How can I check if there are third-party or unofficial kernel module installed on my system?

Use the lsmod command to see what kernel modules are loaded in the kernel. Because Red Hat only delivers open source kernel modules check the license field of every loaded module by modinfo <module-name> command. If the license of some modules shows Proprietary, the module is not delivered by Red Hat. For example:
# modin...Subscriber exclusive content
A Red Hat subscription provides unlimited access to our knowledgebase, tools, and much more.
