Description

Under certain conditions, a data leak may occur in the Traffic Management Microkernels (TMMs) of BIG-IP tenants running on VELOS and rSeries platforms. This leak occurs randomly and cannot be deliberately triggered. If it occurs, it may leak up to 64 bytes of non-contiguous randomized bytes.
