a0[ 250.155652] unbalanced disables for VIN_SYS_5V0To fix this, we move the regulator control logic intotegra186_xusb_padctl_id_override() function since it's directly relatedto the ID override state. The regulator is now only disabled when the roletransitions from USB_ROLE_HOST to USB_ROLE_NONE, by checking the VBUS_IDregister. This ensures that regulator enable/disable operations areproperly balanced and only occur when actually transitioning to/from hostmode.

CVE-2025-38590 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5e: Remove skb secpath if xfrm state is not foundHardware returns a unique identifier for a decrypted packet's xfrmstate, this state is looked up in an xarray. However, the state mighthave been freed by the time of this lookup.Currently, if the state is not found, only a counter is incremented.The secpath (sp) extension on the skb is not removed, resulting insp->len becoming 0.Subsequently, functions like __xfrm_policy_check() attempt to accessfields such as xfrm_input_state(skb)->xso.type (which dereferencessp->xvec[sp->len - 1]) without first validating sp->len. This leads toa crash when dereferencing an invalid state pointer.This patch prevents the crash by explicitly removing the secpathextension from the skb if the xfrm state is not found after hardwaredecryption. This ensures downstream functions do not operate on azero-length secpath.

CVE-2025-38614 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:eventpoll: Fix semi-unbounded recursionEnsure that epoll instances can never form a graph deeper thanEP_MAX_NESTS+1 links.Currently, ep_loop_check_proc() ensures that the graph is loop-free anddoes some recursion depth checks, but those recursion depth checks don'tlimit the depth of the resulting tree for two reasons: - They don't look upwards in the tree. - If there are multiple downwards paths of different lengths, only one of the paths is actually considered for the depth check since commit 28d82dc1c4ed ("epoll: limit paths").Essentially, the current recursion depth check in ep_loop_check_proc() justserves to prevent it from recursing too deeply while checking for loops.A more thorough check is done in reverse_path_check() after the new graphedge has already been created; this checks, among other things, that nopaths going upwards from any non-epoll file with a length of more than 5edges exist. However, this check does not apply to non-epoll files.As a result, it is possible to recurse to a depth of at least roughly 500,tested on v6.15. (I am unsure if deeper recursion is possible; and this mayhave changed with commit 8c44dac8add7 ("eventpoll: Fix priority inversionproblem").)To fix it:1. In ep_loop_check_proc(), note the subtree depth of each visited node,and use subtree depths for the total depth calculation even when a subtreehas already been visited.2. Add ep_get_upwards_depth_proc() for similarly determining the maximumdepth of an upwards walk.3. In ep_loop_check(), use these values to limit the total path lengthbetween epoll nodes to EP_MAX_NESTS edges.

This is required since pnv_php_disable_irq() willnow be called by workers triggered by hot unplug interrupts, so theworkqueue needs to stay allocated.The abridged kernel panic that occurs without this patch is as follows: WARNING: CPU: 0 PID: 687 at kernel/irq/msi.c:292 msi_device_data_release+0x6c/0x9c CPU: 0 UID: 0 PID: 687 Comm: bash Not tainted 6.14.0-rc5+ #2 Call Trace: msi_device_data_release+0x34/0x9c (unreliable) release_nodes+0x64/0x13c devres_release_all+0xc0/0x140 device_del+0x2d4/0x46c pci_destroy_dev+0x5c/0x194 pci_hp_remove_devices+0x90/0x128 pci_hp_remove_devices+0x44/0x128 pnv_php_disable_slot+0x54/0xd4 power_write_file+0xf8/0x18c pci_slot_attr_store+0x40/0x5c sysfs_kf_write+0x64/0x78 kernfs_fop_write_iter+0x1b0/0x290 vfs_write+0x3bc/0x50c ksys_write+0x84/0x140 system_call_exception+0x124/0x230 system_call_vectored_common+0x15c/0x2ec[bhelgaas: tidy comments]

CVE-2025-38670 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:arm64/entry: Mask DAIF in cpu_switch_to(), call_on_irq_stack()`cpu_switch_to()` and `call_on_irq_stack()` manipulate SP to changeto different stacks along with the Shadow Call Stack if it is enabled.Those two stack changes cannot be done atomically and both functionscan be interrupted by SErrors or Debug Exceptions which, though unlikely,is very much broken : if interrupted, we can end up with mismatched stacksand Shadow Call Stack leading to clobbered stacks.In `cpu_switch_to()`, it can happen when SP_EL0 points to the new task,but x18 stills points to the old task's SCS. When the interrupt handlertries to save the task's SCS pointer, it will save the old taskSCS pointer (x18) into the new task struct (pointed to by SP_EL0),clobbering it.In `call_on_irq_stack()`, it can happen when switching from the task stackto the IRQ stack and when switching back. In both cases, we can beinterrupted when the SCS pointer points to the IRQ SCS, but SP points tothe task stack. The nested interrupt handler pushes its return addresseson the IRQ SCS. It then detects that SP points to the task stack,calls `call_on_irq_stack()` and clobbers the task SCS pointer withthe IRQ SCS pointer, which it will also use !This leads to tasks returning to addresses on the wrong SCS,or even on the IRQ SCS, triggering kernel panics via CONFIG_VMAP_STACKor FPAC if enabled.This is possible on a default config, but unlikely.However, when enabling CONFIG_ARM64_PSEUDO_NMI, DAIF is unmasked andinstead the GIC is responsible for filtering what interrupts the CPUshould receive based on priority.Given the goal of emulating NMIs, pseudo-NMIs can be received by the CPUeven in `cpu_switch_to()` and `call_on_irq_stack()`, possibly *very*frequently depending on the system configuration and workload, leadingto unpredictable kernel panics.Completely mask DAIF in `cpu_switch_to()` and restore it when returning.Do the same in `call_on_irq_stack()`, but restore and mask aroundthe branch.Mask DAIF even if CONFIG_SHADOW_CALL_STACK is not enabled for consistencyof behaviour between all configurations.Introduce and use an assembly macro for saving and masking DAIF,as the existing one saves but only masks IF.

Description: In the Linux kernel, the following vulnerability has been resolved:i2c: qup: jump out of the loop in case of timeoutOriginal logic only sets the return value but doesn't jump out of theloop if the bus is kept active by a client.

This is observed during a long time test with aPCA953x GPIO extender.Fix it by changing the logic to not only sets the return value, but alsojumps out of the loop and return to the caller with -ETIMEDOUT.

CVE-2025-38681 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm/ptdump: take the memory hotplug lock inside ptdump_walk_pgd()Memory hot remove unmaps and tears down various kernel page table regionsas required. The ptdump code can race with concurrent modifications ofthe kernel page tables. When leaf entries are modified concurrently, thedump code may log stale or inconsistent information for a VA range, butthis is otherwise not harmful.But when intermediate levels of kernel page table are freed, the dump codewill continue to use memory that has been freed and potentiallyreallocated for another purpose. In such cases, the ptdump code maydereference bogus addresses, leading to a number of potential problems.To avoid the above mentioned race condition, platforms such as arm64,riscv and s390 take memory hotplug lock, while dumping kernel page tablevia the sysfs interface /sys/kernel/debug/kernel_page_tables.Similar race condition exists while checking for pages that might havebeen marked W+X via /sys/kernel/debug/kernel_page_tables/check_wx_pageswhich in turn calls ptdump_check_wx(). Instead of solving this racecondition again, let's just move the memory hotplug lock inside genericptdump_check_wx() which will benefit both the scenarios.Drop get_online_mems() and put_online_mems() combination from all existingplatform ptdump code paths.

CVE-2025-38687 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: fix race between polling and detachingsyzbot reports a use-after-free in comedi in the below link, which isdue to comedi gladly removing the allocated async area even though pollrequests are still active on the wait_queue_head inside of it. This cancause a use-after-free when the poll entries are later triggered orremoved, as the memory for the wait_queue_head has been freed. We needto check there are no tasks queued on any of the subdevices' wait queuesbefore allowing the device to be detached by the `COMEDI_DEVCONFIG`ioctl.Tasks will read-lock `dev->attach_lock` before adding themselves to thesubdevice wait queue, so fix the problem in the `COMEDI_DEVCONFIG` ioctlhandler by write-locking `dev->attach_lock` before checking that all ofthe subdevices are safe to be deleted. This includes testing for anysleepers on the subdevices' wait queues. It remains locked until thedevice has been detached. This requires the `comedi_device_detach()`function to be refactored slightly, moving the bulk of it into newfunction `comedi_device_detach_locked()`.Note that the refactor of `comedi_device_detach()` results in`comedi_device_cancel_all()` now being called while `dev->attach_lock`is write-locked, which wasn't the case previously, but that does notmatter.Thanks to Jens Axboe for diagnosing the problem and co-developing thispatch.

CVE-2025-38691 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:pNFS: Fix uninited ptr deref in block/scsi layoutThe error occurs on the third attempt to encode extents. When functionext_tree_prepare_commit() reallocates a larger buffer to retry encodingextents, the "layoutupdate_pages" page array is initialized only after theretry loop. But ext_tree_free_commitdata() is called on every iterationand tries to put pages in the array, thus dereferencing uninitializedpointers.An additional problem is that there is no limit on the maximum possiblebuffer_size. When there are too many extents, the client may create alayoutcommit that is larger than the maximum possible RPC size acceptedby the server.During testing, we observed two typical scenarios. First, one memory pagefor extents is enough when we work with small files, append data to theend of the file, or preallocate extents before writing. But when we filla new large file without preallocating, the number of extents can be huge,and counting the number of written extents in ext_tree_encode_commit()does not help much. Since this number increases even more betweenunlocking and locking of ext_tree, the reallocated buffer may not belarge enough again and again.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: ctnetlink: fix refcount leak on table dumpThere is a reference count leak in ctnetlink_dump_table(): if (res < 0) { nf_conntrack_get(&ct->ct_general); // HERE cb->args[1] = (unsigned long)ct; ...While its very unlikely, its possible that ct == last.If this happens, then the refcount of ct was already incremented.This 2nd increment is never undone.This prevents the conntrack object from being released, which in turnkeeps prevents cnet->count from dropping back to 0.This will then block the netns dismantle (or conntrack rmmod) asnf_conntrack_cleanup_net_list() will wait forever.This can be reproduced by running conntrack_resize.sh selftest in a loop.It takes ~20 minutes for me on a preemptible kernel on average beforeI see a runaway kworker spinning in nf_conntrack_cleanup_net_list.One fix would to change this to: if (res < 0) { if (ct != last) nf_conntrack_get(&ct->ct_general);But this reference counting isn't needed in the first place.We can just store a cookie value instead.A followup patch will do the same for ctnetlink_exp_dump_table,it looks to me as if this has the same problem and likectnetlink_dump_table, we only need a 'skip hint', not the actualobject so we can apply the same cookie strategy there as well.

CVE-2025-38722 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:habanalabs: fix UAF in export_dmabuf()As soon as we'd inserted a file reference into descriptor table, anotherthread could close it. That's fine for the case when all we are doing isreturning that descriptor to userland (it's a race, but it's a userlandrace and there's nothing the kernel can do about it). However, if wefollow fd_install() with any kind of access to objects that would bedestroyed on close (be it the struct file itself or anything destroyedby its ->release()), we have a UAF.dma_buf_fd() is a combination of reserving a descriptor and fd_install().habanalabs export_dmabuf() calls it and then proceeds to access theobjects destroyed on close. In particular, it grabs an extra reference toanother struct file that will be dropped as part of ->release() for ours;that "will be" is actually "might have already been".Fix that by reserving descriptor before anything else and do fd_install()only when everything had been set up. As a side benefit, we no longerhave the failure exit with file already created, but reference tounderlying file (as well as ->dmabuf_export_cnt, etc.) not grabbed yet;unlike dma_buf_fd(), fd_install() can't fail.

Description: In the Linux kernel, the following vulnerability has been resolved:nfsd: handle get_client_locked() failure in nfsd4_setclientid_confirm()Lei Lu recently reported that nfsd4_setclientid_confirm() did not checkthe return value from get_client_locked(). a SETCLIENTID_CONFIRM couldrace with a confirmed client expiring and fail to get a reference. Thatcould later lead to a UAF.Fix this by getting a reference early in the case where there is anextant confirmed client.

CVE-2025-38730 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring/net: commit partial buffers on retryRing provided buffers are potentially only valid within the singleexecution context in which they were acquired. io_uring deals with thisand invalidates them on retry. But on the networking side, ifMSG_WAITALL is set, or if the socket is of the streaming type and toolittle was processed, then it will hang on to the buffer rather thanrecycle or commit it. This is problematic for two reasons:1) If someone unregisters the provided buffer ring before a later retry, then the req->buf_list will no longer be valid.2) If multiple sockers are using the same buffer group, then multiple receives can consume the same memory. This can cause data corruption in the application, as either receive could land in the same userspace buffer.Fix this by disallowing partial retries from pinning a provided bufferacross multiple executions, if ring provided buffers are used.

Description: In the Linux kernel, the following vulnerability has been resolved:s390/mm: Do not map lowcore with identity mappingSince the identity mapping is pinned to address zero the lowcore is alwaysalso mapped to address zero, this happens regardless of the relocate_lowcorecommand line option. If the option is specified the lowcore is mappedtwice, instead of only once.This means that NULL pointer accesses will succeed instead of causing anexception (low address protection still applies, but covers only parts).To fix this never map the first two pages of physical memory with theidentity mapping.

CVE-2025-38735 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:gve: prevent ethtool ops after shutdownA crash can occur if an ethtool operation is invokedafter shutdown() is called.shutdown() is invoked during system shutdown to stop DMA operationswithout performing expensive deallocations. It is discouraged tounregister the netdev in this path, so the device may still be visibleto userspace and kernel helpers.In gve, shutdown() tears down most internal data structures. If anethtool operation is dispatched after shutdown(), it will dereferencefreed or NULL pointers, leading to a kernel panic. While gracefulshutdown normally quiesces userspace before invoking the rebootsyscall, forced shutdowns (as observed on GCP VMs) can still triggerthis path.Fix by calling netif_device_detach() in shutdown().This marks the device as detached so the ethtool ioctl handlerwill skip dispatching operations to the driver.

CVE-2025-39673 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ppp: fix race conditions in ppp_fill_forward_pathppp_fill_forward_path() has two race conditions:1. The ppp->channels list can change between list_empty() and list_first_entry(), as ppp_lock() is not held. If the only channel is deleted in ppp_disconnect_channel(), list_first_entry() may access an empty head or a freed entry, and trigger a panic.2. pch->chan can be NULL. When ppp_unregister_channel() is called, pch->chan is set to NULL before pch is removed from ppp->channels.Fix these by using a lockless RCU approach:- Use list_first_or_null_rcu() to safely test and access the first list entry.- Convert list modifications on ppp->channels to their RCU variants and add synchronize_net() after removal.- Check for a NULL pch->chan before dereferencing it.

CVE-2025-39677 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: Fix backlog accounting in qdisc_dequeue_internalThis issue applies for the following qdiscs: hhf, fq, fq_codel, andfq_pie, and occurs in their change handlers when adjusting to the newlimit. The problem is the following in the values passed to thesubsequent qdisc_tree_reduce_backlog call given a tbf parent: When the tbf parent runs out of tokens, skbs of these qdiscs will be placed in gso_skb. Their peek handlers are qdisc_peek_dequeued, which accounts for both qlen and backlog. However, in the case of qdisc_dequeue_internal, ONLY qlen is accounted for when pulling from gso_skb. This means that these qdiscs are missing a qdisc_qstats_backlog_dec when dropping packets to satisfy the new limit in their change handlers. One can observe this issue with the following (with tc patched to support a limit of 0): export TARGET=fq tc qdisc del dev lo root tc qdisc add dev lo root handle 1: tbf rate 8bit burst 100b latency 1ms tc qdisc replace dev lo handle 3: parent 1:1 $TARGET limit 1000 echo ''; echo 'add child'; tc -s -d qdisc show dev lo ping -I lo -f -c2 -s32 -W0.001 127.0.0.1 2>&1 >/dev/null echo ''; echo 'after ping'; tc -s -d qdisc show dev lo tc qdisc change dev lo handle 3: parent 1:1 $TARGET limit 0 echo ''; echo 'after limit drop'; tc -s -d qdisc show dev lo tc qdisc replace dev lo handle 2: parent 1:1 sfq echo ''; echo 'post graft'; tc -s -d qdisc show dev lo The second to last show command shows 0 packets but a positive number (74) of backlog bytes. The problem becomes clearer in the last show command, where qdisc_purge_queue triggers qdisc_tree_reduce_backlog with the positive backlog and causes an underflow in the tbf parent's backlog (4096 Mb instead of 0).To fix this issue, the codepath for all clients of qdisc_dequeue_internalhas been simplified: codel, pie, hhf, fq, fq_pie, and fq_codel.qdisc_dequeue_internal handles the backlog adjustments for all cases thatdo not directly use the dequeue handler.The old fq_codel_change limit adjustment loop accumulated the arguments tothe subsequent qdisc_tree_reduce_backlog call through the cstats field.However, this is confusing and error prone as fq_codel_dequeue could alsopotentially mutate this field (which qdisc_dequeue_internal calls in thenon gso_skb case), so we have unified the code here with other qdiscs.

CVE-2025-39684 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: Fix use of uninitialized memory in do_insn_ioctl() and do_insnlist_ioctl()syzbot reports a KMSAN kernel-infoleak in `do_insn_ioctl()`. A kernelbuffer is allocated to hold `insn->n` samples (each of which is an`unsigned int`). For some instruction types, `insn->n` samples arecopied back to user-space, unless an error code is being returned. Theproblem is that not all the instruction handlers that need to returndata to userspace fill in the whole `insn->n` samples, so that there isan information leak. There is a similar syzbot report for`do_insnlist_ioctl()`, although it does not have a reproducer for it atthe time of writing.One culprit is `insn_rw_emulate_bits()` which is used as the handler for`INSN_READ` or `INSN_WRITE` instructions for subdevices that do not havea specific handler for that instruction, but do have an `INSN_BITS`handler. For `INSN_READ` it only fills in at most 1 sample, so if`insn->n` is greater than 1, the remaining `insn->n - 1` samples copiedto userspace will be uninitialized kernel data.Another culprit is `vm80xx_ai_insn_read()` in the "vm80xx" driver. Itnever returns an error, even if it fails to fill the buffer.Fix it in `do_insn_ioctl()` and `do_insnlist_ioctl()` by making surethat uninitialized parts of the allocated buffer are zeroed beforehandling each instruction.Thanks to Arnaud Lecomte for their fix to `do_insn_ioctl()`. That fixreplaced the call to `kmalloc_array()` with `kcalloc()`, but it is notalways necessary to clear the whole buffer.

CVE-2025-39686 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: Make insn_rw_emulate_bits() do insn->n samplesThe `insn_rw_emulate_bits()` function is used as a default handler for`INSN_READ` instructions for subdevices that have a handler for`INSN_BITS` but not for `INSN_READ`. Similarly, it is used as a defaulthandler for `INSN_WRITE` instructions for subdevices that have a handlerfor `INSN_BITS` but not for `INSN_WRITE`. It works by emulating the`INSN_READ` or `INSN_WRITE` instruction handling with a constructed`INSN_BITS` instruction. However, `INSN_READ` and `INSN_WRITE`instructions are supposed to be able read or write multiple samples,indicated by the `insn->n` value, but `insn_rw_emulate_bits()` currentlyonly handles a single sample. For `INSN_READ`, the comedi core willcopy `insn->n` samples back to user-space. (That triggered KASANkernel-infoleak errors when `insn->n` was greater than 1, but that isbeing fixed more generally elsewhere in the comedi core.)Make `insn_rw_emulate_bits()` either handle `insn->n` samples, or returnan error, to conform to the general expectation for `INSN_READ` and`INSN_WRITE` handlers.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:media: rainshadow-cec: fix TOCTOU race condition in rain_interrupt()In the interrupt handler rain_interrupt(), the buffer full check onrain->buf_len is performed before acquiring rain->buf_lock. Thiscreates a Time-of-Check to Time-of-Use (TOCTOU) race condition, asrain->buf_len is concurrently accessed and modified in the workhandler rain_irq_work_handler() under the same lock.Multiple interrupt invocations can race, with each reading buf_lenbefore it becomes full and then proceeding. This can lead to bothinterrupts attempting to write to the buffer, incrementing buf_lenbeyond its capacity (DATA_SIZE) and causing a buffer overflow.Fix this bug by moving the spin_lock() to before the buffer fullcheck. This ensures that the check and the subsequent buffer modificationare performed atomically, preventing the race condition. An correspondingspin_unlock() is added to the overflow path to correctly release thelock.This possible bug was found by an experimental static analysis tooldeveloped by our team.

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: qat - flush misc workqueue during device shutdownRepeated loading and unloading of a device specific QAT driver, forexample qat_4xxx, in a tight loop can lead to a crash due to ause-after-free scenario. This occurs when a power management (PM)interrupt triggers just before the device-specific driver (e.g.,qat_4xxx.ko) is unloaded, while the core driver (intel_qat.ko) remainsloaded.Since the driver uses a shared workqueue (`qat_misc_wq`) across alldevices and owned by intel_qat.ko, a deferred routine from thedevice-specific driver may still be pending in the queue. If thisroutine executes after the driver is unloaded, it can dereference freedmemory, resulting in a page fault and kernel crash like the following: BUG: unable to handle page fault for address: ffa000002e50a01c #PF: supervisor read access in kernel mode RIP: 0010:pm_bh_handler+0x1d2/0x250 [intel_qat] Call Trace: pm_bh_handler+0x1d2/0x250 [intel_qat] process_one_work+0x171/0x340 worker_thread+0x277/0x3a0 kthread+0xf0/0x120 ret_from_fork+0x2d/0x50To prevent this, flush the misc workqueue during device shutdown toensure that all pending work items are completed before the driver isunloaded.Note: This approach may slightly increase shutdown latency if theworkqueue contains jobs from other devices, but it ensures correctnessand stability.

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: caam - Prevent crash on suspend with iMX8QM / iMX8ULPSince the CAAM on these SoCs is managed by another ARM core, called theSECO (Security Controller) on iMX8QM and Secure Enclave on iMX8ULP, whichalso reserves access to register page 0 suspend operations cannot touchthis page.This is similar to when running OPTEE, where OPTEE will reserve page 0.Track this situation using a new state variable no_page0, reflecting ifpage 0 is reserved elsewhere, either by other management cores in SoC orby OPTEE.Replace the optee_en check in suspend/resume with the new check.optee_en cannot go away as it's needed elsewhere to gate OPTEE specificsituations.Fixes the following splat at suspend: Internal error: synchronous external abort: 0000000096000010 [#1] SMP Hardware name: Freescale i.MX8QXP ACU6C (DT) pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : readl+0x0/0x18 lr : rd_reg32+0x18/0x3c sp : ffffffc08192ba20 x29: ffffffc08192ba20 x28: ffffff8025190000 x27: 0000000000000000 x26: ffffffc0808ae808 x25: ffffffc080922338 x24: ffffff8020e89090 x23: 0000000000000000 x22: ffffffc080922000 x21: ffffff8020e89010 x20: ffffffc080387ef8 x19: ffffff8020e89010 x18: 000000005d8000d5 x17: 0000000030f35963 x16: 000000008f785f3f x15: 000000003b8ef57c x14: 00000000c418aef8 x13: 00000000f5fea526 x12: 0000000000000001 x11: 0000000000000002 x10: 0000000000000001 x9 : 0000000000000000 x8 : ffffff8025190870 x7 : ffffff8021726880 x6 : 0000000000000002 x5 : ffffff80217268f0 x4 : ffffff8021726880 x3 : ffffffc081200000 x2 : 0000000000000001 x1 : ffffff8020e89010 x0 : ffffffc081200004 Call trace: readl+0x0/0x18 caam_ctrl_suspend+0x30/0xdc dpm_run_callback.constprop.0+0x24/0x5c device_suspend+0x170/0x2e8 dpm_suspend+0xa0/0x104 dpm_suspend_start+0x48/0x50 suspend_devices_and_enter+0x7c/0x45c pm_suspend+0x148/0x160 state_store+0xb4/0xf8 kobj_attr_store+0x14/0x24 sysfs_kf_write+0x38/0x48 kernfs_fop_write_iter+0xb4/0x178 vfs_write+0x118/0x178 ksys_write+0x6c/0xd0 __arm64_sys_write+0x14/0x1c invoke_syscall.constprop.0+0x64/0xb0 do_el0_svc+0x90/0xb0 el0_svc+0x18/0x44 el0t_64_sync_handler+0x88/0x124 el0t_64_sync+0x150/0x154 Code: 88dffc21 88dffc21 5ac00800 d65f03c0 (b9400000)

CVE-2025-39723 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:netfs: Fix unbuffered write error handlingIf all the subrequests in an unbuffered write stream fail, the subrequestcollector doesn't update the stream->transferred value and it retains itsinitial LONG_MAX value. Unfortunately, if all active streams fail, then wetake the smallest value of { LONG_MAX, LONG_MAX, ... } as the value to setin wreq->transferred - which is then returned from ->write_iter().LONG_MAX was chosen as the initial value so that all the streams can bequickly assessed by taking the smallest value of all stream->transferred -but this only works if we've set any of them.Fix this by adding a flag to indicate whether the value instream->transferred is valid and checking that when we integrate thevalues. stream->transferred can then be initialised to zero.This was found by running the generic/750 xfstest against cifs withcache=none. It splices data to the target file. Once (if) it has used upall the available scratch space, the writes start failing with ENOSPC.This causes ->write_iter() to fail. However, it was returningwreq->transferred, i.e. LONG_MAX, rather than an error (because it thoughtthe amount transferred was non-zero) and iter_file_splice_write() wouldthen try to clean up that amount of pipe bufferage - leading to an oopswhen it overran. The kernel log showed: CIFS: VFS: Send error in write = -28followed by: BUG: kernel NULL pointer dereference, address: 0000000000000008with: RIP: 0010:iter_file_splice_write+0x3a4/0x520 do_splice+0x197/0x4e0or: RIP: 0010:pipe_buf_release (include/linux/pipe_fs_i.h:282) iter_file_splice_write (fs/splice.c:755)Also put a warning check into splice to announce if ->write_iter() returnedthat it had written more than it was asked to.

Description: In the Linux kernel, the following vulnerability has been resolved:serial: 8250: fix panic due to PSLVERRWhen the PSLVERR_RESP_EN parameter is set to 1, the device generatesan error response if an attempt is made to read an empty RBR (ReceiveBuffer Register) while the FIFO is enabled.In serial8250_do_startup(), calling serial_port_out(port, UART_LCR,UART_LCR_WLEN8) triggers dw8250_check_lcr(), which invokesdw8250_force_idle() and serial8250_clear_and_reinit_fifos(). The latterfunction enables the FIFO via serial_out(p, UART_FCR, p->fcr).Execution proceeds to the serial_port_in(port, UART_RX).This satisfies the PSLVERR trigger condition.When another CPU (e.g., using printk()) is accessing the UART (UARTis busy), the current CPU fails the check (value & ~UART_LCR_SPAR) ==(lcr & ~UART_LCR_SPAR) in dw8250_check_lcr(), causing it to enterdw8250_force_idle().Put serial_port_out(port, UART_LCR, UART_LCR_WLEN8) under the port->lockto fix this issue.Panic backtrace:[ 0.442336] Oops - unknown exception [#1][ 0.442343] epc : dw8250_serial_in32+0x1e/0x4a[ 0.442351] ra : serial8250_do_startup+0x2c8/0x88e...[ 0.442416] console_on_rootfs+0x26/0x70

CVE-2025-39749 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:rcu: Protect ->defer_qs_iw_pending from data raceOn kernels built with CONFIG_IRQ_WORK=y, when rcu_read_unlock() isinvoked within an interrupts-disabled region of code [1], it will invokercu_read_unlock_special(), which uses an irq-work handler to force thesystem to notice when the RCU read-side critical section actually ends.That end won't happen until interrupts are enabled at the soonest.In some kernels, such as those booted with rcutree.use_softirq=y, theirq-work handler is used unconditionally.The per-CPU rcu_data structure's ->defer_qs_iw_pending field isupdated by the irq-work handler and is both read and updated byrcu_read_unlock_special(). This resulted in the following KCSAN splat:------------------------------------------------------------------------BUG: KCSAN: data-race in rcu_preempt_deferred_qs_handler / rcu_read_unlock_specialread to 0xffff96b95f42d8d8 of 1 bytes by task 90 on cpu 8: rcu_read_unlock_special+0x175/0x260 __rcu_read_unlock+0x92/0xa0 rt_spin_unlock+0x9b/0xc0 __local_bh_enable+0x10d/0x170 __local_bh_enable_ip+0xfb/0x150 rcu_do_batch+0x595/0xc40 rcu_cpu_kthread+0x4e9/0x830 smpboot_thread_fn+0x24d/0x3b0 kthread+0x3bd/0x410 ret_from_fork+0x35/0x40 ret_from_fork_asm+0x1a/0x30write to 0xffff96b95f42d8d8 of 1 bytes by task 88 on cpu 8: rcu_preempt_deferred_qs_handler+0x1e/0x30 irq_work_single+0xaf/0x160 run_irq_workd+0x91/0xc0 smpboot_thread_fn+0x24d/0x3b0 kthread+0x3bd/0x410 ret_from_fork+0x35/0x40 ret_from_fork_asm+0x1a/0x30no locks held by irq_work/8/88.irq event stamp: 200272hardirqs last enabled at (200272): [] finish_task_switch+0x131/0x320hardirqs last disabled at (200271): [] __schedule+0x129/0xd70softirqs last enabled at (0): [] copy_process+0x4df/0x1cc0softirqs last disabled at (0): [<0000000000000000>] 0x0------------------------------------------------------------------------The problem is that irq-work handlers run with interrupts enabled, whichmeans that rcu_preempt_deferred_qs_handler() could be interrupted,and that interrupt handler might contain an RCU read-side criticalsection, which might invoke rcu_read_unlock_special(). In the strictKCSAN mode of operation used by RCU, this constitutes a data race onthe ->defer_qs_iw_pending field.This commit therefore disables interrupts across the portion of thercu_preempt_deferred_qs_handler() that updates the ->defer_qs_iw_pendingfield. This suffices because this handler is not a fast path.

CVE-2025-39756 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fs: Prevent file descriptor table allocations exceeding INT_MAXWhen sysctl_nr_open is set to a very high value (for example, 1073741816as set by systemd), processes attempting to use file descriptors nearthe limit can trigger massive memory allocation attempts that exceedINT_MAX, resulting in a WARNING in mm/slub.c: WARNING: CPU: 0 PID: 44 at mm/slub.c:5027 __kvmalloc_node_noprof+0x21a/0x288This happens because kvmalloc_array() and kvmalloc() check if therequested size exceeds INT_MAX and emit a warning when the allocation isnot flagged with __GFP_NOWARN.Specifically, when nr_open is set to 1073741816 (0x3ffffff8) and aprocess calls dup2(oldfd, 1073741880), the kernel attempts to allocate:- File descriptor array: 1073741880 * 8 bytes = 8,589,935,040 bytes- Multiple bitmaps: ~400MB- Total allocation size: > 8GB (exceeding INT_MAX = 2,147,483,647)Reproducer:1. Set /proc/sys/fs/nr_open to 1073741816: # echo 1073741816 > /proc/sys/fs/nr_open2. Run a program that uses a high file descriptor: #include #include int main() { struct rlimit rlim = {1073741824, 1073741824}; setrlimit(RLIMIT_NOFILE, &rlim); dup2(2, 1073741880); // Triggers the warning return 0; }3. Observe WARNING in dmesg at mm/slub.c:5027systemd commit a8b627a introduced automatic bumping of fs.nr_open to themaximum possible value. The rationale was that systems with memorycontrol groups (memcg) no longer need separate file descriptor limitssince memory is properly accounted. However, this change overlookedthat:1. The kernel's allocation functions still enforce INT_MAX as a maximum size regardless of memcg accounting2. Programs and tests that legitimately test file descriptor limits can inadvertently trigger massive allocations3. The resulting allocations (>8GB) are impractical and will always failsystemd's algorithm starts with INT_MAX and keeps halving the valueuntil the kernel accepts it. On most systems, this results in nr_openbeing set to 1073741816 (0x3ffffff8), which is just under 1GB of filedescriptors.While processes rarely use file descriptors near this limit in normaloperation, certain selftests (liketools/testing/selftests/core/unshare_test.c) and programs that test filedescriptor limits can trigger this issue.Fix this by adding a check in alloc_fdtable() to ensure the requestedallocation size does not exceed INT_MAX. This causes the operation tofail with -EMFILE instead of triggering a kernel warning and avoids theimpractical >8GB memory allocation request.

However, cake_enqueue still returnsNET_XMIT_SUCCESS, causing htb_enqueue to call htb_activate with anempty child qdisc. We should return NET_XMIT_CN when packets aredropped from the same tin and flow.I do not believe return value of NET_XMIT_CN is necessary for packetdrops in the case of ack filtering, as that is meant to optimizeperformance, not to signal congestion.

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. If another process allocates anmm_struct with a pgd at the same address, it may end up running into thestale entry.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: subpage: keep TOWRITE tag until folio is cleanedbtrfs_subpage_set_writeback() calls folio_start_writeback() the first timea folio is written back, and it also clears the PAGECACHE_TAG_TOWRITE tageven if there are still dirty blocks in the folio. This can break orderingguarantees, such as those required by btrfs_wait_ordered_extents().That ordering breakage leads to a real failure. For example, runninggeneric/464 on a zoned setup will hit the following ASSERT.

In zoned mode orfor compressed writes, it locks several folios for delalloc and startswriting them out. Let's call the last locked folio folio X. Suppose thewrite range only partially covers folio X, leaving some pages dirty.Process A calls btrfs_subpage_set_writeback() when building a bio. Thisfunction call clears the TOWRITE tag of folio X, whose size = 8K andthe block size = 4K. It is following state. 0 4K 8K |/////|/////| (flag: DIRTY, tag: DIRTY) <-----> Process A will write this range.Now suppose process B concurrently calls writepages() with WB_SYNC_ALL. Itcalls tag_pages_for_writeback() to tag dirty folios withPAGECACHE_TAG_TOWRITE. Since folio X is still dirty, it gets tagged. Then,B collects tagged folios using filemap_get_folios_tag() and must wait forfolio X to be written before returning from writepages(). 0 4K 8K |/////|/////| (flag: DIRTY, tag: DIRTY|TOWRITE)However, between tagging and collecting, process A may callbtrfs_subpage_set_writeback() and clear folio X's TOWRITE tag. 0 4K 8K | |/////| (flag: DIRTY|WRITEBACK, tag: DIRTY)As a result, process B won't see folio X in its batch, and returns withoutwaiting for it. This breaks the WB_SYNC_ALL ordering requirement.Fix this by using btrfs_subpage_set_writeback_keepwrite(), which retainsthe TOWRITE tag. We now manually clear the tag only after the folio becomesclean, via the xas operation.

CVE-2025-39782 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:jbd2: prevent softlockup in jbd2_log_do_checkpoint()Both jbd2_log_do_checkpoint() and jbd2_journal_shrink_checkpoint_list()periodically release j_list_lock after processing a batch of buffers toavoid long hold times on the j_list_lock. However, since both functionscontend for j_list_lock, the combined time spent waiting and processingcan be significant.jbd2_journal_shrink_checkpoint_list() explicitly calls cond_resched() whenneed_resched() is true to avoid softlockups during prolonged operations.But jbd2_log_do_checkpoint() only exits its loop when need_resched() istrue, relying on potentially sleeping functions like __flush_batch() orwait_on_buffer() to trigger rescheduling. If those functions do not sleep,the kernel may hit a softlockup.watchdog: BUG: soft lockup - CPU#3 stuck for 156s!

