CVE-2025-54805
When an iRule is configured on a virtual server via the declarative API, upon re-instantiation, the cleanup process can cause an increase in the Traffic Management Microkernel (TMM) memory resource utilization.
Does this matter?
Lower severity and a low EPSS score (0.31%). Track it; it rarely justifies an emergency change on its own.
