Local data disclosure via missing Composer bounds check
Published Oct 30, 2023 · Updated Sep 6, 2024
Out-of-bounds read in Google Android 14 Composer allows local users to disclose protected memory without additional execution privileges. Composer omits a bounds check and reads beyond an intended buffer, but Google has not published the affected function or input path. A local low-privileged process can trigger the read without user interaction, exposing data usable in privilege escalation.
