Which Chrome versions need to be updated?

Google Chrome versions before 155.0.8059.79 are affected. Updating to 155.0.8059.79 or later addresses the vulnerable version range described.

3

Are users protected if they do not interact with attacker-controlled content?

The described attack requires social engineering involving a crafted HTML page, in addition to prior renderer-process compromise. The provided information does not describe exploitation without those conditions.
