Subject: strange execmem
Date: Tue, 26 Feb 2019 09:40:44 +1100 [thread overview]
Message-ID: <2945607.tWFyTVdlCF@liv> (raw)
I'm seeing strange audit messages like the following from cron jobs on a
couple of systems. Any idea what this might be about? I don't expect grep to
be needing execmem access and when I run a command matching the proctitle at
the shell prompt it doesn't need it.
type=PROCTITLE msg=audit(26/02/19 00:00:07.426:1130782) : proctitle=grep -m 1
