To confirm a new failure in 5.2.3 you would need to show a test that passes on 5.2.2 and fails on 5.2.3. As Paolo suspected, kvm-unit-tests/master fails on 5.2.* and passes if commit 95d6d2c ("nVMX: Test Host Segment Registers and Descriptor Tables on vmentry of nested guests") is reverted (from kvm-unit-tests). The failures are quite clearly in the new test(s).
