Description
In the Linux kernel, the following vulnerability has been resolved:
net: can: j1939: Initialize unused data in j1939_send_one()
syzbot reported kernel-infoleak in raw_recvmsg() [1]. j1939_send_one()
creates full frame including unused data, but it doesn't initialize
it. This causes the kernel-infoleak issue. Fix this by initializing
unused data.
