The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ALSA: aloop: Fix peer runtime UAF during format-change stop loopback_check_format() may stop the capture     side when playback starts with parameters that no longer match a running capture stream. Commit     826af7fa62e3 (ALSA: aloop: Fix racy access at PCM trigger) moved the peer lookup under cable->lock, but     the actual snd_pcm_stop() still runs after dropping that lock. A concurrent close can clear the capture     entry from cable->streams[] and detach or free its runtime while the playback trigger path still holds a     stale peer substream pointer. Keep a per-cable count of in-flight peer stops before dropping cable->lock,     and make free_cable() wait for those stops before detaching the runtime. This preserves the existing     behavior while making the peer runtime lifetime explicit. (CVE-2026-46090)

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