Hello,
    I am still new to xen, and was just wondering how people handle
updating their kernels for xen.

I install a new version and adjust my grub config.

More specifically for those that build
their kernels from source.  Are there patches available or do you have
to recompile your kernels whenever and exploit is found?

You mean binary patches? Why do you think it's open _source_?

So yes, you have to use the binary packages, or compile each new
version, each new source patch. Additionally, the xen patches are
always made against a specific kernel version. That means, if in
kernel 2.6.16 an issue is found, you most probably have to wait until
the xen developers release a xen patch version for the new, fixed,
upstream kernel.
