Details
A vulnerability, which was classified as problematic, has been found in Linux Kernel 2.6.16.9 (Operating System). Affected by this issue is the function snd_hdsp_hwdep_ioctl. The manipulation with an unknown input leads to a information disclosure vulnerability. Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. CVE summarizes:
The snd_hdsp_hwdep_ioctl function in sound/pci/rme9652/hdsp.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_HDSP_IOCTL_GET_CONFIG_INFO ioctl call.
The issue has been introduced in 03/20/2006. The weakness was presented 11/30/2010 by Dan Rosenberg as Bug 648669 as not defined bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com. This vulnerability is handled as CVE-2010-4080. The attack needs to be approached locally. No form of authentication is required for exploitation. Technical details as well as a public exploit are known. The MITRE ATT&CK project declares the attack technique as T1592.
The exploit is available at packetstormsecurity.com. It is declared as proof-of-concept. 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 51786 (CentOS 4 : kernel (CESA-2011:0162)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS 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)).
