Lifecycle Timeline
1DescriptionCVE.org
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.
AnalysisAI
Denial of service in Intel(R) NPU Driver affects all versions via an improper conditions check (CWE-754) reachable from Ring 3 (user applications). A locally authenticated, low-privileged user can trigger the flaw without any special attack prerequisites or user interaction, resulting in high availability impact to the vulnerable system. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a locally authenticated user-level session (Ring 3 / user application space) on a system running an affected version of the Intel NPU Driver. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.9 reflects a moderate-severity, locally-exploitable DoS. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary remediation is to apply the updated Intel NPU Driver version referenced in Intel Security Advisory INTEL-SA-01456 at https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01456.html; no specific fix version number is independently confirmed in the available data beyond the advisory reference itself, so consult the advisory directly for the exact patched driver version. … Detailed patch versions, workarounds, and compensating controls in full report. |
