| CVE-2026-93078 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: cxl/features: Reject Set Features output buffer smaller than the header cxlctl_set_feature() sizes its output buffer from the user's fwctl_rpc.out_len but never checks it is large enough to hold even the fwctl_rpc_cxl_out header. With out_len == 0 , kvzalloc() returns ZERO_SIZE_PTR, which passes the !rpc_out check, the subsequent rpc_out->size = 0 then writes through the poison pointer. Reject requests whose output buffer can't hold the response header, before allocating. The Set Feature reply carries no payload, so the header is all that is required. | ||||
| CVE-2026-93138 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Fix vmlinux BTF prep race in bpf_get_btf_vmlinux bpf_get_btf_vmlinux() lazily parses the vmlinux BTF under the bpf_verifier_lock, but publishes the result through a plain store and re-checks it through a plain lockless load. Nothing orders the stores initializing the struct btf inside btf_parse_vmlinux() against the store publishing the pointer: On a weakly ordered arch, a concurrent first-time caller taking the lockless fast path could in principle observe the pointer before the parsed contents are visible. The mutex_unlock() does not help such a reader given it only synchronizes with a later acquisition of the same lock. Thus, publish the pointer with smp_store_release() and read it on the fast path with smp_load_acquire(). Acquire semantics are needed rather than a dependency-ordered READ_ONCE(): btf_parse_vmlinux() also populates globals outside the returned object (e.g. bpf_ctx_convert.t). An address dependency would only order accesses performed through the pointer and not cover other globals. | ||||

| CVE-2026-89881 | 1 Linux | 2 Kernel, Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: media: rtl2832_sdr: use vb2_video_unregister_device() on remove to fix DMA leak rtl2832_sdr_remove() runs on USB disconnect and clears dev->udev to NULL before any pending streaming teardown has run. When user space later closes its file descriptor, vb2 calls rtl2832_sdr_stop_streaming() which in turn calls rtl2832_sdr_free_stream_bufs(). That helper releases each coherent buffer with: usb_free_coherent(dev->udev, dev->buf_size, dev->buf_list[dev->buf_num], dev->dma_addr[dev->buf_num]); usb_free_coherent() returns immediately when its dev argument is NULL, so every DMA stream buffer that was live at disconnect is silently leaked. The URBs allocated in rtl2832_sdr_alloc_urbs() outlive the device for the same reason. The rtl2832_sdr driver uses vb2_fop_release() in its file_operations, so replace video_unregister_device(&dev->vdev) with vb2_video_unregister_device(&dev->vdev) and move it before clearing dev->udev. vb2_video_unregister_device() releases the vb2 queue, which synchronously runs rtl2832_sdr_stop_streaming() if streaming is active, so URBs and coherent DMA stream buffers are freed while dev->udev is still valid. vb2_video_unregister_device() locks vdev->queue->lock (vb_queue_lock) internally, and stop_streaming() locks v4l2_lock, so the previous outer mutex_lock(&dev->vb_queue_lock) / mutex_lock(&dev->v4l2_lock) pair around the unregister sequence would self-deadlock and has been removed. A short v4l2_lock critical section around dev->udev = NULL remains so any ioctl path that still holds the file descriptor sees coherent state.

