Descriptions

The inotify_read function in the Linux kernel 2.6.27 to 2.6.27.13, 2.6.28 to 2.6.28.2, and 2.6.29-rc3 allows local users to cause a denial of service (OOPS) via a read with an invalid address to an inotify instance, which causes the device's event list mutex to be unlocked twice and prevents proper synchronization of a data structure for the inotify instance.

La función inotify_read en el kernel de Linux versiones 2.6.27 hasta 2.6.27.13, 2.6.28 hasta 2.6.28.2 y 2.6.29-rc3, permite a los usuarios locales causar una denegación de servicio (OOPS) por medio de una lectura con una dirección no válida en una instancia inotify, lo que causa que la exclusión mutua de la lista de eventos del dispositivo se desbloquee dos veces e impida la sincronización apropiada de una estructura de datos para la instancia inotify.
