Linux Kernel up to 2.6.16 SCTP IP Fragmentation denial of service

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 critical, has been found in Linux Kernel up to 2.6.16 (Operating System). Affected by this issue is an unknown code of the component SCTP IP Fragmentation Handler. The manipulation with an unknown input leads to a denial of service vulnerability. Using CWE to declare the problem leads to CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. Impacted is availability. CVE summarizes:

The ECNE chunk handling in Linux SCTP (lksctp) before 2.6.17 allows remote attackers to cause a denial of service (kernel panic) via an unexpected chunk when the session is in CLOSED state.

The bug was discovered 05/08/2006. The weakness was released 05/09/2006 by Mu Security with Mu Security research team (Website). The advisory is shared for download at labs.musecurity.com. This vulnerability is handled as CVE-2006-2271 since 05/09/2006. The attack may be launched remotely. No form of authentication is required for exploitation.
