CVE-2024-38610 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:drivers/virt/acrn: fix PFNMAP PTE checks in acrn_vm_ram_map()Patch series "mm: follow_pte() improvements and acrn follow_pte() fixes".Patch #1 fixes a bunch of issues I spotted in the acrn driver. Itcompiles, that's all I know. I'll appreciate some review and testing fromacrn folks.Patch #2+#3 improve follow_pte(), passing a VMA instead of the MM, addingmore sanity checks, and improving the documentation. Gave it a quick teston x86-64 using VM_PAT that ends up using follow_pte().This patch (of 3):We currently miss handling various cases, resulting in a dangerousfollow_pte() (previously follow_pfn()) usage.(1) We're not checking PTE write permissions.Maybe we should simply always require pte_write() like we do forpin_user_pages_fast(FOLL_WRITE)? Hard to tell, so let's check forACRN_MEM_ACCESS_WRITE for now.(2) We're not rejecting refcounted pages.As we are not using MMU notifiers, messing with refcounted pages isdangerous and can result in use-after-free. Let's make sure to reject them.(3) We are only looking at the first PTE of a bigger range.We only lookup a single PTE, but memmap->len may span a larger area.Let's loop over all involved PTEs and make sure the PFN range isactually contiguous. Reject everything else: it couldn't have workedeither way, and rather made use access PFNs we shouldn't be accessing.

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

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

CVE-2025-56005 Severity: Important CVSS3 score: 7.8

Description: An undocumented and unsafe feature in the PLY (Python Lex-Yacc) library 3.11 allows Remote Code Execution (RCE) via the `picklefile` parameter in the `yacc()` function. This parameter accepts a `.pkl` file that is deserialized with `pickle.load()` without validation. Because `pickle` allows execution of embedded code via `__reduce__()`, an attacker can achieve code execution by passing a malicious pickle file. The parameter is not mentioned in official documentation or the GitHub repository, yet it is active in the PyPI version. This introduces a stealthy backdoor and persistence risk.

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-2025-13601 Severity: Important CVSS3 score: 7.7

Description: A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string.

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-2025-30204 Severity: Important CVSS3 score: 7.5

Description: golang-jwt is a Go implementation of JSON Web Tokens. Starting in version 3.2.0 and prior to versions 5.2.2 and 4.5.2, the function parse.ParseUnverified splits (via a call to strings.Split) its argument (which is untrusted data) on periods. As a result, in the face of a malicious request whose Authorization header consists of Bearer followed by many period characters, a call to that function incurs allocations to the tune of O(n) bytes (where n stands for the length of the function's argument), with a constant factor of about 16. This issue is fixed in 5.2.2 and 4.5.2.

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

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

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

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

Description: AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below allow for an infinite loop to occur when assert statements are bypassed, resulting in a DoS attack when processing a POST body. If optimizations are enabled (-O or PYTHONOPTIMIZE=1), and the application includes a handler that uses the Request.post() method, then an attacker may be able to execute a DoS attack with a specially crafted message.

CVE-2025-69229 Severity: Important CVSS3 score: 7.5

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

Description: 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.

CVE-2024-35843 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:iommu/vt-d: Use device rbtree in iopf reporting pathThe existing I/O page fault handler currently locates the PCI device bycalling pci_get_domain_bus_and_slot(). This function searches the listof all PCI devices until the desired device is found. To improve lookupefficiency, replace it with device_rbtree_find() to search the devicewithin the probed device rbtree.The I/O page fault is initiated by the device, which does not have anysynchronization mechanism with the software to ensure that the devicestays in the probed device tree. Theoretically, a device could be releasedby the IOMMU subsystem after device_rbtree_find() and beforeiopf_get_dev_fault_param(), which would cause a use-after-free problem.Add a mutex to synchronize the I/O page fault reporting path and the IOMMUrelease device path. This lock doesn't introduce any performance overhead,as the conflict between I/O page fault reporting and device releasing isvery rare.

CVE-2024-36899 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:gpiolib: cdev: Fix use after free in lineinfo_changed_notifyThe use-after-free issue occurs as follows: when the GPIO chip device fileis being closed by invoking gpio_chrdev_release(), watched_lines is freedby bitmap_free(), but the unregistration of lineinfo_changed_nb notifierchain failed due to waiting write rwsem. Additionally, one of the GPIOchip's lines is also in the release process and holds the notifier chain'sread rwsem. Consequently, a race condition leads to the use-after-free ofwatched_lines.Here is the typical stack when issue happened:[free]gpio_chrdev_release() --> bitmap_free(cdev->watched_lines) <-- freed --> blocking_notifier_chain_unregister() --> down_write(&nh->rwsem) <-- waiting rwsem --> __down_write_common() --> rwsem_down_write_slowpath() --> schedule_preempt_disabled() --> schedule()[use]st54spi_gpio_dev_release() --> gpio_free() --> gpiod_free() --> gpiod_free_commit() --> gpiod_line_state_notify() --> blocking_notifier_call_chain() --> down_read(&nh->rwsem); <-- held rwsem --> notifier_call_chain() --> lineinfo_changed_notify() --> test_bit(xxxx, cdev->watched_lines) <-- use after freeThe side effect of the use-after-free issue is that a GPIO line event isbeing generated for userspace where it shouldn't. However, since the chrdevis being closed, userspace won't have the chance to read that event anyway.To fix the issue, call the bitmap_free() function after the unregistrationof lineinfo_changed_nb notifier chain.

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix __dst_negative_advice() race__dst_negative_advice() does not enforce proper RCU rules whensk->dst_cache must be cleared, leading to possible UAF.RCU rules are that we must first clear sk->sk_dst_cache,then call dst_release(old_dst).Note that sk_dst_reset(sk) is implementing this protocol correctly,while __dst_negative_advice() uses the wrong order.Given that ip6_negative_advice() has special logicagainst RTF_CACHE, this means each of the three ->negative_advice()existing methods must perform the sk_dst_reset() themselves.Note the check against NULL dst is centralized in__dst_negative_advice(), there is no need to duplicateit in various callbacks.Many thanks to Clement Lecigne for tracking this issue.This old bug became visible after the blamed commit, using UDP sockets.

