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

batman-adv: dat: avoid unaligned fault in IP extraction

Independent of the alignment of the ARP packet in the SKB, either the
batadv_arp_ip_src or the batadv_arp_ip_dst will have an unaligned access
(on HW without native unaligned read support).

Use get_unaligned() to handle this properly on all architectures.
