Google has fixed an actively exploited zero-day vulnerability in the Chrome 89.0.4389.72 version released today, March 2nd, 2021, to the Stable desktop channel for Windows, Mac, and Linux users.
"Google is aware of reports that an exploit for CVE-2021-21166 exists in the wild," the Google Chrome 89.0.4389.72 announcement reads.
The Google Chrome web browser will then automatically check for the new update and install it when available.
"Access to bug details and links may be kept restricted until a majority of users are updated with a fix," Google added.
Google fixed another Chrome zero-day actively exploited in the wild in February, a heap buffer overflow bug in V8 tracked as CVE-2021-2114 and rated as high severity.
Last year, Google fixed five more actively exploited Chrome zero-days within a single month, between October 20 and November 12.
