Local code execution via codec out-of-bounds write
Published Aug 7, 2024 · Updated Aug 7, 2024
Out-of-bounds write in Samsung Mobile Devices on Android 12 through 14 allows local users to execute arbitrary code in the media codec. The libcodec2secmp4vdec.so library processes insufficiently validated local input and writes beyond an allocated memory boundary; Samsung has not disclosed the affected function or input format. Exploitation requires local access, and public details do not establish the caller’s privilege context or the specific input path.
