Local privilege escalation via memory object mishandling
Published May 21, 2020 · Updated Aug 19, 2026
Elevation of privilege in the Windows State Repository Service allows local users to run code with elevated rights on affected Windows releases. The service improperly handles objects in memory, but Microsoft has not disclosed the object type or the specific invalid memory operation. Exploitation requires a low-privileged user to run a specially crafted local application; success grants elevated code execution on the same system.
