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

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

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

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

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

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

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

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

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

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

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

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

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

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

CVE-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-2025-69227 Severity: Important CVSS3 score: 7.5

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. This issue is fixed in version 3.13.3.

CVE-2025-69228 Severity: Important CVSS3 score: 7.5

Description: AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below allow a request to be crafted in such a way that an AIOHTTP server's memory fills up uncontrollably during processing. If an application includes a handler that uses the Request.post() method, an attacker may be able to freeze the server by exhausting the memory. This issue is fixed in version 3.13.3.

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.

CVE-2025-38685 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:fbdev: Fix vmalloc out-of-bounds write in fast_imageblitThis issue triggers when a userspace program does an ioctlFBIOPUT_CON2FBMAP by passing console number and frame buffer number.Ideally this maps console to frame buffer and updates the screen ifconsole is visible.As part of mapping it has to do resize of console according to framebuffer info. if this resize fails and returns from vc_do_resize() andcontinues further. At this point console and new frame buffer are mappedand sets display vars. Despite failure still it continue to proceedupdating the screen at later stages where vc_data is related to previousframe buffer and frame buffer info and display vars are mapped to newframe buffer and eventully leading to out-of-bounds write infast_imageblit(). This bheviour is excepted only when fg_console isequal to requested console which is a visible console and updates screenwith invalid struct references in fbcon_putcs().

CVE-2025-39750 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: ath12k: Correct tid cleanup when tid setup failsCurrently, if any error occurs during ath12k_dp_rx_peer_tid_setup(),the tid value is already incremented, even though the correspondingTID is not actually allocated. Proceed toath12k_dp_rx_peer_tid_delete() starting from unallocated tid,which might leads to freeing unallocated TID and cause potentialcrash or out-of-bounds access.Hence, fix by correctly decrementing tid before cleanup to match onlythe successfully allocated TIDs.Also, remove tid-- from failure case of ath12k_dp_rx_peer_frag_setup(),as decrementing the tid before cleanup in loop will take care of this.Compile tested only.

CVE-2025-39826 Severity: Important CVSS3 score: 7.0

Description: In the Linux kernel, the following vulnerability has been resolved:net: rose: convert 'use' field to refcount_tThe 'use' field in struct rose_neigh is used as a reference counter butlacks atomicity. This can lead to race conditions where a rose_neighstructure is freed while still being referenced by other code paths.For example, when rose_neigh->use becomes zero during an ioctl operationvia rose_rt_ioctl(), the structure may be removed while its timer isstill active, potentially causing use-after-free issues.This patch changes the type of 'use' from unsigned short to refcount_t andupdates all code paths to use rose_neigh_hold() and rose_neigh_put() whichoperate reference counts atomically.

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

CVE-2025-64505 Severity: Moderate CVSS3 score: 6.8

Description: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Prior to version 1.6.51, a heap buffer over-read vulnerability exists in libpng's png_do_quantize function when processing PNG files with malformed palette indices. The vulnerability occurs when palette_lookup array bounds are not validated against externally-supplied image data, allowing an attacker to craft a PNG file with out-of-range palette indices that trigger out-of-bounds memory access. This issue has been patched in version 1.6.51.

Description: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. From version 1.6.0 to before 1.6.51, a heap buffer over-read vulnerability exists in libpng's png_write_image_8bit function when processing 8-bit images through the simplified write API with convert_to_8bit enabled. The vulnerability affects 8-bit grayscale+alpha, RGB/RGBA, and images with incomplete row data. A conditional guard incorrectly allows 8-bit input to enter code expecting 16-bit input, causing reads up to 2 bytes beyond allocated buffer boundaries. This issue has been patched in version 1.6.51.

CVE-2023-53311 Severity: Moderate CVSS3 score: 6.7

Description: In the Linux kernel, the following vulnerability has been resolved:nilfs2: fix use-after-free of nilfs_root in dirtying inodes via iputDuring unmount process of nilfs2, nothing holds nilfs_root structure afternilfs2 detaches its writer in nilfs_detach_log_writer(). Previously,nilfs_evict_inode() could cause use-after-free read for nilfs_root ifinodes are left in "garbage_list" and released by nilfs_dispose_list atthe end of nilfs_detach_log_writer(), and this bug was fixed by commit9b5a04ac3ad9 ("nilfs2: fix use-after-free bug of nilfs_root innilfs_evict_inode()").However, it turned out that there is another possibility of UAF in thecall path where mark_inode_dirty_sync() is called from iput():nilfs_detach_log_writer() nilfs_dispose_list() iput() mark_inode_dirty_sync() __mark_inode_dirty() nilfs_dirty_inode() __nilfs_mark_inode_dirty() nilfs_load_inode_block() --> causes UAF of nilfs_root structThis can happen after commit 0ae45f63d4ef ("vfs: add support for alazytime mount option"), which changed iput() to callmark_inode_dirty_sync() on its final reference if i_state has I_DIRTY_TIMEflag and i_nlink is non-zero.This issue appears after commit 28a65b49eb53 ("nilfs2: do not write dirtydata after degenerating to read-only") when using the syzbot reproducer,but the issue has potentially existed before.Fix this issue by adding a "purging flag" to the nilfs structure, settingthat flag while disposing the "garbage_list" and checking it in__nilfs_mark_inode_dirty().Unlike commit 9b5a04ac3ad9 ("nilfs2: fix use-after-free bug of nilfs_rootin nilfs_evict_inode()"), this patch does not rely on ns_writer todetermine whether to skip operations, so as not to break recovery onmount. The nilfs_salvage_orphan_logs routine dirties the buffer ofsalvaged data before attaching the log writer, so changing__nilfs_mark_inode_dirty() to skip the operation when ns_writer is NULLwill cause recovery write to fail. The purpose of using the cleanup-onlyflag is to allow for narrowing of such conditions.

Description: In the Linux kernel, the following vulnerability has been resolved:lwt: Fix return values of BPF xmit opsBPF encap ops can return different types of positive values, such likeNET_RX_DROP, NET_XMIT_CN, NETDEV_TX_BUSY, and so on, from functionskb_do_redirect and bpf_lwt_xmit_reroute. At the xmit hook, such returnvalues would be treated implicitly as LWTUNNEL_XMIT_CONTINUE inip(6)_finish_output2. When this happens, skbs that have been freed wouldcontinue to the neighbor subsystem, causing use-after-free bug andkernel crashes.To fix the incorrect behavior, skb_do_redirect return values can besimply discarded, the same as tc-egress behavior. On the other hand,bpf_lwt_xmit_reroute returns useful errors to local senders, e.g. PMTUinformation. Thus convert its return values to avoid the conflict withLWTUNNEL_XMIT_CONTINUE.

CVE-2023-53515 Severity: Moderate CVSS3 score: 6.7

Description: In the Linux kernel, the following vulnerability has been resolved:virtio-mmio: don't break lifecycle of vm_devvm_dev has a separate lifecycle because it has a 'struct device'embedded. Thus, having a release callback for it is correct.Allocating the vm_dev struct with devres totally breaks this protection,though. Instead of waiting for the vm_dev release callback, the memoryis freed when the platform_device is removed. Resulting in ause-after-free when finally the callback is to be called.To easily see the problem, compile the kernel withCONFIG_DEBUG_KOBJECT_RELEASE and unbind with sysfs.The fix is easy, don't use devres in this case.Found during my research about object lifetime problems.

CVE-2023-53619 Severity: Moderate CVSS3 score: 6.7

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: conntrack: Avoid nf_ct_helper_hash uses after freeIf nf_conntrack_init_start() fails (for example due to aregister_nf_conntrack_bpf() failure), the nf_conntrack_helper_fini()clean-up path frees the nf_ct_helper_hash map.When built with NF_CONNTRACK=y, further netfilter modules (e.g:netfilter_conntrack_ftp) can still be loaded and callnf_conntrack_helpers_register(), independently of whether nf_conntrackinitialized correctly. This accesses the nf_ct_helper_hash danglingpointer and causes a uaf, possibly leading to random memory corruption.This patch guards nf_conntrack_helper_register() from accessing a freedor uninitialized nf_ct_helper_hash pointer and fixes possibleuses-after-free when loading a conntrack module.

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.

However, the routinesthat save and restore the state miss a significnt part of thevariable state in the wqe, the dma struct which is used to processthrough the sge table. And, the state is not saved before the packetis built which modifies the dma struct.Under heavy stress testing with many QPs on a fast node sendinglarge messages to a slow node dropped packets are observed andthe resent packets are corrupted because the dma struct was notrestored. This patch fixes this behavior and allows the test casesto succeed.

CVE-2025-39759 Severity: Moderate CVSS3 score: 6.4

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

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

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

CVE-2025-40043 Severity: Moderate CVSS3 score: 6.3

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:Squashfs: fix uninit-value in squashfs_get_parentSyzkaller reports a "KMSAN: uninit-value in squashfs_get_parent" bug.This is caused by open_by_handle_at() being called with a file handlecontaining an invalid parent inode number. In particular the inode numberis that of a symbolic link, rather than a directory.Squashfs_get_parent() gets called with that symbolic link inode, andaccesses the parent member field. unsigned int parent_ino = squashfs_i(inode)->parent;Because non-directory inodes in Squashfs do not have a parent value, thisis uninitialised, and this causes an uninitialised value access.The fix is to initialise parent with the invalid inode 0, which will causean EINVAL error to be returned.Regular inodes used to share the parent field with the block_list_startfield. This is removed in this commit to enable the parent field tocontain the invalid inode number 0.

One of theports has an expander connected. The expander has 31 phys with phy ids0-30.The pm8001_ha->phy array only contains the phys of the HBA. It does notcontain the phys of the expander. Thus, it is wrong to use attached_phyto index the pm8001_ha->phy array for a device behind an expander.Thus, we can only clear phy_attached for devices that are directlyattached.

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

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

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

CVE-2023-53438 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:x86/MCE: Always save CS register on AMD Zen IF Poison errorsThe Instruction Fetch (IF) units on current AMD Zen-based systems do notguarantee a synchronous #MC is delivered for poison consumption errors.Therefore, MCG_STATUS[EIPV|RIPV] will not be set. However, themicroarchitecture does guarantee that the exception is delivered withinthe same context. In other words, the exact rIP is not known, but thecontext is known to not have changed.There is no architecturally-defined method to determine this behavior.The Code Segment (CS) register is always valid on such IF unit poisonerrors regardless of the value of MCG_STATUS[EIPV|RIPV].Add a quirk to save the CS register for poison consumption from the IFunit banks.This is needed to properly determine the context of the error.Otherwise, the severity grading function will assume the context isIN_KERNEL due to the m->cs value being 0 (the initialized value). Thisleads to unnecessary kernel panics on data poison errors due to thekernel believing the poison consumption occurred in kernel context.

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

CVE-2025-40096 Severity: Moderate CVSS3 score: 5.8

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

CVE-2025-40169 Severity: Moderate CVSS3 score: 5.8

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

CVE-2023-53184 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:arm64/sme: Set new vector length before reallocatingAs part of fixing the allocation of the buffer for SVE state when changingSME vector length we introduced an immediate reallocation of the SVE state,this is also done when changing the SVE vector length for consistency.Unfortunately this reallocation is done prior to writing the new vectorlength to the task struct, meaning the allocation is done with the oldvector length and can lead to memory corruption due to an undersized bufferbeing used.Move the update of the vector length before the allocation to ensure thatthe new vector length is taken into account.For some reason this isn't triggering any problems when running tests onthe arm64 fixes branch (even after repeated tries) but is triggeringissues very often after merge into mainline.

CVE-2023-53187 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix use-after-free of new block group that became unusedIf a task creates a new block group and that block group becomes unusedbefore we finish its creation, at btrfs_create_pending_block_groups(),then when btrfs_mark_bg_unused() is called against the block group, weassume that the block group is currently in the list of block groups toreclaim, and we move it out of the list of new block groups and into thelist of unused block groups. This has two consequences:1) We move it out of the list of new block groups associated to the current transaction. So the block group creation is not finished and if we attempt to delete the bg because it's unused, we will not find the block group item in the extent tree (or the new block group tree), its device extent items in the device tree etc, resulting in the deletion to fail due to the missing items;2) We don't increment the reference count on the block group when we move it to the list of unused block groups, because we assumed the block group was on the list of block groups to reclaim, and in that case it already has the correct reference count. However the block group was on the list of new block groups, in which case no extra reference was taken because it's local to the current task. This later results in doing an extra reference count decrement when removing the block group from the unused list, eventually leading the reference count to 0.This second case was caught when running generic/297 from fstests, whichproduced the following assertion failure and stack trace: [589.559] assertion failed: refcount_read(&block_group->refs) == 1, in fs/btrfs/block-group.c:4299 [589.559] ------------[ cut here ]------------ [589.559] kernel BUG at fs/btrfs/block-group.c:4299!

