Sasuke not telling about the CM to naruto is quite simple. He didn't want to worry him. As Hokage,Naruto alot in his head. and to add this CM, would make everything much worse. Like Naruto's previous encounter with CM was with Sasuke, his best and first friend, which he considered as his own brother was leaving the village. the CM having a big role in it. and now his son has it. which also came from a guy who seems more creepier than Orochimaru(imo). And sasuke seems to have already enough experience with the CM and has connections with guys like orochimaru and he travelled alot so he can probavly find a solution for it.

@Lorenzo. I don't think Naruto's SPSM has the ability to know everything. Since he did not know of momo or his rinnegen ability. it was more or less the reason naruto was able to learn all the other basic natures and mix biju chakra and their natures so easily.
