    O seu carro autônomo pode ser o alvo de hackers? Conheça a CVE-2026-12191! A equipe de pesquisas Yokai da Hakai publicou uma pesquisa alarmante que destrincha uma vulnerabilidade crítica no openpilot, um ecossistema de assistência à direção adotado em mais de 275 modelos de veículos. A pesquisa revelou uma falha grave de desserialização insegura devido ao uso de um módulo inerentemente inseguro do Python, o pickle. Essa brecha permite que um atacante obtenha Execução Remota de Código (RCE) com privilégios de root no sistema. Qual o impacto real disso? Na prática, abre-se uma porta dos fundos que permite o controle físico completo do automóvel, incluindo freios, aceleração e direção, o que pode causar acidentes intencionais. Além disso, o invasor pode utilizar as câmeras, o microfone e o GPS do veículo para espionagem, ou até mesmo comprometer o canal de atualizações do fabricante em um ataque de Supply Chain, afetando simultaneamente dezenas de carros. E para mitigar esse cenário crítico é importante realizar a substituição do módulo pickle por formatos seguros. Leia o artigo completo "Build Your Nightmare" para entender a fundo a cadeia de ataque e ver como funciona a Prova de Conceito (PoC) em detalhes.
