CVE-2026-68395

In the Linux kernel, the following vulnerability has been resolved:

ata: satadwc460ex: enable SATA interrupts only after IRQ handler is registered

satadwcenableinterrupts() is called before platformgetirq() and atahost_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 satadwcenableinterrupts() after atahost_activate() so that interrupts are only unmasked once the handler is registered and the core is fully initialized.
