  "details": "In the Linux kernel, the following vulnerability has been resolved:  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-\u003elock, but the actual snd_pcm_stop() still runs after dropping that lock.  A concurrent close can clear the capture entry from cable-\u003estreams[] 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-\u003elock, and make free_cable() wait for those stops before detaching the runtime. This preserves the existing behavior while making the peer runtime lifetime explicit.",
