CVE-2026-20769: Denial of Service in Intel(R) NPU Driver
Improper conditions check 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 arises from improper conditions checking in the Intel(R) NPU Driver for all Ring 3 user application versions. An unprivileged adversary with authenticated local access can exploit this flaw to cause denial of service, impacting system availability. The attack requires no user interaction and does not require special internal knowledge. The CVSS 4.0 base score is 6.9, reflecting medium severity with low attack complexity and no user interaction needed. No vendor advisory or patch information is available at this time.
Potential Impact
The primary impact is denial of service, affecting system availability (high impact). There is no impact on confidentiality and only low impact on integrity as per the CVE description. Subsequent impacts on confidentiality, integrity, or availability are not expected.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Monitor Intel's advisories for updates.
