I fixed a few more info leaks in linux v3.9-rc3. Unprivileged users
can use the netlink interface to exploit the following issues to
disclose kernel stack memory:

David Miller did backports for the above issues which are currently
under review and should end up in the next stable and longterm
kernels.
