# Intel TDX MigTD: off-by-one in vmcall_raw lets local attacker corrupt data

Link for people: https://infrastack.ai/live/CVE-2026-61469 (this .md is for agents)

An off-by-one error in the vmcall_raw transport of Intel's TDX Migration Trust Domain (MigTD) can be triggered from Ring 0 by a system software adversary. The flaw may allow denial of service and data corruption inside the trust domain.

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

## From the sources

Off-by-one error in the MigTD's vmcall_raw transport 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.
