Linux Kernel up to 2.6.x perfmon.c mm_struct 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 was found in Linux Kernel up to 2.6.x (Operating System) and classified as problematic. This issue affects the function mm_struct of the file perfmon.c. 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. The summary by CVE is:

perfmon (perfmon.c) in Linux kernel on IA64 architectures allows local users to cause a denial of service (crash) by interrupting a task while another process is accessing the mm_struct, which triggers a BUG_ON action in the put_page_testzero function.

The bug was discovered 02/01/2006. The weakness was presented 04/21/2006 by Cliff Wickman (Website). It is possible to read the advisory at marc.theaimsgroup.com. The identification of this vulnerability is CVE-2006-0558 since 02/06/2006. 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.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 72 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 67556 (Oracle Linux 4 : kernel (ELSA-2007-0774)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 156039 (Oracle Enterprise Linux Update for Kernel Security and Bug Fix Update (ELSA-2007-0774)).
