CVE-2026-121963 is fixed in freerdp3 on 1 platform by DEBIAN-CVE-2026-121963 (version 3.32.2+dfsg-1), released November 5, 2026. It is not reported as exploited. Patch Radar priority: Routine.
FreeRDP before 3.32.2 contains a use-after-free vulnerability in the asynchronous dynamic rdpsnd channel that allows malicious RDP servers to trigger freed callback access by closing the channel with queued audio PDUs. Attackers can send a training PDU then close the channel so the playback thread reads the freed callback in rdpsnd_virtual_channel_write, crashing the client.
