CVE-2026-20754 Details
Description
Improper conditions check in some firmware for some Intel(R) NPU Drivers within Ring 1: Device Drivers may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. 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 (none), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
A denial-of-service vulnerability has been identified in some Intel NPU Drivers for both Linux and Windows. The issue arises from improper condition checks in the firmware, which may allow an unprivileged software adversary with an authenticated user to disrupt service. This vulnerability can potentially be exploited through local access, without special internal knowledge, and requires no user interaction. The vulnerability has a low impact on system integrity and none on confidentiality, but a high impact on availability.
Users are advised to update the Intel NPU Driver for Linux to version 1.26.0 or later. For Windows, the driver should be updated to version 32.0.100.4511 or later. These updates are available for download from the Intel Linux NPU Driver Releases page and the Intel Download Center, respectively.
