The WRMSR processing functionality in the KVM subsystem in the Linux kernel through 3.17.2 does not properly handle the writing of a non-canonical address to a model-specific register, which allows guest OS users to cause a denial of service (host OS crash) by leveraging guest OS privileges, related to the wrmsr_interception function in arch/x86/kvm/svm.c and the handle_wrmsr function in arch/x86/kvm/vmx.c.

CVE-2014-3610 [MEDIUM] KVM: x86: Check non-canonical addresses upon WRMSR
KVM: x86: Check non-canonical addresses upon WRMSR
Upon WRMSR, the CPU should inject #GP if a non-canonical value (address) is
written to certain MSRs. The behavior is "almost" identical for AMD and Intel
(ignoring MSRs that are not implemented in either architecture since they would
anyhow #GP). However, IA32_SYSENTER_ESP and IA32_SYSENTER_EIP cause #GP if
non-canonical address is written on Intel but not on AMD (which ignores the top
32-bits).
Accordingly, this patch injects a #GP on the MSRs which behave identically on
Intel and AMD. To eliminate the differences between the architecutres, the
value which is written to IA32_SYSENTER_ESP and IA32_SYSENTER_EIP is turned to
canonical value before writing instead of injecting a #GP.

CVE-2014-3610 kernel: kvm: noncanonical MSR writes
If the guest writes a noncanonical value to certain MSR registers, KVM will
write that value to the MSR in the host context and a #GP will be raised
leading to kernel panic.
A privileged guest user can use this flaw to crash the host.
Enabling CONFIG_PARAVIRT when building the kernel mitigates this issue because wrmsrl() ends up invoking safe msr write variant.
