Frequently Asked Questions

1

Which systems are exposed to this issue?

Google Chrome installations on Windows with versions earlier than 155.0.8059.39 are affected. Exploitation requires the attacker to be adjacent on the network.

2

What does an attacker need to exploit it?

The attacker does not need privileges or user interaction, but must be able to send crafted network traffic from an adjacent network position. The attack has high complexity and can disclose sensitive information.

3

How can I determine whether a Chrome installation is affected?

Check the installed Google Chrome version on Windows. Versions prior to 155.0.8059.39 are affected; updating to that version or later addresses the affected version range.
