| In the Linux kernel, the following vulnerability has been resolved: net: mscc: ocelot: Fix use-after-free caused by cyclic delayed work The origin code calls cancel_delayed_work() in ocelot_stats_deinit() to cancel the cyclic delayed work item ocelot->stats_work. However, cancel_delayed_work() may fail to cancel the work item if it is already executing. While destroy_workqueue() does wait for all pending work items in the work queue to complete before destroying the work queue, it cannot prevent the delayed work item from being rescheduled within the ocelot_check_stats_work() function. This limitation exists because the delayed work item is only enqueued into the work queue after its timer expires. Before the timer expiration, destroy_workqueue() has no visibility of this pending work item. Once the work queue appears empty, destroy_workqueue() proceeds with destruction. When the timer eventually expires, the delayed work item gets queued again, leading to the following warning: workqueue: cannot queue ocelot_check_stats_work on wq ocelot-switch-stats WARNING: CPU: 2 PID: 0 at kernel/workqueue.c:2255 __queue_work+0x875/0xaf0 ...

The following diagram reveals the cause of the above warning: CPU 0 (remove) | CPU 1 (delayed work callback) mscc_ocelot_remove() | ocelot_deinit() | ocelot_check_stats_work() ocelot_stats_deinit() | cancel_delayed_work()| ... | queue_delayed_work() destroy_workqueue() | (wait a time) | __queue_work() //UAF The above scenario actually constitutes a UAF vulnerability. The ocelot_stats_deinit() is only invoked when initialization failure or resource destruction, so we must ensure that any delayed work items cannot be rescheduled. Replace cancel_delayed_work() with disable_delayed_work_sync() to guarantee proper cancellation of the delayed work item and ensure completion of any currently executing work before the workqueue is deallocated. A deadlock concern was considered: ocelot_stats_deinit() is called in a process context and is not holding any locks that the delayed work item might also need. Therefore, the use of the _sync() variant is safe here. This bug was identified through static analysis. To reproduce the issue and validate the fix, I simulated ocelot-swit ---truncated--- | ||||

| In the Linux kernel, the following vulnerability has been resolved: media: b2c2: Fix use-after-free causing by irq_check_work in flexcop_pci_remove The original code uses cancel_delayed_work() in flexcop_pci_remove(), which does not guarantee that the delayed work item irq_check_work has fully completed if it was already running.

| In the Linux kernel, the following vulnerability has been resolved: media: i2c: tc358743: Fix use-after-free bugs caused by orphan timer in probe The state->timer is a cyclic timer that schedules work_i2c_poll and delayed_work_enable_hotplug, while rearming itself. Using timer_delete() fails to guarantee the timer isn't still running when destroyed, similarly cancel_delayed_work() cannot ensure delayed_work_enable_hotplug has terminated if already executing.

Replace timer_delete() with timer_delete_sync() and cancel_delayed_work() with cancel_delayed_work_sync() to ensure proper termination of timer and work items before resource cleanup. This bug was initially identified through static analysis. For reproduction and testing, I created a functional emulation of the tc358743 device via a kernel module and introduced faults through the debugfs interface. | ||||

| In the Linux kernel, the following vulnerability has been resolved: media: v4l2-subdev: Fix alloc failure check in v4l2_subdev_call_state_try() v4l2_subdev_call_state_try() macro allocates a subdev state with __v4l2_subdev_state_alloc(), but does not check the returned value. If __v4l2_subdev_state_alloc fails, it returns an ERR_PTR, and that would cause v4l2_subdev_call_state_try() to crash. Add proper error handling to v4l2_subdev_call_state_try(). | ||||

| In the Linux kernel, the following vulnerability has been resolved: ice: ice_adapter: release xa entry on adapter allocation failure When ice_adapter_new() fails, the reserved XArray entry created by xa_insert() is not released. This causes subsequent insertions at the same index to return -EBUSY, potentially leading to NULL pointer dereferences. Reorder the operations as suggested by Przemek Kitszel: 1. Check if adapter already exists (xa_load) 2. Reserve the XArray slot (xa_reserve) 3. Allocate the adapter (ice_adapter_new) 4. Store the adapter (xa_store) | ||||

| In the Linux kernel, the following vulnerability has been resolved: bpf: prevent leak of lsm program after failed attach In [0], we added the ability to bpf_prog_attach LSM programs to cgroups, but in our validation to make sure the prog is meant to be attached to BPF_LSM_CGROUP, we return too early if the check fails. This results in lack of decrementing prog's refcnt (through bpf_prog_put) leaving the LSM program alive past the point of the expected lifecycle. This fix allows for the decrement to take place.

