CVE-2019-8934 [LOW] CVE-2019-8934 QEMU: ppc64: sPAPR emulator leaks the host hardware identity
CVE-2019-8934 QEMU: ppc64: sPAPR emulator leaks the host hardware identity
It was found that the KVM PPC64 emulator for the sPAPR machine leaks the host
hardware identity to all running guests. The sPAPAR(hw/ppc/spapr.c) emulator
populates the device tree for the guest with two fields "host-serial"
and "host-model". The values for these fields are taken via hypervisor from
the host device tree data exposed in "/proc/device-tree/system-id"
and "/proc/device-tree/model" file respectively.
