CVE-2025-68303

Estado: AplazadaAlta (7.8)—

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

platform/x86: intel: punit_ipc: fix memory corruption

This passes the address of the pointer "&punit_ipcdev" when the intent was to pass the pointer itself "punit_ipcdev" (without the ampersand). This means that the:

in intel_punit_ioc() will write to a wrong memory address corrupting it.

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.

Corrupción de memoria en kernel de Linux por pase incorrecto de puntero (AV:L, PR:L, sin UI). El atacante local puede corromper memoria del kernel (T1565.001) o causar DoS (T1499.004).

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.
