| In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-its: Avoid potential UAF in LPI translation cache There is a potential UAF scenario in the case of an LPI translation cache hit racing with an operation that invalidates the cache, such as a DISCARD ITS command. The root of the problem is that vgic_its_check_cache() does not elevate the refcount on the vgic_irq before dropping the lock that serializes refcount changes. Have vgic_its_check_cache() raise the refcount on the returned vgic_irq and add the corresponding decrement after queueing the interrupt. | ||||

| In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_acl_tcam: Fix stack corruption When tc filters are first added to a net device, the corresponding local port gets bound to an ACL group in the device. The group contains a list of ACLs. In turn, each ACL points to a different TCAM region where the filters are stored. During forwarding, the ACLs are sequentially evaluated until a match is found. One reason to place filters in different regions is when they are added with decreasing priorities and in an alternating order so that two consecutive filters can never fit in the same region because of their key usage. In Spectrum-2 and newer ASICs the firmware started to report that the maximum number of ACLs in a group is more than 16, but the layout of the register that configures ACL groups (PAGT) was not updated to account for that. It is therefore possible to hit stack corruption [1] in the rare case where more than 16 ACLs in a group are required. Fix by limiting the maximum ACL group size to the minimum between what the firmware reports and the maximum ACLs that fit in the PAGT register. Add a test case to make sure the machine does not crash when this condition is hit.

| In the Linux kernel, the following vulnerability has been resolved: tls: fix race between tx work scheduling and socket close Similarly to previous commit, the submitting thread (recvmsg/sendmsg) may exit as soon as the async crypto handler calls complete(). Reorder scheduling the work before calling complete(). This seems more logical in the first place, as it's the inverse order of what the submitting thread will do. | ||||

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

| In the Linux kernel, the following vulnerability has been resolved: tls: fix race between async notify and socket close The submitting thread (one which called recvmsg/sendmsg) may exit as soon as the async crypto handler calls complete() so any code past that point risks touching already freed data. Try to avoid the locking and extra flags altogether. Have the main thread hold an extra reference, this way we can depend solely on the atomic ref counter for synchronization. Don't futz with reiniting the completion, either, we are now tightly controlling when completion fires. | ||||

| In the Linux kernel, the following vulnerability has been resolved: net: tls: fix use-after-free with partial reads and async decrypt tls_decrypt_sg doesn't take a reference on the pages from clear_skb, so the put_page() in tls_decrypt_done releases them, and we trigger a use-after-free in process_rx_list when we try to read from the partially-read skb. | ||||

| In the Linux kernel, the following vulnerability has been resolved: misc: pci_endpoint_test: Free IRQs before removing the device In pci_endpoint_test_remove(), freeing the IRQs after removing the device creates a small race window for IRQs to be received with the test device memory already released, causing the IRQ handler to access invalid memory, resulting in an oops. Free the device IRQs before removing the device to avoid this issue. | ||||
| CVE-2023-54325 | 1 Linux | 1 Linux Kernel | 2026-08-04 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: crypto: qat - fix out-of-bounds read When preparing an AER-CTR request, the driver copies the key provided by the user into a data structure that is accessible by the firmware. If the target device is QAT GEN4, the key size is rounded up by 16 since a rounded up size is expected by the device. If the key size is rounded up before the copy, the size used for copying the key might be bigger than the size of the region containing the key, causing an out-of-bounds read. Fix by doing the copy first and then update the keylen. This is to fix the following warning reported by KASAN: [ 138.150574] BUG: KASAN: global-out-of-bounds in qat_alg_skcipher_init_com.isra.0+0x197/0x250 [intel_qat] [ 138.150641] Read of size 32 at addr ffffffff88c402c0 by task cryptomgr_test/2340 [ 138.150651] CPU: 15 PID: 2340 Comm: cryptomgr_test Not tainted 6.2.0-rc1+ #45 [ 138.150659] Hardware name: Intel Corporation ArcherCity/ArcherCity, BIOS EGSDCRB1.86B.0087.D13.2208261706 08/26/2022 [ 138.150663] Call Trace: [ 138.150668] <TASK> [ 138.150922] kasan_check_range+0x13a/0x1c0 [ 138.150931] memcpy+0x1f/0x60 [ 138.150940] qat_alg_skcipher_init_com.isra.0+0x197/0x250 [intel_qat] [ 138.151006] qat_alg_skcipher_init_sessions+0xc1/0x240 [intel_qat] [ 138.151073] crypto_skcipher_setkey+0x82/0x160 [ 138.151085] ? prepare_keybuf+0xa2/0xd0 [ 138.151095] test_skcipher_vec_cfg+0x2b8/0x800 | ||||

| CVE-2023-54317 | 1 Linux | 1 Linux Kernel | 2026-08-04 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: dm flakey: don't corrupt the zero page When we need to zero some range on a block device, the function __blkdev_issue_zero_pages submits a write bio with the bio vector pointing to the zero page. If we use dm-flakey with corrupt bio writes option, it will corrupt the content of the zero page which results in crashes of various userspace programs. Glibc assumes that memory returned by mmap is zeroed and it uses it for calloc implementation; if the newly mapped memory is not zeroed, calloc will return non-zeroed memory. Fix this bug by testing if the page is equal to ZERO_PAGE(0) and avoiding the corruption in this case. | ||||

