| CVE-2026-72064 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: net: mana: Sync page pool RX frags for CPU MANA allocates RX buffers from page pool fragments when frag_count is greater than 1. In that case the buffers remain DMA mapped by page pool and the RX completion path does not call dma_unmap_single(). As a result, the implicit sync-for-CPU normally performed by dma_unmap_single() is missing before the packet data is passed to the networking stack. This breaks RX on configurations which require explicit DMA syncing, for example when booted with swiotlb=force. Fix this by recording the page pool page and DMA sync offset when the RX buffer is allocated, and syncing the received packet range for CPU access before handing the RX buffer to the stack. | ||||

| In the Linux kernel, the following vulnerability has been resolved: net: mana: Validate the packet length reported by the NIC Validate the packet length reported in the RX CQE before passing it to skb processing. The CQE is supplied by the NIC device and should not be blindly trusted. | ||||
| CVE-2026-72066 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: cpu: hotplug: Bound hotplug states sysfs output states_show() adds CPU hotplug state names into a single sysfs buffer using sprintf(). With enough registered states, this can write past the end of the PAGE_SIZE buffer. Use sysfs_emit_at() so output is bounded. | ||||
| CVE-2026-72067 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: cpu: hotplug: Preserve per instance callback errors cpuhp_invoke_callback() unwinds earlier callbacks for the same hotplug state when one instance fails. The rollback path currently reuses ret, so a successful rollback can hide the original error and make the failed transition look successful. Keep the rollback result separate from the original error. | ||||
| CVE-2026-72073 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mmc: vub300: fix use-after-free on probe failure The vub300 driver lifetime-manages its controller state using vub300->kref, with vub300_delete() freeing the mmc host when the last reference is dropped. The probe error path after the inactivity timer has been armed still bypasses that lifetime rule, however, and falls through to mmc_free_host() directly if mmc_add_host() fails. The race window is between arming the inactivity timer and reaching the probe error unwind after mmc_add_host() fails: probe thread timer/workqueue ------------ --------------- kref_init(&vub300->kref) ref = 1 kref_get(&vub300->kref) ref = 2, timer ref add_timer(inactivity_timer) fires after one second | | race window |<----------------------------------------------------> | mmc_add_host(mmc) inactivity timer fires vub300_queue_dead_work() kref_get() ref = 3 queue_work(deadwork) mmc_add_host() fails timer_delete_sync() mmc_free_host(mmc) frees vub300 deadwork runs use-after-free The inactivity timeout is one second, so this would require mmc_add_host() to both fail and take more than one second to do so. This is unlikely to happen in practice, but the error path is still wrong. timer_delete_sync() only waits for the timer callback itself. It does not flush deadwork that the callback may already have queued. As a result, queued deadwork can still hold a kref while the probe error path directly frees the backing mmc host, including the vub300 storage. Fix this by using the same lifetime mechanism as disconnect. Clear vub300->interface so that the timer callback and any queued deadwork return early and drop their references, then drop the initial probe reference and return without falling through to err_free_host. | ||||
| CVE-2026-72076 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - fix out-of-bounds read in ims_pcu_irq() debug logging The debug logging in ims_pcu_irq() unconditionally prints data from pcu->urb_in_buf. However, if the interrupt fired for pcu->urb_ctrl, the actual data resides in pcu->urb_ctrl_buf. If urb->actual_length for the control URB exceeds pcu->max_in_size, this leads to an out-of-bounds read. Fix this by printing from the correct buffer associated with the URB. | ||||

| In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - fix firmware leak in async update The firmware object was not being released if validation failed. Use __free(firmware) to ensure the firmware is always released. | ||||
