CVE-2026-1299 Severity: Important CVSS3 score: 8.2

Description: The email module, specifically the "BytesGenerator" class, didn't properly quote newlines for email headers when serializing an email message allowing for header injection when an email is serialized. This is only applicable if using "LiteralHeader" writing headers that don't respect email folding rules, the new behavior will reject the incorrectly folded headers in "BytesGenerator".

CVE-2026-1484 Severity: Important CVSS3 score: 8.1

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

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

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

CVE-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-2025-71225 Severity: Important CVSS3 score: 7.8

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

CVE-2026-0861 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-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: In the Linux kernel, the following vulnerability has been resolved:ipv6: BUG() in pskb_expand_head() as part of calipso_skbuff_setattr()There exists a kernel oops caused by a BUG_ON(nhead < 0) atnet/core/skbuff.c:2232 in pskb_expand_head().This bug is triggered as part of the calipso_skbuff_setattr()routine when skb_cow() is passed headroom > INT_MAX(i.e. (int)(skb_headroom(skb) + len_delta) < 0).The root cause of the bug is due to an implicit integer cast in__skb_cow(). The check (headroom > skb_headroom(skb)) is meant to ensurethat delta = headroom - skb_headroom(skb) is never negative, otherwisewe will trigger a BUG_ON in pskb_expand_head(). However, ifheadroom > INT_MAX and delta <= -NET_SKB_PAD, the check passes, deltabecomes negative, and pskb_expand_head() is passed a negative value fornhead.Fix the trigger condition in calipso_skbuff_setattr().

CVE-2026-23220 Severity: Important CVSS3 score: 7.5

Description: In the Linux kernel, the following vulnerability has been resolved:ksmbd: fix infinite loop caused by next_smb2_rcv_hdr_off reset in error pathsThe problem occurs when a signed request fails smb2 signature verificationcheck. In __process_request(), if check_sign_req() returns an error,set_smb2_rsp_status(work, STATUS_ACCESS_DENIED) is called.set_smb2_rsp_status() set work->next_smb2_rcv_hdr_off as zero. By resettingnext_smb2_rcv_hdr_off to zero, the pointer to the next command in the chainis lost. Consequently, is_chained_smb2_message() continues to point tothe same request header instead of advancing. If the header's NextCommandfield is non-zero, the function returns true, causing __handle_ksmbd_work()to repeatedly process the same failed request in an infinite loop.This results in the kernel log being flooded with "bad smb2 signature"messages and high CPU usage.This patch fixes the issue by changing the return value fromSERVER_HANDLER_CONTINUE to SERVER_HANDLER_ABORT. This ensures thatthe processing loop terminates immediately rather than attempting tocontinue from an invalidated offset.

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: aloop: Fix racy access at PCM triggerThe PCM trigger callback of aloop driver tries to check the PCM stateand stop the stream of the tied substream in the corresponding cable.Since both check and stop operations are performed outside the cablelock, this may result in UAF when a program attempts to triggerfrequently while opening/closing the tied stream, as spotted byfuzzers.For addressing the UAF, this patch changes two things:- It covers the most of code in loopback_check_format() with cable->lock spinlock, and add the proper NULL checks. This avoids already some racy accesses.- In addition, now we try to check the state of the capture PCM stream that may be stopped in this function, which was the major pain point leading to UAF.

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

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

CVE-2026-23066 Severity: Important CVSS3 score: 7.0

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

CVE-2026-23074 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: Enforce that teql can only be used as root qdiscDesign intent of teql is that it is only supposed to be used as root qdisc.We need to check for that constraint.Although not important, I will describe the scenario that unearthed thisissue for the curious.GangMin Kim managed to concot a scenario as follows:ROOT qdisc 1:0 (QFQ) ├── class 1:1 (weight=15, lmax=16384) netem with delay 6.4s ── class 1:2 (weight=1, lmax=1514) teqlGangMin sends a packet which is enqueued to 1:1 (netem).Any invocation of dequeue by QFQ from this class will not return a packetuntil after 6.4s. In the meantime, a second packet is sent and it lands on1:2. teql's enqueue will return success and this will activate class 1:2.Main issue is that teql only updates the parent visible qlen (sch->q.qlen)at dequeue. Since QFQ will only call dequeue if peek succeeds (and teql'speek always returns NULL), dequeue will never be called and thus the qlenwill remain as 0. With that in mind, when GangMin updates 1:2's lmax value,the qfq_change_class calls qfq_deact_rm_from_agg. Since the child qdisc'sqlen was not incremented, qfq fails to deactivate the class, but stillfrees its pointers from the aggregate. So when the first packet isrescheduled after 6.4 seconds (netem's delay), a dangling pointer isaccessed causing GangMin's causing a UAF.