| CVE-2026-92484 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fix use-after-free in find_pos_and_ways() error path The error path releases its reference to a switch decoder before logging an error that includes the decoder name. If the released reference is the last one, the decoder can be freed before the error message accesses its name. Drop the reference after the error is reported. | ||||
| CVE-2026-92491 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Roll back partial protocol table registration scmi_protocol_table_register() can leave earlier requests registered when a later entry in the same ID table fails. Each request retains a pointer to the driver's ID table, so a failed module load can leave a dangling pointer after the module storage is released. Unrequest only the successfully registered prefix, in reverse order, before returning the failure. Leave the failed entry and the remaining entries untouched because matching requests can be owned by another driver. | ||||
| CVE-2026-92498 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: ath6kl: avoid buffer overreads in WMI event handlers The following WMI event handlers currently read from the event buffer without first verifying that the message was large enough to hold the expected event: ath6kl_wmi_scan_complete_rx() ath6kl_wmi_addba_req_event_rx() ath6kl_wmi_delba_req_event_rx() Add length checks to prevent overread. | ||||
| CVE-2026-92499 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ext4: validate readdir offset before accessing dirent A corrupted directory can trigger the following KASAN report when ext4_readdir() resumes from an invalid position: BUG: KASAN: use-after-free in __ext4_check_dir_entry+0x5ef/0x820 Read of size 2 at addr ffff88810a646000 by task repro_linear/509 Call Trace: <TASK> dump_stack_lvl+0x53/0x70 print_report+0xd0/0x630 kasan_report+0xce/0x100 __ext4_check_dir_entry+0x5ef/0x820 ext4_readdir+0xcde/0x2b70 iterate_dir+0x1a1/0x520 __x64_sys_getdents64+0x12b/0x220 do_syscall_64+0xf9/0x540 entry_SYSCALL_64_after_hwframe+0x77/0x7f </TASK> KASAN reports use-after-free because the out-of-bounds access lands in an adjacent freed page. The directory buffer itself is still referenced. ext4_dir_llseek() invalidates the directory cookie so that ext4_readdir() rescans directory entries from the start of the block. The rescan checks only the lower bound of rec_len before advancing. A corrupted rec_len can therefore place the offset where the block has insufficient space for a complete directory entry. The rescan itself may dereference that truncated entry, or the main loop may pass it to __ext4_check_dir_entry(). The latter reads de->rec_len before validating the range. For example: block offset 0 4092 4096 |---- de1.rec_len = 4092 -----|----| de2.inode | de2.rec_len ^ OOB, reported as UAF de2 starts at offset 4092 in this 4 KiB block. Its four-byte inode fits in the block, but its rec_len starts at offset 4096 and crosses the boundary. The minimum safe length is inode-dependent. Encrypted and casefolded directory entries need eight additional hash bytes, while a valid metadata checksum tail is only 12 bytes. Cache the metadata checksum feature state and derive the minimum directory entry length from the on-disk format. Use it to bound both the rescan and the offset passed to the main loop. Report an offset in a truncated block tail and skip the remainder of the block, while continuing to accept an offset exactly at the block boundary. | ||||
| CVE-2026-92504 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7 High |
| In the Linux kernel, the following vulnerability has been resolved: thermal: intel: int3400: clean up ODVP on probe failures evaluate_odvp() creates per-ODVP sysfs files before the thermal zone and later probe resources are registered. The current unwind path only calls cleanup_odvp() from the late sysfs failure path, so failures after evaluate_odvp() but before that label, including thermal_tripless_zone_device_register() failures, leave the ODVP files and storage behind. Move the ODVP cleanup to the common ART/TRT unwind path so every failure after evaluate_odvp() releases the ODVP state. Also clear the cached ODVP pointers in cleanup_odvp(), because evaluate_odvp() can already call it for partial setup failures while probe continues. | ||||
| CVE-2026-92505 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Fix undefined behavior in devid_write debugfs function When for_each_pci_segment() loop completes without finding a matching segment, the pci_seg pointer is not NULL but points to an invalid memory location (the list head). Accessing pci_seg->id after the loop causes undefined behavior. Fix this by handling the successful case inside the loop and returning -EINVAL after the loop if no matching segment is found. | ||||
| CVE-2026-92507 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fix potential use after free in ib_dealloc_pd_user() When accessing a PD via the netlink path the only synchronization mechanism for the said PD is rdma_restrack_get(). Currently, rdma_restrack_del() is invoked at the end of ib_dealloc_pd_user(), which is too late, since by that point vendor-specific resources associated with the PD might already be freed. This can leave a short window where the PD remains accessible through restrack, leading to a potential use-after-free. Fix this by moving the rdma_restrack_begin_del() call to the start of ib_dealloc_pd_user(), ensuring that the PD is removed from restrack before its internal resources are released. This guarantees that no new users hold references to a PD that is in the process of destruction. In addition, this change preserves the intended inverted order between create and destroy routines: resources are added to restrack at the end of successful creation, and hence shall be removed from the restrack first thing during the destruction flow, which keeps the lifecycle management consistent and predictable. | ||||
| CVE-2026-92510 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fix potential use after free in ib_destroy_srq_user() When accessing a SRQ via the netlink path the only synchronization mechanism for the said SRQ is rdma_restrack_get().

