K37708118 : BIG-IP DNS profile vulnerability CVE-2023-22839

Security Advisory Description

When a DNS profile with the Rapid Response Mode setting enabled is configured on a virtual server with hardware SYN cookies enabled, undisclosed requests cause the Traffic Management Microkernel (TMM) to terminate. (CVE-2023-22839)

Impact

Traffic is disrupted while the TMM process restarts. This vulnerability allows a remote unauthenticated attacker to cause a denial-of-service (DoS) on the BIG-IP system. There is no control plane exposure; this is a data plane issue only.
