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
