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 Pixel cellular firmware, there is a possible out of bounds write due to a missing bounds check. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-240662453References: N/A

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

Out-of-bounds write vulnerability in Pixel cellular (baseband/modem) firmware due to a missing bounds check. This allows remote code execution with no required privileges or user interaction, making it highly exploitable.

MitigationApply vendor firmware updates from Google/Pixel as they become available; until then, consider network segmentation to limit exposure of affected devices.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 device type
    Identify if the target device is a Google Pixel phone or other Android device with cellular baseband/modem firmware. Use 'Settings > About Phone' or check /sys/class/boot_info for device model.
    Affected if Device is a Google Pixel or Android phone with baseband/modem hardware and all Android versions are affected
  2. Verify baseband module is present
    Check for baseband/modem firmware presence by examining /proc/version, /sys/class/boeffla-wl, or using 'getprop' commands like 'getprop ro.baseband' or 'getprop gsm.version.baseband'.
    Affected if Baseband/modem firmware is present on the device (which is the case for most Android phones)
  3. Check cellular connectivity is enabled
    Confirm the device has cellular radio enabled. Check via 'Settings > Network & Internet > SIM cards' or run 'settings get global mobile_data' or check /sys/class/net/ for cellular interfaces like rmnet0, ccmni0.
    Affected if Cellular radio and baseband firmware are actively in use on the device
  4. Confirm Android version
    Run 'getprop ro.build.version.release' or check 'Settings > About Phone > Android version'. All Android versions are affected per the CVE.
    Affected if Device runs any version of Android - all versions are within scope

If the device is any Google Pixel or Android phone with active cellular/baseband firmware, it is affected by this vulnerability.
