CVE-2024-20129Network attack vector

Remote service interruption via unchecked Telephony read

Published Dec 2, 2024 · Updated Mar 13, 2025

Out-of-bounds read in MediaTek Telephony on affected chipsets running Android 13.0 through 15.0 allows remote attackers to interrupt service. The Telephony component reads beyond an intended buffer because the relevant read lacks a required bounds check; MediaTek has not disclosed the file, function, or input field. No privileges or user interaction are required, and the documented consequence is denial of service rather than data disclosure or code execution.
