A vulnerability was found in DPDK versions 19.11 and above. A malicious container that has direct access to the vhost-user socket can keep sending VHOST_USER_GET_INFLIGHT_FD messages, causing a resource leak (file descriptors and virtual memory), which may result in a denial of service.

• CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
