Summary
Improper buffer restrictions in Intel NPU Driver for user applications (Ring 3) may allow denial of service. An unprivileged attacker with an authenticated user and a low complexity attack can cause system unavailability via local access, without user interaction.
Risk Assessment
Risk of system downtime due to denial of service, potentially affecting service availability.
Recommendation
Update Intel NPU Driver to the latest version with security fixes.
Original NVD description (English source)
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.
