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

netfilter: nf_nat: unregister and release hooks on error

If nf_hook_entries_insert_raw() fails, the NAT hooks get never released,
resulting in a memleak.

Postpone setting nat_proto_net->nat_hook_ops when the hooks are
registered to simplify the error path to decide whether the nat hooks
need unwinding.
