Code execution via use-after-free
Published Apr 8, 2025 · Updated Aug 10, 2026
Use-after-free in Microsoft Office allows local users to execute code after a targeted user interacts with malicious content. Microsoft has not disclosed the affected Office component, the freed object, or the operation that later dereferences stale memory. Exploitation requires user interaction and executes code in the affected user's context; no privilege is required before that interaction.
