CVE-2024-20143

Local privilege escalation via unchecked buffer write

Published Jan 6, 2025 · Updated Jan 6, 2025

Out-of-bounds write in MediaTek V6 DA allows physically proximate attackers to gain elevated local privileges through user interaction. The DA component omits a bounds check and writes beyond the intended buffer while processing an undisclosed input. Physical possession and user interaction are required, but no prior execution privileges are needed; exploitation elevates local privileges.
