### AI overview

Praetorian describes using Claude Code and a large language model to investigate the FreeBSD kernel for vulnerabilities. The excerpt says the work identified multiple bugs, including CVE-2026-3038, a stack overflow fixed in FreeBSD-SA-26:05.route, and outlines a two-part series covering discovery and exploitation methodology.

### Source excerpt

Overview Earlier this year, a team at Praetorian was building Constantine, our automated 0-day discovery engine. I wanted to find techniques worth folding into it, so on the side I started poking at the FreeBSD kernel with Claude Code, running on Opus 4.6, which was the latest Opus model at the time. A few days [...] The post FreeBSoD: Leveraging Language Models to Find and Exploit Kernel Bugs (Part 1 of 2) appeared first on Praetorian.
