Running arbitrary code in SMM additionally bypasses SMM-based SPI flash protections against modifications, which can help an attacker to install a firmware backdoor/implant into BIOS. Such a malicious firmware code in BIOS could persist across operating system re-installs. Additionally, this vulnerability potentially could be used by malicious actors to bypass security mechanisms provided by UEFI firmware (for example, Secure Boot and some types of memory isolation for hypervisors).

Una ejecución de código arbitrario en el SMM también evita las protecciones de la flash SPI basadas en el SMM contra las modificaciones, lo que puede ayudar a un atacante a instalar una puerta trasera/implante de firmware en la BIOS. Dicho código de firmware malicioso en la BIOS podría persistir a través de las reinstalaciones del sistema operativo.
