The overall combination is presented of six standard model (SM) Higgs boson searches performed by the CMS Collaboration using the following Higgs boson decay signatures: $H \to \gamma\gamma$, $H \to \tau\tau$, $H \to WW \to 2\ell 2\nu$, $H \to ZZ \to 4\ell$, $H \to ZZ \to 2\ell 2\nu$, and $H \to ZZ \to 2\ell 2q$. Depending on the analysis, the amount of data used corresponds to 1.0-1.1~fb$^{-1}$ of integrated luminosity. The conclusion of this combination is that the SM Higgs boson is excluded at 95\% C.L. in two mass ranges 149-206 and 300-440~GeV/$c^2$, as well as several narrower intervals in between. The expected exclusion in the absence of a signal is 127-420~GeV/$c^2$. At 90\% C.L., we exclude the SM Higgs boson in the mass range from 145-480~GeV/$c^2$. The same experimental search results, reinterpreted in the context of the standard model with 4 fermion generations (SM4), allow us to exclude the SM4 Higgs boson with a mass in the range 120-600 GeV/$c^2$ at 95\% C.L.
