Security News > 2021 > December > Update Google Chrome to Patch New Zero-Day Exploit Detected in the Wild

Google has rolled out fixes for five security vulnerabilities in its Chrome web browser, including one which it says is being exploited in the wild, making it the 17th such weakness to be disclosed since the start of the year.
An anonymous researcher has been credited with discovering and reporting the flaw.
As it stands, it's not known how the weakness is being abused in real-world attacks, but the internet giant issued a terse statement that said, "It's aware of reports that an exploit for CVE-2021-4102 exists in the wild." This is done so in an attempt to ensure that a majority of users are updated with a fix and prevent further exploitation by other threat actors.
CVE-2021-4102 is the second use-after-free vulnerability in V8 the company has remediated in less than three months following reports of active exploitation, with the previous vulnerability CVE-2021-37975, also reported by an anonymous researcher, plugged in an update it shipped on September 30.
With this latest update, Google has addressed a record 17 zero-days in Chrome this year alone -.
Chrome users are recommended to update to the latest version for Windows, Mac, and Linux by heading to Settings > Help > 'About Google Chrome' to mitigate any potential risk of active exploitation.
