Security Advisory
Original Publication Date: 27 Mar, 2020
Security Advisory Description
Under certain conditions, while sending traffic, the Traffic Management

the Data Plane Development Kit (DPDK)/Elastic Network Adapter (ENA) driver on

Impact
A remote attacker may be able to cause TMM to stop processing new traffic and
effect a remote denial of service (DoS).
This issue does not affect any other hardware, virtual platforms, or cloud
provider, as the affected driver is specific to AWS.
