CVE-2024-26342Public exploitNetwork attack vector

Unauthenticated router crash via null pointer dereference

Published Feb 28, 2024 · Updated Apr 22, 2025

Null pointer dereference in ASUSTeK RT-AC68U 3.0.0.4.384.82230 allows remote attackers to crash the router via a network packet. The httpd binary passes a null-derived v6+2 pointer to strstr without validating it, causing the web service and router to crash. No authentication or user interaction is required; the demonstrated outcome is an availability loss, with no reported data exposure or modification.
