CVE-2023-54230

Resource leak via missing device-tree node release

Published Dec 30, 2025 · Updated Dec 30, 2025

A reference leak in the Linux kernel beginning with 3.1 allows attackers to retain device-tree node references during AMBA device teardown. The amba_device_release function fails to call of_node_put after device-tree creation increments the node reference count. The public advisory identifies no attacker-controlled trigger or demonstrated service interruption, leaving reachability and operational impact undisclosed.
