Google has released security update for the Chrome browser, bringing it to version 129.0.6668.100/.101 for Windows and Mac, and 129.0.6668.100 for Linux.

This update addresses three security vulnerabilities, with two high-severity type confusion flaws in the V8 JavaScript engine being the most critical. These flaws could potentially allow attackers to execute arbitrary code on affected systems​.

Vulnerability Details

  • CVE-2024-9602 (CVSS score 8.8) - type confusion within V8. This type of vulnerability occurs when a resource is accessed using an incompatible type, leading to memory corruption and possible code execution​
  • CVE-2024-9603 (CVSS score 8.8) - type confusion in V8

These type confusion issues are rated as high severity because they can compromise system integrity, enabling attackers to run code remotely. As a precaution, Google has restricted access to technical details until a majority of users have updated, to prevent potential exploitation​.

Users are advised to update to the latest version immediately by navigating to Help > About Google Chrome in their browser settings​.

The update also includes various fixes identified through internal audits, fuzzing, and other techniques, such as AddressSanitizer and MemorySanitizer.
