Kernel security update required or not?

[Bojan Smojver]

According to this: http://lwn.net/Articles/367443/, latest kernel
updates have security fixes (the second one appears on the 2.6.31.9
list).

Is this something that has been backported to current F-12 kernels (I
don't see it in changelog), or do we need a security update for F-12
here?
