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.
