DescriptionInsufficient granularity of access control in some subsystem for some Intel(R) Xeon(R) 6 Scalable processors with Intel(R) TDX may allow an information disclosure. Authorized adversary with an authenticated user combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (none) and availability (none) impacts.