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(). A READ_ONCE on futex_q::task beforefutex_requeue_pi_complete() is enough because it ensures that the variableis read before the state is updated.Read futex_q::task before updating the requeue state, use it for thefollowing wakeup.

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.

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

CVE-2025-71089 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 didn't take the bast callbacks forasynchronous lock contention notifications into account, which remainactive until until a lock is unlocked or its lockspace is released.To prevent those callbacks from accessing deallocated objects, put theglocks that should not be unlocked on the sd_dead_glocks list, releasethe lockspace, and only then free those glocks.As an additional measure, ignore unexpected ast and bast callbacks ifthe receiving glock is dead.

CVE-2025-68801 Severity: Moderate CVSS3 score: 6.7

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

CVE-2025-67499 Severity: Moderate CVSS3 score: 6.6

Description: The CNI portmap plugin allows containers to emulate opening a host port, forwarding that traffic to the container. Versions 1.6.0 through 1.8.0 inadvertently forward all traffic with the same destination port as the host port when the portmap plugin is configured with the nftables backend, thus ignoring the destination IP. This includes traffic not intended for the node itself, i.e. traffic to containers hosted on the node. Containers that request HostPort forwarding can intercept all traffic destined for that port. This requires that the portmap plugin be explicitly configured to use the nftables backend. This issue is fixed in version 1.9.0. To workaround, configure the portmap plugin to use the iptables backend. It does not have this vulnerability.

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.

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).

Since the periodic timer does not require frequent APICtimer register programming, the guest may continue to use the softwaretimer in ---truncated---

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!

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: qla2xxx: Fix improper freeing of purex itemIn qla2xxx_process_purls_iocb(), an item is allocated viaqla27xx_copy_multiple_pkt(), which internally callsqla24xx_alloc_purex_item().The qla24xx_alloc_purex_item() function may return a pre-allocated itemfrom a per-adapter pool for small allocations, instead of dynamicallyallocating memory with kzalloc().An error handling path in qla2xxx_process_purls_iocb() incorrectly useskfree() to release the item. If the item was from the pre-allocatedpool, calling kfree() on it is a bug that can lead to memory corruption.Fix this by using the correct deallocation function,qla24xx_free_purex_item(), which properly handles both dynamicallyallocated and pre-allocated items.

CVE-2025-68768 Severity: Moderate CVSS3 score: 5.9

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

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

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

[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.

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:iavf: fix off-by-one issues in iavf_config_rss_reg()There are off-by-one bugs when configuring RSS hash key and lookuptable, causing out-of-bounds reads to memory [1] and out-of-boundswrites to device registers.Before commit 43a3d9ba34c9 ("i40evf: Allow PF driver to configure RSS"),the loop upper bounds were: i <= I40E_VFQF_{HKEY,HLUT}_MAX_INDEXwhich is safe since the value is the last valid index.That commit changed the bounds to: i <= adapter->rss_{key,lut}_size / 4where `rss_{key,lut}_size / 4` is the number of dwords, so the lastvalid index is `(rss_{key,lut}_size / 4) - 1`. 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-2025-71102 Severity: Moderate CVSS3 score: 5.6

Description: In the Linux kernel, the following vulnerability has been resolved:scs: fix a wrong parameter in __scs_magic__scs_magic() needs a 'void *' variable, but a 'struct task_struct *' isgiven. 'task_scs(tsk)' is the starting address of the task's shadow callstack, and '__scs_magic(task_scs(tsk))' is the end address of the task'sshadow call stack. Here should be '__scs_magic(task_scs(tsk))'.The user-visible effect of this bug is that when CONFIG_DEBUG_STACK_USAGEis enabled, the shadow call stack usage checking function(scs_check_usage) would scan an incorrect memory range. This could lead1. **Inaccurate stack usage reporting**: The function would calculate wrong usage statistics for the shadow call stack, potentially showing incorrect value in kmsg.2. **Potential kernel crash**: If the value of __scs_magic(tsk)is greater than that of __scs_magic(task_scs(tsk)), the for loop may access unmapped memory, potentially causing a kernel panic. However, this scenario is unlikely because task_struct is allocated via the slab allocator (which typically returns lower addresses), while the shadow call stack returned by task_scs(tsk) is allocated via vmalloc(which typically returns higher addresses).However, since this is purely a debugging feature(CONFIG_DEBUG_STACK_USAGE), normal production systems should be notunaffected. The bug only impacts developers and testers who are activelydebugging stack usage with this configuration enabled.

All these areprotected by a test skb->protocol == ETH_P_802_2. Which does notprotect against this tun scenario.But the mac_len test added in this patch in llc_fixup_skb willindirectly protect those too. That is called from llc_rcv before anyother LLC code.It is tempting to just add a blanket mac_len check in llc_rcv, butnot sure whether that could break valid LLC paths that do not assumean Ethernet header. 802.2 LLC may be used on top of non-802.3protocols in principle. The below referenced commit shows that usedto, on top of Token Ring.At least one of the three eth_hdr uses goes back to before the startof git history. But the one that syzbot exercises is introduced inthis commit. That commit is old enough (2008), that effectively allstable kernels should receive this.

CVE-2023-54172 Severity: Moderate CVSS3 score: 5.5

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.

