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

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

CVE-2025-45582 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-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-2025-27144 Severity: Important CVSS3 score: 7.5

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

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: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Prior to 1.6.52, an out-of-bounds read vulnerability in libpng's simplified API allows reading up to 1012 bytes beyond the png_sRGB_base[512] array when processing valid palette PNG images with partial transparency and gamma correction. The PNG files that trigger this vulnerability are valid per the PNG specification; the bug is in libpng's internal state management. Upgrade to libpng 1.6.52 or later.

Trawling through the disassembly, you cansee that the complaint is from the access in bt_dev_dbg() under theHCI_ADV_MONITOR_EXT_MSFT case. The problem case happens becausemsft_remove_monitor() can end up freeing the monitorstructure. Specifically: hci_remove_adv_monitor() -> msft_remove_monitor() -> msft_remove_monitor_sync() -> msft_le_cancel_monitor_advertisement_cb() -> hci_free_adv_monitor()Let's fix the problem by just stashing the relevant data when it'sstill valid.

A reference on the task_struct is not neededbecause requeue_pi_wake_futex() is invoked with a spinlock_t held whichimplies a RCU read section.Even if T1 terminates immediately after, the task_struct will remain validduring T2's wake_up_state().

Both scenarios can then pass thevalidation successfully.This doesn't happen with valid XSk applications, but can be usedto perform attacks.Always promote desc->len to ``u64`` first to exclude positiveoverflows of it.

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

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

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

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

This avoids deadlock.dma-fence_ops::signaled can be called with the fence lock in unknownstate. For radeon, the fence lock is also the wait queue lock. This cancause a self deadlock when signaled() tries to make forward progress onthe wait queue. But advancing the queue is unneeded because incorrectlyreturning false from signaled() is perfectly acceptable.(cherry picked from commit 527ba26e50ec2ca2be9c7c82f3ad42998a75d0db)

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.

This avoids a possible out-of-bounds access on the pivotarray if the write extends to the last slot in the node, in which case thenode maximum should be used as the end pivot.akpm: this doesn't affect any current callers, but new users of mapletreemay encounter this problem if backported into earlier kernels, so let'sfix it in -stable kernels in case of this.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: ath9k: avoid referencing uninit memory in ath9k_wmi_ctrl_rxFor the reasons also described in commit b383e8abed41 ("wifi: ath9k: avoiduninit memory read in ath9k_htc_rx_msg()"), ath9k_htc_rx_msg() shouldvalidate pkt_len before accessing the SKB.For example, the obtained SKB may have been badly constructed withpkt_len = 8. In this case, the SKB can only contain a valid htc_frame_hdrbut after being processed in ath9k_htc_rx_msg() and passed toath9k_wmi_ctrl_rx() endpoint RX handler, it is expected to have a WMIcommand header which should be located inside its data payload.Implement sanity checking inside ath9k_wmi_ctrl_rx(). Otherwise, uninitmemory can be referenced.Tested on Qualcomm Atheros Communications AR9271 802.11n .Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

CVE-2025-40219 Severity: Moderate CVSS3 score: 6.6

Description: In the Linux kernel, the following vulnerability has been resolved:PCI/IOV: Add PCI rescan-remove locking when enabling/disabling SR-IOVBefore disabling SR-IOV via config space accesses to the parent PF,sriov_disable() first removes the PCI devices representing the VFs.Since commit 9d16947b7583 ("PCI: Add global pci_lock_rescan_remove()")such removal operations are serialized against concurrent remove andrescan using the pci_rescan_remove_lock. No such locking was ever addedin sriov_disable() however. In particular when commit 18f9e9d150fc("PCI/IOV: Factor out sriov_add_vfs()") factored out the PCI deviceremoval into sriov_del_vfs() there was still no locking around thepci_iov_remove_virtfn() calls.On s390 the lack of serialization in sriov_disable() may cause doubleremove and list corruption with the below (amended) trace being observed: PSW: 0704c00180000000 0000000c914e4b38 (klist_put+56) GPRS: 000003800313fb48 0000000000000000 0000000100000001 0000000000000001 00000000f9b520a8 0000000000000000 0000000000002fbd 00000000f4cc9480 0000000000000001 0000000000000000 0000000000000000 0000000180692828 00000000818e8000 000003800313fe2c 000003800313fb20 000003800313fad8 #0 [3800313fb20] device_del at c9158ad5c #1 [3800313fb88] pci_remove_bus_device at c915105ba #2 [3800313fbd0] pci_iov_remove_virtfn at c9152f198 #3 [3800313fc28] zpci_iov_remove_virtfn at c90fb67c0 #4 [3800313fc60] zpci_bus_remove_device at c90fb6104 #5 [3800313fca0] __zpci_event_availability at c90fb3dca #6 [3800313fd08] chsc_process_sei_nt0 at c918fe4a2 #7 [3800313fd60] crw_collect_info at c91905822 #8 [3800313fe10] kthread at c90feb390 #9 [3800313fe68] __ret_from_fork at c90f6aa64 #10 [3800313fe98] ret_from_fork at c9194f3f2.This is because in addition to sriov_disable() removing the VFs, theplatform also generates hot-unplug events for the VFs. This being thereverse operation to the hotplug events generated by sriov_enable() andhandled via pdev->no_vf_scan. And while the event processing takespci_rescan_remove_lock and checks whether the struct pci_dev still exists,the lack of synchronization makes this checking racy.Other races may also be possible of course though given that this lack oflocking persisted so long observable races seem very rare. Even on s390 thelist corruption was only observed with certain devices since the platformevents are only triggered by config accesses after the removal, so as longas the removal finished synchronously they would not race. Either way thelocking is missing so fix this by adding it to the sriov_del_vfs() helper.Just like PCI rescan-remove, locking is also missing in sriov_add_vfs()including for the error case where pci_stop_and_remove_bus_device() iscalled without the PCI rescan-remove lock being held. Even in the non-errorcase, adding new PCI devices and buses should be serialized via the PCIrescan-remove lock. Add the necessary locking.

Description: In the Linux kernel, the following vulnerability has been resolved:team: Move team device type change at the end of team_port_addAttempting to add a port device that is already up will expectedly fail,but not before modifying the team device header_ops.In the case of the syzbot reproducer the gre0 device isalready in state UP when it attempts to add it as aport device of team0, this fails but before thatheader_ops->create of team0 is changed from eth_header to ipgre_headerin the call to team_dev_type_check_change.Later when we end up in ipgre_header() struct ip_tunnel* points to nonsenseas the private data of the device still holds a struct team.Example sequence of iproute2 commands to reproduce the hang/BUG():ip link add dev team0 type teamip link add dev gre0 type greip link set dev gre0 upip link set dev gre0 master team0ip link set dev team0 upping -I team0 1.1.1.1Move team_dev_type_check_change down where all other checks have passedas it changes the dev type with no way to restore it in caseone of the checks that follow it fail.Also make sure to preserve the origial mtu assignment: - If port_dev is not the same type as dev, dev takes mtu from port_dev - If port_dev is the same type as dev, port_dev takes mtu from devThis is done by adding a conditional before the call to dev_set_mtuto prevent it from assigning port_dev->mtu = dev->mtu and insteadletting team_dev_type_check_change assign dev->mtu = port_dev->mtu.The conditional is needed because the patch moves the call toteam_dev_type_check_change past dev_set_mtu.Testing: - team device driver in-tree selftests - Add/remove various devices as slaves of team device - syzbot

Description: In the Linux kernel, the following vulnerability has been resolved:usb: potential integer overflow in usbg_make_tpg()The variable tpgt in usbg_make_tpg() is defined as unsigned long and isassigned to tpgt->tport_tpgt, which is defined as u16. This may cause aninteger overflow when tpgt is greater than USHRT_MAX (65535). Ihaven't tried to trigger it myself, but it is possible to trigger itby calling usbg_make_tpg() with a large value for tpgt.I modified the type of tpgt to match tpgt->tport_tpgt and adjusted therelevant code accordingly.This patch is similar to commit 59c816c1f24d ("vhost/scsi: potentialmemory corruption").

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.

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5e: Move representor neigh cleanup to profile cleanup_txFor IP tunnel encapsulation in ECMP (Equal-Cost Multipath) mode, asthe flow is duplicated to the peer eswitch, the related neighbourinformation on the peer uplink representor is created as well.In the cited commit, eswitch devcom unpair is moved to uplink unloadAPI, specifically the profile->cleanup_tx. If there is a encap ruleoffloaded in ECMP mode, when one eswitch does unpair (because ofunloading the driver, for instance), and the peer rule from the peereswitch is going to be deleted, the use-after-free error is triggeredwhile accessing neigh info, as it is already cleaned up in uplink'sprofile->disable, which is before its profile->cleanup_tx.To fix this issue, move the neigh cleanup to profile's cleanup_txcallback, and after mlx5e_cleanup_uplink_rep_tx is called. The neighinit is moved to init_tx for symmeter.[ 2453.376299] BUG: KASAN: slab-use-after-free in mlx5e_rep_neigh_entry_release+0x109/0x3a0 [mlx5_core][ 2453.379125] Read of size 4 at addr ffff888127af9008 by task modprobe/2496[ 2453.381542] CPU: 7 PID: 2496 Comm: modprobe Tainted: G B 6.4.0-rc7+ #15[ 2453.383386] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014[ 2453.384335] Call Trace:[ 2453.384625] [ 2453.384891] dump_stack_lvl+0x33/0x50[ 2453.385285] print_report+0xc2/0x610[ 2453.385667] ? __virt_addr_valid+0xb1/0x130[ 2453.386091] ? mlx5e_rep_neigh_entry_release+0x109/0x3a0 [mlx5_core][ 2453.386757] kasan_report+0xae/0xe0[ 2453.387123] ? mlx5e_rep_neigh_entry_release+0x109/0x3a0 [mlx5_core][ 2453.387798] mlx5e_rep_neigh_entry_release+0x109/0x3a0 [mlx5_core][ 2453.388465] mlx5e_rep_encap_entry_detach+0xa6/0xe0 [mlx5_core][ 2453.389111] mlx5e_encap_dealloc+0xa7/0x100 [mlx5_core][ 2453.389706] mlx5e_tc_tun_encap_dests_unset+0x61/0xb0 [mlx5_core][ 2453.390361] mlx5_free_flow_attr_actions+0x11e/0x340 [mlx5_core][ 2453.391015] ? complete_all+0x43/0xd0[ 2453.391398] ? free_flow_post_acts+0x38/0x120 [mlx5_core][ 2453.392004] mlx5e_tc_del_fdb_flow+0x4ae/0x690 [mlx5_core][ 2453.392618] mlx5e_tc_del_fdb_peers_flow+0x308/0x370 [mlx5_core][ 2453.393276] mlx5e_tc_clean_fdb_peer_flows+0xf5/0x140 [mlx5_core][ 2453.393925] mlx5_esw_offloads_unpair+0x86/0x540 [mlx5_core][ 2453.394546] ? mlx5_esw_offloads_set_ns_peer.isra.0+0x180/0x180 [mlx5_core][ 2453.395268] ? down_write+0xaa/0x100[ 2453.395652] mlx5_esw_offloads_devcom_event+0x203/0x530 [mlx5_core][ 2453.396317] mlx5_devcom_send_event+0xbb/0x190 [mlx5_core][ 2453.396917] mlx5_esw_offloads_devcom_cleanup+0xb0/0xd0 [mlx5_core][ 2453.397582] mlx5e_tc_esw_cleanup+0x42/0x120 [mlx5_core][ 2453.398182] mlx5e_rep_tc_cleanup+0x15/0x30 [mlx5_core][ 2453.398768] mlx5e_cleanup_rep_tx+0x6c/0x80 [mlx5_core][ 2453.399367] mlx5e_detach_netdev+0xee/0x120 [mlx5_core][ 2453.399957] mlx5e_netdev_change_profile+0x84/0x170 [mlx5_core][ 2453.400598] mlx5e_vport_rep_unload+0xe0/0xf0 [mlx5_core][ 2453.403781] mlx5_eswitch_unregister_vport_reps+0x15e/0x190 [mlx5_core][ 2453.404479] ? mlx5_eswitch_register_vport_reps+0x200/0x200 [mlx5_core][ 2453.405170] ? up_write+0x39/0x60[ 2453.405529] ? kernfs_remove_by_name_ns+0xb7/0xe0[ 2453.405985] auxiliary_bus_remove+0x2e/0x40[ 2453.406405] device_release_driver_internal+0x243/0x2d0[ 2453.406900] ? kobject_put+0x42/0x2d0[ 2453.407284] bus_remove_device+0x128/0x1d0[ 2453.407687] device_del+0x240/0x550[ 2453.408053] ? waiting_for_supplier_show+0xe0/0xe0[ 2453.408511] ? kobject_put+0xfa/0x2d0[ 2453.408889] ? __kmem_cache_free+0x14d/0x280[ 2453.409310] mlx5_rescan_drivers_locked.part.0+0xcd/0x2b0 [mlx5_core][ 2453.409973] mlx5_unregister_device+0x40/0x50 [mlx5_core][ 2453.410561] mlx5_uninit_one+0x3d/0x110 [mlx5_core][ 2453.411111] remove_one+0x89/0x130 [mlx5_core][ 24---truncated---

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

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

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

As aresult a domain can still have access any 64bit memory BAR when suchdevice is no longer assigned to the domain.For PV domains the permission leak allows the domain itself to map the memoryin the page-tables. For HVM it would require a compromised device model orstubdomain to map the leaked memory into the HVM domain p2m.

CVE-2025-71096 Severity: Moderate CVSS3 score: 6.5

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/core: Check for the presence of LS_NLA_TYPE_DGID correctlyThe netlink response for RDMA_NL_LS_OP_IP_RESOLVE should always have aLS_NLA_TYPE_DGID attribute, it is invalid if it does not.Use the nl parsing logic properly and call nla_parse_deprecated() to fillthe nlattrs array and then directly index that array to get the data forthe DGID. Just fail if it is NULL.Remove the for loop searching for the nla, and squash the validation andparsing into one function.Fixes an uninitialized read from the stack triggered by userspace if itdoes not provide the DGID to a kernel initiated RDMA_NL_LS_OP_IP_RESOLVEquery.

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-2026-24401 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.

This leadsto UAF issues during subsequent accesses. Here's an example of reproductionsteps:1. With /dev/fb0 already registered in the system, load a kernel module to register a new device /dev/fb1;2. Set fb1's mode to the global fb_display[] array (via FBIOPUT_CON2FBMAP);3. Switch console from fb to VGA (to allow normal rmmod of the ko);4. Unload the kernel module, at this point fb1's modelist is freed, leaving a wild pointer in fb_display[];5. Trigger the bug via system calls through fb0 attempting to delete a mode from fb0.Add a check in do_unregister_framebuffer(): if the mode to be freed existsin fb_display[], set the corresponding mode pointer to NULL.

