Code-execution flaw in UEFI firmware threatens most servers on planet Earth
A memory-corruption vulnerability tracked as CVE-2026-97631 affects TianoCore EDK II, the open source UEFI firmware codebase used by most server vendors and cloud providers to build boot-time firmware. With a CVSS score of 9.5, the flaw in an ICMP component allows remote code execution before operating system defenses like Secure Boot activate. Attackers can exploit this to run malicious payloads during boot and potentially install persistent code that executes on each system startup.
Why it matters: Server administrators and cloud providers using UEFI firmware from AMI, Insyde, Phoenix, Microsoft Project Mu, and other EDK2-based implementations face immediate risk of pre-boot compromise that bypasses firmware attestation and Secure Boot protections, requiring urgent firmware patching across global data center infrastructure.