CVE-2024-26676 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:af_unix: Call kfree_skb() for dead unix_(sk)->oob_skb in GC.syzbot reported a warning [0] in __unix_gc() with a repro, whichcreates a socketpair and sends one socket's fd to itself using thepeer. socketpair(AF_UNIX, SOCK_STREAM, 0, [3, 4]) = 0 sendmsg(4, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\360", iov_len=1}], msg_iovlen=1, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_type=SCM_RIGHTS, cmsg_data=[3]}], msg_controllen=24, msg_flags=0}, MSG_OOB|MSG_PROBE|MSG_DONTWAIT|MSG_ZEROCOPY) = 1This forms a self-cyclic reference that GC should finally untanglebut does not due to lack of MSG_OOB handling, resulting in memoryleak.Recently, commit 11498715f266 ("af_unix: Remove io_uring code forGC.") removed io_uring's dead code in GC and revealed the problem.The code was executed at the final stage of GC and unconditionallymoved all GC candidates from gc_candidates to gc_inflight_list.That papered over the reported problem by always making the followingWARN_ON_ONCE(!list_empty(&gc_candidates)) false.The problem has been there since commit 2aab4b969002 ("af_unix: fixstruct pid leaks in OOB support") added full scm support for MSG_OOBwhile fixing another bug.To fix this problem, we must call kfree_skb() for unix_sk(sk)->oob_skbif the socket still exists in gc_candidates after purging collected skb.Then, we need to set NULL to oob_skb before calling kfree_skb() becauseit calls last fput() and triggers unix_release_sock(), where we callduplicate kfree_skb(u->oob_skb) if not NULL.Note that the leaked socket remained being linked to a global list, sokmemleak also could not detect it. We need to check /proc/net/protocolto notice the unfreed socket.[0]:WARNING: CPU: 0 PID: 2863 at net/unix/garbage.c:345 __unix_gc+0xc74/0xe80 net/unix/garbage.c:345Modules linked in:CPU: 0 PID: 2863 Comm: kworker/u4:11 Not tainted 6.8.0-rc1-syzkaller-00583-g1701940b1a02 #0Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/25/2024Workqueue: events_unbound __unix_gcRIP: 0010:__unix_gc+0xc74/0xe80 net/unix/garbage.c:345Code: 8b 5c 24 50 e9 86 f8 ff ff e8 f8 e4 22 f8 31 d2 48 c7 c6 30 6a 69 89 4c 89 ef e8 97 ef ff ff e9 80 f9 ff ff e8 dd e4 22 f8 90 <0f> 0b 90 e9 7b fd ff ff 48 89 df e8 5c e7 7c f8 e9 d3 f8 ff ff e8RSP: 0018:ffffc9000b03fba0 EFLAGS: 00010293RAX: 0000000000000000 RBX: ffffc9000b03fc10 RCX: ffffffff816c493eRDX: ffff88802c02d940 RSI: ffffffff896982f3 RDI: ffffc9000b03fb30RBP: ffffc9000b03fce0 R08: 0000000000000001 R09: fffff52001607f66R10: 0000000000000003 R11: 0000000000000002 R12: dffffc0000000000R13: ffffc9000b03fc10 R14: ffffc9000b03fc10 R15: 0000000000000001FS: 0000000000000000(0000) GS:ffff8880b9400000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00005559c8677a60 CR3: 000000000d57a000 CR4: 00000000003506f0DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400Call Trace: process_one_work+0x889/0x15e0 kernel/workqueue.c:2633 process_scheduled_works kernel/workqueue.c:2706 [inline] worker_thread+0x8b9/0x12a0 kernel/workqueue.c:2787 kthread+0x2c6/0x3b0 kernel/kthread.c:388 ret_from_fork+0x45/0x80 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1b/0x30 arch/x86/entry/entry_64.S:242

CVE-2024-35247 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fpga: region: add owner module and take its refcountThe current implementation of the fpga region assumes that the low-levelmodule registers a driver for the parent device and uses its owner pointerto take the module's refcount. This approach is problematic since it canlead to a null pointer dereference while attempting to get the regionduring programming if the parent device does not have a driver.To address this problem, add a module owner pointer to the fpga_regionstruct and use it to take the module's refcount. Modify the functions forregistering a region to take an additional owner module parameter andrename them to avoid conflicts. Use the old function names for helpermacros that automatically set the module that registers the region as theowner. This ensures compatibility with existing low-level control modulesand reduces the chances of registering a region without setting the owner.Also, update the documentation to keep it consistent with the new interfacefor registering an fpga region.

CVE-2024-35807 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: fix corruption during on-line resizeWe observed a corruption during on-line resize of a file system that islarger than 16 TiB with 4k block size. With having more then 2^32 blocksresize_inode is turned off by default by mke2fs. The issue can bereproduced on a smaller file system for convenience by explicitlyturning off resize_inode. An on-line resize across an 8 GiB boundary (thesize of a meta block group in this setup) then leads to a corruption: dev=/dev/ # should be >= 16 GiB mkdir -p /corruption /sbin/mke2fs -t ext4 -b 4096 -O ^resize_inode $dev $((2 * 2**21 - 2**15)) mount -t ext4 $dev /corruption dd if=/dev/zero bs=4096 of=/corruption/test count=$((2*2**21 - 4*2**15)) sha1sum /corruption/test # 79d2658b39dcfd77274e435b0934028adafaab11 /corruption/test /sbin/resize2fs $dev $((2*2**21)) # drop page cache to force reload the block from disk echo 1 > /proc/sys/vm/drop_caches sha1sum /corruption/test # 3c2abc63cbf1a94c9e6977e0fbd72cd832c4d5c3 /corruption/test2^21 = 2^15*2^6 equals 8 GiB whereof 2^15 is the number of blocks perblock group and 2^6 are the number of block groups that make a metablock group.The last checksum might be different depending on how the file is laidout across the physical blocks. The actual corruption occurs at physicalblock 63*2^15 = 2064384 which would be the location of the backup of themeta block group's block descriptor. During the on-line resize the filesystem will be converted to meta_bg starting at s_first_meta_bg which is2 in the example - meaning all block groups after 16 GiB. However, inext4_flex_group_add we might add block groups that are not part of thefirst meta block group yet. In the reproducer we achieved this bysubstracting the size of a whole block group from the point where themeta block group would start. This must be considered when updating thebackup block group descriptors to follow the non-meta_bg layout. The fixis to add a test whether the group to add is already part of the metablock group or not.

