| CVE-2026-97532 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Null out freed pointers in qla2x00_mem_alloc() error path When qla2x00_mem_alloc() fails, qla2x00_probe_one() jumps to probe_hw_failed and calls qla2x00_mem_free(). Several error labels in qla2x00_mem_alloc() freed adapter members (elsrej.c, purex_dma_pool, flt, sfp_data, loop_id_map, async_pd, sf_init_cb, ex_init_cb, npiv_info) but left the pointers dangling. qla2x00_mem_free() then freed them a second time. Worse, for the dma_pool members it issued dma_pool_free(ha->s_dma_pool, ...) after s_dma_pool had already been destroyed and set to NULL at fail_s_dma_pool, dereferencing a NULL pool. Clear each freed pointer (and its DMA handle) in the error labels so the subsequent qla2x00_mem_free() skips them. | ||||
| CVE-2026-97531 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Skip vport under deletion in report ID acquisition qla24xx_report_id_acquisition() format-1 handling walks ha->vp_list under vport_slock, takes a vref_count on the matching vport and calls qla_update_host_map() to register its port id. A vport teardown via qla24xx_vport_delete() sets VPORT_DELETE, then qla24xx_disable_vp() removes the vport from the host_map btree and zeroes vha->d_id (RESET_AL_PA). The vport is only unlinked from vp_list later, in qla24xx_deallocate_vp_id(), which clears vp_map[idx] (RESET_VP_IDX) but does not touch host_map. In the window in between, report ID acquisition can still find the vport on vp_list and call qla_update_host_map(); with d_id already zeroed it takes the btree_insert32() path and re-inserts the dying vport into host_map. Nothing cleans that entry afterwards, so once scsi_host_put() frees the vha a later host_map lookup dereferences freed memory. Skip a vport that has VPORT_DELETE set before taking the reference, so it is neither re-registered nor scheduled for DPC re-registration. This mirrors the existing guard in qla2x00_alert_all_vps(). | ||||
| CVE-2026-97505 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 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 | 2026-10-30 | 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-2026-97493 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Bound GPIO I2C table entry count from VBIOS Reject undersized tables and cap the derived entry count to AMDGPU_MAX_I2C_BUS so we do not overrun adev->i2c_bus[] or walk an absurd number of entries on corrupt size fields. | ||||
| CVE-2026-97478 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: virt: acrn: Fix irqfd use-after-free during eventfd shutdown acrn_irqfd_deassign() and the eventfd EPOLLHUP wakeup can race and free the same struct hsm_irqfd: CPU0 CPU1 ---- ---- eventfd_release() wake_up_poll(EPOLLHUP) hsm_irqfd_wakeup() queue_work(&irqfd->shutdown) acrn_irqfd_deassign() hsm_irqfd_shutdown() list_del_init() eventfd_ctx_remove_wait_queue() eventfd_ctx_put() kfree(irqfd) hsm_irqfd_shutdown_work() container_of(work, ..., shutdown) irqfd->vm <-- use-after-free The deassign path freed the irqfd while a shutdown work item was already queued by EPOLLHUP (or vice versa), so the work item could resurrect a dangling pointer through container_of(). Switch to the lifetime model used by KVM irqfds: - Deassign/deinit only deactivate the irqfd: remove it from vm->irqfds under irqfds_lock and queue the cleanup work. - hsm_irqfd_shutdown_work() becomes the sole owner that unhooks the eventfd waitqueue entry, drops the eventfd reference and frees the irqfd. - A new HSM_IRQFD_FLAG_SHUTDOWN bit guarded by test_and_set_bit() ensures the cleanup work is queued at most once, no matter how many of {EPOLLHUP, deassign, deinit} fire concurrently. This is safe to call from the waitqueue callback, which runs with wqh->lock held and IRQs disabled and therefore cannot take irqfds_lock. - acrn_irqfd_deassign() flushes vm->irqfd_wq before returning so the eventfd is fully detached on return. acrn_irqfd_deinit() deactivates every irqfd, flushes the workqueue and only then destroys it, so no path can queue_work() onto a torn-down workqueue. - acrn_irqfd_assign() now installs the eventfd waitqueue entry and publishes the irqfd to vm->irqfds under irqfds_lock, so the irqfd is never visible to deassign/deinit before its waitqueue entry is in place, and any EPOLLHUP that fires in the assign window queues cleanup work that blocks on irqfds_lock until publication is done. | ||||
