CVE-2026-93225

Estado: RecibidaAlta (7.4)—

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

phy: fsl-imx8mq-usb: fix typec switch leak on probe error path

If probe fails after imx95_usb_phy_get_tca() succeeds, the typec switch leaks because the only cleanup path was in .remove(), which never runs on probe failure.

Use devm_add_action_or_reset() so the switch is cleaned up on both probe failure and driver removal. The imx95_usb_phy_put_tca() is no longer needed, it will be removed in .remove() too.

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 de gestión de recursos en kernel Linux que permite DoS por fuga de memoria en ruta de error de probe; requiere acceso local sin privilegios (AV:L/PR:N).

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.
