Boa tarde pessoal,Eu tenho que validar todos os kernel e se são vulneráveis ao Dirtycow. Caso sim ! Geral um relatório em xls. Para a RHEL eu já tenho o script que eles disponibilizaram (abaixo), porém gostaria de implementar outras versões neste mesmo script e gerar o relatório. Algum tem alguma ideia de como fazer isso ? No final do script eu coloco alguns kernel que não são vulneráveis para a debian e ubunto, porém me perco na hora de fazer essa comparação e implementar.