| CVE-2026-92518 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: riscv, bpf: Fix kernel stack corruption in tailcall with CFI When CONFIG_CFI_CLANG is enabled, prog->bpf_func already skips the kcfi instruction during setup. Including it again in the tailcall jump offset causes it to jump over an extra 4 bytes, skipping the stack pointer adjustment, which will result in kernel stack corruption. | ||||
| CVE-2026-92523 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/nldev: validate dynamic counter attribute length RDMA_NLDEV_ATTR_STAT_HWCOUNTERS is a nested attribute whose children are consumed directly with nla_get_u32(). The top-level policy validates only the container, so it does not establish the fixed shape of each child. Require every child payload to be exactly one u32 before reading it. | ||||
| CVE-2026-93038 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: iio: dac: ad5686: missing NULL check on match data Verify that chip_info pointer is not NULL. If a user binds the driver using driver_override via sysfs with a device name not present in the id_table or of_match_table, match data will be NULL. | ||||
| CVE-2026-93040 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: Serialize channel state checks pause() and resume() read and update channel state without holding vc.lock, while the interrupt handlers update the same state under it. Take the same lock around those state checks so that request, status, and configured stay consistent. For example, pause() can observe EDMA_ST_BUSY right before the interrupt handler completes the final descriptor and moves the channel to EDMA_ST_IDLE, and then record EDMA_REQ_PAUSE on an already idle channel. No further interrupt will acknowledge the request, and since issue_pending() requires EDMA_REQ_NONE, the channel is wedged for good: terminate_all() leaves the stale request behind, so even reconfiguring the channel does not recover it. issue_pending() already runs under vc.lock, but it tests configured before taking it. Move that test under the lock as well, so configured, request, and status are evaluated as one channel-state snapshot. | ||||
| CVE-2026-93092 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Unregister device notifier before IDR teardown The requested-devices notifier looks up protocol fwnodes from the active_protocols IDR. During remove, unregister the notifier before releasing and destroying active_protocols so no notifier callback can race with the IDR teardown. Keep the bus notifier registered until after the protocol state is torn down, matching the existing remove ordering for SCMI bus users. | ||||
| CVE-2026-93115 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: platform/mellanox: mlxbf-pmc: Check ACPI_COMPANION() against NULL Every platform driver can be forced to match a device that doesn't match its list of device IDs because of device_match_driver_override(), so platform drivers that rely on the existence of a device's ACPI companion object need to verify its presence. mlxbf_pmc_probe() passes the result of ACPI_COMPANION() to acpi_device_hid(), which dereferences it, so force-binding the driver to a device without an ACPI companion leads to a NULL pointer dereference. Accordingly, add a requisite ACPI_COMPANION() check against NULL to the mlxbf-pmc driver and return -ENODEV when the companion is missing. | ||||
| CVE-2026-93052 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: misc: bcm-vk: Use acquire/release for msgq_inited bcm_vk_sync_msgq() fills the message queue information and then sets msgq_inited. Readers call bcm_vk_drv_access_ok() before accessing the message queues and their cached queue information. atomic_set()/atomic_read() do not order those accesses. A reader can see msgq_inited set while still seeing stale queue information. Use release when publishing the initialized queues and acquire when checking the gate. Keep the clear in bcm_vk_blk_drv_access() as atomic_set(). It closes the gate and does not publish queue state to readers. | ||||
| CVE-2026-93057 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Avoid possible memory reclaim deadlock in TX EQTR context TX EQTR may run while devfreq gear scaling has quiesced the UFS tagset. In that context, functions ufshcd_tx_eqtr(), __ufshcd_tx_eqtr() and ufs_qcom_get_rx_fom() allocate memory with GFP_KERNEL. If direct reclaim is triggered, reclaim/writeback can depend on I/O to UFS device. Because the queue is quiesced, this can cause deadlock. Use memalloc_noio_save/restore() in ufshcd_tx_eqtr() to cover all allocations in the TX EQTR call tree, including: - params->eqtr_record in ufshcd_tx_eqtr() - eqtr_data in __ufshcd_tx_eqtr() - params in ufs_qcom_get_rx_fom() This is preferred over tagging individual call sites with GFP_NOIO, as it automatically covers any future allocations added anywhere in the call tree without requiring each caller to be aware of this constraint.
