Google Patches Third Actively Exploited Chrome Zero-Day of 2022

A Chrome 100 update that Google announced on Thursday resolves two vulnerabilities in the popular browser, including one already exploited in the wild.

Tracked as CVE-2022-1364 and considered “high severity,” the exploited security hole is described as a type confusion in the V8 JavaScript and WebAssembly engine.

Attacks targeting type confusion bugs in Chrome’s V8 engine may lead to arbitrary code execution. All Chromium-based browsers are impacted.

“Google is aware that an exploit for CVE-2022-1364 exists in the wild,” the internet giant warns.

The security defect was identified and reported by Clément Lecigne of Google’s Threat Analysis Group on Wednesday. As per Google’s policies, no bug bounty reward will be issued for this flaw.

The latest Chrome iteration is now rolling out to Windows, Mac, and Linux users as version 100.0.4896.127.

This is the fourth Chrome update that Google releases within a three-week time span. The first was an emergency update issued on March 25 to address a zero-day vulnerability.

Google resolved three Chrome zero-day flaws so far in 2022, including one that has been exploited by at least two North Korean state-sponsored hacking groups in attacks on hundreds of entities worldwide.

Last year, there were 14 reported Chrome zero-days exploited in the wild, showing that threat actors are increasingly interested in Google’s browser compared to Firefox, Safari and Internet Explorer.
