'How to upgrade to newer version of tool in Buildroot?

I am new to Buildroot and I am trying to figure out how to update genimage to newer version in Buildroot. I am currently on version 14 and I would like to update to version 15 of genimage tool.

Can anyone please let me know how to upgrade to newer versions of tools in Buildroot?

I found the PATCH file to bump to version 15 here : genimage But I am not sure how to apply this Patch file in Buildroot.

Thanks in advance.

P.S: I am using Buildroot 2021.11.2.
