| CVE-2025-40035 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: Input: uinput - zero-initialize uinput_ff_upload_compat to avoid info leak Struct ff_effect_compat is embedded twice inside uinput_ff_upload_compat, contains internal padding. In particular, there is a hole after struct ff_replay to satisfy alignment requirements for the following union member. Without clearing the structure, copy_to_user() may leak stack data to userspace. Initialize ff_up_compat to zero before filling valid fields. | ||||

| In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: fix possible map leak in fastrpc_put_args copy_to_user() failure would cause an early return without cleaning up the fdlist, which has been updated by the DSP. This could lead to map leak. Fix this by redirecting to a cleanup path on failure, ensuring that all mapped buffers are properly released before returning. | ||||

The pointer is treated as a 32bit value and sign extend to 64bit in epilogue. This behavior is right for most bpf prog types but wrong for struct ops which requires LoongArch ABI. So let's sign extend struct ops return values according to the LoongArch ABI ([1]) and return value spec in function model.

| CVE-2025-40043 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: nfc: nci: Add parameter validation for packet data Syzbot reported an uninitialized value bug in nci_init_req, which was introduced by commit 5aca7966d2a7 ("Merge tag 'perf-tools-fixes-for-v6.17-2025-09-16' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools"). This bug arises due to very limited and poor input validation that was done at nic_valid_size(). This validation only validates the skb->len (directly reflects size provided at the userspace interface) with the length provided in the buffer itself (interpreted as NCI_HEADER). This leads to the processing of memory content at the address assuming the correct layout per what opcode requires there. This leads to the accesses to buffer of `skb_buff->data` which is not assigned anything yet. Following the same silent drop of packets of invalid sizes at `nic_valid_size()`, add validation of the data in the respective handlers and return error values in case of failure. Release the skb if error values are returned from handlers in `nci_nft_packet` and effectively do a silent drop Possible TODO: because we silently drop the packets, the call to `nci_request` will be waiting for completion of request and will face timeouts. These timeouts can get excessively logged in the dmesg. A proper handling of them may require to export `nci_request_cancel` (or propagate error handling from the nft packets handlers). | ||||

| In the Linux kernel, the following vulnerability has been resolved: io_uring/waitid: always prune wait queue entry in io_waitid_wait() For a successful return, always remove our entry from the wait queue entry list. Previously this was skipped if a cancelation was in progress, but this can race with another invocation of the wait queue entry callback. | ||||
| CVE-2025-40050 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Skip scalar adjustment for BPF_NEG if dst is a pointer In check_alu_op(), the verifier currently calls check_reg_arg() and adjust_scalar_min_max_vals() unconditionally for BPF_NEG operations. However, if the destination register holds a pointer, these scalar adjustments are unnecessary and potentially incorrect. This patch adds a check to skip the adjustment logic when the destination register contains a pointer. | ||||

| In the Linux kernel, the following vulnerability has been resolved: vhost: vringh: Fix copy_to_iter return value check The return value of copy_to_iter can't be negative, check whether the copied length is equal to the requested length instead of checking for negative values. | ||||
| CVE-2025-40061 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix race in do_task() when draining When do_task() exhausts its iteration budget (!ret), it sets the state to TASK_STATE_IDLE to reschedule, without a secondary check on the current task->state. This can overwrite the TASK_STATE_DRAINING state set by a concurrent call to rxe_cleanup_task() or rxe_disable_task(). While state changes are protected by a spinlock, both rxe_cleanup_task() and rxe_disable_task() release the lock while waiting for the task to finish draining in the while(!is_done(task)) loop. The race occurs if do_task() hits its iteration limit and acquires the lock in this window. The cleanup logic may then proceed while the task incorrectly reschedules itself, leading to a potential use-after-free. This bug was introduced during the migration from tasklets to workqueues, where the special handling for the draining case was lost. Fix this by restoring the original pre-migration behavior. If the state is TASK_STATE_DRAINING when iterations are exhausted, set cont to 1 to force a new loop iteration. This allows the task to finish its work, so that a subsequent iteration can reach the switch statement and correctly transition the state to TASK_STATE_DRAINED, stopping the task as intended. | ||||
| CVE-2025-40063 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: crypto: comp - Use same definition of context alloc and free ops In commit 42d9f6c77479 ("crypto: acomp - Move scomp stream allocation code into acomp"), the crypto_acomp_streams struct was made to rely on having the alloc_ctx and free_ctx operations defined in the same order as the scomp_alg struct. But in that same commit, the alloc_ctx and free_ctx members of scomp_alg may be randomized by structure layout randomization, since they are contained in a pure ops structure (containing only function pointers). If the pointers within scomp_alg are randomized, but those in crypto_acomp_streams are not, then the order may no longer match. This fixes the problem by removing the union from scomp_alg so that both crypto_acomp_streams and scomp_alg will share the same definition of alloc_ctx and free_ctx, ensuring they will always have the same layout. | ||||

