Description OSIDB Bzimport 2026-11-03 17:33:26 UTC 
FreeRDP before 3.32.2 contains a cross-thread use-after-free vulnerability in the freerdp-proxy dyn-channel-dump module during session teardown. A malicious RDP target can send dynamic channel data while the front client disconnects, letting the client thread read freed ChannelData and crash the proxy process.
