A vulnerability, which was classified as problematic, was found in Linux Kernel 2.6.16.9 (Operating System). Affected is the function hso_get_count. 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. CVE summarizes:

The hso_get_count function in drivers/net/usb/hso.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 TIOCGICOUNT ioctl call.

The issue has been introduced in 03/20/2006. The weakness was released 09/30/2010 by Dan Rosenberg as confirmed git commit (GIT Repository). The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2010-3298. The exploitability is told to be easy. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1592.

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 68177 (Oracle Linux 6 : kernel (ELSA-2011-0007)), 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.

The vulnerability is also documented in the vulnerability database at Tenable (68177). Entries connected to this vulnerability are available at 54874, 54794, 54644 and 54636.
