CVE-2016-7498
OpenStack Compute (nova) 13.0.0 does not properly delete instances from compute nodes, which allows remote authenticated users to cause a denial of service (disk consumption) by deleting instances while in the resize state.
Does this matter?
Lower severity and a low EPSS score (2.34%). Track it; it rarely justifies an emergency change on its own.
