| CVE-2026-72472 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: nfs: use nfsi->rwsem to protect traversal of the file lock list Lingfeng identified a bug and suggested two solutions, but both appear to have issues. Generally, we cannot release flc_lock while iterating over the file lock list to avoid use-after-free (UAF) problems with file locks. However, functions like nfs_delegation_claim_locks and nfs4_reclaim_locks cannot adhere to this rule because recover_lock or nfs4_lock_delegation_recall may take a long time. To resolve this, NFS switches to using nfsi->rwsem for the same protection, and nfs_reclaim_locks follows this approach. Although nfs_delegation_claim_locks uses so_delegreturn_mutex instead, this is inadequate since a single inode can have multiple nfs4_state instances. Therefore, the fix is to also use nfsi->rwsem in this case. Furthermore, after commit c69899a17ca4 ("NFSv4: Update of VFS byte range lock must be atomic with the stateid update"), the functions nfs4_locku_done and nfs4_lock_done also break this rule because they call locks_lock_inode_wait without holding nfsi->rwsem. Simply adding this protection could cause many deadlocks, so instead, the call to locks_lock_inode_wait is moved into _nfs4_proc_setlk. Regarding the bug fixed by commit c69899a17ca4 ("NFSv4: Update of VFS byte range lock must be atomic with the stateid update"), it has been resolved after commit 0460253913e5 ("NFSv4: nfs4_do_open() is incorrectly triggering state recovery") because all slots are drained before calling nfs4_do_reclaim, which prevents concurrent stateid changes along this path. Also, nfs_delegation_claim_locks does not cause this concurrency either since when _nfs4_proc_setlk is called with NFS_DELEGATED_STATE, no RPC is sent, so nfs4_lock_done is not called. Therefore, nfs4_lock_delegation_recall from nfs_delegation_claim_locks is the first time the stateid is set. | ||||
| CVE-2026-72481 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: iio: magnetometer: ak8975: fix potential kernel stack memory leak Currently in the AK8975 driver there are four instances where potential uninitialized kernel stack memory leaks can occur. If i2c_smbus_read_i2c_block_data_or_emulated() returns a value less than the size of the buffer, uninitialized bytes are retained in the buffer and later the buffer is passed on to IIO buffers, potentially leaking memory to userspace. Fix this by adding checks whether the return value of the function is equal to the size of the buffer and subsequently if the value is lesser than zero to distinguish from a returned error code. | ||||

| In the Linux kernel, the following vulnerability has been resolved: ASoC: meson: aiu: Validate written enum values The AIU HDMI and internal codec mux put callbacks use the written enum value with snd_soc_enum_item_to_val() before checking whether the value is valid for the enumeration. Reject out-of-range values before converting the enum item, matching the validation already done by the G12A HDMI and internal codec mux controls. | ||||

| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btmtk: fix URB leak in alloc_mtk_intr_urb error path When btmtk_isopkt_pad() fails, the previously allocated URB is not freed, leaking the urb structure. Add usb_free_urb() before returning the error. | ||||
| CVE-2026-74303 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_qca: fix NULL pointer dereference in qca_dmp_hdr() for non-serdev device hu->serdev is NULL for hci_uart attached via non-serdev paths, but qca_dmp_hdr() unconditionally dereferences hu->serdev->dev.driver->name, causing a NULL pointer dereference. Fix by guarding the dereference with a NULL check and falling back to "hci_ldisc_qca" for the non-serdev case. | ||||

| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: Fix possible NULL pointer dereference in mt7996_mac_write_txwi_80211() For injected frames (e.g. via radiotap), mac80211 can pass info->control.vif = NULL, as explicitly noted in struct ieee80211_tx_info. Check vif pointer before executing ieee80211_vif_is_mld() in mt7996_mac_write_txwi_80211 routine in order to avoid a possible NULL pointer dereference. | ||||

| In the Linux kernel, the following vulnerability has been resolved: wifi: wcn36xx: fix OOB read from firmware count in PRINT_REG_INFO indication The firmware-controlled rsp->count field is used as the loop bound for indexing into the flexible rsp->regs[] array without validation against the message length. A count exceeding the actual data causes out-of- bounds reads from the heap-allocated message buffer. Add a check that count fits within the received message. | ||||

