TianoCore Bug Threatens Global Server Boot Chain

A critical memory‑corruption bug (CVE-2026-97631) in the TianoCore EDK II UEFI reference code can execute attacker code during server boot, before OS-level protections like Secure Boot and TPM take effect. Because EDK II is widely reused by BIOS vendors and cloud forks, a single flaw and the public release of patch code make rapid, large‑scale exploitation plausible while remediation is slow and operationally difficult. — This raises urgent questions about firmware supply‑chain governance, coordinated disclosure practices, cloud trust, and public policy for patching and liability across hardware vendors and data centers.
