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...

CVE-2026-64149

In the Linux kernel, the following vulnerability has been resolved: dma-mapping: move dmamapresource sanity check into debug code dmamapresource uses pfnvalid to ensure the range is not RAM. However, pfnvalid only checks for availability of the memory map for a PFN but it does not ensure that the...

CVE-2026-64149

In the Linux kernel, CVE-2026-64149 fixes a DMA mapping sanity check: dma_map_resource() previously relied on pfn_valid() to exclude RAM, but this could misclassify MMIO regions sharing a sparsemem section as usable RAM, triggering a WARN_ON_ONCE and DMA_MAPPING_ERROR on platforms like Raspberry ...

CVE-2026-64130

CVE-2026-64130 concerns the Linux kernel’s memory-tagging handling in mm/page_alloc for the huge zero folio when init_on_free is enabled. The root cause was that __GFP_ZEROTAGS could skip clearing tag memory while __GFP_ZERO and __GFP_SKIP_KASAN were set, leaving leftover MTE tags on pages mapped...

EUVD-2026-45815

In the Linux kernel, the following vulnerability has been resolved: mm/pagealloc: fix initialization of tags of the huge zero folio with initonfree GFPZEROTAGS semantics are currently a bit weird, but effectively this flag is only ever set alongside GFPZERO and GFPSKIPKASAN. If we run with...

CVE-2026-64129 mm/migrate_device: fix spinlock leak in migrate_vma_insert_huge_pmd_page

In the Linux kernel, the following vulnerability has been resolved: mm/migratedevice: fix spinlock leak in migratevmainserthugepmdpage When checkstableaddressspace fails after the PMD spinlock has been acquired via pmdlock, the code jumps directly to the abort label, bypassing the spinunlock call...

CVE-2026-64129

The CVE-2026-64129 entry concerns the Linux kernel vulnerability in mm/migrate_device: migrate_vma_insert_huge_pmd_page where a check_stable_address_space() failure after acquiring the PMD spinlock via pmd_lock() could jump to abort, bypassing spin_unlock() in unlock_abort. This caused the PMD sp...
