If a credit card transaction appears on your account, that you did not authorize, does it have to be fraud or could it be a glitch? For example, could the magnetic strip on someone else's card be corrupted somehow and going to the wrong account?

Its is extremely unlikely for this to occur by accident.
If a magnetic stripe becomes corrupted then the checksum on it will let the machine know and not perform the transaction.
So this would require both the data to become corrupted and the internal checksum to be corrupted in such a manner that everything adds up.
