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 onHeaderDecoded of LocalImageResolver.java, there is a possible persistent denial of service due to resource exhaustion. This could lead to remote denial of service 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 denial of service vulnerability exists in the onHeaderDecoded method of LocalImageResolver.java where processing of image headers can cause resource exhaustion. The vulnerability allows remote attackers to cause a persistent DoS condition without requiring any privileges or user interaction.

MitigationImplement resource limits and bounds checking on image header decoding operations to prevent resource exhaustion. Consider adding maximum size limits and timeout controls for image processing.

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. Check Android OS version
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell
    Affected if Version is 13.0, 14.0, 15.0, or 16.0 exactly
  2. Verify LocalImageResolver component presence
    Search system apps or framework jars for 'LocalImageResolver' class - inspect /system/framework or app directories for files containing 'LocalImageResolver.java' or compiled .class/.dex equivalents
    Affected if The LocalImageResolver component is present and loaded by the system
  3. Confirm image header processing is active
    Monitor app process using image decoding - check if any installed app or system service invokes image loading that routes through LocalImageResolver's onHeaderDecoded method
    Affected if Any application or service performs image header decoding operations on the device
  4. Check for resource exhaustion indicators
    Review logcat for patterns like 'EOMError', 'OutOfMemory', or image decoding failures - filter for 'LocalImageResolver' or 'onHeaderDecoded' tags
    Affected if Repeated image decode failures or memory errors occur during image header processing

A device is affected if it runs Android 13.0, 14.0, 15.0, or 16.0 and has the LocalImageResolver component present with active image header decoding functionality.
