What to Know

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

bonding: alb: fix uninitialized transport header access in alb_determine_nd()

alb_determine_nd() uses icmp6_hdr(skb) to inspect ICMPv6 headers.

However, in xmit paths (e.g. packets sent via AF_PACKET / raw sockets

or forwarded packets), skb->transport_header is not guaranteed to be

initialized. While pskb_network_may_pull() ensures the packet data is

linear starting from the network header, it does not set or adjust the

transport header offset.

Dereferencing icmp6_hdr(skb) can therefore access out-of-bounds memory.

Fetch the icmp6hdr directly after ipv6hdr following pskb_network_may_pull(),

and reload ipv6hdr in case pskb_may_pull() reallocated skb->head.

Also remove the unused bond argument from alb_determine_nd(). (NVD)
