Or maybe they used a Fedora kernel :)
They used vanialla kernel

But wait...RedHat is going to do that by making it hard for Oracle to steal RedHat's kernel changes? Which Oracle wasn't doing anyways...Errrrrrr, what?
PS: what's up with Oracle's kernel, anyways? Their git tree doesn't seem to have been updated in ages:

Are you surprised? Ever since the acquisition thing, everything has practically come to a halt. Last entry of onnv (below) is just about the same timeframe unbreakable.git stopped being updated.

The risk is whether or not Nexenta and the Illumos folks have the resources to support development of drivers for newer hardware going forward... and whether or not they can count on Oracle doing Solaris source code dumps periodically to either re-base or cherry pick...

Oracle aside, various other distro kernels are based on 2.6.32-stable too. RHEL6's kernel is _not_ based on 2.6.32-stable. That said, RHEL6's kernel does contain many of the same upstream linux-2.6's "firstname.lastname@example.org" fixes that feed into 2.6.32-stable.
But due to the various 2.6.3 backports that the RHEL6.x kernel has seen the code has diverged considerably from 2.6.32-stable. This divergence is to the point that most fixes made to RHEL6's kernel are either irrelevant to or do not apply cleanly to 2.6.32-stable. The fixes would be more suitable to apply to 2.6.36-stable, 2.6.37-stable, etc. Red Hat kernel developers do mark appropriate upstream linux-2.6 fixes with: "Cc: email@example.com".
So Red Hat's fixes really do flow back to "firstname.lastname@example.org" kernels -- unfortunately (for Oracle, Novell, Ubuntu, Debian, etc) those changes are not overly useful to 2.6.32-stable based distribution kernels. NOTE: all "email@example.com" kernels do not allow new features whereas the RHEL6's kernel does.
It would require quite some surgery to backport the RHEL6.x kernel changes to 2.6.32-stable (because the implicit requisite feature surgery is _not_ possible in a "firstname.lastname@example.org" kernel). The challenge associated with trying to backport RHEL6's changes to 2.6.32-stable will only grow over time.
Oh, yeah, it does.

Oracle selectively pulls changes needed to make RHEL programs happy, then add it's own patches and packages the result. Now they will have a dilemma: either use pure RHEL source (and forget about "latest and greatest" claims) or start actually making its own distro.

But I guess RedHat is concerned that now that they're *also* using the 2.6.32 kernel, Oracle might stop bothering to maintain their own kernel from scratch and just use RHEL's with some extra patches on top, or something.

I never understood why, from a customer perspective, I'd want to use OEL instead of the "real thing" (RHEL). Plus, as big as Oracle is, RH has the bigger mindshare and expertise as far as kernel hackers and engineers (at least devoted to Linux) -- not to say Oracle doesn't have some quality people, just not as many.
I never thought OEL would really take off or be a threat to RHEL ...

Having said all that, I have no clue how Oracle is going to continue to support their kernel once they've undermined RH enough. I'm sure not many of the RH engineers want to work for oracle (apparently not many of the Sun engineers did either...). I have this impression that for Larry Ellison it's all about winning, regardless of whether he's a winner of a wasteland, rather than a large participant in a vibrant ecosystem.
