The nfnetlink_rcv_batch function in net/netfilter/nfnetlink.c in the Linux
kernel before 4.5 does not check whether a batch messageβs length field is
large enough, which allows local users to obtain sensitive information from
kernel memory or cause a denial of service (infinite loop or out-of-bounds
read) by leveraging the CAP_NET_ADMIN capability.
