      "title": "PCI: mediatek: Fix IRQ domain leak when port fails to enable",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nPCI: mediatek: Fix IRQ domain leak when port fails to enable\n\nWhen mtk_pcie_enable_port() fails, mtk_pcie_port_free() removes the port\nfrom pcie->ports and frees the port structure. However, the IRQ domains set\nup earlier by mtk_pcie_init_irq_domain() are never freed.\n\nFix this by refactoring mtk_pcie_irq_teardown() into a per-port helper,\nmtk_pcie_irq_teardown_port(), and calling it from mtk_pcie_setup() when\nmtk_pcie_enable_port() fails. Since the IRQ teardown must only happen in\nthe probe error path (during resume, child devices may have active MSI\nmappings and the NOIRQ context prohibits sleeping locks),\nmtk_pcie_enable_port() is changed to return an error code so callers can\ndistinguish the two paths and act accordingly.\n\nThis issue was reported by Sashiko while reviewing the EcoNet EN7528 SoC\nsupport series.",
