## Description

In the Linux kernel, the following vulnerability has been resolved:  vxlan: Fix NPD when refreshing an FDB entry with a nexthop object  VXLAN FDB entries can point to either a remote destination or an FDB nexthop group. The latter is usually used in EVPN deployments where learning is disabled.  However, when learning is enabled, an incoming packet might try to refresh an FDB entry that points to an FDB nexthop group and therefore does not have a remote. Such packets should be dropped, but they are only dropped after dereferencing the non-existent remote, resulting in a NPD [1] which can be reproduced using [2].  Fix by dropping such packets earlier. Remove the misleading comment from first_remote_rcu().
