CVE-2025-32710Network attack vector

Unauthenticated code execution via RD Gateway race

Published Jun 10, 2025 · Updated Feb 20, 2026

Use-after-free in Microsoft Windows Remote Desktop Services allows remote attackers to execute code through an RD Gateway connection. A connection attempt to a server with the RD Gateway role can win a race that leaves Remote Desktop Services using freed memory. Exploitation is unauthenticated and requires winning the race; successful memory corruption grants code execution on the server.
