Chrome 149 ships with a record 429 security fixes

Google has rolled out Chrome 149, a release notable for bundling patches for 429 separate security issues — the largest number of fixes ever included in a single Chrome update, according to researchers tracking the browser's changelog. The scale of the update reflects both the growing complexity of modern browsers and increased scrutiny from bug-bounty researchers and automated testing tools. Separately, researchers reported that an autonomous AI agent built by a security startup uncovered 21 previously unknown vulnerabilities in the open-source FFmpeg multimedia framework within days — a result that has stirred fresh debate over how AI tools are reshaping vulnerability research for defenders and attackers alike.
