Chrome Security Update Addressing 21 Vulnerabilities

The Chrome team has released Chrome 141.0.7390.54/55 to the stable channel for Windows, Mac, and Linux, rolling out over the coming days and weeks.

This update delivers critical security fixes, including 21 distinct vulnerabilities that span high, medium, and low severity.

External researchers contributed to several of these fixes, earning rewards up to $25,000. Users are strongly encouraged to update immediately to benefit from these protections and ensure the safest possible browsing experience.

Overview Vulnerabilities

Chrome 141 introduces fixes for two high-severity heap buffer overflows and multiple medium-severity issues involving side-channel leaks, out-of-bounds reads, and improper implementations across various components, including WebGPU, Video, Storage, Omnibox, Media, Tab, and V8.

Low-severity bugs in Storage and V8 have also been addressed. Most external contributions were discovered through advanced techniques like fuzzing, AddressSanitizer, MemorySanitizer, UndefinedBehaviorSanitizer, Control Flow Integrity, libFuzzer, and AFL.

Below is a summary of the externally reported vulnerabilities, their severity, and the reward amounts:
