> DESCRIPTION

Improper handling of values for some Intel(R) Processors within Ring 0: Kernel, Hypervisor and Bare Metal OS may allow an escalation of privilege. Authorized adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present with special internal knowledge and require no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (none) impacts.
