CVE-2008-3534

Estado: ModificadaMedia (4.9)—

La función shmem_delete_inode de mm/shmem.c en la implementación the tmpfs de Linux kernel versiones anteriores a 2.6.26.1 permite a usuarios locales provocar una denegación de servicio (caída del sistema) a través de una determinada secuencia de operaciones de ficheros de crear, eliminar y sobrescribir, como lo demostrador por el programa insserv, relacionado con la asignación de "páginas sin uso" y mantenimiento inadecuado de la cuenta i_blocks.
