Subject: CVE-2017-7874 versus CVE-2009-1185 ?


I stumbled across
that is curious about an udev+kernel exploit

which claims to exploit a missing sender-check within udev. That makes
me wonder, as kernel 4.8.0 (and even earlier) no longer allow users
to send NETLINK_KOBJECT_UEVENT messages. Our testcases fail,
as they should:

However, MITRE apparently assigned a valid CVE for it:

So either we miss some weird corner case or the CVE is invalid
and should be withdrawn?
