Mitigation
- Ensure Microsoft Edge is updated to the latest version via Windows Update or the Microsoft Edge update channel.
- Verify the installed Edge version includes the Chromium patch (check the release notes or the About page).
- Apply any pending Windows security updates that bundle the latest Edge build.
