Frequently Asked Questions
What condition must an attacker meet to exploit this issue?
The attacker must first compromise the Chrome renderer process. From that position, a crafted HTML page can potentially be used to execute code outside Chrome's sandbox.
Which Chrome versions are affected?
Google Chrome versions prior to 153.0.8010.47 are affected. Updating to 153.0.8010.47 or later addresses the vulnerable version range described.
Is visiting a crafted page alone sufficient for exploitation?
The available information states that the renderer process must already be compromised. It does not say that merely visiting a crafted HTML page is sufficient on its own.
