Description :rtapi_app in linuxcnc-uspace in LinuxCNC before 2.9.9 allows privilege escalation. It is installed SUID root and loads shared library modules via dlopen() by using a user-supplied module name.

Because the process retains elevated privileges during module loading, this results in local privilege escalation to root.
