  "description": "In the Linux kernel, the following vulnerability has been resolved:  PCI: plda: Fix IRQ domain leaks in the error paths of plda_init_interrupts()  plda_init_interrupts() initializes IRQ domains and creates IRQ mapping but does not unwind them when later step fails.  If platform_get_irq() or either irq_create_mapping() fails in plda_init_interrupts(), the domains are never deinitialized. If irq_create_mapping() fails, port-\u003Eintx_irq stays initialized.  Hence, remove the IRQ domains in the error path by calling plda_pcie_irq_domain_deinit().  Since plda_pcie_irq_domain_deinit() now disposes of the intx_irq and msi_irq mappings itself before removing their domains, the msi_irq mapping failure path can go directly to err_irq_domain_deinit instead of disposing of port-\u003Eintx_irq separately first.
