Descriptions

The viafb_ioctl_get_viafb_info function in drivers/video/via/ioctl.c in the Linux kernel before 2.6.36-rc5 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a VIAFB_GET_INFO ioctl call.

La función viafb_ioctl_get_viafb_info en drivers/video/via/ioctl.c en el kernel de Linux anterior a v2.6.36-rc5 no inicializa correctamente un valor de una determinada estructura, lo que permite a usuarios locales obtener información sensible de la pila de la memoria del kernel a través de una llamada ioctl VIAFB_GET_INFO .
