Descriptions
The journal_unmap_buffer function in fs/jbd2/transaction.c in the Linux kernel before 3.3.1 does not properly handle the _Delay and _Unwritten buffer head states, which allows local users to cause a denial of service (system crash) by leveraging the presence of an ext4 filesystem that was mounted with a journal.
La función journal_unmap_buffer en fs/jbd2/transaction.c en el kernel de linux anterior a v3.3.1 no maneja correctamente el "buffer head states" _Delay y _Unwritten, permitiendo a usuarios locales causar una denegación de servicio aprovechándose de la presencia de un sistema de ficheros ext4 que está montado con journal
