https://notcve.org/view.php?id=CVE-2024-42076
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.
