Descriptions

The Linux kernel before 2.6.37 does not properly implement a certain clock-update optimization, which allows local users to cause a denial of service (system hang) via an application that executes code in a loop.

El kernel de Linux antes de v2.6.37 no aplica la optimización de una actualización de reloj, lo que permite a usuarios locales provocar una denegación de servicio (bloqueo del sistema) a través de una aplicación que ejecuta código en un bucle.
