CVE-2024-20081

Local privilege escalation via GNSS buffer overwrite

Published Jul 1, 2024 · Updated Mar 13, 2025

Out-of-bounds write in MediaTek's GNSS service on affected chipsets and software allows local users to gain elevated privileges. The service inadequately validates input before writing it to a memory buffer, permitting a write past the allocated bounds; the exact function is undisclosed. Exploitation requires existing System execution privileges, needs no user interaction, and can execute code with greater local authority.
