UpdatedIn the Linux kernel, the following vulnerability has been resolved: time/namespace: Validate nanosecond field in proc_timens_set_offset() The function validates tv_sec to be within [-KTIME_SEC_MAX, KTIME_SEC_MAX] but never validates that tv_nsec is within the valid range of [0, NSEC_PER_SEC-1] before using it in timespec64_add(). timespec64_add() expects both timespec64 structures to have norma
UpdatedIn the Linux kernel, the following vulnerability has been resolved: clk: qcom: gdsc: tear down per-domain genpds in gdsc_unregister() gdsc_unregister() removes the OF provider entry and tears down the parent/subdomain wiring, but never calls pm_genpd_remove() on the individual generic_pm_domain structures registered by gdsc_init(): void gdsc_unregister(struct gdsc_desc *desc) { struct devic
UpdatedIn the Linux kernel, the following vulnerability has been resolved: bpf: Reject writes through untrusted BTF pointers check_ptr_to_btf_access() lets program-type btf_struct_access callbacks validate writes before the default BTF access path rejects non-read accesses. That bypasses the read-only policy for untrusted BTF pointers created by helpers such as bpf_rdonly_cast(). Reject non-read acces
UpdatedIn the Linux kernel, the following vulnerability has been resolved: staging: media: ipu7: fix pm_runtime refcount leak in ipu7_resume() ipu7_resume() calls pm_runtime_get_sync() before resuming the device. If the runtime PM resume fails, the usage count remains incremented, but the error path returns without dropping the reference. Use pm_runtime_resume_and_get() instead, which balances the usa
UpdatedIn the Linux kernel, the following vulnerability has been resolved: thermal/drivers/rcar: Fix error checking in probe() This code accidentally calls thermal_zone_device_enable() before checking whether thermal_zone_device_register_with_trips() failed. Move the call until later to avoid an error pointer dereference of "priv->zone". The driver works differently depending on if we are using OF th
UpdatedIn the Linux kernel, the following vulnerability has been resolved: usb: gadget: r8a66597: avoid double free of ep0_req in probe error path If usb_add_gadget_udc() fails, r8a66597_probe() jumps to err_add_udc and frees ep0_req, then falls through to clean_up2 where ep0_req is freed again when it is non-NULL. Remove the redundant free from err_add_udc and keep the cleanup in clean_up2 so the req
UpdatedIn the Linux kernel, the following vulnerability has been resolved: udf: Mark LVID buffer as uptodate before marking it dirty When an I/O error occurs while writing the Logical Volume Integrity Descriptor (LVID) buffer to the block device, the block layer's completion handler (`end_buffer_write_sync()`) clears the `BH_Uptodate` flag on the buffer. However, the buffer still contains valid LVID da
UpdatedIn the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/mes: Fix hung_queue_db_array loop limit for multi-XCC The loop iterated only AMDGPU_MAX_MES_PIPES times, leaving entries uninitialized for multi-XCC GPUs.

UpdatedIn 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 p
UpdatedIn the Linux kernel, the following vulnerability has been resolved: bpf: Fix use-after-free on mm_struct in bpf_find_vma() bpf_find_vma() reads task->mm and calls mmap_read_trylock(mm) without holding a reference on the mm. On a foreign task, a concurrent exit_mm() can free the mm_struct between the lockless read and the trylock, resulting in a use-after-free. mm_struct is not SLAB_TYPESAFE_BY_R
Updated- CVE-2026-93136: bus: mhi: ep: Fix device refcount leak in the error path of MHI device creation Unscored
In the Linux kernel, the following vulnerability has been resolved: bus: mhi: ep: Fix device refcount leak in the error path of MHI device creation mhi_ep_create_device() takes one device reference for the UL channel and another for the DL channel after allocating the transfer device. These references are normally released by mhi_ep_destroy_device() before the device itself is removed. If dev_s
Updated In the Linux kernel, the following vulnerability has been resolved: bpf: Reject programs with inlined helpers if JIT is not available When an architecture (such as LoongArch, ARM64, and RISC-V) implements bpf_jit_inlines_helper_call(), the verifier skips rewriting the helper call offset (insn->imm) in bpf_do_misc_fixups(). This is because the helper is expected to be inlined by the JIT compiler
UpdatedIn the Linux kernel, the following vulnerability has been resolved: printk: Fix possible console use-after-free When emitting a record via legacy printing, it is possible that a handover to another legacy printing context occurs. When a context has performed a handover, the console SRCU read lock is released and the pointer to the console struct might now be invalid. Therefore, after calling nbc
UpdatedIn the Linux kernel, the following vulnerability has been resolved: ACPI: RISC-V: Check acpi_get_handle() status in riscv_acpi_add_prt_dep() In riscv_acpi_add_prt_dep(), the acpi_get_handle() call can fail which would leave link_handle uninitialized. Fix it by checking the acpi_get_handle() return status and skip the entry if it fails.
