I’ll assume your sink has a trap.
It may be that the waste line’s vent is clogged and the trap (whose purpose is to retain a bit of water and block sewage gas from entering your home) is therefor being suctioned out. First try the baking soda/vinegar idea suggested above. if foul smells continue to come from the sink you may have a blocked vent. In all probability, that means a plumber will need to be called.
If the trap has a plug you can unscrew, you can easily check to see if it’s full of water (just don’t forget to position a bucket below it). If it doesn’t have a plug, wait until a smell is coming from the sink and then slowly pour a cup of water down the drain. If this stops the smell, you probably are having the trap suctioned out.
