CVE-2022-50030

Estado: AnalizadaAlta (7.8)—

In the Linux kernel, the following vulnerability has been resolved:

scsi: lpfc: Prevent buffer overflow crashes in debugfs with malformed user input

Malformed user input to debugfs results in buffer overflow crashes. Adapt input string lengths to fit within internal buffers, leaving space for NULL terminators.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector AV:L/PR:L sin UI indica escalada local. Buffer overflow (CWE-787) en debugfs del kernel lpfc permite ejecución de código con privilegios elevados desde contexto local con permisos limitados.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
