CVE-2026-23288

Estado: AnalizadaAlta (7.8)—

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

accel/amdxdna: Fix out-of-bounds memset in command slot handling

The remaining space in a command slot may be smaller than the size of the command header. Clearing the command header with memset() before verifying the available slot space can result in an out-of-bounds write and memory corruption.

Fix this by moving the memset() call after the size validation.

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.

AV:L, PR:L sin UI:R → escalada de privilegios (T1068). Out-of-bounds memset permite corrupción de memoria con code execution (T1059) e integridad de datos (T1565.001).

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.
