| CVE-2026-68205 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: media: v4l2-fwnode: Fix subdev owner overwritten in v4l2_async_register_subdev_sensor() The v4l2 helper v4l2_async_register_subdev_sensor() calls v4l2_async_register_subdev(), which is a macro that expands to __v4l2_async_register_subdev(sd,THIS_MODULE). Since the macro is expanded inside v4l2-fwnode.c, THIS_MODULE resolves to the v4l2-fwnode module rather than the sensor driver module that originally set sd->owner. When v4l2-fwnode is built-in, THIS_MODULE evaluates to NULL, which then overwrites the sensor driver's owner with NULL. This causes the problem that the sensor module's reference count is never incremented during async registration, so the module can be removed while the subdevice is still in use by a notifier (e.g., a CSI-2 receiver bridge driver). Fix this by renaming v4l2_async_register_subdev_sensor() to __v4l2_async_register_subdev_sensor() with an added explicit module argument and introducing a wrapper macro: #define v4l2_async_register_subdev_sensor(sd) \ __v4l2_async_register_subdev_sensor(sd, THIS_MODULE) This ensures the sensor driver module is properly referenced even when the sensor driver does not init the owner field before calling v4l2_async_register_subdev_sensor() and prevents premature module removal. | ||||
| CVE-2026-68203 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: media: vivid: fix cleanup bugs in vivid_init() When platform_device_register() fails in vivid_init(), the embedded struct device in vivid_pdev has already been initialized by device_initialize(), but the failure path jumps to free_output_strings without dropping the device reference for the current platform device: vivid_init() -> platform_device_register(&vivid_pdev) -> device_initialize(&vivid_pdev.dev) -> setup_pdev_dma_masks(&vivid_pdev) -> platform_device_add(&vivid_pdev) This leads to a reference leak when platform_device_register() fails. Fix this by calling platform_device_put() before jumping to the common cleanup path. Also, the unreg_driver label incorrectly calls platform_driver_register() instead of platform_driver_unregister(), which breaks cleanup when workqueue creation fails after successful driver registration. Fix that as well. The reference leak was identified by a static analysis tool I developed and confirmed by manual review. The incorrect cleanup call was found during code inspection. | ||||
| CVE-2026-68199 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: ath6kl: fix OOB access from firmware ADDBA window size aggr_recv_addba_req_evt() logs a debug message when the firmware-supplied win_sz is outside [AGGR_WIN_SZ_MIN, AGGR_WIN_SZ_MAX] but does not return. The out-of-range win_sz is then used in TID_WINDOW_SZ() to compute a kzalloc size and stored in rxtid->hold_q_sz, leading to zero-size or overflowed allocations and subsequent out-of-bounds access. Clean up any previously active aggregation session for the TID first, then return early when win_sz is out of the valid range, instead of proceeding with a broken allocation size. | ||||
| CVE-2026-68198 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: ath6kl: fix use-after-free in aggr_reset_state() The aggr_reset_state() function uses timer_delete() (non-synchronous) for the aggregation timer before proceeding to delete TID state and before the structure is freed by callers like aggr_module_destroy(). If the timer callback (aggr_timeout) is executing when aggr_reset_state() is called, the callback will continue to access aggr_conn fields like rx_tid[] and stat[] which may be freed immediately after by kfree(aggr_info->aggr_conn) in aggr_module_destroy(). Additionally, the timer callback can re-arm itself via mod_timer() while aggr_reset_state() is running, creating a more complex race condition. Use timer_delete_sync() instead to ensure any running timer callback has completed before returning. | ||||
| CVE-2026-68196 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: wilc1000: validate assoc response length before subtracting header wilc_parse_assoc_resp_info() computes the trailing IE length as ies_len = buffer_len - sizeof(*res); without first checking that buffer_len is at least sizeof(struct wilc_assoc_resp) (6 bytes). buffer_len is the length reported for a received association response (host_int_parse_assoc_resp_info() passes hif_drv->assoc_resp / assoc_resp_info_len straight in) and must be validated before the driver accesses the fixed header. For a frame shorter than the 6-byte fixed header, the subtraction wraps. For a four-byte response the result is truncated to a u16 ies_len of 65534, so kmemdup() then attempts to copy 65534 bytes starting at buffer + sizeof(*res), beyond the valid association-response data (CWE-125). A response shorter than four bytes can also cause an out-of-bounds read of res->status_code at offsets 2 and 3. Reject frames too short to hold the fixed header before touching the header or computing ies_len. Also set the connection status to a failure on this path: the caller falls through to a "conn_info->status == WLAN_STATUS_SUCCESS" check after the parser returns, so leaving the status untouched could let a malformed short response be treated as a successful association. | ||||
| CVE-2026-68194 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: drop TXRX_NOTIFY on non-mmio buses PKT_TYPE_TXRX_NOTIFY is an mmio-only event, but mt7921_rx_check() and mt7921_queue_rx_skb() dispatch it to mt7921_mac_tx_free() on every bus. mt7921_mac_tx_free() cleans the DMA tx queues with mt76_queue_tx_cleanup(), which calls queue_ops->tx_cleanup(). Only the mmio queue ops implement that callback; on USB and SDIO it is NULL, so a TXRX_NOTIFY there calls a NULL pointer in the RX worker: BUG: kernel NULL pointer dereference, address: 0000000000000000 RIP: 0010:0x0 Call Trace: mt7921_mac_tx_free+0x64/0x310 [mt7921_common] mt7921_rx_check+0x5f/0xf0 [mt7921_common] mt76u_rx_worker+0x1b9/0x620 [mt76_usb] Drop the event on non-mmio buses via mt76_is_mmio(), as in commit 5683e1488aa9 ("wifi: mt76: connac: do not check WED status for non-mmio devices"). | ||||
| CVE-2026-68192 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: make release_scratchbuffers idempotent brcmf_pcie_release_scratchbuffers() frees the shared.scratch and shared.ringupd DMA buffers with dma_free_coherent() but does not clear the pointers afterwards, unlike the sibling release_ringbuffers() which NULLs commonrings/flowrings/idxbuf on release. Both the bus_reset .reset callback (brcmf_pcie_reset) and brcmf_pcie_remove() call release_scratchbuffers. When reset teardown has run before removal, remove's own teardown would call dma_free_coherent() a second time on the already-freed DMA allocation. NULL the pointers after free, matching release_ringbuffers(), so a later release observes that the allocation has already been released. This patch makes repeated sequential release safe; the reset-work lifetime is handled separately by the following patch. This issue was found by an in-house static analysis tool. | ||||
| CVE-2026-44630 | 1 Apache | 1 Iotdb | 2026-08-10 | N/A |
| Improper validation of length fields in the Apache IoTDB RPC service may allow a remote unauthenticated attacker to cause a denial of service. By sending a crafted malformed Thrift frame, an attacker can cause IoTDB to allocate an excessive amount of memory and crash with an OutOfMemoryError. This issue affects Apache IoTDB: before 1.3.8, from 2.0.0 before 2.0.9. Users are recommended to upgrade to version 2.0.10, which fixes the issue. | ||||

| CVE-2026-68189 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_sync: Protect UUID list traversal The hci_sync conversion moved class-of-device and EIR generation from an HCI request built under hdev->lock to asynchronous command sync work. The worker holds hdev->req_lock, but that lock does not serialize access to hdev->uuids against add_uuid() and remove_uuid(), which update the list under hdev->lock. The following interleaving can therefore occur: CPU0 (command sync work) CPU1 (management socket) fetch uuid from the list list_del(&uuid->list) kfree(uuid) read uuid->size KASAN reports the resulting use-after-free: BUG: KASAN: slab-use-after-free in eir_create+0xb8f/0xee0 Read of size 1 at addr ffff88810dbd8620 by task kworker/u17:0/87 Workqueue: hci0 hci_cmd_sync_work Call Trace: eir_create+0xb8f/0xee0 hci_update_eir_sync+0x1c0/0x330 hci_cmd_sync_work+0x13c/0x290 process_one_work+0x63a/0x1070 worker_thread+0x45b/0xd10 Allocated by task 86: __kasan_kmalloc+0x8f/0xa0 add_uuid+0x18a/0x4b0 hci_sock_sendmsg+0x1033/0x1ea0 Freed by task 92: __kasan_slab_free+0x43/0x70 kfree+0x131/0x3c0 remove_uuid+0x25e/0x560 hci_sock_sendmsg+0x1033/0x1ea0 Hold hdev->lock while generating and committing the class-of-device and EIR snapshots. Release it before sending an HCI command, so controller waits do not happen under the device lock. This protects all UUID list walks in these paths and restores the serialization lost in the command sync conversion. | ||||
