Local privilege escalation via use-after-free
Published Sep 10, 2024 · Updated Aug 10, 2026
Use-after-free in the Win32 kernel subsystem in affected Microsoft Windows releases allows local users to elevate privileges. Microsoft identifies the weakness class but has not disclosed the affected object, lifetime error, or trigger that reuses freed memory. Exploitation requires local low-privilege access and no user interaction; successful exploitation elevates privileges on the same machine.
