CVE-2026-57892
Intel MigTD Policy Evaluation Engine Privilege Escalation Vulnerability
Description
Insufficient granularity of access control in the MigTD v2 policy evaluation engine for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an escalation of privilege. Network adversary with an unauthenticated user combined with a high complexity attack may enable escalation of privilege. 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 (high), integrity (high) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (none) impacts.
