CVE-2018-9408

Local memory disclosure via unchecked GPS buffers

Published Dec 4, 2024 · Updated Dec 5, 2024

Out-of-bounds reads in Android Kernel allow local users with System privileges to disclose memory through the MediaTek GPS driver. The m3326_gps_write and m3326_gps_read routines in gps.s read beyond a buffer because they omit a required bounds check. Exploitation requires local System execution privileges and no user interaction; integrity and availability impacts are not reported.
