Local privilege escalation via freed-memory reuse
Published Apr 8, 2025 · Updated Aug 10, 2026
Use-after-free in Windows Digital Media on affected Windows releases allows local users with low privileges to elevate privileges. Microsoft has not disclosed the affected function or object-lifetime error beyond identifying reuse of freed memory in Windows Digital Media. A local authenticated foothold is required; successful exploitation grants higher-privileged code execution with host-wide data and service impact.
