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 &md->table_devices without any lock. If the walk races with dm_table_destroy -> free_devices -> dm_put_table_device, there is access to invalid memory.
Fix this race by extending the lock over the list walk.
