Very likely a case of anthracnose, a catch-all term for several different fungal pathogens that result in an assortment of leaf spots and early leaf drop. These tend to be highly weather related and high heat, high humidity and heavy rains can all contribute to the cause. But they are generally considered to be mostly cosmetic and seldom do any significant damage to an established tree. Control or a specific treatment is generally not warranted. Just clean up and dispose of ALL the fallen leaves to prevent spreading or overwintering the fungal spores on your property. And while probably not necessary, you can use a dormant oil spray in winter to smother any spores thay may be lurking on any stems or branches.