Description: In the Linux kernel, the following vulnerability has been resolved:bnxt_en: Fix memory corruption when FW resources change during ifdownbnxt_set_dflt_rings() assumes that it is always called before any TC hasbeen created. So it doesn't take bp->num_tc into account and assumesthat it is always 0 or 1.In the FW resource or capability change scenario, the FW will returnflags in bnxt_hwrm_if_change() that will cause the driver toreinitialize and call bnxt_cancel_reservations(). This will lead tobnxt_init_dflt_ring_mode() calling bnxt_set_dflt_rings() and bp->num_tcmay be greater than 1. This will cause bp->tx_ring[] to be sized toosmall and cause memory corruption in bnxt_alloc_cp_rings().Fix it by properly scaling the TX rings by bp->num_tc in the codepaths mentioned above.

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:io_uring/kbuf: always use READ_ONCE() to read ring provided buffer lengthsSince the buffers are mapped from userspace, it is prudent to useREAD_ONCE() to read the value into a local variable, and use that forany other actions taken. Having a stable read of the buffer lengthavoids worrying about it changing after checking, or being read multipletimes.Similarly, the buffer may well change in between it being picked andbeing committed. Ensure the looping for incremental ring buffer commitstops if it hits a zero sized buffer, as no further progress can be madeat that point.

CVE-2025-39819 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fs/smb: Fix inconsistent refcnt updateA possible inconsistent update of refcount was identified in `smb2_compound_op`.Such inconsistent update could lead to possible resource leaks.Why it is a possible bug:1. In the comment section of the function, it clearly states that thereference to `cfile` should be dropped after calling this function.2. Every control flow path would check and drop the reference to`cfile`, except the patched one.3. Existing callers would not handle refcount update of `cfile` if-ENOMEM is returned.To fix the bug, an extra goto label "out" is added, to make sure that thecleanup logic would always be respected. As the problem is caused by theallocation failure of `vars`, the cleanup logic between label "finished"and "out" can be safely ignored. According to the definition of function`is_replayable_error`, the error code of "-ENOMEM" is not recoverable.Therefore, the replay logic also gets ignored.

[0]When atmtcp_v_open() or atmtcp_v_close() is called via connect()or close(), atmtcp_send_control() is called to send an in-kernelspecial message.The message has ATMTCP_HDR_MAGIC in atmtcp_control.hdr.length.Also, a pointer of struct atm_vcc is set to atmtcp_control.vcc.The notable thing is struct atmtcp_control is uAPI but has aspace for an in-kernel pointer. struct atmtcp_control { struct atmtcp_hdr hdr; /* must be first */ ... atm_kptr_t vcc; /* both directions */ ... } __ATM_API_ALIGN; typedef struct { unsigned char _[8]; } __ATM_API_ALIGN atm_kptr_t;The special message is processed in atmtcp_recv_control() calledfrom atmtcp_c_send().atmtcp_c_send() is vcc->dev->ops->send() and called from 2 paths: 1. .ndo_start_xmit() (vcc->send() == atm_send_aal0()) 2. vcc_sendmsg()The problem is sendmsg() does not validate the message length anduserspace can abuse atmtcp_recv_control() to overwrite any kptrby atmtcp_control.Let's add a new ->pre_send() hook to validate messages from sendmsg().[0]:Oops: general protection fault, probably for non-canonical address 0xdffffc00200000ab: 0000 [#1] SMP KASAN PTIKASAN: probably user-memory-access in range [0x0000000100000558-0x000000010000055f]CPU: 0 UID: 0 PID: 5865 Comm: syz-executor331 Not tainted 6.17.0-rc1-syzkaller-00215-gbab3ce404553 #0 PREEMPT(full)Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 07/12/2025RIP: 0010:atmtcp_recv_control drivers/atm/atmtcp.c:93 [inline]RIP: 0010:atmtcp_c_send+0x1da/0x950 drivers/atm/atmtcp.c:297Code: 4d 8d 75 1a 4c 89 f0 48 c1 e8 03 42 0f b6 04 20 84 c0 0f 85 15 06 00 00 41 0f b7 1e 4d 8d b7 60 05 00 00 4c 89 f0 48 c1 e8 03 <42> 0f b6 04 20 84 c0 0f 85 13 06 00 00 66 41 89 1e 4d 8d 75 1c 4cRSP: 0018:ffffc90003f5f810 EFLAGS: 00010203RAX: 00000000200000ab RBX: 0000000000000000 RCX: 0000000000000000RDX: ffff88802a510000 RSI: 00000000ffffffff RDI: ffff888030a6068cRBP: ffff88802699fb40 R08: ffff888030a606eb R09: 1ffff1100614c0ddR10: dffffc0000000000 R11: ffffffff8718fc40 R12: dffffc0000000000R13: ffff888030a60680 R14: 000000010000055f R15: 00000000ffffffffFS: 00007f8d7e9236c0(0000) GS:ffff888125c1c000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 000000000045ad50 CR3: 0000000075bde000 CR4: 00000000003526f0Call Trace: vcc_sendmsg+0xa10/0xc60 net/atm/common.c:645 sock_sendmsg_nosec net/socket.c:714 [inline] __sock_sendmsg+0x219/0x270 net/socket.c:729 ____sys_sendmsg+0x505/0x830 net/socket.c:2614 ___sys_sendmsg+0x21f/0x2a0 net/socket.c:2668 __sys_sendmsg net/socket.c:2700 [inline] __do_sys_sendmsg net/socket.c:2705 [inline] __se_sys_sendmsg net/socket.c:2703 [inline] __x64_sys_sendmsg+0x19b/0x260 net/socket.c:2703 do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline] do_syscall_64+0xfa/0x3b0 arch/x86/entry/syscall_64.c:94 entry_SYSCALL_64_after_hwframe+0x77/0x7fRIP: 0033:0x7f8d7e96a4a9Code: 28 00 00 00 75 05 48 83 c4 28 c3 e8 51 18 00 00 90 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b0 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007f8d7e923198 EFLAGS: 00000246 ORIG_RAX: 000000000000002eRAX: ffffffffffffffda RBX: 00007f8d7e9f4308 RCX: 00007f8d7e96a4a9RDX: 0000000000000000 RSI: 0000200000000240 RDI: 0000000000000005RBP: 00007f8d7e9f4300 R08: 65732f636f72702f R09: 65732f636f72702fR10: 65732f636f72702f R11: 0000000000000246 R12: 00007f8d7e9c10acR13: 00007f8d7e9231a0 R14: 0000200000000200 R15: 0000200000000250 Modules linked in:

We should be enabling this sooner as a part of thendo_open path and then just letting the service task come online later.This will help to enforce the correct locking and brings the phylinkinterface online at the same time as the network interface, instead of at alater time.I tested this on QEMU to verify this was working by putting the system tosleep using "echo mem > /sys/power/state" to put the system to sleep in theguest and then using the command "system_wakeup" in the QEMU monitor.

CVE-2025-39835 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:xfs: do not propagate ENODATA disk errors into xattr codeENODATA (aka ENOATTR) has a very specific meaning in the xfs xattr code;namely, that the requested attribute name could not be found.However, a medium error from disk may also return ENODATA. At best,this medium error may escape to userspace as "attribute not found"when in fact it's an IO (disk) error.At worst, we may oops in xfs_attr_leaf_get() when we do: error = xfs_attr_leaf_hasname(args, &bp); if (error == -ENOATTR) { xfs_trans_brelse(args->trans, bp); return error; }because an ENODATA/ENOATTR error from disk leaves us with a null bp,and the xfs_trans_brelse will then null-deref it.As discussed on the list, we really need to modify the lower levelIO functions to trap all disk errors and ensure that we don't letunique errors like this leak up into higher xfs functions - manylike this should be remapped to EIO.However, this patch directly addresses a reported bug in the xattrcode, and should be safe to backport to stable kernels. A larger-scopepatch to handle more unique errors at lower levels can follow later.(Note, prior to 07120f1abdff we did not oops, but we did return thewrong error code to userspace.)

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: lpfc: Fix buffer free/clear order in deferred receive pathFix a use-after-free window by correcting the buffer release sequence inthe deferred receive path. The code freed the RQ buffer first and onlythen cleared the context pointer under the lock. Concurrent paths (e.g.,ABTS and the repost path) also inspect and release the same pointer underthe lock, so the old order could lead to double-free/UAF.Note that the repost path already uses the correct pattern: detach thepointer under the lock, then free it after dropping the lock. Thedeferred path should do the same.

Description: In the Linux kernel, the following vulnerability has been resolved:mm: slub: avoid wake up kswapd in set_track_prepareset_track_prepare() can incur lock recursion.The issue is that it is called from hrtimer_start_range_nsholding the per_cpu(hrtimer_bases)[n].lock, but when enabledCONFIG_DEBUG_OBJECTS_TIMERS, may wake up kswapd in set_track_prepare,and try to hold the per_cpu(hrtimer_bases)[n].lock.Avoid deadlock caused by implicitly waking up kswapd by passing inallocation flags, which do not contain __GFP_KSWAPD_RECLAIM in thedebug_objects_fill_pool() case. Inside stack depot they are processed bygfp_nested_mask().Since ___slab_alloc() has preemption disabled, we mask out__GFP_DIRECT_RECLAIM from the flags there.The oops looks something like:BUG: spinlock recursion on CPU#3, swapper/3/0 lock: 0xffffff8a4bf29c80, .magic: dead4ead, .owner: swapper/3/0, .owner_cpu: 3Hardware name: Qualcomm Technologies, Inc.

CVE-2025-39844 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm: move page table sync declarations to linux/pgtable.hDuring our internal testing, we started observing intermittent bootfailures when the machine uses 4-level paging and has a large amount ofpersistent memory: BUG: unable to handle page fault for address: ffffe70000000034 #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page PGD 0 P4D 0 Oops: 0002 [#1] SMP NOPTI RIP: 0010:__init_single_page+0x9/0x6d Call Trace: __init_zone_device_page+0x17/0x5d memmap_init_zone_device+0x154/0x1bb pagemap_range+0x2e0/0x40f memremap_pages+0x10b/0x2f0 devm_memremap_pages+0x1e/0x60 dev_dax_probe+0xce/0x2ec [device_dax] dax_bus_probe+0x6d/0xc9 [... snip ...] It turns out that the kernel panics while initializing vmemmap (structpage array) when the vmemmap region spans two PGD entries, because the newPGD entry is only installed in init_mm.pgd, but not in the page tables ofother tasks.And looking at __populate_section_memmap(): if (vmemmap_can_optimize(altmap, pgmap)) // does not sync top level page tables r = vmemmap_populate_compound_pages(pfn, start, end, nid, pgmap); else // sync top level page tables in x86 r = vmemmap_populate(start, end, nid, altmap);In the normal path, vmemmap_populate() in arch/x86/mm/init_64.csynchronizes the top level page table (See commit 9b861528a801 ("x86-64,mem: Update all PGDs for direct mapping and vmemmap mapping changes")) sothat all tasks in the system can see the new vmemmap area.However, when vmemmap_can_optimize() returns true, the optimized pathskips synchronization of top-level page tables. This is becausevmemmap_populate_compound_pages() is implemented in core MM code, whichdoes not handle synchronization of the top-level page tables. Instead,the core MM has historically relied on each architecture to perform thissynchronization manually.We're not the first party to encounter a crash caused by not-sync'd toplevel page tables: earlier this year, Gwan-gyeong Mun attempted to addressthe issue [1] [2] after hitting a kernel panic when x86 code accessed thevmemmap area before the corresponding top-level entries were synced. Atthat time, the issue was believed to be triggered only when struct pagewas enlarged for debugging purposes, and the patch did not get furtherupdates.It turns out that current approach of relying on each arch to handle thepage table sync manually is fragile because 1) it's easy to forget to syncthe top level page table, and 2) it's also easy to overlook that thekernel should not access the vmemmap and direct mapping areas before thesync.# The solution: Make page table sync more code robust and harder to missTo address this, Dave Hansen suggested [3] [4] introducing{pgd,p4d}_populate_kernel() for updating kernel portion of the page tablesand allow each architecture to explicitly perform synchronization wheninstalling top-level entries. With this approach, we no longer need toworry about missing the sync step, reducing the risk of futureregressions.The new interface reuses existing ARCH_PAGE_TABLE_SYNC_MASK,PGTBL_P*D_MODIFIED and arch_sync_kernel_mappings() facility used byvmalloc and ioremap to synchronize page tables.pgd_populate_kernel() looks like this:static inline void pgd_populate_kernel(unsigned long addr, pgd_t *pgd, p4d_t *p4d){ pgd_populate(&init_mm, pgd, p4d); if (ARCH_PAGE_TABLE_SYNC_MASK & PGTBL_PGD_MODIFIED) arch_sync_kernel_mappings(addr, addr);}It is worth noting that vmalloc() and apply_to_range() carefullysynchronizes page tables by calling p*d_alloc_track() andarch_sync_kernel_mappings(), and thus they are not affected by---truncated---

CVE-2025-39847 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ppp: fix memory leak in pad_compress_skbIf alloc_skb() fails in pad_compress_skb(), it returns NULL withoutreleasing the old skb. The caller does: skb = pad_compress_skb(ppp, skb); if (!skb) goto drop;drop: kfree_skb(skb);When pad_compress_skb() returns NULL, the reference to the old skb islost and kfree_skb(skb) ends up doing nothing, leading to a memory leak.Align pad_compress_skb() semantics with realloc(): only free the oldskb if allocation and compression succeed. At the call site, use thenew_skb variable so the original skb is not lost when pad_compress_skb()fails.

CVE-2025-39863 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: brcmfmac: fix use-after-free when rescheduling brcmf_btcoex_info workThe brcmf_btcoex_detach() only shuts down the btcoex timer, if theflag timer_on is false. However, the brcmf_btcoex_timerfunc(), whichruns as timer handler, sets timer_on to false. This creates criticalrace conditions:1.If brcmf_btcoex_detach() is called while brcmf_btcoex_timerfunc()is executing, it may observe timer_on as false and skip the call totimer_shutdown_sync().2.The brcmf_btcoex_timerfunc() may then reschedule the brcmf_btcoex_infoworker after the cancel_work_sync() has been executed, resulting inuse-after-free bugs.The use-after-free bugs occur in two distinct scenarios, depending onthe timing of when the brcmf_btcoex_info struct is freed relative tothe execution of its worker thread.Scenario 1: Freed before the worker is scheduledThe brcmf_btcoex_info is deallocated before the worker is scheduled.A race condition can occur when schedule_work(&bt_local->work) iscalled after the target memory has been freed. The sequence of eventsis detailed below:CPU0 | CPU1brcmf_btcoex_detach | brcmf_btcoex_timerfunc | bt_local->timer_on = false; if (cfg->btcoex->timer_on) | ... | cancel_work_sync(); | ... | kfree(cfg->btcoex); // FREE | | schedule_work(&bt_local->work); // USEScenario 2: Freed after the worker is scheduledThe brcmf_btcoex_info is freed after the worker has been scheduledbut before or during its execution. In this case, statements withinthe brcmf_btcoex_handler() - such as the container_of macro andsubsequent dereferences of the brcmf_btcoex_info object will causea use-after-free access. The following timeline illustrates thisscenario:CPU0 | CPU1brcmf_btcoex_detach | brcmf_btcoex_timerfunc | bt_local->timer_on = false; if (cfg->btcoex->timer_on) | ... | cancel_work_sync(); | ... | schedule_work(); // Reschedule | kfree(cfg->btcoex); // FREE | brcmf_btcoex_handler() // Worker /* | btci = container_of(....); // USE The kfree() above could | ... also occur at any point | btci-> // USE during the worker's execution| */ |To resolve the race conditions, drop the conditional check and calltimer_shutdown_sync() directly. It can deactivate the timer reliably,regardless of its current state. Once stopped, the timer_on state isthen set to false.

Description: In the Linux kernel, the following vulnerability has been resolved:can: xilinx_can: xcan_write_frame(): fix use-after-free of transmitted SKBcan_put_echo_skb() takes ownership of the SKB and it may be freedduring or after the call.However, xilinx_can xcan_write_frame() keeps using SKB after the call.Fix that by only calling can_put_echo_skb() after the code is donetouching the SKB.The tx_lock is held for the entire xcan_write_frame() execution andalso on the can_get_echo_skb() side so the order of operations does notmatter.An earlier fix commit 3d3c817c3a40 ("can: xilinx_can: Fix usage of skbmemory") did not move the can_put_echo_skb() call far enough.[mkl: add "commit" in front of sha1 in patch description][mkl: fix indention]

CVE-2025-39880 Severity: Moderate CVSS3 score: 5.5

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.

CVE-2025-39884 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix subvolume deletion lockup caused by inodes xarray raceThere is a race condition between inode eviction and inode caching thatcan cause a live struct btrfs_inode to be missing from the root->inodesxarray. Specifically, there is a window during evict() between the inodebeing unhashed and deleted from the xarray. If btrfs_iget() is calledfor the same inode in that window, it will be recreated and insertedinto the xarray, but then eviction will delete the new entry, leavingnothing in the xarray:Thread 1 Thread 2---------------------------------------------------------------evict() remove_inode_hash() btrfs_iget_path() btrfs_iget_locked() btrfs_read_locked_inode() btrfs_add_inode_to_root() destroy_inode() btrfs_destroy_inode() btrfs_del_inode_from_root() __xa_eraseIn turn, this can cause issues for subvolume deletion. Specifically, ifan inode is in this lost state, and all other inodes are evicted, thenbtrfs_del_inode_from_root() will call btrfs_add_dead_root() prematurely.If the lost inode has a delayed_node attached to it, then whenbtrfs_clean_one_deleted_snapshot() calls btrfs_kill_all_delayed_nodes(),it will loop forever because the delayed_nodes xarray will never becomeempty (unless memory pressure forces the inode out). We saw thismanifest as soft lockups in production.Fix it by only deleting the xarray entry if it matches the given inode(using __xa_cmpxchg()).

CVE-2025-39902 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm/slub: avoid accessing metadata when pointer is invalid in object_err()object_err() reports details of an object for further debugging, such asthe freelist pointer, redzone, etc. However, if the pointer is invalid,attempting to access object metadata can lead to a crash since it doesnot point to a valid object.One known path to the crash is when alloc_consistency_checks()determines the pointer to the allocated object is invalid because of afreelist corruption, and calls object_err() to report it. The debug codeshould report and handle the corruption gracefully and not crash in theprocess.In case the pointer is NULL or check_valid_pointer() returns false forthe pointer, only print the pointer value and skip accessing metadata.

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

Description: In the Linux kernel, the following vulnerability has been resolved:tcp_bpf: Call sk_msg_free() when tcp_bpf_send_verdict() fails to allocate psock->cork.syzbot reported the splat below. [0]The repro does the following: 1. Load a sk_msg prog that calls bpf_msg_cork_bytes(msg, cork_bytes) 2. Attach the prog to a SOCKMAP 3. Add a socket to the SOCKMAP 4. Activate fault injection 5. Send data less than cork_bytesAt 5., the data is carried over to the next sendmsg() as it issmaller than the cork_bytes specified by bpf_msg_cork_bytes().Then, tcp_bpf_send_verdict() tries to allocate psock->cork to holdthe data, but this fails silently due to fault injection + __GFP_NOWARN.If the allocation fails, we need to revert the sk->sk_forward_allocchange done by sk_msg_alloc().Let's call sk_msg_free() when tcp_bpf_send_verdict fails to allocatepsock->cork.The "*copied" also needs to be updated such that a proper error canbe returned to the caller, sendmsg. It fails to allocate psock->cork.Nothing has been corked so far, so this patch simply sets "*copied"to 0.[0]:WARNING: net/ipv4/af_inet.c:156 at inet_sock_destruct+0x623/0x730 net/ipv4/af_inet.c:156, CPU#1: syz-executor/5983Modules linked in:CPU: 1 UID: 0 PID: 5983 Comm: syz-executor Not tainted syzkaller #0 PREEMPT(full)Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 07/12/2025RIP: 0010:inet_sock_destruct+0x623/0x730 net/ipv4/af_inet.c:156Code: 0f 0b 90 e9 62 fe ff ff e8 7a db b5 f7 90 0f 0b 90 e9 95 fe ff ff e8 6c db b5 f7 90 0f 0b 90 e9 bb fe ff ff e8 5e db b5 f7 90 <0f> 0b 90 e9 e1 fe ff ff 89 f9 80 e1 07 80 c1 03 38 c1 0f 8c 9f fcRSP: 0018:ffffc90000a08b48 EFLAGS: 00010246RAX: ffffffff8a09d0b2 RBX: dffffc0000000000 RCX: ffff888024a23c80RDX: 0000000000000100 RSI: 0000000000000fff RDI: 0000000000000000RBP: 0000000000000fff R08: ffff88807e07c627 R09: 1ffff1100fc0f8c4R10: dffffc0000000000 R11: ffffed100fc0f8c5 R12: ffff88807e07c380R13: dffffc0000000000 R14: ffff88807e07c60c R15: 1ffff1100fc0f872FS: 00005555604c4500(0000) GS:ffff888125af1000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00005555604df5c8 CR3: 0000000032b06000 CR4: 00000000003526f0Call Trace: __sk_destruct+0x86/0x660 net/core/sock.c:2339 rcu_do_batch kernel/rcu/tree.c:2605 [inline] rcu_core+0xca8/0x1770 kernel/rcu/tree.c:2861 handle_softirqs+0x286/0x870 kernel/softirq.c:579 __do_softirq kernel/softirq.c:613 [inline] invoke_softirq kernel/softirq.c:453 [inline] __irq_exit_rcu+0xca/0x1f0 kernel/softirq.c:680 irq_exit_rcu+0x9/0x30 kernel/softirq.c:696 instr_sysvec_apic_timer_interrupt arch/x86/kernel/apic/apic.c:1052 [inline] sysvec_apic_timer_interrupt+0xa6/0xc0 arch/x86/kernel/apic/apic.c:1052

Description: In the Linux kernel, the following vulnerability has been resolved:can: j1939: implement NETDEV_UNREGISTER notification handlersyzbot is reporting unregister_netdevice: waiting for vcan0 to become free. Usage count = 2problem, for j1939 protocol did not have NETDEV_UNREGISTER notificationhandler for undoing changes made by j1939_sk_bind().Commit 25fe97cb7620 ("can: j1939: move j1939_priv_put() into sk_destructcallback") expects that a call to j1939_priv_put() can be unconditionallydelayed until j1939_sk_sock_destruct() is called. But we need to callj1939_priv_put() against an extra ref held by j1939_sk_bind() call(as a part of undoing changes made by j1939_sk_bind()) as soon asNETDEV_UNREGISTER notification fires (i.e. before j1939_sk_sock_destruct()is called via j1939_sk_release()). Otherwise, the extra ref on "structj1939_priv" held by j1939_sk_bind() call prevents "struct net_device" fromdropping the usage count to 1; making it impossible forunregister_netdevice() to continue.[mkl: remove space in front of label]

This leads to memory corruption when we copy datait on the next line: memcpy(sma1307->set.header, data, sma1307->set.header_size * sizeof(int));Also since we're immediately copying over the memory in ->set.header,there is no need to zero it in the allocator.

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

CVE-2025-39944 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:octeontx2-pf: Fix use-after-free bugs in otx2_sync_tstamp()The original code relies on cancel_delayed_work() in otx2_ptp_destroy(),which does not ensure that the delayed work item synctstamp_work has fullycompleted if it was already running. This leads to use-after-free scenarioswhere otx2_ptp is deallocated by otx2_ptp_destroy(), while synctstamp_workremains active and attempts to dereference otx2_ptp in otx2_sync_tstamp().Furthermore, the synctstamp_work is cyclic, the likelihood of triggeringthe bug is nonnegligible.A typical race condition is illustrated below:CPU 0 (cleanup) | CPU 1 (delayed work callback)otx2_remove() | otx2_ptp_destroy() | otx2_sync_tstamp() cancel_delayed_work() | kfree(ptp) | | ptp = container_of(...); //UAF | ptp-> //UAFThis is confirmed by a KASAN report:BUG: KASAN: slab-use-after-free in __run_timer_base.part.0+0x7d7/0x8c0Write of size 8 at addr ffff88800aa09a18 by task bash/136...Call Trace: dump_stack_lvl+0x55/0x70 print_report+0xcf/0x610 ? __run_timer_base.part.0+0x7d7/0x8c0 kasan_report+0xb8/0xf0 ? __run_timer_base.part.0+0x7d7/0x8c0 __run_timer_base.part.0+0x7d7/0x8c0 ? __pfx___run_timer_base.part.0+0x10/0x10 ? __pfx_read_tsc+0x10/0x10 ? ktime_get+0x60/0x140 ? lapic_next_event+0x11/0x20 ? clockevents_program_event+0x1d4/0x2a0 run_timer_softirq+0xd1/0x190 handle_softirqs+0x16a/0x550 irq_exit_rcu+0xaf/0xe0 sysvec_apic_timer_interrupt+0x70/0x80 ...Allocated by task 1: kasan_save_stack+0x24/0x50 kasan_save_track+0x14/0x30 __kasan_kmalloc+0x7f/0x90 otx2_ptp_init+0xb1/0x860 otx2_probe+0x4eb/0xc30 local_pci_probe+0xdc/0x190 pci_device_probe+0x2fe/0x470 really_probe+0x1ca/0x5c0 __driver_probe_device+0x248/0x310 driver_probe_device+0x44/0x120 __driver_attach+0xd2/0x310 bus_for_each_dev+0xed/0x170 bus_add_driver+0x208/0x500 driver_register+0x132/0x460 do_one_initcall+0x89/0x300 kernel_init_freeable+0x40d/0x720 kernel_init+0x1a/0x150 ret_from_fork+0x10c/0x1a0 ret_from_fork_asm+0x1a/0x30Freed by task 136: kasan_save_stack+0x24/0x50 kasan_save_track+0x14/0x30 kasan_save_free_info+0x3a/0x60 __kasan_slab_free+0x3f/0x50 kfree+0x137/0x370 otx2_ptp_destroy+0x38/0x80 otx2_remove+0x10d/0x4c0 pci_device_remove+0xa6/0x1d0 device_release_driver_internal+0xf8/0x210 pci_stop_bus_device+0x105/0x150 pci_stop_and_remove_bus_device_locked+0x15/0x30 remove_store+0xcc/0xe0 kernfs_fop_write_iter+0x2c3/0x440 vfs_write+0x871/0xd70 ksys_write+0xee/0x1c0 do_syscall_64+0xac/0x280 entry_SYSCALL_64_after_hwframe+0x77/0x7f...Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensurethat the delayed work item is properly canceled before the otx2_ptp isdeallocated.This bug was initially identified through static analysis.

CVE-2025-39946 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:tls: make sure to abort the stream if headers are bogusNormally we wait for the socket to buffer up the whole recordbefore we service it. If the socket has a tiny buffer, however,we read out the data sooner, to prevent connection stalls.Make sure that we abort the connection when we find out latethat the record is actually invalid. Retrying the parsing isfine in itself but since we copy some more data each timebefore we parse we can overflow the allocated skb space.Constructing a scenario in which we're under pressure withoutenough data in the socket to parse the length upfront is quitehard. syzbot figured out a way to do this by serving us the headerin small OOB sends, and then filling in the recvbuf with a largenormal send.Make sure that tls_rx_msg_size() aborts strp, if we reachan invalid record there's really no way to recover.

CVE-2025-39989 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:x86/mce: use is_copy_from_user() to determine copy-from-user contextPatch series "mm/hwpoison: Fix regressions in memory failure handling",v4.## 1. What am I trying to do:This patchset resolves two critical regressions related to memory failurehandling that have appeared in the upstream kernel since version 5.17, ascompared to 5.10 LTS. - copyin case: poison found in user page while kernel copying from user space - instr case: poison found while instruction fetching in user space## 2. What is the expected outcome and why- For copyin case:Kernel can recover from poison found where kernel is doing get_user() orcopy_from_user() if those places get an error return and the kernel return-EFAULT to the process instead of crashing. More specifily, MCE handlerchecks the fixup handler type to decide whether an in kernel #MC can berecovered. When EX_TYPE_UACCESS is found, the PC jumps to recovery codespecified in _ASM_EXTABLE_FAULT() and return a -EFAULT to user space.- For instr case:If a poison found while instruction fetching in user space, full recoveryis possible. User process takes #PF, Linux allocates a new page and fillsby reading from storage.## 3. What actually happens and why- For copyin case: kernel panic since v5.17Commit 4c132d1d844a ("x86/futex: Remove .fixup usage") introduced a newextable fixup type, EX_TYPE_EFAULT_REG, and later patches updated theextable fixup type for copy-from-user operations, changing it fromEX_TYPE_UACCESS to EX_TYPE_EFAULT_REG. It breaks previous EX_TYPE_UACCESShandling when posion found in get_user() or copy_from_user().- For instr case: user process is killed by a SIGBUS signal due to #CMCI and #MCE raceWhen an uncorrected memory error is consumed there is a race between theCMCI from the memory controller reporting an uncorrected error with a UCNAsignature, and the core reporting and SRAR signature machine check whenthe data is about to be consumed.### Background: why *UN*corrected errors tied to *C*MCI in Intel platform [1]Prior to Icelake memory controllers reported patrol scrub events thatdetected a previously unseen uncorrected error in memory by signaling abroadcast machine check with an SRAO (Software Recoverable ActionOptional) signature in the machine check bank. This was overkill becauseit's not an urgent problem that no core is on the verge of consuming thatbad data. It's also found that multi SRAO UCE may cause nested MCEinterrupts and finally become an IERR.Hence, Intel downgrades the machine check bank signature of patrol scrubfrom SRAO to UCNA (Uncorrected, No Action required), and signal changed to#CMCI. Just to add to the confusion, Linux does take an action (inuc_decode_notifier()) to try to offline the page despite the UC*NA*signature name.### Background: why #CMCI and #MCE race when poison is consuming in Intel platform [1]Having decided that CMCI/UCNA is the best action for patrol scrub errors,the memory controller uses it for reads too. But the memory controller isexecuting asynchronously from the core, and can't tell the differencebetween a "real" read and a speculative read. So it will do CMCI/UCNA ifan error is found in any read.Thus:1) Core is clever and thinks address A is needed soon, issues a speculative read.2) Core finds it is going to use address A soon after sending the read request3) The CMCI from the memory controller is in a race with MCE from the core that will soon try to retire the load from address A.Quite often (because speculation has got better) the CMCI from the memorycontroller is delivered before the core is committed to the instructionreading address A, so the interrupt is taken, and Linux offlines the page(marking it as poison).## Why user process is killed for instr caseCommit 046545a661af ("mm/hwpoison: fix error page recovered but reported"not---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:mm: swap: check for stable address space before operating on the VMAIt is possible to hit a zero entry while traversing the vmas in unuse_mm()called from swapoff path and accessing it causes the OOPS:Unable to handle kernel NULL pointer dereference at virtual address0000000000000446--> Loading the memory from offset 0x40 on theXA_ZERO_ENTRY as address.Mem abort info: ESR = 0x0000000096000005 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x05: level 1 translation faultThe issue is manifested from the below race between the fork() on aprocess and swapoff:fork(dup_mmap()) swapoff(unuse_mm)--------------- -----------------1) Identical mtree is built using __mt_dup().2) copy_pte_range()--> copy_nonpresent_pte(): The dst mm is added into the mmlist to be visible to the swapoff operation.3) Fatal signal is sent to the parentprocess(which is the current during thefork) thus skip the duplication of thevmas and mark the vma range withXA_ZERO_ENTRY as a marker for this processthat helps during exit_mmap(). 4) swapoff is tried on the 'mm' added to the 'mmlist' as part of the 2. 5) unuse_mm(), that iterates through the vma's of this 'mm' will hit the non-NULL zero entry and operating on this zero entry as a vma is resulting into the oops.The proper fix would be around not exposing this partially-valid tree toothers when droping the mmap lock, which is being solved with [1]. Asimpler solution would be checking for MMF_UNSTABLE, as it is set ifmm_struct is not fully initialized in dup_mmap().Thanks to Liam/Lorenzo/David for all the suggestions in fixing thisissue.

CVE-2025-40052 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: fix crypto buffers in non-linear memoryThe crypto API, through the scatterlist API, expects input buffers to bein linear memory. We handle this with the cifs_sg_set_buf() helperthat converts vmalloc'd memory to their corresponding pages.However, when we allocate our aead_request buffer (@creq insmb2ops.c::crypt_message()), we do so with kvzalloc(), which possiblyputs aead_request->__ctx in vmalloc area.AEAD algorithm then uses ->__ctx for its private/internal data andoperations, and uses sg_set_buf() for such data on a few places.This works fine as long as @creq falls into kmalloc zone (smallrequests) or vmalloc'd memory is still within linear range.Tasks' stacks are vmalloc'd by default (CONFIG_VMAP_STACK=y), so toomany tasks will increment the base stacks' addresses to a point wherevirt_addr_valid(buf) will fail (BUG() in sg_set_buf()) when thathappens.In practice: too many parallel reads and writes on an encrypted mountwill trigger this bug.To fix this, always alloc @creq with kmalloc() instead.Also drop the @sensitive_size variable/arguments sincekfree_sensitive() doesn't need it.Backtrace:[ 945.272081] ------------[ cut here ]------------[ 945.272774] kernel BUG at include/linux/scatterlist.h:209![ 945.273520] Oops: invalid opcode: 0000 [#1] SMP DEBUG_PAGEALLOC NOPTI[ 945.274412] CPU: 7 UID: 0 PID: 56 Comm: kworker/u33:0 Kdump: loaded Not tainted 6.15.0-lku-11779-g8e9d6efccdd7-dirty #1 PREEMPT(voluntary)[ 945.275736] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.16.3-2-gc13ff2cd-prebuilt.qemu.org 04/01/2014[ 945.276877] Workqueue: writeback wb_workfn (flush-cifs-2)[ 945.277457] RIP: 0010:crypto_gcm_init_common+0x1f9/0x220[ 945.278018] Code: b0 00 00 00 48 83 c4 08 5b 5d 41 5c 41 5d 41 5e 41 5f c3 cc cc cc cc 48 c7 c0 00 00 00 80 48 2b 05 5c 58 e5 00 e9 58 ff ff ff <0f> 0b 0f 0b 0f 0b 0f 0b 0f 0b 0f 0b 48 c7 04 24 01 00 00 00 48 8b[ 945.279992] RSP: 0018:ffffc90000a27360 EFLAGS: 00010246[ 945.280578] RAX: 0000000000000000 RBX: ffffc90001d85060 RCX: 0000000000000030[ 945.281376] RDX: 0000000000080000 RSI: 0000000000000000 RDI: ffffc90081d85070[ 945.282145] RBP: ffffc90001d85010 R08: ffffc90001d85000 R09: 0000000000000000[ 945.282898] R10: ffffc90001d85090 R11: 0000000000001000 R12: ffffc90001d85070[ 945.283656] R13: ffff888113522948 R14: ffffc90001d85060 R15: ffffc90001d85010[ 945.284407] FS: 0000000000000000(0000) GS:ffff8882e66cf000(0000) knlGS:0000000000000000[ 945.285262] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 945.285884] CR2: 00007fa7ffdd31f4 CR3: 000000010540d000 CR4: 0000000000350ef0[ 945.286683] Call Trace:[ 945.286952] [ 945.287184] ? crypt_message+0x33f/0xad0 [cifs][ 945.287719] crypto_gcm_encrypt+0x36/0xe0[ 945.288152] crypt_message+0x54a/0xad0 [cifs][ 945.288724] smb3_init_transform_rq+0x277/0x300 [cifs][ 945.289300] smb_send_rqst+0xa3/0x160 [cifs][ 945.289944] cifs_call_async+0x178/0x340 [cifs][ 945.290514] ? __pfx_smb2_writev_callback+0x10/0x10 [cifs][ 945.291177] smb2_async_writev+0x3e3/0x670 [cifs][ 945.291759] ? find_held_lock+0x32/0x90[ 945.292212] ? netfs_advance_write+0xf2/0x310[ 945.292723] netfs_advance_write+0xf2/0x310[ 945.293210] netfs_write_folio+0x346/0xcc0[ 945.293689] ? __pfx__raw_spin_unlock_irq+0x10/0x10[ 945.294250] netfs_writepages+0x117/0x460[ 945.294724] do_writepages+0xbe/0x170[ 945.295152] ? find_held_lock+0x32/0x90[ 945.295600] ? kvm_sched_clock_read+0x11/0x20[ 945.296103] __writeback_single_inode+0x56/0x4b0[ 945.296643] writeback_sb_inodes+0x229/0x550[ 945.297140] __writeback_inodes_wb+0x4c/0xe0[ 945.297642] wb_writeback+0x2f1/0x3f0[ 945.298069] wb_workfn+0x300/0x490[ 945.298472] process_one_work+0x1fe/0x590[ 945.298949] worker_thread+0x1ce/0x3c0[ 945.299397] ? __pfx_worker_thread+0x10/0x10[ 945.299900] kthr---truncated---

CVE-2025-40058 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:iommu/vt-d: Disallow dirty tracking if incoherent page walkDirty page tracking relies on the IOMMU atomically updating the dirty bitin the paging-structure entry. For this operation to succeed, the paging-structure memory must be coherent between the IOMMU and the CPU. Inanother word, if the iommu page walk is incoherent, dirty page trackingdoesn't work.The Intel VT-d specification, Section 3.10 "Snoop Behavior" states:"Remapping hardware encountering the need to atomically update A/EA/D bits in a paging-structure entry that is not snooped will result in a non- recoverable fault."To prevent an IOMMU from being incorrectly configured for dirty pagetracking when it is operating in an incoherent mode, mark SSADS assupported only when both ecap_slads and ecap_smpwc are supported.

