In the Linux kernel, the following vulnerability has been resolved:
arp: do not assume dev_hard_header() does not change skb->head
arp_create() is the only dev_hard_header() caller making assumption about skb->head being unchanged.
A recent commit broke this assumption.
Initialize @arp pointer after dev_hard_header() call.