Description: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Prior to 1.6.55, an out-of-bounds read vulnerability exists in the png_set_quantize() API function. When the function is called with no histogram and the number of colors in the palette is more than twice the maximum supported by the user's display, certain palettes will cause the function to enter into an infinite loop that reads past the end of an internal heap-allocated buffer. The images that trigger this vulnerability are valid per the PNG specification. This vulnerability is fixed in 1.6.55.

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

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

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

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().

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

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

CVE-2026-23057 Severity: Moderate CVSS3 score: 6.6

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

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

Description: Vim is an open source, command line text editor. Prior to version 9.1.2132, a heap buffer overflow vulnerability exists in Vim's tag file resolution logic when processing the 'helpfile' option. The vulnerability is located in the get_tagfname() function in src/tag.c. When processing help file tags, Vim copies the user-controlled 'helpfile' option value into a fixed-size heap buffer of MAXPATHL + 1 bytes (typically 4097 bytes) using an unsafe STRCPY() operation without any bounds checking. This issue has been patched in version 9.1.2132.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:platform/x86: hp-bioscfg: Fix out-of-bounds array access in ACPI package parsingThe hp_populate_*_elements_from_package() functions in the hp-bioscfgdriver contain out-of-bounds array access vulnerabilities.These functions parse ACPI packages into internal data structures usinga for loop with index variable 'elem' that iterates throughenum_obj/integer_obj/order_obj/password_obj/string_obj arrays.When processing multi-element fields like PREREQUISITES andENUM_POSSIBLE_VALUES, these functions read multiple consecutive arrayelements using expressions like 'enum_obj[elem + reqs]' and'enum_obj[elem + pos_values]' within nested loops.The bug is that the bounds check only validated elem, but did not considerthe additional offset when accessing elem + reqs or elem + pos_values.The fix changes the bounds check to validate the actual accessed index.

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

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

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

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

CVE-2026-24401 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-2025-71152 Severity: Moderate CVSS3 score: 6.3

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

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

CVE-2025-40126 Severity: Moderate CVSS3 score: 6.1

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

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

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

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

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

Description: In 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.

[1] is required as a dependence: it was not explicitly marked asa fix, but it is one and it has already been backported before [3]. Inother words, this commit should be backported up to [3], including [2]and [1] if that's not already there.

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: target: iscsi: Fix use-after-free in iscsit_dec_session_usage_count()In iscsit_dec_session_usage_count(), the function calls complete() whileholding the sess->session_usage_lock. Similar to the connection usage countlogic, the waiter signaled by complete() (e.g., in the session releasepath) may wake up and free the iscsit_session structure immediately.This creates a race condition where the current thread may attempt toexecute spin_unlock_bh() on a session structure that has already beendeallocated, resulting in a KASAN slab-use-after-free.To resolve this, release the session_usage_lock before calling complete()to ensure all dereferences of the sess pointer are finished before thewaiter is allowed to proceed with deallocation.

CVE-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.

