The oddjobd service exists to provide an interface and
access control mechanism through which
specified privileged tasks can run tasks for unprivileged client
applications. Communication with oddjobd through the system message bus.
The oddjobd service can be disabled with the following command:
$ sudo systemctl mask --now oddjobd.service
The oddjobd service may provide necessary functionality in some environments, and can be disabled if it is not needed. Execution of tasks by privileged programs, on behalf of unprivileged ones, has traditionally been a source of privilege escalation security issues.
