Descriptions

The ntty_ioctl_tiocgicount function in drivers/char/nozomi.c in the Linux kernel 2.6.36.1 and earlier does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call.

La función ntty_ioctl_tiocgicount de drivers/char/nozomi.c del kernel de Linux en versiones anteriores a la 2.6.36.1 y anteriores no inicializa apropiadamente un miembro de una determinada estructura, lo que permite a usuarios locales obtener información potencialmente confidencial de la memoria de la pila del kernel a través de una llamada ioctl TIOCGICOUNT.
