CVE-2026-57893 · Severity: info · Published 2026-11-10

Intel's TDX Migration Trust Domain (MigTD) is a hypervisor-level component that handles secure migration of encrypted virtual machines. A flaw in the SPDM responder's state tracking could allow a privileged attacker to corrupt data or escalate privileges. This affects the integrity of the entire virtualized environment and any guest systems running on the hypervisor.

## Technical details

The vulnerability involves incomplete internal state distinction in MigTD's SPDM (Security Protocol and Data Model) responder running at Ring 0. An adjacent network attacker with system software privileges and low attack complexity can trigger data corruption through improper state tracking. The advisory lists multiple CVEs in this family; this specific issue (incomplete state distinction) may lead to privilege escalation or information disclosure depending on the state confusion.
