CVE-2020-14343 Severity: Important CVSS3 score: 8.8

Description: A vulnerability was discovered in the PyYAML library in versions before 5.4, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this flaw. This flaw allows an attacker to execute arbitrary code on the system by abusing the python/object/new constructor. This flaw is due to an incomplete fix for CVE-2020-1747.

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.

Packages affected:

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.

CVE-2026-31629 Severity: Important CVSS3 score: 8.8

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.

CVE-2026-31709 Severity: Important CVSS3 score: 8.8

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.

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: xt_tcpmss: check remaining length before reading optlenQuoting reporter: In net/netfilter/xt_tcpmss.c (lines 53-68), the TCP option parser reads op[i+1] directly without validating the remaining option length. If the last byte of the option field is not EOL/NOP (0/1), the code attempts to index op[i+1]. In the case where i + 1 == optlen, this causes an out-of-bounds read, accessing memory past the optlen boundary (either reading beyond the stack buffer _opt or the following payload).

CVE-2026-8177 Severity: Important CVSS3 score: 8.2

Description: XML::LibXML versions through 2.0210 for Perl read out-of-bounds heap memory when parsing XML node names containing truncated UTF-8 byte sequences.A node name ending in the middle of a multi byte UTF-8 sequence causes the parser to read past the end of the input string into adjacent heap memory.Any Perl process that passes attacker controlled strings to XML::LibXML's DOM node-name methods can reach this path on the default API. The likely consequence is a crash, causing denial of service.

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.

CVE-2022-48991 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:mm/khugepaged: invoke MMU notifiers in shmem/file collapse pathsAny codepath that zaps page table entries must invoke MMU notifiers toensure that secondary MMUs (like KVM) don't keep accessing pages whicharen't mapped anymore. Secondary MMUs don't hold their own references topages that are mirrored over, so failing to notify them can lead to pageuse-after-free.I'm marking this as addressing an issue introduced in commit f3f0e1d2150b("khugepaged: add support of collapse for tmpfs/shmem pages"), but most ofthe security impact of this only came in commit 27e1f8273113 ("khugepaged:enable collapse pmd for pte-mapped THP"), which actually omitted flushesfor the removal of present PTEs, not just for the removal of empty pagetables.

CVE-2024-26584 Severity: Important CVSS3 score: 7.8

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

The pipe_buf_operations for thesebuffers used .get = generic_pipe_buf_get, which only increments the pagereference count when tee(2) duplicates a pipe buffer. The smc_spd_privpointer itself was not handled, so after tee() both the original and thecloned pipe_buffer share the same smc_spd_priv *.When both pipes are subsequently released, smc_rx_pipe_buf_release() iscalled twice against the same object: 1st call: kfree(priv) sock_put(sk) smc_rx_update_cons() [correct] 2nd call: kfree(priv) sock_put(sk) smc_rx_update_cons() [UAF]KASAN reports a slab-use-after-free in smc_rx_pipe_buf_release(), whichthen escalates to a NULL-pointer dereference and kernel panic viasmc_rx_update_consumer() when it chases the freed priv->smc pointer: BUG: KASAN: slab-use-after-free in smc_rx_pipe_buf_release+0x78/0x2a0 Read of size 8 at addr ffff888004a45740 by task smc_splice_tee_/74 Call Trace: dump_stack_lvl+0x53/0x70 print_report+0xce/0x650 kasan_report+0xc6/0x100 smc_rx_pipe_buf_release+0x78/0x2a0 free_pipe_info+0xd4/0x130 pipe_release+0x142/0x160 __fput+0x1c6/0x490 __x64_sys_close+0x4f/0x90 do_syscall_64+0xa6/0x1a0 entry_SYSCALL_64_after_hwframe+0x77/0x7f BUG: kernel NULL pointer dereference, address: 0000000000000020 RIP: 0010:smc_rx_update_consumer+0x8d/0x350 Call Trace: smc_rx_pipe_buf_release+0x121/0x2a0 free_pipe_info+0xd4/0x130 pipe_release+0x142/0x160 __fput+0x1c6/0x490 __x64_sys_close+0x4f/0x90 do_syscall_64+0xa6/0x1a0 entry_SYSCALL_64_after_hwframe+0x77/0x7f Kernel panic - not syncing: Fatal exceptionBeyond the memory-safety problem, duplicating an SMC splice buffer issemantically questionable: smc_rx_update_cons() would advance theconsumer cursor twice for the same data, corrupting receive-windowaccounting. A refcount on smc_spd_priv could fix the double-free, butthe cursor-accounting issue would still need to be addressed separately.The .get callback is invoked by both tee(2) and splice_pipe_to_pipe()for partial transfers; both will now return -EFAULT. Users who needto duplicate SMC socket data must use a copy-based read path.

CVE-2026-43437 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: pcm: fix use-after-free on linked stream runtime in snd_pcm_drain()In the drain loop, the local variable 'runtime' is reassigned to alinked stream's runtime (runtime = s->runtime at line 2157). Afterreleasing the stream lock at line 2169, the code accessesruntime->no_period_wakeup, runtime->rate, and runtime->buffer_size(lines 2170-2178) - all referencing the linked stream's runtime withoutany lock or refcount protecting its lifetime.A concurrent close() on the linked stream's fd triggerssnd_pcm_release_substream() -> snd_pcm_drop() -> pcm_release_private()-> snd_pcm_unlink() -> snd_pcm_detach_substream() -> kfree(runtime).No synchronization prevents kfree(runtime) from completing while thedrain path dereferences the stale pointer.Fix by caching the needed runtime fields (no_period_wakeup, rate,buffer_size) into local variables while still holding the stream lock,and using the cached values after the lock is released.

CVE-2026-43497 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:fbdev: udlfb: add vm_ops to dlfb_ops_mmap to prevent use-after-freedlfb_ops_mmap() uses remap_pfn_range() to map vmalloc framebuffer pagesto userspace but sets no vm_ops on the VMA. This means the kernel cannottrack active mmaps. When dlfb_realloc_framebuffer() replaces the backingbuffer via FBIOPUT_VSCREENINFO, existing mmap PTEs are not invalidated.On USB disconnect, dlfb_ops_destroy() calls vfree() on the old pageswhile userspace PTEs still reference them, resulting in a use-after-free:the process retains read/write access to freed kernel pages.Add vm_operations_struct with open/close callbacks that maintain anatomic mmap_count on struct dlfb_data. In dlfb_realloc_framebuffer(),check mmap_count and return -EBUSY if the buffer is currently mapped,preventing buffer replacement while userspace holds stale PTEs.Tested with PoC using dummy_hcd + raw_gadget USB device emulation.

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: require a full NFS mode SID before reading mode bitsparse_dacl() treats an ACE SID matching sid_unix_NFS_mode as an NFSmode SID and reads sid.sub_auth[2] to recover the mode bits.That assumes the ACE carries three subauthorities, but compare_sids()only compares min(a, b) subauthorities. A malicious server can returnan ACE with num_subauth = 2 and sub_auth[] = {88, 3}, which stillmatches sid_unix_NFS_mode and then drives the sub_auth[2] read fourbytes past the end of the ACE.Require num_subauth >= 3 before treating the ACE as an NFS mode SID.This keeps the fix local to the special-SID mode path without changingcompare_sids() semantics for the rest of cifsacl.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: L2CAP: Fix use-after-free in l2cap_unregister_userAfter commit ab4eedb790ca ("Bluetooth: L2CAP: Fix corrupted list inhci_chan_del"), l2cap_conn_del() uses conn->lock to protect access toconn->users. However, l2cap_register_user() and l2cap_unregister_user()don't use conn->lock, creating a race condition where these functions canaccess conn->users and conn->hchan concurrently with l2cap_conn_del().This can lead to use-after-free and list corruption bugs, as reportedby syzbot.Fix this by changing l2cap_register_user() and l2cap_unregister_user()to use conn->lock instead of hci_dev_lock(), ensuring consistent lockingfor the l2cap_conn structure.

CVE-2026-31649 Severity: Important CVSS3 score: 7.5

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

CVE-2026-33846 Severity: Important CVSS3 score: 7.5

Description: A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption.

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).

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: fix in-place encryption corruption in SMB2_write()SMB2_write() places write payload in iov[1..n] as part of rq_iov.smb3_init_transform_rq() pointer-shares rq_iov, so crypt_message()encrypts iov[1] in-place, replacing the original plaintext withciphertext. On a replayable error, the retry sends the same iov[1]which now contains ciphertext instead of the original data,resulting in corruption.The corruption is most likely to be observed when connections areunstable, as reconnects trigger write retries that re-send thealready-encrypted data.This affects SFU mknod, MF symlinks, etc. On kernels before6.10 (prior to the netfs conversion), sync writes also usedthis path and were similarly affected. The async write pathwasn't unaffected as it uses rq_iter which gets deep-copied.Fix by moving the write payload into rq_iter via iov_iter_kvec(),so smb3_init_transform_rq() deep-copies it before encryption.

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

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

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

CVE-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-2026-29518 Severity: Important CVSS3 score: 7.0

Description: Rsync versions before 3.4.3 contain a time-of-check to time-of-use (TOCTOU) race condition in daemon file handling that allows attackers to redirect file writes outside intended directories by replacing parent directory components with symbolic links. Attackers with write access to a module path can exploit this race condition to create or overwrite arbitrary files, potentially modifying sensitive system files and achieving privilege escalation when the daemon runs with elevated privileges. This vulnerability can only be triggered if the chroot setting is false.

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-2026-31504 Severity: Important CVSS3 score: 7.0

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-2026-31588 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-2026-31700 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.

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.

Moreover, sincefore200e_reset() could prevent further interrupts or data transfers,the tasklet_kill() should be placed after fore200e_reset() to preventthe tasklet from being rescheduled in fore200e_interrupt(). Finally,it only needs to do tasklet_kill() when the fore200e state is greaterthan or equal to FORE200E_STATE_IRQ, since tasklets are uninitializedin earlier states.

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved: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:ocfs2: validate inline data i_size during inode readWhen reading an inode from disk, ocfs2_validate_inode_block() performsvarious sanity checks but does not validate the size of inline data. Ifthe filesystem is corrupted, an inode's i_size can exceed the actualinline data capacity (id_count).This causes ocfs2_dir_foreach_blk_id() to iterate beyond the inline databuffer, triggering a use-after-free when accessing directory entries fromfreed memory.In the syzbot report: - i_size was 1099511627576 bytes (~1TB) - Actual inline data capacity (id_count) is typically <256 bytes - A garbage rec_len (54648) caused ctx->pos to jump out of bounds - This triggered a UAF in ocfs2_check_dir_entry()Fix by adding a validation check in ocfs2_validate_inode_block() to ensureinodes with inline data have i_size <= id_count. This catches thecorruption early during inode read and prevents all downstream code fromoperating on invalid data.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix out-of-bounds write in trie_get_next_key()trie_get_next_key() allocates a node stack with size trie->max_prefixlen,while it writes (trie->max_prefixlen + 1) nodes to the stack when it hasfull paths from the root to leaves. For example, consider a trie withmax_prefixlen is 8, and the nodes with key 0x00/0, 0x00/1, 0x00/2, ...0x00/8 inserted. Subsequent calls to trie_get_next_key with _key with.prefixlen = 8 make 9 nodes be written on the node stack with size 8.

CVE-2025-46836 Severity: Moderate CVSS3 score: 6.6

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

CVE-2026-43359 Severity: Moderate CVSS3 score: 6.6

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix transaction abort on set received ioctl due to item overflowIf the set received ioctl fails due to an item overflow when attempting toadd the BTRFS_UUID_KEY_RECEIVED_SUBVOL we have to abort the transactionsince we did some metadata updates before.This means that if a user calls this ioctl with the same received UUIDfield for a lot of subvolumes, we will hit the overflow, trigger thetransaction abort and turn the filesystem into RO mode. A malicious usercould exploit this, and this ioctl does not even requires that a userhas admin privileges (CAP_SYS_ADMIN), only that he/she owns the subvolume.Fix this by doing an early check for item overflow before starting atransaction. This is also race safe because we are holding the subvol_semsemaphore in exclusive (write) mode.A test case for fstests will follow soon.

CVE-2026-45130 Severity: Moderate CVSS3 score: 6.6

Description: Vim is an open source, command line text editor. Prior to version 9.2.0450, a heap buffer overflow exists in read_compound() in src/spellfile.c when loading a crafted spell file (.spl) with UTF-8 encoding active. An attacker-controlled length field in the spell file's compound section overflows a 32-bit signed integer multiplication, causing a small buffer to be allocated for a write loop that runs many iterations, overflowing the heap. Because the 'spelllang' option can be set from a modeline, a text file modeline can trigger spell file loading if a malicious .spl file has been planted on the runtimepath. This issue has been patched in version 9.2.0450.

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.

