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 GetHostAddress of gxp_buffer.h, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. 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 · moderate confidence

A missing bounds check in the GetHostAddress function in gxp_buffer.h allows an out-of-bounds write operation. This memory corruption vulnerability can be exploited locally to escalate privileges without requiring additional execution privileges or user interaction.

MitigationImplement proper bounds validation before write operations in the GetHostAddress function to ensure buffer accesses stay within allocated memory limits.

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 system is running Android
    Check the OS identifier (e.g., run 'getprop ro.build.id' or check /system/build.prop)
    Affected if The system is NOT running Google Android OS
  2. Identify if the gxp_buffer.h component is present
    Search for the file gxp_buffer.h in the system firmware or kernel sources (e.g., 'find / -name gxp_buffer.h 2>/dev/null' or inspect kernel/source trees)
    Affected if The gxp_buffer.h file is NOT found in the Android system or kernel
  3. Verify the GetHostAddress function exists in gxp_buffer.h
    Open gxp_buffer.h and locate the GetHostAddress function definition to confirm it contains the bounds-check logic
    Affected if The GetHostAddress function is NOT present or has already been patched with bounds validation
  4. Check if the affected code path is in use
    Determine if any driver, service, or component on the device calls GetHostAddress from gxp_buffer.h (e.g., via binary analysis or log inspection)
    Affected if The GetHostAddress function exists but is NOT actively called by any component on the device

A user is affected if the system runs Google Android AND contains the gxp_buffer.h component with a vulnerable GetHostAddress function that lacks proper bounds checking before write operations.