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring/net: fix overflow check in io_recvmsg_mshot_prep()The "controllen" variable is type size_t (unsigned long). Casting itto int could lead to an integer underflow.The check_add_overflow() function considers the type of the destinationwhich is type int. If we add two positive values and the result cannotfit in an integer then that's counted as an overflow.However, if we cast "controllen" to an int and it turns negative, thennegative values *can* fit into an int type so there is no overflow.Good: 100 + (unsigned long)-4 = 96 <-- overflow Bad: 100 + (int)-4 = 96 <-- no overflowI deleted the cast of the sizeof() as well. That's not a bug but thecast is unnecessary.

CVE-2024-35884 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:udp: do not accept non-tunnel GSO skbs landing in a tunnelWhen rx-udp-gro-forwarding is enabled UDP packets might be GROed whenbeing forwarded. If such packets might land in a tunnel this can causevarious issues and udp_gro_receive makes sure this isn't the case bylooking for a matching socket. This is performed inudp4/6_gro_lookup_skb but only in the current netns. This is an issuewith tunneled packets when the endpoint is in another netns. In suchcases the packets will be GROed at the UDP level, which leads to variousissues later on. The same thing can happen with rx-gro-list.We saw this with geneve packets being GROed at the UDP level. In suchcase gso_size is set; later the packet goes through the geneve rx path,the geneve header is pulled, the offset are adjusted and frag_list skbsare not adjusted with regard to geneve. When those skbs hitskb_fragment, it will misbehave. Different outcomes are possibledepending on what the GROed skbs look like; from corrupted packets tokernel crashes.One example is a BUG_ON[1] triggered in skb_segment while processing thefrag_list. Because gso_size is wrong (geneve header was pulled)skb_segment thinks there is "geneve header size" of data in frag_list,although it's in fact the next packet. The BUG_ON itself has nothing todo with the issue. This is only one of the potential issues.Looking up for a matching socket in udp_gro_receive is fragile: thelookup could be extended to all netns (not speaking about performances)but nothing prevents those packets from being modified in between and wecould still not find a matching socket. It's OK to keep the currentlogic there as it should cover most cases but we also need to make surewe handle tunnel packets being GROed too early.This is done by extending the checks in udp_unexpected_gso: GSO packetslacking the SKB_GSO_UDP_TUNNEL/_CSUM bits and landing in a tunnel mustbe segmented.[1] kernel BUG at net/core/skbuff.c:4408!

CVE-2024-35970 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:af_unix: Clear stale u->oob_skb.syzkaller started to report deadlock of unix_gc_lock after commit4090fa373f0e ("af_unix: Replace garbage collection algorithm."), butit just uncovers the bug that has been there since commit 314001f0bf92("af_unix: Add OOB support").The repro basically does the following. from socket import * from array import array c1, c2 = socketpair(AF_UNIX, SOCK_STREAM) c1.sendmsg([b'a'], [(SOL_SOCKET, SCM_RIGHTS, array("i", [c2.fileno()]))], MSG_OOB) c2.recv(1) # blocked as no normal data in recv queue c2.close() # done async and unblock recv() c1.close() # done async and trigger GCA socket sends its file descriptor to itself as OOB data and tries toreceive normal data, but finally recv() fails due to async close().The problem here is wrong handling of OOB skb in manage_oob(). Whenrecvmsg() is called without MSG_OOB, manage_oob() is called to checkif the peeked skb is OOB skb. In such a case, manage_oob() pops itout of the receive queue but does not clear unix_sock(sk)->oob_skb.This is wrong in terms of uAPI.Let's say we send "hello" with MSG_OOB, and "world" without MSG_OOB.The 'o' is handled as OOB data. When recv() is called twice withoutMSG_OOB, the OOB data should be lost. >>> from socket import * >>> c1, c2 = socketpair(AF_UNIX, SOCK_STREAM, 0) >>> c1.send(b'hello', MSG_OOB) # 'o' is OOB data 5 >>> c1.send(b'world') 5 >>> c2.recv(5) # OOB data is not received b'hell' >>> c2.recv(5) # OOB date is skipped b'world' >>> c2.recv(5, MSG_OOB) # This should return an error b'o'In the same situation, TCP actually returns -EINVAL for the lastrecv().Also, if we do not clear unix_sk(sk)->oob_skb, unix_poll() always setEPOLLPRI even though the data has passed through by previous recv().To avoid these issues, we must clear unix_sk(sk)->oob_skb when dequeuingit from recv queue.The reason why the old GC did not trigger the deadlock is because theold GC relied on the receive queue to detect the loop.When it is triggered, the socket with OOB data is marked as GC candidatebecause file refcount == inflight count (1). However, after traversingall inflight sockets, the socket still has a positive inflight count (1),thus the socket is excluded from candidates. Then, the old GC lose thechance to garbage-collect the socket.With the old GC, the repro continues to create true garbage that willnever be freed nor detected by kmemleak as it's linked to the globalinflight list. That's why we couldn't even notice the issue.

CVE-2024-36479 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fpga: bridge: add owner module and take its refcountThe current implementation of the fpga bridge assumes that the low-levelmodule registers a driver for the parent device and uses its owner pointerto take the module's refcount. This approach is problematic since it canlead to a null pointer dereference while attempting to get the bridge ifthe parent device does not have a driver.To address this problem, add a module owner pointer to the fpga_bridgestruct and use it to take the module's refcount. Modify the function forregistering a bridge to take an additional owner module parameter andrename it to avoid conflicts. Use the old function name for a helper macrothat automatically sets the module that registers the bridge as the owner.This ensures compatibility with existing low-level control modules andreduces the chances of registering a bridge without setting the owner.Also, update the documentation to keep it consistent with the new interfacefor registering an fpga bridge.Other changes: opportunistically move put_device() from __fpga_bridge_get()to fpga_bridge_get() and of_fpga_bridge_get() to improve code clarity sincethe bridge device is taken in these functions.

