**Name of the Vulnerable Software and Affected Versions** libndp versions prior to 1.6 **Description** The issue concerns the validation of the origin of Neighbor Discovery Protocol (NDP) messages. This allows remote attackers to conduct man-in-the-middle attacks or cause a denial of service by advertising a node as a router from a non-local network, leading to network connectivity disruption. **Recommendations** For libndp versions prior to 1.6, update to version 1.6 or later to resolve the issue. As a temporary workaround, consider restricting access to the network to minimize the risk of exploitation.
