What is the difference between Moksha and Buddhist Enligthenment?

In Hinduism, as I understand it, Moksha is when you realize the true nature of reality (as either non-dual or partially dual, depending on the tradition) and are freed from Samsara (the cycle of death and rebirth, and the suffering that goes along with it) and become one with Brahman. How is this different from the Buddhist concept of reaching enlightenment, becoming a Buddha, and being freed from death and rebirth. Is Buddhism merely the concept of Moksha disentangled from the rest of Hinduism, or am I missing something here?
