Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the iommu/vt-d component where the system relies on the pci dev is disconnected() function to skip Address Translation Services (ATS) invalidation for safely removed devices. This approach fails to account for link-down events caused by faults, which can lead to a system hard-lockup. This scenario can occur, for example, when a virtual machine fails to connect to a PCIe device and resources are released via "virsh destroy". The issue is related to the qi flush dev iotlb() function and the devtlb invalidation with pasid() process.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
