How do I find the version of a kernel module (*.ko files located in /lib/modules/... directory) in Linux server?

You need to use the modinfo command to display information about a Linux Kernel module. The syntax is as follows:

 
modinfo Module-Name-Here
 

To list loaded modules, enter:
# lsmod
# lsmod | less

Sample outputs:
