Linux Kernel up to 4.14.7 stub_tx.c stub_send_ret_submit null pointer dereference

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel up to 4.14.7 (Operating System). This affects the function stub_send_ret_submit of the file drivers/usb/usbip/stub_tx.c. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as 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. This is going to have an impact on availability. The summary by CVE is:

The "stub_send_ret_submit()" function (drivers/usb/usbip/stub_tx.c) in the Linux Kernel before version 4.14.8, 4.9.71, 4.1.49, and 4.4.107 allows attackers to cause a denial of service (NULL pointer dereference) via a specially crafted USB over IP packet.

The bug was discovered 12/11/2017. The weakness was presented 01/31/2018 by Jakub Jirasek with Secunia Research (Website). It is possible to read the advisory at securityfocus.com. This vulnerability is uniquely identified as CVE-2017-16914 since 11/21/2017. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit.

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 $5k-$25k. 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 197104 (Ubuntu Security Notification for Linux, Linux-aws, Linux-kvm, Linux-raspi2, Linux-snapdragon Vulnerabilities (USN-3619-1)).

Upgrading to version 4.14.8 eliminates this vulnerability. A possible mitigation has been published 3 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (108748), SecurityFocus (BID 102150†) and CERT Bund (WID-SEC-2022-0532). See VDB-109135, VDB-112680, VDB-112681 and VDB-112682 for similar entries. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
