**1.0 Introduction**
Chrome is now used by over three billion users worldwide, but every single one of them needs to update their browser urgently. Google’s Threat Analysis Group discovered vulnerability, CVE-2023-2033, stems from a “Type Confusion in V8”. Type confusion in V8 in Google Chrome prior to 112.0.5615.121 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. This occurs when a program uses one method to allocate or initialize a resource but an incompatible method then access that resource, potentially providing unsecured access to the browser’s memory.
**2.0 Impact**
Allow attackers to trigger browser crashes after successful exploitation by reading or writing memory out of buffer bounds, threat actors can also exploit them for arbitrary code execution on compromised devices.
**3.0 Affected System and Devices**
