Vulnerability Title
gpio: rockchip: fix generic IRQ chip leak on remove
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: gpio: rockchip: fix generic IRQ chip leak on remove The driver allocates domain generic chips using irq_alloc_domain_generic_chips() during probe. However, on driver remove/teardown, the generic chips are not automatically freed when the IRQ domain is removed because the domain flags do not include IRQ_DOMAIN_FLAG_DESTROY_GC. This causes both the domain generic chips structure and the associated generic chips to be leaked. Additionally, the generic chips remain on the global gc_list and may later be visited by generic IRQ chip suspend, resume, or shutdown callbacks after the GPIO bank has been removed, potentially resulting in a use-after-free and kernel crash. Fix the resource leak by explicitly calling irq_domain_remove_generic_chips() before removing the IRQ domain in rockchip_gpio_remove().
