Description OSIDB Bzimport 2026-08-15 06:08:34 UTC 
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.
