CVE-2026-121405 is fixed in freerdp3 on 1 platform by DEBIAN-CVE-2026-121405 (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 fails to cap the OutputBufferLength in serial device-control IRP requests, allowing malicious servers to trigger excessive memory allocation. Attackers running a server with serial redirection can send an IRP_MJ_DEVICE_CONTROL request with IOCTL_USBPRINT_GET_1284_ID and a near-maximum length to exhaust client memory.
