Hi,
I have been working on a problem that contains a fix for a bug, not a
vulnerability, in 2.6.x kernels. Based on kernel.org info I cannot say
exactly when it was patched. Here is the patch:

I think the patch was introduced after 2.6.11, not totally sure. I can tell it was
patched by 2.6.17. I need this patch. Can anyone verify if this is included in
kernel-smp-2.6.12-2.3.legacy_FC3.x86_64.rpm for FC3 from Fedora Legacy?
Thanks. If the answer is yes, please point me to the evidence so I can show it to the
rest of the SysAdmin Team here at COSMIC. (Not that we would doubt it, but it would
be better to see it for ourselves. Paranoid mode set = 1 and so on.)