CVE-2025-40060 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:coresight: trbe: Return NULL pointer for allocation failuresWhen the TRBE driver fails to allocate a buffer, it currently returnsthe error code "-ENOMEM". However, the caller etm_setup_aux() onlychecks for a NULL pointer, so it misses the error. As a result, thedriver continues and eventually causes a kernel panic.Fix this by returning a NULL pointer from arm_trbe_alloc_buffer() onallocation failures. This allows that the callers can properly handlethe failure.

CVE-2025-40061 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/rxe: Fix race in do_task() when drainingWhen do_task() exhausts its iteration budget (!ret), it sets the stateto TASK_STATE_IDLE to reschedule, without a secondary check on thecurrent task->state. This can overwrite the TASK_STATE_DRAINING stateset by a concurrent call to rxe_cleanup_task() or rxe_disable_task().While state changes are protected by a spinlock, both rxe_cleanup_task()and rxe_disable_task() release the lock while waiting for the task tofinish draining in the while(!is_done(task)) loop. The race occurs ifdo_task() hits its iteration limit and acquires the lock in this window.The cleanup logic may then proceed while the task incorrectlyreschedules itself, leading to a potential use-after-free.This bug was introduced during the migration from tasklets to workqueues,where the special handling for the draining case was lost.Fix this by restoring the original pre-migration behavior. If the state isTASK_STATE_DRAINING when iterations are exhausted, set cont to 1 toforce a new loop iteration. This allows the task to finish its work, sothat a subsequent iteration can reach the switch statement and correctlytransition the state to TASK_STATE_DRAINED, stopping the task as intended.

Then, UAF happenedat __pnet_find_base_ndev() when the dev is first used.This means dev had already been freed before acquiring RTNL inpnet_find_base_ndev().While dev is going away, dst->dev could be swapped with blackhole_netdev,and the dev's refcnt by dst will be released.We must hold dev's refcnt before calling smc_pnet_find_ism_resource().Also, smc_pnet_find_roce_resource() has the same problem.Let's use __sk_dst_get() and dst_dev_rcu() in the two functions.[0]:BUG: KASAN: use-after-free in __pnet_find_base_ndev+0x1b1/0x1c0 net/smc/smc_pnet.c:926Read of size 1 at addr ffff888036bac33a by task syz.0.3632/18609CPU: 1 UID: 0 PID: 18609 Comm: syz.0.3632 Not tainted syzkaller #0 PREEMPT(full)Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 08/18/2025Call Trace: dump_stack_lvl+0x189/0x250 lib/dump_stack.c:120 print_address_description mm/kasan/report.c:378 [inline] print_report+0xca/0x240 mm/kasan/report.c:482 kasan_report+0x118/0x150 mm/kasan/report.c:595 __pnet_find_base_ndev+0x1b1/0x1c0 net/smc/smc_pnet.c:926 pnet_find_base_ndev net/smc/smc_pnet.c:946 [inline] smc_pnet_find_ism_by_pnetid net/smc/smc_pnet.c:1103 [inline] smc_pnet_find_ism_resource+0xef/0x390 net/smc/smc_pnet.c:1154 smc_find_ism_device net/smc/af_smc.c:1030 [inline] smc_find_proposal_devices net/smc/af_smc.c:1115 [inline] __smc_connect+0x372/0x1890 net/smc/af_smc.c:1545 smc_connect+0x877/0xd90 net/smc/af_smc.c:1715 __sys_connect_file net/socket.c:2086 [inline] __sys_connect+0x313/0x440 net/socket.c:2105 __do_sys_connect net/socket.c:2111 [inline] __se_sys_connect net/socket.c:2108 [inline] __x64_sys_connect+0x7a/0x90 net/socket.c:2108 do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline] do_syscall_64+0xfa/0x3b0 arch/x86/entry/syscall_64.c:94 entry_SYSCALL_64_after_hwframe+0x77/0x7fRIP: 0033:0x7f47cbf8eba9Code: ff ff c3 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 a8 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007f47ccdb1038 EFLAGS: 00000246 ORIG_RAX: 000000000000002aRAX: ffffffffffffffda RBX: 00007f47cc1d5fa0 RCX: 00007f47cbf8eba9RDX: 0000000000000010 RSI: 0000200000000280 RDI: 000000000000000bRBP: 00007f47cc011e19 R08: 0000000000000000 R09: 0000000000000000R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000R13: 00007f47cc1d6038 R14: 00007f47cc1d5fa0 R15: 00007ffc512f8aa8 The buggy address belongs to the physical page:page: refcount:0 mapcount:0 mapping:0000000000000000 index:0xffff888036bacd00 pfn:0x36bacflags: 0xfff00000000000(node=0|zone=1|lastcpupid=0x7ff)raw: 00fff00000000000 ffffea0001243d08 ffff8880b863fdc0 0000000000000000raw: ffff888036bacd00 0000000000000000 00000000ffffffff 0000000000000000page dumped because: kasan: bad access detectedpage_owner tracks the page as freedpage last allocated via order 2, migratetype Unmovable, gfp_mask 0x446dc0(GFP_KERNEL_ACCOUNT|__GFP_ZERO|__GFP_NOWARN|__GFP_RETRY_MAYFAIL|__GFP_COMP), pid 16741, tgid 16741 (syz-executor), ts 343313197788, free_ts 380670750466 set_page_owner include/linux/page_owner.h:32 [inline] post_alloc_hook+0x240/0x2a0 mm/page_alloc.c:1851 prep_new_page mm/page_alloc.c:1859 [inline] get_page_from_freelist+0x21e4/0x22c0 mm/page_alloc.c:3858 __alloc_frozen_pages_noprof+0x181/0x370 mm/page_alloc.c:5148 alloc_pages_mpol+0x232/0x4a0 mm/mempolicy.c:2416 ___kmalloc_large_node+0x5f/0x1b0 mm/slub.c:4317 __kmalloc_large_node_noprof+0x18/0x90 mm/slub.c:4348 __do_kmalloc_node mm/slub.c:4364 [inline] __kvmalloc_node---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:tty: n_gsm: Don't block input queue by waiting MSCCurrently gsm_queue() processes incoming frames and when openinga DLC channel it calls gsm_dlci_open() which calls gsm_modem_update().If basic mode is used it calls gsm_modem_upd_via_msc() and itcannot block the input queue by waiting the response to comeinto the same input queue.Instead allow sending Modem Status Command without waiting for remoteend to respond. Define a new function gsm_modem_send_initial_msc()for this purpose. As MSC is only valid for basic encoding, it doesnot do anything for advanced or when convergence layer type 2 is used.

CVE-2025-40078 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Explicitly check accesses to bpf_sock_addrSyzkaller found a kernel warning on the following sock_addr program: 0: r0 = 0 1: r2 = *(u32 *)(r1 +60) 2: exitwhich triggers: verifier bug: error during ctx access conversion (0)This is happening because offset 60 in bpf_sock_addr corresponds to animplicit padding of 4 bytes, right after msg_src_ip4. Access to thispadding isn't rejected in sock_addr_is_valid_access and it thus laterfails to convert the access.This patch fixes it by explicitly checking the various fields ofbpf_sock_addr in sock_addr_is_valid_access.I checked the other ctx structures and is_valid_access functions anddidn't find any other similar cases. Other cases of (properly handled)padding are covered in new tests in a subsequent patch.

CVE-2025-40100 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: do not assert we found block group item when creating free space treeCurrently, when building a free space tree at populate_free_space_tree(),if we are not using the block group tree feature, we always expect to findblock group items (either extent items or a block group item with key typeBTRFS_BLOCK_GROUP_ITEM_KEY) when we search the extent tree withbtrfs_search_slot_for_read(), so we assert that we found an item. Howeverthis expectation is wrong since we can have a new block group created inthe current transaction which is still empty and for which we still havenot added the block group's item to the extent tree, in which case we donot have any items in the extent tree associated to the block group.The insertion of a new block group's block group item in the extent treehappens at btrfs_create_pending_block_groups() when it calls the helperinsert_block_group_item(). This typically is done when a transactionhandle is released, committed or when running delayed refs (either aspart of a transaction commit or when serving tickets for space reservationif we are low on free space).So remove the assertion at populate_free_space_tree() even when the blockgroup tree feature is not enabled and update the comment to mention thiscase.Syzbot reported this with the following stack trace: BTRFS info (device loop3 state M): rebuilding free space tree assertion failed: ret == 0 :: 0, in fs/btrfs/free-space-tree.c:1115 ------------[ cut here ]------------ kernel BUG at fs/btrfs/free-space-tree.c:1115!

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

CVE-2025-40120 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: usb: asix: hold PM usage ref to avoid PM/MDIO + RTNL deadlockPrevent USB runtime PM (autosuspend) for AX88772* in bind.usbnet enables runtime PM (autosuspend) by default, so disabling it viathe usb_driver flag is ineffective. On AX88772B, autosuspend shows nomeasurable power saving with current driver (no link partner, adminup/down). The ~0.453 W -> ~0.248 W drop on v6.1 comes from phylib poweringthe PHY off on admin-down, not from USB autosuspend.The real hazard is that with runtime PM enabled, ndo_open() (under RTNL)may synchronously trigger autoresume (usb_autopm_get_interface()) intoasix_resume() while the USB PM lock is held. Resume paths then invokephylink/phylib and MDIO, which also expect RTNL, leading to possibledeadlocks or PM lock vs MDIO wake issues.To avoid this, keep the device runtime-PM active by taking a usagereference in ax88772_bind() and dropping it in unbind(). A non-zero PMusage count blocks runtime suspend regardless of userspace policy(.../power/control - pm_runtime_allow/forbid), making this approachrobust against sysfs overrides.Holding a runtime-PM usage ref does not affect system-wide suspend;system sleep/resume callbacks continue to run as before.

CVE-2025-40123 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Enforce expected_attach_type for tailcall compatibilityYinhao et al. recently reported: Our fuzzer tool discovered an uninitialized pointer issue in the bpf_prog_test_run_xdp() function within the Linux kernel's BPF subsystem. This leads to a NULL pointer dereference when a BPF program attempts to deference the txq member of struct xdp_buff object.The test initializes two programs of BPF_PROG_TYPE_XDP: progA acts as theentry point for bpf_prog_test_run_xdp() and its expected_attach_type canneither be of be BPF_XDP_DEVMAP nor BPF_XDP_CPUMAP. progA calls into a slotof a tailcall map it owns. progB's expected_attach_type must be BPF_XDP_DEVMAPto pass xdp_is_valid_access() validation. The program returns struct xdp_md'segress_ifindex, and the latter is only allowed to be accessed under mentionedexpected_attach_type. progB is then inserted into the tailcall which progAcalls.The underlying issue goes beyond XDP though. Another example are programsof type BPF_PROG_TYPE_CGROUP_SOCK_ADDR. sock_addr_is_valid_access() as wellas sock_addr_func_proto() have different logic depending on the programs'expected_attach_type. Similarly, a program attached to BPF_CGROUP_INET4_GETPEERNAMEshould not be allowed doing a tailcall into a program which calls bpf_bind()out of BPF which is only enabled for BPF_CGROUP_INET4_CONNECT.In short, specifying expected_attach_type allows to open up additionalfunctionality or restrictions beyond what the basic bpf_prog_type enables.The use of tailcalls must not violate these constraints. Fix it by enforcingexpected_attach_type in __bpf_prog_map_compatible().Note that we only enforce this for tailcall maps, but not for BPF devmaps orcpumaps: There, the programs are invoked through dev_map_bpf_prog_run*() andcpu_map_bpf_prog_run*() which set up a new environment / context and thereforethese situations are not prone to this issue.

The unvalidated out-of-orderextents then trigger a BUG_ON in ext4_es_cache_extent() due to integerunderflow when calculating hole sizes.Fix this by detecting this invalid flag combination early in ext4_iget()and rejecting the corrupted inode.

CVE-2025-40223 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:most: usb: Fix use-after-free in hdm_disconnecthdm_disconnect() calls most_deregister_interface(), which eventuallyunregisters the MOST interface device with device_unregister(iface->dev).If that drops the last reference, the device core may call release_mdev()immediately while hdm_disconnect() is still executing.The old code also freed several mdev-owned allocations inhdm_disconnect() and then performed additional put_device() calls.Depending on refcount order, this could lead to use-after-free ordouble-free when release_mdev() ran (or when unregister paths alsoperformed puts).Fix by moving the frees of mdev-owned allocations into release_mdev(),so they happen exactly once when the device is truly released, and bydropping the extra put_device() calls in hdm_disconnect() that areredundant after device_unregister() and most_deregister_interface().This addresses the KASAN slab-use-after-free reported by syzbot inhdm_disconnect().

CVE-2025-40248 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:vsock: Ignore signal/timeout on connect() if already establishedDuring connect(), acting on a signal/timeout by disconnecting an alreadyestablished socket leads to several issues:1. connect() invoking vsock_transport_cancel_pkt() -> virtio_transport_purge_skbs() may race with sendmsg() invoking virtio_transport_get_credit(). This results in a permanently elevated `vvs->bytes_unsent`. Which, in turn, confuses the SOCK_LINGER handling.2. connect() resetting a connected socket's state may race with socket being placed in a sockmap. A disconnected socket remaining in a sockmap breaks sockmap's assumptions. And gives rise to WARNs.3. connect() transitioning SS_CONNECTED -> SS_UNCONNECTED allows for a transport change/drop after TCP_ESTABLISHED. Which poses a problem for any simultaneous sendmsg() or connect() and may result in a use-after-free/null-ptr-deref.Do not disconnect socket on signal/timeout. Keep the logic for unconnectedsockets: they don't linger, can't be placed in a sockmap, are rejected bysendmsg().[1]: https://lore.kernel.org/netdev/e07fd95c-9a38-4eea-9638-133e38c2ec9b@rbox.co/[2]: https://lore.kernel.org/netdev/20250317-vsock-trans-signal-race-v4-0-fc8837f3f1d4@rbox.co/[3]: https://lore.kernel.org/netdev/60f1b7db-3099-4f6a-875e-af9f6ef194f6@rbox.co/

Description: In the Linux kernel, the following vulnerability has been resolved:devlink: rate: Unset parent pointer in devl_rate_nodes_destroyThe function devl_rate_nodes_destroy is documented to "Unset parent forall rate objects". However, it was only calling the driver-specific`rate_leaf_parent_set` or `rate_node_parent_set` ops and decrementingthe parent's refcount, without actually setting the`devlink_rate->parent` pointer to NULL.This leaves a dangling pointer in the `devlink_rate` struct, which causerefcount error in netdevsim[1] and mlx5[2]. In addition, this isinconsistent with the behavior of `devlink_nl_rate_parent_node_set`,where the parent pointer is correctly cleared.This patch fixes the issue by explicitly setting `devlink_rate->parent`to NULL after notifying the driver, thus fulfilling the function'sdocumented behavior for all rate objects.[1]repro steps:echo 1 > /sys/bus/netdevsim/new_devicedevlink dev eswitch set netdevsim/netdevsim1 mode switchdevecho 1 > /sys/bus/netdevsim/devices/netdevsim1/sriov_numvfsdevlink port function rate add netdevsim/netdevsim1/test_nodedevlink port function rate set netdevsim/netdevsim1/128 parent test_nodeecho 1 > /sys/bus/netdevsim/del_devicedmesg:refcount_t: decrement hit 0; leaking memory.WARNING: CPU: 8 PID: 1530 at lib/refcount.c:31 refcount_warn_saturate+0x42/0xe0CPU: 8 UID: 0 PID: 1530 Comm: bash Not tainted 6.18.0-rc4+ #1 NONEHardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.16.0-0-gd239552ce722-prebuilt.qemu.org 04/01/2014RIP: 0010:refcount_warn_saturate+0x42/0xe0Call Trace: devl_rate_leaf_destroy+0x8d/0x90 __nsim_dev_port_del+0x6c/0x70 [netdevsim] nsim_dev_reload_destroy+0x11c/0x140 [netdevsim] nsim_drv_remove+0x2b/0xb0 [netdevsim] device_release_driver_internal+0x194/0x1f0 bus_remove_device+0xc6/0x130 device_del+0x159/0x3c0 device_unregister+0x1a/0x60 del_device_store+0x111/0x170 [netdevsim] kernfs_fop_write_iter+0x12e/0x1e0 vfs_write+0x215/0x3d0 ksys_write+0x5f/0xd0 do_syscall_64+0x55/0x10f0 entry_SYSCALL_64_after_hwframe+0x4b/0x53[2]devlink dev eswitch set pci/0000:08:00.0 mode switchdevdevlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 1000devlink port function rate add pci/0000:08:00.0/group1devlink port function rate set pci/0000:08:00.0/32768 parent group1modprobe -r mlx5_ib mlx5_fwctl mlx5_coredmesg:refcount_t: decrement hit 0; leaking memory.WARNING: CPU: 7 PID: 16151 at lib/refcount.c:31 refcount_warn_saturate+0x42/0xe0CPU: 7 UID: 0 PID: 16151 Comm: bash Not tainted 6.17.0-rc7_for_upstream_min_debug_2025_10_02_12_44 #1 NONEHardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014RIP: 0010:refcount_warn_saturate+0x42/0xe0Call Trace: devl_rate_leaf_destroy+0x8d/0x90 mlx5_esw_offloads_devlink_port_unregister+0x33/0x60 [mlx5_core] mlx5_esw_offloads_unload_rep+0x3f/0x50 [mlx5_core] mlx5_eswitch_unload_sf_vport+0x40/0x90 [mlx5_core] mlx5_sf_esw_event+0xc4/0x120 [mlx5_core] notifier_call_chain+0x33/0xa0 blocking_notifier_call_chain+0x3b/0x50 mlx5_eswitch_disable_locked+0x50/0x110 [mlx5_core] mlx5_eswitch_disable+0x63/0x90 [mlx5_core] mlx5_unload+0x1d/0x170 [mlx5_core] mlx5_uninit_one+0xa2/0x130 [mlx5_core] remove_one+0x78/0xd0 [mlx5_core] pci_device_remove+0x39/0xa0 device_release_driver_internal+0x194/0x1f0 unbind_store+0x99/0xa0 kernfs_fop_write_iter+0x12e/0x1e0 vfs_write+0x215/0x3d0 ksys_write+0x5f/0xd0 do_syscall_64+0x53/0x1f0 entry_SYSCALL_64_after_hwframe+0x4b/0x53

CVE-2025-40254 Severity: Moderate CVSS3 score: 5.5

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-audio: Fix potential overflow of PCM transfer bufferThe PCM stream data in USB-audio driver is transferred over USB URBpacket buffers, and each packet size is determined dynamically. Thepacket sizes are limited by some factors such as wMaxPacketSize USBdescriptor. OTOH, in the current code, the actually used packet sizesare determined only by the rate and the PPS, which may be bigger thanthe size limit above. This results in a buffer overflow, as reportedby syzbot.Basically when the limit is smaller than the calculated packet size,it implies that something is wrong, most likely a weird USBdescriptor. So the best option would be just to return an error atthe parameter setup time before doing any further operations.This patch introduces such a sanity check, and returns -EINVAL whenthe packet size is greater than maxpacksize. The comparison withep->packsize[1] alone should suffice since it's always equal orgreater than ep->packsize[0].

Description: In the Linux kernel, the following vulnerability has been resolved:mm/secretmem: fix use-after-free race in fault handlerWhen a page fault occurs in a secret memory file created with`memfd_secret(2)`, the kernel will allocate a new folio for it, mark theunderlying page as not-present in the direct map, and add it to the filemapping.If two tasks cause a fault in the same page concurrently, both could endup allocating a folio and removing the page from the direct map, but onlyone would succeed in adding the folio to the file mapping. The task thatfailed undoes the effects of its attempt by (a) freeing the folio againand (b) putting the page back into the direct map. However, by doingthese two operations in this order, the page becomes available to theallocator again before it is placed back in the direct mapping.If another task attempts to allocate the page between (a) and (b), and thekernel tries to access it via the direct map, it would result in asupervisor not-present page fault.Fix the ordering to restore the direct map before the folio is freed.

CVE-2025-40275 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-audio: Fix NULL pointer dereference in snd_usb_mixer_controls_baddIn snd_usb_create_streams(), for UAC version 3 devices, the InterfaceAssociation Descriptor (IAD) is retrieved via usb_ifnum_to_if(). If thiscall fails, a fallback routine attempts to obtain the IAD from the nextinterface and sets a BADD profile. However, snd_usb_mixer_controls_badd()assumes that the IAD retrieved from usb_ifnum_to_if() is always valid,without performing a NULL check. This can lead to a NULL pointerdereference when usb_ifnum_to_if() fails to find the interface descriptor.This patch adds a NULL pointer check after calling usb_ifnum_to_if() insnd_usb_mixer_controls_badd() to prevent the dereference.This issue was discovered by syzkaller, which triggered the bug by sendinga crafted USB device descriptor.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amdgpu: Fix NULL pointer dereference in VRAM logic for APU devicesPreviously, APU platforms (and other scenarios with uninitialized VRAM managers)triggered a NULL pointer dereference in `ttm_resource_manager_usage()`. The rootcause is not that the `struct ttm_resource_manager *man` pointer itself is NULL,but that `man->bdev` (the backing device pointer within the manager) remainsuninitialized (NULL) on APUs-since APUs lack dedicated VRAM and do not fullyset up VRAM manager structures. When `ttm_resource_manager_usage()` attempts toacquire `man->bdev->lru_lock`, it dereferences the NULL `man->bdev`, leading toa kernel OOPS.1. **amdgpu_cs.c**: Extend the existing bandwidth control check in `amdgpu_cs_get_threshold_for_moves()` to include a check for `ttm_resource_manager_used()`. If the manager is not used (uninitialized `bdev`), return 0 for migration thresholds immediately-skipping VRAM-specific logic that would trigger the NULL dereference.2. **amdgpu_kms.c**: Update the `AMDGPU_INFO_VRAM_USAGE` ioctl and memory info reporting to use a conditional: if the manager is used, return the real VRAM usage; otherwise, return 0. This avoids accessing `man->bdev` when it is NULL.3. **amdgpu_virt.c**: Modify the vf2pf (virtual function to physical function) data write path. Use `ttm_resource_manager_used()` to check validity: if the manager is usable, calculate `fb_usage` from VRAM usage; otherwise, set `fb_usage` to 0 (APUs have no discrete framebuffer to report).This approach is more robust than APU-specific checks because it:- Works for all scenarios where the VRAM manager is uninitialized (not just APUs),- Aligns with TTM's design by using its native helper function,- Preserves correct behavior for discrete GPUs (which have fully initialized `man->bdev` and pass the `ttm_resource_manager_used()` check).v4: use ttm_resource_manager_used(&adev->mman.vram_mgr.manager) instead of checking the adev->gmc.is_app_apu flag (Christian)

Description: In the Linux kernel, the following vulnerability has been resolved:fbdev: Add bounds checking in bit_putcs to fix vmalloc-out-of-boundsAdd bounds checking to prevent writes past framebuffer boundaries whenrendering text near screen edges. Return early if the Y position is off-screenand clip image height to screen boundary. Break from the rendering loop if theX position is off-screen. When clipping image width to fit the screen, updatethe character count to match the clipped width to prevent buffer sizemismatches.Without the character count update, bit_putcs_aligned and bit_putcs_unalignedreceive mismatched parameters where the buffer is allocated for the clippedwidth but cnt reflects the original larger count, causing out-of-bounds writes.

Description: In the Linux kernel, the following vulnerability has been resolved:exfat: validate cluster allocation bits of the allocation bitmapsyzbot created an exfat image with cluster bits not set for the allocationbitmap. exfat-fs reads and uses the allocation bitmap without checkingthis. The problem is that if the start cluster of the allocation bitmapis 6, cluster 6 can be allocated when creating a directory with mkdir.exfat zeros out this cluster in exfat_mkdir, which can delete existingentries. This can reallocate the allocated entries. In addition,the allocation bitmap is also zeroed out, so cluster 6 can be reallocated.This patch adds exfat_test_bitmap_range to validate that clusters used forthe allocation bitmap are correctly marked as in-use.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: brcmfmac: fix crash while sending Action Frames in standalone AP ModeCurrently, whenever there is a need to transmit an Action frame,the brcmfmac driver always uses the P2P vif to send the "actframe" IOVAR tofirmware. The P2P interfaces were available when wpa_supplicant is managingthe wlan interface.However, the P2P interfaces are not created/initialized when only hostapdis managing the wlan interface. And if hostapd receives an ANQP Query REQAction frame even from an un-associated STA, the brcmfmac driver triesto use an uninitialized P2P vif pointer for sending the IOVAR to firmware.This NULL pointer dereferencing triggers a driver crash.

Because the former function would not get executedwhen only hostapd is managing wlan interface, and it is not safe to doreinit_completion() later in brcmf_p2p_tx_action_frame(), without any priorinit_completion().And in the brcmf_p2p_tx_action_frame() function, the condition check forP2P Presence response frame is not needed, since the wpa_supplicant isproperly sending the P2P Presense Response frame on the P2P-GO vif insteadof the P2P-Device vif.[Cc stable]

Description: In the Linux kernel, the following vulnerability has been resolved:net: stmmac: Correctly handle Rx checksum offload errorsThe stmmac_rx function would previously set skb->ip_summed toCHECKSUM_UNNECESSARY if hardware checksum offload (CoE) was enabledand the packet was of a known IP ethertype.However, this logic failed to check if the hardware had actuallyreported a checksum error. The hardware status, indicating a header orpayload checksum failure, was being ignored at this stage. This couldcause corrupt packets to be passed up the network stack as valid.This patch corrects the logic by checking the `csum_none` status flag,which is set when the hardware reports a checksum error. If this flagis set, skb->ip_summed is now correctly set to CHECKSUM_NONE,ensuring the kernel's network stack will perform its own validation andproperly handle the corrupt packet.

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

Description: In the Linux kernel, the following vulnerability has been resolved:futex: Don't leak robust_list pointer on exec racesys_get_robust_list() and compat_get_robust_list() use ptrace_may_access()to check if the calling task is allowed to access another task'srobust_list pointer. This check is racy against a concurrent exec() in thetarget process.During exec(), a task may transition from a non-privileged binary to aprivileged one (e.g., setuid binary) and its credentials/memory mappingsmay change. If get_robust_list() performs ptrace_may_access() beforethis transition, it may erroneously allow access to sensitive informationafter the target becomes privileged.A racy access allows an attacker to exploit a window during whichptrace_may_access() passes before a target process transitions to aprivileged state via exec().For example, consider a non-privileged task T that is about to execute asetuid-root binary. An attacker task A calls get_robust_list(T) while Tis still unprivileged. Since ptrace_may_access() checks permissionsbased on current credentials, it succeeds. However, if T begins execimmediately afterwards, it becomes privileged and may change its memorymappings. Because get_robust_list() proceeds to access T->robust_listwithout synchronizing with exec() it may read user-space pointers from anow-privileged process.This violates the intended post-exec access restrictions and couldexpose sensitive memory addresses or be used as a primitive in a largerexploit chain. Consequently, the race can lead to unauthorizeddisclosure of information across privilege boundaries and poses apotential security risk.Take a read lock on signal->exec_update_lock prior to invokingptrace_may_access() and accessing the robust_list/compat_robust_list.This ensures that the target task's exec state remains stable during thecheck, allowing for consistent and synchronized validation ofcredentials.

Description: In the Linux kernel, the following vulnerability has been resolved:arch_topology: Fix incorrect error check in topology_parse_cpu_capacity()Fix incorrect use of PTR_ERR_OR_ZERO() in topology_parse_cpu_capacity()which causes the code to proceed with NULL clock pointers. The currentlogic uses !PTR_ERR_OR_ZERO(cpu_clk) which evaluates to true for bothvalid pointers and NULL, leading to potential NULL pointer dereferencein clk_get_rate().Per include/linux/err.h documentation, PTR_ERR_OR_ZERO(ptr) returns:"The error code within @ptr if it is an error pointer; 0 otherwise."This means PTR_ERR_OR_ZERO() returns 0 for both valid pointers AND NULLpointers. Therefore !PTR_ERR_OR_ZERO(cpu_clk) evaluates to true (proceed)when cpu_clk is either valid or NULL, causing clk_get_rate(NULL) to becalled when of_clk_get() returns NULL.Replace with !IS_ERR_OR_NULL(cpu_clk) which only proceeds for validpointers, preventing potential NULL pointer dereference in clk_get_rate().

The writer detects that aread lock is already held and is scheduled out. However, readers underenetc_poll cannot acquire the read lock again because a writer is alreadywaiting, leading to a thread hang.Currently, the deadlock is avoided by adjusting enetc_lock_mdio to preventrecursive lock acquisition.

CVE-2025-68209 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mlx5: Fix default values in create CQCurrently, CQs without a completion function are assigned themlx5_add_cq_to_tasklet function by default. This is problematic sinceonly user CQs created through the mlx5_ib driver are intended to usethis function.Additionally, all CQs that will use doorbells instead of polling forcompletions must call mlx5_cq_arm. However, the default CQ creation flowleaves a valid value in the CQ's arm_db field, allowing FW to sendinterrupts to polling-only CQs in certain corner cases.These two factors would allow a polling-only kernel CQ to be triggeredby an EQ interrupt and call a completion function intended only for userCQs, causing a null pointer exception.Some areas in the driver have prevented this issue with one-off fixesbut did not address the root cause.This patch fixes the described issue by adding defaults to the create CQflow. It adds a default dummy completion function to protect againstnull pointer exceptions, and it sets an invalid command sequence numberby default in kernel CQs to prevent the FW from sending an interrupt tothe CQ until it is armed. User CQs are responsible for their owninitialization values.Callers of mlx5_core_create_cq are responsible for changing thecompletion function and arming the CQ per their needs.

Description: In the Linux kernel, the following vulnerability has been resolved:ksm: use range-walk function to jump over holes in scan_get_next_rmap_itemCurrently, scan_get_next_rmap_item() walks every page address in a VMA tolocate mergeable pages. This becomes highly inefficient when scanninglarge virtual memory areas that contain mostly unmapped regions, causingksmd to use large amount of cpu without deduplicating much pages.This patch replaces the per-address lookup with a range walk usingwalk_page_range(). The range walker allows KSM to skip over entireunmapped holes in a VMA, avoiding unnecessary lookups. This problem waspreviously discussed in [1].Consider the following test program which creates a 32 TiB mapping in thevirtual address space but only populates a single page:#include #include #include /* 32 TiB */const size_t size = 32ul * 1024 * 1024 * 1024 * 1024;int main() { char *area = mmap(NULL, size, PROT_READ | PROT_WRITE, MAP_NORESERVE | MAP_PRIVATE | MAP_ANON, -1, 0); if (area == MAP_FAILED) { perror("mmap() failed\n"); return -1; } /* Populate a single page such that we get an anon_vma. */ *area = 0; /* Enable KSM. */ madvise(area, size, MADV_MERGEABLE); pause(); return 0;}$ ./ksm-sparse &$ echo 1 > /sys/kernel/mm/ksm/run Without this patch ksmd uses 100% of the cpu for a long time (more then 1hour in my test machine) scanning all the 32 TiB virtual address spacethat contain only one mapped page. This makes ksmd essentially deadlockednot able to deduplicate anything of value. With this patch ksmd walksonly the one mapped page and skips the rest of the 32 TiB virtual addressspace, making the scan fast using little cpu.

CVE-2025-68214 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:timers: Fix NULL function pointer race in timer_shutdown_sync()There is a race condition between timer_shutdown_sync() and timerexpiration that can lead to hitting a WARN_ON in expire_timers().The issue occurs when timer_shutdown_sync() clears the timer functionto NULL while the timer is still running on another CPU. The racescenario looks like this:CPU0 CPU1 lock_timer_base() expire_timers() base->running_timer = timer; unlock_timer_base() [call_timer_fn enter] mod_timer() ...timer_shutdown_sync()lock_timer_base()// For now, will not detach the timer but only clear its function to NULLif (base->running_timer != timer) ret = detach_if_pending(timer, base, true);if (shutdown) timer->function = NULL;unlock_timer_base() [call_timer_fn exit] lock_timer_base() base->running_timer = NULL; unlock_timer_base() ... // Now timer is pending while its function set to NULL. // next timer trigger expire_timers() WARN_ON_ONCE(!fn) // hit ...lock_timer_base()// Now timer will detachif (base->running_timer != timer) ret = detach_if_pending(timer, base, true);if (shutdown) timer->function = NULL;unlock_timer_base()The problem is that timer_shutdown_sync() clears the timer functionregardless of whether the timer is currently running. This can leave apending timer with a NULL function pointer, which triggers theWARN_ON_ONCE(!fn) check in expire_timers().Fix this by only clearing the timer function when actually detaching thetimer. If the timer is running, leave the function pointer intact, which issafe because the timer will be properly detached when it finishes running.

