Install Oracle and OS patch together

Hi People, I have Oracle 12c database running on RHEL 7.

Is it ok to install OS patch and then Oracle database patch one after another and then reboot the server later when I complete the oracle patch installation?

I mean, I will not reboot the server after the OS/kernel patch installed but then I will continue to install the oracle patch and then only I will reboot the server.

Is there any problem /risk with this approach? if yes, how does it impact?

Cheers
Salai
