Google Chrome Zero-day Vulnerability Exploited in the Wild (CVE-2023-7024)

Qualys Security Advisory

Google has released patches to address a high-severity vulnerability in the Chrome browser. Tracked as CVE-2023-7024, the vulnerability is being exploited in the wild.

CVE-2023-7024 is a heap-based buffer overflow vulnerability in the open-source WebRTC framework. Many other web browsers, such as Mozilla Firefox, Safari, and Microsoft Edge, also use the WebRTC framework to provide Real-Time Communications (RTC) capabilities (e.g., video streaming, file sharing, and VoIP telephony) via JavaScript APIs. The vast use of the WebRTC framework makes this vulnerability more severe.

Clément Lecigne and Vlad Stolyarov of Google’s Threat Analysis Group (TAG) have discovered the high-severity vulnerability in Google Chrome.

CVE-2023-7024 is the eighth zero-day vulnerability fixed by Google this year. The following are the other seven zero-days:
