Linux Kernel 2.6.16.9 agp_generic_remove_memory input validation

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 2.6.16.9 (Operating System). This issue affects the function agp_generic_remove_memory. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The agp_generic_remove_memory function in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 does not validate a certain start parameter, which allows local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_UNBIND agp_ioctl ioctl call, a different vulnerability than CVE-2011-1745.

The issue has been introduced in 03/20/2006. The weakness was published 05/09/2011 (Website). It is possible to read the advisory at lkml.org. The identification of this vulnerability is CVE-2011-2022. Attacking locally is a requirement. No form of authentication is needed for a successful exploitation. Technical details of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 11/07/2021).

The vulnerability was handled as a non-public zero-day exploit for at least 1876 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 55609 (CentOS 5 : kernel (CESA-2011:0927)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165570 (SUSE Enterprise Linux Security Update Linux Kernel (SUSE-SA:2011:034)).
