CVE-2026-57156

A flaw was found in FreeRDP clients. A remote attacker, acting as a malicious Remote Desktop Protocol (RDP) peer, could exploit an integer overflow vulnerability. This overflow occurs when the client processes a specially crafted RDP message, leading to the allocation of an undersized memory buffer. Consequently, the client attempts to write data beyond the boundaries of this buffer, which can result in arbitrary code execution or a denial of service.
