CVE-2022-30719
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 · uneditedImproper input validation check logic vulnerability in libsmkvextractor prior to SMR Jun-2022 Release 1 allows attackers to trigger crash.
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 confidenceImproper input validation in libsmkvextractor allows attackers to cause a denial-of-service crash by providing malformed input. The vulnerability stems from insufficient validation checks in the library's parsing logic prior to the SMR Jun-2022 Release 1 patch.

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 OS versionGo to Settings > About Phone > Android version and note the exact version number shownAffected if The version is exactly 10.0, 11.0, or 12.0
-
Identify apps using libsmkvextractorReview installed media player or video editing applications that handle SMKV or MKV video files; check application permissions for media accessAffected if An application that processes video files is installed and processes untrusted media content
-
Verify library presenceOn a rooted device, check /system/lib/libsmkvextractor.so or /system/lib64/libsmkvextractor.so for the library file; for developers, inspect app dependencies for this libraryAffected if The libsmkvextractor library exists in the system and is used by installed applications
-
Check system patch levelGo to Settings > About Phone > Android version > Security patch level and note the dateAffected if The security patch level is earlier than the SMR Jun-2022 Release 1 update
You are affected if your Android device runs version 10.0, 11.0, or 12.0 with a security patch level before Jun-2022 and you use applications that process video files via libsmkvextractor.
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 · scopedUpdate libsmkvextractor to SMR Jun-2022 Release 1 or later to obtain the patched version with proper input validation. If update is not immediately possible, implement input filtering at the application layer to reject malformed data before passing it to the library.
SMR Jun-2022 Release 1 (June 2022 Security Patch Level)
- Go to Settings on your Samsung device
- Tap on Software update
- Tap on Download and install to check for available updates
- Ensure you update to the June 2022 Security Patch Level (SMR Jun-2022 Release 1) or later
- After installation, verify the security patch level by going to Settings > About phone > Software information > Security patch level