CVE-2025-40343 Severity: Moderate CVSS3 score: 6.4

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

CVE-2023-54096 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:soundwire: fix enumeration completionThe soundwire subsystem uses two completion structures that allowdrivers to wait for soundwire device to become enumerated on the bus andinitialised by their drivers, respectively.The code implementing the signalling is currently broken as it does notsignal all current and future waiters and also uses the wrongreinitialisation function, which can potentially lead to memorycorruption if there are still waiters on the queue.Not signalling future waiters specifically breaks sound card probedeferrals as codec drivers can not tell that the soundwire device isalready attached when being reprobed. Some codec runtime PMimplementations suffer from similar problems as waiting for enumerationduring resume can also timeout despite the device already having beenenumerated.

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

CVE-2025-68331 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:usb: uas: fix urb unmapping issue when the uas device is remove during ongoing data transferWhen a UAS device is unplugged during data transfer, there isa probability of a system panic occurring. The root cause isan access to an invalid memory address during URB callback handling.Specifically, this happens when the dma_direct_unmap_sg() functionis called within the usb_hcd_unmap_urb_for_dma() interface, but thesg->dma_address field is 0 and the sg data structure has already beenfreed.The SCSI driver sends transfer commands by invoking uas_queuecommand_lck()in uas.c, using the uas_submit_urbs() function to submit requests to USB.Within the uas_submit_urbs() implementation, three URBs (sense_urb,data_urb, and cmd_urb) are sequentially submitted. Device removal mayoccur at any point during uas_submit_urbs execution, which may resultin URB submission failure. However, some URBs might have been successfullysubmitted before the failure, and uas_submit_urbs will return the -ENODEVerror code in this case. The current error handling directly callsscsi_done(). In the SCSI driver, this eventually triggers scsi_complete()to invoke scsi_end_request() for releasing the sgtable. The successfullysubmitted URBs, when being unlinked to giveback, callusb_hcd_unmap_urb_for_dma() in hcd.c, leading to exceptions during sgunmapping operations since the sg data structure has already been freed.This patch modifies the error condition check in the uas_submit_urbs()function. When a UAS device is removed but one or more URBs have alreadybeen successfully submitted to USB, it avoids immediately invokingscsi_done() and save the cmnd to devinfo->cmnd array. If the successfullysubmitted URBs is completed before devinfo->resetting being set, thenthe scsi_done() function will be called within uas_try_complete() afterall pending URB operations are finalized. Otherwise, the scsi_done()function will be called within uas_zap_pending(), which is executed afterusb_kill_anchored_urbs().The error handling only takes effect when uas_queuecommand_lck() callsuas_submit_urbs() and returns the error value -ENODEV . In this case,the device is disconnected, and the flow proceeds to uas_disconnect(),where uas_zap_pending() is invoked to call uas_try_complete().

CVE-2025-68339 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:atm/fore200e: Fix possible data race in fore200e_open()Protect access to fore200e->available_cell_rate with rate_mtx lock in theerror handling path of fore200e_open() to prevent a data race.The field fore200e->available_cell_rate is a shared resource used to trackavailable bandwidth. It is concurrently accessed by fore200e_open(),fore200e_close(), and fore200e_change_qos().In fore200e_open(), the lock rate_mtx is correctly held when subtractingvcc->qos.txtp.max_pcr from available_cell_rate to reserve bandwidth.However, if the subsequent call to fore200e_activate_vcin() fails, thefunction restores the reserved bandwidth by adding back toavailable_cell_rate without holding the lock.This introduces a race condition because available_cell_rate is a globaldevice resource shared across all VCCs. If the error path infore200e_open() executes concurrently with operations likefore200e_close() or fore200e_change_qos() on other VCCs, aread-modify-write race occurs.Specifically, the error path reads the rate without the lock. If anotherCPU acquires the lock and modifies the rate (e.g., releasing bandwidth infore200e_close()) between this read and the subsequent write, the errorpath will overwrite the concurrent update with a stale value. This resultsin incorrect bandwidth accounting.

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.

Holding the net device's underlying kobject isn't actually of much help, it just prevents it from being freed (but we never need that kobject directly). What helps us to prevent the net device from being unregistered is the parallel netdev reference mechanism (dev_hold() and dev_put()).Actually we actually use that netdev tracker mechanism implicitly onuser ports since commit 2f1e8ea726e9 ("net: dsa: link interfaces withthe DSA master to get rid of lockdep warnings"), via netdev_upper_dev_link().But time still passes at DSA switch probe time between the initialof_find_net_device_by_node() code and the user port creation time, timeduring which the conduit could unregister itself and DSA wouldn't knowabout it.So we have to run of_find_net_device_by_node() under rtnl_lock() toprevent that from happening, and release the lock only with the netdevtracker having acquired the reference.Do we need to keep the reference until dsa_unregister_switch() /dsa_switch_shutdown()?1: Maybe yes. A switch device will still be registered even if all user ports failed to probe, see commit 86f8b1c01a0a ("net: dsa: Do not make user port errors fatal"), and the cpu_dp->conduit pointers remain valid. I haven't audited all call paths to see whether they will actually use the conduit in lack of any user port, but if they do, it seems safer to not rely on user ports for that reference.2. Definitely yes. We support changing the conduit which a user port is associated to, and we can get into a situation where we've moved all user ports away from a conduit, thus no longer hold any reference to it via the net device tracker. But we shouldn't let it go nonetheless - see the next change in relation to dsa_tree_find_first_conduit() and LAG conduits which disappear. We have to be prepared to return to the physical conduit, so the CPU port must explicitly keep another reference to it. This is also to say: the user ports and their CPU ports may not always keep a reference to the same conduit net device, and both are needed.As for the conduit's kobject for the /sys/class/net/ entry, we don'tcare about it, we can release it as soon as we hold the net deviceobject itself.History and blame attribution-----------------------------The code has been refactored so many times, it is very difficult tofollow and properly attribute a blame, but I'll try to make a shorthistory which I hope to be correct.We have two distinct probing paths:- one for OF, introduced in 2016 i---truncated---

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

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

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

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

Description: Issue summary: Processing a malformed PKCS#12 file can trigger a NULL pointerdereference in the PKCS12_item_decrypt_d2i_ex() function.Impact summary: A NULL pointer dereference can trigger a crash which leads toDenial of Service for an application processing PKCS#12 files.The PKCS12_item_decrypt_d2i_ex() function does not check whether the octparameter is NULL before dereferencing it. When called fromPKCS12_unpack_p7encdata() with a malformed PKCS#12 file, this parameter canbe NULL, causing a crash.

Description: Issue summary: An invalid or NULL pointer dereference can happen inan application processing a malformed PKCS#12 file.Impact summary: An application processing a malformed PKCS#12 file can becaused to dereference an invalid or NULL pointer on memory read, resultingin a Denial of Service.A type confusion vulnerability exists in PKCS#12 parsing code wherean ASN1_TYPE union member is accessed without first validating the type,causing an invalid pointer read.The location is constrained to a 1-byte address space, meaning anyattempted pointer manipulation can only target addresses between 0x00 and 0xFF.This range corresponds to the zero page, which is unmapped on most modernoperating systems and will reliably result in a crash, leading only to aDenial of Service. Exploiting this issue also requires a user or applicationto process a maliciously crafted PKCS#12 file. It is uncommon to acceptuntrusted PKCS#12 files in applications as they are usually used to storeprivate keys which are trusted by definition.

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:ima: don't clear IMA_DIGSIG flag when setting or removing non-IMA xattrCurrently when both IMA and EVM are in fix mode, the IMA signature willbe reset to IMA hash if a program first stores IMA signature insecurity.ima and then writes/removes some other security xattr for thefile.For example, on Fedora, after booting the kernel with "ima_appraise=fixevm=fix ima_policy=appraise_tcb" and installing rpm-plugin-ima,installing/reinstalling a package will not make good reference IMAsignature generated. Instead IMA hash is generated, # getfattr -m - -d -e hex /usr/bin/bash # file: usr/bin/bash security.ima=0x0404...This happens because when setting security.selinux, the IMA_DIGSIG flagthat had been set early was cleared. As a result, IMA hash is generatedwhen the file is closed.Similarly, IMA signature can be cleared on file close after removingsecurity xattr like security.evm or setting/removing ACL.Prevent replacing the IMA file signature with a file hash, by preventingthe IMA_DIGSIG flag from being reset.Here's a minimal C reproducer which sets security.selinux as the laststep which can also replaced by removing security.evm or setting ACL, #include #include #include #include #include #include int main() { const char* file_path = "/usr/sbin/test_binary"; const char* hex_string = "030204d33204490066306402304"; int length = strlen(hex_string); char* ima_attr_value; int fd; fd = open(file_path, O_WRONLY|O_CREAT|O_EXCL, 0644); if (fd == -1) { perror("Error opening file"); return 1; } ima_attr_value = (char*)malloc(length / 2 ); for (int i = 0, j = 0; i < length; i += 2, j++) { sscanf(hex_string + i, "%2hhx", &ima_attr_value[j]); } if (fsetxattr(fd, "security.ima", ima_attr_value, length/2, 0) == -1) { perror("Error setting extended attribute"); close(fd); return 1; } const char* selinux_value= "system_u:object_r:bin_t:s0"; if (fsetxattr(fd, "security.selinux", selinux_value, strlen(selinux_value), 0) == -1) { perror("Error setting extended attribute"); close(fd); return 1; } close(fd); return 0; }

It creates instead a link where thesupplier is the parent of the expected device.One consequence is that removal order is not correctly enforced.Issues happen for example with the following sections in a device treeoverlay: // An LED driver chip pca9632@62 { compatible = "nxp,pca9632"; reg = <0x62>; // ... addon_led_pwm: led-pwm@3 { reg = <3>; label = "addon:led:pwm"; }; }; backlight-addon { compatible = "led-backlight"; leds = <&addon_led_pwm>; brightness-levels = <255>; default-brightness-level = <255>; };In this example, the devlink should be created between the backlight-addon(consumer) and the pca9632@62 (supplier). Instead it is created between thebacklight-addon (consumer) and the parent of the pca9632@62, which istypically the I2C bus adapter.On removal of the above overlay, the LED driver can be removed before thebacklight device, resulting in: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000010 ... Call trace: led_put+0xe0/0x140 devm_led_release+0x6c/0x98Another way to reproduce the bug without any device tree overlays isunbinding the LED class device (pca9632@62) before unbinding the consumer(backlight-addon): echo 11-0062 >/sys/bus/i2c/drivers/leds-pca963x/unbind echo ...backlight-dock >/sys/bus/platform/drivers/led-backlight/unbindFix by adding a devlink between the consuming led-backlight device and thesupplying LED device, as other drivers and subsystems do as well.

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---

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

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

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

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

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().

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

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

[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-2023-54149 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:net: dsa: avoid suspicious RCU usage for synced VLAN-aware MAC addressesWhen using the felix driver (the only one which supports UC filteringand MC filtering) as a DSA master for a random other DSA switch, one cansee the following stack trace when the downstream switch ports join aVLAN-aware bridge:=============================WARNING: suspicious RCU usage-----------------------------net/8021q/vlan_core.c:238 suspicious rcu_dereference_protected() usage!stack backtrace:Workqueue: dsa_ordered dsa_slave_switchdev_event_workCall trace: lockdep_rcu_suspicious+0x170/0x210 vlan_for_each+0x8c/0x188 dsa_slave_sync_uc+0x128/0x178 __hw_addr_sync_dev+0x138/0x158 dsa_slave_set_rx_mode+0x58/0x70 __dev_set_rx_mode+0x88/0xa8 dev_uc_add+0x74/0xa0 dsa_port_bridge_host_fdb_add+0xec/0x180 dsa_slave_switchdev_event_work+0x7c/0x1c8 process_one_work+0x290/0x568What it's saying is that vlan_for_each() expects rtnl_lock() context andit's not getting it, when it's called from the DSA master's ndo_set_rx_mode().The caller of that - dsa_slave_set_rx_mode() - is the slave DSAinterface's dsa_port_bridge_host_fdb_add() which comes from the deferreddsa_slave_switchdev_event_work().We went to great lengths to avoid the rtnl_lock() context in that callpath in commit 0faf890fc519 ("net: dsa: drop rtnl_lock fromdsa_slave_switchdev_event_work"), and calling rtnl_lock() is simply notan option due to the possibility of deadlocking when callingdsa_flush_workqueue() from the call paths that do hold rtnl_lock() -basically all of them.So, when the DSA master calls vlan_for_each() from its ndo_set_rx_mode(),the state of the 8021q driver on this device is really not protectedfrom concurrent access by anything.Looking at net/8021q/, I don't think that vlan_info->vid_list wasparticularly designed with RCU traversal in mind, so introducing an RCUread-side form of vlan_for_each() - vlan_for_each_rcu() - won't be soeasy, and it also wouldn't be exactly what we need anyway.In general I believe that the solution isn't in net/8021q/ anyway;vlan_for_each() is not cut out for this task. DSA doesn't need rtnl_lock()to be held per se - since it's not a netdev state change that we'reblocking, but rather, just concurrent additions/removals to a VLAN list.We don't even need sleepable context - the callback of vlan_for_each()just schedules deferred work.The proposed escape is to remove the dependency on vlan_for_each() andto open-code a non-sleepable, rtnl-free alternative to that, based oncopies of the VLAN list modified from .ndo_vlan_rx_add_vid() and.ndo_vlan_rx_kill_vid().

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/efa: Fix wrong resources deallocation orderWhen trying to destroy QP or CQ, we first decrease the refcount andpotentially free memory regions allocated for the object and thenrequest the device to destroy the object. If the device fails, theobject isn't fully destroyed so the user/IB core can try to destroy theobject again which will lead to underflow when trying to decrease analready zeroed refcount.Deallocate resources in reverse order of allocating them to safely freethem.

Description: In the Linux kernel, the following vulnerability has been resolved:HID: uclogic: Correct devm device reference for hidinput input_dev nameReference the HID device rather than the input device for the devmallocation of the input_dev name. Referencing the input_dev would lead to ause-after-free when the input_dev was unregistered and subsequently fires auevent that depends on the name. At the point of firing the uevent, thename would be freed by devres management.Use devm_kasprintf to simplify the logic for allocating memory andformatting the input_dev name string.