The innermostOVS_NSH_KEY_ATTR_BASE/MD1/MD2 are OK'ed by the nla_for_each_nested()inside nsh_key_put_from_nlattr(). But nothing checks if the attributein the middle is OK. We don't even check that this attribute is theOVS_KEY_ATTR_NSH. We just do a double unwrap with a pair of nla_data()calls - first time directly while calling validate_push_nsh() and thesecond time as part of the nla_for_each_nested() macro, which isn'tsafe, potentially causing invalid memory access if the size of thisattribute is incorrect. The failure may not be noticed duringvalidation due to larger netlink buffer, but cause trouble later duringaction execution where the buffer is allocated exactly to the size: BUG: KASAN: slab-out-of-bounds in nsh_hdr_from_nlattr+0x1dd/0x6a0 [openvswitch] Read of size 184 at addr ffff88816459a634 by task a.out/22624 CPU: 8 UID: 0 PID: 22624 6.18.0-rc7+ #115 PREEMPT(voluntary) Call Trace: dump_stack_lvl+0x51/0x70 print_address_description.constprop.0+0x2c/0x390 kasan_report+0xdd/0x110 kasan_check_range+0x35/0x1b0 __asan_memcpy+0x20/0x60 nsh_hdr_from_nlattr+0x1dd/0x6a0 [openvswitch] push_nsh+0x82/0x120 [openvswitch] do_execute_actions+0x1405/0x2840 [openvswitch] ovs_execute_actions+0xd5/0x3b0 [openvswitch] ovs_packet_cmd_execute+0x949/0xdb0 [openvswitch] genl_family_rcv_msg_doit+0x1d6/0x2b0 genl_family_rcv_msg+0x336/0x580 genl_rcv_msg+0x9f/0x130 netlink_rcv_skb+0x11f/0x370 genl_rcv+0x24/0x40 netlink_unicast+0x73e/0xaa0 netlink_sendmsg+0x744/0xbf0 __sys_sendto+0x3d6/0x450 do_syscall_64+0x79/0x2c0 entry_SYSCALL_64_after_hwframe+0x76/0x7e Let's add some checks that the attribute is properly sized and it'sthe only one attribute inside the action.

Therefore, using `<=`accesses one element past the end.Fix the issues by using `<` instead of `<=`, ensuring we do not exceedthe bounds.[1] KASAN splat about rss_key_size off-by-one BUG: KASAN: slab-out-of-bounds in iavf_config_rss+0x619/0x800 Read of size 4 at addr ffff888102c50134 by task kworker/u8:6/63 CPU: 0 UID: 0 PID: 63 Comm: kworker/u8:6 Not tainted 6.18.0-rc2-enjuk-tnguy-00378-g3005f5b77652-dirty #156 PREEMPT(voluntary) Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2 04/01/2014 Workqueue: iavf iavf_watchdog_task Call Trace: dump_stack_lvl+0x6f/0xb0 print_report+0x170/0x4f3 kasan_report+0xe1/0x1a0 iavf_config_rss+0x619/0x800 iavf_watchdog_task+0x2be7/0x3230 process_one_work+0x7fd/0x1420 worker_thread+0x4d1/0xd40 kthread+0x344/0x660 ret_from_fork+0x249/0x320 ret_from_fork_asm+0x1a/0x30 Allocated by task 63: kasan_save_stack+0x30/0x50 kasan_save_track+0x14/0x30 __kasan_kmalloc+0x7f/0x90 __kmalloc_noprof+0x246/0x6f0 iavf_watchdog_task+0x28fc/0x3230 process_one_work+0x7fd/0x1420 worker_thread+0x4d1/0xd40 kthread+0x344/0x660 ret_from_fork+0x249/0x320 ret_from_fork_asm+0x1a/0x30 The buggy address belongs to the object at ffff888102c50100 which belongs to the cache kmalloc-64 of size 64 The buggy address is located 0 bytes to the right of allocated 52-byte region [ffff888102c50100, ffff888102c50134) The buggy address belongs to the physical page: page: refcount:0 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x102c50 flags: 0x200000000000000(node=0|zone=2) page_type: f5(slab) raw: 0200000000000000 ffff8881000418c0 dead000000000122 0000000000000000 raw: 0000000000000000 0000000080200020 00000000f5000000 0000000000000000 page dumped because: kasan: bad access detected Memory state around the buggy address: ffff888102c50000: 00 00 00 00 00 00 00 fc fc fc fc fc fc fc fc fc ffff888102c50080: 00 00 00 00 00 00 00 fc fc fc fc fc fc fc fc fc >ffff888102c50100: 00 00 00 00 00 00 04 fc fc fc fc fc fc fc fc fc ^ ffff888102c50180: 00 00 00 00 00 00 00 00 fc fc fc fc fc fc fc fc ffff888102c50200: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc

