Google is adjusting its Chrome browser update schedule to include security fixes twice a week. The company’s security team uses artificial intelligence tools for vulnerability discovery, triage, and patch development.
The 1,072 security bugs fixed in Chrome’s two releases in June exceeded the total number of flaws addressed in the previous 23 releases over two years, which stood at 1,036. This spike in identified vulnerabilities has driven the shift toward more frequent updates.
AI changes the economics of cybersecurity
Chrome’s director of engineering Doug Turner stated that large language models have fundamentally shifted the economics of cybersecurity. He described vulnerability discovery as an automated, industrial-scale operation.
Turner explained that the high volume of vulnerability fixes made it necessary to provide two updates per week during this period. He noted that applying models like Gemini allows the team to preemptively fix vulnerabilities and outpace adversaries.
A new equilibrium expected
Parisa Tabriz, Chrome vice president and general manager, described the current year as an inflection point for both offense and defense in cybersecurity. She acknowledged the near-term spike in bugs but predicted a new equilibrium will eventually emerge.
Google trains its AI model on every past Common Vulnerabilities and Exposures (CVE) entry and every line of code in Chromium's history. The company has been using machine learning for vulnerability discovery and fuzz testing since at least 2012.
In addition to AI-driven patching, the Chrome security team is rewriting parts of its C++ code in Rust to improve memory safety. The browser is currently piloting security fixes twice a week, moving toward a major release every two weeks with additional weekly security updates.
Chrome’s version numbers jumped from 126 in June 2024 to 149 and 150 in June 2025. Other major technology firms are also addressing significant numbers of security flaws, with Microsoft patching 570 vulnerabilities across its product lines in one month and Apple reportedly patching 482 bugs.
