# Intel TDX MigTD: unchecked return value lets a privileged user deny service

Link for people: https://infrastack.ai/live/CVE-2026-62920 (this .md is for agents)

The Intel TDX Migration Trust Domain (MigTD) error handling ignores a function's return value, so a privileged system-software user can trigger a denial of service. The impact is availability only, with no confidentiality or integrity loss.

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

## From the sources

Unchecked return value in the MigTD error handling for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow a denial of service. System software adversary with a privileged 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.
