# Intel TDX MigTD: uninitialized virtio-vsock handling allows denial of service and corruption

Link for people: https://infrastack.ai/live/CVE-2026-63028 (this .md is for agents)

Intel's TDX Migration Trust Domain (MigTD) mishandles virtio-vsock stream data because a value is not initialized before use. A local system software adversary can cause a denial of service or corrupt data inside the trust domain.

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

## From the sources

Improper initialization in the MigTD virtio-vsock stream handling 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 data corruption. 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 (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
