# Intel TDX MigTD: weak access control lets an attacker escalate privilege

Link for people: https://infrastack.ai/live/CVE-2026-57892 (this .md is for agents)

The MigTD v2 policy evaluation engine in Intel's TDX Migration Trust Domain does not restrict access finely enough, so a flaw in the hypervisor can allow privilege escalation. An attacker on an adjacent network with no credentials could read and modify confidential data of the affected system.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:MigTD affected < 0.7.2 fixed 0.7.2

## How to check

Check the MigTD reference software version your TDX platform or cloud image uses. Any version before 0.7.2 is affected. Ask your platform or cloud vendor which MigTD build they ship.

## Fix

Update Intel TDX Migration Trust Domain (MigTD) to version 0.7.2 or later (https://github.com/intel/MigTD/releases/tag/v0.7.2).

- [fix] intel/MigTD v0.7.2 https://github.com/intel/MigTD/releases/tag/v0.7.2

## From the sources

Insufficient granularity of access control in the MigTD v2 policy evaluation engine for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an escalation of privilege. Network adversary with an unauthenticated user combined with a high complexity attack may enable escalation of privilege. 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 (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (none) impacts.
