| CVE-2026-90407 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.7 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix overreads in ath11k_wmi_process_csa_switch_count_event() There is no policy entry for WMI_TAG_PDEV_CSA_SWITCH_COUNT_STATUS_EVENT, so the parse infrastructure does not enforce a minimum length for the event struct. Additionally, the num_vdevs field is taken directly from firmware and used as a loop bound over the vdev_ids array without checking that it fits within the TLV payload. Either condition can cause an out-of-bounds read. Add a TLV policy entry for WMI_TAG_PDEV_CSA_SWITCH_COUNT_STATUS_EVENT so the parse infrastructure enforces a minimum length for the fixed-size event struct. Add a helper ath11k_wmi_tlv_data_len() to recover the payload length of a parsed TLV from the header preceding its data pointer. Use it in ath11k_wmi_process_csa_switch_count_event() to bound num_vdevs before the loop. Compile tested only. | ||||

| In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix stride mismatch in mac_phy_caps_parse() Currently, in ath11k_wmi_tlv_mac_phy_caps_parse(), kcalloc() sizes the mac_phy_caps buffer as tot_phy_id * len, where len is clamped to min(firmware_len, sizeof(struct wmi_mac_phy_capabilities)). The subsequent memcpy() destination advances by sizeof(full struct) per slot via C pointer arithmetic, not by the clamped len. When firmware sends short TLVs, the second and later slots are written past the end of the allocation. The reader in ath11k_pull_mac_phy_cap_svc_ready_ext() also indexes the buffer with full-struct pointer arithmetic, so the allocation must match that stride. Fix by using kzalloc_objs(), which derives the element size from the pointer type, making allocation size and pointer stride provably consistent regardless of what len the firmware provides. Compile tested only. | ||||
| CVE-2026-90392 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Fix potential UAF when reading bpf link info In bpf_link_show_fdinfo and bpf_link_get_info_by_fd, link->prog is accessed without holding any locks. If the prog is concurrently replaced via bpf_link_update, the old prog can be freed, leading to a potential UAF issue. Fix this by accessing link->prog under RCU protection to safely fetch the pointer and guarantee its lifetime while reading its fields. | ||||
| CVE-2026-90385 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: md/raid1: create serial pool adding rdev to array with serialize_policy=1 The following bug has been observed with kernel 7.1.3 after adding a new rdev to an existing RAID1 array with serialize_policy enabled: Oops: 0002 [#1] CPU: 0 UID: 0 PID: 19639 Comm: ext4lazyinit Not tainted 7.1.3-1-default RIP: _raw_spin_lock_irqsave+0x27/0x50 CR2: 0000000000004960 Call Trace: wait_for_serialization+0xb9/0x260 [raid1] raid1_make_request+0x762/0xaff [raid1] md_handle_request+0x1c9/0x2e0 [md_mod] The raid1.c code calls wait_for_serialization() if the MD_SERIALIZE_POLICY is set, and wait_for_serialization assumes that rdev->serial is initialized. Normally this will be the case for arrays that have the serialize_policy sysfs attribute set to 1. But when a new rdev is added to an existing array in bind_rdev_to_array(), the condition at mddev_create_serial_pool() causes creation of rdev->serial to be skipped. Fix it. | ||||
| CVE-2026-90383 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: misc: sgi-gru: remove interrupt-context page-table walks The GRU TLB miss handler walks a process's page tables without holding page-table locks or a reference to the mapped page. It also uses a kernel page-table accessor on user page tables and supports only PMD-level large mappings on x86-64. Remove the direct walker. Send interrupt faults directly to user polling mode so the existing call-OS fallback retries them in process context. Remove the mmap-lock failure statistic that can no longer be incremented. | ||||
| CVE-2026-90375 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: fix non-AQL packet accounting for MLO stations __mt76_tx_queue_skb() overrides the wcid passed by the driver with sta->drv_priv, so the wcid might incorrectly be changed after TX, causing wcid->non_aql_packets to be counted on the wrong wcid. For example, on the AP side, if a station's setup link is the 5G link and the station uses 2G to transmit a frame, the value of non_aql_packets is increased on the 5G wcid but decreased on the 2G wcid. Once the inflated counter exceeds MT_MAX_NON_AQL_PKT, the TX scheduler permanently refuses to service the station. Drop the reassignment and account on the wcid used for transmission. This also records the actual wcid in the queue entry. | ||||
