Secure Boot versus Ksplice.
I have been attending many talks on Secure Boot.  The basic idea behind secure boot is to ensure that the bios/bootloader and kernel have not been hacked.  My understanding of how this is done is everything is signed and verified during the bootup.  Nothing can run in the kernel that was not signed and verified.  

Then we Oracle pushing Ksplice.

I can't help but ask the question?

Is ksplice a security disaster waiting to happen?

It doesn't seem to be at odds, because if your kernel is signed, the update could be signed as well. You just need to maintain the chain of trust for the Ksplice updates.
