Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1381191]

Comment 3 Vladis Dronov 2016-10-03 11:22:35 UTC

Statement:

This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5. 6, 7 and Red Hat Enterprise MRG-2 as the code with the flaw is not present in the products listed.

Comment 6 Justin M. Forbes 2016-10-03 13:32:56 UTC

This issue was resolved in the 4.7.1 stable update, and does not impact any currently supported fedora kernel.
