Lean이 프로그램의 정확성을 증명했지만, 그 안에서 버그가 발견됨

The discovery of a heap buffer overflow in the Lean 4 runtime, despite formal verification of the application logic, highlights the critical dependency on the Trusted Computing Base (TCB). It serves as a stark reminder that formal proofs are only as secure as the unverified runtime layers they execute upon, necessitating rigorous security testing like AI-augmented fuzzing even for 'proven' systems.
