CVE-2024-20055

Local information disclosure via missing bounds check

Published Apr 1, 2024 · Updated Mar 26, 2025

Information disclosure in MediaTek imgsys on Android 12.0, Android 13.0, Yocto 4.0, and IOT-v23.2 allows local users to read out-of-bounds data. The imgsys component reads beyond an intended buffer boundary because it fails to validate an unspecified input length or index. Exploitation requires existing System execution privileges and user interaction, and the disclosed data is not further characterized.
