Análise Vexday

Com 1.477 CVEs catalogadas e 232 surgidas apenas nos últimos 90 dias, o volume de vulnerabilidades associadas ao Red Hat exige monitoramento contínuo. A taxa de exploração ativa está abaixo da média geral do catálogo, com apenas 1 CVE confirmada no CISA KEV — a CVE-2023-4911, que apresenta EPSS de 0,7861, indicando probabilidade elevada de exploração e merecendo atenção prioritária de equipes de resposta. Das 34 vulnerabilidades de severidade crítica, 18 contam com prova de conceito pública disponível, o que reduz a barreira técnica para exploração e aumenta o risco operacional. O tipo de falha mais recorrente é CWE-125 (leitura fora dos limites), padrão que frequentemente viabiliza vazamento de dados ou corrupção de memória e deve orientar revisões de hardening e priorização de patches.
