In the Linux kernel, the following vulnerability has been resolved:
iommu/dma: Check atomic pool allocation result directly
The non-blocking, non-coherent allocation path uses dma_alloc_from_pool(),
which returns the allocated page and fills cpu_addr only on success.
Do not rely on cpu_addr to detect allocation failure in this path. Check
the returned page directly before using it for the IOMMU mapping.
