he vulnerability is to delete arbitrary files in LGInstallService (com.lge.lginstallservies) app. The app contains the exported com.lge.lginstallservies.InstallService service that exposes an AIDL interface. All its installPackage* methods are finally calling the installPackageVerify() method that performs signature validation after the delete file method. An attacker can control conditions so this security check is never performed and an attacker-controlled file is deleted.
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.
