CVE-2024-20038

Local information disclosure via incorrect bounds check

Published Mar 4, 2024 · Updated Nov 19, 2024

Out-of-bounds read in MediaTek pq on affected chipsets running Android 12.0, 13.0, or 14.0 allows local users with System privileges to disclose data. The pq component applies an incorrect bounds check and reads beyond the intended buffer when processing input; MediaTek has not disclosed the specific function or input. The flaw requires existing System execution privileges, needs no user interaction, and exposes local information without a reported code-execution impact.
