rv_inc proves 89 theorems in Lean 4 on Linux, uncovering a silent kernel bug

rvinc published a technical breakdown of formally verifying Linux kernel isolation: they proved 89 theorems in Lean 4, the spec exposed a silent kernel bug (fixed via a kernel patch), and they crashed the Aeneas verification tool along the way. Grigore Rosu notes formal verification of Linux always surfaces something interesting — bugs in both the kernel and the tools — and invites others to join the effort.
