Technical Description
In the Linux kernel, the following vulnerability has been resolved:
vdpa: fix use-after-free on vp_vdpa_remove
When vp_vdpa driver is unbind, vp_vdpa is freed in vdpa_unregister_device
and then vp_vdpa->mdev.pci_dev is dereferenced in vp_modern_remove,
triggering use-after-free.
