Description
On BIG-IP version 16.x before 16.1.0, 15.1.x before 15.1.3.1, 14.1.x before 14.1.4.2, 13.1.x before 13.1.4.1, and all versions of 12.1.x and 11.6.x, when the Intel QuickAssist Technology (QAT) compression driver is used on affected BIG-IP hardware and BIG-IP Virtual Edition (VE) platforms, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
