CVE-2023-53432

Estado: ModificadaAlta (7.8)—

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

firewire: net: fix use after free in fwnet_finish_incoming_packet()

The netif_rx() function frees the skb so we can't dereference it to save the skb->len.

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.

Vulnerabilidad local (AV:L, PR:L) de uso después de liberación (CWE-416) en kernel Linux que permite escalada de privilegios. El atacante con acceso local puede ejecutar código con privilegios elevados explotando la referencia a memoria liberada en el controlador firewire.

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.
