CVE-2026-53386

Estado: AnalizadaAlta (7.8)—

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

iio: adc: ti-ads1298: add bounds check to pga_settings index

ads1298_pga_settings has 7 elements but ADS1298_MASK_CH_PGA can yield values 0-7. If it yields a value >= 7, this causes an out-of-bounds array access. Add a bounds check and return -EINVAL if the index is out of range.

Note that the remaining value b111 is reserved so should not be seen in a correctly functioning system.

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 de usuario permite escalada a través de lectura fuera de límites en el kernel. El desbordamiento puede causar denegación de servicio o lectura de memoria 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.
