CVE-2025-15467 Severity: Critical CVSS3 score: 9.8

Description: Issue summary: Parsing CMS AuthEnvelopedData message with maliciouslycrafted AEAD parameters can trigger a stack buffer overflow.Impact summary: A stack buffer overflow may lead to a crash, causing Denialof Service, or potentially remote code execution.When parsing CMS AuthEnvelopedData structures that use AEAD ciphers such asAES-GCM, the IV (Initialization Vector) encoded in the ASN.1 parameters iscopied into a fixed-size stack buffer without verifying that its length fitsthe destination. An attacker can supply a crafted CMS message with anoversized IV, causing a stack-based out-of-bounds write before anyauthentication or tag verification occurs.Applications and services that parse untrusted CMS or PKCS#7 content usingAEAD ciphers (e.g., S/MIME AuthEnvelopedData with AES-GCM) are vulnerable.Because the overflow occurs prior to authentication, no valid key materialis required to trigger it. While exploitability to remote code executiondepends on platform and toolchain mitigations, the stack-based writeprimitive represents a severe risk.The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by thisissue, as the CMS implementation is outside the OpenSSL FIPS moduleboundary.OpenSSL 3.6, 3.5, 3.4, 3.3 and 3.0 are vulnerable to this issue.OpenSSL 1.1.1 and 1.0.2 are not affected by this issue.

CVE-2025-11561 Severity: Important CVSS3 score: 8.8

Description: A flaw was found in the integration of Active Directory and the System Security Services Daemon (SSSD) on Linux systems. In default configurations, the Kerberos local authentication plugin (sssd_krb5_localauth_plugin) is enabled, but a fallback to the an2ln plugin is possible. This fallback allows an attacker with permission to modify certain AD attributes (such as userPrincipalName or samAccountName) to impersonate privileged users, potentially resulting in unauthorized access or privilege escalation on domain-joined Linux hosts.

CVE-2025-8067 Severity: Important CVSS3 score: 8.5

Description: A flaw was found in the Udisks daemon, where it allows unprivileged users to create loop devices using the D-BUS system. This is achieved via the loop device handler, which handles requests sent through the D-BUS interface. As two of the parameters of this handle, it receives the file descriptor list and index specifying the file where the loop device should be backed. The function itself validates the index value to ensure it isn't bigger than the maximum value allowed. However, it fails to validate the lower bound, allowing the index parameter to be a negative value. Under these circumstances, an attacker can cause the UDisks daemon to crash or perform a local privilege escalation by gaining access to files owned by privileged users.

CVE-2025-38499 Severity: Important CVSS3 score: 8.4

Description: In the Linux kernel, the following vulnerability has been resolved:clone_private_mnt(): make sure that caller has CAP_SYS_ADMIN in the right usernsWhat we want is to verify there is that clone won't expose somethinghidden by a mount we wouldn't be able to undo. "Wouldn't be able to undo"may be a result of MNT_LOCKED on a child, but it may also come fromlacking admin rights in the userns of the namespace mount belongs to.clone_private_mnt() checks the former, but not the latter.There's a number of rather confusing CAP_SYS_ADMIN checks in varioususerns during the mount, especially with the new mount API; they servedifferent purposes and in case of clone_private_mnt() they usually,but not always end up covering the missing check mentioned above.

Description: In the Linux kernel, the following vulnerability has been resolved:sunrpc: fix handling of server side tls alertsScott Mayhew discovered a security exploit in NFS over TLS intls_alert_recv() due to its assumption it can read data fromthe msg iterator's kvec..kTLS implementation splits TLS non-data record payload betweenthe control message buffer (which includes the type such as TLSaler or TLS cipher change) and the rest of the payload (say TLSalert's level/description) which goes into the msg payload buffer.This patch proposes to rework how control messages are setup andused by sock_recvmsg().If no control message structure is setup, kTLS layer will read andprocess TLS data record types. As soon as it encounters a TLS controlmessage, it would return an error. At that point, NFS can setup akvec backed msg buffer and read in the control message such as aTLS alert. Msg iterator can advance the kvec pointer as a part ofthe copy process thus we need to revert the iterator before callinginto the tls_alert_recv.

CVE-2025-31133 Severity: Important CVSS3 score: 7.8

Description: runc is a CLI tool for spawning and running containers according to the OCI specification. In versions 1.2.7 and below, 1.3.0-rc.1 through 1.3.1, 1.4.0-rc.1 and 1.4.0-rc.2 files, runc would not perform sufficient verification that the source of the bind-mount (i.e., the container's /dev/null) was actually a real /dev/null inode when using the container's /dev/null to mask. This exposes two methods of attack: an arbitrary mount gadget, leading to host information disclosure, host denial of service, container escape, or a bypassing of maskedPaths. This issue is fixed in versions 1.2.8, 1.3.3 and 1.4.0-rc.3.

Description: In the Linux kernel, the following vulnerability has been resolved:dm: fix dm_blk_report_zonesIf dm_get_live_table() returned NULL, dm_put_live_table() was nevercalled. Also, it is possible that md->zone_revalidate_map will changewhile calling this function. Only read it once, so that we are alwaysusing the same value. Otherwise we might miss a call todm_put_live_table().Finally, while md->zone_revalidate_map is set and a process is callingblk_revalidate_disk_zones() to set up the zone append emulationresources, it is possible that another process, perhaps triggered byblkdev_report_zones_ioctl(), will call dm_blk_report_zones(). Ifblk_revalidate_disk_zones() fails, these resources can be freed whilethe other process is still using them, causing a use-after-free error.blk_revalidate_disk_zones() will only ever be called when initiallysetting up the zone append emulation resources, such as when setting upa zoned dm-crypt table for the first time. Further table swaps will notset md->zone_revalidate_map or call blk_revalidate_disk_zones().However it must be called using the new table (referenced bymd->zone_revalidate_map) and the new queue limits while the DM device issuspended. dm_blk_report_zones() needs some way to distinguish between acall from blk_revalidate_disk_zones(), which must be allowed to usemd->zone_revalidate_map to access this not yet activated table, and allother calls to dm_blk_report_zones(), which should not be allowed whilethe device is suspended and cannot use md->zone_revalidate_map, sincethe zone resources might be freed by the process currently callingblk_revalidate_disk_zones().Solve this by tracking the process that sets md->zone_revalidate_map indm_revalidate_zones() and only allowing that process to make use of itin dm_blk_report_zones().

Description: In the Linux kernel, the following vulnerability has been resolved:s390/pkey: Prevent overflow in size calculation for memdup_user()Number of apqn target list entries contained in 'nr_apqns' variable isdetermined by userspace via an ioctl call so the result of the product incalculation of size passed to memdup_user() may overflow.In this case the actual size of the allocated area and the valuedescribing it won't be in sync leading to various types of unpredictablebehaviour later.Use a proper memdup_array_user() helper which returns an error if anoverflow is detected. Note that it is different from when nr_apqns isinitially zero - that case is considered valid and should be handled insubsequent pkey_handler implementations.Found by Linux Verification Center (linuxtesting.org).

CVE-2025-38377 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:rose: fix dangling neighbour pointers in rose_rt_device_down()There are two bugs in rose_rt_device_down() that can causeuse-after-free:1. The loop bound `t->count` is modified within the loop, which can cause the loop to terminate early and miss some entries.2. When removing an entry from the neighbour array, the subsequent entries are moved up to fill the gap, but the loop index `i` is still incremented, causing the next entry to be skipped.For example, if a node has three neighbours (A, A, B) with count=3 and Ais being removed, the second A is not checked. i=0: (A, A, B) -> (A, B) with count=2 ^ checked i=1: (A, B) -> (A, B) with count=2 ^ checked (B, not A!) i=2: (doesn't occur because i < count is false)This leaves the second A in the array with count=2, but the rose_neighstructure has been freed. Code that accesses these entries assumes thatthe first `count` entries are valid pointers, causing a use-after-freewhen it accesses the dangling pointer.Fix both issues by iterating over the array in reverse order with a fixedloop bound. This ensures that all entries are examined and that the removalof an entry doesn't affect subsequent iterations.

CVE-2025-38396 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:fs: export anon_inode_make_secure_inode() and fix secretmem LSM bypassExport anon_inode_make_secure_inode() to allow KVM guest_memfd to createanonymous inodes with proper security context. This replaces the currentpattern of calling alloc_anon_inode() followed byinode_init_security_anon() for creating security context manually.This change also fixes a security regression in secretmem where theS_PRIVATE flag was not cleared after alloc_anon_inode(), causingLSM/SELinux checks to be bypassed for secretmem file descriptors.As guest_memfd currently resides in the KVM module, we need to export thissymbol for use outside the core kernel. In the future, guest_memfd might bemoved to core-mm, at which point the symbols no longer would have to beexported. When/if that happens is still unclear.

CVE-2025-38488 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: fix use-after-free in crypt_message when using async cryptoThe CVE-2024-50047 fix removed asynchronous crypto handling fromcrypt_message(), assuming all crypto operations are synchronous.However, when hardware crypto accelerators are used, this can causeuse-after-free crashes: crypt_message() // Allocate the creq buffer containing the req creq = smb2_get_aead_req(..., &req); // Async encryption returns -EINPROGRESS immediately rc = enc ? crypto_aead_encrypt(req) : crypto_aead_decrypt(req); // Free creq while async operation is still in progress kvfree_sensitive(creq, ...);Hardware crypto modules often implement async AEAD operations forperformance. When crypto_aead_encrypt/decrypt() returns -EINPROGRESS,the operation completes asynchronously. Without crypto_wait_req(),the function immediately frees the request buffer, leading to crasheswhen the driver later accesses the freed memory.This results in a use-after-free condition when the hardware cryptodriver later accesses the freed request structure, leading to kernelcrashes with NULL pointer dereferences.The issue occurs because crypto_alloc_aead() with mask=0 doesn'tguarantee synchronous operation. Even without CRYPTO_ALG_ASYNC inthe mask, async implementations can be selected.Fix by restoring the async crypto handling:- DECLARE_CRYPTO_WAIT(wait) for completion tracking- aead_request_set_callback() for async completion notification- crypto_wait_req() to wait for operation completionThis ensures the request buffer isn't freed until the crypto operationcompletes, whether synchronous or asynchronous, while preserving theCVE-2024-50047 fix.

CVE-2025-38585 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:staging: media: atomisp: Fix stack buffer overflow in gmin_get_var_int()When gmin_get_config_var() calls efi.get_variable() and the EFI variableis larger than the expected buffer size, two behaviors combine to createa stack buffer overflow:1. gmin_get_config_var() does not return the proper error code when efi.get_variable() fails. It returns the stale 'ret' value from earlier operations instead of indicating the EFI failure.2. When efi.get_variable() returns EFI_BUFFER_TOO_SMALL, it updates *out_len to the required buffer size but writes no data to the output buffer. However, due to bug #1, gmin_get_var_int() believes the call succeeded.The caller gmin_get_var_int() then performs:- Allocates val[CFG_VAR_NAME_MAX + 1] (65 bytes) on stack- Calls gmin_get_config_var(dev, is_gmin, var, val, &len) with len=64- If EFI variable is >64 bytes, efi.get_variable() sets len=required_size- Due to bug #1, thinks call succeeded with len=required_size- Executes val[len] = 0, writing past end of 65-byte stack bufferThis creates a stack buffer overflow when EFI variables are larger than64 bytes. Since EFI variables can be controlled by firmware or systemconfiguration, this could potentially be exploited for code execution.Fix the bug by returning proper error codes from gmin_get_config_var()based on EFI status instead of stale 'ret' value.The gmin_get_var_int() function is called during device initializationfor camera sensor configuration on Intel Bay Trail and Cherry Trailplatforms using the atomisp camera stack.

CVE-2025-39790 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:bus: mhi: host: Detect events pointing to unexpected TREsWhen a remote device sends a completion event to the host, it contains apointer to the consumed TRE. The host uses this pointer to process all ofthe TREs between it and the host's local copy of the ring's read pointer.This works when processing completion for chained transactions, but canlead to nasty results if the device sends an event for a single-elementtransaction with a read pointer that is multiple elements ahead of thehost's read pointer.For instance, if the host accesses an event ring while the device isupdating it, the pointer inside of the event might still point to an oldTRE. If the host uses the channel's xfer_cb() to directly free the bufferpointed to by the TRE, the buffer will be double-freed.This behavior was observed on an ep that used upstream EP stack without'commit 6f18d174b73d ("bus: mhi: ep: Update read pointer only after bufferis written")'. Where the device updated the events ring pointer beforeupdating the event contents, so it left a window where the host was able toaccess the stale data the event pointed to, before the device had thechance to update them. The usual pattern was that the host received anevent pointing to a TRE that is not immediately after the last processedone, so it got treated as if it was a chained transaction, processing allof the TREs in between the two read pointers.This commit aims to harden the host by ensuring transactions where theevent points to a TRE that isn't local_rp + 1 are chained.[mani: added stable tag and reworded commit message]

CVE-2025-39827 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:net: rose: include node references in rose_neigh refcountCurrent implementation maintains two separate reference countingmechanisms: the 'count' field in struct rose_neigh tracks references fromrose_node structures, while the 'use' field (now refcount_t) tracksreferences from rose_sock.This patch merges these two reference counting systems using 'use' fieldfor proper reference management. Specifically, this patch adds incrementingand decrementing of rose_neigh->use when rose_neigh->count is incrementedor decremented.This patch also modifies rose_rt_free(), rose_rt_device_down() androse_clear_route() to properly release references to rose_neigh objectsbefore freeing a rose_node through rose_remove_node().These changes ensure rose_neigh structures are properly freed only whenall references, including those from rose_node structures, are released.As a result, this resolves a slab-use-after-free issue reported by Syzbot.

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

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

CVE-2025-52565 Severity: Important CVSS3 score: 7.8

Description: runc is a CLI tool for spawning and running containers according to the OCI specification. Versions 1.0.0-rc3 through 1.2.7, 1.3.0-rc.1 through 1.3.2, and 1.4.0-rc.1 through 1.4.0-rc.2, due to insufficient checks when bind-mounting `/dev/pts/$n` to `/dev/console` inside the container, an attacker can trick runc into bind-mounting paths which would normally be made read-only or be masked onto a path that the attacker can write to. This attack is very similar in concept and application to CVE-2025-31133, except that it attacks a similar vulnerability in a different target (namely, the bind-mount of `/dev/pts/$n` to `/dev/console` as configured for all containers that allocate a console). This happens after `pivot_root(2)`, so this cannot be used to write to host files directly -- however, as with CVE-2025-31133, this can load to denial of service of the host or a container breakout by providing the attacker with a writable copy of `/proc/sysrq-trigger` or `/proc/sys/kernel/core_pattern` (respectively). This issue is fixed in versions 1.2.8, 1.3.3 and 1.4.0-rc.3.

CVE-2025-52881 Severity: Important CVSS3 score: 7.8

Description: runc is a CLI tool for spawning and running containers according to the OCI specification. In versions 1.2.7, 1.3.2 and 1.4.0-rc.2, an attacker can trick runc into misdirecting writes to /proc to other procfs files through the use of a racing container with shared mounts (we have also verified this attack is possible to exploit using a standard Dockerfile with docker buildx build as that also permits triggering parallel execution of containers with custom shared mounts configured). This redirect could be through symbolic links in a tmpfs or theoretically other methods such as regular bind-mounts. While similar, the mitigation applied for the related CVE, CVE-2019-19921, was fairly limited and effectively only caused runc to verify that when LSM labels are written they are actually procfs files. This issue is fixed in versions 1.2.8, 1.3.3, and 1.4.0-rc.3.

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

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

CVE-2024-4067 Severity: Important CVSS3 score: 7.5

Description: The NPM package `micromatch` prior to 4.0.8 is vulnerable to Regular Expression Denial of Service (ReDoS). The vulnerability occurs in `micromatch.braces()` in `index.js` because the pattern `.*` will greedily match anything. By passing a malicious payload, the pattern matching will keep backtracking to the input while it doesn't find the closing bracket. As the input size increases, the consumption time will also increase until it causes the application to hang or slow down. There was a merged fix but further testing shows the issue persists. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching. This issue was fixed in version 4.0.8.

CVE-2025-11187 Severity: Important CVSS3 score: 7.5

Description: Issue summary: PBMAC1 parameters in PKCS#12 files are missing validationwhich can trigger a stack-based buffer overflow, invalid pointer or NULLpointer dereference during MAC verification.Impact summary: The stack buffer overflow or NULL pointer dereference maycause a crash leading to Denial of Service for an application that parsesuntrusted PKCS#12 files. The buffer overflow may also potentially enablecode execution depending on platform mitigations.When verifying a PKCS#12 file that uses PBMAC1 for the MAC, the PBKDF2salt and keylength parameters from the file are used without validation.If the value of keylength exceeds the size of the fixed stack buffer usedfor the derived key (64 bytes), the key derivation will overflow the buffer.The overflow length is attacker-controlled. Also, if the salt parameter isnot an OCTET STRING type this can lead to invalid or NULL pointerdereference.Exploiting this issue requires a user or application to processa maliciously crafted PKCS#12 file. It is uncommon to accept untrustedPKCS#12 files in applications as they are usually used to store privatekeys which are trusted by definition. For this reason the issue was assessedas Moderate severity.The FIPS modules in 3.6, 3.5 and 3.4 are not affected by this issue, asPKCS#12 processing is outside the OpenSSL FIPS module boundary.OpenSSL 3.6, 3.5 and 3.4 are vulnerable to this issue.OpenSSL 3.3, 3.0, 1.1.1 and 1.0.2 are not affected by this issue as they donot support PBMAC1 in PKCS#12.

Description: Issue summary: If an application using the SSL_CIPHER_find() function ina QUIC protocol client or server receives an unknown cipher suite fromthe peer, a NULL dereference occurs.Impact summary: A NULL pointer dereference leads to abnormal termination ofthe running process causing Denial of Service.Some applications call SSL_CIPHER_find() from the client_hello_cb callbackon the cipher ID received from the peer. If this is done with an SSL objectimplementing the QUIC protocol, NULL pointer dereference will happen ifthe examined cipher ID is unknown or unsupported.As it is not very common to call this function in applications using the QUIC protocol and the worst outcome is Denial of Service, the issue was assessedas Low severity.The vulnerable code was introduced in the 3.2 version with the additionof the QUIC protocol support.The FIPS modules in 3.6, 3.5, 3.4 and 3.3 are not affected by this issue,as the QUIC implementation is outside the OpenSSL FIPS module boundary.OpenSSL 3.6, 3.5, 3.4 and 3.3 are vulnerable to this issue.OpenSSL 3.0, 1.1.1 and 1.0.2 are not affected by this issue.

CVE-2025-38089 Severity: Important CVSS3 score: 7.5

Description: In the Linux kernel, the following vulnerability has been resolved:sunrpc: handle SVC_GARBAGE during svc auth processing as auth errortianshuo han reported a remotely-triggerable crash if the client sends akernel RPC server a specially crafted packet. If decoding the RPC replyfails in such a way that SVC_GARBAGE is returned without setting therq_accept_statp pointer, then that pointer can be dereferenced and avalue stored there.If it's the first time the thread has processed an RPC, then thatpointer will be set to NULL and the kernel will crash. In other cases,it could create a memory scribble.The server sunrpc code treats a SVC_GARBAGE return from svc_authenticateor pg_authenticate as if it should send a GARBAGE_ARGS reply. RFC 5531says that if authentication fails that the RPC should be rejectedinstead with a status of AUTH_ERR.Handle a SVC_GARBAGE return as an AUTH_ERROR, with a reason ofAUTH_BADCRED instead of returning GARBAGE_ARGS in that case. Thissidesteps the whole problem of touching the rpc_accept_statp pointer inthis situation and avoids the crash.

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

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

Description: Rack is a modular Ruby web server interface. Prior to versions 2.2.20, 3.1.18, and 3.2.3, `Rack::Request#POST` reads the entire request body into memory for `Content-Type: application/x-www-form-urlencoded`, calling `rack.input.read(nil)` without enforcing a length or cap. Large request bodies can therefore be buffered completely into process memory before parsing, leading to denial of service (DoS) through memory exhaustion. Users should upgrade to Rack version 2.2.20, 3.1.18, or 3.2.3, anu of which enforces form parameter limits using `query_parser.bytesize_limit`, preventing unbounded reads of `application/x-www-form-urlencoded` bodies. Additionally, enforce strict maximum body size at the proxy or web server layer (e.g., Nginx `client_max_body_size`, Apache `LimitRequestBody`).

CVE-2025-68775 Severity: Important CVSS3 score: 7.5

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:ipvs: fix ipv4 null-ptr-deref in route error pathThe IPv4 code path in __ip_vs_get_out_rt() calls dst_link_failure()without ensuring skb->dev is set, leading to a NULL pointer dereferencein fib_compute_spec_dst() when ipv4_link_failure() attempts to sendICMP destination unreachable messages.The issue emerged after commit ed0de45a1008 ("ipv4: recompile ip optionsin ipv4_link_failure") started calling __ip_options_compile() fromipv4_link_failure(). This code path eventually calls fib_compute_spec_dst()which dereferences skb->dev. An attempt was made to fix the NULL skb->devdereference in commit 0113d9c9d1cc ("ipv4: fix null-deref inipv4_link_failure"), but it only addressed the immediate dev_net(skb->dev)dereference by using a fallback device. The fix was incomplete becausefib_compute_spec_dst() later in the call chain still accesses skb->devdirectly, which remains NULL when IPVS calls dst_link_failure().The crash occurs when:1. IPVS processes a packet in NAT mode with a misconfigured destination2. Route lookup fails in __ip_vs_get_out_rt() before establishing a route3. The error path calls dst_link_failure(skb) with skb->dev == NULL4. ipv4_link_failure() -> ipv4_send_dest_unreach() -> __ip_options_compile() -> fib_compute_spec_dst()5. fib_compute_spec_dst() dereferences NULL skb->devApply the same fix used for IPv6 in commit 326bf17ea5d4 ("ipvs: fixipv6 route unreach panic"): set skb->dev from skb_dst(skb)->dev beforecalling dst_link_failure().KASAN: null-ptr-deref in range [0x0000000000000328-0x000000000000032f]CPU: 1 PID: 12732 Comm: syz.1.3469 Not tainted 6.6.114 #2RIP: 0010:__in_dev_get_rcu include/linux/inetdevice.h:233RIP: 0010:fib_compute_spec_dst+0x17a/0x9f0 net/ipv4/fib_frontend.c:285Call Trace: spec_dst_fill net/ipv4/ip_options.c:232 spec_dst_fill net/ipv4/ip_options.c:229 __ip_options_compile+0x13a1/0x17d0 net/ipv4/ip_options.c:330 ipv4_send_dest_unreach net/ipv4/route.c:1252 ipv4_link_failure+0x702/0xb80 net/ipv4/route.c:1265 dst_link_failure include/net/dst.h:437 __ip_vs_get_out_rt+0x15fd/0x19e0 net/netfilter/ipvs/ip_vs_xmit.c:412 ip_vs_nat_xmit+0x1d8/0xc80 net/netfilter/ipvs/ip_vs_xmit.c:764

Description: AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. In versions 3.13.2 and below, handling of chunked messages can result in excessive blocking CPU usage when receiving a large number of chunks. If an application makes use of the request.read() method in an endpoint, it may be possible for an attacker to cause the server to spend a moderate amount of blocking CPU time (e.g. 1 second) while processing the request. This could potentially lead to DoS as the server would be unable to handle other requests during that time. This issue is fixed in version 3.13.3.

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

Description: In the Linux kernel, the following vulnerability has been resolved:tls: handle data disappearing from under the TLS ULPTLS expects that it owns the receive queue of the TCP socket.This cannot be guaranteed in case the reader of the TCP socketentered before the TLS ULP was installed, or uses some non-standardread API (eg. zerocopy ones). Replace the WARN_ON() and a buggyearly exit (which leaves anchor pointing to a freed skb) with realerror handling. Wipe the parsing state and tell the reader to retry.We already reload the anchor every time we (re)acquire the socket lock,so the only condition we need to avoid is an out of bounds read(not having enough bytes in the socket for previously parsed record len).If some data was read from under TLS but there's enough in the queuewe'll reload and decrypt what is most likely not a valid TLS record.Leading to some undefined behavior from TLS perspective (corruptinga stream? missing an alert? missing an attack?) but no kernel crashshould take place.

CVE-2025-38350 Severity: Important CVSS3 score: 7.3

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: Always pass notifications when child class becomes emptyCertain classful qdiscs may invoke their classes' dequeue handler on anenqueue operation. This may unexpectedly empty the child qdisc and thusmake an in-flight class passive via qlen_notify(). Most qdiscs do notexpect such behaviour at this point in time and may re-activate theclass eventually anyways which will lead to a use-after-free.The referenced fix commit attempted to fix this behavior for the HFSCcase by moving the backlog accounting around, though this turned out tobe incomplete since the parent's parent may run into the issue too.The following reproducer demonstrates this use-after-free: tc qdisc add dev lo root handle 1: drr tc filter add dev lo parent 1: basic classid 1:1 tc class add dev lo parent 1: classid 1:1 drr tc qdisc add dev lo parent 1:1 handle 2: hfsc def 1 tc class add dev lo parent 2: classid 2:1 hfsc rt m1 8 d 1 m2 0 tc qdisc add dev lo parent 2:1 handle 3: netem tc qdisc add dev lo parent 3:1 handle 4: blackhole echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888 tc class delete dev lo classid 1:1 echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888Since backlog accounting issues leading to a use-after-frees on staleclass pointers is a recurring pattern at this point, this patch takesa different approach. Instead of trying to fix the accounting, the patchensures that qdisc_tree_reduce_backlog always calls qlen_notify whenthe child qdisc is empty. This solves the problem because deletion ofqdiscs always involves a call to qdisc_reset() and / orqdisc_purge_queue() which ultimately resets its qlen to 0 thus causingthe following qdisc_tree_reduce_backlog() to report to the parent. Notethat this may call qlen_notify on passive classes multiple times. Thisis not a problem after the recent patch series that made all theclassful qdiscs qlen_notify() handlers idempotent.

[2][3]At that time, an ugly hack was suggested [4], but it makes both INETand SMC code error-prone and hard to change.Also, yet another variant was fixed by a hacky commit 98d4435efcbf3("net/smc: prevent NULL pointer dereference in txopt_get").Instead of papering over the root cause by such hacks, we should notallow non-INET socket to reuse the INET infra.Let's add inet_sock as the first member of smc_sock.[0]:kvfree_call_rcu(): Double-freed call. rcu_head 000000006921da73WARNING: CPU: 0 PID: 6718 at mm/slab_common.c:1956 kvfree_call_rcu+0x94/0x3f0 mm/slab_common.c:1955Modules linked in:CPU: 0 UID: 0 PID: 6718 Comm: syz.0.17 Tainted: G W 6.16.0-rc4-syzkaller-g7482bb149b9f #0 PREEMPTTainted: [W]=WARNHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 05/07/2025pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--)pc : kvfree_call_rcu+0x94/0x3f0 mm/slab_common.c:1955lr : kvfree_call_rcu+0x94/0x3f0 mm/slab_common.c:1955sp : ffff8000a03a7730x29: ffff8000a03a7730 x28: 00000000fffffff5 x27: 1fffe000184823d3x26: dfff800000000000 x25: ffff0000c2411e9e x24: ffff0000dd88da00x23: ffff8000891ac9a0 x22: 00000000ffffffea x21: ffff8000891ac9a0x20: ffff8000891ac9a0 x19: ffff80008afc2480 x18: 00000000ffffffffx17: 0000000000000000 x16: ffff80008ae642c8 x15: ffff700011ede14cx14: 1ffff00011ede14c x13: 0000000000000004 x12: ffffffffffffffffx11: ffff700011ede14c x10: 0000000000ff0100 x9 : 5fa3c1ffaf0ff000x8 : 5fa3c1ffaf0ff000 x7 : 0000000000000001 x6 : 0000000000000001x5 : ffff8000a03a7078 x4 : ffff80008f766c20 x3 : ffff80008054d360x2 : 0000000000000000 x1 : 0000000000000201 x0 : 0000000000000000Call trace: kvfree_call_rcu+0x94/0x3f0 mm/slab_common.c:1955 (P) cipso_v4_sock_setattr+0x2f0/0x3f4 net/ipv4/cipso_ipv4.c:1914 netlbl_sock_setattr+0x240/0x334 net/netlabel/netlabel_kapi.c:1000 smack_netlbl_add+0xa8/0x158 security/smack/smack_lsm.c:2581 smack_inode_setsecurity+0x378/0x430 security/smack/smack_lsm.c:2912 security_inode_setsecurity+0x118/0x3c0 security/security.c:2706 __vfs_setxattr_noperm+0x174/0x5c4 fs/xattr.c:251 __vfs_setxattr_locked+0x1ec/0x218 fs/xattr.c:295 vfs_setxattr+0x158/0x2ac fs/xattr.c:321 do_setxattr fs/xattr.c:636 [inline] file_setxattr+0x1b8/0x294 fs/xattr.c:646 path_setxattrat+0x2ac/0x320 fs/xattr.c:711 __do_sys_fsetxattr fs/xattr.c:761 [inline] __se_sys_fsetxattr fs/xattr.c:758 [inline] __arm64_sys_fsetxattr+0xc0/0xdc fs/xattr.c:758 __invoke_syscall arch/arm64/kernel/syscall.c:35 [inline] invoke_syscall+0x98/0x2b8 arch/arm64/kernel/syscall.c:49 el0_svc_common+0x130/0x23c arch/arm64/kernel/syscall.c:132 do_el0_svc+0x48/0x58 arch/arm64/kernel/syscall.c:151 el0_svc+0x58/0x180 arch/arm64/kernel/entry-common.c:879 el0t_64_sync_handler+0x84/0x12c arch/arm64/kernel/entry-common.c:898 el0t_64_sync+0x198/0x19c arch/arm64/kernel/entry.S:600[---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:bpf, ktls: Fix data corruption when using bpf_msg_pop_data() in ktlsWhen sending plaintext data, we initially calculated the correspondingciphertext length. However, if we later reduced the plaintext data lengthvia socket policy, we failed to recalculate the ciphertext length.This results in transmitting buffers containing uninitialized data duringciphertext transmission.This causes uninitialized bytes to be appended after a complete"Application Data" packet, leading to errors on the receiving end whenparsing TLS record.

Description: In the Linux kernel, the following vulnerability has been resolved:gfs2: No more self recoveryWhen a node withdraws and it turns out that it is the only node that hasthe filesystem mounted, gfs2 currently tries to replay the local journalto bring the filesystem back into a consistent state. Not only is thata very bad idea, it has also never worked because gfs2_recover_func()will refuse to do anything during a withdraw.However, before even getting to this point, gfs2_recover_func()dereferences sdp->sd_jdesc->jd_inode. This was a use-after-free beforecommit 04133b607a78 ("gfs2: Prevent double iput for journal on error")and is a NULL pointer dereference since then.Simply get rid of self recovery to fix that.

CVE-2025-38352 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()If an exiting non-autoreaping task has already passed exit_notify() andcalls handle_posix_cpu_timers() from IRQ, it can be reaped by its parentor debugger right after unlock_task_sighand().If a concurrent posix_cpu_timer_del() runs at that moment, it won't beable to detect timer->it.cpu.firing != 0: cpu_timer_task_rcu() and/orlock_task_sighand() will fail.Add the tsk->exit_state check into run_posix_cpu_timers() to fix this.This fix is not needed if CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y, becauseexit_task_work() is called before exit_notify(). But the check stillmakes sense, task_work_add(&tsk->posix_cputimers_work.work) will failanyway in this case.

