19 Nov
Summary
- A high-severity, zero-day vulnerability was actively exploited in Chrome.
- The flaw involved a type confusion issue in the V8 JavaScript engine.
- Google issued an emergency patch for desktop Chrome versions.
Google has swiftly addressed a severe security threat by deploying an emergency patch for its desktop Chrome browser. The vulnerability, officially cataloged as CVE-2025-13223, is a zero-day exploit, meaning it has already been used in the wild. This discovery highlights the ongoing risks associated with sophisticated cyberattacks.
The core of the vulnerability lies in a 'type confusion' flaw within Chrome's V8 JavaScript engine. This programming error can be manipulated by attackers to corrupt the browser's memory, potentially leading to the execution of malicious code on a user's system. Reports suggest this exploit could be delivered via crafted HTML pages, possibly through malicious websites or phishing attempts.
The patch is being rolled out automatically to Chrome users on Windows, Mac, and Linux. Google recommends relaunching the browser to ensure the update is fully applied. Microsoft has also released a corresponding fix for its Edge browser, which is based on the same Chromium engine, underscoring the widespread impact of this security issue.
