Description

Active debug code for some Intel UEFI reference platforms within Ring 0: Kernel may allow a denial of service and escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable data alteration. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (high) and availability (high) impacts.