Description: In the Linux kernel, the following vulnerability has been resolved:xfrm: interface: fix use-after-free after changing collect_md xfrm interfacecollect_md property on xfrm interfaces can only be set on device creation,thus xfrmi_changelink() should fail when called on such interfaces.The check to enforce this was done only in the case where the xi wasreturned from xfrmi_locate() which doesn't look for the collect_mdinterface, and thus the validation was never reached.Calling changelink would thus errornously place the special interface xiin the xfrmi_net->xfrmi hash, but since it also exists in thexfrmi_net->collect_md_xfrmi pointer it would lead to a double free whenthe net namespace was taken down [1].Change the check to use the xi from netdev_priv which is available earlierin the function to prevent changes in xfrm collect_md interfaces.[1] resulting oops:[ 8.516540] kernel BUG at net/core/dev.c:12029![ 8.516552] Oops: invalid opcode: 0000 [#1] SMP NOPTI[ 8.516559] CPU: 0 UID: 0 PID: 12 Comm: kworker/u80:0 Not tainted 6.15.0-virtme #5 PREEMPT(voluntary)[ 8.516565] Hardware name: QEMU Ubuntu 24.04 PC (i440FX + PIIX, 1996), BIOS 1.16.3-debian-1.16.3-2 04/01/2014[ 8.516569] Workqueue: netns cleanup_net[ 8.516579] RIP: 0010:unregister_netdevice_many_notify+0x101/0xab0[ 8.516590] Code: 90 0f 0b 90 48 8b b0 78 01 00 00 48 8b 90 80 01 00 00 48 89 56 08 48 89 32 4c 89 80 78 01 00 00 48 89 b8 80 01 00 00 eb ac 90 <0f> 0b 48 8b 45 00 4c 8d a0 88 fe ff ff 48 39 c5 74 5c 41 80 bc 24[ 8.516593] RSP: 0018:ffffa93b8006bd30 EFLAGS: 00010206[ 8.516598] RAX: ffff98fe4226e000 RBX: ffffa93b8006bd58 RCX: ffffa93b8006bc60[ 8.516601] RDX: 0000000000000004 RSI: 0000000000000000 RDI: dead000000000122[ 8.516603] RBP: ffffa93b8006bdd8 R08: dead000000000100 R09: ffff98fe4133c100[ 8.516605] R10: 0000000000000000 R11: 00000000000003d2 R12: ffffa93b8006be00[ 8.516608] R13: ffffffff96c1a510 R14: ffffffff96c1a510 R15: ffffa93b8006be00[ 8.516615] FS: 0000000000000000(0000) GS:ffff98fee73b7000(0000) knlGS:0000000000000000[ 8.516619] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 8.516622] CR2: 00007fcd2abd0700 CR3: 000000003aa40000 CR4: 0000000000752ef0[ 8.516625] PKRU: 55555554[ 8.516627] Call Trace:[ 8.516632] [ 8.516635] ? rtnl_is_locked+0x15/0x20[ 8.516641] ? unregister_netdevice_queue+0x29/0xf0[ 8.516650] ops_undo_list+0x1f2/0x220[ 8.516659] cleanup_net+0x1ad/0x2e0[ 8.516664] process_one_work+0x160/0x380[ 8.516673] worker_thread+0x2aa/0x3c0[ 8.516679] ? __pfx_worker_thread+0x10/0x10[ 8.516686] kthread+0xfb/0x200[ 8.516690] ? __pfx_kthread+0x10/0x10[ 8.516693] ? __pfx_kthread+0x10/0x10[ 8.516697] ret_from_fork+0x82/0xf0[ 8.516705] ? __pfx_kthread+0x10/0x10[ 8.516709] ret_from_fork_asm+0x1a/0x30[ 8.516718]

CVE-2025-38554 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:mm: fix a UAF when vma->mm is freed after vma->vm_refcnt got droppedBy inducing delays in the right places, Jann Horn created a reproducer fora hard to hit UAF issue that became possible after VMAs were allowed to berecycled by adding SLAB_TYPESAFE_BY_RCU to their cache.Race description is borrowed from Jann's discovery report:lock_vma_under_rcu() looks up a VMA locklessly with mas_walk() underrcu_read_lock(). At that point, the VMA may be concurrently freed, and itcan be recycled by another process. vma_start_read() then increments thevma->vm_refcnt (if it is in an acceptable range), and if this succeeds,vma_start_read() can return a recycled VMA.In this scenario where the VMA has been recycled, lock_vma_under_rcu()will then detect the mismatching ->vm_mm pointer and drop the VMA throughvma_end_read(), which calls vma_refcount_put(). vma_refcount_put() dropsthe refcount and then calls rcuwait_wake_up() using a copy of vma->vm_mm. This is wrong: It implicitly assumes that the caller is keeping the VMA'smm alive, but in this scenario the caller has no relation to the VMA's mm,so the rcuwait_wake_up() can cause UAF.The diagram depicting the race:T1 T2 T3== == ==lock_vma_under_rcu mas_walk mmap vma_start_read __refcount_inc_not_zero_limited_acquire munmap __vma_enter_locked refcount_add_not_zero vma_end_read vma_refcount_put __refcount_dec_and_test rcuwait_wait_event rcuwait_wake_up [UAF]Note that rcuwait_wait_event() in T3 does not block because refcount wasalready dropped by T1. At this point T3 can exit and free the mm causingUAF in T1.To avoid this we move vma->vm_mm verification into vma_start_read() andgrab vma->vm_mm to stabilize it before vma_refcount_put() operation.[surenb@google.com: v3]

CVE-2025-38703 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:drm/xe: Make dma-fences compliant with the safe access rulesXe can free some of the data pointed to by the dma-fences it exports. Mostnotably the timeline name can get freed if userspace closes the associatedsubmit queue. At the same time the fence could have been exported to athird party (for example a sync_fence fd) which will then cause an use-after-free on subsequent access.To make this safe we need to make the driver compliant with the newlydocumented dma-fence rules. Driver has to ensure a RCU grace periodbetween signalling a fence and freeing any data pointed to by said fence.For the timeline name we simply make the queue be freed via kfree_rcu andfor the shared lock associated with multiple queues we add a RCU graceperiod before freeing the per GT structure holding the lock.

CVE-2025-39682 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:tls: fix handling of zero-length records on the rx_listEach recvmsg() call must process either - only contiguous DATA records (any number of them) - one non-DATA recordIf the next record has different type than what has already beenprocessed we break out of the main processing loop. If the recordhas already been decrypted (which may be the case for TLS 1.3 wherewe don't know type until decryption) we queue the pending recordto the rx_list. Next recvmsg() will pick it up from there.Queuing the skb to rx_list after zero-copy decrypt is not possible,since in that case we decrypted directly to the user space buffer,and we don't have an skb to queue (darg.skb points to the ciphertextskb for access to metadata like length).Only data records are allowed zero-copy, and we break the processingloop after each non-data record. So we should never zero-copy andthen find out that the record type has changed. The corner casewe missed is when the initial record comes from rx_list, and it'szero length.

Description: In the Linux kernel, the following vulnerability has been resolved:ipvs: Defer ip_vs_ftp unregister during netns cleanupOn the netns cleanup path, __ip_vs_ftp_exit() may unregister ip_vs_ftpbefore connections with valid cp->app pointers are flushed, leading to ause-after-free.Fix this by introducing a global `exiting_module` flag, set to true inip_vs_ftp_exit() before unregistering the pernet subsystem. In__ip_vs_ftp_exit(), skip ip_vs_ftp unregister if called during netnscleanup (when exiting_module is false) and defer it to__ip_vs_cleanup_batch(), which unregisters all apps after all connectionsare flushed. If called during module exit, unregister ip_vs_ftpimmediately.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: ufs: core: Fix data race in CPU latency PM QoS request handlingThe cpu_latency_qos_add/remove/update_request interfaces lack internalsynchronization by design, requiring the caller to ensure thread safety.The current implementation relies on the 'pm_qos_enabled' flag, which isinsufficient to prevent concurrent access and cannot serve as a propersynchronization mechanism. This has led to data races and listcorruption issues.A typical race condition call trace is:[Thread A]ufshcd_pm_qos_exit() --> cpu_latency_qos_remove_request() --> cpu_latency_qos_apply(); --> pm_qos_update_target() --> plist_del <--(1) delete plist node --> memset(req, 0, sizeof(*req)); --> hba->pm_qos_enabled = false;[Thread B]ufshcd_devfreq_target --> ufshcd_devfreq_scale --> ufshcd_scale_clks --> ufshcd_pm_qos_update <--(2) pm_qos_enabled is true --> cpu_latency_qos_update_request --> pm_qos_update_target --> plist_del <--(3) plist node use-after-freeIntroduces a dedicated mutex to serialize PM QoS operations, preventingdata races and ensuring safe access to PM QoS resources, including sysfsinterface reads.

Both scenarios can then pass thevalidation successfully.This doesn't happen with valid XSk applications, but can be usedto perform attacks.Always promote desc->len to ``u64`` first to exclude positiveoverflows of it. Use explicit check_{add,sub}_overflow() whenvalidating desc->addr (which is ``u64`` already).bloat-o-meter reports a little growth of the code size:add/remove: 0/0 grow/shrink: 2/1 up/down: 60/-16 (44)Function old new deltaxskq_cons_peek_desc 299 330 +31xsk_tx_peek_release_desc_batch 973 1002 +29xsk_generic_xmit 3148 3132 -16but hopefully this doesn't hurt the performance much.

Description: In the Linux kernel, the following vulnerability has been resolved:tls: wait for pending async decryptions if tls_strp_msg_hold failsAsync decryption calls tls_strp_msg_hold to create a clone of theinput skb to hold references to the memory it uses. If we fail toallocate that clone, proceeding with async decryption can lead tovarious issues (UAF on the skb, writing into userspace memory afterthe recv() call has returned).In this case, wait for all pending decryption requests.

CVE-2025-40214 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:af_unix: Initialise scc_index in unix_add_edge().Quang Le reported that the AF_UNIX GC could garbage-collect areceive queue of an alive in-flight socket, with a nice repro.The repro consists of three stages. 1) 1-a. Create a single cyclic reference with many sockets 1-b. close() all sockets 1-c. Trigger GC 2) 2-a. Pass sk-A to an embryo sk-B 2-b. Pass sk-X to sk-X 2-c. Trigger GC 3) 3-a. accept() the embryo sk-B 3-b. Pass sk-B to sk-C 3-c. close() the in-flight sk-A 3-d. Trigger GCAs of 2-c, sk-A and sk-X are linked to unix_unvisited_vertices,and unix_walk_scc() groups them into two different SCCs: unix_sk(sk-A)->vertex->scc_index = 2 (UNIX_VERTEX_INDEX_START) unix_sk(sk-X)->vertex->scc_index = 3Once GC completes, unix_graph_grouped is set to true.Also, unix_graph_maybe_cyclic is set to true due to sk-X'scyclic self-reference, which makes close() trigger GC.At 3-b, unix_add_edge() allocates unix_sk(sk-B)->vertex andlinks it to unix_unvisited_vertices.unix_update_graph() is called at 3-a. and 3-b., but neitherunix_graph_grouped nor unix_graph_maybe_cyclic is changedbecause both sk-B's listener and sk-C are not in-flight.3-c decrements sk-A's file refcnt to 1.Since unix_graph_grouped is true at 3-d, unix_walk_scc_fast()is finally called and iterates 3 sockets sk-A, sk-B, and sk-X: sk-A -> sk-B (-> sk-C) sk-X -> sk-XThis is totally fine. All of them are not yet close()d andshould be grouped into different SCCs.However, unix_vertex_dead() misjudges that sk-A and sk-B arein the same SCC and sk-A is dead. unix_sk(sk-A)->scc_index == unix_sk(sk-B)->scc_index <-- Wrong! && sk-A's file refcnt == unix_sk(sk-A)->vertex->out_degree ^-- 1 in-flight count for sk-B -> sk-A is dead !?The problem is that unix_add_edge() does not initialise scc_index.Stage 1) is used for heap spraying, making a newly allocatedvertex have vertex->scc_index == 2 (UNIX_VERTEX_INDEX_START)set by unix_walk_scc() at 1-c.Let's track the max SCC index from the previous unix_walk_scc()call and assign the max + 1 to a new vertex's scc_index.This way, we can continue to avoid Tarjan's algorithm whilepreventing misjudgments.

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

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

CVE-2025-40297 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:net: bridge: fix use-after-free due to MST port state bypasssyzbot reported[1] a use-after-free when deleting an expired fdb. It isdue to a race condition between learning still happening and a port beingdeleted, after all its fdbs have been flushed. The port's state has beentoggled to disabled so no learning should happen at that time, but if wehave MST enabled, it will bypass the port's state, that together with VLANfiltering disabled can lead to fdb learning at a time when it shouldn'thappen while the port is being deleted. VLAN filtering must be disabledbecause we flush the port VLANs when it's being deleted which will stoplearning. This fix adds a check for the port's vlan group which isinitialized to NULL when the port is getting deleted, that avoids the portstate bypass. When MST is enabled there would be a minimal new overheadin the fast-path because the port's vlan group pointer is cache-hot.[1] https://syzkaller.appspot.com/bug?extid=dd280197f0f7ab3917be

CVE-2025-40362 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:ceph: fix multifs mds auth caps issueThe mds auth caps check should also validate thefsname along with the associated caps. Not doingso would result in applying the mds auth caps ofone fs on to the other fs in a multifs ceph cluster.The bug causes multiple issues w.r.t userauthentication, following is one such example.Steps to Reproduce (on vstart cluster):1. Create two file systems in a cluster, say 'fsname1' and 'fsname2'2. Authorize read only permission to the user 'client.usr' on fs 'fsname1' $ceph fs authorize fsname1 client.usr / r3. Authorize read and write permission to the same user 'client.usr' on fs 'fsname2' $ceph fs authorize fsname2 client.usr / rw4. Update the keyring $ceph auth get client.usr >> ./keyringWith above permssions for the user 'client.usr', following is theexpectation. a. The 'client.usr' should be able to only read the contents and not allowed to create or delete files on file system 'fsname1'. b. The 'client.usr' should be able to read/write on file system 'fsname2'.But, with this bug, the 'client.usr' is allowed to read/write on filesystem 'fsname1'. See below.5. Mount the file system 'fsname1' with the user 'client.usr' $sudo bin/mount.ceph usr@.fsname1=/ /kmnt_fsname1_usr/6. Try creating a file on file system 'fsname1' with user 'client.usr'. This should fail but passes with this bug. $touch /kmnt_fsname1_usr/file17. Mount the file system 'fsname1' with the user 'client.admin' and create a file. $sudo bin/mount.ceph admin@.fsname1=/ /kmnt_fsname1_admin $echo "data" > /kmnt_fsname1_admin/admin_file18. Try removing an existing file on file system 'fsname1' with the user 'client.usr'. This shoudn't succeed but succeeds with the bug. $rm -f /kmnt_fsname1_usr/admin_file1For more information, please take a look at the corresponding mds/fuse patchand tests added by looking into the tracker mentioned below.v2: Fix a possible null dereference in doutcv3: Don't store fsname from mdsmap, validate against ceph_mount_options's fsname and use itv4: Code refactor, better warning message and fix possible compiler warning[ Slava.Dubeyko: "fsname check failed" -> "fsname mismatch" ]

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:erofs: avoid using multiple devices with different typeFor multiple devices, both primary and extra devices should be thesame type. `erofs_init_device` has already guaranteed that if theprimary is a file-backed device, extra devices should also beregular files.However, if the primary is a block device while the extra deviceis a file-backed device, `erofs_init_device` will get an ENOTBLK,which is not treated as an error in `erofs_fc_get_tree`, and thatleads to an UAF: erofs_fc_get_tree get_tree_bdev_flags(erofs_fc_fill_super) erofs_read_superblock erofs_init_device // sbi->dif0 is not inited yet, // return -ENOTBLK deactivate_locked_super free(sbi) if (err is -ENOTBLK) sbi->dif0.file = filp_open() // sbi UAFSo if -ENOTBLK is hitted in `erofs_init_device`, it means theprimary device must be a block device, and the extra deviceis not a block device.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:perf: Revert to requiring CAP_SYS_ADMIN for uprobesJann reports that uprobes can be used destructively when used in themiddle of an instruction. The kernel only verifies there is a validinstruction at the requested offset, but due to variable instructionlength cannot determine if this is an instruction as seen by theintended execution stream.Additionally, Mark Rutland notes that on architectures that mix datain the text segment (like arm64), a similar things can be done if thedata word is 'mistaken' for an instruction.As such, require CAP_SYS_ADMIN for uprobes.

Description: In the Linux kernel, the following vulnerability has been resolved:HID: core: Harden s32ton() against conversion to 0 bitsTesting by the syzbot fuzzer showed that the HID core gets ashift-out-of-bounds exception when it tries to convert a 32-bitquantity to a 0-bit quantity. Ideally this should never occur, butthere are buggy devices and some might have a report field with sizeset to zero; we shouldn't reject the report or the device just becauseof that.Instead, harden the s32ton() routine so that it returns a reasonableresult instead of crashing when it is called with the number of bitsset to 0 -- the same as what snto32() does.

CVE-2025-38628 Severity: Moderate CVSS3 score: 6.6

Description: In the Linux kernel, the following vulnerability has been resolved:vdpa/mlx5: Fix release of uninitialized resources on error pathThe commit in the fixes tag made sure that mlx5_vdpa_free()is the single entrypoint for removing the vdpa device resourcesadded in mlx5_vdpa_dev_add(), even in the cleanup path ofmlx5_vdpa_dev_add().This means that all functions from mlx5_vdpa_free() should be able tohandle uninitialized resources. This was not the case though:mlx5_vdpa_destroy_mr_resources() and mlx5_cmd_cleanup_async_ctx()were not able to do so. This caused the splat below when addinga vdpa device without a MAC address.This patch fixes these remaining issues:- Makes mlx5_vdpa_destroy_mr_resources() return early if called on uninitialized resources.- Moves mlx5_cmd_init_async_ctx() early on during device addition because it can't fail. This means that mlx5_cmd_cleanup_async_ctx() also can't fail. To mirror this, move the call site of mlx5_cmd_cleanup_async_ctx() in mlx5_vdpa_free().An additional comment was added in mlx5_vdpa_free() to documentthe expectations of functions called from this context.Splat: mlx5_core 0000:b5:03.2: mlx5_vdpa_dev_add:3950:(pid 2306) warning: No mac address provisioned? ------------[ cut here ]------------ WARNING: CPU: 13 PID: 2306 at kernel/workqueue.c:4207 __flush_work+0x9a/0xb0 [...] Call Trace: ? __try_to_del_timer_sync+0x61/0x90 ? __timer_delete_sync+0x2b/0x40 mlx5_vdpa_destroy_mr_resources+0x1c/0x40 [mlx5_vdpa] mlx5_vdpa_free+0x45/0x160 [mlx5_vdpa] vdpa_release_dev+0x1e/0x50 [vdpa] device_release+0x31/0x90 kobject_cleanup+0x37/0x130 mlx5_vdpa_dev_add+0x327/0x890 [mlx5_vdpa] vdpa_nl_cmd_dev_add_set_doit+0x2c1/0x4d0 [vdpa] genl_family_rcv_msg_doit+0xd8/0x130 genl_family_rcv_msg+0x14b/0x220 ? __pfx_vdpa_nl_cmd_dev_add_set_doit+0x10/0x10 [vdpa] genl_rcv_msg+0x47/0xa0 ? __pfx_genl_rcv_msg+0x10/0x10 netlink_rcv_skb+0x53/0x100 genl_rcv+0x24/0x40 netlink_unicast+0x27b/0x3b0 netlink_sendmsg+0x1f7/0x430 __sys_sendto+0x1fa/0x210 ? ___pte_offset_map+0x17/0x160 ? next_uptodate_folio+0x85/0x2b0 ? percpu_counter_add_batch+0x51/0x90 ? filemap_map_pages+0x515/0x660 __x64_sys_sendto+0x20/0x30 do_syscall_64+0x7b/0x2c0 ? do_read_fault+0x108/0x220 ? do_pte_missing+0x14a/0x3e0 ? __handle_mm_fault+0x321/0x730 ? count_memcg_events+0x13f/0x180 ? handle_mm_fault+0x1fb/0x2d0 ? do_user_addr_fault+0x20c/0x700 ? syscall_exit_work+0x104/0x140 entry_SYSCALL_64_after_hwframe+0x76/0x7e RIP: 0033:0x7f0c25b0feca [...] ---[ end trace 0000000000000000 ]---

Description: In the Linux kernel, the following vulnerability has been resolved:can: kvaser_pciefd: refine error prone echo_skb_max handling logicecho_skb_max should define the supported upper limit of echo_skb[]allocated inside the netdevice's priv. The corresponding size valueprovided by this driver to alloc_candev() is KVASER_PCIEFD_CAN_TX_MAX_COUNTwhich is 17.But later echo_skb_max is rounded up to the nearest power of two (for themax case, that would be 32) and the tx/ack indices calculated furtherduring tx/rx may exceed the upper array boundary. Kasan reported this forthe ack case inside kvaser_pciefd_handle_ack_packet(), though the xmitfunction has actually caught the same thing earlier.

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

CVE-2025-38349 Severity: Moderate CVSS3 score: 6.5

Description: In the Linux kernel, the following vulnerability has been resolved:eventpoll: don't decrement ep refcount while still holding the ep mutexJann Horn points out that epoll is decrementing the ep refcount and thendoing a mutex_unlock(&ep->mtx);afterwards. That's very wrong, because it can lead to a use-after-free.That pattern is actually fine for the very last reference, because thecode in question will delay the actual call to "ep_free(ep)" until afterit has unlocked the mutex.But it's wrong for the much subtler "next to last" case when somebody*else* may also be dropping their reference and free the ep while we'restill using the mutex.Note that this is true even if that other user is also using the same epmutex: mutexes, unlike spinlocks, can not be used for object ownership,even if they guarantee mutual exclusion.A mutex "unlock" operation is not atomic, and as one user is stillaccessing the mutex as part of unlocking it, another user can come inand get the now released mutex and free the data structure while thefirst user is still cleaning up.See our mutex documentation in Documentation/locking/mutex-design.rst,in particular the section [1] about semantics: "mutex_unlock() may access the mutex structure even after it has internally released the lock already - so it's not safe for another context to acquire the mutex and assume that the mutex_unlock() context is not using the structure anymore"So if we drop our ep ref before the mutex unlock, but we weren't thelast one, we may then unlock the mutex, another user comes in, drops_their_ reference and releases the 'ep' as it now has no users - allwhile the mutex_unlock() is still accessing it.Fix this by simply moving the ep refcount dropping to outside the mutex:the refcount itself is atomic, and doesn't need mutex protection (that'sthe whole _point_ of refcounts: unlike mutexes, they are inherentlyabout object lifetimes).

CVE-2025-40300 Severity: Moderate CVSS3 score: 6.5

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

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

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

CVE-2025-9232 Severity: Moderate CVSS3 score: 6.5

Description: Issue summary: An application using the OpenSSL HTTP client API functions maytrigger an out-of-bounds read if the 'no_proxy' environment variable is set andthe host portion of the authority component of the HTTP URL is an IPv6 address.Impact summary: An out-of-bounds read can trigger a crash which leads toDenial of Service for an application.The OpenSSL HTTP client API functions can be used directly by applicationsbut they are also used by the OCSP client functions and CMP (CertificateManagement Protocol) client implementation in OpenSSL. However the URLs usedby these implementations are unlikely to be controlled by an attacker.In this vulnerable code the out of bounds read can only trigger a crash.Furthermore the vulnerability requires an attacker-controlled URL to bepassed from an application to the OpenSSL function and the user has to havea 'no_proxy' environment variable set. For the aforementioned reasons theissue was assessed as Low severity.The vulnerable code was introduced in the following patch releases:3.0.16, 3.1.8, 3.2.4, 3.3.3, 3.4.0 and 3.5.0.The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by thisissue, as the HTTP client implementation is outside the OpenSSL FIPS moduleboundary.

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

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

CVE-2025-38709 Severity: Moderate CVSS3 score: 6.4

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

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

CVE-2025-39945 Severity: Moderate CVSS3 score: 6.4

Description: In the Linux kernel, the following vulnerability has been resolved:cnic: Fix use-after-free bugs in cnic_delete_taskThe original code uses cancel_delayed_work() in cnic_cm_stop_bnx2x_hw(),which does not guarantee that the delayed work item 'delete_task' hasfully completed if it was already running. Additionally, the delayed workitem is cyclic, the flush_workqueue() in cnic_cm_stop_bnx2x_hw() onlyblocks and waits for work items that were already queued to theworkqueue prior to its invocation. Any work items submitted afterflush_workqueue() is called are not included in the set of tasks that theflush operation awaits. This means that after the cyclic work items havefinished executing, a delayed work item may still exist in the workqueue.This leads to use-after-free scenarios where the cnic_dev is deallocatedby cnic_free_dev(), while delete_task remains active and attempt todereference cnic_dev in cnic_delete_task().A typical race condition is illustrated below:CPU 0 (cleanup) | CPU 1 (delayed work callback)cnic_netdev_event() | cnic_stop_hw() | cnic_delete_task() cnic_cm_stop_bnx2x_hw() | ... cancel_delayed_work() | /* the queue_delayed_work() flush_workqueue() | executes after flush_workqueue()*/ | queue_delayed_work() cnic_free_dev(dev)//free | cnic_delete_task() //new instance | dev = cp->dev; //useReplace cancel_delayed_work() with cancel_delayed_work_sync() to ensurethat the cyclic delayed work item is properly canceled and that anyongoing execution of the work item completes before the cnic_dev isdeallocated. Furthermore, since cancel_delayed_work_sync() uses__flush_work(work, true) to synchronously wait for any currentlyexecuting instance of the work item to finish, the flush_workqueue()becomes redundant and should be removed.This bug was identified through static analysis. To reproduce the issueand validate the fix, I simulated the cnic PCI device in QEMU andintroduced intentional delays - such as inserting calls to ssleep()within the cnic_delete_task() function - to increase the likelihoodof triggering the bug.

Description: In the Linux kernel, the following vulnerability has been resolved:nvmet-fc: avoid scheduling association deletion twiceWhen forcefully shutting down a port via the configfs interface,nvmet_port_subsys_drop_link() first calls nvmet_port_del_ctrls() andthen nvmet_disable_port(). Both functions will eventually schedule allremaining associations for deletion.The current implementation checks whether an association is about to beremoved, but only after the work item has already been scheduled. As aresult, it is possible for the first scheduled work item to free allresources, and then for the same work item to be scheduled again fordeletion.Because the association list is an RCU list, it is not possible to takea lock and remove the list entry directly, so it cannot be looked upagain. Instead, a flag (terminating) must be used to determine whetherthe association is already in the process of being deleted.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:perf/core: Handle buffer mapping fail correctly in perf_mmap()After successful allocation of a buffer or a successful attachment to anexisting buffer perf_mmap() tries to map the buffer read only into the pagetable. If that fails, the already set up page table entries are zapped, butthe other perf specific side effects of that failure are not handled. Thecalling code just cleans up the VMA and does not invoke perf_mmap_close().This leaks reference counts, corrupts user->vm accounting and also resultsin an unbalanced invocation of event::event_mapped().Cure this by moving the event::event_mapped() invocation before themap_range() call so that on map_range() failure perf_mmap_close() can beinvoked without causing an unbalanced event::event_unmapped() call.perf_mmap_close() undoes the reference counts and eventually frees buffers.

Description: In the Linux kernel, the following vulnerability has been resolved:genetlink: fix genl_bind() invoking bind() after -EPERMPer family bind/unbind callbacks were introduced to allow familiesto track multicast group consumer presence, e.g. to start or stopproducing events depending on listeners.However, in genl_bind() the bind() callback was invoked even ifcapability checks failed and ret was set to -EPERM. This means thatcallbacks could run on behalf of unauthorized callers while thesyscall still returned failure to user space.Fix this by only invoking bind() after "if (ret) break;" checki.e. after permission checks have succeeded.

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

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

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

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

CVE-2025-15469 Severity: Moderate CVSS3 score: 6.2

Description: Issue summary: The 'openssl dgst' command-line tool silently truncates inputdata to 16MB when using one-shot signing algorithms and reports success insteadof an error.Impact summary: A user signing or verifying files larger than 16MB withone-shot algorithms (such as Ed25519, Ed448, or ML-DSA) may believe the entirefile is authenticated while trailing data beyond 16MB remains unauthenticated.When the 'openssl dgst' command is used with algorithms that only supportone-shot signing (Ed25519, Ed448, ML-DSA-44, ML-DSA-65, ML-DSA-87), the inputis buffered with a 16MB limit. If the input exceeds this limit, the toolsilently truncates to the first 16MB and continues without signaling an error,contrary to what the documentation states. This creates an integrity gap wheretrailing bytes can be modified without detection if both signing andverification are performed using the same affected codepath.The issue affects only the command-line tool behavior. Verifiers that processthe full message using library APIs will reject the signature, so the riskprimarily affects workflows that both sign and verify with the affected'openssl dgst' command. Streaming digest algorithms for 'openssl dgst' andlibrary users are unaffected.The FIPS modules in 3.5 and 3.6 are not affected by this issue, as thecommand-line tools are outside the OpenSSL FIPS module boundary.OpenSSL 3.5 and 3.6 are vulnerable to this issue.OpenSSL 3.4, 3.3, 3.0, 1.1.1 and 1.0.2 are not affected by this issue.

Description: AIDE is an advanced intrusion detection environment. Prior to version 0.19.2, there is an improper output neutralization vulnerability in AIDE. An attacker can craft a malicious filename by including terminal escape sequences to hide the addition or removal of the file from the report and/or tamper with the log output. A local user might exploit this to bypass the AIDE detection of malicious files. Additionally the output of extended attribute key names and symbolic links targets are also not properly neutralized. This issue has been patched in version 0.19.2. A workaround involves configuring AIDE to write the report output to a regular file, redirecting stdout to a regular file, or redirecting the log output written to stderr to a regular file.

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

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

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

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

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

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

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

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

CVE-2024-53138 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5e: kTLS, Fix incorrect page refcountingThe kTLS tx handling code is using a mix of get_page() andpage_ref_inc() APIs to increment the page reference. But on the releasepath (mlx5e_ktls_tx_handle_resync_dump_comp()), only put_page() is used.This is an issue when using pages from large folios: the get_page()references are stored on the folio page while the page_ref_inc()references are stored directly in the given page. On release the foliopage will be dereferenced too many times.This was found while doing kTLS testing with sendfile() + ZC when theserved file was read from NFS on a kernel with NFS large folios support(commit 49b29a573da8 ("nfs: add support for large folios")).

CVE-2025-38149 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:net: phy: clear phydev->devlink when the link is deletedThere is a potential crash issue when disabling and re-enabling thenetwork port. When disabling the network port, phy_detach() callsdevice_link_del() to remove the device link, but it does not clearphydev->devlink, so phydev->devlink is not a NULL pointer. Then thenetwork port is re-enabled, but if phy_attach_direct() fails beforecalling device_link_add(), the code jumps to the "error" label andcalls phy_detach(). Since phydev->devlink retains the old value fromthe previous attach/detach cycle, device_link_del() uses the old value,which accesses a NULL pointer and causes a crash. The simplified crashlog is as follows.[ 24.702421] Call trace:[ 24.704856] device_link_put_kref+0x20/0x120[ 24.709124] device_link_del+0x30/0x48[ 24.712864] phy_detach+0x24/0x168[ 24.716261] phy_attach_direct+0x168/0x3a4[ 24.720352] phylink_fwnode_phy_connect+0xc8/0x14c[ 24.725140] phylink_of_phy_connect+0x1c/0x34Therefore, phydev->devlink needs to be cleared when the device link isdeleted.

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/cma: Fix hang when cma_netevent_callback fails to queue_workThe cited commit fixed a crash when cma_netevent_callback was called fora cma_id while work on that id from a previous call had not yet started.The work item was re-initialized in the second call, which corrupted thework item currently in the work queue.However, it left a problem when queue_work fails (because the item isstill pending in the work queue from a previous call). In this case,cma_id_put (which is called in the work handler) is therefore notcalled. This results in a userspace process hang (zombie process).Fix this by calling cma_id_put() if queue_work fails.

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

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

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

CVE-2025-38413 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:virtio-net: xsk: rx: fix the frame's length checkWhen calling buf_to_xdp, the len argument is the frame data's lengthwithout virtio header's length (vi->hdr_len). We check that len with xsk_pool_get_rx_frame_size() + vi->hdr_lento ensure the provided len does not larger than the allocated chunksize. The additional vi->hdr_len is because in virtnet_add_recvbuf_xsk,we use part of XDP_PACKET_HEADROOM for virtio header and ask the vhostto start placing data from hard_start + XDP_PACKET_HEADROOM - vi->hdr_lennot hard_start + XDP_PACKET_HEADROOMBut the first buffer has virtio_header, so the maximum frame's length inthe first buffer can only be xsk_pool_get_rx_frame_size()not xsk_pool_get_rx_frame_size() + vi->hdr_lenlike in the current check.This commit adds an additional argument to buf_to_xdp differentiatebetween the first buffer and other ones to correctly calculate the maximumframe's length.

CVE-2025-38463 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:tcp: Correct signedness in skb remaining space calculationSyzkaller reported a bug [1] where sk->sk_forward_alloc can overflow.When we send data, if an skb exists at the tail of the write queue, thekernel will attempt to append the new data to that skb. However, the codethat checks for available space in the skb is flawed:'''copy = size_goal - skb->len'''The types of the variables involved are:'''copy: ssize_t (s64 on 64-bit systems)size_goal: intskb->len: unsigned int'''Due to C's type promotion rules, the signed size_goal is converted to anunsigned int to match skb->len before the subtraction. The result is anunsigned int.When this unsigned int result is then assigned to the s64 copy variable,it is zero-extended, preserving its non-negative value. Consequently, copyis always >= 0.Assume we are sending 2GB of data and size_goal has been adjusted to avalue smaller than skb->len. The subtraction will result in copy holding avery large positive integer. In the subsequent logic, this large value isused to update sk->sk_forward_alloc, which can easily cause it to overflow.The syzkaller reproducer uses TCP_REPAIR to reliably create thiscondition. However, this can also occur in real-world scenarios. Thetcp_bound_to_half_wnd() function can also reduce size_goal to a smallvalue. This would cause the subsequent tcp_wmem_schedule() to setsk->sk_forward_alloc to a value close to INT_MAX. Further memoryallocation requests would then cause sk_forward_alloc to wrap around andbecome negative.[1]: https://syzkaller.appspot.com/bug?extid=de6565462ab540f50e47

Description: In the Linux kernel, the following vulnerability has been resolved:spi: stm32: Check for cfg availability in stm32_spi_probeThe stm32_spi_probe function now includes a check to ensure that thepointer returned by of_device_get_match_data is not NULL beforeaccessing its members. This resolves a warning where a potential NULLpointer dereference could occur when accessing cfg->has_device_mode.Before accessing the 'has_device_mode' member, we verify that 'cfg' isnot NULL. If 'cfg' is NULL, an error message is logged.This change ensures that the driver does not attempt to accessconfiguration data if it is not available, thus preventing a potentialsystem crash due to a NULL pointer dereference.

CVE-2025-39716 Severity: Moderate CVSS3 score: 6.1

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

CVE-2025-39791 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:dm: dm-crypt: Do not partially accept write BIOs with zoned targetsRead and write operations issued to a dm-crypt target may be splitaccording to the dm-crypt internal limits defined by the max_read_sizeand max_write_size module parameters (default is 128 KB). The intent isto improve processing time of large BIOs by splitting them into smalleroperations that can be parallelized on different CPUs.For zoned dm-crypt targets, this BIO splitting is still done but withoutthe parallel execution to ensure that the issuing order of writeoperations to the underlying devices remains sequential. However, thesplitting itself causes other problems:1) Since dm-crypt relies on the block layer zone write plugging to handle zone append emulation using regular write operations, the reminder of a split write BIO will always be plugged into the target zone write plugged. Once the on-going write BIO finishes, this reminder BIO is unplugged and issued from the zone write plug work. If this reminder BIO itself needs to be split, the reminder will be re-issued and plugged again, but that causes a call to a blk_queue_enter(), which may block if a queue freeze operation was initiated. This results in a deadlock as DM submission still holds BIOs that the queue freeze side is waiting for.2) dm-crypt relies on the emulation done by the block layer using regular write operations for processing zone append operations. This still requires to properly return the written sector as the BIO sector of the original BIO. However, this can be done correctly only and only if there is a single clone BIO used for processing the original zone append operation issued by the user. If the size of a zone append operation is larger than dm-crypt max_write_size, then the orginal BIO will be split and processed as a chain of regular write operations. Such chaining result in an incorrect written sector being returned to the zone append issuer using the original BIO sector. This in turn results in file system data corruptions using xfs or btrfs.Fix this by modifying get_max_request_size() to always return the sizeof the BIO to avoid it being split with dm_accpet_partial_bio() incrypt_map(). get_max_request_size() is renamed toget_max_request_sectors() to clarify the unit of the value returnedand its interface is changed to take a struct dm_target pointer and apointer to the struct bio being processed. In addition to this change,to ensure that crypt_alloc_buffer() works correctly, set the dm-cryptdevice max_hw_sectors limit to be at mostBIO_MAX_VECS << PAGE_SECTORS_SHIFT (1 MB with a 4KB page architecture).This forces DM core to split write BIOs before passing them tocrypt_map(), and thus guaranteeing that dm-crypt can always accept anentire write BIO without needing to split it.This change does not have any effect on the read path of dm-crypt. Readoperations can still be split and the BIO fragments processed inparallel. There is also no impact on the performance of the write pathgiven that all zone write BIOs were already processed inline instead ofin parallel.This change also does not affect in any way regular dm-crypt blockdevices.

