/* Intel Network Adapter Diagnostic Driver IOCTL Handling Vulnerability Vendor: Intel Product webpage: http://www.intel.com Affected product(s): Network Adapter Driver for Windows XP Network Adapter Driver for Windows 7 Network Adapter Driver for Windows 8 Network Adapter Driver for Windows 2008/R2 Network Adapter Driver for Windows 2012/R2 Affected version(s): Intel(R) iQVW64.SYS v1.03.0.7 Intel(R) iQVW32.SYS v1.03.0.7 Tested Operating systems: Windows XP SP3 (32-bit) Windows 7 SP1 (32/64-bit) Date: 14/03/2015 Credits: Glafkos Charalambous CVE: CVE-2015-2291 Disclosure Timeline: 10-06-2014: Vendor Notification 21-06-2014: Vendor Response/Feedback 08-08-2014: Vendor Response/Feedback 26-08-2014: Requesting Status/No Vendor Response 30-09-2014: Requesting Status/No Vendor Response 22-10-2014: Requesting Status/No Vendor Response 10-01-2015: Requesting Status/No Vendor Response 15-01-2015: Requesting Status/No Vendor Response 14-03-2015: CVE Requested 14-03-2015: CVE Assigned 14-03-2015: Public Disclosure Description: A vulnerability in iqvw32.sys and iqvw64e.sys drivers has been discovered in Intel Network Adapter Driver. The vulnerability exists due to insuffiecient input buffer validation when the driver processes IOCTL codes 0x80862013, 0x8086200B, 0x8086200F, 0x80862007 using METHOD_NEITHER and due to insecure permissions allowing everyone read and write access to privileged use only functionality. Attackers can exploit this issue to cause a Denial of Service or possibly execute arbitrary code in kernel space.
