Google pilots twice-weekly Chrome updates after bug surge

Google has accelerated its Chrome browser security updates to twice a week in a pilot program, a direct response to an unprecedented surge in vulnerability discoveries driven by artificial intelligence. The company announced the change alongside the release of Chrome version 151 on July 29, which patches 370 security flaws, including seven rated as critical. This follows the two major releases in June, Chrome 149 and 150, which together resolved 1,072 security issues, a total exceeding the number of bugs patched across the prior 23 stable Chrome releases combined.

Officials attribute the dramatic increase in findings to the integration of advanced AI tools, particularly large language models, into their internal security workflows. These systems now automate the processes of discovering vulnerabilities, triaging bug reports, determining severity, generating candidate patches, and creating test suites. One notable discovery by an AI agent harness leveraging Google's Gemini models was a critical sandbox escape vulnerability that had remained undetected in the Chrome codebase for over 13 years. This flaw, patched earlier this year, could have allowed a compromised process to trick...
