Meanwhile the memory of the @name is only 255 byte sized, this will cause out-of-boundary access, and cause the above crash. [FIX] Add extra namelen verification for INODE_REF, just like what we have done in ROOT_REF checks.

| CVE-2026-93816 | 1 Linux | 1 Linux Kernel | 2026-09-26 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: f2fs: validate inline dentry name lengths before conversion Inline dentry conversion copies names out of the inline dentry area before checking that each recorded name length fits in the available filename slots. A corrupted image can therefore make the conversion path read past the inline filename storage while building the regular dentry block. Validate each inline dentry name length against the inline filename area before copying it. | ||||

| CVE-2026-93827 | 1 Linux | 1 Linux Kernel | 2026-09-26 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: virtio-fs: avoid double-free on failed queue setup virtio_fs_setup_vqs() allocates fs->vqs and fs->mq_map before calling virtio_find_vqs(). If virtio_find_vqs() fails, the error path frees both pointers and returns an error to virtio_fs_probe(). virtio_fs_probe() then drops the last kobject reference, and virtio_fs_ktype_release() frees fs->vqs and fs->mq_map again. This leaves dangling pointers in struct virtio_fs and can trigger a double-free during probe failure cleanup. Set fs->vqs and fs->mq_map to NULL immediately after kfree() in the virtio_fs_setup_vqs() error path so that the later kobject release sees an uninitialized state and kfree(NULL) becomes harmless. This can be reproduced when a broken virtio-fs device advertises more request queues than the transport actually provides. In that case virtio_find_vqs() fails while setting up the extra queue, and the probe path reaches the double-free cleanup sequence. | ||||
| CVE-2026-97409 | 1 Linux | 1 Linux Kernel | 2026-09-26 | 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.

| CVE-2026-97413 | 1 Linux | 1 Linux Kernel | 2026-09-26 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs-srv: Fix integer underflow in process_read and process_write usr_len is read from a network-supplied message field (le16_to_cpu) and used to compute data_len = off - usr_len without validating that usr_len <= off. A malicious RDMA client can send usr_len > off causing an integer underflow, resulting in data_len wrapping to a huge size_t value which is then passed to the rdma_ev callback as a memory length, leading to out-of-bounds memory access. Fix by reading and validating usr_len <= off before rtrs_srv_get_ops_ids() in both process_read() and process_write(), ensuring the early return path acquires no reference and has no resource leak. | ||||

| In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: validate index entry key bounds [BUG] A malformed NTFS directory index entry can advertise a key_size larger than the bytes actually present in its NTFS_DE payload.

[CAUSE] The index-header validators only validated INDEX_HDR-level geometry. They did not walk each NTFS_DE to verify entry alignment, subnode layout, or that key_size fit inside the entry payload.

[FIX] Walk every NTFS_DE in ntfs3's index-header validators and reject entries with invalid layout, mismatched subnode state, oversized key_size, or non-zero sentinel keys before lookup or log replay can consume them. | ||||

