Local code execution via use-after-free
Published Jul 8, 2025 · Updated Feb 26, 2026
Use-after-free in Microsoft MPEG-2 Video Extension allows local users to execute code via unspecified local interaction. Microsoft identifies the flaw class but has not disclosed the freed object, dereference site, or exact input that triggers stale-memory access. Low-privileged local access is required, and successful exploitation runs code in the affected user's security context.
