External security researchers identified and reported these vulnerabilities, which have been instrumental in ensuring the safety and security of Chrome users.

1. CVE-2024-9602: A type confusion vulnerability in V8, reported by Seunghyun Lee (@0x10n), was awarded $55,000 for the discovery.
2. CVE-2024-9603: This update also addresses another confusion issue in V8, reported by @WeShotTheMoon and Nguyen Hoang Thach of Star Labs.

Google has expressed gratitude to all security researchers who contributed to identifying these vulnerabilities during the development cycle, helping prevent them from reaching the stable channel.

Internal Security Measures

In addition to the contributions from external researchers, Google’s internal security team has been actively working on identifying and fixing various security issues. The update includes fixes from internal audits, fuzzing, and other initiatives.

Google’s ongoing internal security efforts utilize tools like AddressSanitizer, MemorySanitizer, UndefinedBehaviorSanitizer, Control Flow Integrity, libFuzzer, and AFL to detect potential vulnerabilities.

Users are encouraged to update their browsers promptly to benefit from these security enhancements. Google restricts bug details until most users have received the fixes to ensure widespread protection.
