Google Chrome 101 Security Alert for 3.2 Billion Users – Update Now

May 11 Update: This post was originally published on May 10

I spoke too soon when I reported yesterday that Google had confirmed a relatively rare update only for Android users of the Chrome browser. Windows, Linux and Mac users can no longer breathe easy and instead should now also check to see if their Chrome browsers are updated as soon as possible. Why the change? Because Google has now confirmed that billions of users of the world’s most popular web browser are affected by the latest security vulnerabilities.

A May 10 announcement by Prudhvikumar Bommana of the Google Chrome team confirmed that the same nine vulnerabilities affecting the Android security update warning actually applies to desktop browser on all platforms as well† Actually, there are a total of 13 security solutions, as I originally reported, but only nine CVE numbers have been assigned. It’s unclear at this point why there was a delay between the two updates that were confirmed, but I’ll try to find out and report back. While none of the vulnerabilities disclosed this time around are of the zero-day variety, meaning there’s no evidence that attackers are exploiting them yet, that’s no cause for complacency. Therefore, update your Chrome browser as soon as possible.

In the case of the desktop browser, this means going to the Help|About option in your Google Chrome menu. The update will be downloaded automatically if it is available to you. The full details can be found here but the most important thing to remember is to restart the browser otherwise the update will not activate. The updated version that includes the security fixes in the desktop client is 101.0.4951.64.

Users of other Chromium-powered web browsers such as Brave and Edge should also be alert to the fact that security updates are likely to follow in the coming days. I’ll update this article as soon as I can confirm those updates have been rolled out, with instructions on what to do. Of course, Chrome for Android users should also make sure that the app is updated as below.

Windows, Linux and Mac users of the Google Chrome browser can rest easy for now. This latest security warning is aimed solely at smartphone users for a change. In a Chrome update confirmation published on May 9, Google has unveiled a whopping 13 security solutions. Of these, eight have been assigned Common vulnerabilities and exposures (CVE) severity ratings of high, with one given an average score. The rest, four in all, are packed with “various fixes” from ongoing internal security work that have not been assigned CVE numbers.
