Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 93.0.4577.82

Description The issue is related to a use after free in the Permissions 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, allowing the attacker to cause a denial of service or execute arbitrary code.

Recommendations For versions prior to 93.0.4577.82, update to version 93.0.4577.82 or later to resolve the issue. As a temporary workaround, consider restricting access to potentially vulnerable HTML pages until the update is applied.
