Details

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:
