CVE-2019-18660
Estado: ModificadaMedia (4.7)—
El kernel de Linux anterior a la versión 5.4.1 en powerpc permite la exposición de información porque la mitigación Spectre-RSB no está implementada para todas las CPU aplicables, también conocido como CID-39e72bf96f58. Esto está relacionado con arch / powerpc / kernel / entry_64.S y arch / powerpc / kernel / security.c.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N
- Puntuación base: 4.7
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.74%
- 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).
