"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: mxc: fix race between chained IRQ handler install and probe completion\n\nmxc_update_irq_chained_handler() is called before the IRQ domain, the\ngeneric IRQ chip, and the port list entry are set up. If an interrupt\narrives in that window:\n\n - mx3_gpio_irq_handler() calls generic_handle_domain_irq() with\n port->domain still NULL.\n - mx2_gpio_irq_handler() walks mxc_gpio_ports, but the port has not\n been added to the list yet.\n\nAdditionally, if any of the subsequent probe steps\n(gpio_generic_chip_init(), devm_gpiochip_add_data(),\nirq_domain_create_legacy(), or mxc_gpio_init_gc()) fail, the error\npaths never unregister the chained handler, leaving a dangling handler\nthat points at freed memory.\n\nMove the handler installation after all its dependencies are ready and\nafter list_add_tail(), so the handler is never live while the data\nstructures it touches are incomplete, and is never installed if probe\nfails."
