From 7cb5ee0e7e734969b39370ac739d473e0ae367bd Mon Sep 17 00:00:00 2001 From: Scott Bauer Date: Thu, 23 Jun 2016 08:59:47 -0600 Subject: [PATCH] HID: hiddev: validate num_values for HIDIOCGUSAGES, HIDIOCSUSAGES commands commit 93a2001bdfd5376c3dc2158653034c20392d15c5 upstream. This patch validates the num_values parameter from userland during the HIDIOCGUSAGES and HIDIOCSUSAGES commands. Previously, if the report id was set to HID_REPORT_ID_UNKNOWN, we would fail to validate the num_values parameter leading to a heap overflow.
