System Management Mode (SMM) is one of the most powerful execution modes in the x86 architecture and code at this level is invisible to the Hypervisor and OS-level protections, including anti-cheat engines and anti-virus systems. While the BIOS ecosystem's complexity has led to a multitude of vulnerabilities in firmware over time, vendors are now making strides in delivering patches with greater speed and efficiency. Unfortunately, these efforts are not enough in the presence of a CPU vulnerability.
