Name of the Vulnerable Software and Affected Versions F5 BIG-IP versions 15.1.x through 15.1.6.0 F5 BIG-IP versions 16.1.x through 16.1.3.0 F5 BIG-IQ versions 8.x

Description The issue arises when the Data Plane Development Kit (DPDK)/Elastic Network Adapter (ENA) driver is used with BIG-IP or BIG-IQ on Amazon Web Services (AWS) systems. Undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. Successful exploitation relies on conditions outside of the attacker's control.

Recommendations For F5 BIG-IP versions 15.1.x through 15.1.6.0, update to version 15.1.6.1 or later. For F5 BIG-IP versions 16.1.x through 16.1.3.0, update to version 16.1.3.1 or later. For F5 BIG-IQ versions 8.x, consider disabling the DPDK/ENA driver as a temporary workaround until a patch is available.
