Descriptions
The I/O implementation for block devices in the Linux kernel before 2.6.33 does not properly handle the CLONE_IO feature, which allows local users to cause a denial of service (I/O instability) by starting multiple processes that share an I/O context.
La implementación I/O para dispositivos de bloque en el núcleo de Linux anteriores a v2.6.33 no maneja adecuadamente la característica CLONE_IO, lo cual permite a usuarios locales causar una denegación de servicio (inestabilidad I/O) arrancando múltiples procesos que comparten un contexto I/O.
