  "details": "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-\u003elock 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-\u003elock has been acquired in the open path, matching the lock ordering already used by the destroy path.",
