| CVE-2026-89933 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: iio: pressure: dps310: fix NULL pointer dereference on ACPI probe When the device is enumerated through its ACPI HID (IFX3100), i2c_client_get_device_id() returns NULL: the ACPI-derived client name does not match the driver's i2c_device_id table. dps310_probe() then dereferences that NULL pointer in "iio->name = id->name" and crashes the kernel during probe. The IIO device name is always "dps310", so set it directly and drop the now-unused device-id lookup. | ||||
| CVE-2026-89930 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 9.3 Critical |
| In the Linux kernel, the following vulnerability has been resolved: KVM: nVMX: Service local TLB flushes on failed nested VM-Enter KVM services local TLB flushes on "full" nested VM-Exits (through __nested_vmx_vmexit()), but not if a nested VM-Enter fails (e.g. due to failed VMCS checks in nested_vmx_enter_non_root_mode()). However, it is possible that KVM had queued TLB flushes that need to be performed, even if the nested VM-Enter was not successful. For example, if VPID is disabled for L2 (via nested_vmx_transition_tlb_flush(), or if via the MSR load lists, as the SDM says: If any MSR is being loaded in such a way that would architecturally require a TLB flush, the TLBs are updated so that, after VM entry, the logical processor will not use any translations that were cached before the transition. The SDM is unclear about when the TLB flush should occur, and whether or not a failed VM entry would flush the TLB, so it is safer to always do the TLB flush in this case. More concretely, KVM also updates the last VPID L1 used for L2 in nested_vmx_transition_tlb_flush() (i.e. last_vpid), even if the VM entry ultimately fails. With the current code, KVM could miss a TLB flush if L1 changes L2's VPID, then does a failed VM entry followed by a successful one, as the failed VM entry would update last_vpid but not actually flush the TLB. Servicing local TLB flushes on failed VM entries makes sure that the TLB is always flushed when last_vpid is updated. | ||||
| CVE-2026-89926 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Fix length check __import_wp_info() struct kvm_hw_breakpoint::len is a __u64 that is fully controlled by user space. This is then assigned to wp_info->len, which is an int. The bounds check is done on the truncated value while the allocation uses the untruncated one: wp_info->len = bp_data->len; [...] if (wp_info->len < 0 || wp_info->len > MAX_WP_SIZE) return -EINVAL; wp_info->old_data = kmalloc(bp_data->len, GFP_KERNEL_ACCOUNT); Use the validated value for the allocation as intended. Without this fix userspace can trigger >4GB allocations which will fail and result in a WARN due to MAX_PAGE_ORDER. | ||||
| CVE-2026-89921 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Zero initialize data structures for inject_pfault_token __kvm_inject_pfault_token() only sets .type and .u.ext.ext_params2 of the on-stack struct kvm_s390_irq but the full ext substructure is copied into the cpu local variable on inject. ext_params and pad contain stale stack values. Interrupt delivery only uses ext_params2, so nothing leaks to the guest, but a host user can use the migration ioctls to get to the data. Fix by zero-initializing the irq struct. Do the same for the inti data structure. | ||||
| CVE-2026-89920 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Fix memory corruption by not reinjecting CK machine checks Channel-subsystem damage machine checks are for the host channel subsystem. The guest channel subsystem is emulated in the userspace VMM. There is no point in forwarding such machine checks into the guest. This also simplifies the machine check reinjection and avoids kfree of a stack variable as reported by sashiko. There might be still machine checks that have the ck bit set with another bit (like instruction damage), mask out the CK bit in s390_backup_mcck_info(), like the CP and ED bits already are. | ||||
| CVE-2026-89912 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-its: Don't dereference a NULL collection on ITT save MAPC with V=0 drops ite->collection but leaves the ITE on the device's ITT list, and vgic_its_save_ite() dereferences it unconditionally. A guest that issues MAPD, MAPTI and then MAPC(V=0) therefore oopses the host when the VMM issues KVM_DEV_ARM_ITS_SAVE_TABLES to migrate it. That sequence is UNPREDICTABLE per the architecture, but KVM already handles the resulting state in the translate, MOVI and DISCARD paths. Save a zeroed entry, which vgic_its_restore_ite() reads back as invalid. Skipping the ITE instead would leave the ITT slot holding whatever is in guest memory, and restore rejects an entry naming a collection the restored collection table does not have. | ||||
