Resource exhaustion in Freerdp
CVE-2026-121412
FreeRDP from 3.0.0 before 3.32.2 contains an uncontrolled resource consumption vulnerability in the proxy that lets connected clients retain heap memory via intercepted DVC message reassembly. Attackers can declare a large DATA_FIRST length and keep sending fragments without completing the message, growing proxy memory proportional to traffic and degrading service.
