CVE-2026-20754: Denial of Service in Intel(R) NPU Drivers
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.
AI Analysis
Technical Summary
This vulnerability involves improper conditions checking in firmware for certain Intel(R) NPU Drivers operating at Ring 1 privilege level. It allows a local, authenticated, unprivileged attacker to cause a denial of service by exploiting the flawed firmware logic. The attack complexity is low and does not require user interaction or special knowledge. The CVSS 4.0 base score is 6.9, reflecting medium severity with high impact on availability but no impact on confidentiality and low impact on integrity. No remediation level or patch information is currently available.
Potential Impact
Successful exploitation results in denial of service affecting system availability. There is no impact on confidentiality and only low impact on integrity. The vulnerability requires local authenticated access and has low attack complexity. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict local access to trusted users and monitor for unusual system behavior related to Intel NPU Drivers. No vendor advisory or patch links are currently provided.
