The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001077 advisory. The tracewritebackdirtypage implementation in include/trace/events/writeback.h in the Linux kernel before 4.4 improperly interacts with mm/migrate.c, which allows...

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...
