Vexday analysis

Com 12.630 CVEs catalogadas e 1.872 novas entradas nos últimos 90 dias, o Linux apresenta um volume de vulnerabilidades consistente com sua ampla base de código e adoção global. A taxa de exploração ativa — apenas 9 entradas no CISA KEV, representando 0,07% do total — está abaixo da média geral do catálogo (0,45%), o que sugere que, apesar da superfície de ataque extensa, a conversão de vulnerabilidades em ameaças ativas e confirmadas permanece relativamente contida. Ainda assim, a CVE-2026-31431 merece atenção prioritária: com EPSS de 0,9678, a probabilidade de exploração ativa é elevada, e seu status no KEV indica que esse risco já se concretizou. A falha mais comum — CWE-476 (desreferência de ponteiro nulo) — é representativa da complexidade inerente ao desenvolvimento em nível de kernel e reforça a necessidade de triagem contínua, especialmente diante das 23 vulnerabilidades com PoC pública disponível.
