漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:drm/virtio: Fix GEM handle creation UAFUserspace can guess the handle value and try to race GEM object creationwith handle close, resulting in a use-after-free if we dereference theobject after dropping the handle s reference. For that reason, droppingthe handle s reference must be done after we are done dereferencingthe object.

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

drm/virtio: Fix GEM handle creation UAF

Userspace can guess the handle value and try to race GEM object creation
with handle close, resulting in a use-after-free if we dereference the
object after dropping the handle's reference. For that reason, dropping
the handle's reference must be done after we are done dereferencing
the object.

The Linux kernel CVE team has assigned CVE-2022-48899 to this issue.