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

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

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

In particular the inode numberis that of a symbolic link, rather than a directory.Squashfs_get_parent() gets called with that symbolic link inode, andaccesses the parent member field. unsigned int parent_ino = squashfs_i(inode)->parent;Because non-directory inodes in Squashfs do not have a parent value, thisis uninitialised, and this causes an uninitialised value access.The fix is to initialise parent with the invalid inode 0, which will causean EINVAL error to be returned.Regular inodes used to share the parent field with the block_list_startfield. This is removed in this commit to enable the parent field tocontain the invalid inode number 0.

CVE-2025-40118 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: pm80xx: Fix array-index-out-of-of-bounds on rmmodSince commit f7b705c238d1 ("scsi: pm80xx: Set phy_attached to zero whendevice is gone") UBSAN reports: UBSAN: array-index-out-of-bounds in drivers/scsi/pm8001/pm8001_sas.c:786:17 index 28 is out of range for type 'pm8001_phy [16]'on rmmod when using an expander.For a direct attached device, attached_phy contains the local phy id.For a device behind an expander, attached_phy contains the remote phyid, not the local phy id.I.e. while pm8001_ha will have pm8001_ha->chip->n_phy local phys, for adevice behind an expander, attached_phy can be much larger thanpm8001_ha->chip->n_phy (depending on the amount of phys of theexpander).E.g. on my system pm8001_ha has 8 phys with phy ids 0-7. One of theports has an expander connected. The expander has 31 phys with phy ids0-30.The pm8001_ha->phy array only contains the phys of the HBA. It does notcontain the phys of the expander. Thus, it is wrong to use attached_phyto index the pm8001_ha->phy array for a device behind an expander.Thus, we can only clear phy_attached for devices that are directlyattached.

Description: In the Linux kernel, the following vulnerability has been resolved:sparc: fix accurate exception reporting in copy_{from_to}_user for UltraSPARCThe referenced commit introduced exception handlers on user-space memoryreferences in copy_from_user and copy_to_user. These handlers return fromthe respective function and calculate the remaining bytes left to copyusing the current register contents. This commit fixes a couple of badcalculations. This will fix the return value of copy_from_user andcopy_to_user in the faulting case. The behaviour of memcpy stays unchanged.

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

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

Because the kernelexecutes XRSTOR with the guest's XFD, saving XSTATE_BV[i]=1 with XFD[i]=1will cause XRSTOR to #NM and panic the kernel.E.g. if fpu_update_guest_xfd() sets XFD without clearing XSTATE_BV: ------------[ cut here ]------------ WARNING: arch/x86/kernel/traps.c:1524 at exc_device_not_available+0x101/0x110, CPU#29: amx_test/848 Modules linked in: kvm_intel kvm irqbypass CPU: 29 UID: 1000 PID: 848 Comm: amx_test Not tainted 6.19.0-rc2-ffa07f7fd437-x86_amx_nm_xfd_non_init-vm #171 NONE Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 RIP: 0010:exc_device_not_available+0x101/0x110 Call Trace: asm_exc_device_not_available+0x1a/0x20 RIP: 0010:restore_fpregs_from_fpstate+0x36/0x90 switch_fpu_return+0x4a/0xb0 kvm_arch_vcpu_ioctl_run+0x1245/0x1e40 [kvm] kvm_vcpu_ioctl+0x2c3/0x8f0 [kvm] __x64_sys_ioctl+0x8f/0xd0 do_syscall_64+0x62/0x940 entry_SYSCALL_64_after_hwframe+0x4b/0x53 ---[ end trace 0000000000000000 ]---This can happen if the guest executes WRMSR(MSR_IA32_XFD) to set XFD[18] = 1,and a host IRQ triggers kernel_fpu_begin() prior to the vmexit handler'scall to fpu_update_guest_xfd().and if userspace stuffs XSTATE_BV[i]=1 via KVM_SET_XSAVE: ------------[ cut here ]------------ WARNING: arch/x86/kernel/traps.c:1524 at exc_device_not_available+0x101/0x110, CPU#14: amx_test/867 Modules linked in: kvm_intel kvm irqbypass CPU: 14 UID: 1000 PID: 867 Comm: amx_test Not tainted 6.19.0-rc2-2dace9faccd6-x86_amx_nm_xfd_non_init-vm #168 NONE Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 RIP: 0010:exc_device_not_available+0x101/0x110 Call Trace: asm_exc_device_not_available+0x1a/0x20 RIP: 0010:restore_fpregs_from_fpstate+0x36/0x90 fpu_swap_kvm_fpstate+0x6b/0x120 kvm_load_guest_fpu+0x30/0x80 [kvm] kvm_arch_vcpu_ioctl_run+0x85/0x1e40 [kvm] kvm_vcpu_ioctl+0x2c3/0x8f0 [kvm] __x64_sys_ioctl+0x8f/0xd0 do_syscall_64+0x62/0x940 entry_SYSCALL_64_after_hwframe+0x4b/0x53 ---[ end trace 0000000000000000 ]---The new behavior is consistent with the AMX architecture. Per Intel's SDM,XSAVE saves XSTATE_BV as '0' for components that are disabled via XFD(and non-compacted XSAVE saves the initial configuration of the statecomponent): If XSAVE, XSAVEC, XSAVEOPT, or XSAVES is saving the state component i, the instruction does not generate #NM when XCR0[i] = IA32_XFD[i] = 1; instead, it operates as if XINUSE[i] = 0 (and the state component was in its initial state): it saves bit i of XSTATE_BV field of the XSAVE header as 0; in addition, XSAVE saves the initial configuration of the state component (the other instructions do not save state component i).Alternatively, KVM could always do XRSTOR with XFD=0, e.g. by usinga constant XFD based on the set of enabled features when XSAVEing fora struct fpu_guest. However, having XSTATE_BV[i]=1 for XFD-disabledfeatures can only happen in the above interrupt case, or in similarscenarios involving preemption on preemptible kernels, becausefpu_swap_kvm_fpstate()'s call to save_fpregs_to_fpstate() saves theoutgoing FPU state with the current XFD; and that is (on all but thefirst WRMSR to XFD) the guest XFD.Therefore, XFD can only go out of sync with XSTATE_BV in the aboveinterrupt case, or in similar scenarios involving preemption onpreemptible kernels, and it we can consider it (de facto) part of KVMABI that KVM_GET_XSAVE returns XSTATE_BV[i]=0 for XFD-disabled features.[Move clea---truncated---

Consequently, during the end_buffer_read_sync()process, calling put_bh() may result in stack overrun.If the bh is not allocated on the stack, it belongs to a folio. Freeinga buffer head which belongs to a folio is done by drop_buffers() whichwill fail to free buffers which are still locked. So it is safe to callput_bh() before __end_buffer_read_notouch().

CVE-2025-40292 Severity: Moderate CVSS3 score: 6.0

Description: In the Linux kernel, the following vulnerability has been resolved:virtio-net: fix received length check in big packetsSince commit 4959aebba8c0 ("virtio-net: use mtu size as buffer lengthfor big packets"), when guest gso is off, the allocated size for bigpackets is not MAX_SKB_FRAGS * PAGE_SIZE anymore but depends onnegotiated MTU. The number of allocated frags for big packets is storedin vi->big_packets_num_skbfrags.Because the host announced buffer length can be malicious (e.g. the hostvhost_net driver's get_rx_bufs is modified to announce incorrectlength), we need a check in virtio_net receive path. Currently, thecheck is not adapted to the new change which can lead to NULL pagepointer dereference in the below while loop when receiving length thatis larger than the allocated one.This commit fixes the received length check corresponding to the newchange.

CVE-2025-68208 Severity: Moderate CVSS3 score: 6.0

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

If the item was from the pre-allocatedpool, calling kfree() on it is a bug that can lead to memory corruption.Fix this by using the correct deallocation function,qla24xx_free_purex_item(), which properly handles both dynamicallyallocated and pre-allocated items.

CVE-2025-39797 Severity: Moderate CVSS3 score: 5.9

Description: In the Linux kernel, the following vulnerability has been resolved:xfrm: Duplicate SPI HandlingThe issue originates when Strongswan initiates an XFRM_MSG_ALLOCSPINetlink message, which triggers the kernel function xfrm_alloc_spi().This function is expected to ensure uniqueness of the Security ParameterIndex (SPI) for inbound Security Associations (SAs). However, it canreturn success even when the requested SPI is already in use, leadingto duplicate SPIs assigned to multiple inbound SAs, differentiatedonly by their destination addresses.This behavior causes inconsistencies during SPI lookups for inbound packets.Since the lookup may return an arbitrary SA among those with the same SPI,packet processing can fail, resulting in packet drops.According to RFC 4301 section 4.4.2 , for inbound processing a unicast SAis uniquely identified by the SPI and optionally protocol.Reproducing the Issue Reliably:To consistently reproduce the problem, restrict the available SPI range incharon.conf : spi_min = 0x10000000 spi_max = 0x10000002This limits the system to only 2 usable SPI values.Next, create more than 2 Child SA. each using unique pair of src/dst address.As soon as the 3rd Child SA is initiated, it will be assigned a duplicateSPI, since the SPI pool is already exhausted.With a narrow SPI range, the issue is consistently reproducible.With a broader/default range, it becomes rare and unpredictable.Current implementation:xfrm_spi_hash() lookup function computes hash using daddr, proto, and family.So if two SAs have the same SPI but different destination addresses, thenthey will:a. Hash into different bucketsb. Be stored in different linked lists (byspi + h)c. Not be seen in the same hlist_for_each_entry_rcu() iteration.As a result, the lookup will result in NULL and kernel allows that Duplicate SPIProposed Change:xfrm_state_lookup_spi_proto() does a truly global search - across all states,regardless of hash bucket and matches SPI and proto.

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

Normally, we will set BNXT_TX_EVENT again when wesuccessfully call __bnxt_xmit_xdp(). But if the TX ring has no moreroom, the flag will not be set. This will cause the TX producer to beahead but the driver will not hit the TX doorbell.For multi-buf XDP_TX, there is no need to clear the event flags and setBNXT_AGG_EVENT. The BNXT_AGG_EVENT flag should have been set earlier inbnxt_rx_pkt().The visible symptom of this is that the RX ring associated with theTX XDP ring will eventually become empty and all packets will be dropped.Because this condition will cause the driver to not refill the RX ringseeing that the TX ring has forever pending XDP_TX packets.The fix is to only clear BNXT_RX_EVENT when we have successfullycalled __bnxt_xmit_xdp().

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-2025-38062 Severity: Moderate CVSS3 score: 5.8

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

CVE-2025-38084 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:mm/hugetlb: unshare page tables during VMA split, not beforeCurrently, __split_vma() triggers hugetlb page table unsharing throughvm_ops->may_split(). This happens before the VMA lock and rmap locks aretaken - which is too early, it allows racing VMA-locked page faults in ourprocess and racing rmap walks from other processes to cause page tables tobe shared again before we actually perform the split.Fix it by explicitly calling into the hugetlb unshare logic from__split_vma() in the same place where THP splitting also happens. At thatpoint, both the VMA and the rmap(s) are write-locked.An annoying detail is that we can now call into the helperhugetlb_unshare_pmds() from two different locking contexts:1. from hugetlb_split(), holding: - mmap lock (exclusively) - VMA lock - file rmap lock (exclusively)2. hugetlb_unshare_all_pmds(), which I think is designed to be able to call us with only the mmap lock held (in shared mode), but currently only runs while holding mmap lock (exclusively) and VMA lockBackporting note:This commit fixes a racy protection that was introduced in commitb30c14cd6102 ("hugetlb: unshare some PMDs when splitting VMAs"); thatcommit claimed to fix an issue introduced in 5.13, but it should actuallyalso go all the way back.[jannh@google.com: v2]

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

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.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Reject negative offsets for ALU opsWhen verifying BPF programs, the check_alu_op() function validatesinstructions with ALU operations. The 'offset' field in theseinstructions is a signed 16-bit integer.The existing check 'insn->off > 1' was intended to ensure the offset iseither 0, or 1 for BPF_MOD/BPF_DIV. However, because 'insn->off' issigned, this check incorrectly accepts all negative values (e.g., -1).This commit tightens the validation by changing the condition to'(insn->off != 0 && insn->off != 1)'. This ensures that any valueother than the explicitly permitted 0 and 1 is rejected, hardening theverifier against malformed BPF programs.

CVE-2025-61780 Severity: Moderate CVSS3 score: 5.8

Description: Rack is a modular Ruby web server interface. Prior to versions 2.2.20, 3.1.18, and 3.2.3, a possible information disclosure vulnerability existed in `Rack::Sendfile` when running behind a proxy that supports `x-sendfile` headers (such as Nginx). Specially crafted headers could cause `Rack::Sendfile` to miscommunicate with the proxy and trigger unintended internal requests, potentially bypassing proxy-level access restrictions. When `Rack::Sendfile` received untrusted `x-sendfile-type` or `x-accel-mapping` headers from a client, it would interpret them as proxy configuration directives. This could cause the middleware to send a "redirect" response to the proxy, prompting it to reissue a new internal request that was not subject to the proxy's access controls. An attacker could exploit this by setting a crafted `x-sendfile-type: x-accel-redirect` header, setting a crafted `x-accel-mapping` header, and requesting a path that qualifies for proxy-based acceleration. Attackers could bypass proxy-enforced restrictions and access internal endpoints intended to be protected (such as administrative pages). The vulnerability did not allow arbitrary file reads but could expose sensitive application routes. This issue only affected systems meeting all of the following conditions: The application used `Rack::Sendfile` with a proxy that supports `x-accel-redirect` (e.g., Nginx); the proxy did **not** always set or remove the `x-sendfile-type` and `x-accel-mapping` headers; and the application exposed an endpoint that returned a body responding to `.to_path`. Users should upgrade to Rack versions 2.2.20, 3.1.18, or 3.2.3, which require explicit configuration to enable `x-accel-redirect`. Alternatively, configure the proxy to always set or strip the header, or in Rails applications, disable sendfile completely.

Description: In the Linux kernel, the following vulnerability has been resolved:ksmbd: ipc: fix use-after-free in ipc_msg_send_requestipc_msg_send_request() waits for a generic netlink reply using anipc_msg_table_entry on the stack. The generic netlink handler(handle_generic_event()/handle_response()) fills entry->response underipc_msg_table_lock, but ipc_msg_send_request() used to validate and freeentry->response without holding the same lock.Under high concurrency this allows a race where handle_response() iscopying data into entry->response while ipc_msg_send_request() has justfreed it, leading to a slab-use-after-free reported by KASAN inhandle_generic_event(): BUG: KASAN: slab-use-after-free in handle_generic_event+0x3c4/0x5f0 [ksmbd] Write of size 12 at addr ffff888198ee6e20 by task pool/109349 ...

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

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

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

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

If the entry is dereferencedafter the RCU unlock, reading info could cause a Use-after-Free.A simple solution is to copy the required info while inside the RCUprotected section to avoid any risk of UaF later. The address ID mightneed to be modified later to handle the ID0 case later, so a copy seemsOK to deal with.

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.

We don't touch idx field for maximum performance, as it'schecked most frequently during backtracking.This change removes basically the last remaining practical limitation ofprecision backtracking logic in BPF verifier. It fixes knowndeficiencies, but also opens up new opportunities to reduce number ofverified states, explored in the subsequent patches.There are only three differences in selftests' BPF object filesaccording to veristat, all in the positive direction (less states).File Program Insns (A) Insns (B) Insns (DIFF) States (A) States (B) States (DIFF)-------------------------------------- ------------- --------- --------- ------------- ---------- ---------- -------------test_cls_redirect_dynptr.bpf.linked3.o cls_redirect 2987 2864 -123 (-4.12%) 240 231 -9 (-3.75%)xdp_synproxy_kern.bpf.linked3.o syncookie_tc 82848 82661 -187 (-0.23%) 5107 5073 -34 (-0.67%)xdp_synproxy_kern.bpf.linked3.o syncookie_xdp 85116 84964 -152 (-0.18%) 5162 5130 -32 (-0.62%)Note, I avoided renaming jmp_history to more generic insn_hist tominimize number of lines changed and potential merge conflicts betweenbpf and bpf-next trees.Notice also cur_hist_entry pointer reset to NULL at the beginning ofinstruction verification loop. This pointer avoids the problem ofrelying on last jump history entry's insn_idx to determine whether wealready have entry for current instruction or not. It can happen that weadded jump history entry because current instruction is_jmp_point(), butalso we need to add instruction flags for stack access. In this case, wedon't want to entries, so we need to reuse last added entry, if it ispresent.Relying on insn_idx comparison has the same ambiguity problem as the onethat was fixed recently in [0], so we avoid that.

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

CVE-2024-46733 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix qgroup reserve leaks in cow_file_rangeIn the buffered write path, the dirty page owns the qgroup reserve untilit creates an ordered_extent.Therefore, any errors that occur before the ordered_extent is createdmust free that reservation, or else the space is leaked. The fstestgeneric/475 exercises various IO error paths, and is able to triggererrors in cow_file_range where we fail to get to allocating the orderedextent. Note that because we *do* clear delalloc, we are likely toremove the inode from the delalloc list, so the inodes/pages to not haveinvalidate/launder called on them in the commit abort path.This results in failures at the unmount stage of the test that look like: BTRFS: error (device dm-8 state EA) in cleanup_transaction:2018: errno=-5 IO failure BTRFS: error (device dm-8 state EA) in btrfs_replace_file_extents:2416: errno=-5 IO failure BTRFS warning (device dm-8 state EA): qgroup 0/5 has unreleased space, type 0 rsv 28672 ------------[ cut here ]------------ WARNING: CPU: 3 PID: 22588 at fs/btrfs/disk-io.c:4333 close_ctree+0x222/0x4d0 [btrfs] Modules linked in: btrfs blake2b_generic libcrc32c xor zstd_compress raid6_pq CPU: 3 PID: 22588 Comm: umount Kdump: loaded Tainted: G W 6.10.0-rc7-gab56fde445b8 #21 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Arch Linux 1.16.3-1-1 04/01/2014 RIP: 0010:close_ctree+0x222/0x4d0 [btrfs] RSP: 0018:ffffb4465283be00 EFLAGS: 00010202 RAX: 0000000000000001 RBX: ffffa1a1818e1000 RCX: 0000000000000001 RDX: 0000000000000000 RSI: ffffb4465283bbe0 RDI: ffffa1a19374fcb8 RBP: ffffa1a1818e13c0 R08: 0000000100028b16 R09: 0000000000000000 R10: 0000000000000003 R11: 0000000000000003 R12: ffffa1a18ad7972c R13: 0000000000000000 R14: 0000000000000000 R15: 0000000000000000 FS: 00007f9168312b80(0000) GS:ffffa1a4afcc0000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f91683c9140 CR3: 000000010acaa000 CR4: 00000000000006f0 Call Trace: ? close_ctree+0x222/0x4d0 [btrfs] ? __warn.cold+0x8e/0xea ? close_ctree+0x222/0x4d0 [btrfs] ? report_bug+0xff/0x140 ? handle_bug+0x3b/0x70 ? exc_invalid_op+0x17/0x70 ? asm_exc_invalid_op+0x1a/0x20 ? close_ctree+0x222/0x4d0 [btrfs] generic_shutdown_super+0x70/0x160 kill_anon_super+0x11/0x40 btrfs_kill_super+0x11/0x20 [btrfs] deactivate_locked_super+0x2e/0xa0 cleanup_mnt+0xb5/0x150 task_work_run+0x57/0x80 syscall_exit_to_user_mode+0x121/0x130 do_syscall_64+0xab/0x1a0 entry_SYSCALL_64_after_hwframe+0x77/0x7f RIP: 0033:0x7f916847a887 ---[ end trace 0000000000000000 ]--- BTRFS error (device dm-8 state EA): qgroup reserved space leakedCases 2 and 3 in the out_reserve path both pertain to this type of leakand must free the reserved qgroup data.

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

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. Leading to thefollowint use-after-free KASAN warning:kernel: ==================================================================kernel: BUG: KASAN: slab-use-after-free in nfsd_breaker_owns_lease+0x140/0x160 [nfsd]kernel: Read of size 8 at addr ffff0000e73cd0c8 by task nfsd/6205kernel:kernel: CPU: 2 UID: 0 PID: 6205 Comm: nfsd Kdump: loaded Not tainted 6.11.0-rc7+ #9kernel: Hardware name: Apple Inc.

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

CVE-2024-57951 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:hrtimers: Handle CPU state correctly on hotplugConsider a scenario where a CPU transitions from CPUHP_ONLINE to halfwaythrough a CPU hotunplug down to CPUHP_HRTIMERS_PREPARE, and then back toCPUHP_ONLINE:Since hrtimers_prepare_cpu() does not run, cpu_base.hres_active remains setto 1 throughout. However, during a CPU unplug operation, the tick and theclockevents are shut down at CPUHP_AP_TICK_DYING. On return to the onlinestate, for instance CFS incorrectly assumes that the hrtick is alreadyactive, and the chance of the clockevent device to transition to oneshotmode is also lost forever for the CPU, unless it goes back to a lower statethan CPUHP_HRTIMERS_PREPARE once.This round-trip reveals another issue; cpu_base.online is not set to 1after the transition, which appears as a WARN_ON_ONCE in enqueue_hrtimer().Aside of that, the bulk of the per CPU state is not reset either, whichmeans there are dangling pointers in the worst case.Address this by adding a corresponding startup() callback, which resets thestale per CPU state and sets the online flag.[ tglx: Make the new callback unconditionally available, remove the online modification in the prepare() callback and clear the remaining state in the starting callback instead of the prepare callback ]

CVE-2024-57952 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:Revert "libfs: fix infinite directory reads for offset dir"The current directory offset allocator (based on mtree_alloc_cyclic)stores the next offset value to return in octx->next_offset. Thismechanism typically returns values that increase monotonically overtime. Eventually, though, the newly allocated offset value wrapsback to a low number (say, 2) which is smaller than other already-allocated offset values.Yu Kuai reports that, after commit 64a7ce76fb90("libfs: fix infinite directory reads for offset dir"), if adirectory's offset allocator wraps, existing entries are no longervisible via readdir/getdents because offset_readdir() stops listingentries once an entry's offset is larger than octx->next_offset.These entries vanish persistently -- they can be looked up, but willnever again appear in readdir(3) output.The reason for this is that the commit treats directory offsets asmonotonically increasing integer values rather than opaque cookies,and introduces this comparison: if (dentry2offset(dentry) >= last_index) {On 64-bit platforms, the directory offset value upper bound is2^63 - 1. Directory offsets will monotonically increase for millionsof years without wrapping.On 32-bit platforms, however, LONG_MAX is 2^31 - 1. The allocatorcan wrap after only a few weeks (at worst).Revert commit 64a7ce76fb90 ("libfs: fix infinite directory reads foroffset dir") to prepare for a fix that can work properly on 32-bitsystems and might apply to recent LTS kernels where shmem employsthe simple_offset mechanism.

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: x86: Acquire SRCU in KVM_GET_MP_STATE to protect guest memory accessesAcquire a lock on kvm->srcu when userspace is getting MP state to handle arather extreme edge case where "accepting" APIC events, i.e. processingpending INIT or SIPI, can trigger accesses to guest memory. If the vCPUis in L2 with INIT *and* a TRIPLE_FAULT request pending, then getting MPstate will trigger a nested VM-Exit by way of ->check_nested_events(), andemuating the nested VM-Exit can access guest memory.The splat was originally hit by syzkaller on a Google-internal kernel, andreproduced on an upstream kernel by hacking the triple_fault_event_testselftest to stuff a pending INIT, store an MSR on VM-Exit (to generate amemory access on VMX), and do vcpu_mp_state_get() to trigger the scenario. ============================= WARNING: suspicious RCU usage 6.14.0-rc3-b112d356288b-vmx/pi_lockdep_false_pos-lock #3 Not tainted ----------------------------- include/linux/kvm_host.h:1058 suspicious rcu_dereference_check() usage! other info that might help us debug this: rcu_scheduler_active = 2, debug_locks = 1 1 lock held by triple_fault_ev/1256: #0: ffff88810df5a330 (&vcpu->mutex){+.+.}-{4:4}, at: kvm_vcpu_ioctl+0x8b/0x9a0 [kvm] stack backtrace: CPU: 11 UID: 1000 PID: 1256 Comm: triple_fault_ev Not tainted 6.14.0-rc3-b112d356288b-vmx #3 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 Call Trace: dump_stack_lvl+0x7f/0x90 lockdep_rcu_suspicious+0x144/0x190 kvm_vcpu_gfn_to_memslot+0x156/0x180 [kvm] kvm_vcpu_read_guest+0x3e/0x90 [kvm] read_and_check_msr_entry+0x2e/0x180 [kvm_intel] __nested_vmx_vmexit+0x550/0xde0 [kvm_intel] kvm_check_nested_events+0x1b/0x30 [kvm] kvm_apic_accept_events+0x33/0x100 [kvm] kvm_arch_vcpu_ioctl_get_mpstate+0x30/0x1d0 [kvm] kvm_vcpu_ioctl+0x33e/0x9a0 [kvm] __x64_sys_ioctl+0x8b/0xb0 do_syscall_64+0x6c/0x170 entry_SYSCALL_64_after_hwframe+0x4b/0x53

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

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

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

CVE-2025-38124 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix udp gso skb_segment after pull from frag_listCommit a1e40ac5b5e9 ("net: gso: fix udp gso fraglist segmentation afterpull from frag_list") detected invalid geometry in frag_list skbs andredirects them from skb_segment_list to more robust skb_segment. But somepackets with modified geometry can also hit bugs in that code. We don'tknow how many such cases exist. Addressing each one by one also requirestouching the complex skb_segment code, which risks introducing bugs forother types of skbs. Instead, linearize all these packets that fail thebasic invariants on gso fraglist skbs. That is more robust.If only part of the fraglist payload is pulled into head_skb, it willalways cause exception when splitting skbs by skb_segment. For detailedcall stack information, see below.Valid SKB_GSO_FRAGLIST skbs- consist of two or more segments- the head_skb holds the protocol headers plus first gso_size- one or more frag_list skbs hold exactly one segment- all but the last must be gso_sizeOptional datapath hooks such as NAT and BPF (bpf_skb_pull_data) canmodify fraglist skbs, breaking these invariants.In extreme cases they pull one part of data into skb linear. For UDP,this causes three payloads with lengths of (11,11,10) bytes werepulled tail to become (12,10,10) bytes.The skbs no longer meets the above SKB_GSO_FRAGLIST conditions becausepayload was pulled into head_skb, it needs to be linearized before passto regular skb_segment. skb_segment+0xcd0/0xd14 __udp_gso_segment+0x334/0x5f4 udp4_ufo_fragment+0x118/0x15c inet_gso_segment+0x164/0x338 skb_mac_gso_segment+0xc4/0x13c __skb_gso_segment+0xc4/0x124 validate_xmit_skb+0x9c/0x2c0 validate_xmit_skb_list+0x4c/0x80 sch_direct_xmit+0x70/0x404 __dev_queue_xmit+0x64c/0xe5c neigh_resolve_output+0x178/0x1c4 ip_finish_output2+0x37c/0x47c __ip_finish_output+0x194/0x240 ip_finish_output+0x20/0xf4 ip_output+0x100/0x1a0 NF_HOOK+0xc4/0x16c ip_forward+0x314/0x32c ip_rcv+0x90/0x118 __netif_receive_skb+0x74/0x124 process_backlog+0xe8/0x1a4 __napi_poll+0x5c/0x1f8 net_rx_action+0x154/0x314 handle_softirqs+0x154/0x4b8 [118.376811] [C201134] rxq0_pus: [name:bug&]kernel BUG at net/core/skbuff.c:4278!

Description: In the Linux kernel, the following vulnerability has been resolved:usb: renesas_usbhs: Reorder clock handling and power management in probeReorder the initialization sequence in `usbhs_probe()` to enable runtimePM before accessing registers, preventing potential crashes due touninitialized clocks.Currently, in the probe path, registers are accessed before enabling theclocks, leading to a synchronous external abort on the RZ/V2H SoC.The problematic call flow is as follows: usbhs_probe() usbhs_sys_clock_ctrl() usbhs_bset() usbhs_write() iowrite16() <-- Register access before enabling clocksSince `iowrite16()` is performed without ensuring the required clocks areenabled, this can lead to access errors.

A previous commit(see Fixes tag) introduced skb_get()to avoid race conditions between skb operations in the backlog and skbrelease in the recvmsg path. However, this caused the panic to alwaysoccur when skb_linearize is executed.The "--rx-strp 100000" parameter forces the RX path to use the strparsermodule which aggregates data until it reaches 100KB before calling sockmaplogic. The 100KB payload exceeds MAX_MSG_FRAGS, triggering skb_linearize.To fix this issue, just move skb_get into sk_psock_skb_ingress_enqueue.'''sk_psock_backlog: sk_psock_handle_skb skb_get(skb) <== we move it into 'sk_psock_skb_ingress_enqueue' sk_psock_skb_ingress____________ v | | -> sk_psock_skb_ingress_self | sk_psock_skb_ingress_enqueuesk_psock_verdict_apply_________________^ skb_linearize'''Note that for verdict_apply path, the skb_get operation is unnecessary sowe add 'take_ref' param to control it's behavior.

Description: In the Linux kernel, the following vulnerability has been resolved:net: dsa: b53: do not enable EEE on bcm63xxBCM63xx internal switches do not support EEE, but provide multiple RGMIIports where external PHYs may be connected. If one of these PHYs are EEEcapable, we may try to enable EEE for the MACs, which then hangs thesystem on access of the (non-existent) EEE registers.Fix this by checking if the switch actually supports EEE beforeattempting to configure it.

CVE-2025-38275 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:phy: qcom-qmp-usb: Fix an NULL vs IS_ERR() bugThe qmp_usb_iomap() helper function currently returns the raw result ofdevm_ioremap() for non-exclusive mappings. Since devm_ioremap() may returna NULL pointer and the caller only checks error pointers with IS_ERR(),NULL could bypass the check and lead to an invalid dereference.Fix the issue by checking if devm_ioremap() returns NULL. When it does,qmp_usb_iomap() now returns an error pointer via IOMEM_ERR_PTR(-ENOMEM),ensuring safe and consistent error handling.

Active traffic on the leaf node must be stopped before its send queue is reassigned to the parent. This patch resolves the issue by marking the node as 'Inner'.2. During a system reboot, the interface receives TC_HTB_LEAF_DEL and TC_HTB_LEAF_DEL_LAST callbacks to delete its HTB queues. In the case of TC_HTB_LEAF_DEL_LAST, although the same send queue is reassigned to the parent, the current logic still attempts to update the real number of queues, leadning to below warnings New queues can't be registered after device unregistration.

And in the function that uses ptp->n_vclocks, wealready get ptp->n_vclocks_mux before unregistering vclocks.Therefore, we need to remove the redundant check for ptp->n_vclocks inptp_vclock_in_use() to prevent recursive locking.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: lpfc: Use memcpy() for BIOS versionThe strlcat() with FORTIFY support is triggering a panic because itthinks the target buffer will overflow although the correct targetbuffer size is passed in.Anyway, instead of memset() with 0 followed by a strlcat(), just usememcpy() and ensure that the resulting buffer is NULL terminated.BIOSVersion is only used for the lpfc_printf_log() which expects aproperly terminated string.

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: x86/hyper-v: Skip non-canonical addresses during PV TLB flushIn KVM guests with Hyper-V hypercalls enabled, the hypercallsHVCALL_FLUSH_VIRTUAL_ADDRESS_LIST and HVCALL_FLUSH_VIRTUAL_ADDRESS_LIST_EXallow a guest to request invalidation of portions of a virtual TLB.For this, the hypercall parameter includes a list of GVAs that are supposedto be invalidated.However, when non-canonical GVAs are passed, there is currently nofiltering in place and they are eventually passed to checked invocations ofINVVPID on Intel / INVLPGA on AMD. While AMD's INVLPGA silently ignoresnon-canonical addresses (effectively a no-op), Intel's INVVPID explicitlysignals VM-Fail and ultimately triggers the WARN_ONCE in invvpid_error(): invvpid failed: ext=0x0 vpid=1 gva=0xaaaaaaaaaaaaa000 WARNING: CPU: 6 PID: 326 at arch/x86/kvm/vmx/vmx.c:482 invvpid_error+0x91/0xa0 [kvm_intel] Modules linked in: kvm_intel kvm 9pnet_virtio irqbypass fuse CPU: 6 UID: 0 PID: 326 Comm: kvm-vm Not tainted 6.15.0 #14 PREEMPT(voluntary) RIP: 0010:invvpid_error+0x91/0xa0 [kvm_intel] Call Trace: vmx_flush_tlb_gva+0x320/0x490 [kvm_intel] kvm_hv_vcpu_flush_tlb+0x24f/0x4f0 [kvm] kvm_arch_vcpu_ioctl_run+0x3013/0x5810 [kvm]Hyper-V documents that invalid GVAs (those that are beyond a partition'sGVA space) are to be ignored. While not completely clear whether thisruling also applies to non-canonical GVAs, it is likely fine to make thatassumption, and manual testing on Azure confirms "real" Hyper-V interpretsthe specification in the same way.Skip non-canonical GVAs when processing the list of address to avoidtripping the INVVPID failure. Alternatively, KVM could filter out "bad"GVAs before inserting into the FIFO, but practically speaking the onlydownside of pushing validation to the final processing is that doing sois suboptimal for the guest, and no well-behaved guest will request TLBflushes for non-canonical addresses.

