Local privilege escalation via double free
Published Sep 8, 2026 · Updated Sep 9, 2026
A double-free flaw in Microsoft Remote Desktop Gateway Service allows local users with existing access to elevate privileges on affected Windows systems. Microsoft identifies the service and memory-management error but has not published the responsible function, object lifetime, or triggering operation. Exploitation requires low privileges, no user interaction, and a high-complexity local path; successful exploitation grants elevated control of the system.
