Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Disallows dirty tracking if the page walk is incoherent. Dirty page tracking relies on the IOMMU to atomically update the dirty bit in the paging-structure entry. For this operation to succeed, the paging-structure...

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...

CVE-2025-40058

CVE-2025-40058 is a Linux kernel vulnerability affecting the iommu/vt-d path. The issue arises when the IOMMU page walk is incoherent, causing dirty page tracking to fail because the IOMMU and CPU cannot atomically update the dirty bit in the paging-structure entry. The mitigation described in th...
