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 an incorrect 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 buffer overflow vulnerability exists in the GetHostAddress function within gxp_buffer.h due to an incorrect bounds check, allowing an out-of-bounds write. This flaw enables local privilege escalation without requiring additional execution privileges or user interaction.

MitigationApply a patch or update that corrects the bounds checking logic in GetHostAddress to properly validate buffer limits before writing 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 is running Android
    Check the OS by examining /system/build.prop or running 'getprop ro.build.id' or 'uname -a' to verify the kernel/OS is Android-based
    Affected if The device runs any version of Android OS - the advisory states all Android versions are affected
  2. Identify the presence of the vulnerable gxp_buffer.h component
    Search for files named gxp_buffer.h or related libraries containing 'GetHostAddress' function on the device filesystem, typically in system/lib or vendor/lib directories
    Affected if The gxp_buffer.h header file or compiled library containing GetHostAddress exists on the device
  3. Verify the GetHostAddress function implementation
    If the component is found, examine the bounds checking logic in the GetHostAddress function for the known incorrect bounds check that allows out-of-bounds writes
    Affected if The function contains the flawed bounds check that permits writing beyond buffer limits

If the device runs Android and contains the gxp_buffer.h component with the GetHostAddress function, it is likely affected since all Android versions are impacted by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation

Apply a patch or update that corrects the bounds checking logic in GetHostAddress to properly validate buffer limits before writing data.

Recommended fix Moderate confidence

Latest Android security patch level (check source.android.com/security/bulletin for specific monthly release containing the fix)

  1. Check your device's current Android version and security patch level in Settings > About Phone > Security Patch Level
  2. Verify if your device manufacturer has released a security update addressing this vulnerability (CVE-2025-36928)
  3. If an update is available, back up important data before proceeding
  4. Install the latest available security patch update for your device
  5. After updating, verify the new security patch level reflects the latest available update
Caveat Security updates are generally backward compatible; minimal risk of breaking changes from monthly patches
