Description

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_objectslist in __nft_obj_type_get(). Therefore, there is potential data-raceof nf_tables_objects list entry.Use list_for_each_entry_rcu() to iterate over nf_tables_objectslist in __nft_obj_type_get(), and use rcu_read_lock() in the callernft_obj_type_get() to protect the entire type query process.
