kernel: KVM: NULL pointer dereference in kvm_mmu_invpcid_gva

A flaw was found in KVM. With shadow paging enabled if INVPCID is executed with CR0.PG=0, the invlpg callback is not set, and the result is a NULL pointer dereference. This flaw allows a guest user to cause a kernel oops condition on the host, resulting in a denial of service...

x86 PV guest INVLPG-like flushes may leave stale TLB entries

ISSUE DESCRIPTION x86 PV guest kernels may use hypercalls with INVLPG-like behavior to invalidate TLB entries even after changes to non-leaf page tables. Such changes to non-leaf page tables will, however, also render stale possible TLB entries created by Xen's internal use of linear page tables ...

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...
