It's not addiction. That makes in sound like self pat on the back disguised as a problem.

It's the equivalent of being neat freak. Some people are annoyed when they see breadcrumbs on the floor and feel a compelling urge to clean it. You experience a compelling urge to fix tech problems.

I think many people have that on various subjects.

It's not really a problem though. More an obsession than an addiction really. Being obsessive about your work is not a problem as long as you maintain proper live/work balance.