| CVE-2026-90368 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: unwind state on add_interface failure When mt76_wcid_alloc() fails, mt7915_add_interface() returned without clearing the vif_mask/omac_mask bits it had already set, without removing the firmware dev info added earlier, and without clearing a monitor_vif pointer to the vif mac80211 is about to free. mac80211 does not call remove_interface() for a failed add, so the indices and firmware dev entry leaked permanently and testmode could dereference the stale monitor_vif. Add a proper error unwind. | ||||
| CVE-2026-90365 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: cancel reset and rc work on device unregister Both drivers cancelled dump_work on unregister but left reset_work and rc_work to be flushed only by destroy_workqueue() in mt76_free_device(), which runs after the hw is unregistered and the hardware stopped. A reset_work that fires in that window calls ieee80211_restart_hw() and re-arms mac_work on an unregistered hw, and rc_work touches station state being torn down. Cancel both up front, alongside dump_work. | ||||
| CVE-2026-90358 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf, x86: Fix trampoline stack size for 128-bit arguments btf_distill_func_proto() accepts a function argument up to 16 bytes, so a 128-bit scalar such as __int128 reaches the x86 trampoline with arg_size == 16. But the current implementation assumes an __int128 argument only needs one register, so the register save area is under-allocated and save_args() overwrites adjacent stack slots. Compute the register count from arg_size for all arguments to fix it. | ||||
| CVE-2026-90347 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: arm64: ptrace: Keep 'orig_x0' in-sync with x0 on syscall entry Commit e057b9477232 ("arm64: syscall: Ensure saved x0 is kept in-sync with tracer updates") attempted to resolve a long-standing issue with syscall entry tracing, where a tracer is able to manipulate the first syscall argument without being subjected to seccomp or audit checking. Unfortunately, that fix was incomplete [1], as it failed to update 'orig_x0' between a tracer updating x0 during a seccomp ptrace exit (SECCOMP_RET_TRACE) and the seccomp filter being re-evaluated. Rather than add hooks to the core seccomp code, instead move the synchronisation code into the ptrace GPR and syscall setting code so that 'orig_x0' is kept up to date with x0 whenever we're stopped on the syscall entry path. | ||||
| CVE-2026-90346 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: clean up color-change beacon data on errors nl80211_color_change() calls nl80211_parse_beacon() for the beacon_next template, which can allocate params.beacon_next.mbssid_ies and .rnr_ies. A parsing failure returned directly instead of using the out: cleanup, leaking any allocations completed before the error. Allocate the nested attribute table before parsing beacon_next. Its allocation failure can then return before beacon data exists, while a later parsing failure uses out: to release the parsed data. | ||||
| CVE-2026-90345 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: fix P2P action frame handling without device vif Some P2P action frame paths assume the P2P device vif is always available. That is not true when userspace sends non-P2P public action frames through the primary interface, or when action-frame abort runs after the P2P device vif has not been created. Fall back to the primary vif when aborting an action frame without a P2P device vif, and guard P2P device saved IE access before using it for peer channel search. | ||||
| CVE-2026-90343 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: stop PMSR before P2P and NAN teardown PMSR request teardown must abort active measurements while the wireless_dev is still present in the driver. cfg80211_leave_locked() and cfg80211_stop_pd() already do this before invoking the driver's stop callback, but cfg80211_stop_p2p_device() and cfg80211_stop_nan() do not. Those helpers are also called directly by nl80211, rfkill shutdown, and wireless_dev unregister paths. If one of these paths stops a P2P device or NAN interface with a pending request, it removes the mac80211 subinterface from the driver first. Subsequent request cleanup cannot reach the lower driver's abort callback, but cfg80211 frees the request regardless. Driver state can then retain a stale request and use it when it later reports a result. Call cfg80211_pmsr_wdev_down() before stopping the P2P device or NAN interface. This keeps lower-driver request state and cfg80211 request ownership in sync for all of the helpers' callers. | ||||
| CVE-2026-90337 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: serial: core: do fallible allocations before the console can be registered serial_core_add_one_port() allocates uport->tty_groups after uart_configure_port(), which may register the console. If the allocation fails, the driver unwinds the port while its console remains registered. The earlier uport->name allocation has a related failure path that leaves state->uart_port linked to a port being freed. Failslab reproduced a NULL dereference in PL011 console output and a KASAN use-after-free in i.MX console output after failed binds. Allocate the name and tty_groups before linking the port and configuring it. Reserve space for the optional driver attribute group because config_port() may populate uport->attr_group during configuration. | ||||
