CVE-2025-53856 Details
Description
When a virtual server, network address translation (NAT) object, or secure network address translation (SNAT) object uses the embedded Packet Velocity Acceleration (ePVA) feature, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. To determine which BIG-IP platforms have an ePVA chip refer to K12837: Overview of the ePVA feature https://my.f5.com/manage/s/article/K12837 . Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
A denial-of-service vulnerability has been identified in F5 BIG-IP systems when a virtual server, network address translation (NAT) object, or secure NAT (SNAT) object utilizes the embedded Packet Velocity Acceleration (ePVA) feature, and the 'Auto Last Hop' setting is disabled. Under these conditions, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to crash, disrupting services while the TMM process restarts. This issue affects BIG-IP versions 15.1.0 through 15.1.10, 16.1.0 through 16.1.6, and 17.1.0 through 17.1.2.
Users can upgrade to BIG-IP versions 15.1.10.8, 16.1.6.1, or 17.1.3 to address this vulnerability. For systems with high availability (HA) clustering, F5 recommends configuring the HA table to manage specific actions related to this vulnerability.
