CVE-2024-24427
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 · uneditedA reachable assertion in the amf_ue_set_suci function of Open5GS <= 2.6.4 allows attackers to cause a Denial of Service (DoS) via a crafted NAS packet.
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 confidenceA reachable assertion in the amf_ue_set_suci function of Open5GS versions 2.6.4 and earlier allows remote attackers to trigger a denial of service by sending a crafted NAS (Non-Access Stratum) message that causes the assertion to fail, crashing the AMF (Access and Mobility Management Function) process.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed Open5GS versionRun the command to display the Open5GS version installed in your environment (for example, 'open5gs --version' or check the package manager for installed version)Affected if The displayed version is 2.6.4 or any version lower than 2.6.4
-
Verify AMF component is activeCheck if the AMF (Access and Mobility Management Function) process is running (for example, 'ps aux | grep amf' or check service status)Affected if The AMF process is running and exposed to network traffic
-
Review logs for assertion failuresExamine system or application logs for messages containing 'amf_ue_set_suci' and 'assertion' or 'failed' keywords around the time of any service disruptionsAffected if Logs show assertion failures in the amf_ue_set_suci function or unexpected AMF process crashes
-
Inspect NAS message handlingIf you have access to packet captures or NAS message inspection tools, verify whether inbound NAS messages with SUCI (Subscription Concealed Identifier) data are being processed by the AMFAffected if NAS messages with SUCI data are reaching the AMF without prior validation
Your environment is affected if Open5GS version 2.6.4 or earlier is installed and the AMF component is processing incoming NAS messages with SUCI data.
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.
From vendor dataUpgrade to a patched version of Open5GS if available; otherwise, implement input validation on incoming NAS packets before they reach the amf_ue_set_suci function to reject malformed SUCI (Subscription Concealed Identifier) data that triggers the assertion.