| CVE-2026-74478 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: um: vector: fix use-after-free in vector_mmsg_rx() When vector_mmsg_rx() discards a packet whose overlay header fails verify_header(), it frees the skb and continues the loop: if (header_check < 0) { dev_kfree_skb_irq(skb); vp->estats.rx_encaps_errors++; continue; } The normal and short-packet paths fall through to the bottom of the loop body, which clears the consumed slot and advances the cursors: (*skbuff_vector) = NULL; mmsg_vector++; skbuff_vector++; The verify_header() < 0 path skips that via continue, so the freed skb is left in skbuff_vector[] and the cursors do not advance. The next iteration reads the same slot, gets the freed skb, and frees it again, producing a refcount underflow / use-after-free in the RX path. Discard the slot the same way the other paths do before continuing. Only transports whose verify_header() can return negative are affected: GRE and L2TPv3 do so on a cookie/session-id mismatch (raw/tap do not), so any peer on such a transport can trigger it without authentication. | ||||
| CVE-2026-72486 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: mailbox: mtk-adsp: fix UAF during device teardown When the SOF audio driver fails to initialize (e.g. firmware boot timeout), its devres unwind frees the snd_sof_dev object that the mailbox client (mtk-adsp-ipc) reaches via chan->cl->rx_callback. The mtk-adsp-mailbox shutdown clears the mailbox command registers but leaves the IRQ line unmasked, so a late interrupt can still queue a threaded handler after mbox_free_channel() had cleared chan->cl, and mbox_chan_received_data() would then trigger UAF: BUG: KASAN: slab-use-after-free in sof_ipc3_validate_fw_version sof_ipc3_validate_fw_version sof_ipc3_do_rx_work sof_ipc3_rx_msg mt8196_dsp_handle_request mtk_adsp_ipc_recv mbox_chan_received_data mtk_adsp_mbox_isr irq_thread_fn Freed by task ...: kfree devres_release_all really_probe ... (sof-audio-of-mt8196 probe failure) The crash was observed roughly three seconds after the failed probe. disable_irq() in shutdown and enable_irq() in startup. disable_irq() also waits for any in-flight interrupts, so by the time mbox_free_channel() proceeds to clear chan->cl no rx_callback can run. In addition, request the IRQ with IRQF_NO_AUTOEN so it stays masked between probe and the first client bind — otherwise an early interrupt can crash on chan->cl == NULL in mbox_chan_received_data(). | ||||
| CVE-2026-74287 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: sctp: validate embedded address parameter length sctp_verify_asconf() and sctp_verify_param() only validate ADD_IP, DEL_IP, and SET_PRIMARY parameters against a fixed minimum size of sizeof(struct sctp_addip_param) + sizeof(struct sctp_paramhdr). This ensures the outer parameter is large enough to contain an embedded address parameter header, but does not verify that the embedded address parameter's declared length fits within the bounds of the outer parameter. Later, sctp_process_param() and sctp_process_asconf_param() extract the embedded address parameter and pass it to af->from_addr_param(), which uses the address parameter length to parse the variable-length address payload. A malformed peer can therefore advertise an embedded address parameter length that exceeds the remaining bytes in the enclosing parameter. Validate that addr_param->p.length does not exceed the space available after the sctp_addip_param header before processing the embedded address parameter. Reject malformed parameters when the embedded address length extends beyond the enclosing parameter bounds. This prevents out-of-bounds reads when parsing malformed parameters carried in INIT or ASCONF processing paths. | ||||
| CVE-2026-74292 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ASoC: tegra: tegra210_ahub: Validate written enum value tegra_ahub_put_value_enum() reads e->values[item[0]] before checking whether item[0] is within the enum item range. The existing check therefore happens too late to prevent an out-of-range read of the values array. Move the check before the array access. | ||||
| CVE-2026-74304 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_qca: fix NULL pointer dereference in qca_setup() for non-serdev device hu->serdev is NULL for hci_uart attached via non-serdev paths, but qca_setup() unconditionally calls serdev_device_get_drvdata(hu->serdev) and dereferences the result, causing a NULL pointer dereference. Fix by guarding the dereference with a NULL check, consistent with the rest of qca_setup(). | ||||
| CVE-2026-74323 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: Fix possible token leak in mt7996_tx_prepare_skb() If link_conf or link_sta lookup fails in mt7996_tx_prepare_skb routine, mt7996 driver leaks an already allocated tx token. Fix the issue releasing the token in case of error. | ||||
| CVE-2026-74324 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: validate skb length in testmode query In mt7925_tm_query(), the response skb from mt76_mcu_send_and_get_msg() is used in a memcpy without validating its length: memcpy(evt_resp, skb->data + 8, MT7925_EVT_RSP_LEN); where MT7925_EVT_RSP_LEN is 512. If the firmware returns a response shorter than 520 bytes (8 + 512), this reads beyond the skb data buffer. The over-read data is then returned to userspace via nla_put() in mt7925_testmode_dump(). Add a length check before the memcpy to ensure the skb contains sufficient data. | ||||
| CVE-2026-74370 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: liveupdate: fix TOCTOU race in luo_session_retrieve() Extend the scope of the rwsem_read lock in luo_session_retrieve() to overlap with the acquisition of the session mutex. This prevents a concurrent thread from releasing and freeing the session between the lookup and the mutex lock. | ||||
| CVE-2026-74395 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix devx subscribe-event unwind NULL dereference MLX5_IB_METHOD_DEVX_SUBSCRIBE_EVENT() links event_sub into sub_list before initializing the fields used by the shared error path. If eventfd_ctx_fdget() then fails, the unwind path dereferences event_sub->ev_file in uverbs_uobject_put() and calls subscribe_event_xa_dealloc() with an unset xa_key_level1. subscribe_event_xa_alloc() creates the XA entry exactly once for a given key_level1, on the first occurrence of that key. The unwind path must therefore call subscribe_event_xa_dealloc() exactly once for it as well. Enforce that by adding devx_key_in_sub_list() and calling subscribe_event_xa_dealloc() only when the last matching pending entry is being cleaned up. | ||||
| CVE-2026-74397 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: IB/mlx5: Fix transport-domain rollback and initialize lb mutex earlier mlx5_ib_alloc_transport_domain() allocates a transport domain and then may fail in mlx5_ib_enable_lb(). In that case, the allocated TD is leaked. Fix this by deallocating the TD when mlx5_ib_enable_lb() returns an error. Also return 0 explicitly in the no-loopback-capability success branch, and move dev->lb.mutex initialization to mlx5_ib_stage_init_init(). | ||||
| CVE-2026-74434 | 1 Linux | 1 Linux Kernel | 2026-08-15 | N/A |
| 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. | ||||
