Some of the vulnerabilities are rated High. Google writes that an exploit for CVE-2021-21166 exists in the wild.  Further problems were found and fixed internally through audits and fuzzing. So, the browser should be updated quickly. The Chrome build for Windows, Mac and Linux will be rolled out to systems via the automatic update feature in the next few days. However, you can also download this build here.

Addensum: Google's develpers announced in the Chromium blog, that they intend to relase each 4 weeks a new version.
