Technical details
A local privilege escalation vulnerability exists in systemd-machined versions 259 through 259.2. The flaw is rooted in incorrect authorization (CWE-863) where Varlink IPC calls can be leveraged to reach the root namespace from an unprivileged context. To exploit this, an attacker must be an unprivileged user logged into a local desktop graphical session; remote sessions like SSH are reportedly unaffected. Successful exploitation allows the user to escalate privileges to root. The issue is addressed in systemd version 260 and backported to 259.3. A workaround involves implementing a Polkit rule to restrict 'org.freedesktop.machine1.register-machine' actions to administrative users.
