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

Description The issue is related to type confusion in the V8 JavaScript engine, which can be exploited by a remote attacker to potentially access confidential data, compromise data integrity, and cause a denial of service using a specially crafted HTML page.