Description: In the Linux kernel, the following vulnerability has been resolved:interconnect: Don't access req_list while it's being manipulatedThe icc_lock mutex was split into separate icc_lock and icc_bw_lockmutexes in [1] to avoid lockdep splats. However, this didn't adequatelyprotect access to icc_node::req_list.The icc_set_bw() function will eventually iterate over req_list whileonly holding icc_bw_lock, but req_list can be modified while onlyholding icc_lock. This causes races between icc_set_bw(), of_icc_get(),and icc_put().Example A: CPU0 CPU1 ---- ---- icc_set_bw(path_a) mutex_lock(&icc_bw_lock); icc_put(path_b) mutex_lock(&icc_lock); aggregate_requests() hlist_for_each_entry(r, ... hlist_del(...

Fix this by ensuring icc_bw_lock is always held before manipulatingicc_node::req_list. The additional places icc_bw_lock is held don'tperform any memory allocations, so we should still be safe from theoriginal lockdep splats that motivated the separate locks.[1] commit af42269c3523 ("interconnect: Fix locking for runpm vs reclaim")

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:net: kcm: Fix race condition in kcm_unattach()syzbot found a race condition when kcm_unattach(psock)and kcm_release(kcm) are executed at the same time.kcm_unattach() is missing a check of the flagkcm->tx_stopped before calling queue_work().If the kcm has a reserved psock, kcm_unattach() might get executedbetween cancel_work_sync() and unreserve_psock() in kcm_release(),requeuing kcm->tx_work right before kcm gets freed in kcm_done().Remove kcm->tx_stopped and replace it by the lesserror-prone disable_work_sync().

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.

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-2025-39776 Severity: Moderate CVSS3 score: 5.5

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

Description: In the Linux kernel, the following vulnerability has been resolved:efi: stmm: Fix incorrect buffer allocation methodThe communication buffer allocated by setup_mm_hdr() is later on passedto tee_shm_register_kernel_buf(). The latter expects those buffers to becontiguous pages, but setup_mm_hdr() just uses kmalloc(). That can causevarious corruptions or BUGs, specifically since commit 9aec2fb0fd5e("slab: allocate frozen pages"), though it was broken before as well.Fix this by using alloc_pages_exact() instead of kmalloc().

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

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

CVE-2025-39910 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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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.

During device detachment, the original implementationcalls flush_workqueue() in psmouse_disconnect() to ensurecompletion of dev3_register_work. However, the flush_workqueue()in psmouse_disconnect() only blocks and waits for work items thatwere already queued to the workqueue prior to its invocation. Anywork items submitted after flush_workqueue() is called are notincluded in the set of tasks that the flush operation awaits.This means that after flush_workqueue() has finished executing,the dev3_register_work could still be scheduled. Although thepsmouse state is set to PSMOUSE_CMD_MODE in psmouse_disconnect(),the scheduling of dev3_register_work remains unaffected.The race condition can occur as follows:CPU 0 (cleanup path) | CPU 1 (delayed work)psmouse_disconnect() | psmouse_set_state() | flush_workqueue() | alps_report_bare_ps2_packet() alps_disconnect() | psmouse_queue_work() kfree(priv); // FREE | alps_register_bare_ps2_mouse() | priv = container_of(work...); // USE | priv->dev3 // USEAdd disable_delayed_work_sync() in alps_disconnect() to ensurethat dev3_register_work is properly canceled and prevented fromexecuting after the alps_data structure has been deallocated.This bug is identified by static analysis.

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

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

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

Thisties the lifetime of all the btusb data to the binding of a driver toone interface, INTF. In a driver that binds to other interfaces, ISOCand DIAG, this is an accident waiting to happen.The issue is revealed in btusb_disconnect(), where callingusb_driver_release_interface(&btusb_driver, data->intf) will have devmfree the data that is also being used by the other interfaces of thedriver that may not be released yet.To fix this, revert the use of devm and go back to freeing memoryexplicitly.

