In this paper, we consider a complete strongly stable hypersurface Mn with constant mean curvature (CMC) H in Nn+1(κ), where 2 ≤ n ≤ 5, and prove that Mn is totally umbilical if H2 + κ > 0 and the L2 norm curvature satisfies some growth conditions. In addition, we obtain that a complete stable hypersurface Mn in Nn+1(κ) (n = 3, 4, 5) with CMC is a geodesic sphere if − H2 < κ ≤ 0 and Mn has some finite Lp norm curvature.
