Morphology
The meaning 'an oil that hardens or causes drying' is directly and compositionally derived from 'dry' (to remove moisture / to become dry) + 'oil' — the participial modifier 'drying' signals an oil that dries or is used for drying, the same pattern as 'cooking oil' or 'cleaning fluid'. This is a transparent, cross-linguistically common modifier+noun construction, so a B1 learner who knows the constituents would very likely infer the intended meaning.
Etymology
Drying oil gives a clear picture: drying means 'becoming hard' and oil is a liquid. Painters used these oils because they turn into a hard layer when they meet air, so the name means an oil that 'hardens' when it meets air.
