Google Patches Eighth Chrome Zero-Day Vulnerability in 2026

Google has recently patched a significant security issue in Chrome. This is important news as of November 10, 2026, because it highlights ongoing security challenges in web browsers that affect users worldwide.

What Happened?

On November 10, 2026, Google announced an emergency update to fix a zero-day vulnerability in the Chrome web browser. This vulnerability, identified as CVE-2026-125350, is classified as high severity and is actively being exploited in attacks.

Understanding the Vulnerability

The flaw is a type of security issue known as a Use-After-Free (UAF) vulnerability. This occurs when the browser's XML parser processes data, deletes an object from memory, but does not clear the pointer that references that object. If an attacker exploits this, they can manipulate memory and potentially execute malicious code.

Affected Systems

The security update is available for users on multiple platforms, including:

• Windows
• macOS (versions 157.0.8103.50 and 157.0.8103.51)
• Linux (version 157.0.8103.50)

Google has rolled out the patch immediately, but it may take some time for all users to receive it.
