Intel TDX MigTD: uninitialized memory can leak data from hypervisor

Use of uninitialized resource in the MigTD memory for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an information disclosure. Network adversary with a privileged user combined with a low complexity attack may enable data exposure. This result may potentially occur via adjacent access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
