Description OSIDB Bzimport 2026-02-09 20:01:44 UTC 
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, video_timer can send client notifications after the control channel is closed, dereferencing a freed callback and triggering a use after free. This vulnerability is fixed in 3.22.0.
