CVE-2022-50677

Estado: AplazadaAlta (7)—

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

ipmi: fix use after free in _ipmi_destroy_user()

The intf_free() function frees the "intf" pointer so we cannot dereference it again on the next line.

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.

Vulnerabilidad local (AV:L) con escalada de privilegios (C:H/I:H/A:H) en kernel Linux; use-after-free permite DoS o ejecución con permisos elevados.

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.
