CVE-2023-53803

Estado: AplazadaAlta (8.1)—

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

scsi: ses: Fix slab-out-of-bounds in ses_enclosure_data_process()

A fix for:

Checking after (and before in next loop) addl_desc_ptr[1] is sufficient, we expect the size to be sanitized before first access to addl_desc_ptr[1]. Make sure we don't walk beyond end of page.

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 de red adyacente (AV:A) sin privilegios en kernel Linux; el slab-out-of-bounds puede causar DoS (A:H) o lecturas de memoria (C:H) si es explotado.

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.
