  "details" : [ "A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A lack of bounds checking when copying iv_data from the VM guest memory into host memory can lead to a large buffer overflow. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.", "A flaw was found in dpdk.

The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability." ],
  "statement" : "This flaw does not affect the versions of `dpdk` as shipped with Red Hat Enterprise Linux 7 and 8 or the versions embedded in Red Hat Virtualization or the Fast Datapath `openvswitch` package, as they do not enable generic crypto device library support. This causes the vulnerable code in vhost_crypto.c to not be included.\nThis flaw does not affect Red Hat Ceph Storage 3 and 4 as dpdk (embedded in ceph source rpm) is not built in the packages, therefore the vulnerable code is not available in the resulting RPM and the issue cannot be exploited.",
