Highlighted Security Fixes

The latest update includes six critical security fixes, with contributions from external researchers. Notable among these are:

• CVE-2024-6100: Type Confusion in V8 – Reported by Seunghyun Lee (@0x10n) during SSD Secure Disclosure’s TyphoonPWN 2024 on June 4, 2024. This high-severity vulnerability earned a reward of $20,000.

• CVE-2024-6103: Use After Free in Dawn – Also reported by wgslfuzz on June 4, 2024, the reward remains to be determined.

Google has restricted access to bug details and links until most users have updated their browsers. This precaution ensures that vulnerabilities are not exploited before users are protected.

Ongoing Security Efforts

In addition to the contributions from external researchers, Google’s internal security team has been actively working to identify and fix vulnerabilities.

This includes various fixes from internal audits, fuzzing, and other initiatives. Tools like AddressSanitizer, MemorySanitizer, UndefinedBehaviorSanitizer, Control Flow Integrity, libFuzzer, and AFL are crucial in detecting security bugs.

Google extends its gratitude to all security researchers who collaborated during the development cycle to prevent security bugs from reaching the stable channel.
