Detailsinfo

A vulnerability classified as problematic was found in Linux Kernel 2.6.16.9 (Operating System). This vulnerability affects the function cxgb_extension_ioctl. The manipulation with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality. CVE summarizes:

The cxgb_extension_ioctl function in drivers/net/cxgb3/cxgb3_main.c in the Linux kernel before 2.6.36-rc5 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a CHELSIO_GET_QSET_NUM ioctl call.

The issue has been introduced in 03/20/2006. The weakness was shared 09/30/2010 by Dan Rosenberg as confirmed git commit (GIT Repository). The advisory is available at git.kernel.org. This vulnerability was named CVE-2010-3296. The exploitation appears to be easy. Local access is required to approach this attack. No form of authentication is required for a successful exploitation. Technical details and also a public exploit are known. This vulnerability is assigned to T1592 by the MITRE ATT&CK project.

It is possible to download the exploit at packetstormsecurity.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1655 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 68247 (Oracle Linux 6 : kernel (ELSA-2011-0421)), 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 165615 (SUSE Enterprise Linux Security Update Linux Kernel (SUSE-SA:2010:050)).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at git.kernel.org.
