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.

No CVSS v4.0

No CVSS v3.1
