Local privilege escalation via stc race condition
Published Sep 4, 2023 · Updated Oct 1, 2024
Out-of-bounds read in MediaTek MT8188 stc on Android 11.0 and 13.0 allows local users to gain elevated privileges. A race condition in stc permits a buffer read outside its intended bounds, but MediaTek has not disclosed the raced operation or affected code path. Exploitation requires existing System execution privileges, high-complexity race timing, and user interaction; the resulting elevated privilege level is not specified.
