Vulnerabilidades en Lenovo
394 resultadosAnálisis Vexday
Com 369 CVEs catalogadas, o portfólio de vulnerabilidades da Lenovo apresenta taxa de exploração ativa abaixo da média geral do catálogo KEV, sem registros confirmados de exploração em curso. O tipo de falha mais frequente é CWE-20 (validação inadequada de entrada), o que sugere atenção recorrente à sanitização de dados em componentes de firmware e software proprietário. A CVE mais perigosa identificada atualmente é CVE-2022-3699, com score EPSS de 0,0428 — o maior valor observado no conjunto —, indicando probabilidade de exploração ainda relativamente baixa, mas suficiente para justificar priorização em ambientes corporativos que dependem de hardware Lenovo. As 13 vulnerabilidades surgidas nos últimos 90 dias e a presença de 4 falhas críticas reforçam a necessidade de ciclos regulares de atualização de firmware e drivers.
