In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: Fix potential data-race in __nft_obj_type_get()
nft_unregister_obj() can concurrent with __nft_obj_type_get(), and there is
not any protection when iterate over nf_tables_objects list in
__nft_obj_type_get(). Therefore, there is potential data-race of
nf_tables_objects list entry. Use list_for_each_entry_rcu() to iterate over
nf_tables_objects list in __nft_obj_type_get(), and use rcu_read_lock() in
the caller nft_obj_type_get() to protect the entire type query process.
