Frequently Asked Questions
What does an attacker need in order to exploit this issue?
The attacker must already have compromised the Chrome renderer process. They can then use a crafted HTML page to potentially execute arbitrary code outside Chrome’s sandbox.
Which systems and versions are affected?
The issue affects Google Chrome on macOS before version 153.0.8010.47.
Does visiting a crafted page alone compromise an otherwise intact browser?
The provided information describes exploitation after the renderer process has already been compromised. It does not state that a crafted HTML page alone can trigger the issue in an otherwise uncompromised renderer.
