The vendor has published an official fix in Chrome version 153.0.8010.36.
Potential Impact
Successful exploitation could allow remote attackers to execute arbitrary code within the sandboxed environment of the Chrome browser, potentially compromising the confidentiality, integrity, and availability of the affected system.
