Technical description
The libxlDomainGetNumaParameters function in the libxl driver (libxl/libxl_driver.c) in libvirt before 1.2.1 does not properly initialize the nodemap, which allows local users to cause a denial of service (invalid free operation and crash) or possibly execute arbitrary code via an inactive domain to the virsh numatune command.
Remediation
Check the references section for vendor advisories and patches from redhat. Update libvirt to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
