Doc Text:
A flaw was found in the Intel Trust Domain Extensions (TDX) Migration Trust Domain (MigTD). The MigTD Transport Layer Security (TLS) implementation fails to properly verify a return value. An unauthenticated attacker on an adjacent network can exploit this flaw to cause a Denial of Service (DoS) on the affected system.

Description OSIDB Bzimport 2026-11-10 19:37:56 UTC 
Unchecked return value in the MigTD's TLS implementation for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent 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.
