Critical Google Chrome Security Update Confirmed—Don’t Risk Waiting When You Can Act Now

Although it has only been a week since I last wrote about a Chrome security update, things are a lot more critical this time around. Literally. Whereas the April 22 update concerned a mere three vulnerabilities, two of which climbed to high on the severity scale, the latest security alert concerns a whopping 30 security flaws, the vast majority high-rated, with four reaching critical Common Vulnerability Scoring System severity status.

The four critical security vulnerabilities are listed by Google in an April 28 Chrome update alert as follows:

CVE-2026-7363: Use after free in Canvas.
CVE-2026-7361: Use after free in iOS.
CVE-2026-7344: Use after free in Accessibility.
CVE-2026-7343: Use after free in Views.

Although Google does not release technical details of such bugs “until a majority of users are updated with a fix,” according to Chrome technical program manager, Srinivas Sista, that these Common Vulnerabilities and Exposures get the maximum severity rating is enough to know that you need to take them very seriously indeed. Not that the fact that there are 23 high-rated vulnerabilities should be ignored when coming to your update urgency calculations, of course.

Yes, Google Chrome does have automatic updates. No, that doesn’t mean your application has already been updated, nor that it will be today or tomorrow. The latest browser security update “will roll out over the coming days/weeks,” Sista confirmed. Which means that, out of an abundance of caution, I would recommend that you update now. This is easy enough to do: go to Help|About Google Chrome and the update will begin. Ensure you follow the instructions to relaunch the browser at the end of this process, or the security update will not activate.
