Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 94.0.4606.54

Description The issue is related to a use after free in the File System API, which could allow a remote attacker to potentially exploit heap corruption via a crafted HTML page. This could impact the confidentiality, integrity, and availability of protected information.

Recommendations For Google Chrome versions prior to 94.0.4606.54, update to version 94.0.4606.54 or later to resolve the issue.
