Nothing protects you against kernel bugs. PaX (part of GRSEC) does some
things which can theoretically protect against some kernel bugs, I am not
sure whether it would have done any good against any of the recent kernel
bugs (I guess if it did then we would have heard about it ;).
Any improvement to system security which can make it more difficult for a
hostile remote user to run code on your system will make it more difficult
for a local kernel bug to be exploited. SE Linux, exec-shield, GRSEC, etc
all help in this regard.
