OpenAI says GPT-6 Cyber found 81 previously unknown Firefox flaws | ETIH EdTech News

OpenAI is giving approved security teams access to GPT-6 Cyber, an AI model designed to find software vulnerabilities and demonstrate whether they can actually be exploited.

The company says researchers used the model to uncover 81 previously unknown Firefox vulnerabilities classified by Mozilla as high severity. Mozilla has released fixes for many of them, following earlier rounds of testing with other advanced AI models.

Brian Grinstead, Distinguished Engineer at Firefox, says: “Even after further hardening with multiple generations of frontier models, GPT‑6 Cyber uncovered previously unknown high-severity vulnerabilities, identified architectural improvements, and helped us ship fixes to millions of users.”

The findings accompany a restricted rollout through Daybreak Red, OpenAI’s access program for more advanced exploit development and authorized security testing.

Finding flaws and demonstrating their impact

OpenAI says its researchers also used GPT-6 Cyber to develop working exploits for 948 Linux kernel vulnerabilities, producing code that demonstrates how the flaws can be used.

Following Linux community guidance, the company disclosed 304 critical findings to maintainers with proposed fixes. Work to address other vulnerabilities is continuing.