In the caseof resilient nexthop groups, nexthop_select_path_res() may do an out ofbounds access in nh_buckets[], for example: hash = -912054133 num_nh_buckets = 2 bucket_index = 65535which leads to the following panic:BUG: unable to handle page fault for address: ffffc900025910c8PGD 100000067 P4D 100000067 PUD 10026b067 PMD 0Oops: 0002 [#1] PREEMPT SMP KASAN NOPTICPU: 4 PID: 856 Comm: kworker/4:3 Not tainted 6.5.0-rc2+ #34Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.2-debian-1.16.2-1 04/01/2014Workqueue: ipv6_addrconf addrconf_dad_workRIP: 0010:nexthop_select_path+0x197/0xbf0Code: c1 e4 05 be 08 00 00 00 4c 8b 35 a4 14 7e 01 4e 8d 6c 25 00 4a 8d 7c 25 08 48 01 dd e8 c2 25 15 ff 49 8d 7d 08 e8 39 13 15 ff <4d> 89 75 08 48 89 ef e8 7d 12 15 ff 48 8b 5d 00 e8 14 55 2f 00 85RSP: 0018:ffff88810c36f260 EFLAGS: 00010246RAX: 0000000000000000 RBX: 00000000002000c0 RCX: ffffffffaf02dd77RDX: dffffc0000000000 RSI: 0000000000000008 RDI: ffffc900025910c8RBP: ffffc900025910c0 R08: 0000000000000001 R09: fffff520004b2219R10: ffffc900025910cf R11: 31392d2068736168 R12: 00000000002000c0R13: ffffc900025910c0 R14: 00000000fffef608 R15: ffff88811840e900FS: 0000000000000000(0000) GS:ffff8881f7000000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: ffffc900025910c8 CR3: 0000000129d00000 CR4: 0000000000750ee0PKRU: 55555554Call Trace: ? __die+0x23/0x70 ? page_fault_oops+0x1ee/0x5c0 ? __pfx_is_prefetch.constprop.0+0x10/0x10 ? __pfx_page_fault_oops+0x10/0x10 ? search_bpf_extables+0xfe/0x1c0 ? fixup_exception+0x3b/0x470 ? exc_page_fault+0xf6/0x110 ? asm_exc_page_fault+0x26/0x30 ? nexthop_select_path+0x197/0xbf0 ? nexthop_select_path+0x197/0xbf0 ? lock_is_held_type+0xe7/0x140 vxlan_xmit+0x5b2/0x2340 ? __lock_acquire+0x92b/0x3370 ? __pfx_vxlan_xmit+0x10/0x10 ? __pfx___lock_acquire+0x10/0x10 ? __pfx_register_lock_class+0x10/0x10 ? skb_network_protocol+0xce/0x2d0 ? dev_hard_start_xmit+0xca/0x350 ? __pfx_vxlan_xmit+0x10/0x10 dev_hard_start_xmit+0xca/0x350 __dev_queue_xmit+0x513/0x1e20 ? __pfx___dev_queue_xmit+0x10/0x10 ? __pfx_lock_release+0x10/0x10 ? mark_held_locks+0x44/0x90 ? skb_push+0x4c/0x80 ? eth_header+0x81/0xe0 ? __pfx_eth_header+0x10/0x10 ? neigh_resolve_output+0x215/0x310 ? ip6_finish_output2+0x2ba/0xc90 ip6_finish_output2+0x2ba/0xc90 ? lock_release+0x236/0x3e0 ? ip6_mtu+0xbb/0x240 ? __pfx_ip6_finish_output2+0x10/0x10 ? find_held_lock+0x83/0xa0 ? lock_is_held_type+0xe7/0x140 ip6_finish_output+0x1ee/0x780 ip6_output+0x138/0x460 ? __pfx_ip6_output+0x10/0x10 ? __pfx___lock_acquire+0x10/0x10 ? __pfx_ip6_finish_output+0x10/0x10 NF_HOOK.constprop.0+0xc0/0x420 ? __pfx_NF_HOOK.constprop.0+0x10/0x10 ? ndisc_send_skb+0x2c0/0x960 ? __pfx_lock_release+0x10/0x10 ? __local_bh_enable_ip+0x93/0x110 ? lock_is_held_type+0xe7/0x140 ndisc_send_skb+0x4be/0x960 ? __pfx_ndisc_send_skb+0x10/0x10 ? mark_held_locks+0x65/0x90 ? find_held_lock+0x83/0xa0 ndisc_send_ns+0xb0/0x110 ? __pfx_ndisc_send_ns+0x10/0x10 addrconf_dad_work+0x631/0x8e0 ? lock_acquire+0x180/0x3f0 ? __pfx_addrconf_dad_work+0x10/0x10 ? mark_held_locks+0x24/0x90 process_one_work+0x582/0x9c0 ? __pfx_process_one_work+0x10/0x10 ? __pfx_do_raw_spin_lock+0x10/0x10 ? mark_held_locks+0x24/0x90 worker_thread+0x93/0x630 ? __kthread_parkme+0xdc/0x100 ? __pfx_worker_thread+0x10/0x10 kthread+0x1a5/0x1e0 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x34/0x60 ---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/bnxt_re: wraparound mbox producer indexDriver is not handling the wraparound of the mbox producer index correctly.Currently the wraparound happens once u32 max is reached.Bit 31 of the producer index register is special and should be setonly once for the first command. Because the producer index overflowsetting bit31 after a long time, FW goes to initialization sequenceand this causes FW hang.Fix is to wraparound the mbox producer index once it reaches u16 max.

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: nSVM: Load L1's TSC multiplier based on L1 state, not L2 stateWhen emulating nested VM-Exit, load L1's TSC multiplier if L1's desiredratio doesn't match the current ratio, not if the ratio L1 is using forL2 diverges from the default. Functionally, the end result is the sameas KVM will run L2 with L1's multiplier if L2's multiplier is the default,i.e. checking that L1's multiplier is loaded is equivalent to checking ifL2 has a non-default multiplier.However, the assertion that TSC scaling is exposed to L1 is flawed, asuserspace can trigger the WARN at will by writing the MSR and thenupdating guest CPUID to hide the feature (modifying guest CPUID isallowed anytime before KVM_RUN). E.g. hacking KVM's state_testselftest to do vcpu_set_msr(vcpu, MSR_AMD64_TSC_RATIO, 0); vcpu_clear_cpuid_feature(vcpu, X86_FEATURE_TSCRATEMSR);after restoring state in a new VM+vCPU yields an endless supply of: ------------[ cut here ]------------ WARNING: CPU: 10 PID: 206939 at arch/x86/kvm/svm/nested.c:1105 nested_svm_vmexit+0x6af/0x720 [kvm_amd] Call Trace: nested_svm_exit_handled+0x102/0x1f0 [kvm_amd] svm_handle_exit+0xb9/0x180 [kvm_amd] kvm_arch_vcpu_ioctl_run+0x1eab/0x2570 [kvm] kvm_vcpu_ioctl+0x4c9/0x5b0 [kvm] ? trace_hardirqs_off+0x4d/0xa0 __se_sys_ioctl+0x7a/0xc0 __x64_sys_ioctl+0x21/0x30 do_syscall_64+0x41/0x90 entry_SYSCALL_64_after_hwframe+0x63/0xcdUnlike the nested VMRUN path, hoisting the svm->tsc_scaling_enabled checkinto the if-statement is wrong as KVM needs to ensure L1's multiplier isloaded in the above scenario. Alternatively, the WARN_ON() could simplybe deleted, but that would make KVM's behavior even more subtle, e.g. it'snot immediately obvious why it's safe to write MSR_AMD64_TSC_RATIO whenchecking only tsc_ratio_msr.

CVE-2023-53231 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:erofs: Fix detection of atomic contextCurrent check for atomic context is not sufficient asz_erofs_decompressqueue_endio can be called under rcu lockfrom blk_mq_flush_plug_list(). See the stacktrace [1]In such case we should hand off the decompression work for asyncprocessing rather than trying to do sync decompression in currentcontext. Patch fixes the detection by checking forrcu_read_lock_any_held() and while at it use more appropriate!in_task() check than in_atomic().Background: Historically erofs would always schedule a kworker fordecompression which would incur the scheduling cost regardless ofthe context. But z_erofs_decompressqueue_endio() may not alwaysbe in atomic context and we could actually benefit from doing thedecompression in z_erofs_decompressqueue_endio() if we are inthread context, for example when running with dm-verity.This optimization was later added in patch [2] which has shownimprovement in performance benchmarks.==============================================[1] Problem stacktrace[name:core&]BUG: sleeping function called from invalid context at kernel/locking/mutex.c:291[name:core&]in_atomic(): 0, irqs_disabled(): 0, non_block: 0, pid: 1615, name: CpuMonitorServi[name:core&]preempt_count: 0, expected: 0[name:core&]RCU nest depth: 1, expected: 0CPU: 7 PID: 1615 Comm: CpuMonitorServi Tainted: G S W OE 6.1.25-android14-5-maybe-dirty-mainline #1Hardware name: MT6897 (DT)Call trace: dump_backtrace+0x108/0x15c show_stack+0x20/0x30 dump_stack_lvl+0x6c/0x8c dump_stack+0x20/0x48 __might_resched+0x1fc/0x308 __might_sleep+0x50/0x88 mutex_lock+0x2c/0x110 z_erofs_decompress_queue+0x11c/0xc10 z_erofs_decompress_kickoff+0x110/0x1a4 z_erofs_decompressqueue_endio+0x154/0x180 bio_endio+0x1b0/0x1d8 __dm_io_complete+0x22c/0x280 clone_endio+0xe4/0x280 bio_endio+0x1b0/0x1d8 blk_update_request+0x138/0x3a4 blk_mq_plug_issue_direct+0xd4/0x19c blk_mq_flush_plug_list+0x2b0/0x354 __blk_flush_plug+0x110/0x160 blk_finish_plug+0x30/0x4c read_pages+0x2fc/0x370 page_cache_ra_unbounded+0xa4/0x23c page_cache_ra_order+0x290/0x320 do_sync_mmap_readahead+0x108/0x2c0 filemap_fault+0x19c/0x52c __do_fault+0xc4/0x114 handle_mm_fault+0x5b4/0x1168 do_page_fault+0x338/0x4b4 do_translation_fault+0x40/0x60 do_mem_abort+0x60/0xc8 el0_da+0x4c/0xe0 el0t_64_sync_handler+0xd4/0xfc el0t_64_sync+0x1a0/0x1a4[2] Link: https://lore.kernel.org/all/20210317035448.13921-1-huangjianan@oppo.com/

CVE-2023-53245 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: storvsc: Fix handling of virtual Fibre Channel timeoutsHyper-V provides the ability to connect Fibre Channel LUNs to the hostsystem and present them in a guest VM as a SCSI device. I/O to the vFCdevice is handled by the storvsc driver. The storvsc driver includes apartial integration with the FC transport implemented in the genericportion of the Linux SCSI subsystem so that FC attributes can be displayedin /sys. However, the partial integration means that some aspects of vFCdon't work properly. Unfortunately, a full and correct integration isn'tpractical because of limitations in what Hyper-V provides to the guest.In particular, in the context of Hyper-V storvsc, the FC transport timeoutfunction fc_eh_timed_out() causes a kernel panic because it can't find therport and dereferences a NULL pointer. The original patch that added thecall from storvsc_eh_timed_out() to fc_eh_timed_out() is faulty in thisregard.In many cases a timeout is due to a transient condition, so the situationcan be improved by just continuing to wait like with other I/O requestsissued by storvsc, and avoiding the guaranteed panic. For a permanentfailure, continuing to wait may result in a hung thread instead of a panic,which again may be better.So fix the panic by removing the storvsc call to fc_eh_timed_out(). Thisallows storvsc to keep waiting for a response. The change has been testedby users who experienced a panic in fc_eh_timed_out() due to transienttimeouts, and it solves their problem.In the future we may want to deprecate the vFC functionality in storvscsince it can't be fully fixed. But it has current users for whom it isworking well enough, so it should probably stay for a while longer.

However between theread and re-locking the page we could have called release_folio() on thepage, but left the page in the file mapping. release_folio() can clearthe page private, and thus further down we blow up when we go to modifythe subpage bits.Fix this by putting the set_page_extent_mapped() after the read. Thisis safe because read_folio() will call set_page_extent_mapped() beforeit does the read, and then if we clear page private but leave it on themapping we're completely safe re-setting set_page_extent_mapped(). Withthis patch I can now run generic/476 without panicing.

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/mlx5: Return the firmware result upon destroying QP/RQPreviously when destroying a QP/RQ, the result of the firmwaredestruction function was ignored and upper layers weren't informedabout the failure.Which in turn could lead to various problems since when upper layerisn't aware of the failure it continues its operation thinking that therelated QP/RQ was successfully destroyed while it actually wasn't,which could lead to the below kernel WARN.Currently, we return the correct firmware destruction status to upperlayers which in case of the RQ would be mlx5_ib_destroy_wq() whichwas already capable of handling RQ destruction failure or in case ofa QP to destroy_qp_common(), which now would actually warn upon qpdestruction failure.WARNING: CPU: 3 PID: 995 at drivers/infiniband/core/rdma_core.c:940 uverbs_destroy_ufile_hw+0xcb/0xe0 [ib_uverbs]Modules linked in: xt_conntrack xt_MASQUERADE nf_conntrack_netlink nfnetlink xt_addrtype iptable_nat nf_nat br_netfilter rpcrdma rdma_ucm ib_iser libiscsi scsi_transport_iscsi rdma_cm ib_umad ib_ipoib iw_cm ib_cm mlx5_ib ib_uverbs ib_core overlay mlx5_core fuseCPU: 3 PID: 995 Comm: python3 Not tainted 5.16.0-rc5+ #1Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014RIP: 0010:uverbs_destroy_ufile_hw+0xcb/0xe0 [ib_uverbs]Code: 41 5c 41 5d 41 5e e9 44 34 f0 e0 48 89 df e8 4c 77 ff ff 49 8b 86 10 01 00 00 48 85 c0 74 a1 4c 89 e7 ff d0 eb 9a 0f 0b eb c1 <0f> 0b be 04 00 00 00 48 89 df e8 b6 f6 ff ff e9 75 ff ff ff 90 0fRSP: 0018:ffff8881533e3e78 EFLAGS: 00010287RAX: ffff88811b2cf3e0 RBX: ffff888106209700 RCX: 0000000000000000RDX: ffff888106209780 RSI: ffff8881533e3d30 RDI: ffff888109b101a0RBP: 0000000000000001 R08: ffff888127cb381c R09: 0de9890000000009R10: ffff888127cb3800 R11: 0000000000000000 R12: ffff888106209780R13: ffff888106209750 R14: ffff888100f20660 R15: 0000000000000000FS: 00007f8be353b740(0000) GS:ffff88852c980000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007f8bd5b117c0 CR3: 000000012cd8a004 CR4: 0000000000370ea0DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400Call Trace: ib_uverbs_close+0x1a/0x90 [ib_uverbs] __fput+0x82/0x230 task_work_run+0x59/0x90 exit_to_user_mode_prepare+0x138/0x140 syscall_exit_to_user_mode+0x1d/0x50 ? __x64_sys_close+0xe/0x40 do_syscall_64+0x4a/0x90 entry_SYSCALL_64_after_hwframe+0x44/0xaeRIP: 0033:0x7f8be3ae0abbCode: 03 00 00 00 0f 05 48 3d 00 f0 ff ff 77 41 c3 48 83 ec 18 89 7c 24 0c e8 83 43 f9 ff 8b 7c 24 0c 41 89 c0 b8 03 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 35 44 89 c7 89 44 24 0c e8 c1 43 f9 ff 8b 44RSP: 002b:00007ffdb51909c0 EFLAGS: 00000293 ORIG_RAX: 0000000000000003RAX: 0000000000000000 RBX: 0000557bb7f7c020 RCX: 00007f8be3ae0abbRDX: 0000557bb7c74010 RSI: 0000557bb7f14ca0 RDI: 0000000000000005RBP: 0000557bb7fbd598 R08: 0000000000000000 R09: 0000000000000000R10: 0000000000000000 R11: 0000000000000293 R12: 0000557bb7fbd5b8R13: 0000557bb7fbd5a8 R14: 0000000000001000 R15: 0000557bb7f7c020

CVE-2023-53323 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ext2/dax: Fix ext2_setsize when len is page alignedPAGE_ALIGN(x) macro gives the next highest value which is multiple ofpagesize. But if x is already page aligned then it simply returns x.So, if x passed is 0 in dax_zero_range() function, that means thelength gets passed as 0 to ->iomap_begin().In ext2 it then calls ext2_get_blocks -> max_blocks as 0 and hits bug_onhere in ext2_get_blocks(). BUG_ON(maxblocks == 0);Instead we should be calling dax_truncate_page() here which takescare of it. i.e. it only calls dax_zero_range if the offset is notpage/block aligned.This can be easily triggered with following on fsdax mounted pmemdevice.dd if=/dev/zero of=file count=1 bs=512truncate -s 0 file[79.525838] EXT2-fs (pmem0): DAX enabled.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: conntrack: dccp: copy entire header to stack buffer, not just basic oneEric Dumazet says: nf_conntrack_dccp_packet() has an unique: dh = skb_header_pointer(skb, dataoff, sizeof(_dh), &_dh); And nothing more is 'pulled' from the packet, depending on the content. dh->dccph_doff, and/or dh->dccph_x ...) So dccp_ack_seq() is happily reading stuff past the _dh buffer.BUG: KASAN: stack-out-of-bounds in nf_conntrack_dccp_packet+0x1134/0x11c0Read of size 4 at addr ffff000128f66e0c by task syz-executor.2/29371[..]Fix this by increasing the stack buffer to also include room forthe extra sequence numbers and all the known dccp packet type headers,then pull again after the initial validation of the basic header.While at it, mark packets invalid that lack 48bit sequence bit butwhere RFC says the type MUST use them.Compile tested only.v2: first skb_header_pointer() now needs to adjust the size to only pull the generic header.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: u_serial: Add null pointer check in gserial_suspendConsider a case where gserial_disconnect has already clearedgser->ioport. And if gserial_suspend gets called afterwards,it will lead to accessing of gser->ioport and thus causingnull pointer dereference.Avoid this by adding a null pointer check. Added a staticspinlock to prevent gser->ioport from becoming null afterthe newly added null pointer check.

