Doc Text:
A flaw was found in the Intel NPU Driver. This vulnerability, an out-of-bounds read, could allow a local attacker with low privileges to cause a denial of service (DoS). A denial of service means the system or application becomes unavailable to legitimate users. The flaw can be exploited by an unprivileged, authenticated user through local access without requiring user interaction or special knowledge. Successful exploitation primarily impacts the availability of the system, making it unresponsive or unusable.

Description OSIDB Bzimport 2026-08-11 16:52:47 UTC 
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.
