EUVD-2025-201634
In the Linux kernel, the following vulnerability has been resolved: accel/habanalabs: support mapping cb with vmalloc-backed coherent memory When IOMMU is enabled, dmaalloccoherent with GFPUSER may return addresses from the vmalloc range. If such an address is mapped without VMMIXEDMAP,...
The vulnerability in the drivers/iommu/amd/init.c component of the Linux operating system allows a attacker to compromise the integrity and accessibility of protected information.
The vulnerability in the drivers/iommu/amd/init.c component of the Linux operating system is related to the execution of operations beyond the buffer boundaries in memory. Exploiting this vulnerability allows an attacker to compromise the integrity and accessibility of the protected information...
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...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Don't call mmput from MMU notifier callback If the process is exiting, the mmput inside mmu notifier callback from compactd or fork or numa balancing could release the last reference of mm struct to call exitmmap and...
CVE-2025-40058 iommu/vt-d: Disallow dirty tracking if incoherent page walk
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Disallow dirty tracking if incoherent page walk Dirty page tracking relies on the IOMMU atomically updating the dirty bit in the paging-structure entry. For this operation to succeed, the paging- structure memory must...
