Google has released Chrome 91.0.4472.164 for Windows, Mac, and Linux to fix seven security vulnerabilities, one of them a high severity zero-day vulnerability exploited in the wild.
The new Chrome release has started rolling out worldwide to the Stable desktop channel and will become available to all users over the following days.
Google Chrome will automatically update itself on the next launch, but you can also manually update it by checking for the newly released version from Settings > Help > 'About Google Chrome.'
Even though type confusion weaknesses would generally lead to browser crashes following successful exploitation by reading or writing memory out of the bounds of the buffer, they can also be exploited by threat actors to execute arbitrary code on devices running vulnerable software.
While Google said that it is aware of CVE-2021-30563 in the wild exploitation, it did not share info regarding these attacks to allow the security update to deploy on as many systems as possible before more threat actors start actively abusing.
