We don't know the story, if we ever will
We know the NCAA can be pretty ridiculous. This could be something bad, or it could be something relatively harmless. Knowing the NCAA, I wouldn't be surprised if it was closer to relatively harmless than anything.
Anyone know the background of his family? Does he come from money? I remember in the Fab Five documentary they were talking about Ed Martin, who was one of the big Michigan boosters, and some of the guys were saying stuff like "if you're poor and you don't have any good basketball shoes, and someone offers to buy you some, you're not gonna say no." This was more for younger kids, and I'm guessing UCLA is providing Shabazz with enough shoes, but I'm just saying. If a kid is poor and gets busted by the NCAA because someone was buying shoes or food for him, I'm going to feel bad for him even if he did technically break the rules. (Yes, we don't know if that is the case here)
