CVE-2026-53372 Details
Description
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.
A vulnerability in the Linux kernel's IOMMU (Input-Output Memory Management Unit) handling can lead to issues with PASID (Process Address Space ID) attachment in nested domains that have dirty tracking enabled. The kernel does not support dirty tracking for nested domains attached to PASID, and it fails the attachment process if the parent domain is configured for dirty tracking. This oversight can result in the loss of dirty pages.
Users can update to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the patched version are available on the Linux kernel's official website.
