Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 93.0.4577.63

Description The issue is related to a use after free in the Web Share feature of Google Chrome, which can be exploited by a remote attacker to potentially impact confidentiality, integrity, and availability. This can be achieved via a crafted HTML page, allowing for heap corruption.

Recommendations For versions prior to 93.0.4577.63, update to version 93.0.4577.63 or later to resolve the issue. As a temporary workaround, consider disabling the Web Share feature until a patch is available. Restrict access to untrusted HTML pages to minimize the risk of exploitation.
