CVE-2022-4262

Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 108.0.5359.94

Description The issue is related to a type confusion vulnerability in the V8 JavaScript engine of Google Chrome, allowing a remote attacker to potentially exploit heap corruption via a crafted HTML page. This vulnerability has been exploited in the wild, and its severity is considered high. The vulnerability exists in how V8 handles the parsing of class static blocks within arrow function heads, particularly with the 'this' keyword. It leverages bytecode flushing for exploitation and is a non-trivial feedback slot type confusion in V8.

Recommendations For Google Chrome versions prior to 108.0.5359.94, update to version 108.0.5359.94 or later to resolve the issue. As a temporary workaround, consider restricting access to potentially vulnerable HTML pages until the update is applied.
