CVE-2026-53605

Estado: AplazadaAlta (7.8)—

Reachy Mini ISO for Wireless contains the necessary files to build a custom Raspberry Pi OS image for the Reachy Mini Wireless robot, using pi-gen. Prior to version 0.2.4, the Reachy Mini Wireless OS image shipped with an overly broad sudoers entry granting the pollen daemon user (uid 1000) passwordless sudo access to /usr/bin/systemctl with no subcommand or argument restriction. This is a local privilege escalation (LPE). Any process running as pollen can obtain full root (uid 0) on the device in three commands, with no additional vulnerability required and no user interaction. This issue has been patched in version 0.2.4.

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.

Escalada de privilegios local mediante entrada sudoers sobrepermisiva que permite al usuario pollen ejecutar systemctl sin restricciones, logrando acceso root sin interacción.

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.
