Unknown from the sources.
No fix yet, per the sources.
Detection of error condition without action in the MigTD's vmcall_raw transport for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable data corruption. This result may potentially occur via local access when attack requirements are present without 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 (none), integrity (none) and availability (none) impacts.
