CVE-2026-68219

Estado: RecibidaAlta (7.8)—

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

media: nxp: imx8-isi: Fix potential out-of-bounds issues

The maximum downscaling factor supported by ISI can be up to 16. Add minimum value constraint before applying the setting to hardware. Otherwise, the process will not respond even when Ctrl+C is executed.

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 limitados (PR:L) indica escalada local. El problema de bounds en ISI causa denial of service (proceso sin respuesta incluso con Ctrl+C).

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.
