Description OSIDB Bzimport 2024-12-29 09:01:42 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ionic: Fix netdev notifier unregister on failure

If register_netdev() fails, then the driver leaks the netdev notifier.
Fix this by calling ionic_lif_unregister() on register_netdev()
failure. This will also call ionic_lif_unregister_phc() if it has
already been registered.
