Detailsinfo

A vulnerability has been found in Linux Kernel up to 4.13.11 (Operating System) and classified as critical. This vulnerability affects some unknown processing of the file drivers/net/usb/asix_devices.c of the component USB Device Handler. The manipulation with an unknown input leads to a null pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

drivers/net/usb/asix_devices.c in the Linux kernel through 4.13.11 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device.

The bug was discovered 11/06/2017. The weakness was disclosed 11/07/2017 by Andrey Konovalov (Website). The advisory is shared for download at securityfocus.com. This vulnerability was named CVE-2017-16647. The attack needs to be approached locally. Required for exploitation is a single authentication. There are known technical details, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 104943 (Fedora 26 : kernel (2017-f9f3d80442)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 276998 (Fedora Security Update for kernel (FEDORA-2017-905bb449bc)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 4 weeks after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (104943) and SecurityFocus (BID 101767†). The entries VDB-109189, VDB-109190, VDB-109191 and VDB-110023 are pretty similar. Once again VulDB remains the best source for vulnerability data.
