A new alert has been issued, and anyone who uses Google Chrome to browse the internet, send emails, or watch hours of videos on YouTube should check their browser settings and restart things as soon as possible. The latest warning comes after Google confirmed it has fixed two serious security vulnerabilities in its popular browser software.

Of course, most of us are well aware of online bugs and gremlins, but what makes this new alert more worrying is that both flaws have been classified as zero-day vulnerabilities. This means cybercriminals had already discovered and were actively exploiting these weaknesses before the fixes were released.

The issues, identified as CVE-2026-3909 and CVE-2026-3910, have now been patched by Google’s Chrome engineers. However, users are protected only after installing the latest browser update. That means if you are running an older version of Chrome you could be vulnerable.

In its update notes, Google said it is aware that exploits for both vulnerabilities are already circulating online, making it important for users to update immediately.

To check whether your browser is up to date, open Chrome, click the menu bar, and select “About Google Chrome.” This page will show the version currently installed on your computer.

Users running Chrome version 146.0.7680.75/76 on Windows or Mac, or 146.0.7680.75 on Linux, already have the fix.

If you’re using an earlier version, you should install the update and relaunch the browser as soon as possible. The process typically takes less than a minute and ensures your system is protected from known attacks.

Google added that the updated Stable channel version is rolling out gradually to users over the coming days and weeks.

“We would also like to thank all security researchers that worked with us during the development cycle to prevent security bugs from ever reaching the stable channel,” the tech giant added.
