The following bits from the standard draft seem to support what you say:

[basic.compound].3 "The type of a pointer to void or a pointer to an object
type is called an object pointer type. [ Note: A pointer to void does not have
a pointer-to-object type, however, because void is not an object type. — end
note ]"

[expr.unary.op].1 "The unary * operator performs indirection: the expression to
which it is applied shall be a pointer to an object type, or a pointer to a
function type and the result is an lvalue referring to the object or function
to which the expression points."