Description: In the Linux kernel, the following vulnerability has been resolved:e1000e: change usleep_range to udelay in PHY mdic accessThis is a partial revert of commit 6dbdd4de0362 ("e1000e: Workaroundfor sporadic MDI error on Meteor Lake systems"). The referenced commitused usleep_range inside the PHY access routines, which are sometimescalled from an atomic context. This can lead to a kernel panic in somescenarios, such as cable disconnection and reconnection on vPro systems.Solve this by changing the usleep_range calls back to udelay.

CVE-2024-37021 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fpga: manager: add owner module and take its refcountThe current implementation of the fpga manager assumes that the low-levelmodule registers a driver for the parent device and uses its owner pointerto take the module's refcount. This approach is problematic since it canlead to a null pointer dereference while attempting to get the manager ifthe parent device does not have a driver.To address this problem, add a module owner pointer to the fpga_managerstruct and use it to take the module's refcount. Modify the functions forregistering the manager to take an additional owner module parameter andrename them to avoid conflicts. Use the old function names for helpermacros that automatically set the module that registers the manager as theowner. This ensures compatibility with existing low-level control modulesand reduces the chances of registering a manager without setting the owner.Also, update the documentation to keep it consistent with the new interfacefor registering an fpga manager.Other changes: opportunistically move put_device() from __fpga_mgr_get() tofpga_mgr_get() and of_fpga_mgr_get() to improve code clarity since themanager device is taken in these functions.

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

Description: In the Linux kernel, the following vulnerability has been resolved:iommu: Clear iommu-dma ops on cleanupIf iommu_device_register() encounters an error, it can end up tearingdown already-configured groups and default domains, however thiscurrently still leaves devices hooked up to iommu-dma (and evenhistorically the behaviour in this area was at best inconsistent acrossarchitectures/drivers...) Although in the case that an IOMMU is presentwhose driver has failed to probe, users cannot necessarily expect DMA towork anyway, it's still arguable that we should do our best to putthings back as if the IOMMU driver was never there at all, and certainlythe potential for crashing in iommu-dma itself is undesirable. Make surewe clean up the dev->dma_iommu flag along with everything else.

CVE-2025-37878 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:perf/core: Fix WARN_ON(!ctx) in __free_event() for partial initMove the get_ctx(child_ctx) call and the child_event->ctx assignment tooccur immediately after the child event is allocated. Ensure thatchild_event->ctx is non-NULL before any subsequent error path withininherit_event calls free_event(), satisfying the assumptions of thecleanup code.Details:There's no clear Fixes tag, because this bug is a side-effect ofmultiple interacting commits over time (up to 15 years old), nota single regression.The code initially incremented refcount then assigned contextimmediately after the child_event was created. Later, an earlyvalidity check for child_event was added before therefcount/assignment. Even later, a WARN_ON_ONCE() cleanup check wasadded, assuming event->ctx is valid if the pmu_ctx is valid.The problem is that the WARN_ON_ONCE() could trigger after the initialcheck passed but before child_event->ctx was assigned, violating itsprecondition. The solution is to assign child_event->ctx right afterits initial validation. This ensures the context exists for anysubsequent checks or cleanup routines, resolving the WARN_ON_ONCE().To resolve it, defer the refcount update and child_event->ctx assignmentdirectly after child_event->pmu_ctx is set but before checking if theparent event is orphaned. The cleanup routine depends onevent->pmu_ctx being non-NULL before it verifies event->ctx isnon-NULL. This also maintains the author's original intent of passingin child_ctx to find_get_pmu_context before its refcount/assignment.[ mingo: Expanded the changelog from another email by Gabriel Shahrouzi. ]

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.

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

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

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

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

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.

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.

CVE-2025-40124 Severity: Moderate CVSS3 score: 5.5

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved: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-2025-40251 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.

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.

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:bpf: Sync pending IRQ work before freeing ring bufferFix a race where irq_work can be queued in bpf_ringbuf_commit()but the ring buffer is freed before the work executes.In the syzbot reproducer, a BPF program attached to sched_switchtriggers bpf_ringbuf_commit(), queuing an irq_work. If the ring bufferis freed before this work executes, the irq_work thread may accessesfreed memory.Calling `irq_work_sync(&rb->work)` ensures that all pending irq_workcomplete before freeing the buffer.

CVE-2025-40337 Severity: Moderate CVSS3 score: 5.5

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.

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

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

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

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

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

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-2025-68209 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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

CVE-2025-68325 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.

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:ocfs2: fix kernel BUG in ocfs2_find_victim_chainsyzbot reported a kernel BUG in ocfs2_find_victim_chain() because the`cl_next_free_rec` field of the allocation chain list (next free slot inthe chain list) is 0, triggring the BUG_ON(!cl->cl_next_free_rec)condition in ocfs2_find_victim_chain() and panicking the kernel.To fix this, an if condition is introduced in ocfs2_claim_suballoc_bits(),just before calling ocfs2_find_victim_chain(), the code block in it beingexecuted when either of the following conditions is true:1. `cl_next_free_rec` is equal to 0, indicating that there are no freechains in the allocation chain list2. `cl_next_free_rec` is greater than `cl_count` (the total number ofchains in the allocation chain list)Either of them being true is indicative of the fact that there are nochains left for usage.This is addressed using ocfs2_error(), which printsthe error log for debugging purposes, rather than panicking the kernel.

Until recently the problem wentunnoticed because kernfs uses a pre-allocated bounce buffer of sizePAGE_SIZE for reading EEPROM.But commit 8ad6249c51d0 ("eeprom: at25: convert to spi-mem API")introduced an additional dynamically allocated bounce buffer whose sizeis exactly the size of the transfer, leading to a buffer overrun inthe fsl-cpm driver when that size is odd.Add the missing length parity verification and remain in 8 bit modewhen the length is not even.

