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
The O-RAN E2T I-Release Prometheus metric Increment function can crash in sctpThread.cpp for message.peerInfo->sctpParams->e2tCounters[IN_SUCC][MSG_COUNTER][ProcedureCode_id_RICsubscription]->Increment().

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 denial-of-service vulnerability exists in the O-RAN E2T I-Release Prometheus metric Increment function in sctpThread.cpp. The code crashes when attempting to increment the counter at e2tCounters[IN_SUCC][MSG_COUNTER][ProcedureCode_id_RICsubscription]->Increment(), likely due to missing bounds validation or uninitialized array structures allowing out-of-bounds or null pointer access.

MitigationAdd proper bounds checking to validate the ProcedureCode_id_RICsubscription index before array access, and ensure e2tCounters arrays are fully initialized before use. Alternatively, implement null-pointer guards around the Increment() call.

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 O-RAN E2T installation
    Search for O-RAN E2T or sctpThread.cpp files in the system. Common locations include /opt/oran, /usr/local/oran, or project directories containing O-RAN source code.
    Affected if O-RAN E2T software or source code is present on the system
  2. Locate the vulnerable source file
    Search for sctpThread.cpp in the O-RAN installation directory or source tree. Verify the file contains the e2tCounters array and the Increment() call at ProcedureCode_id_RICsubscription.
    Affected if The file sctpThread.cpp with the vulnerable code pattern is found
  3. Determine software version
    Check for version information in the O-RAN E2T component - look for version files, git tags, or binary metadata. Compare against any released version numbers for the O-RAN software.
    Affected if The installed version is an unpatched release that contains the vulnerable code in sctpThread.cpp
  4. Check for RIC subscription feature
    Inspect configuration files or logs to determine if RIC subscription functionality (ProcedureCode_id_RICsubscription) is enabled or can be triggered in the deployment.
    Affected if RIC subscription feature is enabled and can trigger message processing through the vulnerable code path
  5. Verify counter array initialization
    Examine the e2tCounters array initialization code in the codebase. Check if all three dimensions (IN_SUCC, MSG_COUNTER, ProcedureCode_id_RICsubscription) are properly initialized before use.
    Affected if The e2tCounters array is not fully initialized or lacks proper bounds checking before the Increment() call

A system is affected if it runs O-RAN E2T software containing the vulnerable sctpThread.cpp code where the e2tCounters array access lacks proper bounds validation and RIC subscription messaging can be processed.

Mitigation

Add proper bounds checking to validate the ProcedureCode_id_RICsubscription index before array access, and ensure e2tCounters arrays are fully initialized before use. Alternatively, implement null-pointer guards around the Increment() call.
