Chrome users need to update their browsers immediately as Google addresses a critical vulnerability that hackers are actively exploiting. Additional security measures are recommended.

This latest incident marks the fourth actively exploited zero-day vulnerability fixed in Chrome this year. It follows three other security flaws: CVE-2025-2783 disclosed in March, CVE-2025-4664 patched in May, and CVE-2025-5419 addressed in June. Each of these vulnerabilities were considered critical and patched through emergency updates.

Based on a Chromium commit, Google's web browser is peeking at whether your PC is eligible for Windows 11, and this functionality is supposedly live now.

These results will likely help determine how many users are still running Chrome on devices that can’t be upgraded to Windows 11, which will influence how long Chrome continues to be supported on Windows 10. This data could affect when future updates roll out and how long users on older systems get full browser support and security patches.
