Google has issued its second emergency Chrome update in a week to fix a serious security flaw threatening over 3.5 billion users across Windows, Mac, Linux, and Android. The vulnerability, tracked as CVE-2025-12036, affects Chrome’s V8 JavaScript engine and could allow hackers to execute malicious code remotely by luring users to infected websites.
The flaw was discovered by Google’s AI-powered Big Sleep security system, but technical details remain confidential until most users receive the patch. The update is being rolled out globally over the next few days.
To stay protected, users should update Chrome to version 141.0.7390.122 or .123 on Windows and Mac, 141.0.7390.122 on Linux, and 141.0.7390.122 on Android. Chrome updates automatically, but users can also check manually under Settings → About Google Chrome, which triggers an update if available.
Google warns that without restarting the browser after the update, the patch won’t apply. With reports of active exploitation, users are urged to update immediately to secure their data and devices.
