Descriptions

The USB subsystem in the Linux kernel before 2.6.36-rc5 does not properly initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel stack memory via vectors related to TIOCGICOUNT ioctl calls, and the (1) mos7720_ioctl function in drivers/usb/serial/mos7720.c and (2) mos7840_ioctl function in drivers/usb/serial/mos7840.c.

El subsistema USB del kernel de Linux en versiones anteriores a la 2.6.36-rc5 no inicializa apropiadamente miembros de estructuras, lo que permite a usuarios locales obtener información potencialmente confidencial de la memoria de la pila del kernel a través de vectores relacionados con llamadas ioctl TIOCGICOUNT, y la (1) función mos7720_ioctl de drivers/usb/serial/mos7720.c y (2) mos7840_ioctl de drivers/usb/serial/mos7840.c.
