======================================================
Name: CVE-2009-1914
Status: Candidate
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1914
Reference: MLIST:[oss-security] 20090603 CVE request: kernel: sparc64: Fix crash with /proc/iomem
Reference: URL:http://www.openwall.com/lists/oss-security/2009/06/03/3
Reference: CONFIRM:http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=192d7a4667c6d11d1a174ec4cad9a3c5d5f9043c
Reference: CONFIRM:http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.29

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.
