Local privilege escalation via keyInstall type confusion
Published Feb 5, 2024 · Updated May 9, 2025
Type confusion in keyInstall on MediaTek chipsets running Android 12.0 and 13.0 allows local users to gain elevated privileges. The component accesses a resource through an incompatible type, but MediaTek has not disclosed the specific resource, input, or code path. Exploitation requires existing System execution privileges and no user interaction; the reported consequence is further local privilege escalation.
