Out-of-bounds write in Samsung Electronics libsavscmn.so before Android 15 allows local attackers to corrupt process memory. Samsung has not disclosed the affected function, input format, or missing validation that permits data to be written beyond its intended buffer. A local foothold is required, and the published consequence is limited to memory corruption rather than code execution.
