Summary
Instant app restriction may not be verified correctly in restorePermissionState
Details

In generatePackageInfo of PackageManagerService.java, there is a possible permissions bypass due to an incorrect permission check. This could lead to local escalation of privilege that allows instant apps access to permissions not allowed for instant apps, with no additional execution privileges needed. User interaction is not needed for exploitation.
