Description OSIDB Bzimport 2026-07-19 10:01:41 UTC 
In the Linux kernel, the following vulnerability has been resolved:

iommu/vt-d: Block PASID attachment to nested domain with dirty tracking

Kernel lacks dirty tracking support on nested domain attached to PASID,
fails the attachment early if nesting parent domain is dirty tracking
configured, otherwise dirty pages would be lost.
