Frequently Asked Questions

1

What prerequisite does an attacker need to exploit this issue?

The attacker must first compromise the Chrome renderer process. The issue is then triggered through a crafted HTML page and may allow code execution outside the sandbox.

2

Which Chrome on Android versions are affected?

Google Chrome on Android versions before 152.0.7977.65 are affected. Updating to 152.0.7977.65 or later addresses the affected version range.

3

Is this a standalone remote-code-execution issue against a normal browser session?

The description identifies renderer-process compromise as a prerequisite, so it is not described as a standalone initial compromise. Its impact is sandbox escape: arbitrary code execution outside the renderer sandbox after that prerequisite is met.
