CVE-2025-71075

Estado: ModificadaAlta (7.8)—

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

scsi: aic94xx: fix use-after-free in device removal path

The asd_pci_remove() function fails to synchronize with pending tasklets before freeing the asd_ha structure, leading to a potential use-after-free vulnerability.

When a device removal is triggered (via hot-unplug or module unload), race condition can occur.

The fix adds tasklet_kill() before freeing the asd_ha structure, ensuring all scheduled tasklets complete before cleanup proceeds.

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:N indica escalada local. Use-after-free en kernel permite ejecución arbitraria de código con privilegios elevados tras sincronización de tasklets.

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.