Description: In the Linux kernel, the following vulnerability has been resolved:NFSv4.2: Rework scratch handling for READ_PLUS (again)I found that the read code might send multiple requests using the samenfs_pgio_header, but nfs4_proc_read_setup() is only called once. This ishow we ended up occasionally double-freeing the scratch buffer, but alsomeans we set a NULL pointer but non-zero length to the xdr scratchbuffer. This results in an oops the first time decoding needs to copysomething to scratch, which frequently happens when decoding READ_PLUShole segments.I fix this by moving scratch handling into the pageio read code. Iprovide a function to allocate scratch space for decoding read replies,and free the scratch buffer when the nfs_pgio_header is freed.

Description: In the Linux kernel, the following vulnerability has been resolved:regulator: da9063: better fix null deref with partial DTTwo versions of the original patch were sent but V1 was merged insteadof V2 due to a mistake.So update to V2.The advantage of V2 is that it completely avoids dereferencing the pointer,even just to take the address, which may fix problems with some compilers.Both versions work on my gcc 9.4 but use the safer one.

Description: In the Linux kernel, the following vulnerability has been resolved:net: dcb: choose correct policy to parse DCB_ATTR_BCNThe dcbnl_bcn_setcfg uses erroneous policy to parse tb[DCB_ATTR_BCN],which is introduced in commit 859ee3c43812 ("DCB: Add support for DCBBCN"). Please see the comment in below codestatic int dcbnl_bcn_setcfg(...){ ... ret = nla_parse_nested_deprecated(..., dcbnl_pfc_up_nest, .. ) // !!! dcbnl_pfc_up_nest for attributes // DCB_PFC_UP_ATTR_0 to DCB_PFC_UP_ATTR_ALL in enum dcbnl_pfc_up_attrs ... for (i = DCB_BCN_ATTR_RP_0; i <= DCB_BCN_ATTR_RP_7; i++) { // !!!

DCB_BCN_ATTR_BCNA_0 to DCB_BCN_ATTR_RI in enum dcbnl_bcn_attrs ... value_int = nla_get_u32(data[i]); ... } ...}That is, the nla_parse_nested_deprecated uses dcbnl_pfc_up_nestattributes to parse nlattr defined in dcbnl_pfc_up_attrs. But thefollowing access code fetch each nlattr as dcbnl_bcn_attrs attributes.By looking up the associated nla_policy for dcbnl_bcn_attrs. We can findthe beginning part of these two policies are "same".static const struct nla_policy dcbnl_pfc_up_nest[...] = { [DCB_PFC_UP_ATTR_0] = {.type = NLA_U8}, [DCB_PFC_UP_ATTR_1] = {.type = NLA_U8}, [DCB_PFC_UP_ATTR_2] = {.type = NLA_U8}, [DCB_PFC_UP_ATTR_3] = {.type = NLA_U8}, [DCB_PFC_UP_ATTR_4] = {.type = NLA_U8}, [DCB_PFC_UP_ATTR_5] = {.type = NLA_U8}, [DCB_PFC_UP_ATTR_6] = {.type = NLA_U8}, [DCB_PFC_UP_ATTR_7] = {.type = NLA_U8}, [DCB_PFC_UP_ATTR_ALL] = {.type = NLA_FLAG},};static const struct nla_policy dcbnl_bcn_nest[...] = { [DCB_BCN_ATTR_RP_0] = {.type = NLA_U8}, [DCB_BCN_ATTR_RP_1] = {.type = NLA_U8}, [DCB_BCN_ATTR_RP_2] = {.type = NLA_U8}, [DCB_BCN_ATTR_RP_3] = {.type = NLA_U8}, [DCB_BCN_ATTR_RP_4] = {.type = NLA_U8}, [DCB_BCN_ATTR_RP_5] = {.type = NLA_U8}, [DCB_BCN_ATTR_RP_6] = {.type = NLA_U8}, [DCB_BCN_ATTR_RP_7] = {.type = NLA_U8}, [DCB_BCN_ATTR_RP_ALL] = {.type = NLA_FLAG}, // from here is somewhat different [DCB_BCN_ATTR_BCNA_0] = {.type = NLA_U32}, ... [DCB_BCN_ATTR_ALL] = {.type = NLA_FLAG},};Therefore, the current code is buggy and thisnla_parse_nested_deprecated could overflow the dcbnl_pfc_up_nest and usethe adjacent nla_policy to parse attributes from DCB_BCN_ATTR_BCNA_0.Hence use the correct policy dcbnl_bcn_nest to parse the nestedtb[DCB_ATTR_BCN] TLV.

Description: In the Linux kernel, the following vulnerability has been resolved:blk-cgroup: Reinit blkg_iostat_set after clearing in blkcg_reset_stats()When blkg_alloc() is called to allocate a blkcg_gq structurewith the associated blkg_iostat_set's, there are 2 fields withinblkg_iostat_set that requires proper initialization - blkg & sync.The former field was introduced by commit 3b8cc6298724 ("blk-cgroup:Optimize blkcg_rstat_flush()") while the later one was introduced bycommit f73316482977 ("blk-cgroup: reimplement basic IO stats usingcgroup rstat").Unfortunately those fields in the blkg_iostat_set's are not properlyre-initialized when they are cleared in v1's blkcg_reset_stats(). Thiscan lead to a kernel panic due to NULL pointer access of the blkgpointer. The missing initialization of sync is less problematic andcan be a problem in a debug kernel due to missing lockdep initialization.Fix these problems by re-initializing them after memory clearing.

CVE-2023-53426 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:xsk: Fix xsk_diag use-after-free error during socket cleanupFix a use-after-free error that is possible if the xsk_diag interfaceis used after the socket has been unbound from the device. This canhappen either due to the socket being closed or the devicedisappearing. In the early days of AF_XDP, the way we tested that asocket was not bound to a device was to simply check if the netdevicepointer in the xsk socket structure was NULL. Later, a better systemwas introduced by having an explicit state variable in the xsk socketstruct. For example, the state of a socket that is on the way to beingclosed and has been unbound from the device is XSK_UNBOUND.The commit in the Fixes tag below deleted the old way of signallingthat a socket is unbound, setting dev to NULL. This in the belief thatall code using the old way had been exterminated. That wasunfortunately not true as the xsk diagnostics code was still using theold way and thus does not work as intended when a socket is goingdown. Fix this by introducing a test against the state variable. Ifthe socket is in the state XSK_UNBOUND, simply abort the diagnostic'snetlink operation.

CVE-2023-53428 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:powercap: arm_scmi: Remove recursion while parsing zonesPowercap zones can be defined as arranged in a hierarchy of trees and whenregistering a zone with powercap_register_zone(), the kernel powercapsubsystem expects this to happen starting from the root zones down to theleaves; on the other side, de-registration by powercap_deregister_zone()must begin from the leaf zones.Available SCMI powercap zones are retrieved dynamically from the platformat probe time and, while any defined hierarchy between the zones isdescribed properly in the zones descriptor, the platform returns theavailables zones with no particular well-defined order: as a consequence,the trees possibly composing the hierarchy of zones have to be somehowwalked properly to register the retrieved zones from the root.Currently the ARM SCMI Powercap driver walks the zones using a recursivealgorithm; this approach, even though correct and tested can lead to kernelstack overflow when processing a returned hierarchy of zones composed byparticularly high trees.Avoid possible kernel stack overflow by substituting the recursive approachwith an iterative one supported by a dynamically allocated stack-like datastructure.

CVE-2023-53429 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: don't check PageError in __extent_writepage__extent_writepage currenly sets PageError whenever any error happens,and the also checks for PageError to decide if to call error handling.This leads to very unclear responsibility for cleaning up on errors.In the VM and generic writeback helpers the basic idea is that onceI/O is fired off all error handling responsibility is delegated to theend I/O handler. But if that end I/O handler sets the PageError bit,and the submitter checks it, the bit could in some cases leak into thesubmission context for fast enough I/O.Fix this by simply not checking PageError and just using the localret variable to check for submission errors. This also fundamentallysolves the long problem documented in a comment in __extent_writepageby never leaking the error bit into the submission context.

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring: wait interruptibly for request completions on exitWHen the ring exits, cleanup is done and the final cancelation andwaiting on completions is done by io_ring_exit_work. That function isinvoked by kworker, which doesn't take any signals. Because of that, itdoesn't really matter if we wait for completions in TASK_INTERRUPTIBLEor TASK_UNINTERRUPTIBLE state. However, it does matter to the hung taskdetection checker!Normally we expect cancelations and completions to happen ratherquickly. Some test cases, however, will exit the ring and park theowning task stopped (eg via SIGSTOP). If the owning task needs to runtask_work to complete requests, then io_ring_exit_work won't make anyprogress until the task is runnable again. Hence io_ring_exit_work cantrigger the hung task detection, which is particularly problematic ifpanic-on-hung-task is enabled.As the ring exit doesn't take signals to begin with, have it waitinterruptibly rather than uninterruptibly. io_uring has a separatestuck-exit warning that triggers independently anyway, so we're notreally missing anything by making this switch.

CVE-2023-53463 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ibmvnic: Do not reset dql stats on NON_FATAL errAll ibmvnic resets, make a call to netdev_tx_reset_queue() whenre-opening the device. netdev_tx_reset_queue() resets the num_queuedand num_completed byte counters. These stats are used in Byte QueueLimit (BQL) algorithms. The difference between these two stats tracksthe number of bytes currently sitting on the physical NIC. ibmvnicincreases the number of queued bytes though calls tonetdev_tx_sent_queue() in the drivers xmit function. When, VIOS reportsthat it is done transmitting bytes, the ibmvnic device increases thenumber of completed bytes through calls to netdev_tx_completed_queue().It is important to note that the driver batches its transmit calls andnum_queued is increased every time that an skb is added to the nextbatch, not necessarily when the batch is sent to VIOS for transmission.Unlike other reset types, a NON FATAL reset will not flush the sub crqtx buffers. Therefore, it is possible for the batched skb array to bepartially full. So if there is call to netdev_tx_reset_queue() whenre-opening the device, the value of num_queued (0) would not accountfor the skb's that are currently batched. Eventually, when the batchis sent to VIOS, the call to netdev_tx_completed_queue() would increasenum_completed to a value greater than the num_queued. This causes aBUG_ON crash:ibmvnic 30000002: Firmware reports error, cause: adapter problem.Starting recovery...ibmvnic 30000002: tx error 600ibmvnic 30000002: tx error 600ibmvnic 30000002: tx error 600ibmvnic 30000002: tx error 600------------[ cut here ]------------kernel BUG at lib/dynamic_queue_limits.c:27!Oops: Exception in kernel mode, sig: 5[....]NIP dql_completed+0x28/0x1c0LR ibmvnic_complete_tx.isra.0+0x23c/0x420 [ibmvnic]Call Trace:ibmvnic_complete_tx.isra.0+0x3f8/0x420 [ibmvnic] (unreliable)ibmvnic_interrupt_tx+0x40/0x70 [ibmvnic]__handle_irq_event_percpu+0x98/0x270---[ end trace ]---Therefore, do not reset the dql stats when performing a NON_FATAL reset.

CVE-2023-53496 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:x86/platform/uv: Use alternate source for socket to node dataThe UV code attempts to build a set of tables to allow it to dobidirectional socket<=>node lookups.But when nr_cpus is set to a smaller number than actually present, thecpu_to_node() mapping information for unused CPUs is not available tobuild_socket_tables(). This results in skipping some nodes or socketswhen creating the tables and leaving some -1's for later code to trip.over, causing oopses.The problem is that the socket<=>node lookups are created by doing aloop over all CPUs, then looking up the CPU's APICID and socket. Butif a CPU is not present, there is no way to start this lookup.Instead of looping over all CPUs, take CPUs out of the equationentirely. Loop over all APICIDs which are mapped to a valid NUMA node.Then just extract the socket-id from the APICID.This avoid tripping over disabled CPUs.

CVE-2023-53516 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:macvlan: add forgotten nla_policy for IFLA_MACVLAN_BC_CUTOFFThe previous commit 954d1fa1ac93 ("macvlan: Add netlink attribute forbroadcast cutoff") added one additional attribute namedIFLA_MACVLAN_BC_CUTOFF to allow broadcast cutfoff.However, it forgot to describe the nla_policy at macvlan_policy(drivers/net/macvlan.c). Hence, this suppose NLA_S32 (4 bytes) integercan be faked as empty (0 bytes) by a malicious user, which could leadsto OOB in heap just like CVE-2023-3773.To fix it, this commit just completes the nla_policy description forIFLA_MACVLAN_BC_CUTOFF. This enforces the length check and avoids thepotential OOB read.

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

Description: In the Linux kernel, the following vulnerability has been resolved:ip_vti: fix potential slab-use-after-free in decode_session6When ip_vti device is set to the qdisc of the sfb type, the cb fieldof the sent skb may be modified during enqueuing. Then,slab-use-after-free may occur when ip_vti device sends IPv6 packets.As commit f855691975bb ("xfrm6: Fix the nexthdr offset in_decode_session6.") showed, xfrm_decode_session was originally intendedonly for the receive path. IP6CB(skb)->nhoff is not set duringtransmission. Therefore, set the cb field in the skb to 0 beforesending packets.

Description: In the Linux kernel, the following vulnerability has been resolved:tracing/histograms: Add histograms to hist_vars if they have referenced variablesHist triggers can have referenced variables without having directvariables fields. This can be the case if referenced variables are addedfor trigger actions. In this case the newly added references will nothave field variables. Not taking such referenced variables intoconsideration can result in a bug where it would be possible to removehist trigger with variables being refenced. This will result in a bugthat is easily reproducable like so$ cd /sys/kernel/tracing$ echo 'synthetic_sys_enter char[] comm; long id' >> synthetic_events$ echo 'hist:keys=common_pid.execname,id.syscall:vals=hitcount:comm=common_pid.execname' >> events/raw_syscalls/sys_enter/trigger$ echo 'hist:keys=common_pid.execname,id.syscall:onmatch(raw_syscalls.sys_enter).synthetic_sys_enter($comm, id)' >> events/raw_syscalls/sys_enter/trigger$ echo '!hist:keys=common_pid.execname,id.syscall:vals=hitcount:comm=common_pid.execname' >> events/raw_syscalls/sys_enter/trigger[ 100.263533] ==================================================================[ 100.264634] BUG: KASAN: slab-use-after-free in resolve_var_refs+0xc7/0x180[ 100.265520] Read of size 8 at addr ffff88810375d0f0 by task bash/439[ 100.266320][ 100.266533] CPU: 2 PID: 439 Comm: bash Not tainted 6.5.0-rc1 #4[ 100.267277] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.0-20220807_005459-localhost 04/01/2014[ 100.268561] Call Trace:[ 100.268902] [ 100.269189] dump_stack_lvl+0x4c/0x70[ 100.269680] print_report+0xc5/0x600[ 100.270165] ? resolve_var_refs+0xc7/0x180[ 100.270697] ? kasan_complete_mode_report_info+0x80/0x1f0[ 100.271389] ? resolve_var_refs+0xc7/0x180[ 100.271913] kasan_report+0xbd/0x100[ 100.272380] ? resolve_var_refs+0xc7/0x180[ 100.272920] __asan_load8+0x71/0xa0[ 100.273377] resolve_var_refs+0xc7/0x180[ 100.273888] event_hist_trigger+0x749/0x860[ 100.274505] ? kasan_save_stack+0x2a/0x50[ 100.275024] ? kasan_set_track+0x29/0x40[ 100.275536] ? __pfx_event_hist_trigger+0x10/0x10[ 100.276138] ? ksys_write+0xd1/0x170[ 100.276607] ? do_syscall_64+0x3c/0x90[ 100.277099] ? entry_SYSCALL_64_after_hwframe+0x6e/0xd8[ 100.277771] ? destroy_hist_data+0x446/0x470[ 100.278324] ? event_hist_trigger_parse+0xa6c/0x3860[ 100.278962] ? __pfx_event_hist_trigger_parse+0x10/0x10[ 100.279627] ? __kasan_check_write+0x18/0x20[ 100.280177] ? mutex_unlock+0x85/0xd0[ 100.280660] ? __pfx_mutex_unlock+0x10/0x10[ 100.281200] ? kfree+0x7b/0x120[ 100.281619] ? ____kasan_slab_free+0x15d/0x1d0[ 100.282197] ? event_trigger_write+0xac/0x100[ 100.282764] ? __kasan_slab_free+0x16/0x20[ 100.283293] ? __kmem_cache_free+0x153/0x2f0[ 100.283844] ? sched_mm_cid_remote_clear+0xb1/0x250[ 100.284550] ? __pfx_sched_mm_cid_remote_clear+0x10/0x10[ 100.285221] ? event_trigger_write+0xbc/0x100[ 100.285781] ? __kasan_check_read+0x15/0x20[ 100.286321] ? __bitmap_weight+0x66/0xa0[ 100.286833] ? _find_next_bit+0x46/0xe0[ 100.287334] ? task_mm_cid_work+0x37f/0x450[ 100.287872] event_triggers_call+0x84/0x150[ 100.288408] trace_event_buffer_commit+0x339/0x430[ 100.289073] ? ring_buffer_event_data+0x3f/0x60[ 100.292189] trace_event_raw_event_sys_enter+0x8b/0xe0[ 100.295434] syscall_trace_enter.constprop.0+0x18f/0x1b0[ 100.298653] syscall_enter_from_user_mode+0x32/0x40[ 100.301808] do_syscall_64+0x1a/0x90[ 100.304748] entry_SYSCALL_64_after_hwframe+0x6e/0xd8[ 100.307775] RIP: 0033:0x7f686c75c1cb[ 100.310617] Code: 73 01 c3 48 8b 0d 65 3c 10 00 f7 d8 64 89 01 48 83 c8 ff c3 66 2e 0f 1f 84 00 00 00 00 00 90 f3 0f 1e fa b8 21 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d 35 3c 10 00 f7 d8 64 89 01 48[ 100.317847] RSP: 002b:00007ffc60137a38 EFLAGS: 00000246 ORIG_RAX: 0000000000000021[ 100.321200] RA---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:cpufreq: amd-pstate-ut: Fix kernel panic when loading the driverAfter loading the amd-pstate-ut driver, amd_pstate_ut_check_perf()and amd_pstate_ut_check_freq() use cpufreq_cpu_get() to get the policyof the CPU and mark it as busy.In these functions, cpufreq_cpu_put() should be used to release thepolicy, but it is not, so any other entity trying to access the policyis blocked indefinitely.One such scenario is when amd_pstate mode is changed, leading to thefollowing splat:[ 1332.103727] INFO: task bash:2929 blocked for more than 120 seconds.[ 1332.110001] Not tainted 6.5.0-rc2-amd-pstate-ut #5[ 1332.115315] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.[ 1332.123140] task:bash state:D stack:0 pid:2929 ppid:2873 flags:0x00004006[ 1332.123143] Call Trace:[ 1332.123145] [ 1332.123148] __schedule+0x3c1/0x16a0[ 1332.123154] ? _raw_read_lock_irqsave+0x2d/0x70[ 1332.123157] schedule+0x6f/0x110[ 1332.123160] schedule_timeout+0x14f/0x160[ 1332.123162] ? preempt_count_add+0x86/0xd0[ 1332.123165] __wait_for_common+0x92/0x190[ 1332.123168] ? __pfx_schedule_timeout+0x10/0x10[ 1332.123170] wait_for_completion+0x28/0x30[ 1332.123173] cpufreq_policy_put_kobj+0x4d/0x90[ 1332.123177] cpufreq_policy_free+0x157/0x1d0[ 1332.123178] ? preempt_count_add+0x58/0xd0[ 1332.123180] cpufreq_remove_dev+0xb6/0x100[ 1332.123182] subsys_interface_unregister+0x114/0x120[ 1332.123185] ? preempt_count_add+0x58/0xd0[ 1332.123187] ? __pfx_amd_pstate_change_driver_mode+0x10/0x10[ 1332.123190] cpufreq_unregister_driver+0x3b/0xd0[ 1332.123192] amd_pstate_change_driver_mode+0x1e/0x50[ 1332.123194] store_status+0xe9/0x180[ 1332.123197] dev_attr_store+0x1b/0x30[ 1332.123199] sysfs_kf_write+0x42/0x50[ 1332.123202] kernfs_fop_write_iter+0x143/0x1d0[ 1332.123204] vfs_write+0x2df/0x400[ 1332.123208] ksys_write+0x6b/0xf0[ 1332.123210] __x64_sys_write+0x1d/0x30[ 1332.123213] do_syscall_64+0x60/0x90[ 1332.123216] ? fpregs_assert_state_consistent+0x2e/0x50[ 1332.123219] ? exit_to_user_mode_prepare+0x49/0x1a0[ 1332.123223] ? irqentry_exit_to_user_mode+0xd/0x20[ 1332.123225] ? irqentry_exit+0x3f/0x50[ 1332.123226] ? exc_page_fault+0x8e/0x190[ 1332.123228] entry_SYSCALL_64_after_hwframe+0x6e/0xd8[ 1332.123232] RIP: 0033:0x7fa74c514a37[ 1332.123234] RSP: 002b:00007ffe31dd0788 EFLAGS: 00000246 ORIG_RAX: 0000000000000001[ 1332.123238] RAX: ffffffffffffffda RBX: 0000000000000008 RCX: 00007fa74c514a37[ 1332.123239] RDX: 0000000000000008 RSI: 000055e27c447aa0 RDI: 0000000000000001[ 1332.123241] RBP: 000055e27c447aa0 R08: 00007fa74c5d1460 R09: 000000007fffffff[ 1332.123242] R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000008[ 1332.123244] R13: 00007fa74c61a780 R14: 00007fa74c616600 R15: 00007fa74c615a00[ 1332.123247] Fix this by calling cpufreq_cpu_put() wherever necessary.[ rjw: Subject and changelog edits ]

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: nl80211: fix integer overflow in nl80211_parse_mbssid_elems()nl80211_parse_mbssid_elems() uses a u8 variable num_elems to count thenumber of MBSSID elements in the nested netlink attribute attrs, which canlead to an integer overflow if a user of the nl80211 interface specifies256 or more elements in the corresponding attribute in userspace. Theinteger overflow can lead to a heap buffer overflow as num_elems determinesthe size of the trailing array in elems, and this array is thereafterwritten to for each element in attrs.Note that this vulnerability only affects devices with thewiphy->mbssid_max_interfaces member set for the wireless physical devicestruct in the device driver, and can only be triggered by a process withCAP_NET_ADMIN capabilities.Fix this by checking for a maximum of 255 elements in attrs.

The kthread is stopped prematurely bykthread_stop() in cpu_map_kthread_stop(), and kthread() doesn't callcpu_map_kthread_run() at all but XDP program has already queued someframes or skbs into ptr_ring. So when __cpu_map_ring_cleanup() checksthe ptr_ring, it will find it was not emptied and report a warning.An alternative fix is to use __cpu_map_ring_cleanup() to drop thesepending frames or skbs when kthread_stop() returns -EINTR, but it mayconfuse the user, because these frames or skbs have been handledcorrectly by XDP program. So instead of dropping these frames or skbs,just make sure the per-cpu kthread is running before__cpu_map_entry_alloc() returns.After apply the fix, the error handle for kthread_stop() will beunnecessary because it will always return 0, so just remove it.

CVE-2023-53580 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:USB: Gadget: core: Help prevent panic during UVC unconfigureAvichal Rakesh reported a kernel panic that occurred when the UVCgadget driver was removed from a gadget's configuration. The panicinvolves a somewhat complicated interaction between the kernel driverand a userspace component (as described in the Link tag below), butthe analysis did make one thing clear: The Gadget core shouldaccomodate gadget drivers calling usb_gadget_deactivate() as part oftheir unbind procedure.Currently this doesn't work. gadget_unbind_driver() callsdriver->unbind() while holding the udc->connect_lock mutex, andusb_gadget_deactivate() attempts to acquire that mutex, which willresult in a deadlock.The simple fix is for gadget_unbind_driver() to release the mutex wheninvoking the ->unbind() callback. There is no particular reason forit to be holding the mutex at that time, and the mutex isn't heldwhile the ->bind() callback is invoked. So we'll drop the mutexbefore performing the unbind callback and reacquire it afterward.We'll also add a couple of comments to usb_gadget_activate() andusb_gadget_deactivate(). Because they run in process context theymust not be called from a gadget driver's ->disconnect() callback,which (according to the kerneldoc for struct usb_gadget_driver ininclude/linux/usb/gadget.h) may run in interrupt context. This mayhelp prevent similar bugs from arising in the future.

CVE-2023-53593 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:cifs: Release folio lock on fscache read hit.Under the current code, when cifs_readpage_worker is called, the callcontract is that the callee should unlock the page. This is documentedin the read_folio section of Documentation/filesystems/vfs.rst as:> The filesystem should unlock the folio once the read has completed,> whether it was successful or not.Without this change, when fscache is in use and cache hit occurs duringa read, the page lock is leaked, producing the following stack onsubsequent reads (via mmap) to the page:$ cat /proc/3890/task/12864/stack[<0>] folio_wait_bit_common+0x124/0x350[<0>] filemap_read_folio+0xad/0xf0[<0>] filemap_fault+0x8b1/0xab0[<0>] __do_fault+0x39/0x150[<0>] do_fault+0x25c/0x3e0[<0>] __handle_mm_fault+0x6ca/0xc70[<0>] handle_mm_fault+0xe9/0x350[<0>] do_user_addr_fault+0x225/0x6c0[<0>] exc_page_fault+0x84/0x1b0[<0>] asm_exc_page_fault+0x27/0x30This requires a reboot to resolve; it is a deadlock.Note however that the call to cifs_readpage_from_fscache does mark thepage clean, but does not free the folio lock. This happens in__cifs_readpage_from_fscache on success. Releasing the lock at thatpoint however is not appropriate as cifs_readahead also callscifs_readpage_from_fscache and *does* unconditionally release the lockafter its return. This change therefore effectively makescifs_readpage_worker work like cifs_readahead.

CVE-2023-53596 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:drivers: base: Free devm resources when unregistering a deviceIn the current code, devres_release_all() only gets called if the devicehas a bus and has been probed.This leads to issues when using bus-less or driver-less devices wherethe device might never get freed if a managed resource holds a referenceto the device. This is happening in the DRM framework for example.We should thus call devres_release_all() in the device_del() function tomake sure that the device-managed actions are properly executed when thedevice is unregistered, even if it has neither a bus nor a driver.This is effectively the same change than commit 2f8d16a996da ("devres:release resources on device_del()") that got reverted by commita525a3ddeaca ("driver core: free devres in device_release") overmemory leaks concerns.This patch effectively combines the two commits mentioned above torelease the resources both on device_del() and device_release() and getthe best of both worlds.

CVE-2023-53597 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:cifs: fix mid leak during reconnection after timeout thresholdWhen the number of responses with status of STATUS_IO_TIMEOUTexceeds a specified threshold (NUM_STATUS_IO_TIMEOUT), we reconnectthe connection. But we do not return the mid, or the creditsreturned for the mid, or reduce the number of in-flight requests.This bug could result in the server->in_flight count to go bad,and also cause a leak in the mids.This change moves the check to a few lines below where theresponse is decrypted, even of the response is read from thetransform header. This way, the code for returning the midscan be reused.Also, the cifs_reconnect was reconnecting just the transportconnection before. In case of multi-channel, this may not bewhat we want to do after several timeouts. Changed that toreconnect the session and the tree too.Also renamed NUM_STATUS_IO_TIMEOUT to a more appropriate nameMAX_STATUS_IO_TIMEOUT.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: reject invalid reloc tree root keys with stack dump[BUG]Syzbot reported a crash that an ASSERT() got triggered insideprepare_to_merge().That ASSERT() makes sure the reloc tree is properly pointed back by itssubvolume tree.[CAUSE]After more debugging output, it turns out we had an invalid reloc tree: BTRFS error (device loop1): reloc tree mismatch, root 8 has no reloc root, expect reloc root key (-8, 132, 8) gen 17Note the above root key is (TREE_RELOC_OBJECTID, ROOT_ITEM,QUOTA_TREE_OBJECTID), meaning it's a reloc tree for quota tree.But reloc trees can only exist for subvolumes, as for non-subvolumetrees, we just COW the involved tree block, no need to create a reloctree since those tree blocks won't be shared with other trees.Only subvolumes tree can share tree blocks with other trees (thus theyhave BTRFS_ROOT_SHAREABLE flag).Thus this new debug output proves my previous assumption that corruptedon-disk data can trigger that ASSERT().[FIX]Besides the dedicated fix and the graceful exit, also let tree-checker tocheck such root keys, to make sure reloc trees can only exist for subvolumes.