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

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

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

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

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

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

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

CVE-2023-53768 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:regmap-irq: Fix out-of-bounds access when allocating config buffersWhen allocating the 2D array for handling IRQ type registers inregmap_add_irq_chip_fwnode(), the intent is to allocate a matrixwith num_config_bases rows and num_config_regs columns.This is currently handled by allocating a buffer to hold a pointer foreach row (i.e. num_config_bases). After that, the logic attempts toallocate the memory required to hold the register configuration foreach row. However, instead of doing this allocation for each row(i.e. num_config_bases allocations), the logic erroneously does thisallocation num_config_regs number of times.This scenario can lead to out-of-bounds accesses when num_config_regsis greater than num_config_bases. Fix this by updating the terminatingcondition of the loop that allocates the memory for holding the registerconfiguration to allocate memory only for each row in the matrix.Amit Pundir reported a crash that was occurring on his db845c devicedue to memory corruption (see "Closes" tag for Amit's report).

Description: In the Linux kernel, the following vulnerability has been resolved:accel/qaic: Clean up integer overflow checking in map_user_pages()The encode_dma() function has some validation on in_trans->size but itwould be more clear to move those checks to find_and_map_user_pages().The encode_dma() had two checks: if (in_trans->addr + in_trans->size < in_trans->addr || !in_trans->size) return -EINVAL;The in_trans->addr variable is the starting address. The in_trans->sizevariable is the total size of the transfer. The transfer can occur inparts and the resources->xferred_dma_size tracks how many bytes we havealready transferred.This patch introduces a new variable "remaining" which represents theamount we want to transfer (in_trans->size) minus the amount we havealready transferred (resources->xferred_dma_size).I have modified the check for if in_trans->size is zero to instead checkif in_trans->size is less than resources->xferred_dma_size. If we havealready transferred more bytes than in_trans->size then there are negativebytes remaining which doesn't make sense. If there are zero bytesremaining to be copied, just return success.The check in encode_dma() checked that "addr + size" could not overflowand barring a driver bug that should work, but it's easier to check ifwe do this in parts. First check that "in_trans->addr +resources->xferred_dma_size" is safe. Then check that "xfer_start_addr +remaining" is safe.My final concern was that we are dealing with u64 values but on 32bitsystems the kmalloc() function will truncate the sizes to 32 bits. SoI calculated "total = in_trans->size + offset_in_page(xfer_start_addr);"and returned -EINVAL if it were >= SIZE_MAX. This will not affect 64bitsystems.

Blindly prepending bytes to an skb is always wrong.This commit introduces a call to skb_cow_head() before the call tomt7921_usb_sdio_write_txwi() in mt7921_usb_sdio_tx_prepare_skb() toensure that at least MT_SDIO_TXD_SIZE + MT_SDIO_HDR_SIZE bytes can bepushed onto the skb.Without this fix, I can trivially cause kernel panics by bridging anMT7921AU-based USB 802.11ax interface with an Ethernet interface on anIntel Atom-based x86 system using its onboard RTL8169 PCI Ethernetadapter and also on an ARM-based Raspberry Pi 1 using its onboardSMSC9512 USB Ethernet adapter. Note that the panics do not occur inevery system configuration, as they occur only if the receiving netdevleaves less headroom in its received skbs than the mt7921 needs for itsSDIO headers.Here is an example stack trace of this panic on Raspberry Pi OS Lite2023-02-21 running kernel 6.1.24+ [1]: skb_panic from skb_push+0x44/0x48 skb_push from mt7921_usb_sdio_tx_prepare_skb+0xd4/0x190 [mt7921_common] mt7921_usb_sdio_tx_prepare_skb [mt7921_common] from mt76u_tx_queue_skb+0x94/0x1d0 [mt76_usb] mt76u_tx_queue_skb [mt76_usb] from __mt76_tx_queue_skb+0x4c/0xc8 [mt76] __mt76_tx_queue_skb [mt76] from mt76_txq_schedule.part.0+0x13c/0x398 [mt76] mt76_txq_schedule.part.0 [mt76] from mt76_txq_schedule_all+0x24/0x30 [mt76] mt76_txq_schedule_all [mt76] from mt7921_tx_worker+0x58/0xf4 [mt7921_common] mt7921_tx_worker [mt7921_common] from __mt76_worker_fn+0x9c/0xec [mt76] __mt76_worker_fn [mt76] from kthread+0xbc/0xe0 kthread from ret_from_fork+0x14/0x34After this fix, bridging the mt7921 interface works fine on both of mypreviously problematic systems.[1] https://github.com/raspberrypi/firmware/tree/5c276f55a4b21345cd4d6200a504ee991851ff7a

Instead use the xa_lock to serialize everything. The refcountcheck == 1 and xa_erase can be done under a single critical region. Thisavoids the need for any refcount incrementing.It has the downside that if userspace races destroy with other operationsit will get an EBUSY instead of waiting, but this is kind of racing isalready dangerous.

The int type does not offerenough space to store these values, and attempting to use it is arecipe for problems. In this particular case, overflows would occurwhen calculating/storing timestamps leading to incorrect values beingreported to userspace. In some cases these bad timestamps cause inputhandling in userspace to appear hung.

CVE-2023-53813 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: fix rbtree traversal bug in ext4_mb_use_preallocatedDuring allocations, while looking for preallocations(PA) in the perinode rbtree, we can't do a direct traversal of the tree becauseext4_mb_discard_group_preallocation() can paralelly mark the pa deletedand that can cause direct traversal to skip some entries. This wasleading to a BUG_ON() being hit [1] when we missed a PA that could satisfyour request and ultimately tried to create a new PA that would overlapwith the missed one.To makes sure we handle that case while still keeping the performance ofthe rbtree, we make use of the fact that the only pa that could possiblyoverlap the original goal start is the one that satisfies the belowconditions: 1. It must have it's logical start immediately to the left of (ie less than) original logical start. 2. It must not be deletedTo find this pa we use the following traversal method:1. Descend into the rbtree normally to find the immediate neighboringPA. Here we keep descending irrespective of if the PA is deleted or ifit overlaps with our request etc. The goal is to find an immediatelyadjacent PA.2. If the found PA is on right of original goal, use rb_prev() to findthe left adjacent PA.3. Check if this PA is deleted and keep moving left with rb_prev() untila non deleted PA is found.4. This is the PA we are looking for. Now we can check if it can satisfythe original request and proceed accordingly.This approach also takes care of having deleted PAs in the tree.(While we are at it, also fix a possible overflow bug in calculating theend of a PA)[1] https://lore.kernel.org/linux-ext4/CA+G9fYv2FRpLqBZf34ZinR8bU2_ZRAUOjKAD3+tKRFaEQHtt8Q@mail.gmail.com/

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:iio: adc: ina2xx: avoid NULL pointer dereference on OF device matchThe affected lines were resulting in a NULL pointer dereference on ourplatform because the device tree contained the following list ofcompatible strings: power-sensor@40 { compatible = "ti,ina232", "ti,ina231"; ... };Since the driver doesn't declare a compatible string "ti,ina232", the OFmatching succeeds on "ti,ina231". But the I2C device ID info ispopulated via the first compatible string, cf. modalias population inof_i2c_get_board_info(). Since there is no "ina232" entry in the legacyI2C device ID table either, the struct i2c_device_id *id pointer in theprobe function is NULL.Fix this by using the already populated type variable instead, whichpoints to the proper driver data. Since the name is also wanted, add ageneric one to the ina2xx_config table.

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

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

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

Whatshould happen if the transfer fails isn't entirely clear, but areasonably conservative approach is to pretend that no media ispresent.A similar problem exists in a usb_stor_dbg() call inalauda_get_media_status(). In this case, when an error occurs thecall is redundant, because usb_stor_ctrl_transfer() already will printa debugging message.Finally, unrelated to the uninitialized memory access, is the factthat alauda_check_media() performs DMA to a buffer on the stack.Fortunately usb-storage provides a general purpose DMA-able buffer foruses like this. We'll use it instead.

Description: In the Linux kernel, the following vulnerability has been resolved:md/raid5-cache: fix a deadlock in r5l_exit_log()Commit b13015af94cf ("md/raid5-cache: Clear conf->log after finishingwork") introduce a new problem:// caller hold reconfig_mutexr5l_exit_log flush_work(&log->disable_writeback_work) r5c_disable_writeback_async wait_event /* * conf->log is not NULL, and mddev_trylock() * will fail, wait_event() can never pass. */ conf->log = NULLFix this problem by setting 'config->log' to NULL before wake_up() as itused to be, so that wait_event() from r5c_disable_writeback_async() canexist. In the meantime, move forward md_unregister_thread() so thatnull-ptr-deref this commit fixed can still be fixed.

CVE-2023-53851 Severity: Moderate CVSS3 score: 5.5

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

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

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

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

Thisis not OK, as REQ_NOWAIT just means that we should not be sleepingwaiting on other IO, it does not mean that we can't potentiallyschedule.A simple test case demonstrates this quite nicely:int main(int argc, char *argv[]){ struct iovec iov; int fd; fd = open("/dev/dm-0", O_RDONLY | O_DIRECT); posix_memalign(&iov.iov_base, 4096, 4096); iov.iov_len = 4096; preadv2(fd, &iov, 1, 0, RWF_NOWAIT); return 0;}which will instantly spew:BUG: sleeping function called from invalid context at include/linux/sched/mm.h:306in_atomic(): 0, irqs_disabled(): 0, non_block: 0, pid: 5580, name: dm-nowaitpreempt_count: 0, expected: 0RCU nest depth: 1, expected: 0INFO: lockdep is turned off.CPU: 7 PID: 5580 Comm: dm-nowait Not tainted 6.6.0-rc1-g39956d2dcd81 #132Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.2-debian-1.16.2-1 04/01/2014Call Trace: dump_stack_lvl+0x11d/0x1b0 __might_resched+0x3c3/0x5e0 ? preempt_count_sub+0x150/0x150 mempool_alloc+0x1e2/0x390 ? mempool_resize+0x7d0/0x7d0 ? lock_sync+0x190/0x190 ? lock_release+0x4b7/0x670 ? internal_get_user_pages_fast+0x868/0x2d40 bio_alloc_bioset+0x417/0x8c0 ? bvec_alloc+0x200/0x200 ? internal_get_user_pages_fast+0xb8c/0x2d40 bio_alloc_clone+0x53/0x100 dm_submit_bio+0x27f/0x1a20 ? lock_release+0x4b7/0x670 ? blk_try_enter_queue+0x1a0/0x4d0 ? dm_dax_direct_access+0x260/0x260 ? rcu_is_watching+0x12/0xb0 ? blk_try_enter_queue+0x1cc/0x4d0 __submit_bio+0x239/0x310 ? __bio_queue_enter+0x700/0x700 ? kvm_clock_get_cycles+0x40/0x60 ? ktime_get+0x285/0x470 submit_bio_noacct_nocheck+0x4d9/0xb80 ? should_fail_request+0x80/0x80 ? preempt_count_sub+0x150/0x150 ? lock_release+0x4b7/0x670 ? __bio_add_page+0x143/0x2d0 ? iov_iter_revert+0x27/0x360 submit_bio_noacct+0x53e/0x1b30 submit_bio_wait+0x10a/0x230 ? submit_bio_wait_endio+0x40/0x40 __blkdev_direct_IO_simple+0x4f8/0x780 ? blkdev_bio_end_io+0x4c0/0x4c0 ? stack_trace_save+0x90/0xc0 ? __bio_clone+0x3c0/0x3c0 ? lock_release+0x4b7/0x670 ? lock_sync+0x190/0x190 ? atime_needs_update+0x3bf/0x7e0 ? timestamp_truncate+0x21b/0x2d0 ? inode_owner_or_capable+0x240/0x240 blkdev_direct_IO.part.0+0x84a/0x1810 ? rcu_is_watching+0x12/0xb0 ? lock_release+0x4b7/0x670 ? blkdev_read_iter+0x40d/0x530 ? reacquire_held_locks+0x4e0/0x4e0 ? __blkdev_direct_IO_simple+0x780/0x780 ? rcu_is_watching+0x12/0xb0 ? __mark_inode_dirty+0x297/0xd50 ? preempt_count_add+0x72/0x140 blkdev_read_iter+0x2a4/0x530 do_iter_readv_writev+0x2f2/0x3c0 ? generic_copy_file_range+0x1d0/0x1d0 ? fsnotify_perm.part.0+0x25d/0x630 ? security_file_permission+0xd8/0x100 do_iter_read+0x31b/0x880 ? import_iovec+0x10b/0x140 vfs_readv+0x12d/0x1a0 ? vfs_iter_read+0xb0/0xb0 ? rcu_is_watching+0x12/0xb0 ? rcu_is_watching+0x12/0xb0 ? lock_release+0x4b7/0x670 do_preadv+0x1b3/0x260 ? do_readv+0x370/0x370 __x64_sys_preadv2+0xef/0x150 do_syscall_64+0x39/0xb0 entry_SYSCALL_64_after_hwframe+0x63/0xcdRIP: 0033:0x7f5af41ad806Code: 41 54 41 89 fc 55 44 89 c5 53 48 89 cb 48 83 ec 18 80 3d e4 dd 0d 00 00 74 7a 45 89 c1 49 89 ca 45 31 c0 b8 47 01 00 00 0f 05 <48> 3d 00 f0 ff ff 0f 87 be 00 00 00 48 85 c0 79 4a 48 8b 0d da 55RSP: 002b:00007ffd3145c7f0 EFLAGS: 00000246 ORIG_RAX: 0000000000000147RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007f5af41ad806RDX: 0000000000000001 RSI: 00007ffd3145c850 RDI: 0000000000000003RBP: 0000000000000008 R08: 0000000000000000 R09: 0000000000000008R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000003R13: 00007ffd3145c850 R14: 000055f5f0431dd8 R15: 0000000000000001 where in fact it is---truncated---

CVE-2023-53989 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:arm64: mm: fix VA-range sanity checkBoth create_mapping_noalloc() and update_mapping_prot() sanity-checktheir 'virt' parameter, but the check itself doesn't make much sense.The condition used today appears to be a historical accident.The sanity-check condition: if ((virt >= PAGE_END) && (virt < VMALLOC_START)) { [ ... warning here ... ] return; }... can only be true for the KASAN shadow region or the module region,and there's no reason to exclude these specifically for creating andupdateing mappings.When arm64 support was first upstreamed in commit: c1cc1552616d0f35 ("arm64: MMU initialisation")... the condition was: if (virt < VMALLOC_START) { [ ... warning here ... ] return; }At the time, VMALLOC_START was the lowest kernel address, and this waschecking whether 'virt' would be translated via TTBR1.Subsequently in commit: 14c127c957c1c607 ("arm64: mm: Flip kernel VA space")... the condition was changed to: if ((virt >= VA_START) && (virt < VMALLOC_START)) { [ ... warning here ... ] return; }This appear to have been a thinko. The commit moved the linear map tothe bottom of the kernel address space, with VMALLOC_START being at thehalfway point. The old condition would warn for changes to the linearmap below this, and at the time VA_START was the end of the linear map.Subsequently we cleaned up the naming of VA_START in commit: 77ad4ce69321abbe ("arm64: memory: rename VA_START to PAGE_END")... keeping the erroneous condition as: if ((virt >= PAGE_END) && (virt < VMALLOC_START)) { [ ... warning here ... ] return; }Correct the condition to check against the start of the TTBR1 addressspace, which is currently PAGE_OFFSET. This simplifies the logic, andmore clearly matches the "outside kernel range" message in the warning.

