kernel: NULL pointer dereference in af_netlink.c:__netlink_ns_capable() allows for denial of service

The Linux kernel was found to be vulnerable to a NULL pointer dereference bug in the netlinknscapable function in the net/netlink/afnetlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service...
