Frequently Asked Questions

1

What Chrome version includes the fix?

Google Chrome 152.0.7977.65 and later are not described as affected. Versions prior to 152.0.7977.65 are affected.

2

Does exploitation require more than convincing a user to load a crafted HTML page?

Yes. The attacker must already have compromised the renderer process; the crafted HTML page is used in that context to potentially execute code outside the sandbox.