CVE-2025-38376 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:usb: chipidea: udc: disconnect/reconnect from host when do suspend/resumeShawn and John reported a hang issue during system suspend as below: - USB gadget is enabled as Ethernet - There is data transfer over USB Ethernet (scp a big file between host and device) - Device is going in/out suspend (echo mem > /sys/power/state)The root cause is the USB device controller is suspended but the USB busis still active which caused the USB host continues to transfer data withdevice and the device continues to queue USB requests (in this case, adelayed TCP ACK packet trigger the issue) after controller is suspended,however the USB controller clock is already gated off. Then if udc driveraccess registers after that point, the system will hang.The correct way to avoid such issue is to disconnect device from host whenthe USB bus is not at suspend state. Then the host will receive disconnectevent and stop data transfer in time. To continue make USB gadget devicework after system resume, this will reconnect device automatically.To make usb wakeup work if USB bus is already at suspend state, this willkeep connection for it only when USB device controller has enabled wakeupcapability.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:firmware: arm_ffa: Fix memory leak by freeing notifier callback nodeCommit e0573444edbf ("firmware: arm_ffa: Add interfaces to requestnotification callbacks") adds support for notifier callbacks by allocatingand inserting a callback node into a hashtable during registration ofnotifiers. However, during unregistration, the code only removes thenode from the hashtable without freeing the associated memory, resultingin a memory leak.Resolve the memory leak issue by ensuring the allocated notifier callbacknode is properly freed after it is removed from the hashtable entry.

Description: In the Linux kernel, the following vulnerability has been resolved:perf: Fix sample vs do_exit()Baisheng Gao reported an ARM64 crash, which Mark decoded as being asynchronous external abort -- most likely due to trying to accessMMIO in bad ways.The crash further shows perf trying to do a user stack sample while inexit_mmap()'s tlb_finish_mmu() -- i.e. while tearing down the addressspace it is trying to access.It turns out that we stop perf after we tear down the userspace mm; areceipie for disaster, since perf likes to access userspace forvarious reasons.Flip this order by moving up where we stop perf in do_exit().Additionally, harden PERF_SAMPLE_CALLCHAIN and PERF_SAMPLE_STACK_USERto abort when the current task does not have an mm (exit_mm() makessure to set current->mm = NULL; before commencing with the actualteardown). Such that CPU wide events don't trip on this same problem.

CVE-2025-38427 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:video: screen_info: Relocate framebuffers behind PCI bridgesApply PCI host-bridge window offsets to screen_info framebuffers. Fixesinvalid access to I/O memory.Resources behind a PCI host bridge can be relocated by a certain offsetin the kernel's CPU address range used for I/O. The framebuffer memoryrange stored in screen_info refers to the CPU addresses as seen duringboot (where the offset is 0). During boot up, firmware may assign adifferent memory offset to the PCI host bridge and thereby relocatingthe framebuffer address of the PCI graphics device as seen by the kernel.The information in screen_info must be updated as well.The helper pcibios_bus_to_resource() performs the relocation of thescreen_info's framebuffer resource (given in PCI bus addresses). Theresult matches the I/O-memory resource of the PCI graphics device (givenin CPU addresses). As before, we store away the information necessary tolater update the information in screen_info itself.Commit 78aa89d1dfba ("firmware/sysfb: Update screen_info for relocatedEFI framebuffers") added the code for updating screen_info. It is basedon similar functionality that pre-existed in efifb. Efifb uses a pointerto the PCI resource, while the newer code does a memcpy of the region.Hence efifb sees any updates to the PCI resource and avoids the issue.v3:- Only use struct pci_bus_region for PCI bus addresses (Bjorn)- Clarify address semantics in commit messages and comments (Bjorn)v2:- Fixed tags (Takashi, Ivan)- Updated information on efifb

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

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

Because of this, netem_dequeue calls qdisc_tree_reduce_backlog, and since qlen is now 0, it calls htb_qlen_notify -> htb_deactivate -> htb_deactiviate_prios -> htb_remove_class_from_row -> htb_safe_rb_erase5. As this is the only class in the selected hprio rbtree, __rb_change_child in __rb_erase_augmented sets the rb_root pointer to NULL6. Because blackhole_dequeue returns NULL, netem_dequeue returns NULL, which causes htb_dequeue_tree to call htb_lookup_leaf with the same hprio rbtree, and fail the BUG_ONThe function graph for this scenario is shown here: 0) | htb_enqueue() { 0) + 13.635 us | netem_enqueue(); 0) 4.719 us | htb_activate_prios(); 0) # 2249.199 us | } 0) | htb_dequeue() { 0) 2.355 us | htb_lookup_leaf(); 0) | netem_dequeue() { 0) + 11.061 us | blackhole_enqueue(); 0) | qdisc_tree_reduce_backlog() { 0) | qdisc_lookup_rcu() { 0) 1.873 us | qdisc_match_from_root(); 0) 6.292 us | } 0) 1.894 us | htb_search(); 0) | htb_qlen_notify() { 0) 2.655 us | htb_deactivate_prios(); 0) 6.933 us | } 0) + 25.227 us | } 0) 1.983 us | blackhole_dequeue(); 0) + 86.553 us | } 0) # 2932.761 us | qdisc_warn_nonwc(); 0) | htb_lookup_leaf() { 0) | BUG_ON(); ------------------------------------------The full original bug report can be seen here [1].We can fix this just by returning NULL instead of the BUG_ON,as htb_dequeue_tree returns NULL when htb_lookup_leaf returnsNULL.[1] https://lore.kernel.org/netdev/pF5XOOIim0IuEfhI-SOxTgRvNoDwuux7UHKnE_Y5-zVd4wmGvNk2ceHjKb8ORnzw0cGwfmVu42g9dL7XyJLf1NEzaztboTWcm0Ogxuojoeo=@willsroot.io/

CVE-2025-38470 Severity: Moderate CVSS3 score: 5.5

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: Fix recv-recv race of completed callIf a call receives an event (such as incoming data), the call gets placedon the socket's queue and a thread in recvmsg can be awakened to go andprocess it. Once the thread has picked up the call off of the queue,further events will cause it to be requeued, and once the socket lock isdropped (recvmsg uses call->user_mutex to allow the socket to be used inparallel), a second thread can come in and its recvmsg can pop the call offthe socket queue again.In such a case, the first thread will be receiving stuff from the call andthe second thread will be blocked on call->user_mutex. The first threadcan, at this point, process both the event that it picked call for and theevent that the second thread picked the call for and may see the callterminate - in which case the call will be "released", decoupling the callfrom the user call ID assigned to it (RXRPC_USER_CALL_ID in the controlmessage).The first thread will return okay, but then the second thread will wake upholding the user_mutex and, if it sees that the call has been released bythe first thread, it will BUG thusly: kernel BUG at net/rxrpc/recvmsg.c:474!Fix this by just dequeuing the call and ignoring it if it is seen to bealready released.

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: Restrict conditions for adding duplicating netems to qdisc treenetem_enqueue's duplication prevention logic breaks when a netemresides in a qdisc tree with other netems - this can lead to asoft lockup and OOM loop in netem_dequeue, as seen in [1].Ensure that a duplicating netem cannot exist in a tree with othernetems.Previous approaches suggested in discussions in chronological order:1) Track duplication status or ttl in the sk_buff struct. Consideredtoo specific a use case to extend such a struct, though this wouldbe a resilient fix and address other previous and potential futureDOS bugs like the one described in loopy fun [2].2) Restrict netem_enqueue recursion depth like in act_mirred with aper cpu variable. However, netem_dequeue can call enqueue on itschild, and the depth restriction could be bypassed if the child is anetem.3) Use the same approach as in 2, but add metadata in netem_skb_cbto handle the netem_dequeue case and track a packet's involvementin duplication. This is an overly complex approach, and Jamalnotes that the skb cb can be overwritten to circumvent thissafeguard.4) Prevent the addition of a netem to a qdisc tree if its ancestralpath contains a netem. However, filters and actions can cause apacket to change paths when re-enqueued to the root from netemduplication, leading us to the current solution: prevent aduplicating netem from inhabiting the same tree as other netems.[1] https://lore.kernel.org/netdev/8DuRWwfqjoRDLDmBMlIfbrsZg9Gx50DHJc1ilxsEBNe2D6NMoigR_eIRIG0LOjMc3r10nUUZtArXx4oZBIdUfZQrwjcQhdinnMis_0G7VEk=@willsroot.io/[2] https://lwn.net/Articles/719297/

Description: In the Linux kernel, the following vulnerability has been resolved:HID: apple: validate feature-report field count to prevent NULL pointer dereferenceA malicious HID device with quirk APPLE_MAGIC_BACKLIGHT can trigger a NULLpointer dereference whilst the power feature-report is toggled and sent tothe device in apple_magic_backlight_report_set(). The power feature-reportis expected to have two data fields, but if the descriptor declares onefield then accessing field[1] and dereferencing it inapple_magic_backlight_report_set() becomes invalidsince field[1] will be NULL.An example of a minimal descriptor which can cause the crash is somethinglike the following where the report with ID 3 (power report) onlyreferences a single 1-byte field.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf, arm64: Fix fp initialization for exception boundaryIn the ARM64 BPF JIT when prog->aux->exception_boundary is set for a BPFprogram, find_used_callee_regs() is not called because for a programacting as exception boundary, all callee saved registers are saved.find_used_callee_regs() sets `ctx->fp_used = true;` when it sees FPbeing used in any of the instructions.For programs acting as exception boundary, ctx->fp_used remains falseeven if frame pointer is used by the program and therefore, FP is notset-up for such programs in the prologue. This can cause the kernel tocrash due to a pagefault.Fix it by setting ctx->fp_used = true for exception boundary programs asfp is always saved in such programs.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:powercap: dtpm_cpu: Fix NULL pointer dereference in get_pd_power_uw()The get_pd_power_uw() function can crash with a NULL pointer dereferencewhen em_cpu_get() returns NULL. This occurs when a CPU becomes impossibleduring runtime, causing get_cpu_device() to return NULL, which propagatesthrough em_cpu_get() and leads to a crash when em_span_cpus() dereferencesthe NULL pointer.Add a NULL check after em_cpu_get() and return 0 if unavailable,matching the existing fallback behavior in __dtpm_cpu_setup().[ rjw: Drop an excess empty code line ]

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: pnv_php: Clean up allocated IRQs on unplugWhen the root of a nested PCIe bridge configuration is unplugged, thepnv_php driver leaked the allocated IRQ resources for the child bridges'hotplug event notifications, resulting in a panic.Fix this by walking all child buses and deallocating all its IRQ resourcesbefore calling pci_hp_remove_devices().Also modify the lifetime of the workqueue at struct pnv_php_slot::wq sothat it is only destroyed in pnv_php_free_slot(), instead ofpnv_php_disable_irq(). This is required since pnv_php_disable_irq() willnow be called by workers triggered by hot unplug interrupts, so theworkqueue needs to stay allocated.The abridged kernel panic that occurs without this patch is as follows: WARNING: CPU: 0 PID: 687 at kernel/irq/msi.c:292 msi_device_data_release+0x6c/0x9c CPU: 0 UID: 0 PID: 687 Comm: bash Not tainted 6.14.0-rc5+ #2 Call Trace: msi_device_data_release+0x34/0x9c (unreliable) release_nodes+0x64/0x13c devres_release_all+0xc0/0x140 device_del+0x2d4/0x46c pci_destroy_dev+0x5c/0x194 pci_hp_remove_devices+0x90/0x128 pci_hp_remove_devices+0x44/0x128 pnv_php_disable_slot+0x54/0xd4 power_write_file+0xf8/0x18c pci_slot_attr_store+0x40/0x5c sysfs_kf_write+0x64/0x78 kernfs_fop_write_iter+0x1b0/0x290 vfs_write+0x3bc/0x50c ksys_write+0x84/0x140 system_call_exception+0x124/0x230 system_call_vectored_common+0x15c/0x2ec[bhelgaas: tidy comments]

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:i2c: qup: jump out of the loop in case of timeoutOriginal logic only sets the return value but doesn't jump out of theloop if the bus is kept active by a client. This is not expected. Amalicious or buggy i2c client can hang the kernel in this case andshould be avoided. This is observed during a long time test with aPCA953x GPIO extender.Fix it by changing the logic to not only sets the return value, but alsojumps out of the loop and return to the caller with -ETIMEDOUT.

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

CVE-2025-38679 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:media: venus: Fix OOB read due to missing payload bound checkCurrently, The event_seq_changed() handler processes a variable numberof properties sent by the firmware. The number of properties is indicatedby the firmware and used to iterate over the payload. However, thepayload size is not being validated against the actual message length.This can lead to out-of-bounds memory access if the firmware provides aproperty count that exceeds the data available in the payload. Such acondition can result in kernel crashes or potential information leaks ifmemory beyond the buffer is accessed.Fix this by properly validating the remaining size of the payload beforeeach property access and updating bounds accordingly as properties areparsed.This ensures that property parsing is safely bounded within the receivedmessage buffer and protects against malformed or malicious firmwarebehavior.

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

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

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

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

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

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

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

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

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

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

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

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

Therefore,if the application closes the socket immediately after accept,newclcsock->sk can be NULL. A possible execution order could be asfollows:smc_listen_work | userspace-----------------------------------------------------------------lock_sock(sk) |smc_listen_out_connected() || \- smc_listen_out || | \- release_sock | | |- sk->sk_data_ready() | | fd = accept(); | close(fd); | \- socket->sk = NULL;/* newclcsock->sk is NULL now */SMC_STAT_SERV_SUCC_INC(sock_net(newclcsock->sk))Since smc_listen_out_connected() will not fail, simply swapping the orderof the code can easily fix this issue.

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

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: pcl726: Prevent invalid irq numberThe reproducer passed in an irq number(0x80008000) that was too large,which triggered the oob.Added an interrupt number check to prevent users from passing in an irqnumber that was too large.If `it->options[1]` is 31, then `1 << it->options[1]` is still invalidbecause it shifts a 1-bit into the sign bit (which is UB in C).Possible solutions include reducing the upper bound on the`it->options[1]` value to 30 or lower, or using `1U << it->options[1]`.The old code would just not attempt to request the IRQ if the`options[1]` value were invalid. And it would still configure thedevice without interrupts even if the call to `request_irq` returned anerror. So it would be better to combine this test with the test below.

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:ftrace: Also allocate and copy hash for reading of filter filesCurrently the reader of set_ftrace_filter and set_ftrace_notrace just addsthe pointer to the global tracer hash to its iterator. Unlike the writerthat allocates a copy of the hash, the reader keeps the pointer to thefilter hashes. This is problematic because this pointer is static acrossfunction calls that release the locks that can update the global tracerhashes. This can cause UAF and similar bugs.Allocate and copy the hash for reading the filter files like it is donefor the writers. This not only fixes UAF bugs, but also makes the code abit simpler as it doesn't have to differentiate when to free theiterator's hash between writers and readers.

Description: In the Linux kernel, the following vulnerability has been resolved:s390/sclp: Fix SCCB present checkTracing code called by the SCLP interrupt handler contains early exitsif the SCCB address associated with an interrupt is NULL. This check isperformed after physical to virtual address translation.If the kernel identity mapping does not start at address zero, theresulting virtual address is never zero, so that the NULL checks won'twork. Subsequently this may result in incorrect accesses to the firstpage of the identity mapping.Fix this by introducing a function that handles the NULL case beforeaddress translation.

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

Description: In the Linux kernel, the following vulnerability has been resolved:iio: imu: bno055: fix OOB access of hw_xlate arrayFix a potential out-of-bounds array access of the hw_xlate array inbno055.c.In bno055_get_regmask(), hw_xlate was iterated over the length of thevals array instead of the length of the hw_xlate array. In the case ofbno055_gyr_scale, the vals array is larger than the hw_xlate array,so this could result in an out-of-bounds access. In practice, thisshouldn't happen though because a match should always be found whichbreaks out of the for loop before it iterates beyond the end of thehw_xlate array.By adding a new hw_xlate_len field to the bno055_sysfs_attr, we can besure we are iterating over the correct length.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:netfs: Fix unbuffered write error handlingIf all the subrequests in an unbuffered write stream fail, the subrequestcollector doesn't update the stream->transferred value and it retains itsinitial LONG_MAX value. Unfortunately, if all active streams fail, then wetake the smallest value of { LONG_MAX, LONG_MAX, ... } as the value to setin wreq->transferred - which is then returned from ->write_iter().LONG_MAX was chosen as the initial value so that all the streams can bequickly assessed by taking the smallest value of all stream->transferred -but this only works if we've set any of them.Fix this by adding a flag to indicate whether the value instream->transferred is valid and checking that when we integrate thevalues. stream->transferred can then be initialised to zero.This was found by running the generic/750 xfstest against cifs withcache=none. It splices data to the target file. Once (if) it has used upall the available scratch space, the writes start failing with ENOSPC.This causes ->write_iter() to fail. However, it was returningwreq->transferred, i.e. LONG_MAX, rather than an error (because it thoughtthe amount transferred was non-zero) and iter_file_splice_write() wouldthen try to clean up that amount of pipe bufferage - leading to an oopswhen it overran.

CVE-2025-39726 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:s390/ism: fix concurrency management in ism_cmd()The s390x ISM device data sheet clearly states that only onerequest-response sequence is allowable per ISM function at any point intime. Unfortunately as of today the s390/ism driver in Linux does nothonor that requirement. This patch aims to rectify that.This problem was discovered based on Aliaksei's bug report which statesthat for certain workloads the ISM functions end up entering error state(with PEC 2 as seen from the logs) after a while and as a consequenceconnections handled by the respective function break, and for futureconnection requests the ISM device is not considered -- given it is in adysfunctional state. During further debugging PEC 3A was observed aswell.A kernel message like[ 1211.244319] zpci: 061a:00:00.0: Event 0x2 reports an error for PCI function 0x61ais a reliable indicator of the stated function entering error statewith PEC 2. Let me also point out that a kernel message like[ 1211.244325] zpci: 061a:00:00.0: The ism driver bound to the device does not support error recoveryis a reliable indicator that the ISM function won't be auto-recoveredbecause the ISM driver currently lacks support for it.On a technical level, without this synchronization, commands (inputs tothe FW) may be partially or fully overwritten (corrupted) by another CPUtrying to issue commands on the same function. There is hard evidence thatthis can lead to DMB token values being used as DMB IOVAs, leading toPEC 2 PCI events indicating invalid DMA. But this is only one of thefailure modes imaginable. In theory even completely losing one commandand executing another one twice and then trying to interpret the outputsas if the command we intended to execute was actually executed and notthe other one is also possible. Frankly, I don't feel confident aboutproviding an exhaustive list of possible consequences.

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

In the strictKCSAN mode of operation used by RCU, this constitutes a data race onthe ->defer_qs_iw_pending field.This commit therefore disables interrupts across the portion of thercu_preempt_deferred_qs_handler() that updates the ->defer_qs_iw_pendingfield. This suffices because this handler is not a fast path.

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

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/siw: Fix the sendmsg byte count in siw_tcp_sendpagesEver since commit c2ff29e99a76 ("siw: Inline do_tcp_sendpages()"),we have been doing this:static int siw_tcp_sendpages(struct socket *s, struct page **page, int offset, size_t size)[...] /* Calculate the number of bytes we need to push, for this page * specifically */ size_t bytes = min_t(size_t, PAGE_SIZE - offset, size); /* If we can't splice it, then copy it in, as normal */ if (!sendpage_ok(page[i])) msg.msg_flags &= ~MSG_SPLICE_PAGES; /* Set the bvec pointing to the page, with len $bytes */ bvec_set_page(&bvec, page[i], bytes, offset); /* Set the iter to $size, aka the size of the whole sendpages (!!!) */ iov_iter_bvec(&msg.msg_iter, ITER_SOURCE, &bvec, 1, size);try_page_again: lock_sock(sk); /* Sendmsg with $size size (!!!) */ rv = tcp_sendmsg_locked(sk, &msg, size);This means we've been sending oversized iov_iters and tcp_sendmsg callsfor a while. This has a been a benign bug because sendpage_ok() alwaysreturned true. With the recent slab allocator changes being slowlyintroduced into next (that disallow sendpage on large kmallocallocations), we have recently hit out-of-bounds crashes, due to slightdifferences in iov_iter behavior between the MSG_SPLICE_PAGES and"regular" copy paths:(MSG_SPLICE_PAGES)skb_splice_from_iter iov_iter_extract_pages iov_iter_extract_bvec_pages uses i->nr_segs to correctly stop in its tracks before OoB'ing everywhere skb_splice_from_iter gets a "short" read(!MSG_SPLICE_PAGES)skb_copy_to_page_nocache copy=iov_iter_count [...] copy_from_iter /* this doesn't help */ if (unlikely(iter->count < len)) len = iter->count; iterate_bvec ... and we run off the bvecsFix this by properly setting the iov_iter's byte count, plus sending thecorrect byte count to tcp_sendmsg_locked.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: ctnetlink: remove refcounting in expectation dumpersSame pattern as previous patch: do not keep the expectation objectalive via refcount, only store a cookie value and then use thatas the skip hint for dump resumption.AFAICS this has the same issue as the one resolved in the conntrackdumper, when we do if (!refcount_inc_not_zero(&exp->use))to increment the refcount, there is a chance that exp == last, whichcauses a double-increment of the refcount and subsequent memory leak.

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

Itwill call the count_max_entries() to find in an out-of-order date whichcounting algorithm has O(n^2) complexity.To make it faster, we sort the relocation list by info and addend. Thatway, to check for a duplicate relocation, it just needs to compare withthe previous entry. This reduces the complexity of the algorithm to O(n log n), as done in commit d4e0340919fb ("arm64/module: Optimize moduleload time by optimizing PLT counting"). This gives sinificant reductionin module load time for modules with large number of relocations.After applying this patch, the soft deadlock problem has been solved,and the kernel starts normally without "Call Trace".Using the default configuration to test some modules, the results are asfollows:Module Sizeip_tables 36Kfat 143Kradeon 2.5MBamdgpu 16MBWithout this patch:Module Module load time (ms) Count(PLTs/GOTs)ip_tables 18 59/6fat 0 162/14radeon 54 1221/84amdgpu 1411 4525/1098With this patch:Module Module load time (ms) Count(PLTs/GOTs)ip_tables 18 59/6fat 0 162/14radeon 22 1221/84amdgpu 45 4525/1098

CVE-2025-39770 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: gso: Forbid IPv6 TSO with extensions on devices with only IPV6_CSUMWhen performing Generic Segmentation Offload (GSO) on an IPv6 packet thatcontains extension headers, the kernel incorrectly requests checksum offloadif the egress device only advertises NETIF_F_IPV6_CSUM feature, which hasa strict contract: it supports checksum offload only for plain TCP or UDPover IPv6 and explicitly does not support packets with extension headers.The current GSO logic violates this contract by failing to disable the featurefor packets with extension headers, such as those used in GREoIPv6 tunnels.This violation results in the device being asked to perform an operationit cannot support, leading to a `skb_warn_bad_offload` warning and a collapseof network throughput. While device TSO/USO is correctly bypassed in favorof software GSO for these packets, the GSO stack must be explicitly told notto request checksum offload.Mask NETIF_F_IPV6_CSUM, NETIF_F_TSO6 and NETIF_F_GSO_UDP_L4in gso_features_check if the IPv6 header contains extension headers to computechecksum in software.The exception is a BIG TCP extension, which, as stated in commit68e068cabd2c6c53 ("net: reenable NETIF_F_IPV6_CSUM offload for BIG TCP packets"):"The feature is only enabled on devices that support BIG TCP TSO.The header is only present for PF_PACKET taps like tcpdump,and not transmitted by physical devices."kernel log output (truncated):WARNING: CPU: 1 PID: 5273 at net/core/dev.c:3535 skb_warn_bad_offload+0x81/0x140...Call Trace: skb_checksum_help+0x12a/0x1f0 validate_xmit_skb+0x1a3/0x2d0 validate_xmit_skb_list+0x4f/0x80 sch_direct_xmit+0x1a2/0x380 __dev_xmit_skb+0x242/0x670 __dev_queue_xmit+0x3fc/0x7f0 ip6_finish_output2+0x25e/0x5d0 ip6_finish_output+0x1fc/0x3f0 ip6_tnl_xmit+0x608/0xc00 [ip6_tunnel] ip6gre_tunnel_xmit+0x1c0/0x390 [ip6_gre] dev_hard_start_xmit+0x63/0x1c0 __dev_queue_xmit+0x6d0/0x7f0 ip6_finish_output2+0x214/0x5d0 ip6_finish_output+0x1fc/0x3f0 ip6_xmit+0x2ca/0x6f0 ip6_finish_output+0x1fc/0x3f0 ip6_xmit+0x2ca/0x6f0 inet6_csk_xmit+0xeb/0x150 __tcp_transmit_skb+0x555/0xa80 tcp_write_xmit+0x32a/0xe90 tcp_sendmsg_locked+0x437/0x1110 tcp_sendmsg+0x2f/0x50...skb linear: 00000000: e4 3d 1a 7d ec 30 e4 3d 1a 7e 5d 90 86 dd 60 0eskb linear: 00000010: 00 0a 1b 34 3c 40 20 11 00 00 00 00 00 00 00 00skb linear: 00000020: 00 00 00 00 00 12 20 11 00 00 00 00 00 00 00 00skb linear: 00000030: 00 00 00 00 00 11 2f 00 04 01 04 01 01 00 00 00skb linear: 00000040: 86 dd 60 0e 00 0a 1b 00 06 40 20 23 00 00 00 00skb linear: 00000050: 00 00 00 00 00 00 00 00 00 12 20 23 00 00 00 00skb linear: 00000060: 00 00 00 00 00 00 00 00 00 11 bf 96 14 51 13 f9skb linear: 00000070: ae 27 a0 a8 2b e3 80 18 00 40 5b 6f 00 00 01 01skb linear: 00000080: 08 0a 42 d4 50 d5 4b 70 f8 1a

CVE-2025-39776 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm/debug_vm_pgtable: clear page table entries at destroy_args()The mm/debug_vm_pagetable test allocates manually page table entries forthe tests it runs, using also its manually allocated mm_struct. That initself is ok, but when it exits, at destroy_args() it fails to clear thoseentries with the *_clear functions.The problem is that leaves stale entries. If another process allocates anmm_struct with a pgd at the same address, it may end up running into thestale entry.

CVE-2025-39779 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: subpage: keep TOWRITE tag until folio is cleanedbtrfs_subpage_set_writeback() calls folio_start_writeback() the first timea folio is written back, and it also clears the PAGECACHE_TAG_TOWRITE tageven if there are still dirty blocks in the folio. This can break orderingguarantees, such as those required by btrfs_wait_ordered_extents().That ordering breakage leads to a real failure. For example, runninggeneric/464 on a zoned setup will hit the following ASSERT. This happensbecause the broken ordering fails to flush existing dirty pages before thefile size is truncated. assertion failed: !list_empty(&ordered->list) :: 0, in fs/btrfs/zoned.c:1899 ------------[ cut here ]------------ kernel BUG at fs/btrfs/zoned.c:1899!

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

However, since both functionscontend for j_list_lock, the combined time spent waiting and processingcan be significant.jbd2_journal_shrink_checkpoint_list() explicitly calls cond_resched() whenneed_resched() is true to avoid softlockups during prolonged operations.But jbd2_log_do_checkpoint() only exits its loop when need_resched() istrue, relying on potentially sleeping functions like __flush_batch() orwait_on_buffer() to trigger rescheduling.

Description: In the Linux kernel, the following vulnerability has been resolved:bnxt_en: Fix memory corruption when FW resources change during ifdownbnxt_set_dflt_rings() assumes that it is always called before any TC hasbeen created. So it doesn't take bp->num_tc into account and assumesthat it is always 0 or 1.In the FW resource or capability change scenario, the FW will returnflags in bnxt_hwrm_if_change() that will cause the driver toreinitialize and call bnxt_cancel_reservations(). This will lead tobnxt_init_dflt_ring_mode() calling bnxt_set_dflt_rings() and bp->num_tcmay be greater than 1. This will cause bp->tx_ring[] to be sized toosmall and cause memory corruption in bnxt_alloc_cp_rings().Fix it by properly scaling the TX rings by bp->num_tc in the codepaths mentioned above. Add 2 helper functions to determinebp->tx_nr_rings and bp->tx_nr_rings_per_tc.

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

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

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

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

CVE-2025-39824 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:HID: asus: fix UAF via HID_CLAIMED_INPUT validationAfter hid_hw_start() is called hidinput_connect() will eventually becalled to set up the device with the input layer since theHID_CONNECT_DEFAULT connect mask is used. During hidinput_connect()all input and output reports are processed and corresponding hid_inputsare allocated and configured via hidinput_configure_usages(). Thisprocess involves slot tagging report fields and configuring usagesby setting relevant bits in the capability bitmaps. However it is possiblethat the capability bitmaps are not set at all leading to the subsequenthidinput_has_been_populated() check to fail leading to the freeing of thehid_input and the underlying input device.This becomes problematic because a malicious HID device like aASUS ROG N-Key keyboard can trigger the above scenario via aspecially crafted descriptor which then leads to a user-after-freewhen the name of the freed input device is written to later on afterhid_hw_start().

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:batman-adv: fix OOB read/write in network-coding decodebatadv_nc_skb_decode_packet() trusts coded_len and checks only againstskb->len. XOR starts at sizeof(struct batadv_unicast_packet), reducingpayload headroom, and the source skb length is not verified, allowing anout-of-bounds read and a small out-of-bounds write.Validate that coded_len fits within the payload area of both destinationand source sk_buffs before XORing.

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

This is becausevmemmap_populate_compound_pages() is implemented in core MM code, whichdoes not handle synchronization of the top-level page tables. Instead,the core MM has historically relied on each architecture to perform thissynchronization manually.We're not the first party to encounter a crash caused by not-sync'd toplevel page tables: earlier this year, Gwan-gyeong Mun attempted to addressthe issue [1] [2] after hitting a kernel panic when x86 code accessed thevmemmap area before the corresponding top-level entries were synced. Atthat time, the issue was believed to be triggered only when struct pagewas enlarged for debugging purposes, and the patch did not get furtherupdates.It turns out that current approach of relying on each arch to handle thepage table sync manually is fragile because 1) it's easy to forget to syncthe top level page table, and 2) it's also easy to overlook that thekernel should not access the vmemmap and direct mapping areas before thesync.# The solution: Make page table sync more code robust and harder to missTo address this, Dave Hansen suggested [3] [4] introducing{pgd,p4d}_populate_kernel() for updating kernel portion of the page tablesand allow each architecture to explicitly perform synchronization wheninstalling top-level entries. With this approach, we no longer need toworry about missing the sync step, reducing the risk of futureregressions.The new interface reuses existing ARCH_PAGE_TABLE_SYNC_MASK,PGTBL_P*D_MODIFIED and arch_sync_kernel_mappings() facility used byvmalloc and ioremap to synchronize page tables.pgd_populate_kernel() looks like this:static inline void pgd_populate_kernel(unsigned long addr, pgd_t *pgd, p4d_t *p4d){ pgd_populate(&init_mm, pgd, p4d); if (ARCH_PAGE_TABLE_SYNC_MASK & PGTBL_PGD_MODIFIED) arch_sync_kernel_mappings(addr, addr);}It is worth noting that vmalloc() and apply_to_range() carefullysynchronizes page tables by calling p*d_alloc_track() andarch_sync_kernel_mappings(), and thus they are not affected by---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:ice: fix NULL access of tx->in_use in ice_ll_ts_intrRecent versions of the E810 firmware have support for an extra interrupt tohandle report of the "low latency" Tx timestamps coming from thespecialized low latency firmware interface. Instead of polling theregisters, software can wait until the low latency interrupt is fired.This logic makes use of the Tx timestamp tracking structure, ice_ptp_tx, asit uses the same "ready" bitmap to track which Tx timestamps complete.Unfortunately, the ice_ll_ts_intr() function does not check if thetracker is initialized before its first access. This results in NULLdereference or use-after-free bugs similar to the issues fixed in theice_ptp_ts_irq() function.Fix this by only checking the in_use bitmap (and other fields) if thetracker is marked as initialized. The reset flow will clear the init fieldunder lock before it tears the tracker down, thus preventing anyuse-after-free or NULL access.

CVE-2025-39861 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: vhci: Prevent use-after-free by removing debugfs files earlyMove the creation of debugfs files into a dedicated function, and ensurethey are explicitly removed during vhci_release(), before associateddata structures are freed.Previously, debugfs files such as "force_suspend", "force_wakeup", andothers were created under hdev->debugfs but not removed invhci_release(). Since vhci_release() frees the backing vhci_datastructure, any access to these files after release would result inuse-after-free errors.Although hdev->debugfs is later freed in hci_release_dev(), user canaccess files after vhci_data is freed but before hdev->debugfs isreleased.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:dmaengine: ti: edma: Fix memory allocation size for queue_priority_mapFix a critical memory allocation bug in edma_setup_from_hw() wherequeue_priority_map was allocated with insufficient memory. The codedeclared queue_priority_map as s8 (*)[2] (pointer to array of 2 s8),but allocated memory using sizeof(s8) instead of the correct size.This caused out-of-bounds memory writes when accessing: queue_priority_map[i][0] = i; queue_priority_map[i][1] = i;The bug manifested as kernel crashes with "Oops - undefined instruction"on ARM platforms (BeagleBoard-X15) during EDMA driver probe, as thememory corruption triggered kernel hardening features on Clang.Change the allocation to use sizeof(*queue_priority_map) whichautomatically gets the correct size for the 2D array structure.

Description: In the Linux kernel, the following vulnerability has been resolved:dmaengine: idxd: Fix double free in idxd_setup_wqs()The clean up in idxd_setup_wqs() has had a couple bugs because the errorhandling is a bit subtle. It's simpler to just re-write it in a cleanerway. The issues here are:1) If "idxd->max_wqs" is <= 0 then we call put_device(conf_dev) when "conf_dev" hasn't been initialized.2) If kzalloc_node() fails then again "conf_dev" is invalid. It's either uninitialized or it points to the "conf_dev" from the previous iteration so it leads to a double free.It's better to free partial loop iterations within the loop and thenthe unwinding at the end can handle whole loop iterations. I alsorenamed the labels to describe what the goto does and not where the gotowas located.

This ends up being fairly benign because theside effect is just the invalidation of the authorizer and successivefetching of new tickets.con->v1.connect_seq overlaps with con->v2.conn_bufs and the fact thatit's being written to can cause more serious consequences, but luckilyit's not something that happens often.

When cgroup.pressure is disabled (echo 0 > cgroup.pressure), it: - Releases PSI triggers via cgroup_file_release() - Frees of->priv through kernfs_drain_open_files()2. While epoll still holds reference to the file and continues polling3.

