CVE-2026-72065

Estado: RecibidaCrítica (9.8)—

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

net: mana: Validate the packet length reported by the NIC

Validate the packet length reported in the RX CQE before passing it to skb processing. The CQE is supplied by the NIC device and should not be blindly trusted.

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 de red sin autenticación (AV:N, PR:N, UI:N) en controlador NIC Linux que permite RCE al no validar longitud de paquete CQE; impactos: ejecución de código y DoS remoto sin privilegios previos.

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.
