Descriptions

The uart_get_count function in drivers/serial/serial_core.c in the Linux kernel before 2.6.37-rc1 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 uart_get_count de drivers/serial/serial_core.c del kernel de Linux en versiones anteriores a la 2.6.37-rc1 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.
