Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1746726]

Comment 2 Wade Mealing 2019-12-04 08:05:48 UTC
Note:

This flaw is classified in the attack vector (local) that the device appears to the kernel.  Local attacks would not be considered remote attacks if the attacker must first ssh in.  

Red Hat Enterprise Enterprise Linux does not ship a kernel with this network device enabled.
