Summary
arp: do not assume dev_hard_header() does not change skb->head
Details

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

arp: do not assume devhardheader() does not change skb->head

arpcreate() is the only devhard_header() caller making assumption about skb->head being unchanged.

A recent commit broke this assumption.

Initialize @arp pointer after devhardheader() call.
