We consider a two-dimensional electron system with Coulomb interaction between particles at a finite temperature $T$. The Kohn singularity in the response function leads to a linear- in-$T$ correction to the quasiparticle $g$-factor and the spin susceptibility. We show that the universal linear temperature correction is a generic property of a strongly interacting electron system.
