Infinite Loop in Intel TDX Migration Trust Domain

Publication date: 2026-11-10

Last updated on: 2026-11-10

Assigner: Intel Corporation

Description
Loop with unreachable exit condition ('infinite loop') in the MigTD's GetQuote for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow a denial of service. System software adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Executive Summary

This is an infinite loop vulnerability in Intel's MigTD (Migration Trust Domain) component of Intel TDX. It allows a denial of service attack where a low-complexity local access exploit can cause the system to hang indefinitely without requiring special privileges or user interaction.

Impact Analysis

The vulnerability may cause system instability or crashes, leading to service disruptions. Since it affects the hypervisor layer, it could impact all guest operating systems running on the vulnerable system, resulting in downtime and potential data loss.

Compliance Impact

This vulnerability could lead to violations of availability requirements in GDPR and HIPAA, as it may cause system unavailability. Organizations may face compliance penalties if critical systems become inaccessible due to denial of service conditions.

Mitigation Strategies

Apply vendor patches or updates for Intel TDX Migration Trust Domain (MigTD) to address the infinite loop vulnerability in GetQuote. Monitor Intel security advisories for updates and restrict local access to untrusted users to reduce attack surface.
