Descriptions
kernel/trace/ftrace.c in the Linux kernel before 2.6.35.5, when debugfs is enabled, does not properly handle interaction between mutex possession and llseek operations, which allows local users to cause a denial of service (NULL pointer dereference and outage of all function tracing files) via an lseek call on a file descriptor associated with the set_ftrace_filter file.
kernel/trace/ftrace.c en el kernel Linux anterior a la versión 2.6.36-rc5, cuando está habilitado debugfs, no maneja adecuadamente la interacción entre la posesión mutex y operaciones llseek, lo que permite a usuarios locales provocar una denegación de servicio (interrupción de todas las funciones de rastreo de archivos) mediante una llamada lseek en un descriptor de fichero asociado con el fichero set_ftrace_filter.
