# Intel TDX MigTD: virtio-serial array index flaw allows denial of service

Link for people: https://infrastack.ai/live/CVE-2026-59771 (this .md is for agents)

The MigTD migration trust domain's virtio-serial driver does not validate an array index, so a privileged system-software adversary can crash it. The impact is denial of service only, with no confidentiality or integrity loss stated.

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

## From the sources

Improper validation of array index in the MigTD's virtio-serial driver 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.
