Host crash due to guest VMX instruction execution
ISSUE DESCRIPTION Permission checks on the emulation paths intended for guests using nested virtualization for VMLAUNCH and VMRESUME were deferred too much. The hypervisor would try to use internal state which is not set up unless nested virtualization is actually enabled for a guest. IMPACT A...
CVE-2013-0151
The dohvmop function in xen/arch/x86/hvm/hvm.c in Xen 4.2.x on the x8632 platform does not prevent HVMPARAMNESTEDHVM aka nested virtualization operations, which allows guest OS users to cause a denial of service long-duration page mappings and host OS crash by leveraging administrative access to ...

CVE-2013-0151
The vulnerability CVE-2013-0151 affects Xen 4.2.x on x86_32 where do_hvm_op does not prevent HVM_PARAM_NESTEDHVM, enabling a guest with admin access in a large-VCPU domain to trigger a denial of service (long-duration page mappings/host crash). The provided documents do not specify a fixed patch ...

nested virtualization on 32-bit exposes host crash
ISSUE DESCRIPTION When performing nested virtualisation Xen would incorrectly map guest pages for extended periods using an interface which is only intended for transient mappings. In some configurations there are a limited number of slots available for these transient mappings and exhausting the...
