Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> PCI: mediatek: Fix IRQ domain leak when port fails to enable<br /> <br /> When mtk_pcie_enable_port() fails, mtk_pcie_port_free() removes the port<br /> from pcie-&gt;ports and frees the port structure. However, the IRQ domains set<br /> up earlier by mtk_pcie_init_irq_domain() are never freed.<br /> <br /> Fix this by refactoring mtk_pcie_irq_teardown() into a per-port helper,<br /> mtk_pcie_irq_teardown_port(), and calling it from mtk_pcie_setup() when<br /> mtk_pcie_enable_port() fails. Since the IRQ teardown must only happen in<br /> the probe error path (during resume, child devices may have active MSI<br /> mappings and the NOIRQ context prohibits sleeping locks),<br /> mtk_pcie_enable_port() is changed to return an error code so callers can<br /> distinguish the two paths and act accordingly.<br /> <br /> This issue was reported by Sashiko while reviewing the EcoNet EN7528 SoC<br /> support series.
