Frequently Asked Questions

1

Who is exposed to this issue?

Android devices running Google Chrome before 155.0.8059.39 are affected. Exploitation requires a malicious or otherwise attacker-controlled app to already be installed on the device.

2

Does exploitation require user interaction or special attacker privileges?

The attacker does not need Chrome privileges or remote network access, but the issue relies on social engineering and a co-installed app. The CVSS vector indicates no user interaction is required once those conditions are in place.

3

What is the impact if exploitation succeeds?

A local attacker may obtain sensitive information. The provided CVSS assessment indicates confidentiality impact only, with no integrity or availability impact.

4

What should teams do to remediate this?

Update Google Chrome on Android to version 155.0.8059.39 or later. If updating cannot happen immediately, reduce exposure by identifying and removing untrusted co-installed applications, particularly where social-engineering delivery is plausible.
