On a whim I opened up the:
Legal Disclaimer Open Source Licenses
in the management page for my fiber modem (ATT installed 2021/03/30)
and discovered that the kernel is rather old:
linux kernel - Version 3.4.11
There are about 163 other open source components, probably most of
similar ages.
Is this a security problem?
I would not worry too much about it. All the equally old stuff in
userspace is a bigger concern.
On the other hand, my ISP already has complete control of my cable
modem; they apply firmware updates and manage the configuration. All
I can do is log in and view the status report. The modem is
effectively part of the ISP infrastructure, which is already beyond my
control.
My modem runs in bridge mode and I have a separate router to interface
with the LAN. This provides a clear demarcation between the ISP and
my LAN.
Kind of the same, except.
My public IPv4 and IPv6 space is between my ISP gear and my firewall.
So my public servers have to be there. Got them locked down as much as
I can.
I tried setting up one zone on my firewall in bridged mode, but I gave
up on that. I really need new firewall gear and need to try that again...
Everything else is behind my firewall.
