There is an issue with the Tx interrupt processing in the MCAL CAN driver. In the function Can_mcanProcessISRTx() when calling CanIf_TxConfirmation(), the first argument is canMailbox->canTxRxPduId[messageBox] which points to the canTxRxPduId[messageBox] for HTH == 0.

This should be replaced by mailboxObj->canTxRxPduId[messageBox] where mailboxObj = &canMailbox[hth];

The HTH can be fixed in the top level for loop by comparing against objTxMbxType[loopCnt].hth;

Please refer the attached diff patch.
