- Summary
- netfilter: nf_nat: unregister and release hooks on error
- Details
-
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.
