Subject: Corrupted 'off' flag

Seeing these periodically:

Nov 17 11:25:18 curie kernel: [p_lkrg] <Exploit Detection> ON
process[25086 | last] has corrupted 'off' flag!

Nov 17 11:25:18 curie kernel: [p_lkrg] <Exploit Detection> Trying to
kill process[last | 25086]!

I suspect this is the `last` command is being run periodically by Wazuh.
When run as root from command line LKRG doesn't kick in. No harm done
otherwise, so just reporting this as a minor annoyance.


Linux curie 5.4.0-54-generic #60-Ubuntu SMP Fri Nov 6 10:37:59 UTC 2020
x86_64 x86_64 x86_64 GNU/Linux

LKRG is the latest git branch pulled & compiled yesterday.
