CVE-2025-47150Network attack vector

Authenticated service interruption via SNMP memory leak

Published Oct 15, 2025 · Updated Oct 15, 2025

Denial of service in SNMP on affected F5 F5OS-A and F5OS-C releases allows remote authenticated users to exhaust SNMP memory. The SNMP service fails to release memory after processing unspecified requests, causing resource utilization to grow; F5 has not disclosed the request format or code locus. SNMP must be configured and low-privileged credentials are required; successful exploitation can interrupt appliance availability without affecting confidentiality or integrity.
