Escalation of Privilege Vulnerability in Intel(R) TDX Migration Trust Domain

CVE-2026-56759

What is CVE-2026-56759?

The vulnerability arises from improper input validation in the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0 of the hypervisor. This could enable an adversary with privileged access to leverage a low-complexity attack to potentially escalate privileges, leading to data corruption. Local access is required to exploit this weakness, which may not necessitate special internal knowledge or user interaction. The influence on system integrity is notably concerning, as it could compromise the integrity of the affected system.
