CVE-2026-10671 User thread can re-initialize an in-use `k_pipe`, corrupting kernel wait queues (`CONFIG_USERSPACE`)

In Zephyr's kernel pipe implementation, the userspace syscall verifier zvrfykpipeinit in kernel/pipe.c used KSYSCALLOBJ which requires the kernel object to already be initialized instead of KSYSCALLOBJNEVERINIT which rejects an already-initialized object. As a result, on CONFIGUSERSPACE builds an...

CVE-2026-53242 ALSA: PCM: Fix wait queue list corruption in snd_pcm_drain() on linked streams

In the Linux kernel, the following vulnerability has been resolved: ALSA: PCM: Fix wait queue list corruption in sndpcmdrain on linked streams sndpcmdrain uses initwaitqueueentry which does not clear entry.prev/next, and addwaitqueue with a conditional removewaitqueue that is skipped when tocheck...

CVE-2026-53242

CVE-2026-53242 affects the Linux kernel ALSA PCM path (snd_pcm_drain) on linked streams. The bug arises from wait queue handling: init_waitqueue_entry does not clear prev/next and add_wait_queue/remove_wait_queue sequencing can leave an orphaned wait entry on an old sleep queue after UNLINK, caus...
