CVE-2026-64151

The CVE-2026-64151 entry concerns the Linux kernel iommupt component, where a driver could omit PAGE_SIZE from the pgsize_bitmap. The root cause is that removing PAGE_SIZE from the bitmap is technically allowed but would leave an iommu_domain unused with the DMA API; the design is violated. The d...
