CVE-2026-57890 · Severity: info · Published 2026-11-10

Intel's TDX Migration Trust Domain (MigTD) is a hypervisor component that provides security for virtual machine migration in trusted execution environments. A flaw in the SPDM responder's exception handling could allow an unauthenticated attacker over the network to trigger improper cleanup and read sensitive data from hypervisor memory. This could compromise the confidentiality of the entire system including guest virtual machines and their data.
