It's not just possible, but highly likely to occur in the near future. What if the company folds and there is a bug that causes it to halt and catch fire? What stops a RAM/ROM bit flipping?
Connected HSS is fundamentally a problem, not unlike IoT. I have several UPS's and not once did I think this might occur, because they are simply not attached to my network in any way. The triggers are based in hardware with a small microcontroller and are unlikely to fail.
Systems that run for long periods and could cause damage should be developed differently. Core safety features should be hardware-based, you shouldn't be able to hack it and make it do something dangerous. If it has to be network connected it should be defensively designed.
