  "description": "In the Linux kernel, the following vulnerability has been resolved:  iommu: Fix NULL group-\u003Edomain dereference in pci_dev_reset_iommu_done()  Local sashiko review pointed it out that group-\u003Edomain could be NULL when a default domain fails to allocate during the first probe, which can crash at domain-\u003Eops-\u003Eattach_dev dereference in __iommu_attach_device() invoked by pci_dev_reset_iommu_done().  pci_dev_reset_iommu_prepare() is fine as an old_domain pointer can be NULL.  Skip the re-attach in pci_dev_reset_iommu_done() to fix the bug.",