This function will fail if the open filehas been released. Replace kernfs_get_active() with kernfs_get_active_of()to prevent further operations on released file descriptors.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:mm/damon/lru_sort: avoid divide-by-zero in damon_lru_sort_apply_parameters()Patch series "mm/damon: avoid divide-by-zero in DAMON module's parametersapplication".DAMON's RECLAIM and LRU_SORT modules perform no validation onuser-configured parameters during application, which may lead todivision-by-zero errors.Avoid the divide-by-zero by adding validation checks when DAMON modulesattempt to apply the parameters.This patch (of 2):During the calculation of 'hot_thres' and 'cold_thres', either'sample_interval' or 'aggr_interval' is used as the divisor, which maylead to division-by-zero errors. Fix it by directly returning -EINVALwhen such a case occurs. Additionally, since 'aggr_interval' is alreadyrequired to be set no smaller than 'sample_interval' in damon_set_attrs(),only the case where 'sample_interval' is zero needs to be checked.

CVE-2025-39910 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm/vmalloc, mm/kasan: respect gfp mask in kasan_populate_vmalloc()kasan_populate_vmalloc() and its helpers ignore the caller's gfp_mask andalways allocate memory using the hardcoded GFP_KERNEL flag. This makesthem inconsistent with vmalloc(), which was recently extended to supportGFP_NOFS and GFP_NOIO allocations.Page table allocations performed during shadow population also ignore theexternal gfp_mask. To preserve the intended semantics of GFP_NOFS andGFP_NOIO, wrap the apply_to_page_range() calls into the appropriatememalloc scope.xfs calls vmalloc with GFP_NOFS, so this bug could lead to deadlock.There was a report herehttps://lkml.kernel.org/r/686ea951.050a0220.385921.0016.GAE@google.comThis patch: - Extends kasan_populate_vmalloc() and helpers to take gfp_mask; - Passes gfp_mask down to alloc_pages_bulk() and __get_free_page(); - Enforces GFP_NOFS/NOIO semantics with memalloc_*_save()/restore() around apply_to_page_range(); - Updates vmalloc.c and percpu allocator call sites accordingly.

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

Otherwise, the extra ref on "structj1939_priv" held by j1939_sk_bind() call prevents "struct net_device" fromdropping the usage count to 1; making it impossible forunregister_netdevice() to continue.[mkl: remove space in front of label]

Retrying the parsing isfine in itself but since we copy some more data each timebefore we parse we can overflow the allocated skb space.Constructing a scenario in which we're under pressure withoutenough data in the socket to parse the length upfront is quitehard. syzbot figured out a way to do this by serving us the headerin small OOB sends, and then filling in the recvbuf with a largenormal send.Make sure that tls_rx_msg_size() aborts strp, if we reachan invalid record there's really no way to recover.

The only checkwhich is performed by the PF_PACKET framework is to make sure thatskb->len fits the interface's MTU.Unfortunately, because the mcba_usb driver does not populate itsnet_device_ops->ndo_change_mtu(), it is possible for an attacker toconfigure an invalid MTU by doing, for example: $ ip link set can0 mtu 9999After doing so, the attacker could open a PF_PACKET socket using theETH_P_CANXL protocol: socket(PF_PACKET, SOCK_RAW, htons(ETH_P_CANXL))to inject a malicious CAN XL frames. For example: struct canxl_frame frame = { .flags = 0xff, .len = 2048, };The CAN drivers' xmit() function are calling can_dev_dropped_skb() tocheck that the skb is valid, unfortunately under above conditions, themalicious packet is able to go through can_dev_dropped_skb() checks: 1. the skb->protocol is set to ETH_P_CANXL which is valid (the function does not check the actual device capabilities). 2. the length is a valid CAN XL length.And so, mcba_usb_start_xmit() receives a CAN XL frame which it is notable to correctly handle and will thus misinterpret it as a CAN frame.This can result in a buffer overflow.

During probe,imon_init_intf0 or imon_init_intf1 increments the usb_devicereference count depending on the interface. However, duringdisconnect, usb_put_dev is called unconditionally, regardless ofactual usage.As a result, if vfd_write or other operations are still inprogress after disconnect, this can lead to a use-after-free ofthe usb_device pointer.Thread 1 vfd_write Thread 2 imon_disconnect ... if usb_put_dev(ictx->usbdev_intf0) else usb_put_dev(ictx->usbdev_intf1)...while send_packet if pipe = usb_sndintpipe( ictx->usbdev_intf0) UAF else pipe = usb_sndctrlpipe( ictx->usbdev_intf0, 0) UAFGuard access to usbdev_intf0 and usbdev_intf1 after disconnect bychecking ictx->disconnected in all writer paths.

CVE-2025-39994 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:media: tuner: xc5000: Fix use-after-free in xc5000_releaseThe original code uses cancel_delayed_work() in xc5000_release(), whichdoes not guarantee that the delayed work item timer_sleep has fullycompleted if it was already running. This leads to use-after-free scenarioswhere xc5000_release() may free the xc5000_priv while timer_sleep is stillactive and attempts to dereference the xc5000_priv.A typical race condition is illustrated below:CPU 0 (release thread) | CPU 1 (delayed work callback)xc5000_release() | xc5000_do_timer_sleep() cancel_delayed_work() | hybrid_tuner_release_state(priv) | kfree(priv) | | priv = container_of() // UAFReplace cancel_delayed_work() with cancel_delayed_work_sync() to ensurethat the timer_sleep is properly canceled before the xc5000_priv memoryis deallocated.A deadlock concern was considered: xc5000_release() is called in a processcontext and is not holding any locks that the timer_sleep work item mightalso need. Therefore, the use of the _sync() variant is safe here.This bug was initially identified through static analysis.[hverkuil: fix typo in Subject: tunner -> tuner]

Description: In the Linux kernel, the following vulnerability has been resolved:media: i2c: tc358743: Fix use-after-free bugs caused by orphan timer in probeThe state->timer is a cyclic timer that schedules work_i2c_poll anddelayed_work_enable_hotplug, while rearming itself.

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-audio: fix race condition to UAF in snd_usbmidi_freeThe previous commit 0718a78f6a9f ("ALSA: usb-audio: Kill timer properly atremoval") patched a UAF issue caused by the error timer.However, because the error timer kill added in this patch occurs after theendpoint delete, a race condition to UAF still occurs, albeit rarely.Additionally, since kill-cleanup for urb is also missing, freed memory canbe accessed in interrupt context related to urb, which can cause UAF.Therefore, to prevent this, error timer and urb must be killed beforefreeing the heap memory.

Specifically, a VMA which has a valid pointerto vma->vm_userfaultfd_ctx, but no UFFD flags in vma->vm_flags.The inconsistency is caused in ksm_madvise(): when user calls madvise()with MADV_UNMEARGEABLE on a VMA that is registered for UFFD in MINOR mode,it accidentally clears all flags stored in the upper 32 bits ofvma->vm_flags.Assuming x86_64 kernel build, unsigned long is 64-bit and unsigned int andint are 32-bit wide. This setup causes the following mishap during the &=~VM_MERGEABLE assignment.VM_MERGEABLE is a 32-bit constant of type unsigned int, 0x8000'0000. After ~ is applied, it becomes 0x7fff'ffff unsigned int, which is thenpromoted to unsigned long before the & operation. This promotion fillsupper 32 bits with leading 0s, as we're doing unsigned conversion (andeven for a signed conversion, this wouldn't help as the leading bit is 0).& operation thus ends up AND-ing vm_flags with 0x0000'0000'7fff'ffffinstead of intended 0xffff'ffff'7fff'ffff and hence accidentally clearsthe upper 32-bits of its value.Fix it by changing `VM_MERGEABLE` constant to unsigned long, using theBIT() macro.Note: other VM_* flags are not affected: This only happens to theVM_MERGEABLE flag, as the other VM_* flags are all constants of type intand after ~ operation, they end up with leading 1 and are thus convertedto unsigned long with leading 1s.Note 2:After commit 31defc3b01d9 ("userfaultfd: remove (VM_)BUG_ON()s"), this isno longer a kernel BUG, but a WARNING at the same place:[ 45.595973] WARNING: CPU: 1 PID: 2474 at mm/userfaultfd.c:2067but the root-cause (flag-drop) remains the same.[akpm@linux-foundation.org: rust bindgen wasn't able to handle BIT(), from Miguel]

CVE-2025-40048 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:uio_hv_generic: Let userspace take care of interrupt maskRemove the logic to set interrupt mask by default in uio_hv_genericdriver as the interrupt mask value is supposed to be controlledcompletely by the user space. If the mask bit gets changedby the driver, concurrently with user mode operating on the ring,the mask bit may be set when it is supposed to be clear, and theuser-mode driver will miss an interrupt which will cause a hang.For eg- when the driver sets inbound ring buffer interrupt mask to 1,the host does not interrupt the guest on the UIO VMBus channel.However, setting the mask does not prevent the host from putting amessage in the inbound ring buffer. So let's assume that happens,the host puts a message into the ring buffer but does not interrupt.Subsequently, the user space code in the guest sets the inbound ringbuffer interrupt mask to 0, saying "Hey, I'm ready for interrupts".User space code then calls pread() to wait for an interrupt.Then one of two things happens:* The host never sends another message. So the pread() waits forever.* The host does send another message. But because there's already a message in the ring buffer, it doesn't generate an interrupt. This is the correct behavior, because the host should only send an interrupt when the inbound ring buffer transitions from empty to not-empty. Adding an additional message to a ring buffer that is not empty is not supposed to generate an interrupt on the guest. Since the guest is waiting in pread() and not removing messages from the ring buffer, the pread() waits forever.This could be easily reproduced in hv_fcopy_uio_daemon if we delaysetting interrupt mask to 0.Similarly if hv_uio_channel_cb() sets the interrupt_mask to 1,there's a race condition. Once user space empties the inbound ringbuffer, but before user space sets interrupt_mask to 0, the host couldput another message in the ring buffer but it wouldn't interrupt.Then the next pread() would hang.Fix these by removing all instances where interrupt_mask is changed,while keeping the one in set_event() unchanged to enable userspacecontrol the interrupt mask by writing 0/1 to /dev/uioX.

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

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

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

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

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

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

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

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

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

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

CVE-2025-40107 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:can: hi311x: fix null pointer dereference when resuming from sleep before interface was enabledThis issue is similar to the vulnerability in the `mcp251x` driver,which was fixed in commit 03c427147b2d ("can: mcp251x: fix resume fromsleep before interface was brought up").In the `hi311x` driver, when the device resumes from sleep, the driverschedules `priv->restart_work`. However, if the network interface wasnot previously enabled, the `priv->wq` (workqueue) is not allocated andinitialized, leading to a null pointer dereference.To fix this, we move the allocation and initialization of the workqueuefrom the `hi3110_open` function to the `hi3110_can_probe` function.This ensures that the workqueue is properly initialized before it isused during device resume. And added logic to destroy the workqueuein the error handling paths of `hi3110_can_probe` and in the`hi3110_can_remove` function to prevent resource leaks.

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:sparc: fix accurate exception reporting in copy_{from_to}_user for UltraSPARC IIIAnthony Yznaga tracked down that a BUG_ON in ext4 code with large foliosenabled resulted from copy_from_user() returning impossibly large valuesgreater than the size to be copied. This lead to __copy_from_iter()returning impossible values instead of the actual number of bytes it wasable to copy.The BUG_ON has been reported inhttps://lore.kernel.org/r/b14f55642207e63e907965e209f6323a0df6dcee.camel@physik.fu-berlin.deThe referenced commit introduced exception handlers on user-space memoryreferences in copy_from_user and copy_to_user. These handlers return fromthe respective function and calculate the remaining bytes left to copyusing the current register contents. The exception handlers expect that%o2 has already been masked during the bulk copy loop, but the masking wasperformed after that loop. This will fix the return value of copy_from_userand copy_to_user in the faulting case. The behaviour of memcpy staysunchanged.

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: detect invalid INLINE_DATA + EXTENTS flag combinationsyzbot reported a BUG_ON in ext4_es_cache_extent() when opening a verityfile on a corrupted ext4 filesystem mounted without a journal.The issue is that the filesystem has an inode with both the INLINE_DATAand EXTENTS flags set: EXT4-fs error (device loop0): ext4_cache_extents:545: inode #15: comm syz.0.17: corrupted extent tree: lblk 0 < prev 66Investigation revealed that the inode has both flags set: DEBUG: inode 15 - flag=1, i_inline_off=164, has_inline=1, extents_flag=1This is an invalid combination since an inode should have either:- INLINE_DATA: data stored directly in the inode- EXTENTS: data stored in extent-mapped blocksHaving both flags causes ext4_has_inline_data() to return true, skippingextent tree validation in __ext4_iget(). The unvalidated out-of-orderextents then trigger a BUG_ON in ext4_es_cache_extent() due to integerunderflow when calculating hole sizes.Fix this by detecting this invalid flag combination early in ext4_iget()and rejecting the corrupted inode.

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

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

If tsk != current and tsk is not a leader, this process can exit/execand task_lock(tsk->group_leader) may use the already freed task_struct.Another problem is that sys_prlimit64() can race with mt-exec which changes->group_leader. In this case do_prlimit() may take the wrong lock, or (worse)->group_leader may change between task_lock() and task_unlock().Change sys_prlimit64() to take tasklist_lock when necessary.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: avoid potential out-of-bounds in btrfs_encode_fh()The function btrfs_encode_fh() does not properly account for the threecases it handles.Before writing to the file handle (fh), the function only returns to theuser BTRFS_FID_SIZE_NON_CONNECTABLE (5 dwords, 20 bytes) orBTRFS_FID_SIZE_CONNECTABLE (8 dwords, 32 bytes).However, when a parent exists and the root ID of the parent and theinode are different, the function writes BTRFS_FID_SIZE_CONNECTABLE_ROOT(10 dwords, 40 bytes).If *max_len is not large enough, this write goes out of bounds becauseBTRFS_FID_SIZE_CONNECTABLE_ROOT is greater thanBTRFS_FID_SIZE_CONNECTABLE originally returned.This results in an 8-byte out-of-bounds write atfid->parent_root_objectid = parent_root_id.A previous attempt to fix this issue was made but was lost.https://lore.kernel.org/all/4CADAEEC020000780001B32C@vpn.id2.novell.com/Although this issue does not seem to be easily triggerable, it is apotential memory corruption bug that should be fixed. This patchresolves the issue by ensuring the function returns the appropriate sizefor all three cases and validates that *max_len is large enough beforewriting any data.

CVE-2025-40218 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm/damon/vaddr: do not repeat pte_offset_map_lock() until successDAMON's virtual address space operation set implementation (vaddr) callspte_offset_map_lock() inside the page table walk callback function. Thisis for reading and writing page table accessed bits. Ifpte_offset_map_lock() fails, it retries by returning the page table walkcallback function with ACTION_AGAIN.pte_offset_map_lock() can continuously fail if the target is a pmdmigration entry, though. Hence it could cause an infinite page table walkif the migration cannot be done until the page table walk is finished. This indeed caused a soft lockup when CPU hotplugging and DAMON wererunning in parallel.Avoid the infinite loop by simply not retrying the page table walk. DAMONis promising only a best-effort accuracy, so missing access to such pagesis no problem.

CVE-2025-40230 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm: prevent poison consumption when splitting THPWhen performing memory error injection on a THP (Transparent Huge Page)mapped to userspace on an x86 server, the kernel panics with the followingtrace. The expected behavior is to terminate the affected process insteadof panicking the kernel, as the x86 Machine Check code can recover from anin-userspace #MC. mce: [Hardware Error]: CPU 0: Machine Check Exception: f Bank 3: bd80000000070134 mce: [Hardware Error]: RIP 10: {memchr_inv+0x4c/0xf0} mce: [Hardware Error]: TSC afff7bbff88a ADDR 1d301b000 MISC 80 PPIN 1e741e77539027db mce: [Hardware Error]: PROCESSOR 0:d06d0 TIME 1758093249 SOCKET 0 APIC 0 microcode 80000320 mce: [Hardware Error]: Run the above through 'mcelog --ascii' mce: [Hardware Error]: Machine check: Data load in unrecoverable area of kernel Kernel panic - not syncing: Fatal local machine checkThe root cause of this panic is that handling a memory failure triggeredby an in-userspace #MC necessitates splitting the THP. The splittingprocess employs a mechanism, implemented intry_to_map_unused_to_zeropage(), which reads the pages in the THP toidentify zero-filled pages. However, reading the pages in the THP resultsin a second in-kernel #MC, occurring before the initial memory_failure()completes, ultimately leading to a kernel panic. See the kernel paniccall trace on the two #MCs. First Machine Check occurs // [1] memory_failure() // [2] try_to_split_thp_page() split_huge_page() split_huge_page_to_list_to_order() __folio_split() // [3] remap_page() remove_migration_ptes() remove_migration_pte() try_to_map_unused_to_zeropage() // [4] memchr_inv() // [5] Second Machine Check occurs // [6] Kernel panic[1] Triggered by accessing a hardware-poisoned THP in userspace, which is typically recoverable by terminating the affected process.[2] Call folio_set_has_hwpoisoned() before try_to_split_thp_page().[3] Pass the RMP_USE_SHARED_ZEROPAGE remap flag to remap_page().[4] Try to map the unused THP to zeropage.[5] Re-access pages in the hw-poisoned THP in the kernel.[6] Triggered in-kernel, leading to a panic kernel.In Step[2], memory_failure() sets the poisoned flag on the page in the THPby TestSetPageHWPoison() before calling try_to_split_thp_page().As suggested by David Hildenbrand, fix this panic by not accessing to thepoisoned page in the THP during zeropage identification, while continuingto scan unaffected pages in the THP for possible zeropage mapping. Thisprevents a second in-kernel #MC that would cause kernel panic in Step[4].Thanks to Andrew Zaborowski for his initial work on fixing this issue.

CVE-2025-40233 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ocfs2: clear extent cache after moving/defragmenting extentsThe extent map cache can become stale when extents are moved ordefragmented, causing subsequent operations to see outdated extent flags. This triggers a BUG_ON in ocfs2_refcount_cal_cow_clusters().The problem occurs when:1. copy_file_range() creates a reflinked extent with OCFS2_EXT_REFCOUNTED2. ioctl(FITRIM) triggers ocfs2_move_extents()3. __ocfs2_move_extents_range() reads and caches the extent (flags=0x2)4. ocfs2_move_extent()/ocfs2_defrag_extent() calls __ocfs2_move_extent() which clears OCFS2_EXT_REFCOUNTED flag on disk (flags=0x0)5. The extent map cache is not invalidated after the move6. Later write() operations read stale cached flags (0x2) but disk has updated flags (0x0), causing a mismatch7. BUG_ON(!(rec->e_flags & OCFS2_EXT_REFCOUNTED)) triggersFix by clearing the extent map cache after each extent move/defragoperation in __ocfs2_move_extents_range(). This ensures subsequentoperations read fresh extent data from disk.

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

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

This commitmodifies the cleanup to remove only the specific IRQ mapping that wasjust added.This prevents removal of other valid mappings and ensures precisecleanup of the failed IRQ allocation's associated glue object.Note: This error is observed when both fwctl and rds configs are enabled.[1]mlx5_core 0000:05:00.0: Successfully registered panic handler for port 1mlx5_core 0000:05:00.0: mlx5_irq_alloc:293:(pid 66740): Failed torequest irq. err = -28infiniband mlx5_0: mlx5_ib_test_wc:290:(pid 66740): Error -28 whiletrying to test write-combining supportmlx5_core 0000:05:00.0: Successfully unregistered panic handler for port 1mlx5_core 0000:06:00.0: Successfully registered panic handler for port 1mlx5_core 0000:06:00.0: mlx5_irq_alloc:293:(pid 66740): Failed torequest irq. err = -28infiniband mlx5_0: mlx5_ib_test_wc:290:(pid 66740): Error -28 whiletrying to test write-combining supportmlx5_core 0000:06:00.0: Successfully unregistered panic handler for port 1mlx5_core 0000:03:00.0: mlx5_irq_alloc:293:(pid 28895): Failed torequest irq. err = -28mlx5_core 0000:05:00.0: mlx5_irq_alloc:293:(pid 28895): Failed torequest irq. err = -28general protection fault, probably for non-canonical address0xe277a58fde16f291: 0000 [#1] SMP NOPTIRIP: 0010:free_irq_cpu_rmap+0x23/0x7dCall Trace: ? show_trace_log_lvl+0x1d6/0x2f9 ? show_trace_log_lvl+0x1d6/0x2f9 ? mlx5_irq_alloc.cold+0x5d/0xf3 [mlx5_core] ? __die_body.cold+0x8/0xa ? die_addr+0x39/0x53 ? exc_general_protection+0x1c4/0x3e9 ? dev_vprintk_emit+0x5f/0x90 ? asm_exc_general_protection+0x22/0x27 ? free_irq_cpu_rmap+0x23/0x7d mlx5_irq_alloc.cold+0x5d/0xf3 [mlx5_core] irq_pool_request_vector+0x7d/0x90 [mlx5_core] mlx5_irq_request+0x2e/0xe0 [mlx5_core] mlx5_irq_request_vector+0xad/0xf7 [mlx5_core] comp_irq_request_pci+0x64/0xf0 [mlx5_core] create_comp_eq+0x71/0x385 [mlx5_core] ? mlx5e_open_xdpsq+0x11c/0x230 [mlx5_core] mlx5_comp_eqn_get+0x72/0x90 [mlx5_core] ? xas_load+0x8/0x91 mlx5_comp_irqn_get+0x40/0x90 [mlx5_core] mlx5e_open_channel+0x7d/0x3c7 [mlx5_core] mlx5e_open_channels+0xad/0x250 [mlx5_core] mlx5e_open_locked+0x3e/0x110 [mlx5_core] mlx5e_open+0x23/0x70 [mlx5_core] __dev_open+0xf1/0x1a5 __dev_change_flags+0x1e1/0x249 dev_change_flags+0x21/0x5c do_setlink+0x28b/0xcc4 ? __nla_parse+0x22/0x3d ? inet6_validate_link_af+0x6b/0x108 ? cpumask_next+0x1f/0x35 ? __snmp6_fill_stats64.constprop.0+0x66/0x107 ? __nla_validate_parse+0x48/0x1e6 __rtnl_newlink+0x5ff/0xa57 ? kmem_cache_alloc_trace+0x164/0x2ce rtnl_newlink+0x44/0x6e rtnetlink_rcv_msg+0x2bb/0x362 ? __netlink_sendskb+0x4c/0x6c ? netlink_unicast+0x28f/0x2ce ? rtnl_calcit.isra.0+0x150/0x146 netlink_rcv_skb+0x5f/0x112 netlink_unicast+0x213/0x2ce netlink_sendmsg+0x24f/0x4d9 __sock_sendmsg+0x65/0x6a ____sys_sendmsg+0x28f/0x2c9 ? import_iovec+0x17/0x2b ___sys_sendmsg+0x97/0xe0 __sys_sendmsg+0x81/0xd8 do_syscall_64+0x35/0x87 entry_SYSCALL_64_after_hwframe+0x6e/0x0RIP: 0033:0x7fc328603727Code: c3 66 90 41 54 41 89 d4 55 48 89 f5 53 89 fb 48 83 ec 10 e8 0b edff ff 44 89 e2 48 89 ee 89 df 41 89 c0 b8 2e 00 00 00 0f 05 <48> 3d 00f0 ff ff 77 35 44 89 c7 48 89 44 24 08 e8 44 ed ff ff 48RSP: 002b:00007ffe8eb3f1a0 EFLAGS: 00000293 ORIG_RAX: 000000000000002eRAX: ffffffffffffffda RBX: 000000000000000d RCX: 00007fc328603727RDX: 0000000000000000 RSI: 00007ffe8eb3f1f0 RDI: 000000000000000dRBP: 00007ffe8eb3f1f0 R08: 0000000000000000 R09: 0000000000000000R10: 0000000000000000 R11: 0000000000000293 R12: 0000000000000000R13: 00000000000---truncated---

CVE-2025-40251 Severity: Moderate CVSS3 score: 5.5

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

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

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

CVE-2025-40341 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-2025-40346 Severity: Moderate CVSS3 score: 5.5

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

Description: In the Linux kernel, the following vulnerability has been resolved:net: enetc: fix the deadlock of enetc_mdio_lockAfter applying the workaround for err050089, the LS1028A platformexperiences RCU stalls on RT kernel. This issue is caused by therecursive acquisition of the read lock enetc_mdio_lock. Here list someof the call stacks identified under the enetc_poll path that may lead toa deadlock:enetc_poll -> enetc_lock_mdio -> enetc_clean_rx_ring OR napi_complete_done -> napi_gro_receive -> enetc_start_xmit -> enetc_lock_mdio -> enetc_map_tx_buffs -> enetc_unlock_mdio -> enetc_unlock_mdioAfter enetc_poll acquires the read lock, a higher-priority writer attemptsto acquire the lock, causing preemption. The writer detects that aread lock is already held and is scheduled out. However, readers underenetc_poll cannot acquire the read lock again because a writer is alreadywaiting, leading to a thread hang.Currently, the deadlock is avoided by adjusting enetc_lock_mdio to preventrecursive lock acquisition.

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

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

Meanwhile,consider that blkcg_mutex is held after queue is freezed from policydeactivation, also convert blkg_alloc() to use GFP_NOIO.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:ring-buffer: Do not warn in ring_buffer_map_get_reader() when reader catches upThe function ring_buffer_map_get_reader() is a bit more strict than theother get reader functions, and except for certain situations therb_get_reader_page() should not return NULL. If it does, it triggers awarning.This warning was triggering but after looking at why, it was becauseanother acceptable situation was happening and it wasn't checked for.If the reader catches up to the writer and there's still data to be readon the reader page, then the rb_get_reader_page() will return NULL asthere's no new page to get.In this situation, the reader page should not be updated and no warningshould trigger.

Description: In the Linux kernel, the following vulnerability has been resolved:codetag: debug: handle existing CODETAG_EMPTY in mark_objexts_empty for slabobj_extWhen alloc_slab_obj_exts() fails and then later succeeds in allocating aslab extension vector, it calls handle_failed_objexts_alloc() to mark allobjects in the vector as empty. As a result all objects in this slab(slabA) will have their extensions set to CODETAG_EMPTY.Later on if this slabA is used to allocate a slabobj_ext vector foranother slab (slabB), we end up with the slabB->obj_exts pointing to aslabobj_ext vector that itself has a non-NULL slabobj_ext equal toCODETAG_EMPTY. When slabB gets freed, free_slab_obj_exts() is called tofree slabB->obj_exts vector. free_slab_obj_exts() calls mark_objexts_empty(slabB->obj_exts) which willgenerate a warning because it expects slabobj_ext vectors to have a NULLobj_ext, not CODETAG_EMPTY.Modify mark_objexts_empty() to skip the warning and setting the obj_extvalue if it's already set to CODETAG_EMPTY.To quickly detect this WARN, I modified the code fromWARN_ON(slab_exts[offs].ref.ct) to BUG_ON(slab_exts[offs].ref.ct == 1);We then obtained this message:[21630.898561] ------------[ cut here ]------------[21630.898596] kernel BUG at mm/slub.c:2050![21630.898611] Internal error: Oops - BUG: 00000000f2000800 [#1] SMP[21630.900372] Modules linked in: squashfs isofs vfio_iommu_type1 vhost_vsock vfio vhost_net vmw_vsock_virtio_transport_common vhost tap vhost_iotlb iommufd vsock binfmt_misc nfsv3 nfs_acl nfs lockd grace netfs tls rds dns_resolver tun brd overlay ntfs3 exfat btrfs blake2b_generic xor xor_neon raid6_pq loop sctp ip6_udp_tunnel udp_tunnel nft_fib_inet nft_fib_ipv4 nft_fib_ipv6 nft_fib nft_reject_inet nf_reject_ipv4 nf_reject_ipv6 nft_reject nft_ct nft_chain_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 nf_tables rfkill ip_set sunrpc vfat fat joydev sg sch_fq_codel nfnetlink virtio_gpu sr_mod cdrom drm_client_lib virtio_dma_buf drm_shmem_helper drm_kms_helper drm ghash_ce backlight virtio_net virtio_blk virtio_scsi net_failover virtio_console failover virtio_mmio dm_mirror dm_region_hash dm_log dm_multipath dm_mod fuse i2c_dev virtio_pci virtio_pci_legacy_dev virtio_pci_modern_dev virtio virtio_ring autofs4 aes_neon_bs aes_ce_blk [last unloaded: hwpoison_inject][21630.909177] CPU: 3 UID: 0 PID: 3787 Comm: kylin-process-m Kdump: loaded Tainted: G W 6.18.0-rc1+ #74 PREEMPT(voluntary)[21630.910495] Tainted: [W]=WARN[21630.910867] Hardware name: QEMU KVM Virtual Machine, BIOS unknown 2/2/2022[21630.911625] pstate: 80400005 (Nzcv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--)[21630.912392] pc : __free_slab+0x228/0x250[21630.912868] lr : __free_slab+0x18c/0x250[21630.913334] sp : ffff8000a02f73e0[21630.913830] x29: ffff8000a02f73e0 x28: fffffdffc43fc800 x27: ffff0000c0011c40[21630.914677] x26: ffff0000c000cac0 x25: ffff00010fe5e5f0 x24: ffff000102199b40[21630.915469] x23: 0000000000000003 x22: 0000000000000003 x21: ffff0000c0011c40[21630.916259] x20: fffffdffc4086600 x19: fffffdffc43fc800 x18: 0000000000000000[21630.917048] x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000000000[21630.917837] x14: 0000000000000000 x13: 0000000000000000 x12: ffff70001405ee66[21630.918640] x11: 1ffff0001405ee65 x10: ffff70001405ee65 x9 : ffff800080a295dc[21630.919442] x8 : ffff8000a02f7330 x7 : 0000000000000000 x6 : 0000000000003000[21630.920232] x5 : 0000000024924925 x4 : 0000000000000001 x3 : 0000000000000007[21630.921021] x2 : 0000000000001b40 x1 : 000000000000001f x0 : 0000000000000001[21630.921810] Call trace:[21630.922130] __free_slab+0x228/0x250 (P)[21630.922669] free_slab+0x38/0x118[21630.923079] free_to_partial_list+0x1d4/0x340[21630.923591] __slab_free+0x24c/0x348[21630.924024] ___cache_free+0xf0/0x110[21630.924468] qlist_free_all+0x78/0x130[21630.924922] kasan_quarantine_reduce+0x11---truncated---

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:binfmt_misc: restore write access before closing files opened by open_exec()bm_register_write() opens an executable file using open_exec(), whichinternally calls do_open_execat() and denies write access on the file toavoid modification while it is being executed.However, when an error occurs, bm_register_write() closes the file usingfilp_close() directly. This does not restore the write permission, whichmay cause subsequent write operations on the same file to fail.Fix this by calling exe_file_allow_write_access() before filp_close() torestore the write permission properly.

CVE-2025-68245 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: netpoll: fix incorrect refcount handling causing incorrect cleanupcommit efa95b01da18 ("netpoll: fix use after free") incorrectlyignored the refcount and prematurely set dev->npinfo to NULL duringnetpoll cleanup, leading to improper behavior and memory leaks.Scenario causing lack of proper cleanup:1) A netpoll is associated with a NIC (e.g., eth0) and netdev->npinfo is allocated, and refcnt = 1 - Keep in mind that npinfo is shared among all netpoll instances. In this case, there is just one.2) Another netpoll is also associated with the same NIC and npinfo->refcnt += 1. - Now dev->npinfo->refcnt = 2; - There is just one npinfo associated to the netdev.3) When the first netpolls goes to clean up: - The first cleanup succeeds and clears np->dev->npinfo, ignoring refcnt. - It basically calls `RCU_INIT_POINTER(np->dev->npinfo, NULL);` - Set dev->npinfo = NULL, without proper cleanup - No ->ndo_netpoll_cleanup() is either called4) Now the second target tries to clean up - The second cleanup fails because np->dev->npinfo is already NULL. * In this case, ops->ndo_netpoll_cleanup() was never called, and the skb pool is not cleaned as well (for the second netpoll instance) - This leaks npinfo and skbpool skbs, which is clearly reported by kmemleak.Revert commit efa95b01da18 ("netpoll: fix use after free") and addsclarifying comments emphasizing that npinfo cleanup should only happenonce the refcount reaches zero, ensuring stable and correct netpollbehavior.

CVE-2025-68259 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: SVM: Don't skip unrelated instruction if INT3/INTO is replacedWhen re-injecting a soft interrupt from an INT3, INT0, or (select) INTninstruction, discard the exception and retry the instruction if the codestream is changed (e.g. by a different vCPU) between when the CPUexecutes the instruction and when KVM decodes the instruction to get thenext RIP.As effectively predicted by commit 6ef88d6e36c2 ("KVM: SVM: Re-injectINT3/INTO instead of retrying the instruction"), failure to verify thatthe correct INTn instruction was decoded can effectively clobber gueststate due to decoding the wrong instruction and thus specifying thewrong next RIP.The bug most often manifests as "Oops: int3" panics on static branchchecks in Linux guests. Enabling or disabling a static branch in Linuxuses the kernel's "text poke" code patching mechanism. To modify codewhile other CPUs may be executing that code, Linux (temporarily)replaces the first byte of the original instruction with an int3 (opcode0xcc), then patches in the new code stream except for the first byte,and finally replaces the int3 with the first byte of the new codestream. If a CPU hits the int3, i.e. executes the code while it's beingmodified, then the guest kernel must look up the RIP to determine how tohandle the #BP, e.g. by emulating the new instruction. If the RIP isincorrect, then this lookup fails and the guest kernel panics.The bug reproduces almost instantly by hacking the guest kernel torepeatedly check a static branch[1] while running a drgn script[2] onthe host to constantly swap out the memory containing the guest's TSS.[1]: https://gist.github.com/osandov/44d17c51c28c0ac998ea0334edf90b5a[2]: https://gist.github.com/osandov/10e45e45afa29b11e0c7209247afc00b

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-2025-68292 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:mm/memfd: fix information leak in hugetlb foliosWhen allocating hugetlb folios for memfd, three initialization steps aremissing:1. Folios are not zeroed, leading to kernel memory disclosure to userspace2. Folios are not marked uptodate before adding to page cache3. hugetlb_fault_mutex is not taken before hugetlb_add_to_page_cache()The memfd allocation path bypasses the normal page fault handler(hugetlb_no_page) which would handle all of these initialization steps. This is problematic especially for udmabuf use cases where folios arepinned and directly accessed by userspace via DMA.Fix by matching the initialization pattern used in hugetlb_no_page():- Zero the folio using folio_zero_user() which is optimized for huge pages- Mark it uptodate with folio_mark_uptodate()- Take hugetlb_fault_mutex before adding to page cache to prevent racesThe folio_zero_user() change also fixes a potential security issue whereuninitialized kernel memory could be disclosed to userspace through read()or mmap() operations on the memfd.

