Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 4.4/4.14.7 (Operating System). Affected is an unknown functionality of the component vhci_hcd driver. The manipulation with an unknown input leads to a information disclosure vulnerability (Kernel Memory). CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes:

The vhci_hcd driver in the Linux Kernel before version 4.14.8 and 4.4.114 allows allows local attackers to disclose kernel memory addresses. Successful exploitation requires that a USB device is attached over IP.

The bug was discovered 12/11/2017. The weakness was published 01/31/2018 by Jakub Jirasek with Secunia Research (Website). The advisory is shared for download at securityfocus.com. This vulnerability is traded as CVE-2017-16911 since 11/21/2017. The attack needs to be approached locally. The successful exploitation needs a authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1592.

The vulnerability was handled as a non-public zero-day exploit for at least 51 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 108748 (SUSE SLES12 Security Update : kernel (SUSE-SU-2018:0848-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 351263 (Amazon Linux Security Advisory for kernel: ALAC2012-2018-002).
