A picture might help a little more, but sores on the lips of cats are pretty common, and can be caused by many things, including dental disease, rodent ulcer (see article below), autoimmune disease, cancer, etc. To know for sure, your cat needs to be examined by a vet and a sample of the lesion examined under a microscope (either by a needle sample or a biopsy). https://www.petcoach.co/cat/condition/eosinophilic-disease/
