Detailed vulnerability description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input while processing specifically crafted traffic using the default "xnet" driver. A remote attacker can cause the Traffic Management Microkernel (TMM) process to restart and perform a denial-of-service attack on the BIG-IP Virtual Edition (VE) system hosted in Amazon Web Services (AWS).