Description: In the Linux kernel, the following vulnerability has been resolved:memcontrol: ensure memcg acquired by id is properly set upIn the eviction recency check, we attempt to retrieve the memcg to whichthe folio belonged when it was evicted, by the memcg id stored in theshadow entry. However, there is a chance that the retrieved memcg is notthe original memcg that has been killed, but a new one which happens tohave the same id.This is a somewhat unfortunate, but acceptable and rare inaccuracy in theheuristics. However, if we retrieve this new memcg between its allocationand when it is properly attached to the memcg hierarchy, we could run intothe following NULL pointer exception during the memcg hierarchy traversaldone in mem_cgroup_get_nr_swap_pages():[ 155757.793456] BUG: kernel NULL pointer dereference, address: 00000000000000c0[ 155757.807568] #PF: supervisor read access in kernel mode[ 155757.818024] #PF: error_code(0x0000) - not-present page[ 155757.828482] PGD 401f77067 P4D 401f77067 PUD 401f76067 PMD 0[ 155757.839985] Oops: 0000 [#1] SMP[ 155757.887870] RIP: 0010:mem_cgroup_get_nr_swap_pages+0x3d/0xb0[ 155757.899377] Code: 29 19 4a 02 48 39 f9 74 63 48 8b 97 c0 00 00 00 48 8b b7 58 02 00 00 48 2b b7 c0 01 00 00 48 39 f0 48 0f 4d c6 48 39 d1 74 42 <48> 8b b2 c0 00 00 00 48 8b ba 58 02 00 00 48 2b ba c0 01 00 00 48[ 155757.937125] RSP: 0018:ffffc9002ecdfbc8 EFLAGS: 00010286[ 155757.947755] RAX: 00000000003a3b1c RBX: 000007ffffffffff RCX: ffff888280183000[ 155757.962202] RDX: 0000000000000000 RSI: 0007ffffffffffff RDI: ffff888bbc2d1000[ 155757.976648] RBP: 0000000000000001 R08: 000000000000000b R09: ffff888ad9cedba0[ 155757.991094] R10: ffffea0039c07900 R11: 0000000000000010 R12: ffff888b23a7b000[ 155758.005540] R13: 0000000000000000 R14: ffff888bbc2d1000 R15: 000007ffffc71354[ 155758.019991] FS: 00007f6234c68640(0000) GS:ffff88903f9c0000(0000) knlGS:0000000000000000[ 155758.036356] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 155758.048023] CR2: 00000000000000c0 CR3: 0000000a83eb8004 CR4: 00000000007706e0[ 155758.062473] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 155758.076924] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[ 155758.091376] PKRU: 55555554[ 155758.096957] Call Trace:[ 155758.102016] [ 155758.106502] ? __die+0x78/0xc0[ 155758.112793] ? page_fault_oops+0x286/0x380[ 155758.121175] ? exc_page_fault+0x5d/0x110[ 155758.129209] ? asm_exc_page_fault+0x22/0x30[ 155758.137763] ? mem_cgroup_get_nr_swap_pages+0x3d/0xb0[ 155758.148060] workingset_test_recent+0xda/0x1b0[ 155758.157133] workingset_refault+0xca/0x1e0[ 155758.165508] filemap_add_folio+0x4d/0x70[ 155758.173538] page_cache_ra_unbounded+0xed/0x190[ 155758.182919] page_cache_sync_ra+0xd6/0x1e0[ 155758.191738] filemap_read+0x68d/0xdf0[ 155758.199495] ? mlx5e_napi_poll+0x123/0x940[ 155758.207981] ? __napi_schedule+0x55/0x90[ 155758.216095] __x64_sys_pread64+0x1d6/0x2c0[ 155758.224601] do_syscall_64+0x3d/0x80[ 155758.232058] entry_SYSCALL_64_after_hwframe+0x46/0xb0[ 155758.242473] RIP: 0033:0x7f62c29153b5[ 155758.249938] Code: e8 48 89 75 f0 89 7d f8 48 89 4d e0 e8 b4 e6 f7 ff 41 89 c0 4c 8b 55 e0 48 8b 55 e8 48 8b 75 f0 8b 7d f8 b8 11 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 33 44 89 c7 48 89 45 f8 e8 e7 e6 f7 ff 48 8b[ 155758.288005] RSP: 002b:00007f6234c5ffd0 EFLAGS: 00000293 ORIG_RAX: 0000000000000011[ 155758.303474] RAX: ffffffffffffffda RBX: 00007f628c4e70c0 RCX: 00007f62c29153b5[ 155758.318075] RDX: 000000000003c041 RSI: 00007f61d2986000 RDI: 0000000000000076[ 155758.332678] RBP: 00007f6234c5fff0 R08: 0000000000000000 R09: 0000000064d5230c[ 155758.347452] R10: 000000000027d450 R11: 0000000000000293 R12: 000000000003c041[ 155758.362044] R13: 00007f61d2986000 R14: 00007f629e11b060 R15: 000000000027d450[ 155758.376661] This patch fixes the issue by moving the memcg's id publication from thealloc stage to ---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:octeon_ep: cancel queued works in probe error pathIf it fails to get the devices's MAC address, octep_probe exits whileleaving the delayed work intr_poll_task queued. When the work laterruns, it's a use after free.Move the cancelation of intr_poll_task from octep_remove intooctep_device_cleanup. This does not change anything in the octep_removeflow, but octep_device_cleanup is called also in the octep_probe errorpath, where the cancelation is needed.Note that the cancelation of ctrl_mbox_task has to followintr_poll_task's, because the ctrl_mbox_task may be queued byintr_poll_task.

CVE-2023-53645 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Make bpf_refcount_acquire fallible for non-owning refsThis patch fixes an incorrect assumption made in the originalbpf_refcount series [0], specifically that the BPF program callingbpf_refcount_acquire on some node can always guarantee that the node isalive. In that series, the patch adding failure behavior to rbtree_addand list_push_{front, back} breaks this assumption for non-owningreferences.Consider the following program: n = bpf_kptr_xchg(&mapval, NULL); /* skip error checking */ bpf_spin_lock(&l); if(bpf_rbtree_add(&t, &n->rb, less)) { bpf_refcount_acquire(n); /* Failed to add, do something else with the node */ } bpf_spin_unlock(&l);It's incorrect to assume that bpf_refcount_acquire will always succeed in thisscenario. bpf_refcount_acquire is being called in a critical sectionhere, but the lock being held is associated with rbtree t, which isn'tnecessarily the lock associated with the tree that the node is alreadyin. So after bpf_rbtree_add fails to add the node and calls bpf_obj_dropin it, the program has no ownership of the node's lifetime. Thereforethe node's refcount can be decr'd to 0 at any time after the failingrbtree_add. If this happens before the refcount_acquire above, the nodemight be free'd, and regardless refcount_acquire will be incrementing a0 refcount.Later patches in the series exercise this scenario, resulting in theexpected complaint from the kernel (without this patch's changes): refcount_t: addition on 0; use-after-free.

Some verifierbookkeeping is added to track "is input owning ref?" for bpf_refcount_acquirecalls and return false from is_kfunc_ret_null for bpf_refcount_acquire onowning refs despite it being marked KF_RET_NULL.Existing selftests using bpf_refcount_acquire are modified wherenecessary to NULL-check its return value.

CVE-2023-53647 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:Drivers: hv: vmbus: Don't dereference ACPI root object handleSince the commit referenced in the Fixes: tag below the VMBus client driveris walking the ACPI namespace up from the VMBus ACPI device to the ACPInamespace root object trying to find Hyper-V MMIO ranges.However, if it is not able to find them it ends trying to walk resources ofthe ACPI namespace root object itself.This object has all-ones handle, which causes a NULL pointer dereferencein the ACPI code (from dereferencing this pointer with an offset).This in turn causes an oops on boot with VMBus host implementations that donot provide Hyper-V MMIO ranges in their VMBus ACPI device or itsancestors.The QEMU VMBus implementation is an example of such implementation.I guess providing these ranges is optional, since all tested Windowsversions seem to be able to use VMBus devices without them.Fix this by explicitly terminating the lookup at the ACPI namespace rootobject.Note that Linux guests under KVM/QEMU do not use the Hyper-V PV interfaceby default - they only do so if the KVM PV interface is missing ordisabled.Example stack trace of such oops:[ 3.710827] ? __die+0x1f/0x60[ 3.715030] ? page_fault_oops+0x159/0x460[ 3.716008] ? exc_page_fault+0x73/0x170[ 3.716959] ? asm_exc_page_fault+0x22/0x30[ 3.717957] ? acpi_ns_lookup+0x7a/0x4b0[ 3.718898] ? acpi_ns_internalize_name+0x79/0xc0[ 3.720018] acpi_ns_get_node_unlocked+0xb5/0xe0[ 3.721120] ? acpi_ns_check_object_type+0xfe/0x200[ 3.722285] ? acpi_rs_convert_aml_to_resource+0x37/0x6e0[ 3.723559] ? down_timeout+0x3a/0x60[ 3.724455] ? acpi_ns_get_node+0x3a/0x60[ 3.725412] acpi_ns_get_node+0x3a/0x60[ 3.726335] acpi_ns_evaluate+0x1c3/0x2c0[ 3.727295] acpi_ut_evaluate_object+0x64/0x1b0[ 3.728400] acpi_rs_get_method_data+0x2b/0x70[ 3.729476] ? vmbus_platform_driver_probe+0x1d0/0x1d0 [hv_vmbus][ 3.730940] ? vmbus_platform_driver_probe+0x1d0/0x1d0 [hv_vmbus][ 3.732411] acpi_walk_resources+0x78/0xd0[ 3.733398] vmbus_platform_driver_probe+0x9f/0x1d0 [hv_vmbus][ 3.734802] platform_probe+0x3d/0x90[ 3.735684] really_probe+0x19b/0x400[ 3.736570] ? __device_attach_driver+0x100/0x100[ 3.737697] __driver_probe_device+0x78/0x160[ 3.738746] driver_probe_device+0x1f/0x90[ 3.739743] __driver_attach+0xc2/0x1b0[ 3.740671] bus_for_each_dev+0x70/0xc0[ 3.741601] bus_add_driver+0x10e/0x210[ 3.742527] driver_register+0x55/0xf0[ 3.744412] ? 0xffffffffc039a000[ 3.745207] hv_acpi_init+0x3c/0x1000 [hv_vmbus]

CVE-2023-53658 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:spi: bcm-qspi: return error if neither hif_mspi nor mspi is availableIf neither a "hif_mspi" nor "mspi" resource is present, the driver willjust early exit in probe but still return success. Apart from not doinganything meaningful, this would then also lead to a null pointer accesson removal, as platform_get_drvdata() would return NULL, which it wouldthen try to dereference when trying to unregister the spi master.Fix this by unconditionally calling devm_ioremap_resource(), as it canhandle a NULL res and will then return a viable ERR_PTR() if we get one.The "return 0;" was previously a "goto qspi_resource_err;" where thenret was returned, but since ret was still initialized to 0 at this placethis was a valid conversion in 63c5395bb7a9 ("spi: bcm-qspi: Fixuse-after-free on unbind"). The issue was not introduced by this commit,only made more obvious.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: output extra debug info if we failed to find an inline backref[BUG]Syzbot reported several warning triggered insidelookup_inline_extent_backref().[CAUSE]As usual, the reproducer doesn't reliably trigger locally here, but atleast we know the WARN_ON() is triggered when an inline backref can notbe found, and it can only be triggered when @insert is true. (I.e.inserting a new inline backref, which means the backref should alreadyexist)[ENHANCEMENT]After the WARN_ON(), dump all the parameters and the extent treeleaf to help debug.

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

Description: In the Linux kernel, the following vulnerability has been resolved:tcp: correct handling of extreme memory squeezeTesting with iperf3 using the "pasta" protocol splicer has revealeda problem in the way tcp handles window advertising in extreme memorysqueeze situations.Under memory pressure, a socket endpoint may temporarily advertisea zero-sized window, but this is not stored as part of the socket data.The reasoning behind this is that it is considered a temporary settingwhich shouldn't influence any further calculations.However, if we happen to stall at an unfortunate value of the currentwindow size, the algorithm selecting a new value will consistently failto advertise a non-zero window once we have freed up enough memory.This means that this side's notion of the current window size isdifferent from the one last advertised to the peer, causing the latterto not send any data to resolve the sitution.The problem occurs on the iperf3 server side, and the socket in questionis a completely regular socket with the default settings for thefedora40 kernel. We do not use SO_PEEK or SO_RCVBUF on the socket.The following excerpt of a logging session, with own comments added,shows more in detail what is happening:// tcp_v4_rcv(->)// tcp_rcv_established(->)[5201<->39222]: ==== Activating log @ net/ipv4/tcp_input.c/tcp_data_queue()/5257 ====[5201<->39222]: tcp_data_queue(->)[5201<->39222]: DROPPING skb [265600160..265665640], reason: SKB_DROP_REASON_PROTO_MEM [rcv_nxt 265600160, rcv_wnd 262144, snt_ack 265469200, win_now 131184] [copied_seq 259909392->260034360 (124968), unread 5565800, qlen 85, ofoq 0] [OFO queue: gap: 65480, len: 0][5201<->39222]: tcp_data_queue(<-)[5201<->39222]: __tcp_transmit_skb(->) [tp->rcv_wup: 265469200, tp->rcv_wnd: 262144, tp->rcv_nxt 265600160][5201<->39222]: tcp_select_window(->)[5201<->39222]: (inet_csk(sk)->icsk_ack.pending & ICSK_ACK_NOMEM) ? --> TRUE [tp->rcv_wup: 265469200, tp->rcv_wnd: 262144, tp->rcv_nxt 265600160] returning 0[5201<->39222]: tcp_select_window(<-)[5201<->39222]: ADVERTISING WIN 0, ACK_SEQ: 265600160[5201<->39222]: [__tcp_transmit_skb(<-)[5201<->39222]: tcp_rcv_established(<-)[5201<->39222]: tcp_v4_rcv(<-)// Receive queue is at 85 buffers and we are out of memory.// We drop the incoming buffer, although it is in sequence, and decide// to send an advertisement with a window of zero.// We don't update tp->rcv_wnd and tp->rcv_wup accordingly, which means// we unconditionally shrink the window.[5201<->39222]: tcp_recvmsg_locked(->)[5201<->39222]: __tcp_cleanup_rbuf(->) tp->rcv_wup: 265469200, tp->rcv_wnd: 262144, tp->rcv_nxt 265600160[5201<->39222]: [new_win = 0, win_now = 131184, 2 * win_now = 262368][5201<->39222]: [new_win >= (2 * win_now) ? --> time_to_ack = 0][5201<->39222]: NOT calling tcp_send_ack() [tp->rcv_wup: 265469200, tp->rcv_wnd: 262144, tp->rcv_nxt 265600160][5201<->39222]: __tcp_cleanup_rbuf(<-) [rcv_nxt 265600160, rcv_wnd 262144, snt_ack 265469200, win_now 131184] [copied_seq 260040464->260040464 (0), unread 5559696, qlen 85, ofoq 0] returning 6104 bytes[5201<->39222]: tcp_recvmsg_locked(<-)// After each read, the algorithm for calculating the new receive// window in __tcp_cleanup_rbuf() finds it is too small to advertise// or to update tp->rcv_wnd.// Meanwhile, the peer thinks the window is zero, and will not send// any more data to trigger an update from the interrupt mode side.[5201<->39222]: tcp_recvmsg_locked(->)[5201<->39222]: __tcp_cleanup_rbuf(->) tp->rcv_wup: 265469200, tp->rcv_wnd: 262144, tp->rcv_nxt 265600160[5201<->39222]: [new_win = 262144, win_now = 131184, 2 * win_n---truncated---

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:nfsd: handle get_client_locked() failure in nfsd4_setclientid_confirm()Lei Lu recently reported that nfsd4_setclientid_confirm() did not checkthe return value from get_client_locked(). a SETCLIENTID_CONFIRM couldrace with a confirmed client expiring and fail to get a reference. Thatcould later lead to a UAF.Fix this by getting a reference early in the case where there is anextant confirmed client. If that fails then treat it as if there were noconfirmed client found at all.In the case where the unconfirmed client is expiring, just fail andreturn the result from get_client_locked().

