CVE-2026-53605: CWE-250: Execution with Unnecessary Privileges in pollen-robotics reachy-mini-os
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.
AI Analysis
Technical Summary
The Reachy Mini Wireless OS image versions before 0.2.4 include an overly broad sudoers entry that grants the pollen daemon user (uid 1000) passwordless sudo access to /usr/bin/systemctl with no subcommand or argument restrictions. This misconfiguration allows local users with pollen privileges to escalate to root privileges without additional vulnerabilities or user interaction. The vulnerability is classified as CWE-250 (Execution with Unnecessary Privileges) and CWE-269 (Improper Privilege Management). It has a CVSS v3.1 score of 7.8, indicating high severity. The issue was patched in version 0.2.4.
Potential Impact
Any local process running as the pollen user can escalate privileges to root by exploiting unrestricted sudo access to systemctl. This results in full system compromise with high confidentiality, integrity, and availability impact. No additional vulnerabilities or user interaction are required for exploitation.
Mitigation Recommendations
Upgrade Reachy Mini OS to version 0.2.4 or later, where the overly broad sudoers entry has been corrected. This patch removes the unrestricted passwordless sudo access for the pollen daemon user, mitigating the local privilege escalation risk.
