Emergency Update Addresses High-Severity Flaw

Google has released an emergency security update for the Chrome web browser across Windows, Mac, and Linux platforms. The update addresses a high-severity vulnerability that is being actively exploited in the wild. This marks the seventh zero-day vulnerability that Google has patched for its browser in 2025. The company confirmed its awareness that an exploit for the flaw exists.

As is standard procedure to allow a majority of users to apply the update, Google has not released the full technical details of the vulnerability or the threat actors exploiting it. The company’s advisory credits the discovery and reporting of the security flaw to an anonymous security researcher.

Users Urged to Update Chrome Immediately

The new patch is being rolled out globally to the Stable channel. Google has updated the Chrome browser to version 139.0.7114.65 for Windows, macOS, and Linux. The company stated that the update would be available to all users over the coming days and weeks. Chrome users can manually check for the new version and install it by navigating to Settings > Help > About Google Chrome. The browser will automatically scan for the latest update and prompt for a relaunch to complete the installation.

Given the active exploitation of this zero-day, applying the security patch is the most critical step for users to protect themselves from potential attacks leveraging this vulnerability. The consistent discovery and patching of zero-day flaws highlight the persistent efforts by attackers to find and exploit browser vulnerabilities.
