CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of the sparx5 switchdev blocking notifier during initialization failures. If the workqueue allocation fails, the blocking notifier remains registered, potentially leading to improper resource management and system instability. Linux kernel maintainers and developers working with networking components should prioritize addressing this issue to ensure system reliability and prevent potential exploitation.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: net: sparx5: unregister blocking notifier on init failure sparx5_register_notifier_blocks() registers the switchdev blocking notifier before allocating the ordered workqueue. If the workqueue allocation fails, the error path unregisters the switchdev and netdevice notifiers, but leaves the blocking notifier registered. Add a separate error label for the workqueue allocation failure path and unregister the switchdev blocking notifier there.
