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 snd_pcm_drain() on linked streams snd_pcm_drain() uses     init_waitqueue_entry which does not clear entry.prev/next, and add_wait_queue with a conditional     remove_wait_queue that is skipped when to_check is no longer in the group after concurrent UNLINK. The     orphaned wait entry remains on the unlinked substream sleep queue. On the next drain iteration,     add_wait_queue adds the entry to a new queue while still linked on the old one, corrupting both lists. A     subsequent wake_up dereferences NULL at the func pointer (mapped from the spinlock at offset 0 of the     misinterpreted wait_queue_head_t), causing a kernel panic. Replace     init_waitqueue_entry/add_wait_queue/conditional remove_wait_queue with init_wait_entry/prepare_to_wait/     finish_wait. init_wait_entry clears prev/next via INIT_LIST_HEAD on each iteration and sets     autoremove_wake_function which auto-removes the entry on wake-up. finish_wait safely handles both the     already-removed and still-queued cases. (CVE-2026-53242)

Note that Nessus relies on the presence of the package as reported by the vendor.
