Root code execution via unauthenticated package installation
Published Jul 23, 2025 · Updated Apr 7, 2026
Local privilege escalation in Deepin Linux with lastore-daemon 0.9.53-1 and 0.9.66-1 allows local users to execute arbitrary code as root. The system D-Bus policy lets sudo-group callers invoke InstallPackage without password authentication, so the root daemon installs an attacker-built .deb and runs its post-install script. Exploitation requires shell access and sudo-group membership; the first account created by default has that membership.