Description: A vulnerability has been found in the CPython `venv` module and CLI where path names provided when creating a virtual environment were not quoted properly, allowing the creator to inject commands into virtual environment "activation" scripts (ie "source venv/bin/activate"). This means that attacker-controlled virtual environments are able to run commands when the virtual environment is activated. Virtual environments which are not created by an attacker or which aren't activated before being used (ie "./venv/bin/python") are not affected.

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

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

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

CVE-2026-31498 Severity: Moderate CVSS3 score: 6.5

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(). Also add a pdu_len zero check inl2cap_segment_sdu() as a safeguard.

CVE-2026-31607 Severity: Moderate CVSS3 score: 6.5

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.

Description: In the Linux kernel, the following vulnerability has been resolved:batman-adv: reject oversized global TT response buffersbatadv_tt_prepare_tvlv_global_data() builds the allocation length for aglobal TT response in 16-bit temporaries. When a remote originatoradvertises a large enough global TT, the TT payload length plus the VLANheader offset can exceed 65535 and wrap before kmalloc().The full-table response path still uses the original TT payload length whenit fills tt_change, so the wrapped allocation is too small andbatadv_tt_prepare_tvlv_global_data() writes past the end of the heap objectbefore the later packet-size check runs.Fix this by rejecting TT responses whose TVLV value length cannot fit inthe 16-bit TVLV payload length field.

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

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

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

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

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-2026-31502 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.

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved: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:wifi: radiotap: reject radiotap with unknown bitsThe radiotap parser is currently only used with the radiotapnamespace (not with vendor namespaces), but if the undefinedfield 18 is used, the alignment/size is unknown as well. Inthis case, iterator->_next_ns_data isn't initialized (it'sonly set for skipping vendor namespaces), and syzbot pointsout that we later compare against this uninitialized value.Fix this by moving the rejection of unknown radiotap fieldsdown to after the in-namespace lookup, so it will really useiterator->_next_ns_data only for vendor namespaces, even incase undefined fields are present.

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-2026-43073 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:x86-64: rename misleadingly named '__copy_user_nocache()' functionThis function was a masterclass in bad naming, for various historicalreasons.It claimed to be a non-cached user copy. It is literally _neither_ ofthose things. It's a specialty memory copy routine that usesnon-temporal stores for the destination (but not the source), and thatdoes exception handling for both source and destination accesses.Also note that while it works for unaligned targets, any unaligned parts(whether at beginning or end) will not use non-temporal stores, sinceonly words and quadwords can be non-temporal on x86.The exception handling means that it _can_ be used for user spaceaccesses, but not on its own - it needs all the normal "start user spaceaccess" logic around it.But typically the user space access would be the source, not thenon-temporal destination. That was the original intention of this,where the destination was some fragile persistent memory target thatneeded non-temporal stores in order to catch machine check exceptionssynchronously and deal with them gracefully.Thus that non-descriptive name: one use case was to copy from user spaceinto a non-cached kernel buffer. However, the existing users are a mixof that intended use-case, and a couple of random drivers that just didthis as a performance tweak.Some of those random drivers then actively misused the user copyingversion (with STAC/CLAC and all) to do kernel copies without ever evencaring about the exception handling, _just_ for the non-temporaldestination.Rename it as a first small step to actually make it halfway sane, andchange the prototype to be more normal: it doesn't take a user pointerunless the caller has done the proper conversion, and the argument sizeis the full size_t (it still won't actually copy more than 4GB in onego, but there's also no reason to silently truncate the size argument inthe caller).Finally, use this now sanely named function in the NTB code, whichmis-used a user copy version (with STAC/CLAC and all) of this interfacedespite it not actually being a user copy at all.

CVE-2026-43158 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:xfs: fix freemap adjustments when adding xattrs to leaf blocksxfs/592 and xfs/794 both trip this assertion in the leaf block freemapadjustment code after ~20 minutes of running on my test VMs: ASSERT(ichdr->firstused >= ichdr->count * sizeof(xfs_attr_leaf_entry_t) + xfs_attr3_leaf_hdr_size(leaf));Upon enabling quite a lot more debugging code, I narrowed this down tofsstress trying to set a local extended attribute with namelen=3 andvaluelen=71. This results in an entry size of 80 bytes.At the start of xfs_attr3_leaf_add_work, the freemap looks like this:i 0 base 448 size 0 rhs 448 count 46i 1 base 388 size 132 rhs 448 count 46i 2 base 2120 size 4 rhs 448 count 46firstused = 520where "rhs" is the first byte past the end of the leaf entry array.This is inconsistent -- the entries array ends at byte 448, butfreemap[1] says there's free space starting at byte 388!By the end of the function, the freemap is in worse shape:i 0 base 456 size 0 rhs 456 count 47i 1 base 388 size 52 rhs 456 count 47i 2 base 2120 size 4 rhs 456 count 47firstused = 440Important note: 388 is not aligned with the entries array element sizeof 8 bytes.Based on the incorrect freemap, the name area starts at byte 440, whichis below the end of the entries array! That's why the assertiontriggers and the filesystem shuts down.How did we end up here? First, recall from the previous patch that thefreemap array in an xattr leaf block is not intended to be acomprehensive map of all free space in the leaf block. In other words,it's perfectly legal to have a leaf block with: * 376 bytes in use by the entries array * freemap[0] has [base = 376, size = 8] * freemap[1] has [base = 388, size = 1500] * the space between 376 and 388 is free, but the freemap stopped tracking that some time agoIf we add one xattr, the entries array grows to 384 bytes, andfreemap[0] becomes [base = 384, size = 0]. So far, so good. But if weadd a second xattr, the entries array grows to 392 bytes, and freemap[0]gets pushed up to [base = 392, size = 0]. This is bad, becausefreemap[1] hasn't been updated, and now the entries array and the freespace claim the same space.The fix here is to adjust all freemap entries so that none of themcollide with the entries array. Note that this fix relies on commit2a2b5932db6758 ("xfs: fix attr leaf header freemap.size underflow") andthe previous patch that resets zero length freemap entries to havebase = 0.

CVE-2026-43187 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:xfs: delete attr leaf freemap entries when emptyBack in commit 2a2b5932db6758 ("xfs: fix attr leaf header freemap.sizeunderflow"), Brian Foster observed that it's possible for a smallfreemap at the end of the end of the xattr entries array to experiencea size underflow when subtracting the space consumed by an expansion ofthe entries array. There are only three freemap entries, which meansthat it is not a complete index of all free space in the leaf block.This code can leave behind a zero-length freemap entry with a nonzerobase. Subsequent setxattr operations can increase the base up to thepoint that it overlaps with another freemap entry. This isn't in and ofitself a problem because the code in _leaf_add that finds free spaceignores any freemap entry with zero size.However, there's another bug in the freemap update code in _leaf_add,which is that it fails to update a freemap entry that begins midwaythrough the xattr entry that was just appended to the array. That canresult in the freemap containing two entries with the same base butdifferent sizes (0 for the "pushed-up" entry, nonzero for the entrythat's actually tracking free space). A subsequent _leaf_add can thenallocate xattr namevalue entries on top of the entries array, leading todata loss. But fixing that is for later.For now, eliminate the possibility of confusion by zeroing out the baseof any freemap entry that has zero size. Because the freemap is notintended to be a complete index of free space, a subsequent failure tofind any free space for a new xattr will trigger block compaction, whichregenerates the freemap.It looks like this bug has been in the codebase for quite a long time.

CVE-2026-43250 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:usb: chipidea: udc: fix DMA and SG cleanup in _ep_nuke()The ChipIdea UDC driver can encounter "not page aligned sg buffer"errors when a USB device is reconnected after being disconnectedduring an active transfer. This occurs because _ep_nuke() returnsrequests to the gadget layer without properly unmapping DMA buffersor cleaning up scatter-gather bounce buffers.Root cause:When a disconnect happens during a multi-segment DMA transfer, therequest's num_mapped_sgs field and sgt.sgl pointer remain set withstale values. The request is returned to the gadget driver with status-ESHUTDOWN but still has active DMA state. If the gadget driver reusesthis request on reconnect without reinitializing it, the stale DMAstate causes _hardware_enqueue() to skip DMA mapping (seeing non-zeronum_mapped_sgs) and attempt to use freed/invalid DMA addresses,leading to alignment errors and potential memory corruption.The normal completion path via _hardware_dequeue() properly callsusb_gadget_unmap_request_by_dev() and sglist_do_debounce() beforereturning the request. The _ep_nuke() path must do the same cleanupto ensure requests are returned in a clean, reusable state.Fix:Add DMA unmapping and bounce buffer cleanup to _ep_nuke() to mirrorthe cleanup sequence in _hardware_dequeue():- Call usb_gadget_unmap_request_by_dev() if num_mapped_sgs is set- Call sglist_do_debounce() with copy=false if bounce buffer existsThis ensures that when requests are returned due to endpoint shutdown,they don't retain stale DMA mappings. The 'false' parameter tosglist_do_debounce() prevents copying data back (appropriate forshutdown path where transfer was aborted).

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-2026-23448 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:net: usb: cdc_ncm: add ndpoffset to NDP16 nframes bounds checkcdc_ncm_rx_verify_ndp16() validates that the NDP header and its DPEentries fit within the skb. 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.

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").

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: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-2026-31778 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-2024-47742 Severity: Moderate CVSS3 score: 6.0

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

CVE-2019-1549 Severity: Moderate CVSS3 score: 5.9

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

Description: In the Linux kernel, the following vulnerability has been resolved:tcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV socketsTCP_SYN_RECV state is really special, it is only used bycross-syn connections, mostly used by fuzzers.In the following crash [1], syzbot managed to trigger a divideby zero in tcp_rcv_space_adjust()A socket makes the following state transitions,without ever calling tcp_init_transfer(),meaning tcp_init_buffer_space() is also not called.

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

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

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

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

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

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

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

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

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

CVE-2026-6357 Severity: Moderate CVSS3 score: 5.8

Description: pip prior to version 26.1 would run self-update check functionality after installing wheel files which required importing well-known Python modules names. These module imports were intentionally deferred to increase startup time of the pip CLI. The patch changes self-update functionality to run before wheels are installed to prevent newly-installed modules from being imported shortly after the installation of a wheel package. Users should still review package contents prior to installation.

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-2025-55158 Severity: Moderate CVSS3 score: 5.6

Description: Vim is an open source, command line text editor. In versions from 9.1.1231 to before 9.1.1406, when processing nested tuples during Vim9 script import operations, an error during evaluation can trigger a double-free in Vim's internal typed value (typval_T) management. Specifically, the clear_tv() function may attempt to free memory that has already been deallocated, due to improper lifetime handling in the handle_import / ex_import code paths. The vulnerability can only be triggered if a user explicitly opens and executes a specially crafted Vim script. This issue has been patched in version 9.1.1406.

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.

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

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

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

Description: Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters (instead of using a named curve). In those cases it is possible that such a group does not have the cofactor present. This can occur even where all the parameters match a known named curve. If such a curve is used then OpenSSL falls back to non-side channel resistant code paths which may result in full key recovery during an ECDSA signature operation. In order to be vulnerable an attacker would have to have the ability to time the creation of a large number of signatures where explicit parameters with no co-factor present are in use by an application using libcrypto. For the avoidance of doubt libssl is not vulnerable because explicit parameters are never used. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL 1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s).

