CVE-2023-20724

Local privilege escalation via unchecked Bluetooth read

Published Jun 6, 2023 · Updated Aug 2, 2024

Out-of-bounds read in MediaTek Bluetooth on MT8167, MT8175, and MT8183 with Android 11.0 through 13.0 allows local users to gain System privileges. MediaTek identifies the locus only as Bluetooth; the code reads beyond a buffer because it fails to perform a required bounds check. The path requires local access with System execution privileges and no user interaction; MediaTek has not disclosed the affected function or input boundary.
