CVE-2026-64186

The CVE concerns the Linux kernel AMD IOMMU debugfs path. The vulnerability stems from using int-typed dbg_mmio_offset and dbg_cap_offset populated via kstrtou32_from_user(), which can wrap to a negative value for large inputs and enable out-of-bounds reads in iommu_mmio_write() and iommu_capabil...

CVE-2026-64153

The CVE concerns the Linux kernel DRM MSM IOMMU path. The issue was in iommu_map_sgtable() returning a size_t and 0 on error; it now returns an ssize_t and propagates negative error codes. The commit change (iommu: return full error code from iommu_map_sg_atomic ) stores the error value in the pr...

CVE-2026-64152

The CVE describes a Linux kernel IOMMU issue: when iommu_debug is enabled, an error path calling iommu_unmap() could lead to an unbalanced trace because the map was never established. The remediation reorganizes the flow by moving unmap error handling into iommu_map_nosync() and recording the par...

CVE-2026-64071

The CVE-2026-64071 issue is a use-after-free in the Linux kernel nvme-pci path. In nvme_free_host_mem(), dev->hmb_sgt is freed via dma_free_noncontiguous() but the pointer is not cleared, so a second call in the nvme_probe() error path (nvme_setup_host_mem() succeeds, nvme_set_host_mem() fails...