| CVE-2026-72078 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - validate control endpoint type The driver currently assumes that the first endpoint of the control interface is an interrupt IN endpoint without verifying it. A malicious device could provide a different endpoint type, which would then be passed to usb_fill_int_urb(), potentially leading to kernel warnings or undefined behavior. Verify that the control endpoint is an interrupt IN endpoint. | ||||

| In the Linux kernel, the following vulnerability has been resolved: fs/resctrl: Fix use-after-free during unmount During unmount or failure teardown all mon_data structures that contain monitoring event file private data are freed after which kernfs nodes are removed. However, the RDT_DELETED flag is never set for the statically allocated default resource group. A concurrent reader of an event file associated with the default resource group may, after dropping kernfs active protection, block on rdtgroup_mutex while unmount proceeds to free the file private data and destroy the kernfs node without waiting for the reader. When the mutex is released, the reader wakes up, observes that RDT_DELETED is not set for the default group, and dereferences the already-freed file private data. The scenario can be depicted as follows: CPU0 CPU1 /* * Default resource group's * monitoring data accessible via * kernfs file with kernfs_node::priv * pointing to a struct mon_data. * User opens the file for reading. */ rdtgroup_mondata_show() /* arch encounters fatal error */ rdtgroup_kn_lock_live() resctrl_exit() atomic_inc(&rdtgroup_default.waitcount) cpus_read_lock() kernfs_break_active_protection(kn) mutex_lock(&rdtgroup_mutex) cpus_read_lock() resctrl_fs_teardown() mutex_lock(&rdtgroup_mutex) rmdir_all_sub() mon_put_kn_priv() /* Delete all mon_data structures */ rdtgroup_destroy_root() kernfs_destroy_root() rdtgroup_default.kn = NULL mutex_unlock(&rdtgroup_mutex) /* * rdtgroup_default.flags is empty so * rdtgroup_kn_lock_live() returns * &rdtgroup_default */ md = of->kn->priv; /* md points to freed mon_data */ Set RDT_DELETED for the default group unconditionally since the flag does not lead to the freeing of this statically allocated group. Do not allow a new resctrl mount if there are any waiters on default group of previous mount. A new mount will re-initialize the default group that would appear to waiters from previous mount as though the default group is accessible causing them to access the mon_data structures from the previous mount that have been removed. | ||||
| CVE-2026-72082 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: scsi: elx: efct: Fix refcount leak in efct_hw_io_abort() When efct_hw_reqtag_alloc() fails in efct_hw_io_abort(), the error path returns -ENOSPC without releasing the reference obtained via kref_get_unless_zero() earlier in the function. All other error paths correctly drop the reference. This causes a permanent reference leak on the io_to_abort object. Additionally, the abort_in_progress flag is left set to true on this path, which means future abort attempts for the same I/O will immediately return -EINPROGRESS even though the abort was never submitted, effectively blocking recovery. Fix this by adding the missing kref_put() call and reset abort_in_progress to false, matching the cleanup done in the efct_hw_wq_write() failure path below. | ||||
| CVE-2026-72096 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: dm-verity: make error counter atomic The error counter "v->corrupted_errs" was not atomic, thus it could be subject to race conditions. The call to dm_audit_log_target("max-corrupted-errors") may be skipped due to the races. | ||||
| CVE-2026-72109 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: net: sparx5: unregister blocking notifier on init failure sparx5_register_notifier_blocks() registers the switchdev blocking notifier before allocating the ordered workqueue. If the workqueue allocation fails, the error path unregisters the switchdev and netdevice notifiers, but leaves the blocking notifier registered. Add a separate error label for the workqueue allocation failure path and unregister the switchdev blocking notifier there. | ||||
| CVE-2026-72361 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/xe/hw_engine: Fix double-free of managed BO in error path The error path in hw_engine_init() explicitly frees a BO allocated with xe_managed_bo_create_pin_map() via xe_bo_unpin_map_no_vm(). Since the managed BO already has a devm cleanup action registered, this causes a double-free when devm unwinds during probe failure. Remove the explicit free and let devm handle it, consistent with all other xe_managed_bo_create_pin_map() callers. (cherry picked from commit e459a3bdeb117be496d7f229e2ea1f6c9fe4080b) | ||||
| CVE-2026-72411 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: net: dsa: mxl862xx: fix use-after-free of DSA ports in crc_err_work Upon an MDIO CRC error mxl862xx_crc_err_work_fn() walks the DSA ports and closes the CPU port conduits: dsa_switch_for_each_cpu_port(dp, priv->ds) dev_close(dp->conduit); mxl862xx_remove() unregisters the switch before cancelling this work: set_bit(MXL862XX_FLAG_WORK_STOPPED, &priv->flags); cancel_delayed_work_sync(&priv->stats_work); dsa_unregister_switch(ds); mxl862xx_host_shutdown(priv); dsa_unregister_switch() frees the dsa_port objects. If a CRC error schedules the work during teardown it can run after the ports have been freed and dereference freed memory. Guard the port walk with MXL862XX_FLAG_WORK_STOPPED, which is already set before dsa_unregister_switch(). DSA tears the ports down under rtnl_lock(), so checking the flag under rtnl_lock() means the work either runs before teardown and sees valid ports, or runs afterwards, observes the flag and skips the walk. This mirrors the host_flood_work handler, which skips torn-down ports under rtnl_lock(). | ||||
| CVE-2026-72445 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: qcom: clear opened when stream enable fails On enable, subs->opened is set before the service_interval is validated; an invalid interval jumps to the response label without clearing it, so the substream is wedged at -EBUSY until a disable or disconnect. Clear subs->opened on the enable error path. | ||||
| CVE-2026-72486 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| 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-2026-74448 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix QID bit leak in pqm_create_queue() When MES is enabled and amdgpu_amdkfd_alloc_kernel_mem() fails during the first queue creation for a process, pqm_create_queue() returns early via 'return retval' without going through the err_create_queue cleanup label. This means clear_bit(*qid, pqm->queue_slot_bitmap) is never called, leaving the reserved QID bit permanently set in queue_slot_bitmap. Over time this leaks QID slots, potentially exhausting all available queue slots. Fix this by replacing 'return retval' with 'goto err_allocate_pqn' so that clear_bit() is always called on the error path without touching the uninitialized pqn pointer. AILIKFD-813 (cherry picked from commit a107f74c38edbb80d6ab64dcaeeb292c14e9779f) | ||||
| CVE-2026-74475 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 10 Critical |
| In the Linux kernel, the following vulnerability has been resolved: vxlan: use neigh_ha_snapshot() in route_shortcircuit() The neighbour hardware address n->ha can be updated asynchronously by the neighbour subsystem, protected by n->ha_lock seqlock. Reading n->ha without holding the seqlock loop can lead to torn reads or reading a partially updated MAC address. Use neigh_ha_snapshot() in route_shortcircuit() to safely copy n->ha under read_seqbegin()/read_seqretry() lock protection before using it. Note that arp_reduce() and neigh_reduce() seem to have the same issue left for future patches. | ||||
| CVE-2026-74508 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: HIDP: reject frames without a transaction header hidp_recv_ctrl_frame() and hidp_recv_intr_frame() read skb->data[0] before checking that the L2CAP SDU contains a transaction header. A connected HIDP peer can send an empty basic-mode SDU and make both paths use an uninitialized byte from skb tailroom. KMSAN reports the use in hidp_session_run(), with the uninitialized value originating in __alloc_skb() through vhci_write(). The control path produces two reports and the interrupt path produces one. The byte can also be controlled by a malformed lower-layer packet. If an HCI ACL packet contains an L2CAP PDU with a declared zero-length payload followed by an extra 0x15 byte, l2cap_recv_acldata() reduces skb->len to the declared PDU length before dispatch. The current HIDP path nevertheless consumes the extra byte as HIDP_TRANS_HID_CONTROL | HIDP_CTRL_VIRTUAL_CABLE_UNPLUG and terminates the HIDP session. With this change, the same packet is discarded and a subsequent feature report request succeeds. Pull the transaction header with skb_pull_data() and discard frames that do not contain it. | ||||
| CVE-2026-74528 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 8 High |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_sync: hold conn in hci_past_sync() callback Avoids giving freed pointers to hci_conn_valid(), which kmalloc may have reused. Hold refcount to avoid that. | ||||
