Linux Kernel 2.6.16.9 load_mixer_volumes memory corruption

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.

Summaryinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel 2.6.16.9. This impacts the function load_mixer_volumes. Performing a manipulation results in memory corruption. This vulnerability was named CVE-2010-4527. There is no available exploit.

Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel 2.6.16.9 (Operating System). This affects the function load_mixer_volumes. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The load_mixer_volumes function in sound/oss/soundcard.c in the OSS sound subsystem in the Linux kernel before 2.6.37 incorrectly expects that a certain name field ends with a \0 character, which allows local users to conduct buffer overflow attacks and gain privileges, or possibly obtain sensitive information from kernel memory, via a SOUND_MIXER_SETLEVELS ioctl call.

The issue has been introduced in 03/20/2006. The weakness was presented 01/13/2011 by Dan Rosenberg as Bug 667615 as not defined bug report (Bugzilla). It is possible to read the advisory at bugzilla.redhat.com. This vulnerability is uniquely identified as CVE-2010-4527 since 12/09/2010. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 10/11/2021).

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1760 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 68204 (Oracle Linux 4 : kernel (ELSA-2011-0263)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165554 (SUSE Enterprise Linux Security Update Linux Kernel (SUSE-SA:2011:012)).

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

The vulnerability is also documented in the databases at Tenable (68204), SecurityFocus (BID 45629†), Secunia (SA42765†) and Vulnerability Center (SBV-28918†). See VDB-4723, VDB-55675, VDB-55566 and VDB-55562 for similar entries. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
