A painful processToday, kernel maintainers who want a kernel.org account must find someone already in the PGP web of trust, meet them face‑to‑face, show government ID, and get their key signed. The process is like a manual, global scavenger hunt. Linux kernel maintainer Greg Kroah-Hartman, speaking at the Linux Foundation Members Summit, described it as a "pain to do and manage." That's because it's tracked by manual scripts, the keys drift out of date, and the public "who lives where" map creates privacy and social‑engineering risk.
The guest runs in a separate virtual address space enforced by the CPU hardware. A bug in the guest kernel cannot access host memory because the hardware prevents it. The host kernel only sees the user-space process. The attack surface is the hypervisor and the Virtual Machine Monitor, both of which are orders of magnitude smaller than the full kernel surface that containers share.
