CVE-2026-90123

A flaw was found in the Linux kernel's irqchip/ast2700-intc component. An invalid memory allocation attempt occurs within the irqdomainactivate callback while interrupts are disabled and a spinlock is held. This condition, triggered by the fwnodedeviceiscompatible function, can lead to system...

CVE-2026-90123

CVE-2026-90123 affects the Linux kernel irqchip/ast2700-intc driver (Aspeed AST2700 interrupt controller). The root cause is that fwnode_device_is_compatible() performs a GFP_KERNEL memory allocation, which is unsafe in the irq_domain_activate() callback context — a path invoked from __setup_irq(...
