No conjunto de corre\u00e7\u00f5es de setembro para problemas de seguran\u00e7a do Android, 49 vulnerabilidades foram corrigidas, das quais quatro foram classificadas como cr\u00edticas. Duas vulnerabilidades cr\u00edticas foram corrigidas no framework multim\u00eddia que permitem executar c\u00f3digo ao processar dados multim\u00eddia especialmente formatados. 31 vulnerabilidades foram corrigidas nos componentes para chips Qualcomm, das quais duas foram classificadas como cr\u00edticas, permitindo a realiza\u00e7\u00e3o de um ataque remoto. Os outros problemas s\u00e3o considerados perigosos, ou seja, permitem que, por meio de manipula\u00e7\u00f5es com aplicativos locais, c\u00f3digo seja executado no contexto de um processo
