In the Linux kernel, the following vulnerability has been resolved:
drm/msm: make sure last_fence is always updated
Update last_fence in the vm-bind path instead of kernel managed path.
last_fence is used to wait for work to finish in vm_bind contexts but not
used for kernel managed contexts.
This fixes a bug where last_fence is not waited on context close leading
to faults as resources are freed while in use.
