CVE-2020-6616
Estado: ModificadaMedia (6.5)—
Algunos chips Broadcom manejan inapropiadamente la generación de números aleatorios de Bluetooth porque es usado un Pseudo Random Number Generator (PRNG) de baja entropía en situaciones en las que debería haberse utilizado un Hardware Random Number Generator (HRNG) para impedir la suplantación de identidad. Esto afecta, por ejemplo, a los dispositivos Samsung Galaxy S8, S8+ y Note8 con el chipset BCM4361. El ID de Samsung es SVE-2020-16882 (Mayo de 2020).
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
- Puntuación base: 6.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.73%
- Percentil entre todas las CVEs puntuadas: 53
- Fecha de la puntuación: 8/10/2026
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).
