CVE-2026-59762 When an HTTP/2 profile is configured on a virtual server, undisclosed requests can cause an increase in memory…

Description

When an HTTP/2 profile is configured on a virtual server, undisclosed requests can cause an increase in memory resource utilization.   Impact: System performance can degrade until the TMM process is either forced to restart or is manually restarted. This vulnerability allows a remote, unauthenticated attacker to cause a degradation of service that can lead to a denial-of-service (DoS) on the BIG-IP system. There is no control plane exposure; this is a data plane issue only. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
