Local privilege escalation via use-after-free
Published Jul 8, 2025 · Updated Feb 26, 2026
Use after free in Microsoft's Universal Print Management Service allows local users with existing access to elevate privileges on affected Windows systems. Microsoft identifies the service but has not published the affected function, object-lifetime error, or trigger that accesses freed memory. Successful exploitation requires low-privilege local access and grants control beyond the original security boundary.
