A vulnerability has been identified in Linux Kernel, which could be exploited by local attackers to cause a denial of service. This issue is caused by a NULL pointer dereference error in the "rt6_fill_node()" [net/ipv6/route.c] function when no IPv6 input device is in use, which could allow malicious users to panic a vulnerable system via a specially crafted command, creating a denial of service condition.