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

CVE-2025-38735 Severity: Moderate CVSS3 score: 5.5

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

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

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

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

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

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

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

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

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

CVE-2025-39713 Severity: Moderate CVSS3 score: 5.5

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

In the case ofbno055_gyr_scale, the vals array is larger than the hw_xlate array,so this could result in an out-of-bounds access. In practice, thisshouldn't happen though because a match should always be found whichbreaks out of the for loop before it iterates beyond the end of thehw_xlate array.By adding a new hw_xlate_len field to the bno055_sysfs_attr, we can besure we are iterating over the correct length.

CVE-2025-39721 Severity: Moderate CVSS3 score: 5.5

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

Description: In the Linux kernel, the following vulnerability has been resolved:serial: 8250: fix panic due to PSLVERRWhen the PSLVERR_RESP_EN parameter is set to 1, the device generatesan error response if an attempt is made to read an empty RBR (ReceiveBuffer Register) while the FIFO is enabled.In serial8250_do_startup(), calling serial_port_out(port, UART_LCR,UART_LCR_WLEN8) triggers dw8250_check_lcr(), which invokesdw8250_force_idle() and serial8250_clear_and_reinit_fifos().

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

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

CVE-2025-39756 Severity: Moderate CVSS3 score: 5.5

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

Description: In the Linux kernel, the following vulnerability has been resolved:net: macb: fix unregister_netdev call order in macb_remove()When removing a macb device, the driver calls phy_exit() beforeunregister_netdev(). This leads to a WARN from kernfs: ------------[ cut here ]------------ kernfs: can not remove 'attached_dev', no directory WARNING: CPU: 1 PID: 27146 at fs/kernfs/dir.c:1683 Call trace: kernfs_remove_by_name_ns+0xd8/0xf0 sysfs_remove_link+0x24/0x58 phy_detach+0x5c/0x168 phy_disconnect+0x4c/0x70 phylink_disconnect_phy+0x6c/0xc0 [phylink] macb_close+0x6c/0x170 [macb] ... macb_remove+0x60/0x168 [macb] platform_remove+0x5c/0x80 ...The warning happens because the PHY is being exited while the netdevis still registered.

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

Description: In the Linux kernel, the following vulnerability has been resolved:ftrace: Fix potential warning in trace_printk_seq during ftrace_dumpWhen calling ftrace_dump_one() concurrently with reading trace_pipe,a WARN_ON_ONCE() in trace_printk_seq() can be triggered due to a racecondition.The issue occurs because:CPU0 (ftrace_dump) CPU1 (reader)echo z > /proc/sysrq-trigger!trace_empty(&iter)trace_iterator_reset(&iter) <- len = size = 0 cat /sys/kernel/tracing/trace_pipetrace_find_next_entry_inc(&iter) __find_next_entry ring_buffer_empty_cpu <- all empty return NULLtrace_printk_seq(&iter.seq) WARN_ON_ONCE(s->seq.len >= s->seq.size)In the context between trace_empty() and trace_find_next_entry_inc()during ftrace_dump, the ring buffer data was consumed by other readers.This caused trace_find_next_entry_inc to return NULL, failing to populate`iter.seq`. At this point, due to the prior trace_iterator_reset, both`iter.seq.len` and `iter.seq.size` were set to 0. Since they are equal,the WARN_ON_ONCE condition is triggered.Move the trace_printk_seq() into the if block that checks to make sure thereturn value of trace_find_next_entry_inc() is non-NULL inftrace_dump_one(), ensuring the 'iter.seq' is properly populated beforesubsequent operations.

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

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

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

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

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

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

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

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

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

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

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

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

However theymight not intersect if all CPUs in the cpus mask are offline. bsearchwill return NULL in that case, bail out instead of dereferencing abogus pointer.The previous behaviour lead to this bug when using maxcpus=4 on anrk3399 (LLLLbb) (i.e. booting with all big CPUs offline):[ 1.422922] Unable to handle kernel paging request at virtual address ffffff8000000000[ 1.423635] Mem abort info:[ 1.423889] ESR = 0x0000000096000006[ 1.424227] EC = 0x25: DABT (current EL), IL = 32 bits[ 1.424715] SET = 0, FnV = 0[ 1.424995] EA = 0, S1PTW = 0[ 1.425279] FSC = 0x06: level 2 translation fault[ 1.425735] Data abort info:[ 1.425998] ISV = 0, ISS = 0x00000006, ISS2 = 0x00000000[ 1.426499] CM = 0, WnR = 0, TnD = 0, TagAccess = 0[ 1.426952] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0[ 1.427428] swapper pgtable: 4k pages, 39-bit VAs, pgdp=0000000004a9f000[ 1.428038] [ffffff8000000000] pgd=18000000f7fff403, p4d=18000000f7fff403, pud=18000000f7fff403, pmd=0000000000000000[ 1.429014] Internal error: Oops: 0000000096000006 [#1] SMP[ 1.429525] Modules linked in:[ 1.429813] CPU: 3 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.17.0-rc4-dirty #343 PREEMPT[ 1.430559] Hardware name: Pine64 RockPro64 v2.1 (DT)[ 1.431012] pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--)[ 1.431634] pc : sched_numa_find_nth_cpu+0x2a0/0x488[ 1.432094] lr : sched_numa_find_nth_cpu+0x284/0x488[ 1.432543] sp : ffffffc084e1b960[ 1.432843] x29: ffffffc084e1b960 x28: ffffff80078a8800 x27: ffffffc0846eb1d0[ 1.433495] x26: 0000000000000000 x25: 0000000000000000 x24: 0000000000000000[ 1.434144] x23: 0000000000000000 x22: fffffffffff7f093 x21: ffffffc081de6378[ 1.434792] x20: 0000000000000000 x19: 0000000ffff7f093 x18: 00000000ffffffff[ 1.435441] x17: 3030303866666666 x16: 66663d736b73616d x15: ffffffc104e1b5b7[ 1.436091] x14: 0000000000000000 x13: ffffffc084712860 x12: 0000000000000372[ 1.436739] x11: 0000000000000126 x10: ffffffc08476a860 x9 : ffffffc084712860[ 1.437389] x8 : 00000000ffffefff x7 : ffffffc08476a860 x6 : 0000000000000000[ 1.438036] x5 : 000000000000bff4 x4 : 0000000000000000 x3 : 0000000000000000[ 1.438683] x2 : 0000000000000000 x1 : ffffffc0846eb000 x0 : ffffff8000407b68[ 1.439332] Call trace:[ 1.439559] sched_numa_find_nth_cpu+0x2a0/0x488 (P)[ 1.440016] smp_call_function_any+0xc8/0xd0[ 1.440416] armv8_pmu_init+0x58/0x27c[ 1.440770] armv8_cortex_a72_pmu_init+0x20/0x2c[ 1.441199] arm_pmu_device_probe+0x1e4/0x5e8[ 1.441603] armv8_pmu_device_probe+0x1c/0x28[ 1.442007] platform_probe+0x5c/0xac[ 1.442347] really_probe+0xbc/0x298[ 1.442683] __driver_probe_device+0x78/0x12c[ 1.443087] driver_probe_device+0xdc/0x160[ 1.443475] __driver_attach+0x94/0x19c[ 1.443833] bus_for_each_dev+0x74/0xd4[ 1.444190] driver_attach+0x24/0x30[ 1.444525] bus_add_driver+0xe4/0x208[ 1.444874] driver_register+0x60/0x128[ 1.445233] __platform_driver_register+0x24/0x30[ 1.445662] armv8_pmu_driver_init+0x28/0x4c[ 1.446059] do_one_initcall+0x44/0x25c[ 1.446416] kernel_init_freeable+0x1dc/0x3bc[ 1.446820] kernel_init+0x20/0x1d8[ 1.447151] ret_from_fork+0x10/0x20[ 1.447493] Code: 90022e21 f000e5f5 910de2b5 2a1703e2 (f8767803)[ 1.448040] ---[ end trace 0000000000000000 ]---[ 1.448483] note: swapper/0[1] exited with preempt_count 1[ 1.449047] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b[ 1.449741] SMP: stopping secondary CPUs[ 1.450105] Kernel Offset: disabled[ 1.450419] CPU features: 0x000000,00080000,20002001,0400421b[ ---truncated---

CVE-2025-39902 Severity: Moderate CVSS3 score: 5.5

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

If kmalloc() fails in add_interval(), it couldresult in a null pointer being inserted into the linked list,leading to illegal memory access when sub_interval() is callednext.This patch adds an error handling for the add_interval().

But we need to callj1939_priv_put() against an extra ref held by j1939_sk_bind() call(as a part of undoing changes made by j1939_sk_bind()) as soon asNETDEV_UNREGISTER notification fires (i.e. before j1939_sk_sock_destruct()is called via j1939_sk_release()). Otherwise, the extra ref on "structj1939_priv" held by j1939_sk_bind() call prevents "struct net_device" fromdropping the usage count to 1; making it impossible forunregister_netdevice() to continue.[mkl: remove space in front of label]

Not many x86 machines actually have a "BCM4752"/"LNV4752" acpi_device2. The stack happened to contain NULL where type_name is stored

This leads to use-after-free scenarioswhere otx2_ptp is deallocated by otx2_ptp_destroy(), while synctstamp_workremains active and attempts to dereference otx2_ptp in otx2_sync_tstamp().Furthermore, the synctstamp_work is cyclic, the likelihood of triggeringthe bug is nonnegligible.A typical race condition is illustrated below:CPU 0 (cleanup) | CPU 1 (delayed work callback)otx2_remove() | otx2_ptp_destroy() | otx2_sync_tstamp() cancel_delayed_work() | kfree(ptp) | | ptp = container_of(...); //UAF | ptp-> //UAFThis is confirmed by a KASAN report:BUG: KASAN: slab-use-after-free in __run_timer_base.part.0+0x7d7/0x8c0Write of size 8 at addr ffff88800aa09a18 by task bash/136...Call Trace: dump_stack_lvl+0x55/0x70 print_report+0xcf/0x610 ? __run_timer_base.part.0+0x7d7/0x8c0 kasan_report+0xb8/0xf0 ? __run_timer_base.part.0+0x7d7/0x8c0 __run_timer_base.part.0+0x7d7/0x8c0 ? __pfx___run_timer_base.part.0+0x10/0x10 ? __pfx_read_tsc+0x10/0x10 ? ktime_get+0x60/0x140 ? lapic_next_event+0x11/0x20 ? clockevents_program_event+0x1d4/0x2a0 run_timer_softirq+0xd1/0x190 handle_softirqs+0x16a/0x550 irq_exit_rcu+0xaf/0xe0 sysvec_apic_timer_interrupt+0x70/0x80 ...Allocated by task 1: kasan_save_stack+0x24/0x50 kasan_save_track+0x14/0x30 __kasan_kmalloc+0x7f/0x90 otx2_ptp_init+0xb1/0x860 otx2_probe+0x4eb/0xc30 local_pci_probe+0xdc/0x190 pci_device_probe+0x2fe/0x470 really_probe+0x1ca/0x5c0 __driver_probe_device+0x248/0x310 driver_probe_device+0x44/0x120 __driver_attach+0xd2/0x310 bus_for_each_dev+0xed/0x170 bus_add_driver+0x208/0x500 driver_register+0x132/0x460 do_one_initcall+0x89/0x300 kernel_init_freeable+0x40d/0x720 kernel_init+0x1a/0x150 ret_from_fork+0x10c/0x1a0 ret_from_fork_asm+0x1a/0x30Freed by task 136: kasan_save_stack+0x24/0x50 kasan_save_track+0x14/0x30 kasan_save_free_info+0x3a/0x60 __kasan_slab_free+0x3f/0x50 kfree+0x137/0x370 otx2_ptp_destroy+0x38/0x80 otx2_remove+0x10d/0x4c0 pci_device_remove+0xa6/0x1d0 device_release_driver_internal+0xf8/0x210 pci_stop_bus_device+0x105/0x150 pci_stop_and_remove_bus_device_locked+0x15/0x30 remove_store+0xcc/0xe0 kernfs_fop_write_iter+0x2c3/0x440 vfs_write+0x871/0xd70 ksys_write+0xee/0x1c0 do_syscall_64+0xac/0x280 entry_SYSCALL_64_after_hwframe+0x77/0x7f...Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensurethat the delayed work item is properly canceled before the otx2_ptp isdeallocated.This bug was initially identified through static analysis.

CVE-2025-39946 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:tls: make sure to abort the stream if headers are bogusNormally we wait for the socket to buffer up the whole recordbefore we service it. If the socket has a tiny buffer, however,we read out the data sooner, to prevent connection stalls.Make sure that we abort the connection when we find out latethat the record is actually invalid. Retrying the parsing isfine in itself but since we copy some more data each timebefore we parse we can overflow the allocated skb space.Constructing a scenario in which we're under pressure withoutenough data in the socket to parse the length upfront is quitehard. syzbot figured out a way to do this by serving us the headerin small OOB sends, and then filling in the recvbuf with a largenormal send.Make sure that tls_rx_msg_size() aborts strp, if we reachan invalid record there's really no way to recover.

The only checkwhich is performed by the PF_PACKET framework is to make sure thatskb->len fits the interface's MTU.Unfortunately, because the mcba_usb driver does not populate itsnet_device_ops->ndo_change_mtu(), it is possible for an attacker toconfigure an invalid MTU by doing, for example: $ ip link set can0 mtu 9999After doing so, the attacker could open a PF_PACKET socket using theETH_P_CANXL protocol: socket(PF_PACKET, SOCK_RAW, htons(ETH_P_CANXL))to inject a malicious CAN XL frames. For example: struct canxl_frame frame = { .flags = 0xff, .len = 2048, };The CAN drivers' xmit() function are calling can_dev_dropped_skb() tocheck that the skb is valid, unfortunately under above conditions, themalicious packet is able to go through can_dev_dropped_skb() checks: 1. the skb->protocol is set to ETH_P_CANXL which is valid (the function does not check the actual device capabilities). 2. the length is a valid CAN XL length.And so, mcba_usb_start_xmit() receives a CAN XL frame which it is notable to correctly handle and will thus misinterpret it as a CAN frame.This can result in a buffer overflow. The driver will consume cf->lenas-is with no further checks on these lines: usb_msg.dlc = cf->len; memcpy(usb_msg.data, cf->data, usb_msg.dlc);Here, cf->len corresponds to the flags field of the CAN XL frame.

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

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

This is already checked in pinmux_check_ops() so add a similarcheck in pinmux_func_name_to_selector() instead of passing the returnedpointer right down to strcmp() where the NULL can get dereferenced. Thisis normal operation when adding new pinfunctions.

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

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

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

CVE-2025-40052 Severity: Moderate CVSS3 score: 5.5

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:tty: n_gsm: Don't block input queue by waiting MSCCurrently gsm_queue() processes incoming frames and when openinga DLC channel it calls gsm_dlci_open() which calls gsm_modem_update().If basic mode is used it calls gsm_modem_upd_via_msc() and itcannot block the input queue by waiting the response to comeinto the same input queue.Instead allow sending Modem Status Command without waiting for remoteend to respond. Define a new function gsm_modem_send_initial_msc()for this purpose. As MSC is only valid for basic encoding, it doesnot do anything for advanced or when convergence layer type 2 is used.

