CVE-2026-40426
Quick assessment
Affected
n/a Intel(R) NPU Driver software
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在版本 1.33.0 之前的 Intel(R) NPU 驱动程序软件中，Ring 3（用户模式）存在整数下溢（即回绕）漏洞。该漏洞可能允许非特权攻击者利用已认证用户身份，通过低复杂度的攻击方式引发拒绝服务（DoS）。在满足攻击条件且无需特殊内部知识的情况下，攻击者可通过本地访问实施攻击，且无需用户交互。该潜在漏洞可能对受影响系统的机密性（低）、完整性（低）和可用性（高）造成影响，进而导致系统后续出现机密性（无）、完整性（无）和可用性（无）的进一步影响。

Vulnerability Description
Integer underflow (wrap or wraparound) for the Intel(R) NPU Driver software before version 1.33.0 within Ring 3: User Applications 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 present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
