FKIE_CVE-2026-0438
Vulnerability from fkie_nvd - Published: 2026-05-15 02:16 - Updated: 2026-06-17 10:10
Severity
Summary
A System Management Mode (SMM) handler could perform a callout to code located in non-SMM/untrusted memory. A highly privileged attacker could, with active user interaction and under high complexity and present preconditions, trigger execution of attacker-controlled code in SMM, potentially compromising the system’s confidentiality, integrity, and availability.
