CVE-2025-52568

Estado: AplazadaAlta (8.8)—

NeKernal is a free and open-source operating system stack. Prior to version 0.0.3, there are several memory safety issues that can lead to memory corruption, disk image corruption, denial of service, and potential code execution. These issues stem from unchecked memory operations, unsafe typecasting, and improper input validation. This issue has been patched in version 0.0.3.

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 CVSS AV:N/PR:N/UI:N indica explotación remota sin privilegios (T1190). VI:H/VA:H sugiere corrupción de memoria e integridad; los CWE-20 y CWE-770 (validación deficiente, agotamiento de recursos) con menciones explícitas a DoS y corrupción justifican T1499.004 y T1565.001.

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.