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

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

Fix it by using dst_hold_safe() andchecking if a reference was actually taken before setting the dst.[1] dmesg WARN_ON log and following refcnt errors WARNING: CPU: 5 PID: 38 at include/net/dst.h:230 br_handle_egress_vlan_tunnel+0x10b/0x134 [bridge] Modules linked in: 8021q garp mrp bridge stp llc bonding ipv6 virtio_net CPU: 5 PID: 38 Comm: ksoftirqd/5 Kdump: loaded Tainted: G W 5.13.0-rc3+ #360 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33 04/01/2014 RIP: 0010:br_handle_egress_vlan_tunnel+0x10b/0x134 [bridge] Code: e8 85 bc 01 e1 45 84 f6 74 90 45 31 f6 85 db 48 c7 c7 a0 02 19 a0 41 0f 94 c6 31 c9 31 d2 44 89 f6 e8 64 bc 01 e1 85 db 75 02 <0f> 0b 31 c9 31 d2 44 89 f6 48 c7 c7 70 02 19 a0 e8 4b bc 01 e1 49 RSP: 0018:ffff8881003d39e8 EFLAGS: 00010246 RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 0000000000000001 RDI: ffffffffa01902a0 RBP: ffff8881040c6700 R08: 0000000000000000 R09: 0000000000000001 R10: 2ce93d0054fe0d00 R11: 54fe0d00000e0000 R12: ffff888109515000 R13: 0000000000000000 R14: 0000000000000001 R15: 0000000000000401 FS: 0000000000000000(0000) GS:ffff88822bf40000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f42ba70f030 CR3: 0000000109926000 CR4: 00000000000006e0 Call Trace: br_handle_vlan+0xbc/0xca [bridge] __br_forward+0x23/0x164 [bridge] deliver_clone+0x41/0x48 [bridge] br_handle_frame_finish+0x36f/0x3aa [bridge] ? skb_dst+0x2e/0x38 [bridge] ? br_handle_ingress_vlan_tunnel+0x3e/0x1c8 [bridge] ? br_handle_frame_finish+0x3aa/0x3aa [bridge] br_handle_frame+0x2c3/0x377 [bridge] ? __skb_pull+0x33/0x51 ? vlan_do_receive+0x4f/0x36a ? br_handle_frame_finish+0x3aa/0x3aa [bridge] __netif_receive_skb_core+0x539/0x7c6 ? __list_del_entry_valid+0x16e/0x1c2 __netif_receive_skb_list_core+0x6d/0xd6 netif_receive_skb_list_internal+0x1d9/0x1fa gro_normal_list+0x22/0x3e dev_gro_receive+0x55b/0x600 ? detach_buf_split+0x58/0x140 napi_gro_receive+0x94/0x12e virtnet_poll+0x15d/0x315 [virtio_net] __napi_poll+0x2c/0x1c9 net_rx_action+0xe6/0x1fb __do_softirq+0x115/0x2d8 run_ksoftirqd+0x18/0x20 smpboot_thread_fn+0x183/0x19c ? smpboot_unregister_percpu_thread+0x66/0x66 kthread+0x10a/0x10f ? kthread_mod_delayed_work+0xb6/0xb6 ret_from_fork+0x22/0x30 ---[ end trace 49f61b07f775fd2b ]--- dst_release: dst:00000000c02d677a refcnt:-1 dst_release underflow

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

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

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

The problem was in wrong mutex_init() location.Previous mutex_init(&state->msg_lock) call was in ->init() function, butdvb_usbv2_init() has this order of calls: dvb_usbv2_init() dvb_usbv2_adapter_init() dvb_usbv2_adapter_frontend_init() props->frontend_attach() props->init()Since mxl111sf_* devices call mxl111sf_ctrl_msg() in ->frontend_attach()internally we need to initialize state->msg_lock beforefrontend_attach(). To achieve it, ->probe() call added to all mxl111sf_*devices, which will simply initiaize mutex.

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

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

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

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

CVE-2022-48953 Severity: Moderate CVSS3 score: 5.5

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

Description: In the Linux kernel, the following vulnerability has been resolved:net: xfrm: unexport __init-annotated xfrm4_protocol_init()EXPORT_SYMBOL and __init is a bad combination because the .init.textsection is freed up after the initialization. Hence, modules cannotuse symbols annotated __init. The access to a freed symbol may end upwith kernel panic.modpost used to detect it, but it has been broken for a decade.Recently, I fixed modpost so it started to warn it again, then thisshowed up in linux-next builds.There are two ways to fix it: - Remove __init - Remove EXPORT_SYMBOLI chose the latter for this case because the only in-tree call-site,net/ipv4/xfrm4_policy.c is never compiled as modular.(CONFIG_XFRM is boolean)

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

Description: In the Linux kernel, the following vulnerability has been resolved:media: dvb-usb-v2: af9035: Fix null-ptr-deref in af9035_i2c_master_xferIn af9035_i2c_master_xfer, msg is controlled by user.

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

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

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

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

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

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

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

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

Fill_meta_index() is called to allocate (via empty_meta_index()) and fill a metadata index. It however suffers a data read error and aborts, invalidating the newly returned empty metadata index. It does this by setting the inode number of the index to zero, which means unused (zero is not a valid inode number).2. When fill_meta_index() is subsequently called again on another read operation, locate_meta_index() returns the previous index because it matches the inode number of 0. Because this index has been returned it is expected to have been filled, and because it hasn't been, an out of bounds access is performed.This patch adds a sanity check which checks that the inode numberis not zero when the inode is created and returns -EINVAL if it is.[phillip@squashfs.org.uk: whitespace fix]

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:irqchip/gic-v3-its: Prevent double free on errorThe error handling path in its_vpe_irq_domain_alloc() causes a double freewhen its_vpe_init() fails after successfully allocating at least oneinterrupt. This happens because its_vpe_irq_domain_free() frees theinterrupts along with the area bitmap and the vprop_page andits_vpe_irq_domain_alloc() subsequently frees the area bitmap and thevprop_page again.Fix this by unconditionally invoking its_vpe_irq_domain_free() whichhandles all cases correctly and by removing the bitmap/vprop_page freeingfrom its_vpe_irq_domain_alloc().[ tglx: Massaged change log ]

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.

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:gpio: prevent potential speculation leaks in gpio_device_get_desc()Userspace may trigger a speculative read of an address outside the gpiodescriptor array.Users can do that by calling gpio_ioctl() with an offset out of range.Offset is copied from user and then used as an array index to getthe gpio descriptor without sanitization in gpio_device_get_desc().This change ensures that the offset is sanitized by usingarray_index_nospec() to mitigate any possibility of speculativeinformation leaks.This bug was discovered and resolved using Coverity Static AnalysisSecurity Testing (SAST) by Synopsys, Inc.

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

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

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

CVE-2024-46744 Severity: Moderate CVSS3 score: 5.5

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

Additionally, such request may put undue burden on thesystem which will try to free a lot of memory for a bogus request.Fix it by limiting allowed number of slots to 100. This can easilybe extended if we see devices that can track more than 100 contacts.

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

[0]The repro calls connect() to vxcan1, removes vxcan1, and callsconnect() with ifindex == 0.Calling connect() for a BCM socket allocates a proc entry.Then, bcm_sk(sk)->bound is set to 1 to prevent further connect().However, removing the bound device resets bcm_sk(sk)->bound to 0in bcm_notify().The 2nd connect() tries to allocate a proc entry with the samename and sets NULL to bcm_sk(sk)->bcm_proc_read, leaking theoriginal proc entry.Since the proc entry is available only for connect()ed sockets,let's clean up the entry when the bound netdev is unregistered.[0]:proc_dir_entry 'can-bcm/2456' already registeredWARNING: CPU: 1 PID: 394 at fs/proc/generic.c:376 proc_register+0x645/0x8f0 fs/proc/generic.c:375Modules linked in:CPU: 1 PID: 394 Comm: syz-executor403 Not tainted 6.10.0-rc7-g852e42cc2dd4Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014RIP: 0010:proc_register+0x645/0x8f0 fs/proc/generic.c:375Code: 00 00 00 00 00 48 85 ed 0f 85 97 02 00 00 4d 85 f6 0f 85 9f 02 00 00 48 c7 c7 9b cb cf 87 48 89 de 4c 89 fa e8 1c 6f eb fe 90 <0f> 0b 90 90 48 c7 c7 98 37 99 89 e8 cb 7e 22 05 bb 00 00 00 10 48RSP: 0018:ffa0000000cd7c30 EFLAGS: 00010246RAX: 9e129be1950f0200 RBX: ff1100011b51582c RCX: ff1100011857cd80RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000002RBP: 0000000000000000 R08: ffd400000000000f R09: ff1100013e78cac0R10: ffac800000cd7980 R11: ff1100013e12b1f0 R12: 0000000000000000R13: 0000000000000000 R14: 0000000000000000 R15: ff1100011a99a2ecFS: 00007fbd7086f740(0000) GS:ff1100013fd00000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00000000200071c0 CR3: 0000000118556004 CR4: 0000000000771ef0DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000DR3: 0000000000000000 DR6: 00000000fffe07f0 DR7: 0000000000000400PKRU: 55555554Call Trace: proc_create_net_single+0x144/0x210 fs/proc/proc_net.c:220 bcm_connect+0x472/0x840 net/can/bcm.c:1673 __sys_connect_file net/socket.c:2049 [inline] __sys_connect+0x5d2/0x690 net/socket.c:2066 __do_sys_connect net/socket.c:2076 [inline] __se_sys_connect net/socket.c:2073 [inline] __x64_sys_connect+0x8f/0x100 net/socket.c:2073 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xd9/0x1c0 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x4b/0x53RIP: 0033:0x7fbd708b0e5dCode: ff c3 66 2e 0f 1f 84 00 00 00 00 00 90 f3 0f 1e fa 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d 73 9f 1b 00 f7 d8 64 89 01 48RSP: 002b:00007fff8cd33f08 EFLAGS: 00000246 ORIG_RAX: 000000000000002aRAX: ffffffffffffffda RBX: 0000000000000003 RCX: 00007fbd708b0e5dRDX: 0000000000000010 RSI: 0000000020000040 RDI: 0000000000000003RBP: 0000000000000000 R08: 0000000000000040 R09: 0000000000000040R10: 0000000000000040 R11: 0000000000000246 R12: 00007fff8cd34098R13: 0000000000401280 R14: 0000000000406de8 R15: 00007fbd70ab9000 remove_proc_entry: removing non-empty directory 'net/can-bcm', leaking at least '2456'

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

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

In do_walk_down() we catch this case and handle it correctly,however we return -EIO, which -EUCLEAN is a more appropriate error code.Finally in walk_up_proc we have the same BUG_ON(refs == 0), so convertthat to proper error handling.

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

So it onlysupports the AC+DC brightness entries and mute.Check that the SINF array has a minimum size which covers all AC+DCbrightness entries and refuse to load if the SINF array is smaller.For higher SINF indexes hide the sysfs attributes when the SINF arraydoes not contain an entry for that attribute, avoiding show()/store()accessing the array out of bounds and add bounds checking to the probe()and resume() code accessing these.

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

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: update orig_path in ext4_find_extent()In ext4_find_extent(), if the path is not big enough, we free it and set*orig_path to NULL. But after reallocating and successfully initializingthe path, we don't update *orig_path, in which case the caller gets avalid path but a NULL ppath, and this may cause a NULL pointer dereferenceor a path memory leak. For example:ext4_split_extent path = *ppath = 2000 ext4_find_extent if (depth > path[0].p_maxdepth) kfree(path = 2000); *orig_path = path = NULL; path = kcalloc() = 3000 ext4_split_extent_at(*ppath = NULL) path = *ppath; ex = path[depth].p_ext; // NULL pointer dereference!==================================================================BUG: kernel NULL pointer dereference, address: 0000000000000010CPU: 6 UID: 0 PID: 576 Comm: fsstress Not tainted 6.11.0-rc2-dirty #847RIP: 0010:ext4_split_extent_at+0x6d/0x560Call Trace: ext4_split_extent.isra.0+0xcb/0x1b0 ext4_ext_convert_to_initialized+0x168/0x6c0 ext4_ext_handle_unwritten_extents+0x325/0x4d0 ext4_ext_map_blocks+0x520/0xdb0 ext4_map_blocks+0x2b0/0x690 ext4_iomap_begin+0x20e/0x2c0[...]==================================================================Therefore, *orig_path is updated when the extent lookup succeeds, so thatthe caller can safely use path or *ppath.

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:jbd2: stop waiting for space when jbd2_cleanup_journal_tail() returns errorIn __jbd2_log_wait_for_space(), we might call jbd2_cleanup_journal_tail()to recover some journal space. But if an error occurs while executingjbd2_cleanup_journal_tail() (e.g., an EIO), we don't stop waiting for freespace right away, we try other branches, and if j_committing_transactionis NULL (i.e., the tid is 0), we will get the following complain:============================================JBD2: I/O error when updating journal superblock for sdd-8.__jbd2_log_wait_for_space: needed 256 blocks and only had 217 space available__jbd2_log_wait_for_space: no way to get more journal space in sdd-8------------[ cut here ]------------WARNING: CPU: 2 PID: 139804 at fs/jbd2/checkpoint.c:109 __jbd2_log_wait_for_space+0x251/0x2e0Modules linked in:CPU: 2 PID: 139804 Comm: kworker/u8:3 Not tainted 6.6.0+ #1RIP: 0010:__jbd2_log_wait_for_space+0x251/0x2e0Call Trace: add_transaction_credits+0x5d1/0x5e0 start_this_handle+0x1ef/0x6a0 jbd2__journal_start+0x18b/0x340 ext4_dirty_inode+0x5d/0xb0 __mark_inode_dirty+0xe4/0x5d0 generic_update_time+0x60/0x70[...]============================================So only if jbd2_cleanup_journal_tail() returns 1, i.e., there is nothing toclean up at the moment, continue to try to reclaim free space in other ways.Note that this fix relies on commit 6f6a6fda2945 ("jbd2: fix ocfs2 corruptwhen updating journal superblock fails") to make jbd2_cleanup_journal_tailreturn the correct error code.

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

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

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

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

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

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

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

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

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

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

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-2025-38721 Severity: Moderate CVSS3 score: 5.5

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-2025-39684 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-2025-40100 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!

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.

