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

Description The issue is related to the use of memory after it has been freed, which can be exploited by a remote attacker to potentially execute code in the context of a privileged process. This can be achieved through a specially crafted HTML page. The exploitation may lead to heap corruption.

Recommendations For versions prior to 94.0.4606.54, update to version 94.0.4606.54 or later to resolve the issue. As a temporary workaround, consider restricting access to offline mode in Google Chrome on Android until the update is applied.
