Local code execution via use-after-free
Published Apr 14, 2026 · Updated Apr 14, 2026
Use-after-free in Microsoft Office allows local users to execute code through an undisclosed vulnerable memory-lifecycle operation. Microsoft has not published the affected component, freed object, or operation that later reuses the stale reference. Exploitation requires local access but no authentication or user interaction, and code runs in the affected Office process context.
