Doc Text:
A flaw was found in the Intel Trust Domain Extensions (TDX) Migration Trust Domain (MigTD). Due to an unchecked return value in error handling routines within the hypervisor, a local user with administrative privileges can trigger an unhandled failure. This flaw results in a Denial of Service (DoS), causing the affected system or migration services to become unavailable.

Description OSIDB Bzimport 2026-11-10 20:42:44 UTC 
Unchecked return value in the MigTD error handling 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 (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
