Code execution via use-after-free memory access
Published Mar 11, 2025 · Updated Feb 13, 2026
Use-after-free in Microsoft Office Word allows context-dependent attackers to execute code locally after user interaction. Microsoft identifies a freed-memory access but does not disclose the affected parser, object-lifetime error, or crafted input format. Exploitation requires user interaction with attacker-controlled content, and successful exploitation runs code in the user's context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
