in both cases KERNEXEC catches the code execution attempts, but by that
time the exploit corrupted certain kernel memory and will destabilize
the system, even eryx (just run it enough times if you don't mind and
can risk a crash/reboot). there's nothing that can be done about it,
you must patch the bug as soon as possible.
