  "details": "In the Linux kernel, the following vulnerability has been resolved:  dm: fix race when loading and unloading a table  If the userspace calls two concurrent table load ioctls and one of them succeeds and the other fails, there is a race condition because dm_setup_md_queue walks \u0026md-\u003etable_devices without any lock. If the walk races with dm_table_destroy -\u003e free_devices -\u003e dm_put_table_device, there is access to invalid memory.  Fix this race by extending the lock over the list walk.",
