CVE-2024-24459
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 · uneditedAn invalid memory access when handling the ProtocolIE_ID field of S1Setup Request messages in Athonet vEPC MME v11.4.0 allows attackers to cause a Denial of Service (DoS) to the cellular network by repeatedly initiating connections and sending a crafted payload.
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 confidenceAthonet vEPC MME v11.4.0 contains an invalid memory access vulnerability when parsing the ProtocolIE_ID field within S1Setup Request messages. Attackers can repeatedly initiate connections with a crafted payload to trigger the memory access error, causing a Denial of Service that disrupts cellular network connectivity.

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 Athonet vEPC MME installationLocate the MME software installation directory or check running processes for 'athonet' or 'mme' components. Consult system documentation or inventory if available.Affected if The product is Athonet vEPC MME running version 11.4.0 or earlier 11.x versions.
-
Determine installed MME versionRun the MME version command or check the software binary/version file. Common methods: 'mme --version', checking /opt/athonet/*/version, or reviewing the software release notes.Affected if The installed version is v11.4.0 specifically.
-
Verify S1-MME interface is enabledCheck MME configuration for S1-MME interface settings. Look for S1Setup procedure configuration and peer eNodeB connections.Affected if The S1-MME interface is enabled and the MME is accepting S1Setup Request messages from eNodeBs.
-
Review logs for memory access errorsExamine MME logs for entries indicating invalid memory access, segmentation faults, or crashes during S1Setup Request processing. Search for keywords like 'S1Setup', 'ProtocolIE_ID', 'memory', 'crash', or 'Segmentation fault'.Affected if Logs show memory access errors or crashes occurring during S1Setup Request message parsing.
-
Check for abnormal MME restartsReview system logs or MME process monitoring for unexpected restarts or service interruptions, particularly if correlated with external connection attempts.Affected if The MME experiences repeated unexpected restarts or service disruptions.
A user is affected if they are running Athonet vEPC MME version 11.4.0 with the S1-MME interface enabled, and evidence of memory access errors appears in logs during S1Setup Request processing.

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 dataImplement proper bounds checking and validation on the ProtocolIE_ID field within S1Setup Request message processing to prevent invalid memory access. Consider applying any available vendor patches for vEPC MME v11.4.0.
