What is CVE-2016-7498?

OpenStack Compute (nova) version 13.0.0 features a vulnerability where instances can fail to be deleted properly from compute nodes. This issue arises when remote authenticated users delete instances that are in a resize state, potentially leading to denial of service through disk consumption. This vulnerability exists due to a regression introduced in a previous CVE (CVE-2015-3280), highlighting the importance of maintaining robust operational protocols in cloud environments.
