It is fairly common nowadays to run Linux as one task on an RTOS, and have other tasks manage the CAN controller and other devices that need a low latency response. Or, just to use a coprocessor for low-latency work, as is commonly done to manage wifi.

Routing gdb stub traffic through a hosted Linux to an RTOS task or coprocessor is not an elementary exercise, but is something an engineering student might be expected to implement, even as just part of the real project.
