kernel: drivers/usb/serial/mos*.c: reading uninitialized stack memory

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 mos7720ioctl function in...
