Google Secures Critical V8 Vulnerability in Chrome

By Netvora Tech News

Google has recently patched a critical security vulnerability in Chrome, which was actively exploited by attackers. The vulnerability, identified as CVE-2025-5419, resides in V8, the JavaScript engine used by Chrome and other browsers to execute JavaScript code.

V8: A Prime Target for Attackers

V8 is a frequent target for attackers who exploit vulnerabilities without a patch available at the time of the attack. The impact of this vulnerability was assessed as high by Google, making it a serious concern for users.

The vulnerability allows an attacker to execute code within the context of the browser, enabling them to potentially read or modify data from other websites and steal sensitive user information. Additionally, it allows attackers to escape the Chrome sandbox, giving them access to more sensitive areas of the system.

Reported and Patched

The vulnerability was reported to the Chrome team by two researchers from the Google Threat Analysis Group on May 27. The group specializes in combating government-sponsored and executed attacks against Google and its users.

Google claims that the issue has been resolved through a configuration adjustment, which was rolled out to users on May 28. Further information about the vulnerability, the observed exploitation, and the implemented fix has not been disclosed.

Security Implications

Vulnerabilities with a rating of "high" are not, on their own, sufficient to take over a system. A second vulnerability, such as one in the underlying operating system, would be required to achieve this.
