| CVE-2026-74266 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net/sched: sch_dualpi2: Do not call qdisc_tree_reduce_backlog during peek before restoring qlen Whenever dualpi2 drops packets during peek, it calls qdisc_tree_reduce_backlog. An issue arises because it calls qdisc_tree_reduce_backlog before it reincrements the qlen. If qlen drops to zero, but peek returns an skb, the parent's qlen_notify callback will be executed even though dualpi2 still has 1 packet on the queue and, thus, mistakenly deactivates the parent's class which leads to a null-ptr-deref: [ 101.427314][ T599] Oops: general protection fault, probably for non-canonical address 0xdffffc0000000009: 0000 [#1] SMP KASAN NOPTI [ 101.427755][ T599] KASAN: null-ptr-deref in range [0x0000000000000048-0x000000000000004f] [ 101.428048][ T599] CPU: 2 UID: 0 PID: 599 Comm: ping Not tainted 7.1.0-rc5-00284-gbce53c430ed7 #102 PREEMPT(full) [ 101.428400][ T599] Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 [ 101.428608][ T599] RIP: 0010:qfq_dequeue (net/sched/sch_qfq.c:1150) sch_qfq [ 101.428821][ T599] Code: 00 fc ff df 80 3c 02 00 0f 85 46 0c 00 00 4c 8d 73 48 48 89 9d b8 02 00 00 48 b8 00 00 00 00 00 fc ff df 4c 89 f2 48 c1 ea 03 <80> 3c 02 00 0f 85 2d 0c 00 00 48 b8 00 00 00 00 00 fc ff df 4c 8b All code [ 101.429348][ T599] RSP: 0018:ffff8881110df4f0 EFLAGS: 00010216 [ 101.429541][ T599] RAX: dffffc0000000000 RBX: 0000000000000000 RCX: dffffc0000000000 [ 101.429763][ T599] RDX: 0000000000000009 RSI: 00000024c0000000 RDI: ffff88811436c2b0 [ 101.429985][ T599] RBP: ffff88811436c000 R08: ffff88811436c280 R09: 1ffff11021277523 [ 101.430206][ T599] R10: 1ffff11021277526 R11: 1ffff11021277527 R12: 00000024c0000000 [ 101.430423][ T599] R13: ffff88811436c2b8 R14: 0000000000000048 R15: 0000000020000000 [ 101.430642][ T599] FS: 00007f61813e1c40(0000) GS:ffff8881691ef000(0000) knlGS:0000000000000000 [ 101.430913][ T599] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 101.431100][ T599] CR2: 00005651650850a8 CR3: 000000010ca0b000 CR4: 0000000000750ef0 [ 101.431320][ T599] PKRU: 55555554 [ 101.431433][ T599] Call Trace: [ 101.431544][ T599] <TASK> [ 101.431628][ T599] __qdisc_run (net/sched/sch_generic.c:322 net/sched/sch_generic.c:427 net/sched/sch_generic.c:445) [ 101.431792][ T599] ? dev_qdisc_enqueue (./include/trace/events/qdisc.h:49 (discriminator 22) net/core/dev.c:4176 (discriminator 22)) [ 101.431941][ T599] __dev_queue_xmit (./include/net/pkt_sched.h:120 ./include/net/pkt_sched.h:117 net/core/dev.c:4292 net/core/dev.c:4831) Fix this by only calling qdisc_tree_reduce_backlog in peek after the qlen is restored. | ||||
| CVE-2026-74265 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: mana: initialize gdma queue id to INVALID_QUEUE_ID mana_gd_create_mana_wq_cq() leaves queue->id as 0 (from kzalloc_obj()) until mana_create_wq_obj() assigns the firmware-returned id. If creation fails before that, cleanup calls mana_gd_destroy_cq() with id 0, NULLing gc->cq_table[0] and silently breaking whichever real CQ owns that slot. Initialize queue->id to INVALID_QUEUE_ID right after allocation, matching mana_gd_create_eq(). The existing (id >= max_num_cqs) guard then short-circuits cleanly. | ||||
| CVE-2026-74263 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: wwan: t7xx: check skb_clone in control TX t7xx_port_ctrl_tx() clones each skb fragment before passing it to the port transmit path. The clone is used immediately to set cloned->len, so an skb_clone() failure results in a NULL pointer dereference. Check the clone before using it. If previous fragments were already queued, preserve the driver's existing partial-write behavior by returning the number of bytes submitted so far. | ||||

