Description
An integer underflow in dpdk versions before 18.11.10 and before 19.11.5 in the `move_desc` function can lead to large amounts of CPU cycles being eaten up in a long running loop. An attacker could cause `move_desc` to get stuck in a 4,294,967,295-count iteration loop. Depending on how `vhost_crypto` is being used this could prevent other VMs or network tasks from being serviced by the busy DPDK lcore for an extended period.
Affected configurations
• dpdk data plane development kit (>= 18.02.1 < 18.11.10)
• dpdk data plane development kit (>= 19.02 < 19.11.5)
• canonical ubuntu linux 20.04
• opensuse leap 15.1
• opensuse leap 15.2
