Hello and thanks for report.
It shouldn't be updated I believe as boot entries are located here: /boot/loader/entries/
Do you have new kernel available in GRUB?

/boot/loader/entries/ is being updated during "yum update",

[[email protected] ~]# ls -l /boot/loader/entries/

however /boot/grub2/grub.cfg is not.
On reboot, the system is not loading the new kernel. /boot/grub2/grub.cfg was not reconfigured with the new kernel's details.
After running "grub2-mkconfig -o /boot/grub2/grub.cfg", /boot/grub2/grub.cfg is configured with the new kernel's details and the new kernel is loaded on reboots.

Hope that clarifies what I am seeing.

Thank you.
