Estado: AnalizadaAlta (7.8)—

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

media: rockchip: rkcif: fix off by one bugs

Change these comparisons from > vs >= to avoid accessing one element beyond the end of the arrays. While at it, use ARRAY_SIZE instead of the _MAX enum values.

[fix cosmetic issues]

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. Off-by-one en arrays de kernel permite ejecución de código o DoS. CWE-193 típicamente produce corrupción de memoria.

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.
