Description of problem:

Problem description from Nick Piggin:

<cite>

Hi,

I have done an audit of some code and found security problems in several
drivers and some core code as well. I have only verified it is a problem and
patched it, but not explored the severity of the problem. However, it could be
anything up to allowing a local user to have read/write access of arbitrary
kernel memory.

Red Hat would like to thank Nick Piggin for responsibly disclosing this issue.

CVE-2008-0007 description:

Linux kernel before 2.6.22.17, when using certain drivers that register a fault
handler that does not perform range checks, allows local users to access kernel
memory via an out-of-range offset.
