The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - pid: Add a judgment for ns null in pid_nr_ns __task_pid_nr_ns ns = task_active_pid_ns(current);
    pid_nr_ns(rcu_dereference(*task_pid_ptr(task, type)), ns); if (pid && ns->level <= pid->level) { Sometimes     null is returned for task_active_pid_ns. Then it will trigger kernel panic in pid_nr_ns. For example:
