Description

In the Linux kernel, the following vulnerability has been resolved: gpio: mvebu: free generic chips on unbind irq_alloc_domain_generic_chips() allocates generic chip data that must be freed via irq_domain_remove_generic_chips(). The devres action mvebu_gpio_remove_irq_domain() only called irq_domain_remove(), which only frees the generic chips if IRQ_DOMAIN_FLAG_DESTROY_GC is set. Call irq_domain_remove_generic_chips() explicitly before irq_domain_remove() instead.

Affected products

• Linux kernel: from 3.16.40 before 3.17; from 4.8.9 before 4.9; 4.9 — fixed in 3.17, 4.9, 7.2
