O maior problema não é o uso de kernels antigos em desktops... isso raramente será um problema muito grande.
Falhas como essa são um perigo em sistemas cujos administradores são relapsos e acham que nunca um usuáriozinho terá acesso ao sistema. Se pelo menos uma vez um mal intencionado conseguir acesso a uma conta, já era...
Isso é um grande alerta. Apesar da falha ser antiga, e talvez ter sido corrigida, muitos servidores ainda devem estar usando um kernel antigo e possivelmente com essa falha.
