Local privilege escalation via unchecked vdec write
Published Oct 7, 2024 · Updated Oct 7, 2024
Out-of-bounds write in MediaTek vdec on affected Android 12.0 devices allows local users with System access to gain higher privileges. The vdec component processes input without a required bounds check, allowing a write beyond the intended buffer. Exploitation requires prior System execution privileges and no user interaction; the vendor has not disclosed the specific input path or resulting privilege level.
