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
A heap-based overflow vulnerability in ConstructDictionary function in libSDKRecognitionText.spensdk.samsung.so library prior to SMR Sep-2022 Release 1 allows attacker to cause memory access fault.

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 heap-based buffer overflow in the ConstructDictionary function of Samsung's S Pen SDK library (libSDKRecognitionText.spensdk.samsung.so) on devices prior to SMR Sep-2022 Release 1 allows an attacker to overflow a heap buffer, causing memory corruption and potentially achieving arbitrary code execution.

MitigationApply the Samsung SMR Sep-2022 Release 1 or later security update to affected devices to patch the vulnerable ConstructDictionary function in the S Pen SDK library.

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 the Android version
    Go to Settings > About Phone > Android version or run 'getprop ro.build.version.sdk' via ADB
    Affected if The version is 10, 11, or 12 (these are the affected Android versions listed)
  2. Verify the S Pen SDK library is present
    Look for the library file 'libSDKRecognitionText.spensdk.samsung.so' on the device, typically in /system/lib or /vendor/lib directories
    Affected if The library file exists on the device - this confirms the vulnerable component is installed
  3. Check the security patch level
    Go to Settings > About Phone > Security patch level or run 'getprop ro.build.version.security_patch' via ADB
    Affected if The security patch level is earlier than September 2022 (SMR Sep-2022 Release 1 is the patched version)

The device is affected if it runs Android 10, 11, or 12, has the S Pen SDK library installed, and has a security patch level before September 2022.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the Samsung SMR Sep-2022 Release 1 or later security update to affected devices to patch the vulnerable ConstructDictionary function in the S Pen SDK library.

Recommended fix High confidence

SMR Sep-2022 Release 1 (September 2022 Security Patch Level)

  1. Go to Settings on the Samsung device
  2. Navigate to System > System Update or Settings > About Phone > Software Update
  3. Check for available updates and download the September 2022 security update (SMR Sep-2022 Release 1) or later
  4. Install the update and restart the device
  5. Verify the security patch level is September 2022 or later by going to Settings > About Phone > Software Information > Security patch level
Caveat Users should ensure they back up important data before applying system updates, though security updates typically have minimal risk