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

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

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

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

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

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:iommu/sva: invalidate stale IOTLB entries for kernel address spaceIntroduce a new IOMMU interface to flush IOTLB paging cache entries forthe CPU kernel address space. This interface is invoked from the x86architecture code that manages combined user and kernel page tables,specifically before any kernel page table page is freed and reused.This addresses the main issue with vfree() which is a common occurrenceand can be triggered by unprivileged users. While this resolves theprimary problem, it doesn't address some extremely rare case related tomemory unplug of memory that was present as reserved memory at boot, whichcannot be triggered by unprivileged users. The discussion can be found atthe link below.Enable SVA on x86 architecture since the IOMMU can now receivenotification to flush the paging cache before freeing the CPU kernel pagetable pages.

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: Fix potential block overflow that cause system hangWhen a user executes the FITRIM command, an underflow can occur whencalculating nblocks if end_block is too small. Since nblocks is oftype sector_t, which is u64, a negative nblocks value will become avery large positive integer. This ultimately leads to the block layerfunction __blkdev_issue_discard() taking an excessively long time toprocess the bio chain, and the ns_segctor_sem lock remains held for along period. This prevents other tasks from acquiring the ns_segctor_semlock, resulting in the hang reported by syzbot in [1].If the ending block is too small, typically if it is smaller than 4KiBrange, depending on the usage of the segment 0, it may be possible toattempt a discard request beyond the device size causing the hang.Exiting successfully and assign the discarded size (0 in this case)to range->len.Although the start and len values in the user input range are too small,a conservative strategy is adopted here to safely ignore them, which isequivalent to a no-op; it will not perform any trimming and will notthrow an error.[1]task:segctord state:D stack:28968 pid:6093 tgid:6093 ppid:2 task_flags:0x200040 flags:0x00080000Call Trace: rwbase_write_lock+0x3dd/0x750 kernel/locking/rwbase_rt.c:272 nilfs_transaction_lock+0x253/0x4c0 fs/nilfs2/segment.c:357 nilfs_segctor_thread_construct fs/nilfs2/segment.c:2569 [inline] nilfs_segctor_thread+0x6ec/0xe00 fs/nilfs2/segment.c:2684[ryusuke: corrected part of the commit message about the consequences]

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:libceph: make calc_target() set t->paused, not just clear itCurrently calc_target() clears t->paused if the request shouldn't bepaused anymore, but doesn't ever set t->paused even though it's able todetermine when the request should be paused. Setting t->paused is leftto __submit_request() which is fine for regular requests but doesn'twork for linger requests -- since __submit_request() doesn't operateon linger requests, there is nowhere for lreq->t.paused to be set.One consequence of this is that watches don't get reestablished onpaused -> unpaused transitions in cases where requests have been pausedlong enough for the (paused) unwatch request to time out and for thesubsequent (re)watch request to enter the paused state.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:perf: sched: Fix perf crash with new is_user_task() helperIn order to do a user space stacktrace the current task needs to be a usertask that has executed in user space. It use to be possible to test if atask is a user task or not by simply checking the task_struct mm field. Ifit was non NULL, it was a user task and if not it was a kernel task.But things have changed over time, and some kernel tasks now have theirown mm field.An idea was made to instead test PF_KTHREAD and two functions were used towrap this check in case it became more complex to test if a task was auser task or not[1]. But this was rejected and the C code simply checkedthe PF_KTHREAD directly.It was later found that not all kernel threads set PF_KTHREAD. The io-uringhelpers instead set PF_USER_WORKER and this needed to be added as well.But checking the flags is still not enough. There's a very small windowwhen a task exits that it frees its mm field and it is set back to NULL.If perf were to trigger at this moment, the flags test would say its auser space task but when perf would read the mm field it would crash withat NULL pointer dereference.Now there are flags that can be used to test if a task is exiting, butthey are set in areas that perf may still want to profile the user spacetask (to see where it exited). The only real test is to check both theflags and the mm field.Instead of making this modification in every location, create a newis_user_task() helper function that does all the tests needed to know ifit is safe to read the user space memory or not.[1] https://lore.kernel.org/all/20250425204120.639530125@goodmis.org/

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

Description: Vim is an open source, command line text editor. Prior to 9.1.2148, a stack buffer overflow vulnerability exists in Vim's NetBeans integration when processing the specialKeys command, affecting Vim builds that enable and use the NetBeans feature. The Stack buffer overflow exists in special_keys() (in src/netbeans.c). The while (*tok) loop writes two bytes per iteration into a 64-byte stack buffer (keybuf) with no bounds check. A malicious NetBeans server can overflow keybuf with a single specialKeys command. The issue has been fixed as of Vim patch v9.1.2148.