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

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

CVE-2025-68211 Severity: Moderate CVSS3 score: 5.5

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix racy bitfield write in btrfs_clear_space_info_full()From the memory-barriers.txt document regarding memory barrier orderingguarantees: (*) These guarantees do not apply to bitfields, because compilers often generate code to modify these using non-atomic read-modify-write sequences. Do not attempt to use bitfields to synchronize parallel algorithms. (*) Even in cases where bitfields are protected by locks, all fields in a given bitfield must be protected by one lock. If two fields in a given bitfield are protected by different locks, the compiler's non-atomic read-modify-write sequences can cause an update to one field to corrupt the value of an adjacent field.btrfs_space_info has a bitfield sharing an underlying word consisting ofthe fields full, chunk_alloc, and flush:struct btrfs_space_info { struct btrfs_fs_info * fs_info; /* 0 8 */ struct btrfs_space_info * parent; /* 8 8 */ ... int clamp; /* 172 4 */ unsigned int full:1; /* 176: 0 4 */ unsigned int chunk_alloc:1; /* 176: 1 4 */ unsigned int flush:1; /* 176: 2 4 */ ...Therefore, to be safe from parallel read-modify-writes losing a write toone of the bitfield members protected by a lock, all writes to all thebitfields must use the lock. They almost universally do, except forbtrfs_clear_space_info_full() which iterates over the space_infos andwrites out found->full = 0 without a lock.Imagine that we have one thread completing a transaction in which wefinished deleting a block_group and are thus callingbtrfs_clear_space_info_full() while simultaneously the data reclaimticket infrastructure is running do_async_reclaim_data_space(): T1 T2btrfs_commit_transaction btrfs_clear_space_info_full data_sinfo->full = 0 READ: full:0, chunk_alloc:0, flush:1 do_async_reclaim_data_space(data_sinfo) spin_lock(&space_info->lock); if(list_empty(tickets)) space_info->flush = 0; READ: full: 0, chunk_alloc:0, flush:1 MOD/WRITE: full: 0, chunk_alloc:0, flush:0 spin_unlock(&space_info->lock); return; MOD/WRITE: full:0, chunk_alloc:0, flush:1and now data_sinfo->flush is 1 but the reclaim worker has exited. Thisbreaks the invariant that flush is 0 iff there is no work queued orrunning. Once this invariant is violated, future allocations that gointo __reserve_bytes() will add tickets to space_info->tickets but willsee space_info->flush is set to 1 and not queue the work. After this,they will block forever on the resulting ticket, as it is now impossibleto kick the worker again.I also confirmed by looking at the assembly of the affected kernel thatit is doing RMW operations. For example, to set the flush (3rd) bit to 0,the assembly is: andb $0xfb,0x60(%rbx)and similarly for setting the full (1st) bit to 0: andb $0xfe,-0x20(%rax)So I think this is really a bug on practical systems. I have observeda number of systems in this exact state, but am currently unable toreproduce it.Rather than leaving this footgun lying around for the future, takeadvantage of the fact that there is room in the struct anyway, and thatit is already quite large and simply change the three bitfield members tobools. This avoids writes to space_info->full having any effect on---truncated---

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

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:ice: Fix memory leak in ice_set_ringparam()In ice_set_ringparam, tx_rings and xdp_rings are allocated beforerx_rings. If the allocation of rx_rings fails, the code jumps tothe done label leaking both tx_rings and xdp_rings. Furthermore, ifthe setup of an individual Rx ring fails during the loop, the code jumpsto the free_tx label which releases tx_rings but leaks xdp_rings.Fix this by introducing a free_xdp label and updating the error paths toensure both xdp_rings and tx_rings are properly freed if rx_ringsallocation or setup fails.Compile tested only. Issue found using a prototype static analysis tooland code review.

CVE-2026-25645 Severity: Moderate CVSS3 score: 5.5

Description: Requests is a HTTP library. Prior to version 2.33.0, the `requests.utils.extract_zipped_paths()` utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validation. A local attacker with write access to the temp directory could pre-create a malicious file that would be loaded in place of the legitimate one. Standard usage of the Requests library is not affected by this vulnerability. Only applications that call `extract_zipped_paths()` directly are impacted. Starting in version 2.33.0, the library extracts files to a non-deterministic location. If developers are unable to upgrade, they can set `TMPDIR` in their environment to a directory with restricted write access.

On version v249 and older the effect is not an assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is not possible as the safety check causes an assert instead. This IPC call was added in v239, so versions older than that are not affected.

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-2026-31486 Severity: Moderate CVSS3 score: 5.5

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

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---

CVE-2026-31576 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:media: hackrf: fix to not free memory after the device is registered in hackrf_probe()In hackrf driver, the following race condition occurs:``` CPU0 CPU1hackrf_probe() kzalloc(); // alloc hackrf_dev .... v4l2_device_register(); .... fd = sys_open("/path/to/dev"); // open hackrf fd .... v4l2_device_unregister(); .... kfree(); // free hackrf_dev .... sys_ioctl(fd, ...); v4l2_ioctl(); video_is_registered() // UAF!! .... sys_close(fd); v4l2_release() // UAF!! hackrf_video_release() kfree(); // DFB!!```When a V4L2 or video device is unregistered, the device node is removed sonew open() calls are blocked.However, file descriptors that are already open-and any in-flight I/O-donot terminate immediately; they remain valid until the last reference isdropped and the driver's release() is invoked.Therefore, freeing device memory on the error path after hackrf_probe()has registered dev it will lead to a race to use-after-free vuln, sincethose already-open handles haven't been released yet.And since release() free memory too, race to use-after-free anddouble-free vuln occur.To prevent this, if device is registered from probe(), it should bemodified to free memory only through release() rather than callingkfree() directly.

CVE-2026-31578 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:media: as102: fix to not free memory after the device is registered in as102_usb_probe()In as102_usb driver, the following race condition occurs:``` CPU0 CPU1as102_usb_probe() kzalloc(); // alloc as102_dev_t .... usb_register_dev(); fd = sys_open("/path/to/dev"); // open as102 fd .... usb_deregister_dev(); .... kfree(); // free as102_dev_t .... sys_close(fd); as102_release() // UAF!! as102_usb_release() kfree(); // DFB!!```When a USB character device registered with usb_register_dev() is laterunregistered (via usb_deregister_dev() or disconnect), the device node isremoved so new open() calls fail. 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.

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

But until commita166563e7ec37 ("arm64: mm: support large block mapping whenrodata=full") large leaf mappings were never made invalid in this way.It turns out various parts of the code base are not equipped to handleinvalid large leaf mappings (in the way they are currently encoded) andI've observed a kernel panic while booting a realm guest on aBBML2_NOABORT system as a result:[ 15.432706] software IO TLB: Memory encryption is active and system is using DMA bounce buffers[ 15.476896] Unable to handle kernel paging request at virtual address ffff000019600000[ 15.513762] Mem abort info:[ 15.527245] ESR = 0x0000000096000046[ 15.548553] EC = 0x25: DABT (current EL), IL = 32 bits[ 15.572146] SET = 0, FnV = 0[ 15.592141] EA = 0, S1PTW = 0[ 15.612694] FSC = 0x06: level 2 translation fault[ 15.640644] Data abort info:[ 15.661983] ISV = 0, ISS = 0x00000046, ISS2 = 0x00000000[ 15.694875] CM = 0, WnR = 1, TnD = 0, TagAccess = 0[ 15.723740] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0[ 15.755776] swapper pgtable: 4k pages, 48-bit VAs, pgdp=0000000081f3f000[ 15.800410] [ffff000019600000] pgd=0000000000000000, p4d=180000009ffff403, pud=180000009fffe403, pmd=00e8000199600704[ 15.855046] Internal error: Oops: 0000000096000046 [#1] SMP[ 15.886394] Modules linked in:[ 15.900029] CPU: 0 UID: 0 PID: 1 Comm: swapper/0 Not tainted 7.0.0-rc4-dirty #4 PREEMPT[ 15.935258] Hardware name: linux,dummy-virt (DT)[ 15.955612] pstate: 21400005 (nzCv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--)[ 15.986009] pc : __pi_memcpy_generic+0x128/0x22c[ 16.006163] lr : swiotlb_bounce+0xf4/0x158[ 16.024145] sp : ffff80008000b8f0[ 16.038896] x29: ffff80008000b8f0 x28: 0000000000000000 x27: 0000000000000000[ 16.069953] x26: ffffb3976d261ba8 x25: 0000000000000000 x24: ffff000019600000[ 16.100876] x23: 0000000000000001 x22: ffff0000043430d0 x21: 0000000000007ff0[ 16.131946] x20: 0000000084570010 x19: 0000000000000000 x18: ffff00001ffe3fcc[ 16.163073] x17: 0000000000000000 x16: 00000000003fffff x15: 646e612065766974[ 16.194131] x14: 0000000000000000 x13: 0000000000000000 x12: 0000000000000000[ 16.225059] x11: 0000000000000000 x10: 0000000000000010 x9 : 0000000000000018[ 16.256113] x8 : 0000000000000018 x7 : 0000000000000000 x6 : 0000000000000000[ 16.287203] x5 : ffff000019607ff0 x4 : ffff000004578000 x3 : ffff000019600000[ 16.318145] x2 : 0000000000007ff0 x1 : ffff000004570010 x0 : ffff000019600000[ 16.349071] Call trace:[ 16.360143] __pi_memcpy_generic+0x128/0x22c (P)[ 16.380310] swiotlb_tbl_map_single+0x154/0x2b4[ 16.400282] swiotlb_map+0x5c/0x228[ 16.415984] dma_map_phys+0x244/0x2b8[ 16.432199] dma_map_page_attrs+0x44/0x58[ 16.449782] virtqueue_map_page_attrs+0x38/0x44[ 16.469596] virtqueue_map_single_attrs+0xc0/0x130[ 16.490509] virtnet_rq_alloc.isra.0+0xa4/0x1fc[ 16.510355] try_fill_recv+0x2a4/0x584[ 16.526989] virtnet_open+0xd4/0x238[ 16.542775] __dev_open+0x110/0x24c[ 16.558280] __dev_change_flags+0x194/0x20c[ 16.576879] netif_change_flags+0x24/0x6c[ 16.594489] dev_change_flags+0x48/0x7c[ 16.611462] ip_auto_config+0x258/0x1114[ 16.628727] do_one_initcall+0x80/0x1c8[ 16.645590] kernel_init_freeable+0x208/0x2f0[ 16.664917] kernel_init+0x24/0x1e0[ 16.680295] ret_from_fork+0x10/0x20[ 16.696369] Code: 927cec03 cb0e0021 8b0e0042 a9411c26 (a900340c)[ 16.723106] ---[ end trace 0000000000000000 ]---[ 16.752866] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b[ 16.792556] Kernel Offset: 0x3396ea200000 from 0xffff8000800000---truncated---

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

While the XDR path (rxrpc_preparse_xdr_rxkad()) correctlyvalidates the ticket length against AFSTOKEN_RK_TIX_MAX, the non-XDRpath fails to do so.This allows an unprivileged user to provide a very large ticket length.When this key is later read via rxrpc_read(), the totaltoken size (toksize) calculation results in a value that exceedsAFSTOKEN_LENGTH_MAX, triggering a WARN_ON().[ 2001.302904] WARNING: CPU: 2 PID: 2108 at net/rxrpc/key.c:778 rxrpc_read+0x109/0x5c0 [rxrpc]Fix this by adding a check in the non-XDR parsing path of rxrpc_preparse()to ensure the ticket length does not exceed AFSTOKEN_RK_TIX_MAX,bringing it into parity with the XDR parsing logic.

As a result, the reference count to`gdev->dev` isn't dropped on the error handling paths.Drop the reference on errors.Also reorder the instructions to make the error handling simpler.Now gpiochip_add_data_with_key() roughly looks like: >>> Some memory allocation. Go to ERR ZONE 1 on errors. >>> device_initialize(). gpiodev_release() takes over the responsibility for freeing the resources of `gdev->dev`. The subsequent error handling paths shouldn't go through ERR ZONE 1 again which leads to double free. >>> Some initialization mainly on `gdev`. >>> The rest of initialization.

CVE-2026-31749 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: ni_atmio16d: Fix invalid clean-up after failed attachIf the driver's COMEDI "attach" handler function (`atmio16d_attach()`)returns an error, the COMEDI core will call the driver's "detach"handler function (`atmio16d_detach()`) to clean up. This calls`reset_atmio16d()` unconditionally, but depending on where the erroroccurred in the attach handler, the device may not have beensufficiently initialized to call `reset_atmio16d()`. It uses`dev->iobase` as the I/O port base address and `dev->private` as thepointer to the COMEDI device's private data structure. `dev->iobase`may still be set to its initial value of 0, which would result inundesired writes to low I/O port addresses. `dev->private` may still be`NULL`, which would result in null pointer dereferences.Fix `atmio16d_detach()` by checking that `dev->private` is valid(non-null) before calling `reset_atmio16d()`. This implies that`dev->iobase` was set correctly since that is set up before`dev->private`.

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: dt2815: add hardware detection to prevent crashThe dt2815 driver crashes when attached to I/O ports without actualhardware present. This occurs because syzkaller or users can attachthe driver to arbitrary I/O addresses via COMEDI_DEVCONFIG ioctl.When no hardware exists at the specified port, inb() operations return0xff (floating bus), but outb() operations can trigger page faults dueto undefined behavior, especially under race conditions: BUG: unable to handle page fault for address: 000000007fffff90 #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page RIP: 0010:dt2815_attach+0x6e0/0x1110Add hardware detection by reading the status register before attemptingany write operations. If the read returns 0xff, assume no hardware ispresent and fail the attach with -ENODEV. This prevents crashes fromoutb() operations on non-existent hardware.

