Recent CMS heavy flavor physics results

In this paper, recent results in the B-physics field achieved using proton-proton collision data at $\sqrt{s}=8$ TeV and $13$ TeV collected by CMS are presented. They include the angular analysis of the decay $\mathrm{B^{+}}\to \mathrm{K}^{*+} \mu^{+} \mu^{-}$ with Run 1 data, new measurements of D and B mesons production cross sections and CP violation studies using ${B}_s^{0}$ decays with Run 2 data. The results are compared with the standard model predictions. A measurement of the $CP$ violating phase $\phi_{s}$ achieved by combining results from both Run 1 and Run 2 data is also presented.