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

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

CVE-2025-40303 Severity: Moderate CVSS3 score: 5.3

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

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

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

CVE-2026-0992 Severity: Moderate CVSS3 score: 5.3

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

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

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

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]

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

Description: In the Linux kernel, the following vulnerability has been resolved:accel/ivpu: Fix locking order in ivpu_job_submitFix deadlock in job submission and abort handling.When a thread aborts currently executing jobs due to a fault,it first locks the global lock protecting submitted_jobs (#1).After the last job is destroyed, it proceeds to release the related contextand locks file_priv (#2). Meanwhile, in the job submission thread,the file_priv lock (#2) is taken first, and then the submitted_jobslock (#1) is obtained when a job is added to the submitted jobs list. CPU0 CPU1 ---- ---- (for example due to a fault) (jobs submissions keep coming) lock(&vdev->submitted_jobs_lock) #1 ivpu_jobs_abort_all() job_destroy() lock(&file_priv->lock) #2 lock(&vdev->submitted_jobs_lock) #1 file_priv_release() lock(&vdev->context_list_lock) lock(&file_priv->lock) #2This order of locking causes a deadlock. To resolve this issue,change the order of locking in ivpu_job_submit().

Description: In the Linux kernel, the following vulnerability has been resolved:mm/kmemleak: avoid deadlock by moving pr_warn() outside kmemleak_lockWhen netpoll is enabled, calling pr_warn_once() while holdingkmemleak_lock in mem_pool_alloc() can cause a deadlock due to lockinversion with the netconsole subsystem. This occurs becausepr_warn_once() may trigger netpoll, which eventually leads to__alloc_skb() and back into kmemleak code, attempting to reacquirekmemleak_lock.This is the path for the deadlock.mem_pool_alloc() -> raw_spin_lock_irqsave(&kmemleak_lock, flags); -> pr_warn_once() -> netconsole subsystem -> netpoll -> __alloc_skb -> __create_object -> raw_spin_lock_irqsave(&kmemleak_lock, flags);Fix this by setting a flag and issuing the pr_warn_once() afterkmemleak_lock is released.

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

Description: In the Linux kernel, the following vulnerability has been resolved:block: Use RCU in blk_mq_[un]quiesce_tagset() instead of set->tag_list_lockblk_mq_{add,del}_queue_tag_set() functions add and remove queues fromtagset, the functions make sure that tagset and queues are marked asshared when two or more queues are attached to the same tagset.Initially a tagset starts as unshared and when the number of addedqueues reaches two, blk_mq_add_queue_tag_set() marks it as shared alongwith all the queues attached to it. 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. Also, delete INIT_LIST_HEAD(&q->tag_set_list)in blk_mq_del_queue_tag_set() because we can not re-initialize it whilethe list is being traversed under RCU. The deleted queue will not beadded/deleted to/from a tagset and it will be freed in blk_free_queue()after the end of RCU grace period.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:fsnotify: do not generate ACCESS/MODIFY events on child for special filesinotify/fanotify do not allow users with no read access to a file tosubscribe to events (e.g. IN_ACCESS/IN_MODIFY), but they do allow thesame user to subscribe for watching events on children when the userhas access to the parent directory (e.g. /dev).Users with no read access to a file but with read access to its parentdirectory can still stat the file and see if it was accessed/modifiedvia atime/mtime change.The same is not true for special files (e.g. /dev/null). Users will notgenerally observe atime/mtime changes when other users read/write tospecial files, only when someone sets atime/mtime via utimensat().Align fsnotify events with this stat behavior and do not generateACCESS/MODIFY events to parent watchers on read/write of special files.The events are still generated to parent watchers on utimensat(). Thiscloses some side-channels that could be possibly used for informationexfiltration [1].[1] https://snee.la/pdf/pubs/file-notification-attacks.pdf

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.

