Description		In the Linux kernel, the following vulnerability has been resolved: can: j1939: j1939_send_one(): fix missing CAN header initialization The read access to struct canxl_frame::len inside of a j1939 created skbuff revealed a missing initialization of reserved and later filled elements in struct can_frame. This patch initializes the 8 byte CAN header with zero.