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

CVE-2023-53999 Severity: Moderate CVSS3 score: 5.5

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

CVE-2023-54008 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:virtio_vdpa: build affinity masks conditionallyWe try to build affinity mask via create_affinity_masks()unconditionally which may lead several issues:- the affinity mask is not used for parent without affinity support (only VDUSE support the affinity now)- the logic of create_affinity_masks() might not work for devices other than block. For example it's not rare in the networking device where the number of queues could exceed the number of CPUs. Such case breaks the current affinity logic which is based on group_cpus_evenly() who assumes the number of CPUs are not less than the number of groups. This can trigger a warning[1]: if (ret >= 0) WARN_ON(nr_present + nr_others < numgrps);Fixing this by only build the affinity masks only when- Driver passes affinity descriptor, driver like virtio-blk can make sure to limit the number of queues when it exceeds the number of CPUs- Parent support affinity setting config opsThis help to avoid the warning. More optimizations could be done ontop.[1][ 682.146655] WARNING: CPU: 6 PID: 1550 at lib/group_cpus.c:400 group_cpus_evenly+0x1aa/0x1c0[ 682.146668] CPU: 6 PID: 1550 Comm: vdpa Not tainted 6.5.0-rc5jason+ #79[ 682.146671] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.2-0-gea1b7a073390-prebuilt.qemu.org 04/01/2014[ 682.146673] RIP: 0010:group_cpus_evenly+0x1aa/0x1c0[ 682.146676] Code: 4c 89 e0 5b 5d 41 5c 41 5d 41 5e c3 cc cc cc cc e8 1b c4 74 ff 48 89 ef e8 13 ac 98 ff 4c 89 e7 45 31 e4 e8 08 ac 98 ff eb c2 <0f> 0b eb b6 e8 fd 05 c3 00 45 31 e4 eb e5 cc cc cc cc cc cc cc cc[ 682.146679] RSP: 0018:ffffc9000215f498 EFLAGS: 00010293[ 682.146682] RAX: 000000000001f1e0 RBX: 0000000000000041 RCX: 0000000000000000[ 682.146684] RDX: ffff888109922058 RSI: 0000000000000041 RDI: 0000000000000030[ 682.146686] RBP: ffff888109922058 R08: ffffc9000215f498 R09: ffffc9000215f4a0[ 682.146687] R10: 00000000000198d0 R11: 0000000000000030 R12: ffff888107e02800[ 682.146689] R13: 0000000000000030 R14: 0000000000000030 R15: 0000000000000041[ 682.146692] FS: 00007fef52315740(0000) GS:ffff888237380000(0000) knlGS:0000000000000000[ 682.146695] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 682.146696] CR2: 00007fef52509000 CR3: 0000000110dbc004 CR4: 0000000000370ee0[ 682.146698] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 682.146700] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[ 682.146701] Call Trace:[ 682.146703] [ 682.146705] ? __warn+0x7b/0x130[ 682.146709] ? group_cpus_evenly+0x1aa/0x1c0[ 682.146712] ? report_bug+0x1c8/0x1e0[ 682.146717] ? handle_bug+0x3c/0x70[ 682.146721] ? exc_invalid_op+0x14/0x70[ 682.146723] ? asm_exc_invalid_op+0x16/0x20[ 682.146727] ? group_cpus_evenly+0x1aa/0x1c0[ 682.146729] ? group_cpus_evenly+0x15c/0x1c0[ 682.146731] create_affinity_masks+0xaf/0x1a0[ 682.146735] virtio_vdpa_find_vqs+0x83/0x1d0[ 682.146738] ? __pfx_default_calc_sets+0x10/0x10[ 682.146742] virtnet_find_vqs+0x1f0/0x370[ 682.146747] virtnet_probe+0x501/0xcd0[ 682.146749] ? vp_modern_get_status+0x12/0x20[ 682.146751] ? get_cap_addr.isra.0+0x10/0xc0[ 682.146754] virtio_dev_probe+0x1af/0x260[ 682.146759] really_probe+0x1a5/0x410

Description: In the Linux kernel, the following vulnerability has been resolved:sched/psi: use kernfs polling functions for PSI trigger pollingDestroying psi trigger in cgroup_file_release causes UAF issues whena cgroup is removed from under a polling process. This is happeningbecause cgroup removal causes a call to cgroup_file_release while theactual file is still alive. Destroying the trigger at this point wouldalso destroy its waitqueue head and if there is still a polling processon that file accessing the waitqueue, it will step on the freed pointer:do_select vfs_poll do_rmdir cgroup_rmdir kernfs_drain_open_files cgroup_file_release cgroup_pressure_release psi_trigger_destroy wake_up_pollfree(&t->event_wait)// vfs_poll is unblocked synchronize_rcu kfree(t) poll_freewait -> UAF access to the trigger's waitqueue headPatch [1] fixed this issue for epoll() case using wake_up_pollfree(),however the same issue exists for synchronous poll() case.The root cause of this issue is that the lifecycles of the psi trigger'swaitqueue and of the file associated with the trigger are different. Fixthis by using kernfs_generic_poll function when polling on cgroup-specificpsi triggers. It internally uses kernfs_open_node->poll waitqueue headwith its lifecycle tied to the file's lifecycle. This also renders thefix in [1] obsolete, so revert it.[1] commit c2dbe32d5db5 ("sched/psi: Fix use-after-free in ep_remove_wait_queue()")

If balance completes and returns 0,but we have a pause or cancel request we won't do the appropriatecleanup, and then the next time we try to start a balance we'll tripthis ASSERT.The error handling is just wrong here, we always want to clean up,unless we got -ECANCELLED and we set the appropriate pause flag in theexclusive op.

CVE-2023-54026 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:opp: Fix use-after-free in lazy_opp_tables after probe deferralWhen dev_pm_opp_of_find_icc_paths() in _allocate_opp_table() returns-EPROBE_DEFER, the opp_table is freed again, to wait until all theinterconnect paths are available.However, if the OPP table is using required-opps then it may alreadyhave been added to the global lazy_opp_tables list. The error pathdoes not remove the opp_table from the list again.This can cause crashes later when the provider of the required-oppsis added, since we will iterate over OPP tables that have already beenfreed. E.g.: Unable to handle kernel NULL pointer dereference when read CPU: 0 PID: 7 Comm: kworker/0:0 Not tainted 6.4.0-rc3 PC is at _of_add_opp_table_v2 (include/linux/of.h:949 drivers/opp/of.c:98 drivers/opp/of.c:344 drivers/opp/of.c:404 drivers/opp/of.c:1032) -> lazy_link_required_opp_table()Fix this by calling _of_clear_opp_table() to remove the opp_table fromthe list and clear other allocated resources. While at it, also add themissing mutex_destroy() calls in the error path.

CVE-2023-54027 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:iio: core: Prevent invalid memory access when there is no parentCommit 813665564b3d ("iio: core: Convert to use firmware node handleinstead of OF node") switched the kind of nodes to use for labelretrieval in device registration. Probably an unwanted change in thatcommit was that if the device has no parent then NULL pointer isaccessed. This is what happens in the stock IIO dummy driver when anew entry is created in configfs: # mkdir /sys/kernel/config/iio/devices/dummy/foo BUG: kernel NULL pointer dereference, address: ... ... Call Trace: __iio_device_register iio_dummy_probeSince there seems to be no reason to make a parent device of an IIOdummy device mandatory, let's prevent the invalid memory access in__iio_device_register when the parent device is NULL. With thischange, the IIO dummy driver works fine with configfs.

Description: In the Linux kernel, the following vulnerability has been resolved:vdpa: Add queue index attr to vdpa_nl_policy for nlattr length checkThe vdpa_nl_policy structure is used to validate the nlattr when parsingthe incoming nlmsg. It will ensure the attribute being described producesa valid nlattr pointer in info->attrs before entering into each handlerin vdpa_nl_ops.That is to say, the missing part in vdpa_nl_policy may lead to illegalnlattr after parsing, which could lead to OOB read just like CVE-2023-3773.This patch adds the missing nla_policy for vdpa queue index attr to avoidsuch bugs.

Further debugging showedthat igb_enable_sriov()'s call to pci_enable_sriov() is failing, becausedev->is_physfn is 0 on 82580.Prior to commit 50f303496d92 ("igb: Enable SR-IOV after reinit"),igb_enable_sriov() jumped into the "err_out" cleanup branch. After thiscommit it only returned the error code.So the cleanup didn't take place, and the incorrect VF setup in theigb_adapter structure fooled the igb driver into assuming that VFs havebeen set up where no VF actually existed.Fix this problem by cleaning up again if pci_enable_sriov() fails.

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:rcu: dump vmalloc memory info safelyCurrently, for double invoke call_rcu(), will dump rcu_head objects memoryinfo, if the objects is not allocated from the slab allocator, thevmalloc_dump_obj() will be invoke and the vmap_area_lock spinlock need tobe held, since the call_rcu() can be invoked in interrupt context,therefore, there is a possibility of spinlock deadlock scenarios.And in Preempt-RT kernel, the rcutorture test also trigger the followinglockdep warning:BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 1, name: swapper/0preempt_count: 1, expected: 0RCU nest depth: 1, expected: 13 locks held by swapper/0/1: #0: ffffffffb534ee80 (fullstop_mutex){+.+.}-{4:4}, at: torture_init_begin+0x24/0xa0 #1: ffffffffb5307940 (rcu_read_lock){....}-{1:3}, at: rcu_torture_init+0x1ec7/0x2370 #2: ffffffffb536af40 (vmap_area_lock){+.+.}-{3:3}, at: find_vmap_area+0x1f/0x70irq event stamp: 565512hardirqs last enabled at (565511): [] __call_rcu_common+0x218/0x940hardirqs last disabled at (565512): [] rcu_torture_init+0x20b2/0x2370softirqs last enabled at (399112): [] __local_bh_enable_ip+0x126/0x170softirqs last disabled at (399106): [] inet_register_protosw+0x9/0x1d0Preemption disabled at:[] rcu_torture_init+0x1f13/0x2370CPU: 0 PID: 1 Comm: swapper/0 Tainted: G W 6.5.0-rc4-rt2-yocto-preempt-rt+ #15Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.16.2-0-gea1b7a073390-prebuilt.qemu.org 04/01/2014Call Trace: dump_stack_lvl+0x68/0xb0 dump_stack+0x14/0x20 __might_resched+0x1aa/0x280 ? __pfx_rcu_torture_err_cb+0x10/0x10 rt_spin_lock+0x53/0x130 ? find_vmap_area+0x1f/0x70 find_vmap_area+0x1f/0x70 vmalloc_dump_obj+0x20/0x60 mem_dump_obj+0x22/0x90 __call_rcu_common+0x5bf/0x940 ? debug_smp_processor_id+0x1b/0x30 call_rcu_hurry+0x14/0x20 rcu_torture_init+0x1f82/0x2370 ? __pfx_rcu_torture_leak_cb+0x10/0x10 ? __pfx_rcu_torture_leak_cb+0x10/0x10 ? __pfx_rcu_torture_init+0x10/0x10 do_one_initcall+0x6c/0x300 ? debug_smp_processor_id+0x1b/0x30 kernel_init_freeable+0x2b9/0x540 ? __pfx_kernel_init+0x10/0x10 kernel_init+0x1f/0x150 ret_from_fork+0x40/0x50 ? __pfx_kernel_init+0x10/0x10 ret_from_fork_asm+0x1b/0x30 The previous patch fixes this by using the deadlock-safe best-effortversion of find_vm_area.

CVE-2023-54117 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:s390/dcssblk: fix kernel crash with list_add corruptionCommit fb08a1908cb1 ("dax: simplify the dax_device <-> gendiskassociation") introduced new logic for gendisk association, requiringdrivers to explicitly call dax_add_host() and dax_remove_host().For dcssblk driver, some dax_remove_host() calls were missing, e.g. indevice remove path. The commit also broke error handling for out_dax casein device add path, resulting in an extra put_device() w/o the previousget_device() in that case.This lead to stale xarray entries after device add / remove cycles. In thecase when a previously used struct gendisk pointer (xarray index) would beused again, because blk_alloc_disk() happened to return such a pointer, thexa_insert() in dax_add_host() would fail and go to out_dax, doing the extraput_device() in the error path. In combination with an already flawed errorhandling in dcssblk (device_register() cleanup), which needs to beaddressed in a separate patch, this resulted in a missing device_del() /klist_del(), and eventually in the kernel crash with list_add corruption ona subsequent device_add() / klist_add().Fix this by adding the missing dax_remove_host() calls, and also move theput_device() in the error path to restore the previous logic.

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

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

The function registers its global DNS resolver cache as current->cred.thread_keyring and passes the query to request_key_net() -> request_key_tag() -> request_key_and_link().* Function request_key_and_link() creates a keyring_search_context object. Its match_data.cmp method gets set via a call to type->match_preparse() (resolves to dns_resolver_match_preparse()) to dns_resolver_cmp().* Function request_key_and_link() continues and invokes search_process_keyrings_rcu() which returns that a given key was not found. The control is then passed to request_key_and_link() -> construct_alloc_key().* Concurrently to that, a second task similarly makes a DNS query for "abcdef." and its result gets inserted into the DNS resolver cache.* Back on the first task, function construct_alloc_key() first runs __key_link_begin() to determine an assoc_array_edit operation to insert a new key. Index keys in the array are compared exactly as-is, using keyring_compare_object(). The operation ---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:x86/hyperv: Disable IBT when hypercall page lacks ENDBR instructionOn hardware that supports Indirect Branch Tracking (IBT), Hyper-V VMswith ConfigVersion 9.3 or later support IBT in the guest. However,current versions of Hyper-V have a bug in that there's not an ENDBR64instruction at the beginning of the hypercall page. Since hypercalls aremade with an indirect call to the hypercall page, all hypercall attemptsfail with an exception and Linux panics.A Hyper-V fix is in progress to add ENDBR64. But guard against the Linuxpanic by clearing X86_FEATURE_IBT if the hypercall page doesn't startwith ENDBR. The VM will boot and run without IBT.If future Linux 32-bit kernels were to support IBT, additional hypercallpage hackery would be needed to make IBT work for such kernels in aHyper-V VM.

