CVE-2022-36863
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 · uneditedA heap-based overflow vulnerability in GetCorrectDbLanguageTypeEsPKc 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 · high confidenceHeap-based buffer overflow in the GetCorrectDbLanguageTypeEsPKc function within Samsung's libSDKRecognitionText.spensdk.samsung.so library. The overflow allows an attacker to write beyond allocated heap memory boundaries, causing memory access faults. This exists in S Pen recognition functionality on Samsung devices prior to the September 2022 security update.

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.
-
Confirm device is a Samsung modelCheck the device manufacturer via 'getprop ro.product.manufacturer' or 'getprop ro.build.brand' command in ADB shellAffected if The manufacturer/brand is not Samsung (this vulnerability is specific to Samsung devices)
-
Verify Android version is affectedRun 'getprop ro.build.version.release' in ADB shell to check the Android versionAffected if Version is 10, 11, or 12 (versions outside this range are not affected)
-
Check for presence of vulnerable S Pen librarySearch for the library file using 'find / -name "libSDKRecognitionText.spensdk.samsung.so" 2>/dev/null' in ADB shellAffected if The library file exists on the device (indicating S Pen recognition component is present)
-
Verify security patch level is pre-September 2022Run 'getprop ro.build.version.security_patch' in ADB shell to check the security patch dateAffected if Patch level is earlier than 2022-09-01 (vulnerability exists in versions before Samsung's Sep-2022 SMR)
A Samsung device on Android 10, 11, or 12 with the libSDKRecognitionText library present and a security patch level before September 2022 is likely affected by this heap-based buffer overflow in the S Pen recognition functionality.

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 the SMR Sep-2022 Release 1 or later security patch from Samsung, which updates the libSDKRecognitionText library to address the heap overflow vulnerability.
Samsung SMR Sep-2022 Release 1 (Security Patch Level September 2022)
- Check your Samsung device for system updates
- Navigate to Settings > Software update > Download and install
- Ensure the device updates to SMR Sep-2022 Release 1 or later (Security Patch Level September 2022 or higher)
- Verify the update was applied by checking Settings > About phone > Software information > Security patch level
