Security readout for executives and security teams
Plain-English summary
CVE-2024-24443 can crash the OpenAirInterface 5G core AMF component, disrupting availability. The issue is triggered by a crafted 5G signaling response. Sources identify affected oai-cn5g-amf versions up to v2.0.0. No public source in the bundle confirms active exploitation or a specific patch.
Executive priority
Treat as a service-availability risk for affected 5G core environments. Prioritize validation if OpenAirInterface supports production, demos, or critical private 5G services. Urgency is lower where OAI is not deployed.
Technical view
The flaw is described as an uninitialized pointer dereference in ngap_handle_pdu_session_resource_setup_response in OpenAirInterface CN5G AMF. A crafted PDU Session Resource Setup Response can cause denial of service. CVSS is 6.5, AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H, with CWE-476 listed.
Likely exposure
Exposure is likely limited to organizations running OpenAirInterface CN5G AMF up to v2.0.0 in lab, research, private 5G, or telecom environments. Internet exposure is not established by the provided sources.
Exploitation context
The CVE record indicates network attack vector and low complexity, but user interaction is listed in CVSS. The bundle does not show CISA KEV listing, confirmed exploitation, public exploit availability, or real-world incidents.
Researcher notes
Source detail is sparse. The CVE names the vulnerable routine and message type but does not provide remediation details. The affected product table is incomplete, while the description names oai-cn5g-amf up to v2.0.0.
Mitigation direction
- Identify any deployments of OpenAirInterface CN5G AMF.
- Confirm whether oai-cn5g-amf is version v2.0.0 or earlier.
- Check OpenAirInterface and CVE references for vendor remediation guidance.
- Restrict access to AMF signaling interfaces to trusted network segments.
- Increase monitoring for AMF crashes or unexpected restarts.
Validation and detection
- Review AMF package, container, or source version metadata.
- Check deployment inventories for oai-cn5g-amf.
- Review logs for crashes around PDU session setup handling.
- Confirm whether vendor guidance or fixed releases are available.
- Document compensating network controls around AMF interfaces.
