Google: Big Sleep AI Agent Puts SQLite Software Bug to Bed

Google's Big Sleep, an AI agent developed by Project Zero and DeepMind, discovered a stack buffer underflow in a public SQLite build; the bug was reported to SQLite developers and fixed the same day before it reached an official release. The report frames this as a milestone for AI-based vulnerability discovery, references prior LLM-based findings (Team Atlanta/Atlantis) and AI-augmented fuzzing/static analysis tools, and argues that AI could give defenders an edge by finding variants and hard-to-detect bugs earlier in development.