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: taprio: Limit TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME to INT_MAX.syzkaller found zero division error [0] in div_s64_rem() called fromget_cycle_time_elapsed(), where sched->cycle_time is the divisor.We have tests in parse_taprio_schedule() so that cycle_time will neverbe 0, and actually cycle_time is not 0 in get_cycle_time_elapsed().The problem is that the types of divisor are different; cycle_time iss64, but the argument of div_s64_rem() is s32.syzkaller fed this input and 0x100000000 is cast to s32 to be 0. @TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME={0xc, 0x8, 0x100000000}We use s64 for cycle_time to cast it to ktime_t, so let's keep it andset max for cycle_time.While at it, we prevent overflow in setup_txtime() and add anothertest in parse_taprio_schedule() to check if cycle_time overflows.Also, we add a new tdc test case for this issue.[0]:divide error: 0000 [#1] PREEMPT SMP KASAN NOPTICPU: 1 PID: 103 Comm: kworker/1:3 Not tainted 6.5.0-rc1-00330-g60cc1f7d0605 #3Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.0-0-gd239552ce722-prebuilt.qemu.org 04/01/2014Workqueue: ipv6_addrconf addrconf_dad_workRIP: 0010:div_s64_rem include/linux/math64.h:42 [inline]RIP: 0010:get_cycle_time_elapsed net/sched/sch_taprio.c:223 [inline]RIP: 0010:find_entry_to_transmit+0x252/0x7e0 net/sched/sch_taprio.c:344Code: 3c 02 00 0f 85 5e 05 00 00 48 8b 4c 24 08 4d 8b bd 40 01 00 00 48 8b 7c 24 48 48 89 c8 4c 29 f8 48 63 f7 48 99 48 89 74 24 70 <48> f7 fe 48 29 d1 48 8d 04 0f 49 89 cc 48 89 44 24 20 49 8d 85 10RSP: 0018:ffffc90000acf260 EFLAGS: 00010206RAX: 177450e0347560cf RBX: 0000000000000000 RCX: 177450e0347560cfRDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000100000000RBP: 0000000000000056 R08: 0000000000000000 R09: ffffed10020a0934R10: ffff8880105049a7 R11: ffff88806cf3a520 R12: ffff888010504800R13: ffff88800c00d800 R14: ffff8880105049a0 R15: 0000000000000000FS: 0000000000000000(0000) GS:ffff88806cf00000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007f0edf84f0e8 CR3: 000000000d73c002 CR4: 0000000000770ee0PKRU: 55555554Call Trace: get_packet_txtime net/sched/sch_taprio.c:508 [inline] taprio_enqueue_one+0x900/0xff0 net/sched/sch_taprio.c:577 taprio_enqueue+0x378/0xae0 net/sched/sch_taprio.c:658 dev_qdisc_enqueue+0x46/0x170 net/core/dev.c:3732 __dev_xmit_skb net/core/dev.c:3821 [inline] __dev_queue_xmit+0x1b2f/0x3000 net/core/dev.c:4169 dev_queue_xmit include/linux/netdevice.h:3088 [inline] neigh_resolve_output net/core/neighbour.c:1552 [inline] neigh_resolve_output+0x4a7/0x780 net/core/neighbour.c:1532 neigh_output include/net/neighbour.h:544 [inline] ip6_finish_output2+0x924/0x17d0 net/ipv6/ip6_output.c:135 __ip6_finish_output+0x620/0xaa0 net/ipv6/ip6_output.c:196 ip6_finish_output net/ipv6/ip6_output.c:207 [inline] NF_HOOK_COND include/linux/netfilter.h:292 [inline] ip6_output+0x206/0x410 net/ipv6/ip6_output.c:228 dst_output include/net/dst.h:458 [inline] NF_HOOK.constprop.0+0xea/0x260 include/linux/netfilter.h:303 ndisc_send_skb+0x872/0xe80 net/ipv6/ndisc.c:508 ndisc_send_ns+0xb5/0x130 net/ipv6/ndisc.c:666 addrconf_dad_work+0xc14/0x13f0 net/ipv6/addrconf.c:4175 process_one_work+0x92c/0x13a0 kernel/workqueue.c:2597 worker_thread+0x60f/0x1240 kernel/workqueue.c:2748 kthread+0x2fe/0x3f0 kernel/kthread.c:389 ret_from_fork+0x2c/0x50 arch/x86/entry/entry_64.S:308 Modules linked in:

CVE-2023-54276 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:nfsd: move init of percpu reply_cache_stats counters back to nfsd_init_netCommit f5f9d4a314da ("nfsd: move reply cache initialization into nfsdstartup") moved the initialization of the reply cache into nfsd startup,but didn't account for the stats counters, which can be accessed beforenfsd is ever started. The result can be a NULL pointer dereference whensomeone accesses /proc/fs/nfsd/reply_cache_stats while nfsd is stillshut down.This is a regression and a user-triggerable oops in the right situation:- non-x86_64 arch- /proc/fs/nfsd is mounted in the namespace- nfsd is not started in the namespace- unprivileged user calls "cat /proc/fs/nfsd/reply_cache_stats"Although this is easy to trigger on some arches (like aarch64), onx86_64, calling this_cpu_ptr(NULL) evidently returns a pointer to thefixed_percpu_data. That struct looks just enough like a newlyinitialized percpu var to allow nfsd_reply_cache_stats_show to accessit without Oopsing.Move the initialization of the per-net+per-cpu reply-cache countersback into nfsd_init_net, while leaving the rest of the reply cacheallocations to be done at nfsd startup time.Kudos to Eirik who did most of the legwork to track this down.

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

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

CVE-2025-21710 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:tcp: correct handling of extreme memory squeezeTesting with iperf3 using the "pasta" protocol splicer has revealeda problem in the way tcp handles window advertising in extreme memorysqueeze situations.Under memory pressure, a socket endpoint may temporarily advertisea zero-sized window, but this is not stored as part of the socket data.The reasoning behind this is that it is considered a temporary settingwhich shouldn't influence any further calculations.However, if we happen to stall at an unfortunate value of the currentwindow size, the algorithm selecting a new value will consistently failto advertise a non-zero window once we have freed up enough memory.This means that this side's notion of the current window size isdifferent from the one last advertised to the peer, causing the latterto not send any data to resolve the sitution.The problem occurs on the iperf3 server side, and the socket in questionis a completely regular socket with the default settings for thefedora40 kernel.

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. This is happening in practice on a debug kernel withCONFIG_DEBUG_VM_PGTABLE=y, for example this is the output with some extradebugging I added (it prints a warning trace if pgtables_bytes goesnegative, in addition to the warning at check_mm() function):[ 2.539353] debug_vm_pgtable: [get_random_vaddr ]: random_vaddr is 0x7ea247140000[ 2.539366] kmem_cache info[ 2.539374] kmem_cachep 0x000000002ce82385 - freelist 0x0000000000000000 - offset 0x508[ 2.539447] debug_vm_pgtable: [init_args ]: args->mm is 0x000000002267cc9e(...)[ 2.552800] WARNING: CPU: 5 PID: 116 at include/linux/mm.h:2841 free_pud_range+0x8bc/0x8d0[ 2.552816] Modules linked in:[ 2.552843] CPU: 5 UID: 0 PID: 116 Comm: modprobe Not tainted 6.12.0-105.debug_vm2.el10.ppc64le+debug #1 VOLUNTARY[ 2.552859] Hardware name: IBM,9009-41A POWER9 (architected) 0x4e0202 0xf000005 of:IBM,FW910.00 (VL910_062) hv:phyp pSeries[ 2.552872] NIP: c0000000007eef3c LR: c0000000007eef30 CTR: c0000000003d8c90[ 2.552885] REGS: c0000000622e73b0 TRAP: 0700 Not tainted (6.12.0-105.debug_vm2.el10.ppc64le+debug)[ 2.552899] MSR: 800000000282b033 CR: 24002822 XER: 0000000a[ 2.552954] CFAR: c0000000008f03f0 IRQMASK: 0[ 2.552954] GPR00: c0000000007eef30 c0000000622e7650 c000000002b1ac00 0000000000000001[ 2.552954] GPR04: 0000000000000008 0000000000000000 c0000000007eef30 ffffffffffffffff[ 2.552954] GPR08: 00000000ffff00f5 0000000000000001 0000000000000048 0000000000004000[ 2.552954] GPR12: 00000003fa440000 c000000017ffa300 c0000000051d9f80 ffffffffffffffdb[ 2.552954] GPR16: 0000000000000000 0000000000000008 000000000000000a 60000000000000e0[ 2.552954] GPR20: 4080000000000000 c0000000113af038 00007fffcf130000 0000700000000000[ 2.552954] GPR24: c000000062a6a000 0000000000000001 8000000062a68000 0000000000000001[ 2.552954] GPR28: 000000000000000a c000000062ebc600 0000000000002000 c000000062ebc760[ 2.553170] NIP [c0000000007eef3c] free_pud_range+0x8bc/0x8d0[ 2.553185] LR [c0000000007eef30] free_pud_range+0x8b0/0x8d0[ 2.553199] Call Trace:[ 2.553207] [c0000000622e7650] [c0000000007eef30] free_pud_range+0x8b0/0x8d0 (unreliable)[ 2.553229] [c0000000622e7750] [c0000000007f40b4] free_pgd_range+0x284/0x3b0[ 2.553248] [c0000000622e7800] [c0000000007f4630] free_pgtables+0x450/0x570[ 2.553274] [c0000000622e78e0] [c0000000008161c0] exit_mmap+0x250/0x650[ 2.553292] [c0000000622e7a30] [c0000000001b95b8] __mmput+0x98/0x290[ 2.558344] [c0000000622e7a80] [c0000000001d1018] exit_mm+0x118/0x1b0[ 2.558361] [c0000000622e7ac0] [c0000000001d141c] do_exit+0x2ec/0x870[ 2.558376] [c0000000622e7b60] [c0000000001d1ca8] do_group_exit+0x88/0x150[ 2.558391] [c0000000622e7bb0] [c0000000001d1db8] sys_exit_group+0x48/0x50[ 2.558407] [c0000000622e7be0] [c00000000003d810] system_call_exception+0x1e0/0x4c0[ 2.558423] [c0000000622e7e50] [c00000000000d05c] system_call_vectored_common+0x15c/0x2ec(...)[ 2.558892] ---[ end trace 0000000000000000 ]---[ 2.559022] BUG: Bad rss-counter state mm:000000002267cc9e type:MM_ANONPAGES val:1[ 2.559037] BUG: non-zero pgtables_bytes on freeing mm: -6144Here the modprobe process ended up with an allocated mm_struct from themm_struct slab that was used before by the debug_vm_pgtable test.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:drm/xe/guc: Check GuC running state before deregistering exec queueIn normal operation, a registered exec queue is disabled andderegistered through the GuC, and freed only after the GuC confirmscompletion. However, if the driver is forced to unbind while the execqueue is still running, the user may call exec_destroy() after the GuChas already been stopped and CT communication disabled.In this case, the driver cannot receive a response from the GuC,preventing proper cleanup of exec queue resources. Fix this by directlyreleasing the resources when GuC is not running.Here is the failure dmesg log:"[ 468.089581] ---[ end trace 0000000000000000 ]---[ 468.089608] pci 0000:03:00.0: [drm] *ERROR* GT0: GUC ID manager unclean (1/65535)[ 468.090558] pci 0000:03:00.0: [drm] GT0: total 65535[ 468.090562] pci 0000:03:00.0: [drm] GT0: used 1[ 468.090564] pci 0000:03:00.0: [drm] GT0: range 1..1 (1)[ 468.092716] ------------[ cut here ]------------[ 468.092719] WARNING: CPU: 14 PID: 4775 at drivers/gpu/drm/xe/xe_ttm_vram_mgr.c:298 ttm_vram_mgr_fini+0xf8/0x130 [xe]"v2: use xe_uc_fw_is_running() instead of xe_guc_ct_enabled().

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:vsock: fix lock inversion in vsock_assign_transport()Syzbot reported a potential lock inversion deadlock betweenvsock_register_mutex and sk_lock-AF_VSOCK when vsock_linger() is called.The issue was introduced by commit 687aa0c5581b ("vsock: Fixtransport_* TOCTOU") which added vsock_register_mutex locking invsock_assign_transport() around the transport->release() call, that cancall vsock_linger(). vsock_assign_transport() can be called with sk_lockheld. vsock_linger() calls sk_wait_event() that temporarily releases andre-acquires sk_lock. During this window, if another thread holdvsock_register_mutex while trying to acquire sk_lock, a circulardependency is created.Fix this by releasing vsock_register_mutex before callingtransport->release() and vsock_deassign_transport(). This is safebecause we don't need to hold vsock_register_mutex while releasing theold transport, and we ensure the new transport won't disappear byobtaining a module reference first via try_module_get().

