Overview

Affected versions of this package are vulnerable to Information Exposure. 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.
