We know combustion needs oxygen. But why is...

...the sun burning in vacuum outer space where there's a lack of it.

The sun is not burring Oxygen. The sun is a very large nuclear reactor fusing Hydrogen together to form Helium. Heat and Light are then produced.

The sun is not relying on oxygen to fuel it's energy. The sun is mostly hydrogen. The hydrogen is being fused together to make large amounts of energy, which makes more hydrogen atoms to fuse and make more energy.

Sun doesn't generate energy by cumbustion. It generates energy by a nuclear reaction known nuclear fusion. In this process two hydrogen atoms merge and create helium during this huge amount of energy is generated.So only fuel needed is hydrogen which is plenty on Sun.
