No PackageKit, uma camada D-Bus que unifica opera\u00e7\u00f5es de gerenciamento de pacotes, foi encontrada uma vulnerabilidade Pack2TheRoot (CVE-2026-41651), permitindo que um usu\u00e1rio n\u00e3o privilegiado instale ou remova um pacote arbitr\u00e1rio e obtenha acesso root ao sistema. O problema ocorre a partir da vers\u00e3o 1.0.2 (2014) e foi resolvido na vers\u00e3o 1.3.5 do PackageKit. <\/p>\n

Pesquisadores da Deutsche Telekom identificaram o problema utilizando o modelo de IA Claude Opus. Um exploit funcional foi preparado, atuando na maioria das distribui\u00e7\u00f5es com PackageKit, mas detalhes sobre a vulnerabilidade e seu exploit ser\u00e3o divulgados posteriormente para dar tempo aos usu\u00e1rios para atualizarem seus sistemas. A possibilidade de explora\u00e7\u00e3o da vulnerabilidade foi demonstrada no Ubuntu Desktop 18.04\/24.04.4\/26.04, Ubuntu Server 22.04 \u2014 24.04, Debian Desktop 13.4, RockyLinux Desktop 10.1 e Fedora 43 Desktop\/Server. O status da corre\u00e7\u00e3o das vulnerabilidades nas distribui\u00e7\u00f5es pode ser avaliado nas seguintes p\u00e1ginas (se a p\u00e1gina n\u00e3o estiver dispon\u00edvel, significa que os desenvolvedores da distribui\u00e7\u00e3o ainda n\u00e3o come\u00e7aram a considerar o problema): Debian, Ubuntu, SUSE, RHEL, Gentoo, Arch, Fedora, FreeBSD. <\/p>\n

A vulnerabilidade \u00e9 causada por uma condi\u00e7\u00e3o de corrida ao processar os flags de transa\u00e7\u00e3o no processo em segundo plano do PackageKit, permitindo que se mudem os par\u00e2metros da opera\u00e7\u00e3o entre a autoriza\u00e7\u00e3o e o in\u00edcio da opera\u00e7\u00e3o com o pacote. O atacante pode enviar uma solicita\u00e7\u00e3o D-Bus para executar uma opera\u00e7\u00e3o permitida a um usu\u00e1rio n\u00e3o privilegiado e, em seguida, enviar uma nova solicita\u00e7\u00e3o D-Bus. Se a solicita\u00e7\u00e3o repetida chegar antes do in\u00edcio real da opera\u00e7\u00e3o permitida, \u00e9 poss\u00edvel conseguir uma altera\u00e7\u00e3o dos flags da transa\u00e7\u00e3o j\u00e1 iniciada e mudar o estado em cache. <\/p>\n

Assim, a transa\u00e7\u00e3o permitida j\u00e1 iniciada ser\u00e1 executada com par\u00e2metros n\u00e3o originais, mas com par\u00e2metros alterados enviados na segunda solicita\u00e7\u00e3o. Alterando as informa\u00e7\u00f5es sobre o pacote a ser instalado, o atacante pode instalar qualquer outro pacote, incluindo um que ele tenha armazenado localmente. A instala\u00e7\u00e3o do pacote \u00e9 executada com permiss\u00f5es de root, portanto, para obter acesso root ao sistema, o atacante pode adicionar um script pr\u00f3prio ao pacote que ser\u00e1 executado automaticamente antes ou depois da instala\u00e7\u00e3o.
