Google Chrome Browser Zero-Day Vulnerability Exploited in Wild

Google Chrome released the first security update in 2024 with a fix for the zero-day bug actively exploited in Wild.

An update to Google Chrome 120.0.6099.234 for Mac, 120.0.6099.224 for Linux, and 120.0.6099.224/225 for Windows will be released in the next days or weeks.

Hackers exploit zero-day flaws as these vulnerabilities are unknown to software vendors, making them valuable for launching attacks before security patches are developed.

Even exploiting zero-day flaws can provide a strategic advantage to the threat actors in launching targeted and undetected attacks.

Recently, the following cybersecurity researchers identified multiple vulnerabilities, along with a zero-day flaw exploited in the wild:

CVE-2024-0517 Reported by Toan (suto) Pham of Qrious Secure on 2024-01-06

CVE-2024-0518 Reported by Ganjiang Zhou (@refrain_areu) of ChaMd5-H1 team on 2023-12-03

CVE-2024-0519 Reported by Anonymous on 2024-01-11

The zero-day exploit (CVE-2024-0519) hits the V8 JavaScript engine with out-of-bounds memory access. However, Google didn’t provide details regarding the attack scope or telemetry. 

At the moment, Google has confirmed that the vulnerability is actively exploited in the wild., which was reported anonymously.
