CVE-2024-34678
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 write in libsapeextractor.so prior to SMR Nov-2024 Release 1 allows local attackers to cause memory corruption.
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 confidenceAn out-of-bounds write vulnerability exists in libsapeextractor.so in Samsung mobile devices prior to the November 2024 SMR update. The flaw allows a local attacker to write data beyond allocated buffer boundaries, causing memory corruption.

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 mobile deviceCheck the device manufacturer via Settings > About Phone > Manufacturer or run 'getprop ro.product.manufacturer' in ADB shellAffected if Manufacturer is not Samsung - the vulnerability only affects Samsung mobile devices
-
Check Android versionNavigate to Settings > About Phone > Android version or run 'getprop ro.build.version.release' in ADB shellAffected if Version is 12.0, 13.0, or 14.0 - these are the affected versions listed in the SMR update
-
Verify libsapeextractor.so is presentCheck for the existence of the library at /system/lib/libsapextractor.so or /system/lib64/libsapextractor.so using ADB: 'ls -la /system/lib*/libsapextractor.so'Affected if The library exists on the device - this is the vulnerable component where the out-of-bounds write occurs
-
Check SMR patch levelRun 'getprop ro.build.version.sem' in ADB shell to retrieve the Samsung Mobile Renderer patch level, or check Security patch level in Settings > About Phone > Software informationAffected if Patch level is earlier than November 2024 Release 1 - the vulnerability was addressed in the Nov-2024 SMR update
A Samsung mobile device running Android 12.0, 13.0, or 14.0 with libsapeextractor.so present and a patch level before November 2024 is affected by this vulnerability.

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 Nov-2024 Release 1 or later patch which addresses the libsapeextractor.so vulnerability.
SMR Nov-2024 Release 1 (or later security maintenance release)
- Check for system updates on the Samsung Galaxy device by navigating to Settings > Software Update > Download and install
- Ensure the device is connected to Wi-Fi and has sufficient battery (at least 50%)
- Download and install the SMR (Samsung Maintenance Release) Nov-2024 or later
- After installation, verify the device has the November 2024 security patch by going to Settings > About phone > Software information > Security patch level
- Confirm the libsapextractor.so component has been updated as part of this security release