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

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

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

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.

Thesame invalid metadata can also trigger the corresponding BUG_ON() inbtrfs_drop_snapshot().[FIX]Fix this by validating the root_item invariant in tree-checker whenreading root items from disk: if drop_progress.objectid is non-zero,drop_level must also be non-zero. Reject such malformed metadata with-EUCLEAN before it reaches merge_reloc_root() or btrfs_drop_snapshot()and triggers the BUG_ON.After the fix, the same corruption is correctly rejected by tree-checkerand the BUG_ON is no longer triggered.

Description: In the Linux kernel, the following vulnerability has been resolved:HID: core: Mitigate potential OOB by removing bogus memset()The memset() in hid_report_raw_event() has the good intention ofclearing out bogus data by zeroing the area from the end of the incomingdata string to the assumed end of the buffer. However, as we havepreviously seen, doing so can easily result in OOB reads and writes inthe subsequent thread of execution.The current suggestion from one of the HID maintainers is to remove thememset() and simply return if the incoming event buffer size is notlarge enough to fill the associated report.Suggested-by Benjamin Tissoires [bentiss: changed the return value]

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: ctnetlink: ensure safe access to master conntrackHolding reference on the expectation is not sufficient, the masterconntrack object can just go away, making exp->master invalid.To access exp->master safely:- Grab the nf_conntrack_expect_lock, this gets serialized with clean_from_lists() which also holds this lock when the master conntrack goes away.- Hold reference on master conntrack via nf_conntrack_find_get(). Not so easy since the master tuple to look up for the master conntrack is not available in the existing problematic paths.This patch goes for extending the nf_conntrack_expect_lock sectionto address this issue for simplicity, in the cases that are describedbelow this is just slightly extending the lock section.The add expectation command already holds a reference to the masterconntrack from ctnetlink_create_expect().However, the delete expectation command needs to grab the spinlockbefore looking up for the expectation. Expand the existing spinlocksection to address this to cover the expectation lookup. Note that,the nf_ct_expect_iterate_net() calls already grabs the spinlock whileiterating over the expectation table, which is correct.The get expectation command needs to grab the spinlock to ensure masterconntrack does not go away. This also expands the existing spinlocksection to cover the expectation lookup too. I needed to move thenetlink skb allocation out of the spinlock to keep it GFP_KERNEL.For the expectation events, the IPEXP_DESTROY event is already deliveredunder the spinlock, just move the delivery of IPEXP_NEW under thespinlock too because the master conntrack event cache is reached throughexp->master.While at it, add lockdep notations to help identify what codepaths needto grab the spinlock.

CVE-2026-43194 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: consume xmit errors of GSO framesudpgro_frglist.sh and udpgro_bench.sh are the flakiest testscurrently in NIPA. They fail in the same exact way, TCP GROtest stalls occasionally and the test gets killed after 10min.These tests use veth to simulate GRO. They attach a trivial("return XDP_PASS;") XDP program to the veth to force TSO offand NAPI on.Digging into the failure mode we can see that the connectionis completely stuck after a burst of drops. The sender's snd_nxtis at sequence number N [1], but the receiver claims to havereceived (rcv_nxt) up to N + 3 * MSS [2]. Last piece of the puzzleis that senders rtx queue is not empty (let's say the block inthe rtx queue is at sequence number N - 4 * MSS [3]).In this state, sender sends a retransmission from the rtx queuewith a single segment, and sequence numbers N-4*MSS:N-3*MSS [3].Receiver sees it and responds with an ACK all the way up toN + 3 * MSS [2]. But sender will reject this ack as TCP_ACK_UNSENT_DATAbecause it has no recollection of ever sending data that far out [1].And we are stuck.The root cause is the mess of the xmit return codes. veth returnsan error when it can't xmit a frame. We end up with a loss eventlike this: ------------------------------------------------- | GSO super frame 1 | GSO super frame 2 | |-----------------------------------------------| | seg | seg | seg | seg | seg | seg | seg | seg | | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | ------------------------------------------------- x ok ok | ok ok ok \\ snd_nxt"x" means packet lost by veth, and "ok" means it went thru.Since veth has TSO disabled in this test it sees individual segments.Segment 1 is on the retransmit queue and will be resent.So why did the sender not advance snd_nxt even tho it clearly didsend up to seg 8? tcp_write_xmit() interprets the return codefrom the core to mean that data has not been sent at all. SinceTCP deals with GSO super frames, not individual segment the cruxof the problem is that loss of a single segment can be interpretedas loss of all. TCP only sees the last return code for the lastsegment of the GSO frame (in <> brackets in the diagram above).Of course for the problem to occur we need a setup or a devicewithout a Qdisc. Otherwise Qdisc layer disconnects the protocollayer from the device errors completely.We have multiple ways to fix this. 1) make veth not return an error when it lost a packet. While this is what I think we did in the past, the issue keeps reappearing and it's annoying to debug. The game of whack a mole is not great. 2) fix the damn return codes We only talk about NETDEV_TX_OK and NETDEV_TX_BUSY in the documentation, so maybe we should make the return code from ndo_start_xmit() a boolean. I like that the most, but perhaps some ancient, not-really-networking protocol would suffer. 3) make TCP ignore the errors It is not entirely clear to me what benefit TCP gets from interpreting the result of ip_queue_xmit()? Specifically once the connection is established and we're pushing data - packet loss is just packet loss? 4) this fix Ignore the rc in the Qdisc-less+GSO case, since it's unreliable. We already always return OK in the TCQ_F_CAN_BYPASS case. In the Qdisc-less case let's be a bit more conservative and only mask the GSO errors. This path is taken by non-IP-"networks" like CAN, MCTP etc, so we could regress some ancient thing. This is the simplest, but also maybe the hackiest fix?Similar fix has been proposed by Eric in the past but never committedbecause original reporter was working with an OOT driver and wasn'tproviding feedback (see Link).

The lock mustnot be taken in IRQ context, only softirq is okay. A few drivers receivethe timestamp via a dedicated interrupt and complete the TX timestampfrom that handler. This will lead to a deadlock if the lock is alreadywrite-locked on the same CPU.Taking the lock can be avoided. The socket (pointed by the skb) willremain valid until the skb is released. The ->sk_socket and ->filemember will be set to NULL once the user closes the socket which mayhappen before the timestamp arrives.If we happen to observe the pointer while the socket is closing butbefore the pointer is set to NULL then we may use it because bothpointer (and the file's cred member) are RCU freed.Drop the lock. Use READ_ONCE() to obtain the individual pointer. Add amatching WRITE_ONCE() where the pointer are cleared.

Description: In the Linux kernel, the following vulnerability has been resolved:clocksource/drivers/sh_tmu: Always leave device running after probeThe TMU device can be used as both a clocksource and a clockeventprovider. The driver tries to be smart and power itself on and off, aswell as enabling and disabling its clock when it's not in operation.This behavior is slightly altered if the TMU is used as an earlyplatform device in which case the device is left powered on after probe,but the clock is still enabled and disabled at runtime.This has worked for a long time, but recent improvements in PREEMPT_RTand PROVE_LOCKING have highlighted an issue. As the TMU registers itselfas a clockevent provider, clockevents_register_device(), it needs to useraw spinlocks internally as this is the context of which the clockeventframework interacts with the TMU driver. However in the context ofholding a raw spinlock the TMU driver can't really manage its powerstate or clock with calls to pm_runtime_*() and clk_*() as these callsend up in other platform drivers using regular spinlocks to controlpower and clocks.This mix of spinlock contexts trips a lockdep warning. ============================= [ BUG: Invalid wait context ] 6.18.0-arm64-renesas-09926-gee959e7c5e34 #1 Not tainted ----------------------------- swapper/0/0 is trying to lock: ffff000008c9e180 (&dev->power.lock){-...}-{3:3}, at: __pm_runtime_resume+0x38/0x88 other info that might help us debug this: context-{5:5} 1 lock held by swapper/0/0: ccree e6601000.crypto: ARM CryptoCell 630P Driver: HW version 0xAF400001/0xDCC63000, Driver version 5.0 #0: ffff8000817ec298 ccree e6601000.crypto: ARM ccree device initialized (tick_broadcast_lock){-...}-{2:2}, at: __tick_broadcast_oneshot_control+0xa4/0x3a8 stack backtrace: CPU: 0 UID: 0 PID: 0 Comm: swapper/0 Not tainted 6.18.0-arm64-renesas-09926-gee959e7c5e34 #1 PREEMPT Hardware name: Renesas Salvator-X 2nd version board based on r8a77965 (DT) Call trace: show_stack+0x14/0x1c (C) dump_stack_lvl+0x6c/0x90 dump_stack+0x14/0x1c __lock_acquire+0x904/0x1584 lock_acquire+0x220/0x34c _raw_spin_lock_irqsave+0x58/0x80 __pm_runtime_resume+0x38/0x88 sh_tmu_clock_event_set_oneshot+0x84/0xd4 clockevents_switch_state+0xfc/0x13c tick_broadcast_set_event+0x30/0xa4 __tick_broadcast_oneshot_control+0x1e0/0x3a8 tick_broadcast_oneshot_control+0x30/0x40 cpuidle_enter_state+0x40c/0x680 cpuidle_enter+0x30/0x40 do_idle+0x1f4/0x280 cpu_startup_entry+0x34/0x40 kernel_init+0x0/0x130 do_one_initcall+0x0/0x230 __primary_switched+0x88/0x90For non-PREEMPT_RT builds this is not really an issue, but forPREEMPT_RT builds where normal spinlocks can sleep this might be anissue.

CVE-2026-43244 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:kcm: fix zero-frag skb in frag_list on partial sendmsg errorSyzkaller reported a warning in kcm_write_msgs() when processing amessage with a zero-fragment skb in the frag_list.When kcm_sendmsg() fills MAX_SKB_FRAGS fragments in the current skb,it allocates a new skb (tskb) and links it into the frag_list beforecopying data. If the copy subsequently fails (e.g. -EFAULT fromuser memory), tskb remains in the frag_list with zero fragments: head skb (msg being assembled, NOT yet in sk_write_queue) +-----------+ | frags[17] | (MAX_SKB_FRAGS, all filled with data) | frag_list-+--> tskb +-----------+ +----------+ | frags[0] | (empty! copy failed before filling) +----------+For SOCK_SEQPACKET with partial data already copied, the error pathsaves this message via partial_message for later completion. ForSOCK_SEQPACKET, sock_write_iter() automatically sets MSG_EOR, so asubsequent zero-length write(fd, NULL, 0) completes the message andqueues it to sk_write_queue. kcm_write_msgs() then walks thefrag_list and hits: WARN_ON(!skb_shinfo(skb)->nr_frags)TCP has a similar pattern where skbs are enqueued before data copyand cleaned up on failure via tcp_remove_empty_skb(). KCM wasmissing the equivalent cleanup.Fix this by tracking the predecessor skb (frag_prev) when allocatinga new frag_list entry. On error, if the tail skb has zero frags,use frag_prev to unlink and free it in O(1) without walking thesingly-linked frag_list. frag_prev is safe to dereference becausethe entire message chain is only held locally (or in kcm->seq_skb)and is not added to sk_write_queue until MSG_EOR, so the send pathcannot free it underneath us.Also change the WARN_ON to WARN_ON_ONCE to avoid flooding the logif the condition is somehow hit repeatedly.There are currently no KCM selftests in the kernel tree; a simplereproducer is available at [1].[1] https://gist.github.com/mrpre/a94d431c757e8d6f168f4dd1a3749daa

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-audio: Add sanity check for OOB writes at silencingAt silencing the playback URB packets in the implicit fb mode beforethe actual playback, we blindly assume that the received packets fitwith the buffer size. But when the setup in the capture streamdiffers from the playback stream (e.g. due to the USB core limitationof max packet size), such an inconsistency may lead to OOB writes tothe buffer, resulting in a crash.For addressing it, add a sanity check of the transfer buffer size atprepare_silent_urb(), and stop the data copy if the received dataoverflows. Also, report back the transfer error properly from there,too.Note that this doesn't fix the root cause of the playback erroritself, but this merely covers the kernel Oops.

CVE-2026-43309 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:md raid: fix hang when stopping arrays with metadata through dm-raidWhen using device-mapper's dm-raid target, stopping a RAID array can causethe system to hang under specific conditions.This occurs when:- A dm-raid managed device tree is suspended from top to bottom (the top-level RAID device is suspended first, followed by its underlying metadata and data devices)- The top-level RAID device is then removedRemoving the top-level device triggers a hang in the following sequence:the dm-raid destructor calls md_stop(), which tries to flush thewrite-intent bitmap by writing to the metadata sub-devices. However, thesedevices are already suspended, making them unable to complete the write-intentoperations and causing an indefinite block.Fix:- Prevent bitmap flushing when md_stop() is called from dm-raiddestructor context and avoid a quiescing/unquescing cycle which could also cause I/O- Still allow write-intent bitmap flushing when called from dm-raidsuspend contextThis ensures that RAID array teardown can complete successfully even when theunderlying devices are in a suspended state.This second patch uses md_is_rdwr() to distinguish between suspend anddestructor paths as elaborated on above.

