Local denial of service via skipped policy persistence
Published Aug 15, 2024 · Updated Nov 25, 2024
Denial of service in Android 14 Framework allows local users to interrupt device management by preventing MDM policy persistence. OwnersData.DeviceOwnerReadWriter.shouldWrite evaluates false when other owner-data fields remain, causing writeToFileLocked to skip serialization and delete device_owner_2.xml instead of preserving the policy data. Local access is required; no additional execution privileges or user interaction are needed, and loss of persisted MDM policy state disrupts managed-device operation.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
