Análisis Vexday

O portfólio de vulnerabilidades da AMD reúne 443 CVEs catalogadas, com 59 registros surgidos nos últimos 90 dias, indicando um ritmo de descoberta que merece acompanhamento contínuo. A taxa de exploração ativa está abaixo da média geral do catálogo, com zero entradas no CISA KEV, o que sugere pressão operacional imediata menor em comparação com outros fornecedores. No entanto, a CVE mais perigosa atualmente monitorada, CVE-2023-20588, apresenta o maior EPSS observado no conjunto (0,1241), sinalizando probabilidade não negligenciável de exploração e justificando priorização nas rotinas de patch. A falha mais frequente, CWE-20 (validação inadequada de entrada), reflete uma fragilidade estrutural recorrente no código, enquanto as 6 CVEs de severidade crítica e a existência de pelo menos uma prova de conceito pública reforçam a necessidade de gestão ativa mesmo sem exploração confirmada no momento.
