Use of Uninitialized Variable in Intel TDX Module Causes Data Disclosure

Publication date: 2026-02-10

Last updated on: 2026-02-10

Assigner: Intel Corporation

Description
Use of uninitialized variable for some TDX Module before version tdx1.5 within Ring 0: Hypervisor may allow an information disclosure. Authorized adversary with a privileged user combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Executive Summary

This vulnerability involves the use of an uninitialized variable in some versions of the Intel TDX Module before version tdx1.5 within Ring 0 (the hypervisor level). This flaw may allow an authorized adversary with privileged user access to potentially disclose sensitive information. The attack is complex and requires local access but does not require user interaction or special internal knowledge.

Impact Analysis

The vulnerability primarily impacts the confidentiality of the system by potentially exposing sensitive data. It does not affect the integrity or availability of the system. An attacker with high privileges and local access could exploit this to gain unauthorized information disclosure.
