CVE-2026-64152

In the Linux kernel, the following vulnerability has been resolved: iommu: Handle unmap error when iommudebug is enabled Sashiko noticed a latent bug where the map error flow called iommuunmap which calls iommudebugunmapbegin/iommudebugunmapend however since this is an error path the map flow nev...

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-2026-64152

CVE-2026-64152 affects the Linux kernel iommu path. The issue arises when an unmap error in the iommu_debug flow occurs in an error path that did not establish the original iommu_debug_map, causing mis-tracing and unbalanced tracking. Fix: move the unmap error handling into iommu_map_nosync() and...

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 ...
