Linux Kernel up to 2.6.25.4 resource management

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 2.6.25.4 (Operating System). It has been rated as problematic. Affected by this issue is some unknown processing. The manipulation with an unknown input leads to a resource management vulnerability. Using CWE to declare the problem leads to CWE-399. Impacted is availability. CVE summarizes:

The (1) sys32_mremap function in arch/sparc64/kernel/sys_sparc32.c, the (2) sparc_mmap_check function in arch/sparc/kernel/sys_sparc.c, and the (3) sparc64_mmap_check function in arch/sparc64/kernel/sys_sparc.c, in the Linux kernel before 2.6.25.4, omit some virtual-address range (aka span) checks when the mremap MREMAP_FIXED bit is not set, which allows local users to cause a denial of service (panic) via unspecified mremap calls, a related issue to CVE-2008-2137.

The weakness was released 05/27/2008 by Jan Lieskovsky with Linux Kernel Team (Website). The advisory is shared for download at kernel.org. This vulnerability is handled as CVE-2008-6107 since 02/10/2009. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available.

It is declared as proof-of-concept. As 0-day the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 37337 (Ubuntu 7.10 / 8.04 LTS / 8.10 : linux, linux-source-2.6.22 vulnerabilities (USN-751-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Ubuntu Local Security Checks.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (48710), Tenable (37337), SecurityFocus (BID 33836†), OSVDB (56163†) and Secunia (SA30258†). Entry connected to this vulnerability is available at VDB-46587. Once again VulDB remains the best source for vulnerability data.