UpdatedIn the Linux kernel, the following vulnerability has been resolved: ACPI: RISC-V: Fix riscv_acpi_add_prt_dep() loop handling The loop in riscv_acpi_add_prt_dep() includes error conditions that are handled in a dubious - if not outright wrong - way, by continuining the loop (which skips and misses the entry pointer update to point to the next entry). Rewrite the loop as a for loop (that handles

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Avoid reprocessing the current packet after the QP enters the error state When do_complete() finds the QP in the error state it returns RESPST_CHK_RESOURCE. Before commit 49dc9c1f0c7e ("RDMA/rxe: Cleanup reset state handling in rxe_resp.c") this was the flush loop: check_resource() had an error-state branch that fetch
Updated In the Linux kernel, the following vulnerability has been resolved: crash_dump: release keyring reference at the correct time restore_dm_crypt_keys_to_thread_keyring() gets a reference to the user keyring before restoring the saved dm-crypt keys. The same keyring reference is then passed to add_key_to_keyring() for each saved key, but add_key_to_keyring() drops that reference on every call. Thi
UpdatedIn the Linux kernel, the following vulnerability has been resolved: esp: do not unref managed frag pages in esp_ssg_unref() esp_ssg_unref() releases the page references held on the source scatterlist after the AEAD operation completes. It calls skb_page_unref() on every frag page for an out-of-place transform (req->src != req->dst), and in the error path of esp_output_tail() (already_unref == t
UpdatedIn the Linux kernel, the following vulnerability has been resolved: RDMA/rvt: Return NULL after port allocation failure rvt_alloc_device() deallocates the IB device when its port array cannot be allocated but then returns the pointer to the released allocation. Callers treat any non-NULL value as valid and dereference it, resulting in a use-after-free. Return NULL immediately after deallocation
UpdatedIn the Linux kernel, the following vulnerability has been resolved: RDMA/hfi1: Preserve unit 0 on allocation failure hfi1_free_devdata() assumes that the device was inserted into the unit table and unconditionally erases dd->unit. If xa_alloc_irq() fails, the zero-initialized unit remains zero, so full cleanup can remove an unrelated device from index 0. Release only the rdmavt allocation and r
UpdatedIn the Linux kernel, the following vulnerability has been resolved: RDMA/hfi1: Free RX data on late probe failure hfi1_init_dd() allocates the shared AIP/VNIC RX support before returning. If hfi1_init() or hfi1_register_ib_device() later fails, init_one() tears down the device data without calling hfi1_free_rx(). This leaks netdev_rx and its dummy netdev. Free the RX support after IB unregistra
UpdatedIn the Linux kernel, the following vulnerability has been resolved: media: v4l2-async: Unregister sub-device if asc_list is empty When my em28xx USB device that uses the i2c tvp5150 driver is disconnected, it crashes. The cause is that the tvp5150 i2c module uses v4l2_async, but the em28xx driver does not since it predates v4l2_async. In that corner case sd->asc_list is empty, so v4l2_async_un
UpdatedIn the Linux kernel, the following vulnerability has been resolved: fs/resctrl: Prevent use-after-free in rdtgroup_kn_put() A struct rdtgroup is reference counted via rdtgroup::waitcount. Callers that need the structure to remain valid across a sleep (while waiting on acquiring rdtgroup_mutex) take a reference with rdtgroup_kn_get() and release it with rdtgroup_kn_put(). The release path is int
UpdatedIn the Linux kernel, the following vulnerability has been resolved: fs/resctrl: Fix UAF from worker threads when domains are removed The mbm_handle_overflow() and cqm_handle_limbo() workers read event counters and may sleep while doing so. They are scheduled via delayed_work embedded in struct rdt_l3_mon_domain. Architecture allocates and frees these domains from CPU hotplug callbacks under cpus
UpdatedIn the Linux kernel, the following vulnerability has been resolved: rpmsg: glink: fix deadlock in endpoint destroy during driver detach During driver detach, the device core holds the device mutex throughout the driver's remove callback chain. When the rpmsg endpoint is destroyed as part of that teardown, the GLINK endpoint destroy implementation attempts to unregister the underlying rpmsg devi
UpdatedIn the Linux kernel, the following vulnerability has been resolved: cxl/mbox: Break poison list loop on an empty payload A device that returns count == 0 with CXL_POISON_FLAG_MORE set on every iteration never advances nr_records, so the max_errors guard never trips and the do/while loops forever while holding poison.mutex. That hangs the sysfs-triggered scan thread and blocks all subsequent pois
UpdatedIn the Linux kernel, the following vulnerability has been resolved: cxl/features: Serialize multi-part Get/Set Feature transfers A Get or Set Feature payload larger than the mailbox payload size is split into several mailbox commands. mbox_mutex only serializes individual mailbox commands and is dropped between iterations of these loops. Nothing serializes the multi-part transfer as a whole. cxl
UpdatedIn the Linux kernel, the following vulnerability has been resolved: hfsplus: validate thread record before delete key rebuild hfsplus_delete_cat() is called with str == NULL when the last open reference to an unlinked HFS+ hardlink backing inode is closed. In that case, the function finds the catalog thread by CNID and rebuilds the catalog key from thread.nodeName. That reconstruction path read
UpdatedIn the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix dp_link_peer dangling references on AP vdev rollback ath12k_mac_vdev_create() for an AP vdev creates the bss self-peer via ath12k_peer_create(), which finishes by calling ath12k_dp_link_peer_assign() to publish the dp_link_peer in the dp_hw->dp_peers[peerid_index] RCU table, in the dp_peer's link_peers[] array,
UpdatedIn the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Publish channel state before callbacks Transport setup can enable callbacks before the setup routine returns. mailbox_chan_setup() registers the mailbox client with mbox_request_channel(), and the mailbox controller startup path can enable interrupt delivery before SCMI mailbox channel state has been publishe
UpdatedIn 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 register
UpdatedIn the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Quiesce notifications before teardown scmi_notification_exit() clears and releases the notification instance, but transport callbacks can still deliver incoming notifications until the TX/RX channels are freed. During remove, an RX interrupt in that window can enter scmi_notify() while notification state is b
UpdatedIn the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Clean up channels on setup failure scmi_channels_setup() can fail after the common BASE channel or earlier protocol channels have already been registered in the TX/RX IDRs. Route this failure through the existing channel cleanup label so the transport channels, transport devices and IDR state created before
