CVE-2026-80696

Estado: RecibidaAlta (7.8)—

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

hwmon: (ltc4282) Fix reading the minimum alarm voltage

Coverity reports an out-of-bounds access when reading the minimum alarm voltage for the VGPIO channel. Add the missing return statement to fix the problem.

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 sin interacción (AV:L, PR:L, UI:N) en kernel Linux indica escalada de privilegios. Out-of-bounds access puede leer datos sensibles del 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.
