Since arg_map->size is updated to a non-zero value before memory\nallocation, free_choose_arg_map() will iterate over arg_map->args and\ndereference a NULL pointer.\n\nTo prevent this potential NULL pointer dereference and make\nfree_choose_arg_map() more resilient, add checks for pointers before\niterating."},{"lang":"es","value":"En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\n\nlibceph: hacer free_choose_arg_map() resistente a la asignación parcial\n\nfree_choose_arg_map() puede desreferenciar un puntero NULL si su llamador falla después de una asignación parcial.\n\nPor ejemplo, en decode_choose_args(), si la asignación de arg_map->args falla, la ejecución salta a la etiqueta fail y se llama a free_choose_arg_map().
