Race Condition in Intel TDX Module Enables Privilege Escalation

Publication date: 2026-02-10

Last updated on: 2026-02-10

Assigner: Intel Corporation

Description
Race condition for some TDX Module 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 with 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 (none), integrity (none) and availability (none) impacts.

Executive Summary

This vulnerability is a race condition in some Intel TDX Modules operating within Ring 0, which is the hypervisor level. It allows a system software adversary who already has privileged user access to potentially escalate their privileges further. The attack is of low complexity and can be executed locally without user interaction or special internal knowledge.

Impact Analysis

The vulnerability can impact the confidentiality and integrity of the affected system at a high level. However, it does not affect the availability of the system. This means sensitive information could be exposed or altered by an attacker who exploits this vulnerability, but the system's availability remains unaffected.