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

CVE-2025-71194 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix deadlock in wait_current_trans() due to ignored transaction typeWhen wait_current_trans() is called during start_transaction(), itcurrently waits for a blocked transaction without considering whetherthe given transaction type actually needs to wait for that particulartransaction state. The btrfs_blocked_trans_types[] array already defineswhich transaction types should wait for which transaction states, butthis check was missing in wait_current_trans().This can lead to a deadlock scenario involving two transactions andpending ordered extents: 1. Transaction A is in TRANS_STATE_COMMIT_DOING state 2. A worker processing an ordered extent calls start_transaction() with TRANS_JOIN 3. join_transaction() returns -EBUSY because Transaction A is in TRANS_STATE_COMMIT_DOING 4. Transaction A moves to TRANS_STATE_UNBLOCKED and completes 5. A new Transaction B is created (TRANS_STATE_RUNNING) 6. The ordered extent from step 2 is added to Transaction B's pending ordered extents 7. Transaction B immediately starts commit by another task and enters TRANS_STATE_COMMIT_START 8. The worker finally reaches wait_current_trans(), sees Transaction B in TRANS_STATE_COMMIT_START (a blocked state), and waits unconditionally 9. However, TRANS_JOIN should NOT wait for TRANS_STATE_COMMIT_START according to btrfs_blocked_trans_types[] 10. Transaction B is waiting for pending ordered extents to complete 11. Deadlock: Transaction B waits for ordered extent, ordered extent waits for Transaction BThis can be illustrated by the following call stacks: CPU0 CPU1 btrfs_finish_ordered_io() start_transaction(TRANS_JOIN) join_transaction() # -EBUSY (Transaction A is # TRANS_STATE_COMMIT_DOING) # Transaction A completes # Transaction B created # ordered extent added to # Transaction B's pending list btrfs_commit_transaction() # Transaction B enters # TRANS_STATE_COMMIT_START # waiting for pending ordered # extents wait_current_trans() # waits for Transaction B # (should not wait!)Task bstore_kv_sync in btrfs_commit_transaction waiting for orderedextents: __schedule+0x2e7/0x8a0 schedule+0x64/0xe0 btrfs_commit_transaction+0xbf7/0xda0 [btrfs] btrfs_sync_file+0x342/0x4d0 [btrfs] __x64_sys_fdatasync+0x4b/0x80 do_syscall_64+0x33/0x40 entry_SYSCALL_64_after_hwframe+0x44/0xa9Task kworker in wait_current_trans waiting for transaction commit: Workqueue: btrfs-syno_nocow btrfs_work_helper [btrfs] __schedule+0x2e7/0x8a0 schedule+0x64/0xe0 wait_current_trans+0xb0/0x110 [btrfs] start_transaction+0x346/0x5b0 [btrfs] btrfs_finish_ordered_io.isra.0+0x49b/0x9c0 [btrfs] btrfs_work_helper+0xe8/0x350 [btrfs] process_one_work+0x1d3/0x3c0 worker_thread+0x4d/0x3e0 kthread+0x12d/0x150 ret_from_fork+0x1f/0x30Fix this by passing the transaction type to wait_current_trans() andchecking btrfs_blocked_trans_types[cur_trans->state] against the giventype before deciding to wait.

These race conditions cancause the SCSI layer to fail to wake the error handler, leaving I/Othrough the SCSI host stuck as the error state cannot advance.First, there is an memory ordering issue within scsi_dec_host_busy().The write which clears SCMD_STATE_INFLIGHT may be reordered with readscounting in scsi_host_busy(). While the local CPU will see its ownwrite, reordering can allow other CPUs in scsi_dec_host_busy() orscsi_eh_inc_host_failed() to see a raised busy count, causing no CPU tosee a host busy equal to the host_failed count.This race condition can be prevented with a memory barrier on the errorpath to force the write to be visible before counting host busycommands.Second, there is a general ordering issue with scsi_eh_inc_host_failed(). Bycounting busy commands before incrementing host_failed, it can race with afinal command in scsi_dec_host_busy(), such that scsi_dec_host_busy() doesnot see host_failed incremented but scsi_eh_inc_host_failed() counts busycommands before SCMD_STATE_INFLIGHT is cleared by scsi_dec_host_busy(),resulting in neither waking the error handler task.This needs the call to scsi_host_busy() to be moved after host_failed isincremented to close the race condition.

