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 nr modem, there is a possible system crash due to improper input validation. This could lead to remote denial of service with no additional execution privileges needed

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 in the 5G NR (New Radio) modem involves improper input validation that can be exploited remotely to cause a system crash, resulting in denial of service. The attack requires no additional execution privileges, suggesting the vulnerability is directly accessible via network-facing modem interfaces.

MitigationApply vendor-provided patches or firmware updates for the NR modem component to address the input validation flaw. If no patch is available, consider network segmentation to limit exposure of the modem interface.

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 operating system
    Check if the device runs Google Android OS. On the device, go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB.
    Affected if The device is not running Google Android OS, then it is not affected by this specific CVE.
  2. Check the Android version
    Review the installed Android version against the affected list. On the device: Settings > About Phone > Android version. Via ADB: 'adb shell getprop ro.build.version.release'
    Affected if The installed version is exactly 13.0, 14.0, 15.0, or 16.0, the device falls within the affected version range.
  3. Verify 5G NR modem is present
    Check if the device has 5G NR modem hardware and the modem is enabled. On Android: Settings > Network & Internet > Mobile Network > Preferred Network Type, or check for 5G-related settings. Via ADB: 'adb shell settings get global preferred_network_mode'
    Affected if The device lacks 5G NR modem capability or the modem is disabled, the specific attack surface for this CVE does not exist.
  4. Assess network exposure of modem interface
    Determine if the 5G NR modem interface is accessible from network-facing services. Review firewall rules: 'adb shell iptables -L' and check for exposed modem management ports. Verify if mobile network APIs or diagnostic interfaces are accessible.
    Affected if The modem interface is directly network-accessible without segmentation, the vulnerability is exploitable in the attack scenario described.

A device is affected if it runs Android 13.0, 14.0, 15.0, or 16.0 with an active 5G NR modem that has network-accessible interfaces.
