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().
