Description
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.

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability occurs when a virtual server, network address translation (NAT) object, or secure NAT (SNAT) object uses the embedded Packet Velocity Acceleration (ePVA) feature. Undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate unexpectedly, potentially disrupting network traffic management on affected BIG-IP platforms with the ePVA chip.
How can this vulnerability impact me? :
The impact of this vulnerability is that the Traffic Management Microkernel (TMM) can terminate unexpectedly when processing certain undisclosed traffic on systems using the ePVA feature. This can lead to denial of service conditions, causing network disruptions and potentially affecting availability of services relying on the BIG-IP platform.
