Description

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
