Linux Kernel 2.6.16.9 snd_hdspm_hwdep_ioctl information disclosure

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.

A vulnerability, which was classified as problematic, was found in Linux Kernel 2.6.16.9 (Operating System). This affects the function snd_hdspm_hwdep_ioctl. The manipulation with an unknown input leads to a information disclosure vulnerability. 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. The summary by CVE is:

The snd_hdspm_hwdep_ioctl function in sound/pci/rme9652/hdspm.c in the Linux kernel before 2.6.36-rc6 does not initialize a certain structure, which allows local users to obtain potentially sensitive information from kernel stack memory via an SNDRV_HDSPM_IOCTL_GET_CONFIG_INFO ioctl call.

The issue has been introduced in 03/20/2006. The weakness was shared 11/30/2010 by Dan Rosenberg as Bug 648670 as not defined bug report (Bugzilla). The advisory is shared at bugzilla.redhat.com. This vulnerability is uniquely identified as CVE-2010-4081. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1592 for this issue.

The vulnerability was handled as a non-public zero-day exploit for at least 1716 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 50825 (Debian DSA-2126-1 : linux-2.6 - privilege escalation/denial of service/information leak), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165622 (SUSE Enterprise Linux Security Update Linux kernel (SUSE-SA:2010:060)).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
