CVE-2025-37975

Estado: AnalizadaAlta (7.1)—

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

riscv: module: Fix out-of-bounds relocation access

The current code allows rel[j] to access one element past the end of the relocation section. Simplify to num_relocations which is equivalent to the existing size expression.

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:L/PR:L sin UI indica escalada local. Out-of-bounds en módulo kernel permite ejecución de código o DoS; C:H/A:H confirma impacto crítico de confidencialidad y disponibilidad.

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.
