We present recent measurements of multijet correlations using forward and low-pₜ jets performed by the CMS collaboration at the LHC collider. In pp collisions at √s = 7 TeV, azimuthal correlations in dijets separated in rapidity by up to 9.4 units were measured. The results are compared to BFKL- and DGLAP-based Monte Carlo generator and analytic predictions. In pp collisions at √s = 8 TeV, cross sections for jets with pₜ > 21 GeV and |y| < 4.7, and for track-jets with pₜ > 1 GeV (minijets) are presented. The minijet results are sensitive to the bound imposed by the total inelastic cross section, and are compared to various models for taming the growth of the 2 → 2 cross section at low pₜ.
