# Intel TDX MigTD: buffer size error lets a hypervisor cause denial of service

Link for people: https://infrastack.ai/live/CVE-2026-61383 (this .md is for agents)

The Intel TDX Migration Trust Domain (MigTD) miscalculates a buffer size in its servtd_get_quote routine. A system software adversary with local access can cause a denial of service in the trust domain.

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

## From the sources

Incorrect calculation of buffer size in the MigTD's servtd_get_quote 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 high 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.
