Linux Kernel up to 2.4.29-rc1/2.6.10 on SMP race condition

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 classified as problematic was found in Linux Kernel up to 2.4.29-rc1/2.6.10 on SMP (Operating System). Affected by this vulnerability is an unknown code. The manipulation with an unknown input leads to a race condition vulnerability. The CWE definition for the vulnerability is CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Race condition in the page fault handler (fault.c) for Linux kernel 2.2.x to 2.2.7, 2.4 to 2.4.29, and 2.6 to 2.6.10, when running on multiprocessor machines, allows local users to execute arbitrary code via concurrent threads that share the same virtual memory space and simultaneously request stack expansion.

The bug was discovered 01/12/2005. The weakness was disclosed 01/12/2005 by Paul Starzetz with isec.pl (Website). The advisory is shared at isec.pl. This vulnerability is known as CVE-2005-0001 since 01/03/2005. The attack needs to be initiated within the local network. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available.

After 1 days, there has been an exploit disclosed. It is possible to download the exploit at isec.pl. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 16166 (Fedora Core 3 : kernel-2.6.10-1.741_FC3 (2005-025)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 115055 (Linux Kernel Multiple Vulnerabilities (RHSA-2005:092-14)).

Upgrading eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at ftp.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published 1 days after the disclosure of the vulnerability.
