  "summary": "gpio: rockchip: fix generic IRQ chip leak on remove",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: rockchip: fix generic IRQ chip leak on remove\n\nThe driver allocates domain generic chips using\nirq_alloc_domain_generic_chips() during probe. However, on driver\nremove/teardown, the generic chips are not automatically freed when the\nIRQ domain is removed because the domain flags do not include\nIRQ_DOMAIN_FLAG_DESTROY_GC.\n\nThis causes both the domain generic chips structure and the associated\ngeneric chips to be leaked. Additionally, the generic chips remain on\nthe global gc_list and may later be visited by generic IRQ chip suspend,\nresume, or shutdown callbacks after the GPIO bank has been removed,\npotentially resulting in a use-after-free and kernel crash.\n\nFix the resource leak by explicitly calling\nirq_domain_remove_generic_chips() before removing the IRQ domain in\nrockchip_gpio_remove().",
