Description Martin Prpič 2015-10-23 09:01:07 EDT

Upstream patch:

Comment 1 Martin Prpič 2015-10-23 09:03:52 EDT
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1274730]
Comment 2 Josh Boyer 2015-10-23 09:25:05 EDT
This requires CONFIG_VIDEO_VIVID to be enabled.  None of the Fedora kernels have this driver enabled.
Comment 4 Vladis Dronov 2016-01-26 08:54:38 EST

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.