| CVE-2026-90336 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: serial: core: clear freed pointers on uart_register_driver() failure uart_register_driver() leaves drv->state pointing to freed memory when tty_alloc_driver() fails. If tty_register_driver() fails, drv->tty_driver also retains a pointer after its reference is dropped. Drivers that use drv->state as an "already registered" flag can then skip registration on the next probe and pass the freed state to uart_add_one_port(). This issue was found with failslab on QEMU's raspi1ap board by failing registration and binding the PL011 port again. Clear both pointers on their failure paths, as uart_unregister_driver() already does. | ||||
| CVE-2026-90335 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: tty: skip cdev_del() when no cdev is registered TTY device registration can fail before a cdev is allocated. Serial core keeps the port so setserial can still use it, and later removal passes the NULL cdev slot to cdev_del(), causing a NULL-pointer dereference. Only delete the cdev when the slot is not NULL. | ||||
| CVE-2026-90330 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: HID: logitech-hidpp: Fix FF device cleanup on init failure hidpp_ff_init() creates the input force-feedback device with input_ff_create(), then allocates the HID++ FF private data, effect ID array, and workqueue. If any of those allocations fail after input_ff_create() succeeds, the function returns an error without destroying the FF device. Add an unwind path that frees the private allocations made by hidpp_ff_init() and calls input_ff_destroy() for failures after input_ff_create() succeeds. | ||||
| CVE-2026-90328 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: HID: steam: Reject short reads Steam Controller FEATURE reports encode the size of the message in the message itself. Previously we were trusting that the size reported matched the size we actually read, leading to a potential issue with short reads. Instead, we should actually verify the length of the read. | ||||
| CVE-2026-90322 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ocfs2/cluster: keep heartbeat local node stable o2nm_node_local_store() handles local=0 by stopping o2net and setting cl_local_node to O2NM_INVALID_NODE_NUM, but it leaves cl_has_local set. That stale state makes o2nm_this_node() return 255, blocks a later local=1 attempt with -EBUSY, and can feed 255 to heartbeat users that call o2nm_this_node() dynamically. Clearing cl_has_local is required when the local node is reset. But heartbeat threads can still be running at that point. They pin the local node config item at startup, yet o2hb_do_disk_heartbeat() and thread teardown re-read o2nm_this_node() for the local slot and for o2nm_undepend_this_node(). Once local=0 has cleared the live local-node state, those dynamic reads return O2NM_MAX_NODES, which is also the invalid node number 255. Store the local node number in the heartbeat region when the region starts. Use that stable node for heartbeat slot writes/checks, negotiation messages, and the final configfs undepend. Stop the heartbeat loop when the current local node no longer matches the stored node, and clear cl_has_local together with cl_local_node in the local=0 path so nodemanager state matches node removal.

| CVE-2026-90313 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: bpf, cgroup: Fix invalid storage access after __cgroup_bpf_attach failed A potential invalid storage access issue can occur after replacing a cgroup bpf prog. This occurs in the following scenario: 1. prog1 with storage is attached to a cgroup in multi-attach mode. 2. prog1 is replaced with prog2 using BPF_F_REPLACE in multi-attach mode, but fails midway (e.g. in bpf_trampoline_link_cgroup_shim or update_effective_progs). 3. A new prog3 is attached to the cgroup in multi-attach mode. The reason is that __cgroup_bpf_attach overwrites pl->storage with the new storage prior to attachment completion. When attachment fails midway, the cleanup path calls bpf_cgroup_storages_free(new_storage) to free the newly allocated storage, but fails to restore pl->storage back to old_storage. Consequently, the still-active prog1 holds invalid or dangling storage pointers, leading to an invalid memory access when prog1 executes and calls bpf_get_local_storage. Additionally, original pl->flags and cgrp->bpf.flags[atype] are left unrestored. Fix this by saving old_pl_flags, old_storage, and old_flags prior to the update, and properly restoring all of them in the cleanup path on error. | ||||
