| CVE-2026-97529 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Validate BSG request_len before reading vendor_cmd[] The FC BSG transport allocates job->request via memdup_user() using the exact user-supplied request_len. For FC_BSG_HST_VENDOR, fc_bsg_host_dispatch() only guarantees request_len covers msgcode and vendor_id; it does not account for the vendor_cmd[] flexible array. qla2xxx then reads the command selector vendor_cmd[0] and, in several sub-handlers, vendor_cmd[1]/[2] or structures overlaid on the vendor command area without verifying request_len. A caller holding CAP_SYS_RAWIO can submit a short request whose vendor_id matches the host, triggering out-of-bounds heap reads (KASAN-detectable, and able to mis-select a command or panic). Add a central guard in qla2x00_process_vendor_specific() so the selector is always in bounds, restrict the early vendor_cmd[0] read in qla24xx_bsg_request() to sufficiently long vendor messages, and add request_len checks to the sub-handlers that read further: qla24xx_proc_fcp_prio_cfg_cmd(), qla2x00_process_loopback(), qla84xx_reset(), qla84xx_updatefw(), qla2x00_read_optrom(), qla2x00_update_optrom(), qlafx00_mgmt_cmd() and qla28xx_validate_flash_image(). | ||||
| CVE-2026-97518 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: reject duplicate wiphy cipher suite entries Duplicate entries in wiphy->cipher_suites do not describe any additional capability, but cfg80211 currently accepts them and leaves individual consumers to deal with them. One such consumer is the WEXT compatibility code, which appends a WEP key length for each WEP cipher entry it sees. Repeated WEP entries can therefore overflow the fixed iw_range::encoding_size array returned by SIOCGIWRANGE. Reject duplicate cipher suite entries in wiphy_register() instead. This keeps the cipher suite invariant in one place and makes malformed wiphy descriptions fail early with -EINVAL, rather than relying on a single cfg80211 user to handle duplicates correctly. | ||||
| CVE-2026-97505 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: PCI/sysfs: Add CAP_SYS_ADMIN check to __resource_resize_store() Currently, the __resource_resize_store() allows writing to the resourceN_resize sysfs attribute to change a BAR's size without checking for capabilities, currently relying only on the file access check. Resizing a BAR modifies PCI device configuration and can disrupt active drivers. After the upcoming conversion to static attributes, it will also trigger resource file updates via sysfs_update_groups(). Add a CAP_SYS_ADMIN check to prevent unprivileged users from performing BAR resize operations. | ||||
| CVE-2026-97494 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: validate and share PSP fw_pri_buf copies via psp_copy_fw Change psp_copy_fw from void to int: return -ENODEV when drm_dev_enter fails, and -EINVAL when the image size is zero or larger than the 1 MiB PSP private buffer. Replace open-coded memset/memcpy into fw_pri_buf with psp_copy_fw. | ||||
| CVE-2026-97428 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 7.7 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: harden FRU PIA parsing with bounded helpers Replace the open-coded TLV walk with fru_pia_advance() and fru_pia_copy_field() helpers that bound every read by the actual EEPROM data length, preventing out-of-bounds reads on truncated or malformed FRU data. | ||||
| CVE-2026-97424 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/ras: add ras_suspend callback and use it for cp_ecc_error_irq cp_ecc_error_irq is acquired in amdgpu_gfx_ras_late_init() but released in gfx_v9_0_hw_fini(), so the put site has to query amdgpu_irq_enabled() because the get is skipped on SR-IOV VF. ras_late_init / ras_fini have no suspend counterpart, so move the put to amdgpu_gfx_ras_suspend() / amdgpu_gfx_ras_fini() and add a matching ras_suspend callback that is invoked from amdgpu_ras_suspend() before disable_all_features(). The get and put now sit in the same place and check the same condition (not VF, funcs registered), no refcount querying needed. An active flag gates ras_fini so the suspend-then-unload-without-resume path falls into amdgpu_ras_block_late_fini_default() instead of double-releasing what ras_suspend already cleaned up. Drop the cp_ecc_error_irq put from gfx_v9_0_hw_fini(). gfx_v8_0 manages cp_ecc_error_irq locally and is unaffected; no other GFX generation has this IRQ. | ||||
