Google’s artificial intelligence discovered and fixed a security bug that had been hiding in Chrome for 13 years, a flaw unnoticed since around 2011. According to a report from XDA Developers, Google’s AI systems are now identifying and patching more vulnerabilities in Chrome than any human security team could manage alone. The process combines Google’s existing fuzzing tool, ClusterFuzz, with AI that learns from past bugs and understands code context to pinpoint likely vulnerabilities. The bug had lingered in a browser used by approximately 3.45 billion people globally and was not exploited during that time. The XDA report indicates AI-assisted fixes are happening faster due to a compounding effect: as AI models process more code and bug reports, they improve, and finding more bugs creates more training data, leading to better detection. Google is also broadening the range of what its AI tools analyze, and the models are advancing in reasoning about code logic. Security researchers refer to this positive feedback loop as a force multiplier. For most Chrome users, no action is required, as Google automatically patches Chrome in the background, and AI-found bugs are fixed through the same update process.
