CVE-2026-121406 is fixed in freerdp3 on 1 platform by DEBIAN-CVE-2026-121406 (version 3.32.2+dfsg-1), released November 4, 2026. It is not reported as exploited. Patch Radar priority: Routine.
FreeRDP before 3.32.2 allows a client assertion abort because rdpgfx_on_data_received rejects only negative zgfx_decompress status and passes the resulting null output pointer to Stream_StaticConstInit. A malicious RDP server can send a zero-output ZGFX payload on the RDPGFX channel after session activation to terminate the client.
