**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 6.6.50 **Description** The Linux kernel library supports aggregation of objects into other objects only if the parent object does not have a parent itself, meaning nesting is not supported. Aggregation happens in two cases: without and with hints, where hints are pre-computed recommendations on how to aggregate the provided objects. The violation of the assumption that nesting cannot happen when creating objects based on hints leads to various warnings and eventually to a general protection fault. **Recommendations** Update to Linux kernel version 6.6.50 or later to resolve the issue.
