CVE-2014-4171

Estado: ModificadaMedia (4.7)—

mm/shmem.c en el kernel de Linux hasta 3.15.1 no implementa debidamente la interacción entre la notificación del rango y la creación de agujeros, lo que permite a usuarios locales causar una denegación de servicio (apropiación del i_mutex) mediante la llamada de sistema mmap para acceder a un agujero, tal y como fue demostrado mediante la interferencia con la actividad shmem intencionada a través del bloqueo del completado de (1) una llamada MADV_REMOVE madvise o (2) una llamada FALLOC_FL_PUNCH_HOLE fallocate.

CVSS
