That difference isn't a problem: The 2.6.25 points to the headers used during the build, the system can in the mean time have gone up a few versions (2.6.43 in your example). LFS is a freshly install and bash was build against the 3.5.2 kernel headers and no kernel updates are done so I expected to see that.
I can't come up with anything else at the moment.