CVE-2025-68219 Severity: Moderate CVSS3 score: 5.5

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

Description: In the Linux kernel, the following vulnerability has been resolved: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:comedi: check device's attached status in compat ioctlsSyzbot identified an issue [1] that crashes kernel, seemingly due tounexistent callback dev->get_valid_routes(). By all means, this shouldnot occur as said callback must always be set toget_zero_valid_routes() in __comedi_device_postconfig().As the crash seems to appear exclusively in i386 kernels, at least,judging from [1] reports, the blame lies with compat versionsof standard IOCTL handlers. Several of them are modified anddo not use comedi_unlocked_ioctl(). While functionality of theseioctls essentially copy their original versions, they do nothave required sanity check for device's attached status. This,in turn, leads to a possibility of calling select IOCTLs on adevice that has not been properly setup, even via COMEDI_DEVCONFIG.Doing so on unconfigured devices means that several crucial stepsare missed, for instance, specifying dev->get_valid_routes()callback.Fix this somewhat crudely by ensuring device's attached status beforeperforming any ioctls, improving logic consistency between modernand compat functions.[1] Syzbot report:BUG: kernel NULL pointer dereference, address: 0000000000000000...CR2: ffffffffffffffd6 CR3: 000000006c717000 CR4: 0000000000352ef0Call Trace: get_valid_routes drivers/comedi/comedi_fops.c:1322 [inline] parse_insn+0x78c/0x1970 drivers/comedi/comedi_fops.c:1401 do_insnlist_ioctl+0x272/0x700 drivers/comedi/comedi_fops.c:1594 compat_insnlist drivers/comedi/comedi_fops.c:3208 [inline] comedi_compat_ioctl+0x810/0x990 drivers/comedi/comedi_fops.c:3273 __do_compat_sys_ioctl fs/ioctl.c:695 [inline] __se_compat_sys_ioctl fs/ioctl.c:638 [inline] __ia32_compat_sys_ioctl+0x242/0x370 fs/ioctl.c:638 do_syscall_32_irqs_on arch/x86/entry/syscall_32.c:83 [inline]...

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: multiq3: sanitize config options in multiq3_attach()Syzbot identified an issue [1] in multiq3_attach() that induces atask timeout due to open() or COMEDI_DEVCONFIG ioctl operations,specifically, in the case of multiq3 driver.This problem arose when syzkaller managed to craft weird configurationoptions used to specify the number of channels in encoder subdevice.If a particularly great number is passed to s->n_chan inmultiq3_attach() via it->options[2], then multiple calls tomultiq3_encoder_reset() at the end of driver-specific attach() methodwill be running for minutes, thus blocking tasks and affected devicesas well.While this issue is most likely not too dangerous for real-lifedevices, it still makes sense to sanitize configuration inputs. Enablea sensible limit on the number of encoder chips (4 chips max, eachwith 2 channels) to stop this behaviour from manifesting.[1] Syzbot crash:INFO: task syz.2.19:6067 blocked for more than 143 seconds....Call Trace: context_switch kernel/sched/core.c:5254 [inline] __schedule+0x17c4/0x4d60 kernel/sched/core.c:6862 __schedule_loop kernel/sched/core.c:6944 [inline] schedule+0x165/0x360 kernel/sched/core.c:6959 schedule_preempt_disabled+0x13/0x30 kernel/sched/core.c:7016 __mutex_lock_common kernel/locking/mutex.c:676 [inline] __mutex_lock+0x7e6/0x1350 kernel/locking/mutex.c:760 comedi_open+0xc0/0x590 drivers/comedi/comedi_fops.c:2868 chrdev_open+0x4cc/0x5e0 fs/char_dev.c:414 do_dentry_open+0x953/0x13f0 fs/open.c:965 vfs_open+0x3b/0x340 fs/open.c:1097...

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: udc: fix use-after-free in usb_gadget_state_workA race condition during gadget teardown can lead to a use-after-freein usb_gadget_state_work(), as reported by KASAN: BUG: KASAN: invalid-access in sysfs_notify+0x2c/0xd0 Workqueue: events usb_gadget_state_workThe fundamental race occurs because a concurrent event (e.g., aninterrupt) can call usb_gadget_set_state() and schedule gadget->workat any time during the cleanup process in usb_del_gadget().Commit 399a45e5237c ("usb: gadget: core: flush gadget workqueue afterdevice removal") attempted to fix this by moving flush_work() to afterdevice_del(). However, this does not fully solve the race, as a newwork item can still be scheduled *after* flush_work() completes butbefore the gadget's memory is freed, leading to the same use-after-free.This patch fixes the race condition robustly by introducing a 'teardown'flag and a 'state_lock' spinlock to the usb_gadget struct. The flag isset during cleanup in usb_del_gadget() *before* calling flush_work() toprevent any new work from being scheduled once cleanup has commenced.The scheduling site, usb_gadget_set_state(), now checks this flag underthe lock before queueing the work, thus safely closing the race window.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: dwc3: Fix race condition between concurrent dwc3_remove_requests() call pathsThis patch addresses a race condition caused by unsynchronizedexecution of multiple call paths invoking `dwc3_remove_requests()`,leading to premature freeing of USB requests and subsequent crashes.Three distinct execution paths interact with `dwc3_remove_requests()`:Path 1:Triggered via `dwc3_gadget_reset_interrupt()` during USB resethandling. The call stack includes:- `dwc3_ep0_reset_state()`- `dwc3_ep0_stall_and_restart()`- `dwc3_ep0_out_start()`- `dwc3_remove_requests()`- `dwc3_gadget_del_and_unmap_request()`Path 2:Also initiated from `dwc3_gadget_reset_interrupt()`, but through`dwc3_stop_active_transfers()`. The call stack includes:- `dwc3_stop_active_transfers()`- `dwc3_remove_requests()`- `dwc3_gadget_del_and_unmap_request()`Path 3:Occurs independently during `adb root` execution, which triggersUSB function unbind and bind operations. The sequence includes:- `gserial_disconnect()`- `usb_ep_disable()`- `dwc3_gadget_ep_disable()`- `dwc3_remove_requests()` with `-ESHUTDOWN` statusPath 3 operates asynchronously and lacks synchronization with Paths1 and 2. When Path 3 completes, it disables endpoints and frees 'out'requests. If Paths 1 or 2 are still processing these requests,accessing freed memory leads to a crash due to use-after-free conditions.To fix this added check for request completion and skip processingif already completed and added the request status for ep0 while queue.

CVE-2025-68296 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:drm, fbcon, vga_switcheroo: Avoid race condition in fbcon setupProtect vga_switcheroo_client_fb_set() with console lock. Avoids OOBaccess in fbcon_remap_all(). Without holding the console lock the callraces with switching outputs.VGA switcheroo calls fbcon_remap_all() when switching clients. The fbconfunction uses struct fb_info.node, which is set by register_framebuffer().As the fb-helper code currently sets up VGA switcheroo before registeringthe framebuffer, the value of node is -1 and therefore not a legal value.For example, fbcon uses the value within set_con2fb_map() [1] as an indexinto an array.Moving vga_switcheroo_client_fb_set() after register_framebuffer() canresult in VGA switching that does not switch fbcon correctly.Therefore move vga_switcheroo_client_fb_set() under fbcon_fb_registered(),which already holds the console lock. Fbdev calls fbcon_fb_registered()from within register_framebuffer(). Serializes the helper with VGAswitcheroo's call to fbcon_remap_all().Although vga_switcheroo_client_fb_set() takes an instance of struct fb_infoas parameter, it really only needs the contained fbcon state. Moving thecall to fbcon initialization is therefore cleaner than before. Only amdgpu,i915, nouveau and radeon support vga_switcheroo. For all other drivers,this change does nothing.

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.

CVE-2025-68308 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:can: kvaser_usb: leaf: Fix potential infinite loop in command parsersThe `kvaser_usb_leaf_wait_cmd()` and `kvaser_usb_leaf_read_bulk_callback`functions contain logic to zero-length commands. These commands are usedto align data to the USB endpoint's wMaxPacketSize boundary.The driver attempts to skip these placeholders by aligning the bufferposition `pos` to the next packet boundary using `round_up()` function.However, if zero-length command is found exactly on a packet boundary(i.e., `pos` is a multiple of wMaxPacketSize, including 0), `round_up`function will return the unchanged value of `pos`. This prevents `pos`to be increased, causing an infinite loop in the parsing logic.This patch fixes this in the function by using `pos + 1` instead.This ensures that even if `pos` is on a boundary, the calculation isbased on `pos + 1`, forcing `round_up()` to always return the nextaligned boundary.

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-2025-68371 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: smartpqi: Fix device resources accessed after device removalCorrect possible race conditions during device removal.Previously, a scheduled work item to reset a LUN could still executeafter the device was removed, leading to use-after-free and otherresource access issues.This race condition occurs because the abort handler may schedule a LUNreset concurrently with device removal via sdev_destroy(), leading touse-after-free and improper access to freed resources. - Check in the device reset handler if the device is still present in the controller's SCSI device list before running; if not, the reset is skipped. - Cancel any pending TMF work that has not started in sdev_destroy(). - Ensure device freeing in sdev_destroy() is done while holding the LUN reset mutex to avoid races with ongoing resets.

This makes sure theconfig cannot be freed while recv_work is still running, even if clear+ reconfigure interleave.In addition, we don't need to worry about recv_work dropping the lastnbd_put (which causes deadlock):path A (netlink with NBD_CFLAG_DESTROY_ON_DISCONNECT): connect // nbd_refs=1 (trigger recv_work) open nbd // nbd_refs=2 NBD_CLEAR_SOCK close nbd nbd_release nbd_disconnect_and_put flush_workqueue // recv_work done nbd_config_put nbd_put // nbd_refs=1 nbd_put // nbd_refs=0 queue_workpath B (netlink without NBD_CFLAG_DESTROY_ON_DISCONNECT): connect // nbd_refs=2 (trigger recv_work) open nbd // nbd_refs=3 NBD_CLEAR_SOCK // conf_refs=2 close nbd nbd_release nbd_config_put // conf_refs=1 nbd_put // nbd_refs=2 recv_work done // conf_refs=0, nbd_refs=1 rmmod // nbd_refs=0Depends-on: e2daec488c57 ("nbd: Fix hungtask when nbd_config_put")

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

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

CVE-2025-68740 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ima: Handle error code returned by ima_filter_rule_match()In ima_match_rules(), if ima_filter_rule_match() returns -ENOENT due tothe rule being NULL, the function incorrectly skips the 'if (!rc)' checkand sets 'result = true'. The LSM rule is considered a match, causingextra files to be measured by IMA.This issue can be reproduced in the following scenario:After unloading the SELinux policy module via 'semodule -d', if an IMAmeasurement is triggered before ima_lsm_rules is updated,in ima_match_rules(), the first call to ima_filter_rule_match() returns-ESTALE. This causes the code to enter the 'if (rc == -ESTALE &&!rule_reinitialized)' block, perform ima_lsm_copy_rule() and retry. Inima_lsm_copy_rule(), since the SELinux module has been removed, the rulebecomes NULL, and the second call to ima_filter_rule_match() returns-ENOENT. This bypasses the 'if (!rc)' check and results in a false match.Call trace: selinux_audit_rule_match+0x310/0x3b8 security_audit_rule_match+0x60/0xa0 ima_match_rules+0x2e4/0x4a0 ima_match_policy+0x9c/0x1e8 ima_get_action+0x48/0x60 process_measurement+0xf8/0xa98 ima_bprm_check+0x98/0xd8 security_bprm_check+0x5c/0x78 search_binary_handler+0x6c/0x318 exec_binprm+0x58/0x1b8 bprm_execve+0xb8/0x130 do_execveat_common.isra.0+0x1a8/0x258 __arm64_sys_execve+0x48/0x68 invoke_syscall+0x50/0x128 el0_svc_common.constprop.0+0xc8/0xf0 do_el0_svc+0x24/0x38 el0_svc+0x44/0x200 el0t_64_sync_handler+0x100/0x130 el0t_64_sync+0x3c8/0x3d0Fix this by changing 'if (!rc)' to 'if (rc <= 0)' to ensure that errorcodes like -ENOENT do not bypass the check and accidentally result in asuccessful match.

Description: In the Linux kernel, the following vulnerability has been resolved:hfsplus: Verify inode mode when loading from disksyzbot is reporting that S_IFMT bits of inode->i_mode can become bogus whenthe S_IFMT bits of the 16bits "mode" field loaded from disk are corrupted.According to [1], the permissions field was treated as reserved in Mac OS8 and 9. According to [2], the reserved field was explicitly initializedwith 0, and that field must remain 0 as long as reserved. Therefore, whenthe "mode" field is not 0 (i.e. no longer reserved), the file must beS_IFDIR if dir == 1, and the file must be one of S_IFREG/S_IFLNK/S_IFCHR/S_IFBLK/S_IFIFO/S_IFSOCK if dir == 0.

CVE-2025-68780 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:sched/deadline: only set free_cpus for online runqueuesCommit 16b269436b72 ("sched/deadline: Modify cpudl::free_cpusto reflect rd->online") introduced the cpudl_set/clear_freecpufunctions to allow the cpu_dl::free_cpus mask to be manipulatedby the deadline scheduler class rq_on/offline callbacks so themask would also reflect this state.Commit 9659e1eeee28 ("sched/deadline: Remove cpu_active_maskfrom cpudl_find()") removed the check of the cpu_active_mask tosave some processing on the premise that the cpudl::free_cpusmask already reflected the runqueue online state.Unfortunately, there are cases where it is possible for thecpudl_clear function to set the free_cpus bit for a CPU when thedeadline runqueue is offline. When this occurs while a CPU isconnected to the default root domain the flag may retain the badstate after the CPU has been unplugged. Later, a different CPUthat is transitioning through the default root domain may push adeadline task to the powered down CPU when cpudl_find sees itsfree_cpus bit is set. If this happens the task will not have theopportunity to run.One example is outlined here:https://lore.kernel.org/lkml/20250110233010.2339521-1-opendmb@gmail.comAnother occurs when the last deadline task is migrated from aCPU that has an offlined runqueue. The dequeue_task member ofthe deadline scheduler class will eventually call cpudl_clearand set the free_cpus bit for the CPU.This commit modifies the cpudl_clear function to be aware of theonline state of the deadline runqueue so that the free_cpus maskcan be updated appropriately.It is no longer necessary to manage the mask outside of thecpudl_set/clear functions so the cpudl_set/clear_freecpufunctions are removed. In addition, since the free_cpus mask isnow only updated under the cpudl lock the code was changed touse the non-atomic __cpumask functions.

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-mixer: us16x08: validate meter packet indicesget_meter_levels_from_urb() parses the 64-byte meter packets sent bythe device and fills the per-channel arrays meter_level[],comp_level[] and master_level[] in struct snd_us16x08_meter_store.Currently the function derives the channel index directly from themeter packet (MUB2(meter_urb, s) - 1) and uses it to index thosearrays without validating the range. If the packet contains anegative or out-of-range channel number, the driver may write pastthe end of these arrays.Introduce a local channel variable and validate it before updating thearrays. We reject negative indices, limit meter_level[] andcomp_level[] to SND_US16X08_MAX_CHANNELS, and guard master_level[]updates with ARRAY_SIZE(master_level).

However, the functionunconditionally executes readb(apbs[IndexCard].RamIO + VERS) at theend.If cmd is 6, IndexCard may reference a board that does not exist(where RamIO is NULL), leading to a NULL pointer dereference.Fix this by skipping the readb access when cmd is 6, as thiscommand is a global information query and does not target a specificboard context.

CVE-2025-68808 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:media: vidtv: initialize local pointers upon transfer of memory ownershipvidtv_channel_si_init() creates a temporary list (program, service, event)and ownership of the memory itself is transferred to the PAT/SDT/EITtables through vidtv_psi_pat_program_assign(),vidtv_psi_sdt_service_assign(), vidtv_psi_eit_event_assign().The problem here is that the local pointer where the memory ownershiptransfer was completed is not initialized to NULL. This causes thevidtv_psi_pmt_create_sec_for_each_pat_entry() function to fail, andin the flow that jumps to free_eit, the memory that was freed byvidtv_psi_*_table_destroy() can be accessed again byvidtv_psi_*_event_destroy() due to the uninitialized local pointer, so itis freed once again.Therefore, to prevent use-after-free and double-free vulnerability,local pointers must be initialized to NULL when transferring memoryownership.

CVE-2025-68814 Severity: Moderate CVSS3 score: 5.5

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.

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

Description: In the Linux kernel, the following vulnerability has been resolved:powerpc/64s/slb: Fix SLB multihit issue during SLB preloadOn systems using the hash MMU, there is a software SLB preload cache thatmirrors the entries loaded into the hardware SLB buffer. This preloadcache is subject to periodic eviction - typically after every 256 contextswitches - to remove old entry.To optimize performance, the kernel skips switch_mmu_context() inswitch_mm_irqs_off() when the prev and next mm_struct are the same.However, on hash MMU systems, this can lead to inconsistencies betweenthe hardware SLB and the software preload cache.If an SLB entry for a process is evicted from the software cache on oneCPU, and the same process later runs on another CPU without executingswitch_mmu_context(), the hardware SLB may retain stale entries. If thekernel then attempts to reload that entry, it can trigger an SLBmulti-hit error.The following timeline shows how stale SLB entries are created and cancause a multi-hit error when a process moves between CPUs without aMMU context switch.CPU 0 CPU 1----- -----Process Pexec swapper/1 load_elf_binary begin_new_exc activate_mm switch_mm_irqs_off switch_mmu_context switch_slb /* * This invalidates all * the entries in the HW * and setup the new HW * SLB entries as per the * preload cache. */context_switchsched_migrate_task migrates process P to cpu-1Process swapper/0 context switch (to process P)(uses mm_struct of Process P) switch_mm_irqs_off() switch_slb load_slb++ /* * load_slb becomes 0 here * and we evict an entry from * the preload cache with * preload_age().

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

CVE-2025-71130 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:dm-verity: disable recursive forward error correctionThere are two problems with the recursive correction:1. It may cause denial-of-service. In fec_read_bufs, there is a loop thathas 253 iterations. For each iteration, we may call verity_hash_for_blockrecursively. There is a limit of 4 nested recursions - that means thatthere may be at most 253^4 (4 billion) iterations. Red Hat QE teamactually created an image that pushes dm-verity to this limit - and thisimage just makes the udev-worker process get stuck in the 'D' state.2. It doesn't work. In fec_read_bufs we store data into the variable"fio->bufs", but fio bufs is shared between recursive invocations, if"verity_hash_for_block" invoked correction recursively, it wouldoverwrite partially filled fio->bufs.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: always detect conflicting inodes when logging inode refsAfter rename exchanging (either with the rename exchange operation orregular renames in multiple non-atomic steps) two inodes and at leastone of them is a directory, we can end up with a log tree that containsonly of the inodes and after a power failure that can result in an attemptto delete the other inode when it should not because it was not deletedbefore the power failure. In some case that delete attempt fails whenthe target inode is a directory that contains a subvolume inside it, sincethe log replay code is not prepared to deal with directory entries thatpoint to root items (only inode items).1) We have directories "dir1" (inode A) and "dir2" (inode B) under the same parent directory;2) We have a file (inode C) under directory "dir1" (inode A);3) We have a subvolume inside directory "dir2" (inode B);4) All these inodes were persisted in a past transaction and we are currently at transaction N;5) We rename the file (inode C), so at btrfs_log_new_name() we update inode C's last_unlink_trans to N;6) We get a rename exchange for "dir1" (inode A) and "dir2" (inode B), so after the exchange "dir1" is inode B and "dir2" is inode A. During the rename exchange we call btrfs_log_new_name() for inodes A and B, but because they are directories, we don't update their last_unlink_trans to N;7) An fsync against the file (inode C) is done, and because its inode has a last_unlink_trans with a value of N we log its parent directory (inode A) (through btrfs_log_all_parents(), called from btrfs_log_inode_parent()).8) So we end up with inode B not logged, which now has the old name of inode A. At copy_inode_items_to_log(), when logging inode A, we did not check if we had any conflicting inode to log because inode A has a generation lower than the current transaction (created in a past transaction);9) After a power failure, when replaying the log tree, since we find that inode A has a new name that conflicts with the name of inode B in the fs tree, we attempt to delete inode B... this is wrong since that directory was never deleted before the power failure, and because there is a subvolume inside that directory, attempting to delete it will fail since replay_dir_deletes() and btrfs_unlink_inode() are not prepared to deal with dir items that point to roots instead of inodes. When that happens the mount fails and we get a stack trace like the following: [87.2314] BTRFS info (device dm-0): start tree-log replay [87.2318] BTRFS critical (device dm-0): failed to delete reference to subvol, root 5 inode 256 parent 259 [87.2332] ------------[ cut here ]------------ [87.2338] BTRFS: Transaction aborted (error -2) [87.2346] WARNING: CPU: 1 PID: 638968 at fs/btrfs/inode.c:4345 __btrfs_unlink_inode+0x416/0x440 [btrfs] [87.2368] Modules linked in: btrfs loop dm_thin_pool (...)

CVE-2025-71184 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix NULL dereference on root when tracing inode evictionWhen evicting an inode the first thing we do is to setup tracing for it,which implies fetching the root's id. But in btrfs_evict_inode() theroot might be NULL, as implied in the next check that we do inbtrfs_evict_inode().Hence, we either should set the ->root_objectid to 0 in case the root isNULL, or we move tracing setup after checking that the root is notNULL. Setting the rootid to 0 at least gives us the possibility to tracethis call even in the case when the root is NULL, so that's the solutiontaken here.

Since arg_map->size is updated to a non-zero value before memoryallocation, free_choose_arg_map() will iterate over arg_map->args anddereference a NULL pointer.To prevent this potential NULL pointer dereference and makefree_choose_arg_map() more resilient, add checks for pointers beforeiterating.

Description: In the Linux kernel, the following vulnerability has been resolved:nvme-tcp: fix NULL pointer dereferences in nvmet_tcp_build_pdu_iovecCommit efa56305908b ("nvmet-tcp: Fix a kernel panic when host sends an invalid H2C PDU length")added ttag bounds checking and data_offsetvalidation in nvmet_tcp_handle_h2c_data_pdu(), but it did not validatewhether the command's data structures (cmd->req.sg and cmd->iov) havebeen properly initialized before processing H2C_DATA PDUs.The nvmet_tcp_build_pdu_iovec() function dereferences these pointerswithout NULL checks. This can be triggered by sending H2C_DATA PDUimmediately after the ICREQ/ICRESP handshake, beforesending a CONNECT command or NVMe write command.Attack vectors that trigger NULL pointer dereferences:1. H2C_DATA PDU sent before CONNECT -> both pointers NULL2. H2C_DATA PDU for READ command -> cmd->req.sg allocated, cmd->iov NULL3. H2C_DATA PDU for uninitialized command slot -> both pointers NULLThe fix validates both cmd->req.sg and cmd->iov before callingnvmet_tcp_build_pdu_iovec(). Both checks are required because:- Uninitialized commands: both NULL- READ commands: cmd->req.sg allocated, cmd->iov NULL- WRITE commands: both allocated

CVE-2026-23047 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:libceph: make calc_target() set t->paused, not just clear itCurrently calc_target() clears t->paused if the request shouldn't bepaused anymore, but doesn't ever set t->paused even though it's able todetermine when the request should be paused. Setting t->paused is leftto __submit_request() which is fine for regular requests but doesn'twork for linger requests -- since __submit_request() doesn't operateon linger requests, there is nowhere for lreq->t.paused to be set.One consequence of this is that watches don't get reestablished onpaused -> unpaused transitions in cases where requests have been pausedlong enough for the (paused) unwatch request to time out and for thesubsequent (re)watch request to enter the paused state. On top of thewatch not getting reestablished, rbd_reregister_watch() gets stuck withrbd_dev->watch_mutex held: rbd_register_watch __rbd_register_watch ceph_osdc_watch linger_reg_commit_waitIt's waiting for lreq->reg_commit_wait to be completed, but for that tohappen the respective request needs to end up on need_resend_linger listand be kicked when requests are unpaused. There is no chance for thatif the request in question is never marked paused in the first place.The fact that rbd_dev->watch_mutex remains taken out forever thenprevents the image from getting unmapped -- "rbd unmap" would inevitablyhang in D state on an attempt to grab the mutex.

CVE-2026-23063 Severity: Moderate CVSS3 score: 5.5

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.

Description: In the Linux kernel, the following vulnerability has been resolved:regmap: Fix race condition in hwspinlock irqsave routinePreviously, the address of the shared member '&map->spinlock_flags' waspassed directly to 'hwspin_lock_timeout_irqsave'. This creates a racecondition where multiple contexts contending for the lock could overwritethe shared flags variable, potentially corrupting the state for thecurrent lock owner.Fix this by using a local stack variable 'flags' to store the IRQ statetemporarily.

Description: In the Linux kernel, the following vulnerability has been resolved:can: esd_usb: esd_usb_read_bulk_callback(): fix URB memory leakFix similar memory leak as in commit 7352e1d5932a ("can: gs_usb:gs_usb_receive_bulk_callback(): fix URB memory leak").In esd_usb_open(), the URBs for USB-in transfers are allocated, added tothe dev->rx_submitted anchor and submitted. In the complete callbackesd_usb_read_bulk_callback(), the URBs are processed and resubmitted. Inesd_usb_close() the URBs are freed by callingusb_kill_anchored_urbs(&dev->rx_submitted).However, this does not take into account that the USB framework unanchorsthe URB before the complete function is called. This means that once anin-URB has been completed, it is no longer anchored and is ultimately notreleased in esd_usb_close().Fix the memory leak by anchoring the URB in theesd_usb_read_bulk_callback() to the dev->rx_submitted anchor.

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

Description: In the Linux kernel, the following vulnerability has been resolved:irqchip/gic-v3-its: Avoid truncating memory addressesOn 32-bit machines with CONFIG_ARM_LPAE, it is possible for lowmemallocations to be backed by addresses physical memory above the 32-bitaddress limit, as found while experimenting with larger VMSPLITconfigurations.This caused the qemu virt model to crash in the GICv3 driver, whichallocates the 'itt' object using GFP_KERNEL. Since all memory belowthe 4GB physical address limit is in ZONE_DMA in this configuration,kmalloc() defaults to higher addresses for ZONE_NORMAL, and theITS driver stores the physical address in a 32-bit 'unsigned long'variable.Change the itt_addr variable to the correct phys_addr_t type instead,along with all other variables in this driver that hold a physicaladdress.The gicv5 driver correctly uses u64 variables, while all other irqchipdrivers don't call virt_to_phys or similar interfaces. It's expected thatother device drivers have similar issues, but fixing this one issufficient for booting a virtio based guest.

Description: In the Linux kernel, the following vulnerability has been resolved:ipvlan: Make the addrs_lock be per portMake the addrs_lock be per port, not per ipvlan dev.Initial code seems to be written in the assumption,that any address change must occur under RTNL.But it is not so for the case of IPv6. So1) Introduce per-port addrs_lock.2) It was needed to fix places where it was forgottento take lock (ipvlan_open/ipvlan_close)This appears to be a very minor problem though.Since it's highly unlikely that ipvlan_add_addr() willbe called on 2 CPU simultaneously. But nevertheless,this could cause:1) False-negative of ipvlan_addr_busy(): one interfaceiterated through all port->ipvlans + ipvlan->addrsunder some ipvlan spinlock, and another added IPunder its own lock. Though this is only possiblefor IPv6, since looks like only ipvlan_addr6_event() can becalled without rtnl_lock.2) Race since ipvlan_ht_addr_add(port) is called underdifferent ipvlan->addrs_lock locksThis should not affect performance, since add/remove IPis a rare situation and spinlock is not taken on fastpaths.

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.

In this case, thecommand sequence is currently:- SCTP_CMD_PEER_INIT- SCTP_CMD_TIMER_STOP (T1_INIT)- SCTP_CMD_TIMER_START (T1_COOKIE)- SCTP_CMD_NEW_STATE (COOKIE_ECHOED)- SCTP_CMD_ASSOC_SHKEY- SCTP_CMD_GEN_COOKIE_ECHOIf SCTP_CMD_ASSOC_SHKEY fails, asoc->shkey remains NULL, whileasoc->peer.auth_capable and asoc->peer.peer_chunks have already been set bySCTP_CMD_PEER_INIT. This allows a DATA chunk with auth = 1 and shkey = NULLto be queued by sctp_datamsg_from_user().Since command interpretation stops on failure, no COOKIE_ECHO should beensent via SCTP_CMD_GEN_COOKIE_ECHO. However, the T1_COOKIE timer has alreadybeen started, and it may enqueue a COOKIE_ECHO into the outqueue later. Asa result, the DATA chunk can be transmitted together with the COOKIE_ECHOin sctp_outq_flush_data(), leading to the observed issue.Similar to the other places where it calls sctp_auth_asoc_init_active_key()right after sctp_process_init(), this patch moves the SCTP_CMD_ASSOC_SHKEYimmediately after SCTP_CMD_PEER_INIT, before stopping T1_INIT and startingT1_COOKIE. This ensures that if shared key generation fails, authenticatedDATA cannot be sent. It also allows the T1_INIT timer to retransmit INIT,giving the client another chance to process INIT_ACK and retry key setup.

CVE-2026-23136 Severity: Moderate CVSS3 score: 5.5

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.

Description: In the Linux kernel, the following vulnerability has been resolved:tracing: Add recursion protection in kernel stack trace recordingA bug was reported about an infinite recursion caused by tracing the rcuevents with the kernel stack trace trigger enabled. The stack trace codecalled back into RCU which then called the stack trace again.Expand the ftrace recursion protection to add a set of bits to protectevents from recursion. Each bit represents the context that the event isin (normal, softirq, interrupt and NMI).Have the stack trace code use the interrupt context to protect againstrecursion.Note, the bug showed an issue in both the RCU code as well as the tracingstacktrace code. This only handles the tracing stack trace side of thebug. The RCU fix will be handled separately.

CVE-2026-23140 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.

Description: In the Linux kernel, the following vulnerability has been resolved:rocker: fix memory leak in rocker_world_port_post_fini()In rocker_world_port_pre_init(), rocker_port->wpriv is allocated withkzalloc(wops->port_priv_size, GFP_KERNEL). However, inrocker_world_port_post_fini(), the memory is only freed whenwops->port_post_fini callback is set: if (!wops->port_post_fini) return; wops->port_post_fini(rocker_port); kfree(rocker_port->wpriv);Since rocker_ofdpa_ops does not implement port_post_fini callback(it is NULL), the wpriv memory allocated for each port is never freedwhen ports are removed. This leads to a memory leak ofsizeof(struct ofdpa_port) bytes per port on every device removal.Fix this by always calling kfree(rocker_port->wpriv) regardless ofwhether the port_post_fini callback exists.

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

CVE-2026-23237 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:platform/x86: classmate-laptop: Add missing NULL pointer checksIn a few places in the Classmate laptop driver, code using the accelobject may run before that object's address is stored in the driverdata of the input device using it.For example, cmpc_accel_sensitivity_store_v4() is the "show" methodof cmpc_accel_sensitivity_attr_v4 which is added in cmpc_accel_add_v4(),before calling dev_set_drvdata() for inputdev->dev. If the sysfsattribute is accessed prematurely, the dev_get_drvdata(&inputdev->dev)call in in cmpc_accel_sensitivity_store_v4() returns NULL whichleads to a NULL pointer dereference going forward.Moreover, sysfs attributes using the input device are added beforeinitializing that device by cmpc_add_acpi_notify_device() and if oneof them is accessed before running that function, a NULL pointerdereference will occur.For example, cmpc_accel_sensitivity_attr_v4 is added before callingcmpc_add_acpi_notify_device() and if it is read prematurely, thedev_get_drvdata(&acpi->dev) call in cmpc_accel_sensitivity_show_v4()returns NULL which leads to a NULL pointer dereference going forward.Fix this by adding NULL pointer checks in all of the relevant places.

Description: In the Linux kernel, the following vulnerability has been resolved:media: dvb-core: fix wrong reinitialization of ringbuffer on reopendvb_dvr_open() calls dvb_ringbuffer_init() when a new reader opens theDVR device. dvb_ringbuffer_init() calls init_waitqueue_head(), whichreinitializes the waitqueue list head to empty.Since dmxdev->dvr_buffer.queue is a shared waitqueue (all opens of thesame DVR device share it), this orphans any existing waitqueue entriesfrom io_uring poll or epoll, leaving them with stale prev/next pointerswhile the list head is reset to {self, self}.The waitqueue and spinlock in dvr_buffer are already properlyinitialized once in dvb_dmxdev_init(). The open path only needs toreset the buffer data pointer, size, and read/write positions.Replace the dvb_ringbuffer_init() call in dvb_dvr_open() with directassignment of data/size and a call to dvb_ringbuffer_reset(), whichproperly resets pread, pwrite, and error with correct memory orderingwithout touching the waitqueue or spinlock.

CVE-2026-23343 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---

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. Add a check in __devm_cxl_add_nvdimm_bridge() to ensure that the cxl_nvb driver is attached during cxl_acpi_probe().3. Take the cxl_root uport_dev lock and the cxl_nvb->dev lock in devm_cxl_add_nvdimm() before checking nvdimm_bus is valid.4. 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.

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.

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

CVE-2026-31414 Severity: Moderate CVSS3 score: 5.5

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

CVE-2026-31420 Severity: Moderate CVSS3 score: 5.5

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.

Because NF_ARP_OUT == 1 == NF_INET_LOCAL_IN, the .hooksvalidation silently passes for the wrong reasons, allowing matches torun on ARP chains where the hook assumptions (e.g. state->in beingset on input hooks) do not hold.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: btusb: clamp SCO altsetting table indicesbtusb_work() maps the number of active SCO links to USB alternatesettings through a three-entry lookup table when CVSD traffic usestransparent voice settings. The lookup currently indexes alts[] withdata->sco_num - 1 without first constraining sco_num to the number ofavailable table entries.While the table only defines alternate settings for up to three SCOlinks, data->sco_num comes from hci_conn_num() and is used directly.Cap the lookup to the last table entry before indexing it so thedriver keeps selecting the highest supported alternate setting withoutreading past alts[].

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:net: bonding: fix NULL deref in bond_debug_rlb_hash_showrlb_clear_slave intentionally keeps RLB hash-table entries onthe rx_hashtbl_used_head list with slave set to NULL when noreplacement slave is available. However, bond_debug_rlb_hash_showvisites client_info->slave without checking if it's NULL.Other used-list iterators in bond_alb.c already handle this NULL-slavestate safely:- rlb_update_client returns early on !client_info->slave- rlb_req_update_slave_clients, rlb_clear_slave, and rlb_rebalancecompare slave values before visiting- lb_req_update_subnet_clients continues if slave is NULLThe following NULL deref crash can be trigger inbond_debug_rlb_hash_show:[ 1.289791] BUG: kernel NULL pointer dereference, address: 0000000000000000[ 1.292058] RIP: 0010:bond_debug_rlb_hash_show (drivers/net/bonding/bond_debugfs.c:41)[ 1.293101] RSP: 0018:ffffc900004a7d00 EFLAGS: 00010286[ 1.293333] RAX: 0000000000000000 RBX: ffff888102b48200 RCX: ffff888102b48204[ 1.293631] RDX: ffff888102b48200 RSI: ffffffff839daad5 RDI: ffff888102815078[ 1.293924] RBP: ffff888102815078 R08: ffff888102b4820e R09: 0000000000000000[ 1.294267] R10: 0000000000000000 R11: 0000000000000000 R12: ffff888100f929c0[ 1.294564] R13: ffff888100f92a00 R14: 0000000000000001 R15: ffffc900004a7ed8[ 1.294864] FS: 0000000001395380(0000) GS:ffff888196e75000(0000) knlGS:0000000000000000[ 1.295239] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 1.295480] CR2: 0000000000000000 CR3: 0000000102adc004 CR4: 0000000000772ef0[ 1.295897] Call Trace:[ 1.296134] seq_read_iter (fs/seq_file.c:231)[ 1.296341] seq_read (fs/seq_file.c:164)[ 1.296493] full_proxy_read (fs/debugfs/file.c:378 (discriminator 1))[ 1.296658] vfs_read (fs/read_write.c:572)[ 1.296981] ksys_read (fs/read_write.c:717)[ 1.297132] do_syscall_64 (arch/x86/entry/syscall_64.c:63 (discriminator 1) arch/x86/entry/syscall_64.c:94 (discriminator 1))[ 1.297325] entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:130)Add a NULL check and print "(none)" for entries with no assigned slave.

