Local code execution via global-memory use-after-free
Published Oct 14, 2025 · Updated Feb 26, 2026
Use-after-free in Microsoft Windows Inbox COM Objects allows local users to execute code after required user interaction. The component accesses global-memory storage after its lifetime ends, but Microsoft has not identified the object, API, or input path involved. Exploitation has high attack complexity and requires user interaction; success runs attacker-controlled code on the affected system.

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.
- Affected versionversion=10.0.10240.0 <10.0.10240.21161
