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: Call trace:
