CVE-2026-20731: Denial of Service in Intel(R) NPU Driver
Improper buffer restrictions for the Intel(R) NPU Driver for all versions 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 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.
AI Analysis
Technical Summary
This vulnerability involves improper buffer restrictions in the Intel(R) NPU Driver for all Ring 3 user application versions. An unprivileged adversary with authenticated local access can exploit this low-complexity flaw to cause a denial of service condition. The CVSS 4.0 score is 6.9, reflecting medium severity with high impact on availability and low impact on integrity. There is no indication of confidentiality impact. No vendor advisory or patch information is available, and no known exploits are reported in the wild.
Potential Impact
The vulnerability can cause denial of service, impacting system availability. There is no direct impact on confidentiality and only low impact on integrity. The denial of service could disrupt normal operation of the Intel NPU Driver and dependent systems or applications.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit local access to trusted users and monitor for unusual system behavior related to the Intel NPU Driver.
