Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 3.9.11 on ARM (Operating System). This issue affects the function KVM_GET_REG_LIST of the file arch/arm/kvm/arm.c of the component Virtual Machine Support. The manipulation with an unknown input leads to a resource management vulnerability. Using CWE to declare the problem leads to CWE-399. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

arch/arm/kvm/arm.c in the Linux kernel before 3.10 on the ARM platform, when KVM is used, allows host OS users to cause a denial of service (NULL pointer dereference, OOPS, and host OS crash) or possibly have unspecified other impact by omitting vCPU initialization before a KVM_GET_REG_LIST ioctl call.

The weakness was presented 06/03/2013 as ARM: KVM: prevent NULL pointer dereferences with KVM VCPU ioctl as confirmed git commit (GIT Repository). The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2013-5634 since 08/26/2013. The exploitation is known to be difficult. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 95592 (openSUSE Security Update : the Linux Kernel (openSUSE-2016-1410)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 169559 (OpenSuSE Security Update for the Linux Kernel (openSUSE-SU-2016:3021-1)).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (95592), SecurityFocus (BID 61995†) and OSVDB (96598†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
