Local privilege escalation via incorrect display bounds check
Published Dec 4, 2023 · Updated Aug 2, 2024
Out-of-bounds read in MediaTek display software for Android 12.0 and 13.0 allows local users to gain elevated privileges. The display component applies an incorrect bounds check before a memory read, allowing the read to cross the intended buffer boundary; the affected function and input path are undisclosed. Exploitation requires local System execution privileges and no user interaction, and the consequence is privilege escalation on listed MediaTek chipsets.
