CVE-2026-53205

Estado: AnalizadaAlta (7.1)—

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

accel/ivpu: Add bounds checks for firmware log indices

Add validation that read and write indices in the firmware log buffer are within valid bounds (< data_size) before using them. If out-of-bounds indices are encountered (from firmware), clamp them to safe values instead of proceeding with invalid offsets.

This prevents potential out-of-bounds buffer access when firmware supplies invalid log indices.

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) del kernel Linux permite escalada de privilegios (I:N, A:H) explotando índices fuera de límites (CWE-787) en el driver accel/ivpu, potenciando ejecución arbitraria o DoS.

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.
