CVE-2025-39961

Summary. CVE-2025-39961 covers a race in the AMD IOMMU pgtable path where unmap may read pgtable->[root/mode] without a lock while the driver increases address space. This can lead to reading a mismatched page-table level, causing iommu_unmap to fail and upper layers to log WARN_ON. The fix, i...
