Linux Distros Unpatched Vulnerability : CVE-2026-53242

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ALSA: PCM: Fix wait queue list corruption in sndpcmdrain on linked streams sndpcmdrain uses initwaitqueueentry which does not clear entry.prev/next, and...

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...

CVE-2026-43437

CVE-2026-43437 affects the Linux kernel ALSA PCM subsystem (snd_pcm_drain). The issue is a use-after-free in the drain path: during drain, runtime is reassigned to a linked stream’s runtime and after releasing the stream lock, runtime fields (no_period_wakeup, rate, buffer_size) are accessed with...
