- Summary
- batman-adv: dat: avoid unaligned fault in IP extraction
- Details
-
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.
