CVE-2018-19854

Estado: ModificadaMedia (4.7)—

Se ha descubierto un problema en el kernel de Linux hasta antes de la versión 4.19.3. crypto_report_one() y otras funciones relacionadas en crypto/crypto_user.c (la API de configuración de usuarios crypto) no inicializan completamente las estructuras que se copian en el espacio de usuario, lo que podría filtrar memoria sensible a los programas del usuario. NOTA: esta es una regresión de CVE-2013-2547, pero con una explotabilidad más sencilla. Esto se deba a que el atacante no necesita una capacidad (sin embargo, el sistema debe tener la opción de kconfig CONFIG_CRYPTO_USER).

CVSS

Probabilidad de explotación (EPSS)

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).
