Zeng Tao a18cd6c9b6 usb: core: fix slab-out-of-bounds Read in read_descriptors ... The USB device descriptor may get changed between two consecutive enumerations on the same device for some reason, such as DFU or malicius device. In that case, we may access the changing descriptor if we don't take the device lock here. The issue is reported: https://syzkaller.appspot.com/bug?id=901a0d9e6519ef8dc7acab25344bd287dd3c7be9 Cc: stable <stable@vger.kernel.org> Cc: Alan Stern <stern@rowland.harvard.edu> Reported-by: syzbot+256e56ddde8b8957eabd@syzkaller.appspotmail.com Fixes: 217a9081d8 ("USB: add all configs to the "descriptors" attribute") Signed-off-by: Zeng Tao <prime.zeng@hisilicon.com> Link: https://lore.kernel.org/r/1599201467-11000-1-git-send-email-prime.zeng@hisilicon.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2020-09-04 16:41:22 +02:00
