CVE-2025-5867

Estado: AnalizadaAlta (8.6)—

A vulnerability classified as critical was found in RT-Thread 5.1.0. This vulnerability affects the function csys_sendto of the file rt-thread/components/lwp/lwp_syscall.c. The manipulation of the argument to leads to null pointer dereference.

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.

AV:A (red adyacente), PR:L (requiere privilegios), sin UI:R → T1210. Null pointer en syscall de red (csys_sendto) permite ejecución de código con impacto VC:H (confidencialidad)/VI:H (integridad).

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.
