Possibly damp plasterwork or there could be efflorescence on the underlying brickwork.
Strip the damaged paint away by lightly sanding back to bare plaster, going wider than the affected area. Then seal with a mist coat of paint, (1 part paint to 3 parts water), allow to dry thoroughly and apply a second mist coat of you desire. This will prevent the top coat from being absorbed to quickly before it dries.

Directly opposite a cooker is a very likely place for greasy deposits.
