| CVE-2026-97578 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: media: verisilicon: rockchip: guard VPU981 AV1 divisor and tile buffer rockchip_vpu981_av1_dec_set_tile_info() divides context_update_tile_id by tile_info->tile_cols and writes one descriptor per tile into the tile_info DMA buffer, which holds AV1_MAX_TILES entries; tile_cols and tile_rows come from the bitstream. Guard the division against a zero tile_cols by initialising the context-update values to zero and computing them only when tile_cols is non-zero, and stop the descriptor writes once the tile_info buffer is full. The tile geometry written to the hardware registers is left unmodified; the per-dimension and total tile bounds are enforced by the control validation. | ||||
| CVE-2026-97577 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: media: verisilicon: rockchip: reject AV1 frames exceeding the tile capacity rockchip_vpu981_av1_dec_set_tile_info() indexes the tile group entry array by tile1 * tile_cols + tile0, reading up to tile_cols * tile_rows entries, lays out one descriptor per tile in the AV1_MAX_TILES tile_info buffer, and programs the real tile_cols / tile_rows into the hardware. The tile group entry control is a dynamic array sized to the number of entries userspace submitted, independent of tile_cols / tile_rows, so a frame that claims more tiles than entries reads past the array. A frame that claims more than AV1_MAX_TILES tiles also leaves the hardware programmed for more tiles than the descriptor buffer holds. Reject both in prepare_run(): tile_cols * tile_rows must not exceed the submitted entry count or AV1_MAX_TILES. The entry count is read via v4l2_ctrl_find() (ctrl->elems). This mirrors the bound the mediatek AV1 decoder already enforces. | ||||
| CVE-2026-97576 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: media: v4l2-ctrls: validate HEVC tile counts The stateless HEVC decoders read num_tile_columns_minus1 + 1 entries from column_width_minus1[] and num_tile_rows_minus1 + 1 from row_height_minus1[] and use them as tile-loop bounds, but std_validate_compound() does not bound these u8 counts. Reject a V4L2_CTRL_TYPE_HEVC_PPS with tiling enabled whose tile counts exceed the uAPI array capacity, mirroring the existing compound-control range checks. | ||||
| CVE-2026-97575 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: media: v4l2-ctrls: validate AV1 tile counts The stateless AV1 decoders use tile_info.tile_cols and tile_rows as loop bounds and as indices into the mi_*_starts[] and *_in_sbs_minus_1[] arrays, as the divisor for context_update_tile_id, and their product bounds the per-tile descriptor buffers, but std_validate_compound() does not bound these u8 fields. Reject a V4L2_CTRL_TYPE_AV1_FRAME whose tile_cols or tile_rows exceeds V4L2_AV1_MAX_TILE_COLS / _ROWS, or whose product exceeds V4L2_AV1_MAX_TILE_COUNT. A zero tile count is left to the consuming driver so the zero-initialised control that existing userspace submits is still accepted. | ||||
| CVE-2026-97573 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 8.1 High |
| In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Handle buffer allocation failure in bnxt_rx_ring_reset() bnxt_rx_ring_reset() frees the ring buffers and then reallocates them, ignoring the result. bnxt_alloc_one_rx_ring() can fail in bnxt_alloc_one_tpa_info_data(), which returns -ENOMEM on the first failed allocation and leaves the remaining rxr->rx_tpa[] entries zeroed. The error isn't propagated up, so the loop in bnxt_rx_ring_reset continues and at the end the code re-enables TPA with partially unallocated rx_tpa array. This means that when the agg_id from hardware is mapped to a SW index in rxr->rx_tpa[], an uninitialized slot can be chosen which would hand a zero DMA address to the device. Fix this by falling back to a global reset, which is what the existing code already does when other functions fail, but unlike the other failure cases this particular failure has to return because TPA can't be re-enabled since the allocation failed. | ||||
| CVE-2026-97562 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: smb: client: pin DFS superblock in iterator callback tcon_super_cb() stores a raw superblock pointer, but __cifs_get_super() takes its active reference only after iterate_supers_type() has dropped s_umount and its passive reference. Concurrent DFS automount expiry can therefore free the superblock before cifs_sb_active() uses it. A deterministic KASAN test reproduces the race as: BUG: KASAN: slab-use-after-free in cifs_sb_active+0x77/0x80 The same test passes with this change applied. Take the active reference in the callback while iterate_supers_type() still holds s_umount shared. cifs_put_tcp_super() remains the matching release. | ||||
| CVE-2026-97524 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: mptcp: avoid unneeded actions on subflow reset Once in a blue moon, the mptcp receive path can recursively call mptcp_data_ready() via state change under unlucky error conditions, and then try to hold the data lock again. Break the recursion loop explicitly checking for the exceptional condition. Add a new flag instead of using an existing one like 'closing', to exit early in subflow_state_change(), and explicitly flush the RX queue at reset time. This avoids unneeded processing to check for available data -- calling get_mapping_status() and more on a dying subflow -- but also in error reporting and worker scheduling. Note that we must consume the currently peeked skb before invoking mptcp_dss_corruption to avoid consuming it again after the eventual reset has freed it. | ||||
