[Centos] kernel update

an updated kernel was released in U#..however when i did yum 
update it did not grab the actual kernel only kernel utils..What 
do i need to do to make yum grab the kernel as well during the 
update process?

My "Foundation" verse:
Isa 54:17  No weapon that is formed against thee shall prosper; 
and every tongue that shall rise against thee in judgment thou 
shalt condemn. This is the heritage of the servants of the LORD, 
and their righteousness is of me, saith the LORD.
