CVE-2026-89448

CVE-2026-89448 is a CRITICAL (CVSS 9.3) vulnerability in the Linux kernel's Intel VT-d IOMMU subsystem. The function detect_intel_iommu() fails to check for tboot when determining whether to request ACS (Access Control Services) . When tboot is enabled, tboot_force_iommu() forces the IOMMU on, bu...

The vulnerability of the __iommu_group_set_domain_internal() function in the drivers/iommu/iommu.c file of the Linux operating system’s IOMMU driver module allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the iommugroupsetdomaininternal function in the drivers/iommu/iommu.c file of the Linux operating system’s IOMMU driver is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...

kernel: iommu/amd: Fix clone_alias() to use the original device's devid

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit AMD driver. The clonealias function incorrectly uses the device ID devid when handling alias devices. This can lead to the propagation of wrong or stale Device Table Entry DTE entries to alias devices, potentially...
