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 gnss service, there is a possible out of bounds write due to improper input validation. This could lead to local esclation of privileges with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS08017365; Issue ID: ALPS08017365.

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 local privilege escalation vulnerability exists in the gnss (GPS) service where improper input validation allows an attacker to write data beyond allocated buffer boundaries. Successful exploitation grants System-level execution privileges without requiring user interaction.

MitigationApply vendor patch ALPS08017365 which addresses input validation in the gnss service to prevent out-of-bounds writes. This is a system-level service vulnerability requiring System privileges for exploitation.

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 your Linuxfoundation Yocto version
    Check the /etc/os-release or run 'cat /etc/yocto-release' or check the build configuration
    Affected if Version is exactly 2.6 (not later)
  2. Identify your Google Android version
    Go to Settings > About Phone > Android version or run 'getprop ro.build.version.release'
    Affected if Version is exactly 13.0 (not later)
  3. Identify your OpenWRT version
    Run 'cat /etc/openwrt_version' or check /etc/os-release
    Affected if Version is exactly 19.07.0 or exactly 21.02.0 (not later)
  4. Verify gnss service presence
    Check if gnss or gps service daemon is running - run 'ps | grep -i gnss' or 'ps | grep -i gps' on Android, or check /etc/init.d/ for gnss-related services on embedded systems
    Affected if A gnss/gps service daemon is running on the device

You are affected only if you are running Yocto 2.6, Android 13.0, or OpenWRT 19.07.0/21.02.0 AND the gnss service is present on the system.