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

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

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

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

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

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

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

CVE-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.

CVE-2023-53728 Severity: Moderate CVSS3 score: 5.3

Description: In the Linux kernel, the following vulnerability has been resolved:posix-timers: Ensure timer ID search-loop limit is validposix_timer_add() tries to allocate a posix timer ID by starting from thecached ID which was stored by the last successful allocation.This is done in a loop searching the ID space for a free slot one byone. The loop has to terminate when the search wrapped around to thestarting point.But that's racy vs. establishing the starting point. That is read outlockless, which leads to the following problem:CPU0 CPU1posix_timer_add() start = sig->posix_timer_id; lock(hash_lock); ... posix_timer_add() if (++sig->posix_timer_id < 0) start = sig->posix_timer_id; sig->posix_timer_id = 0;So CPU1 can observe a negative start value, i.e. -1, and the loop breaknever happens because the condition can never be true: if (sig->posix_timer_id == start) break;While this is unlikely to ever turn into an endless loop as the ID space ishuge (INT_MAX), the racy read of the start value caught the attention ofKCSAN and Dmitry unearthed that incorrectness.Rewrite it so that all id operations are under the hash lock.

Description: The attack vector is a potential Denial of Service (DoS). The vulnerability is caused by an insufficient check on the length of a decompressed domain name within a DNS packet.An attacker can craft a malicious DNS packet containing a highly compressed domain name. When the resolv library parses such a packet, the name decompression process consumes a large amount of CPU resources, as the library does not limit the resulting length of the name.This resource consumption can cause the application thread to become unresponsive, resulting in a Denial of Service condition.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix metadata_dst leak __bpf_redirect_neigh_v{4,6}Cilium has a BPF egress gateway feature which forces outgoing K8s Podtraffic to pass through dedicated egress gateways which then SNAT thetraffic in order to interact with stable IPs outside the cluster.The traffic is directed to the gateway via vxlan tunnel in collect mdmode. A recent BPF change utilized the bpf_redirect_neigh() helper toforward packets after the arrival and decap on vxlan, which turned outover time that the kmalloc-256 slab usage in kernel was ever-increasing.The issue was that vxlan allocates the metadata_dst object and attachesit through a fake dst entry to the skb. The latter was never releasedthough given bpf_redirect_neigh() was merely setting the new dst entryvia skb_dst_set() without dropping an existing one first.

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

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

CVE-2025-61664 Severity: Moderate CVSS3 score: 4.9

Description: A vulnerability in the GRUB2 bootloader has been identified in the normal module. This flaw, a memory Use After Free issue, occurs because the normal_exit command is not properly unregistered when its related module is unloaded. An attacker can exploit this condition by invoking the command after the module has been removed, causing the system to improperly access a previously freed memory location. This leads to a system crash or possible impacts in data confidentiality and integrity.

CVE-2025-7039 Severity: Moderate CVSS3 score: 4.9

Description: A flaw was found in glib. An integer overflow during temporary file creation leads to an out-of-bounds memory access, allowing an attacker to potentially perform path traversal or access private temporary file content by creating symbolic links. This vulnerability allows a local attacker to manipulate file paths and access unauthorized data. The core issue stems from insufficient validation of file path lengths during temporary file operations.

CVE-2025-61661 Severity: Moderate CVSS3 score: 4.8

Description: A vulnerability has been identified in the GRUB (Grand Unified Bootloader) component. This flaw occurs because the bootloader mishandles string conversion when reading information from a USB device, allowing an attacker to exploit inconsistent length values. A local attacker can connect a maliciously configured USB device during the boot sequence to trigger this issue. A successful exploitation may lead GRUB to crash, leading to a Denial of Service. Data corruption may be also possible, although given the complexity of the exploit the impact is most likely limited.

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5e: Check for NOT_READY flag state after lockingCurrently the check for NOT_READY flag is performed before obtaining thenecessary lock. This opens a possibility for race condition when the flowis concurrently removed from unready_flows list by the workqueue task,which causes a double-removal from the list and a crash[0]. Fix the issueby moving the flag check inside the section protected byuplink_priv->unready_flows_lock mutex.[0]:[44376.389654] general protection fault, probably for non-canonical address 0xdead000000000108: 0000 [#1] SMP[44376.391665] CPU: 7 PID: 59123 Comm: tc Not tainted 6.4.0-rc4+ #1[44376.392984] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014[44376.395342] RIP: 0010:mlx5e_tc_del_fdb_flow+0xb3/0x340 [mlx5_core][44376.396857] Code: 00 48 8b b8 68 ce 02 00 e8 8a 4d 02 00 4c 8d a8 a8 01 00 00 4c 89 ef e8 8b 79 88 e1 48 8b 83 98 06 00 00 48 8b 93 90 06 00 00 <48> 89 42 08 48 89 10 48 b8 00 01 00 00 00 00 ad de 48 89 83 90 06[44376.399167] RSP: 0018:ffff88812cc97570 EFLAGS: 00010246[44376.399680] RAX: dead000000000122 RBX: ffff8881088e3800 RCX: ffff8881881bac00[44376.400337] RDX: dead000000000100 RSI: ffff88812cc97500 RDI: ffff8881242f71b0[44376.401001] RBP: ffff88811cbb0940 R08: 0000000000000400 R09: 0000000000000001[44376.401663] R10: 0000000000000001 R11: 0000000000000000 R12: ffff88812c944000[44376.402342] R13: ffff8881242f71a8 R14: ffff8881222b4000 R15: 0000000000000000[44376.402999] FS: 00007f0451104800(0000) GS:ffff88852cb80000(0000) knlGS:0000000000000000[44376.403787] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[44376.404343] CR2: 0000000000489108 CR3: 0000000123a79003 CR4: 0000000000370ea0[44376.405004] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[44376.405665] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[44376.406339] Call Trace:[44376.406651] [44376.406939] ? die_addr+0x33/0x90[44376.407311] ? exc_general_protection+0x192/0x390[44376.407795] ? asm_exc_general_protection+0x22/0x30[44376.408292] ? mlx5e_tc_del_fdb_flow+0xb3/0x340 [mlx5_core][44376.408876] __mlx5e_tc_del_fdb_peer_flow+0xbc/0xe0 [mlx5_core][44376.409482] mlx5e_tc_del_flow+0x42/0x210 [mlx5_core][44376.410055] mlx5e_flow_put+0x25/0x50 [mlx5_core][44376.410529] mlx5e_delete_flower+0x24b/0x350 [mlx5_core][44376.411043] tc_setup_cb_reoffload+0x22/0x80[44376.411462] fl_reoffload+0x261/0x2f0 [cls_flower][44376.411907] ? mlx5e_rep_indr_setup_ft_cb+0x160/0x160 [mlx5_core][44376.412481] ? mlx5e_rep_indr_setup_ft_cb+0x160/0x160 [mlx5_core][44376.413044] tcf_block_playback_offloads+0x76/0x170[44376.413497] tcf_block_unbind+0x7b/0xd0[44376.413881] tcf_block_setup+0x17d/0x1c0[44376.414269] tcf_block_offload_cmd.isra.0+0xf1/0x130[44376.414725] tcf_block_offload_unbind+0x43/0x70[44376.415153] __tcf_block_put+0x82/0x150[44376.415532] ingress_destroy+0x22/0x30 [sch_ingress][44376.415986] qdisc_destroy+0x3b/0xd0[44376.416343] qdisc_graft+0x4d0/0x620[44376.416706] tc_get_qdisc+0x1c9/0x3b0[44376.417074] rtnetlink_rcv_msg+0x29c/0x390[44376.419978] ? rep_movs_alternative+0x3a/0xa0[44376.420399] ? rtnl_calcit.isra.0+0x120/0x120[44376.420813] netlink_rcv_skb+0x54/0x100[44376.421192] netlink_unicast+0x1f6/0x2c0[44376.421573] netlink_sendmsg+0x232/0x4a0[44376.421980] sock_sendmsg+0x38/0x60[44376.422328] ____sys_sendmsg+0x1d0/0x1e0[44376.422709] ? copy_msghdr_from_user+0x6d/0xa0[44376.423127] ___sys_sendmsg+0x80/0xc0[44376.423495] ? ___sys_recvmsg+0x8b/0xc0[44376.423869] __sys_sendmsg+0x51/0x90[44376.424226] do_syscall_64+0x3d/0x90[44376.424587] entry_SYSCALL_64_after_hwframe+0x46/0xb0[44376.425046] RIP: 0033:0x7f045134f887[44376.425403] Code: 0a 00 f7 d8 64 89 02 48 c7 c0 ff ff ff ff eb b9 0f 1f 00 f3 0f 1e fa 64 8b 04 25 18 00 00 00 85 c0 75 10 b8 2e 00---truncated---

The array is filled in mwifiex_update_chan_statistics()and then the user can query the data in mwifiex_cfg80211_dump_survey().There are two potential issues here. What if the user callsmwifiex_cfg80211_dump_survey() before the data has been filled in.Also the mwifiex_update_chan_statistics() function doesn't necessarilyinitialize the whole array. Since the array was not initialized atthe start that could result in an information leak.Also this array is pretty small. It's a maximum of 900 bytes so it'smore appropriate to use kcalloc() instead vmalloc().

This can lead to use-after-free ifthe memory is released before splice_to_pipe() completes.Use folio_alloc() instead, ensuring DMBs are page-backed and safe forget_page().WARNING: CPU: 18 PID: 12152 at ./include/linux/mm.h:1330 smc_rx_splice+0xaf8/0xe20 [smc]CPU: 18 UID: 0 PID: 12152 Comm: smcapp Kdump: loaded Not tainted 6.17.0-rc3-11705-g9cf4672ecfee #10 NONEHardware name: IBM 3931 A01 704 (z/VM 7.4.0)Krnl PSW : 0704e00180000000 000793161032696c (smc_rx_splice+0xafc/0xe20 [smc]) R:0 T:1 IO:1 EX:1 Key:0 M:1 W:0 P:0 AS:3 CC:2 PM:0 RI:0 EA:3Krnl GPRS: 0000000000000000 001cee80007d3001 00077400000000f8 0000000000000005 0000000000000001 001cee80007d3006 0007740000001000 001c000000000000 000000009b0c99e0 0000000000001000 001c0000000000f8 001c000000000000 000003ffcc6f7c88 0007740003e98000 0007931600000005 000792969b2ff7b8Krnl Code: 0007931610326960: af000000 mc 0,0 0007931610326964: a7f4ff43 brc 15,00079316103267ea #0007931610326968: af000000 mc 0,0 >000793161032696c: a7f4ff3f brc 15,00079316103267ea 0007931610326970: e320f1000004 lg %r2,256(%r15) 0007931610326976: c0e53fd1b5f5 brasl %r14,000793168fd5d560 000793161032697c: a7f4fbb5 brc 15,00079316103260e6 0007931610326980: b904002b lgr %r2,%r11Call Trace: smc_rx_splice+0xafc/0xe20 [smc] smc_rx_splice+0x756/0xe20 [smc]) smc_rx_recvmsg+0xa74/0xe00 [smc] smc_splice_read+0x1ce/0x3b0 [smc] sock_splice_read+0xa2/0xf0 do_splice_read+0x198/0x240 splice_file_to_pipe+0x7e/0x110 do_splice+0x59e/0xde0 __do_splice+0x11a/0x2d0 __s390x_sys_splice+0x140/0x1f0 __do_syscall+0x122/0x280 system_call+0x6e/0x90Last Breaking-Event-Address:smc_rx_splice+0x960/0xe20 [smc]---[ end trace 0000000000000000 ]---

Description: In the Linux kernel, the following vulnerability has been resolved:clk: mediatek: mt8183: Add back SSPM related clocksThis reverts commit 860690a93ef23b567f781c1b631623e27190f101.On the MT8183, the SSPM related clocks were removed claiming a lack ofusage. This however causes some issues when the driver was converted tothe new simple-probe mechanism. This mechanism allocates enough spacefor all the clocks defined in the clock driver, not the highest indexin the DT binding. This leads to out-of-bound writes if their are holesin the DT binding or the driver (due to deprecated or unimplementedclocks). These errors can go unnoticed and cause memory corruption,leading to crashes in unrelated areas, or nothing at all. KASAN willdetect them.Add the SSPM related clocks back to the MT8183 clock driver to fullyimplement the DT binding. The SSPM clocks are for the power managementco-processor, and should never be turned off. They are marked as such.

CVE-2023-53523 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:can: gs_usb: fix time stamp counter initializationIf the gs_usb device driver is unloaded (or unbound) before theinterface is shut down, the USB stack first calls the structusb_driver::disconnect and then the struct net_device_ops::ndo_stopcallback.In gs_usb_disconnect() all pending bulk URBs are killed, i.e. no moreRX'ed CAN frames are send from the USB device to the host. Later ings_can_close() a reset control message is send to each CAN channel toremove the controller from the CAN bus. In this race window the USBdevice can still receive CAN frames from the bus and internally queuethem to be send to the host.At least in the current version of the candlelight firmware, the queueof received CAN frames is not emptied during the reset command. Afterloading (or binding) the gs_usb driver, new URBs are submitted duringthe struct net_device_ops::ndo_open callback and the candlelightfirmware starts sending its already queued CAN frames to the host.However, this scenario was not considered when implementing thehardware timestamp function. The cycle counter/time counterinfrastructure is set up (gs_usb_timestamp_init()) after the USBs aresubmitted, resulting in a NULL pointer dereference iftimecounter_cyc2time() (via the call chain:gs_usb_receive_bulk_callback() -> gs_usb_set_timestamp() ->gs_usb_skb_set_timestamp()) is called too early.Move the gs_usb_timestamp_init() function before the URBs aresubmitted to fix this problem.For a comprehensive solution, we need to consider gs_usb devices withmore than 1 channel. The cycle counter/time counter infrastructure issetup per channel, but the RX URBs are per device. Once gs_can_open()of _a_ channel has been called, and URBs have been submitted, thegs_usb_receive_bulk_callback() can be called for _all_ availablechannels, even for channels that are not running, yet. As cyclecounter/time counter has not set up, this will again lead to a NULLpointer dereference.Convert the cycle counter/time counter from a "per channel" to a "perdevice" functionality. Also set it up, before submitting any URBs tothe device.Further in gs_usb_receive_bulk_callback(), don't process any URBs fornot started CAN channels, only resubmit the URB.

Then when reducingthe ringbuffer, and if some reduced pages exist dirty 'entries' data, theywill be added into 'cpu_buffer->overrun' (see rb_remove_pages()), whichcause wrong 'overrun' count and eventually cause the deadloop issue.To fix it, we need to clear every pages in rb_reset_cpu().

