We present our results of the local linear stability analysis of rotating jets confined by toroidal magnetic field. We apply the thin flux tube approximation and derive the equation of motion for slender flux tubes. In addition to the terms responsible for the conventional kink instability a term related to the buoyancy force and a term corresponding to the differential rotation become relevant for the stability properties. We find that the rigid rotation stabilizes while the differential rotational destabilizes the jet in a way similar to the Balbus Hawley instability. We show that if the azimuthal velocity is of the order of the Alfven azimuthal speed, the rigidly rotating part of the jet interior can be completely stabilized, while the strong shearing instability operates in the transition layer between the rotating jet interior and the external medium.
