The nvme_host_get_hostid() and nvme_host_get_hostnqn() functions can return NULL when the host configuration is incomplete or invalid. Using strdup() directly on these return values causes a segmentation fault when NULL is passed to strdup(). Replace strdup() calls with xstrdup() to safely handle NULL input values.
