Greg Kroah-Hartman has spent decades tending the stable Linux kernel branch. He has reviewed every security flaw reported since 2005. Yet even he sounded alarmed at Rust Week in Utrecht this month. Speaking to the crowd, he declared that Rust developers would save Linux. The reason? A torrent of new vulnerabilities uncovered by artificial intelligence tools. The numbers tell a stark story. The kernel team now fields roughly 13 CVEs daily. Recent examples include Dirty Frag, Copy Fail, and Fragnesia. Each arrived courtesy of AI-assisted scanning that spots subtle flaws in C code far faster than humans ever could. Kroah-Hartman, who addressed the conference on untrusted data, put it plainly. “I’m here to talk about untrusted data and Linux, and how Rust is going to save us.” He followed with a bolder claim. “You are going to save Linux. Sorry, it’s all on you.” Such language surprises no one familiar with his style. Yet the underlying pressure is real. Linux powers the cloud. It underpins AI training clusters.…