CVE-2023-53699 Severity: Moderate CVSS3 score: 4.4

Description: In the Linux kernel, the following vulnerability has been resolved:riscv: move memblock_allow_resize() after linear mapping is readyThe initial memblock metadata is accessed from kernel image mapping. Theregions arrays need to "reallocated" from memblock and accessed throughlinear mapping to cover more memblock regions. So the resizing shouldnot be allowed until linear mapping is ready. Note that there arememblock allocations when building linear mapping.This patch is similar to 24cc61d8cb5a ("arm64: memblock: don't permitmemblock resizing until linear mapping is up").In following log, many memblock regions are reserved beforecreate_linear_mapping_page_table(). And then it triggered reallocationof memblock.reserved.regions and memcpy the old array in kernel imagemapping to the new array in linear mapping which caused a page fault.[ 0.000000] memblock_reserve: [0x00000000bf01f000-0x00000000bf01ffff] early_init_fdt_scan_reserved_mem+0x28c/0x2c6[ 0.000000] memblock_reserve: [0x00000000bf021000-0x00000000bf021fff] early_init_fdt_scan_reserved_mem+0x28c/0x2c6[ 0.000000] memblock_reserve: [0x00000000bf023000-0x00000000bf023fff] early_init_fdt_scan_reserved_mem+0x28c/0x2c6[ 0.000000] memblock_reserve: [0x00000000bf025000-0x00000000bf025fff] early_init_fdt_scan_reserved_mem+0x28c/0x2c6[ 0.000000] memblock_reserve: [0x00000000bf027000-0x00000000bf027fff] early_init_fdt_scan_reserved_mem+0x28c/0x2c6[ 0.000000] memblock_reserve: [0x00000000bf029000-0x00000000bf029fff] early_init_fdt_scan_reserved_mem+0x28c/0x2c6[ 0.000000] memblock_reserve: [0x00000000bf02b000-0x00000000bf02bfff] early_init_fdt_scan_reserved_mem+0x28c/0x2c6[ 0.000000] memblock_reserve: [0x00000000bf02d000-0x00000000bf02dfff] early_init_fdt_scan_reserved_mem+0x28c/0x2c6[ 0.000000] memblock_reserve: [0x00000000bf02f000-0x00000000bf02ffff] early_init_fdt_scan_reserved_mem+0x28c/0x2c6[ 0.000000] memblock_reserve: [0x00000000bf030000-0x00000000bf030fff] early_init_fdt_scan_reserved_mem+0x28c/0x2c6[ 0.000000] OF: reserved mem: 0x0000000080000000..0x000000008007ffff (512 KiB) map non-reusable mmode_resv0@80000000[ 0.000000] memblock_reserve: [0x00000000bf000000-0x00000000bf001fed] paging_init+0x19a/0x5ae[ 0.000000] memblock_phys_alloc_range: 4096 bytes align=0x1000 from=0x0000000000000000 max_addr=0x0000000000000000 alloc_pmd_fixmap+0x14/0x1c[ 0.000000] memblock_reserve: [0x000000017ffff000-0x000000017fffffff] memblock_alloc_range_nid+0xb8/0x128[ 0.000000] memblock: reserved is doubled to 256 at [0x000000017fffd000-0x000000017fffe7ff][ 0.000000] Unable to handle kernel paging request at virtual address ff600000ffffd000[ 0.000000] Oops [#1][ 0.000000] Modules linked in:[ 0.000000] CPU: 0 PID: 0 Comm: swapper Not tainted 6.4.0-rc1-00011-g99a670b2069c #66[ 0.000000] Hardware name: riscv-virtio,qemu (DT)[ 0.000000] epc : __memcpy+0x60/0xf8[ 0.000000] ra : memblock_double_array+0x192/0x248[ 0.000000] epc : ffffffff8081d214 ra : ffffffff80a3dfc0 sp : ffffffff81403bd0[ 0.000000] gp : ffffffff814fbb38 tp : ffffffff8140dac0 t0 : 0000000001600000[ 0.000000] t1 : 0000000000000000 t2 : 000000008f001000 s0 : ffffffff81403c60[ 0.000000] s1 : ffffffff80c0bc98 a0 : ff600000ffffd000 a1 : ffffffff80c0bcd8[ 0.000000] a2 : 0000000000000c00 a3 : ffffffff80c0c8d8 a4 : 0000000080000000[ 0.000000] a5 : 0000000000080000 a6 : 0000000000000000 a7 : 0000000080200000[ 0.000000] s2 : ff600000ffffd000 s3 : 0000000000002000 s4 : 0000000000000c00[ 0.000000] s5 : ffffffff80c0bc60 s6 : ffffffff80c0bcc8 s7 : 0000000000000000[ 0.000000] s8 : ffffffff814fd0a8 s9 : 000000017fffe7ff s10: 0000000000000000[ 0.000000] s11: 0000000000001000 t3 : 0000000000001000 t4 : 0000000000000000[ 0.000000] t5 : 000000008f003000 t6 : ff600000ffffd000[ 0.000000] status: 0000000200000100 badaddr: ff600000ffffd000 cause: 000000000000000f[ 0.000000] [

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

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

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

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

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:media: uvcvideo: Mark invalid entities with id UVC_INVALID_ENTITY_IDPer UVC 1.1+ specification 3.7.2, units and terminals must have a non-zerounique ID.```Each Unit and Terminal within the video function is assigned a uniqueidentification number, the Unit ID (UID) or Terminal ID (TID), contained inthe bUnitID or bTerminalID field of the descriptor. The value 0x00 isreserved for undefined ID,```If we add a new entity with id 0 or a duplicated ID, it will be markedas UVC_INVALID_ENTITY_ID.In a previous attempt commit 3dd075fe8ebb ("media: uvcvideo: Requireentities to have a non-zero unique ID"), we ignored all the invalid units,this broke a lot of non-compatible cameras. Hopefully we are more luckythis time.This also prevents some syzkaller reproducers from triggering warnings dueto a chain of entities referring to themselves. In one particular case, anOutput Unit is connected to an Input Unit, both with the same ID of 1. Butwhen looking up for the source ID of the Output Unit, that same entity isfound instead of the input entity, which leads to such warnings.In another case, a backward chain was considered finished as the source IDwas 0.

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

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

CVE-2023-53698 Severity: Low CVSS3 score: 2.5

Description: In the Linux kernel, the following vulnerability has been resolved:xsk: fix refcount underflow in error pathFix a refcount underflow problem reported by syzbot that can happenwhen a system is running out of memory. If xp_alloc_tx_descs() fails,and it can only fail due to not having enough memory, then the errorpath is triggered. In this error path, the refcount of the pool isdecremented as it has incremented before. However, the reference tothe pool in the socket was not nulled. This means that when the socketis closed later, the socket teardown logic will think that there is apool attached to the socket and try to decrease the refcount again,leading to a refcount underflow.I chose this fix as it involved adding just a single line. Anotheroption would have been to move xp_get_pool() and the assignment ofxs->pool to after the if-statement and using xs_umem->pool instead ofxs->pool in the whole if-statement resulting in somewhat simpler code,but this would have led to much more churn in the code base perhapsmaking it harder to backport.

CVE-2023-53585 Severity: Low CVSS3 score: 2.3

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: reject unhashed sockets in bpf_sk_assignThe semantics for bpf_sk_assign are as follows: sk = some_lookup_func() bpf_sk_assign(skb, sk) bpf_sk_release(sk)That is, the sk is not consumed by bpf_sk_assign. The functiontherefore needs to make sure that sk lives long enough to beconsumed from __inet_lookup_skb. The path through the stack for aTCPv4 packet is roughly: netif_receive_skb_core: takes RCU read lock __netif_receive_skb_core: sch_handle_ingress: tcf_classify: bpf_sk_assign() deliver_ptype_list_skb: deliver_skb: ip_packet_type->func == ip_rcv: ip_rcv_core: ip_rcv_finish_core: dst_input: ip_local_deliver: ip_local_deliver_finish: ip_protocol_deliver_rcu: tcp_v4_rcv: __inet_lookup_skb: skb_steal_sockThe existing helper takes advantage of the fact that everythinghappens in the same RCU critical section: for sockets withSOCK_RCU_FREE set bpf_sk_assign never takes a reference.skb_steal_sock then checks SOCK_RCU_FREE again and does sock_putif necessary.This approach assumes that SOCK_RCU_FREE is never set on a skbetween bpf_sk_assign and skb_steal_sock, but this invariant isviolated by unhashed UDP sockets. A new UDP socket is createdin TCP_CLOSE state but without SOCK_RCU_FREE set. That flag is onlyadded in udp_lib_get_port() which happens when a socket is bound.When bpf_sk_assign was added it wasn't possible to access unhashedUDP sockets from BPF, so this wasn't a problem. This changedin commit 0c48eefae712 ("sock_map: Lift socket state restrictionfor datagram sockets"), but the helper wasn't adjusted accordingly.The following sequence of events will therefore lead to a refcountleak:1. Add socket(AF_INET, SOCK_DGRAM) to a sockmap.2. Pull socket out of sockmap and bpf_sk_assign it. Since SOCK_RCU_FREE is not set we increment the refcount.3. bind() or connect() the socket, setting SOCK_RCU_FREE.4. skb_steal_sock will now set refcounted = false due to SOCK_RCU_FREE.5. tcp_v4_rcv() skips sock_put().Fix the problem by rejecting unhashed sockets in bpf_sk_assign().This matches the behaviour of __inet_lookup_skb which is ultimatelythe goal of bpf_sk_assign().

If no task can bebalanced to dst_cpu we'll try to balance the task to the new_dst_cpuinstead. In this case when the migration disabled task is not on CPU itonly allows to run on its current CPU, load balance will select itscurrent CPU as new_dst_cpu and later triggers the warning above.The new_dst_cpu is chosen from the env->dst_grpmask. Currently itcontains CPUs in sched_group_span() and if we have overlapped groups it'spossible to run into this case. This patch makes env->dst_grpmask ofgroup_balance_mask() which exclude any CPUs from the busiest group andsolve the issue. For balancing in a domain with no overlapped groupsthe behaviour keeps same as before.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: add handling for RAID1C23/DUP to btrfs_reduce_alloc_profileCallers of `btrfs_reduce_alloc_profile` expect it to return exactlyone allocation profile flag, and failing to do so may ultimatelyresult in a WARN_ON and remount-ro when allocating new blocks, likethe below transaction abort on 6.1.`btrfs_reduce_alloc_profile` has two ways of determining the profile,first it checks if a conversion balance is currently running anduses the profile we're converting to. If no balance is currentlyrunning, it returns the max-redundancy profile which at least oneblock in the selected block group has.This works by simply checking each known allocation profile bit inredundancy order. However, `btrfs_reduce_alloc_profile` has not beenupdated as new flags have been added - first with the `DUP` profileand later with the RAID1C34 profiles.Because of the way it checks, if we have blocks with differentprofiles and at least one is known, that profile will be selected.However, if none are known we may return a flag set with multipleallocation profiles set.This is currently only possible when a balance from one of the threeunhandled profiles to another of the unhandled profiles is canceledafter allocating at least one block using the new profile.In that case, a transaction abort like the below will occur and thefilesystem will need to be mounted with -o skip_balance to get itmounted rw again (but the balance cannot be resumed without asimilar abort).

CVE-2023-53491 Severity: Moderate CVSS3 score: 0.0

Description: In the Linux kernel, the following vulnerability has been resolved:start_kernel: Add __no_stack_protector function attributeBack during the discussion ofcommit a9a3ed1eff36 ("x86: Fix early boot crash on gcc-10, third try")we discussed the need for a function attribute to control the omissionof stack protectors on a per-function basis; at the time Clang hadsupport for no_stack_protector but GCC did not. This was fixed ingcc-11. Now that the function attribute is available, let's start usingit.Callers of boot_init_stack_canary need to use this function attributeunless they're compiled with -fno-stack-protector, otherwise the canarystored in the stack slot of the caller will differ upon the call toboot_init_stack_canary. This will lead to a call to __stack_chk_fail()then panic.

Description: In the Linux kernel, the following vulnerability has been resolved:perf: RISC-V: Remove PERF_HES_STOPPED flag checking in riscv_pmu_start()Since commit 096b52fd2bb4 ("perf: RISC-V: throttle perf events") theperf_sample_event_took() function was added to report time spent inoverflow interrupts. If the interrupt takes too long, the perf frameworkwill lower the sysctl_perf_event_sample_rate and max_samples_per_tick.When hwc->interrupts is larger than max_samples_per_tick, thehwc->interrupts will be set to MAX_INTERRUPTS, and events will bethrottled within the __perf_event_account_interrupt() function.However, the RISC-V PMU driver doesn't call riscv_pmu_stop() to update thePERF_HES_STOPPED flag after perf_event_overflow() in pmu_sbi_ovf_handler()function to avoid throttling. When the perf framework unthrottled the eventin the timer interrupt handler, it triggers riscv_pmu_start() functionand causes a WARN_ON_ONCE() warning, as shown below: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 240 at drivers/perf/riscv_pmu.c:184 riscv_pmu_start+0x7c/0x8e Modules linked in: CPU: 0 PID: 240 Comm: ls Not tainted 6.4-rc4-g19d0788e9ef2 #1 Hardware name: SiFive (DT) epc : riscv_pmu_start+0x7c/0x8e ra : riscv_pmu_start+0x28/0x8e epc : ffffffff80aef864 ra : ffffffff80aef810 sp : ffff8f80004db6f0 gp : ffffffff81c83750 tp : ffffaf80069f9bc0 t0 : ffff8f80004db6c0 t1 : 0000000000000000 t2 : 000000000000001f s0 : ffff8f80004db720 s1 : ffffaf8008ca1068 a0 : 0000ffffffffffff a1 : 0000000000000000 a2 : 0000000000000001 a3 : 0000000000000870 a4 : 0000000000000000 a5 : 0000000000000000 a6 : 0000000000000840 a7 : 0000000000000030 s2 : 0000000000000000 s3 : ffffaf8005165800 s4 : ffffaf800424da00 s5 : ffffffffffffffff s6 : ffffffff81cc7590 s7 : 0000000000000000 s8 : 0000000000000006 s9 : 0000000000000001 s10: ffffaf807efbc340 s11: ffffaf807efbbf00 t3 : ffffaf8006a16028 t4 : 00000000dbfbb796 t5 : 0000000700000000 t6 : ffffaf8005269870 status: 0000000200000100 badaddr: 0000000000000000 cause: 0000000000000003 [] riscv_pmu_start+0x7c/0x8e [] perf_adjust_freq_unthr_context+0x15e/0x174 [] perf_event_task_tick+0x88/0x9c [] scheduler_tick+0xfe/0x27c [] update_process_times+0x9a/0xba [] tick_sched_handle+0x32/0x66 [] tick_sched_timer+0x64/0xb0 [] __hrtimer_run_queues+0x156/0x2f4 [] hrtimer_interrupt+0xe2/0x1fe [] riscv_timer_interrupt+0x38/0x42 [] handle_percpu_devid_irq+0x90/0x1d2 [] generic_handle_domain_irq+0x28/0x36After referring other PMU drivers like Arm, Loongarch, Csky, and Mips,they don't call *_pmu_stop() to update with PERF_HES_STOPPED flagafter perf_event_overflow() function nor do they add PERF_HES_STOPPEDflag checking in *_pmu_start() which don't cause this warning.Thus, it's recommended to remove this unnecessary check inriscv_pmu_start() function to prevent this warning.

CVE-2025-39801 Severity: Moderate CVSS3 score: 0.0

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

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

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