| In the Linux kernel, the following vulnerability has been resolved: RISC-V: KVM: Write hgatp register with valid mode bits According to the RISC-V Privileged Architecture Spec, when MODE=Bare is selected,software must write zero to the remaining fields of hgatp. We have detected the valid mode supported by the HW before, So using a valid mode to detect how many vmid bits are supported. | ||||
| CVE-2025-39998 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: scsi: target: target_core_configfs: Add length check to avoid buffer overflow A buffer overflow arises from the usage of snprintf to write into the buffer "buf" in target_lu_gp_members_show function located in /drivers/target/target_core_configfs.c. This buffer is allocated with size LU_GROUP_NAME_BUF (256 bytes). snprintf(...) formats multiple strings into buf with the HBA name (hba->hba_group.cg_item), a slash character, a devicename (dev-> dev_group.cg_item) and a newline character, the total formatted string length may exceed the buffer size of 256 bytes. Since snprintf() returns the total number of bytes that would have been written (the length of %s/%sn ), this value may exceed the buffer length (256 bytes) passed to memcpy(), this will ultimately cause function memcpy reporting a buffer overflow error. An additional check of the return value of snprintf() can avoid this buffer overflow. | ||||
| CVE-2025-39994 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: media: tuner: xc5000: Fix use-after-free in xc5000_release The original code uses cancel_delayed_work() in xc5000_release(), which does not guarantee that the delayed work item timer_sleep has fully completed if it was already running. This leads to use-after-free scenarios where xc5000_release() may free the xc5000_priv while timer_sleep is still active and attempts to dereference the xc5000_priv. A typical race condition is illustrated below: CPU 0 (release thread) | CPU 1 (delayed work callback) xc5000_release() | xc5000_do_timer_sleep() cancel_delayed_work() | hybrid_tuner_release_state(priv) | kfree(priv) | | priv = container_of() // UAF Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure that the timer_sleep is properly canceled before the xc5000_priv memory is deallocated. A deadlock concern was considered: xc5000_release() is called in a process context and is not holding any locks that the timer_sleep work item might also need. Therefore, the use of the _sync() variant is safe here. This bug was initially identified through static analysis. [hverkuil: fix typo in Subject: tunner -> tuner] | ||||

Specifically, the fields usbdev_intf0 and usbdev_intf1 are not protected by the users counter (ictx->users). During probe, imon_init_intf0 or imon_init_intf1 increments the usb_device reference count depending on the interface.

| In the Linux kernel, the following vulnerability has been resolved: tracing/osnoise: Fix slab-out-of-bounds in _parse_integer_limit() When config osnoise cpus by write() syscall, the following KASAN splat may be observed: BUG: KASAN: slab-out-of-bounds in _parse_integer_limit+0x103/0x130 Read of size 1 at addr ffff88810121e3a1 by task test/447 CPU: 1 UID: 0 PID: 447 Comm: test Not tainted 6.17.0-rc6-dirty #288 PREEMPT(voluntary) Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x55/0x70 print_report+0xcb/0x610 kasan_report+0xb8/0xf0 _parse_integer_limit+0x103/0x130 bitmap_parselist+0x16d/0x6f0 osnoise_cpus_write+0x116/0x2d0 vfs_write+0x21e/0xcc0 ksys_write+0xee/0x1c0 do_syscall_64+0xa8/0x2a0 entry_SYSCALL_64_after_hwframe+0x77/0x7f </TASK> This issue can be reproduced by below code: const char *cpulist = "1"; int fd=open("/sys/kernel/debug/tracing/osnoise/cpus", O_WRONLY); write(fd, cpulist, strlen(cpulist)); Function bitmap_parselist() was called to parse cpulist, it require that the parameter 'buf' must be terminated with a '\0' or '\n'. Fix this issue by adding a '\0' to 'buf' in osnoise_cpus_write(). | ||||
