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.
