Google on Tuesday released a new version of Chrome web-browsing software for Windows, Mac, and Linux with fixes for two security vulnerabilities, both of which it says are under active exploitation.
While Google moved to fix the flaw quickly, security researcher Rajvardhan Agarwal published a working exploit over the weekend by reverse-engineering the patch that the Chromium team pushed to the open-source component, a factor that may have played a crucial role in the release.
Also resolved by the company is a use-after-free vulnerability in its Blink browser engine (CVE-2021-21206). An anonymous researcher has been credited with reporting the flaw on April 7.
“Google is aware of reports that exploits for CVE-2021-21206 and CVE-2021-21220 exist in the wild,” Chrome Technical Program Manager Prudhvikumar Bommana noted in a blog post.
Chrome 89.0.4389.128 is expected to roll out in the coming days. Users can update to the latest version by heading to Settings > Help > About Google Chrome to mitigate the risk associated with the flaws.
