Sumário

de MITRE • 11/09/2026

In the Linux kernel, the following vulnerability has been resolved:

iommu/vt-d: Force requesting ACS when tboot is enabled

Currently the conditions of requesting ACS in detect_intel_iommu() don't include tboot, leading to a possible misconfiguration with ACS disabled (e.g. due to user opts) while iommu is later forced on by tboot_force_iommu().

Fix it by checking tboot in detect_intel_iommu().