| CVE-2026-72484 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: staging: most: video: avoid double free on video register failure comp_register_videodev() allocates a video_device with video_device_alloc() and releases it if video_register_device() fails. This can double free the video_device when __video_register_device() reaches device_register() and that call fails: video_register_device() -> __video_register_device() -> device_register() fails -> put_device(&vdev->dev) -> v4l2_device_release() -> vdev->release(vdev) -> video_device_release(vdev) comp_register_videodev() -> video_device_release(mdev->vdev) Use video_device_release_empty() while registering the device so that registration failure paths do not free mdev->vdev through vdev->release(). comp_register_videodev() then releases mdev->vdev exactly once on failure. Restore video_device_release() after successful registration so the registered device keeps its normal lifetime handling. This issue was found by a static analysis tool I am developing. | ||||
| CVE-2026-72481 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| 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. | ||||
| CVE-2026-72479 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: iio: accel: mma8452: handle I2C read error(s) in mma8452_read() Currently, If i2c_smbus_read_i2c_block_data() fails but mma8452_set_runtime_pm_state() succeeds, mma8452_read() returns 0. As a result, the caller mma8452_read_raw() assumes the read was successful and proceeds to use a buffer containing uninitialized stack memory. Add proper checking of the I2C read return value and propagate errors to the caller. | ||||
| CVE-2026-72475 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: dmaengine: dma-axi-dmac: Properly free struct axi_dmac_desc Use axi_dmac_free_desc() to free fully the descriptor at fail path when call axi_dmac_alloc_desc() in axi_dmac_prep_peripheral_dma_vec(). | ||||
| CVE-2026-72474 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: dmaengine: dma-axi-dmac: use DMA pool to manange DMA descriptor For architectures like Microblaze or arm64 (where this IP is used), DMA_DIRECT_REMAP is set which means that dma_alloc_coherent() might remap (and hence vmalloc()) some memory. This became visible in a design where dma_direct_use_pool() is not possible. With the above, when calling dma_free_coherent(), vunmap() would be called from softirq context and thus leading to a BUG(). To fix it, use a dma pool that is allocated in .device_alloc_chan_resources() and allocate blocks from it. The key point is that now dma_pool_free() is used in axi_dmac_free_desc() to free the blocks and that just frees the blocks from the pool in the sense they can be used again. In other words, no actual call to dma_free_coherent() happens. That only happens when destroying the pool in axi_dmac_free_chan_resources() which does not happen in any interrupt context. | ||||
| CVE-2026-72468 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Initialize re_id before removal registration rpcrdma_create_id() registers ep->re_rn with the rpcrdma ib_client before returning the new rdma_cm_id to rpcrdma_ep_create(). However rpcrdma_ep_create() currently stores that pointer in ep->re_id only after rpcrdma_create_id() returns. A local administrator can race an NFS/RDMA mount against RDMA device removal. If rpcrdma_remove_one() observes the just-registered notification before rpcrdma_ep_create() assigns ep->re_id, rpcrdma_ep_removal_done() calls trace_xprtrdma_device_removal(NULL). The tracepoint dereferences id->device->name and copies id->route.addr.dst_addr, so the callback can crash the kernel with a NULL pointer dereference. Store the rdma_cm_id in ep->re_id immediately before publishing ep->re_rn. The existing error path still destroys the id directly if registration fails; ep is then freed by the caller without using ep->re_id. Remove the later duplicate assignment in rpcrdma_ep_create(). | ||||
| CVE-2026-72467 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Check frwr_wp_create() during connect frwr_wp_create() creates the singleton Memory Region used to encode padding for Write chunks whose payload length is not XDR-aligned. Its failure paths return a negative errno and leave ep->re_write_pad_mr set to NULL. rpcrdma_xprt_connect() currently ignores that return value. If frwr_wp_create() fails after the rest of the connection setup succeeds, xprt_rdma_connect_worker() treats the connection attempt as successful and sets XPRT_CONNECTED. A later NFS/RDMA read with a non-4-byte-aligned receive page length reaches rpcrdma_encode_write_list(), passes the NULL write-pad MR to encode_rdma_segment(), and dereferences it. This is locally triggerable on an NFS/RDMA client after a connect or reconnect hits a local MR allocation, DMA-map, MR-map, or post-send failure; a remote peer alone cannot force the local MR setup failure. Check the return value and fail the connect as -ENOTCONN, matching the adjacent setup failures. This keeps XPRT_CONNECTED clear and lets the normal reconnect path retry. | ||||

