Reachy Mini Wireless: Local Privilege Escalation via Unrestricted sudo systemctl Grant

Type: advisorySource: Official CVE List1 source record

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.
