Local privilege escalation via missing display bounds check
Published Jan 6, 2026 · Updated Jan 6, 2026
Out-of-bounds write in MediaTek Display Driver on Android 14.0, 15.0, and 16.0 allows local users with System privilege to escalate access. The display component writes beyond a buffer because the operation lacks a bounds check; MediaTek has not disclosed a finer code locus. Exploitation requires existing System privilege and no user interaction, and the vendor does not identify the higher privilege obtained.
