Summary

FreeRDP 2.1.0 before 3.32.0 contains a use-after-free in the static rdpsnd channel disconnect path, which frees audio formats and device without joining play_thread (CWE-416). A malicious RDP server can disconnect while asynchronous Wave2 playback processes queued PDUs, causing the client to read freed heap memory and crash. CVSS 4.0 base score 6.0 (MEDIUM). Exploit code is referenced, but CISA has not added it to KEV.
