·
Updated

Insufficient verification of data authenticity for some Intel(R) Trust Domain Extensions (Intel(R) TDX) within Ring 0: Hypervisor may allow an information disclosure. A system software adversary with a privileged user access combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present without any user interaction. The potential vulnerability may impact the confidentiality (high), integrity (low) and no effect on availability. Subsequent system impacts include reduced confidentiality (low), integrity (low), and no effect on availability.
