Lifecycle Timeline
2DescriptionCVE.org
In Package Manager, there is a possible device lock controller bypass due to a missing permission check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Local privilege escalation in Google Android's Package Manager allows on-device attackers to bypass the device lock controller due to a missing permission check, with no user interaction required. The flaw, disclosed in the Android Security Bulletin for Android 17, carries a vendor CVSS 4.0 score of 10.0 but is described as a local escalation. No public exploit identified at time of analysis.
Technical ContextAI
Android's Package Manager (PackageManagerService) is the system component responsible for installing, querying, and managing application packages and their associated permissions. The Device Lock Controller is a system role that enforces device-management policies - typically used by enterprise mobility management or carrier financing programs to restrict device usage. A missing permission check inside the Package Manager surface allows a caller to perform an action that should be gated behind a device-lock-controller-only permission, undermining the trust boundary between unprivileged apps and the device-management subsystem. This pattern aligns with CWE-862 (Missing Authorization).
RemediationAI
Apply the Android security patch level published in the Android 17 bulletin (https://source.android.com/docs/security/bulletin/android-17) - patch available per vendor advisory; exact SPL string should be read from that bulletin and pushed through OEM/carrier OTA channels. Until the OTA reaches devices, compensating controls include restricting sideloading via MDM (Play Protect enforced, Unknown Sources disabled), monitoring for unexpected changes to device-lock-controller state through enterprise management consoles, and avoiding installation of untrusted apps on devices enrolled in device-lock programs; the trade-off is reduced flexibility for users who legitimately install non-Play-Store apps.
