Comment 1 msiddiqu 2019-12-13 21:39:09 UTC
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1783548]

Comment 2 Justin M. Forbes 2019-12-16 17:18:30 UTC
This was fixed for Fedora with the 5.2.9 stable kernel update.

Comment 4 Wade Mealing 2019-12-20 04:44:19 UTC
This flaw is rated as moderate, its an information leak that only happens once at device creation time, access methods of the information is quite difficult.
