-Direct memory access (DMA) attacks can be [mitigateed](https://madaidans-insecurities.github.io/guides/linux-hardening.html#dma-attacks) via IOMMU and the previously mentioned kernel module disabling. Furthermore, [strict enforcement](https://github.com/Kicksecure/security-misc/blob/master/etc/default/grub.d/40_enable_iommu.cfg) of IOMMU TLB invalidation should be applied so devices will never be able to access stale data contents. Note that disabling the busmaster bit on all PCI bridges (`disable_early_pci_dma`) during very early boot can cause complete boot failure on certain systems if they do not have adequate resources. Therefore, as always, ensure you have a fallback option to boot into the system whenever modifying any kernel parameters.
