Catalyzed big bang nucleosynthesis (CBBN) can lead to overproduction of 6Li in gravitino dark matter scenarios in which the lighter stau is the lightest standard model superpartner. Based on a treatment using the state-of-the-art result for the catalyzed 6Li production cross section, we update the resulting constraint within the framework of the constrained minimal supersymmetric standard model (CMSSM). We confront our numerical findings with recently derived limits on the gaugino mass parameter m1/2 and the reheating temperature TR.