| CVE-2026-93793 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: validate TX_CMD response layout TX_CMD parsing uses frame_count to walk status entries and then read the trailing SCD SSN. Make the minimum-length check follow that exact runtime layout calculation before parsing the payload. For new TX API, reject TX_CMD responses with frame_count != 1 and warn/return in the aggregation handler to document that aggregated accounting is expected via BA notifications. | ||||
| CVE-2026-93272 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: remoteproc: qcom_wcnss: Fix handling the lack of PD regulators in v3 The changes introduced to handle single power domain platforms have swapped the info pointer increment from num_pd_vregs to num_pds, which would shift the info pointer past the end of the array for pronto-v3, which does not list power domain regulators in vregs. This showed up as a difference between GCC- and LLVM-compiled kernels on SDM632 devices, where only with LLVM one would get the "regulator request with no identifier" error, because the out-of-bounds memory ended up being zeroed. Fix by skipping the increment when there are more power domains than regulators. | ||||

| In the Linux kernel, the following vulnerability has been resolved: drm/sysfb: simpledrm: Improve stride validation Validate the computed stride against the maximum value INT_MAX. | ||||
| CVE-2026-93221 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 8.1 High |
| In the Linux kernel, the following vulnerability has been resolved: nfsd: convert nfsd_net boolean flags to unsigned long flags word nfsd_net contains several boolean fields that are accessed from concurrent contexts without serialization. In particular, nfsd4_end_grace() guards its drain path with a plain bool: if (nn->grace_ended) return; nn->grace_ended = true; The read and the write are independent, and nothing in struct nfsd_net serializes them. At least two contexts can reach this code with no lock held: laundromat path laundry_wq kworker nfs4_laundromat() nfsd4_end_grace() RECLAIM_COMPLETE path nfsd compound kthread nfsd4_reclaim_complete() inc_reclaim_complete() nfsd4_end_grace() Both callers can observe grace_ended == false on different CPUs, both store true, and both proceed into nfsd4_record_grace_done(), which invokes the active client_tracking_ops->grace_done callback. For tracking ops that drain reclaim_str_hashtbl (legacy_tracking_ops via nfsd4_recdir_purge_old, and the cld v1+ ops via nfsd4_cld_grace_done), grace_done calls nfs4_release_reclaim(), which walks every bucket of reclaim_str_hashtbl with no lock and calls nfs4_remove_reclaim_record() (list_del + kfree) on each entry. Two concurrent walkers corrupt the list and double-free every nfs4_client_reclaim. A concurrent nfsd4_find_reclaim_client() iterating the same bucket reads through freed memory. A third call site exists in nfs4_state_start_net() on the skip_grace startup path, but it runs under nfsd_mutex before any client has connected and before the laundromat's first delayed work fires, so it cannot race with the two callers above. Replace the scattered boolean fields in nfsd_net with a single unsigned long flags word and an enum nfsd_net_flag for the bit positions. The grace_ended race is fixed by using test_and_set_bit(), which is atomic on all architectures. The remaining flags (grace_end_forced, in_grace, somebody_reclaimed, track_reclaim_completes, nfsd_net_up, lockd_up) are converted to use test_bit/set_bit/clear_bit for consistency. This avoids sub-word cmpxchg issues on architectures like Hexagon that only support word-sized atomic operations. | ||||