CVE-2026-43363 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:x86/apic: Disable x2apic on resume if the kernel expects soWhen resuming from s2ram, firmware may re-enable x2apic mode, which may havebeen disabled by the kernel during boot either because it doesn't support IRQremapping or for other reasons. This causes the kernel to continue using thexapic interface, while the hardware is in x2apic mode, which causes hangs.This happens on defconfig + bare metal + s2ram.Fix this in lapic_resume() by disabling x2apic if the kernel expects it to bedisabled, i.e. when x2apic_mode = 0.The ACPI v6.6 spec, Section 16.3 [1] says firmware restores either thepre-sleep configuration or initial boot configuration for each CPU, includingMSR state: When executing from the power-on reset vector as a result of waking from an S2 or S3 sleep state, the platform firmware performs only the hardware initialization required to restore the system to either the state the platform was in prior to the initial operating system boot, or to the pre-sleep configuration state. In multiprocessor systems, non-boot processors should be placed in the same state as prior to the initial operating system boot. (further ahead) If this is an S2 or S3 wake, then the platform runtime firmware restores minimum context of the system before jumping to the waking vector. This includes: CPU configuration. Platform runtime firmware restores the pre-sleep configuration or initial boot configuration of each CPU (MSR, MTRR, firmware update, SMBase, and so on). Interrupts must be disabled (for IA-32 processors, disabled by CLI instruction). (and other things)So at least as per the spec, re-enablement of x2apic by the firmware isallowed if "x2apic on" is a part of the initial boot configuration.

CVE-2026-43407 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:libceph: Fix potential out-of-bounds access in ceph_handle_auth_reply()This patch fixes an out-of-bounds access in ceph_handle_auth_reply()that can be triggered by a message of type CEPH_MSG_AUTH_REPLY. Inceph_handle_auth_reply(), the value of the payload_len field of such amessage is stored in a variable of type int. A value greater thanINT_MAX leads to an integer overflow and is interpreted as a negativevalue. This leads to decrementing the pointer address by this value andsubsequently accessing it because ceph_decode_need() only checks thatthe memory access does not exceed the end address of the allocation.This patch fixes the issue by changing the data type of payload_len tou32. Additionally, the data type of result_msg_len is changed to u32,as it is also a variable holding a non-negative length.Also, an additional layer of sanity checks is introduced, ensuring thatdirectly after reading it from the message, payload_len andresult_msg_len are not greater than the overall segment length.BUG: KASAN: slab-out-of-bounds in ceph_handle_auth_reply+0x642/0x7a0 [libceph]Read of size 4 at addr ffff88811404df14 by task kworker/20:1/262CPU: 20 UID: 0 PID: 262 Comm: kworker/20:1 Not tainted 6.19.2 #5 PREEMPT(voluntary)Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-debian-1.16.3-2 04/01/2014Workqueue: ceph-msgr ceph_con_workfn [libceph]Call Trace: dump_stack_lvl+0x76/0xa0 print_report+0xd1/0x620 ? __pfx__raw_spin_lock_irqsave+0x10/0x10 ? kasan_complete_mode_report_info+0x72/0x210 kasan_report+0xe7/0x130 ? ceph_handle_auth_reply+0x642/0x7a0 [libceph] ? ceph_handle_auth_reply+0x642/0x7a0 [libceph] __asan_report_load_n_noabort+0xf/0x20 ceph_handle_auth_reply+0x642/0x7a0 [libceph] mon_dispatch+0x973/0x23d0 [libceph] ? apparmor_socket_recvmsg+0x6b/0xa0 ? __pfx_mon_dispatch+0x10/0x10 [libceph] ? __kasan_check_write+0x14/0x30i ? mutex_unlock+0x7f/0xd0 ? __pfx_mutex_unlock+0x10/0x10 ? __pfx_do_recvmsg+0x10/0x10 [libceph] ceph_con_process_message+0x1f1/0x650 [libceph] process_message+0x1e/0x450 [libceph] ceph_con_v2_try_read+0x2e48/0x6c80 [libceph] ? __pfx_ceph_con_v2_try_read+0x10/0x10 [libceph] ? save_fpregs_to_fpstate+0xb0/0x230 ? raw_spin_rq_unlock+0x17/0xa0 ? finish_task_switch.isra.0+0x13b/0x760 ? __switch_to+0x385/0xda0 ? __kasan_check_write+0x14/0x30 ? mutex_lock+0x8d/0xe0 ? __pfx_mutex_lock+0x10/0x10 ceph_con_workfn+0x248/0x10c0 [libceph] process_one_work+0x629/0xf80 ? __kasan_check_write+0x14/0x30 worker_thread+0x87f/0x1570 ? __pfx__raw_spin_lock_irqsave+0x10/0x10 ? __pfx_try_to_wake_up+0x10/0x10 ? kasan_print_address_stack_frame+0x1f7/0x280 ? __pfx_worker_thread+0x10/0x10 kthread+0x396/0x830 ? __pfx__raw_spin_lock_irq+0x10/0x10 ? __pfx_kthread+0x10/0x10 ? __kasan_check_write+0x14/0x30 ? recalc_sigpending+0x180/0x210 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x3f7/0x610 ? __pfx_ret_from_fork+0x10/0x10 ? __switch_to+0x385/0xda0 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1a/0x30 [ idryomov: replace if statements with ceph_decode_need() for payload_len and result_msg_len ]

If aninterrupt fires after usbhs_pipe_remove() but before the driver is fullyunbound, the ISR may access freed memory, causing a use-after-free.Fix this by calling devm_free_irq() before freeing resources. This ensuresthe interrupt handler is both disabled and synchronized (waits for anyrunning ISR to complete) before usbhs_pipe_remove() is called.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nfnetlink_cthelper: fix OOB read in nfnl_cthelper_dump_table()nfnl_cthelper_dump_table() has a 'goto restart' that jumps to a labelinside the for loop body. When the "last" helper saved in cb->args[1]is deleted between dump rounds, every entry fails the (cur != last)check, so cb->args[1] is never cleared. The for loop finishes withcb->args[0] == nf_ct_helper_hsize, and the 'goto restart' jumps backinto the loop body bypassing the bounds check, causing an 8-byteout-of-bounds read on nf_ct_helper_hash[nf_ct_helper_hsize].The 'goto restart' block was meant to re-traverse the current bucketwhen "last" is no longer found, but it was placed after the for loopinstead of inside it. Move the block into the for loop body so thatthe restart only occurs while cb->args[0] is still within bounds.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nfnetlink_queue: fix entry leak in bridge verdict error pathnfqnl_recv_verdict() calls find_dequeue_entry() to remove the queueentry from the queue data structures, taking ownership of the entry.For PF_BRIDGE packets, it then calls nfqa_parse_bridge() to parse VLANattributes. If nfqa_parse_bridge() returns an error (e.g. NFQA_VLANpresent but NFQA_VLAN_TCI missing), the function returns immediatelywithout freeing the dequeued entry or its sk_buff.This leaks the nf_queue_entry, its associated sk_buff, and all heldreferences (net_device refcounts, struct net refcount). Repeatedtriggering exhausts kernel memory.Fix this by dropping the entry via nfqnl_reinject() with NF_DROP verdicton the error path, consistent with other error handling in this file.

Functions like ipgre_header(), ip6gre_header(),all usenetdev_priv(dev) to access their device-specific private data. Whencalled with the bond device, netdev_priv() returns the bond's privatedata (struct bonding) instead of the expected type (e.g. structip_tunnel), leading to garbage values being read and kernel crashes.Fix this by introducing bond_header_ops with wrapper functions thatdelegate to the active slave's header_ops using the slave's owndevice. This ensures netdev_priv() in the slave's header functionsalways receives the correct device.The fix is placed in the bonding driver rather than individual devicedrivers, as the root cause is bond blindly inheriting header_ops fromthe slave without considering that these callbacks expect a specificnetdev_priv() layout.The type confusion can be observed by adding a printk inipgre_header() and running the following commands: ip link add dummy0 type dummy ip addr add 10.0.0.1/24 dev dummy0 ip link set dummy0 up ip link add gre1 type gre local 10.0.0.1 ip link add bond1 type bond mode active-backup ip link set gre1 master bond1 ip link set gre1 up ip link set bond1 up ip addr add fe80::1/64 dev bond1

Description: In the Linux kernel, the following vulnerability has been resolved:unshare: fix unshare_fs() handlingThere's an unpleasant corner case in unshare(2), when we have aCLONE_NEWNS in flags and current->fs hadn't been shared at all; in thatcase copy_mnt_ns() gets passed current->fs instead of a private copy,which causes interesting warts in proof of correctness]> I guess if private means fs->users == 1, the condition could still be true.Unfortunately, it's worse than just a convoluted proof of correctness.Consider the case when we have CLONE_NEWCGROUP in addition to CLONE_NEWNS(and current->fs->users == 1).We pass current->fs to copy_mnt_ns(), all right. Suppose it succeeds andflips current->fs->{pwd,root} to corresponding locations in the new namespace.Now we proceed to copy_cgroup_ns(), which fails (e.g. with -ENOMEM).We call put_mnt_ns() on the namespace created by copy_mnt_ns(), it'sdestroyed and its mount tree is dissolved, but... current->fs->root andcurrent->fs->pwd are both left pointing to now detached mounts.They are pinning those, so it's not a UAF, but it leaves the callingprocess with unshare(2) failing with -ENOMEM _and_ leaving it withpwd and root on detached isolated mounts. The last part is clearly a bug.There is other fun related to that mess (races with pivot_root(), includingthe one between pivot_root() and fork(), of all things), but this oneis easy to isolate and fix - treat CLONE_NEWNS as "allocate a newfs_struct even if it hadn't been shared in the first place". Sure, we couldgo for something like "if both CLONE_NEWNS *and* one of the things that mightend up failing after copy_mnt_ns() call in create_new_namespaces() are set,force allocation of new fs_struct", but let's keep it simple - the costof copy_fs_struct() is trivial.Another benefit is that copy_mnt_ns() with CLONE_NEWNS *always* getsa freshly allocated fs_struct, yet to be attached to anything. Thatseriously simplifies the analysis...FWIW, that bug had been there since the introduction of unshare(2) ;-/

CVE-2026-43483 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: SVM: Set/clear CR8 write interception when AVIC is (de)activatedExplicitly set/clear CR8 write interception when AVIC is (de)activated tofix a bug where KVM leaves the interception enabled after AVIC isactivated. E.g. if KVM emulates INIT=>WFS while AVIC is deactivated, CR8will remain intercepted in perpetuity.On its own, the dangling CR8 intercept is "just" a performance issue, butcombined with the TPR sync bug fixed by commit d02e48830e3f ("KVM: SVM:Sync TPR from LAPIC into VMCB::V_TPR even if AVIC is active"), the dangingintercept is fatal to Windows guests as the TPR seen by hardware getswildly out of sync with reality.Note, VMX isn't affected by the bug as TPR_THRESHOLD is explicitly ignoredwhen Virtual Interrupt Delivery is enabled, i.e. when APICv is active inKVM's world. I.e. there's no need to trigger update_cr8_intercept(), thisis firmly an SVM implementation flaw/detail.WARN if KVM gets a CR8 write #VMEXIT while AVIC is active, as KVM shouldnever enter the guest with AVIC enabled and CR8 writes intercepted.[Squash fix to avic_deactivate_vmcb. - Paolo]

CVE-2026-43492 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:lib/crypto: mpi: Fix integer underflow in mpi_read_raw_from_sgl()Yiming reports an integer underflow in mpi_read_raw_from_sgl() whensubtracting "lzeros" from the unsigned "nbytes".For this to happen, the scatterlist "sgl" needs to occupy more bytesthan the "nbytes" parameter and the first "nbytes + 1" bytes of thescatterlist must be zero. Under these conditions, the while loopiterating over the scatterlist will count more zeroes than "nbytes",subtract the number of zeroes from "nbytes" and cause the underflow.When commit 2d4d1eea540b ("lib/mpi: Add mpi sgl helpers") originallyintroduced the bug, it couldn't be triggered because all callers ofmpi_read_raw_from_sgl() passed a scatterlist whose length was equal to"nbytes".However since commit 63ba4d67594a ("KEYS: asymmetric: Use new cryptointerface without scatterlists"), the underflow can now actually betriggered. When invoking a KEYCTL_PKEY_ENCRYPT system call with alarger "out_len" than "in_len" and filling the "in" buffer with zeroes,crypto_akcipher_sync_prep() will create an all-zero scatterlist used forboth the "src" and "dst" member of struct akcipher_request and therebyfulfil the conditions to trigger the bug: sys_keyctl() keyctl_pkey_e_d_s() asymmetric_key_eds_op() software_key_eds_op() crypto_akcipher_sync_encrypt() crypto_akcipher_sync_prep() crypto_akcipher_encrypt() rsa_enc() mpi_read_raw_from_sgl()To the user this will be visible as a DoS as the kernel spins forever,causing soft lockup splats as a side effect.Fix it.

