Linux Kernel up to 2.4.34-pre4 ATM clip_mkip uninitialized resource

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.

Detailsinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel up to 2.4.34-pre4 ATM (Operating System). This issue affects the function clip_mkip of the component ATM. The manipulation with an unknown input leads to a uninitialized resource vulnerability. Using CWE to declare the problem leads to CWE-908. The product uses or accesses a resource that has not been initialized. Impacted is availability. The summary by CVE is:

The clip_mkip function in net/atm/clip.c of the ATM subsystem in Linux kernel allows remote attackers to cause a denial of service (panic) via unknown vectors that cause the ATM subsystem to access the memory of socket buffers after they are freed (freed pointer dereference).

The bug was discovered 10/06/2006. The weakness was presented 10/11/2006 by AdLab with Kernel Team (Website). It is possible to read the advisory at secunia.com. The identification of this vulnerability is CVE-2006-4997 since 09/25/2006. Access to the local network is required for this attack to succeed. No form of authentication is needed for a successful exploitation. Technical details of the vulnerability are known, but there is no available exploit.
