MIGTD · CVE-2026-57890 · Infrastructure
FIX → 0.7.2 ✓ verified
Intel's MigTD component, which handles migration of confidential VMs under TDX, does not clean up properly when an exception is thrown in its SPDM responder. A network attacker without credentials can read data exposed by this, with confidentiality impact only.

Affects deployments of Intel TDX live migration that run the MigTD (Migration Trust Domain) reference software before version 0.7.2. Intel describes the flaw as an unauthenticated network attacker reaching the MigTD's SPDM responder, which fails to clean up after an exception and can expose data (confidentiality only). Hosts and cloud providers running TDX confidential VMs with migration enabled should check; anyone not using TDX migration can skip it.

0.7.2 is affectedUpgrade to 0.7.2
Improper cleanup on thrown exception in the MigTD's SPDM responder for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an information disclosure. Network adversary with an unauthenticated user combined with a low complexity attack may enable data exposure. This result may potentially occur via network 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 (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
