Code injection

arch/x86/kvm/vmx.c in the Linux kernel through 4.6.3 mishandles the APICv on/off state, which allows guest OS users to obtain direct APIC MSR access on the host OS, and consequently cause a denial of service host OS crash or possibly execute arbitrary code on the host OS, via x2APIC mode...

FreeBSD : xen-kernel -- VMX: intercept issue with INVLPG on non-canonical address (80adc394-ddaf-11e5-b2bd-002590263bf5)

The Xen Project reports : While INVLPG does not cause a General Protection Fault when used on a non-canonical address, INVVPID in its 'individual address' variant, which is used to back the intercepted INVLPG in certain cases, fails in such cases. Failure of INVVPID results in a hypervisor bug...
