Só é mencionado nos filmes que eles o curaram enquanto ele dormia em Wakanda. No Captain America: The Civil War é claro que é afirmado que eles vão tentar curá-lo e depois no Pantera negra postar cena de créditos Bucky é visto morando em uma cabana da tribo da fronteira. Shuri sai para encontrá-lo e ele agradece a ela e ela vai "ensiná-lo". Eu acredito que isso é alusão a ela tê-lo curado.
Shuri: Good morning, Sergeant Barnes.
Bucky Barnes: Bucky.
Shuri: How are you feeling?
Bucky Barnes: Good. Thank you.
Shuri: Come. Much more for you to learn.
Black Panther
Até onde eu sei, não há nada mais explícito do que isso nos filmes, apenas T'Challa aludindo a isso dizendo "O lobo branco já descansou o suficiente" in Avengers: Infinity War. No entanto, se formos aos quadrinhos complementares, podemos ver Vingadores: Guerra Infinita - Prelúdio Parte 1 onde é afirmado que Shuri encontrou uma maneira de curá-lo. Nós não vemos explicitamente Shuri curá-lo, mas como ela descobriu como e depois o vemos antes e depois Guerra Infinita eventos adequados, faz sentido que ela faz.

Months later...
Shuri: ...I'm your best bet on this.
T'Challa: You say you've made a breakthrough?
Shuri: I said you needed to come and see what I've been doing so I can impress you with my genius.
T'Challa: You tell me what it is you've done and I'll decide whether or not to clap for you.
Shuri: Fine. But for you to fully appreciate, you should understand how hard it is to do what you asked of me.
Shuri: It's not as simple as erasing mental programming outright. There's no delete button here. And a majority of his programming is linked to trigger words.
Shuri: The last thing we want to do is remove all of who Sergeant Barnes is -- his loves, his hates, his quirks, his whole personality -- when trying to destroy what Hydra made him to be.
Shuri: The hardest part is rooting out the extent of his memories that have the greatest amount of control over his physical actions... the ones that have been manipulated due to their deep emotional trauma... [of which there are many].

T'Challa: I'm waiting for the part where you tell me the good news.
Shuri: I've been running an algorithm that will be able to flush the influence of the trigger words out while retaining the core context and content of those original memories. Essentially I should be able to reboot him.
Shuri: But more exciting is that this algorithm should provide even greater advancements in Wakanda's own artificial intelligence applications in the near future. It's so much simpler that that silly shortcut Tony Stark took in creating Ultron. Of course that's 'cause I'm smarter than him.
T'Challa: It sounds like you've put a lot of thought into telling me how smart you are, but I believe you are right.
T'Challa: At the very least, for now, Sergeant Barnes can dream in peace.
T'Challa: And I'm sure that would make Steve Rogers happy enough to hear...
