CVE-2026-121412
FreeRDP 3.0.0 before 3.32.2 Proxy Memory Exhaustion via DVC Reassembly
Description
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.
