Recently, Google has released an out-of-band security update to fix a new actively exploited zero-day flaw in its Chrome web browser.

The high-severity flaw, tracked as CVE-2022-4262, concerns a type confusion bug in the V8 JavaScript engine. Clement Lecigne of Google’s Threat Analysis Group (TAG) has been credited with reporting the issue on November 29, 2022.

Type confusion vulnerabilities could be weaponized by threat actors to perform out-of-bounds memory access or lead to a crash and arbitrary code execution.

According to the NIST’s National Vulnerability Database, the flaw permits a “remote attacker to potentially exploit heap corruption via a crafted HTML page.”