Since there was no longer a call to snd_card_free, unloading the module would eventually result in Oops: [697561.532887] BUG: unable to handle page fault for address: ffffffffc0924480 [697561.532893] #PF: supervisor read access in kernel mode [697561.532896] #PF: error_code(0x0000) - not-present page [697561.532899] PGD ae1e15067 P4D ae1e15067 PUD ae1e17067 PMD 11a8f5067 PTE 0 [697561.532905] Oops: 0000 [#1] PREEMPT SMP NOPTI [697561.532909] CPU: 21 PID: 5080 Comm: wireplumber Tainted: G W OE 6.2.7 #1 [697561.532914] Hardware name: System manufacturer System Product Name/TUF GAMING X570-PLUS, BIOS 4408 10/28/2022 [697561.532916] RIP: 0010:try_module_get.part.0+0x1a/0xe0 [697561.532924] Code: 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 0f 1f 44 00 00 55 48 89 e5 41 55 41 54 49 89 fc bf 01 00 00 00 e8 56 3c f8 ff <41> 83 3c 24 02 0f 84 96 00 00 00 41 8b 84 24 30 03 00 00 85 c0 0f [697561.532927] RSP: 0018:ffffbe9b858c3bd8 EFLAGS: 00010246 [697561.532930] RAX: ffff9815d14f1900 RBX: ffff9815c14e6000 RCX: 0000000000000000 [697561.532933] RDX: 0000000000000000 RSI: ffffffffc055092c RDI: ffffffffb3778c1a [697561.532935] RBP: ffffbe9b858c3be8 R08: 0000000000000040 R09: ffff981a1a741380 [697561.532937] R10: ffffbe9b858c3c80 R11: 00000009d56533a6 R12: ffffffffc0924480 [697561.532939] R13: ffff9823439d8500 R14: 0000000000000025 R15: ffff9815cd109f80 [697561.532942] FS: 00007f13084f1f80(0000) GS:ffff9824aef40000(0000) knlGS:0000000000000000 [697561.532945] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [697561.532947] CR2: ffffffffc0924480 CR3: 0000000145344000 CR4: 0000000000350ee0 [697561.532949] Call Trace: [697561.532951] <TASK> [697561.532955] try_module_get+0x13/0x30 [697561.532960] snd_ctl_open+0x61/0x1c0 [snd] [697561.532976] snd_open+0xb4/0x1e0 [snd] [697561.532989] chrdev_open+0xc7/0x240 [697561.532995] ? fsnotify_perm.part.0+0x6e/0x160 [697561.533000] ? __pfx_chrdev_open+0x10/0x10 [697561.533005] do_dentry_open+0x169/0x440 [697561.533009] vfs_open+0x2d/0x40 [697561.533012] path_openat+0xa9d/0x10d0 [697561.533017] ? debug_smp_processor_id+0x17/0x20 [697561.533022] ? trigger_load_balance+0x65/0x370 [697561.533026] do_filp_open+0xb2/0x160 [697561.533032] ? _raw_spin_unlock+0x19/0x40 [697561.533036] ? alloc_fd+0xa9/0x190 [697561.533040] do_sys_openat2+0x9f/0x160 [697561.533044] __x64_sys_openat+0x55/0x90 [697561.533048] do_syscall_64+0x3b/0x90 [697561.533052] entry_SYSCALL_64_after_hwframe+0x72/0xdc [697561.533056] RIP: 0033:0x7f1308a40db4 [697561.533059] Code: 24 20 eb 8f 66 90 44 89 54 24 0c e8 46 68 f8 ff 44 8b 54 24 0c 44 89 e2 48 89 ee 41 89 c0 bf 9c ff ff ff b8 01 01 00 00 0f 05 <48> 3d 00 f0 ff ff 77 32 44 89 c7 89 44 24 0c e8 78 68 f8 ff 8b 44 [697561.533062] RSP: 002b:00007ffcce664450 EFLAGS: 00000293 ORIG_RAX: 0000000000000101 [697561.533066] RAX: ffffffffffffffda RBX: 0000000000000003 RCX: 00007f1308a40db4 [697561.533068] RDX: 0000000000080000 RSI: 00007ffcce664690 RDI: 00000000ffffff9c [697561.533070] RBP: 00007ffcce664690 R08: 0000000000000000 R09: 0000000000000012 [697561.533072] R10: 0000000000000000 R11: 0000000000000293 R12: 0000000000080000 [697561.533074] R13: 00007f13054b069b R14: 0000565209f83200 R15: 0000000000000000 [697561.533078] </TASK> | ||||

| In the Linux kernel, the following vulnerability has been resolved: net: tls: avoid hanging tasks on the tx_lock syzbot sent a hung task report and Eric explains that adversarial receiver may keep RWIN at 0 for a long time, so we are not guaranteed to make forward progress. Thread which took tx_lock and went to sleep may not release tx_lock for hours. Use interruptible sleep where possible and reschedule the work if it can't take the lock.

| CVE-2023-54303 | 1 Linux | 1 Linux Kernel | 2026-08-04 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Disable preemption in bpf_perf_event_output The nesting protection in bpf_perf_event_output relies on disabled preemption, which is guaranteed for kprobes and tracepoints. However bpf_perf_event_output can be also called from uprobes context through bpf_prog_run_array_sleepable function which disables migration, but keeps preemption enabled. This can cause task to be preempted by another one inside the nesting protection and lead eventually to two tasks using same perf_sample_data buffer and cause crashes like: kernel tried to execute NX-protected page - exploit attempt?
