CAN bus wiring has a big effect on how fast data can go on CAN. CAN bits are normally 2000ns (2 microseconds, or 500kbit/sec) or longer for slower buses (a J1939 CAN bus runs at 250kbit/sec and can be up to 40m long). But CAN FD has the promise of much faster speeds on conventional CAN bus wiring, up to 8Mbit/sec (i.e. 125ns bit times). Yet most of the automotive industry is using CAN FD at just 2Mbit/sec or even slower. Why is this?

There is a unique kind of satisfaction that comes with sitting in the cab of a fully loaded Class 8 tractor-trailer, turning the ignition key, and hearing a massive diesel engine roar perfectly to life. If you are the person who diagnosed the complex electrical fault, tore down the top end, or tracked down a ghost in the J1939 ECU network, that sound is pure validation.

An issue was discovered in Open-SAE-J1939 thru commit b6caf884df46435e539b1ecbf92b6c29b345bdfe (2025-11-30) in SAE_J1939_Read_Binary_Data_Transfer_DM16 causing a denial of service via crafted CAN frame on the J1939 bus.

collin80/Open-SAE-J1939 thru commit 744024d4306bc387857dfce439558336806acb06 (2023-03-08) contains an integer underflow leading to out-of-bounds write in Transport Protocol Data Transfer handling. At line 23: uint8_t index = data[0] - 1. When data[0] (sequence number from CAN frame) is 0, index underflows to 255. Subsequent write at tp_dt->data[255*7 + i-1] reaches offset 1791, …

Integer underflow vulnerability in Open-SAE-J1939 thru commit b6caf884df46435e539b1ecbf92b6c29b345bdfe (2025-11-30) in SAE_J1939_Read_Transport_Protocol_Data_Transfer,allows attackers to write to arbitrary memory via crafted sequence number from the CAN frame.
