CVE-2026-22988

Summary

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.
