In the Linux kernel, the following vulnerability has been resolved:

vp_vdpa: fix the crash in hot unplug with vp_vdpa

While unplugging the vp_vdpa device, it triggers a kernel panic The root cause is: vdpa_mgmtdev_unregister() will accesses modern devices which will cause a use after free. So need to change the sequence in vp_vdpa_remove
