CVE-2023-20832

Local privilege escalation via GPS bounds omission

Published Sep 4, 2023 · Updated Oct 4, 2024

Out-of-bounds write in MediaTek GPS software on Android 12.0 and 13.0 allows local users with System privileges to gain elevated privileges. The GPS component fails to check an input boundary before writing to memory, permitting data beyond the intended buffer to be overwritten. Exploitation requires local System-level execution privileges and no user interaction; the affected function and input path are undisclosed.
