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 Autofill component, which can be exploited by a remote attacker who has compromised the renderer process. This can potentially lead to heap corruption via a crafted HTML page. The exploitation of this issue may allow an attacker to access confidential data, compromise data integrity, and 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 untrusted HTML pages to minimize the risk of exploitation.
