Fields ->dev and ->next of struct ipddp_route may be copied to userspace on the SIOCFINDIPDDPRT ioctl. This is only accessible to CAP_NET_ADMIN though. Let's manually copy the relevant fields instead of using memcpy().

USB: hso: Fix OOB memory access in hso_probe/hso_get_config_data 2019-03-25T17:32:32+00:00 Hui Peng benquike@gmail.com 2018-12-12T11:42:24+00:00 2d955f32f4ab31294447a01cf401cec2cef9013e commit 5146f95df782b0ac61abde36567e718692725c89 upstream. The function hso_probe reads if_num from the USB device (as an u8) and uses it without a length check to index an array, resulting in an OOB memory read in hso_probe or hso_get_config_data. Add a length check for both locations and updated hso_probe to bail on error. This issue has been assigned CVE-2018-19985.
