{"id":"CVE-2026-32672","kind":"vulnerability","aliases":["CVE-2026-32672"],"related":[],"title":"Intel NPU driver: null pointer flaw lets a local user crash the system","description":"Null pointer dereference for the Intel(R) NPU Drivers before version 32.0.100.4778 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 (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.","summary":"A null pointer dereference in Intel's NPU device driver lets a logged-in local user crash the system.
