Denial of Service in Intel TDX Migration Trust Domain

Publication date: 2026-11-10

Last updated on: 2026-11-10

Assigner: Intel Corporation

Description
Improper validation of array index in the MigTD's virtio-serial driver 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.
