Doesn't:
    https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
describe it well enough?

Hint, putting a "Fixes:" only tag on a patch is nice, but will not
guarantee it will end up in the stable tree.  Only a "Cc: stable@..."
tag will.  Putting both on, if you know the fixes commit, is the best.
