CVE-2022-23010Network attack vector

Service interruption via request-triggered memory exhaustion

Published Jan 25, 2022 · Updated Aug 3, 2024

Resource exhaustion in F5 BIG-IP allows remote attackers to interrupt service with undisclosed requests to configured virtual servers. F5 has not disclosed which request property triggers the flaw or the exact resource-lifecycle error that increases memory use. Exposure requires both FastL4 and HTTP profiles on the same virtual server; resulting memory exhaustion affects availability, with no reported data access or code execution.
