      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: aloop: Fix peer runtime UAF during format-change stop\n\nloopback_check_format() may stop the capture side when playback starts\nwith parameters that no longer match a running capture stream. Commit\n826af7fa62e3 (\"ALSA: aloop: Fix racy access at PCM trigger\") moved\nthe peer lookup under cable->lock, but the actual snd_pcm_stop() still\nruns after dropping that lock.\n\nA concurrent close can clear the capture entry from cable->streams[] and\ndetach or free its runtime while the playback trigger path still holds a\nstale peer substream pointer.\n\nKeep a per-cable count of in-flight peer stops before dropping\ncable->lock, and make free_cable() wait for those stops before\ndetaching the runtime. This preserves the existing behavior while\nmaking the peer runtime lifetime explicit.",
