Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 90.0.4430.212

Description The issue is related to a use after free in the File API, which could allow a remote attacker to exploit heap corruption via a crafted HTML page. This may lead to unauthorized access to confidential data, disruption of data integrity, and potentially cause a denial of service.

Recommendations For versions prior to 90.0.4430.212, update to version 90.0.4430.212 or later to resolve the issue. As a temporary workaround, consider restricting access to crafted HTML pages that could exploit the use after free in the File API until a patch is applied.
