| In the Linux kernel, the following vulnerability has been resolved: irqchip/mchp-eic: Fix error code in mchp_eic_domain_alloc() If irq_domain_translate_twocell() sets "hwirq" to >= MCHP_EIC_NIRQ (2) then it results in an out of bounds access. The code checks for invalid values, but doesn't set the error code. Return -EINVAL in that case, instead of returning success. | ||||

| CVE-2025-68205 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: hda/hdmi: Fix breakage at probing nvhdmi-mcp driver After restructuring and splitting the HDMI codec driver code, each HDMI codec driver contains the own build_controls and build_pcms ops. A copy-n-paste error put the wrong entries for nvhdmi-mcp driver; both build_controls and build_pcms are swapped. Unfortunately both callbacks have the very same form, and the compiler didn't complain it, either. This resulted in a NULL dereference because the PCM instance hasn't been initialized at calling the build_controls callback. Fix it by passing the proper entries. | ||||
| CVE-2023-54324 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: dm: fix a race condition in retrieve_deps There's a race condition in the multipath target when retrieve_deps races with multipath_message calling dm_get_device and dm_put_device. retrieve_deps walks the list of open devices without holding any lock but multipath may add or remove devices to the list while it is running. The end result may be memory corruption or use-after-free memory access. See this description of a UAF with multipath_message(): https://listman.redhat.com/archives/dm-devel/2022-October/052373.html Fix this bug by introducing a new rw semaphore "devices_lock". We grab devices_lock for read in retrieve_deps and we grab it for write in dm_get_device and dm_put_device. | ||||

| 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. | ||||
| CVE-2025-68216 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Disable trampoline for kernel module function trace The current LoongArch BPF trampoline implementation is incompatible with tracing functions in kernel modules. This causes several severe and user-visible problems: * The `bpf_selftests/module_attach` test fails consistently. * Kernel lockup when a BPF program is attached to a module function [1]. * Critical kernel modules like WireGuard experience traffic disruption when their functions are traced with fentry [2]. Given the severity and the potential for other unknown side-effects, it is safest to disable the feature entirely for now. This patch prevents the BPF subsystem from allowing trampoline attachments to kernel module functions on LoongArch. This is a temporary mitigation until the core issues in the trampoline code for kernel module handling can be identified and fixed.

| CVE-2025-68240 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: nilfs2: avoid having an active sc_timer before freeing sci Because kthread_stop did not stop sc_task properly and returned -EINTR, the sc_timer was not properly closed, ultimately causing the problem [1] reported by syzbot when freeing sci due to the sc_timer not being closed. Because the thread sc_task main function nilfs_segctor_thread() returns 0 when it succeeds, when the return value of kthread_stop() is not 0 in nilfs_segctor_destroy(), we believe that it has not properly closed sc_timer. We use timer_shutdown_sync() to sync wait for sc_timer to shutdown, and set the value of sc_task to NULL under the protection of lock sc_state_lock, so as to avoid the issue caused by sc_timer not being properly shutdowned.

| In the Linux kernel, the following vulnerability has been resolved: mptcp: Fix proto fallback detection with BPF The sockmap feature allows bpf syscall from userspace, or based on bpf sockops, replacing the sk_prot of sockets during protocol stack processing with sockmap's custom read/write interfaces. ''' tcp_rcv_state_process() syn_recv_sock()/subflow_syn_recv_sock() tcp_init_transfer(BPF_SOCK_OPS_PASSIVE_ESTABLISHED_CB) bpf_skops_established <== sockops bpf_sock_map_update(sk) <== call bpf helper tcp_bpf_update_proto() <== update sk_prot ''' When the server has MPTCP enabled but the client sends a TCP SYN without MPTCP, subflow_syn_recv_sock() performs a fallback on the subflow, replacing the subflow sk's sk_prot with the native sk_prot. ''' subflow_syn_recv_sock() subflow_ulp_fallback() subflow_drop_ctx() mptcp_subflow_ops_undo_override() ''' Then, this subflow can be normally used by sockmap, which replaces the native sk_prot with sockmap's custom sk_prot. The issue occurs when the user executes accept::mptcp_stream_accept::mptcp_fallback_tcp_ops(). Here, it uses sk->sk_prot to compare with the native sk_prot, but this is incorrect when sockmap is used, as we may incorrectly set sk->sk_socket->ops. This fix uses the more generic sk_family for the comparison instead.
