Comment 13 Mark J. Cox (Product Security) 2008-02-10 11:42:11 EST
There was a bit of confusion as the code changed since introduction 2.6.17, so
Red Hat Enterprise Linux kernels had code different to upstream.

CVE-2008-0009 and CVE-2008-0010 only affected kernels 2.6.22+ so Red Hat
Enterprise Linux was not affected

CVE-2008-0600 affected kernels 2.6.17+ so affects Red Hat Enterprise Linux 5. 
Closing this CVE-2008-0009 bug as it doesn't affect RHEL.
