Synopsis :

The remote host is vulnerable to a local privilege escalation attack.

Description :

The version of the Intel BIOS on the remote host is vulnerable to an
unspecified privilege escalation attack. Software running in ring 0
could potentially change code running in System Management Mode (SMM).

SMM is a privileged operating system that runs independently from the
system's operating system. A local attacker could exploit this to
run malicious code that may be undetectable from the operating system.