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

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

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

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

CVE-2025-40250 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5: Clean up only new IRQ glue on request_irq() failureThe mlx5_irq_alloc() function can inadvertently free the entire rmapand end up in a crash[1] when the other threads tries to access this,when request_irq() fails due to exhausted IRQ vectors. This commitmodifies the cleanup to remove only the specific IRQ mapping that wasjust added.This prevents removal of other valid mappings and ensures precisecleanup of the failed IRQ allocation's associated glue object.Note: This error is observed when both fwctl and rds configs are enabled.[1]mlx5_core 0000:05:00.0: Successfully registered panic handler for port 1mlx5_core 0000:05:00.0: mlx5_irq_alloc:293:(pid 66740): Failed torequest irq. err = -28infiniband mlx5_0: mlx5_ib_test_wc:290:(pid 66740): Error -28 whiletrying to test write-combining supportmlx5_core 0000:05:00.0: Successfully unregistered panic handler for port 1mlx5_core 0000:06:00.0: Successfully registered panic handler for port 1mlx5_core 0000:06:00.0: mlx5_irq_alloc:293:(pid 66740): Failed torequest irq. err = -28infiniband mlx5_0: mlx5_ib_test_wc:290:(pid 66740): Error -28 whiletrying to test write-combining supportmlx5_core 0000:06:00.0: Successfully unregistered panic handler for port 1mlx5_core 0000:03:00.0: mlx5_irq_alloc:293:(pid 28895): Failed torequest irq. err = -28mlx5_core 0000:05:00.0: mlx5_irq_alloc:293:(pid 28895): Failed torequest irq. err = -28general protection fault, probably for non-canonical address0xe277a58fde16f291: 0000 [#1] SMP NOPTIRIP: 0010:free_irq_cpu_rmap+0x23/0x7dCall Trace: ? show_trace_log_lvl+0x1d6/0x2f9 ? show_trace_log_lvl+0x1d6/0x2f9 ? mlx5_irq_alloc.cold+0x5d/0xf3 [mlx5_core] ? __die_body.cold+0x8/0xa ? die_addr+0x39/0x53 ? exc_general_protection+0x1c4/0x3e9 ? dev_vprintk_emit+0x5f/0x90 ? asm_exc_general_protection+0x22/0x27 ? free_irq_cpu_rmap+0x23/0x7d mlx5_irq_alloc.cold+0x5d/0xf3 [mlx5_core] irq_pool_request_vector+0x7d/0x90 [mlx5_core] mlx5_irq_request+0x2e/0xe0 [mlx5_core] mlx5_irq_request_vector+0xad/0xf7 [mlx5_core] comp_irq_request_pci+0x64/0xf0 [mlx5_core] create_comp_eq+0x71/0x385 [mlx5_core] ? mlx5e_open_xdpsq+0x11c/0x230 [mlx5_core] mlx5_comp_eqn_get+0x72/0x90 [mlx5_core] ? xas_load+0x8/0x91 mlx5_comp_irqn_get+0x40/0x90 [mlx5_core] mlx5e_open_channel+0x7d/0x3c7 [mlx5_core] mlx5e_open_channels+0xad/0x250 [mlx5_core] mlx5e_open_locked+0x3e/0x110 [mlx5_core] mlx5e_open+0x23/0x70 [mlx5_core] __dev_open+0xf1/0x1a5 __dev_change_flags+0x1e1/0x249 dev_change_flags+0x21/0x5c do_setlink+0x28b/0xcc4 ? __nla_parse+0x22/0x3d ? inet6_validate_link_af+0x6b/0x108 ? cpumask_next+0x1f/0x35 ? __snmp6_fill_stats64.constprop.0+0x66/0x107 ? __nla_validate_parse+0x48/0x1e6 __rtnl_newlink+0x5ff/0xa57 ? kmem_cache_alloc_trace+0x164/0x2ce rtnl_newlink+0x44/0x6e rtnetlink_rcv_msg+0x2bb/0x362 ? __netlink_sendskb+0x4c/0x6c ? netlink_unicast+0x28f/0x2ce ? rtnl_calcit.isra.0+0x150/0x146 netlink_rcv_skb+0x5f/0x112 netlink_unicast+0x213/0x2ce netlink_sendmsg+0x24f/0x4d9 __sock_sendmsg+0x65/0x6a ____sys_sendmsg+0x28f/0x2c9 ? import_iovec+0x17/0x2b ___sys_sendmsg+0x97/0xe0 __sys_sendmsg+0x81/0xd8 do_syscall_64+0x35/0x87 entry_SYSCALL_64_after_hwframe+0x6e/0x0RIP: 0033:0x7fc328603727Code: c3 66 90 41 54 41 89 d4 55 48 89 f5 53 89 fb 48 83 ec 10 e8 0b edff ff 44 89 e2 48 89 ee 89 df 41 89 c0 b8 2e 00 00 00 0f 05 <48> 3d 00f0 ff ff 77 35 44 89 c7 48 89 44 24 08 e8 44 ed ff ff 48RSP: 002b:00007ffe8eb3f1a0 EFLAGS: 00000293 ORIG_RAX: 000000000000002eRAX: ffffffffffffffda RBX: 000000000000000d RCX: 00007fc328603727RDX: 0000000000000000 RSI: 00007ffe8eb3f1f0 RDI: 000000000000000dRBP: 00007ffe8eb3f1f0 R08: 0000000000000000 R09: 0000000000000000R10: 0000000000000000 R11: 0000000000000293 R12: 0000000000000000R13: 00000000000---truncated---

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

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

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

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

CVE-2025-40256 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:xfrm: also call xfrm_state_delete_tunnel at destroy time for states that were never addedIn commit b441cf3f8c4b ("xfrm: delete x->tunnel as we delete x"), Imissed the case where state creation fails between fullinitialization (->init_state has been called) and being inserted onthe lists.In this situation, ->init_state has been called, so for IPcomptunnels, the fallback tunnel has been created and added onto thelists, but the user state never gets added, because we fail beforethat. The user state doesn't go through __xfrm_state_delete, so wedon't call xfrm_state_delete_tunnel for those states, and we end upleaking the FB tunnel.There are several codepaths affected by this: the add/update paths, inboth net/key and xfrm, and the migrate code (xfrm_migrate,xfrm_state_migrate). A "proper" rollback of the init_state work wouldprobably be doable in the add/update code, but for migrate it getsmore complicated as multiple states may be involved.At some point, the new (not-inserted) state will be destroyed, so callxfrm_state_delete_tunnel during xfrm_state_gc_destroy. Most stateswill have their fallback tunnel cleaned up during __xfrm_state_delete,which solves the issue that b441cf3f8c4b (and other patches before it)aimed at. All states (including FB tunnels) will be removed from thelists once xfrm_state_fini has called flush_work(&xfrm_state_gc_work).

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:net: sched: act_ife: initialize struct tc_ife to fix KMSAN kernel-infoleakFix a KMSAN kernel-infoleak detected by the syzbot .[net?] KMSAN: kernel-infoleak in __skb_datagram_iterIn tcf_ife_dump(), the variable 'opt' was partially initialized using adesignatied initializer. While the padding bytes are reamineduninitialized. nla_put() copies the entire structure into anetlink message, these uninitialized bytes leaked to userspace.Initialize the structure with memset before assigning its fieldsto ensure all members and padding are cleared prior to beign copied.This change silences the KMSAN report and prevents potential informationleaks from the kernel memory.This fix has been tested and validated by syzbot. This patch closes thebug reported at the following syzkaller link and ensures no infoleak.

Description: In the Linux kernel, the following vulnerability has been resolved:exfat: fix improper check of dentry.stream.valid_sizeWe found an infinite loop bug in the exFAT file system that can lead to aDenial-of-Service (DoS) condition. When a dentry in an exFAT filesystem ismalformed, the following system calls - SYS_openat, SYS_ftruncate, andSYS_pwrite64 - can cause the kernel to hang.Root cause analysis shows that the size validation code in exfat_find()does not check whether dentry.stream.valid_size is negative. As a result,the system calls mentioned above can succeed and eventually trigger the DoSissue.This patch adds a check for negative dentry.stream.valid_size to preventthis vulnerability.

CVE-2025-40288 Severity: Moderate CVSS3 score: 5.5

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

CVE-2025-40306 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:orangefs: fix xattr related buffer overflow...Willy Tarreau forwarded me a message fromDisclosure with the followingwarning:> The helper `xattr_key()` uses the pointer variable in the loop condition> rather than dereferencing it. As `key` is incremented, it remains non-NULL> (until it runs into unmapped memory), so the loop does not terminate on> valid C strings and will walk memory indefinitely, consuming CPU or hanging> the thread.I easily reproduced this with setfattr and getfattr, causing a kerneloops, hung user processes and corrupted orangefs files. Disclosuresent along a diff (not a patch) with a suggested fix, which I basedthis patch on.After xattr_key started working right, xfstest generic/069 exposed anxattr related memory leak that lead to OOM. xattr_key returnsa hashed key. When adding xattrs to the orangefs xattr cache, orangefsused hash_add, a kernel hashing macro. hash_add also hashes the key usinghash_log which resulted in additions to the xattr cache going to the wronghash bucket. generic/069 tortures a single file and orangefs does agetattr for the xattr "security.capability" every time. Orangefsnegative caches on xattrs which includes a kmalloc. Since adds to thexattr cache were going to the wrong bucket, every getattr for"security.capability" resulted in another kmalloc, none of which wereever freed.I changed the two uses of hash_add to hlist_add_head insteadand the memory leak ceased and generic/069 quit throwing furniture.

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

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

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

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

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

This issue is caused by therecursive acquisition of the read lock enetc_mdio_lock.

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

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

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

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

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

CVE-2025-68194 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:media: imon: make send_packet() more robustsyzbot is reporting that imon has three problems which result inhung tasks due to forever holding device lock [1].First problem is that when usb_rx_callback_intf0() once got -EPROTO errorafter ictx->dev_present_intf0 became true, usb_rx_callback_intf0()resubmits urb after printk(), and resubmitted urb causesusb_rx_callback_intf0() to again get -EPROTO error. This results inprintk() flooding (RCU stalls).Alan Stern commented [2] that In theory it's okay to resubmit _if_ the driver has a robust error-recovery scheme (such as giving up after some fixed limit on the number of errors or after some fixed time has elapsed, perhaps with a time delay to prevent a flood of errors). Most drivers don't bother to do this; they simply give up right away. This makes them more vulnerable to short-term noise interference during USB transfers, but in reality such interference is quite rare. There's nothing really wrong with giving up right away.but imon has a poor error-recovery scheme which just retries forever;this behavior should be fixed.Since I'm not sure whether it is safe for imon users to give up upon anyerror code, this patch takes care of only union of error codes chosen frommodules in drivers/media/rc/ directory which handle -EPROTO error (i.e.ir_toy, mceusb and igorplugusb).Second problem is that when usb_rx_callback_intf0() once got -EPROTO errorbefore ictx->dev_present_intf0 becomes true, usb_rx_callback_intf0() alwaysresubmits urb due to commit 8791d63af0cf ("[media] imon: don't wedgehardware after early callbacks"). Move the ictx->dev_present_intf0 testintroduced by commit 6f6b90c9231a ("[media] imon: don't parse scancodesuntil intf configured") to immediately before imon_incoming_packet(), orthe first problem explained above happens without printk() flooding (i.e.hung task).Third problem is that when usb_rx_callback_intf0() is not called for somereason (e.g. flaky hardware; the reproducer for this problem sometimesprevents usb_rx_callback_intf0() from being called),wait_for_completion_interruptible() in send_packet() never returns (i.e.hung task). As a workaround for such situation, change send_packet() towait for completion with timeout of 10 seconds.

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

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

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

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

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

In both cases, calls to PF PTP cleanup (ice_ptp_cleanup_pffunction) and 'ps_lock' mutex deinitialization were missed.Additionally, ptp clock was not unregistered in the latter case.Keep PTP state as 'uninitialized' on init to distinguish between errorscenarios and to avoid resource release duplication at driver removal.The consequence of missing ice_ptp_cleanup_pf call is the following calltrace dumped when ice_adapter object is freed (port list is not empty,as it is required at this stage):[ T93022] ------------[ cut here ]------------[ T93022] WARNING: CPU: 10 PID: 93022 atice/ice_adapter.c:67 ice_adapter_put+0xef/0x100 [ice]...[ T93022] RIP: 0010:ice_adapter_put+0xef/0x100 [ice]...[ T93022] Call Trace:[ T93022] [ T93022] ? ice_adapter_put+0xef/0x100 [ice33d2647ad4f6d866d41eefff1806df37c68aef0c][ T93022] ? __warn.cold+0xb0/0x10e[ T93022] ? ice_adapter_put+0xef/0x100 [ice33d2647ad4f6d866d41eefff1806df37c68aef0c][ T93022] ? report_bug+0xd8/0x150[ T93022] ? handle_bug+0xe9/0x110[ T93022] ? exc_invalid_op+0x17/0x70[ T93022] ? asm_exc_invalid_op+0x1a/0x20[ T93022] ? ice_adapter_put+0xef/0x100 [ice33d2647ad4f6d866d41eefff1806df37c68aef0c][ T93022] pci_device_remove+0x42/0xb0[ T93022] device_release_driver_internal+0x19f/0x200[ T93022] driver_detach+0x48/0x90[ T93022] bus_remove_driver+0x70/0xf0[ T93022] pci_unregister_driver+0x42/0xb0[ T93022] ice_module_exit+0x10/0xdb0 [ice33d2647ad4f6d866d41eefff1806df37c68aef0c]...[ T93022] ---[ end trace 0000000000000000 ]---[ T93022] ice: module unloaded

Description: In the Linux kernel, the following vulnerability has been resolved:Input: pegasus-notetaker - fix potential out-of-bounds accessIn the pegasus_notetaker driver, the pegasus_probe() function allocatesthe URB transfer buffer using the wMaxPacketSize value fromthe endpoint descriptor. An attacker can use a malicious USB descriptorto force the allocation of a very small buffer.Subsequently, if the device sends an interrupt packet with a specificpattern (e.g., where the first byte is 0x80 or 0x42),the pegasus_parse_packet() function parses the packet without checkingthe allocated buffer size. This leads to an out-of-bounds memory access.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amdgpu: fix gpu page fault after hibernation on PF passthroughOn PF passthrough environment, after hibernate and then resume, coralgemmwill cause gpu page fault.Mode1 reset happens during hibernate, but partition mode is not restoredon resume, register mmCP_HYP_XCP_CTL and mmCP_PSP_XCP_CTL is not rightafter resume. When CP access the MQD BO, wrong stride size is used,this will cause out of bound access on the MQD BO, resulting page fault.The fix is to ensure gfx_v9_4_3_switch_compute_partition() is calledwhen resume from a hibernation.KFD resume is called separately during a reset recovery or resume fromsuspend sequence. Hence it's not required to be called as part ofpartition switch.(cherry picked from commit 5d1b32cfe4a676fe552416cb5ae847b215463a1a)

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:most: usb: hdm_probe: Fix calling put_device() before device initializationThe early error path in hdm_probe() can jump to err_free_mdev before&mdev->dev has been initialized with device_initialize(). Callingput_device(&mdev->dev) there triggers a device core WARN and ends upinvoking kref_put(&kobj->kref, kobject_release) on an uninitializedkobject.In this path the private struct was only kmalloc'ed and the intendedrelease is effectively kfree(mdev) anyway, so free it directly insteadof calling put_device() on an uninitialized device.This removes the WARNING and fixes the pre-initialization error path.

CVE-2025-68257 Severity: Moderate CVSS3 score: 5.5

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

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

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

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

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

The call stack includes:- `dwc3_ep0_reset_state()`- `dwc3_ep0_stall_and_restart()`- `dwc3_ep0_out_start()`- `dwc3_remove_requests()`- `dwc3_gadget_del_and_unmap_request()`Path 2:Also initiated from `dwc3_gadget_reset_interrupt()`, but through`dwc3_stop_active_transfers()`. The call stack includes:- `dwc3_stop_active_transfers()`- `dwc3_remove_requests()`- `dwc3_gadget_del_and_unmap_request()`Path 3:Occurs independently during `adb root` execution, which triggersUSB function unbind and bind operations. The sequence includes:- `gserial_disconnect()`- `usb_ep_disable()`- `dwc3_gadget_ep_disable()`- `dwc3_remove_requests()` with `-ESHUTDOWN` statusPath 3 operates asynchronously and lacks synchronization with Paths1 and 2. When Path 3 completes, it disables endpoints and frees 'out'requests. If Paths 1 or 2 are still processing these requests,accessing freed memory leads to a crash due to use-after-free conditions.To fix this added check for request completion and skip processingif already completed and added the request status for ep0 while queue.

