Com 8.642 CVEs catalogadas e 248 confirmadas em exploração ativa pelo CISA KEV, a taxa de exploração do portfólio Microsoft está 6,4 vezes acima da média geral do catálogo, o que indica exposição operacional significativamente elevada em relação ao universo de vendors monitorados. O tipo de falha mais recorrente é CWE-416 (use-after-free), uma classe de vulnerabilidade com alto potencial de execução arbitrária de código e historicamente difícil de mitigar em escala. A CVE mais crítica atualmente em exploração ativa é CVE-2019-0708, com EPSS de 1,0 — o valor máximo da escala —, sinalizando probabilidade de exploração praticamente certa no curto prazo e exigindo atenção prioritária em ambientes onde a correção ainda não foi aplicada. Os 561 registros surgidos nos últimos 90 dias, combinados com 320 CVEs com prova de conceito pública, reforçam a necessidade de ciclos de patching contínuos e monitoramento ativo de exposição.