| CVE-2026-68186 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: binfmt_misc: set have_execfd only once the interpreter is opened load_misc_binary() raises bprm->have_execfd as soon as it sees the 'O' (or 'C') flag. This happens well before it opens the interpreter. If that open fails the flag stays set on the bprm. binfmt_misc is at the head of the format list so an interpreter open failure that returns -ENOEXEC lets the search fall through to a later format. This means it runs the matched binary directly having never staged an interpreter. So bprm->executable is NULL while have_execfd falsely claims a descriptor is present. Consequently, begin_new_exec() dereferences the missing executable: would_dump(bprm, bprm->executable); and NULL derefs. Had it not, the hand-off later in the same function would have failed anyway. FD_ADD(0, bprm->executable) rejects a NULL file with -ENOMEM. Both sites are past the point of no return so the exec cannot be unwound either way. This can be reached by unprivileged users as binfmt_misc can be mounted in user namespaces. So a user can register an 'O' entry whose interpreter lives on a FUSE mount, have the FUSE server fail the open with -ENOEXEC and execute a native ELF file that matches the entry. have_execfd only means anything alongside the executable it describes which is not set until the interpreter has been opened and staged. So lets raise it there, next to execfd_creds, which is already set at that point. An open failure now leaves it clear, so the fallback format derives credentials from the binary and emits no AT_EXECFD, as it would for any native exec. The argv rewrite load_misc_binary() performs before the open is still not undone. This means the binary sees the interpreter path in argv[0] and its own path in argv[1] but that predates this change and only became observable once the exec stopped faulting. | ||||
| CVE-2026-68185 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: LoongArch: Move jump_label_init() before parse_early_param() When enabling both CONFIG_MEM_ALLOC_PROFILING=y and CONFIG_MEM_ALLOC_PROFILING_ENABLED_BY_DEFAULT=y, then diabling memory profiling by adding the boot parameter 'sysctl.vm.mem_profiling=0' will cause the kernel failed to boot. After analysis, this is because jump_label_init() must be called before parse_early_param(), the early param handlers may modify static keys by static_branch_enable/disable(). Fix this by moving jump_label_init() to before parse_early_param(). The solution is similar to other architectures. | ||||
| CVE-2026-68184 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: cdrom: fix stack out-of-bounds read in CDROMVOLCTRL mmc_ioctl_cdrom_volume() first reads the audio control mode page into a 32-byte stack buffer with cgc->buflen set to 24. If the device reports a block descriptor, the function increases cgc->buflen to include that descriptor and reads the page again. For CDROMVOLCTRL, the function then builds a MODE SELECT parameter list by moving cgc->buffer forward by offset - 8 bytes. This drops the block descriptor from the outgoing payload and leaves a new 8-byte mode parameter header in front of the audio control page. However, cgc->buflen is left unchanged. With a standard 8-byte block descriptor, cgc->buffer points at buffer + 8 but cgc->buflen remains 32. cdrom_mode_select() therefore asks the low level packet path to write 32 bytes from that adjusted pointer, reading 8 bytes past the end of the 32-byte stack buffer. This is not hit by CDROMVOLREAD, and CDROMVOLCTRL only triggers it on drives that return a non-zero block descriptor length, which helps explain why it has gone unnoticed. The overread is also sent to the device as extra MODE SELECT payload, so it may not produce an obvious local failure. Reduce cgc->buflen by the same amount as the buffer pointer adjustment so the MODE SELECT transfer covers only the intended parameter list. | ||||
| CVE-2026-68183 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: firmware: stratix10-svc: fix memory leaks and list corruption bugs Fix a memory leak when gen_pool_alloc() fails by freeing pmem on the error path. Switch pmem allocation from devm_kzalloc() to kzalloc() with explicit kfree() in the free path to match its list-managed lifetime. Remove the erroneous list_del(&svc_data_mem) which corrupted the list head on failed lookups. | ||||
| CVE-2026-68182 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: comedi: comedi_parport: deal with premature interrupt Syzbot reported a general protection fault in `comedi_get_is_subdevice_running()`, which was called from the interrupt handler `parport_interrupt()` in the "comedi_parport" driver, but it does not currently have a C reproducer for the problem. It's probably due to a premature interrupt for one of two reasons: 1. The driver sets up the interrupt handler before the comedi subdevices used by the interrupt handler have been allocated, but does not disable the interrupt in the parallel port's CTRL register first. 2. The driver uses a user-supplied I/O port base address which Syzbot would have supplied, but it might not be backed by real parallel port hardware. Change the initialization order in the driver's comedi "attach" handler (`parport_attach()`) so that the hardware registers are initialized before the interrupt handler is requested. This should prevent premature interrupts occurring for real hardware. Also add a test to the interrupt handler to ensure the comedi device is fully attached and return early if it isn't. | ||||