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-2025-68816 Severity: Moderate CVSS3 score: 5.5

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

CVE-2025-68822 Severity: Moderate CVSS3 score: 5.5

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.

CVE-2025-68823 Severity: Moderate CVSS3 score: 5.5

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

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

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

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

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

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-2025-71130 Severity: Moderate CVSS3 score: 5.5

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

CVE-2026-0990 Severity: Moderate CVSS3 score: 5.5

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

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: sch_qfq: Fix NULL deref when deactivating inactive aggregate in qfq_reset`qfq_class->leaf_qdisc->q.qlen > 0` does not imply that the classitself is active.Two qfq_class objects may point to the same leaf_qdisc. This happenswhen:1. one QFQ qdisc is attached to the dev as the root qdisc, and2. another QFQ qdisc is temporarily referenced (e.g., via qdisc_get()/ qdisc_put()) and is pending to be destroyed, as in functiontc_new_tfilter.When packets are enqueued through the root QFQ qdisc, the sharedleaf_qdisc->q.qlen increases. At the same time, the second QFQqdisc triggers qdisc_put and qdisc_destroy: the qdisc entersqfq_reset() with its own q->q.qlen == 0, but its class's leafqdisc->q.qlen > 0. Therefore, the qfq_reset would wrongly deactivatean inactive aggregate and trigger a null-deref in qfq_deactivate_agg:[ 0.903172] BUG: kernel NULL pointer dereference, address: 0000000000000000[ 0.903571] #PF: supervisor write access in kernel mode[ 0.903860] #PF: error_code(0x0002) - not-present page[ 0.904177] PGD 10299b067 P4D 10299b067 PUD 10299c067 PMD 0[ 0.904502] Oops: Oops: 0002 [#1] SMP NOPTI[ 0.904737] CPU: 0 UID: 0 PID: 135 Comm: exploit Not tainted 6.19.0-rc3+ #2 NONE[ 0.905157] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.17.0-0-gb52ca86e094d-prebuilt.qemu.org 04/01/2014[ 0.905754] RIP: 0010:qfq_deactivate_agg (include/linux/list.h:992 (discriminator 2) include/linux/list.h:1006 (discriminator 2) net/sched/sch_qfq.c:1367 (discriminator 2) net/sched/sch_qfq.c:1393 (discriminator 2))[ 0.906046] Code: 0f 84 4d 01 00 00 48 89 70 18 8b 4b 10 48 c7 c2 ff ff ff ff 48 8b 78 08 48 d3 e2 48 21 f2 48 2b 13 48 8b 30 48 d3 ea 8b 4b 18 0Code starting with the faulting instruction=========================================== 0: 0f 84 4d 01 00 00 je 0x153 6: 48 89 70 18 mov %rsi,0x18(%rax) a: 8b 4b 10 mov 0x10(%rbx),%ecx d: 48 c7 c2 ff ff ff ff mov $0xffffffffffffffff,%rdx 14: 48 8b 78 08 mov 0x8(%rax),%rdi 18: 48 d3 e2 shl %cl,%rdx 1b: 48 21 f2 and %rsi,%rdx 1e: 48 2b 13 sub (%rbx),%rdx 21: 48 8b 30 mov (%rax),%rsi 24: 48 d3 ea shr %cl,%rdx 27: 8b 4b 18 mov 0x18(%rbx),%ecx ...[ 0.907095] RSP: 0018:ffffc900004a39a0 EFLAGS: 00010246[ 0.907368] RAX: ffff8881043a0880 RBX: ffff888102953340 RCX: 0000000000000000[ 0.907723] RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000000[ 0.908100] RBP: ffff888102952180 R08: 0000000000000000 R09: 0000000000000000[ 0.908451] R10: ffff8881043a0000 R11: 0000000000000000 R12: ffff888102952000[ 0.908804] R13: ffff888102952180 R14: ffff8881043a0ad8 R15: ffff8881043a0880[ 0.909179] FS: 000000002a1a0380(0000) GS:ffff888196d8d000(0000) knlGS:0000000000000000[ 0.909572] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 0.909857] CR2: 0000000000000000 CR3: 0000000102993002 CR4: 0000000000772ef0[ 0.910247] PKRU: 55555554[ 0.910391] Call Trace:[ 0.910527] [ 0.910638] qfq_reset_qdisc (net/sched/sch_qfq.c:357 net/sched/sch_qfq.c:1485)[ 0.910826] qdisc_reset (include/linux/skbuff.h:2195 include/linux/skbuff.h:2501 include/linux/skbuff.h:3424 include/linux/skbuff.h:3430 net/sched/sch_generic.c:1036)[ 0.911040] __qdisc_destroy (net/sched/sch_generic.c:1076)[ 0.911236] tc_new_tfilter (net/sched/cls_api.c:2447)[ 0.911447] rtnetlink_rcv_msg (net/core/rtnetlink.c:6958)[ 0.911663] ? __pfx_rtnetlink_rcv_msg (net/core/rtnetlink.c:6861)[ 0.911894] netlink_rcv_skb (net/netlink/af_netlink.c:2550)[ 0.912100] netlink_unicast (net/netlink/af_netlink.c:1319 net/netlink/af_netlink.c:1344)[ 0.912296] ? __alloc_skb (net/core/skbuff.c:706)[ 0.912484] netlink_sendmsg (net/netlink/af---truncated---

