vduse: hold vduse_lock across IDR lookup in open path
In the Linux kernel, the following vulnerability has been resolved: vduse: hold vduse_lock across IDR lookup in open path vduse_dev_open() looks up struct vduse_dev through the IDR and then acquires dev->lock only after vduse_lock has been dropped. This leaves a window where a concurrent VDUSE_DESTROY_DEV can remove the same object from the IDR and free it before the open path locks the device, leading to a use-after-free. Close this race by keeping vduse_lock held until dev->lock has been acquired in the open path, matching the lock ordering already used by the destroy path.