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

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

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

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

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

CVE-2025-68319 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:netconsole: Acquire su_mutex before navigating configs hierarchyThere is a race between operations that iterate over the userdatacg_children list and concurrent add/remove of userdata items throughconfigfs. The update_userdata() function iterates over thent->userdata_group.cg_children list, and count_extradata_entries() alsoiterates over this same list to count nodes.Quoting from Documentation/filesystems/configfs.rst:> A subsystem can navigate the cg_children list and the ci_parent pointer> to see the tree created by the subsystem. This can race with configfs'> management of the hierarchy, so configfs uses the subsystem mutex to> protect modifications. Whenever a subsystem wants to navigate the> hierarchy, it must do so under the protection of the subsystem> mutex.Without proper locking, if a userdata item is added or removedconcurrently while these functions are iterating, the list can beaccessed in an inconsistent state. For example, the list_for_each() loopcan reach a node that is being removed from the list by list_del_init()which sets the nodes' .next pointer to point to itself, so the loop willnever end (or reach the WARN_ON_ONCE in update_userdata() ).Fix this by holding the configfs subsystem mutex (su_mutex) during alloperations that iterate over cg_children.This includes:- userdatum_value_store() which calls update_userdata() to iterate over cg_children- All sysdata_*_enabled_store() functions which call count_extradata_entries() to iterate over cg_childrenThe su_mutex must be acquired before dynamic_netconsole_mutex to avoidpotential lock ordering issues, as configfs operations may already holdsu_mutex when calling into our code.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:tracing: Fix WARN_ON in tracing_buffers_mmap_close for split VMAsWhen a VMA is split (e.g., by partial munmap or MAP_FIXED), the kernelcalls vm_ops->close on each portion. For trace buffer mappings, thisresults in ring_buffer_unmap() being called multiple times whilering_buffer_map() was only called once.This causes ring_buffer_unmap() to return -ENODEV on subsequent callsbecause user_mapped is already 0, triggering a WARN_ON.Trace buffer mappings cannot support partial mappings because the ringbuffer structure requires the complete buffer including the meta page.Fix this by adding a may_split callback that returns -EINVAL to preventVMA splits entirely.

There have been many inconsistencies in the file systemdata.In the case of file system data inconsistency, for example, if the blockbitmap of a referenced block is not set, it can lead to the situation wherea block being committed is allocated and used again. As a result, thefollowing condition will not be satisfied then trigger BUG_ON. Of course,it is entirely possible to construct a problematic image that can triggerthis BUG_ON through specific operations. In fact, I have constructed suchan image and easily reproduced this issue.Therefore, J_ASSERT() holds true only under ideal conditions, but it maynot necessarily be satisfied in exceptional scenarios. Using J_ASSERT()directly in abnormal situations would cause the system to crash, which isclearly not what we want. So here we directly trigger a JBD abort insteadof immediately invoking BUG_ON.

For NAPI this is correctly handled as thenapi_schedule_prep() check will prevent multiple instances from gettingscheduled, but for the remaining code in veth_pool() this can runconcurrent with the newly started NAPI instance.The problem/race is that xdp_clear_return_frame_no_direct() isn'tdesigned to be nested.Prior to commit 401cb7dae813 ("net: Reference bpf_redirect_info viatask_struct on PREEMPT_RT.") the temporary BPF net contextbpf_redirect_info was stored per CPU, where this wasn't an issue. Sincethis commit the BPF context is stored in 'current' task_struct. Whenrunning veth in threaded-NAPI mode, then the kthread becomes the storagearea. Now a race exists between two concurrent veth_pool() function callsone exiting NAPI and one running new NAPI, both using the same BPF netcontext.Race is when another CPU gets within the xdp_set_return_frame_no_direct()section before exiting veth_pool() calls the clear-functionxdp_clear_return_frame_no_direct().

Description: In the Linux kernel, the following vulnerability has been resolved:block: fix memory leak in __blkdev_issue_zero_pagesMove the fatal signal check before bio_alloc() to prevent a memoryleak when BLKDEV_ZERO_KILLABLE is set and a fatal signal is pending.Previously, the bio was allocated before checking for a fatal signal.If a signal was pending, the code would break out of the loop withoutfreeing or chaining the just-allocated bio, causing a memory leak.This matches the pattern already used in __blkdev_issue_write_zeroes()where the signal check precedes the allocation.

CVE-2025-68356 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:gfs2: Prevent recursive memory reclaimFunction new_inode() returns a new inode with inode->i_mapping->gfp_maskset to GFP_HIGHUSER_MOVABLE. This value includes the __GFP_FS flag, soallocations in that address space can recurse into filesystem memoryreclaim. We don't want that to happen because it can consume asignificant amount of stack memory.Worse than that is that it can also deadlock: for example, in severalplaces, gfs2_unstuff_dinode() is called inside filesystem transactions.This calls filemap_grab_folio(), which can allocate a new folio, whichcan trigger memory reclaim. If memory reclaim recurses into thefilesystem and starts another transaction, a deadlock will ensue.To fix these kinds of problems, prevent memory reclaim from recursinginto filesystem code by making sure that the gfp_mask of inode addressspaces doesn't include __GFP_FS.The "meta" and resource group address spaces were already using GFP_NOFSas their gfp_mask (which doesn't include __GFP_FS). The default valueof GFP_HIGHUSER_MOVABLE is less restrictive than GFP_NOFS, though. Toavoid being overly limiting, use the default value and only knock offthe __GFP_FS flag. I'm not sure if this will actually make adifference, but it also shouldn't hurt.This patch is loosely based on commit ad22c7a043c2 ("xfs: prevent stackoverflows from page cache allocation").Fixes xfstest generic/273.

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

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

CVE-2025-68359 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix double free of qgroup record after failure to add delayed ref headIn the previous code it was possible to incur into a double kfree()scenario when calling add_delayed_ref_head(). This could happen if therecord was reported to already exist in thebtrfs_qgroup_trace_extent_nolock() call, but then there was an errorlater on add_delayed_ref_head(). In this case, sinceadd_delayed_ref_head() returned an error, the caller went to free therecord. Since add_delayed_ref_head() couldn't set this kfree'd pointerto NULL, then kfree() would have acted on a non-NULL 'record' objectwhich was pointing to memory already freed by the callee.The problem comes from the fact that the responsibility to kfree theobject is on both the caller and the callee at the same time. Hence, thefix for this is to shift the ownership of the 'qrecord' object out ofthe add_delayed_ref_head(). That is, we will never attempt to kfree()the given object inside of this function, and will expect the caller toact on the 'qrecord' object on its own. The only exception where the'qrecord' object cannot be kfree'd is if it was inserted into thetracing logic, for which we already have the 'qrecord_inserted_ret'boolean to account for this. Hence, the caller has to kfree the objectonly if add_delayed_ref_head() reports not to have inserted it on thetracing logic.As a side-effect of the above, we must guarantee that'qrecord_inserted_ret' is properly initialized at the start of thefunction, not at the end, and then set when an actual inserthappens. This way we avoid 'qrecord_inserted_ret' having an invalidvalue on an early exit.The documentation from the add_delayed_ref_head() has also been updatedto reflect on the exact ownership of the 'qrecord' object.

But theetr_buf that is being used by the ETR remains pointed to buf_old, notupdated to buf_new. In this case, it will result in a memoryuse-after-free issue.Fix this by checking ETR's mode before updating and releasing buf_old,if the mode is CS_MODE_SYSFS, then skip updating and releasing it.

CVE-2025-68431 Severity: Moderate CVSS3 score: 5.5

Description: libheif is an HEIF and AVIF file format decoder and encoder. Prior to version 1.21.0, a crafted HEIF that exercises the overlay image item path triggers a heap buffer over-read in `HeifPixelImage::overlay()`. The function computes a negative row length (likely from an unclipped overlay rectangle or invalid offsets), which then underflows when converted to `size_t` and is passed to `memcpy`, causing a very large read past the end of the source plane and a crash. Version 1.21.0 contains a patch. As a workaround, avoid decoding images using `iovl` overlay boxes.

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

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

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.

CVE-2025-68797 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:char: applicom: fix NULL pointer dereference in ac_ioctlDiscovered by Atuin - Automated Vulnerability Discovery Engine.In ac_ioctl, the validation of IndexCard and the check for a validRamIO pointer are skipped when cmd is 6. However, the functionunconditionally executes readb(apbs[IndexCard].RamIO + VERS) at theend.If cmd is 6, IndexCard may reference a board that does not exist(where RamIO is NULL), leading to a NULL pointer dereference.Fix this by skipping the readb access when cmd is 6, as thiscommand is a global information query and does not target a specificboard context.

CVE-2025-68809 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ksmbd: vfs: fix race on m_flags in vfs_cacheksmbd maintains delete-on-close and pending-delete state inksmbd_inode->m_flags. In vfs_cache.c this field is accessed underinconsistent locking: some paths read and modify m_flags underci->m_lock while others do so without taking the lock at all.Examples: - ksmbd_query_inode_status() and __ksmbd_inode_close() use ci->m_lock when checking or updating m_flags. - ksmbd_inode_pending_delete(), ksmbd_set_inode_pending_delete(), ksmbd_clear_inode_pending_delete() and ksmbd_fd_set_delete_on_close() used to read and modify m_flags without ci->m_lock.This creates a potential data race on m_flags when multiple threadsopen, close and delete the same file concurrently. In the worst casedelete-on-close and pending-delete bits can be lost or observed in aninconsistent state, leading to confusing delete semantics (files thatstay on disk after delete-on-close, or files that disappear while stillin use).Fix it by: - Making ksmbd_query_inode_status() look at m_flags under ci->m_lock after dropping inode_hash_lock. - Adding ci->m_lock protection to all helpers that read or modify m_flags (ksmbd_inode_pending_delete(), ksmbd_set_inode_pending_delete(), ksmbd_clear_inode_pending_delete(), ksmbd_fd_set_delete_on_close()). - Keeping the existing ci->m_lock protection in __ksmbd_inode_close(), and moving the actual unlink/xattr removal outside the lock.This unifies the locking around m_flags and removes the data race whilepreserving the existing delete-on-close behaviour.

CVE-2025-68810 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: Disallow toggling KVM_MEM_GUEST_MEMFD on an existing memslotReject attempts to disable KVM_MEM_GUEST_MEMFD on a memslot that wasinitially created with a guest_memfd binding, as KVM doesn't supporttoggling KVM_MEM_GUEST_MEMFD on existing memslots. KVM prevents enablingKVM_MEM_GUEST_MEMFD, but doesn't prevent clearing the flag.Failure to reject the new memslot results in a use-after-free due to KVMnot unbinding from the guest_memfd instance. Unbinding on a FLAGS_ONLYchange is easy enough, and can/will be done as a hardening measure (inanticipation of KVM supporting dirty logging on guest_memfd at some point),but fixing the use-after-free would only address the immediate symptom. ================================================================== BUG: KASAN: slab-use-after-free in kvm_gmem_release+0x362/0x400 [kvm] Write of size 8 at addr ffff8881111ae908 by task repro/745 CPU: 7 UID: 1000 PID: 745 Comm: repro Not tainted 6.18.0-rc6-115d5de2eef3-next-kasan #3 NONE Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 Call Trace: dump_stack_lvl+0x51/0x60 print_report+0xcb/0x5c0 kasan_report+0xb4/0xe0 kvm_gmem_release+0x362/0x400 [kvm] __fput+0x2fa/0x9d0 task_work_run+0x12c/0x200 do_exit+0x6ae/0x2100 do_group_exit+0xa8/0x230 __x64_sys_exit_group+0x3a/0x50 x64_sys_call+0x737/0x740 do_syscall_64+0x5b/0x900 entry_SYSCALL_64_after_hwframe+0x4b/0x53 RIP: 0033:0x7f581f2eac31 Allocated by task 745 on cpu 6 at 9.746971s: kasan_save_stack+0x20/0x40 kasan_save_track+0x13/0x50 __kasan_kmalloc+0x77/0x90 kvm_set_memory_region.part.0+0x652/0x1110 [kvm] kvm_vm_ioctl+0x14b0/0x3290 [kvm] __x64_sys_ioctl+0x129/0x1a0 do_syscall_64+0x5b/0x900 entry_SYSCALL_64_after_hwframe+0x4b/0x53 Freed by task 745 on cpu 6 at 9.747467s: kasan_save_stack+0x20/0x40 kasan_save_track+0x13/0x50 __kasan_save_free_info+0x37/0x50 __kasan_slab_free+0x3b/0x60 kfree+0xf5/0x440 kvm_set_memslot+0x3c2/0x1160 [kvm] kvm_set_memory_region.part.0+0x86a/0x1110 [kvm] kvm_vm_ioctl+0x14b0/0x3290 [kvm] __x64_sys_ioctl+0x129/0x1a0 do_syscall_64+0x5b/0x900 entry_SYSCALL_64_after_hwframe+0x4b/0x53

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

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5: fw_tracer, Validate format string parametersAdd validation for format string parameters in the firmware tracer toprevent potential security vulnerabilities and crashes from malformedformat strings received from firmware.The firmware tracer receives format strings from the device firmware anduses them to format trace messages. Without proper validation, badfirmware could provide format strings with invalid format specifiers(e.g., %s, %p, %n) that could lead to crashes, or other undefinedbehavior.Add mlx5_tracer_validate_params() to validate that all format specifiersin trace strings are limited to safe integer/hex formats (%x, %d, %i,%u, %llx, %lx, etc.). Reject strings containing other format types thatcould be used to access arbitrary memory or cause crashes.Invalid format strings are added to the trace output for visibility with"BAD_FORMAT: " prefix.

This causes a deadlock if the server triggers reclaim whileservicing the readahead request and reclaim attempts to evict the inodeof the file being read ahead.

Description: In the Linux kernel, the following vulnerability has been resolved:ublk: fix deadlock when reading partition tableWhen one process(such as udev) opens ublk block device (e.g., to readthe partition table via bdev_open()), a deadlock[1] can occur:1. bdev_open() grabs disk->open_mutex2. The process issues read I/O to ublk backend to read partition table3. In __ublk_complete_rq(), blk_update_request() or blk_mq_end_request() runs bio->bi_end_io() callbacks4. If this triggers fput() on file descriptor of ublk block device, the work may be deferred to current task's task work (see fput() implementation)5. This eventually calls blkdev_release() from the same context6. blkdev_release() tries to grab disk->open_mutex again7. Deadlock: same task waiting for a mutex it already holdsThe fix is to run blk_update_request() and blk_mq_end_request() with bottomhalves disabled. This forces blkdev_release() to run in kernel work-queuecontext instead of current task work context, and allows ublk server to makeforward progress, and avoids the deadlock.[axboe: rewrite comment in ublk]

However, kinfo->num_tqps is set tomin(new_tqps, hdev->num_tqps); Therefore, kinfo->num_tqps may be smallerthan hdev->num_tqps, which causes some hdev->htqp[i] to remainuninitialized in hclgevf_knic_setup().Thus, this patch allocates hdev->htqp and kinfo->tqp using hdev->num_tqps,ensuring that the lengths of hdev->htqp and kinfo->tqp are consistentand that all elements are properly initialized.

CVE-2025-71069 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:f2fs: invalidate dentry cache on failed whiteout creationF2FS can mount filesystems with corrupted directory depth values thatget runtime-clamped to MAX_DIR_HASH_DEPTH. When RENAME_WHITEOUToperations are performed on such directories, f2fs_rename performsdirectory modifications (updating target entry and deleting sourceentry) before attempting to add the whiteout entry via f2fs_add_link.If f2fs_add_link fails due to the corrupted directory structure, thefunction returns an error to VFS, but the partial directorymodifications have already been committed to disk. VFS assumes theentire rename operation failed and does not update the dentry cache,leaving stale mappings.In the error path, VFS does not call d_move() to update the dentrycache. This results in new_dentry still pointing to the old inode(new_inode) which has already had its i_nlink decremented to zero.The stale cache causes subsequent operations to incorrectly referencethe freed inode.This causes subsequent operations to use cached dentry information thatno longer matches the on-disk state. When a second rename targets thesame entry, VFS attempts to decrement i_nlink on the stale inode, whichmay already have i_nlink=0, triggering a WARNING in drop_nlink().Example sequence:1. First rename (RENAME_WHITEOUT): file2 -> file1 - f2fs updates file1 entry on disk (points to inode 8) - f2fs deletes file2 entry on disk - f2fs_add_link(whiteout) fails (corrupted directory) - Returns error to VFS - VFS does not call d_move() due to error - VFS cache still has: file1 -> inode 7 (stale!) - inode 7 has i_nlink=0 (already decremented)2. Second rename: file3 -> file1 - VFS uses stale cache: file1 -> inode 7 - Tries to drop_nlink on inode 7 (i_nlink already 0) - WARNING in drop_nlink()Fix this by explicitly invalidating old_dentry and new_dentry whenf2fs_add_link fails during whiteout creation. This forces VFS torefresh from disk on subsequent operations, ensuring cache consistencyeven when the rename partially succeeds.Reproducer:1. Mount F2FS image with corrupted i_current_depth2. renameat2(file2, file1, RENAME_WHITEOUT)3. renameat2(file3, file1, 0)4. System triggers WARNING in drop_nlink()

CVE-2025-71072 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:shmem: fix recovery on rename failuresmaple_tree insertions can fail if we are seriously short on memory;simple_offset_rename() does not recover well if it runs into that.The same goes for simple_offset_rename_exchange().Moreover, shmem_whiteout() expects that if it succeeds, the caller willprogress to d_move(), i.e. that shmem_rename2() won't fail past thesuccessful call of shmem_whiteout().Not hard to fix, fortunately - mtree_store() can't fail if the index weare trying to store into is already present in the tree as a singleton.For simple_offset_rename_exchange() that's enough - we just need to becareful about the order of operations.For simple_offset_rename() solution is to preinsert the target into thetree for new_dir; the rest can be done without any potentially failingoperations.That preinsertion has to be done in shmem_rename2() rather than insimple_offset_rename() itself - otherwise we'd need to deal with thepossibility of failure after successful shmem_whiteout().

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

Actually,slab system will only create one slab cache core structure which hasslab name of "f2fs_xattr_entry-7:3", and two slab caches share the samestructure and cache address.So, if we destroy f2fs_xattr_entry-7:3 cache w/ cache address, it willdecrease reference count of slab cache, rather than release slab cacheentirely, since there is one more user has referenced the cache.Then, if we try to create slab cache w/ name "f2fs_xattr_entry-7:3" again,slab system will find that there is existed cache which has the same nameand trigger the warning.Let's changes to use global inline_xattr_slab instead of per-sb slab cachefor fixing.

Note that this is the only fallback critical section thatcould potentially send packets and hit the double-lock.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:LoongArch: BPF: Sign extend kfunc call argumentsThe kfunc calls are native calls so they should follow LoongArch callingconventions. Sign extend its arguments properly to avoid kernel panic.This is done by adding a new emit_abi_ext() helper. The emit_abi_ext()helper performs extension in place meaning a value already store in thetarget register (Note: this is different from the existing sign_extend()helper and thus we can't reuse it).

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

CVE-2025-71161 Severity: Moderate CVSS3 score: 5.5

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

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

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

CVE-2026-22979 Severity: Moderate CVSS3 score: 5.5

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

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

CVE-2026-22981 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:idpf: detach and close netdevs while handling a resetProtect the reset path from callbacks by setting the netdevs to detachedstate and close any netdevs in UP state until the reset handling hascompleted. During a reset, the driver will de-allocate resources for thevport, and there is no guarantee that those will recover, which is why theexisting vport_ctrl_lock does not provide sufficient protection.idpf_detach_and_close() is called right before reset handling. If thereset handling succeeds, the netdevs state is recovered via call toidpf_attach_and_open(). If the reset handling fails the netdevs remaindown. The detach/down calls are protected with RTNL lock to avoid racingwith callbacks. On the recovery side the attach can be done withoutholding the RTNL lock as there are no callbacks expected at that point,due to detach/close always being done first in that flow.The previous logic restoring the netdevs state based on theIDPF_VPORT_UP_REQUESTED flag in the init task is not needed anymore, hencethe removal of idpf_set_vport_state(). The IDPF_VPORT_UP_REQUESTED isstill being used to restore the state of the netdevs following the reset,but has no use outside of the reset handling flow.idpf_init_hard_reset() is converted to void, since it was used as such andthere is no error handling being done based on its return value.Before this change, invoking hard and soft resets simultaneously willcause the driver to lose the vport state:ip -br a UPecho 1 > /sys/class/net/ens801f0/device/reset& \ethtool -L ens801f0 combined 8ip -br a DOWNip link set upip -br a DOWNAlso in case of a failure in the reset path, the netdev is leftexposed to external callbacks, while vport resources are notinitialized, leading to a crash on subsequent ifup/down:[408471.398966] idpf 0000:83:00.0: HW reset detected[408471.411744] idpf 0000:83:00.0: Device HW Reset initiated[408472.277901] idpf 0000:83:00.0: The driver was unable to contact the device's firmware.

CVE-2026-22985 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:idpf: Fix RSS LUT NULL pointer crash on early ethtool operationsThe RSS LUT is not initialized until the interface comes up, causingthe following NULL pointer crash when ethtool operations like rxhash on/offare performed before the interface is brought up for the first time.Move RSS LUT initialization from ndo_open to vport creation to ensure LUTis always available. This enables RSS configuration via ethtool beforebringing the interface up. Simplify LUT management by maintaining allchanges in the driver's soft copy and programming zeros to the indirectiontable when rxhash is disabled. Defer HW programming until the interfacecomes up if it is down during rxhash and LUT configuration changes.Steps to reproduce:** Load idpf driver; interfaces will be created modprobe idpf** Before bringing the interfaces up, turn rxhash off ethtool -K eth2 rxhash off[89408.371875] BUG: kernel NULL pointer dereference, address: 0000000000000000[89408.371908] #PF: supervisor read access in kernel mode[89408.371924] #PF: error_code(0x0000) - not-present page[89408.371940] PGD 0 P4D 0[89408.371953] Oops: Oops: 0000 [#1] SMP NOPTI[89408.372052] RIP: 0010:memcpy_orig+0x16/0x130[89408.372310] Call Trace:[89408.372317] [89408.372326] ? idpf_set_features+0xfc/0x180 [idpf][89408.372363] __netdev_update_features+0x295/0xde0[89408.372384] ethnl_set_features+0x15e/0x460[89408.372406] genl_family_rcv_msg_doit+0x11f/0x180[89408.372429] genl_rcv_msg+0x1ad/0x2b0[89408.372446] ? __pfx_ethnl_set_features+0x10/0x10[89408.372465] ? __pfx_genl_rcv_msg+0x10/0x10[89408.372482] netlink_rcv_skb+0x58/0x100[89408.372502] genl_rcv+0x2c/0x50[89408.372516] netlink_unicast+0x289/0x3e0[89408.372533] netlink_sendmsg+0x215/0x440[89408.372551] __sys_sendto+0x234/0x240[89408.372571] __x64_sys_sendto+0x28/0x30[89408.372585] x64_sys_call+0x1909/0x1da0[89408.372604] do_syscall_64+0x7a/0xfa0[89408.373140] ? clear_bhb_loop+0x60/0xb0[89408.373647] entry_SYSCALL_64_after_hwframe+0x76/0x7e[89408.378887]

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

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

The reason is to keep the patch simpleand easier to backport to stable kernels.Syzbot repro does not crash the kernel anymore and the selftests runsuccessfully.In the follow up we will make __kernel_read() with IOCB_NOWAIT work fornon-sleepable contexts. In addition, I would like to replace thesecretmem check with a more generic approach and will add fstest for thebuildid code.

Description: In the Linux kernel, the following vulnerability has been resolved:block: zero non-PI portion of auto integrity bufferThe auto-generated integrity buffer for writes needs to be fullyinitialized before being passed to the underlying block device,otherwise the uninitialized memory can be read back by userspace oranyone with physical access to the storage device. If protectioninformation is generated, that portion of the integrity buffer isalready initialized. The integrity data is also zeroed if PI generationis disabled via sysfs or the PI tuple size is 0. However, this missesthe case where PI is generated and the PI tuple size is nonzero, but themetadata size is larger than the PI tuple. In this case, the remainder("opaque") of the metadata is left uninitialized.Generalize the BLK_INTEGRITY_CSUM_NONE check to cover any case when themetadata is larger than just the PI tuple.

Description: In the Linux kernel, the following vulnerability has been resolved:hwmon: (ftsteutates) Fix TOCTOU race in fts_read()In the fts_read() function, when handling hwmon_pwm_auto_channels_temp,the code accesses the shared variable data->fan_source[channel] twicewithout holding any locks. It is first checked againstFTS_FAN_SOURCE_INVALID, and if the check passes, it is read againwhen used as an argument to the BIT() macro.This creates a Time-of-Check to Time-of-Use (TOCTOU) race condition.Another thread executing fts_update_device() can modify the value ofdata->fan_source[channel] between the check and its use. If the valueis changed to FTS_FAN_SOURCE_INVALID (0xff) during this window, theBIT() macro will be called with a large shift value (BIT(255)).A bit shift by a value greater than or equal to the type width isundefined behavior and can lead to a crash or incorrect values beingreturned to userspace.Fix this by reading data->fan_source[channel] into a local variableonce, eliminating the race condition. Additionally, add a bounds checkto ensure the value is less than BITS_PER_LONG before passing it tothe BIT() macro, making the code more robust against undefined behavior.This possible bug was found by an experimental static analysis tooldeveloped by our team.

Currently,it relies on checking the PTE value to ensure that the moved folio stillbelongs to the src swap entry and that no new folio has been added to theswap cache, which turns out to be unreliable.While working and reviewing the swap table series with Barry, followingexisting races are observed and reproduced [1]:In the example below, move_pages_pte is moving src_pte to dst_pte, wheresrc_pte is a swap entry PTE holding swap entry S1, and S1 is not in theswap cache:CPU1 CPU2userfaultfd_move move_pages_pte() entry = pte_to_swp_entry(orig_src_pte); // Here it got entry = S1 ... < interrupted> ... // folio A is a new allocated folio // and get installed into src_pte // src_pte now points to folio A, S1 // has swap count == 0, it can be freed // by folio_swap_swap or swap // allocator's reclaim. // folio B is a folio in another VMA. // S1 is freed, folio B can use it // for swap out with no problem. ... folio = filemap_get_folio(S1) // Got folio B here !!! ... < interrupted again> ... // Now S1 is free to be used again. // Now src_pte is a swap entry PTE // holding S1 again. folio_trylock(folio) move_swap_pte double_pt_lock is_pte_pages_stable // Check passed because src_pte == S1 folio_move_anon_rmap(...) // Moved invalid folio B here !!!The race window is very short and requires multiple collisions of multiplerare events, so it's very unlikely to happen, but with a deliberatelyconstructed reproducer and increased time window, it can be reproducedeasily.This can be fixed by checking if the folio returned by filemap is thevalid swap cache folio after acquiring the folio lock.Another similar race is possible: filemap_get_folio may return NULL, butfolio (A) could be swapped in and then swapped out again using the sameswap entry after the lookup. In such a case, folio (A) may remain in theswap cache, so it must be moved too:CPU1 CPU2userfaultfd_move move_pages_pte() entry = pte_to_swp_entry(orig_src_pte); // Here it got entry = S1, and S1 is not in swap cache folio = filemap_get---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:fs/nfs/read: fix double-unlock bug in nfs_return_empty_folio()Sometimes, when a file was read while it was being truncated byanother NFS client, the kernel could deadlock because folio_unlock()was called twice, and the second call would XOR back the `PG_locked`flag.Most of the time (depending on the timing of the truncation), nobodynotices the problem because folio_unlock() gets called three times,which flips `PG_locked` back off: 1. vfs_read, nfs_read_folio, ... nfs_read_add_folio, nfs_return_empty_folio 2. vfs_read, nfs_read_folio, ... netfs_read_collection, netfs_unlock_abandoned_read_pages 3. vfs_read, ... nfs_do_read_folio, nfs_read_add_folio, nfs_return_empty_folioThe problem is that nfs_read_add_folio() is not supposed to unlock thefolio if fscache is enabled, and a nfs_netfs_folio_unlock() check ismissing in nfs_return_empty_folio().Rarely this leads to a warning in netfs_read_collection(): ------------[ cut here ]------------ R=0000031c: folio 10 is not locked WARNING: CPU: 0 PID: 29 at fs/netfs/read_collect.c:133 netfs_read_collection+0x7c0/0xf00 [...] Workqueue: events_unbound netfs_read_collection_worker RIP: 0010:netfs_read_collection+0x7c0/0xf00 [...] Call Trace: netfs_read_collection_worker+0x67/0x80 process_one_work+0x12e/0x2c0 worker_thread+0x295/0x3a0Most of the time, however, processes just get stuck forever infolio_wait_bit_common(), waiting for `PG_locked` to disappear, whichnever happens because nobody is really holding the folio lock.

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

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

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

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

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

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

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

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

CVE-2025-66199 Severity: Moderate CVSS3 score: 5.3

Description: Issue summary: A TLS 1.3 connection using certificate compression can beforced to allocate a large buffer before decompression without checkingagainst the configured certificate size limit.Impact summary: An attacker can cause per-connection memory allocations ofup to approximately 22 MiB and extra CPU work, potentially leading toservice degradation or resource exhaustion (Denial of Service).In affected configurations, the peer-supplied uncompressed certificatelength from a CompressedCertificate message is used to grow a heap bufferprior to decompression. This length is not bounded by the max_cert_listsetting, which otherwise constrains certificate message sizes. An attackercan exploit this to cause large per-connection allocations followed byhandshake failure. No memory corruption or information disclosure occurs.This issue only affects builds where TLS 1.3 certificate compression iscompiled in (i.e., not OPENSSL_NO_COMP_ALG) and at least one compressionalgorithm (brotli, zlib, or zstd) is available, and where the compressionextension is negotiated. Both clients receiving a server CompressedCertificateand servers in mutual TLS scenarios receiving a client CompressedCertificateare affected. Servers that do not request client certificates are notvulnerable to client-initiated attacks.Users can mitigate this issue by setting SSL_OP_NO_RX_CERTIFICATE_COMPRESSIONto disable receiving compressed certificates.The FIPS modules in 3.6, 3.5, 3.4 and 3.3 are not affected by this issue,as the TLS implementation is outside the OpenSSL FIPS module boundary.OpenSSL 3.6, 3.5, 3.4 and 3.3 are vulnerable to this issue.OpenSSL 3.0, 1.1.1 and 1.0.2 are not affected by this issue.

CVE-2025-66418 Severity: Moderate CVSS3 score: 5.3

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

CVE-2025-66471 Severity: Moderate CVSS3 score: 5.3

Description: urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.0 and prior to 2.6.0, the Streaming API improperly handles highly compressed data. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. When streaming a compressed response, urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header (e.g., gzip, deflate, br, or zstd). The library must read compressed data from the network and decompress it until the requested chunk size is met. Any resulting decompressed data that exceeds the requested amount is held in an internal buffer for the next read operation. The decompression logic could cause urllib3 to fully decode a small amount of highly compressed data in a single operation. This can result in excessive resource consumption (high CPU usage and massive memory allocation for the decompressed data.

Versions 3.13.2 and below enable an attacker to ascertain the existence of absolute path components through the path normalization logic for static files meant to prevent path traversal.

CVE-2025-69418 Severity: Moderate CVSS3 score: 5.3

Description: Issue summary: When using the low-level OCB API directly with AES-NI or
other hardware-accelerated code paths, inputs whose length is not a multiple
of 16 bytes can leave the final partial block unencrypted and unauthenticated.

Impact summary: The trailing 1-15 bytes of a message may be exposed in
cleartext on encryption and are not covered by the authentication tag,
allowing an attacker to read or tamper with those bytes without detection.

The low-level OCB encrypt and decrypt routines in the hardware-accelerated
stream path process full 16-byte blocks but do not advance the input/output
pointers. The subsequent tail-handling code then operates on the original
base pointers, effectively reprocessing the beginning of the buffer while
leaving the actual trailing bytes unprocessed. The authentication checksum
also excludes the true tail bytes.

However, typical OpenSSL consumers using EVP are not affected because the
higher-level EVP and provider OCB implementations split inputs so that full
blocks and trailing partial blocks are processed in separate calls, avoiding
the problematic code path. Additionally, TLS does not use OCB ciphersuites.
The vulnerability only affects applications that call the low-level
CRYPTO_ocb128_encrypt() or CRYPTO_ocb128_decrypt() functions directly with
non-block-aligned lengths in a single call on hardware-accelerated builds.
For these reasons the issue was assessed as Low severity.

The FIPS modules in 3.6, 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected
by this issue, as OCB mode is not a FIPS-approved algorithm.

OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0 and 1.1.1 are vulnerable to this issue.

Description: Issue summary: A type confusion vulnerability exists in the TimeStamp Responseverification code where an ASN1_TYPE union member is accessed without firstvalidating the type, causing an invalid or NULL pointer dereference whenprocessing a malformed TimeStamp Response file.Impact summary: An application calling TS_RESP_verify_response() with amalformed TimeStamp Response can be caused to dereference an invalid orNULL pointer when reading, resulting in a Denial of Service.The functions ossl_ess_get_signing_cert() and ossl_ess_get_signing_cert_v2()access the signing cert attribute value without validating its type.When the type is not V_ASN1_SEQUENCE, this results in accessing invalid memorythrough the ASN1_TYPE union, causing a crash.Exploiting this vulnerability requires an attacker to provide a malformedTimeStamp Response to an application that verifies timestamp responses.

CVE-2025-9231 Severity: Moderate CVSS3 score: 5.3

Description: Issue summary: A timing side-channel which could potentially allow remoterecovery of the private key exists in the SM2 algorithm implementation on 64 bitARM platforms.Impact summary: A timing side-channel in SM2 signature computations on 64 bitARM platforms could allow recovering the private key by an attacker..While remote key recovery over a network was not attempted by the reporter,timing measurements revealed a timing signal which may allow such an attack.OpenSSL does not directly support certificates with SM2 keys in TLS, and sothis CVE is not relevant in most TLS contexts. However, given that it ispossible to add support for such certificates via a custom provider, coupledwith the fact that in such a custom provider context the private key may berecoverable via remote timing measurements, we consider this to be a Moderateseverity issue.The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by thisissue, as SM2 is not an approved algorithm.

