Chrome and Edge were both hit by a V8 confusion vulnerability

Chrome and Edge were both hit by a V8 confusion vulnerability

Due to discovering a vulnerability with an exploit in the wild, Google is encouraging users on Windows, macOS, and Linux to upgrade their Chrome builds to version 99.0.4844.84.

Because of the vulnerability and its potential complications, Google is keeping quiet about specifics. “CVE-2022-1096: Type Confusion in V8. Reported by anonymous on 2022-03-23” was the extent of Google’s explanation of the problem.

V8 is Chrome’s JavaScript engine; it’s also used server-side in Node.js, but the company hasn’t specified whether it’s affected. Google also stated that details about the flaw would be kept under wraps until most users had upgraded their browsers.

More Chrome zero-day issues in the wild

Google said it will keep restrictions in place if the flaw is in a third-party library that other projects rely on but haven’t repaired yet. A day later, Microsoft made its own statement, claiming that the problem had been resolved in Edge version 99.0.1150.55, released the same day.

At the beginning of the month, Google said that it was seeing additional Chrome zero-day problems in the wild. Meanwhile,  Google Chrome claimed it was faster than Apple Safari on Mac earlier this month.

Chrome for Mac is faster than Safari

Google employed Speedometer 2.0, an Apple-developed benchmark that analyzes the responsiveness of JavaScript-based Web apps, to test Chrome. The higher the score, the better the browser’s performance with JavaScript.

Google discovered that Chrome 99 for Mac received a Speedometer score of 300, making it the highest-scoring browser on macOS, surpassing the WebKit-based Safari and other Chromium-based browsers such as Brave, Microsoft Edge, and Vivaldi.

Chrome’s quicker performances are credited to Google’s ThinLTO build optimization approach in Chrome 99, which has made it 7% faster than current Safari builds. Because of new graphics enhancements, Chrome was 15 % faster than Safari in graphics performance.

Tip: Google sees increase of zero-day vulnerabilities in internet browsers.
