CVE-2025-36504 Details
Description
When a BIG-IP HTTP/2 httprouter profile is configured on a virtual server, undisclosed responses can cause an increase in memory resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
A vulnerability exists in F5 BIG-IP systems when a virtual server is configured with an HTTP/2 httprouter profile. Undisclosed responses can cause increased memory resource utilization, leading to degraded system performance. This degradation can force a restart of the Traffic Management Microkernel (TMM) process, causing a denial-of-service (DoS) condition on the BIG-IP system. This issue is a data plane problem only, with no control plane exposure.
Users can remove the HTTP/2 profile and httprouter definitions from the virtual server to mitigate this vulnerability. For BIG-IP Next systems, consult the BIG-IP Next Central Manager documentation for guidance on managing HTTP/2 profiles. Additionally, systems with high availability (HA) can be configured to lessen the impact of this vulnerability.
