Detailsinfo

A vulnerability was found in Linux Kernel 2.6.28.2 (Operating System). It has been classified as problematic. Affected is the function pci_register_iommu_region. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as 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. This is going to have an impact on availability. CVE summarizes:

The pci_register_iommu_region function in arch/sparc/kernel/pci_common.c in the Linux kernel before 2.6.29 on the sparc64 platform allows local users to cause a denial of service (system crash) by reading the /proc/iomem file, related to uninitialized pointers and the request_resource function.

The issue has been introduced in 12/25/2008. The weakness was released 06/04/2009 by Mikulas Patocka (Website). The advisory is available at xforce.iss.net. This vulnerability is traded as CVE-2009-1914 since 06/04/2009. The exploitability is told to be easy. Local access is required to approach this attack. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known.

The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 161 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 44709 (Debian DSA-1844-1 : linux-2.6.24 - denial of service/privilege escalation), which helps to determine the existence of the flaw in a target environment.
