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
Information disclosure while decoding Tracking Area Update Accept or Attach Accept message received from network.

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

This vulnerability exists in the decoding logic of Tracking Area Update Accept and Attach Accept messages within a mobile network protocol stack. When processing these 3GPP mobility management messages received from the network, the decoder improperly handles certain fields or structures, leading to information disclosure. This could expose sensitive mobile subscriber data or network configuration details during the decode operation.

MitigationApply the vendor-provided patch to the protocol stack library that handles 3GPP mobility management message decoding. If no patch is available, contact the affected product vendor or library maintainer for remediation guidance.

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 the Qualcomm firmware version
    Check the system firmware version or boot logs for the Qualcomm chip model (Qcn9024, Qcs4490, Qcs5430, Qcs6490, Qcs8550, Qep8111, Qfw7114, or Qfw7124). Use 'cat /proc/version' or check boot logs for the firmware identifier.
    Affected if The device runs any version of the listed Qualcomm firmware products
  2. Confirm 3GPP mobility management stack is active
    Check if the mobile network protocol stack handling LTE/5G mobility management (Tracking Area Update and Attach procedures) is enabled. Inspect running processes or loaded modules related to 3GPP MM (Mobility Management) - look for processes handling 'NAS' (Non-Access Stratum) or 'EMM' (EPS Mobility Management) protocols.
    Affected if The 3GPP mobility management message decoder is actively processing TAU Accept or Attach Accept messages from the network
  3. Review decoder logs for malformed message handling
    Inspect protocol stack logs for error messages or warnings related to Tracking Area Update Accept or Attach Accept message parsing. Look for indications of decoder failures, buffer issues, or unexpected field handling during 3GPP mobility management message processing.
    Affected if Logs show decoder errors, crashes, or anomalous behavior when processing TAU Accept or Attach Accept messages
  4. Check for information disclosure indicators
    Monitor network or debug logs for unexpected data exposure during mobility management message decode operations. Look for leaked memory contents, unexpected subscriber data appearing in logs, or malformed data structures in protocol analysis outputs.
    Affected if Subscriber identity (IMSI), location area codes, or network configuration data appears unexpectedly in logs or debug outputs during message decoding

If the system uses any of the affected Qualcomm firmware products (Qcn9024, Qcs4490, Qcs5430, Qcs6490, Qcs8550, Qep8111, Qfw7114, Qfw7124) and processes 3GPP mobility management messages (TAU Accept or Attach Accept), the environment is potentially affected by this information disclosure vulnerability.

Mitigation

Apply the vendor-provided patch to the protocol stack library that handles 3GPP mobility management message decoding. If no patch is available, contact the affected product vendor or library maintainer for remediation guidance.
