Описание

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A complete lack of validation of attacker-controlled parameters can lead to a buffer over read. The results of the over read are then written back to the guest virtual machine memory. This vulnerability can be used by an attacker in a virtual machine to read significant amounts of host memory. The highest threat from this vulnerability is to data confidentiality and system availability.

Отчет

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. This 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.
