Privilege Escalation via Missing Protection in Intel Quick Assist Kernel

Publication date: 2026-02-10

Last updated on: 2026-02-10

Assigner: Intel Corporation

Description
Missing protection mechanism for alternate hardware interface in the Intel(R) Quick Assist Technology for some Intel(R) Platforms within Ring 0: Kernel 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 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 missing protection mechanism for an alternate hardware interface in Intel Quick Assist Technology on some Intel platforms. It exists within Ring 0 (the kernel level), which means it affects the core of the operating system.

A system software adversary who already has privileged user access and some special internal knowledge can exploit this vulnerability with a low complexity attack to escalate their privileges further. This attack requires local access and no user interaction.

Impact Analysis

The vulnerability can lead to an escalation of privilege, allowing an attacker with some level of privileged access to gain higher privileges within the system.

It potentially impacts the confidentiality and integrity of the system at a high level, meaning sensitive information could be exposed or altered. However, it does not impact the availability of the system.
