CVE-2025-41431

Estado: AnalizadaAlta (8.7)—

When connection mirroring is configured on a virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate in the standby BIG-IP systems in a traffic group.

Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