| CVE-2026-89884 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: media: platform: mtk-mdp3: fix NULL deref on failed SCP lookup Add the missing sanity check after looking up the SCP to avoid dereferencing a NULL-pointer in case its driver has not yet been bound. | ||||
| CVE-2026-89877 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: media: saa7164: fix cleanup on resource allocation failure saa7164_dev_setup() adds the device to the global saa7164_devlist before requesting the PCI BAR memory regions. If get_resources() fails, saa7164_dev_setup() decrements the device count and returns an error, but leaves the device on saa7164_devlist. The probe error path then frees the device, leaving a dangling entry on the global list. Reuse the existing MMIO mapping error path to remove the device from saa7164_devlist and decrement the device count before returning. Also release BAR0 if it was successfully requested but the BAR2 request fails. | ||||
| CVE-2026-89870 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: media: zoran: Avoid freeing a registered video_device twice zoran_init_video_device() installs zoran_vdev_release() as the video_device release callback through zoran_template. After video_register_device() succeeds, video_unregister_device() drops the registered video_device reference and the V4L2 core eventually invokes that release callback, which kfree()s the video_device. zoran_exit_video_devices() called video_unregister_device() and then kfree(zr->video_dev), so device teardown could free the same video_device twice. Remove the direct kfree() and clear the cached pointer after unregistering. The pre-registration failure path keeps its manual free because the video_device was not registered there. This issue was found by a static analysis checker and confirmed by manual source review. | ||||
| CVE-2026-89860 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Initialize NVMe abort_work once at submission qla_nvme_fcp_abort() and qla_nvme_ls_abort() ran INIT_WORK() on priv->abort_work immediately before schedule_work(). INIT_WORK() reinitializes the work_struct, resetting its list head and clearing the pending bit. If an abort is issued more than once for the same command (for example, concurrent transport teardown and a timeout-driven abort), the second INIT_WORK() reinitializes a work item that is already queued, which can corrupt the workqueue list and lead to crashes or a looping worker. Initialize priv->abort_work once at command submission, next to the existing per-command spin_lock_init(&priv->cmd_lock), and leave only schedule_work() in the abort paths. schedule_work() already does nothing when the work item is still pending, so a repeated abort no longer disturbs an in-flight work item. The command is not returned to the transport until the final kref_put()/release callback runs after abort_work has completed, so the work item is idle before priv is reused and the single submission-time INIT_WORK() is safe. | ||||
| CVE-2026-89859 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Zero dport diagnostics buffer to avoid info leak qla2x00_do_dport_diagnostics() allocates the qla_dport_diag response buffer with kmalloc_obj() (non-zeroing) and, on success, copies the full sizeof(*dd) back to user space via sg_copy_from_buffer(). The inbound sg_copy_to_buffer() only fills as many bytes as the user request payload provides, and qla26xx_dport_diagnostics() zeroes only dd->buf. The options and unused[] fields are therefore copied out uninitialized, leaking kernel heap contents to user space. Allocate with kzalloc_obj(), matching qla2x00_do_dport_diagnostics_v2(). | ||||
| CVE-2026-89848 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 8.1 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Quiesce response IRQ before freeing request queue qla2xxx_delete_qpair() deletes the request queue before the response queue. qla25xx_delete_req_que() frees the request queue memory (kfree(req) in qla25xx_free_req_que()), but the response-queue MSI-X is only released later, in qla25xx_free_rsp_que(). In that window the response interrupt can still fire, qla2xxx_msix_rsp_q() queues qpair->q_work, and qla_do_work() -> qla24xx_process_response_queue() dereferences the now-freed rsp->req (LOGINOUT/CT/ELS entries and the status path), a use-after-free. The cancel_work_sync() added for the qpair teardown lives in the response free path, which runs after the request queue is already freed, so it does not protect rsp->req. Release the response-queue interrupt and flush qpair->q_work before deleting the request queue, so no late completion can reach the freed request queue. Clearing have_irq makes the subsequent qla25xx_free_rsp_que() skip its free_irq(), and the firmware queue-delete order (request then response) is preserved; the request-delete mailbox completes on the default vector and is unaffected by dropping the qpair response interrupt early. | ||||
