The overall combination is presented of eight standard model (SM) Higgs boson searches performed by the CMS Collaboration using the following Higgs boson decay signatures: $H \to \gamma\gamma$, $H \to \tau\tau$, $H \to bb$, $H \to WW \to 2\ell 2\nu$, $H \to ZZ \to 4\ell$, $H \to ZZ \to 2\ell 2 \tau$, $H \to ZZ \to 2\ell 2\nu$, and $H \to ZZ \to 2\ell 2q$. Depending on the analysis, the amount of data used corresponds to 1.1-1.7~fb$^{-1}$ of integrated luminosity. The SM Higgs boson is excluded at 95\% C.L. in three mass ranges 145-216, 226-288, and 310-400~GeV/$c^2$. The expected exclusion in the absence of a signal is 130-440~GeV/$c^2$. The largest excursion of the observed data from the expected has a probability of 0.4 after taking into account the look-elsewhere effect. At 90\% C.L., we exclude the SM Higgs boson in the continuous mass range from 144-440~GeV/$c^2$. The reported limits were obtained using the modified frequentist construction known as the $\mathrm{CL_s}$ method.