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

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

CVE-2025-68298 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: btusb: mediatek: Avoid btusb_mtk_claim_iso_intf() NULL derefIn btusb_mtk_setup(), we set `btmtk_data->isopkt_intf` to: usb_ifnum_to_if(data->udev, MTK_ISO_IFNUM)That function can return NULL in some cases. Even when it returnsNULL, though, we still go on to call btusb_mtk_claim_iso_intf().As of commit e9087e828827 ("Bluetooth: btusb: mediatek: Add locks forusb_driver_claim_interface()"), calling btusb_mtk_claim_iso_intf()when `btmtk_data->isopkt_intf` is NULL will cause a crash becausewe'll end up passing a bad pointer to device_lock(). Prior to thatcommit we'd pass the NULL pointer directly tousb_driver_claim_interface() which would detect it and return anerror, which was handled.Resolve the crash in btusb_mtk_claim_iso_intf() by adding a NULL checkat the start of the function. This makes the code handle a NULL`btmtk_data->isopkt_intf` the same way it did before the problematiccommit (just with a slight change to the error message printed).

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

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

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

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

CVE-2025-68312 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:usbnet: Prevents free active keventThe root cause of this issue are:1. When probing the usbnet device, executing usbnet_link_change(dev, 0, 0);put the kevent work in global workqueue. However, the kevent has not yetbeen scheduled when the usbnet device is unregistered. Therefore, executingfree_netdev() results in the "free active object (kevent)" error reportedhere.2. Another factor is that when calling usbnet_disconnect()->unregister_netdev(),if the usbnet device is up, ndo_stop() is executed to cancel the kevent.However, because the device is not up, ndo_stop() is not executed.The solution to this problem is to cancel the kevent before executingfree_netdev().

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

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

CVE-2025-68332 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: c6xdigio: Fix invalid PNP driver unregistrationThe Comedi low-level driver "c6xdigio" seems to be for a parallel portconnected device. When the Comedi core calls the driver's Comedi"attach" handler `c6xdigio_attach()` to configure a Comedi to use thisdriver, it tries to enable the parallel port PNP resources byregistering a PNP driver with `pnp_register_driver()`, but ignores thereturn value. (The `struct pnp_driver` it uses has only the `name` and`id_table` members filled in.) The driver's Comedi "detach" handler`c6xdigio_detach()` unconditionally unregisters the PNP driver with`pnp_unregister_driver()`.It is possible for `c6xdigio_attach()` to return an error before itcalls `pnp_register_driver()` and it is possible for the call to`pnp_register_driver()` to return an error (that is ignored). In bothcases, the driver should not be calling `pnp_unregister_driver()` as itdoes in `c6xdigio_detach()`. (Note that `c6xdigio_detach()` will becalled by the Comedi core if `c6xdigio_attach()` returns an error, or ifthe Comedi core decides to detach the Comedi device from the driver forsome other reason.)The unconditional call to `pnp_unregister_driver()` without a previoussuccessful call to `pnp_register_driver()` will cause`driver_unregister()` to issue a warning "Unexpected driverunregister!". This was detected by Syzbot [1].Also, the PNP driver registration and unregistration should be done atmodule init and exit time, respectively, not when attaching or detachingComedi devices to the driver. (There might be more than one Comedidevice being attached to the driver, although that is unlikely.)Change the driver to do the PNP driver registration at module init time,and the unregistration at module exit time. Since `c6xdigio_detach()`now only calls `comedi_legacy_detach()`, remove the function and changethe Comedi driver "detach" handler to `comedi_legacy_detach`.-------------------------------------------[1] Syzbot sample crash report:Unexpected driver unregister!WARNING: CPU: 0 PID: 5970 at drivers/base/driver.c:273 driver_unregister drivers/base/driver.c:273 [inline]WARNING: CPU: 0 PID: 5970 at drivers/base/driver.c:273 driver_unregister+0x90/0xb0 drivers/base/driver.c:270Modules linked in:CPU: 0 UID: 0 PID: 5970 Comm: syz.0.17 Not tainted syzkaller #0 PREEMPT(full)Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 10/02/2025RIP: 0010:driver_unregister drivers/base/driver.c:273 [inline]RIP: 0010:driver_unregister+0x90/0xb0 drivers/base/driver.c:270Code: 48 89 ef e8 c2 e6 82 fc 48 89 df e8 3a 93 ff ff 5b 5d e9 c3 6d d9 fb e8 be 6d d9 fb 90 48 c7 c7 e0 f8 1f 8c e8 51 a2 97 fb 90 <0f> 0b 90 90 5b 5d e9 a5 6d d9 fb e8 e0 f4 41 fc eb 94 e8 d9 f4 41RSP: 0018:ffffc9000373f9a0 EFLAGS: 00010282RAX: 0000000000000000 RBX: ffffffff8ff24720 RCX: ffffffff817b6ee8RDX: ffff88807c932480 RSI: ffffffff817b6ef5 RDI: 0000000000000001RBP: 0000000000000000 R08: 0000000000000001 R09: 0000000000000000R10: 0000000000000001 R11: 0000000000000001 R12: ffffffff8ff24660R13: dffffc0000000000 R14: 0000000000000000 R15: ffff88814cca0000FS: 000055556dab1500(0000) GS:ffff8881249d9000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 000055f77f285cd0 CR3: 000000007d871000 CR4: 00000000003526f0Call Trace: comedi_device_detach_locked+0x12f/0xa50 drivers/comedi/drivers.c:207 comedi_device_detach+0x67/0xb0 drivers/comedi/drivers.c:215 comedi_device_attach+0x43d/0x900 drivers/comedi/drivers.c:1011 do_devconfig_ioctl+0x1b1/0x710 drivers/comedi/comedi_fops.c:872 comedi_unlocked_ioctl+0x165d/0x2f00 drivers/comedi/comedi_fops.c:2178 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:597 [inline] __se_sys_ioctl fs/ioctl.c:583 [inline] __x64_sys_ioctl+0x18e/0x210 fs/ioctl.c:583 do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline] do_sys---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: pcl818: fix null-ptr-deref in pcl818_ai_cancel()Syzbot identified an issue [1] in pcl818_ai_cancel(), which stems fromthe fact that in case of early device detach via pcl818_detach(),subdevice dev->read_subdev may not have initialized its pointer to&struct comedi_async as intended. Thus, any such dereferencing of&s->async->cmd will lead to general protection fault and kernel crash.Mitigate this problem by removing a call to pcl818_ai_cancel() frompcl818_detach() altogether. This way, if the subdevice setups itssupport for async commands, everything async-related will behandled via subdevice's own ->cancel() function incomedi_device_detach_locked() even before pcl818_detach(). If nosupport for asynchronous commands is provided, there is no needto cancel anything either.[1] Syzbot crash:Oops: general protection fault, probably for non-canonical address 0xdffffc0000000005: 0000 [#1] SMP KASAN PTIKASAN: null-ptr-deref in range [0x0000000000000028-0x000000000000002f]CPU: 1 UID: 0 PID: 6050 Comm: syz.0.18 Not tainted syzkaller #0 PREEMPT(full)Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 08/18/2025RIP: 0010:pcl818_ai_cancel+0x69/0x3f0 drivers/comedi/drivers/pcl818.c:762...Call Trace: pcl818_detach+0x66/0xd0 drivers/comedi/drivers/pcl818.c:1115 comedi_device_detach_locked+0x178/0x750 drivers/comedi/drivers.c:207 do_devconfig_ioctl drivers/comedi/comedi_fops.c:848 [inline] comedi_unlocked_ioctl+0xcde/0x1020 drivers/comedi/comedi_fops.c:2178 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:597 [inline]...

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---

With the aforementioned swappingdone, change is needed as well to apply it to the peer's receive MCS.Tested-on: WCN6855 hw2.1 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.41Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1

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

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

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

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:Input: alps - fix use-after-free bugs caused by dev3_register_workThe dev3_register_work delayed work item is initialized withinalps_reconnect() and scheduled upon receipt of the first barePS/2 packet from an external PS/2 device connected to the ALPStouchpad. During device detachment, the original implementationcalls flush_workqueue() in psmouse_disconnect() to ensurecompletion of dev3_register_work. However, the flush_workqueue()in psmouse_disconnect() only blocks and waits for work items thatwere already queued to the workqueue prior to its invocation. Anywork items submitted after flush_workqueue() is called are notincluded in the set of tasks that the flush operation awaits.This means that after flush_workqueue() has finished executing,the dev3_register_work could still be scheduled. Although thepsmouse state is set to PSMOUSE_CMD_MODE in psmouse_disconnect(),the scheduling of dev3_register_work remains unaffected.The race condition can occur as follows:CPU 0 (cleanup path) | CPU 1 (delayed work)psmouse_disconnect() | psmouse_set_state() | flush_workqueue() | alps_report_bare_ps2_packet() alps_disconnect() | psmouse_queue_work() kfree(priv); // FREE | alps_register_bare_ps2_mouse() | priv = container_of(work...); // USE | priv->dev3 // USEAdd disable_delayed_work_sync() in alps_disconnect() to ensurethat dev3_register_work is properly canceled and prevented fromexecuting after the alps_data structure has been deallocated.This bug is identified by static analysis.

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

Set a dummy blocksize before attempting toread the boot_block.The issue can be triggered with the following syz reproducer: mkdirat(0xffffffffffffff9c, &(0x7f0000000080)='./file1\x00', 0x0) r4 = openat$nullb(0xffffffffffffff9c, &(0x7f0000000040), 0x121403, 0x0) ioctl$FS_IOC_SETFLAGS(r4, 0x40081271, &(0x7f0000000980)=0x4000) mount(&(0x7f0000000140)=@nullb, &(0x7f0000000040)='./cgroup\x00', &(0x7f0000000000)='ntfs3\x00', 0x2208004, 0x0) syz_clone(0x88200200, 0x0, 0x0, 0x0, 0x0, 0x0)Here, the ioctl sets the bdev block size to 16384. During mount,get_tree_bdev_flags() calls sb_set_blocksize(sb, block_size(bdev)),but since block_size(bdev) > PAGE_SIZE, sb_set_blocksize() leavessb->s_blocksize at zero.Later, ntfs_init_from_boot() attempts to read the boot_block whilesb->s_blocksize is still zero, which triggers the bug.[almaz.alexandrovich@paragon-software.com: changed comment style, addedreturn value handling]

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

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

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

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

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-2025-71135 Severity: Moderate CVSS3 score: 5.5

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

As noted in that change, the __counted_bymember must be initialized with the number of elements before the firstarray access happens, otherwise there will be a warning from each accessprior to the initialization because the number of elements is zero. Thisoccurs in exynos_clkout_probe() due to .num being assigned after .hws[]has been accessed: UBSAN: array-index-out-of-bounds in drivers/clk/samsung/clk-exynos-clkout.c:178:18 index 0 is out of range for type 'clk_hw *[*]'Move the .num initialization to before the first access of .hws[],clearing up the warning.

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

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

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

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

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.

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

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

CVE-2026-22980 Severity: Moderate CVSS3 score: 5.5

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

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

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

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

If an ethtool command that accesses the rss lut isattempted immediately after reset, it will result in NULL ptrdereference. Also, there is no need to reset the rss lut if the soft resetdoes not involve queue count change.After soft reset, set the RSS LUT to default values based on the updatedqueue count only if the reset was a result of a queue count change andthe LUT was not configured by the user.

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-2026-23553 Severity: Moderate CVSS3 score: 5.5

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

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

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

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

CVE-2025-40303 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-2025-69418 Severity: Moderate CVSS3 score: 5.3

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

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

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

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

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

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

CVE-2025-69420 Severity: Moderate CVSS3 score: 5.3

Description: Issue summary: A type confusion vulnerability exists in the TimeStamp Responseverification code where an ASN1_TYPE union member is accessed without firstvalidating the type, causing an invalid or NULL pointer dereference whenprocessing a malformed TimeStamp Response file.Impact summary: An application calling TS_RESP_verify_response() with amalformed TimeStamp Response can be caused to dereference an invalid orNULL pointer when reading, resulting in a Denial of Service.The functions ossl_ess_get_signing_cert() and ossl_ess_get_signing_cert_v2()access the signing cert attribute value without validating its type.When the type is not V_ASN1_SEQUENCE, this results in accessing invalid memorythrough the ASN1_TYPE union, causing a crash.Exploiting this vulnerability requires an attacker to provide a malformedTimeStamp Response to an application that verifies timestamp responses. TheTimeStamp protocol (RFC 3161) is not widely used and the impact of theexploit is just a Denial of Service. For these reasons the issue wasassessed as Low severity.The FIPS modules in 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,as the TimeStamp Response implementation is outside the OpenSSL FIPS moduleboundary.OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0 and 1.1.1 are vulnerable to this issue.OpenSSL 1.0.2 is not affected by this issue.

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:erofs: kill hooked chains to avoid loops on deduplicated compressed imagesAfter heavily stressing EROFS with several images which include ahand-crafted image of repeated patterns for more than 46 days, I foundtwo chains could be linked with each other almost simultaneously andform a loop so that the entire loop won't be submitted. As aconsequence, the corresponding file pages will remain locked forever.It can be _only_ observed on data-deduplicated compressed images.For example, consider two chains with five pclusters in total: Chain 1: 2->3->4->5 -- The tail pcluster is 5; Chain 2: 5->1->2 -- The tail pcluster is 2.Chain 2 could link to Chain 1 with pcluster 5; and Chain 1 could linkto Chain 2 at the same time with pcluster 2.Since hooked chains are all linked locklessly now, I have no idea howto simply avoid the race. Instead, let's avoid hooked chains completelyuntil I could work out a proper way to fix this and end users finallytell us that it's needed to add it back.Actually, this optimization can be found with multi-threaded workloads(especially even more often on deduplicated compressed images), yet I'mnot sure about the overall system impacts of not having this comparedwith implementation complexity.

CVE-2023-54072 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: pcm: Fix potential data race at PCM memory allocation helpersThe PCM memory allocation helpers have a sanity check against too manybuffer allocations. However, the check is performed without a properlock and the allocation isn't serialized; this allows user to allocatemore memories than predefined max size.Practically seen, this isn't really a big problem, as it's more orless some "soft limit" as a sanity check, and it's not possible toallocate unlimitedly. But it's still better to address this for moreconsistent behavior.The patch covers the size check in do_alloc_pages() with thecard->memory_mutex, and increases the allocated size there forpreventing the further overflow. When the actual allocation fails,the size is decreased accordingly.

