CVE-2025-40293 iommufd: Don't overflow during division for dirty tracking

In the Linux kernel, the following vulnerability has been resolved: iommufd: Don't overflow during division for dirty tracking If pgshift is 63 then BITSPERTYPEbitmap-bitmap pgsize will overflow to 0 and this triggers divide by 0. In this case the index should just be 0, so reorganize things to...

CVE-2025-40293

CVE-2025-40293 : Linux kernel iommufd had a division-by-zero risk when calculating dirty-tracking bitmap indices if pgshift == 63, caused by an overflow in computing BITS_PER_TYPE(*bitmap->bitmap) * pgsize. The fix reorganizes the division to divide by shift instead of overflowing, preventing ...

kernel: iommu/vt-d: Disallow dirty tracking if incoherent page walk

A flaw was found in the Intel VT-d IOMMU support in the Linux kernel. When an IOMMU is configured to perform dirty-page tracking, but the page-walk memory region is incoherent between the IOMMU and CPU, the hardware may attempt to atomically update the bits in a paging-structure entry that is not...
