CVE-2026-59762
7.5
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
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.
