CVE-2018-1062 is a data exposure vulnerability affecting oVirt 4.1.x before 4.1.9, specifically the redhat ovirt-engine. When "Enable Discard" and "Wipe After Delete" flags are used for VM disks, the disk may be incompletely zeroed upon removal. This medium-severity vulnerability (CVSS 5.3) could lead to sensitive data exposure to privileged users of a new VM if the same storage blocks are reallocated. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
