There exists a TOCTOU race condition in TvSettings AppRestrictionsFragment.java that lead to start of attacker supplied activity in Settings’ context, i.e. system-uid context, thus lead to launchAnyWhere. The core idea is to utilize the time window between the check of Intent and the use to Intent to change the target component’s state, thus bypass the original security sanitize function.
The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
