Comment 1 Martin Prpič 2015-10-23 13:04:54 UTC

Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1274730]

Comment 2 Josh Boyer 2015-10-23 13:22:03 UTC

This is in a staging driver.  It requires CONFIG_DGNC to be enabled.  Fedora doesn't enable staging drivers with a very few exceptions.  You might was well close this bug.

Comment 4 Vladis Dronov 2016-01-18 15:26:46 UTC

Statement:

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