K16852653 : TMM vulnerability CVE-2022-32455

Security Advisory Description

When a BIG-IP LTM Client SSL profile is configured on a virtual server to perform client certificate authentication with session tickets enabled, undisclosed requests cause the Traffic Management Microkernel (TMM) to terminate. (CVE-2022-32455)

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.
