CVE-2023-21314

Published Oct 30, 2023 · Updated Aug 2, 2024

Out-of-bounds read in Android 14 Bluetooth allows local users with System privileges to read memory without user interaction. The Bluetooth component reads beyond a buffer because the required bounds check is missing before the access. System execution privileges are required, and the reported consequence is limited to local information disclosure.