Description: HarfBuzz is a text shaping engine. Prior to version 12.3.0, a null pointer dereference vulnerability exists in the SubtableUnicodesCache::create function located in src/hb-ot-cmap-table.hh. The function fails to check if hb_malloc returns NULL before using placement new to construct an object at the returned pointer address. When hb_malloc fails to allocate memory (which can occur in low-memory conditions or when using custom allocators that simulate allocation failures), it returns NULL. The code then attempts to call the constructor on this null pointer using placement new syntax, resulting in undefined behavior and a Segmentation Fault. This issue has been patched in version 12.3.0.

The code isdesigned to work this way without disabling IRQs and occasionally fail thetrylock with a fallback. However, the SMP=n spinlock implementationassumes spin_trylock() will always succeed, and thus it's normally ano-op. Here the enabled lock debugging catches the problem, but otherwiseit could cause a corruption of the pcp structure.The problem has been introduced by commit 574907741599 ("mm/page_alloc:leave IRQs enabled for per-cpu page allocations"). The pcp locking schemerecognizes the need for disabling IRQs to prevent nesting spin_trylock()sections on SMP=n, but the need to prevent the nesting in spin_lock() hasnot been recognized. Fix it by introducing local wrappers that change thespin_lock() to spin_lock_iqsave() with SMP=n and use them in all placesthat do spin_lock(&pcp->lock).[vbabka@suse.cz: add pcp_ prefix to the spin_lock_irqsave wrappers, per Steven]

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

CVE-2025-38140 Severity: Moderate CVSS3 score: 5.1

Description: In the Linux kernel, the following vulnerability has been resolved:dm: limit swapping tables for devices with zone write plugsdm_revalidate_zones() only allowed new or previously unzoned devices tocall blk_revalidate_disk_zones(). If the device was already zoned,disk->nr_zones would always equal md->nr_zones, so dm_revalidate_zones()returned without doing any work. This would make the zoned settings forthe device not match the new table. If the device had zone write plugresources, it could run into errors like bdev_zone_is_seq() readinginvalid memory because disk->conv_zones_bitmap was the wrong size.If the device doesn't have any zone write plug resources, callingblk_revalidate_disk_zones() will always correctly update device. Ifblk_revalidate_disk_zones() fails, it can still overwrite or clear thecurrent disk->nr_zones value. In this case, DM must restore the previousvalue of disk->nr_zones, so that the zoned settings will continue tomatch the previous value that it fell back to.If the device already has zone write plug resources,blk_revalidate_disk_zones() will not correctly update them, if it iscalled for arbitrary zoned device changes. Since there is not much needfor this ability, the easiest solution is to disallow any table reloadsthat change the zoned settings, for devices that already have zone plugresources. Specifically, if a device already has zone plug resourcesallocated, it can only switch to another zoned table that also emulateszone append. Also, it cannot change the device size or the zone size. Adevice can switch to an error target.

CVE-2025-38658 Severity: Moderate CVSS3 score: 5.1

Description: In the Linux kernel, the following vulnerability has been resolved:nvmet: pci-epf: Do not complete commands twice if nvmet_req_init() failsHave nvmet_req_init() and req->execute() complete failed commands.Description of the problem:nvmet_req_init() calls __nvmet_req_complete() internally upon failure,e.g., unsupported opcode, which calls the "queue_response" callback,this results in nvmet_pci_epf_queue_response() being called, which willcall nvmet_pci_epf_complete_iod() if data_len is 0 or if dma_dir isdifferent from DMA_TO_DEVICE. This results in a double completion asnvmet_pci_epf_exec_iod_work() also calls nvmet_pci_epf_complete_iod()when nvmet_req_init() fails.Steps to reproduce:On the host send a command with an unsupported opcode with nvme-cli,For example the admin command "security receive"$ sudo nvme security-recv /dev/nvme0n1 -n1 -x4096This triggers a double completion as nvmet_req_init() fails andnvmet_pci_epf_queue_response() is called, here iod->dma_dir is stillin the default state of "DMA_NONE" as set by default innvmet_pci_epf_alloc_iod(), so nvmet_pci_epf_complete_iod() is called.Because nvmet_req_init() failed nvmet_pci_epf_complete_iod() is alsocalled in nvmet_pci_epf_exec_iod_work() leading to a double completion.This not only sends two completions to the host but also corrupts thestate of the PCI NVMe target leading to kernel oops.This patch lets nvmet_req_init() and req->execute() complete all failedcommands, and removes the double completion case innvmet_pci_epf_exec_iod_work() therefore fixing the edge cases wheredouble completions occurred.

CVE-2024-50145 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:octeon_ep: Add SKB allocation failures handling in __octep_oq_process_rx()build_skb() returns NULL in case of a memory allocation failure so handleit inside __octep_oq_process_rx() to avoid NULL pointer dereference.__octep_oq_process_rx() is called during NAPI polling by the driver. Ifskb allocation fails, keep on pulling packets out of the Rx DMA queue: weshouldn't break the polling immediately and thus falsely indicate to theoctep_napi_poll() that the Rx pressure is going down. As there is noassociated skb in this case, don't process the packets and don't push themup the network stack - they are skipped.Helper function is implemented to unmmap/flush all the fragment buffersused by the dropped packet. 'alloc_failures' counter is incremented tomark the skb allocation error in driver statistics.Found by Linux Verification Center (linuxtesting.org) with SVACE.

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

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

CVE-2025-37856 Severity: Moderate CVSS3 score: 4.7

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:atm: Release atm_dev_mutex after removing procfs in atm_dev_deregister().syzbot reported a warning below during atm_dev_register(). [0]Before creating a new device and procfs/sysfs for it, atm_dev_register()looks up a duplicated device by __atm_dev_lookup(). These operations aredone under atm_dev_mutex.However, when removing a device in atm_dev_deregister(), it releases themutex just after removing the device from the list that __atm_dev_lookup()iterates over.So, there will be a small race window where the device does not exist onthe device list but procfs/sysfs are still not removed, triggering thesplat.Let's hold the mutex until procfs/sysfs are removed inatm_dev_deregister().[0]:proc_dir_entry 'atm/atmtcp:0' already registeredWARNING: CPU: 0 PID: 5919 at fs/proc/generic.c:377 proc_register+0x455/0x5f0 fs/proc/generic.c:377Modules linked in:CPU: 0 UID: 0 PID: 5919 Comm: syz-executor284 Not tainted 6.16.0-rc2-syzkaller-00047-g52da431bf03b #0 PREEMPT(full)Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 05/07/2025RIP: 0010:proc_register+0x455/0x5f0 fs/proc/generic.c:377Code: 48 89 f9 48 c1 e9 03 80 3c 01 00 0f 85 a2 01 00 00 48 8b 44 24 10 48 c7 c7 20 c0 c2 8b 48 8b b0 d8 00 00 00 e8 0c 02 1c ff 90 <0f> 0b 90 90 48 c7 c7 80 f2 82 8e e8 0b de 23 09 48 8b 4c 24 28 48RSP: 0018:ffffc9000466fa30 EFLAGS: 00010282RAX: 0000000000000000 RBX: 0000000000000000 RCX: ffffffff817ae248RDX: ffff888026280000 RSI: ffffffff817ae255 RDI: 0000000000000001RBP: ffff8880232bed48 R08: 0000000000000001 R09: 0000000000000000R10: 0000000000000000 R11: 0000000000000001 R12: ffff888076ed2140R13: dffffc0000000000 R14: ffff888078a61340 R15: ffffed100edda444FS: 00007f38b3b0c6c0(0000) GS:ffff888124753000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007f38b3bdf953 CR3: 0000000076d58000 CR4: 00000000003526f0DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400Call Trace: proc_create_data+0xbe/0x110 fs/proc/generic.c:585 atm_proc_dev_register+0x112/0x1e0 net/atm/proc.c:361 atm_dev_register+0x46d/0x890 net/atm/resources.c:113 atmtcp_create+0x77/0x210 drivers/atm/atmtcp.c:369 atmtcp_attach drivers/atm/atmtcp.c:403 [inline] atmtcp_ioctl+0x2f9/0xd60 drivers/atm/atmtcp.c:464 do_vcc_ioctl+0x12c/0x930 net/atm/ioctl.c:159 sock_do_ioctl+0x115/0x280 net/socket.c:1190 sock_ioctl+0x227/0x6b0 net/socket.c:1311 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:907 [inline] __se_sys_ioctl fs/ioctl.c:893 [inline] __x64_sys_ioctl+0x18b/0x210 fs/ioctl.c:893 do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline] do_syscall_64+0xcd/0x4c0 arch/x86/entry/syscall_64.c:94 entry_SYSCALL_64_after_hwframe+0x77/0x7fRIP: 0033:0x7f38b3b74459Code: 28 00 00 00 75 05 48 83 c4 28 c3 e8 51 18 00 00 90 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b0 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007f38b3b0c198 EFLAGS: 00000246 ORIG_RAX: 0000000000000010RAX: ffffffffffffffda RBX: 00007f38b3bfe318 RCX: 00007f38b3b74459RDX: 0000000000000000 RSI: 0000000000006180 RDI: 0000000000000005RBP: 00007f38b3bfe310 R08: 65732f636f72702f R09: 65732f636f72702fR10: 65732f636f72702f R11: 0000000000000246 R12: 00007f38b3bcb0acR13: 00007f38b3b0c1a0 R14: 0000200000000200 R15: 00007f38b3bcb03b

Consequently, ifthe device is removed while aes_battery_work is still pending, then hardcrashes or "Oops: general protection fault..." are experienced whenwacom_aes_battery_handler() is finally called. E.g., this happens withbuilt-in USB devices after resume from hibernate when aes_battery_workwas still pending at the time of hibernation.So, take care to cancel aes_battery_work in wacom_remove().

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: ath12k: fix node corruption in ar->arvifs listIn current WLAN recovery code flow, ath12k_core_halt() only reinitializesthe "arvifs" list head. This will cause the list node immediately followingthe list head to become an invalid list node. Because the prev of that nodestill points to the list head "arvifs", but the next of the list head"arvifs" no longer points to that list node.When a WLAN recovery occurs during the execution of a vif removal, and ithappens before the spin_lock_bh(&ar->data_lock) inath12k_mac_vdev_delete(), list_del() will detect the previously mentionedsituation, thereby triggering a kernel panic.The fix is to remove and reinitialize all vif list nodes from the list head"arvifs" during WLAN halt. The reinitialization is to make the list nodesvalid, ensuring that the list_del() in ath12k_mac_vdev_delete() can executenormally.Call trace:__list_del_entry_valid_or_report+0xd4/0x100 (P)ath12k_mac_remove_link_interface.isra.0+0xf8/0x2e4 [ath12k]ath12k_scan_vdev_clean_work+0x40/0x164 [ath12k]cfg80211_wiphy_work+0xfc/0x100process_one_work+0x164/0x2d0worker_thread+0x254/0x380kthread+0xfc/0x100ret_from_fork+0x10/0x20The change is mostly copied from the ath11k patch:https://lore.kernel.org/all/20250320053145.3445187-1-quic_stonez@quicinc.com/Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1

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

Description: In the Linux kernel, the following vulnerability has been resolved:iavf: get rid of the crit lockGet rid of the crit lock.That frees us from the error prone logic of try_locks.Thanks to netdev_lock() by Jakub it is now easy, and in most cases we wereprotected by it already - replace crit lock by netdev lock when it was notthe case.Lockdep reports that we should cancel the work under crit_lock [splat1],and that was the scheme we have mostly followed since [1] by Slawomir.But when that is done we still got into deadlocks [splat2]. So insteadwe should look at the bigger problem, namely "weird locking/scheduling"of the iavf. The first step to fix that is to remove the crit lock.I will followup with a -next series that simplifies scheduling/tasks.Cancel the work without netdev lock (weird unlock+lock scheme),to fix the [splat2] (which would be totally ugly if we would keptthe crit lock).Extend protected part of iavf_watchdog_task() to include schedulingmore work.Note that the removed comment in iavf_reset_task() was misplaced,it belonged to inside of the removed if condition, so it's gone now.[splat1] - w/o this patch - The deadlock during VF removal: WARNING: possible circular locking dependency detected sh/3825 is trying to acquire lock: ((work_completion)(&(&adapter->watchdog_task)->work)){+.+.}-{0:0}, at: start_flush_work+0x1a1/0x470 but task is already holding lock: (&adapter->crit_lock){+.+.}-{4:4}, at: iavf_remove+0xd1/0x690 [iavf] which lock already depends on the new lock.[splat2] - when cancelling work under crit lock, w/o this series, see [2] for the band aid attempt WARNING: possible circular locking dependency detected sh/3550 is trying to acquire lock: ((wq_completion)iavf){+.+.}-{0:0}, at: touch_wq_lockdep_map+0x26/0x90 but task is already holding lock: (&dev->lock){+.+.}-{4:4}, at: iavf_remove+0xa6/0x6e0 [iavf] which lock already depends on the new lock.[1] fc2e6b3b132a ("iavf: Rework mutexes for better synchronisation")[2] https://github.com/pkitszel/linux/commit/52dddbfc2bb60294083f5711a158a

A similar issue was fixed beforein commit 6694482a70e9 ("drm/msm: Avoid unclocked GMU register access in6xx gpu_busy"): msm_devfreq_init() does call devfreq_suspend_device(), butunlike msm_devfreq_suspend(), it doesn't set the df->suspended flagaccordingly. This means the df->suspended flag does not match the actualdevfreq state after initialization and msm_devfreq_get_dev_status() willend up accessing GMU registers, causing the crash.Fix this by setting df->suspended correctly during initialization.Patchwork: https://patchwork.freedesktop.org/patch/650772/

CVE-2025-38373 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:IB/mlx5: Fix potential deadlock in MR deregistrationThe issue arises when kzalloc() is invoked while holding umem_mutex orany other lock acquired under umem_mutex. This is problematic becausekzalloc() can trigger fs_reclaim_aqcuire(), which may, in turn, invokemmu_notifier_invalidate_range_start(). This function can lead tomlx5_ib_invalidate_range(), which attempts to acquire umem_mutex again,resulting in a deadlock.The problematic flow: CPU0 | CPU1---------------------------------------|------------------------------------------------mlx5_ib_dereg_mr() | -> revoke_mr() | -> mutex_lock(&umem_odp->umem_mutex) | | mlx5_mkey_cache_init() | -> mutex_lock(&dev->cache.rb_lock) | -> mlx5r_cache_create_ent_locked() | -> kzalloc(GFP_KERNEL) | -> fs_reclaim() | -> mmu_notifier_invalidate_range_start() | -> mlx5_ib_invalidate_range() | -> mutex_lock(&umem_odp->umem_mutex) -> cache_ent_find_and_store() | -> mutex_lock(&dev->cache.rb_lock) |Additionally, when kzalloc() is called from withincache_ent_find_and_store(), we encounter the same deadlock due tore-acquisition of umem_mutex.Solve by releasing umem_mutex in dereg_mr() after umr_revoke_mr()and before acquiring rb_lock. This ensures that we don't holdumem_mutex while performing memory allocations that could triggerthe reclaim path.This change prevents the deadlock by ensuring proper lock ordering andavoiding holding locks during memory allocation operations that couldtrigger the reclaim path.The following lockdep warning demonstrates the deadlock: python3/20557 is trying to acquire lock: ffff888387542128 (&umem_odp->umem_mutex){+.+.}-{4:4}, at: mlx5_ib_invalidate_range+0x5b/0x550 [mlx5_ib] but task is already holding lock: ffffffff82f6b840 (mmu_notifier_invalidate_range_start){+.+.}-{0:0}, at: unmap_vmas+0x7b/0x1a0 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #3 (mmu_notifier_invalidate_range_start){+.+.}-{0:0}: fs_reclaim_acquire+0x60/0xd0 mem_cgroup_css_alloc+0x6f/0x9b0 cgroup_init_subsys+0xa4/0x240 cgroup_init+0x1c8/0x510 start_kernel+0x747/0x760 x86_64_start_reservations+0x25/0x30 x86_64_start_kernel+0x73/0x80 common_startup_64+0x129/0x138 -> #2 (fs_reclaim){+.+.}-{0:0}: fs_reclaim_acquire+0x91/0xd0 __kmalloc_cache_noprof+0x4d/0x4c0 mlx5r_cache_create_ent_locked+0x75/0x620 [mlx5_ib] mlx5_mkey_cache_init+0x186/0x360 [mlx5_ib] mlx5_ib_stage_post_ib_reg_umr_init+0x3c/0x60 [mlx5_ib] __mlx5_ib_add+0x4b/0x190 [mlx5_ib] mlx5r_probe+0xd9/0x320 [mlx5_ib] auxiliary_bus_probe+0x42/0x70 really_probe+0xdb/0x360 __driver_probe_device+0x8f/0x130 driver_probe_device+0x1f/0xb0 __driver_attach+0xd4/0x1f0 bus_for_each_dev+0x79/0xd0 bus_add_driver+0xf0/0x200 driver_register+0x6e/0xc0 __auxiliary_driver_register+0x6a/0xc0 do_one_initcall+0x5e/0x390 do_init_module+0x88/0x240 init_module_from_file+0x85/0xc0 idempotent_init_module+0x104/0x300 __x64_sys_finit_module+0x68/0xc0 do_syscall_64+0x6d/0x140 entry_SYSCALL_64_after_hwframe+0x4b/0x53 -> #1 (&dev->cache.rb_lock){+.+.}-{4:4}: __mutex_lock+0x98/0xf10 __mlx5_ib_dereg_mr+0x6f2/0x890 [mlx5_ib] mlx5_ib_dereg_mr+0x21/0x110 [mlx5_ib] ib_dereg_mr_user+0x85/0x1f0 [ib_core] ---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:NFSv4/pNFS: Fix a race to wake on NFS_LAYOUT_DRAINWe found a few different systems hung up in writeback waiting on the samepage lock, and one task waiting on the NFS_LAYOUT_DRAIN bit inpnfs_update_layout(), however the pnfs_layout_hdr's plh_outstanding countwas zero.It seems most likely that this is another race between the waiter and wakersimilar to commit ed0172af5d6f ("SUNRPC: Fix a race to wake a sync task").Fix it up by applying the advised barrier.

If application A's job depends on ascheduled fence from application B's job, and that fence is not properlysignaled during the killing process, application A's dependency cannot becleared.This leads to application A hanging indefinitely while waiting for adependency that will never be resolved. Fix this issue by ensuring thatscheduled fences are properly signaled when an entity is killed, allowingdependent applications to continue execution.

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5e: Fix race between DIM disable and net_dim()There's a race between disabling DIM and NAPI callbacks using the dimpointer on the RQ or SQ.If NAPI checks the DIM state bit and sees it still set, it assumes`rq->dim` or `sq->dim` is valid. But if DIM gets disabled right afterthat check, the pointer might already be set to NULL, leading to a NULLpointer dereference in net_dim().Fix this by calling `synchronize_net()` before freeing the DIM context.This ensures all in-progress NAPI callbacks are finished before thepointer is cleared.Kernel log:BUG: kernel NULL pointer dereference, address: 0000000000000000...RIP: 0010:net_dim+0x23/0x190...Call Trace: ? __die+0x20/0x60 ? page_fault_oops+0x150/0x3e0 ? common_interrupt+0xf/0xa0 ? sysvec_call_function_single+0xb/0x90 ? exc_page_fault+0x74/0x130 ? asm_exc_page_fault+0x22/0x30 ? net_dim+0x23/0x190 ? mlx5e_poll_ico_cq+0x41/0x6f0 [mlx5_core] ? sysvec_apic_timer_interrupt+0xb/0x90 mlx5e_handle_rx_dim+0x92/0xd0 [mlx5_core] mlx5e_napi_poll+0x2cd/0xac0 [mlx5_core] ? mlx5e_poll_ico_cq+0xe5/0x6f0 [mlx5_core] busy_poll_stop+0xa2/0x200 ? mlx5e_napi_poll+0x1d9/0xac0 [mlx5_core] ? mlx5e_trigger_irq+0x130/0x130 [mlx5_core] __napi_busy_loop+0x345/0x3b0 ? sysvec_call_function_single+0xb/0x90 ? asm_sysvec_call_function_single+0x16/0x20 ? sysvec_apic_timer_interrupt+0xb/0x90 ? pcpu_free_area+0x1e4/0x2e0 napi_busy_loop+0x11/0x20 xsk_recvmsg+0x10c/0x130 sock_recvmsg+0x44/0x70 __sys_recvfrom+0xbc/0x130 ? __schedule+0x398/0x890 __x64_sys_recvfrom+0x20/0x30 do_syscall_64+0x4c/0x100 entry_SYSCALL_64_after_hwframe+0x4b/0x53...---[ end trace 0000000000000000 ]---...---[ end Kernel panic - not syncing: Fatal exception in interrupt ]---

If we ignorect->status and pretend its 0, the entry matches those that are newlyallocated but not yet inserted into the hash: - ct hlist pointers are overloaded and store/cache the raw tuple hash - ct->timeout matches the relative time expected for a new udp flow rather than the absolute 'jiffies' value.If it were not for the presence of IPS_CONFIRMED,__nf_conntrack_find_get() would have skipped the entry.Theory is that we did hit following race:cpu x cpu y cpu z found entry E found entry E E is expired nf_ct_delete() return E to rcu slab init_conntrack E is re-inited, ct->status set to 0 reply tuplehash hnnode.pprev stores hash value.cpu y found E right before it was deleted on cpu x.E is now re-inited on cpu z. cpu y was preempted beforechecking for expiry and/or confirm bit. ->refcnt set to 1 E now owned by skb ->timeout set to 30000If cpu y were to resume now, it would observe E asexpired but would skip E due to missing CONFIRMED bit. nf_conntrack_confirm gets called sets: ct->status |= CONFIRMED This is wrong: E is not yet added to hashtable.cpu y resumes, it observes E as expired but CONFIRMED: nf_ct_expired() -> yes (ct->timeout is 30s) confirmed bit set.cpu y will try to delete E from the hashtable: nf_ct_delete() -> set DYING bit __nf_ct_delete_from_listsEven this scenario doesn't guarantee a crash:cpu z still holds the table bucket lock(s) so y blocks: wait for spinlock held by z CONFIRMED is set but there is no guarantee ct will be added to hash: "chaintoolong" or "clash resolution" logic both skip the insert step. reply hnnode.pprev still stores the hash value. unlocks spinlock return NF_DROP In case CPU z does insert the entry into the hashtable, cpu y will unlinkE again right away but no crash occurs.Without 'cpu y' race, 'garbage' hlist is of no consequence:ct refcnt remains at 1, eventually skb will be free'd and E getsdestroyed via: nf_conntrack_put -> nf_conntrack_destroy -> nf_ct_destroy.To resolve this, move the IPS_CONFIRMED assignment after the tableinsertion but before the unlock.Pablo points out that the confirm-bit-store could be reordered to happenbefore hlist add resp. the timeout fixup, so switch to set_bit andbefore_atomic memory barrier to prevent this.It doesn't matter if other CPUs can observe a newly inserted entry rightbefore the CONFIRMED bit was set:Such event cannot be distinguished from above "E is the old incarnation"case: the entry will be skipped.Also change nf_ct_should_gc() to first check the confirmed bit.The gc sequence is: 1. Check if entry has expired, if not skip to next entry 2. Obtain a reference to the expired entry. 3. Call nf_ct_should_gc() to double-check step 1.nf_ct_should_gc() is thus called only for entries that already failed anexpiry check. After this patch, once the confirmed bit check pas---truncated---

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

CVE-2025-38632 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:pinmux: fix race causing mux_owner NULL with active mux_usecountcommit 5a3e85c3c397 ("pinmux: Use sequential access to accessdesc->pinmux data") tried to address the issue when two client of thesame gpio calls pinctrl_select_state() for the same functionality, wasresulting in NULL pointer issue while accessing desc->mux_owner.However, issue was not completely fixed due to the way it was handledand it can still result in the same NULL pointer.The issue occurs due to the following interleaving: cpu0 (process A) cpu1 (process B) pin_request() { pin_free() { mutex_lock() desc->mux_usecount--; //becomes 0 .. mutex_unlock() mutex_lock(desc->mux) desc->mux_usecount++; // becomes 1 desc->mux_owner = owner; mutex_unlock(desc->mux) mutex_lock(desc->mux) desc->mux_owner = NULL; mutex_unlock(desc->mux)This sequence leads to a state where the pin appears to be in use(`mux_usecount == 1`) but has no owner (`mux_owner == NULL`), which cancause NULL pointer on next pin_request on the same pin.Ensure that updates to mux_usecount and mux_owner are performedatomically under the same lock. Only clear mux_owner when mux_usecountreaches zero and no new owner has been assigned.

CVE-2025-39792 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:dm: Always split write BIOs to zoned device limitsAny zoned DM target that requires zone append emulation will use theblock layer zone write plugging. In such case, DM target drivers mustnot split BIOs using dm_accept_partial_bio() as doing so can potentiallylead to deadlocks with queue freeze operations. Regular write operationsused to emulate zone append operations also cannot be split by thetarget driver as that would result in an invalid writen sector valuereturn using the BIO sector.In order for zoned DM target drivers to avoid such incorrect BIOsplitting, we must ensure that large BIOs are split before being passedto the map() function of the target, thus guaranteeing that thelimits for the mapped device are not exceeded.dm-crypt and dm-flakey are the only target drivers supporting zoneddevices and using dm_accept_partial_bio().In the case of dm-crypt, this function is used to split BIOs to theinternal max_write_size limit (which will be suppressed in a differentpatch). However, since crypt_alloc_buffer() uses a bioset allowing onlyup to BIO_MAX_VECS (256) vectors in a BIO. The dm-crypt devicemax_segments limit, which is not set and so default to BLK_MAX_SEGMENTS(128), must thus be respected and write BIOs split accordingly.In the case of dm-flakey, since zone append emulation is not required,the block layer zone write plugging is not used and no splitting of BIOsrequired.Modify the function dm_zone_bio_needs_split() to use the block layerhelper function bio_needs_zone_write_plugging() to force a call tobio_split_to_limits() in dm_split_and_process_bio(). This allows DMtarget drivers to avoid using dm_accept_partial_bio() for writeoperations on zoned DM devices.

Skipping the table-dependent suspend logic in this caseis safe and avoids NULL pointer dereferences.

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

When the number of attached queuesdrops to 1 blk_mq_del_queue_tag_set() need to mark both the tagset andthe remaining queues as unshared.Both functions need to freeze current queues in tagset before setting onunsetting BLK_MQ_F_TAG_QUEUE_SHARED flag. While doing so, both functionshold set->tag_list_lock mutex, which makes sense as we do not wantqueues to be added or deleted in the process. This used to work fineuntil commit 98d81f0df70c ("nvme: use blk_mq_[un]quiesce_tagset")made the nvme driver quiesce tagset instead of quiscing individualqueues. blk_mq_quiesce_tagset() does the job and quiesce the queues inset->tag_list while holding set->tag_list_lock also.This results in deadlock between two threads with these stacktraces: __schedule+0x47c/0xbb0 ? timerqueue_add+0x66/0xb0 schedule+0x1c/0xa0 schedule_preempt_disabled+0xa/0x10 __mutex_lock.constprop.0+0x271/0x600 blk_mq_quiesce_tagset+0x25/0xc0 nvme_dev_disable+0x9c/0x250 nvme_timeout+0x1fc/0x520 blk_mq_handle_expired+0x5c/0x90 bt_iter+0x7e/0x90 blk_mq_queue_tag_busy_iter+0x27e/0x550 ? __blk_mq_complete_request_remote+0x10/0x10 ? __blk_mq_complete_request_remote+0x10/0x10 ? __call_rcu_common.constprop.0+0x1c0/0x210 blk_mq_timeout_work+0x12d/0x170 process_one_work+0x12e/0x2d0 worker_thread+0x288/0x3a0 ? rescuer_thread+0x480/0x480 kthread+0xb8/0xe0 ? kthread_park+0x80/0x80 ret_from_fork+0x2d/0x50 ? kthread_park+0x80/0x80 ret_from_fork_asm+0x11/0x20 __schedule+0x47c/0xbb0 ? xas_find+0x161/0x1a0 schedule+0x1c/0xa0 blk_mq_freeze_queue_wait+0x3d/0x70 ? destroy_sched_domains_rcu+0x30/0x30 blk_mq_update_tag_set_shared+0x44/0x80 blk_mq_exit_queue+0x141/0x150 del_gendisk+0x25a/0x2d0 nvme_ns_remove+0xc9/0x170 nvme_remove_namespaces+0xc7/0x100 nvme_remove+0x62/0x150 pci_device_remove+0x23/0x60 device_release_driver_internal+0x159/0x200 unbind_store+0x99/0xa0 kernfs_fop_write_iter+0x112/0x1e0 vfs_write+0x2b1/0x3d0 ksys_write+0x4e/0xb0 do_syscall_64+0x5b/0x160 entry_SYSCALL_64_after_hwframe+0x4b/0x53The top stacktrace is showing nvme_timeout() called to handle nvmecommand timeout. timeout handler is trying to disable the controller andas a first step, it needs to blk_mq_quiesce_tagset() to tell blk-mq notto call queue callback handlers. The thread is stuck waiting forset->tag_list_lock as it tries to walk the queues in set->tag_list.The lock is held by the second thread in the bottom stack which iswaiting for one of queues to be frozen. The queue usage counter willdrop to zero after nvme_timeout() finishes, and this will not happenbecause the thread will wait for this mutex forever.Given that [un]quiescing queue is an operation that does not need tosleep, update blk_mq_[un]quiesce_tagset() to use RCU instead of takingset->tag_list_lock, update blk_mq_{add,del}_queue_tag_set() to use RCUsafe list operations.

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

Description: In the Linux kernel, the following vulnerability has been resolved:fsnotify: do not generate ACCESS/MODIFY events on child for special filesinotify/fanotify do not allow users with no read access to a file tosubscribe to events (e.g. IN_ACCESS/IN_MODIFY), but they do allow thesame user to subscribe for watching events on children when the userhas access to the parent directory (e.g. /dev).Users with no read access to a file but with read access to its parentdirectory can still stat the file and see if it was accessed/modifiedvia atime/mtime change.The same is not true for special files (e.g. /dev/null). Users will notgenerally observe atime/mtime changes when other users read/write tospecial files, only when someone sets atime/mtime via utimensat().Align fsnotify events with this stat behavior and do not generateACCESS/MODIFY events to parent watchers on read/write of special files.The events are still generated to parent watchers on utimensat().

CVE-2025-71097 Severity: Moderate CVSS3 score: 4.7

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

CVE-2025-68803 Severity: Moderate CVSS3 score: 4.6

Description: In the Linux kernel, the following vulnerability has been resolved:NFSD: NFSv4 file creation neglects setting ACLAn NFSv4 client that sets an ACL with a named principal during filecreation retrieves the ACL afterwards, and finds that it is only adefault ACL (based on the mode bits) and not the ACL that wasrequested during file creation. This violates RFC 8881 section6.4.1.3: "the ACL attribute is set as given".The issue occurs in nfsd_create_setattr(), which callsnfsd_attrs_valid() to determine whether to call nfsd_setattr().However, nfsd_attrs_valid() checks only for iattr changes andsecurity labels, but not POSIX ACLs. When only an ACL is present,the function returns false, nfsd_setattr() is skipped, and thePOSIX ACL is never applied to the inode.Subsequently, when the client retrieves the ACL, the server findsno POSIX ACL on the inode and returns one generated from the file'smode bits rather than returning the originally-specified ACL.

Description: In the Linux kernel, the following vulnerability has been resolved:arm64/fpsimd: Discard stale CPU state when handling SME trapsThe logic for handling SME traps manipulates saved FPSIMD/SVE/SME stateincorrectly, and a race with preemption can result in a task havingTIF_SME set and TIF_FOREIGN_FPSTATE clear even though the live CPU stateis stale (e.g. with SME traps enabled). This can result in warnings fromdo_sme_acc() where SME traps are not expected while TIF_SME is set:| /* With TIF_SME userspace shouldn't generate any traps */| if (test_and_set_thread_flag(TIF_SME))| WARN_ON(1);This is very similar to the SVE issue we fixed in commit: 751ecf6afd6568ad ("arm64/sve: Discard stale CPU state when handling SVE traps")The race can occur when the SME trap handler is preempted before andafter manipulating the saved FPSIMD/SVE/SME state, starting and ending onthe same CPU, e.g.| void do_sme_acc(unsigned long esr, struct pt_regs *regs)| {| // Trap on CPU 0 with TIF_SME clear, SME traps enabled| // task->fpsimd_cpu is 0.| // per_cpu_ptr(&fpsimd_last_state, 0) is task.|| ...|| // Preempted; migrated from CPU 0 to CPU 1.| // TIF_FOREIGN_FPSTATE is set.|| get_cpu_fpsimd_context();|| /* With TIF_SME userspace shouldn't generate any traps */| if (test_and_set_thread_flag(TIF_SME))| WARN_ON(1);|| if (!test_thread_flag(TIF_FOREIGN_FPSTATE)) {| unsigned long vq_minus_one =| sve_vq_from_vl(task_get_sme_vl(current)) - 1;| sme_set_vq(vq_minus_one);|| fpsimd_bind_task_to_cpu();| }|| put_cpu_fpsimd_context();|| // Preempted; migrated from CPU 1 to CPU 0.| // task->fpsimd_cpu is still 0| // If per_cpu_ptr(&fpsimd_last_state, 0) is still task then:| // - Stale HW state is reused (with SME traps enabled)| // - TIF_FOREIGN_FPSTATE is cleared| // - A return to userspace skips HW state restore| }Fix the case where the state is not live and TIF_FOREIGN_FPSTATE is setby calling fpsimd_flush_task_state() to detach from the saved CPUstate. This ensures that a subsequent context switch will not reuse thestale CPU state, and will instead set TIF_FOREIGN_FPSTATE, forcing thenew state to be reloaded from memory prior to a return to userspace.Note: this was originallly posted as [1].[ Rutland: rewrite commit message ]

CVE-2021-3521 Severity: Moderate CVSS3 score: 4.4

Description: There is a flaw in RPM's signature functionality. OpenPGP subkeys are associated with a primary key via a "binding signature." RPM does not check the binding signature of subkeys prior to importing them. If an attacker is able to add or socially engineer another party to add a malicious subkey to a legitimate public key, RPM could wrongly trust a malicious signature. The greatest impact of this flaw is to data integrity. To exploit this flaw, an attacker must either compromise an RPM repository or convince an administrator to install an untrusted RPM or public key. It is strongly recommended to only use RPMs and public keys from trusted sources.