CVE-2026-43496 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: sch_red: Replace direct dequeue call with peek and qdisc_dequeue_peekedWhen red qdisc has children (eg qfq qdisc) whose peek() callback isqdisc_peek_dequeued(), we could get a kernel panic. When the parent of suchqdiscs (eg illustrated in patch #3 as tbf) wants to retrieve an skb fromits child (red in this case), it will do the following: 1a. do a peek() - and when sensing there's an skb the child can offer, then - the child in this case(red) calls its child's (qfq) peek. qfq does the right thing and will return the gso_skb queue packet. Note: if there wasnt a gso_skb entry then qfq will store it there. 1b. invoke a dequeue() on the child (red). And herein lies the problem. - red will call the child's dequeue() which will essentially just try to grab something of qfq's queue.[ 78.667668][ T363] KASAN: null-ptr-deref in range [0x0000000000000048-0x000000000000004f][ 78.667927][ T363] CPU: 1 UID: 0 PID: 363 Comm: ping Not tainted 7.1.0-rc1-00033-g46f74a3f7d57-dirty #790 PREEMPT(full)[ 78.668263][ T363] Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011[ 78.668486][ T363] RIP: 0010:qfq_dequeue+0x446/0xc90 [sch_qfq][ 78.668718][ T363] Code: 54 c0 e8 dd 90 00 f1 48 c7 c7 e0 03 54 c0 48 89 de e8 ce 90 00 f1 48 8d 7b 48 b8 ff ff 37 00 48 89 fa 48 c1 e0 2a 48 c1 ea 03 <80> 3c 02 00 74 05 e8 ef a1 e1 f1 48 8b 7b 48 48 8d 54 24 58 48 8d[ 78.669312][ T363] RSP: 0018:ffff88810de573e0 EFLAGS: 00010216[ 78.669533][ T363] RAX: dffffc0000000000 RBX: 0000000000000000 RCX: 0000000000000000[ 78.669790][ T363] RDX: 0000000000000009 RSI: 0000000000000004 RDI: 0000000000000048[ 78.670044][ T363] RBP: ffff888110dc4000 R08: ffffffffb1b0885a R09: fffffbfff6ba9078[ 78.670297][ T363] R10: 0000000000000003 R11: ffff888110e31c80 R12: 0000001880000000[ 78.670560][ T363] R13: ffff888110dc4150 R14: ffff888110dc42b8 R15: 0000000000000200[ 78.670814][ T363] FS: 00007f66a8f09c40(0000) GS:ffff888163428000(0000) knlGS:0000000000000000[ 78.671110][ T363] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 78.671324][ T363] CR2: 000055db4c6a30a8 CR3: 000000010da67000 CR4: 0000000000750ef0[ 78.671585][ T363] PKRU: 55555554[ 78.671713][ T363] Call Trace:[ 78.671843][ T363] [ 78.671936][ T363] ? __pfx_qfq_dequeue+0x10/0x10 [sch_qfq][ 78.672148][ T363] ? __pfx__printk+0x10/0x10[ 78.672322][ T363] ? srso_alias_return_thunk+0x5/0xfbef5[ 78.672496][ T363] ? lockdep_hardirqs_on_prepare+0xa8/0x1a0[ 78.672706][ T363] ? srso_alias_return_thunk+0x5/0xfbef5[ 78.672875][ T363] ? trace_hardirqs_on+0x19/0x1a0[ 78.673047][ T363] red_dequeue+0x65/0x270 [sch_red][ 78.673217][ T363] ? srso_alias_return_thunk+0x5/0xfbef5[ 78.673385][ T363] tbf_dequeue.cold+0xb0/0x70c [sch_tbf][ 78.673566][ T363] __qdisc_run+0x169/0x1900The right thing to do in #1b is to grab the skb off gso_skb queue.This patchset fixes that issue by changing #1b to use qdisc_dequeue_peeked()method instead.

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

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

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

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.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nf_conntrack_h323: fix OOB read in decode_int() CONS caseIn decode_int(), the CONS case calls get_bits(bs, 2) to read a lengthvalue, then calls get_uint(bs, len) without checking that len bytesremain in the buffer. The existing boundary check only validates the2 bits for get_bits(), not the subsequent 1-4 bytes that get_uint()reads. This allows a malformed H.323/RAS packet to cause a 1-4 byteslab-out-of-bounds read.Add a boundary check for len bytes after get_bits() and beforeget_uint().

CVE-2026-23457 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nf_conntrack_sip: fix Content-Length u32 truncation in sip_help_tcp()sip_help_tcp() parses the SIP Content-Length header withsimple_strtoul(), which returns unsigned long, but stores the result inunsigned int clen. On 64-bit systems, values exceeding UINT_MAX aresilently truncated before computing the SIP message boundary.For example, Content-Length 4294967328 (2^32 + 32) is truncated to 32,causing the parser to miscalculate where the current message ends. Theloop then treats trailing data in the TCP segment as a second SIPmessage and processes it through the SDP parser.Fix this by changing clen to unsigned long to match the return type ofsimple_strtoul(), and reject Content-Length values that exceed theremaining TCP payload length.

The card'sprivate_free callback, snd_usb_caiaq_card_free(), can runasynchronously via snd_card_free_when_closed() after the USBdevice has already been disconnected and freed, so any access tocdev->chip.dev in that path dereferences a freed usb_device.On top of the refcounting issue, the current card_free implementationcalls usb_reset_device(cdev->chip.dev). A reset in a free callbackis inappropriate: the device is going away, the call takes thedevice lock in a teardown context, and the reset races with thedisconnect path that the callback is already cleaning up after.Take a reference on the USB device in create_card() withusb_get_dev(), drop it with usb_put_dev() in the free callback,and remove the usb_reset_device() call.

Description: In the Linux kernel, the following vulnerability has been resolved:md-cluster: fix NULL pointer dereference in process_metadata_updateThe function process_metadata_update() blindly dereferences the 'thread'pointer (acquired via rcu_dereference_protected) within the wait_event()macro.While the code comment states "daemon thread must exist", there is a validrace condition window during the MD array startup sequence (md_run):1. bitmap_load() is called, which invokes md_cluster_ops->join().2. join() starts the "cluster_recv" thread (recv_daemon).3. At this point, recv_daemon is active and processing messages.4. However, mddev->thread (the main MD thread) is not initialized until later in md_run().If a METADATA_UPDATED message is received from a remote node during thisspecific window, process_metadata_update() will be called whilemddev->thread is still NULL, leading to a kernel panic.To fix this, we must validate the 'thread' pointer. If it is NULL, werelease the held lock (no_new_dev_lockres) and return early, safelyignoring the update request as the array is not yet fully ready toprocess it.

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

CVE-2026-34757 Severity: Moderate CVSS3 score: 5.1

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

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: fix i_data_sem unlock order in ext4_ind_migrate()Fuzzing reports a possible deadlock in jbd2_log_wait_commit.This issue is triggered when an EXT4_IOC_MIGRATE ioctl is set to requiresynchronous updates because the file descriptor is opened with O_SYNC.This can lead to the jbd2_journal_stop() function callingjbd2_might_wait_for_commit(), potentially causing a deadlock if theEXT4_IOC_MIGRATE call races with a write(2) system call.This problem only arises when CONFIG_PROVE_LOCKING is enabled. In thiscase, the jbd2_might_wait_for_commit macro locks jbd2_handle in thejbd2_journal_stop function while i_data_sem is locked. This triggerslockdep because the jbd2_journal_start function might also lock the samejbd2_handle simultaneously.Found by Linux Verification Center (linuxtesting.org) with syzkaller.Rule: add

CVE-2025-4598 Severity: Moderate CVSS3 score: 4.7

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

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---

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-2026-27456 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: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-2024-43790 Severity: Moderate CVSS3 score: 4.5

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

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

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

CVE-2026-31427 Severity: Moderate CVSS3 score: 4.5

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nf_conntrack_sip: fix use of uninitialized rtp_addr in process_sdpprocess_sdp() declares union nf_inet_addr rtp_addr on the stack andpasses it to the nf_nat_sip sdp_session hook after walking the SDPmedia descriptions. However rtp_addr is only initialized inside themedia loop when a recognized media type with a non-zero port is found.If the SDP body contains no m= lines, only inactive media sections(m=audio 0 ...) or only unrecognized media types, rtp_addr is neverassigned. Despite that, the function still calls hooks->sdp_session()with &rtp_addr, causing nf_nat_sdp_session() to format the stale stackvalue as an IP address and rewrite the SDP session owner and connectionlines with it.With CONFIG_INIT_STACK_ALL_ZERO (default on most distributions) thisresults in the session-level o= and c= addresses being rewritten to0.0.0.0 for inactive SDP sessions. Without stack auto-init therewritten address is whatever happened to be on the stack.Fix this by pre-initializing rtp_addr from the session-level connectionaddress (caddr) when available, and tracking via a have_rtp_addr flagwhether any valid address was established. Skip the sdp_session hookentirely when no valid address exists.

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.

CVE-2024-45306 Severity: Moderate CVSS3 score: 4.4

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

This is due to fact that the Thunderbolt networking driveralso tries to cleanup the paths and ends up blocking intb_disconnect_xdomain_paths() waiting for the domain lock.However, at this point we already cleaned the paths in tb_stop() sothere is really no need for tb_disconnect_xdomain_paths() to do thatanymore. Furthermore it already checks if the XDomain is unplugged andbails out early so take advantage of that and mark the XDomain asunplugged when we remove the parent router.

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.

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-2026-31415 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---

This value isstored directly in vhost->num_targets without validation, and is then usedas the loop bound in ibmvfc_alloc_targets() to index into disc_buf[], whichis only allocated for max_targets entries. Indices at or beyond max_targetsaccess kernel memory outside the DMA-coherent allocation. Theout-of-bounds data is subsequently embedded in Implicit Logout and PLOGIMADs that are sent back to the VIO server, leaking kernel memory.Fix by clamping num_written to max_targets before storing it.

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

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: reserve enough transaction items for qgroup ioctlsCurrently our qgroup ioctls don't reserve any space, they just do atransaction join, which does not reserve any space, neither for the quotatree updates nor for the delayed refs generated when updating the quotatree. The quota root uses the global block reserve, which is fine most ofthe time since we don't expect a lot of updates to the quota root, or tobe too close to -ENOSPC such that other critical metadata updates need toresort to the global reserve.However this is not optimal, as not reserving proper space may result in atransaction abort due to not reserving space for delayed refs and thenabusing the use of the global block reserve.For example, the following reproducer (which is unlikely to model anyreal world use case, but just to illustrate the problem), triggers such atransaction abort due to -ENOSPC when running delayed refs: $ cat test.sh #!/bin/bash DEV=/dev/nullb0 MNT=/mnt/nullb0 umount $DEV &> /dev/null # Limit device to 1G so that it's much faster to reproduce the issue. mkfs.btrfs -f -b 1G $DEV mount -o commit=600 $DEV $MNT fallocate -l 800M $MNT/filler btrfs quota enable $MNT for ((i = 1; i <= 400000; i++)); do btrfs qgroup create 1/$i $MNT done umount $MNTWhen running this, we can see in dmesg/syslog that a transaction aborthappened: [436.490] BTRFS error (device nullb0): failed to run delayed ref for logical 30408704 num_bytes 16384 type 176 action 1 ref_mod 1: -28 [436.493] ------------[ cut here ]------------ [436.494] BTRFS: Transaction aborted (error -28) [436.495] WARNING: fs/btrfs/extent-tree.c:2247 at btrfs_run_delayed_refs+0xd9/0x110 [btrfs], CPU#4: umount/2495372 [436.497] Modules linked in: btrfs loop (...)

CVE-2026-44656 Severity: Moderate CVSS3 score: 4.4

Description: Vim is an open source, command line text editor. Prior to version 9.2.0435, an OS command injection vulnerability exists in Vim's :find command-line completion. When the path option contains backtick-enclosed shell commands, those commands are executed during file name completion. Because the path option lacks the P_SECURE flag, it can be set from a modeline, allowing an attacker who controls the contents of a file to execute arbitrary shell commands when the user opens that file in Vim and triggers :find completion. This issue has been patched in version 9.2.0435.

