Las implementaciones (1) pipe_read y (2) pipe_write en fs/pipe.c en un determinado backport del kernel de Linux en el paquete linux en versiones anteriores a 3.2.73-2+deb7u3 sobre Debian wheezy y el paquete kernel en versiones anteriores a 3.10.0-229.26.2 sobre Red Hat Enterprise Linux (RHEL) 7.1 no considera correctamente los efectos laterales de llamadas __copy_to_user_inatomic y __copy_from_user_inatomic fallidas, lo que permite a usuarios locales provocar una denegación de servicio (caída de sistema) o posiblemente obtener prvilegios a través de una aplicación manipulada, también conocido como un "I/O vector array overrun". NOTA: esta vulnerabilidad existe debido a una solución incorrecta para CVE-2015-1805.