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

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

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

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

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-2024-36937 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:xdp: use flags field to disambiguate broadcast redirectWhen redirecting a packet using XDP, the bpf_redirect_map() helper will setup the redirect destination information in struct bpf_redirect_info (usingthe __bpf_xdp_redirect_map() helper function), and the xdp_do_redirect()function will read this information after the XDP program returns and passthe frame on to the right redirect destination.When using the BPF_F_BROADCAST flag to do multicast redirect to a wholemap, __bpf_xdp_redirect_map() sets the 'map' pointer in structbpf_redirect_info to point to the destination map to be broadcast. Andxdp_do_redirect() reacts to the value of this map pointer to decide whetherit's dealing with a broadcast or a single-value redirect. However, if thedestination map is being destroyed before xdp_do_redirect() is called, themap pointer will be cleared out (by bpf_clear_redirect_map()) withoutwaiting for any XDP programs to stop running. This causes xdp_do_redirect()to think that the redirect was to a single target, but the target pointeris also NULL (since broadcast redirects don't have a single target), sothis causes a crash when a NULL pointer is passed to dev_map_enqueue().To fix this, change xdp_do_redirect() to react directly to the presence ofthe BPF_F_BROADCAST flag in the 'flags' value in struct bpf_redirect_infoto disambiguate between a single-target and a broadcast redirect. And onlyread the 'map' pointer if the broadcast flag is set, aborting if that hasbeen cleared out in the meantime. This prevents the crash, while keepingthe atomic (cmpxchg-based) clearing of the map pointer itself, and withoutadding any more checks in the non-broadcast fast path.

Here is anotherdifferent caller causing the same issue because of the same reason. Sowe should protect it with sk_callback_lock read lock because the writerside in the sk_psock_drop() uses "write_lock_bh(&sk->sk_callback_lock);".To avoid errors that could happen in future, I move those two pairs oflock into the sk_psock_data_ready(), which is suggested by John Fastabend.

The root cause of the issue is that netpoll is in atomiccontext and disable_irq() is called by .ndo_poll_controller interfaceof sungem driver, however, disable_irq() might sleep. After analyzingthe implementation of fec_poll_controller(), the fec driver should havethe same issue. Due to the fec driver uses NAPI for TX completions, the.ndo_poll_controller is unnecessary to be implemented in the fec driver,so fec_poll_controller() can be safely removed.

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5: Reload only IB representors upon lag disable/enableOn lag disable, the bond IB device along with all of itsrepresentors are destroyed, and then the slaves' representors get reloaded.In case the slave IB representor load fails, the eswitch error flowunloads all representors, including ethernet representors, where thenetdevs get detached and removed from lag bond. Such flow is inaccurateas the lag driver is not responsible for loading/unloading ethernetrepresentors. Furthermore, the flow described above begins by holdinglag lock to prevent bond changes during disable flow. However, whenreaching the ethernet representors detachment from lag, the lag lock isrequired again, triggering the following deadlock:Call trace:__switch_to+0xf4/0x148__schedule+0x2c8/0x7d0schedule+0x50/0xe0schedule_preempt_disabled+0x18/0x28__mutex_lock.isra.13+0x2b8/0x570__mutex_lock_slowpath+0x1c/0x28mutex_lock+0x4c/0x68mlx5_lag_remove_netdev+0x3c/0x1a0 [mlx5_core]mlx5e_uplink_rep_disable+0x70/0xa0 [mlx5_core]mlx5e_detach_netdev+0x6c/0xb0 [mlx5_core]mlx5e_netdev_change_profile+0x44/0x138 [mlx5_core]mlx5e_netdev_attach_nic_profile+0x28/0x38 [mlx5_core]mlx5e_vport_rep_unload+0x184/0x1b8 [mlx5_core]mlx5_esw_offloads_rep_load+0xd8/0xe0 [mlx5_core]mlx5_eswitch_reload_reps+0x74/0xd0 [mlx5_core]mlx5_disable_lag+0x130/0x138 [mlx5_core]mlx5_lag_disable_change+0x6c/0x70 [mlx5_core] // hold ldev->lockmlx5_devlink_eswitch_mode_set+0xc0/0x410 [mlx5_core]devlink_nl_cmd_eswitch_set_doit+0xdc/0x180genl_family_rcv_msg_doit.isra.17+0xe8/0x138genl_rcv_msg+0xe4/0x220netlink_rcv_skb+0x44/0x108genl_rcv+0x40/0x58netlink_unicast+0x198/0x268netlink_sendmsg+0x1d4/0x418sock_sendmsg+0x54/0x60__sys_sendto+0xf4/0x120__arm64_sys_sendto+0x30/0x40el0_svc_common+0x8c/0x120do_el0_svc+0x30/0xa0el0_svc+0x20/0x30el0_sync_handler+0x90/0xb8el0_sync+0x160/0x180Thus, upon lag enable/disable, load and unload only the IB representorsof the slaves preventing the deadlock mentioned above.While at it, refactor the mlx5_esw_offloads_rep_load() function to havea static helper method for its internal logic, in symmetry with therepresentor unload design.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amdgpu: Fix buffer size in gfx_v9_4_3_init_ cp_compute_microcode() and rlc_microcode()The function gfx_v9_4_3_init_microcode in gfx_v9_4_3.c was generatingabout potential truncation of output when using the snprintf function.The issue was due to the size of the buffer 'ucode_prefix' being toosmall to accommodate the maximum possible length of the string beingwritten into it.The string being written is "amdgpu/%s_mec.bin" or "amdgpu/%s_rlc.bin",where %s is replaced by the value of 'chip_name'. The length of thisstring without the %s is 16 characters. The warning message indicatedthat 'chip_name' could be up to 29 characters long, resulting in a totalof 45 characters, which exceeds the buffer size of 30 characters.To resolve this issue, the size of the 'ucode_prefix' buffer has beenreduced from 30 to 15. This ensures that the maximum possible length ofthe string being written into the buffer will not exceed its size, thuspreventing potential buffer overflow and truncation issues.Fixes the below with gcc W=1:drivers/gpu/drm/amd/amdgpu/gfx_v9_4_3.c: In function 'gfx_v9_4_3_early_init':drivers/gpu/drm/amd/amdgpu/gfx_v9_4_3.c:379:52: warning: '%s' directive output may be truncated writing up to 29 bytes into a region of size 23 [-Wformat-truncation=] 379 | snprintf(fw_name, sizeof(fw_name), "amdgpu/%s_rlc.bin", chip_name); | ^~...... 439 | r = gfx_v9_4_3_init_rlc_microcode(adev, ucode_prefix); | ~~~~~~~~~~~~drivers/gpu/drm/amd/amdgpu/gfx_v9_4_3.c:379:9: note: 'snprintf' output between 16 and 45 bytes into a destination of size 30 379 | snprintf(fw_name, sizeof(fw_name), "amdgpu/%s_rlc.bin", chip_name); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~drivers/gpu/drm/amd/amdgpu/gfx_v9_4_3.c:413:52: warning: '%s' directive output may be truncated writing up to 29 bytes into a region of size 23 [-Wformat-truncation=] 413 | snprintf(fw_name, sizeof(fw_name), "amdgpu/%s_mec.bin", chip_name); | ^~...... 443 | r = gfx_v9_4_3_init_cp_compute_microcode(adev, ucode_prefix); | ~~~~~~~~~~~~drivers/gpu/drm/amd/amdgpu/gfx_v9_4_3.c:413:9: note: 'snprintf' output between 16 and 45 bytes into a destination of size 30 413 | snprintf(fw_name, sizeof(fw_name), "amdgpu/%s_mec.bin", chip_name); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

