Overview

CISA has recently added a type of confusion vulnerability to its Known Exploited Vulnerabilities (KEV) catalog. This flaw affects the popular Google Chrome browser and potentially other Chromium-based browsers. It poses a serious risk and has been rated as high due to its potential for exploitation.

Type confusion vulnerabilities, like the one found in Google Chrome’s V8 engine, can allow remote attackers to cause heap corruption through specially crafted HTML pages. This issue isn’t limited to Google Chrome; it could also impact other Chromium-based browsers, such as Microsoft Edge, Opera, and more.

Google is aware that this vulnerability is being actively exploited in the wild. In response, they have recently addressed a critical zero-day vulnerability, CVE-2024-7965, which affects versions of Chrome earlier than 128.0.6613.84.
