Desbordamiento de entero en la función mem_check_range en drivers/infiniband/sw/rxe/rxe_mr.c en el kernel de Linux en versiones anteriores a 4.9.10 permite a usuarios locales provocar una denegación de servicio (corrupción de memoria), obtener información sensible desde la memoria del kernel, o posiblemente tener otro impacto no especificado a través de una petición de escritura o lectura involucrando a la tecnología "RDMA protocol over infiniband" (también conocida como Soft RoCE).

CVSS

Puntuación base: 7.8
Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 1.15 %
Percentil entre todas las CVEs puntuadas: 67
Fecha de la puntuación: 20/10/2026

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).

Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
