FreeRDP 2.1.0 before 3.32.0 contains a use-after-free vulnerability in the static rdpsnd channel disconnect path, which frees audio formats and device without joining play_thread. A malicious RDP server can disconnect while asynchronous Wave2 playback processes queued PDUs, causing the client to read freed heap memory and crash.
