Description
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix error path at svm_migrate_copy_to_ram
If page migration from device to sys ram fails for some reasons driver needs

failed by struct page* of sys ram pages. Also dma_unmap correspodent system
ram pages at error path.
