CVE-2026-76747

Estado: Pendiente de análisisCrítica (9.1)—

Buffer overflow vulnerabilities exist in the affected interface of AOS-S. Successful exploitation could allow an unauthenticated remote attacker to expose sensitive memory contents and cause a denial of service on the device.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H
Puntuación base: 9.1

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.45%
Percentil entre todas las CVEs puntuadas: 37
Fecha de la puntuación: 7/10/2026

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).
