CVE-2024-20878
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 · uneditedHeap out-of-bound write vulnerability in parsing grid image in libsavscmn.so prior to SMR June-2024 Release 1 allows local attackers to execute arbitrary code.
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 confidenceHeap-based buffer overflow vulnerability in the grid image parsing functionality of libsavscmn.so allows local attackers to write beyond allocated heap boundaries, potentially achieving arbitrary code execution. The vulnerability exists in the image parsing logic prior to the SMR June-2024 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.
-
Verify Samsung Android versionRun 'getprop ro.build.version.release' to check if the device is running Android 12.0, 13.0, or 14.0Affected if Device is running Android 12.0, 13.0, or 14.0 on a Samsung device
-
Confirm libsavscmn.so presenceSearch for the library file on the device using 'find / -name libsavscmn.so 2>/dev/null' or check common system library pathsAffected if libsavscmn.so exists on the device
-
Check SMR patch levelRun 'getprop ro.build.version.sem' or 'getprop ro.sem.platform.version.time' to identify the Samsung Mobile Release version and dateAffected if SMR version is earlier than the June-2024 Release 1 patch (SMR Jun-2024 or earlier)
-
Identify grid image parsing usageMonitor application logs or network traffic for grid image processing features that invoke libsavscmn.so image parsing functionsAffected if Grid image parsing features are actively used on the device
Device is affected if running Samsung Android 12.0/13.0/14.0 with a pre-June-2024 SMR version and the vulnerable libsavscmn.so library present while using grid image parsing 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 June-2024 Release 1 update or later to obtain the patched version of libsavscmn.so, then verify that grid image parsing functionality operates correctly without memory corruption.
Samsung SMR June-2024 Release 1 (or later security maintenance release)
- Open Settings on the Samsung Galaxy device
- Navigate to Software update
- Tap Download and install to check for the June-2024 SMR (Security Maintenance Release) update
- If available, download and install the update containing the June-2024 security patch
- After installation, verify the device is running June-2024 SMR Release 1 or later in Settings > About phone > Software information > Security patch level
