Mitigation

• Update Microsoft Edge to the latest version.
• Verify that the update includes the patch by checking the release notes in the Microsoft Edge update channel.
• For environments that cannot update immediately, consider disabling JavaScript or blocking untrusted sites until the patch is applied.

Detection

Monitor for abnormal browser crashes, memory corruption logs, or unexpected process termination. Use endpoint detection tools that flag use‑after‑free patterns in Chromium processes.

Response

Once updated, verify that the vulnerability is no longer present by attempting the known exploit test vectors provided by the Microsoft Security Response Center.
