Affects Intel TDX deployments that run the MigTD (Migration Trust Domain) reference software before version 0.7.2, which is used for live migration of trust domains. Intel rates the flaw critical (CVSS 4.0 9.4): an unauthenticated attacker with adjacent network access could escalate privilege and possibly run code. Teams not using Intel TDX or MigTD live migration can skip it.

0.7.2 is affectedMissing critical step in authentication in the MigTD SPDM rebind implementation for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an escalation of privilege and information disclosure. Network adversary with an unauthenticated user combined with a low complexity attack may enable remote code execution. 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 (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (high) impacts.
