Descriptions

The Performance Events subsystem in the Linux kernel before 3.1 does not properly handle event overflows associated with PERF_COUNT_SW_CPU_CLOCK events, which allows local users to cause a denial of service (system hang) via a crafted application.

El subsistema Performance Events en el kernel de Linux antes de v3.1 no trata correctamente los desbordamientos de eventos asociados con eventos PERF_COUNT_SW_CPU_CLOCK, lo que permite a usuarios locales causar una denegación de servicio (bloqueo del sistema) a través de una aplicación modificada.
