Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iommu/vt-d: Fix potential memory leak in intel_setup_irq_remapping()<br /> <br /> After commit e3beca48a45b ("irqdomain/treewide: Keep firmware node<br /> unconditionally allocated"). For tear down scenario, fn is only freed<br /> after fail to allocate ir_domain, though it also should be freed in case<br /> dmar_enable_qi returns error.<br /> <br /> Besides free fn, irq_domain and ir_msi_domain need to be removed as well<br /> if intel_setup_irq_remapping fails to enable queued invalidation.<br /> <br /> Improve the rewinding path by add out_free_ir_domain and out_free_fwnode<br /> lables per Baolu&amp;#39;s suggestion.