CVE-2026-31548 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: cfg80211: cancel pmsr_free_wk in cfg80211_pmsr_wdev_downWhen the nl80211 socket that originated a PMSR request isclosed, cfg80211_release_pmsr() sets the request's nl_portidto zero and schedules pmsr_free_wk to process the abortasynchronously. If the interface is concurrently torn downbefore that work runs, cfg80211_pmsr_wdev_down() callscfg80211_pmsr_process_abort() directly. However, the already-scheduled pmsr_free_wk work item remains pending and may runafter the interface has been removed from the driver. Thiscould cause the driver's abort_pmsr callback to operate on atorn-down interface, leading to undefined behavior andpotential crashes.Cancel pmsr_free_wk synchronously in cfg80211_pmsr_wdev_down()before calling cfg80211_pmsr_process_abort(). This ensures anypending or in-progress work is drained before interface teardownproceeds, preventing the work from invoking the driver abortcallback after the interface is gone.

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.

However, file descriptors that arealready open do not go away immediately: they remain valid until the lastreference is dropped and the driver's .release() is invoked.In as102, as102_usb_probe() calls usb_register_dev() and then, on anerror path, does usb_deregister_dev() and frees as102_dev_t right away.If userspace raced a successful open() before the deregistration, thatopen FD will later hit as102_release() --> as102_usb_release() and accessor free as102_dev_t again, occur a race to use-after-free anddouble-free vuln.The fix is to never kfree(as102_dev_t) directly once usb_register_dev()has succeeded. After deregistration, defer freeing memory to .release().In other words, let release() perform the last kfree when the final openFD is closed.

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.

CVE-2026-31630 Severity: Moderate CVSS3 score: 5.5

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.

The current code consumes bytes into recv_skb and may already handa complete frame to pn533_recv_frame() before allocating a fresh receivebuffer.If that alloc_skb() fails, the callback returns 0 even though it hasalready consumed bytes, and it leaves recv_skb as NULL for the nextreceive callback. That breaks the receive_buf() accounting contract andcan also lead to a NULL dereference on the next skb_put_u8().Allocate the receive skb lazily before consuming the next byte instead.If allocation fails, return the number of bytes already accepted.

Description: In the Linux kernel, the following vulnerability has been resolved:f2fs: fix UAF caused by decrementing sbi->nr_pages[] in f2fs_write_end_io()The xfstests case "generic/107" and syzbot have both reported a NULLpointer dereference.The concurrent scenario that triggers the panic is as follows:F2FS_WB_CP_DATA write callback umount - f2fs_write_checkpoint - f2fs_wait_on_all_pages(sbi, F2FS_WB_CP_DATA)- blk_mq_end_request - bio_endio - f2fs_write_end_io : dec_page_count(sbi, F2FS_WB_CP_DATA) : wake_up(&sbi->cp_wait) - kill_f2fs_super - kill_block_super - f2fs_put_super : iput(sbi->node_inode) : sbi->node_inode = NULL : f2fs_in_warm_node_list - is_node_folio // sbi->node_inode is NULL and panicThe root cause is that f2fs_put_super() calls iput(sbi->node_inode) andsets sbi->node_inode to NULL after sbi->nr_pages[F2FS_WB_CP_DATA] isdecremented to zero. As a result, f2fs_in_warm_node_list() maydereference a NULL node_inode when checking whether a folio belongs tothe node inode, leading to a panic.This patch fixes the issue by calling f2fs_in_warm_node_list() beforedecrementing sbi->nr_pages[F2FS_WB_CP_DATA], thus preventing theuse-after-free condition.

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.

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.

CVE-2026-43009 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix incorrect pruning due to atomic fetch precision trackingWhen backtrack_insn encounters a BPF_STX instruction with BPF_ATOMICand BPF_FETCH, the src register (or r0 for BPF_CMPXCHG) also acts asa destination, thus receiving the old value from the memory location.The current backtracking logic does not account for this. It treatsatomic fetch operations the same as regular stores where the srcregister is only an input. This leads the backtrack_insn to fail topropagate precision to the stack location, which is then not markedas precise!Later, the verifier's path pruning can incorrectly consider two statesequivalent when they differ in terms of stack state. Meaning, twobranches can be treated as equivalent and thus get pruned when theyshould not be seen as such.Fix it as follows: Extend the BPF_LDX handling in backtrack_insn toalso cover atomic fetch operations via is_atomic_fetch_insn() helper.When the fetch dst register is being tracked for precision, clear it,and propagate precision over to the stack slot. For non-stack memory,the precision walk stops at the atomic instruction, same as regularBPF_LDX. This covers all fetch variants.Before: 0: (b7) r1 = 8 ; R1=8 1: (7b) *(u64 *)(r10 -8) = r1 ; R1=8 R10=fp0 fp-8=8 2: (b7) r2 = 0 ; R2=0 3: (db) r2 = atomic64_fetch_add((u64 *)(r10 -8), r2) ; R2=8 R10=fp0 fp-8=mmmmmmmm 4: (bf) r3 = r10 ; R3=fp0 R10=fp0 5: (0f) r3 += r2 mark_precise: frame0: last_idx 5 first_idx 0 subseq_idx -1 mark_precise: frame0: regs=r2 stack= before 4: (bf) r3 = r10 mark_precise: frame0: regs=r2 stack= before 3: (db) r2 = atomic64_fetch_add((u64 *)(r10 -8), r2) mark_precise: frame0: regs=r2 stack= before 2: (b7) r2 = 0 6: R2=8 R3=fp8 6: (b7) r0 = 0 ; R0=0 7: (95) exitAfter: 0: (b7) r1 = 8 ; R1=8 1: (7b) *(u64 *)(r10 -8) = r1 ; R1=8 R10=fp0 fp-8=8 2: (b7) r2 = 0 ; R2=0 3: (db) r2 = atomic64_fetch_add((u64 *)(r10 -8), r2) ; R2=8 R10=fp0 fp-8=mmmmmmmm 4: (bf) r3 = r10 ; R3=fp0 R10=fp0 5: (0f) r3 += r2 mark_precise: frame0: last_idx 5 first_idx 0 subseq_idx -1 mark_precise: frame0: regs=r2 stack= before 4: (bf) r3 = r10 mark_precise: frame0: regs=r2 stack= before 3: (db) r2 = atomic64_fetch_add((u64 *)(r10 -8), r2) mark_precise: frame0: regs= stack=-8 before 2: (b7) r2 = 0 mark_precise: frame0: regs= stack=-8 before 1: (7b) *(u64 *)(r10 -8) = r1 mark_precise: frame0: regs=r1 stack= before 0: (b7) r1 = 8 6: R2=8 R3=fp8 6: (b7) r0 = 0 ; R0=0 7: (95) exit

Every other SCSI LLD (virtio_scsi, mpt3sas, ipr, scsi_debug,mpi3mr) enforces this by draining or completing outstanding commands beforereturning SUCCESS.Because tcm_loop_target_reset() doesn't drain, the SCSI EH reuses in-flightscsi_cmnd structures for recovery commands (e.g. TUR) while the target corestill has async completion work queued for the old se_cmd.

CVE-2025-48964 Severity: Moderate CVSS3 score: 5.4

Description: ping in iputils before 20250602 allows a denial of service (application error in adaptive ping mode or incorrect data collection) via a crafted ICMP Echo Reply packet, because a zero timestamp can lead to large intermediate values that have an integer overflow when squared during statistics calculations. NOTE: this issue exists because of an incomplete fix for CVE-2025-47268 (that fix was only about timestamp calculations, and it did not account for a specific scenario where the original timestamp in the ICMP payload is zero).

CVE-2026-23076 Severity: Moderate CVSS3 score: 5.4

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: ctxfi: Fix potential OOB access in audio mixer handlingIn the audio mixer handling code of ctxfi driver, the conf field isused as a kind of loop index, and it's referred in the index callbacks(amixer_index() and sum_index()).As spotted recently by fuzzers, the current code causes OOB access atthose functions.| UBSAN: array-index-out-of-bounds in /build/reproducible-path/linux-6.17.8/sound/pci/ctxfi/ctamixer.c:347:48| index 8 is out of range for type 'unsigned char [8]'After the analysis, the cause was found to be the lack of the proper(re-)initialization of conj field.This patch addresses those OOB accesses by adding the properinitializations of the loop indices.

CVE-2022-50554 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:blk-mq: avoid double ->queue_rq() because of early timeoutDavid Jeffery found one double ->queue_rq() issue, so far it canbe triggered in VM use case because of long vmexit latency or preemptlatency of vCPU pthread or long page fault in vCPU pthread, then blockIO req could be timed out before queuing the request to hardware but aftercalling blk_mq_start_request() during ->queue_rq(), then timeout handlermay handle it by requeue, then double ->queue_rq() is caused, and kernelpanic.So far, it is driver's responsibility to cover the race between timeoutand completion, so it seems supposed to be solved in driver in theory,given driver has enough knowledge.But it is really one common problem, lots of driver could have similarissue, and could be hard to fix all affected drivers, even it isn't easyfor driver to handle the race. So David suggests this patch by drainingin-progress ->queue_rq() for solving this issue.

CVE-2023-53728 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:posix-timers: Ensure timer ID search-loop limit is validposix_timer_add() tries to allocate a posix timer ID by starting from thecached ID which was stored by the last successful allocation.This is done in a loop searching the ID space for a free slot one byone. The loop has to terminate when the search wrapped around to thestarting point.But that's racy vs. establishing the starting point. That is read outlockless, which leads to the following problem:CPU0 CPU1posix_timer_add() start = sig->posix_timer_id; lock(hash_lock); ... posix_timer_add() if (++sig->posix_timer_id < 0) start = sig->posix_timer_id; sig->posix_timer_id = 0;So CPU1 can observe a negative start value, i.e. -1, and the loop breaknever happens because the condition can never be true: if (sig->posix_timer_id == start) break;While this is unlikely to ever turn into an endless loop as the ID space ishuge (INT_MAX), the racy read of the start value caught the attention ofKCSAN and Dmitry unearthed that incorrectness.Rewrite it so that all id operations are under the hash lock.

CVE-2025-22058 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:udp: Fix memory accounting leak.Matt Dowling reported a weird UDP memory usage issue.Under normal operation, the UDP memory usage reported in /proc/net/sockstatremains close to zero. However, it occasionally spiked to 524,288 pagesand never dropped. Moreover, the value doubled when the application wasterminated. Finally, it caused intermittent packet drops.We can reproduce the issue with the script below [0]: 1. /proc/net/sockstat reports 0 pages # cat /proc/net/sockstat | grep UDP: UDP: inuse 1 mem 0 2. Run the script till the report reaches 524,288 # python3 test.py & sleep 5 # cat /proc/net/sockstat | grep UDP: UDP: inuse 3 mem 524288 <-- (INT_MAX + 1) >> PAGE_SHIFT 3. Kill the socket and confirm the number never drops # pkill python3 && sleep 5 # cat /proc/net/sockstat | grep UDP: UDP: inuse 1 mem 524288 4. (necessary since v6.0) Trigger proto_memory_pcpu_drain() # python3 test.py & sleep 1 && pkill python3 5. The number doubles # cat /proc/net/sockstat | grep UDP: UDP: inuse 1 mem 1048577The application set INT_MAX to SO_RCVBUF, which triggered an integeroverflow in udp_rmem_release().When a socket is close()d, udp_destruct_common() purges its receivequeue and sums up skb->truesize in the queue. This total is calculatedand stored in a local unsigned integer variable.The total size is then passed to udp_rmem_release() to adjust memoryaccounting. However, because the function takes a signed integerargument, the total size can wrap around, causing an overflow.Then, the released amount is calculated as follows: 1) Add size to sk->sk_forward_alloc. 2) Round down sk->sk_forward_alloc to the nearest lower multiple of PAGE_SIZE and assign it to amount. 3) Subtract amount from sk->sk_forward_alloc. 4) Pass amount >> PAGE_SHIFT to __sk_mem_reduce_allocated().When the issue occurred, the total in udp_destruct_common() was 2147484480(INT_MAX + 833), which was cast to -2147482816 in udp_rmem_release().At 1) sk->sk_forward_alloc is changed from 3264 to -2147479552, and2) sets -2147479552 to amount. 3) reverts the wraparound, so we don'tsee a warning in inet_sock_destruct(). However, udp_memory_allocatedends up doubling at 4).Since commit 3cd3399dd7a8 ("net: implement per-cpu reserves formemory_allocated"), memory usage no longer doubles immediately aftera socket is close()d because __sk_mem_reduce_allocated() caches theamount in udp_memory_per_cpu_fw_alloc. However, the next time a UDPsocket receives a packet, the subtraction takes effect, causing UDPmemory usage to double.This issue makes further memory allocation fail once the socket'ssk->sk_rmem_alloc exceeds net.ipv4.udp_rmem_min, resulting in packetdrops.To prevent this issue, let's use unsigned int for the calculation andcall sk_forward_alloc_add() only once for the small delta.Note that first_packet_length() also potentially has the same problem.[0]:from socket import *SO_RCVBUFFORCE = 33INT_MAX = (2 ** 31) - 1s = socket(AF_INET, SOCK_DGRAM)s.bind(('', 0))s.setsockopt(SOL_SOCKET, SO_RCVBUFFORCE, INT_MAX)c = socket(AF_INET, SOCK_DGRAM)c.connect(s.getsockname())data = b'a' * 100while True: c.send(data)

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

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

CVE-2025-38097 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:espintcp: remove encap socket caching to avoid reference leakThe current scheme for caching the encap socket can lead to referenceleaks when we try to delete the netns.The reference chain is: xfrm_state -> enacp_sk -> netnsSince the encap socket is a userspace socket, it holds a reference onthe netns. If we delete the espintcp state (through flush orindividual delete) before removing the netns, the reference on thesocket is dropped and the netns is correctly deleted. Otherwise, thenetns may not be reachable anymore (if all processes within the nshave terminated), so we cannot delete the xfrm state to drop itsreference on the socket.This patch results in a small (~2% in my tests) performanceregression.A GC-type mechanism could be added for the socket cache, to clearreferences if the state hasn't been used "recently", but it's a lotmore complex than just not caching the socket.

CVE-2025-38478 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: Fix initialization of data for instructions that write to subdeviceSome Comedi subdevice instruction handlers are known to accessinstruction data elements beyond the first `insn->n` elements in somecases. The `do_insn_ioctl()` and `do_insnlist_ioctl()` functionsallocate at least `MIN_SAMPLES` (16) data elements to deal with this,but they do not initialize all of that. For Comedi instruction codesthat write to the subdevice, the first `insn->n` data elements arecopied from user-space, but the remaining elements are leftuninitialized. That could be a problem if the subdevice instructionhandler reads the uninitialized data. Ensure that the first`MIN_SAMPLES` elements are initialized before calling these instructionhandlers, filling the uncopied elements with 0. For`do_insnlist_ioctl()`, the same data buffer elements are used forhandling a list of instructions, so ensure the first `MIN_SAMPLES`elements are initialized for each instruction that writes to thesubdevice.

CVE-2025-38480 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: Fix use of uninitialized data in insn_rw_emulate_bits()For Comedi `INSN_READ` and `INSN_WRITE` instructions on "digital"subdevices (subdevice types `COMEDI_SUBD_DI`, `COMEDI_SUBD_DO`, and`COMEDI_SUBD_DIO`), it is common for the subdevice driver not to have`insn_read` and `insn_write` handler functions, but to have an`insn_bits` handler function for handling Comedi `INSN_BITS`instructions. In that case, the subdevice's `insn_read` and/or`insn_write` function handler pointers are set to point to the`insn_rw_emulate_bits()` function by `__comedi_device_postconfig()`.For `INSN_WRITE`, `insn_rw_emulate_bits()` currently assumes that thesupplied `data[0]` value is a valid copy from user memory. It will atleast exist because `do_insnlist_ioctl()` and `do_insn_ioctl()` in"comedi_fops.c" ensure at lease `MIN_SAMPLES` (16) elements areallocated. However, if `insn->n` is 0 (which is allowable for`INSN_READ` and `INSN_WRITE` instructions, then `data[0]` may containuninitialized data, and certainly contains invalid data, possibly from adifferent instruction in the array of instructions handled by`do_insnlist_ioctl()`. This will result in an incorrect value beingwritten to the digital output channel (or to the digital input/outputchannel if configured as an output), and may be reflected in theinternal saved state of the channel.Fix it by returning 0 early if `insn->n` is 0, before reaching the codethat accesses `data[0]`. Previously, the function always returned 1 onsuccess, but it is supposed to be the number of data samples actuallyread or written up to `insn->n`, which is 0 in this case.

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: das16m1: Fix bit shift out of boundsWhen checking for a supported IRQ number, the following test is used: /* only irqs 2, 3, 4, 5, 6, 7, 10, 11, 12, 14, and 15 are valid */ if ((1 << it->options[1]) & 0xdcfc) {However, `it->options[i]` is an unchecked `int` value from userspace, sothe shift amount could be negative or out of bounds. Fix the test byrequiring `it->options[1]` to be within bounds before proceeding withthe original test.

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: fix use-after-free in cifs_oplock_breakA race condition can occur in cifs_oplock_break() leading to ause-after-free of the cinode structure when unmounting: cifs_oplock_break() _cifsFileInfo_put(cfile) cifsFileInfo_put_final() cifs_sb_deactive() [last ref, start releasing sb] kill_sb() kill_anon_super() generic_shutdown_super() evict_inodes() dispose_list() evict() destroy_inode() call_rcu(&inode->i_rcu, i_callback) spin_lock(&cinode->open_file_lock) <- OK [later] i_callback() cifs_free_inode() kmem_cache_free(cinode) spin_unlock(&cinode->open_file_lock) <- UAF cifs_done_oplock_break(cinode) <- UAFThe issue occurs when umount has already released its reference to thesuperblock. When _cifsFileInfo_put() calls cifs_sb_deactive(), thisreleases the last reference, triggering the immediate cleanup of allinodes under RCU. However, cifs_oplock_break() continues to access thecinode after this point, resulting in use-after-free.Fix this by holding an extra reference to the superblock during theentire oplock break operation. This ensures that the superblock andits inodes remain valid until the oplock break completes.

CVE-2025-39788 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: ufs: exynos: Fix programming of HCI_UTRL_NEXUS_TYPEOn Google gs101, the number of UTP transfer request slots (nutrs) is 32,and in this case the driver ends up programming the UTRL_NEXUS_TYPEincorrectly as 0.This is because the left hand side of the shift is 1, which is of typeint, i.e. 31 bits wide. Shifting by more than that width results inundefined behaviour.Fix this by switching to the BIT() macro, which applies correct typecasting as required. This ensures the correct value is written toUTRL_NEXUS_TYPE (0xffffffff on gs101), and it also fixes a UBSAN shiftwarning: UBSAN: shift-out-of-bounds in drivers/ufs/host/ufs-exynos.c:1113:21 shift exponent 32 is too large for 32-bit type 'int'For consistency, apply the same change to the nutmrs / UTMRL_NEXUS_TYPEwrite.

CVE-2025-39927 Severity: Moderate CVSS3 score: 5.3

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. ]

CVE-2025-40003 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:net: mscc: ocelot: Fix use-after-free caused by cyclic delayed workThe origin code calls cancel_delayed_work() in ocelot_stats_deinit()to cancel the cyclic delayed work item ocelot->stats_work. However,cancel_delayed_work() may fail to cancel the work item if it is alreadyexecuting. While destroy_workqueue() does wait for all pending work itemsin the work queue to complete before destroying the work queue, it cannotprevent the delayed work item from being rescheduled within theocelot_check_stats_work() function. This limitation exists because thedelayed work item is only enqueued into the work queue after its timerexpires. Before the timer expiration, destroy_workqueue() has no visibilityof this pending work item. Once the work queue appears empty,destroy_workqueue() proceeds with destruction. When the timer eventuallyexpires, the delayed work item gets queued again, leading to the followingwarning:workqueue: cannot queue ocelot_check_stats_work on wq ocelot-switch-statsWARNING: CPU: 2 PID: 0 at kernel/workqueue.c:2255 __queue_work+0x875/0xaf0...RIP: 0010:__queue_work+0x875/0xaf0...RSP: 0018:ffff88806d108b10 EFLAGS: 00010086RAX: 0000000000000000 RBX: 0000000000000101 RCX: 0000000000000027RDX: 0000000000000027 RSI: 0000000000000004 RDI: ffff88806d123e88RBP: ffffffff813c3170 R08: 0000000000000000 R09: ffffed100da247d2R10: ffffed100da247d1 R11: ffff88806d123e8b R12: ffff88800c00f000R13: ffff88800d7285c0 R14: ffff88806d0a5580 R15: ffff88800d7285a0FS: 0000000000000000(0000) GS:ffff8880e5725000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007fe18e45ea10 CR3: 0000000005e6c000 CR4: 00000000000006f0Call Trace: ? kasan_report+0xc6/0xf0 ? __pfx_delayed_work_timer_fn+0x10/0x10 ? __pfx_delayed_work_timer_fn+0x10/0x10 call_timer_fn+0x25/0x1c0 __run_timer_base.part.0+0x3be/0x8c0 ? __pfx_delayed_work_timer_fn+0x10/0x10 ? rcu_sched_clock_irq+0xb06/0x27d0 ? __pfx___run_timer_base.part.0+0x10/0x10 ? try_to_wake_up+0xb15/0x1960 ? _raw_spin_lock_irq+0x80/0xe0 ? __pfx__raw_spin_lock_irq+0x10/0x10 tmigr_handle_remote_up+0x603/0x7e0 ? __pfx_tmigr_handle_remote_up+0x10/0x10 ? sched_balance_trigger+0x1c0/0x9f0 ? sched_tick+0x221/0x5a0 ? _raw_spin_lock_irq+0x80/0xe0 ? __pfx__raw_spin_lock_irq+0x10/0x10 ? tick_nohz_handler+0x339/0x440 ? __pfx_tmigr_handle_remote_up+0x10/0x10 __walk_groups.isra.0+0x42/0x150 tmigr_handle_remote+0x1f4/0x2e0 ? __pfx_tmigr_handle_remote+0x10/0x10 ? ktime_get+0x60/0x140 ? lapic_next_event+0x11/0x20 ? clockevents_program_event+0x1d4/0x2a0 ? hrtimer_interrupt+0x322/0x780 handle_softirqs+0x16a/0x550 irq_exit_rcu+0xaf/0xe0 sysvec_apic_timer_interrupt+0x70/0x80 ...The following diagram reveals the cause of the above warning:CPU 0 (remove) | CPU 1 (delayed work callback)mscc_ocelot_remove() | ocelot_deinit() | ocelot_check_stats_work() ocelot_stats_deinit() | cancel_delayed_work()| ... | queue_delayed_work() destroy_workqueue() | (wait a time) | __queue_work() //UAFThe above scenario actually constitutes a UAF vulnerability.The ocelot_stats_deinit() is only invoked when initializationfailure or resource destruction, so we must ensure that anydelayed work items cannot be rescheduled.Replace cancel_delayed_work() with disable_delayed_work_sync()to guarantee proper cancellation of the delayed work item andensure completion of any currently executing work before theworkqueue is deallocated.A deadlock concern was considered: ocelot_stats_deinit() is calledin a process context and is not holding any locks that the delayedwork item might also need.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix metadata_dst leak __bpf_redirect_neigh_v{4,6}Cilium has a BPF egress gateway feature which forces outgoing K8s Podtraffic to pass through dedicated egress gateways which then SNAT thetraffic in order to interact with stable IPs outside the cluster.The traffic is directed to the gateway via vxlan tunnel in collect mdmode. A recent BPF change utilized the bpf_redirect_neigh() helper toforward packets after the arrival and decap on vxlan, which turned outover time that the kmalloc-256 slab usage in kernel was ever-increasing.The issue was that vxlan allocates the metadata_dst object and attachesit through a fake dst entry to the skb. The latter was never releasedthough given bpf_redirect_neigh() was merely setting the new dst entryvia skb_dst_set() without dropping an existing one first.

Description: urllib3 is a user-friendly HTTP client library for Python. Prior to 2.5.0, it is possible to disable redirects for all requests by instantiating a PoolManager and specifying retries in a way that disable redirects. By default, requests and botocore users are not affected. An application attempting to mitigate SSRF or open redirect vulnerabilities by disabling redirects at the PoolManager level will remain vulnerable. This issue has been patched in version 2.5.0.

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-2025-71182 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:can: j1939: make j1939_session_activate() fail if device is no longer registeredsyzbot is still reporting unregister_netdevice: waiting for vcan0 to become free. Usage count = 2even after commit 93a27b5891b8 ("can: j1939: add missing calls inNETDEV_UNREGISTER notification handler") was added. A debug printk() patchfound that j1939_session_activate() can succeed even afterj1939_cancel_active_session() from j1939_netdev_notify(NETDEV_UNREGISTER)has completed.Since j1939_cancel_active_session() is processed with the session list lockheld, checking ndev->reg_state in j1939_session_activate() with the sessionlist lock held can reliably close the race window.

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-2026-0992 Severity: Moderate CVSS3 score: 5.3

Description: A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to redundantly traverse catalog chains. This leads to excessive CPU consumption and degrades application availability, resulting in a denial-of-service condition.

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().

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.

After somedebugging I found out that the queues, which f_hid registers viapoll_wait were the problem. These were initialized usinginit_waitqueue_head inside hidg_bind. So effectively, the bind functionre-initialized the queues while there were still items in them.The solution is to move the initialization from hidg_bind to hidg_allocto extend their lifetimes to the lifetime of the function instance.Additionally, I found many other possibly problematic init calls in thebind function, which I moved as well.

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

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

Description: 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.

The steps of the issue is as follows:1) use getdent to traverse dir /proc/pid/net/dev_snmp6/, and current pde is tun3;2) in the [time windows] unregister netdevice tun3 and tun2, and erase them from rbtree. erase tun3 first, and then erase tun2. the pde(tun2) will be released to slab;3) continue to getdent process, then pde_subdir_next() will return pde(tun2) which is released, it will case uaf access.CPU 0 | CPU 1-------------------------------------------------------------------------traverse dir /proc/pid/net/dev_snmp6/ | unregister_netdevice(tun->dev) //tun3 tun2sys_getdents64() | iterate_dir() | proc_readdir() | proc_readdir_de() | snmp6_unregister_dev() pde_get(de); | proc_remove() read_unlock(&proc_subdir_lock); | remove_proc_subtree() | write_lock(&proc_subdir_lock); [time window] | rb_erase(&root->subdir_node, &parent->subdir); | write_unlock(&proc_subdir_lock); read_lock(&proc_subdir_lock); | next = pde_subdir_next(de); | pde_put(de); | de = next; //UAF |rbtree of dev_snmp6 | pde(tun3) / \ NULL pde(tun2)

CVE-2023-53756 Severity: Moderate CVSS3 score: 5.1

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: VMX: Fix crash due to uninitialized current_vmcsKVM enables 'Enlightened VMCS' and 'Enlightened MSR Bitmap' when running asa nested hypervisor on top of Hyper-V. When MSR bitmap is updated,evmcs_touch_msr_bitmap function uses current_vmcs per-cpu variable to markthat the msr bitmap was changed.vmx_vcpu_create() modifies the msr bitmap via vmx_disable_intercept_for_msr-> vmx_msr_bitmap_l01_changed which in the end calls this function. Thefunction checks for current_vmcs if it is null but the check isinsufficient because current_vmcs is not initialized. Because of this, thecode might incorrectly write to the structure pointed by current_vmcs valueleft by another task. Preemption is not disabled, the current task can bepreempted and moved to another CPU while current_vmcs is accessed multipletimes from evmcs_touch_msr_bitmap() which leads to crash.The manipulation of MSR bitmaps by callers happens only for vmcs01 so thesolution is to use vmx->vmcs01.vmcs instead of current_vmcs.

CVE-2024-56770 Severity: Moderate CVSS3 score: 5.1

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: netem: account for backlog updates from child qdiscIn general, 'qlen' of any classful qdisc should keep track of thenumber of packets that the qdisc itself and all of its children holds.In case of netem, 'qlen' only accounts for the packets in its internaltfifo. When netem is used with a child qdisc, the child qdisc can use'qdisc_tree_reduce_backlog' to inform its parent, netem, about createdor dropped SKBs. This function updates 'qlen' and the backlog statisticsof netem, but netem does not account for changes made by a child qdisc.'qlen' then indicates the wrong number of packets in the tfifo.If a child qdisc creates new SKBs during enqueue and informs its parentabout this, netem's 'qlen' value is increased. When netem dequeues thenewly created SKBs from the child, the 'qlen' in netem is not updated.If 'qlen' reaches the configured sch->limit, the enqueue function stopsworking, even though the tfifo is not full.Reproduce the bug:Ensure that the sender machine has GSO enabled. Configure netem as rootqdisc and tbf as its child on the outgoing interface of the machineas follows:$ tc qdisc add dev root handle 1: netem delay 100ms limit 100$ tc qdisc add dev parent 1:0 tbf rate 50Mbit burst 1542 latency 50msSend bulk TCP traffic out via this interface, e.g., by running an iPerf3client on the machine. Check the qdisc statistics:$ tc -s qdisc show dev Statistics after 10s of iPerf3 TCP test before the fix (note thatnetem's backlog > limit, netem stopped accepting packets):qdisc netem 1: root refcnt 2 limit 1000 delay 100ms Sent 2767766 bytes 1848 pkt (dropped 652, overlimits 0 requeues 0) backlog 4294528236b 1155p requeues 0qdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms Sent 2767766 bytes 1848 pkt (dropped 327, overlimits 7601 requeues 0) backlog 0b 0p requeues 0Statistics after the fix:qdisc netem 1: root refcnt 2 limit 1000 delay 100ms Sent 37766372 bytes 24974 pkt (dropped 9, overlimits 0 requeues 0) backlog 0b 0p requeues 0qdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms Sent 37766372 bytes 24974 pkt (dropped 327, overlimits 96017 requeues 0) backlog 0b 0p requeues 0tbf segments the GSO SKBs (tbf_segment) and updates the netem's 'qlen'.The interface fully stops transferring packets and "locks". In this case,the child qdisc and tfifo are empty, but 'qlen' indicates the tfifo is atits limit and no more packets are accepted.This patch adds a counter for the entries in the tfifo. Netem's 'qlen' isonly decreased when a packet is returned by its dequeue function, and notduring enqueuing into the child qdisc. External updates to 'qlen' are thusaccounted for and only the behavior of the backlog statistics changes. Asin other qdiscs, 'qlen' then keeps track of how many packets are held innetem and all of its children. As before, sch->limit remains as themaximum number of packets in the tfifo. The same applies to netem'sbacklog statistics.

CVE-2025-39901 Severity: Moderate CVSS3 score: 5.1

Description: In the Linux kernel, the following vulnerability has been resolved:i40e: remove read access to debugfs filesThe 'command' and 'netdev_ops' debugfs files are a legacy debugginginterface supported by the i40e driver since its early days by commit02e9c290814c ("i40e: debugfs interface").Both of these debugfs files provide a read handler which is mostly useless,and which is implemented with questionable logic. They both use a static256 byte buffer which is initialized to the empty string. In the case ofthe 'command' file this buffer is literally never used and simply wastesspace. In the case of the 'netdev_ops' file, the last command written issaved here.On read, the files contents are presented as the name of the devicefollowed by a colon and then the contents of their respective staticbuffer. For 'command' this will always be ": ". For 'netdev_ops',this will be ": ". But note the buffer isshared between all devices operated by this module. At best, it is mostlymeaningless information, and at worse it could be accessed simultaneouslyas there doesn't appear to be any locking mechanism.We have also recently received multiple reports for both read functionsabout their use of snprintf and potential overflow that could result inreading arbitrary kernel memory. For the 'command' file, this is definitelyimpossible, since the static buffer is always zero and never written to.For the 'netdev_ops' file, it does appear to be possible, if the usercarefully crafts the command input, it will be copied into the buffer,which could be large enough to cause snprintf to truncate, which thencauses the copy_to_user to read beyond the length of the buffer allocatedby kzalloc.A minimal fix would be to replace snprintf() with scnprintf() which wouldcap the return to the number of bytes written, preventing an overflow. Amore involved fix would be to drop the mostly useless static buffers,saving 512 bytes and modifying the read functions to stop needing those asinput.Instead, lets just completely drop the read access to these files. Theseare debug interfaces exposed as part of debugfs, and I don't believe thatdropping read access will break any script, as the provided output ispretty useless. You can find the netdev name through other more standardinterfaces, and the 'netdev_ops' interface can easily result in garbage ifyou issue simultaneous writes to multiple devices at once.In order to properly remove the i40e_dbg_netdev_ops_buf, we need torefactor its write function to avoid using the static buffer. Instead, usethe same logic as the i40e_dbg_command_write, with an allocated buffer.Update the code to use this instead of the static buffer, and ensure wefree the buffer on exit. This fixes simultaneous writes to 'netdev_ops' onmultiple devices, and allows us to remove the now unused static bufferalong with removing the read access.

Description: In the Linux kernel, the following vulnerability has been resolved:w1: therm: Fix off-by-one buffer overflow in alarms_storeThe sysfs buffer passed to alarms_store() is allocated with 'size + 1'bytes and a NUL terminator is appended. However, the 'size' argumentdoes not account for this extra byte. The original code then allocated'size' bytes and used strcpy() to copy 'buf', which always writes onebyte past the allocated buffer since strcpy() copies until the NULterminator at index 'size'.Fix this by parsing the 'buf' parameter directly using simple_strtoll()without allocating any intermediate memory or string copying. Thisremoves the overflow while simplifying the code.

Description: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. From 1.0.9 to before 1.6.57, passing a pointer obtained from png_get_PLTE, png_get_tRNS, or png_get_hIST back into the corresponding setter on the same png_struct/png_info pair causes the setter to read from freed memory and copy its contents into the replacement buffer. The setter frees the internal buffer before copying from the caller-supplied pointer, which now dangles. The freed region may contain stale data (producing silently corrupted chunk metadata) or data from subsequent heap allocations (leaking unrelated heap contents into the chunk struct). This vulnerability is fixed in 1.6.57.

