| Vulnerability | Title and context | CVSS | EPSS | PoCs | Signals | STIX action |
|---|---|---|---|---|---|---|
CVE-2026-59762HIGH | Generated title:BIG-IP HTTP/2 Memory Resource Exhaustion Denial of ServiceWhen 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.
