It has been assigned CVE-2020-11931. Ubuntu's PulseAudio package is shipped with a custom "module-snap- policy" module intended to restrict snap confined clients from recording audio unless they have the "audio-record" plug connected. However, it does not restrict access to the "PA_COMMAND_UNLOAD_MODULE" command. This allows a snap that has only plugged "audio-playback" to request that PulseAudio unload the security policy module, which in turn makes it possible to record audio.
