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().</p> <p>This patch fixes that by initializing the whole struct to 0.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>pseries/papr-hvpipe: Prevent kernel stack memory leak to userspace</p> <p>The hdr variable is allocated on the stack and only hdr.version and hdr.flags are initialized explicitly.
