Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A buffer overflow in the ngap_amf_handle_pdu_session_resource_setup_response function of oai-cn5g-amf up to v2.0.0 allows attackers to cause a Denial of Service (DoS) via a PDU Session Resource Setup Response with an empty Response Item list.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A buffer overflow vulnerability exists in the ngap_amf_handle_pdu_session_resource_setup_response function of oai-cn5g-amf (OpenAirInterface 5G AMF) up to v2.0.0. The vulnerability is triggered when processing a PDU Session Resource Setup Response message containing an empty Response Item list, causing a buffer overflow and resulting in Denial of Service.

MitigationUpgrade oai-cn5g-amf to a version beyond v2.0.0 that contains the security fix. Until patched, implement input validation at the NGAP layer to reject PDU Session Resource Setup Response messages with empty Response Item lists.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify oai-cn5g-amf version
    Check the installed version of oai-cn5g-amf (e.g., via --version flag, docker image tag, package metadata, or binary information)
    Affected if Version is v2.0.0 or any version prior to v2.0.0
  2. Confirm AMF is processing NGAP traffic
    Verify the AMF service is running and actively handling NGAP connections (check process status, logs, or confirm the service is listening on the SCTP NGAP port)
    Affected if AMF is operational and processing NGAP sessions
  3. Check if PDU Session Resource handling is enabled
    Review AMF configuration files or runtime settings to confirm PDU Session Resource Setup Response processing is permitted
    Affected if PDU Session Resource management is enabled in the AMF configuration

If oai-cn5g-amf version is v2.0.0 or lower and the AMF is actively processing NGAP messages, the environment is affected by this vulnerability.

Generated from the published advisory. Verify against your own configuration.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade oai-cn5g-amf to a version beyond v2.0.0 that contains the security fix. Until patched, implement input validation at the NGAP layer to reject PDU Session Resource Setup Response messages with empty Response Item lists.
