CVE-2024-57910

Estado: ModificadaAlta (7.1)—

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

iio: light: vcnl4035: fix information leak in triggered buffer

The 'buffer' local array is used to push data to userspace from a triggered buffer, but it does not set an initial value for the single data element, which is an u16 aligned to 8 bytes. That leaves at least 4 bytes uninitialized even after writing an integer value with regmap_read().

Initialize the array to zero before using it to avoid pushing uninitialized information to userspace.

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) con privilegios L (PR:L) sin interacción permite lectura de memoria no inicializada del kernel, filtrando información sensible a userspace.

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.
