Details

In isRequestPinItemSupported of ShortcutService.java, there is a possible cross-user leak of packages in which the default launcher supports requests to create pinned shortcuts due to a permissions bypass. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.
