It is interesting this one is listed in both CVE-145, CVE-147 in
cip-kernel-sec. Is that an error?

I see also

- i40e: Set RX_ONLY mode for unicast promiscuous on VLAN

which apparently allows people to listen to packets they should not
see. But I assume this requires elevated priviledges to begin with...

Best regards,
                                                                Pavel
