Details

PulseAudio in Ubuntu contains additional functionality to mediate audio
recording for snap packages and it was discovered that this functionality
did not mediate PulseAudio module unloading. An attacker-controlled snap
with only the audio-playback interface connected could exploit this to
bypass access controls and record audio.
