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.

A vulnerability classified as critical has been found in Linux Kernel up to 2.6.23 (Operating System). This affects an unknown function of the file drivers/media/video/videobuf-vmalloc.c. The manipulation with an unknown input leads to a memory corruption vulnerability (Leak). 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:

drivers/media/video/videobuf-vmalloc.c in the Linux kernel before 2.6.24 does not initialize videobuf_mapping data structures, which allows local users to trigger an incorrect count value and videobuf leak via unspecified vectors, a different vulnerability than CVE-2010-5321.

The bug was discovered 12/08/2007. The weakness was published 04/24/2017 (Website). The advisory is shared at linuxgrill.com. This vulnerability is uniquely identified as CVE-2007-6761 since 04/23/2017. An attack has to be approached locally. The successful exploitation requires a authentication. Technical details are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 3425 days. During that time the estimated underground price was around $5k-$25k.

Upgrading to version 2.6.24 eliminates this vulnerability.
