CVE-2024-35879

Kernel memory leak via asynchronous OF teardown

Published May 19, 2024 · Updated Aug 5, 2026

Memory leak in the dynamic device-tree code of the Linux kernel allows local users to retain kernel memory during overlay removal. of_changeset_destroy() can destroy OF nodes before an asynchronous devlink-removal job releases its device and of_node reference, causing of_node_put() to run after node destruction. Reachability requires platform-device depopulation followed by overlay removal; the documented consequence is a refcount warning and unreleased kernel memory.
