REDHAT-BUG-1986094: Low severity oracle libvirt vulnerability

Published Jul 26, 2021
·
Updated

A flaw was found in the libvirt virStoragePoolLookupByTargetPath API. The storagePoolLookupByTargetPath() function does not properly release a locked object (virStoragePoolObj) on ACL permission failure. Clients connecting to the read-write socket with limited ACL permissions could use this flaw to acquire the lock and prevent other users from accessing storage pool/volume APIs, resulting in a denial of service condition.
