‘Rogue’ hammer loses control and smashes carpenter’s thumb.

It's more like 'rogue' industrial robot arm loses control and smashes operator's skull. (There's a reason those robots have hazard markings and physical shutdown switches).

It would not be that strange to call a piece of mobile machinery that was out of control "rogue".

Probably a worse choice than simply calling it out of control, but not that strange.
