Subject: usb: misc: iowarrior: fix information leak to userland
From: Vasiliy Kulikov <[email protected]>
commit eca67aaeebd6e5d22b0d991af1dd0424dc703bfb upstream.
Structure iowarrior_info is copied to userland with padding byted
between "serial" and "revision" fields uninitialized. It leads to
leaking of contents of kernel stack memory.
