Name of the Vulnerable Software and Affected Versions DPDK versions 19.11 and above

Description A vulnerability was found that allows a malicious container with direct access to the vhost-user socket to cause a resource leak by sending VHOST USER GET INFLIGHT FD messages. This can result in a denial of service due to the depletion of file descriptors and virtual memory.

As a temporary workaround, monitor system resources closely to detect potential resource leaks. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