Description: In the Linux kernel, the following vulnerability has been resolved:net: usb: aqc111: fix error handling of usbnet read callsSyzkaller, courtesy of syzbot, identified an error (see report [1]) inaqc111 driver, caused by incomplete sanitation of usb read calls'results. This problem is quite similar to the one fixed in commit920a9fa27e78 ("net: asix: add proper error handling of usb read errors").For instance, usbnet_read_cmd() may read fewer than 'size' bytes,even if the caller expected the full amount, and aqc111_read_cmd()will not check its result properly. As [1] shows, this may leadto MAC address in aqc111_bind() being only partly initialized,triggering KMSAN warnings.Fix the issue by verifying that the number of bytes read isas expected and not less.[1] Partial syzbot report:BUG: KMSAN: uninit-value in is_valid_ether_addr include/linux/etherdevice.h:208 [inline]BUG: KMSAN: uninit-value in usbnet_probe+0x2e57/0x4390 drivers/net/usb/usbnet.c:1830 is_valid_ether_addr include/linux/etherdevice.h:208 [inline] usbnet_probe+0x2e57/0x4390 drivers/net/usb/usbnet.c:1830 usb_probe_interface+0xd01/0x1310 drivers/usb/core/driver.c:396 call_driver_probe drivers/base/dd.c:-1 [inline] really_probe+0x4d1/0xd90 drivers/base/dd.c:658 __driver_probe_device+0x268/0x380 drivers/base/dd.c:800...Uninit was stored to memory at: dev_addr_mod+0xb0/0x550 net/core/dev_addr_lists.c:582 __dev_addr_set include/linux/netdevice.h:4874 [inline] eth_hw_addr_set include/linux/etherdevice.h:325 [inline] aqc111_bind+0x35f/0x1150 drivers/net/usb/aqc111.c:717 usbnet_probe+0xbe6/0x4390 drivers/net/usb/usbnet.c:1772 usb_probe_interface+0xd01/0x1310 drivers/usb/core/driver.c:396...Uninit was stored to memory at: ether_addr_copy include/linux/etherdevice.h:305 [inline] aqc111_read_perm_mac drivers/net/usb/aqc111.c:663 [inline] aqc111_bind+0x794/0x1150 drivers/net/usb/aqc111.c:713 usbnet_probe+0xbe6/0x4390 drivers/net/usb/usbnet.c:1772 usb_probe_interface+0xd01/0x1310 drivers/usb/core/driver.c:396 call_driver_probe drivers/base/dd.c:-1 [inline]...Local variable buf.i created at: aqc111_read_perm_mac drivers/net/usb/aqc111.c:656 [inline] aqc111_bind+0x221/0x1150 drivers/net/usb/aqc111.c:713 usbnet_probe+0xbe6/0x4390 drivers/net/usb/usbnet.c:1772

Also move fb_add_videomode() closer to the beginning ofdo_register_framebuffer() to avoid having to do the cleanup on fail.Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Description: In the Linux kernel, the following vulnerability has been resolved:fpga: fix potential null pointer deref in fpga_mgr_test_img_load_sgt()fpga_mgr_test_img_load_sgt() allocates memory for sgt usingkunit_kzalloc() however it does not check if the allocation failed.It then passes sgt to sg_alloc_table(), which passes it to__sg_alloc_table(). This function calls memset() on sgt in an attempt tozero it out. If the allocation fails then sgt will be NULL and thememset will trigger a NULL pointer dereference.Fix this by checking the allocation with KUNIT_ASSERT_NOT_ERR_OR_NULL().

CVE-2025-38508 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:x86/sev: Use TSC_FACTOR for Secure TSC frequency calculationWhen using Secure TSC, the GUEST_TSC_FREQ MSR reports a frequency based onthe nominal P0 frequency, which deviates slightly (typically ~0.2%) fromthe actual mean TSC frequency due to clocking parameters.Over extended VM uptime, this discrepancy accumulates, causing clock skewbetween the hypervisor and a SEV-SNP VM, leading to early timer interrupts asperceived by the guest.The guest kernel relies on the reported nominal frequency for TSC-basedtimekeeping, while the actual frequency set during SNP_LAUNCH_START maydiffer. This mismatch results in inaccurate time calculations, causing theguest to perceive hrtimers as firing earlier than expected.Utilize the TSC_FACTOR from the SEV firmware's secrets page (see "SecretsPage Format" in the SNP Firmware ABI Specification) to calculate the meanTSC frequency, ensuring accurate timekeeping and mitigating clock skew inSEV-SNP VMs.Use early_ioremap_encrypted() to map the secrets page asioremap_encrypted() uses kmalloc() which is not available during early TSCinitialization and causes a panic.

CVE-2025-38591 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Reject narrower access to pointer ctx fieldsThe following BPF program, simplified from a syzkaller repro, causes akernel warning: r0 = *(u8 *)(r1 + 169); exit;With pointer field sk being at offset 168 in __sk_buff. This access isdetected as a narrower read in bpf_skb_is_valid_access because itdoesn't match offsetof(struct __sk_buff, sk). It is therefore allowedand later proceeds to bpf_convert_ctx_access. Note that for the"is_narrower_load" case in the convert_ctx_accesses(), the insn->offis aligned, so the cnt may not be 0 because it matches theoffsetof(struct __sk_buff, sk) in the bpf_convert_ctx_access. However,the target_size stays 0 and the verifier errors with a kernel warning: verifier bug: error during ctx access conversion(1)This patch fixes that to return a proper "invalid bpf_context accessoff=X size=Y" error on the load instruction.The same issue affects multiple other fields in context structures thatallow narrow access. Some other non-affected fields (for sk_msg,sk_lookup, and sockopt) were also changed to use bpf_ctx_range_ptr forconsistency.Note this syzkaller crash was reported in the "Closes" link below, whichused to be about a different bug, fixed incommit fce7bd8e385a ("bpf/verifier: Handle BPF_LOAD_ACQ instructionsin insn_def_regno()"). Because syzbot somehow confused the two bugs,the new crash and repro didn't get reported to the mailing list.

That explains why there is no backref item for thatbytenr and why btrfs check is not reporting anything wrong.But this also shows another problem, as btrfs will do all the orphansubvolume cleanup at a read-write mount.So half-dropped subvolume should not exist after an RW mount, andbalance itself is also exclusive to subvolume cleanup, meaning weshouldn't hit a subvolume half-dropped during relocation.The root cause is, there is no orphan item for this subvolume.In fact there are 5 subvolumes from around 2021 that have the sameproblem.It looks like the original report has some older kernels running, andcaused those zombie subvolumes.Thankfully upstream commit 8d488a8c7ba2 ("btrfs: fix subvolume/snapshotdeletion not triggered on mount") has long fixed the bug.[ENHANCEMENT]For repairing such old fs, btrfs-progs will be enhanced.Considering how delayed the problem will show up (at run delayed reftime) and at that time we have to abort transaction already, it is toolate.Instead here we reject any half-dropped subvolume for reloc tree at theearliest time, preventing confusion and extra time wasted on debuggingsimilar bugs.

CVE-2025-39763 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:ACPI: APEI: send SIGBUS to current task if synchronous memory error not recoveredIf a synchronous error is detected as a result of user-space processtriggering a 2-bit uncorrected error, the CPU will take a synchronouserror exception such as Synchronous External Abort (SEA) on Arm64. Thekernel will queue a memory_failure() work which poisons the relatedpage, unmaps the page, and then sends a SIGBUS to the process, so thata system wide panic can be avoided.However, no memory_failure() work will be queued when abnormalsynchronous errors occur. These errors can include situations likeinvalid PA, unexpected severity, no memory failure config support,invalid GUID section, etc. In such a case, the user-space process willtrigger SEA again. This loop can potentially exceed the platformfirmware threshold or even trigger a kernel hard lockup, leading to asystem reboot.Fix it by performing a force kill if no memory_failure() work is queuedfor synchronous errors.[ rjw: Changelog edits ]

CVE-2025-39958 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:iommu/s390: Make attach succeed when the device was surprise removedWhen a PCI device is removed with surprise hotplug, there may still beattempts to attach the device to the default domain as part of tear downvia (__iommu_release_dma_ownership()), or because the removal happensduring probe (__iommu_probe_device()). In both cases zpci_register_ioat()fails with a cc value indicating that the device handle is invalid. Thisis because the device is no longer part of the instance as far as thehypervisor is concerned.Currently this leads to an error return and s390_iommu_attach_device()fails. This triggers the WARN_ON() in __iommu_group_set_domain_nofail()because attaching to the default domain must never fail.With the device fenced by the hypervisor no DMAs to or from memory arepossible and the IOMMU translations have no effect. Proceed as if theregistration was successful and let the hotplug event handling clean upthe device.This is similar to how devices in the error state are handled sincecommit 59bbf596791b ("iommu/s390: Make attach succeed even if the deviceis in error state") except that for removal the domain will not beregistered later. This approach was also previously discussed at thelink.Handle both cases, error state and removal, in a helper which checks ifthe error needs to be propagated or ignored. Avoid magic numbercondition codes by using the pre-existing, but never used, defines forPCI load/store condition codes and rename them to reflect that theyapply to all PCI instructions.

CVE-2025-39948 Severity: Moderate CVSS3 score: 4.3

Description: In the Linux kernel, the following vulnerability has been resolved:ice: fix Rx page leak on multi-buffer framesThe ice_put_rx_mbuf() function handles calling ice_put_rx_buf() for eachbuffer in the current frame. This function was introduced as part ofhandling multi-buffer XDP support in the ice driver.It works by iterating over the buffers from first_desc up to 1 plus thetotal number of fragments in the frame, cached from before the XDP programwas executed.If the hardware posts a descriptor with a size of 0, the logic used inice_put_rx_mbuf() breaks. Such descriptors get skipped and don't get addedas fragments in ice_add_xdp_frag. Since the buffer isn't counted as afragment, we do not iterate over it in ice_put_rx_mbuf(), and thus we don'tcall ice_put_rx_buf().Because we don't call ice_put_rx_buf(), we don't attempt to re-use thepage or free it. This leaves a stale page in the ring, as we don'tincrement next_to_alloc.The ice_reuse_rx_page() assumes that the next_to_alloc has been incrementedproperly, and that it always points to a buffer with a NULL page. Sincethis function doesn't check, it will happily recycle a page over the topof the next_to_alloc buffer, losing track of the old page.Note that this leak only occurs for multi-buffer frames. Theice_put_rx_mbuf() function always handles at least one buffer, so asingle-buffer frame will always get handled correctly. It is not clearprecisely why the hardware hands us descriptors with a size of 0 sometimes,but it happens somewhat regularly with "jumbo frames" used by 9K MTU.To fix ice_put_rx_mbuf(), we need to make sure to call ice_put_rx_buf() onall buffers between first_desc and next_to_clean. Borrow the logic of asimilar function in i40e used for this same purpose. Use the same logicalso in ice_get_pgcnts().Instead of iterating over just the number of fragments, use a loop whichiterates until the current index reaches to the next_to_clean element justpast the current frame. Unlike i40e, the ice_put_rx_mbuf() function doescall ice_put_rx_buf() on the last buffer of the frame indicating the end ofpacket.For non-linear (multi-buffer) frames, we need to take care when adjustingthe pagecnt_bias. An XDP program might release fragments from the tail ofthe frame, in which case that fragment page is already released. Onlyupdate the pagecnt_bias for the first descriptor and fragments stillremaining post-XDP program. Take care to only access the shared info forfragmented buffers, as this avoids a significant cache miss.The xdp_xmit value only needs to be updated if an XDP program is run, andonly once per packet. Drop the xdp_xmit pointer argument fromice_put_rx_mbuf(). Instead, set xdp_xmit in the ice_clean_rx_irq() functiondirectly. This avoids needing to pass the argument and avoids an extrabit-wise OR for each buffer in the frame.Move the increment of the ntc local variable to ensure its updated *before*all calls to ice_get_pgcnts() or ice_put_rx_mbuf(), as the loop logicrequires the index of the element just after the current frame.Now that we use an index pointer in the ring to identify the packet, we nolonger need to track or cache the number of fragments in the rx_ring.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: mpi3mr: Synchronous access b/w reset and tm thread for reply queueWhen the task management thread processes reply queues while the resetthread resets them, the task management thread accesses an invalid queue ID(0xFFFF), set by the reset thread, which points to unallocated memory,causing a crash.Add flag 'io_admin_reset_sync' to synchronize access between the reset,I/O, and admin threads. Before a reset, the reset handler sets this flag toblock I/O and admin processing threads. If any thread bypasses the initialcheck, the reset thread waits up to 10 seconds for processing to finish. Ifthe wait exceeds 10 seconds, the controller is marked as unrecoverable.

Description: In the Linux kernel, the following vulnerability has been resolved:ata: pata_via: Force PIO for ATAPI devices on VT6415/VT6330The controller has a hardware bug that can hard hang the system whendoing ATAPI DMAs without any trace of what happened. Depending on thedevice attached, it can also prevent the system from booting.In this case, the system hangs when reading the ATIP from optical mediawith cdrecord -vvv -atip on an _NEC DVD_RW ND-4571A 1-01 and anOptiarc DVD RW AD-7200A 1.06 attached to an ASRock 990FX Extreme 4,running at UDMA/33.The issue can be reproduced by running the same command with a cygwinbuild of cdrecord on WinXP, although it requires more attempts to causeit. The hang in that case is also resolved by forcing PIO. It doesn'tappear that VIA has produced any drivers for that OS, thus no knownworkaround exists.HDDs attached to the controller do not suffer from any DMA issues.

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-2025-68742 Severity: Moderate CVSS3 score: 4.1

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix invalid prog->stats access when update_effective_progs failsSyzkaller triggers an invalid memory access issue following faultinjection in update_effective_progs. The issue can be described asfollows:__cgroup_bpf_detach update_effective_progs compute_effective_progs bpf_prog_array_alloc <-- fault inject purge_effective_progs /* change to dummy_bpf_prog */ array->items[index] = &dummy_bpf_prog.prog---softirq start---__do_softirq ... __cgroup_bpf_run_filter_skb __bpf_prog_run_save_cb bpf_prog_run stats = this_cpu_ptr(prog->stats) /* invalid memory access */ flags = u64_stats_update_begin_irqsave(&stats->syncp)---softirq end--- static_branch_dec(&cgroup_bpf_enabled_key[atype])The reason is that fault injection caused update_effective_progs to failand then changed the original prog into dummy_bpf_prog.prog inpurge_effective_progs. Then a softirq came, and accessing the members ofdummy_bpf_prog.prog in the softirq triggers invalid mem access.To fix it, skip updating stats when stats is NULL.

CVE-2024-45310 Severity: Low CVSS3 score: 3.6

Description: runc is a CLI tool for spawning and running containers according to the OCI specification. runc 1.1.13 and earlier, as well as 1.2.0-rc2 and earlier, can be tricked into creating empty files or directories in arbitrary locations in the host filesystem by sharing a volume between two containers and exploiting a race with `os.MkdirAll`. While this could be used to create empty files, existing files would not be truncated. An attacker must have the ability to start containers using some kind of custom volume configuration. Containers using user namespaces are still affected, but the scope of places an attacker can create inodes can be significantly reduced. Sufficiently strict LSM policies (SELinux/Apparmor) can also in principle block this attack -- we suspect the industry standard SELinux policy may restrict this attack's scope but the exact scope of protection hasn't been analysed. This is exploitable using runc directly as well as through Docker and Kubernetes. The issue is fixed in runc v1.1.14 and v1.2.0-rc3.Some workarounds are available. Using user namespaces restricts this attack fairly significantly such that the attacker can only create inodes in directories that the remapped root user/group has write access to. Unless the root user is remapped to an actualuser on the host (such as with rootless containers that don't use `/etc/sub[ug]id`), this in practice means that an attacker would only be able to create inodes in world-writable directories. A strict enough SELinux or AppArmor policy could in principle also restrict the scope if a specific label is applied to the runc runtime, though neither the extent to which the standard existing policies block this attack nor what exact policies are needed to sufficiently restrict this attack have been thoroughly tested.

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

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

CVE-2025-24031 Severity: Moderate CVSS3 score: 3.3

Description: PAM-PKCS#11 is a Linux-PAM login module that allows a X.509 certificate based user login. In versions 0.6.12 and prior, the pam_pkcs11 module segfaults when a user presses ctrl-c/ctrl-d when they are asked for a PIN. When a user enters no PIN at all, `pam_get_pwd` will never initialize the password buffer pointer and as such `cleanse` will try to dereference an uninitialized pointer. On my system this pointer happens to have the value 3 most of the time when running sudo and as such it will segfault. The most likely impact to a system affected by this issue is an availability impact due to a daemon that uses PAM crashing. As of time of publication, a patch for the issue is unavailable.

CVE-2025-12781 Severity: Low CVSS3 score: 3.3

Description: When passing data to the b64decode(), standard_b64decode(), and urlsafe_b64decode() functions in the "base64" module the characters "+/" will always be accepted, regardless of the value of "altchars" parameter, typically used to establish an "alternative base64 alphabet" such as the URL safe alphabet. This behavior matches what is recommended in earlier base64 RFCs, but newer RFCs now recommend either dropping characters outside the specified base64 alphabet or raising an error. The old behavior has the possibility of causing data integrity issues.This behavior can only be insecure if your application uses an alternate base64 alphabet (without "+/"). If your application does not use the "altchars" parameter or the urlsafe_b64decode() function, then your application does not use an alternative base64 alphabet.The attached patches DOES NOT make the base64-decode behavior raise an error, as this would be a change in behavior and break existing programs. Instead, the patch deprecates the behavior which will be replaced with the newly recommended behavior in a future version of Python. Users are recommended to mitigate by verifying user-controlled inputs match the base64 alphabet they are expecting or verify that their application would not be affected if the b64decode() functions accepted "+" or "/" outside of altchars.

Description: In the Linux kernel, the following vulnerability has been resolved:arm64/fpsimd: Avoid clobbering kernel FPSIMD state with SMSTOPOn system with SME, a thread's kernel FPSIMD state may be erroneouslyclobbered during a context switch immediately after that state isrestored. Systems without SME are unaffected.If the CPU happens to be in streaming SVE mode before a context switchto a thread with kernel FPSIMD state, fpsimd_thread_switch() willrestore the kernel FPSIMD state using fpsimd_load_kernel_state() whilethe CPU is still in streaming SVE mode. When fpsimd_thread_switch()subsequently calls fpsimd_flush_cpu_state(), this will execute anSMSTOP, causing an exit from streaming SVE mode. The exit fromstreaming SVE mode will cause the hardware to reset a number ofFPSIMD/SVE/SME registers, clobbering the FPSIMD state.Fix this by calling fpsimd_flush_cpu_state() before restoring the kernelFPSIMD state.

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

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

CVE-2025-38623 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: pnv_php: Fix surprise plug detection and recoveryThe existing PowerNV hotplug code did not handle surprise plug eventscorrectly, leading to a complete failure of the hotplug system after deviceremoval and a required reboot to detect new devices.This comes down to two issues: 1) When a device is surprise removed, often the bridge upstream port will cause a PE freeze on the PHB. If this freeze is not cleared, the MSI interrupts from the bridge hotplug notification logic will not be received by the kernel, stalling all plug events on all slots associated with the PE. 2) When a device is removed from a slot, regardless of surprise or programmatic removal, the associated PHB/PE ls left frozen. If this freeze is not cleared via a fundamental reset, skiboot is unable to clear the freeze and cannot retrain / rescan the slot. This also requires a reboot to clear the freeze and redetect the device in the slot.Issue the appropriate unfreeze and rescan commands on hotplug events,and don't oops on hotplug if pci_bus_to_OF_node() returns NULL.[bhelgaas: tidy comments]

Description: In the Linux kernel, the following vulnerability has been resolved:media: uvcvideo: Mark invalid entities with id UVC_INVALID_ENTITY_IDPer UVC 1.1+ specification 3.7.2, units and terminals must have a non-zerounique ID.```Each Unit and Terminal within the video function is assigned a uniqueidentification number, the Unit ID (UID) or Terminal ID (TID), contained inthe bUnitID or bTerminalID field of the descriptor. The value 0x00 isreserved for undefined ID,```If we add a new entity with id 0 or a duplicated ID, it will be markedas UVC_INVALID_ENTITY_ID.In a previous attempt commit 3dd075fe8ebb ("media: uvcvideo: Requireentities to have a non-zero unique ID"), we ignored all the invalid units,this broke a lot of non-compatible cameras. Hopefully we are more luckythis time.This also prevents some syzkaller reproducers from triggering warnings dueto a chain of entities referring to themselves. In one particular case, anOutput Unit is connected to an Input Unit, both with the same ID of 1. Butwhen looking up for the source ID of the Output Unit, that same entity isfound instead of the input entity, which leads to such warnings.In another case, a backward chain was considered finished as the source IDwas 0. Later on, that entity was found, but its pads were not valid.Here is a sample stack trace for one of those cases.[ 20.650953] usb 1-1: new high-speed USB device number 2 using dummy_hcd[ 20.830206] usb 1-1: Using ep0 maxpacket: 8[ 20.833501] usb 1-1: config 0 descriptor??[ 21.038518] usb 1-1: string descriptor 0 read error: -71[ 21.038893] usb 1-1: Found UVC 0.00 device (2833:0201)[ 21.039299] uvcvideo 1-1:0.0: Entity type for entity Output 1 was not initialized![ 21.041583] uvcvideo 1-1:0.0: Entity type for entity Input 1 was not initialized![ 21.042218] ------------[ cut here ]------------[ 21.042536] WARNING: CPU: 0 PID: 9 at drivers/media/mc/mc-entity.c:1147 media_create_pad_link+0x2c4/0x2e0[ 21.043195] Modules linked in:[ 21.043535] CPU: 0 UID: 0 PID: 9 Comm: kworker/0:1 Not tainted 6.11.0-rc7-00030-g3480e43aeccf #444[ 21.044101] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.15.0-1 04/01/2014[ 21.044639] Workqueue: usb_hub_wq hub_event[ 21.045100] RIP: 0010:media_create_pad_link+0x2c4/0x2e0[ 21.045508] Code: fe e8 20 01 00 00 b8 f4 ff ff ff 48 83 c4 30 5b 41 5c 41 5d 41 5e 41 5f 5d c3 cc cc cc cc 0f 0b eb e9 0f 0b eb 0a 0f 0b eb 06 <0f> 0b eb 02 0f 0b b8 ea ff ff ff eb d4 66 2e 0f 1f 84 00 00 00 00[ 21.046801] RSP: 0018:ffffc9000004b318 EFLAGS: 00010246[ 21.047227] RAX: ffff888004e5d458 RBX: 0000000000000000 RCX: ffffffff818fccf1[ 21.047719] RDX: 000000000000007b RSI: 0000000000000000 RDI: ffff888004313290[ 21.048241] RBP: ffff888004313290 R08: 0001ffffffffffff R09: 0000000000000000[ 21.048701] R10: 0000000000000013 R11: 0001888004313290 R12: 0000000000000003[ 21.049138] R13: ffff888004313080 R14: ffff888004313080 R15: 0000000000000000[ 21.049648] FS: 0000000000000000(0000) GS:ffff88803ec00000(0000) knlGS:0000000000000000[ 21.050271] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 21.050688] CR2: 0000592cc27635b0 CR3: 000000000431c000 CR4: 0000000000750ef0[ 21.051136] PKRU: 55555554[ 21.051331] Call Trace:[ 21.051480] [ 21.051611] ? __warn+0xc4/0x210[ 21.051861] ? media_create_pad_link+0x2c4/0x2e0[ 21.052252] ? report_bug+0x11b/0x1a0[ 21.052540] ? trace_hardirqs_on+0x31/0x40[ 21.052901] ? handle_bug+0x3d/0x70[ 21.053197] ? exc_invalid_op+0x1a/0x50[ 21.053511] ? asm_exc_invalid_op+0x1a/0x20[ 21.053924] ? media_create_pad_link+0x91/0x2e0[ 21.054364] ? media_create_pad_link+0x2c4/0x2e0[ 21.054834] ? media_create_pad_link+0x91/0x2e0[ 21.055131] ? _raw_spin_unlock+0x1e/0x40[ 21.055441] ? __v4l2_device_register_subdev+0x202/0x210[ 21.055837] uvc_mc_register_entities+0x358/0x400[ 21.056144] uvc_register_chains+0x1---truncated---

CVE-2025-40101 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix memory leaks when rejecting a non SINGLE data profile without an RSTAt the end of btrfs_load_block_group_zone_info() the first thing we dois to ensure that if the mapping type is not a SINGLE one and there isno RAID stripe tree, then we return early with an error.Doing that, though, prevents the code from running the last calls fromthis function which are about freeing memory allocated during itsrun. Hence, in this case, instead of returning early, we set the retvalue and fall through the rest of the cleanup code.

CVE-2025-40105 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:vfs: Don't leak disconnected dentries on umountWhen user calls open_by_handle_at() on some inode that is not cached, wewill create disconnected dentry for it. If such dentry is a directory,exportfs_decode_fh_raw() will then try to connect this dentry to thedentry tree through reconnect_path(). It may happen for various reasons(such as corrupted fs or race with rename) that the call tolookup_one_unlocked() in reconnect_one() will fail to find the dentry weare trying to reconnect and instead create a new dentry under theparent. Now this dentry will not be marked as disconnected although theparent still may well be disconnected (at least in case thisinconsistency happened because the fs is corrupted and .. doesn't pointto the real parent directory). This creates inconsistency indisconnected flags but AFAICS it was mostly harmless. At least untilcommit f1ee616214cb ("VFS: don't keep disconnected dentries on d_anon")which removed adding of most disconnected dentries to sb->s_anon list.Thus after this commit cleanup of disconnected dentries implicitelyrelies on the fact that dput() will immediately reclaim such dentries.However when some leaf dentry isn't marked as disconnected, as in thescenario described above, the reclaim doesn't happen and the dentriesare "leaked". Memory reclaim can eventually reclaim them but otherwisethey stay in memory and if umount comes first, we hit infamous "Busyinodes after unmount" bug. Make sure all dentries created under adisconnected parent are marked as disconnected as well.

CVE-2025-40160 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:xen/events: Return -EEXIST for bound VIRQsChange find_virq() to return -EEXIST when a VIRQ is bound to adifferent CPU than the one passed in. With that, remove the BUG_ON()from bind_virq_to_irq() to propogate the error upwards.Some VIRQs are per-cpu, but others are per-domain or global. Those mustbe bound to CPU0 and can then migrate elsewhere. The lookup forper-domain and global will probably fail when migrated off CPU 0,especially when the current CPU is tracked. This now returns -EEXISTinstead of BUG_ON().A second call to bind a per-domain or global VIRQ is not expected, butmake it non-fatal to avoid trying to look up the irq, since we don'tknow which per_cpu(virq_to_irq) it will be in.

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

CVE-2026-1485 Severity: Low CVSS3 score: 3.3

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

CVE-2026-1757 Severity: Low CVSS3 score: 3.3

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

CVE-2025-58160 Severity: Low CVSS3 score: 3.1

Description: tracing is a framework for instrumenting Rust programs to collect structured, event-based diagnostic information. Prior to version 0.3.20, tracing-subscriber was vulnerable to ANSI escape sequence injection attacks. Untrusted user input containing ANSI escape sequences could be injected into terminal output when logged, potentially allowing attackers to manipulate terminal title bars, clear screens or modify terminal display, and potentially mislead users through terminal manipulation. tracing-subscriber version 0.3.20 fixes this vulnerability by escaping ANSI control characters when writing events to destinations that may be printed to the terminal. A workaround involves avoiding printing logs to terminal emulators without escaping ANSI control sequences.

CVE-2025-38267 Severity: Low CVSS3 score: 2.5

Description: In the Linux kernel, the following vulnerability has been resolved:ring-buffer: Do not trigger WARN_ON() due to a commit_overrunWhen reading a memory mapped buffer the reader page is just swapped outwith the last page written in the write buffer. If the reader page is thesame as the commit buffer (the buffer that is currently being written to)it was assumed that it should never have missed events. If it does, ittriggers a WARN_ON_ONCE().But there just happens to be one scenario where this can legitimatelyhappen. That is on a commit_overrun. A commit overrun is when an interruptpreempts an event being written to the buffer and then the interrupt addsso many new events that it fills and wraps the buffer back to the commit.Any new events would then be dropped and be reported as "missed_events".In this case, the next page to read is the commit buffer and after theswap of the reader page, the reader page will be the commit buffer, butthis time there will be missed events and this triggers the followingwarning: ------------[ cut here ]------------ WARNING: CPU: 2 PID: 1127 at kernel/trace/ring_buffer.c:7357 ring_buffer_map_get_reader+0x49a/0x780 Modules linked in: kvm_intel kvm irqbypass CPU: 2 UID: 0 PID: 1127 Comm: trace-cmd Not tainted 6.15.0-rc7-test-00004-g478bc2824b45-dirty #564 PREEMPT Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2 04/01/2014 RIP: 0010:ring_buffer_map_get_reader+0x49a/0x780 Code: 00 00 00 48 89 fe 48 c1 ee 03 80 3c 2e 00 0f 85 ec 01 00 00 4d 3b a6 a8 00 00 00 0f 85 8a fd ff ff 48 85 c0 0f 84 55 fe ff ff <0f> 0b e9 4e fe ff ff be 08 00 00 00 4c 89 54 24 58 48 89 54 24 50 RSP: 0018:ffff888121787dc0 EFLAGS: 00010002 RAX: 00000000000006a2 RBX: ffff888100062800 RCX: ffffffff8190cb49 RDX: ffff888126934c00 RSI: 1ffff11020200a15 RDI: ffff8881010050a8 RBP: dffffc0000000000 R08: 0000000000000000 R09: ffffed1024d26982 R10: ffff888126934c17 R11: ffff8881010050a8 R12: ffff888126934c00 R13: ffff8881010050b8 R14: ffff888101005000 R15: ffff888126930008 FS: 00007f95c8cd7540(0000) GS:ffff8882b576e000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f95c8de4dc0 CR3: 0000000128452002 CR4: 0000000000172ef0 Call Trace: ? __pfx_ring_buffer_map_get_reader+0x10/0x10 tracing_buffers_ioctl+0x283/0x370 __x64_sys_ioctl+0x134/0x190 do_syscall_64+0x79/0x1c0 entry_SYSCALL_64_after_hwframe+0x76/0x7e RIP: 0033:0x7f95c8de48db Code: 00 48 89 44 24 18 31 c0 48 8d 44 24 60 c7 04 24 10 00 00 00 48 89 44 24 08 48 8d 44 24 20 48 89 44 24 10 b8 10 00 00 00 0f 05 <89> c2 3d 00 f0 ff ff 77 1c 48 8b 44 24 18 64 48 2b 04 25 28 00 00 RSP: 002b:00007ffe037ba110 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 RAX: ffffffffffffffda RBX: 00007ffe037bb2b0 RCX: 00007f95c8de48db RDX: 0000000000000000 RSI: 0000000000005220 RDI: 0000000000000006 RBP: 00007ffe037ba180 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000 R13: 00007ffe037bb6f8 R14: 00007f95c9065000 R15: 00005575c7492c90 irq event stamp: 5080 hardirqs last enabled at (5079): [] _raw_spin_unlock_irqrestore+0x50/0x70 hardirqs last disabled at (5080): [] _raw_spin_lock_irqsave+0x63/0x70 softirqs last enabled at (4182): [] handle_softirqs+0x552/0x710 softirqs last disabled at (4159): [] __irq_exit_rcu+0x107/0x210 ---[ end trace 0000000000000000 ]---The above was triggered by running on a kernel with both lockdep and KASANas well as kmemleak enabled and executing the following command: # perf record -o perf-test.dat -a -- trace-cmd record --nosplice -e all -p function hackbench 50With perf interjecting a lot of interrupts and trace-cmd enabling allevents as well as function tracing, with lockdep, KASAN and kmemleakenabled, it could cause an interrupt preempting an event being written toadd enough event---truncated---

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:powerpc/bpf: fix JIT code size calculation of bpf trampolinearch_bpf_trampoline_size() provides JIT size of the BPF trampolinebefore the buffer for JIT'ing it is allocated. The total number ofinstructions emitted for BPF trampoline JIT code depends on wherethe final image is located. So, the size arrived at with the dummypass in arch_bpf_trampoline_size() can vary from the actual sizeneeded in arch_prepare_bpf_trampoline(). When the instructionsaccounted in arch_bpf_trampoline_size() is less than the number ofinstructions emitted during the actual JIT compile of the trampoline,the below warning is produced: WARNING: CPU: 8 PID: 204190 at arch/powerpc/net/bpf_jit_comp.c:981 __arch_prepare_bpf_trampoline.isra.0+0xd2c/0xdccwhich is: /* Make sure the trampoline generation logic doesn't overflow */ if (image && WARN_ON_ONCE(&image[ctx->idx] > (u32 *)rw_image_end - BPF_INSN_SAFETY)) {So, during the dummy pass, instead of providing some arbitrary imagelocation, account for maximum possible instructions if and when thereis a dependency with image location for JIT'ing.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: dwc3: Remove WARN_ON for device endpoint command timeoutsThis commit addresses a rarely observed endpoint command timeoutwhich causes kernel panic due to warn when 'panic_on_warn' is enabledand unnecessary call trace prints when 'panic_on_warn' is disabled.It is seen during fast software-controlled connect/disconnect testcases.The following is one such endpoint command timeout that we observed:1. Connect =======->dwc3_thread_interrupt ->dwc3_ep0_interrupt ->configfs_composite_setup ->composite_setup ->usb_ep_queue ->dwc3_gadget_ep0_queue ->__dwc3_gadget_ep0_queue ->__dwc3_ep0_do_control_data ->dwc3_send_gadget_ep_cmd2. Disconnect ==========->dwc3_thread_interrupt ->dwc3_gadget_disconnect_interrupt ->dwc3_ep0_reset_state ->dwc3_ep0_end_control_data ->dwc3_send_gadget_ep_cmdIn the issue scenario, in Exynos platforms, we observed that controltransfers for the previous connect have not yet been completed and endtransfer command sent as a part of the disconnect sequence andprocessing of USB_ENDPOINT_HALT feature request from the host timeout.This maybe an expected scenario since the controller is processing EPcommands sent as a part of the previous connect. It maybe better toremove WARN_ON in all places where device endpoint commands are sent toavoid unnecessary kernel panic due to warn.

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

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

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