CVE-2026-54467

Estado: AplazadaAlta (7)—

On the Trusted Firmware-M (TF-M) 2 through 2.3.0 platform before 00d1b3e, mailbox initialization on PSOC64 and RP2350 accepts a non-secure, unvalidated, supplied pointer.

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:P (acceso físico) → T1091. Pointer no validado en TF-M permite elevar privilegios (S:C) y leer datos confidenciales (C:H) en firmware de confianza.

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.
