A empresa ARM revelou informa\u00e7\u00f5es sobre tr\u00eas vulnerabilidades em drivers para suas GPUs, utilizadas em Android, ChromeOS e distribui\u00e7\u00f5es Linux. As vulnerabilidades permitem que um usu\u00e1rio local n\u00e3o privilegiado execute seu c\u00f3digo com privil\u00e9gios de kernel. No relat\u00f3rio de problemas de seguran\u00e7a da plataforma Android de outubro, menciona-se que, antes da corre\u00e7\u00e3o, uma das vulnerabilidades (CVE-2023-4211) j\u00e1 foi explorada por invasores em exploits ativos para realizar ataques direcionados (0-day). Por exemplo, a vulnerabilidade pode ser utilizada em aplicativos maliciosos distribu\u00eddos por fontes duvidosas para obter acesso total ao sistema e instalar componentes que espionam o usu\u00e1rio. <\/p>\n
Vulnerabilidades encontradas: <\/p>\n
A corre\u00e7\u00e3o tamb\u00e9m foi proposta como parte das atualiza\u00e7\u00f5es de setembro para os ramos do Chrome OS 114\/115\/116 e na atualiza\u00e7\u00e3o de outubro do Android. Os modelos vulner\u00e1veis de GPU s\u00e3o utilizados em smartphones como Google Pixel 7, Samsung S20 e S21, Motorola Edge 40, OnePlus Nord 2, Asus ROG Phone 6, Redmi Note 11, 12, Honor 70 Pro, RealMe GT, Xiaomi 12 Pro, Oppo Find X5 Pro, Reno 8 Pro e em alguns dispositivos com chips Mediatek. <\/p>\n
No total, o relat\u00f3rio de outubro sobre vulnerabilidades no Android menciona 53 vulnerabilidades, das quais 5 foram classificadas como cr\u00edticas, enquanto as demais foram classificadas como de alto risco. Problemas cr\u00edticos permitem ataques remotos para executar seu c\u00f3digo no sistema. Problemas marcados como perigosos permitem, atrav\u00e9s da manipula\u00e7\u00e3o de aplicativos locais, executar c\u00f3digo no contexto de um processo privilegiado. Tr\u00eas problemas cr\u00edticos (CVE-2023-24855, CVE-2023-28540 e CVE-2023-33028) foram identificados em componentes propriet\u00e1rios da Qualcomm e dois (CVE-2023-40129, CVE-2023-4863) no sistema (no libwebp e na pilha Bluetooth). No total, foram identificadas 5 vulnerabilidades nos componentes da ARM, 3 na MediaTek, 1 na Unisoc e 17 na Qualcomm (relat\u00f3rio da Qualcomm). Duas vulnerabilidades (uma na GPU ARM e uma no libwebp) foram marcadas como j\u00e1 sendo utilizadas por atacantes em seus exploits (0-day). \u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f ARM