| CVE-2026-97991 | 1 Linux | 1 Linux Kernel | 2026-09-26 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: vdpa_sim_blk: reject out-of-range sector starts vdpasim_blk_check_range() logs an invalid start sector but continues validating the request. The subsequent unsigned capacity subtraction can underflow and let an out-of-range buffer offset reach the data path. The invalid offset is used by three request paths. VIRTIO_BLK_T_OUT copies guest data to blk->buffer + offset through vringh_iov_pull_iotlb(), causing an out-of-bounds write in _copy_from_iter() or memcpy(). VIRTIO_BLK_T_IN copies from blk->buffer + offset to the guest through vringh_iov_push_iotlb(), causing an out-of-bounds read in _copy_to_iter(). VIRTIO_BLK_T_WRITE_ZEROES passes blk->buffer + offset to memset(), causing an out-of-bounds write. Reject starts at or beyond the capacity before the subtraction. Treat the capacity boundary as invalid because the IN and OUT paths round byte counts down to sectors for validation but later copy the original byte counts. A sub-sector request at the capacity boundary would otherwise still access past the end of the buffer. I found this bug myself, though the patch was written with AI assistance. | ||||
| CVE-2026-97992 | 1 Linux | 1 Linux Kernel | 2026-09-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: vhost-vdpa: protect config_ctx from being freed under the config callback vhost_vdpa_config_cb() loads v->config_ctx and signals it without taking a reference and without holding any lock: struct eventfd_ctx *config_ctx = v->config_ctx; if (config_ctx) eventfd_signal(config_ctx); VHOST_VDPA_SET_CONFIG_CALL replaces that field and drops what is normally the last reference to the old context: swap(ctx, v->config_ctx); if (ctx) eventfd_ctx_put(ctx); eventfd_ctx_put() drops the last kref and frees the context immediately, with no RCU grace period, so a callback that has already loaded the pointer goes on to dereference freed memory. The two sides share no lock: the ioctl runs under vhost_dev.mutex, while the parent invokes the callback from its own interrupt or workqueue context. This is not the reopen refcount underflow fixed by commit f6bbf0010ba0 ("vhost-vdpa: fix use-after-free of v->config_ctx"), which was about vhost_vdpa_config_put() leaving a stale pointer behind. Here the pointer is maintained correctly and it is the read side that is unprotected. With VDUSE as the parent this is reachable from userspace with access to /dev/vduse (root by default). VDUSE_DEV_INJECT_CONFIG_IRQ queues dev->inject, and vduse_dev_irq_inject() runs the callback under VDUSE's own dev->irq_lock, which vhost does not hold. vduse_dev_reset() does flush_work(&dev->inject), but VHOST_VDPA_SET_CONFIG_CALL never goes through reset, so an inject already in flight is not waited for. A process that injects config interrupts on the VDUSE fd while another thread swaps the call fd on the vhost-vdpa fd hits it in seconds: BUG: KASAN: slab-use-after-free in native_queued_spin_lock_slowpath Read of size 4 at addr ffff888107d21808 by task kworker/u17:1/2993 Workqueue: vduse-irq vduse_dev_irq_inject Call Trace: native_queued_spin_lock_slowpath+0x97/0x5b0 _raw_spin_lock_irqsave+0xd4/0xe0 eventfd_signal_mask+0x69/0x120 vhost_vdpa_config_cb+0x34/0x50 vduse_dev_irq_inject+0x46/0x60 process_one_work+0x468/0x950 Allocated by task 2992: do_eventfd+0x50/0x200 __x64_sys_eventfd2+0x2e/0x40 Freed by task 2992: eventfd_ctx_put+0xb9/0xc0 vhost_vdpa_unlocked_ioctl+0x116c/0x2190 Add a spinlock covering every access to config_ctx, so the callback either signals a context that is still alive or observes NULL, and the put happens only once no callback can reach the old value. Clearing the parent's callback before the put would not be enough: of the in-tree set_config_cb() implementations only VDUSE takes a lock, the rest store the pointer unlocked, so that would not order against an in-flight invocation. | ||||
| CVE-2026-97527 | 1 Linux | 1 Linux Kernel | 2026-09-26 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Serialize NVMe unsol ctx list with a per-fcport lock The fcport->unsol_ctx_head list is modified from several contexts without a common lock. Entries are added in qla2xxx_process_purls_iocb() from the response queue ISR (under the qpair qp_lock), while they are removed from qla2xxx_process_purls_pkt() (DPC/purex worker), qla_nvme_xmt_ls_rsp() (NVMe-FC transport callback) and qla_nvme_release_lsrsp_cmd_kref() (SRB completion). The qpair qp_lock cannot serialize this per-fcport list since multiqueue adapters add entries through different qpairs, so a concurrent add and delete (or two concurrent deletes) can corrupt the list pointers. Introduce a dedicated per-fcport spinlock, unsol_ctx_lock, initialized in qla2x00_alloc_fcport(), and take it around every list_add_tail()/list_del() on unsol_ctx_head. The add nests under the existing qp_lock; no delete path takes qp_lock, so the lock order is consistent and deadlock free. | ||||
| CVE-2026-97575 | 1 Linux | 1 Linux Kernel | 2026-09-26 | 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. | ||||
