Descriptions

The ULE process scheduler in the FreeBSD kernel gives preference to "interactive" processes that perform voluntary sleeps, which allows local users to cause a denial of service (CPU consumption), as described in "Secretly Monopolizing the CPU Without Superuser Privileges."

El programador de procesos ULE en el núcleo de FreeBSD le da preferencia a procesos "interactivos" que realizan esperas voluntarias (sleeps), lo cual permite a usuarios locales provocar una denegación de servicio (agotamiento de CPU), como se ha descrito en "Monopolizando Secretamente la CPU sin Privilegios de Superusuario" (Secretly Monopolizing the CPU Without Superuser Privileges).
