CVE-2026-2507 is a remote denial-of-service vulnerability in F5 BIG-IP affecting deployments where BIG-IP AFM or BIG-IP DDoS is provisioned. According to the provided advisory content, undisclosed network traffic can trigger termination of the Traffic Management Microkernel (TMM) process. TMM is the core traffic-processing component on BIG-IP systems, so its termination can interrupt packet and traffic handling. The issue is associated with CWE-476. The available information does not disclose the exact vulnerable code path or function, but the attack is described as network-reachable, low complexity, requiring no privileges and no user interaction.
