Local memory disclosure via missing vdec bounds check
Published Oct 7, 2024 · Updated Oct 27, 2024
Out-of-bounds read in MediaTek vdec on Android 12.0 allows local users with System privileges to disclose memory without user interaction. The vdec component reads beyond a buffer because a required bounds check is missing; MediaTek has not disclosed the affected function, buffer, or input. Exploitation requires prior System-level execution and exposes memory contents without altering data or interrupting service.
