Platform takeover via SmmRuntime access-control failure
Published May 12, 2023 · Updated Jan 24, 2025
Improper access control in S2600WTT BIOS 0016 allows local administrators to gain System Management Mode access and control the platform. Intel identifies SmmRuntime as the vulnerable function but does not disclose which access-control operation accepts malicious code. Exploitation requires local administrative access and user interaction; successful exploitation gives full control of the platform.