| CVE-2026-72457 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: apparmor: fail policy unpack on accept2 allocation failure unpack_pdb() may need to allocate a missing ACCEPT2 table for older policy data. If that allocation failed, it set an error message but jumped to the success path, returning a policydb with the required table missing. Return -ENOMEM through the normal failure path when the ACCEPT2 allocation fails. Remove the now-unused out label. | ||||
| CVE-2026-72453 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: regcache: Do not overwrite error code when finalizing cache after error During regcache initialization, if an error occurs in the cache_ops->populate callback, and if cache operations include an exit callback, the error code from populate() is overwritten with the return value from exit(). This hides the error condition from the caller of regcache_init(), and can cause NULL pointer dereferences when the regcache is later accessed. | ||||
| CVE-2026-72448 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: Fix leak of SQ timestamp buffer on teardown The send-queue timestamp ring is allocated with qmem_alloc() when timestamping is used, but otx2_free_sq_res() never freed sq->timestamps, leaking that memory across ifdown and device removal. Add the missing qmem_free() alongside the other SQ companion buffers. | ||||
| CVE-2026-72447 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: sctp: hold socket lock when dumping endpoints in sctp_diag SCTP_DIAG endpoint dumping was traversing endpoint address lists without holding lock_sock(), while those lists could change concurrently via socket operations (e.g., bindx changes). This creates a race where nla_reserve() counts addresses under RCU protection, but the subsequent copy may see fewer entries, potentially leaking uninitialized memory to userspace. Fix this by: - Taking a reference on each endpoint during hash traversal - Moving socket operations (lock_sock()) outside read_lock_bh() - Serializing address list access during dump - Reworking sctp_for_each_endpoint() to support restart-based traversal with (net, pos) tracking Also: - Add WARN_ON_ONCE() for inconsistent address counts - Fix idiag_states filtering for LISTEN vs association cases - Skip dumping endpoints being freed (ep->base.dead) - Move dump position tracking into iterator, removing cb->args[4] and its comment for sctp_ep_dump()., - Update the comment for cb->args[4] and remove the comment for unused cb->args[5] for sctp_sock_dump(). Note: traversal is restart-based and may re-scan buckets multiple times, but this is acceptable due to small bucket sizes and required to support sleeping-safe callbacks. This issue was reported by Nico Yip (@_cyeaa_) working with TrendAI Zero Day Initiative. | ||||
| CVE-2026-72443 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Kill MIDI 2.0 URBs before freeing endpoints MIDI 2.0 input URBs are started during snd_usb_midi_v2_create(). A later setup failure can still jump to snd_usb_midi_v2_free(), which currently frees each endpoint and its coherent URB buffers without first stopping the submitted URBs. A completion can then dereference the embedded URB context and endpoint state after they have been freed, or try to resubmit from the stale endpoint. This was observed as a KASAN slab-use-after-free in input_urb_complete(). The buggy scenario involves two paths, with each column showing the order within that path: probe error path: USB completion path: 1. start_input_streams() submits 1. The HCD still owns a input URBs. submitted input URB. 2. A later setup helper returns 2. input_urb_complete() runs an error. with urb->context in ep. 3. snd_usb_midi_v2_free() frees 3. The completion reads ep endpoint storage and URB buffers. state and can requeue URBs. Make the endpoint destructor follow the same teardown ordering used for disconnect when the endpoint has not already been disconnected: publish ep->disconnected, kill the URBs synchronously, and drain the endpoint before freeing URB buffers and endpoint storage. The guard avoids repeating the stop sequence after the normal snd_usb_midi_v2_disconnect_all() path, while still synchronizing the direct MIDI 2.0 create-error free path.

| In the Linux kernel, the following vulnerability has been resolved: ieee802154: fix kernel-infoleak in dgram_recvmsg() KMSAN reported a kernel-infoleak in move_addr_to_user(): BUG: KMSAN: kernel-infoleak in instrument_copy_to_user include/linux/instrumented.h:131 [inline] BUG: KMSAN: kernel-infoleak in _inline_copy_to_user include/linux/uaccess.h:205 [inline] BUG: KMSAN: kernel-infoleak in _copy_to_user+0xcc/0x120 lib/usercopy.c:26 instrument_copy_to_user include/linux/instrumented.h:131 [inline] _inline_copy_to_user include/linux/uaccess.h:205 [inline] _copy_to_user+0xcc/0x120 lib/usercopy.c:26 copy_to_user include/linux/uaccess.h:236 [inline] move_addr_to_user+0x2e7/0x440 net/socket.c:302 ____sys_recvmsg+0x232/0x610 net/socket.c:2925 ...

The execution flow is as follows: 1. `__ieee802154_rx_handle_packet()` declares a local `struct ieee802154_hdr hdr` on the stack. 2. `ieee802154_hdr_pull()` calls `ieee802154_hdr_get_addr()` to parse the source and destination addresses into this structure. 3. If the address mode is `IEEE802154_ADDR_NONE`, `ieee802154_hdr_get_addr()` previously only set the `mode` field, leaving the `pan_id` field containing uninitialized stack memory. 4. This uninitialized `pan_id` is later copied into a `struct sockaddr_ieee802154` in `dgram_recvmsg()` via `ieee802154_addr_to_sa()`. 5. Finally, `move_addr_to_user()` copies the socket address structure to user space, leaking the uninitialized bytes. Fix this by using `memset` to zero out the address structure in `ieee802154_hdr_get_addr()` when the mode is `IEEE802154_ADDR_NONE`. | ||||

| In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix writes_pending leak on write request failures raid10_make_request() acquires a writes_pending reference with md_write_start() before dispatching write requests. Several failure paths in raid10_write_request() complete the bio and return without reaching the normal write completion path, causing the corresponding md_write_end() to be skipped.
