We present an analysis of neutrino-driven magnetohydrodynamic (MHD) waves and instabilities in a rotating magnetoplasma with weak neutrino interactions. We show, for the first time, that neutrino-driven shear Alfv{ \'e}n and oblique magnetosonic waves can be coupled by the Coriolis force, forming new wave modes affected by this force, as well as neutrino beam and two neutrino flavor oscillations. Our work extends previous theories by demonstrating that shear Alfv{ \'e}n waves are influenced by neutrino effects and by identifying instabilities resulting from resonant interactions with both a streaming neutrino beam and flavor oscillations. We find that the Coriolis force, as well as plasma density and magnetic field strength, have a significant impact on the profiles of the instability growth rates. Our findings may shed new light on the physical mechanisms underlying core-collapse supernovae.
