Unfortunately this is also a recipe of dropping an unpatched unmaintainable Linux machine on the network to provide interesting security challenges in the future.
Of course, my Buffalo NAS can’t compete with that and got fewer updates than my old phone…
It is no longer connected to an internet facing network.
Vendor kernels are a continual security apocalypse that never ends.
Using it for my router, firewall and NAS hardware - and can totally recommend it.
