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...

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Fix missing dirty page tracking in pte,pmdwrprotect When hardware page table walker PTW is enabled on LoongArch, the CPU may set PAGEDIRTY directly in the page table entry during a write TLB miss, without going through...
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...

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Fix missing dirty page tracking in pte,pmd wrprotect When hardware page table walker PTW is enabled on LoongArch, the CPU may set PAGE DIRTY directly in the page table entry during a write TLB miss, without going throu...
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 5.10
In the Linux kernel, the following vulnerability has been resolved: KVM: x86 – Handling of SRCU initialization failures during page track initialization Check the return value of initsrcustruct, which may fail due to OOM conditions when initializing the page track mechanism. Lack of checking lead...
Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-007595)
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-007595 advisory. In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Handle SRCU initialization failure during page track init Check the return of...
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...