CVE-2023-54158 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: don't free qgroup space unless specifiedBoris noticed in his simple quotas testing that he was getting a leakwith Sweet Tea's change to subvol create that stopped doing atransaction commit. This was just a side effect of that change.In the delayed inode code we have an optimization that will free extrareservations if we think we can pack a dir item into an already modifiedleaf. Previously this wouldn't be triggered in the subvolume createcase because we'd commit the transaction, it was still possible butmuch harder to trigger. It could actually be triggered if we did amkdir && subvol create with qgroups enabled.This occurs because in btrfs_insert_delayed_dir_index(), which getscalled when we're adding the dir item, we do the following: btrfs_block_rsv_release(fs_info, trans->block_rsv, bytes, NULL);if we're able to skip reserving space.The problem here is that trans->block_rsv points at the temporary blockrsv for the subvolume create, which has qgroup reservations in the blockrsv.This is a problem because btrfs_block_rsv_release() will do thefollowing: if (block_rsv->qgroup_rsv_reserved >= block_rsv->qgroup_rsv_size) { qgroup_to_release = block_rsv->qgroup_rsv_reserved - block_rsv->qgroup_rsv_size; block_rsv->qgroup_rsv_reserved = block_rsv->qgroup_rsv_size; }The temporary block rsv just has ->qgroup_rsv_reserved set,->qgroup_rsv_size == 0. The optimization inbtrfs_insert_delayed_dir_index() sets ->qgroup_rsv_reserved = 0. Thenlater on when we call btrfs_subvolume_release_metadata() which has btrfs_block_rsv_release(fs_info, rsv, (u64)-1, &qgroup_to_release); btrfs_qgroup_convert_reserved_meta(root, qgroup_to_release);qgroup_to_release is set to 0, and we do not convert the reservedmetadata space.The problem here is that the block rsv code has been unconditionallymessing with ->qgroup_rsv_reserved, because the main place this is usedis delalloc, and any time we call btrfs_block_rsv_release() we do itwith qgroup_to_release set, and thus do the proper accounting.The subvolume code is the only other code that uses the qgroupreservation stuff, but it's intermingled with the above optimization,and thus was getting its reservation freed out from underneath it andthus leaking the reserved space.The solution is to simply not mess with the qgroup reservations if wedon't have qgroup_to_release set. This works with the existing code asanything that messes with the delalloc reservations always haveqgroup_to_release set. This fixes the leak that Boris was observing.

CVE-2024-50163 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Make sure internal and UAPI bpf_redirect flags don't overlapThe bpf_redirect_info is shared between the SKB and XDP redirect paths,and the two paths use the same numeric flag values in the ri->flagsfield (specifically, BPF_F_BROADCAST == BPF_F_NEXTHOP). This means thatif skb bpf_redirect_neigh() is used with a non-NULL params argument and,subsequently, an XDP redirect is performed using the samebpf_redirect_info struct, the XDP path will get confused and end upcrashing, which syzbot managed to trigger.With the stack-allocated bpf_redirect_info, the structure is no longershared between the SKB and XDP paths, so the crash doesn't happenanymore. However, different code paths using identically-numbered flagvalues in the same struct field still seems like a bit of a mess, sothis patch cleans that up by moving the flag definitions together andredefining the three flags in BPF_F_REDIRECT_INTERNAL to not overlapwith the flags used for XDP. It also adds a BUILD_BUG_ON() check to makesure the overlap is not re-introduced by mistake.

Description: In the Linux kernel, the following vulnerability has been resolved:cachefiles: Fix NULL pointer dereference in object->fileAt present, the object->file has the NULL pointer dereference problem inondemand-mode. The root cause is that the allocated fd and object->filelifetime are inconsistent, and the user-space invocation to anon_fd usesobject->file. Following is the process that triggers the issue: [write fd] [umount]cachefiles_ondemand_fd_write_iter fscache_cookie_state_machine cachefiles_withdraw_cookie if (!file) return -ENOBUFS cachefiles_clean_up_object cachefiles_unmark_inode_in_use fput(object->file) object->file = NULL // file NULL pointer dereference! __cachefiles_write(..., file, ...)Fix this issue by add an additional reference count to the object->filebefore write/llseek, and decrement after it finished.

That list is protected by the report_filterlist_lock*non-raw* spinlock which may sleep on RT kernels.Since KCSAN may report data races in any context, convert it to araw_spinlock.This requires being careful about when to allocate memory for the filterlist itself which can be done via KCSAN's debugfs interface. Concurrentmodification of the filter list via debugfs should be rare: the chosenstrategy is to optimistically pre-allocate memory before the criticalsection and discard if unused.

CVE-2024-56700 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:media: wl128x: Fix atomicity violation in fmc_send_cmd()Atomicity violation occurs when the fmc_send_cmd() function is executedsimultaneously with the modification of the fmdev->resp_skb value.Consider a scenario where, after passing the validity check within thefunction, a non-null fmdev->resp_skb variable is assigned a null value.This results in an invalid fmdev->resp_skb variable passing the validitycheck. As seen in the later part of the function, skb = fmdev->resp_skb;when the invalid fmdev->resp_skb passes the check, a null pointerdereference error may occur at line 478, evt_hdr = (void *)skb->data;To address this issue, it is recommended to include the validity check offmdev->resp_skb within the locked section of the function. Thismodification ensures that the value of fmdev->resp_skb does not changeduring the validation process, thereby maintaining its validity.This possible bug is found by an experimental static analysis tooldeveloped by our team. This tool analyzes the locking APIsto extract function pairs that can be concurrently executed, and thenanalyzes the instructions in the paired functions to identify possibleconcurrency bugs including data races and atomicity violations.

CVE-2025-21664 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:dm thin: make get_first_thin use rcu-safe list first functionThe documentation in rculist.h explains the absence of list_empty_rcu()and cautions programmers against relying on a list_empty() ->list_first() sequence in RCU safe code. This is because each of thesefunctions performs its own READ_ONCE() of the list head. This can leadto a situation where the list_empty() sees a valid list entry, but thesubsequent list_first() sees a different view of list head state after amodification.In the case of dm-thin, this author had a production box crash from a GPfault in the process_deferred_bios path. This function saw a valid listhead in get_first_thin() but when it subsequently dereferenced that andturned it into a thin_c, it got the inside of the struct pool, since thelist was now empty and referring to itself. The kernel on which thisoccurred printed both a warning about a refcount_t being saturated, anda UBSAN error for an out-of-bounds cpuid access in the queued spinlock,prior to the fault itself. When the resulting kdump was examined, itwas possible to see another thread patiently waiting in thin_dtr'ssynchronize_rcu.The thin_dtr call managed to pull the thin_c out of the active thinslist (and have it be the last entry in the active_thins list) at justthe wrong moment which lead to this crash.Fortunately, the fix here is straight forward. Switch get_first_thin()function to use list_first_or_null_rcu() which performs just a singleREAD_ONCE() and returns NULL if the list is already empty.This was run against the devicemapper test suite's thin-provisioningsuites for delete and suspend and no regressions were observed.

Description: In the Linux kernel, the following vulnerability has been resolved:eth: bnxt: always recalculate features after XDP clearing, fix null-derefRecalculate features when XDP is detached.Before: # ip li set dev eth0 xdp obj xdp_dummy.bpf.o sec xdp # ip li set dev eth0 xdp off # ethtool -k eth0 | grep gro rx-gro-hw: off [requested on]After: # ip li set dev eth0 xdp obj xdp_dummy.bpf.o sec xdp # ip li set dev eth0 xdp off # ethtool -k eth0 | grep gro rx-gro-hw: onThe fact that HW-GRO doesn't get re-enabled automatically is justa minor annoyance. The real issue is that the features will randomlycome back during another reconfiguration which just happens to invokenetdev_update_features(). The driver doesn't handle reconfiguringtwo things at a time very robustly.Starting with commit 98ba1d931f61 ("bnxt_en: Fix RSS logic in__bnxt_reserve_rings()") we only reconfigure the RSS hash tableif the "effective" number of Rx rings has changed. If HW-GRO isenabled "effective" number of rings is 2x what user sees.So if we are in the bad state, with HW-GRO re-enablement "pending"after XDP off, and we lower the rings by / 2 - the HW-GRO ringsdoing 2x and the ethtool -L doing / 2 may cancel each other out,and the: if (old_rx_rings != bp->hw_resc.resv_rx_rings &&condition in __bnxt_reserve_rings() will be false.The RSS map won't get updated, and we'll crash with: BUG: kernel NULL pointer dereference, address: 0000000000000168 RIP: 0010:__bnxt_hwrm_vnic_set_rss+0x13a/0x1a0 bnxt_hwrm_vnic_rss_cfg_p5+0x47/0x180 __bnxt_setup_vnic_p5+0x58/0x110 bnxt_init_nic+0xb72/0xf50 __bnxt_open_nic+0x40d/0xab0 bnxt_open_nic+0x2b/0x60 ethtool_set_channels+0x18c/0x1d0As we try to access a freed ring.The issue is present since XDP support was added, really, butprior to commit 98ba1d931f61 ("bnxt_en: Fix RSS logic in__bnxt_reserve_rings()") it wasn't causing major issues.

CVE-2025-21943 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:gpio: aggregator: protect driver attr handlers against module unloadBoth new_device_store and delete_device_store touch module globalresources (e.g. gpio_aggregator_lock). To prevent race conditions withmodule unload, a reference needs to be held.Add try_module_get() in these handlers.For new_device_store, this eliminates what appears to be the most dangerousscenario: if an id is allocated from gpio_aggregator_idr butplatform_device_register has not yet been called or completed, a concurrentmodule unload could fail to unregister/delete the device, leaving behind adangling platform device/GPIO forwarder. This can result in various issues.The following simple reproducer demonstrates these problems: #!/bin/bash while :; do # note: whether 'gpiochip0 0' exists or not does not matter. echo 'gpiochip0 0' > /sys/bus/platform/drivers/gpio-aggregator/new_device done & while :; do modprobe gpio-aggregator modprobe -r gpio-aggregator done & wait Starting with the following warning, several kinds of warnings will appear and the system may become unstable: ------------[ cut here ]------------ list_del corruption, ffff888103e2e980->next is LIST_POISON1 (dead000000000100) WARNING: CPU: 1 PID: 1327 at lib/list_debug.c:56 __list_del_entry_valid_or_report+0xa3/0x120 [...] RIP: 0010:__list_del_entry_valid_or_report+0xa3/0x120 [...] Call Trace: ? __list_del_entry_valid_or_report+0xa3/0x120 ? __warn.cold+0x93/0xf2 ? __list_del_entry_valid_or_report+0xa3/0x120 ? report_bug+0xe6/0x170 ? __irq_work_queue_local+0x39/0xe0 ? handle_bug+0x58/0x90 ? exc_invalid_op+0x13/0x60 ? asm_exc_invalid_op+0x16/0x20 ? __list_del_entry_valid_or_report+0xa3/0x120 gpiod_remove_lookup_table+0x22/0x60 new_device_store+0x315/0x350 [gpio_aggregator] kernfs_fop_write_iter+0x137/0x1f0 vfs_write+0x262/0x430 ksys_write+0x60/0xd0 do_syscall_64+0x6c/0x180 entry_SYSCALL_64_after_hwframe+0x76/0x7e [...] ---[ end trace 0000000000000000 ]---

CVE-2025-22027 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:media: streamzap: fix race between device disconnection and urb callbackSyzkaller has reported a general protection fault at functionir_raw_event_store_with_filter(). This crash is caused by a NULL pointerdereference of dev->raw pointer, even though it is checked for NULL inthe same function, which means there is a race condition. It occurs dueto the incorrect order of actions in the streamzap_disconnect() function:rc_unregister_device() is called before usb_kill_urb(). The dev->rawpointer is freed and set to NULL in rc_unregister_device(), and onlyafter that usb_kill_urb() waits for in-progress requests to finish.If rc_unregister_device() is called while streamzap_callback() handler isnot finished, this can lead to accessing freed resources. Thusrc_unregister_device() should be called after usb_kill_urb().Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

CVE-2025-22030 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:mm: zswap: fix crypto_free_acomp() deadlock in zswap_cpu_comp_dead()Currently, zswap_cpu_comp_dead() calls crypto_free_acomp() while holdingthe per-CPU acomp_ctx mutex. crypto_free_acomp() then holds scomp_lock(through crypto_exit_scomp_ops_async()).On the other hand, crypto_alloc_acomp_node() holds the scomp_lock (throughcrypto_scomp_init_tfm()), and then allocates memory. If the allocationresults in reclaim, we may attempt to hold the per-CPU acomp_ctx mutex.The above dependencies can cause an ABBA deadlock. For example in thefollowing scenario:(1) Task A running on CPU #1: crypto_alloc_acomp_node() Holds scomp_lock Enters reclaim Reads per_cpu_ptr(pool->acomp_ctx, 1)(2) Task A is descheduled(3) CPU #1 goes offline zswap_cpu_comp_dead(CPU #1) Holds per_cpu_ptr(pool->acomp_ctx, 1)) Calls crypto_free_acomp() Waits for scomp_lock(4) Task A running on CPU #2: Waits for per_cpu_ptr(pool->acomp_ctx, 1) // Read on CPU #1 DEADLOCKSince there is no requirement to call crypto_free_acomp() with the per-CPUacomp_ctx mutex held in zswap_cpu_comp_dead(), move it after the mutex isunlocked. Also move the acomp_request_free() and kfree() calls forconsistency and to avoid any potential sublte locking dependencies in thefuture.With this, only setting acomp_ctx fields to NULL occurs with the mutexheld. This is similar to how zswap_cpu_comp_prepare() only initializesacomp_ctx fields with the mutex held, after performing all allocationsbefore holding the mutex.Opportunistically, move the NULL check on acomp_ctx so that it takes placebefore the mutex dereference.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: harden block_group::bg_list against list_del() racesAs far as I can tell, these calls of list_del_init() on bg_list cannotrun concurrently with btrfs_mark_bg_unused() or btrfs_mark_bg_to_reclaim(),as they are in transaction error paths and situations where the blockgroup is readonly.However, if there is any chance at all of racing with mark_bg_unused(),or a different future user of bg_list, better to be safe than sorry.Otherwise we risk the following interleaving (bg_list refcount in parens)T1 (some random op) T2 (btrfs_mark_bg_unused) !list_empty(&bg->bg_list); (1)list_del_init(&bg->bg_list); (1) list_move_tail (1)btrfs_put_block_group (0) btrfs_delete_unused_bgs bg = list_first_entry list_del_init(&bg->bg_list); btrfs_put_block_group(bg); (-1)Ultimately, this results in a broken ref count that hits zero one derefearly and the real final deref underflows the refcount, resulting in a WARNING.

CVE-2025-37951 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:drm/v3d: Add job to pending list if the reset was skippedWhen a CL/CSD job times out, we check if the GPU has made any progresssince the last timeout. If so, instead of resetting the hardware, we skipthe reset and let the timer get rearmed. This gives long-running jobs achance to complete.However, when `timedout_job()` is called, the job in question is removedfrom the pending list, which means it won't be automatically freed through`free_job()`. Consequently, when we skip the reset and keep the jobrunning, the job won't be freed when it finally completes.This situation leads to a memory leak, as exposed in [1] and [2].Similarly to commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler whenGPU is still active"), this patch ensures the job is put back on thepending list when extending the timeout.

There is a closely relatedissue which has been fixed:https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d6c1b3599b2feb5c7291f5ac3a36e5fa7cedb234... but, unfortunately, the accepted patch appears to still besusceptible to a null pointer dereference under some interleavings.To trigger the bug, we think that `JFS_SBI(ipbmap->i_sb)->bmap` is setto NULL in `dbFreeBits` and then dereferenced in `jfs_ioc_trim`. Thisbug manifests quite rarely under normal circumstances, but istriggereable from a syz-program.

Description: In the Linux kernel, the following vulnerability has been resolved:nfsd: Initialize ssc before laundromat_work to prevent NULL dereferenceIn nfs4_state_start_net(), laundromat_work may access nfsd_ssc throughnfs4_laundromat -> nfsd4_ssc_expire_umount. If nfsd_ssc isn't initialized,this can cause NULL pointer dereference.Normally the delayed start of laundromat_work allows sufficient time fornfsd_ssc initialization to complete. However, when the kernel waits toolong for userspace responses (e.g. in nfs4_state_start_net ->nfsd4_end_grace -> nfsd4_record_grace_done -> nfsd4_cld_grace_done ->cld_pipe_upcall -> __cld_pipe_upcall -> wait_for_completion path), thedelayed work may start before nfsd_ssc initialization finishes.Fix this by moving nfsd_ssc initialization before starting laundromat_work.

Description: In the Linux kernel, the following vulnerability has been resolved:sched/rt: Fix race in push_rt_taskOverview========When a CPU chooses to call push_rt_task and picks a task to push toanother CPU's runqueue then it will call find_lock_lowest_rq methodwhich would take a double lock on both CPUs' runqueues. If one of thelocks aren't readily available, it may lead to dropping the currentrunqueue lock and reacquiring both the locks at once. During this windowit is possible that the task is already migrated and is running on someother CPU. These cases are already handled. However, if the task ismigrated and has already been executed and another CPU is now trying towake it up (ttwu) such that it is queued again on the runqeue(on_rq is 1) and also if the task was run by the same CPU, then thecurrent checks will pass even though the task was migrated out and is nolonger in the pushable tasks list.Crashes=======This bug resulted in quite a few flavors of crashes triggering kernelpanics with various crash signatures such as assert failures, pagefaults, null pointer dereferences, and queue corruption errors allcoming from scheduler itself.Some of the crashes:-> kernel BUG at kernel/sched/rt.c:1616!

CVE-2025-38250 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: hci_core: Fix use-after-free in vhci_flush()syzbot reported use-after-free in vhci_flush() without repro. [0]From the splat, a thread close()d a vhci file descriptor whileits device was being used by iotcl() on another thread.Once the last fd refcnt is released, vhci_release() callshci_unregister_dev(), hci_free_dev(), and kfree() for structvhci_data, which is set to hci_dev->dev->driver_data.The problem is that there is no synchronisation after unlinkinghdev from hci_dev_list in hci_unregister_dev(). There might beanother thread still accessing the hdev which was fetched beforethe unlink operation.We can use SRCU for such synchronisation.Let's run hci_dev_reset() under SRCU and wait for its completionin hci_unregister_dev().Another option would be to restore hci_dev->destruct(), which wasremoved in commit 587ae086f6e4 ("Bluetooth: Remove unusedhci-destruct cb"). However, this would not be a good solution, aswe should not run hci_unregister_dev() while there are in-flightioctl() requests, which could lead to another data-race KCSAN splat.Note that other drivers seem to have the same problem, for exmaple,virtbt_remove().[0]:BUG: KASAN: slab-use-after-free in skb_queue_empty_lockless include/linux/skbuff.h:1891 [inline]BUG: KASAN: slab-use-after-free in skb_queue_purge_reason+0x99/0x360 net/core/skbuff.c:3937Read of size 8 at addr ffff88807cb8d858 by task syz.1.219/6718CPU: 1 UID: 0 PID: 6718 Comm: syz.1.219 Not tainted 6.16.0-rc1-syzkaller-00196-g08207f42d3ff #0 PREEMPT(full)Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 05/07/2025Call Trace: dump_stack_lvl+0x189/0x250 lib/dump_stack.c:120 print_address_description mm/kasan/report.c:408 [inline] print_report+0xd2/0x2b0 mm/kasan/report.c:521 kasan_report+0x118/0x150 mm/kasan/report.c:634 skb_queue_empty_lockless include/linux/skbuff.h:1891 [inline] skb_queue_purge_reason+0x99/0x360 net/core/skbuff.c:3937 skb_queue_purge include/linux/skbuff.h:3368 [inline] vhci_flush+0x44/0x50 drivers/bluetooth/hci_vhci.c:69 hci_dev_do_reset net/bluetooth/hci_core.c:552 [inline] hci_dev_reset+0x420/0x5c0 net/bluetooth/hci_core.c:592 sock_do_ioctl+0xd9/0x300 net/socket.c:1190 sock_ioctl+0x576/0x790 net/socket.c:1311 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:907 [inline] __se_sys_ioctl+0xf9/0x170 fs/ioctl.c:893 do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline] do_syscall_64+0xfa/0x3b0 arch/x86/entry/syscall_64.c:94 entry_SYSCALL_64_after_hwframe+0x77/0x7fRIP: 0033:0x7fcf5b98e929Code: ff ff c3 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 a8 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007fcf5c7b9038 EFLAGS: 00000246 ORIG_RAX: 0000000000000010RAX: ffffffffffffffda RBX: 00007fcf5bbb6160 RCX: 00007fcf5b98e929RDX: 0000000000000000 RSI: 00000000400448cb RDI: 0000000000000009RBP: 00007fcf5ba10b39 R08: 0000000000000000 R09: 0000000000000000R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000R13: 0000000000000000 R14: 00007fcf5bbb6160 R15: 00007ffd6353d528 Allocated by task 6535: kasan_save_stack mm/kasan/common.c:47 [inline] kasan_save_track+0x3e/0x80 mm/kasan/common.c:68 poison_kmalloc_redzone mm/kasan/common.c:377 [inline] __kasan_kmalloc+0x93/0xb0 mm/kasan/common.c:394 kasan_kmalloc include/linux/kasan.h:260 [inline] __kmalloc_cache_noprof+0x230/0x3d0 mm/slub.c:4359 kmalloc_noprof include/linux/slab.h:905 [inline] kzalloc_noprof include/linux/slab.h:1039 [inline] vhci_open+0x57/0x360 drivers/bluetooth/hci_vhci.c:635 misc_open+0x2bc/0x330 drivers/char/misc.c:161 chrdev_open+0x4c9/0x5e0 fs/char_dev.c:414 do_dentry_open+0xdf0/0x1970 fs/open.c:964 vfs_open+0x3b/0x340 fs/open.c:1094 do_open fs/namei.c:3887 [inline] path_openat+0x2ee5/0x3830 fs/name---truncated---

CVE-2025-38293 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: ath11k: fix node corruption in ar->arvifs listIn current WLAN recovery code flow, ath11k_core_halt() onlyreinitializes the "arvifs" list head. This will cause thelist node immediately following the list head to become aninvalid list node. Because the prev of that node still pointsto the list head "arvifs", but the next of the list head "arvifs"no longer points to that list node.When a WLAN recovery occurs during the execution of a vifremoval, and it happens before the spin_lock_bh(&ar->data_lock)in ath11k_mac_op_remove_interface(), list_del() will detect thepreviously mentioned situation, thereby triggering a kernel panic.The fix is to remove and reinitialize all vif list nodes from thelist head "arvifs" during WLAN halt. The reinitialization is to makethe list nodes valid, ensuring that the list_del() inath11k_mac_op_remove_interface() can execute normally.Call trace:__list_del_entry_valid_or_report+0xb8/0xd0ath11k_mac_op_remove_interface+0xb0/0x27c [ath11k]drv_remove_interface+0x48/0x194 [mac80211]ieee80211_do_stop+0x6e0/0x844 [mac80211]ieee80211_stop+0x44/0x17c [mac80211]__dev_close_many+0xac/0x150__dev_change_flags+0x194/0x234dev_change_flags+0x24/0x6cdevinet_ioctl+0x3a0/0x670inet_ioctl+0x200/0x248sock_do_ioctl+0x60/0x118sock_ioctl+0x274/0x35c__arm64_sys_ioctl+0xac/0xf0invoke_syscall+0x48/0x114...Tested-on: QCA6698AQ hw2.1 PCI WLAN.HSP.1.1-04591-QCAHSPSWPL_V1_V2_SILICONZ_IOE-1

This means the df->suspended flag does not match the actualdevfreq state after initialization and msm_devfreq_get_dev_status() willend up accessing GMU registers, causing the crash.Fix this by setting df->suspended correctly during initialization.Patchwork: https://patchwork.freedesktop.org/patch/650772/

Description: In the Linux kernel, the following vulnerability has been resolved:drm/scheduler: signal scheduled fence when kill jobWhen an entity from application B is killed, drm_sched_entity_kill()removes all jobs belonging to that entity throughdrm_sched_entity_kill_jobs_work(). If application A's job depends on ascheduled fence from application B's job, and that fence is not properlysignaled during the killing process, application A's dependency cannot becleared.This leads to application A hanging indefinitely while waiting for adependency that will never be resolved. Fix this issue by ensuring thatscheduled fences are properly signaled when an entity is killed, allowingdependent applications to continue execution.

CVE-2025-38538 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:dmaengine: nbpfaxi: Fix memory corruption in probe()The nbpf->chan[] array is allocated earlier in the nbpf_probe() functionand it has "num_channels" elements. These three loops iterate oneelement farther than they should and corrupt memory.The changes to the second loop are more involved. In this case, we'recopying data from the irqbuf[] array into the nbpf->chan[] array. Ifthe data in irqbuf[i] is the error IRQ then we skip it, so the iteratorsare not in sync. I added a check to ensure that we don't go beyond theend of the irqbuf[] array. I'm pretty sure this can't happen, but itseemed harmless to add a check.On the other hand, after the loop has ended there is a check to ensurethat the "chan" iterator is where we expect it to be. In the originalcode we went one element beyond the end of the array so the iteratorwasn't in the correct place and it would always return -EINVAL. However,now it will always be in the correct place. I deleted the check sincewe know the result.

CVE-2025-38544 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: Fix bug due to prealloc collisionWhen userspace is using AF_RXRPC to provide a server, it has to preallocateincoming calls and assign to them call IDs that will be used to threadrelated recvmsg() and sendmsg() together. The preallocated call IDs willautomatically be attached to calls as they come in until the pool is empty.To the kernel, the call IDs are just arbitrary numbers, but userspace canuse the call ID to hold a pointer to prepared structs. In any case, theuser isn't permitted to create two calls with the same call ID (call IDsbecome available again when the call ends) and EBADSLT should result fromsendmsg() if an attempt is made to preallocate a call with an in-use callID.However, the cleanup in the error handling will trigger both assertions inrxrpc_cleanup_call() because the call isn't marked complete and isn'tmarked as having been released.Fix this by setting the call state in rxrpc_service_prealloc_one() and thenmarking it as being released before calling the cleanup function.

Description: In the Linux kernel, the following vulnerability has been resolved:xen: fix UAF in dmabuf_exp_from_pages()[dma_buf_fd() fixes; no preferences regarding the tree it goes through -up to xen folks]As soon as we'd inserted a file reference into descriptor table, anotherthread could close it. That's fine for the case when all we are doing isreturning that descriptor to userland (it's a race, but it's a userlandrace and there's nothing the kernel can do about it). However, if wefollow fd_install() with any kind of access to objects that would bedestroyed on close (be it the struct file itself or anything destroyedby its ->release()), we have a UAF.dma_buf_fd() is a combination of reserving a descriptor and fd_install().gntdev dmabuf_exp_from_pages() calls it and then proceeds to access theobjects destroyed on close - starting with gntdev_dmabuf itself.Fix that by doing reserving descriptor before anything else and dofd_install() only when everything had been set up.

CVE-2025-38637 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:net_sched: skbprio: Remove overly strict queue assertionsIn the current implementation, skbprio enqueue/dequeue contains an assertionthat fails under certain conditions when SKBPRIO is used as a child qdisc underTBF with specific parameters. The failure occurs because TBF sometimes peeks atpackets in the child qdisc without actually dequeuing them when tokens areunavailable.This peek operation creates a discrepancy between the parent and child qdiscqueue length counters. When TBF later receives a high-priority packet,SKBPRIO's queue length may show a different value than what's reflected in itsinternal priority queue tracking, triggering the assertion.The fix removes this overly strict assertions in SKBPRIO, they are notnecessary at all.

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-2025-68746 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:spi: tegra210-quad: Fix timeout handlingWhen the CPU that the QSPI interrupt handler runs on (typically CPU 0)is excessively busy, it can lead to rare cases of the IRQ thread notrunning before the transfer timeout is reached.While handling the timeouts, any pending transfers are cleaned up andthe message that they correspond to is marked as failed, which leavesthe curr_xfer field pointing at stale memory.To avoid this, clear curr_xfer to NULL upon timeout and check for thiscondition when the IRQ thread is finally run.While at it, also make sure to clear interrupts on failure so that newinterrupts can be run.A better, more involved, fix would move the interrupt clearing into ahard IRQ handler. Ideally we would also want to signal that the IRQthread no longer needs to be run after the timeout is hit to avoid theextra check for a valid transfer.

Description: In the Linux kernel, the following vulnerability has been resolved:hfsplus: fix missing hfs_bnode_get() in __hfs_bnode_createWhen sync() and link() are called concurrently, both threads mayenter hfs_bnode_find() without finding the node in the hash tableand proceed to create it.Thread A: hfsplus_write_inode() -> hfsplus_write_system_inode() -> hfs_btree_write() -> hfs_bnode_find(tree, 0) -> __hfs_bnode_create(tree, 0)Thread B: hfsplus_create_cat() -> hfs_brec_insert() -> hfs_bnode_split() -> hfs_bmap_alloc() -> hfs_bnode_find(tree, 0) -> __hfs_bnode_create(tree, 0)In this case, thread A creates the bnode, sets refcnt=1, and hashes it.Thread B also tries to create the same bnode, notices it has alreadybeen inserted, drops its own instance, and uses the hashed one withoutgetting the node.``` node2 = hfs_bnode_findhash(tree, cnid); if (!node2) { <- Thread A hash = hfs_bnode_hash(cnid); node->next_hash = tree->node_hash[hash]; tree->node_hash[hash] = node; tree->node_hash_cnt++; } else { <- Thread B spin_unlock(&tree->hash_lock); kfree(node); wait_event(node2->lock_wq, !test_bit(HFS_BNODE_NEW, &node2->flags)); return node2; }```However, hfs_bnode_find() requires each call to take a reference.Here both threads end up setting refcnt=1. When they later put the node,this triggers:BUG_ON(!atomic_read(&node->refcnt))In this scenario, Thread B in fact finds the node in the hash tablerather than creating a new one, and thus must take a reference.Fix this by calling hfs_bnode_get() when reusing a bnode newly created byanother thread to ensure the refcount is updated correctly.A similar bug was fixed in HFS long ago in commita9dc087fd3c4 ("fix missing hfs_bnode_get() in __hfs_bnode_create")but the same issue remained in HFS+ until now.

CVE-2025-68778 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: don't log conflicting inode if it's a dir moved in the current transactionWe can't log a conflicting inode if it's a directory and it was movedfrom one parent directory to another parent directory in the currenttransaction, as this can result an attempt to have a directory withtwo hard links during log replay, one for the old parent directory andanother for the new parent directory.The following scenario triggers that issue:1) We have directories "dir1" and "dir2" created in a past transaction. Directory "dir1" has inode A as its parent directory;2) We move "dir1" to some other directory;3) We create a file with the name "dir1" in directory inode A;4) We fsync the new file. This results in logging the inode of the new file and the inode for the directory "dir1" that was previously moved in the current transaction. So the log tree has the INODE_REF item for the new location of "dir1";5) We move the new file to some other directory. This results in updating the log tree to included the new INODE_REF for the new location of the file and removes the INODE_REF for the old location. This happens during the rename when we call btrfs_log_new_name();6) We fsync the file, and that persists the log tree changes done in the previous step (btrfs_log_new_name() only updates the log tree in memory);7) We have a power failure;8) Next time the fs is mounted, log replay happens and when processing the inode for directory "dir1" we find a new INODE_REF and add that link, but we don't remove the old link of the inode since we have not logged the old parent directory of the directory inode "dir1".As a result after log replay finishes when we trigger writeback of thesubvolume tree's extent buffers, the tree check will detect that we havea directory a hard link count of 2 and we get a mount failure.The errors and stack traces reported in dmesg/syslog are like this: [ 3845.729764] BTRFS info (device dm-0): start tree-log replay [ 3845.730304] page: refcount:3 mapcount:0 mapping:000000005c8a3027 index:0x1d00 pfn:0x11510c [ 3845.731236] memcg:ffff9264c02f4e00 [ 3845.731751] aops:btree_aops [btrfs] ino:1 [ 3845.732300] flags: 0x17fffc00000400a(uptodate|private|writeback|node=0|zone=2|lastcpupid=0x1ffff) [ 3845.733346] raw: 017fffc00000400a 0000000000000000 dead000000000122 ffff9264d978aea8 [ 3845.734265] raw: 0000000000001d00 ffff92650e6d4738 00000003ffffffff ffff9264c02f4e00 [ 3845.735305] page dumped because: eb page dump [ 3845.735981] BTRFS critical (device dm-0): corrupt leaf: root=5 block=30408704 slot=6 ino=257, invalid nlink: has 2 expect no more than 1 for dir [ 3845.737786] BTRFS info (device dm-0): leaf 30408704 gen 10 total ptrs 17 free space 14881 owner 5 [ 3845.737789] BTRFS info (device dm-0): refs 4 lock_owner 0 current 30701 [ 3845.737792] item 0 key (256 INODE_ITEM 0) itemoff 16123 itemsize 160 [ 3845.737794] inode generation 3 transid 9 size 16 nbytes 16384 [ 3845.737795] block group 0 mode 40755 links 1 uid 0 gid 0 [ 3845.737797] rdev 0 sequence 2 flags 0x0 [ 3845.737798] atime 1764259517.0 [ 3845.737800] ctime 1764259517.572889464 [ 3845.737801] mtime 1764259517.572889464 [ 3845.737802] otime 1764259517.0 [ 3845.737803] item 1 key (256 INODE_REF 256) itemoff 16111 itemsize 12 [ 3845.737805] index 0 name_len 2 [ 3845.737807] item 2 key (256 DIR_ITEM 2363071922) itemoff 16077 itemsize 34 [ 3845.737808] location key (257 1 0) type 2 [ 3845.737810] transid 9 data_len 0 name_len 4 [ 3845.737811] item 3 key (256 DIR_ITEM 2676584006) itemoff 16043 itemsize 34 [ 3845.737813] location key (258 1 0) type 2 [ 3845.737814] transid 9 data_len 0 name_len 4 [ 3845.737815] item 4 key (256 DIR_INDEX 2) itemoff 16009 itemsize 34 [ 3845.737816] location key (257 1 0) type 2 [---truncated---

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-2026-23061 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:can: kvaser_usb: kvaser_usb_read_bulk_callback(): fix URB memory leakFix similar memory leak as in commit 7352e1d5932a ("can: gs_usb:gs_usb_receive_bulk_callback(): fix URB memory leak").In kvaser_usb_set_{,data_}bittiming() -> kvaser_usb_setup_rx_urbs(), theURBs for USB-in transfers are allocated, added to the dev->rx_submittedanchor and submitted. In the complete callbackkvaser_usb_read_bulk_callback(), the URBs are processed and resubmitted. Inkvaser_usb_remove_interfaces() the URBs are freed by callingusb_kill_anchored_urbs(&dev->rx_submitted).However, this does not take into account that the USB framework unanchorsthe URB before the complete function is called. This means that once anin-URB has been completed, it is no longer anchored and is ultimately notreleased in usb_kill_anchored_urbs().Fix the memory leak by anchoring the URB in thekvaser_usb_read_bulk_callback() to the dev->rx_submitted anchor.

CVE-2026-23110 Severity: Moderate CVSS3 score: 4.7

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:net: add proper RCU protection to /proc/net/ptypeYin Fengwei reported an RCU stall in ptype_seq_show() and provideda patch.Real issue is that ptype_seq_next() and ptype_seq_show() violateRCU rules.ptype_seq_show() runs under rcu_read_lock(), and reads pt->devto get device name without any barrier.At the same time, concurrent writers can remove a packet_type structure(which is correctly freed after an RCU grace period) and clear pt->devwithout an RCU grace period.Define ptype_iter_state to carry a dev pointer along seq_net_private:struct ptype_iter_state { struct seq_net_private p; struct net_device *dev; // added in this patch};We need to record the device pointer in ptype_get_idx() andptype_seq_next() so that ptype_seq_show() is safe againstconcurrent pt->dev changes.We also need to add full RCU protection in ptype_seq_next().(Missing READ_ONCE() when reading list.next values)Many thanks to Dong Chenchen for providing a repro.

