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. Join the discussion | GCVE Database | 05/28/2026, 10:16:00 UTC Added: 07/17/2026, 10:20:07 UTC |
