Descriptions

The fallocate implementation in the GFS2 filesystem in the Linux kernel before 3.2 relies on the page cache, which might allow local users to cause a denial of service by preallocating blocks in certain situations involving insufficient memory.

La implementación de fallocate en el sistema de ficheros GFS2 de los kernel Linux anteriores a v3.2 confía en la caché, pudiendo permitir a usuarios locales provocar una denegación de servicio mediante la pre-asignación de bloques que suponen ciertas situaciones de memoria insuficiente.