| CVE-2026-89840 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: f2fs: validate MOVE_RANGE destination size F2FS_IOC_MOVE_RANGE checks the source range, but not the destination end before updating i_size. A source hole can expose this: __clone_blkaddrs() skips NULL_ADDR entries and returns success, so the caller can still extend the destination inode with unchecked pos_out + len. Reject destination overflow and use inode_newsize_ok() before extending the destination inode. | ||||
| CVE-2026-89838 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: f2fs: limit recovery filename logging to stored length F2FS stores recovery filenames as a length plus a fixed-size i_name buffer. The buffer is not NUL-terminated, but recover_inode() and recover_dentry() print it with %s. For a 255-byte filename, recovery logging can read past i_name into the following raw inode fields. Print the name with a precision bounded by i_namelen and F2FS_NAME_LEN. | ||||
| CVE-2026-89837 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: f2fs: fix dentry folio leak in find_in_level find_in_level() gets a dentry folio with f2fs_find_data_folio() before calling find_in_block(). If find_in_block() returns an error, the function stores the error in res_folio and breaks out of the loop without dropping the dentry folio. This leaks the folio reference on the find_in_block() error path. Drop the dentry folio before returning the error to the caller. | ||||
| CVE-2026-89835 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: f2fs: avoid NULL checkpoint thread access in sysfs checkpoint_merge can be enabled even when no checkpoint merge thread is running. A read-only mount is one case: f2fs does not start f2fs_issue_ckpt there, but ckpt_thread_ioprio is still writable through sysfs. The ckpt_thread_ioprio store path updates the saved ioprio value and, when checkpoint_merge is enabled, calls set_task_ioprio() for the checkpoint thread. If cprc->f2fs_issue_ckpt is NULL, that dereferences a NULL task pointer. Protect ckpt_thread_ioprio sysfs writes with s_umount as well, so the checkpoint thread cannot disappear under the store path while updating its ioprio. | ||||
| CVE-2026-89834 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to migrate all curseg types during free_segment_range In free_segment_range(), the curseg evacuation loop only iterates up to NR_CURSEG_PERSIST_TYPE (0..5), missing non-persistent in-memory curseg types such as CURSEG_COLD_DATA_PINNED and CURSEG_ALL_DATA_ATGC. Even though these in-memory curseg types are not saved in the on-disk checkpoint header, they still occupy active physical segments at runtime. If an active in-memory curseg happens to be allocated within the segment range being truncated during filesystem shrink, failing to evacuate it will cause subsequent writes to the curseg attempting out-of-bounds I/O on the truncated storage range. Fix this by expanding the curseg evacuation loop upper bound to NR_CURSEG_TYPE to ensure all active curseg types are safely migrated out of the target range. | ||||
| CVE-2026-89833 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to avoid potential deadloop in f2fs_fsync_node_pages() There is potential deadloop in race condition: Thread A Thread B - fsync - f2fs_do_sync_file - f2fs_fsync_node_pages - last_fsync_dnode - folio_get(last_folio) - f2fs_setattr - f2fs_truncate - f2fs_truncate_blocks - f2fs_do_truncate_blocks - f2fs_truncate_inode_blocks - truncate_dnode - truncate_node - invalidate_mapping_pages - folio->mapping = NULL - is_node_folio alwasy return false - atomic && !marked is always true, then goto retry | ||||
| CVE-2026-89832 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to clear dirty flag on folio in error path If node block is corrupted due to chksum mismatch or inconsistent footer info, it needs to drop clear flag of node folio, in order to persist inconsistent node data to storage. | ||||
| CVE-2026-89813 | 1 Linux | 1 Linux Kernel | 2026-10-30 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: force complete the KIQ ring fences on reset Like the MES scheduler ring, the KIQ ring sets no_scheduler = true and uses a polling fence, so it is skipped by the force-completion loop in amdgpu_device_pre_asic_reset(). Its hw fence value lives in wb (GTT) memory and survives a MODE1 reset while fence_drv.sync_seq keeps advancing, so after a reset the first KIQ submission can poll forever on a seq that is never written back. Force complete the KIQ ring fences too so their hw fence is realigned to sync_seq. | ||||
