Descriptions

The epoll implementation in the Linux kernel 2.6.37.2 and earlier does not properly traverse a tree of epoll file descriptors, which allows local users to cause a denial of service (CPU consumption) via a crafted application that makes epoll_create and epoll_ctl system calls.

La implementación epoll en el Kernel de Linux v2.6.37.2 y anteriores no cruza un árbol de descriptores de fichero epoll adecuadamente, lo que permite a usuarios locales provocar una denegación de servicio (consumo de CPU) a través de una aplicación manipulada que hace epoll_create y llamadas al sistema epoll_ctl.
