CVE-2026-109257

A flaw was found in FreeRDP. A remote attacker using a specially crafted Remote Desktop Protocol (RDP) client can request NSCodec compression with large display dimensions to trigger a memory allocation failure on the server. Because the server fails to properly clear memory pointers during error handling, this condition causes a double-free memory error during session cleanup. Consequently, an attacker can crash the server process, resulting in a Denial of Service (DoS).
