Detailsinfo

A vulnerability classified as problematic was found in Linux Kernel 3.1.2 (Operating System). Affected by this vulnerability is an unknown functionality of the file sb105x/sb_pci_mp.c. 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, and integrity. The summary by CVE is:

The mp_get_count function in drivers/staging/sb105x/sb_pci_mp.c in the Linux kernel before 3.12 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call.

The weakness was shared 10/30/2013 by Fabian Yamaguchi and Nico Golde as some unstracked linux kernel security fixes as confirmed mailinglist post (oss-sec). The advisory is shared at seclists.org. The vendor cooperated in the coordination of the public release. This vulnerability is known as CVE-2013-4516 since 06/12/2013. An attack has to be approached locally. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1592 for this issue.

The vulnerability scanner Nessus provides a plugin with the ID 71795 (Ubuntu 12.04 LTS : linux-lts-raring vulnerabilities (USN-2069-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Ubuntu Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 195832 (Ubuntu Security Notification for Linux-lts-raring Vulnerabilities (USN-2069-1)).

Applying the patch Staging: sb105x: info leak in mp_get_count() is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (71795), OSVDB (99322†) and Vulnerability Center (SBV-42197†). Additional details are provided at http://Staging: sb105x: info leak in mp_get_count(). The entries VDB-11090, VDB-11092, VDB-11093 and VDB-11094 are related to this item. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
