Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: staging: vchiq_arm: Se corrige un posible NPR del subproceso keep-alive. Si vchiq_platform_conn_state_changed() no se llama nunca o falla antes de la eliminación del controlador, ka_thread no será un puntero válido a una task_struct. Por lo tanto, realice las comprobaciones necesarias antes de llamar a kthread_stop para evitar un bloqueo.
