Doc Text:
A flaw was found in MigTD (Intel Trust Domain Extensions Migration Trust Domain). An out-of-range pointer offset in the virtio-vsock implementation allows a local, privileged user to achieve privilege escalation. An attacker with host hypervisor-level access can exploit this flaw to execute unauthorized operations and gain control over the migration trust domain.

Description OSIDB Bzimport 2026-11-10 20:34:00 UTC 
Use of out-of-range pointer offset in the MigTD's virtio-vsock implementation for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. 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 (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
