The NA48/2 and NA62 experiments at CERN have collected large samples of charged kaons decays in 2003-2004 and in 2007-2008, respectively. In this paper some recent results will be reported. A preliminary measurement by NA48/2 and by NA62 of the K±→π±γγ branching ratio is quoted, an analysis by NA62 of K+→e+νγ(SD+) is shown, a first evidence of the K±→π±π0e+e- decay by NA48/2 is reported. New measurements of Kl3 form factors are presented and finally the branching ratio of Ke4 decays is shown. All the results are preliminary. [ABSTRACT FROM AUTHOR]
