We find that for a large enough strange quark mass, ms2/4\ensuremathμ\ensuremathΔ>2/3(1\ensuremath-0.023) (\ensuremathμ is the quark number chemical potential, \ensuremathΔ is the superconducting gap), the kaon condensed color flavor locked (CFL) phase of asymptotically dense strongly interacting 3 flavor quark matter is unstable with respect to spontaneous generation of currents of Nambu Goldstone bosons due to spontaneous breaking of baryon number symmetry and hypercharge symmetry in the CFLK0 ground state. The total baryon and hypercharge currents vanish in the ground state. We find that CFLK0 and the new state are separated by a first order phase transition. The result is derived in the mean field approximation of high density effective theory with electromagnetic interactions turned off.
