A vulnerability was fixed in DPDK.

Some downstream stakeholders were warned in advance

in order to coordinate the release of fixes

and reduce the vulnerability window.

In DPDK Vhost communication, we didn't test if msg->payload.inflight.num_queues is out of bounds in function ‘vhost_user_set_inflight_fd()’, and could cause the program to write OOB.