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

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

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

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

CVE-2025-38170 Severity: Moderate CVSS3 score: 4.5

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 ]

If an ethtool command that accesses the rss lut isattempted immediately after reset, it will result in NULL ptrdereference.

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

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

CVE-2026-25934 Severity: Moderate CVSS3 score: 4.3

Description: go-git is a highly extensible git implementation library written in pure Go. Prior to 5.16.5, a vulnerability was discovered in go-git whereby data integrity values for .pack and .idx files were not properly verified. This resulted in go-git potentially consuming corrupted files, which would likely result in unexpected errors such as object not found. For context, clients fetch packfiles from upstream Git servers. Those files contain a checksum of their contents, so that clients can perform integrity checks before consuming it. The pack indexes (.idx) are generated locally by go-git, or the git cli, when new .pack files are received and processed. The integrity checks for both files were not being verified correctly. This vulnerability is fixed in 5.16.5.

CVE-2025-71079 Severity: Moderate CVSS3 score: 4.1

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

Description: A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk.

CVE-2025-37882 Severity: Moderate CVSS3 score: 3.6

Description: In the Linux kernel, the following vulnerability has been resolved:usb: xhci: Fix isochronous Ring Underrun/Overrun event handlingThe TRB pointer of these events points at enqueue at the time of erroroccurrence on xHCI 1.1+ HCs or it's NULL on older ones. By the time weare handling the event, a new TD may be queued at this ring position.I can trigger this race by rising interrupt moderation to increase IRQhandling delay. Similar delay may occur naturally due to system load.If this ever happens after a Missed Service Error, missed TDs will beskipped and the new TD processed as if it matched the event. It couldbe given back prematurely, risking data loss or buffer UAF by the xHC.Don't complete TDs on xrun events and don't warn if queued TDs don'tmatch the event's TRB pointer, which can be NULL or a link/no-op TRB.Don't warn if there are no queued TDs at all.Now that it's safe, also handle xrun events if the skip flag is clear.This ensures completion of any TD stuck in 'error mid TD' state rightbefore the xrun event, which could happen if a driver submits a finitenumber of URBs to a buggy HC and then an error occurs on the last TD.

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.

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.

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-2026-23032 Severity: Low CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:null_blk: fix kmemleak by releasing references to fault configfs itemsWhen CONFIG_BLK_DEV_NULL_BLK_FAULT_INJECTION is enabled, the null-blkdriver sets up fault injection support by creating the timeout_inject,requeue_inject, and init_hctx_fault_inject configfs items as childrenof the top-level nullbX configfs group.However, when the nullbX device is removed, the references taken tothese fault-config configfs items are not released. As a result,kmemleak reports a memory leak, for example:unreferenced object 0xc00000021ff25c40 (size 32): comm "mkdir", pid 10665, jiffies 4322121578 hex dump (first 32 bytes): 69 6e 69 74 5f 68 63 74 78 5f 66 61 75 6c 74 5f init_hctx_fault_ 69 6e 6a 65 63 74 00 88 00 00 00 00 00 00 00 00 inject.......... backtrace (crc 1a018c86): __kmalloc_node_track_caller_noprof+0x494/0xbd8 kvasprintf+0x74/0xf4 config_item_set_name+0xf0/0x104 config_group_init_type_name+0x48/0xfc fault_config_init+0x48/0xf0 0xc0080000180559e4 configfs_mkdir+0x304/0x814 vfs_mkdir+0x49c/0x604 do_mkdirat+0x314/0x3d0 sys_mkdir+0xa0/0xd8 system_call_exception+0x1b0/0x4f0 system_call_vectored_common+0x15c/0x2ecFix this by explicitly releasing the references to the fault-configconfigfs items when dropping the reference to the top-level nullbXconfigfs group.

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.
