| CVE-2026-74403 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Check for page allocation failure correctly in TIO Sashiko notes: > if __snp_alloc_firmware_pages() returns NULL under memory pressure, is it > safe to pass it directly to page_address()? > > On architectures without HASHED_PAGE_VIRTUAL, page_address(NULL) might > compute a deterministic but invalid, non-zero virtual address. The > subsequent if (tio_status) check would then evaluate to true, and > sev_tsm_init_locked() would dereference the invalid pointer. Indeed, page_address(NULL) will return non-NULL garbage here. Fix this by checking the page allocation itself for NULL, not the resulting virtual address. | ||||

| In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix UAF in rxgk_issue_challenge() Fix rxgk_issue_challenge() to free the page containing the challenge content after invoking the tracepoint as the whdr passed to the tracepoint points into the page just freed. | ||||
| CVE-2026-74434 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: rxrpc: Don't move a peeked OOB message onto the pending queue rxrpc_recvmsg_oob() takes a received oob message off recvmsg_oobq and, if a response is needed, moves it onto the pending_oobq tree. However, only the unlink from recvmsg_oobq is guarded by MSG_PEEK; the move onto pending_oobq always runs. As a result, reading a challenge with MSG_PEEK leaves the skb on recvmsg_oobq while also adding it to pending_oobq. Since struct sk_buff's rbnode shares storage with its next and prev pointers, rb_insert_color() overwrites the list linkage, and the skb, which holds a single reference, becomes reachable from both queues at once. When the socket is closed both queues are drained in turn. While draining recvmsg_oobq, __skb_unlink() follows the next and prev pointers that rbnode has overwritten and writes to a bad address. Also, as the skb holds a single reference but is freed from each queue, both the skb and the connection reference it holds are released twice. This leads to memory corruption and to a use-after-free caused by the connection refcount underflow. MSG_PEEK does not consume the message from the queue, so only unlink it from recvmsg_oobq and then move it onto pending_oobq or free it when the message is actually consumed. | ||||
| CVE-2023-6931 | 3 Debian, Linux, Redhat | 6 Debian Linux, Linux Kernel, Enterprise Linux and 3 more | 2026-08-17 | 7.8 High |
| A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation. A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group(). We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b. | ||||

| CVE-2026-74311 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: virtio: rtc: tear down old virtqueues before restore virtio_device_restore() resets the device and restores the negotiated features before calling ->restore(). viortc_freeze() intentionally leaves the existing virtqueues in place so the alarm queue can still wake the system, but viortc_restore() immediately calls viortc_init_vqs() without first deleting those old queues. If virtqueue reinitialization fails on virtio-pci, the transport error path can run vp_del_vqs() against a newly allocated vp_dev->vqs array while vdev->vqs still contains the old virtqueues. vp_del_vqs() then looks up queue state through the new array and can dereference a NULL info pointer in vp_del_vq(), crashing the guest kernel during restore. This can also happen during a non-faulty reinitialization, when one of the vp_find_vqs_msix() attempts is unsuccessful before a later attempt would succeed. Delete the stale virtqueues before rebuilding them. If restore fails before virtio_device_ready(), reuse the remove path to stop the device. Once the device is ready, return errors directly instead of deleting the virtqueues again. | ||||

