What the advisory describes

In the Linux kernel, the following vulnerability has been resolved: irqchip/ast2700-intc: Avoid allocating in the irq_domain activate() callback The interrupt core calls the irq_domain_activate() callback from __setup_irq() with desc->lock held and interrupts disabled. Both aspeed_intc1_irq_domain_activate() and aspeed_intc0_resolve_route() test a compatible string with fwnode_device_is_compatible(). fwnode_device_is_compatible() invokes fwnode_property_match_string(), which allocates with GFP_KERNEL. That's obviously not possible with interrupts disabled and a raw spinlock held. Both call sites are only ever handed OF nodes, so use of_device_is_compatible() instead: it walks the property in place and does not allocate.

Source: EUVD (ENISA), in the words of the advisory.
