Description Martin Prpič 2015-10-23 13:01:07 UTC
An information leak flaw was found in Linux kernel for systems using Vivid! display drivers in framebuffer mode.  16 bytes of memory is not zeroed and may leak from userspace to a user at the console.

Comment 1 Martin Prpič 2015-10-23 13:03:52 UTC
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1274730]

Comment 2 Josh Boyer 2015-10-23 13:25:05 UTC
This requires CONFIG_VIDEO_VIVID to be enabled.  None of the Fedora kernels have this driver enabled.

Comment 4 Vladis Dronov 2016-01-26 13:54:38 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.
