Description OSIDB Bzimport 2026-02-09 20:01:42 UTC 
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, AUDIN format renegotiation frees the active format list while the capture thread continues using audin->format, leading to a use after free in audio_format_compatible. This vulnerability is fixed in 3.22.0.
