Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 91.0.4472.101

Description The issue is related to a use after free in the Extensions component of Google Chrome, which could allow a remote attacker who has compromised the renderer process to potentially exploit heap corruption via a crafted HTML page. This could lead to unauthorized access to confidential data, disruption of data integrity, and denial of service.

Recommendations For Google Chrome versions prior to 91.0.4472.101, update to version 91.0.4472.101 or later to resolve the issue. As a temporary workaround, consider restricting access to the Extensions component until a patch is applied.
