- Summary
- CVE-2026-89448 affecting package kernel 6.6.150.1-1
- Details
-
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().
