CVE-2018-1992
Estado: ModificadaMedia (6.4)—
El bootloader del firmware de arranque de IBM Power 9 OP910, OP920 y FW910 es responsable de cargar y validar la imagen de firmware de arranque inicial que inicializa el resto del hardware del sistema. El firmware del bootloader contiene una vulnerabilidad de desbordamiento de búfer por la que, si un atacante pudiese reemplazar la imagen de firmware de arranque inicial por un reemplazo cuidadosamente manipulado y lo suficientemente grande, podría provocar que el bootloader sobrescriba su propia memoria de instrucción durante la carga de dicha imagen y omita las protecciones de arranque seguras, instale troyanos, etc. IBM X-Force ID: 154345.
CVSS
- Versión: 3.0
- Vector: CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 6.4
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.35%
- Percentil entre todas las CVEs puntuadas: 27
- Fecha de la puntuación: 10/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
