CVE-2024-27019

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.

Por lo tanto, existe una posible ejecución de datos de la entrada de la lista nf_tables_objects. Utilice list_for_each_entry_rcu() para iterar sobre la lista nf_tables_objects en __nft_obj_type_get(), y utilice rcu_read_lock() en el llamador nft_obj_type_get() para proteger todo el proceso de consulta de tipos.
