"The remote device is missing a vendor-supplied security patch.");

"When the BIG-IP Virtual Edition (VE) is configured with VLAN groups
and there are devices configured with OSPF connected to it, the
Network Device Abstraction Layer (NDAL) Interfaces can lock up and in
turn disruptingthe communication between the mcpd and tmm
processes(CVE-2020-5881).

Impact

This issue only affects BIG-IP VE. The BIG-IP system temporarily fails
to process traffic as it recovers from a Traffic Management
Microkernel (TMM)restart, and devices configured in a device group may
fail over.");
