CVE-2026-24911

Adjacent denial of service via kernel stack overflow

Published Aug 11, 2026 · Updated Aug 11, 2026

Stack-based buffer overflow in Intel PROSet/Wireless WiFi Software before 24.30 allows remote attackers to interrupt systems via adjacent access. Intel identifies the flaw in a Ring 0 kernel component but has not disclosed the affected routine, input field, or copying operation that overwrites the stack buffer. No authentication or user interaction is required, and the documented consequence is limited to system availability.
