Descriptions

The shmem_delete_inode function in mm/shmem.c in the tmpfs implementation in the Linux kernel before 2.6.26.1 allows local users to cause a denial of service (system crash) via a certain sequence of file create, remove, and overwrite operations, as demonstrated by the insserv program, related to allocation of "useless pages" and improper maintenance of the i_blocks count.

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.
