Information Disclosure in Intel TDX Hypervisor via Transient Execution

Publication date: 2026-02-10

Last updated on: 2026-02-10

Assigner: Intel Corporation

Description
Exposure of sensitive information during transient execution for some TDX 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 not 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 exposure of sensitive information during transient execution within Intel's TDX (Trusted Domain Extensions) technology operating at Ring 0, specifically in the hypervisor. An authorized adversary with privileged user access, combined with a high complexity attack, may be able to disclose sensitive data. The attack requires local access and special internal knowledge but does not require user interaction.

Impact Analysis

The vulnerability primarily impacts the confidentiality of the system by potentially allowing sensitive information to be exposed. It does not affect the integrity or availability of the system. The attack requires a privileged user and local access, making it less likely to be exploited remotely or by unprivileged users.
