Local privilege escalation via permission squatting

Permission squatting in Google Cloud Android 14 and 15 allows local users to gain elevated privileges through RoleService without user interaction. RoleService's getDefaultApplicationAsUser and setDefaultApplicationAsUser methods check MANAGE_DEFAULT_APPLICATIONS without rejecting platforms where that permission is undefined, allowing a malicious app to define and acquire the permission first. Local app execution is sufficient; no additional execution privileges or user interaction is required, and the consequence is limited to local privilege escalation.
