OpenAI's autonomous AI pipeline discovered, validated, exploited, and patched 948 distinct Linux kernel local privilege escalation (LPE) vulnerabilities during an October 2026 experiment. The system analyzed 2,308 candidates, dynamically reproduced 1,724 flaws, and produced working root exploits using GPT-6 Cyber and GPT-5.5 Cyber models at a cost of $1.21 million. Human researchers reviewed root-cause analysis and patches before disclosure to Linux kernel maintainers. The research demonstrates a 16x to 55x cost advantage over traditional bounty programs while introducing at least 10 novel exploitation techniques.