| CVE-2026-97425 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix buffer overflow during vBIOS update Clamp the buffer postion to write by setting the bin attribute to the maximum buffer size so that VFS layer will block the out-of-bounds accessing. | ||||
| CVE-2026-97422 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix SMI event cross-process information leak kfd_smi_ev_enabled() skips the suser privilege check when pid=0. PROCESS_START, PROCESS_END, and VMFAULT events are emitted with pid=0 while carrying another process's PID and command name, so any /dev/kfd user in the render group can monitor all GPU workloads. Pass the target process PID into kfd_smi_event_add() for these events so the existing per-client filter restricts delivery to the owning process or CAP_SYS_ADMIN subscribers. | ||||
| CVE-2026-97409 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: nvme-fc: Do not cancel requests in io target before it is initialized A new nvme-fc controller in CONNECTING state sees admin request timeout schedules ctrl->ioerr_work to abort inflight requests. This ends up calling __nvme_fc_abort_outstanding_ios() which aborts requests in both admin and io tagsets. In case fc_ctrl->tag_set was not initialized we see the warning below. This is because ctrl.queue_count is initialized early in nvme_fc_alloc_ctrl(). nvme nvme0: NVME-FC{0}: starting error recovery Connectivity Loss INFO: trying to register non-static key. The code is fine but needs lockdep annotation, or maybe lpfc 0000:ab:00.0: queue 0 connect admin queue failed (-6). you didn't initialize this object before use? turning off the locking correctness validator.

| CVE-2026-93817 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: perf: Fix addr_filter_ranges lifetime Lee Jia Jie reported that since event::addr_filter_ranges is used under RCU, it should be RCU freed. | ||||
| CVE-2026-93796 | 1 Linux | 2 Kernel, Linux Kernel | 2026-10-30 | 7 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: pcie: null RX pointers after free When iwl_pcie_tx_init() fails after RX init, nic init unwinds via iwl_pcie_rx_free(). The freed RX members stayed non-NULL on the live transport object, so later teardown or retry could touch stale RX state. Set rx_pool, global_table, rxq, and alloc_page to NULL after free to make repeated cleanup and retry paths safe. | ||||
| CVE-2026-93793 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 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-2026-93790 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix out-of-bounds tid_data access in BA notif mvmsta->tid_data was indexed by the TFD loop counter 'i' instead of the actual TID value 'tid'. This writes lq_color into a random tid_data slot unrelated to the BA entry. Since multi-TID blockack is not really in use, 'i' was always 0 and no harm was done. Add a out-of-bound check before accessing the array. | ||||
| CVE-2026-93786 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 8.1 High |
| In the Linux kernel, the following vulnerability has been resolved: ksmbd: preserve VFS inherited POSIX ACL mask The VFS initializes a child's POSIX ACL from the parent's default ACL and the requested creation mode. Do not mutate the parent ACL or overwrite the child's VFS-computed access and default ACLs afterwards. This preserves restrictive ACL_MASK entries and prevents SMB object creation from widening effective permissions. | ||||
| CVE-2026-93282 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 8.1 High |
| In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix maximum allowed access checks The DACL permission check looks for an ACE matching the current user and falls back to the Everyone ACE. It does not consider an Authenticated Users ACE, even though an authenticated session is a member of that well-known group. As a result, opening a file whose access is granted through S-1-5-11 can incorrectly fail with STATUS_ACCESS_DENIED. Treat an Authenticated Users ACE as a fallback entry alongside Everyone. The maximal access calculation also combines access masks from every ACE, regardless of whether its SID applies to the current user. This can grant rights belonging to an unrelated principal. Process only ACEs applying to the user, Everyone, or Authenticated Users, and accumulate allowed and denied masks in ACL order. Preserve explicitly requested access bits so they are validated against the resulting maximal mask. When ACCESS_SYSTEM_SECURITY is denied, report STATUS_PRIVILEGE_NOT_HELD instead of the generic