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

CVE-2026-27456 Severity: Moderate CVSS3 score: 4.7

Description: util-linux is a random collection of Linux utilities. Prior to version 2.41.4, a TOCTOU (Time-of-Check-Time-of-Use) vulnerability has been identified in the SUID binary /usr/bin/mount from util-linux. The mount binary, when setting up loop devices, validates the source file path with user privileges via fork() + setuid() + realpath(), but subsequently re-canonicalizes and opens it with root privileges (euid=0) without verifying that the path has not been replaced between both operations. Neither O_NOFOLLOW, nor inode comparison, nor post-open fstat() are employed. This allows a local unprivileged user to replace the source file with a symlink pointing to any root-owned file or device during the race window, causing the SUID binary to open and mount it as root. Exploitation requires an /etc/fstab entry with user,loop options whose path points to a directory where the attacker has write permission, and that /usr/bin/mount has the SUID bit set (the default configuration on virtually all Linux distributions). The impact is unauthorized read access to root-protected files and block devices, including backup images, disk volumes, and any file containing a valid filesystem. This issue has been patched in version 2.41.4.

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().

CVE-2026-31667 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:Input: uinput - fix circular locking dependency with ff-coreA lockdep circular locking dependency warning can be triggeredreproducibly when using a force-feedback gamepad with uinput (forexample, playing ELDEN RING under Wine with a Flydigi Vader 5controller): ff->mutex -> udev->mutex -> input_mutex -> dev->mutex -> ff->mutexThe cycle is caused by four lock acquisition paths:1. ff upload: input_ff_upload() holds ff->mutex and calls uinput_dev_upload_effect() -> uinput_request_submit() -> uinput_request_send(), which acquires udev->mutex.2. device create: uinput_ioctl_handler() holds udev->mutex and calls uinput_create_device() -> input_register_device(), which acquires input_mutex.3. device register: input_register_device() holds input_mutex and calls kbd_connect() -> input_register_handle(), which acquires dev->mutex.4. evdev release: evdev_release() calls input_flush_device() under dev->mutex, which calls input_ff_flush() acquiring ff->mutex.Fix this by introducing a new state_lock spinlock to protectudev->state and udev->dev access in uinput_request_send() instead ofacquiring udev->mutex. The function only needs to atomically checkdevice state and queue an input event into the ring buffer viauinput_dev_event() -- both operations are safe under a spinlock(ktime_get_ts64() and wake_up_interruptible() do not sleep). Thisbreaks the ff->mutex -> udev->mutex link since a spinlock is a leaf inthe lock ordering and cannot form cycles with mutexes.To keep state transitions visible to uinput_request_send(), protectwrites to udev->state in uinput_create_device() anduinput_destroy_device() with the same state_lock spinlock.Additionally, move init_completion(&request->done) fromuinput_request_send() to uinput_request_submit() beforeuinput_request_reserve_slot(). Once the slot is allocated,uinput_flush_requests() may call complete() on it at any time fromthe destroy path, so the completion must be initialised before therequest becomes visible.Lock ordering after the fix: ff->mutex -> state_lock (spinlock, leaf) udev->mutex -> state_lock (spinlock, leaf) udev->mutex -> input_mutex -> dev->mutex -> ff->mutex (no back-edge)

CVE-2026-31680 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:net: ipv6: flowlabel: defer exclusive option free until RCU teardown`ip6fl_seq_show()` walks the global flowlabel hash under the seq-fileRCU read-side lock and prints `fl->opt->opt_nflen` when an option blockis present.Exclusive flowlabels currently free `fl->opt` as soon as `fl->users`drops to zero in `fl_release()`. However, the surrounding`struct ip6_flowlabel` remains visible in the global hash table untillater garbage collection removes it and `fl_free_rcu()` finally tears itdown.A concurrent `/proc/net/ip6_flowlabel` reader can therefore race thatearly `kfree()` and dereference freed option state, triggering a crashin `ip6fl_seq_show()`.Fix this by keeping `fl->opt` alive until `fl_free_rcu()`. That matchesthe lifetime already required for the enclosing flowlabel while readerscan still reach it under RCU.

Description: In the Linux kernel, the following vulnerability has been resolved:hwmon: (occ) Fix division by zero in occ_show_power_1()In occ_show_power_1() case 1, the accumulator is divided byupdate_tag without checking for zero. If no samples have beencollected yet (e.g. during early boot when the sensor block isincluded but hasn't been updated), update_tag is zero, causinga kernel divide-by-zero crash.The 2019 fix in commit 211186cae14d ("hwmon: (occ) Fix division byzero issue") only addressed occ_get_powr_avg() used byocc_show_power_2() and occ_show_power_a0(). This separate codepath in occ_show_power_1() was missed.Fix this by reusing the existing occ_get_powr_avg() helper, whichalready handles the zero-sample case and uses mul_u64_u32_div()to multiply before dividing for better precision. Move the helperabove occ_show_power_1() so it is visible at the call site.[groeck: Fix alignment problems reported by checkpatch]

CVE-2024-40635 Severity: Moderate CVSS3 score: 4.6

Description: containerd is an open-source container runtime. A bug was found in containerd prior to versions 1.6.38, 1.7.27, and 2.0.4 where containers launched with a User set as a `UID:GID` larger than the maximum 32-bit signed integer can cause an overflow condition where the container ultimately runs as root (UID 0). This could cause unexpected behavior for environments that require containers to run as a non-root user. This bug has been fixed in containerd 1.6.38, 1.7.27, and 2.04. As a workaround, ensure that only trusted images are used and that only trusted users have permissions to import images.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: cdc-acm: Check control transfer buffer size before accessIf the first fragment is shorter than struct usb_cdc_notification, we can'tcalculate an expected_size. Log an error and discard the notificationinstead of reading lengths from memory outside the received data, which canlead to memory corruption when the expected_size decreases betweenfragments, causing `expected_size - acm->nb_index` to wrap.This issue has been present since the beginning of git history; however,it only leads to memory corruption since commit ea2583529cd1("cdc-acm: reassemble fragmented notifications").A mitigating factor is that acm_ctrl_irq() can only execute after userspacehas opened /dev/ttyACM*; but if ModemManager is running, ModemManager willdo that automatically depending on the USB device's vendor/product IDs andits other interfaces.

That said, it also checks if the "firmware" altered the valueand no longer copies them.The one, small saving grace is: Before the driver tries to read the eeprom,it needs to upload >a< firmware. the vendor firmware has a proprietarylicense and as a reason, it is not present on most distributions bydefault.

CVE-2025-68803 Severity: Moderate CVSS3 score: 4.6

Description: In the Linux kernel, the following vulnerability has been resolved:NFSD: NFSv4 file creation neglects setting ACLAn NFSv4 client that sets an ACL with a named principal during filecreation retrieves the ACL afterwards, and finds that it is only adefault ACL (based on the mode bits) and not the ACL that wasrequested during file creation. This violates RFC 8881 section6.4.1.3: "the ACL attribute is set as given".The issue occurs in nfsd_create_setattr(), which callsnfsd_attrs_valid() to determine whether to call nfsd_setattr().However, nfsd_attrs_valid() checks only for iattr changes andsecurity labels, but not POSIX ACLs. 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-2022-49814 Severity: Moderate CVSS3 score: 4.5

Description: In the Linux kernel, the following vulnerability has been resolved:kcm: close race conditions on sk_receive_queuesk->sk_receive_queue is protected by skb queue lock, but for KCMsockets its RX path takes mux->rx_lock to protect more than justskb queue. However, kcm_recvmsg() still only grabs the skb queuelock, so race conditions still exist.We can teach kcm_recvmsg() to grab mux->rx_lock too but this wouldintroduce a potential performance regression as struct kcm_mux canbe shared by multiple KCM sockets.So we have to enforce skb queue lock in requeue_rx_msgs() and handleskb peek case carefully in kcm_wait_data(). Fortunately,skb_recv_datagram() already handles it nicely and is widely used byother sockets, we can just switch to skb_recv_datagram() aftergetting rid of the unnecessary sock lock in kcm_recvmsg() andkcm_splice_read(). Side note: SOCK_DONE is not used by KCM sockets,so it is safe to get rid of this check too.I ran the original syzbot reproducer for 30 min without seeing anyissue.

CVE-2024-43790 Severity: Moderate CVSS3 score: 4.5

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

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

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

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.

CVE-2023-53503 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: allow ext4_get_group_info() to failPreviously, ext4_get_group_info() would treat an invalid group numberas BUG(), since in theory it should never happen. However, if amalicious attaker (or fuzzer) modifies the superblock via the blockdevice while it is the file system is mounted, it is possible fors_first_data_block to get set to a very large number. In that case,when calculating the block group of some block number (such as thestarting block of a preallocation region), could result in anunderflow and very large block group number. Then the BUG_ON check inext4_get_group_info() would fire, resutling in a denial of serviceattack that can be triggered by root or someone with write access tothe block device.For a quality of implementation perspective, it's best that even ifthe system administrator does something that they shouldn't, that itwill not trigger a BUG. So instead of BUG'ing, ext4_get_group_info()will call ext4_error and return NULL. We also add fallback code inall of the callers of ext4_get_group_info() that it might NULL.Also, since ext4_get_group_info() was already borderline to be aninline function, un-inline it. The results in a next reduction of thecompiled text size of ext4 by roughly 2k.

Description: In the Linux kernel, the following vulnerability has been resolved:vfio/pci: Lock external INTx masking opsMask operations through config space changes to DisINTx may race INTxconfiguration changes via ioctl. Create wrappers that add locking forpaths outside of the core interrupt code.In particular, irq_type is updated holding igate, therefore testingis_intx() requires holding igate. For example clearing DisINTx fromconfig space can otherwise race changes of the interrupt configuration.This aligns interfaces which may trigger the INTx eventfd into twocamps, one side serialized by igate and the other only enabled whileINTx is configured. A subsequent patch introduces synchronization forthe latter flows.

CVE-2024-45306 Severity: Moderate CVSS3 score: 4.4

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

This results in an infinite loop:entry_tc -> subprog_tc -> entry_freplace --tailcall-> entry_tc.The problem arises because the tail_call_cnt in entry_freplace resets tozero each time entry_freplace is executed, causing the tail call mechanismto never terminate, eventually leading to a kernel panic.To fix this issue, the solution is twofold:1. Prevent updating a program extended by an freplace program to a prog_array map.2. Prevent extending a program that is already part of a prog_array map with an freplace program.This ensures that:* If a program or its subprogram has been extended by an freplace program, it can no longer be updated to a prog_array map.* If a program has been added to a prog_array map, neither it nor its subprograms can be extended by an freplace program.Moreover, an extension program should not be tailcalled. As such, return-EINVAL if the program has a type of BPF_PROG_TYPE_EXT when adding it to aprog_array map.Additionally, fix a minor code style issue by replacing eight spaces with atab for proper formatting.

Description: In the Linux kernel, the following vulnerability has been resolved:mm: hugetlb: independent PMD page table shared countThe folio refcount may be increased unexpectly through try_get_folio() bycaller such as split_huge_pages. In huge_pmd_unshare(), we use refcountto check whether a pmd page table is shared. The check is incorrect ifthe refcount is increased by the above caller, and this can cause the pagetable leaked: BUG: Bad page state in process sh pfn:109324 page: refcount:0 mapcount:0 mapping:0000000000000000 index:0x66 pfn:0x109324 flags: 0x17ffff800000000(node=0|zone=2|lastcpupid=0xfffff) page_type: f2(table) raw: 017ffff800000000 0000000000000000 0000000000000000 0000000000000000 raw: 0000000000000066 0000000000000000 00000000f2000000 0000000000000000 page dumped because: nonzero mapcount ...

The page table itself will be discarded after reporting the "nonzero mapcount".2. The HugeTLB page mapped by the page table miss freeing since we treat the page table as shared and a shared page table will not be unmapped.Fix it by introducing independent PMD page table shared count. Asdescribed by comment, pt_index/pt_mm/pt_frag_refcount are used for s390gmap, x86 pgds and powerpc, pt_share_count is used for x86/arm64/riscvpmds, so we can reuse the field as pt_share_count.

CVE-2025-37927 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:iommu/amd: Fix potential buffer overflow in parse_ivrs_acpihidThere is a string parsing logic error which can lead to an overflow of hidor uid buffers. Comparing ACPIID_LEN against a total string length doesn'ttake into account the lengths of individual hid and uid buffers so thecheck is insufficient in some cases. For example if the length of hidstring is 4 and the length of the uid string is 260, the length of strwill be equal to ACPIID_LEN + 1 but uid string will overflow uid bufferwhich size is 256.The same applies to the hid string with length 13 and uid string withlength 250.Check the length of hid and uid strings separately to preventbuffer overflow.Found by Linux Verification Center (linuxtesting.org) with SVACE.

CVE-2025-38100 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:x86/iopl: Cure TIF_IO_BITMAP inconsistenciesio_bitmap_exit() is invoked from exit_thread() when a task exists orwhen a fork fails. In the latter case the exit_thread() cleans upresources which were allocated during fork().io_bitmap_exit() invokes task_update_io_bitmap(), which in turn ends upin tss_update_io_bitmap(). tss_update_io_bitmap() operates on thecurrent task. If current has TIF_IO_BITMAP set, but no bitmap installed,tss_update_io_bitmap() crashes with a NULL pointer dereference.There are two issues, which lead to that problem: 1) io_bitmap_exit() should not invoke task_update_io_bitmap() when the task, which is cleaned up, is not the current task. That's a clear indicator for a cleanup after a failed fork(). 2) A task should not have TIF_IO_BITMAP set and neither a bitmap installed nor IOPL emulation level 3 activated. This happens when a kernel thread is created in the context of a user space thread, which has TIF_IO_BITMAP set as the thread flags are copied and the IO bitmap pointer is cleared. Other than in the failed fork() case this has no impact because kernel threads including IO workers never return to user space and therefore never invoke tss_update_io_bitmap().Cure this by adding the missing cleanups and checks: 1) Prevent io_bitmap_exit() to invoke task_update_io_bitmap() if the to be cleaned up task is not the current task. 2) Clear TIF_IO_BITMAP in copy_thread() unconditionally. For user space forks it is set later, when the IO bitmap is inherited in io_bitmap_share().For paranoia sake, add a warning into tss_update_io_bitmap() to catchthe case, when that code is invoked with inconsistent state.

CVE-2025-38591 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Reject narrower access to pointer ctx fieldsThe following BPF program, simplified from a syzkaller repro, causes akernel warning: r0 = *(u8 *)(r1 + 169); exit;With pointer field sk being at offset 168 in __sk_buff. This access isdetected as a narrower read in bpf_skb_is_valid_access because itdoesn't match offsetof(struct __sk_buff, sk). It is therefore allowedand later proceeds to bpf_convert_ctx_access. Note that for the"is_narrower_load" case in the convert_ctx_accesses(), the insn->offis aligned, so the cnt may not be 0 because it matches theoffsetof(struct __sk_buff, sk) in the bpf_convert_ctx_access. However,the target_size stays 0 and the verifier errors with a kernel warning: verifier bug: error during ctx access conversion(1)This patch fixes that to return a proper "invalid bpf_context accessoff=X size=Y" error on the load instruction.The same issue affects multiple other fields in context structures thatallow narrow access. Some other non-affected fields (for sk_msg,sk_lookup, and sockopt) were also changed to use bpf_ctx_range_ptr forconsistency.Note this syzkaller crash was reported in the "Closes" link below, whichused to be about a different bug, fixed incommit fce7bd8e385a ("bpf/verifier: Handle BPF_LOAD_ACQ instructionsin insn_def_regno()"). Because syzbot somehow confused the two bugs,the new crash and repro didn't get reported to the mailing list.

CVE-2025-39706 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amdkfd: Destroy KFD debugfs after destroy KFD wqSince KFD proc content was moved to kernel debugfs, we can't destroy KFDdebugfs before kfd_process_destroy_wq. Move kfd_process_destroy_wq priorto kfd_debugfs_fini to fix a kernel NULL pointer problem. It happenswhen /sys/kernel/debug/kfd was already destroyed in kfd_debugfs_fini butkfd_process_destroy_wq calls kfd_debugfs_remove_process. This line debugfs_remove_recursive(entry->proc_dentry);tries to remove /sys/kernel/debug/kfd/proc/ while/sys/kernel/debug/kfd is already gone. It hangs the kernel by kernelNULL pointer.(cherry picked from commit 0333052d90683d88531558dcfdbf2525cc37c233)

That explains why there is no backref item for thatbytenr and why btrfs check is not reporting anything wrong.But this also shows another problem, as btrfs will do all the orphansubvolume cleanup at a read-write mount.So half-dropped subvolume should not exist after an RW mount, andbalance itself is also exclusive to subvolume cleanup, meaning weshouldn't hit a subvolume half-dropped during relocation.The root cause is, there is no orphan item for this subvolume.In fact there are 5 subvolumes from around 2021 that have the sameproblem.It looks like the original report has some older kernels running, andcaused those zombie subvolumes.Thankfully upstream commit 8d488a8c7ba2 ("btrfs: fix subvolume/snapshotdeletion not triggered on mount") has long fixed the bug.[ENHANCEMENT]For repairing such old fs, btrfs-progs will be enhanced.Considering how delayed the problem will show up (at run delayed reftime) and at that time we have to abort transaction already, it is toolate.Instead here we reject any half-dropped subvolume for reloc tree at theearliest time, preventing confusion and extra time wasted on debuggingsimilar bugs.

CVE-2025-39763 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:ACPI: APEI: send SIGBUS to current task if synchronous memory error not recoveredIf a synchronous error is detected as a result of user-space processtriggering a 2-bit uncorrected error, the CPU will take a synchronouserror exception such as Synchronous External Abort (SEA) on Arm64. Thekernel will queue a memory_failure() work which poisons the relatedpage, unmaps the page, and then sends a SIGBUS to the process, so thata system wide panic can be avoided.However, no memory_failure() work will be queued when abnormalsynchronous errors occur. These errors can include situations likeinvalid PA, unexpected severity, no memory failure config support,invalid GUID section, etc. In such a case, the user-space process willtrigger SEA again. This loop can potentially exceed the platformfirmware threshold or even trigger a kernel hard lockup, leading to asystem reboot.Fix it by performing a force kill if no memory_failure() work is queuedfor synchronous errors.[ rjw: Changelog edits ]

CVE-2025-39958 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:iommu/s390: Make attach succeed when the device was surprise removedWhen a PCI device is removed with surprise hotplug, there may still beattempts to attach the device to the default domain as part of tear downvia (__iommu_release_dma_ownership()), or because the removal happensduring probe (__iommu_probe_device()). In both cases zpci_register_ioat()fails with a cc value indicating that the device handle is invalid. Thisis because the device is no longer part of the instance as far as thehypervisor is concerned.Currently this leads to an error return and s390_iommu_attach_device()fails. This triggers the WARN_ON() in __iommu_group_set_domain_nofail()because attaching to the default domain must never fail.With the device fenced by the hypervisor no DMAs to or from memory arepossible and the IOMMU translations have no effect. Proceed as if theregistration was successful and let the hotplug event handling clean upthe device.This is similar to how devices in the error state are handled sincecommit 59bbf596791b ("iommu/s390: Make attach succeed even if the deviceis in error state") except that for removal the domain will not beregistered later. This approach was also previously discussed at thelink.Handle both cases, error state and removal, in a helper which checks ifthe error needs to be propagated or ignored. Avoid magic numbercondition codes by using the pre-existing, but never used, defines forPCI load/store condition codes and rename them to reflect that theyapply to all PCI instructions.

Description: In the Linux kernel, the following vulnerability has been resolved:net: sched: act_connmark: initialize struct tc_ife to fix kernel leakIn tcf_connmark_dump(), the variable 'opt' was partially initialized using adesignatied initializer. While the padding bytes are reamineduninitialized. nla_put() copies the entire structure into anetlink message, these uninitialized bytes leaked to userspace.Initialize the structure with memset before assigning its fieldsto ensure all members and padding are cleared prior to beign copied.

CVE-2025-40301 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: hci_event: validate skb length for unknown CC opcodeIn hci_cmd_complete_evt(), if the command complete event has an unknownopcode, we assume the first byte of the remaining skb->data contains thereturn status. However, parameter data has previously been pulled inhci_event_func(), which may leave the skb empty. If so, using skb->data[0]for the return status uses un-init memory.The fix is to check skb->len before using skb->data.

There was a device discovery/fabric scan inprogress. A module unload was issued which set the UNLOADING flag. Aspart of the discovery, after receiving an interrupt a work queue wasscheduled (which involved a work to be queued). Since the UNLOADINGflag is set, the work item was not allocated and the mapped memory hadto be freed. The free occurred in interrupt context leading to systemcrash. Delay the driver unload until the fabric scan is complete toavoid the crash.

CVE-2026-22981 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:idpf: detach and close netdevs while handling a resetProtect the reset path from callbacks by setting the netdevs to detachedstate and close any netdevs in UP state until the reset handling hascompleted. During a reset, the driver will de-allocate resources for thevport, and there is no guarantee that those will recover, which is why theexisting vport_ctrl_lock does not provide sufficient protection.idpf_detach_and_close() is called right before reset handling. If thereset handling succeeds, the netdevs state is recovered via call toidpf_attach_and_open(). If the reset handling fails the netdevs remaindown. The detach/down calls are protected with RTNL lock to avoid racingwith callbacks. On the recovery side the attach can be done withoutholding the RTNL lock as there are no callbacks expected at that point,due to detach/close always being done first in that flow.The previous logic restoring the netdevs state based on theIDPF_VPORT_UP_REQUESTED flag in the init task is not needed anymore, hencethe removal of idpf_set_vport_state(). The IDPF_VPORT_UP_REQUESTED isstill being used to restore the state of the netdevs following the reset,but has no use outside of the reset handling flow.idpf_init_hard_reset() is converted to void, since it was used as such andthere is no error handling being done based on its return value.Before this change, invoking hard and soft resets simultaneously willcause the driver to lose the vport state:ip -br a UPecho 1 > /sys/class/net/ens801f0/device/reset& \ethtool -L ens801f0 combined 8ip -br a DOWNip link set upip -br a DOWNAlso in case of a failure in the reset path, the netdev is leftexposed to external callbacks, while vport resources are notinitialized, leading to a crash on subsequent ifup/down:[408471.398966] idpf 0000:83:00.0: HW reset detected[408471.411744] idpf 0000:83:00.0: Device HW Reset initiated[408472.277901] idpf 0000:83:00.0: The driver was unable to contact the device's firmware.

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.

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)

CVE-2026-23292 Severity: Moderate CVSS3 score: 4.4

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-2026-31415 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---

CVE-2026-31668 Severity: Moderate CVSS3 score: 4.4

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.

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.

CVE-2026-23206 Severity: Moderate CVSS3 score: 4.3

Description: In the Linux kernel, the following vulnerability has been resolved:dpaa2-switch: prevent ZERO_SIZE_PTR dereference when num_ifs is zeroThe driver allocates arrays for ports, FDBs, and filter blocks usingkcalloc() with ethsw->sw_attr.num_ifs as the element count. When thedevice reports zero interfaces (either due to hardware configurationor firmware issues), kcalloc(0, ...) returns ZERO_SIZE_PTR (0x10)instead of NULL.Later in dpaa2_switch_probe(), the NAPI initialization unconditionallyaccesses ethsw->ports[0]->netdev, which attempts to dereferenceZERO_SIZE_PTR (address 0x10), resulting in a kernel panic.Add a check to ensure num_ifs is greater than zero after retrievingdevice attributes. This prevents the zero-sized allocations andsubsequent invalid pointer dereference.

Description: In the Linux kernel, the following vulnerability has been resolved:af_netlink: Fix shift out of bounds in group mask calculationWhen a netlink message is received, netlink_recvmsg() fills in the addressof the sender. One of the fields is the 32-bit bitfield nl_groups, whichcarries the multicast group on which the message was received. The leastsignificant bit corresponds to group 1, and therefore the highest groupthat the field can represent is 32. Above that, the UB sanitizer flags theout-of-bounds shift attempts.Which bits end up being set in such case is implementation defined, butit's either going to be a wrong non-zero value, or zero, which is at leastnot misleading. Make the latter choice deterministic by always setting to 0for higher-numbered multicast groups.To get information about membership in groups >= 32, userspace is expectedto use nl_pktinfo control messages[0], which are enabled by NETLINK_PKTINFOsocket option.[0] https://lwn.net/Articles/147608/The way to trigger this issue is e.g. through monitoring the BRVLAN group: # bridge monitor vlan & # ip link add name br type bridgeWhich produces the following citation: UBSAN: shift-out-of-bounds in net/netlink/af_netlink.c:162:19 shift exponent 32 is too large for 32-bit type 'int'

CVE-2024-49878 Severity: Moderate CVSS3 score: 4.2

Description: In the Linux kernel, the following vulnerability has been resolved:resource: fix region_intersects() vs add_memory_driver_managed()On a system with CXL memory, the resource tree (/proc/iomem) related toCXL memory may look like something as follows.490000000-50fffffff : CXL Window 0 490000000-50fffffff : region0 490000000-50fffffff : dax0.0 490000000-50fffffff : System RAM (kmem)Because drivers/dax/kmem.c calls add_memory_driver_managed() duringonlining CXL memory, which makes "System RAM (kmem)" a descendant of "CXLWindow X". This confuses region_intersects(), which expects all "SystemRAM" resources to be at the top level of iomem_resource. This can lead tobugs.For example, when the following command line is executed to write somememory in CXL memory range via /dev/mem, $ dd if=data of=/dev/mem bs=$((1 << 10)) seek=$((0x490000000 >> 10)) count=1 dd: error writing '/dev/mem': Bad address 1+0 records in 0+0 records out 0 bytes copied, 0.0283507 s, 0.0 kB/sthe command fails as expected. However, the error code is wrong. Itshould be "Operation not permitted" instead of "Bad address". Moreseriously, the /dev/mem permission checking in devmem_is_allowed() passesincorrectly. Although the accessing is prevented later because ioremap()isn't allowed to map system RAM, it is a potential security issue. Duringcommand executing, the following warning is reported in the kernel log forcalling ioremap() on system RAM. ioremap on RAM at 0x0000000490000000 - 0x0000000490000fff WARNING: CPU: 2 PID: 416 at arch/x86/mm/ioremap.c:216 __ioremap_caller.constprop.0+0x131/0x35d Call Trace: memremap+0xcb/0x184 xlate_dev_mem_ptr+0x25/0x2f write_mem+0x94/0xfb vfs_write+0x128/0x26d ksys_write+0xac/0xfe do_syscall_64+0x9a/0xfd entry_SYSCALL_64_after_hwframe+0x4b/0x53The details of command execution process are as follows. In the aboveresource tree, "System RAM" is a descendant of "CXL Window 0" instead of atop level resource. So, region_intersects() will report no System RAMresources in the CXL memory region incorrectly, because it only checks thetop level resources. Consequently, devmem_is_allowed() will return 1(allow access via /dev/mem) for CXL memory region incorrectly. Fortunately, ioremap() doesn't allow to map System RAM and reject theaccess.So, region_intersects() needs to be fixed to work correctly with theresource tree with "System RAM" not at top level as above. To fix it, ifwe found a unmatched resource in the top level, we will continue to searchmatched resources in its descendant resources. So, we will not miss anymatched resources in resource tree anymore.In the new implementation, an example resource tree|------------- "CXL Window 0" ------------||-- "System RAM" --|will behave similar as the following fake resource tree forregion_intersects(, IORESOURCE_SYSTEM_RAM, ),|-- "System RAM" --||-- "CXL Window 0a" --|Where "CXL Window 0a" is part of the original "CXL Window 0" thatisn't covered by "System RAM".

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

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

CVE-2022-49124 Severity: Moderate CVSS3 score: 4.1

Description: In the Linux kernel, the following vulnerability has been resolved:x86/mce: Work around an erratum on fast string copy instructionsA rare kernel panic scenario can happen when the following conditionsare met due to an erratum on fast string copy instructions:1) An uncorrected error.2) That error must be in first cache line of a page.3) Kernel must execute page_copy from the page immediately before thatpage.The fast string copy instructions ("REP; MOVS*") could consume anuncorrectable memory error in the cache line _right after_ the desiredregion to copy and raise an MCE.Bit 0 of MSR_IA32_MISC_ENABLE can be cleared to disable fast stringcopy and will avoid such spurious machine checks. However, that is lesspreferable due to the permanent performance impact. Considering memorypoison is rare, it's desirable to keep fast string copy enabled until anMCE is seen.Intel has confirmed the following:1. The CPU erratum of fast string copy only applies to Skylake,Cascade Lake and Cooper Lake generations.Directly return from the MCE handler:2. Will result in complete execution of the "REP; MOVS*" with no dataloss or corruption.3. Will not result in another MCE firing on the next poisoned cache linedue to "REP; MOVS*".4. Will resume execution from a correct point in code.5. Will result in the same instruction that triggered the MCE firing asecond MCE immediately for any other software recoverable data fetcherrors.6. Is not safe without disabling the fast string copy, as the next faststring copy of the same buffer on the same CPU would result in a PANICMCE.This should mitigate the erratum completely with the only caveat thatthe fast string copy is disabled on the affected hyper thread thusperformance degradation.This is still better than the OS crashing on MCEs raised on anirrelevant process due to "REP; MOVS*' accesses in a kernel context,e.g., copy_page.Injected errors on 1st cache line of 8 anonymous pages of process'proc1' and observed MCE consumption from 'proc2' with no panic(directly returned).Without the fix, the host panicked within a few minutes on arandom 'proc2' process due to kernel access from copy_page.

However, while ltp runningstress tests, it was observed that in case of some error handling paths, it ispossible for update_super_work to start a transaction after the journal isdestroyed eg:(umount)ext4_kill_sb kill_block_super generic_shutdown_super sync_filesystem /* commits all txns */ evict_inodes /* might start a new txn */ ext4_put_super flush_work(&sbi->s_sb_upd_work) /* flush the workqueue */ jbd2_journal_destroy journal_kill_thread journal->j_flags |= JBD2_UNMOUNT; jbd2_journal_commit_transaction jbd2_journal_get_descriptor_buffer jbd2_journal_bmap ext4_journal_bmap ext4_map_blocks ... ext4_inode_error ext4_handle_error schedule_work(&sbi->s_sb_upd_work) /* work queue kicks in */ update_super_work jbd2_journal_start start_this_handle BUG_ON(journal->j_flags & JBD2_UNMOUNT)Hence, introduce a new mount flag to indicate journal is destroying and only doa journaled (and deferred) update of sb if this flag is not set. Otherwise, justfallback to an un-journaled commit.Further, in the journal destroy path, we have the following sequence: 1. Set mount flag indicating journal is destroying 2. force a commit and wait for it 3. flush pending sb updatesThis sequence is important as it ensures that, after this point, there is no sbupdate that might be journaled so it is safe to update the sb outside thejournal. (To avoid race discussed in 2d01ddc86606)Also, we don't need a similar check in ext4_grp_locked_error since it is onlycalled from mballoc and AFAICT it would be always valid to schedule work here.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: mpi3mr: Synchronous access b/w reset and tm thread for reply queueWhen the task management thread processes reply queues while the resetthread resets them, the task management thread accesses an invalid queue ID(0xFFFF), set by the reset thread, which points to unallocated memory,causing a crash.Add flag 'io_admin_reset_sync' to synchronize access between the reset,I/O, and admin threads. Before a reset, the reset handler sets this flag toblock I/O and admin processing threads. If any thread bypasses the initialcheck, the reset thread waits up to 10 seconds for processing to finish. Ifthe wait exceeds 10 seconds, the controller is marked as unrecoverable.

Description: In the Linux kernel, the following vulnerability has been resolved:ata: pata_via: Force PIO for ATAPI devices on VT6415/VT6330The controller has a hardware bug that can hard hang the system whendoing ATAPI DMAs without any trace of what happened. Depending on thedevice attached, it can also prevent the system from booting.In this case, the system hangs when reading the ATIP from optical mediawith cdrecord -vvv -atip on an _NEC DVD_RW ND-4571A 1-01 and anOptiarc DVD RW AD-7200A 1.06 attached to an ASRock 990FX Extreme 4,running at UDMA/33.The issue can be reproduced by running the same command with a cygwinbuild of cdrecord on WinXP, although it requires more attempts to causeit. The hang in that case is also resolved by forcing PIO. It doesn'tappear that VIA has produced any drivers for that OS, thus no knownworkaround exists.HDDs attached to the controller do not suffer from any DMA issues.

CVE-2025-53905 Severity: Moderate CVSS3 score: 4.1

Description: Vim is an open source, command line text editor. Prior to version 9.1.1552, a path traversal issue in Vim's tar.vim plugin can allow overwriting of arbitrary files when opening specially crafted tar 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 9.1.1552 contains a patch for the vulnerability.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix invalid prog->stats access when update_effective_progs failsSyzkaller triggers an invalid memory access issue following faultinjection in update_effective_progs. The issue can be described asfollows:__cgroup_bpf_detach update_effective_progs compute_effective_progs bpf_prog_array_alloc <-- fault inject purge_effective_progs /* change to dummy_bpf_prog */ array->items[index] = &dummy_bpf_prog.prog---softirq start---__do_softirq ... __cgroup_bpf_run_filter_skb __bpf_prog_run_save_cb bpf_prog_run stats = this_cpu_ptr(prog->stats) /* invalid memory access */ flags = u64_stats_update_begin_irqsave(&stats->syncp)---softirq end--- static_branch_dec(&cgroup_bpf_enabled_key[atype])The reason is that fault injection caused update_effective_progs to failand then changed the original prog into dummy_bpf_prog.prog inpurge_effective_progs. Then a softirq came, and accessing the members ofdummy_bpf_prog.prog in the softirq triggers invalid mem access.To fix it, skip updating stats when stats is NULL.

