Descriptions

The Linux kernel 2.6.24 and 2.6.25 before 2.6.25.9 allows local users to cause a denial of service (memory consumption) via a large number of calls to the get_user_pages function, which lacks a ZERO_PAGE optimization and results in allocation of "useless newly zeroed pages."

El núcleo de Linux 2.6.24 y 2.6.25 versiones anteriores a 2.6.25.9 permite a usuarios locales provocar una denegación de servicio (consumo de memoria) a través de un número largo de llamadas a la función get_user_pages, la cual carece de optimización ZERO_PAGE y resulta en la asignación de "páginas puestas a cero recientemente sin uso".
