CVE-2026-121393 is fixed in freerdp3 on 1 platform by DEBIAN-CVE-2026-121393 (version 3.32.2+dfsg-1), released November 4, 2026. It is not reported as exploited. Patch Radar priority: Routine.
FreeRDP from 3.0.0 before 3.32.2 contains a denial of service vulnerability that allows malicious RDP servers to abort clients built with verbose WinPR assertions by sending crafted RemoteFX region rectangles. Attackers can supply a rectangle with x set to 65535 alongside a SurfaceBits destination left of 1, triggering a 16-bit coordinate assertion in rfx_process_message that terminates the client process.
