Here are results of testing exploits from https://github.com/jollheef/lpe with the LKRG by Openwall (https://www.openwall.com/lkrg/)
For unprepared (no code to bypass LKRG) exploits it actually works well. Only CVE-2016-5195 (aka Dirty COW) still works.
@dump_stack
Good to know. Actually everyone is looking for an exploit that would work under LKRG as you've probably seen on the mailing list :)
