Security readout for executives and security teams
Plain-English summary
CVE-2024-24442 can crash the OpenAirInterface CN5G AMF when it processes a specially crafted NGAP message. The business impact is service availability: affected 5G core deployments could lose AMF functionality until recovered. The public metadata does not identify confirmed active exploitation or a specific vendor fix.
Executive priority
Treat as high priority where OpenAirInterface CN5G AMF supports real or test 5G core services. The risk is outage, not data theft, but unauthenticated network reachability raises operational urgency.
Technical view
The issue is a NULL pointer dereference in ngap_app::handle_receive in OpenAirInterface CN5G AMF, reported up to v2.0.0. CVSS 3.1 is 7.5: network reachable, low complexity, no privileges, no user interaction, with high availability impact only.
Likely exposure
Exposure is most likely in organizations running OpenAirInterface CN5G AMF, especially versions up to v2.0.0. The CVE affected-product metadata is not normalized, so inventory confirmation is required.
Exploitation context
The sources describe denial of service via a crafted NGAP message. CISA KEV status is false in the bundle, and no provided source confirms active exploitation in the wild.
Researcher notes
Evidence is limited to public CVE metadata and the referenced RANsacked material. The record names the vulnerable routine and impact, but the affected-product fields are marked n/a and no definitive patch information is included in the bundle.
Mitigation direction
- Identify any OpenAirInterface CN5G AMF deployments and their exact versions.
- Check OpenAirInterface or project guidance for fixed versions or patches.
- Prioritize reducing untrusted network reachability to AMF NGAP-facing services.
- Increase monitoring for AMF crashes, restarts, or abnormal NGAP handling.
- Plan upgrade or compensating controls for versions up to v2.0.0.
Validation and detection
- Confirm whether OpenAirInterface CN5G AMF is present in production or lab networks.
- Compare deployed AMF versions against the reported affected range up to v2.0.0.
- Review AMF availability logs for crashes or unexpected restarts.
- Verify NGAP-facing interfaces are reachable only from expected network peers.
- Track CVE Program updates for clarified affected-product and remediation data.

NULL Pointer Dereference
NULL Pointer Dereference represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
