CVE-2026-72043
A flaw was found in the Linux kernel, specifically affecting the LoongArch architecture when the hardware page table walker PTW is enabled. This vulnerability stems from a missing dirty page tracking mechanism in the ptewrprotect and pmdwrprotect functions, which can lead to incorrect handling of...

CVE-2026-72043
This CVE describes a LoongArch Linux kernel issue where hardware page table walker (PTW) could set only _PAGE_DIRTY in PTE/PMD during a write TLB miss, leaving _PAGE_MODIFIED unchanged. On fork/clone with COW, pte_wrprotect()/pmd_wrprotect() clear _PAGE_WRITE and _PAGE_DIRTY, which could lose the...

CVE-2026-53372
A flaw was found in the Linux kernel's Input/Output Memory Management Unit IOMMU subsystem. This vulnerability arises in virtualized environments when a nested domain attempts to attach to a Process Address Space ID PASID, a mechanism for devices to access memory, while its parent domain is...
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...
