TMM crash via expired pointer dereference
Published May 8, 2024 · Updated Aug 2, 2024
Expired pointer dereference in F5 BIG-IP allows remote attackers to crash the Traffic Management Microkernel through SSL traffic. When a virtual server uses an SSL profile with a non-default alert timeout, undisclosed traffic dereferences an expired pointer and terminates TMM. No authentication or user interaction is required, but exploitation also depends on conditions outside the attacker's control and causes a traffic-processing service interruption.
