Intel TDX MigTD: write-what-where flaw lets a privileged local user escalate

Write-what-where condition in the MigTD for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an information disclosure and escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
