Descriptions
The init_posix_timers function in kernel/posix-timers.c in the Linux kernel before 2.6.31-rc6 allows local users to cause a denial of service (OOPS) or possibly gain privileges via a CLOCK_MONOTONIC_RAW clock_nanosleep call that triggers a NULL pointer dereference.
La función init_posix_timers en kernel/posix-timers.c en el kernel de linux anteriores a v2.6.31-rc6 permite a usuarios locales provocar una denegación de servicio (OOPS) o posiblemente conseguir privilegios a través de una llamada CLOCK_MONOTONIC_RAW clock_nanosleep que provoca una desreferencia a un puntero NULL.
