[PATCH 0/3] [PULL REQUEST] iommu/vt-d: Fixes for v7.1-rc

From: Lu Baolu

Date: Fri May 08 2026 - 22:46:20 EST


Hi Joerg,

The following fixes have been queued for v7.1-rc. They aim to fix the
following issues.

- Apply an existing quirk for Q35 graphic device.
- Skip dev_pasid teardown for the blocked domain to avoid out-of-bounds
access.
- Return early if dev_pasid is missing to prevent NULL dereference or
UAF.

These patches have been reviewed and tested and are ready for merge.
Please consider them for iommu/fix branch.

Best regards,
baolu
