In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix lockdep assertion on sync reset unload event Fix lockdep assertion triggered during sync reset unload event. When the sync reset flow is initiated using the devlink reload fw_activate option, the PF already holds the devlink lock while handling unload event. In this case, delegate sync reset unload event handling back to the devlink callback process to avoid double-locking and resolve the lockdep warning.