| CVE-2025-40181 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: x86/kvm: Force legacy PCI hole to UC when overriding MTRRs for TDX/SNP When running as an SNP or TDX guest under KVM, force the legacy PCI hole, i.e. memory between Top of Lower Usable DRAM and 4GiB, to be mapped as UC via a forced variable MTRR range. In most KVM-based setups, legacy devices such as the HPET and TPM are enumerated via ACPI. ACPI enumeration includes a Memory32Fixed entry, and optionally a SystemMemory descriptor for an OperationRegion, e.g. if the device needs to be accessed via a Control Method. If a SystemMemory entry is present, then the kernel's ACPI driver will auto-ioremap the region so that it can be accessed at will. However, the ACPI spec doesn't provide a way to enumerate the memory type of SystemMemory regions, i.e. there's no way to tell software that a region must be mapped as UC vs. WB, etc. As a result, Linux's ACPI driver always maps SystemMemory regions using ioremap_cache(), i.e. as WB on x86. The dedicated device drivers however, e.g. the HPET driver and TPM driver, want to map their associated memory as UC or WC, as accessing PCI devices using WB is unsupported. On bare metal and non-CoCO, the conflicting requirements "work" as firmware configures the PCI hole (and other device memory) to be UC in the MTRRs. So even though the ACPI mappings request WB, they are forced to UC- in the kernel's tracking due to the kernel properly handling the MTRR overrides, and thus are compatible with the drivers' requested WC/UC-. With force WB MTRRs on SNP and TDX guests, the ACPI mappings get their requested WB if the ACPI mappings are established before the dedicated driver code attempts to initialize the device. E.g. if acpi_init() runs before the corresponding device driver is probed, ACPI's WB mapping will "win", and result in the driver's ioremap() failing because the existing WB mapping isn't compatible with the requested WC/UC-. E.g. when a TPM is emulated by the hypervisor (ignoring the security implications of relying on what is allegedly an untrusted entity to store measurements), the TPM driver will request UC and fail: [ 1.730459] ioremap error for 0xfed40000-0xfed45000, requested 0x2, got 0x0 [ 1.732780] tpm_tis MSFT0101:00: probe with driver tpm_tis failed with error -12 Note, the '0x2' and '0x0' values refer to "enum page_cache_mode", not x86's memtypes (which frustratingly are an almost pure inversion; 2 == WB, 0 == UC). E.g. tracing mapping requests for TPM TIS yields: Mapping TPM TIS with req_type = 0 WARNING: CPU: 22 PID: 1 at arch/x86/mm/pat/memtype.c:530 memtype_reserve+0x2ab/0x460 Modules linked in: CPU: 22 UID: 0 PID: 1 Comm: swapper/0 Tainted: G W 6.16.0-rc7+ #2 VOLUNTARY Tainted: [W]=WARN Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 05/29/2025 RIP: 0010:memtype_reserve+0x2ab/0x460 __ioremap_caller+0x16d/0x3d0 ioremap_cache+0x17/0x30 x86_acpi_os_ioremap+0xe/0x20 acpi_os_map_iomem+0x1f3/0x240 acpi_os_map_memory+0xe/0x20 acpi_ex_system_memory_space_handler+0x273/0x440 acpi_ev_address_space_dispatch+0x176/0x4c0 acpi_ex_access_region+0x2ad/0x530 acpi_ex_field_datum_io+0xa2/0x4f0 acpi_ex_extract_from_field+0x296/0x3e0 acpi_ex_read_data_from_field+0xd1/0x460 acpi_ex_resolve_node_to_value+0x2ee/0x530 acpi_ex_resolve_to_value+0x1f2/0x540 acpi_ds_evaluate_name_path+0x11b/0x190 acpi_ds_exec_end_op+0x456/0x960 acpi_ps_parse_loop+0x27a/0xa50 acpi_ps_parse_aml+0x226/0x600 acpi_ps_execute_method+0x172/0x3e0 acpi_ns_evaluate+0x175/0x5f0 acpi_evaluate_object+0x213/0x490 acpi_evaluate_integer+0x6d/0x140 acpi_bus_get_status+0x93/0x150 acpi_add_single_object+0x43a/0x7c0 acpi_bus_check_add+0x149/0x3a0 acpi_bus_check_add_1+0x16/0x30 acpi_ns_walk_namespace+0x22c/0x360 acpi_walk_namespace+0x15c/0x170 acpi_bus_scan+0x1dd/0x200 acpi_scan_init+0xe5/0x2b0 acpi_init+0x264/0x5b0 do_one_i ---truncated--- | ||||
