Descriptions

The filesystem implementation in the Linux kernel before 3.13 performs certain operations on lists of files with an inappropriate locking approach, which allows local users to cause a denial of service (soft lockup or system crash) via unspecified use of Asynchronous I/O (AIO) operations.

La implementación del sistema de fichero en el Kernel de Linux anterior a 3.13 realizar ciertas operaciones en listas de archivos con un inapropiado bloqueo, lo que permite a usuarios locales causar una denegación de servicio (bloqueo blando 'soft lockup' o caída del sistema) a través del uso de operaciones Asynchronous I/O (AIO) no especificadas.

It was found that due to excessive files_lock locking, a soft lockup could be triggered in the Linux kernel when performing asynchronous I/O operations. A local, unprivileged user could use this flaw to crash the system.
