CVE-2026-45945

A flaw was found in the Linux kernel's Intel VT-d Virtualization Technology for Directed I/O implementation. A race condition occurs during the replacement of an active PASID Process Address Space ID entry. This can lead to the IOMMU Input/Output Memory Management Unit hardware reading an...

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...

iommu/vt-d: Use device rbtree in iopf reporting path

...

The vulnerability of the iommu/vt-d component in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the iommu/vt-d component in the Linux operating system’s kernel is related to excessive resource consumption during the loop. Exploiting this vulnerability can allow an attacker to cause a service failure...

kernel: iommu/vt-d: Clean up si_domain in the init_dmars() error path

A memory leak flaw was found in the Linux kernel's Intel VT-d IOMMU driver in the initialization error path. A local user can trigger this issue when the initdmars function fails during IOMMU setup, causing the sidomain memory to remain allocated without being freed. This results in a permanent...

SUSE CVE-2013-1952

Xen 4.x, when using Intel VT-d for a bus mastering capable PCI device, does not properly check the source when accessing a bridge device's interrupt remapping table entries for MSI interrupts, which allows local guest domains to cause a denial of service interrupt injection via unspecified vector...

hw: vt-d related privilege escalation

A flaw was found in Intel® VT-d products. Entries from the context cache on some types of context cache invalidations may not be properly invalidated which may allow an authenticated user to potentially enable escalation of privilege via local access. The highest threat from this vulnerability is...

The highest threat from this vulnerability is...

The vulnerability of the Intel Virtualization Technology for Directed I/O (VT-d) implementation arises due to incomplete cleanup of temporary or auxiliary resources, allowing attackers to exploit their privileges.

The vulnerability of the Intel Virtualization Technology for Directed I/O VT-d implementation exists due to incomplete cleanup of temporary or auxiliary resources. Exploiting this vulnerability can allow attackers to enhance their privileges...