CVE-2025-71079 Severity: Moderate CVSS3 score: 4.1

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

CVE-2026-23361 Severity: Moderate CVSS3 score: 4.1

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: dwc: ep: Flush MSI-X write before unmapping its ATU entryEndpoint drivers use dw_pcie_ep_raise_msix_irq() to raise an MSI-Xinterrupt to the host using a writel(), which generates a PCI posted writetransaction. There's no completion for posted writes, so the writel() mayreturn before the PCI write completes. dw_pcie_ep_raise_msix_irq() alsounmaps the outbound ATU entry used for the PCI write, so the write raceswith the unmap.If the PCI write loses the race with the ATU unmap, the write may corrupthost memory or cause IOMMU errors, e.g., these when running fio with alarger queue depth against nvmet-pci-epf: arm-smmu-v3 fc900000.iommu: 0x0000010000000010 arm-smmu-v3 fc900000.iommu: 0x0000020000000000 arm-smmu-v3 fc900000.iommu: 0x000000090000f040 arm-smmu-v3 fc900000.iommu: 0x0000000000000000 arm-smmu-v3 fc900000.iommu: event: F_TRANSLATION client: 0000:01:00.0 sid: 0x100 ssid: 0x0 iova: 0x90000f040 ipa: 0x0 arm-smmu-v3 fc900000.iommu: unpriv data write s1 "Input address caused fault" stag: 0x0Flush the write by performing a readl() of the same address to ensure thatthe write has reached the destination before the ATU entry is unmapped.The same problem was solved for dw_pcie_ep_raise_msi_irq() in commit8719c64e76bf ("PCI: dwc: ep: Cache MSI outbound iATU mapping"), but thereit was solved by dedicating an outbound iATU only for MSI. We can't do thesame for MSI-X because each vector can have a different msg_addr and themsg_addr may be changed while the vector is masked.[bhelgaas: commit log]

CVE-2022-50476 Severity: Moderate CVSS3 score: 3.7

Description: In the Linux kernel, the following vulnerability has been resolved:ntb_netdev: Use dev_kfree_skb_any() in interrupt contextTX/RX callback handlers (ntb_netdev_tx_handler(),ntb_netdev_rx_handler()) can be called in interruptcontext via the DMA framework when the respectiveDMA operations have completed. As such, any callsby these routines to free skb's, should use theinterrupt context safe dev_kfree_skb_any() function.Previously, these callback handlers would call theinterrupt unsafe version of dev_kfree_skb(). This hasnot presented an issue on Intel IOAT DMA engines asthat driver utilizes tasklets rather than a hardinterrupt handler, like the AMD PTDMA DMA driver.On AMD systems, a kernel WARNING message isencountered, which is being issued fromskb_release_head_state() due to in_hardirq()being true.Besides the user visible WARNING from the kernel,the other symptom of this bug was that TCP/IP performanceacross the ntb_netdev interface was very poor, i.e.approximately an order of magnitude below what wasexpected. With the repair to use dev_kfree_skb_any(),kernel WARNINGs from skb_release_head_state() ceasedand TCP/IP performance, as measured by iperf, was onpar with expected results, approximately 20 Gb/s onAMD Milan based server. Note that this performanceis comparable with Intel based servers.

CVE-2026-0989 Severity: Moderate CVSS3 score: 3.7

Description: A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk.

CVE-2025-38067 Severity: Moderate CVSS3 score: 3.6

Description: In the Linux kernel, the following vulnerability has been resolved:rseq: Fix segfault on registration when rseq_cs is non-zeroThe rseq_cs field is documented as being set to 0 by user-space prior toregistration, however this is not currently enforced by the kernel. Thiscan result in a segfault on return to user-space if the value stored inthe rseq_cs field doesn't point to a valid struct rseq_cs.The correct solution to this would be to fail the rseq registration whenthe rseq_cs field is non-zero. However, some older versions of glibcwill reuse the rseq area of previous threads without clearing therseq_cs field and will also terminate the process if the rseqregistration fails in a secondary thread. This wasn't caught in testingbecause in this case the leftover rseq_cs does point to a valid structrseq_cs.What we can do is clear the rseq_cs field on registration when it'snon-zero which will prevent segfaults on registration and won't breakthe glibc versions that reuse rseq areas on thread creation.

CVE-2025-38047 Severity: Moderate CVSS3 score: 3.4

Description: In the Linux kernel, the following vulnerability has been resolved:x86/fred: Fix system hang during S4 resume with FRED enabledUpon a wakeup from S4, the restore kernel starts and initializes theFRED MSRs as needed from its perspective. It then loads a hibernationimage, including the image kernel, and attempts to load image pagesdirectly into their original page frames used before hibernation unlessthose frames are currently in use. Once all pages are moved to theiroriginal locations, it jumps to a "trampoline" page in the image kernel.At this point, the image kernel takes control, but the FRED MSRs stillcontain values set by the restore kernel, which may differ from thoseset by the image kernel before hibernation. Therefore, the image kernelmust ensure the FRED MSRs have the same values as before hibernation.Since these values depend only on the location of the kernel text anddata, they can be recomputed from scratch.

CVE-2024-50060 Severity: Moderate CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring: check if we need to reschedule during overflow flushIn terms of normal application usage, this list will always be empty.And if an application does overflow a bit, it'll have a few entries.However, nothing obviously prevents syzbot from running a test casethat generates a ton of overflow entries, and then flushing them cantake quite a while.Check for needing to reschedule while flushing, and drop our locks anddo so if necessary. There's no state to maintain here as overflowsalways prune from head-of-list, hence it's fine to drop and reacquirethe locks at the end of the loop.

Since the vPMU is requested, but not setup, kvm_arm_pmu_v3_enable() fails in kvm_arch_vcpu_run_pid_change(). As a result, KVM_RUN returns after enabling the timer, but before incrementing 'userspace_irqchip_in_use': kvm_arch_vcpu_run_pid_change() ret = kvm_arm_pmu_v3_enable() if (!vcpu->arch.pmu.created) return -EINVAL; if (ret) return ret; [...] if (!irqchip_in_kernel(kvm)) static_branch_inc(&userspace_irqchip_in_use); - Userspace ignores the error and issues KVM_ARM_VCPU_INIT again. Since the timer is already enabled, control moves through the following flow, ultimately hitting the WARN_ON(): kvm_timer_vcpu_reset() if (timer->enabled) kvm_timer_update_irq() if (!userspace_irqchip()) ret = kvm_vgic_inject_irq() ret = vgic_lazy_init() if (unlikely(!vgic_initialized(kvm))) if (kvm->arch.vgic.vgic_model != KVM_DEV_TYPE_ARM_VGIC_V2) return -EBUSY; WARN_ON(ret);Theoretically, since userspace_irqchip_in_use's functionality can besimply replaced by '!irqchip_in_kernel()', get rid of the static keyto avoid the mismanagement, which also helps with the syzbot issue.

CVE-2024-53198 Severity: Moderate CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:xen: Fix the issue of resource not being properly released in xenbus_dev_probe()This patch fixes an issue in the function xenbus_dev_probe(). In thexenbus_dev_probe() function, within the if (err) branch at line 313, theprogram incorrectly returns err directly without releasing the resourcesallocated by err = drv->probe(dev, id). As the return value is non-zero,the upper layers assume the processing logic has failed. However, the probeoperation was performed earlier without a corresponding remove operation.Since the probe actually allocates resources, failing to perform the removeoperation could lead to problems.To fix this issue, we followed the resource release logic of thexenbus_dev_remove() function by adding a new block fail_remove before thefail_put block. After entering the branch if (err) at line 313, thefunction will use a goto statement to jump to the fail_remove block,ensuring that the previously acquired resources are correctly released,thus preventing the reference count leak.This bug was identified by an experimental static analysis tool developedby our team. The tool specializes in analyzing reference count operationsand detecting potential issues where resources are not properly managed.In this case, the tool flagged the missing release operation as apotential problem, which led to the development of this patch.

So they will mismatch this fieldeasily.This patch solves it by using another bit(defined asSK_USER_DATA_PSOCK) in PTRMASK, to mark whethersk_user_data points to a psock object or not.This patch depends on a PTRMASK introduced in commit f1ff5ce2cd5e("net, sk_msg: Clear sk_user_data pointer on clone if tagged").For there will possibly be more flags in the sk_user_data field,this patch also refactor sk_user_data flags code to be more genericto improve its maintainability.

We should preventit by checking tfile->detached before queuing skb.Note this must be done under tfile->sk.sk_write_queue.lock because write()and ioctl(IFF_DETACH_QUEUE) can run concurrently. Otherwise, there wouldbe a small race window: write() ioctl(IFF_DETACH_QUEUE) `- tun_get_user `- __tun_detach |- if (tfile->detached) |- tun_disable_queue | `-> false | `- tfile->detached = tun | `- tun_queue_purge |- spin_lock_bh(&queue->lock) `- __skb_queue_tail(queue, skb)Another solution is to call tun_queue_purge() when closing andreattaching the detached queue, but it could paper over anotherproblems.

CVE-2024-57874 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:arm64: ptrace: fix partial SETREGSET for NT_ARM_TAGGED_ADDR_CTRLCurrently tagged_addr_ctrl_set() doesn't initialize the temporary 'ctrl'variable, and a SETREGSET call with a length of zero will leave thisuninitialized. Consequently tagged_addr_ctrl_set() will consume anarbitrary value, potentially leaking up to 64 bits of memory from thekernel stack. The read is limited to a specific slot on the stack, andthe issue does not provide a write mechanism.As set_tagged_addr_ctrl() only accepts values where bits [63:4] zero andrejects other values, a partial SETREGSET attempt will randomly succeedor fail depending on the value of the uninitialized value, and theexposure is significantly limited.Fix this by initializing the temporary value before copying the regsetfrom userspace, as for other regsets (e.g. NT_PRSTATUS, NT_PRFPREG,NT_ARM_SYSTEM_CALL). In the case of a zero-length write, the existingvalue of the tagged address ctrl will be retained.The NT_ARM_TAGGED_ADDR_CTRL regset is only visible in theuser_aarch64_view used by a native AArch64 task to manipulate anothernative AArch64 task. As get_tagged_addr_ctrl() only returns an errorvalue when called for a compat task, tagged_addr_ctrl_get() andtagged_addr_ctrl_set() should never observe an error value fromget_tagged_addr_ctrl(). Add a WARN_ON_ONCE() to both to indicate thatsuch an error would be unexpected, and error handlnig is not missing ineither case.

CVE-2025-38623 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: pnv_php: Fix surprise plug detection and recoveryThe existing PowerNV hotplug code did not handle surprise plug eventscorrectly, leading to a complete failure of the hotplug system after deviceremoval and a required reboot to detect new devices.This comes down to two issues: 1) When a device is surprise removed, often the bridge upstream port will cause a PE freeze on the PHB. If this freeze is not cleared, the MSI interrupts from the bridge hotplug notification logic will not be received by the kernel, stalling all plug events on all slots associated with the PE. 2) When a device is removed from a slot, regardless of surprise or programmatic removal, the associated PHB/PE ls left frozen. If this freeze is not cleared via a fundamental reset, skiboot is unable to clear the freeze and cannot retrain / rescan the slot. This also requires a reboot to clear the freeze and redetect the device in the slot.Issue the appropriate unfreeze and rescan commands on hotplug events,and don't oops on hotplug if pci_bus_to_OF_node() returns NULL.[bhelgaas: tidy comments]

CVE-2025-40105 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:vfs: Don't leak disconnected dentries on umountWhen user calls open_by_handle_at() on some inode that is not cached, wewill create disconnected dentry for it. If such dentry is a directory,exportfs_decode_fh_raw() will then try to connect this dentry to thedentry tree through reconnect_path(). It may happen for various reasons(such as corrupted fs or race with rename) that the call tolookup_one_unlocked() in reconnect_one() will fail to find the dentry weare trying to reconnect and instead create a new dentry under theparent. Now this dentry will not be marked as disconnected although theparent still may well be disconnected (at least in case thisinconsistency happened because the fs is corrupted and .. doesn't pointto the real parent directory). This creates inconsistency indisconnected flags but AFAICS it was mostly harmless. At least untilcommit f1ee616214cb ("VFS: don't keep disconnected dentries on d_anon")which removed adding of most disconnected dentries to sb->s_anon list.Thus after this commit cleanup of disconnected dentries implicitelyrelies on the fact that dput() will immediately reclaim such dentries.However when some leaf dentry isn't marked as disconnected, as in thescenario described above, the reclaim doesn't happen and the dentriesare "leaked". Memory reclaim can eventually reclaim them but otherwisethey stay in memory and if umount comes first, we hit infamous "Busyinodes after unmount" bug.

CVE-2025-40160 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:xen/events: Return -EEXIST for bound VIRQsChange find_virq() to return -EEXIST when a VIRQ is bound to adifferent CPU than the one passed in. With that, remove the BUG_ON()from bind_virq_to_irq() to propogate the error upwards.Some VIRQs are per-cpu, but others are per-domain or global. Those mustbe bound to CPU0 and can then migrate elsewhere. The lookup forper-domain and global will probably fail when migrated off CPU 0,especially when the current CPU is tracked. This now returns -EEXISTinstead of BUG_ON().A second call to bind a per-domain or global VIRQ is not expected, butmake it non-fatal to avoid trying to look up the irq, since we don'tknow which per_cpu(virq_to_irq) it will be in.

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

CVE-2024-51744 Severity: Moderate CVSS3 score: 3.1

Description: golang-jwt is a Go implementation of JSON Web Tokens. Unclear documentation of the error behavior in `ParseWithClaims` can lead to situation where users are potentially not checking errors in the way they should be. Especially, if a token is both expired and invalid, the errors returned by `ParseWithClaims` return both error codes. If users only check for the `jwt.ErrTokenExpired ` using `error.Is`, they will ignore the embedded `jwt.ErrTokenSignatureInvalid` and thus potentially accept invalid tokens. A fix has been back-ported with the error handling logic from the `v5` branch to the `v4` branch. In this logic, the `ParseWithClaims` function will immediately return in "dangerous" situations (e.g., an invalid signature), limiting the combined errors only to situations where the signature is valid, but further validation failed (e.g., if the signature is valid, but is expired AND has the wrong audience). This fix is part of the 4.5.1 release. We are aware that this changes the behaviour of an established function and is not 100 % backwards compatible, so updating to 4.5.1 might break your code. In case you cannot update to 4.5.0, please make sure that you are properly checking for all errors ("dangerous" ones first), so that you are not running in the case detailed above.

This means that when the socketis closed later, the socket teardown logic will think that there is apool attached to the socket and try to decrease the refcount again,leading to a refcount underflow.I chose this fix as it involved adding just a single line. Anotheroption would have been to move xp_get_pool() and the assignment ofxs->pool to after the if-statement and using xs_umem->pool instead ofxs->pool in the whole if-statement resulting in somewhat simpler code,but this would have led to much more churn in the code base perhapsmaking it harder to backport.

Description: In the Linux kernel, the following vulnerability has been resolved:netfs/fscache: Add a memory barrier for FSCACHE_VOLUME_CREATINGIn fscache_create_volume(), there is a missing memory barrier between thebit-clearing operation and the wake-up operation. This may cause asituation where, after a wake-up, the bit-clearing operation hasn't beendetected yet, leading to an indefinite wait. The triggering process is asfollows: [cookie1] [cookie2] [volume_work]fscache_perform_lookup fscache_create_volume fscache_perform_lookup fscache_create_volume fscache_create_volume_work cachefiles_acquire_volume clear_and_wake_up_bit test_and_set_bit test_and_set_bit goto maybe_wait goto no_waitIn the above process, cookie1 and cookie2 has the same volume. When cookie1enters the -no_wait- process, it will clear the bit and wake up the waitingprocess. If a barrier is missing, it may cause cookie2 to remain in the-wait- process indefinitely.In commit 3288666c7256 ("fscache: Use clear_and_wake_up_bit() infscache_create_volume_work()"), barriers were added to similar operationsin fscache_create_volume_work(), but fscache_create_volume() was missed.By combining the clear and wake operations into clear_and_wake_up_bit() tofix this issue.

CVE-2025-22021 Severity: Low CVSS3 score: 2.5

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: socket: Lookup orig tuple for IPv6 SNATnf_sk_lookup_slow_v4 does the conntrack lookup for IPv4 packets torestore the original 5-tuple in case of SNAT, to be able to find theright socket (if any). Then socket_match() can correctly check whetherthe socket was transparent.However, the IPv6 counterpart (nf_sk_lookup_slow_v6) lacks thisconntrack lookup, making xt_socket fail to match on the socket when thepacket was SNATed. Add the same logic to nf_sk_lookup_slow_v6.IPv6 SNAT is used in Kubernetes clusters for pod-to-world packets, aspods' addresses are in the fd00::/8 ULA subnet and need to be replacedwith the node's external address. Cilium leverages Envoy to enforce L7policies, and Envoy uses transparent sockets. Cilium inserts an iptablesprerouting rule that matches on `-m socket --transparent` and redirectsthe packets to localhost, but it fails to match SNATed IPv6 packets dueto that missing conntrack lookup.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:firmware: arm_scmi: Balance device refcount when destroying devicesUsing device_find_child() to lookup the proper SCMI device to destroycauses an unbalance in device refcount, since device_find_child() calls animplicit get_device(): this, in turns, inhibits the call of the providedrelease methods upon devices destruction.As a consequence, one of the structures that is not freed properly upondestruction is the internal struct device_private dev->p populated by thedrivers subsystem core.KMemleak detects this situation since loading/unloding some SCMI drivercauses related devices to be created/destroyed without calling anydevice_release method.unreferenced object 0xffff00000f583800 (size 512): comm "insmod", pid 227, jiffies 4294912190 hex dump (first 32 bytes): 00 00 00 00 ad 4e ad de ff ff ff ff 00 00 00 00 .....N.......... ff ff ff ff ff ff ff ff 60 36 1d 8a 00 80 ff ff ........`6...... backtrace (crc 114e2eed): kmemleak_alloc+0xbc/0xd8 __kmalloc_cache_noprof+0x2dc/0x398 device_add+0x954/0x12d0 device_register+0x28/0x40 __scmi_device_create.part.0+0x1bc/0x380 scmi_device_create+0x2d0/0x390 scmi_create_protocol_devices+0x74/0xf8 scmi_device_request_notifier+0x1f8/0x2a8 notifier_call_chain+0x110/0x3b0 blocking_notifier_call_chain+0x70/0xb0 scmi_driver_register+0x350/0x7f0 0xffff80000a3b3038 do_one_initcall+0x12c/0x730 do_init_module+0x1dc/0x640 load_module+0x4b20/0x5b70 init_module_from_file+0xec/0x158$ ./scripts/faddr2line ./vmlinux device_add+0x954/0x12d0device_add+0x954/0x12d0:kmalloc_noprof at include/linux/slab.h:901(inlined by) kzalloc_noprof at include/linux/slab.h:1037(inlined by) device_private_init at drivers/base/core.c:3510(inlined by) device_add at drivers/base/core.c:3561Balance device refcount by issuing a put_device() on devices found viadevice_find_child().

According to JFS layout description fromhttps://jfs.sourceforge.net/project/pub/jfslayout.pdf, inode types from 5 to15 are reserved for future extensions and should not be encountered on a validfilesystem. So add an extra check for valid inode type in 'copy_from_dinode()'.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: iwlwifi: fix debug actions orderThe order of actions taken for debug was implemented incorrectly.Now we implemented the dump split and do the FW reset only in themiddle of the dump (rather than the FW killing itself on error.)As a result, some of the actions taken when applying the configwill now crash the device, so we need to fix the order.

CVE-2023-53585 Severity: Low CVSS3 score: 2.3

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: reject unhashed sockets in bpf_sk_assignThe semantics for bpf_sk_assign are as follows: sk = some_lookup_func() bpf_sk_assign(skb, sk) bpf_sk_release(sk)That is, the sk is not consumed by bpf_sk_assign. The functiontherefore needs to make sure that sk lives long enough to beconsumed from __inet_lookup_skb. The path through the stack for aTCPv4 packet is roughly: netif_receive_skb_core: takes RCU read lock __netif_receive_skb_core: sch_handle_ingress: tcf_classify: bpf_sk_assign() deliver_ptype_list_skb: deliver_skb: ip_packet_type->func == ip_rcv: ip_rcv_core: ip_rcv_finish_core: dst_input: ip_local_deliver: ip_local_deliver_finish: ip_protocol_deliver_rcu: tcp_v4_rcv: __inet_lookup_skb: skb_steal_sockThe existing helper takes advantage of the fact that everythinghappens in the same RCU critical section: for sockets withSOCK_RCU_FREE set bpf_sk_assign never takes a reference.skb_steal_sock then checks SOCK_RCU_FREE again and does sock_putif necessary.This approach assumes that SOCK_RCU_FREE is never set on a skbetween bpf_sk_assign and skb_steal_sock, but this invariant isviolated by unhashed UDP sockets. A new UDP socket is createdin TCP_CLOSE state but without SOCK_RCU_FREE set. That flag is onlyadded in udp_lib_get_port() which happens when a socket is bound.When bpf_sk_assign was added it wasn't possible to access unhashedUDP sockets from BPF, so this wasn't a problem. This changedin commit 0c48eefae712 ("sock_map: Lift socket state restrictionfor datagram sockets"), but the helper wasn't adjusted accordingly.The following sequence of events will therefore lead to a refcountleak:1. Add socket(AF_INET, SOCK_DGRAM) to a sockmap.2. Pull socket out of sockmap and bpf_sk_assign it. Since SOCK_RCU_FREE is not set we increment the refcount.3. bind() or connect() the socket, setting SOCK_RCU_FREE.4. skb_steal_sock will now set refcounted = false due to SOCK_RCU_FREE.5. tcp_v4_rcv() skips sock_put().Fix the problem by rejecting unhashed sockets in bpf_sk_assign().This matches the behaviour of __inet_lookup_skb which is ultimatelythe goal of bpf_sk_assign().

CVE-2023-53243 Severity: Moderate CVSS3 score: 0.0

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: add handling for RAID1C23/DUP to btrfs_reduce_alloc_profileCallers of `btrfs_reduce_alloc_profile` expect it to return exactlyone allocation profile flag, and failing to do so may ultimatelyresult in a WARN_ON and remount-ro when allocating new blocks, likethe below transaction abort on 6.1.`btrfs_reduce_alloc_profile` has two ways of determining the profile,first it checks if a conversion balance is currently running anduses the profile we're converting to. If no balance is currentlyrunning, it returns the max-redundancy profile which at least oneblock in the selected block group has.This works by simply checking each known allocation profile bit inredundancy order. However, `btrfs_reduce_alloc_profile` has not beenupdated as new flags have been added - first with the `DUP` profileand later with the RAID1C34 profiles.Because of the way it checks, if we have blocks with differentprofiles and at least one is known, that profile will be selected.However, if none are known we may return a flag set with multipleallocation profiles set.This is currently only possible when a balance from one of the threeunhandled profiles to another of the unhandled profiles is canceledafter allocating at least one block using the new profile.In that case, a transaction abort like the below will occur and thefilesystem will need to be mounted with -o skip_balance to get itmounted rw again (but the balance cannot be resumed without asimilar abort).

Description: In the Linux kernel, the following vulnerability has been resolved:firmware: arm_ffa: Fix FFA device names for logical partitionsEach physical partition can provide multiple services each with UUID.Each such service can be presented as logical partition with a uniquecombination of VM ID and UUID. The number of distinct UUID in a systemwill be less than or equal to the number of logical partitions.However, currently it fails to register more than one logical partitionor service within a physical partition as the device name contains onlyVM ID while both VM ID and UUID are maintained in the partition information.The kernel complains with the below message: | sysfs: cannot create duplicate filename '/devices/arm-ffa-8001' | CPU: 1 PID: 1 Comm: swapper/0 Not tainted 6.3.0-rc7 #8 | Hardware name: FVP Base RevC (DT) | Call trace: | dump_backtrace+0xf8/0x118 | show_stack+0x18/0x24 | dump_stack_lvl+0x50/0x68 | dump_stack+0x18/0x24 | sysfs_create_dir_ns+0xe0/0x13c | kobject_add_internal+0x220/0x3d4 | kobject_add+0x94/0x100 | device_add+0x144/0x5d8 | device_register+0x20/0x30 | ffa_device_register+0x88/0xd8 | ffa_setup_partitions+0x108/0x1b8 | ffa_init+0x2ec/0x3a4 | do_one_initcall+0xcc/0x240 | do_initcall_level+0x8c/0xac | do_initcalls+0x54/0x94 | do_basic_setup+0x1c/0x28 | kernel_init_freeable+0x100/0x16c | kernel_init+0x20/0x1a0 | ret_from_fork+0x10/0x20 | kobject_add_internal failed for arm-ffa-8001 with -EEXIST, don't try to | register things with the same name in the same directory. | arm_ffa arm-ffa: unable to register device arm-ffa-8001 err=-17 | ARM FF-A: ffa_setup_partitions: failed to register partition ID 0x8001By virtue of being random enough to avoid collisions when generated in adistributed system, there is no way to compress UUID keys to the numberof bits required to identify each. We can eliminate '-' in the name butit is not worth eliminating 4 bytes and add unnecessary logic for doingthat. Also v1.0 doesn't provide the UUID of the partitions which makesit hard to use the same for the device name.So to keep it simple, let us alloc an ID using ida_alloc() and append thesame to "arm-ffa" to make up a unique device name. Also stash the id valuein ffa_dev to help freeing the ID later when the device is destroyed.

Description: In the Linux kernel, the following vulnerability has been resolved:start_kernel: Add __no_stack_protector function attributeBack during the discussion ofcommit a9a3ed1eff36 ("x86: Fix early boot crash on gcc-10, third try")we discussed the need for a function attribute to control the omissionof stack protectors on a per-function basis; at the time Clang hadsupport for no_stack_protector but GCC did not. This was fixed ingcc-11. Now that the function attribute is available, let's start usingit.Callers of boot_init_stack_canary need to use this function attributeunless they're compiled with -fno-stack-protector, otherwise the canarystored in the stack slot of the caller will differ upon the call toboot_init_stack_canary. This will lead to a call to __stack_chk_fail()then panic.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: drop unnecessary user-triggerable WARN_ONCE in verifierl logIt's trivial for user to trigger "verifier log line truncated" warning,as verifier has a fixed-sized buffer of 1024 bytes (as of now), and there are atleast two pieces of user-provided information that can be output throughthis buffer, and both can be arbitrarily sized by user: - BTF names; - BTF.ext source code lines strings.Verifier log buffer should be properly sized for typical verifier stateoutput. But it's sort-of expected that this buffer won't be long enoughin some circumstances. So let's drop the check. In any case code willwork correctly, at worst truncating a part of a single line output.

Note that while userspaceis capable of pending an asynchronous exception (SError, IRQ, or FIQ),it is still safe to retire the MMIO instruction in this case as (1) theyare by definition asynchronous, and (2) KVM relies on hardware supportfor pending/delivering these exceptions instead of the software statemachine for advancing PC.

CVE-2024-57913 Severity: Moderate CVSS3 score: 0.0

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: f_fs: Remove WARN_ON in functionfs_bindThis commit addresses an issue related to below kernel panic wherepanic_on_warn is enabled. It is caused by the unnecessary use of WARN_ONin functionsfs_bind, which easily leads to the following scenarios.1.adb_write in adbd 2. UDC write via configfs ================= =====================->usb_ffs_open_thread() ->UDC write ->open_functionfs() ->configfs_write_iter() ->adb_open() ->gadget_dev_desc_UDC_store() ->adb_write() ->usb_gadget_register_driver_owner ->driver_register()->StartMonitor() ->bus_add_driver() ->adb_read() ->gadget_bind_driver() ->configfs_composite_bind() ->usb_add_function()->open_functionfs() ->ffs_func_bind() ->adb_open() ->functionfs_bind() state !=FFS_ACTIVE>The adb_open, adb_read, and adb_write operations are invoked from thedaemon, but trying to bind the function is a process that is invoked byUDC write through configfs, which opens up the possibility of a racecondition between the two paths. In this race scenario, the kernel panicoccurs due to the WARN_ON from functionfs_bind when panic_on_warn isenabled.

CVE-2025-21960 Severity: Moderate CVSS3 score: 0.0

Description: In the Linux kernel, the following vulnerability has been resolved:eth: bnxt: do not update checksum in bnxt_xdp_build_skb()The bnxt_rx_pkt() updates ip_summed value at the end if checksum offloadis enabled.When the XDP-MB program is attached and it returns XDP_PASS, thebnxt_xdp_build_skb() is called to update skb_shared_info.The main purpose of bnxt_xdp_build_skb() is to update skb_shared_info,but it updates ip_summed value too if checksum offload is enabled.This is actually duplicate work.When the bnxt_rx_pkt() updates ip_summed value, it checks if ip_summedis CHECKSUM_NONE or not.It means that ip_summed should be CHECKSUM_NONE at this moment.But ip_summed may already be updated to CHECKSUM_UNNECESSARY in theXDP-MB-PASS path.So the by skb_checksum_none_assert() WARNS about it.This is duplicate work and updating ip_summed in thebnxt_xdp_build_skb() is not needed.Splat looks like:WARNING: CPU: 3 PID: 5782 at ./include/linux/skbuff.h:5155 bnxt_rx_pkt+0x479b/0x7610 [bnxt_en]Modules linked in: bnxt_re bnxt_en rdma_ucm rdma_cm iw_cm ib_cm ib_uverbs veth xt_nat xt_tcpudp xt_conntrack nft_chain_nat xt_MASQUERADE nf_]CPU: 3 UID: 0 PID: 5782 Comm: socat Tainted: G W 6.14.0-rc4+ #27Tainted: [W]=WARNHardware name: ASUS System Product Name/PRIME Z690-P D4, BIOS 0603 11/01/2021RIP: 0010:bnxt_rx_pkt+0x479b/0x7610 [bnxt_en]Code: 54 24 0c 4c 89 f1 4c 89 ff c1 ea 1f ff d3 0f 1f 00 49 89 c6 48 85 c0 0f 84 4c e5 ff ff 48 89 c7 e8 ca 3d a0 c8 e9 8f f4 ff ff <0f> 0b fRSP: 0018:ffff88881ba09928 EFLAGS: 00010202RAX: 0000000000000000 RBX: 00000000c7590303 RCX: 0000000000000000RDX: 1ffff1104e7d1610 RSI: 0000000000000001 RDI: ffff8881c91300b8RBP: ffff88881ba09b28 R08: ffff888273e8b0d0 R09: ffff888273e8b070R10: ffff888273e8b010 R11: ffff888278b0f000 R12: ffff888273e8b080R13: ffff8881c9130e00 R14: ffff8881505d3800 R15: ffff888273e8b000FS: 00007f5a2e7be080(0000) GS:ffff88881ba00000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007fff2e708ff8 CR3: 000000013e3b0000 CR4: 00000000007506f0PKRU: 55555554Call Trace: ? __warn+0xcd/0x2f0 ? bnxt_rx_pkt+0x479b/0x7610 ? report_bug+0x326/0x3c0 ? handle_bug+0x53/0xa0 ? exc_invalid_op+0x14/0x50 ? asm_exc_invalid_op+0x16/0x20 ? bnxt_rx_pkt+0x479b/0x7610 ? bnxt_rx_pkt+0x3e41/0x7610 ? __pfx_bnxt_rx_pkt+0x10/0x10 ? napi_complete_done+0x2cf/0x7d0 __bnxt_poll_work+0x4e8/0x1220 ? __pfx___bnxt_poll_work+0x10/0x10 ? __pfx_mark_lock.part.0+0x10/0x10 bnxt_poll_p5+0x36a/0xfa0 ? __pfx_bnxt_poll_p5+0x10/0x10 __napi_poll.constprop.0+0xa0/0x440 net_rx_action+0x899/0xd00...Following ping.py patch adds xdp-mb-pass case. so ping.py is goingto be able to reproduce this issue.

The segment list is then DMA'ed bythe FW and the length of the DMA is returned by FW. The driver thencopies this DMA'ed segment list to info->dest_buf.In some cases, this DMA length may exceed the info->dest_buf lengthand cause the above BUG condition. Fix it by capping the copylength to not exceed the length of info->dest_buf. The extraDMA data contains no useful information.This code path is shared for the HWRM_DBG_COREDUMP_LIST and theHWRM_DBG_COREDUMP_RETRIEVE FW commands. The buffering is differentfor these 2 FW commands. To simplify the logic, we need to movethe line to adjust the buffer length for HWRM_DBG_COREDUMP_RETRIEVEup, so that the new check to cap the copy length will work for bothcommands.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/nouveau: Fix WARN_ON in nouveau_fence_context_kill()Nouveau is mostly designed in a way that it's expected that fences onlyever get signaled through nouveau_fence_signal(). However, in at leastone other place, nouveau_fence_done(), can signal fences, too. If thathappens (race) a signaled fence remains in the pending list for a while,until it gets removed by nouveau_fence_update().Should nouveau_fence_context_kill() run in the meantime, this would bea bug because the function would attempt to set an error code on analready signaled fence.Have nouveau_fence_context_kill() check for a fence being signaled.

Disconnect ==========->dwc3_thread_interrupt ->dwc3_gadget_disconnect_interrupt ->dwc3_ep0_reset_state ->dwc3_ep0_end_control_data ->dwc3_send_gadget_ep_cmdIn the issue scenario, in Exynos platforms, we observed that controltransfers for the previous connect have not yet been completed and endtransfer command sent as a part of the disconnect sequence andprocessing of USB_ENDPOINT_HALT feature request from the host timeout.This maybe an expected scenario since the controller is processing EPcommands sent as a part of the previous connect. It maybe better toremove WARN_ON in all places where device endpoint commands are sent toavoid unnecessary kernel panic due to warn.

Description: In the Linux kernel, the following vulnerability has been resolved:ixgbevf: fix mailbox API compatibility by negotiating supported featuresThere was backward compatibility in the terms of mailbox API. Variousdrivers from various OSes supporting 10G adapters from Intel portfoliocould easily negotiate mailbox API.This convention has been broken since introducing API 1.4.Commit 0062e7cc955e ("ixgbevf: add VF IPsec offload code") added supportfor IPSec which is specific only for the kernel ixgbe driver. None of therest of the Intel 10G PF/VF drivers supports it. And actually lack ofsupport was not included in the IPSec implementation - there were no suchcode paths. No possibility to negotiate support for the feature wasintroduced along with introduction of the feature itself.Commit 339f28964147 ("ixgbevf: Add support for new mailbox communicationbetween PF and VF") increasing API version to 1.5 did the same - itintroduced code supported specifically by the PF ESX driver. It altered APIversion for the VF driver in the same time not touching the versiondefined for the PF ixgbe driver. It led to additional discrepancies,as the code provided within API 1.6 cannot be supported for Linux ixgbedriver as it causes crashes.The issue was noticed some time ago and mitigated by Jake within the commitd0725312adf5 ("ixgbevf: stop attempting IPSEC offload on Mailbox API 1.5").As a result we have regression for IPsec support and after increasing APIto version 1.6 ixgbevf driver stopped to support ESX MBX.To fix this mess add new mailbox op asking PF driver about supportedfeatures. Basing on a response determine whether to set support for IPSecand ESX-specific enhanced mailbox.New mailbox op, for compatibility purposes, must be added within new APIrevision, as API version of OOT PF & VF drivers is already increased to1.6 and doesn't incorporate features negotiate op.Features negotiation mechanism gives possibility to be extended with newfeatures when needed in the future.

CVE-2026-23463 Severity: Moderate CVSS3 score: 0.0

Description: In the Linux kernel, the following vulnerability has been resolved:soc: fsl: qbman: fix race condition in qman_destroy_fqWhen QMAN_FQ_FLAG_DYNAMIC_FQID is set, there's a race condition betweenfq_table[fq->idx] state and freeing/allocating from the pool andWARN_ON(fq_table[fq->idx]) in qman_create_fq() gets triggered.Indeed, we can have: Thread A Thread B qman_destroy_fq() qman_create_fq() qman_release_fqid() qman_shutdown_fq() gen_pool_free() -- At this point, the fqid is available again -- qman_alloc_fqid() -- so, we can get the just-freed fqid in thread B -- fq->fqid = fqid; fq->idx = fqid * 2; WARN_ON(fq_table[fq->idx]); fq_table[fq->idx] = fq; fq_table[fq->idx] = NULL;And adding some logs between qman_release_fqid() andfq_table[fq->idx] = NULL makes the WARN_ON() trigger a lot more.To prevent that, ensure that fq_table[fq->idx] is set to NULL beforegen_pool_free() is called by using smp_wmb().