STATUS_ACCESS_DENIED. Access to the system ACL requires a security privilege that ksmbd does not grant. For regular files, include FILE_EXECUTE in maximal access when the client requested GENERIC_EXECUTE and the DACL grants the complete file-read set. Keep a direct FILE_EXECUTE request subject to the explicit DACL bit. This matches the POSIX file ACL mapping without broadening specific execute requests. Do not replace rights from an applicable NT ACE with a POSIX ACL entry. The POSIX ACL is only a fallback when no user, Everyone, or Authenticated Users ACE applies; otherwise it can incorrectly broaden the stored DACL. This fixes smb2.maximum_allowed.maximum_allowed. | ||||
| CVE-2026-93260 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.4 High |
| In the Linux kernel, the following vulnerability has been resolved: powerpc/xive: propagate IPI init errors to prevent use-after-free When xive_init_ipis() fails (e.g. irq_domain_alloc_irqs() fails), the error path frees the global xive_ipis array. However, xive_smp_probe() previously ignored this failure and proceeded to call xive_setup_cpu_ipi(), which dereferences the already-freed xive_ipis pointer -- a use-after-free. Now that xive_smp_probe() returns int (previous patch), propagate the error from xive_init_ipis() and xive_setup_cpu_ipi() through xive_smp_probe(). Check the return value in both pnv_smp_probe() and pSeries_smp_probe() so that IPI setup is aborted cleanly on failure, avoiding the use-after-free. | ||||
| CVE-2026-93196 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: nvdimm: virtio_pmem: refcount requests for token lifetime KASAN reports slab-use-after-free in __wake_up_common(): BUG: KASAN: slab-use-after-free in __wake_up_common+0x114/0x160 Read of size 8 at addr ffff88810fdcb710 by task swapper/0/0 CPU: 0 UID: 0 PID: 0 Comm: swapper/0 Not tainted 6.19.0-next-20260220-00006-g1eae5f204ec3 #4 PREEMPT(full) Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Arch Linux 1.17.0-2-2 04/01/2014 Call Trace: <IRQ> dump_stack_lvl+0x6d/0xb0 print_report+0x170/0x4e2 ? __pfx__raw_spin_lock_irqsave+0x10/0x10 ? __virt_addr_valid+0x1dc/0x380 kasan_report+0xbc/0xf0 ? __wake_up_common+0x114/0x160 ? __wake_up_common+0x114/0x160 __wake_up_common+0x114/0x160 ? __pfx__raw_spin_lock_irqsave+0x10/0x10 __wake_up+0x36/0x60 virtio_pmem_host_ack+0x11d/0x3b0 ? sched_balance_domains+0x29f/0xb00 ? __pfx_virtio_pmem_host_ack+0x10/0x10 ? _raw_spin_lock_irqsave+0x98/0x100 ? __pfx__raw_spin_lock_irqsave+0x10/0x10 vring_interrupt+0x1c9/0x5e0 ? __pfx_vp_interrupt+0x10/0x10 vp_vring_interrupt+0x87/0x100 ? __pfx_vp_interrupt+0x10/0x10 __handle_irq_event_percpu+0x17f/0x550 ? __pfx__raw_spin_lock+0x10/0x10 handle_irq_event+0xab/0x1c0 handle_fasteoi_irq+0x276/0xae0 __common_interrupt+0x65/0x130 common_interrupt+0x78/0xa0 </IRQ> virtio_pmem_host_ack() wakes a request that has already been freed by the submitter. This happens when the request token is still reachable via the virtqueue, but virtio_pmem_flush() returns and frees it. Fix the token lifetime by refcounting struct virtio_pmem_request. virtio_pmem_flush() holds a submitter reference, and the virtqueue holds an extra reference once the request is queued. The completion path drops the virtqueue reference, and the submitter drops its reference before returning. | ||||
| CVE-2026-93192 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Clear queue->active_job when v3d_fence_create() fails The run_job() callbacks for BIN, RENDER, TFU and CSD assign the incoming job to queue->active_job before calling v3d_fence_create(). If v3d_fence_create() fails, the callback returns NULL without clearing active_job, leaving a dangling pointer. Create a failure path in all run_job() callbacks that clears the active job before returning NULL. The BIN path takes queue->queue_lock around the clear as it races against v3d_overflow_mem_work(); RENDER, TFU and CSD paths have no concurrent reader, so the clear is lock-free. | ||||

| In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix dangling pointer in plane reset function amdgpu_dm_plane_drm_plane_reset() frees the old state before allocating a new one. If kzalloc() fails, the function returns without updating the state pointer, leaving a dangling pointer to already freed memory. Fix this by allocating the new state first. On allocation failure, the old state remains untouched and the function safely returns. Found by Linux Verification Center (linuxtesting.org) with SVACE.
