CVE-2024-20146

Adjacent code execution via WLAN bounds error

Published Jan 6, 2025 · Updated Feb 26, 2026

Out-of-bounds write in MediaTek WLAN STA drivers allows physically proximate attackers to execute code without authentication. The driver improperly validates WLAN input before performing a write beyond destination bounds across affected Android, SDK, OpenWrt, and Yocto releases. Exploitation requires adjacent wireless reachability but no privileges or user interaction, and successful exploitation executes code in the driver's context.
