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

release and unlock allocated system pages. To do that driver should use page

physical address, or pfn, then get struct page*. Current driver uses dma

address(for adev) that is not correct with IOMMU enabled, or even in general.

The patch releases and unlocks allocated system pages based on where migration

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

ram pages at error path. (NVD)

Monitor Linux's web page for any future patch releases.
