Google releases critical security update for Chrome that fixes a 0-day vulnerability
Google released a new security update for its Chrome web browser that is fixing several security vulnerabilities in the browser. One of the security vulnerabilities is exploited in the wild, another received the highest severity rating of critical.
The update is being pushed out to all Chrome installations worldwide. It may take some time, days or even weeks, before the updates become available through the automatic update feature of the Chrome browser.
Desktop users may run manual checks for updates to protect their browser installations right away.
Select Menu > Help > About Google Chrome, or load chrome://settings/help to open the update page. Chrome displays the installed version, runs a check for updates, and will download and install any new version of the browser that it finds.
The fully updated desktop version is 96.0.4664.110. Android users can't force a manual check of the browser on their devices, as this is exclusively managed by Google Play.
Google lists five vulnerabilities that are fixed by the Chrome update on the official Releases Blog:
- [$NA] Critical CVE-2021-4098: Insufficient data validation in Mojo. Reported by Sergei Glazunov of Google Project Zero on 2021-10-26

Chrome users are advised to update their browsers as soon as possible to protect them against potential attacks.