| CVE-2026-74364 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Reject exclusive maps as inner maps in map-in-map An exclusive map (created with excl_prog_hash) is bound to a single program by hash: check_map_prog_compatibility() refuses to load any program whose digest does not match map->excl_prog_sha. That check only runs for maps a program references directly, i.e. its used_maps. A map reached at runtime through a map-of-maps is never in used_maps, and bpf_map_meta_equal() does not consider excl_prog_sha, so an exclusive map can be inserted into a non-exclusive outer map and then looked up and mutated by an unrelated program, bypassing the exclusivity guarantee. For the signed loader this defeats the metadata map exclusivity check added in the signed loader: the cached map->sha[] is validated against the signed hash while another program on a hostile host rewrites the frozen map's contents through the outer map. | ||||
| CVE-2026-74425 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: afs: handle CB.InitCallBackState3 requests without a server record The cache manager callback path now attaches the server record to an incoming call through the rxrpc peer's app data. That association is not guaranteed to exist for every callback request, and most callback handlers already tolerate that case. Make CB.InitCallBackState3 follow the same pattern by checking whether a server record was attached before using it. If the peer is not mapped to a server record, trace the request and ignore it, matching the existing behaviour for other unmatched callback requests. This keeps the callback handler consistent with the rest of the cache manager service and avoids depending on peer state that may not be available for a given request. | ||||
| CVE-2026-47487 | 2 Linux, Nvidia | 2 Linux Kernel, Triton Inference Server | 2026-08-17 | 4.4 Medium |
| NVIDIA Triton Inference Server for Linux contains a vulnerability where a user could cause files outside the model repository to be read, written to, or modified by providing a path in the model name to the Triton MLflow plugin. A successful exploit of this vulnerability might lead to denial of service and information disclosure. | ||||
| CVE-2026-74357 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix KASAN slab-out-of-bounds in amdgpu_coredump ring dump The ring content dump in amdgpu_coredump() uses two separate loops over adev->rings[]: the first counts rings with unsignalled fences to size the allocation, and the second copies ring data into the allocated buffers. Both loops use the same condition to skip rings: atomic_read(&ring->fence_drv.last_seq) == ring->fence_drv.sync_seq Because last_seq is an atomic that is updated concurrently by the fence signalling path, additional rings may appear unsignalled in the second loop that were signalled during the first. When this happens, idx exceeds the allocated ring_count and the store to coredump->rings[idx] writes past the end of the kcalloc-ed buffer. This was found during IGT stressful test amd_queue_reset which triggers random GPU resets. The OVERSIZE subtest (CMD_STREAM_EXEC_INVALID_PACKET_LENGTH_OVERSIZE on GFX ring) provokes a ring timeout and subsequent coredump, which hits the race between the counting and copying loops. The failure is non-deterministic and depends on fence signalling timing during the reset. KASAN log: BUG: KASAN: slab-out-of-bounds in amdgpu_coredump+0x1274/0x12f0 [amdgpu] Write of size 4 at addr ffff888106154258 by task kworker/u128:5/23625 CPU: 16 UID: 0 PID: 23625 Comm: kworker/u128:5 Not tainted 6.19.0+ #35 Workqueue: amdgpu-reset-dev drm_sched_job_timedout [gpu_sched] Call Trace: <TASK> dump_stack_lvl+0xa5/0x110 print_report+0xd1/0x660 kasan_report+0xf3/0x130 __asan_report_store4_noabort+0x17/0x30 amdgpu_coredump+0x1274/0x12f0 [amdgpu] amdgpu_job_timedout+0xef0/0x16c0 [amdgpu] drm_sched_job_timedout+0x194/0x5c0 [gpu_sched] process_one_work+0x84b/0x1990 worker_thread+0x6b8/0x11b0 </TASK> Allocated by task 23625: kasan_save_stack+0x39/0x70 __kasan_kmalloc+0xc3/0xd0 __kmalloc_noprof+0x2ec/0x910 amdgpu_coredump+0x5c5/0x12f0 [amdgpu] amdgpu_job_timedout+0xef0/0x16c0 [amdgpu] The buggy address belongs to the object at ffff888106154200 which belongs to the cache kmalloc-rnd-09-96 of size 96 The buggy address is located 16 bytes to the right of allocated 72-byte region [ffff888106154200, ffff888106154248) 72 bytes = 3 * sizeof(struct amdgpu_coredump_ring), so ring_count was 3 but idx reached 3+, writing ring_index (at struct offset 16) 16 bytes past the allocation. Fix by adding an idx < ring_count guard to the copy loop so it cannot exceed the allocated count even when the fence state changes between the two passes. | ||||
| CVE-2026-74452 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/panthor: reject firmware sections with oversized data In panthor_fw_load_section_entry(), the data size to copy is calculated without validating it against the allocated section_size: section->data.size = hdr.data.end - hdr.data.start; If a crafted firmware sets data.size larger than the allocated memory, this could cause a heap buffer overflow in panthor_fw_init_section_mem() memcpy(section->mem->kmap, section->data.buf, section->data.size); Additionally, if the section->data.size exceeds the BO size, could this memset underflow the size calculation, leading to a massive out-of-bounds zeroing of kernel memory? memset(section->mem->kmap + section->data.size, 0, panthor_kernel_bo_size(section->mem) - section->data.size); Reject section entries whose initial data is larger than the section size. | ||||
| CVE-2026-74451 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/panthor: validate firmware interface structure sizes iface_fw_to_cpu_addr() only checks that the firmware-provided MCU virtual address points inside the shared section. The returned pointer is later used as a full firmware interface structure, so accepting an address near the end of the shared section can still lead to out-of-bounds accesses. Pass the expected object size to iface_fw_to_cpu_addr() and reject ranges that do not fit entirely in the shared section. | ||||

