CVE-2026-31743

Estado: AnalizadaAlta (7.8)—

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

nvmem: zynqmp_nvmem: Fix buffer size in DMA and memcpy

Buffer size used in dma allocation and memcpy is wrong. It can lead to undersized DMA buffer access and possible memory corruption. use correct buffer size in dma_alloc_coherent and memcpy.

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.

Acceso local (AV:L) sin interacción (UI:N) con privilegios (PR:L). Corrupción de memoria por buffer undersizado (CWE-787) en DMA/memcpy permite escalada de privilegios y ejecución de código o manipulación de datos en 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.
