Claude Mythos 5.5 Reportedly Roots a Linux Kernel in 53 Minutes

One number from the Claude 5.5 leak made me stop scrolling: Mythos 5.5, a cybersecurity-only edition, is claimed to exploit the Linux kernel and gain root on its own in 53 minutes.

If true, this is no longer ordinary coding benchmarks. This is a model built for offensive work, with access limited to top-tier security institutions.

But precisely because the number is that dramatic, I file it as a leak claim. Even official release numbers need testing, let alone figures pulled from a snippet of source code.
