CVE-2025-21054
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 · uneditedOut-of-bounds read in the parsing header for JPEG decoding in libpadm.so prior to SMR Oct-2025 Release 1 allows local attackers to potentially access out-of-bounds memory.
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 confidenceOut-of-bounds read vulnerability in JPEG header parsing within Samsung's libpadm.so library allows local attackers to read memory beyond allocated buffers. This occurs specifically during the header parsing phase of JPEG decoding prior to SMR Oct-2025 Release 1.

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 checksWork through these to decide whether this CVE applies to you.
-
Check Android versionGo to Settings > About Phone > Android version or run 'getprop ro.build.version.release' via adb shellAffected if The version is 13.0, 14.0, 15.0, or 16.0 (Samsung variants)
-
Confirm Samsung deviceCheck that the device is a Samsung product by running 'getprop ro.product.brand' or inspecting /system/lib64/libpadm.so for presenceAffected if The device is Samsung and libpadm.so exists on the system
-
Check security patch levelRun 'getprop ro.build.version.security_patch' via adb shell to see the installed security patch dateAffected if The security patch level is earlier than 2025-10-01 (SMR Oct-2025) or the field is empty
The device is affected if it is a Samsung Android device running version 13.0, 14.0, 15.0, or 16.0, has the libpadm.so library present, and has not received the SMR Oct-2025 security update.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedApply Samsung's SMR Oct-2025 Release 1 security update which includes the patched libpadm.so library. This is a vendor-supplied binary patch; no source code remediation is available to end users.
SMR Oct-2025 Release 1 or later
- Check your Samsung device model and carrier for the availability of SMR Oct-2025 Release 1
- Navigate to Settings > Security and Privacy > Security update on your Samsung Android device
- Verify if the October 2025 security update is available
- If available, back up important data to external storage or cloud
- Apply the October 2025 security update via Settings > Security and Privacy > Security update > Download and install
- Restart the device after the update completes
- Confirm the device is running the patched version by checking Settings > Security and Privacy > Security update (date should show October 2025 or later)
