CVE-2026-20752· NVD / CVE Program· CNA intel

Improper authentication for some Intel(R) PROSet/Wireless WiFi Software within Ring 0: Kernel may allow an information disclosure.

Improper authentication for some Intel(R) PROSet/Wireless WiFi Software within Ring 0: Kernel may allow an information disclosure. System software adversary with a privileged user combined with a low complexity attack may enable data exposure. 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 (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Root cause

Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

Vulnerable

Fixed

1const admin = express.Router();2admin.use(requireSession, requireRole("admin"));3
