Local privilege escalation via use-after-free
Published Nov 11, 2025 · Updated Feb 26, 2026
Use-after-free in Microsoft Windows Broadcast DVR User Service allows local users with low privileges to elevate privileges. Microsoft has not published the freed object's identity, the code path that reuses it, or how attacker-controlled activity reaches the stale reference. Successful exploitation requires prior local low-privileged access and yields elevated execution on the affected Windows host.
