DescriptionProtection mechanism failure for some Intel(R) Data Center Attestation Primitives (Intel(R) DCAP) may allow information disclosure. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable data exposure. This result may potentially occur via network access when attack requirements are present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (high) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (none) and availability (none) impacts.