| CVE-2026-93202 | 1 Linux | 1 Linux Kernel | 2026-10-21 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: i3c: master: Fix recursive locking during device registration i3c_master_register_new_i3c_devs() registers newly discovered devices while holding i3c_bus_normaluse_lock(), a down_read(). device_register() can immediately probe the device, and probe callbacks typically invoke I3C helpers that take i3c_bus_normaluse_lock() again, leading to a recursive acquisition of the same rwsem. rwsems do not support recursive read locking and can deadlock when a writer is waiting. See the "Recursive read locks" section of Documentation/locking/lockdep-design.rst. For example, with Intel LPSS I3C, LOCKDEP generates a WARNING like: # echo intel-lpss-i3c.0 > /sys/bus/platform/drivers/mipi-i3c-hci/unbind # echo intel-lpss-i3c.0 > /sys/bus/platform/drivers/mipi-i3c-hci/bind WARNING: possible recursive locking detected kworker/5:1/94 is trying to acquire lock: ffff88811c810d78 (&i3cbus->lock){++++}-{4:4}, at: i3c_device_match_id+0x45/0x370 but task is already holding lock: ffff88811c810d78 (&i3cbus->lock){++++}-{4:4}, at: i3c_master_reg_work_fn+0x21/0x5f0 Fix this by separating device creation from device registration. Populate desc->dev under the maintenance lock, collect the devices that still need registration into a local list, then release the lock before calling device_register(). Finally retake the lock and clean up any devices that failed to register. Use the maintenance lock rather than the normal-use lock while adding device objects. A write-side maintenance lock prevents readers from observing a partially initialized desc->dev during initial device population, or desc->dev disappearing if registration fails. The local list requires a list node, so add a list node member to struct i3c_device. | ||||
| CVE-2026-93186 | 1 Linux | 1 Linux Kernel | 2026-10-21 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: cxl/mbox: Clamp mailbox output allocation to the payload size CXL_MEM_SEND_COMMAND bounds the user's in.size to the mailbox payload size but leaves out.size unbounded, then cxl_mbox_cmd_ctor() calls kvzalloc(out.size). A large out.size drives a huge allocation, above INT_MAX it WARNs and taints, and with panic_on_warn=1 it panics. The transport __cxl_pci_mbox_send_cmd() already clamps the response copy to min(out.size, payload_size, device len), so the output buffer is never written beyond payload_size. Clamp the allocation to payload_size too, matching the RAW path. | ||||
| CVE-2026-93148 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Reject MEM_ALLOC BTF accesses past object bounds BTF struct walks relax the struct-size check for accesses through a trailing flexible array. That is valid for ordinary BTF type walking, but PTR_TO_BTF_ID | MEM_ALLOC values point to objects allocated with the static BTF type size. When walking a MEM_ALLOC object, reject the access before applying the flexible-array relaxation if the access range extends past the struct size. Apply the same policy to struct ID matching so kfunc and kptr type checks do not walk past the allocated object bounds either. | ||||
| CVE-2026-93129 | 1 Linux | 1 Linux Kernel | 2026-10-21 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: platform/x86: dell-wmi-base: Fix handling of ultra performance key The commit message of commit 5fbd827eb9c2 ("platform/x86: dell-wmi: Recognise or support new switches") states that the ultra performance key contains additional data after the type and code fields. The event data passed to dell_wmi_process_key() is already parsed, so "buffer" already starts after those two fields. Use the correct index for accessing the first data field to avoid a potential buffer overread. | ||||
| CVE-2026-93125 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Reject rdonly/rdwr_buf_size kfunc arguments that exceed u32 max check_kfunc_args() detects a kfunc argument named rdonly_buf_size or rdwr_buf_size and stores reg->var_off.value into meta->r0_size, a u64, and does not bound it. check_kfunc_call() later copies that value into the returned register's mem_size field: meta->r0_size = reg->var_off.value; ... regs[BPF_REG_0].mem_size = meta.r0_size; regs[BPF_REG_0].mem_size is u32. A constant whose upper 32 bits are set gets truncated instead of causing a load-time rejection, so the verifier records a PTR_TO_MEM register with an approximately 4 GiB mem_size for whatever allocation the kfunc returned. A later access check against that register uses the truncated, wrong bound. Reject rdonly_buf_size/rdwr_buf_size values that exceed U32_MAX at the point meta->r0_size is set. | ||||
