Morphology
The meaning is directly derivable from combining 'poison' (harmful substance) with 'oak' (a type of tree): a learner will infer it is an oak that is harmful/poisonous. Noun–noun compounds that name a harmful plant are cross-linguistically common, so a B1 learner who knows both constituents will generally understand that this refers to a poisonous/irritant plant (likely causing a rash).
Etymology
Poison oak also means the red, itchy 'skin irritation' you get after touching the plant, because the plant's oil acts like a 'poison' on the skin.