CVE-2024-35221 Severity: Moderate CVSS3 score: 4.3

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

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

CVE-2026-21441 Severity: Moderate CVSS3 score: 4.3

Description: urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP `Content-Encoding` header (e.g., `gzip`, `deflate`, `br`, or `zstd`). When using the streaming API, the library decompresses only the necessary bytes, enabling partial content consumption. Starting in version 1.22 and prior to version 2.6.3, for HTTP redirect responses, the library would read the entire response body to drain the connection and decompress the content unnecessarily. This decompression occurred even before any read methods were called, and configured read limits did not restrict the amount of decompressed data. As a result, there was no safeguard against decompression bombs. A malicious server could exploit this to trigger excessive resource consumption on the client. Applications and libraries are affected when they stream content from untrusted sources by setting `preload_content=False` when they do not disable redirects. Users should upgrade to at least urllib3 v2.6.3, in which the library does not decode content of redirect responses when `preload_content=False`. If upgrading is not immediately possible, disable redirects by setting `redirect=False` for requests to untrusted source.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: f_tcm: Fix NULL pointer dereferences in nexus handlingThe `tpg->tpg_nexus` pointer in the USB Target driver is dynamicallymanaged and tied to userspace configuration via ConfigFS. It can beNULL if the USB host sends requests before the nexus is fullyestablished or immediately after it is dropped.Currently, functions like `bot_submit_command()` and the datatransfer paths retrieve `tv_nexus = tpg->tpg_nexus` and immediatelydereference `tv_nexus->tvn_se_sess` without any validation. If amalicious or misconfigured USB host sends a BOT (Bulk-Only Transport)command during this race window, it triggers a NULL pointerdereference, leading to a kernel panic (local DoS).This exposes an inconsistent API usage within the module, as peerfunctions like `usbg_submit_command()` and `bot_send_bad_response()`correctly implement a NULL check for `tv_nexus` before proceeding.Fix this by bringing consistency to the nexus handling. Add themissing `if (!tv_nexus)` checks to the vulnerable BOT command andrequest processing paths, aborting the command gracefully with anerror instead of crashing the system.

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

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

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.

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.

Before patching, theloop simply checks that the start offset of the dup and dep is within therange. So in a crafted image, if last entry is xfs_dir2_data_unused, wecan change dup->length to dup->length-1 and leave 1 byte of space. In thenext traversal, this space will be considered as dup or dep. We mayencounter an out of bound read when accessing the fixed members.In the patch, we make sure that the remaining bytes large enough to holdan unused entry before accessing xfs_dir2_data_unused andxfs_dir2_data_unused is XFS_DIR2_DATA_ALIGN byte aligned. We also makesure that the remaining bytes large enough to hold a dirent with asingle-byte name before accessing xfs_dir2_data_entry.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:net: af_key: zero aligned sockaddr tail in PF_KEY exportsPF_KEY export paths use `pfkey_sockaddr_size()` when reserving sockaddrpayload space, so IPv6 addresses occupy 32 bytes on the wire. However,`pfkey_sockaddr_fill()` initializes only the first 28 bytes of`struct sockaddr_in6`, leaving the final 4 aligned bytes uninitialized.Not every PF_KEY message is affected.

CVE-2022-49020 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:net/9p: Fix a potential socket leak in p9_socket_openBoth p9_fd_create_tcp() and p9_fd_create_unix() will callp9_socket_open(). If the creation of p9_trans_fd fails,p9_fd_create_tcp() and p9_fd_create_unix() will return anerror directly instead of releasing the cscoket, which willresult in a socket leak.This patch adds sock_release() to fix the leak issue.

Description: In the Linux kernel, the following vulnerability has been resolved:USB: core: Limit the length of unkillable synchronous timeoutsThe usb_control_msg(), usb_bulk_msg(), and usb_interrupt_msg() APIs inusbcore allow unlimited timeout durations. And since they useuninterruptible waits, this leaves open the possibility of hanging atask for an indefinitely long time, with no way to kill it short ofunplugging the target device.To prevent this sort of problem, enforce a maximum limit on the lengthof these unkillable timeouts. The limit chosen here, somewhatarbitrarily, is 60 seconds. On many systems (although not all) thisis short enough to avoid triggering the kernel's hung-task detector.In addition, clear up the ambiguity of negative timeout values bytreating them the same as 0, i.e., using the maximum allowed timeout.

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: qat - fix DMA transfer directionWhen CONFIG_DMA_API_DEBUG is selected, while running the crypto selftest on the QAT crypto algorithms, the function add_dma_entry() reportsa warning similar to the one below, saying that overlapping mappingsare not supported. This occurs in tests where the input and the outputscatter list point to the same buffers (i.e. two different scatter listswhich point to the same chunks of memory).The logic that implements the mapping uses the flag DMA_BIDIRECTIONALfor both the input and the output scatter lists which leads tooverlapped write mappings. These are not supported by the DMA layer.Fix by specifying the correct DMA transfer directions when mappingbuffers. For in-place operations where the input scatter listmatches the output scatter list, buffers are mapped once withDMA_BIDIRECTIONAL, otherwise input buffers are mapped using the flagDMA_TO_DEVICE and output buffers are mapped with DMA_FROM_DEVICE.Overlapping a read mapping with a write mapping is a valid case indma-coherent devices like QAT.The function that frees and unmaps the buffers, qat_alg_free_bufl()has been changed accordingly to the changes to the mapping function.

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

Description: In the Linux kernel, the following vulnerability has been resolved:fsnotify: clear PARENT_WATCHED flags lazilyIn some setups directories can have many (usually negative) dentries.Hence __fsnotify_update_child_dentry_flags() function can take asignificant amount of time. Since the bulk of this function happensunder inode->i_lock this causes a significant contention on the lockwhen we remove the watch from the directory as the__fsnotify_update_child_dentry_flags() call from fsnotify_recalc_mask()races with __fsnotify_update_child_dentry_flags() calls from__fsnotify_parent() happening on children. This can lead upto softlockupreports reported by users.Fix the problem by calling fsnotify_update_children_dentry_flags() toset PARENT_WATCHED flags only when parent starts watching children.When parent stops watching children, clear false positive PARENT_WATCHEDflags lazily in __fsnotify_parent() for each accessed child.

CVE-2024-56644 Severity: Low CVSS3 score: 2.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/ipv6: release expired exception dst cached in socketDst objects get leaked in ip6_negative_advice() when this function isexecuted for an expired IPv6 route located in the exception table. Thereare several conditions that must be fulfilled for the leak to occur:* an ICMPv6 packet indicating a change of the MTU for the path is received, resulting in an exception dst being created* a TCP connection that uses the exception dst for routing packets must start timing out so that TCP begins retransmissions* after the exception dst expires, the FIB6 garbage collector must not run before TCP executes ip6_negative_advice() for the expired exception dstWhen TCP executes ip6_negative_advice() for an exception dst that hasexpired and if no other socket holds a reference to the exception dst, therefcount of the exception dst is 2, which corresponds to the incrementmade by dst_init() and the increment made by the TCP socket for which theconnection is timing out. The refcount made by the socket is neverreleased. The refcount of the dst is decremented in sk_dst_reset() butthat decrement is counteracted by a dst_hold() intentionally placed justbefore the sk_dst_reset() in ip6_negative_advice(). Afterip6_negative_advice() has finished, there is no other object tied to thedst. The socket lost its reference stored in sk_dst_cache and the dst isno longer in the exception table. The exception dst becomes a leakedobject.As a result of this dst leak, an unbalanced refcount is reported for theloopback device of a net namespace being destroyed under kernels that donot contain e5f80fcf869a ("ipv6: give an IPv6 dev to blackhole_netdev"):unregister_netdevice: waiting for lo to become free. Usage count = 2Fix the dst leak by removing the dst_hold() in ip6_negative_advice(). Thepatch that introduced the dst_hold() in ip6_negative_advice() was92f1655aa2b22 ("net: fix __dst_negative_advice() race"). But 92f1655aa2b22merely refactored the code with regards to the dst refcount so the issuewas present even before 92f1655aa2b22. The bug was introduced in54c1a859efd9f ("ipv6: Don't drop cache route entry unless timer actuallyexpired.") where the expired cached route is deleted and the sk_dst_cachemember of the socket is set to NULL by calling dst_negative_advice() butthe refcount belonging to the socket is left unbalanced.The IPv4 version - ipv4_negative_advice() - is not affected by this bug.When the TCP connection times out ipv4_negative_advice() merely resets thesk_dst_cache of the socket while decrementing the refcount of theexception dst.

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

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

CVE-2026-0967 Severity: Low CVSS3 score: 2.2

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

CVE-2022-50583 Severity: Moderate CVSS3 score: 1.9

Description: In the Linux kernel, the following vulnerability has been resolved:md/raid0, raid10: Don't set discard sectors for request queueIt should use disk_stack_limits to get a proper max_discard_sectorsrather than setting a value by stack drivers.And there is a bug. If all member disks are rotational devices,raid0/raid10 set max_discard_sectors. So the member devices arenot ssd/nvme, but raid0/raid10 export the wrong value.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: drop unnecessary user-triggerable WARN_ONCE in verifierl logIt's trivial for user to trigger "verifier log line truncated" warning,as verifier has a fixed-sized buffer of 1024 bytes (as of now), and there are atleast two pieces of user-provided information that can be output throughthis buffer, and both can be arbitrarily sized by user: - BTF names; - BTF.ext source code lines strings.Verifier log buffer should be properly sized for typical verifier stateoutput. But it's sort-of expected that this buffer won't be long enoughin some circumstances. So let's drop the check. In any case code willwork correctly, at worst truncating a part of a single line output.

Connect =======->dwc3_thread_interrupt ->dwc3_ep0_interrupt ->configfs_composite_setup ->composite_setup ->usb_ep_queue ->dwc3_gadget_ep0_queue ->__dwc3_gadget_ep0_queue ->__dwc3_ep0_do_control_data ->dwc3_send_gadget_ep_cmd2. Disconnect ==========->dwc3_thread_interrupt ->dwc3_gadget_disconnect_interrupt ->dwc3_ep0_reset_state ->dwc3_ep0_end_control_data ->dwc3_send_gadget_ep_cmdIn the issue scenario, in Exynos platforms, we observed that controltransfers for the previous connect have not yet been completed and endtransfer command sent as a part of the disconnect sequence andprocessing of USB_ENDPOINT_HALT feature request from the host timeout.This maybe an expected scenario since the controller is processing EPcommands sent as a part of the previous connect. It maybe better toremove WARN_ON in all places where device endpoint commands are sent toavoid unnecessary kernel panic due to warn.

CVE-2025-40104 Severity: Moderate CVSS3 score: 0.0

Description: In the Linux kernel, the following vulnerability has been resolved:ixgbevf: fix mailbox API compatibility by negotiating supported featuresThere was backward compatibility in the terms of mailbox API. Variousdrivers from various OSes supporting 10G adapters from Intel portfoliocould easily negotiate mailbox API.This convention has been broken since introducing API 1.4.Commit 0062e7cc955e ("ixgbevf: add VF IPsec offload code") added supportfor IPSec which is specific only for the kernel ixgbe driver. None of therest of the Intel 10G PF/VF drivers supports it. And actually lack ofsupport was not included in the IPSec implementation - there were no suchcode paths. No possibility to negotiate support for the feature wasintroduced along with introduction of the feature itself.Commit 339f28964147 ("ixgbevf: Add support for new mailbox communicationbetween PF and VF") increasing API version to 1.5 did the same - itintroduced code supported specifically by the PF ESX driver. It altered APIversion for the VF driver in the same time not touching the versiondefined for the PF ixgbe driver. It led to additional discrepancies,as the code provided within API 1.6 cannot be supported for Linux ixgbedriver as it causes crashes.The issue was noticed some time ago and mitigated by Jake within the commitd0725312adf5 ("ixgbevf: stop attempting IPSEC offload on Mailbox API 1.5").As a result we have regression for IPsec support and after increasing APIto version 1.6 ixgbevf driver stopped to support ESX MBX.To fix this mess add new mailbox op asking PF driver about supportedfeatures. Basing on a response determine whether to set support for IPSecand ESX-specific enhanced mailbox.New mailbox op, for compatibility purposes, must be added within new APIrevision, as API version of OOT PF & VF drivers is already increased to1.6 and doesn't incorporate features negotiate op.Features negotiation mechanism gives possibility to be extended with newfeatures when needed in the future.

Description: In the Linux kernel, the following vulnerability has been resolved:soc: fsl: qbman: fix race condition in qman_destroy_fqWhen QMAN_FQ_FLAG_DYNAMIC_FQID is set, there's a race condition betweenfq_table[fq->idx] state and freeing/allocating from the pool andWARN_ON(fq_table[fq->idx]) in qman_create_fq() gets triggered.Indeed, we can have: Thread A Thread B qman_destroy_fq() qman_create_fq() qman_release_fqid() qman_shutdown_fq() gen_pool_free() -- At this point, the fqid is available again -- qman_alloc_fqid() -- so, we can get the just-freed fqid in thread B -- fq->fqid = fqid; fq->idx = fqid * 2; WARN_ON(fq_table[fq->idx]); fq_table[fq->idx] = fq; fq_table[fq->idx] = NULL;And adding some logs between qman_release_fqid() andfq_table[fq->idx] = NULL makes the WARN_ON() trigger a lot more.To prevent that, ensure that fq_table[fq->idx] is set to NULL beforegen_pool_free() is called by using smp_wmb().
