Summary
In the Linux kernel, the following vulnerability has been resolved:
ata: sata_dwc_460ex: enable SATA interrupts only after IRQ handler is registered
sata_dwc_enable_interrupts() is called before platform_get_irq() and
ata_host_activate(), leaving the SATA controller's interrupt mask
enabled without a registered handler. If a later step fails (irq
request, phy init, etc.) or if the controller asserts an interrupt
during probe, the irq line may fire with no handler, causing a
spurious interrupt storm.
Move sata_dwc_enable_interrupts() after ata_host_activate() so that
interrupts are only unmasked once the handler is registered and the
core is fully initialized.
