Google has rolled out a security update for a critical Chrome zero-day vulnerability exploited in the wild.
Chrome generally applies the update automatically when users close and reopen the browser.
If the browser hasn't been closed in a while, users will see a colored icon indicating a pending update.
Mac users can also set up automatic browser updates.
Google has not yet revealed details about the attack, but urges users to update the browser as soon as possible.
Citizen Lab has recently detected two zero-day vulnerabilities affecting Apple devices.