After that wait_event_killable() is interrupted (it returns-ERESTARTSYS), so that 'wq->name.name == NULL' condition may be notsatisfied. Actually, this condition can be satisfied whenautofs_wait_release() or autofs_catatonic_mode() is called and, what isalso important, wait_ctr is decremented in those places. Upon the exit ofautofs_wait(), wait_ctr is decremented to 1. Then the unmounting processbegins: kill_sb calls autofs_catatonic_mode(), which should have freed thewaitqueues, but it only decrements its usage counter to zero which is nota correct behaviour.edit:imkThis description is of course not correct. The umount performed as a resultof an expire is a umount of a mount that has been automounted, it's not theautofs mount itself. They happen independently, usually after everythingmounted within the autofs file system has been expired away. If everythinghasn't been expired away the automount daemon can still exit leaving mountsin place. But expires done in both cases will result in a notification thatcalls autofs_wait_release() with a result status. The problem case is thesummary execution of of the automount daemon. In this case any waitingprocesses won't be woken up until either they are terminated or the mountis umounted.end edit: imkSo in catatonic mode we should free waitqueues which counter becomes zero.edit: imkInitially I was concerned that the calling of autofs_wait_release() andautofs_catatonic_mode() was not mutually exclusive but that can't be thecase (obviously) because the queue entry (or entries) is removed from thelist when either of these two functions are called. Consequently the waitentry will be freed by only one of these functions or by the woken processin autofs_wait() depending on the order of the calls.end edit: imk

Description: In the Linux kernel, the following vulnerability has been resolved:igc: Fix Kernel Panic during ndo_tx_timeout callbackThe Xeon validation group has been carrying out some loaded testswith various HW configurations, and they have seen some transmitqueue time out happening during the test. This will cause thereset adapter function to be called by igc_tx_timeout().Similar race conditions may arise when the interface is being broughtdown and up in igc_reinit_locked(), an interrupt being generated, andigc_clean_tx_irq() being called to complete the TX.When the igc_tx_timeout() function is invoked, this patch will turnoff all TX ring HW queues during igc_down() process. TX ring HW queueswill be activated again during the igc_configure_tx_ring() processwhen performing the igc_up() procedure later.This patch also moved existing igc_disable_tx_ring_hw() to avoid usingforward declaration.Kernel trace:[ 7678.747813] ------------[ cut here ]------------[ 7678.757914] NETDEV WATCHDOG: enp1s0 (igc): transmit queue 2 timed out[ 7678.770117] WARNING: CPU: 0 PID: 13 at net/sched/sch_generic.c:525 dev_watchdog+0x1ae/0x1f0[ 7678.784459] Modules linked in: xt_conntrack nft_chain_nat xt_MASQUERADE xt_addrtype nft_compatnf_tables nfnetlink br_netfilter bridge stp llc overlay dm_mod emrcha(PO) emriio(PO) rktpm(PO)cegbuf_mod(PO) patch_update(PO) se(PO) sgx_tgts(PO) mktme(PO) keylocker(PO) svtdx(PO) svfs_pci_hotplug(PO)vtd_mod(PO) davemem(PO) svmabort(PO) svindexio(PO) usbx2(PO) ehci_sched(PO) svheartbeat(PO) ioapic(PO)sv8259(PO) svintr(PO) lt(PO) pcierootport(PO) enginefw_mod(PO) ata(PO) smbus(PO) spiflash_cdf(PO) arden(PO)dsa_iax(PO) oobmsm_punit(PO) cpm(PO) svkdb(PO) ebg_pch(PO) pch(PO) sviotargets(PO) svbdf(PO) svmem(PO)svbios(PO) dram(PO) svtsc(PO) targets(PO) superio(PO) svkernel(PO) cswitch(PO) mcf(PO) pentiumIII_mod(PO)fs_svfs(PO) mdevdefdb(PO) svfs_os_services(O) ixgbe mdio mdio_devres libphy emeraldrapids_svdefs(PO)regsupport(O) libnvdimm nls_cp437 snd_hda_codec_realtek snd_hda_codec_generic ledtrig_audio snd_hda_intelsnd_intel_dspcfg snd_hda_codec snd_hwdep x86_pkg_temp_thermal snd_hda_core snd_pcm snd_timer isst_if_mbox_pci[ 7678.784496] input_leds isst_if_mmio sg snd isst_if_common soundcore wmi button sad9(O) drm fuse backlightconfigfs efivarfs ip_tables x_tables vmd sdhci led_class rtl8150 r8152 hid_generic pegasus mmc_block usbhidmmc_core hid megaraid_sas ixgb igb i2c_algo_bit ice i40e hpsa scsi_transport_sas e1000e e1000 e100 ax88179_178ausbnet xhci_pci sd_mod xhci_hcd t10_pi crc32c_intel crc64_rocksoft igc crc64 crc_t10dif usbcorecrct10dif_generic ptp crct10dif_common usb_common pps_core[ 7679.200403] RIP: 0010:dev_watchdog+0x1ae/0x1f0[ 7679.210201] Code: 28 e9 53 ff ff ff 4c 89 e7 c6 05 06 42 b9 00 01 e8 17 d1 fb ff 44 89 e9 4c89 e6 48 c7 c7 40 ad fb 81 48 89 c2 e8 52 62 82 ff <0f> 0b e9 72 ff ff ff 65 8b 05 80 7d 7c 7e89 c0 48 0f a3 05 0a c1[ 7679.245438] RSP: 0018:ffa00000001f7d90 EFLAGS: 00010282[ 7679.256021] RAX: 0000000000000000 RBX: ff11000109938440 RCX: 0000000000000000[ 7679.268710] RDX: ff11000361e26cd8 RSI: ff11000361e1b880 RDI: ff11000361e1b880[ 7679.281314] RBP: ffa00000001f7da8 R08: ff1100035f8fffe8 R09: 0000000000027ffb[ 7679.293840] R10: 0000000000001f0a R11: ff1100035f840000 R12: ff11000109938000[ 7679.306276] R13: 0000000000000002 R14: dead000000000122 R15: ffa00000001f7e18[ 7679.318648] FS: 0000000000000000(0000) GS:ff11000361e00000(0000) knlGS:0000000000000000[ 7679.332064] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 7679.342757] CR2: 00007ffff7fca168 CR3: 000000013b08a006 CR4: 0000000000471ef8[ 7679.354984] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 7679.367207] DR3: 0000000000000000 DR6: 00000000fffe07f0 DR7: 0000000000000400[ 7679.379370] PKRU: 55555554[ 7679.386446] Call Trace:[ 7679.393152] [ 7679.399363] ? __pfx_dev_watchdog+0x10/0x10[ 7679.407870] call_timer_fn+0x31/0x110[ 7679.415698] e---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix lockdep splat and potential deadlock after failure running delayed itemsWhen running delayed items we are holding a delayed node's mutex and thenwe will attempt to modify a subvolume btree to insert/update/delete thedelayed items. However if have an error during the insertions for example,btrfs_insert_delayed_items() may return with a path that has locked extentbuffers (a leaf at the very least), and then we attempt to release thedelayed node at __btrfs_run_delayed_items(), which requires taking thedelayed node's mutex, causing an ABBA type of deadlock.

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.

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

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: verify orphan file size is not too bigIn principle orphan file can be arbitrarily large. However orphan replayneeds to traverse it all and we also pin all its buffers in memory. Thusfilesystems with absurdly large orphan files can lead to big amounts ofmemory consumed. Limit orphan file size to a sane value and also usekvmalloc() for allocating array of block descriptor structures to avoidlarge order allocations for sane but large orphan files.

Description: In the Linux kernel, the following vulnerability has been resolved:cpufreq: intel_pstate: Fix object lifecycle issue in update_qos_request()The cpufreq_cpu_put() call in update_qos_request() takes place too earlybecause the latter subsequently calls freq_qos_update_request() thatindirectly accesses the policy object in question through the QoS requestobject passed to it.Fortunately, update_qos_request() is called under intel_pstate_driver_lock,so this issue does not matter for changing the intel_pstate operationmode, but it theoretically can cause a crash to occur on CPU device hotremoval (which currently can only happen in virt, but it is formallysupported nevertheless).Address this issue by modifying update_qos_request() to drop thereference to the policy later.

CVE-2025-68746 Severity: Moderate CVSS3 score: 4.7

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:net: core: prevent NULL deref in generic_hwtstamp_ioctl_lower()The ethtool tsconfig Netlink path can trigger a null pointerdereference. A call chain such as: tsconfig_prepare_data() -> dev_get_hwtstamp_phylib() -> vlan_hwtstamp_get() -> generic_hwtstamp_get_lower() -> generic_hwtstamp_ioctl_lower()results in generic_hwtstamp_ioctl_lower() being called withkernel_cfg->ifr as NULL.The generic_hwtstamp_ioctl_lower() function does not expecta NULL ifr and dereferences it, leading to a system crash.Fix this by adding a NULL check for kernel_cfg->ifr ingeneric_hwtstamp_ioctl_lower().

Description: In the Linux kernel, the following vulnerability has been resolved:can: gs_usb: gs_usb_receive_bulk_callback(): fix URB memory leakIn gs_can_open(), the URBs for USB-in transfers are allocated, added to theparent->rx_submitted anchor and submitted. In the complete callbackgs_usb_receive_bulk_callback(), the URB is processed and resubmitted. Ings_can_close() the URBs are freed by callingusb_kill_anchored_urbs(parent->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 gs_can_close().Fix the memory leak by anchoring the URB in thegs_usb_receive_bulk_callback() to the parent->rx_submitted anchor.

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-2023-54225 Severity: Moderate CVSS3 score: 4.1

Description: In the Linux kernel, the following vulnerability has been resolved:net: ipa: only reset hashed tables when supportedLast year, the code that manages GSI channel transactions switchedfrom using spinlock-protected linked lists to using indexes into thering buffer used for a channel. Recently, Google reported seeingtransaction reference count underflows occasionally during shutdown.Doug Anderson found a way to reproduce the issue reliably, andbisected the issue to the commit that eliminated the linked listsand the lock. The root cause was ultimately determined to berelated to unused transactions being committed as part of the modemshutdown cleanup activity. Unused transactions are not normallyexpected (except in error cases).The modem uses some ranges of IPA-resident memory, and whenever itshuts down we zero those ranges. In ipa_filter_reset_table() atransaction is allocated to zero modem filter table entries. Ifhashing is not supported, hashed table memory should not be zeroed.But currently nothing prevents that, and the result is an unusedtransaction. Something similar occurs when we zero routing tableentries for the modem.By preventing any attempt to clear hashed tables when hashing is notsupported, the reference count underflow is avoided in this case.Note that there likely remains an issue with properly freeing unusedtransactions (if they occur due to errors). This patch addressesonly the underflows that Google originally reported.

The field is initialized byioc_pd_init() and never cleared. The NULL deref is caused byblkcg_activate_policy() installing blkg_policy_data before initializing it.blkcg_activate_policy() was doing the following:1. Allocate pd's for all existing blkg's and install them in blkg->pd[].2. Initialize all pd's.3. Online all pd's.blkcg_activate_policy() only grabs the queue_lock and may release andre-acquire the lock as allocation may need to sleep. ioc_weight_write()grabs blkcg->lock and iterates all its blkg's. The two can race and ifioc_weight_write() runs during #1 or between #1 and #2, it can encounter apd which is not initialized yet, leading to crash.The crash can be reproduced with the following script: #!/bin/bash echo +io > /sys/fs/cgroup/cgroup.subtree_control systemd-run --unit touch-sda --scope dd if=/dev/sda of=/dev/null bs=1M count=1 iflag=direct echo 100 > /sys/fs/cgroup/system.slice/io.weight bash -c "echo '8:0 enable=1' > /sys/fs/cgroup/io.cost.qos" & sleep .2 echo 100 > /sys/fs/cgroup/system.slice/io.weightwith the following patch applied:> diff --git a/block/blk-cgroup.c b/block/blk-cgroup.c> index fc49be622e05..38d671d5e10c 100644> --- a/block/blk-cgroup.c> +++ b/block/blk-cgroup.c> @@ -1553,6 +1553,12 @@ int blkcg_activate_policy(struct gendisk *disk, const struct blkcg_policy *pol)> pd->online = false;> }>> + if (system_state == SYSTEM_RUNNING) {> + spin_unlock_irq(&q->queue_lock);> + ssleep(1);> + spin_lock_irq(&q->queue_lock);> + }> +> /* all allocated, init in the same order */> if (pol->pd_init_fn)> list_for_each_entry_reverse(blkg, &q->blkg_list, q_node)I don't see a reason why all pd's should be allocated, initialized andonlined together. The only ordering requirement is that parent blkgs to beinitialized and onlined before children, which is guaranteed from thewalking order. Let's fix the bug by allocating, initializing and onlining pdfor each blkg and holding blkcg->lock over initialization and onlining. Thisensures that an installed blkg is always fully initialized and onlinedremoving the the race window.

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

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.

If L1 (or host userspace) modifies the I/O permissionbitmaps during the exit to userspace, KVM will treat the access as beingintercepted despite already having emulated the I/O access.Pivot on EMULTYPE_NO_DECODE to detect that KVM is completing emulation.Of the three users of EMULTYPE_NO_DECODE, only complete_emulated_io() (theintended "recipient") can reach the code in question. gp_interception()'suse is mutually exclusive with is_guest_mode(), andcomplete_emulated_insn_gp() unconditionally pairs EMULTYPE_NO_DECODE withEMULTYPE_SKIP.The bad behavior was detected by a syzkaller program that toggles port I/Ointerception during the userspace I/O exit, ultimately resulting in a WARNon vcpu->arch.pio.count being non-zero due to KVM no completing emulationof the I/O instruction.

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

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

The string argument must be a well-formed MAC-48 address in one of the supported formats, but this requirement has been poorly documented.

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

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

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

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

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

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

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-2025-8291 Severity: Low CVSS3 score: 3.3

Description: The 'zipfile' module would not check the validity of the ZIP64 End ofCentral Directory (EOCD) Locator record offset value would not be used tolocate the ZIP64 EOCD record, instead the ZIP64 EOCD record would beassumed to be the previous record in the ZIP archive. This could be abusedto create ZIP archives that are handled differently by the 'zipfile' modulecompared to other ZIP implementations.Remediation maintains this behavior, but checks that the offset specifiedin the ZIP64 EOCD Locator record matches the expected value.

CVE-2025-8732 Severity: Low CVSS3 score: 3.3

Description: A vulnerability was found in libxml2 up to 2.14.5. It has been declared as problematic. This vulnerability affects the function xmlParseSGMLCatalog of the component xmlcatalog. The manipulation leads to uncontrolled recursion. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. The code maintainer explains, that "[t]he issue can only be triggered with untrusted SGML catalogs and it makes absolutely no sense to use untrusted catalogs. I also doubt that anyone is still using SGML catalogs at all."

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

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

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

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

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

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

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

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.
