Title
dmaengine: dw-edma: Initialize IRQ data before requesting IRQs
Summary
In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: Initialize IRQ data before requesting IRQs dw_edma_irq_request() passes struct dw_edma_irq to request_irq() before dw_edma_channel_setup() fills the back pointer. A shared interrupt can therefore enter the handler with dw_irq->dw still NULL, leading to a NULL pointer dereference. Set the back pointer before installing each handler.
Severity
No CVSS data available.
