CVE-2026-20741

Local denial of service via driver access control

Published Aug 11, 2026 · Updated Aug 11, 2026

Improper access control in Intel PROSet/Wireless WiFi Software before 24.10 allows local users to interrupt service through a device driver. The flaw resides in Ring 2 device-driver access control, but Intel has not disclosed the protected operation or input handled incorrectly. An unprivileged local process requires no user interaction or special internal knowledge; the documented consequence is availability loss, with low subsequent integrity impact.
