Summary
In the Linux kernel, the following vulnerability has been resolved: drm/xe/vm: move xa_alloc to prevent UAF Evil user can guess the next id of the vm before the ioctl completes and then call vm destroy ioctl to trigger UAF since create ioctl is still referencing the same vm. Move the xa_alloc all the way to the end to prevent this. v2: - Rebase (cherry picked from commit dcfd3971327f3ee92765154baebbaece833d3ca9)
