Google Addresses Critical Zero-Day Vulnerability in Chrome Exploited by Cyber Attacks
Google has issued an urgent security patch addressing the third Chrome zero-day vulnerability that has been under active exploitation since early 2025.
The company acknowledges the existence of an exploit for CVE-2025-5419 in the wild, as detailed in a security advisory released recently.
This vulnerability, classified as high-severity, is attributed to an out-of-bounds read and write issue within Chrome’s V8 JavaScript engine. It was reported just a week prior by members of Google’s Threat Analysis Group.
Shortly after the vulnerability was identified, Google implemented a configuration adjustment to mitigate the risk across all platforms in the Stable channel.
The release of versions 137.0.7151.68/.69 for Windows and macOS, and 137.0.7151.68 for Linux, provides the necessary fix. These updates are being deployed to users in the Stable Desktop channel over the coming weeks.
Users are advised that while Chrome generally updates automatically, the update process can be expedited by navigating to the Chrome menu > Help > About Google Chrome, completing the update, and clicking the ‘Relaunch’ button.