| CVE-2026-68181 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: mei: bus: access mei_device under device_lock on cleanup Fix couple of problems in mei_cl_bus_dev_release(): mei_cl_flush_queues() is running without lock. bus->file_list access after mei_dev_bus_put(bus) can become a use-after-free if this was the last reference to bus. Protect queues cleanup and WARN traversal by device lock there to avoid the concurrent access problems. Move WARN traversal before mei_dev_bus_put(bus). This file uses bus variable name for mei_device, adjust code of mei_cl_bus_dev_release() to use bus variable too. | ||||
| CVE-2026-68178 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: misc: nsm: pin the module while the device is open misc_open() installs a misc driver's file operations with fops_get(), which pins file_operations::owner before replacing the file's f_op. The NSM misc device leaves nsm_dev_fops.owner unset, so opening /dev/nsm does not take a module reference on the nsm driver. If the driver is built as a module, an open file descriptor can therefore survive rmmod of the module that provides its ioctl callbacks. A later ioctl through that descriptor can call into unloaded module text. Set nsm_dev_fops.owner to THIS_MODULE so the misc core holds the module while any /dev/nsm file descriptor is open, matching the lifetime expectation for the installed file operations. | ||||
| CVE-2026-68177 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: tracing: Delay module ref count for "enable_event" trigger Triggers are now delayed from freeing, but can still be triggered until after the RCU grace period has ended. The freeing of the enable_event data is put into the private_data_free() callback, but the put of the module refcount is done immediately. It is possible that if a module is removed that has an event that would enable (or disable) it is still active, it can read the data of the module after it is removed causing a use-after-free bug. Move the trace_event_put_ref() that releases the module into the delayed callback so that the module can not be removed until any reference to its events are finished. | ||||
| CVE-2026-68176 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: tracing: Fix mmiotrace possible NULL dereferencing of hiter->dev If the mmio_pipe_open() fails to find a PCI device, the hiter->dev will be assigned to NULL. The mmiotrace read() function dereferences the hiter->dev if hiter exists. Change the test of the read to not only check hiter being NULL, but also the hiter->dev before dereferencing it. | ||||
| CVE-2026-68173 | 1 Linux | 1 Linux Kernel | 2026-08-10 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ublk: wait on ublk_dev_ready() instead of ub->completion ub->completion is only re-armed by a successful START_USER_RECOVERY. If the ublk server sends END_USER_RECOVERY without one - e.g. its START failed with -EBUSY and the error was ignored - the wait is satisfied by the stale completion of the previous recovery cycle, and the device is marked LIVE and the requeue list kicked while the FETCH stream is still running and ubq->canceling is still set. The kick redispatches a previously requeued request, __ublk_queue_rq_common() sees ->canceling and parks it again via __ublk_abort_rq(), and after the last FETCH clears ->canceling nothing ever kicks the requeue list again: the request is stranded there while holding its tag. If it is the flush machinery's flush_rq, every subsequent fsync piles up in uninterruptible sleep and teardown hangs on tag draining. This matches a report of a lost PREFLUSH with ext4 on top of ublk after daemon crash recovery. ub->completion is an edge-triggered latch used as a proxy for the level condition "every queue has fetched all I/O commands", which can regress (F_BATCH's UNPREP, daemon death) and whose re-arm can be skipped. Drop it and wait on the real condition instead: the new helper ublk_wait_dev_ready_and_lock() waits on ublk_dev_ready() via wait_var_event_interruptible(), woken from ublk_mark_io_ready(), then re-checks it under ub->mutex, waiting again on regression, and returns with the mutex held and readiness guaranteed. Readiness becomes true in the same ub->mutex critical section that clears the last queue's ->canceling, so END_USER_RECOVERY marks the device LIVE and kicks the requeue list strictly after ->canceling clears. The wait stays interruptible, so a server whose daemon died can still be signalled out. For ublk_ctrl_start_dev() this replaces the fail-fast -EINVAL on an F_BATCH ready->UNPREP regression with waiting until the device is ready again. | ||||
