This is not handled by software at all, but by the on-chip CAN controller hardware. You will not be able to add things like stuffing or CRC errors with software alone, though it can be achieved by various hardware tricks. One easy way to generate a whole lot of errors is to only have one node on the bus, or to short CAN …

WebCRC: The Cyclic Redundancy Check (CRC) is 15 bit in the Classical CAN, while in CAN FD it's 17 bits (for up to 16 data bytes) or 21 bits (for 20-64 data bytes). In Classical CAN, there can be 0 to 3 stuff bits in the CRC, while in CAN FD there are always four fixed stuff bits to improve communication reliability.
