Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1492641]

Comment 2 Vladis Dronov 2017-10-06 09:03:11 UTC
this is not a security flaw, so closing this bz as not-a-security-bug. fixing this as a regular bugfix is handled in bz1491465.

Comment 3 Justin M. Forbes 2018-01-29 16:46:40 UTC
This was fixed for Fedora with the 4.13 rebases.
