Local code execution via use-after-free
Published Jul 8, 2025 · Updated Feb 13, 2026
Use-after-free in Microsoft Office Word allows attackers to execute code locally when a user interacts with malicious content. Microsoft identifies freed-memory reuse in Word but has not published the affected parser, object lifetime error, or input format. Successful exploitation requires user interaction and runs code in the affected user's security context, enabling data access, alteration, or service interruption.
