Details

In the Linux kernel, the following vulnerability has been resolved:

nbd: always initialize struct msghdr completely

syzbot complains that msg->msggetinq value can be uninitialized [1]

struct msghdr got many new fields recently, we should always make sure their values is zero by default.
