# CVE-2022-34844: BIG-IP and BIG-IQ AWS vulnerability CVE-2022-34844

- Severity: CVSS 5.9 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
- Known exploited (CISA KEV): no
- Fixed in: 15.1.6.1, 16.1.3.1
- Published: 2022-08-04 · Updated: 2024-09-16

## Affected

- F5 BIG-IP: from 15.1.x, fixed in 15.1.6.1; from 16.1.x, fixed in 16.1.3.1
- F5 BIG-IQ Centralized Management: from 8.0.0

## Description

In BIG-IP Versions 16.1.x before 16.1.3.1 and 15.1.x before 15.1.6.1, and all versions of BIG-IQ 8.x, 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. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
