The AX.25 daemon (ax25d) in ax25-tools before 0.0.8-13 does not check the return value of a setuid call. The setuid call is responsible for dropping privileges but if the call fails the daemon would continue to run with root privileges which can allow possible privilege escalation.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
