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?
Yes, for such a old device, the vendor may have stopped receiving
vulnerable reports or publishing updates. And you device is connected
to network, that make things worse.

Usually, a botnet is made up of those unmaintained but still running
device.

I happened to have read a article about a botnet build on hacked modems
in China, https://blog.netlab.360.com/pink-en/ in this case, when
devices gets hacked, the only to "fix" is a replacement.

And try and get your FIber ISP to provide you with new gear.  I cannot replace it with my own.  Must use what they provide...
