In the Linux kernel, the following vulnerability has been resolved:

mpls: Use rcu_dereference_rtnl() in mpls_route_input_rcu().

As syzbot reported [0], mpls_route_input_rcu() can be called from mpls_getroute(), where is under RTNL.

net->mpls.platform_label is only updated under RTNL.

Let's use rcu_dereference_rtnl() in mpls_route_input_rcu() to silence the splat.