| CVE-2026-93122 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: usb: gadget: uac: validate rate list length before storing UAC1 and UAC2 configfs rate-list attributes parse a comma-separated list of sampling rates and store each parsed value in fixed-size arrays. The arrays have UAC_MAX_RATES entries, but the store paths do not check that the input contains at most that many tokens before writing through opts->name##s[i++]. Writing more than ten rates therefore writes past the end of the p_srates[] or c_srates[] array in struct f_uac1_opts or struct f_uac2_opts. With CONFIG_UBSAN_BOUNDS enabled, writing an 11-entry rate list to the UAC1 p_srate attribute reports: UBSAN: array-index-out-of-bounds drivers/usb/gadget/function/f_uac1.c:1669:1 index 10 is out of range for type 'int [10]' __ubsan_handle_out_of_bounds.cold f_uac1_opts_p_srate_store configfs_write_iter vfs_write ksys_write do_syscall_64 The same reproducer against the UAC2 p_srate attribute reports: UBSAN: array-index-out-of-bounds drivers/usb/gadget/function/f_uac2.c:2087:1 index 10 is out of range for type 'int [10]' __ubsan_handle_out_of_bounds.cold f_uac2_opts_p_srate_store configfs_write_iter vfs_write ksys_write do_syscall_64 Reject additional tokens once UAC_MAX_RATES entries have been parsed. Also keep the original kstrdup() pointer for kfree(), because strsep() advances the parsing cursor. Freeing the advanced cursor leaks the original buffer on successful parses and can free an interior pointer on some error paths. | ||||

| In the Linux kernel, the following vulnerability has been resolved: bpf: Fix WARNING in bpf_tracing_link_release The trampoline could be corrupted by the blindly 'tr->flags = BPF_TRAMP_F_TAIL_CALL_CTX' in verifier. 1. A fexit attached to a tail_call_reachable prog. 'tr->flags' became 'BPF_TRAMP_F_CALL_ORIG | BPF_TRAMP_F_TAIL_CALL_CTX'. And, the trampoline would poke the target prog's nop insn using jmp insn instead of call insn. 2. Another fexit loaded with the same tail_call_reachable prog target. 'tr->flags' became 'BPF_TRAMP_F_TAIL_CALL_CTX'. 3. Close the first fexit link. Due to no BPF_TRAMP_F_CALL_ORIG in 'tr->flags', the trampoline will fail to restore the prog's nop insn using call insn.

| CVE-2026-92480 | 1 Linux | 1 Linux Kernel | 2026-10-21 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Validate string descriptors The string descriptor length includes a two-byte header while the UTF-16 payload starts after it. utf16s_to_utf8s() expects a count of UTF-16 code units, not bytes. Passing the payload byte count can make it read beyond the descriptor buffer. Validate that the payload has an even byte count, pass a code-unit count to the converter, and allocate sufficient UTF-8 output space. The raw string buffer starts after the descriptor header but its size is bLength. Copying bLength bytes from that pointer can read beyond the response buffer. Allocate a zeroed bLength-sized buffer and copy only the UTF-16 payload. This preserves the raw buffer size consumed by the RPMB device-ID ABI while avoiding the overread. | ||||
| CVE-2026-90409 | 1 Linux | 1 Linux Kernel | 2026-10-21 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Add vm_bind region with kbo range overlap check When a VM is created, caller has to specify the range of the address space carve-out set aside for mapping kernel BO's. That means vm_bind mappings of UM-exposed BO's should not intersect with that region, but at the moment we're not checking this. At first, I thought of giving these values to drm_gpuvm_init() through its reserve_{offset, range} arguments, but it turns out that is meant for VM address spans that are not managed through the usual drm_gpuvm split/merge circuit, so storing the end of the user VA range at VM creation time and doing a quick check in the vm_bind ioctl path was the simplest workaround. The new check also makes sure vm_bind range doesn't overflow the size of a 64-bit unsigned integer. That was already being done further down the call stack inside drm_gpuvm_sm_map -> drm_gpuvm_range_valid, but it's best to fail early in the driver before GPUVM functions are invoked so that we won't waste time allocating vm_bind context resources. | ||||
| CVE-2026-90399 | 1 Linux | 1 Linux Kernel | 2026-10-21 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix stride mismatch in mac_phy_caps_parse() Currently, in ath12k_wmi_mac_phy_caps_parse(), kzalloc() sizes the mac_phy_caps buffer as tot_phy_id * len, where len is clamped to min(firmware_len, sizeof(struct ath12k_wmi_mac_phy_caps_params)). 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 ath12k_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.