| CVE-2026-97523 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: mptcp: close race between scheduler and state change The mptcp scheduler may race with subflow sockets state change: data transmission on the selected socket may fail and a later release could try to use mss_now reset to 0 for a divide operation. Address the issue by explicitly checking for the critical scenario. | ||||
| CVE-2026-97509 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Keep XDomain reference during the lifetime of a service This is needed because we release the service ID in tb_service_release() and the ID array is owned by the parent XDomain. | ||||
| CVE-2026-97508 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Set tb->root_switch to NULL when domain is stopped Similarly what we do with the firmware connection manager. This makes tb_xdp_handle_request() return error to the remote host. However, we need to make sure we keep the uuid alive so that we can reply until the whole domain is released. | ||||
| CVE-2026-97497 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check bounds for allocate_sdma_queue restore_sdma_id allocate_sdma_queue has an option where the sdma queue id can be specified (used by CRIU). We weren't bounds-checking that value. Confirm it's less than the maximum number of queues. | ||||
| CVE-2026-97496 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix OOB memory exposure in get_wave_state() The get_wave_state() function for v9 trusts cp_hqd_cntl_stack_size and cp_hqd_cntl_stack_offset values read directly from the MQD, which are written by GPU microcode and fully attacker-controlled on the CRIU-restore path (via AMDKFD_IOC_RESTORE_PROCESS with H3). this leads to an unbounded copy_to_user() that can leak adjacent GTT/kernel memory. If offset > size, integer underflow produces a ~4 GiB read length, if size is set to 1 MiB against a 4 KiB allocation, we leak 1 MiB of adjacent kernel memory (other queues' MQDs, ring buffers, KASLR pointers). Fix by clamping both cp_hqd_cntl_stack_size to the actual allocated buffer size (q->ctl_stack_size) and cp_hqd_cntl_stack_offset to the clamped size before performing arithmetic and copy_to_user(). This ensures we never read beyond the allocated kernel BO regardless of attacker-supplied MQD field values. | ||||
| CVE-2026-97495 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check bounds on allocate_doorbell allocated_doorbell has an option to set the doorbell id to a specific value (used by CRIU). This value was not bounds checked. Check to confirm it's less than KFD_MAX_NUM_OF_QUEUES_PER_PROCESS. | ||||
| CVE-2026-97476 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: rds: filter RDS_INFO_* getsockopt by caller's netns The RDS_INFO_* family of getsockopt(2) options reads several file-scope global lists that are not per-netns: rds_sock_info / rds6_sock_info, rds_sock_inc_info / rds6_sock_inc_info -> rds_sock_list rds_tcp_tc_info / rds6_tcp_tc_info -> rds_tcp_tc_list rds_conn_info / rds6_conn_info, rds_conn_message_info_cmn (for the *_SEND_MESSAGES and *_RETRANS_MESSAGES variants), rds_for_each_conn_info (for RDS_INFO_IB_CONNECTIONS) -> rds_conn_hash[] The handlers do not filter by the caller's network namespace. rds_info_getsockopt() has no netns or capable() check, and rds_create() has no capable() check, so AF_RDS is reachable from an unprivileged user namespace. As a result, an unprivileged caller in a fresh user_ns plus netns can read the bound address and sock inode of every RDS socket on the host, the peer address of incoming messages on every RDS socket on the host, the peer address and TCP sequence numbers of every rds-tcp connection on the host, and the peer address and RDS sequence numbers of every RDS connection on the host. The rds-tcp transport is reachable from a non-initial netns (see rds_set_transport()), so a one-shot init_net gate at rds_info_getsockopt() would deny legitimate per-netns visibility to rds-tcp callers. Instead, filter at each handler by comparing the netns of the caller's socket to the netns of the list entry, or to rds_conn_net(conn) for connection paths. Only copy entries whose netns matches the caller. Counters (RDS_INFO_COUNTERS) are aggregate statistics and remain global. Reproducer (KASAN VM, rds and rds_tcp loaded): an AF_RDS socket binds 127.0.0.1:4242 in init_net as root. A child process enters a fresh user_ns plus netns and opens AF_RDS there, then calls getsockopt(SOL_RDS, RDS_INFO_SOCKETS). Before this change, the child sees the init_net socket. After this change, the child sees zero entries. Drop the rds_sock_count, rds_tcp_tc_count, and rds6_tcp_tc_count globals. v2 used them for the size precheck and lens->nr; v3 replaced the precheck with a per-ns count from a first pass over the list, so the globals have no remaining readers. The matching increments and decrements in rds_create()/rds_destroy_sock() and rds_tcp_set_callbacks()/rds_tcp_restore_callbacks() go away with them. Reported by the kernel test robot under clang W=1. | ||||
