SYSTEM privilege escalation via NTFS double-free
Published May 14, 2024 · Updated May 3, 2025
Double-free in Microsoft Windows NTFS allows local users to elevate privileges and execute arbitrary code with SYSTEM rights. The NTFS implementation releases the same memory allocation twice, but Microsoft has not identified the affected function or triggering input. Exploitation requires prior low-privileged local access; successful exploitation grants complete control of the affected system.
