Local privilege escalation via memory object mishandling
Published May 21, 2020 · Updated Aug 19, 2026
Elevation of privilege in Microsoft Windows State Repository Service allows local users to run arbitrary code in an elevated context. The service improperly handles objects in memory, but Microsoft has not disclosed the affected code path or exact memory-safety operation. Exploitation requires a local user to run a specially crafted application, and successful exploitation executes code with elevated privileges.
