In the Linux kernel, the following vulnerability has been resolved:
dmaengine: fsl-qdma: init irq after reg initialization
Initialize the qDMA irqs after the registers are configured so that
interrupts that may have been pending from a primary kernel don't get
processed by the irq handler before it is ready to and cause panic with
the following trace:
