CVE-2020-5862Network attack vector

Traffic-processing crash in AWS DPDK/ENA driver

Published Mar 27, 2020 · Updated Aug 4, 2024

Denial of service in affected F5 BIG-IP releases allows remote attackers to crash TMM or halt new traffic on AWS via traffic processing. TMM mishandles traffic under undisclosed conditions in the XNet DPDK/ENA data-plane driver; F5 has not published the faulty operation or triggering traffic pattern. The flaw requires BIG-IP Virtual Edition on AWS with the XNet DPDK/ENA driver; affected releases are 14.1.0 through 14.1.2.2, 15.0.0 through 15.0.1.1, and 15.1.0 through 15.1.0.1, and the result is a TMM restart or refusal of new traffic.
