Privilege escalation via double free
Published Aug 11, 2026 · Updated Aug 25, 2026
Double free in Windows Autopilot in Microsoft Windows 11 24H2 through 26H1 allows local users to gain elevated privileges. Microsoft has not disclosed the specific function or code path, but the public record identifies a Windows Autopilot memory-management error that frees the same allocation twice and corrupts heap state. Exploitation requires local access and low privileges, and no public proof-of-concept or in-the-wild exploitation record was located in the retrieved authoritative sources as of August 19, 2026.
