Description
Uncaught exception for some Intel(R) TDX modules within Ring 0: Trust Domain may allow a denial of service. System software adversary with a privileged user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (high) impacts.
