CVE-2024-50071

Estado: ModificadaAlta (7.8)—

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

pinctrl: nuvoton: fix a double free in ma35_pinctrl_dt_node_to_map_func()

'new_map' is allocated using devm_* which takes care of freeing the allocated data on device removal, call to

double frees the map as pinconf_generic_dt_free_map() calls pinctrl_utils_free_map().

Fix this by using kcalloc() instead of auto-managed devm_kcalloc().

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 de doble liberación (CWE-415) en kernel Linux con acceso local (AV:L) y privilegios requeridos (PR:L). La escalada a ejecución de código ocurre tras corromper la memoria del kernel.

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.
