CVE-2026-20786: Denial of Service in Intel(R) NPU Driver
Out-of-bounds read 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 in the Intel(R) NPU Driver allows an out-of-bounds read in user-mode applications (Ring 3), which can be exploited by an unprivileged authenticated user via a local attack of low complexity. The attack does not require user interaction or special internal knowledge. The vulnerability impacts system availability, potentially causing denial of service. The CVSS 4.0 base score is 6.9, indicating medium severity. There is no vendor advisory or patch information available at this time.
Potential Impact
The vulnerability can cause denial of service, impacting system availability (high impact). There is no impact on confidentiality and only low impact on integrity as per the CVSS vector. No further impacts on confidentiality, integrity, or availability are indicated beyond the initial denial of service.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround is currently documented.