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.

Theproblem is reproducible on the Renesas RZ/G3S SoC starting with theaddition of module stop in the clock enable/disable APIs. With module stopfunctionality enabled, a bus error is expected if a master accesses amodule whose clock has been stopped and module stop activated.Disable the IP clocks at the end of remove.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: qla2xxx: Clear cmds after chip resetCommit aefed3e5548f ("scsi: qla2xxx: target: Fix offline port handlingand host reset handling") caused two problems:1. Commands sent to FW, after chip reset got stuck and never freed as FW is not going to respond to them anymore.2. BUG_ON(cmd->sg_mapped) in qlt_free_cmd(). Commit 26f9ce53817a ("scsi: qla2xxx: Fix missed DMA unmap for aborted commands") attempted to fix this, but introduced another bug under different circumstances when two different CPUs were racing to call qlt_unmap_sg() at the same time: BUG_ON(!valid_dma_direction(dir)) in dma_unmap_sg_attrs().So revert "scsi: qla2xxx: Fix missed DMA unmap for aborted commands" andpartially revert "scsi: qla2xxx: target: Fix offline port handling andhost reset handling" at __qla2x00_abort_all_cmds.

CVE-2025-68756 Severity: Moderate CVSS3 score: 4.7

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.

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

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

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

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:iommu/mediatek: fix use-after-free on probe deferralThe driver is dropping the references taken to the larb devices duringprobe after successful lookup as well as on errors.

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:vfio/fsl-mc: Block calling interrupt handler without triggerThe eventfd_ctx trigger pointer of the vfio_fsl_mc_irq object isinitially NULL and may become NULL if the user sets the triggereventfd to -1. The interrupt handler itself is guaranteed thattrigger is always valid between request_irq() and free_irq(), butthe loopback testing mechanisms to invoke the handler functionneed to test the trigger. The triggering and setting ioctl pathsboth make use of igate and are therefore mutually exclusive.The vfio-fsl-mc driver does not make use of irqfds, nor does itsupport any sort of masking operations, therefore unlike vfio-pciand vfio-platform, the flow can remain essentially unchanged.

Description: In the Linux kernel, the following vulnerability has been resolved:eth: sungem: remove .ndo_poll_controller to avoid deadlocksErhard reports netpoll warnings from sungem: netpoll_send_skb_on_dev(): eth0 enabled interrupts in poll (gem_start_xmit+0x0/0x398) WARNING: CPU: 1 PID: 1 at net/core/netpoll.c:370 netpoll_send_skb+0x1fc/0x20cgem_poll_controller() disables interrupts, which may sleep.We can't sleep in netpoll, it has interrupts disabled completely.Strangely, gem_poll_controller() doesn't even poll the completions,and instead acts as if an interrupt has fired so it just schedulesNAPI and exits. None of this has been necessary for years, sincenetpoll invokes NAPI directly.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: fix racy may inline data check in dio writesyzbot reports that the following warning from ext4_iomap_begin()triggers as of the commit referenced below: if (WARN_ON_ONCE(ext4_has_inline_data(inode))) return -ERANGE;This occurs during a dio write, which is never expected to encounteran inode with inline data. To enforce this behavior,ext4_dio_write_iter() checks the current inline state of the inodeand clears the MAY_INLINE_DATA state flag to either fall back tobuffered writes, or enforce that any other writers in progress onthe inode are not allowed to create inline data.The problem is that the check for existing inline data and the stateflag can span a lock cycle. For example, if the ilock is originallylocked shared and subsequently upgraded to exclusive, another writermay have reacquired the lock and created inline data before the diowrite task acquires the lock and proceeds.The commit referenced below loosens the lock requirements to allowsome forms of unaligned dio writes to occur under shared lock, butAFAICT the inline data check was technically already racy for anydio write that would have involved a lock cycle. Regardless, liftclearing of the state bit to the same lock critical section thatchecks for preexisting inline data on the inode to close the race.

CVE-2025-38047 Severity: Moderate CVSS3 score: 3.4

Description: In the Linux kernel, the following vulnerability has been resolved:x86/fred: Fix system hang during S4 resume with FRED enabledUpon a wakeup from S4, the restore kernel starts and initializes theFRED MSRs as needed from its perspective. It then loads a hibernationimage, including the image kernel, and attempts to load image pagesdirectly into their original page frames used before hibernation unlessthose frames are currently in use. Once all pages are moved to theiroriginal locations, it jumps to a "trampoline" page in the image kernel.At this point, the image kernel takes control, but the FRED MSRs stillcontain values set by the restore kernel, which may differ from thoseset by the image kernel before hibernation. Therefore, the image kernelmust ensure the FRED MSRs have the same values as before hibernation.Since these values depend only on the location of the kernel text anddata, they can be recomputed from scratch.

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

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.

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

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

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

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