Please feel free to submit these as tested patches that you know work to
these trees.

Here's an example of why this is not in the 5.15.y tree, it does not
apply at all.  How did you come up with this very small list of CVEs
when there are thousands of "missing" fixes in these older trees?

Have you tested this commit to verify it does work properly in the
5.15.y tree?

Again, if you wish to see these all applied, please submit the patches
that you have backported.

thanks,
