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
In GetCellInfoList() of protocolnetadapter.cpp, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with baseband firmware compromise required. User Interaction is not needed for exploitation.

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 · high confidence

An out-of-bounds read vulnerability exists in the GetCellInfoList() function within protocolnetadapter.cpp due to a missing bounds check. This allows a local attacker with prior baseband firmware compromise to read sensitive information beyond intended buffer boundaries. The vulnerability does not require user interaction.

MitigationApply bounds checking in the GetCellInfoList() function to validate array indices before accessing memory. Ensure all buffer accesses are within bounds before reading cell information data.

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. Confirm the device runs Android
    Check system property 'ro.build.version.sdk' or check /system/build.prop for 'ro.build.id' containing Android identifiers
    Affected if The device is running any version of Google Android (all versions are affected)
  2. Verify cellular radio is present
    Check for /dev/smd* or /dev/radio/* device nodes, or query 'getprop' for 'gsm.version.baseband' property
    Affected if A cellular baseband radio is present and loaded (required for the vulnerability to be exploitable)
  3. Inspect baseband firmware integrity
    Compare the baseband firmware version (from 'getprop gsm.version.baseband') against known-good signatures or verify digital signatures if the device supports verified boot
    Affected if The baseband firmware has been modified or compromised (the CVE requires prior baseband firmware compromise to exploit)
  4. Check for suspicious baseband behavior
    Review kernel logs (dmesg) or baseband logs (/log/radio/) for unexpected memory access patterns or anomalies in GetCellInfoList related operations
    Affected if Abnormal cellular information retrieval patterns are observed suggesting out-of-bounds access

The environment is affected if it is a Google Android device with an active cellular radio whose baseband firmware has been compromised, enabling the out-of-bounds read in GetCellInfoList().
