Authenticated memory exhaustion via undisclosed REST requests
Published Oct 19, 2022 · Updated May 8, 2025
Resource exhaustion in affected F5 BIG-IP and BIG-IQ releases allows remote authenticated users to increase memory use through iControl REST. F5 identifies iControl REST as the affected locus but has not disclosed which request-handling operation allocates or retains memory incorrectly. A valid iControl REST account and management-network access are required; successful exploitation degrades availability through memory pressure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
