# Intel TDX MigTD virtio-serial driver leaks memory, enabling local denial of service

Link for people: https://infrastack.ai/live/CVE-2026-60020 (this .md is for agents)

The MigTD virtio-serial driver in Intel's TDX Migration Trust Domain does not free memory after its useful lifetime, so memory is leaked. A privileged local user on the system can exhaust resources and cause a denial of service.

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

## From the sources

Missing release of memory after effective lifetime in the MigTD 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 (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
