Description
In the Linux kernel, the following vulnerability has been resolved:
pseries/papr-hvpipe: Prevent kernel stack memory leak to userspace
The hdr variable is allocated on the stack and only hdr.version and
hdr.flags are initialized explicitly. Because the struct papr_hvpipe_hdr
contains reserved padding bytes (reserved[3] and reserved2[40]), these
could leak the uninitialized bytes to userspace after copy_to_user().
This patch fixes that by initializing the whole struct to 0.