| In the Linux kernel, the following vulnerability has been resolved: ntfs: harden runlist realloc size calculations Add a shared helper to safely convert runlist element counts to byte sizes using overflow checks, and use it in both ntfs_rl_realloc() and ntfs_rl_realloc_nofail(). | ||||
| CVE-2026-74429 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix the reception of a reply packet before data transmission Fix rxrpc_receiving_reply() to handle the reception of an apparent reply DATA packet before rxrpc has had a chance to send any request DATA packets on a client call by checking to see if the call has been exposed yet by sending the first packet. Without this, rxrpc_rotate_tx_window() might oops. Also fix rxrpc_rotate_tx_window() to handle the Tx queue being empty by changing the do...while loop into a while loop, just in case a call is abnormally terminated by an early reply before the last request packet is transmitted. | ||||
| CVE-2026-74430 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix ACKALL packet handling rxrpc_input_ackall() accepts ACKALL packets without checking whether the call is in a state that can legitimately have outstanding transmit buffers. A forged ACKALL can therefore reach a new service call in RXRPC_CALL_SERVER_RECV_REQUEST before any reply packets have been queued. In that state call->tx_top is zero and call->tx_queue is NULL, so rxrpc_rotate_tx_window() dereferences a NULL txqueue and triggers a null-pointer dereference. Fix the handling of ACKALL packets by the following means: (1) Add two new call states: RXRPC_CALL_CLIENT_PRE_SEND which indicates that the client call is connected, but nothing has been transmitted as yet; and RXRPC_CALL_CLIENT_AWAIT_ACK, which indicates that everything has been transmitted at least once, but we're now waiting for the stuff remaining in the Tx buffer to be ACK'd (retransmissions may still happen). The RXRPC_CALL_CLIENT_PRE_SEND state is set when the call is assigned a channel and transitions to RXRPC_CALL_CLIENT_SEND_REQUEST when the first packet is transmitted. RXRPC_CALL_CLIENT_AWAIT_REPLY is then narrowed in scope to indicate that all Tx packets have been ACK'd and we're now waiting for the reply to be received. (2) As per Wyatt Feng's original patch[1], the ACKALL handler then checks that the call state is one in which there might be stuff in the Tx buffer to ACK, but now this includes AWAIT_ACK rather than AWAIT_REPLY. ACKALL packets are ignored if received in the wrong state. Note that unlike Wyatt Feng's patch, it's no longer necessary to check to see if the Tx buffer exists as this the state set now covers this. (3) Make the ACKALL handler use call->tx_transmitted rather than call->tx_top as the former is explicitly the highest packet seq number transmitted, whereas the latter has a looser definition. Thanks to Jeffrey Altman for a description of the history of the ACKALL packet[1]. | ||||

| CVE-2026-72492 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix use-after-free in same_client_has_lease() same_client_has_lease() returns an opinfo pointer from ci->m_op_list after dropping ci->m_lock without taking a reference. smb_grant_oplock() then dereferences that pointer in copy_lease() and when checking breaking_cnt. A concurrent close can remove the old lease from ci->m_op_list and drop the last reference before the caller uses the returned pointer, leading to a use-after-free. Take a reference when same_client_has_lease() selects an existing lease, drop any previous match while scanning, and release the returned reference in smb_grant_oplock() after copying the lease state. | ||||
