Linux kernel is vulnerable to double free. The vulnerability exists in usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c
because is no need to call dev_kfree_skb() when usb_submit_urb() fails because can_put_echo_skb() deletes original skb and can_free_echo_skb() deletes the cloned skb causing a double free.
