I am using Ubuntu 14.04 OS as host and running Kali Linux virtually. When I try to install the Guest Additions, error occurs and upon tail the error log the following message is displayed

Creating udev rule for the Guest Additions kernel module. /tmp/vbox.0/Makefile.include.header:97: * Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again. Stop.

Ubuntu Kernel Release
3.13.0-30-generic

Kali Linux Kernel Release
3.14-kali1-686-pae

Is it because of kernel release conflict?

There is no conflict between your guest and your host. That the whole idea of virtual machines . Your problem is within your guest. You do not have your kernel headers installed in your guest.

Thanks a lot. I solved the problem.

Moved to "Linux Guests" since the OP's Linux Host was not relevant to the question asked.
