Linux Kernel up to 4.4.0 IOCTL Call seq_queue.c queue_delete race condition

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 critical, has been found in Linux Kernel up to 4.4.0 (Operating System). This issue affects the function queue_delete of the file sound/core/seq/seq_queue.c of the component IOCTL Call Handler. The manipulation with an unknown input leads to a race condition vulnerability. Using CWE to declare the problem leads to CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Race condition in the queue_delete function in sound/core/seq/seq_queue.c in the Linux kernel before 4.4.1 allows local users to cause a denial of service (use-after-free and system crash) by making an ioctl call at a certain time.

The weakness was published 04/27/2016 (Website). It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2016-2544 since 02/22/2016. Attacking locally is a requirement. The requirement for exploitation is a simple authentication. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 89122 (Debian DSA-3503-1 : linux - security update), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 157744 (Oracle Enterprise Linux Security Update for Unbreakable Enterprise kernel (ELSA-2018-4145)).

Upgrading to version 4.4.1 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.
